FMC Market Development
It is a long-term process to deploy FMC network and services
In some competitive telecom markets, a few telecom operators have
deployed simple FMC services such as Fixed-Mobile service bundling,
Tariff Bundling, Converged marketing strategy even converged BOSS
But most of telecom operator, they are still ongoing to research what’s IMS,
how to converge fixed and mobile network and service platform.
The ideal FMC architecture should be based on all IP, supporting converged
network, converged services, converged corporation organization support,
multi-mode terminal, and more flexible business model.
Synergy among heterogeneous networks is the emphasis and key opportunity
at the early stage of FMC

Relationship between IMS and FMC
 FMC≠ IMS ；
 IMS can be deployed as convergent core network to provide convergent session control
and service control, IMS is a component of FMC
 FMC can be deployed gradually, even IMS is immature
 Based on IMS, operator can provide convergent service experience
 Convergent Service Platform, convergent Bearer Network, and convergent BOSS are the key
factors to reduce CAPEX/OPEX

What is IMS?
IMS ：IP Multimedia Subsystem (3GPP TS 23.002)
The IM subsystem comprises all CN elements for provision of IP multimedia services
comprising audio, video, text, chat, etc. and a combination of them delivered over the PS
domain.
The entities related to IMS are CSCF, MGCF, MRF, etc. as defined in the stage 2 of the IM
subsystem TS 23.228 [34]. See TS 22.228 [27] for some service examples of IMS.
IP = IP based transport
IP based session control
IP based applications
Multimedia = More than voice only, including video, text, and mixture of them
Subsystem = overlap the existing PS system

best technology choice to initial IMS
Step 2 (2010 – beyond): ALL IP become mature (CS service to be replaced by IMS AS)

Relationship between Soft Switch and IMS
IMS is the best core network architecture for future
- New revenue generation by offering abundant MM services
- Open Network architecture, Access network independence
 Sharing and long-term co-existing of Soft Switch and IMS
- Soft Switch is mature & best solution for voice service experience continuity
- Share of the IP backbone with Soft Switch network
- Share of technologies and experience in terms of IP QoS, IP security,
high availability and large-scale IP network operation
- Share of the converged service platform
 Soft Switch will evolve to the architecture of IMS
-Soft Switch evolves (software upgrading) to MGCF, AGCF
- MGW evolves (software upgrading) to IM-MGW

How to deploy IMS?
Stage 1- introduce non-real-time multimedia
VAS, supplement for R4 CS domain.
Stage 2- introduce real-time multimedia service
,such as VoIP and Video over IP in IMS and
support inter-working with CS and PSTN
Stage 3- the target ALL-IP network

Considerations for IMS deployment
 Key technology and consideration for IMS deployment
- Core network evolution (soft switch evolution to IMS)
- Inter-working capability of IMS to legacy network
- CSI (Combining Circuit-Switch and IMS) service offering
- IMS based VCC (Voice Call Continuity)
- IPV4 & IPV6 inter-connection
- End to End QoS
- IP Security
- IMS Service Charging
- Commercial and diversified IMS terminals

IMS Industry Status
 Standardization
 IMS will be the unified core network for both fixed network and mobile network in the future,
which is the agreement of primary standard organizations.
 3GPP has a deeply research for IMS, in mobile domain, IMS architecture is basically mature,
on detail, the research is going on.
 In fixed domain, ETSI TISPAN has a deeper research for IMS, the NGN framework based on
IMS is finalized, but the detailed requirement and technical research is still in progress. ITU
NGN FG now is still in the first phase for IMS.
 Operator attitude and deployment
 IMS is in focus by European telecom operator, and deploying trial IMS in quick succession
 Commercial restriction on shortage IMS terminal and innovative IMS services
 Almost no commercial deployment and still no successful business model

Conclusion
•
Telecom industry is confronted with structural changes and cross industries
convergence (telecom, IT, Media, Computer, etc…), driven by Mobility and New
wave of internet (like MSN, Skype, …)
•
Fixed and Mobile Networks Convergence (FMC) is the basis of the new Converged
Industry.
•
FMC will allow the end user to seamlessly enjoy different services (including video
services) any time, any place, with any terminal and with one bill.
•
For the operator, FMC is realized in 3 planes: network, operation and services.
•
IMS is a keystone in realizing FMC and has been the choice of many standard
bodies such as 3GPP, TISPAN, IETF,…
•
Softswitch is a considerable step towards IMS deployment, and can migrate to be
part of the IMS network.
•
IMS deployment will go through different stages where IMS and Softswitch will
coexist for quite a long time.
•
Huawei is actively participating in the standardization of IMS through different
standard bodies, and has deployed many IMS trials worldwide.
