Abstract

本发明公开了一种网络切换的方法，位于LTE网络的UE发起的请求电路域回落CSFB的请求消息后，MME指示eNB将所述UE从LTE网络移动到2G或3G网络，并请求MSC为所述CSFB将所述UE从所述LTE网络切换到2G或3G网络的CS域，以便所述2G或3G网络为所述UE分配CS域资源，所述CS域资源用于所述UE从所述LTE网络切换到所述2G或3G网络的CS域。从而使UE能够通过从LTE网络切换到2G或3G网络的CS域的方式切换到2G或3G网络的PS域。UE在切换到PS域后，就可以进行CS域呼叫。本发明实施例降低了UE接入2G或3G网络的CS域的接入时延，缩短整个语音呼叫时长，提高用户体验。
