我国900MHz模拟蜂窝移动电话实现系统间联网使我国模拟蜂窝移动电话网的覆盖范围列居世界首位。本文简要介绍了摩托罗拉和爱立信两大系统的网络结构,指出两大系统互联关键在于交换机间的信令配合;重点叙述了系统间互联信令网的构成,传输层X.25与CC7的协议转换,移动应用层协议规程MTUP信令与IS-41信令的转换。
China’s 900MHz analog cellular mobile phone system to achieve inter-system network so that China’s cellular network coverage of analog cellular mobile phones ranked first in the world. This article briefly introduces the network structure of the two systems of Motorola and Ericsson and points out that the key to the interconnection between the two systems lies in the signaling cooperation between the switches. The structure of the interconnection signaling network between systems, the protocol conversion between the transport layer X.25 and CC7 , Mobile application layer protocol protocol MTUP signaling and IS-41 signaling conversion.
