Web 2.0 and new multimedia content will drive ever-growing bandwidth demand


Networks are changing as the world goes mobile with data

Traditional core networks are increasingly complex and the platforms will be totally inadequate and too expensive to meet future capacity and service

delivery challenges

• Cell sites get smaller/more numerous • Heterogeneous access networks will exist for some time• Flat, end-to-end IP as unpredictability of data requires fast adaptation are shaping tomorrow’s wireless networksToday’s mobile end-users’ behaviors…

Customer challenge and opportunity2


Data traffic exponential growth from increasing demand for data services ― music downloading, web browsing, video streaming, which demand higher data rates, capacity and better network performance.

Disconnect between traffic and revenues putting pressure on operators margin. Increasing focus on lower cost per bit. Scissor effect drives the need for network transformation solutions that cope with the data traffic/revenue challenge. Social and technology trends are leading to a mobile traffic explosion that will continue in the next year. Video and content-rich services are key for growth. New value chain emerges with ACPs to monetize the network assets.Depending on their business plans, operators will deploy different strategies to interwork existing 2G/3G networks with LTE to provide seamless mobility and service continuity at reduced costs.

MME Capacity: High performance, scalable, room to grow

MIF supports up to 325k msgs/sec. Includes IPsec support Connectivity to 6K eNBs Switch blade (Hub)can support additional MIF (for future growth)

MAF Capacity is >36k msgs/sec. per MAF, (325k system total) assumes 70% CPU occupancy, 20% processing of NAS messages 300 byte message size, average 5 msec latency (to process a procedural message)

Room to grow ATCAv2 slots and fan system support for 300W boards Call engine process entirely for a user ran on a single processor => capacity scales with the number of core in

the MAF board

MME paging

The MME provides the service provider with the flexibility to provision a

paging strategy that controls aspects of paging such as: Maximum number of paging attempts (up to 4 attempts)

Paging method used for each page attempt

T3413 timer interval (interval to wait for page response) used for each page attempt

The following paging methods will initially be supported by the MME: Page only at the last seen eNodeB

Page in all eNodeBs for last seen Tracking Area

Page in all eNodeBs for last seen Tracking Area plus all eNodeBs for the neighboring TAs of the last seen Tracking Area

Functionality to measure effectiveness of paging Overall effectiveness of Paging

Effectiveness of Paging by page attempt

Effectiveness of Tracking Area Update procedure

Percentage of time UE found in last seen TA (from PCMD)


Per Call/Connection Measurement Data ― PCMD collection

PCMD is a real-time diagnostics and troubleshooting tool that provides records for call/connection information, for example, call duration, quality and call disposition, and other important call events occurred during the call, such as call setup, call failure, handover and call termination Each PCMD record is created on

per call/connection basis PCMD also provides user

throughput related information so the operators can leverage the data to evaluate subscriber experience

The PCMD function is complementary to service measurements ― more UE experience focused

Examples show a) connection attempts over time sorted by device type

b) single user ping-ponging between two cells

Packet data interworking options

UE-based “drop & reselect”

R8 LTE interworking with pre-R8

GPRS/WCDMA core

All-R8 approach to Interworking

- Simplest option- IP address is re-established and hence session

continuity is broken

- Based on TS 23.401 Annex D- Uses pre-R8 interfaces (Gn/Gp) as basis for

interworking- P-GW is the mobility anchor for I-RAT- HO gap < 1 sec

- Based on TS 23.401 main text- Uses R8 interfaces (S3/S4) on legacy SGSNs as basis

for interworking- S-GW is the mobility anchor for I-RAT- HO gap < 500 ms


Separate LTE and 3GPP 2G/3G networks with UE-based drop-and-reselect

Simple overlay: when UE detects a better network, it drops the current network and reselects the better one

Each network has its own IP@ plans Loss of IP@ implies no session continuity (VPNs will drop)

Interworking between S6a and Gr+ interface under definition at 3GPP CT4 to interoperate with legacy HLR/HSS in roaming case

The P-GW is required to be a GGSN and a legacy GGSN remains in place for non-LTE capable mobiles

All-R8 approach

Technically, mobility across 2G/3G and LTE is supported

Requires upgrades to 2G and 3G SGSNs, to RNCs, and possibly to Circuit Core (not shown) to support IP Iu-CS

Signaling between MME and SGSN is via S3 and between SGSN and S-GW via S4

Bearer uses either S4 or S12 (Direct Tunnel) via S-GW

Combined HSS and HLR with a new diameter S6a/S6d interface. R8 features:

EPC bearers instead of PDP Contexts; QCI instead of QoS profile; Default Bearer

Buffering of DL packet in idle mode in S-GW rather than in SGSN

Idle-mode signaling reduction for an R8 UE Note a legacy GGSN can remain in place to support

non-R8 mobiles

Evolution to full R8 EPC

Full R8 EPC

S-GW as the anchor for intra-3GPP mobility

Intra-3GPP HOs are modeled on S1-based HO

Idle-mode Signaling Reduction (ISR) benefit possible (paging can be initiated from S-GW)

The proposed approach

Introduce LTE based on Gn/Gp I-RAT interworking

– Keeps 2G/3G network stable during the LTE introduction period

– Data cards are not particularly mobile so impact of incremental idle-mode signaling is not huge

Deploy Full R8 when ready

Assumptions on mobility and subscriber use pattern shall be tracked by careful monitoring and trend analysis of idle-mode signaling load ― expected to be initially low for data cards

Problem: Registration “ping-ponging” can generate excess signaling traffic in the network (see below)

RAU if no ISR orISR with expiredperiodic timer

Update only ifperiodic timerexpires

Solution: ISR allows UEs to dual-register but now paging in both networks is required (only possible in R8)

Industry analysts comment on Alcatel-Lucent 9471 MME

“Alcatel-Lucent has a head start over Ericsson AB and Nokia Siemens Networks in its understanding, expertise and deployment references for IP networks. If Alcatel-Lucent can be fully competitive on the radio side of the LTE networks equation, then with its IP pedigree the company has a very real chance to go toe-to-toe with the big wireless vendors in LTE.”

Patrick Donegan - Senior Analyst at Heavy Reading

“The fact that you’re splitting out the control and bearer planes makes their platform choices logical. It mirrors the split in the architecture.”

“We believe Alcatel-Lucent has a viable product strategy and will gain market share in the packet core as operators migrate to LTE and converged 2G/3G/LTE cores.” Gabriel Brown – Senior Analyst with Heavy Reading
