LTE时代信令网网络组织与演进

Network Organization and Evolution of Signaling Network in LTE Era

LTE网络采用全IP网络架构,对比2G/3G时代以TDM为主的网络组织完全不同,LTE网络内部各网元间通信、LTE网与2G/3G网、固定电话网等网间互通如何实现。从信令演进趋势看,Diameter协议将取代传统的SS7协议,成为LTE网络广泛应用的核心网网元间通信协议,未来信令网络的发展趋势为IP化,Diameter信令网将长期与SS7信令网共存。

Used in LTE network all IP network architecture, compared with 2G / 3G era to TDM network organization is completely different, LTE network between each element communication, 2G / 3G and LTE networks, fixed telephone network exchange to realize. Signaling from the developing trend, diameter protocol will replace traditional SS7 protocol, become widely used in LTE network core network communication protocol, signaling network in the future development trend of IP, diameter signaling network long-term and SS7 signaling network coexist.
