一种ANDSF提供接入网协议选择功能的方法和系统
摘要：
本发明公开了一种接入网发现和选择功能单元(ANDSF)提供接入网协议选择功能的方法，包括：ANDSF依据用户设备(UE)发送的接入网请求消息生成接入网列表；UE依据自身支持的接入网协议类型从接入网列表中选择接入网，并发起向选择的接入网的切换；本发明还提供了一种ANDSF提供接入网协议选择功能的系统，基于该方法和系统能够解决UE在进行接入网切换时由于UE与接入网支持的接入网协议类型不一致而导致的业务中断问题。
摘要（英）：

The invention discloses a method for providing an access network protocol selection function by an access network discovery and selection function (ANDSF), comprising: the ANDSF generates an access network list according to an access network request message sent by user equipment (UE); and the UE selects an access network from the access network list according to an access network protocol type supported by self and initiates switching to the selected access network. The invention also provides a system for providing an access network protocol selection function by an ANDSF. The method and the system can solve the problem of service interruption caused by inconsistent access network protocol types supported by the UE and the access network when the UE switches the access network.
