摘要： The embodiments of the present invention disclose a handover method and a mobility management network element. The method includes: a target mobility management network element receives a forward relocation request message sent by a source mobility management network element, where the forward relocation request message includes single radio voice call continuity SRVCC capability information; and the target mobility management network element sends, to an target access network element, a first request message that carries information of SRVCC operation possible. The present invention also provides a corresponding mobility management network element. The embodiments of the present invention provide a handover method and a mobility management network element. The source mobility management network element indicates whether the target mobility management network element is SRVCC capable through the forward relocation request, which enables the target mobility management network element to correctly indicate that the target radio access network network element is SRVCC capable, and enables the target radio access network network element to correctly trigger an SRVCC handover, and saves network's signaling exchanges, and ensures correct usage of a user's voice service.
摘要翻译：本发明的实施例公开了切换方法和移动性管理网络元件。该方法包括：目标移动性管理网元接收源移动性管理网元发送的前向重定位请求消息，其中前向重定位请求消息包括单无线语音呼叫连续性SRVCC能力信息; 并且目标移动性管理网元向目标接入网元发送可携带SRVCC操作信息的第一请求消息。本发明还提供了相应的移动性管理网络元件。本发明的实施例提供了切换方法和移动性管理网元。源移动性管理网元指示目标移动管理网元是否通过前向重定位请求具有SRVCC能力，使得目标移动性管理网元能够正确地指示目标无线接入网络网元具有SRVCC能力，并使能目标无线接入网络网元正确触发SRVCC切换，节省网络信令交换，保证用户语音业务的正常使用。

摘要： The embodiments of the present invention relate to a method, an apparatus, and a system for selecting a public land mobile network. The method includes: acquiring, by an eNodeB, PLMN information about a CSFB; and determining, by the eNodeB, a target cell of a packet switching handover according to the PLMN information about the CSFB. In the embodiments of the present invention, the eNodeB acquires the PLMN information about the CSFB, and the eNodeB determines the target cell of the packet switching handover according to the acquired PLMN information about the CSFB, so as to switch to the PLMN where the MSC/VLR attached by the UE in the EPS network is located, thereby avoiding an additional processing delay of the CSFB procedure caused when an eNodeB selects a different PLMN for failing to perceive the PLMN where the MSC/VLR attached by the UE in the EPS network is located in the CSFB procedure, and improving the service success rate.
摘要翻译：本发明的实施例涉及一种用于选择公共陆地移动网络的方法，装置和系统。该方法包括：由eNodeB获取关于CSFB的PLMN信息; 以及由eNodeB根据关于CSFB的PLMN信息来确定分组交换切换的目标小区。在本发明的实施例中，eNodeB获取关于CSFB的PLMN信息，并且eNodeB根据获取的关于CSFB的PLMN信息来确定分组交换切换的目标小区，以便切换到PLMN，其中MSC 位于EPS网络中的UE连接的VLR / VLR，从而避免了当eNodeB选择不同的PLMN以使其不能感知到由该UE在EPS网络中附着的MSC / VLR的PLMN时引起的CSFB过程的附加处理延迟位于CSFB程序中，提高服务成功率。
