Open-source VoIP technologies can be employed to setup VoIP platforms by deploying open-source software on x86 servers, which have many advantages such as low cost, flexibility and openness. The usage of open-source VoIP technologies in NGN service platform deployment helps to reduce carrier's investment, shorten service deployment cycle and improve the duplicability of service platform. In the paper, the architecture of NGN service platform deployed by open-source VoIP technologies is proposed based on comprehensive survey and detailed analysis. A typical example is also provided to evaluate the feasibility and advantages of the proposed NGN service platform deployment method.

This paper studies and puts forward the requivements of the short message paging technology of the CDMA mobile switch system,mainly describes the technology requirements,call flow work processes and so on of the CDMA mobile switch system SMS paging service switches and adjacent switches,and the application effects of technology used in the network are also assessed.In this paper,the CDMA SMS system paging technology can significantly improve first paging success rate of the CDMA network MT message.

As the demand of multimedia value-added services becomes larger than ever before, the capacity of media resource server becomes the bottleneck of the development of these services. In this paper, a heterogeneous multi-core processor based media resource server solution is proposed based on the analysis of characteristics of media resource servers. The paper focuses on the architecture of the server and optimizing of media process under the heterogeneous multi-core architecture. Simulation test shows that the media resource server can get 2～4 times performance boost than previous solution.
