七号信令在现代通信中的应用

七号信令是国际标准化公共信道信令，介绍了七号信令的网络结构和功能结构，及其在公用电话网(PSTN)／综合业务数据网(ISDN)、移动通信网和智能网中的应用。随着现代通信网的快速发展，七号信令有必要引入高速信令链路以解决网络拥塞问题，同时对第三代移动通信系统将影响到现有七号信令的网络结构与协议，七号信令也要与下一代IP网络的融合，以实现电信网与下一代网络体系的互通等问题进行了进一步探讨。

Implementation of No.7 Signaling in Modern Communications

No.7 signaling is an international standard common channel signaling. This paper describes the network and function structure of No.7 signaling and its application in PSTN/ISDN, mobile communication network and intelligence network. Because of fast development of modern communications networks, it is necessary to adopt highspeed signaling link to solve the problem of network congestion. The network structure and protocol of No.7 signaling will be influenced 3G mobile communications. No.7 signaling will mergence with the next generation IP network to accomplish the interlinking between telecommunications network and the next generation network, the paper discussed the problem deeply.
