摘要
LTE网络是全IP网络,在Vo LTE实现以前,还需要依赖2G/3G网络实现语音业务,SRLTE是其中的一种实现方案。在这种方案中,LTE网络和终端之间需要进行一系列配合,才能保证终端在语音通话结束后接续之前的LTE通信。文中就SRLTE终端和网络的交互内容进行了介绍,给出了网络侧SIB8消息的配置建议以及在MME实现ESR功能时启用定时器的相关建议,以确保网络资源被合理有效利用。
LTE supports only packet switching with its all-IP network, and the realization of voice service depends on the 2G/3G network betbre VoLTE. SRLTE is one of the approaches. In this approach, SRLTE terminal cooperates with the LTE network to ensure that the terminal can return to the LTE network when the voice call is finished. The interaction between the SRLTE terminal and the network were introduced.
