具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
本公开实施例中涉及网络侧设备具体描述如下：网络侧设备部署在无线接入网中，为接收设备提供无线接入功能。网络侧设备可以是基站(Base Station，BS)。网络侧设备可以经由一个或多个天线与接收设备进行无线通信。网络侧设备可以为其所在地理区域提供通信覆盖。所述基站可以包括宏基站，微基站，中继站，接入点等不同类型。在一些实施例中，基站可以被本领域技术人员称为基站收发机、无线基站、接入点、无线收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、节点B(NodeB)、演进的节点B(evolved NodeB，eNB或eNodeB)或者其它一些适当的术语。示例性地，在5G系统中，基站被称为gNB。为方便描述，本公开实施例中，上述为接收设备提供无线通信功能的装置统称为网络侧设备。
本公开实施例中涉及终端设备具体描述如下：终端设备可以散布于整个移动通信系统中，并且每个终端设备可以是静止的或者移动的。终端设备还可以被本领域技术人员称为移动站、用户站、移动单元、用户单元、无线单元、远程单元、移动设备、终端设备、无线设备、无线通信设备、远程设备、移动用户站、接入终端设备、移动终端设备、无线终端设备、远程终端设备、手持设备、用户代理、移动客户端、客户端或者一些其它适当的术语。终端设备可以是蜂窝电话、个人数字助理(Personal Digital Assistant，PDA)、无线调制解调器、无线通信设备、手持设备、平板电脑、膝上型计算机、无绳电话、无线本地环路(Wireless Local Loop，WLL)站等，能够与移动通信系统中的基站进行通信。
图1为本公开实施例提供的一种广播多播业务数据接收方法的流程示意图，由终端设备执行，如图1所示，该广播多播业务数据接收方法包括以下步骤：
S101，接收网络侧发送的第一指示信息，第一指示信息用于建立终端设备与源小区的源连接和终端设备与目标小区的目标连接。
目前，终端设备在接收业务数据时，比如广播多播业务(Multicast Broadcast Service,MBS)数据，可能会存在无法接收到业务数据的情况，会产生额外的数据接收延时。比如，相关技术中，终端设备进行小区切换的过程中，若当前接收业务数据的无线承载不支持同时在源小区和目标小区建立连接，则终端设备需要先与源小区断开连接，然后再与目标小区建立连接，从而在终端设备与源小区断开连接至与目标小区成功建立连接的时间段内，终端设备没有连接上小区，无法接收到业务数据，会产生额外的数据接收延时。
本公开的实施例中，终端设备可接收网络侧发送的第一指示信息，第一指示信息用于建立终端设备与源小区的源连接和终端设备与目标小区的目标连接。
可选的，第一指示信息包括但不限于物理层控制信息、媒体接入控制(Media Access Control，MAC)层控制信息和无线资源控制(Radio Resource Control，RRC)层信息中的至少一种。
可选的，第一指示信息为针对广播多播业务的指示信息。也就是说，网络侧可响应于业务为广播多播业务，并向终端设备发送第一指示信息，第一指示信息为针对广播多播业务的指示信息。
S102，通过源连接从源小区接收广播多播业务数据。
S103，通过目标连接从目标小区接收广播多播业务数据。
