The Research Of Core Network Fusion In 2G And 3G

As the mobile communications into the 3G era, the operators are facing the same issue-the new 3G networks and mature 2G network of relations. With regard to the coexistence of 2G and 3G, at present there are two major programs, namely, integration of networking and individual networking. Among them, converged networking benefit of operators and the efficient use of network resources, the user can not be used directly for No.3G business, operation and maintenance also possess a clear advantage, a separate group of networks with the network structure is clear,3G network construction on the 2G less affected advantage. Therefore, the choice of a networking program is the construction of 3G network operators, when the first problem to be solved. This detailed analysis of the integration of networking and networking are two separate programs with their respective advantages and disadvantages, taking into account the existence of two kinds of programs from different backgrounds and characteristics that the current situation, the integration of networking programs have more obvious advantages.This paper analyzes the integration of the actual needs of network schemes proposed integration of the overall objectives and the actual situation of the network decomposition of the fusion target, for different equipment and systems integration programs were developed. The core network in the current stage of development,2G and 3G convergence occurs mainly in CS domain, can be said that CS domain integration and transformation is the focus of integration. In this paper, Beijing China Mobile's network integration as an example, a detailed study of the CS domain fusion of the main tasks:HLR fusion, MSC integration (including the RNC soft-switching equipment construction and access, etc.) and then road the Fusion (VoIP transformation). Finally, after the adoption of converged data networks and equipment operation, reflecting the impact of integration work for the network reflects the integration of work conducted and results verified the feasibility of fusion network.
