The evolution from old world to a new world network architecture has been a work in progress since the last decade at TM.
TM’s recent transformation of it’s network architecture has been the result of a 4 year plan.
TM is currently migrating IP bearer network from ATM to MPLS, from legacy OSS/BSS to consolidated OSS/BSS with SDP and from PSTN to NGN.
Evolution is not an option, but a way of life for TM to maintain it’s leading position as the nation’s tier-1 carrier.
Beginning this year, TM decided the direction for us in moving forward is IMS. Hence, instead of the Soft switch we adopted a network design comprising both AGCF and Soft Switch.
In the years ahead, and God willing, we shall further evolve the architecture to an IMS centric AGCF model.
TM’s CDMA network is distributed over three areas: Peninsular, Sabah and Sarawak.
The core network is supplied by Huawei (TDM C6) MSC switch, radio access network is supplied by Motorola and Huawei respectively.
Mobile VoBB maturity and readiness of IMS Handsets are the key factors affecting the CDMA Evolution Plan.

Scrap Notes
Being a ‘late’ adopter of IMS, we are in the position to reap the benefits of developed standards.
Required update to the blueprint.
TM’s long term NGN architecture serves both new and legacy services.
Migration planning is in progress in the
POTS (PSTN and IMS AGCF)
VoBB (FTTx, MSAN)
xDSL (ATM to Access Gateway and IP MSAN)
The existing legacy network and new IMS network is expected to co-exist for 6-8 years until migration completes.
TM’s new services is shifting towards IP Centrex and Messaging with support for Legal Intercept and Emergency Services and <future> integration with Mobile Network (CDMA).
// need to find out quantity of DLS and DTS to be migrated // e.g. 500 nodes nationwide ?

8. IPv6 Deployment Stages
IPv6 deployment approach of TM NGN highly depends on the IPv6 readiness of terminals of end-users.

As the major telecommunication service provider TM plays an important role to ensure successful transition from existing IPv4 network towards the future IPv6 network and hence fully aligns with the IPv6 Deployment Plan as defined by the Malaysian Regulator – MCMC.
Based on the latest IPv6 Deployment Plan updated by MCMC, the deployed network shall be IPv6 ready by year 2010.
We expect 3 stages of Deployment:
By 2010, the deployment of IPv6 is in stage 1 where most of the IPv6 networks are islands compared to IPv4 networks.
At this stage, the majority of the CPEs and networks are still based on IPv4.
By 2013, with the aggressive allocation of IPv6 addresses and exponential growth rate of Broadband customers based on IPv6, then the overall IPv6 deployment will be in Stage 2.
In Stage 2, IPv6 and IPv4 networks are equivalent in number.
By 2015, the IPv6 deployment will ascend into Stage 3 where IPv4 networks are considered as an island compared to the dominant size of IPv6 networks.
Two concerns:
IPv6 deployment approach of TM NGN highly depends on the IPv6 readiness of terminals of end-users.
Assumption is based on exhaustion of IPv4 addresses by Y2011 and exponential growth rate of IPv6 CPE terminals being deployed for future broadband services.
IPv6 rate of adoption impacted by global slowdown a valid cause of concern ?

9. Service Plans Part 1: Service enhancement via IMS
Part 2: Existing service
inheritance, integration
& multimedia services via IMS
IMS based Voice
Existing Service Node integration
// Voice revenue in Malaysia market is still exhibiting growth, but the growth only comes from mobile, whereas mobile voice dominated 74% of market share by the end of 2007.
// Although TM holds a sizeable piece of the total voice market, TM relinquished its market share to Maxis in Declining market share also indicates increasingly aggressive fixed mobile substitution in the market.
// Mobile penetration has reached 93.9% as at Q3’ The slowdown of growth in subscriber number and falling ARPU points towards saturation in mobile voice market.
TM as the market leader in broadband with a strong year-on-year customer growth of 32% to 1.6 million in Q3 2008, has unveiled plans to bring High-Speed Broadband also known as “HSBB” to every household in Malaysia’s major urban areas over a 10-year period.
For the immediate term, TM’s service plan comprises 2 parts:
Part 1:
Bundling carrier class Voice with High Speed Broadband will offer TM’s customers a wider choice and a richer experience.
VoBB allows users to make and receive calls over a broadband connection. One can enjoy the service by using a broadband-enabled fixed phone or PC/laptop. VoBB provides basic Voice Services as well as Supplementary Services, such as Call Transfer, Call Forward, Call Waiting, Outgoing Call Barring etc. Other value added are offered on top of basic services including ring back tone, SMS, Multi-number one line
VoIP services had experienced a strong growth in However, it is a lackluster year for most of the ASPs as the market dynamics had turn to the favor of the incumbent carrier, TM. This is owing to TM’s resolute focus on conquering the VoIP market towards the end of 2005.
TM’s dominance in both VoIP and broadband space (1.4 million subscribers or 85% market share in Q2 2008) enables TM to position themselves as a strong player in VoBB. TM has the advantage of leveraging on its existing base to cross sell VoBB via broadband bundling.
Part 2:
Traditional IN services will be triggered in the NGN platform through the gateway with the TELLIN System. Advanced IN services will migrate to TELLIN Application Server (AS). The TELLIN application server connects to the C5 Softswitch through SIP. Just as AIN TELLIN will serve domestic and international subscribers.

IMS E2E QoS control architecture is divided into three layers comprising:
Service Control Layer
Bearer Control Layer
Transport Bearer Layer
The CSCF implemented (which is responsible for call session control) sends the QoS control request to the entities in bearer layer during establishment of call session.
SPDF&A-RACF are responsible for QoS policy decision and management of bearer and access Network resources.
// The NASS now shown in this diagram acts as DHCP server and storage of location information derived from Option82.
The layer involves BGF (implemented by SBC), IP Bearer, aggregation/access Network (MetroE).
// In Huawei IMS QoS architecture, BGF provides the policy enforcement functionality according to the QoS policy received from RACS.
// RACS comprises A-RACF and SPDF

Scrap Notes
The Access Gateway (AG) tags VLAN, 802.1p and DSCP for different traffic from terminals, including voice, signaling.
The Metro E Provider Edge (EPE) tags MPLS EXP for different traffic profiles from Access Gateway to the EPE based on VLAN or 802.1P, and then sends the traffic into the Metro-E. The Metro-E guarantees the QoS based on MPLS EXP.
The SBC in the IMS edge tags DSCP for voice, media and signaling.
The A-RACF & SPDF/PDF/PCRF functionalities accomplishes service/session based QoS control by enforcing QoS policy according to service, subscriber and subscription type.
