i The OMM is a necessary part of the NE.



ii The OMM manage network elements in the TMN. In addition to configuration management, performance management, fault management and security management required by the TMN, the OMM also provides topology management, system management, and tools, to maximally facilitate local operation and maintenance. Each OMM manages one network element.

iii As the man-machine interface of the OMM, the local management terminal (LMT) can be placed locally, or act as remote management terminal (RMT) to perform remote operation and maintenance through E1, X.25, DDN or common dial-up mode.

iv The OMM adopts the internal interface to communicate with the NE, and Qx interface to communicate with the NMC.

v The OMM layer can manage a variety of NEs such as MSC/VLR, HLR/AUC, BSS, PDSN, AAA, MSCe, MGW, etc.

NMC

i In addition to the OMM function, the NMC supports the CDMA Network Optimization (CNO2) that can manage, monitor, as well as make statistics and analysis of NEs in a centralized manner.

ii Each NMC can manage multiple OMMs, and through the cascade, one upper-level NMC can manage multiple lower-level NMCs.

iii The NMC adopts the Qx interface to communication with the OMM, and the TCP/IP, E1/T1, SDH, X.25 and DDN to connect to the OMM.

NBI (Northbound Interfaces)

i The CDMA OMC can be connected to the upper-level NMS via the standard CORBA, SNMP, and FTP.

ii CORBA and FTP interfaces support data report on performance management, alarm management, and configuration management, while SNMP interfaces provide realtime alarm report.

ii The server usually adopts HP, DELL and IBM rack-mounted PC server, or SUN Solaris server.

iii The CDMA OMC operating system and database platform is Windows + SQL, or Solaris + Oracle.

Hardware Reliability

i The CDMA OMC adopts advanced reliability technology for its hardware structure. The important OMC servers use RAID technology to achieve hot backup of data and reliable running of the system, and to ensure integrity of system data.

In view of many processes/threads during software operation of the system, it is required the processor should have high concurrent performance and loading capability. Therefore, the system hardware adopts multiple processors to handle load balancing. Meanwhile, when a processing unit has any fault, other processors can ensure uninterrupted normal work.

The server power has redundancy backup, so when a power supply unit has any fault, other units can continue supporting normal work of the system and send out hardware alarms to the occurring faults (alarm indicator and sound indicator). Also, the server rack supports dual-power redundancy to ensure continuous operation of the server.

To ensure network security, prevent message storm and implement network isolation, the OMC system adopts a router for connection.



System software supports dual-host active/standby mode. In the event of the active server failure, network disconnection, or power off, the standby server can take over the software task in time and ensure service continuity and high availability.



4 Software Introduction

In terms of function, software structure of the NetNumen™ M3 (CDMA OMC) is divided into the work station function (WSF), management application function (MAF), element mediator function (EMF), platform support function (PSF), and NE foreground and background agent. It can access the upper-level integrated NMS (Network Management System) via CORBA, SNMP, and FTP, etc.

Many key modules of the CDMA OMC system adopt the load control design while its software design adopts the error tolerance design widely; besides data adopt distributed storage structure on a whole. All these ensure reliable operation of the system.

NE refers to a variety of managed network equipment including MSC/VLR, HLR/AUC, BSS, PDSN, AAA, MSCe, and MGW.

PSF

The CDMA OMC is based on the platform structure. A mature network management platform can be constructed to implement 70% of the OMC software function. Upon this platform, network management software for each product is developed to implement only 30% of the function at the application layer. The platform strategy ensures accumulation and reuse of technologies and experience, as well as fast practicability and stability of products.



EMF

The EMF is responsible for information conversion between the NE and the MAF. As the existing ZXC10 NE series offer different interfaces, it is necessary for the EMF to conduct information conversion between the foreground NE and the background OMM. The EMF is connected to the NE or the MAF via the internal interface. In order for different type of NEs to access the MAF for unified processing, the EMF adopts the NE-related protocols to conduct the conversion.

MAF

The MAF acts as a manager in the system management.

The MAF processes information related to NE management application. It supports and controls NE management function, which involves processing original data, generating value-added data such as data centralization, alarm modification, statistics and performance analysis, and responding to the received information. Also, the MAF supports WSF, which involves data acquisition and manipulation, activity activation and confirmation, as well as event and notice transfer.

GUI Client

The GUI client provides F and G interfaces defined in the TMN. On the one hand, the WSF module is connected with the server via the F interface to collect and send user operation commands, and on the other hand, it accurately resolves information sent from the server via the G interface and presents it in user-friendly GUI mode to the network management personnel.

There are many GUI clients at the same level of the OMC that can manage and monitor the background system simultaneously.

CLI Server

The CLI server supports Telnet access, completes conversion from the Telnet user command to the F interface, resolves information returned at the G interface, and presents it to the user.

CLI Client

The CLI client provides the user with Telnet access. The user can log onto the system to access system functions via any Telnet program. The system supports simultaneous operation of many CLI clients.

Northbound interface

Based on the 3GPP/3GPP2 standards, the CDMA OMC provides the upper-level network management center with a standard CORBA interface that makes it easy for the user to develop an integrated network management system at a higher level. The CORBA interface supports various management functions including alarm, performance and configuration. With these complete and powerful functions, an universal interface for multiple services can be achieved.

Also, the CDMA OMC provides other kinds of northbound interfaces to meet users’ requirements for diversified and professional NMC interconnection. Through the SNMP northbound interface, alarm information can be reported to the upper-level NMC, which is applicable for fast interconnection to most of high-level NMCs. The FTP interface is also used to interconnect other NMCs.



5 Functions and Services

The NetNumen™ M3 (CDMA OMC) has numerous O&M functions to fully satisfy users’ actual management demands. It provides not only maintenance functions in compliance with TMN specifications such as configuration management, fault management, security management and performance management, but also other functions such as topology management, system management, log management, operation tools and CDMA analysis system, etc. The rich O&M functions help the operation and maintenance personnel accurately know running state of network equipment, make it easy for them to adjust and monitor the equipment, and keep the equipment running in optimal condition.

Fault Management: The fault management helps the operation and maintenance

personnel know in time all abnormal running conditions in the CDMA network and

helps them to locate causes and positions, so that the user can find, handle and

solve the system faults as soon as possible and ensure normal running of the

network. Alarm correlation analysis helps eliminate redundant alarm information and

alarm storm, locate and eliminate fault causes.

Performance Management: The performance management is responsible for

monitoring and analyzing performance of the network and NEs. With various

performance data collected from the NEs, the OMC knows network running

conditions, provides the operation and maintenance personnel with detailed

information that can offer guidance to the planning and adjustment of the network

engineering and improve the network quality.

Configuration Management: The configuration management presents configurations

for all kinds of equipment resources and settings of important parameters in the

CDMA network, so that the user can know easily the configuration and usage of the

key network resources, make related statistics, improve management, and maximize

profits. Additionally, it also provides necessary reference data for performance

management and fault management.

Security Management: The security management can protect and prevent

unauthorized OMC users from accessing or destructing the OMC and its NE system,

and legal users from ultra vires action. It records all security operation information for

review and ensures legal use of the system.

Topology Management: The topology management provides a topology view for the

whole network. It provides key information management, including the geographic

location, alarm, and KPI.

Log Management: The log management completes management of all kinds of

system logs that records information about all events and operations in the system.

With the logs, the user can know whether the system runs normally or not, locate the

cause of the fault, and trace back and review important events.

OMC System Management: The system management is used to manage the CDMA

OMC itself. Through the system management, the user can better maintain the

CDMA OMC. In addition to monitoring the performance of the application server and

database server, the user can also provide common database management such as

database query, backup and recovery via the DBMS of the network management

system.



Report Management: With related reports, the user can know running state of the

system in a fast, intuitive and convenient manner, and evaluate the system

performance. When combined with the policy management, the report management

system provides timed report function, i.e., timed printing of the reports. The time for

printing and the report type can be set. The user can preview and print the reports,

and store them in EXECL, TEXT, HTML, or PDF files.

Tools Set: Through the man-machine interaction, the user can observe the NE

resources at the foreground. In order to manage dynamic resources and parameters

of the system, the user can make an in-depth analysis and adjust dynamically the

setting of NE parameters by means of various system tools such as signaling trace,

service observation and diagnosis. These tools provide technical means necessary

for system debugging, operation and management.

Northbound Interface: The northbound interface function provides standard CORBA

interface that acts as an agent responsible for access to the third-party NMS. The

OMC also provides standard SNMP, and FTP interfaces for simple and easy

management and interconnection.

Call Detail Tracing (CDT): The function of CDT can record the detail data created in

the process of mobile station calling, including the process of setting up, the calling

release and the hand off. It also supports the functions of data browse and analysis

in order to fast find out the problems of the calling. The development interface and

re-analysis function are provided by the software packet of the network optimization.

CDMA Network Optimization (CNO2): The integrated network optimatization system

can present in a centralized manner all information related to important indicators,

serious alarms and configurations of the whole network, so that the maintenance

personnel can be clear about operation conditions of the whole network. By using

various evaluation methods and mathematic models, it can analyze network running

quality, operation support, and network construction. It provides expert knowledge

base that can automatically locate certain network problems, analyze their causes,

and offer reference solutions. Moreover, it provides powerful functions such as pilot

planning and optimization, adjacent cell planning and optimization, integrated report,

association analysis, etc.

Different NEs require different management overheads. The concept of logic element (LE) is adopted in measuring management capability so as not to be confused with the NE. The relation between the NE and the LE is shown in the table below.

Table 2 Conversion of NE and LE

NE Number of LEs

BSS (BSC+BTS) Count the number of LEs at the radio side according to the number of carrier-sectors.

120 cells (carrier-sectors) = 1 LE, where, 1 BSC (not including BTSs) = 120 cells

Theoretically, the CDMA OMC itself set no limit to the maximum number of NEs to be controlled, but the restriction comes from the processing capability, data throughput, and network bandwidth allowed for the CDMA OMC server. The server with higher processing capability can be adopted to manage more NEs.

6.2 The Number of Concurrent Clients

For servers operating in various modes, the maximum number of concurrent clients

(including remote clients) supported by the system is listed in Table 3.

Table 3 The Maximum Number of Concurrent Clients

Server Configuration The Number of Concurrent Clients

Mode 1 40

Mode 2 80

Mode 3 120

Mode 4 200

6.3 Network Management Bandwidth

Between the client and the server (GUI mode): Average bandwidth < 256 Kbits/s

Between the NE and the OMM: As the NE and the OMM are usually located in the

same LAN, the 10Base-T Ethernet bandwidth is great enough to meet the

requirement.

Between the OMM and the NMC: The average OMM data bandwidth for

management of a single BSS NE is less than 256 Kbits/s,. When several OMM

transfer data to the NMC, the bandwidth required is calculated by 200Kbits/s ×

the number of OMM. If necessary, the bandwidth redundancy shall be

considered.
