具体实施方式
为了便于理解本申请实施例，首先介绍以下技术点。
(1)MBMS业务接收连续性。
参见图1，相关4G技术中，系统信息(比如SIB15)中包含了同频和异频邻小区支持的MBMS业务区域标识(Service Area Identities，SAI)列表，根据本地存储的用户服务描述(User Service Description，USD)列表，以及SIB15中的SAI列表，终端无需读取邻小区系统信息，即可判断某个频点是否支持某个MBMS服务。空闲态的UE根据服务小区的系统信息(SIB15)选择支持MBMS业务的邻小区以保证空闲态下移动过程中的MBS业务连续性。
参见图2，相关4G技术下，在单小区点到多点(Single Cell Point To Multipoint，SC-PTM)模式控制信道上的SC-PTMConfiguration消息中，包含了当前服务小区正在进行中的MBMS服务列表，以及支持每个MBMS服务的4G邻小区列表。
处于连接态的UE，当发生切换时，如果目标小区不支持当前MBMS业务，则UE提前建立单播承载接收MBS业务以保证UE在连接状态下从支持MBMS业务的小区切换到不支持MBMS业务的小区时MBMS业务接收的连续性。
(2)MBMS业务覆盖区
LTE技术下，每个MBMS业务对配置一个MBMS服务区(MBMS service area)，服务区可能是固定的，也可能是动态调整的，不属于特定MBMS业务的服务区的小区不能提供相应的MBMS业务。LTE下的动态调整MBMS服务区是在核心网的控制下。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
