The Design And Realization Of The V5 Interface Protocol For Cdma Wireless Access Systems

It is expensive that put mobile communication system in the place people few and far between. How to solve the issue is a problem now.V5.2 interface protocol and software structure of CDMA wireless access system are studied mainly in this paper, the design of V5.2 interface in the system is finished. The design make the CDMA access system access PSTN without MSC, while offer all the telecom service.The design of V5-module system structure is described in detail. Before design the software for the V5-module of the whole system, according to the V5 protocol and the realization of the CDMA wireless access system, the software is compartmentalized into three modules according to the functions. The modules running in the equipment are carried out based on the hierarchy status machine. The paper presents distributed projects for the realization of VLR (visit location register) in the research of V5 user manage module design. Base on the project the system capability can be enlarged linearly and the load of the module can be proportion. It makes the system more robust.The design in the paper has finished the test in the lab and the test telecommunication office has started in the Saudi Arabia, Mexico and the Morocco. In times to come they will be put into use and offer the convenient service to the local user.
