Chapter 1 Overview
1.1 Introduction to the V210 IPRAN
In V210, the Iub, Iur, and Iu interfaces are carried over the IP transport network.
An operator can use the existing IP networks for the transport expansion. The
network construction cost is saved. In addition, the IP network provides a variety
of access modes and provides the sufficient transport bandwidth for high speed
data services (for example, HSDPA).
2008-09-14 Huawei Confidential Page 9 of 139
IPRAN Deployment Guide INTERNAL
With the comparison to V18 and V29, the new IPRAN functions in the V210 are
as follows:
1.1.1 FP MUX
1. Principles
The frame protocol multiplexing (FPMUX) multiplexes several small FP PDU
frames (sub-frame) that should be transmitted independently to one UDP/IP
frame header. As a result, a number of UDP/IP headers are saved. Hence, the
transport efficiency increases.
The FP MUX is applicable to only the user plane in the IPRAN Iub interface.
2. Protocol
The FP MUX is the protocol defined by Huawei.
3. Command
//At the RNC side:
ADD IPPATH: FPMUX=YES, SUBFRLEN=127, MAXFRAMELEN=270,
FPTIME=2;
By default, the FP MUX is disabled.
After the FP MUX is enabled, the default parameters are as follows:
FPMux maximum sub frame length (SUBFRLEN)=127Bytes
FPMux maximum multiplexing frame length (MAXFRAMELEN)=127Bytes
Multiplexing maximum delay (FPTIME) =2ms
// At the NodeB side:
ADD IPPATH: SRN=0, SN=6, SBT=BASE_BOARD, PT=ETH,
JNRSCGRP=DISABLE, FPMUXSWITCH=ENABLE, SUBFRAMELEN=127,
FRAMELEN=270, TIMER=1;
By default, the FP MUX is disabled.
After the FP MUX is enabled, the default parameters are as follows:
FPMux maximum sub frame length (SUBFRAMELEN)=127Bytes
FPMux maximum multiplexing frame length (FRAMELEN)=127Bytes
Multiplexing maximum delay (TIMER) = 1ms

1.1.2 IPRAN Header Compression
1. Principles
The IPRAN header compression improves the transport efficiency by
compressing partial fields of PPP frames.
Figure 1-1 PPP frame format
The PPP frame header compression algorithm implements the following:
Address and control field compression (ACFC): The address and control field
is the constant value (0XFF03) and is not transported every time. After the
PPP link is configured with the Link Control Protocol (LCP), the subsequent
packet address and control fields can be compressed.
Protocol field compression (PFC): The PFC can compress two-byte protocol
field to one byte. The system judges whether the protocol field is one byte or
two bytes according to the last significant bit (LSB) of the first byte in the
protocol field. If the LSB is 1, it indicates that the protocol field is two bytes in
length. If the LSB is 0, it indicates that the protocol field is only one byte in
length. For example, the first byte of the protocol field is 0x00, it can be
compressed.
IP Header Compression (IPHC): The IPHC compresses the IP/UDP header
of the PPP frame.
Figure 1-2 IPHC compression range
2008-09-14 Huawei Confidential Page 11 of 139
IPRAN Deployment Guide INTERNAL
IPHC principles:
1) The header field remaining unchanged is not carried in each packet that
is sent. The header field changed according to the designated mode can
be replaced by fewer bits.
2) If the header context of the packet stream is established at both ends of
a link, only the changed header field and the corresponding context tag
are transferred. The original header can be recovered according to the
context and changed fields.
Terms:
Context: It is the status table of the synchronization maintenance of the same
packet stream by the compresser and decompresser. The compresser uses
it to compress the packet header. The decompresser uses it to recover the
compressed packet header.
2. Protocol
ACFC: RFC 1661
PFC: RFC 1661
IPHC: RFC 2507 and RFC 3544
3. Command
At the RNC side:
ADD PPPLNK: MUX=Disable, IPHC=UDP/IP_HC, PFC=Enable, ACFC=Enable;
By default, three algorithms are enabled.
At the NodeB side:
ADD PPPLNK: IPHC=ENABLE, PFC=ENABLE, ACFC=ENABLE;
By default, three algorithms are enabled.
1.1.3 IPRAN Fault Detection
1. Principles
At present, the RNC supports the ARP detection and BFD detection for detecting
the transport link from the RNC to the peer equipment:
Address resolution protocol (ARP) detection
2008-09-14 Huawei Confidential Page 12 of 139
IPRAN Deployment Guide INTERNAL
The system determines the continuity of the link according to the response of the
peer equipment by sending ARP requests to the peer equipment. Every the fixed
duration, the RNC constructs an ARP request packet to send to the network. The
destination address of the packet is the peer address to be detected. The RNC
determines the continuity of the link by judging whether the response from the
destination address is received.
The ARP detection is applicable to only the direct connection detection whose
both ends are on the same network segment.
Features of the ARP detection are as follows:
The ARP is the basic protocol, without depending on the peer equipment.
The detection starts at one single end.
The detection state is related to the port state. The port switchover is
triggered if a fault is detected. The system deletes the route whose detection
address is the next hop. The upper layer service selects other available
channels.
The ARP detection supports the independent port detection, only active port
detection, and active/standby port simultaneous detection.
When the active and standby ports are detected at the same time, the IP
address of the active and standby ports should not be on the same network
segment.
Bidirectional forwarding detection (BFD)
The method of the BFD detecting the link continuity: The system originates the
handshake packets from both ends and determines the link continuity according
to the handshake result (success or failure).
The V210 RNC implements the single-hop BFD (SBFD) and multi-hop BFD
(MBFD):
SBFD:
The SBFD is applicable to only the direct connection detection whose both ends
are on the same network segment, which is the same as the ARP detection. The
features of the SBFD are as follows:
The both ends must start at the same time. The detection duration at both
ends must be configured to be equivalent. At present, only the asynchronous
mode is supported.
The detection state is related to the port state. The port switchover is
triggered if a fault is detected. The system deletes the route whose detection
2008-09-14 Huawei Confidential Page 13 of 139
IPRAN Deployment Guide INTERNAL
address is the next hop. The upper layer service selects other available
channels.
The independent port detection is supported. Only the active port is detected.
The active/standby port simultaneous detection is not supported.
MBFD:
The MBFD is applicable to the non direct connection end-to-end detection in the
scenario where signals pass more than one network nodes. The features of the
MBFD are as follows:
The both ends must start at the same time. The detection duration at both
ends must be configured to be equivalent. At present, only the asynchronous
mode is supported.
The detection state is not associated. If a fault is detected, only an alarm is
reported.
The MBFD does not depend on a port. The IP (DEVIP or ETHIP) of the
active and standby boards can be used as the local address of the multi-hop
BFD. In addition, the peer IP address and any local IP address should not be
on the same network segment.

MTP3 User Adaption Layer (M3UA): It is the adaption layer protocol of MTP level-
3 users. The M3UA provides the conversion between the signaling point code
(SPC) and IP address. The M3UA is applicable to the transmission of the SS7
protocol between the SoftSwitch and signaling gateway (SG). The M3UA
supports the transmission of MTP level-3 user message in the IP network,
including but not limited to, ISUP, TUP, and SCCP messages. The RANAP is the
SCCP user protocol. Their messages are transparently transmitted in the M3UA
protocol layer as the SCCP payload.
Concepts related to the M3UA:
Application server (AS): It serves the logical entity of specific routing keywords.
The AS processes the call procedure of all SCN trunks identified by SS7 SIO,
DPC, OPC, and CIC. The AS contains a group of unique AS process, among
them, one or two are in the active state.
2008-09-14 Huawei Confidential Page 20 of 139
IPRAN Deployment Guide INTERNAL
Application server process (ASP): It is the process instance of the AS. One
ASP functions as one active or standby process of the AS. One ASP contains
one SCTP endpoint and may be configured to process signaling services in one
or more ASs.
IP server process (IPSP): It is the process instance based on the IP application.
Essentially, the IPSP is the same as the ASP. The IPSP uses the point to point
M3UA, instead of SG services.
Signaling gateway (SG): It is the signaling proxy for receiving and sending
signaling messages at the edge between the SS7 network and IP network.
Signaling gateway process (SGP): It is an instance of the signaling gateway
process. The SGP is the activation, backup, load-sharing, or broadcast process
of the signaling gateway.
Switched Circuit Network (SCN): It is the network carrying services by using
the channel with the pre-defined bandwidth.
Media gateway (MG): When a media stream flows from the SCN to the PS
network, the MG terminates the SCN media stream and packs media data (if
media data is not based on the data packet form), and transfers the packed
service to the packet-based network. When a media stream flows from the PS
network to the SCN, the system implements the reversal procedure.
Media gateway controller (MGC): The MGC is responsible for processing the
resource registration and management on the MG.
2.1.3 Functions of the M3UA
Functions of the M3UA are as follows:
Supporting the transport of all MTP3 user message (ISUP, TUP, or SCCP)
Supporting the seamless interaction of the same MTP3 user protocol in
different networks (for example, the interaction between the ISUP in the SCN
and the ISUP in the IP network)
Supporting the SCTP connection and service management between the SG
and MGC (or the database in the IP network), and between IPSPs
Supporting the redundancy protection (active/standby connection or load
sharing) between the SG and MGC (or the database in the IP network), and
between IPSPs
Supporting the interworking capability of the MTP3 network management
function and address translation mapping (SS7<->IP)

2.1.4 Protocol
RFC 3332
2.1.5 Configuration Sequence at the RNC Side
The configuration sequence at the RNC side is as follows:
(OPC --> N7DPC )--> M3LE --> M3DE --> M3LKS --> M3RT --> M3LNK
2.2 SCTP
For the SCTP principles, see V18 Deployment Guide. This section describes the
multi-homed SCTP.
2.2.1 Principles of Multi-Homed SCTP
The multi-homed SCTP means that one device has multiple IP addresses.
Figure 2-1 Principle of multi-home
Path: It is the route of data transmission. In the IP network, the transmission path is
related to the destination IP address and the source IP address. Actually, a path is
2008-09-14 Huawei Confidential Page 22 of 139
IPRAN Deployment Guide INTERNAL
determined by the destination address and source address. The SCTP supports the
multi-home, that is, multiple IP addresses can be used for the transport. The
conservative policy is used. In the case of the connection setup, the system selects
one active path (active source address and active destination address) for the
transport. When the active path is unreachable or the retransmission is required,
another path is used.
Multi-homed endpoint: In one endpoint, if multiple transport addresses are used as
the destination address, the endpoint is considered as the multi-homed endpoint.
2.2.2 SCTP Dual-Homed Mechanism Supported by the RNC
The multi-homed SCTP supported by V210 RNC refers to two local addresses and
two peer addresses. As shown in Figure 2-2, the local system has IP A and IP B,
and the peer system has IP 1 and IP 2.
Active destination address:
The Path is maintained by maintaining the state of the destination address. In the
case of multiple destination addresses, one active destination address is maintained.
The active destination address is preferred for sending data.
Maintenance path:
At present, only two maintenance paths are available. When one is unavailable, the
system finds the next available path through sending the heartbeat. In the path that
is not maintained, the system does not send the heartbeat actively.
2.2.3 Protocol
For the relevant protocol, see the RFC2960. For the dual-homed SCTP, see "6.4
Multi-homed SCTP Endpoints".
2.3 Others
For the principles of the TCP, UDP, PPP, ARP, NAT, VLAN, and TRACERT, see

Chapter 3 Introduction to the Networking
3.1 V2 Backup Policy
3.1.1 Backup Mode at the RNC Side
Two backup modes are available in the RNC: board backup and port backup
Board backup
In the board backup mode, one board is active and the other is standby. The service
can be processed by the active board or by active and standby boards. When the
active board is faulty, the RNC automatically originates the switchover of the
active/standby boards.
Port backup
In the port backup mode, one port is active and the other is standby. Services are
transported through the active port only. When the active port is faulty, the RNC
automatically originates the switchover of the active/standby ports.
1. Board backup mode
With the comparison to V29, the board backup and port backup in V210 are
independent. If only the board backup is configured, without configuring the port
backup, the board is switched over only when the board is faulty.
In the board backup mode, one board is active and the other is standby. The service
can be processed by the active board or by active and standby boards (that is, the
board is in the active/standby mode and the port is in the load sharing mode).
When the active board is faulty, the RNC automatically originates the switchover of
active/standby board.
You can set the board backup relation by running ADD BRD. If Backup is set to Yes,
the board backup applies.
2. Port backup mode
FG2a and GOUa boards
2008-09-14 Huawei Confidential Page 24 of 139
IPRAN Deployment Guide INTERNAL
When the active/standby slots in the RNC subrack are configured with two
FG2a/GOUa boards, two FG2a/GOUa boards can be set to Board backup;port not
backup, or board and port backup.
When FG2a/GOUa boards are set to the board backup, you can configure the FE/GE
port backup by running ADD ETHREDPORT.
If the port backup is not configured and only the board backup is configured, the
board backup and port load-sharing mode applies.
With the comparison to V29, the Board and port backup bonding is reduced in the IP
interface board for the backup mode in V210, and only Board and port backup apart
and the board backup and port load sharing mode are available in V210.
UOIa_IP and POUa boards
When the UOIa is in the board backup mode, the corresponding optical ports (for
example, optical port 0 in the active board and optical port 0 in the standby board) in
active/standby UOIa are also backed up. The backup mode is MSP 1:1 or MSP 1+1
(single end or dual ends).
When the optical interface of the UOIa is in MSP 1:1 backup, one optical port is
active, and the other optical port is standby. The active optical port is responsible for
receiving and transmitting data.
In the case of the MSP 1+1 backup of the optical port in the UOIa board, one optical
interface is active and the other is standby. The data processing of the backup mode:
The active and standby optical ports send data at the same time, and only the active
optical port receives data.
To set the relevant attributes of the MSP backup, run SET MSP. MSP attributes
include Revertive type, WTR Time (required only when Revertive type is set to
REVERTIVE), K2 Mode, SDSF Priority, and Backup mode. The settings of these
parameters must be consistent with those at the peer end through negotiation.
3. Impact on the system by the switchover
When the FG2a/GOUa adopts the board backup without the port backup, the
switchover of the active/standby board has not impact on existing services.
When the FG2a/GOUa adopts the board backup and port backup, the switchover of
the active/standby board has the slight impact on the data transport. The existing
service is not interrupted.
If the data traffic of the optical interface is large, the switchover of the active/standby
UOIa board has the slight impact on the data transport. The existing service is not
interrupted.

IPRAN Deployment Guide INTERNAL
3.1.2 NodeB Side
1. NodeB supports only the board backup mode, without supporting the port backup mode
In the board backup mode, data is configured and processed only in the active
board, and the standby board is in the monitoring status. When all used physical
links in the active board is in the unavailable state (For example, E1 has the LOS
alarm and the FE port is DOWN) and a physical link is available in the standby
board, the board can be switched over. In the case of the switchover, the active
and standby boards are restarted. When the configurations of the active board
are loaded to the standby board, the standby board is upgraded to the active
board. In the case of the switchover, the service is interrupted.
In the configuration of the board backup mode, only the CME can be used to
generate the configuration file. To query the current board mode, run LST
IUBGRP in the LMT. If the board is not configured to the active/standby mode,
you can perform configurations by running commands. The specific configuration
modes are as follows:

3.3 Backup Constraint
3.3.1 RNC
1) In the separate mode, the route must be configured in even slots.
2) The backup mode should not be configured in odd slots.
3) After the active/standby Ethernet ports are configured, the corresponding
ports of the active/standby boards function as the active/standby ports.
4) The backup port should not be used. The gateway continuity check can
be started.
5) When at least either of the active and standby ports is configured with IP
or port control, two ports are not allowed to be configured as the active
and standby ports.
3.3.2 NodeB:
1) Boards supporting the board backup:
V210: WMPT/UTRP
V110: NUTI/HBBU. NDTI does not support.
2) The code backup is performed in the NodeB. Hence, the service is
interrupted in the case of the switchover.
3) In the backup mode, data is configured only in the active board. By default,
the slot with the smaller ID in the backup group is the active board in the
initial configuration.

4.1.2 NodeB Side
1. Set the Ethernet port attribute
Command: SET ETHPORT
Set the work mode of the FE port: The work mode at both ends for the
interconnection must be consistent.
2. Set the priority of the signaling and OM
Command: SET DIFPRI
Related parameters are as follows:
Name Description
Priority Rule Value range: IPPRECEDENCE,DSCP
Signal Priority Value range:0 - 7: when PRIRULE is IPPRECEDENCE,0 - 63: when PRIRULE is DSCP.
OM Priority Value range:0 - 7: when PRIRULE is IPPRECEDENCE,0 - 63: when PRIRULE is DSCP.
The relations between the signaling, service, and DSCP values are as follows:
1) Iub interface signaling data
2008-09-14 Huawei Confidential Page 41 of 139
IPRAN Deployment Guide INTERNAL
Signaling data over Iub interface is transported with SCTP. The sending of the
DSCP priority in the SCTP protocol package is determined by the DSCP in the
Signaling Priority type by running SET DIFPRI.
2) Common channel
The common channel transports control information, with the higher priority. The
priority is equivalent to the NCP/CCP data. For services in the common channel,
data from the RNC to the NodeB is transmitted through the DSCP on the RT
PATH. The data returned from the NodeB to the RNC is transmitted through the
DSCP of the Signal Priority by running SET DIFPRI.
3) R99 service (user voice and PS network access data)
The NodeB sends the DSCP priority of these UDP packages. When the
connection is established, the RNC notifies the NodeB. The DSCP settings are
determined by the RNC.
4) HSDPA
Data from the RNC to the NodeB is the downloaded data. The DSCP value of the
HSDPA_IPPATH configured by the RNC determines the DSCP for the data
transmitting. The flow control information frame returned from the NodeB to the
RNC is uploaded by using the DSCP value of the Signal Priority configured by
running SET DIFPRI.
5) HSUPA
The data from the NodeB to the RNC and data from the RNC to the NodeB are
transmitted by using the DSCP value sent in the case of the RNC link setup.
6) OM maintenance data
The OM maintenance data is transported through the TCP. The sending of the
DSCP priority in the packages is determined by the DSCP in the OM type by
running SET DIFPRI.
Precautions for the configuration:
1) Priority Rule: It has two options: IPPRECEDENCE and DSCP. The
recommended configuration is DSCP. The IPPRECEDENCE is labeled by using
the priority field in the type of service (TOS) field in the IP header. The DSCP is
configured according to the DSCP value of the Diffserv.
One IPPRECEDENCE corresponds to a range of the DSCP value.
DSCP range: [A,B) Specific value:
2008-09-14 Huawei Confidential Page 42 of 139
IPRAN Deployment Guide INTERNAL
I PPRECEDENCE DSCP0 000000~0010001 001000~0100002 010000~0110003 011000~1000004 100000~1010005 101000~1100006 110000~1110007 111000~111111
2) The SIG precedence is configured to be consistent with the DSCP value of the
SCTP in the RNC.
3. Set the configuration between the DSCP and VLAN
Command: SET VLANCLASS
In the VLAN configurations, the VLANIDs vary with protocol types. The NodeB
distinguishes according to the following rules:
Protocol type = SCTP: Iub interface signaling data includes only the NCP/CCP
data. Correspond to the SIG class by running the command SET VLANCLASS.
SET VLANCLASS: VLANGROUPNO=X, TRAFFIC=SIG, INSTAG=ENABLE,
VLANID=X, VLANPRIO=X;
Protocol type = UDP: Voice, PS network access, and H download. It applies to data
of common channels. In addition, the local UDP port number is in the legal range of
the NodeB. It corresponds to USERDATA class by running the command SET
VLANCLASS.
SET VLANCLASS: VLANGROUPNO=X, TRAFFIC=USERDATA, SRVPRIO=X,
INSTAG=ENABLE, VLANID=X, VLANPRIO=0;
Protocol type = UDP: The local UDP port number is not in the legal range of the
NodeB. It is other applications (for example, TRACERT). It corresponds to OTHER
class by running the command SET VLANCLASS.
SET VLANCLASS: VLANGROUPNO=X, TRAFFIC=OTHER, INSTAG=ENABLE,
VLANID=X, VLANPRIO=X;
Protocol type = TCP: Data of OM management and maintenance. It corresponds to
the OM class by running the command SET VLANCLASS.
Protocol type = Others: Includes, but not limited to, ICMP, ARP, and DHCP. The
value is treated as other types. It corresponds to the OM class by running the
command SET VLANCLASS.
2008-09-14 Huawei Confidential Page 43 of 139
IPRAN Deployment Guide INTERNAL
SET VLANCLASS: VLANGROUPNO=X, TRAFFIC=OM, INSTAG=ENABLE,
VLANID=X, VLANPRIO=X;
4. Set the VLAN based on the next hop (V210)
Command: ADD VLANMAP
Set the VLANID based on the next hop (V210). The configuration methods are as
follows:
1) All data is labeled with the same VLAN.
When running the command ADD VLANMAP, select the single VLAN for the
VLANMODE. That is, all data with the same next hop address is labeled with the
VLAN.
ADD VLANMAP: NEXTHOPIP="12.13.14.15", VLANMODE=SINGLEVLAN,
INSTAG=ENABLE, VLANID=100, VLANPRIO=1;
2) Label different VLANs according to data types
When running the command ADD VLANMAP, select VLANGRP for the VLANMODE.
To set the VLAN in the VLANGRP, run SET VLANCLASS.
ADD VLANMAP: NEXTHOPIP="12.13.14.15", VLANMODE=VLANGROUP,
VLANGROUPNO=0;
According to the correspondence between the service and DSCP, the signaling at the
NodeB side, uplink frame of the common channel, the uplink control frame of the
HSDPA use the DSCP value of the SIG type by running the command SET DIFPRI.
The signaling uses the SCTP. The uplink frame of the common channel and the
uplink control frame of the HSDPA use the UDP. Hence, the VLANs should be set
respectively.
5. Example
SET DIFPRI: PRIRULE=DSCP, SIGPRI=48, OMPRI=20;
VLAN configuration of the signaling:
SET VLANCLASS: VLANGROUPNO=0, TRAFFIC=SIG, INSTAG=ENABLE,
VLANID=100, VLANPRIO=6;
VLAN configuration of the uplink frame of the common channel and the uplink control
frame of the HSDPA
SET VLANCLASS: VLANGROUPNO=0, TRAFFIC=USERDATA, SRVPRIO=48,
INSTAG=ENABLE, VLANID=2, VLANPRIO=5;
2008-09-14 Huawei Confidential Page 44 of 139
IPRAN Deployment Guide INTERNAL
If the priority rule by running the command SET DIFPRI is IPPRECEDENCE, use one
value in the DSCP range corresponding to the IPPRCEDENCE by running the
command SET VLANCLASS.
Note: V110 does not support the label of the VLAN based on the next hop; therefore,
the command ADD VLANMAP does not apply. Enable the VLANTAG by running the
command SET ETHPORT. Then, run the command SET VLANCLASS. The
configuration method is the same as that by running the command SET VLANCLASS
in V210.
4.2 Constraint and Restrictions of IP Address and Configuration

Chapter 5 Example of Iub Interface Configuration
5.1 Version Description
RNC version: V210060
5.2 IUB Interface Protocol Stack
In the case of the Iub over IP, the compliant sequence in adding Iub interface data
should be consistent with the protocol structure, that is, from the lower layer to the
upper layer. Data is configured from the control plane to the user plane.
The following figure shows IP-based protocol stack of the Iub interface.
2008-09-14 Huawei Confidential Page 46 of 139
IPRAN Deployment Guide INTERNAL
Figure 5-1 Iub interface protocol stack
5.3 Data Planning
In the case of the IP transport, the interconnected data (unless otherwise specified) of
the Iub interface is obtained through the negotiation between the RNC and the
NodeB. Before configuring IP-based Iub interface data, confirm the following
information:
L2 networking or L3 networking
Ethernet-based transport, private line-based transport, or IP hybrid transport
The IP transport solutions vary with transport networks used in the Iub interface.
5.3.1 Data Planning in L2 Networking
This section describes the data planning in the case of the use of the FE. For the data
planning of PPP/MLPPP, see section 7.3.3.

The following figure shows the Ethernet-based IP planning.
If the load-sharing mode is not used and only one IP address is used at the RNC side, the
ETHIP of the FG2 can be used directly. The DEVIP should not be configured and used. In the
example, the DEVIP used in the SCTP and IPPATH local address is optional, and indicates
only the configuration and usage of the DEVIP.

5.3.4 Data Planning of Dual Stack Transport Networking
With the development of data services, especially with the introduction of HSDPA and
HSUPA, there is an increasing demand for bandwidth on the Iub interface. The transmission
based on ATM over E1, however, is expensive. Data services produce decreasing benefits for
telecom operators. Therefore, the telecom operators are eager for a low-cost Iub transmission
solution. In such a situation, ATM/IP dual stack transport is introduced. In addition to the
guarantee of services, this transport reduces costs of data transmission on the Iub interface.
Based on the Quality of Service (QoS) and bandwidth requirements, ATM/IP dual stack
transport implements data transmission as follows:
Voice, streaming, and signaling services have a relatively low requirement for the bandwidth and high requirement for the QoS. Such services are transmitted on ATM networks.
BE services and HSDPA/HSUPA services have a relatively high requirement for the bandwidth and low requirement for the QoS. Such services are transmitted on IP networks.
Note: The transmission paths carrying different services are configurable (depending on the
data planning).
2008-09-14 Huawei Confidential Page 63 of 139
IPRAN Deployment Guide INTERNAL
ATM/IP dual stack transport protects the investment of the existing ATM networks, reduces
the impact of IP transport on the ongoing services on the ATM networks, and meets the
requirements of telecom operators for highly efficient and low-cost networks and for flexible
networking.
1. Networking Description
The ATM/IP dual stack transport enables hybrid transport of services that have different QoS
requirements. The services of high QoS requirements, such as voice, streaming, and
signaling, are transmitted on the ATM network. The services of low QoS requirements, such
as HSDPA and HSUPA, are transmitted on the IP network.
Figure 5-1 Dual stack transport networking
To support this networking mode, an RSS or RBS of the RNC is configured with both ATM
and IP interface boards.
The ATM interface board can be an AEUa, AOUa, or UOIa (UOI_ATM). It is connected to the ATM network through the E1/T1 port, channelized STM-1 port, or OC-3C port.
The IP interface board can be an FG2a, GOUa, POUa, or UOIa (UOI_IP). It is connected to the IP network through the Ethernet port, E1/T1 port, channelized STM-1 port, or OC-3C port.
The NodeB is connected to the ATM and IP networks through its ATM and IP interface boards
respectively.
2. Networking Planning
Note: This configuration is based on the following scenarios: On the RNC side, the AOUa
serves as the ATM interface board and the FG2a serves as the IP interface board. The
signaling, R99 real-time (RT), and OM services are transmitted on the ATM network, and the
R99 non-real-time (NRT), HSDPA, and HSUPA services are transmitted on the IP network.
For dual backup channels of signaling and OM services, the related parameters should be
modified in the configuration.

5.4.3 Configuration of Hybrid Transport Networking
The port IP of the RNC interface board and the NodeB IP belong to different network
segments. Packets are forwarded to the NodeB through a router. In the case of the FE
bearer, use the FG2a board and port backup, with the switchover separation mode. Support
the port independent switchover. The dual reliabilities (board and transport) are provided.
The FG2a/GOUa board backup and port load sharing mode can be used. Through the route
configuration, the IP load sharing can be implemented between any two active FE/GE ports.
1. Connect E1 cables or Ethernet cables.
Label of hardware connection: The PEU board of the RNC is in slot 14/15 in subrack 0. The
FG2 is in slot 18/19 of subrack 0. The PPP LINK is carried over No.0 E1 pair (E1 is numbered
from 0), and the FE port is 0.
Signaling and real-time services are transmitted through the PPP, and BE services are
transmitted through the FE.
2. Perform the configuration in the RNC in the MML.
Configure the physical layer data. The configuration is not required in the case of E1
bearer.
Difference from the L2 networking: When physical layer data is configured, you should add
the device IP address of the board. The device IP address should not be the same as the
configured IP address in the RNC (including local/peer IP address of the PPP link, local/peer
IP address of the MLPPP group, Ethernet port IP address, IPPATH peer address, SCTP link
peer address).

6.6 IU/IUR Configuration Specifications
6.6.1 Configuration Specifications of Control Plane (IUPS-IP)
1. Difference of the configuration specifications between the M3UA and
Iu-CS: The RNC is the Client of the IPSP. The SGSN is the Server of
the IPSP. Other rules are the same as those of the Iu-CS.
2. The SCCP timer configuration specification is the same as that of the
Iu-CS.
6.6.2 Configuration Specifications of User Plane (IUPS-IP)
1. Each ETH PORT using the Iu-PS interface is configured with one IP
PATH. The type is QoS PATH.
2. If the peer device supports the function, enable the PING detection
function of the IP PATH.
3. Configure the bandwidth for the IP PATH. If the middle transport
bandwidth is smaller than the port bandwidth, the IP PATH bandwidth is
set to the transport bandwidth. If the transport bandwidth is not limited,
the IP PATH bandwidth is configured to the port bandwidth.
4. The port controller should distribute ports used in each subrack to all
SPU subsystems on average.
6.6.3 Configuration Specifications of Control Plane (IUCS-IP)
1. It is recommended that the context of the M3UA local entity route
should be set to 4294967295 (all F).
Note: If the peer system requires that the RNC must carry the route
context in ASP ACTIVE message, negotiate with the peer system about
the M3LE route context of the RNC.
2. The context of the destination entity route should be set to 4294967295
(all F).
2008-09-14 Huawei Confidential Page 114 of 139
IPRAN Deployment Guide INTERNAL
Note: If the peer system requires the negotiation, set the destination
entity route context according to the route context provided by the peer
system.
3. The service mode of the M3UA linkset requires the negotiation with the
peer system. The load-sharing mode is recommended (the
active/standby flag of initialized bearer service of the M3UA link is the
master mode). If the M3LE/M3DE is configured according to Table 2,
the work mode of the linkset is configured to IPSP. The precedence of
all links in the linkset must be the same.
4. RNC V29 binds the Client/Server of the M3UA with the Client/Server of
the SCTP. If the SCTP link used by the M3UA is the Server, the M3UA
is also the Server. If the SCTP link is Client, the M3UA is also the
Client. Configuration personnel should pay attention to this in the case
of the negotiation of the work mode of the SCTP/M3UA with the peer
system (in the IPSP-IPSP networking, the M3UA link in the Client mode
originates the link establishment of the M3UA link).
5. For the reliability, if the peer system supports the SCTP dual-home, all
SCTP links corresponding to the M3UA should be set to dual home
(each end uses two IPs).
6.6.4 Configuration Specifications of User Plane (IUCS-IP)
1. Each ETH PORT using the Iu-CS interface is configured with one IP
PATH. The type is QoS PATH.
2. If the peer device supports the function, enable the PING detection
function of the IP PATH.
3. Configure the bandwidth for the IP PATH. If the middle transport
bandwidth is smaller than the port bandwidth, the IP PATH bandwidth is
set to the transport bandwidth. If the transport bandwidth is not limited,
the IP PATH bandwidth is configured to the port bandwidth.
4. The port controller should distribute ports used in each subrack to all
SPU subsystems on average.
6.6.5 Configuration Specifications of Control Plane (IUR-IP)
1. The M3UA configuration specifications are the same as the Iu-PS.
2. The SCCP timer configuration specification is the same as that of the
Iu-CS.
2008-09-14 Huawei Confidential Page 115 of 139
IPRAN Deployment Guide INTERNAL
6.6.6 Configuration Specifications of User Plane (IUR-IP)
1. Each ETH PORT using the Iur interface is configured with one IP
PATH. The type is QoS PATH.
Note: For version earlier than V29C01B063, configure the IP PATH for
each NRNC user plane IP. That is, the network segment configuration
of the user plane IP is not supported.
2. If the peer device supports the function, enable the PING detection
function of the IP PATH.
3. Configure the bandwidth for the IP PATH. If the middle transport
bandwidth is smaller than the port bandwidth, the IP PATH bandwidth is
set to the transport bandwidth. If the transport bandwidth is not limited,
the IP PATH bandwidth is configured to the port bandwidth.
4. The port controller should distribute ports used in each subrack to all
SPU subsystems on average.
6.7 Relevant Knowledge Points
6.7.1 Two Modes
Work Mode
The concept is used in the M3UA linkset. The work mode must be negotiated
with the peer system, that is, specify who originates the link establishment. At
present, the link establishment is originated in the IPSP client and ASP mode. At
present, the work mode is applicable to only the linkset mode.
Traffic Mode
The traffic mode requires the negotiation with the peer system, for example,
AS. The information is carried in the ASP Active message. At the end where the
ASP Active message is received, the system compares Traffic Mode with Traffic
Mode configured at the peer system. If both are inconsistent, the system discards
this message and returns one ERROR (AS traffic mode is not matched). The
highest state of the AS can be only INACTIVE. The traffic mode cannot serve the
SCCP.

IPRAN Deployment Guide INTERNAL
6.7.2 Relation between Signaling Link and Mask
The signaling link mask of the M3UA linkset should meet the following two
conditions:
1) The number (n) of 1 in the mask determines the maximum number of links
(2^n) for the load sharing. The number of configured M3UA links must be smaller
than or equal to 2^n.
2) The AND operation between this value and Signaling Route Mask configured
in the N7DPC must be 0.
Number of Subracks
Number of M3UA Links
Signaling Link Mask
Remark
1 2 B0001 The SPU subsystem terminated in the M3UA should be distributed in subracks and SPMs on average. The bearer should be distributed on all ports of the Iu-CS on average.

Chapter 7 Remote O&M Channel
7.1 Maintaining the NodeB through the O&M Channel of the
RNC
7.1.1 Principles and Basic Configuration Procedures
Figure 7-1 shows the maintenance of the NodeB through the O&M channel of the
RNC.
Figure 7-1 Maintaining NodeB by the M2000 Through the RNC
Principles of maintaining NodeB through RNC
O&M packets are routed to the RNC from the M2000 directly. Data packets are
forwarded through the OMU and interface board in the RNC. After the arrival at the
interface board, packets are forwarded to the NodeB through the PPP/MLPPP/FE/GE.
General configuration procedures:
ADD EMSIP: Configure the EMS IP address.
ADD NODEBIP: Configure the NodeB O&M IP.
2008-09-14 Huawei Confidential Page 118 of 139
IPRAN Deployment Guide INTERNAL
If the transport type of the NodeB is IUB-ATM, Next hop IP address must be the
peer IP address of the IPOA PVC. If the transport type of the NodeB is IUB-IP, Next hop
IP address must be one of the following configured addresses:
PPP link peer IP address
MLPPP group peer IP address
IP address with the same network segment of the FE/GE port
ADD NODEBESN: If the DHCP function is used between the RNC and the NodeB,
add the NodeB electronic serial number to respond to DHCP requests reported by the
NodeB (Optional).
7.1.2 Configuration Example
1. The OM address of the NodeB and the NodeB interface address are on the same
network segment
Note: The OM address and interface address of the NodeB are on the same
network segment. At the NodeB side, you should run SET ETHPORT to enable
the ARP proxy function of the port.
Name Address
M2000 address 10.161.215.230
OMU external network address 10.161.215.211
OMU internal network address 80.168.6.40
FG2a internal address 80.168.6.64
FG2a interface address 12.12.8.1
NodeB interface address 12.12.8.2
NodeB OM address 12.12.8.11
ADD EMSIP: Configure the EMS IP address.
Command:
ADD EMSIP: EMSIP="10.161.215.230", MASK="255.255.0.0";
After the running of this command, the network segment route to the M2000 is
added to the FG2a interface board. The value of the network segment route is
the result with the AND operation between the address by running the command
ADD EMSIP and the mask. The results are as follows:

%%DSP IPRT: SRN=0, SN=18;%%
Destination address Address mask Next hop address
10.161.0.0 255.255.0.0 80.168.6.40
ADD NODEBIP: Configure the NodeB O&M IP.
Command:
ADD NODEBIP: NODEBID=1, NBTRANTP=IPTRANS_IP,
NBIPOAMIP="12.12.8.11", NBIPOAMMASK="255.255.0.0", IPSRN=0, IPSN=18,
IPGATEWAYIP="12.12.8.2", IPLOGPORTFLAG=NO;
After the running of this command, the RNC automatically adds the route to the
NodeB in the OMU. One host route is added. The results are as follows:
%%LST BAMIPRT:;%%
Destination network address Destination address mask Forward route address
12.12.8.11 255.255.255.255 80.168.6.64
ADD NODEBESN: Add the electronic serial number of the NodeB to respond to
DHCP requests reported by the NodeB (optional).
2. The OM address of the NodeB and the NodeB interface address are not on the same
network segment.
Assume that the OM address of the NodeB is changed to 10.10.10.10/24
1) The service is available; therefore, the service from the FG2a to NodeB
interface address is normal. The OM address of the NodeB and the interface
address are not on the same network segment; therefore, the route to the NodeB
is automatically added in the FG2a by running the command ADD NODEBIP.
ADD NODEBIP: NODEBID=1, NBTRANTP=IPTRANS_IP,
NBIPOAMIP="10.10.10.10", NBIPOAMMASK="255.255.0.0", IPSRN=0,
IPSN=18, IPGATEWAYIP="12.12.8.2", IPLOGPORTFLAG=NO;
The results (the network segment route added to the NodeB on the FG2a) are as
follows:
%%DSP IPRT: SRN=0, SN=18;%%
Destination address Address mask Next hop address
10.10.10.0 255.255.255.0 12.12.8.2
2) The M2000 can normally maintain the OMU; therefore, the path from the
M2000 to the OMU is normal.

IPRAN Deployment Guide INTERNAL
Note: In the EMS system, the route to the NodeB must be added. In the NodeB,
the route to the M2000 must be added.
Through the preceding configuration, the NodeB O&M channel in the RNC
is normal. You need not to configure any route in the RNC manually.
7.2 Maintaining the NodeB directly by the M2000
7.2.1 Principles and Basic Configuration Procedures
Figure 7-1 Maintaining the NodeB directly by the M2000
The OM channel from the M2000 to the NodeB does not pass the RNC. The
configurations are as follows:
Add the NodeB IP in the RNC: Add the NodeB IP for the M2000 to
provide the automatic search function (for the automatic search function of the
M2000, see the V8 IPRAN Deployment Guide).
Synchronize the M2000 to the RNC: Read the OMIP to the NodeB
from the BAM database and establish the OM channel with the NodeB.
If the OMIP of the NodeB and FE port are on the same network
segment. In the NodeB LMT, run SET ETHPORT to enable the ARP proxy function of
the port. Otherwise, one route to the NodeB OMIP must be added to Router2. The
next hop is the FE port address.

and Maintenance by the M2000 directly

Benefits It does not depend on the
transport network.
OM packets of the NodeB
do not cause extra burden
for the RNC.
The architecture is clear. A
fault can be located quickly.
Limitations The load of the RNC
increases.
The RNC cannot be isolated in
the location of a fault related to
the NodeB OM.
In special cases, a router is
required (for example, label
the VLAN).
Recommendation: In the IP networking, the direct maintenance of the NodeB by
the M2000 is recommended. The maintenance through the RNC is not
recommended. Thus, the occupation of the IUB transport resources decreases.
The load traffic between the RNC board decreases.
In special cases, the maintenance of the NodeB through the RNC is used. For
example, the IUB interface has the VLAN and a route device is unavailable for
labeling the VLAN.
7.4 Active/Standby OMCH Configurations at the NodeB Side
7.4.1 Basic Principles
The V210 is applicable to the dual stack. The IP scenario supports the
active/standby OMCH channel. The ATM scenario does not support the
active/standby configuration.
In the IP scenario, two remote maintenance channels can be configured. Two
channels reach the peer ends through different routes. After the NodeB starts, the
active channel is selected fixedly as the activation channel. If the active channel
is not available, the standby channel does not function as the activation channel
automatically. At this time, the results are null by running the command DSP
OMCH. In the initial configuration, one active OMCH channel must be configured.
Note:
1. The remote maintenance channel IP, local maintenance channel IP,
and IP of each interface (except the FE interface) should not be on the
same network segment. The local IP of two remote maintenance
channels should not be on the same network segment.
2008-09-14 Huawei Confidential Page 122 of 139
IPRAN Deployment Guide INTERNAL
2. If the peer IP and local IP of the maintenance channel are not on the
same network segment, you should run ADD OMCH to bind the route.
Only the binding route of the activation channel is valid. The binding
route of deactivation channel is not valid. Hence, the binding route is
used for this maintenance channel. Otherwise, the corresponding
binding route is invalid when the maintenance channel is switched over
to the deactivation channel. As a result, channels using the route are
interrupted. To ensure that the binding route of the maintenance
channel is used for this maintenance channel only, the destination
network segment of the binding route should be different from any route
destination network segment added by running the command ADD
IPRT. To query the configured route, run LST IPRT.
3. If the local IP of the OMCH and the FE address are on the same
network segment, run SET ETHPORT to enable the ARP proxy.
7.4.2 Configuration Example
1. Hybrid transport scenario
In the case of the hybrid transport, two OMCHs are configured: one is over the
ETH, and the other is over the PPP.
ADD OMCH: FLAG=MASTER, IP="12.12.8.11", MASK="255.255.255.0",

2. Dual-stack scenario
In the case of the dual-stack, two OMCHs are configured: one OMCH is over IP
and the configurations are the same as the previous IP scenario; the other OMCH
is over ATM.
ADD OMCH: FLAG=MASTER, IP="12.12.8.11", MASK="255.255.255.0",
PEERIP="10.161.215.230", PEERMASK="255.255.255.0", BEAR=IPV4, SRN=0,

Chapter 8 Remote Debug of
NodeB
8.1 NodeB Remote Software Debug
Usually, the NodeB software debug is subcontracted to a local cooperation
partner. The software debug is implemented at the local NodeB. The fee of the
NodeB software debug ranges from 1500 RMB to 7000 RMB.
To save this engineering cost, the remote debug for a NodeB is implemented in
the equipment room in the centralized mode. This mode can replace the debug at
the local NodeB. Benefits:
1. After the hardware of NodeB is installed, engineers need not enter
the site again.
2. The cost of the software debug is saved.
3. The construction speed of a NodeB is quicker.
After the transport of the Iub interface in the IPRAN is ready, two modes are
available for activating the NodeB remote maintenance channel:
Correct data configuration files are downloaded to the NodeB to
ensure the successful interconnection between the RNC and the
NodeB OM channel.
The DHCP is used to activate the NodeB remote OM channel when
correct data configuration files cannot be downloaded to the NodeB.
This section describes the remote debug of a NodeB related to Iub interface in
the IPRAN networking. Maintenance personnel use the M2000 or LMT debug a
NodeB in the remote OMC equipment room through the NodeB remote
maintenance channel.

8.2 Introduction to the DHCP
8.2.1 Basic Principles
The dynamic host configuration protocol (DHCP) transfers configuration
information (including allocated IP address, subnet mask, and default gateway)
for a host in the network. The DHCP is encapsulated through the UDP. Based on
the BOOTP protocol, the function of dynamically obtaining the IP address is
added. In packets, options are added.
Concepts:
DHCP Client: It is the host in the network using the DHCP obtain configuration
parameters, for example, NodeB.
DHCP Server: It is the host in the network returning configuration parameters to
the DHCP Client, for example, RNC
DHCP Relay: It is the device transferring DHCP packets between the DHCP
Server and the DHCP Client. The DHCP Relay can be a router or specific host.
8.2.2 Scenario without Using the DHCP Relay
When the L2 network exists between the NodeB (DHCP Client) and DHCP
Server, devices between them need not support the DHCP Relay.
The DHCP Server is the address of the RNC interface board. The L2 network
exists between the NodeB and RNC interface board. Figure 8-1 shows the DHCP
procedure.

Chapter 9 Troubleshooting
9.1 Troubleshooting related to the RNC
9.1.1 Using the Tracert for Analysis in the case of Failure to Ping Packets
1. Application scenario
When packets failed to be pinged or the delay is large, analyze the path of
packets to be pinged by using the Tracert. The displayed information indicates in
which gateway or path packets are delayed, and the delay time. The information
is helpful for locating the fault. For the Trace principles, see the V18 IPRAN
Deployment Guide.
2. Description
1) Run Tracert to query all path information from the PC to the peer device. For
example,
2) On the RNC: TRC IPADDR: SRN=0, SN=18, DESTIP="10.10.10.10";
3. Commands on the RNC
DSP ARP: Query the port ARP table.
DSP IPRT: Query the board route table

DSP ETHPORT: Query the port state and packet receiving and transmitting
9.1.2 Problems related to the SCTP
1. Principles
The data channel of the SCTP: SPU <--> PIU <--> Bearer network <--> Peer NE
When you locate the fault of the connection failure or one-way connection, you
should perform the following:
As shown in the dotted line in the preceding figure, use the Ethereal to catch
packets between the bearer network and RNC, and check whether packets exist
in the network. If packets are unavailable in the network, the source end does not
send packets. Then, check whether the problem results from the RNC side or
non-RNC side.
This principle applies to the location of a SCTP problem or other problems.
2. One-way connection due to incorrect configuration in the upper layer
The tracing is performed on site. The following figure shows trace results.
2008-09-14 华为机密,未经许可不得扩散 第 2 页, 共 139 页
IPRAN 开局指导书 内部公开
The peer end transmits the INIT. The local end returns INITACK. Both ends start
to interact with Cookie. Then, the RNC sends an ABORT. The peer end
continues to transmit the INIT. In the initial link establishment, the RNC transmits
the ABORT. The causes are as follows:
The data receiving and transmitting are normal. The processing of protocol
messages is abnormal, because the protocol is processed on the SPU. After the
start of the SPU, the system prints that the upper layer link is not configured.
Location principle
Check the following:
1. Interconnection parameters of the SCTP: Check whether the IP
address and port are consistent with the negotiation.
2. No configuration of the upper layer application of the SCTP: For
example, the NCP, CCP, and M3UA are not configured.
3. Connection failure due to the loss of Cookie packets
In a test, the signaling interaction is as follows (results traced at the RNC side):
According to the signaling tracing, the NodeB correctly sends the INIT and the
RNC also correctly returns the INITACK. The NodeB does not send COOKIE.
The causes are as follows: Use the Ethereal to catch packets. Packets exist in
the network. At the NodeB side, the symptom is as follows:
2008-09-14 华为机密,未经许可不得扩散 第 3 页, 共 139 页
IPRAN 开局指导书 内部公开
According to the tracing on the SPU, the packet does not reach the SPU. The
packet may be lost in the PIU.
The INIT and INITACK packets can be received and transmitted normally. It
indicates that the channel is normal.
The INIT packets can be received. The RNC cannot receive COOKIE packets.
The comparison of two packets (including quintuple, VLAN, and IP header)
indicates that no error is found. The COOKIE packet is longer than the INIT
packet. Check the MTU and find that it is too small. The PIU loses the MTU. Run
SET ETHPORT to set the MTU to a larger value. The problem is solved.
4. Location of faults related to the SCTP
Handlings of a problem that does not comply with the protocol:
1. Analyze the tracing on the SPU. Analyze whether each field of each
protocol message is correct.
2. Start the redirection of the SPU serial port and analyze the printing
information on the SPU.
3. Locate the problem on the SPU according to the information
corresponding to the serial port redirection.
Note: Usually, this type of problem results from incorrect configurations. Hence,
engineers should check configurations.

9.1.3 Cases of M3UA Common Problems
1. The link establishment fails due to inconsistent configurations at both ends
Symptom:
One end of the link is DOWN and the other end is INACTIVE. The ASP end sends UP
messages to the SGP periodically.
Handling:
1. Analyze codes. When configuration at both ends are inconsistent, the
SGP returns the ACK after the receive of the UP message, with
carrying the error information in the Info field. After receiving of the
ACK, the ASP discards the message, without any processing. After the
timeout of the UP timer, the ASP sends the UP message again.
2. Analyze configuration data. It is found that the configurations of the
OPC and DPC at both ends are not matched. This is the cause.
Comments:
In the case of the data configuration, engineers should ensure the correctness of the
data. The data check mechanism is available in the M3UA, and the mechanism cannot
check the configuration of the peer end. In the case of the data configuration, engineers
should check configuration data at the peer end.
2. A link fails to be established due to the repeated configuration of the ASPID
Symptom:
At the ASP side, one link is configured. ASP ID is 65536. During the link establishment,
it is found that the SGP side returns Error (ASP illegal flag). The link fails to be
established.
Handling:
1. Analyze the codes. During the link establishment, the system judges
whether the link with the ID is recorded in the linkset when the UP
message is received. If yes, it indicates that the link is established and
the system returns Error. The link is not established.
2. After the communications with the product line, it is found that the link is
added in the case of the online operations. The product personnel do
not know whether the ID in the previous links exists. Engineers guess
that the possibility is high.
3. After the replacement of the ASP ID, the problem is solved.

Comments:
When data is dynamically added, engineers should familiar with the previous
configurations to avoid the conflict between the new data and old data.
