网络中激活态AN之间软切换及会话迁移的实现方法
摘要：
本发明涉及一种网络中激活态AN之间软切换及会话迁移的实现方法。本发明主要包括：当激活态的源接入网AN确定需要进行切换操作时，源AN根据用户终端发来的路由更新消息与目标AN之间进行信息交互，并建立源AN与目标AN之间的通信连接，包括信令连接和业务连接；之后，基于建立的通信连接在源AN与目标AN之间实现软切换处理以及会话的迁移处理。因此，本发明实现了HRPD系统AN间、PCF间激活态软切换，维持业务的连续性；通过会话迁移，将终端会话平滑迁移到目标AN。
摘要（英）：

The present invention relates to a network active state AN soft switching and conversation migrant implementation method. Said invention mainly includes active state source access network AN determining request to make switching operation, source AN according to user terminal sent route updating message to make information interaction with target AN, and establishing communication linkage betweensource AN with target AN, including signaling and service connection; based established communication linkage to realize soft switching processing and conversational migration processing between sourceAN and target AN. Therefore said invention realizes active state soft switching between HRPD system AN and PCF, through conversation migration smoothing migration terminal session to target AN.
