一种基于IP的超微蜂窝系统传输控制协议

An IP Based Transport and Control Protocol for Pico-cell System

提出一种基于IP的超微蜂窝系统中BSSMAP(BSS Mobile Application Part)信令和话音的传输控制协议———BSTP(BSSMAP Simplified Transport Protocol).采用基于BSTP的传输系统,可以实现在无路由、交换式IP网络上简便、高效地传输话音业务.相对于传统SS7系统的SC-CP(Signaling Connection Control Part)和IP电话系统的RTP(Real-time Transport Protocol),BSTP协议更易于实现,并可在保证性能的前提下极大地降低系统成本.仿真分析和实际系统的话音业务试验结果均表明,BSTP协议及其传输架构是有效可行的.

This paper proposed an IP-based transport and control protocol for transporting SS7/BSSMAP （BSS Mobile Application Part） signal and voice on the pico-cell system. That is BSTP （BSSMAP Simplified Transport Protocol）. Adopting the BSTP framework, the transport system can efficiently and conveniently transport voice traffic on the switch IP network without routing. Compared with the conventional SCCP （Signaling Connection Control Part） of SS7 system and RTP （Real-time Transport Protocol） of VolP system, the proposed protocol is easier to implement. Moreover, it can reduce the system cost without performance lost. The results of simulation analysis and real system test prove the high efficiency and feasibility of the BSTP and the transport framework based on it.
