WCDMA核心网信令系统对七号信令网的影响

BICC和GCP是第三代移动网络中必不可少的信令,主要支持的承载网络是ATM和IP,许多厂商也侧重开发ATM和IP传输技术。在中国未来几年逐渐开展3G移动业务后,GSM网络的业务也可以逐渐连接到3G核心网络中,GSM也会支持分层网络,使用比STM更经济的IP作为传输,原来七号信令网络中的流量就会逐渐减少。在设计3G七号信令网络时,需要考虑3G网络信令对传输的要求,为将采用的新技术进行准备。

Impact of WCDMA Core Network Signaling System on SS7 Signaling Network

BICC and GCP are necessary sig-nalings in3G mobile communication network.Their main supporting carrier networks are ATM and IP.Many manufacturers also focus on the develop ment of ATM and IP trans-mis sion tech nolo gies.After3G mobile com-muni cation service is intro duced in Chi na in next few years,GSM network services can also be connected to3G core network.GSM can support layer network.By using IP as transmission which is cheaper than STM,the flow in SS7network will de crease.In the design of3G SS7network,re quirements of3G network signaling for transmis sion should be con sidered to pre pare for new technolo-gies to be de ployed.
