其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
图1根据本申请第一实施例的多媒体广播业务的处理方法的流程示意图。
如图1所示，本申请第一实施例的多媒体广播业务的处理方法，包括：
S101，确定目标会话中包括的业务流，以及业务流和预设的无线承载之间的映射关系。
需要说明的是，本申请实施例的多媒体广播业务的处理方法的执行主体可为接入网网络设备，接入网网络设备包括但不限于无线接入网网络设备(NG-RAN)等。
可以理解的是，一个目标会话中可包括一个或多个业务流。进一步地，还可确定业务流和预设的无线承载之间的映射关系。可选的，一个业务流可映射到唯一的无线承载，多个不同的业务流可映射到相同的无线承载。
可选的，确定业务流和预设的无线承载之间的映射关系，可包括根据本地的无线资源管理(Radio Resource Management，RRM)策略，确定业务流和预设的无线承载之间的映射关系。
例如，若根据会话上下文信息确定目标会话A中包括业务流1、业务流2和业务流3，预设的无线承载可包括无线承载MRB 1、MRB 2，则可根据RRM策略，确定业务流1、业务流2映射到无线承载MRB 1，以及确定业务流3映射到无线承载MRB 2。
S102，根据映射关系生成目标会话的分组信息。
可以理解的是，目标会话中可包括多个业务流，则可根据映射关系，将目标会话包括 的多个业务流进行分组，作为目标会话的分组信息。
可选的，根据映射关系生成目标会话的分组信息，可包括将映射到相同的无线承载的业务流作为同一分组。
例如，若目标会话A中包括业务流1、业务流2和业务流3，且确定业务流1、业务流2映射到无线承载MRB 1，以及确定业务流3映射到无线承载MRB 2，则目标会话A的分组信息可为业务流1和业务流2构成分组1，业务流3构成分组2。
S103，将分组信息发送至核心网网络设备。
可选的，将分组信息发送至核心网网络设备，可包括以下两种可能的实施方式：
方式1、将包括分组信息的会话资源建立响应消息发送至核心网网络设备。
可以理解的是，接入网网络设备在生成目标会话的分组信息之后，可生成包括分组信息的会话资源建立响应消息，并将会话资源建立响应消息发送至核心网网络设备，从而可将分组信息发送至核心网网络设备。
方式2、将包括分组信息的接口消息发送至核心网网络设备。
可以理解的是，接入网网络设备在生成目标会话的分组信息之后，还可生成包括分组信息的接口消息，并将接口消息发送至核心网网络设备，从而可将分组信息发送至核心网网络设备。
可选的，接入网网络设备为NG-RAN时，NG-RAN可将包括分组信息的NG接口信令发送至核心网网络设备。
S104，接收核心网网络设备发送的数据包及数据包的编号，数据包的编号为核心网网络设备根据分组信息得到的。
本申请的实施例中，接入网网络设备可接收核心网网络设备发送的数据包及数据包的编号，数据包的编号为核心网设备根据分组信息得到的
S105，根据数据包的编号和分组信息确定数据包对应的无线承载的序号。
本申请的实施例中，接入网网络设备在接收到数据包及数据包的编号之后，可根据数据包的编号和分组信息确定数据包对应的无线承载的序号，以建立数据包的编号和无线承载的序号之间的对应关系。其中，无线承载的序号可为分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)序号。
综上，根据本申请实施例的多媒体广播业务的处理方法，接入网网络设备能够根据会话中业务流和无线承载之间的映射关系，生成会话的分组信息并发送至核心网网络设备，然后可接收核心网网络设备根据分组信息生成的数据包编号，之后可根据数据包编号和分组信息确定数据包对应的无线承载的序号，保证了用户设备接收数据包的连续性。
在上述任一实施例的基础上，步骤S101中确定目标会话中包括的业务流，可包括接收 核心网网络设备发送的会话资源建立请求，会话资源建立请求中包括目标会话的会话上下文信息，然后根据会话上下文信息确定目标会话中包括的业务流。
本申请的实施例中，接入网网络设备可接收核心网网络设备发送的会话资源建立请求，会话资源建立请求用于建立会话资源，会话包括但不限于多媒体广播业务(Multimedia Broadcast Service，MBS)会话等，这里不做过多限定。其中，会话资源建立请求中包括目标会话的会话上下文信息。可选的，会话资源建立请求中还可包括服务质量(Quality of Service，QOS)信息。
可选的，接入网网络设备为NG-RAN时，NG-RAN可通过NG接口信令接收核心网网络设备发送的会话资源建立请求。
进一步地，接入网网络设备可根据会话上下文信息确定目标会话中包括的业务流。
由此，该方法中接入网网络设备能够根据核心网网络设备发送的会话资源建立请求中的目标会话的会话上下文信息，确定目标会话中包括的业务流。
在上述任一实施例的基础上，步骤S105中确定数据包对应的无线承载的序号之后，可包括将数据包和数据包对应的无线承载的序号发送至用户设备(User Equipment，UE)。
可以理解的是，用户设备可根据数据包对应的无线承载的序号对数据包进行排序，保证了接收数据包的连续性。
可选的，当用户设备发生移动等情况下，用户设备接收数据包的顺序可能会出现紊乱，则此时用户设备可根据数据包对应的无线承载的序号对数据包进行无损重传，以保证用户设备接收数据包的连续性，还可实现会话的无损移动操作。
由此，该方法在确定数据包对应的无线承载的序号之后，还可将数据包和数据包对应的无线承载的序号发送至用户设备，保证了用户设备接收数据包的连续性，解决了相关技术中因用户设备移动导致的数据包接收紊乱的问题，可实现会话的无损移动操作。
图2根据本申请第二实施例的多媒体广播业务的处理方法的流程示意图。
如图2所示，本申请第二实施例的多媒体广播业务的处理方法，包括：
S201，将更新分组信息发送至核心网网络设备，以供核心网网络设备将分组信息更新为更新分组信息，并根据更新分组信息生成数据包的更新编号。
需要说明的是，本申请实施例的多媒体广播业务的处理方法的执行主体可为接入网网络设备，接入网网络设备包括但不限于无线接入网网络设备(NG-RAN)等。
可以理解的是，目标会话的分组信息可能会发生变化，此时接入网网络设备可根据更新映射关系生成更新分组信息。
