Third Generation Mobile Communication Systems (td-scdma) Transmission Network Portion (tnss)

In this paper, on the basis of researching the common model of the third generation mobile communication systems (TD-SCDMA ) and the protocols of Iu, Iub, we introduce the structure of the transfer network of RNC in detail. The interfaces between TNSS and other sub-systems (such as A4, A2 and G) are realized. At the end of this paper, we emphasis the design and realization of TNSS, including the design of the control module and the interface module.The design of TNSS is the important part of the RNC. TNSS runs on the signal processing board, the Vxworks system is used in this system, we use standard C language as the developing environment, which largely improves the software's running-speed and system resourse's occupation.
