本文主要讨论七号信令系统消息传递部分(MTP)第三层中的倒换过程.首先介绍信令业务管理(STM)中倒换控制(TCOC)的状态转移图,然后讨论多倒换并发执行的冲突问题及其解决办法,最后指出该问题对于STM其他过程的普遍意义.
This article focuses on the switching process in the third layer of the signaling part of the SS7 signaling system.First, we introduce the state transition diagram of TCOC in signaling service management (STM), and then discuss the conflicts of multiple switching concurrent execution Problems and solutions, and finally points out the general significance of this issue to other STM processes.
