Ater a slow start mobile data has nally taken o. Many actors, technical and non-technical,
relating to the success o mobile data have come together to provide data services that are
both easy to use and meets the users perormance expectations.
Network and handset capability have met with content and billing regimes and along with
growing consumer condence and experience this is leading to increased use o data services
provided by operators. As consumers, operators and third party application providers gain
more experience with data services beyond the plain WAP home page, the demand or data
is orecast to continue growing or the oreseeable uture. Good news or operators who are
generally seeing a reduction in revenues rom traditional voice based services. Revenues in
the next decade will depend on increasing eciency and nding alternative non-voice services.
The graph opposite shows the increase in use o both xed and mobile broadband services,
it also shows that the use o mobile broadband is set to overtake xed broadband in the uture,
this will only be possible i we can deliver a high perormance and consistent service that the
subscribers will come to expect.

LTE E-uTran objeties
LTE is ocusing on optimum support o Packet Switched (PS) Services. Main requirements
or the design o an LTE system are outlined in 3GPP TR 25.913 (2006) and can be summarised
as ollows:
dt rte: Peak data rates target 100 Mbps (downlink) and 50 Mbps (uplink) or 20 MHz
spectrum allocation, assuming 2 receive antennas and 1 transmit antenna at the terminal.
Tgpt: Target or downlink average user throughput per MHz is 3-4 times better than
release 6. Target or uplink average user throughput per MHz is 2-3 times better than release 6.
(release 6 – HSPA)
Spetm Efiey: Downlink target is 3-4 times better than release 6. Uplink target is 2-3
times better than release 6.
Ltey: The one-way transit time between a packet being available at the IP layer in either
the UE or radio access network and the availability o this packet at IP layer in the radio access
network/UE is less than 5 ms. Also C-plane latency is reduced, e.g. to allow ast transition
times o less than 100 ms rom camped state to active state.
Bit: Scaleable bandwidths o 5, 10, 15, 20 MHz are supported. Also bandwidths
smaller than 5 MHz are supported or more fexibility, i.e. 1.4 MHz and 3 MHz or FDD mode.
Itekig: Interworking with existing UTRAN/GERAN systems and non-3GPP systems is
ensured. Multimode terminals support handover to and rom UTRAN and GERAN as well as
inter-RAT measurements. Interruption time or handover between E-UTRAN and UTRAN/GERAN
is less than 300 ms or real time services and less than 500 ms or non real time services.
Mltimei Bst Mltist Seies (MBMS): MBMS is urther enhanced and is then
reerred to as E-MBMS.
Mbility: The system is optimized or low mobile speed (0-15 km/h), but higher mobile speeds
are supported as well including high speed train environment as special case.
Spetm llti: Operation in paired (Frequency Division Duplex / FDD mode) and
unpaired spectrum (Time Division Duplex / TDD mode).
c-existee: Co-existence in the same geographical area and co-location with GERAN/UTRAN. Also, co-existence between operators in adjacent bands as well as cross-border coexistence.
Qlity Seie: End-to-end Quality o Service (QoS) is supported.

System aitete Elti (SaE)
One o the main objectives o the LTE architecture is an overall simplication o the network with
a reduction in the number o nodes required in the radio access and core network components.
The evolution o the network is designed to optimise perormance and improve cost eciency.
Also interoperability with the existing 3.5G inrastructure is important, particularly mobility and
handover between the networks.
The Evolved Packet System (EPS) is divided in to radio access and core network.

Ele uMTS ri aess netk (E-uTran)
Evolved UMTS Radio Access Network (E-UTRAN) contains a single element known as the
Evolved Node Bs (eNB). The eNB supports all the user plane and control plane protocols to
enable communication with the UE. It also supports radio resource management, admission
control, scheduling, uplink QoS enorcement, cell broadcast, encryption and compression/
decompression o user data.
The eNB is connected to the core network on the S1 interace. The S1 interace allows the
eNB to communicate with the Mobility Management Entity (MME) via the S1-MME interace
and the Serving Gateway (SGW) via the S1-U interace. The interaces support a many to
many relationship between eNB and SGW/MME.
The eNB are also networked together using the X2 interace. The X2 interace is based on
the same set o protocols as the S1 and is primarily in place to allow user plane tunnelling
o packets during handover to minimise packet loss.

Ele Pket ce (EPc)
The Evolved Packet Core contains two principle unctions, high speed packet handling and
mobility management, these unctions are carried out by the SGW and MME. This separation
o unction allows each to be implemented on a platorm optimised or data handling or
message processing. This will result in more optimised perormance and allows independent
scaling o each component and ecient topological optimisation o platorms to ensure
consistent service i.e. reduced latencies and maximised throughput.
Seig Gtey (SGw)
The SGW acts as a router, routing and orwarding packets o user data, it is able to provide
transport level packet marking, and the marking process may be used or QoS management
by other network elements. Also some accounting unctions or UL/DL services.
The SGW will act as a local anchoring point or inter eNB handover and can also act as a
3GPP anchoring point or handovers between UMTS and LTE. It provides idle mode unctions
such as packet buering and initiation o network triggered service request.
The SGW is also one o the Lawul Interception points in the network.
Mbility Mgemet Etity (MME)
The Mobility management entity (MME) is the primary signalling node in the EPC, NAS signalling
is terminated at this point and included signalling related to bearer establishment and
authentication o the UEs through interaction with the Home Subscriber Server (HSS). It is also
the decision point or SGW selection, and MME, SGW selection during handover where EPCnode change is necessary.
The MME handles roaming unctions such as allocation o temporary identities, admission
control and communication with the home HSS on the S6a interace.
Pket dt netk Gtey (P-Gw)
The P-GW is the entry and exit point or UE connectivity with external data networks. It provides
unctions o packet ltering, via deep packet inspection, allocation o UE IP addresses, downlink
packet marking, and service level charging, gating and rate enorcement.
The P-GW also acts as an anchor or mobility between 3GPP and non-3GPP technologies such
as 3GPP2 CDMA2000 and WiMAX.

Roaming is supported by the SAE, the gure opposite show the situation where a user is
roamed on to a V-PLMN (Visitor – PLMN). A roaming agreement must exist between the
home and visited systems. The pictured scenario may be when the user visits a dierent
country or where national roaming is supported.
Part o the connection is handled by the visited network, this includes the radio access,
mobility management and elements o session management. U-plane data is routed via
visited SGW to the home network P-GW and the S8 interace.
The S8 interace carries both user plane data and control signaling and is based on the
Gp interace rst dened in the GPRS/UMTS core network specications.
The S6 interace connects the MME to the HSS and handles session and mobility related
signaling including security.
The data sessions are managed locally by the visited network but the call is anchored in
the home network, allowing the home operator to maintain control o the session. This may
not be the most ecient routing in terms o cost and system resources, thereore, there is
an option to route the U-plane trac to a P-GW in the V-PLMN and make connections, or
example, directly to the internet or local services.

n-3GPP aess
The diagram opposite shows the architecture that allows IP access to the EPC using non-3GPP
access technologies, i.e. Wireless LAN (802.11a,b,g,) WiMAX. There are two possible access
scenarios, both o which appear on the diagram, trusted and non-trusted access.
Where the operator owns and operates the WLAN network, this may be considered a trusted
case, the user data rom the WLAN network may be sent directly to the P-GW via the IP based
S2 interace. Inormation relating to subscriber proles, authentication vectors, network identity,
charging and QoS inormation may all be provided to the WLAN access via the Ta interace.
The inormation is provided via the 3GPP AAA server which acts as an inter-working point
between the 3GPP and IETF worlds. The main purpose o the 3GPP AAA server is to allow
end to end interaction, such as authentications to take place using 3GPP credentials stored
in the HSS via the Wx interace.
In the non-trusted case, e.g. a corporate entity has its own WLAN network and would like to
oer 3GPP access to its customers, there are additional network elements to maintain the
inrastructure security and integrity. The ePDG (evolved Packet Data Gateway) element carried
all the trac rom the WLAN via a secure tunnel (IPSec) over the Wn interace. The Wm interace
allows the user related data rom the HSS via the 3GPP AAA Server, to be exchanged, ensuring
proper tunneling and encryption between the user terminal and the P-GW.
In both o these cases the MME and SGW are redundant.

Where 2G/3G cells are adjacent or overlaid on to E-UTRAN cells there will be a requirement
or interworking between the dierent inrastructures to support inter-system mobility. No new
systems elements are required but 2 additional interaces are specied, S3 and S4.
S3 supports the user and bearer inormation exchange between the SGSN and the MME during
handover/cell reselection. QoS and user context will be exchange so the target system has all
the inormation required to re-establish the bearers on the new cell. S3 is based on the IP Gn
interace designed or 2G/3G core architecture.
S4 carries the user plane data between the SGSN and the SGW. The SGW play the role o
the mobility anchor in inter-system exchanges, it has a very similar role to the GGSN in 2G/3G
networks. The S4 interace is also based on the Gn interace.

LTE Femt cells
Currently, 3G emto access points, which are the WLAN-like devices residing at customer
premises, are connected to so-called emto gateways via the customers’ private DSL links
using largely proprietary protocols to provide emto-specic unctionalities such as plug
and play, sel-organising eatures, guest user management, roaming or charging. The emto
gateway, which can connect to thousands o emto access points, translates the emto
communication links to the “Iu” interace, which is the standard connection between a 3G
core and a 3G access network.
In order to resolve resulting compatibility and interworking issues, 3GPP, the standardisation
body behind the GSM amily o technologies, has nominated this issue as a study item in the
upcoming version o its standard, 3GPP Release 8.
Release 8 is also the rst version o the 3GPP standard that contains the long awaited ourth-
generation (4G) GSM variant LTE (Long-Term Evolution). Femto aspects in this study cover both
3G (UMTS) and 4G (LTE) inrastructures. 3GPP Release 8 describes the emto architecture in
an ocial standard document or the rst time. It introduces the concept o home base stations
or 3G and 4G using the nomenclature Home Node B (HNB) and Home eNodeB (HeNB).
Additionally, it denes a new interace capable o directly connecting home base stations to
3G and 4G core networks, the ‘IuH’ interace.
According to the 3GPP specication, all home base stations in the uture will have to provide
the ollowing unctionality:
HNB and HeNB deployed as small UTRA and EUTRAN cells, respectively, in domestic,•
small oce and similar environments.
The HNB and HeNB interconnects with the 3G core and Evolved Packet Core, respectively,•
over a xed broadband access network (e.g. DSL, cable, etc.).
Support or ull mobility into and out o a HeNB coverage including service continuity where•
applicable.
Operators and owners o HeNB and HNB will be able to control access to the resources•
provided.
The ull specication or HNBs, HeNBs and IuH will become available with Release 9 o the
3GPP standard.

The objective o the Sel-Conguration SON unctionality is to reduce the amount o human
intervention in the overall installation process by providing “plug and play” unctionality in the
eNodeBs. The scope o sel-conguration unctionality is expected to expand and evolve with
upcoming versions o the LTE standard.
Sel-Conguration o eNodeBs will reduce the amount o manual processes involved in the
planning, integration and conguration o new eNodeBs. This will result in a aster network
deployment and reduced costs or the operator in addition to a more integral inventory
management system that is less prone to human error.
Sel-Conguration is a broad concept which involves several distinct unctions that are covered
through specic SON eatures, such as Automatic Sotware Management, Sel Test and
Automatic Neighbour Relation conguration.

Spetm reqiemets LTE
It is very apparent rom many industry sources that the mobile broadband revolution has
begun, in the next ew years there will be an ever increasing demand or access to high speed
broadband data services. Technologies like LTE and WiMAX seem very well placed to be able
to oer these services to subscribers in a very cost eective way.
One o the greatest problems to overcome will be availability o spectrum and the availability
o spectrum in suitable bands. There is a great deal o work currently taking place to ensure
that operators have access to a sucient amount o spectrum to solve the principle problems
o coverage and capacity that they ace right now and may potentially ace to a greater extent
in the uture.
The ITU-R already recognises the coming issues and has begun to address the problem
at WRC 07 and will make urther resolutions at WRC11.

Under Agenda Item 1.4 “to consider requency-related matters or the uture development
o IMT-2000 and systems beyond IMT-2000.
“WRC-07 has identied globally harmonised spectrum or use by International Mobile
Telecommunications (IMT-2000 and IMT-Advanced)”.
Additional spectrum was allocated or IMT systems in various new bands, resulting in
392 MHz o new spectrum in total in Europe and 428 MHz in the Americas:
20 MHz in the band 450−470 MHz (globally)•
72 MHz in the band 790−862 MHz or Region 1 (Europe) and parts o Region 3 (Asia)•
108 MHz in the band 698−806 MHz or Region 2 (Americas) and some countries o •
Region 3 (Asia)
100 MHz in the band 2.3−2.4 GHz (globally)•
200 MHz in the band 3.4−3.6 GHz (no global allocation, but identied in 82 countries)•
Note: These bands will not be available immediately or NGMN usage, but opened to the market
ollowing transition periods o up to several years. Additionally, the allocations regarding the
bands 790-862 MHz and 3.4 – 3.6 GHz in Region 1 will only come into ull eect in 2015 and
2010 respectively.

The table opposite shows the existing bands supported by 3GPP and 3GPP2. The majority
o these are already in use with the well known 2G/3G technologies. One o the largest areas
o interest or operators and regulators alike is the potential or spectrum re-arming in these
bands. Spectrum neutrality is becoming increasing wide spread, where the regulator lits the
technology specic nature o the licenses.
UMTS900 has already been approved and there is work taking place on the USA in the
700MHz band. The digital dividend is also another area o interest, analogue TV broadcast
are coming to an end in many parts o the word leaving behind spectrum in the ranges
470 – 862 MHz.
