Telecom services and networks will undergo structural changes in the next five years and the possible roadmap is shown in the following figure:

The goal of many operators will be to achieve All IP architecture by 2010. The following is a list of key migration directions:

1. FMC: In the future architecture, only access networks will be different, while the rest will remain the same. IMS will serve as the core of FMC and although softswitch and IMS will coexist for a long time, softswitch will ultimately become a part of IMS as AGCF or MGCF. Huawei's IMS has the ability to support fixed and mobile convergence.
   
   
2. Unified User database: Different kinds of user data such as AAA, HSS, HLR, and IPTV will be managed through a unified database. The foundation of FMC can provide a more user-friendly experience, such as featuring one ID, one billing, and one time authentication. Huawei's SHLR will provide operators with the capability to manage all user data.
   
   
3. Unified transport network: It is inevitable that the packet-oriented transport network will replace the TDM-oriented transport network. Carrier Ethernet, NG-WDM and IP+Optical will become key technologies. With its extensive range of products, Huawei has the ability to provide end-to-end solutions of next-generation transport platform.
   
   
4. Unified service platform: Many operators today have several service platforms including IN, portal, SMS, MMS, and IPTV, which requires more complex operation, resulting in high cost, and bad user experience. The integration of service platforms is necessary and SDP will play a key role in the integration process. Huawei's ENIP will also be able to provide a common platform for all kinds of applications.

In general, the telecoms industry is entering a new era, one in which the structural changes of services and networks is inevitable. Operators must find their strategic position in the new value chain and take on a new service direction. In addition, to support their strategic transformation, they must build new networks driven by the need for new services.
