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,所描述的实施例仅仅是本申请一部分实施例,并不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做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。
为了便于更加清晰地理解本申请各实施例的技术方案,首先对本申请各实施例相关的一些技术内容进行介绍。
多媒体广播多播服务(Multimedia Broadcast Multicast Services,MBMS)作为一种重要的服务类型,在3G和4G技术中已经长期存在,但在5G新空口(New Radio,NR)***中,已经支持单播服务,鉴于MBMS服务对某些垂直领域(比如车联网,公共安全)的重要性,也增加了支持多播广播(5G中称多播广播服务(Multicast Broadcast Services,MBS),以下涉及5G时将统一称为MBS)的服务。
通常将MBS分为多播业务(multicast service)(在多播会话(multicast session)上承载,以下将多播业务或者多播会话统称多播会话)和广播业务(broadcast)。其中,处于任意RRC状态的UE,均可以接收广播业务的业务数据,而多播(multicast)业务的业务数据仅支持UE在RRC连接态下接收。
UE在连接态下接收多播会话时,网络可以配置多种机制(如基于混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈的重传,或者通过点到点(Point To Point,PTP)方式传输多播会话数据)以保证多播会话数据传输的可靠性。
多播业务接收的连续性是一项基本要求。为了保证支持UE在RRC非激活态下接收多播业务的业务数据,对于在RRC非激活态下接收多播业务的业务数据的UE,在进行小区重选驻留到目标小区后,应当能够继续接收该多播业务的业务数据。
然而,目前UE在小区重选过程中如何保证多播业务接收的连续性尚无解决方案,如果沿用传统的广播业务的方案,接收多播业务的业务数据的终端需要从目标小区读取所涉及多播业务的全部配置后,才能继续在目标小区接收该业务,由于终端处于非激活态下,在接入目标小区之后,有可能无法获取该多播业务的多播配置信息,导致无法连续接收该多播业务的业务数据。
针对上述问题,本申请各实施例提供一种解决方案,通过终端根据多播业务配置信息对应的指示信息,将在第二小区接收第一多播业务所使用的部分或者全部的多播业务配置,确定为第一多播业务的第一多播业务配置,然后根据该第一多播业务的第一多播业务配置,在第一小区接收第一多播业务的业务数据,使得终端在接入第一小区后,能够继续接收第一多播业务的业务数据,保持了多播业务接收的连续性。
图1为本申请实施例提供的多播业务的业务数据接收方法的流程示意图之一,该方法可应用于终端,如图1所示,该方法包括如下步骤:
步骤100、终端在接入第一小区的情况下,根据多播业务配置信息对应的指示信息,确定第一多播业务的第一多播业务配置,其中,第一多播业务配置包含在第二小区接收第一多播业务所使用的部分或者全部的多播业务配置。
步骤101、根据第一多播业务的第一多播业务配置,在第一小区接收第一多播业务的业务数据。
具体地,在实际网络部署中,针对特定多播业务,不同小区发送该多播业务所用的配置可能相同或部分相同,因此,本申请实施例中,针对第一多播业务(可以是任意一种多播业务,具体不做限制),终端可以在接入第一小区的情况下,根据多播业务配置信息对应的指示信息,确定该第一多播业务的第一多播业务配置,该第一多播业务配置包含了终端在第二小区接收第一多播业务所使用的部分或者全部的多播业务配置,然后终端可以根据该第一多播业务配置,在第一小区接收该第一多播业务的业务数据。
本申请实施例提供的多播业务的业务数据接收方法,终端可以根据多播业务配置信息对应的指示信息,将在第二小区接收第一多播业务所使用的部
分或者全部的多播业务配置,确定为第一多播业务的第一多播业务配置,然后根据该第一多播业务的第一多播业务配置,在第一小区接收第一多播业务的业务数据,从而终端在接入第一小区后,能够继续接收第一多播业务的业务数据,保持了多播业务接收的连续性。
可选地,该方法还包括:接收网络设备发送的多播业务配置信息对应的指示信息。
具体地,一种可能的实现方式中,上述多播业务配置信息对应的指示信息可以是网络设备(例如基站)发送给终端的。
可选地,终端接收网络设备发送的多播业务配置信息对应的指示信息,可以包括:接收网络设备发送的RRC释放消息,该RRC释放消息中携带指示信息;或者,接收网络设备发送的MCCH,该MCCH中携带指示信息。
例如,网络设备可以在向终端发送的RRC释放消息中包含该指示信息,在该终端从RRC连接态(本申请中简称连接态)被释放到RRC非激活态(本申请中简称非激活态)或RRC空闲态(本申请中简称空闲态),并进行小区重选驻留到目标小区后,该终端可以根据该指示信息,确定是否可以重用或者部分重用在源小区接收第一多播业务的配置,在目标小区继续接收该第一多播业务。
例如,网络设备可以在向非激活态或空闲态终端发送的多播控制信道(Multicast Control Channel,MCCH)中包含该指示信息,后续该终端进行小区重选驻留到目标小区后,该终端可以根据该指示信息,确定是否可以重用或者部分重用在源小区接收第一多播业务的配置,在目标小区继续接收该第一多播业务。
可选地,上述指示信息可用于指示终端在第一小区与第二小区接收同一个多播业务的业务数据所使用的多播业务配置是否相同;其中,第一小区可以为第二小区的邻小区;或者,第一小区可以为小区切换或小区重选后的目标小区,第二小区为小区切换或小区重选前的源小区。
可选地,上述指示信息可以包括以下一种或多种:

多播广播服务MBS配置是否相同。
比如,在进行小区重选驻留到目标小区后,若终端根据第一指示信息,确定目标小区与源小区中第一多播业务的MBS配置相同,则终端可以重用在源小区接收第一多播业务所使用的MBS配置,在驻留目标小区后继续接收该第一多播业务。
(2)第二指示信息,用于指示第二小区发送的第一多播业务的MBS配置的使用范围。
比如,在进行小区重选驻留到目标小区后,若终端根据第二指示信息,确定目标小区位于源小区发送的第一多播业务的MBS配置的使用范围内,则终端可以重用在源小区接收第一多播业务所使用的MBS配置,在驻留目标小区后继续接收该第一多播业务。
(3)第三指示信息,用于指示第一小区与第二小区的第一多播控制信道MCCH的配置是否相同,第一MCCH用于发送第一多播业务的MBS配置。
其中,第一MCCH的配置指的是小区发送第一MCCH所使用的配置,第一MCCH指的是小区用于发送第一多播业务的MBS配置的MCCH。
比如,在进行小区重选驻留到目标小区后,若终端需要通过读取目标小区发送的第一MCCH来获取在目标小区接收第一多播业务所使用的MBS配置,终端可以根据第三指示信息,确定目标小区发送第一MCCH所使用的配置与源小区发送第一MCCH所使用的配置是否相同,若相同,则终端可以重用在源小区接收第一MCCH所使用的配置,如直接应用源小区的***消息块(System Information Block,SIB)20中的MCCH配置接收目标小区的第一MCCH。
(4)第四指示信息,用于指示第二小区的第一MCCH的配置的使用范围,第一MCCH用于发送第一多播业务的MBS配置。
比如,在进行小区重选驻留到目标小区后,若终端需要通过读取目标小区发送的第一MCCH来获取在目标小区接收第一多播业务所使用的MBS配置,终端可以根据第四指示信息,确定目标小区是否位于源小区的第一MCCH的配置的使用范围内,若是,则终端可以重用在源小区接收第一MCCH所使
用的配置,如直接应用源小区的SIB20中的MCCH配置接收目标小区的第一MCCH。
可选地,前文所述的使用范围可以包括以下任一种:
(1)无线接入网通知区域(Radio Access Network Notification Area,RNA)内使用,也即在同一个RNA内的其他小区可以使用第二小区的相应多播业务配置。
比如,若指示信息指示第二小区发送的第一多播业务的MBS配置的使用范围是RNA内使用,而第一小区与第二小区在同一RNA内,则表明第一小区位于第二小区发送的第一多播业务的MBS配置的使用范围内。
比如,若指示信息指示第二小区发送第一MCCH所使用的配置的使用范围是RNA内使用,而第一小区与第二小区在同一RNA内,则表明第一小区位于第二小区发送第一MCCH所使用的配置的使用范围内。
(2)第二小区使用,也即除第二小区以外的其他小区不使用第二小区的多播业务配置。
比如,若指示信息指示第二小区发送的第一多播业务的MBS配置的使用范围是第二小区使用,则表明第一小区不使用第二小区发送的第一多播业务的MBS配置,这种情况下,终端可以从第一小区获取第一小区发送的第一多播业务的MBS配置。
比如,若指示信息指示第二小区发送第一MCCH所使用的配置的使用范围是第二小区使用,则表明第一小区不使用第二小区发送第一MCCH所使用的配置,这种情况下,终端可以读取第一小区的SIB20来获取在第一小区接收第一MCCH所使用的配置。
(3)第一小区列表中的小区使用,也即在该第一小区列表中的小区可以使用第二小区的相应多播业务配置。其中第一小区列表指的是指示信息所指示的任意小区列表,具体不做限定。
比如,若指示信息指示第二小区发送的第一多播业务的MBS配置的使用范围时,指示的第一小区列表中包含第一小区,则表明第一小区位于第二小区发送的第一多播业务的MBS配置的使用范围内。
比如,若指示信息第二小区的第一MCCH的配置的使用范围时,指示的第一小区列表中包含第一小区,则表明第一小区位于第二小区的第一MCCH的配置的使用范围内。
可选地,在第一指示信息指示第一小区与第二小区中第一多播业务的MBS配置不同的情况下,第一指示信息还用于指示:

(1)在确定第一小区与第二小区中第一多播业务的MBS配置相同,或者第一小区位于第二小区发送的第一多播业务的MBS配置的使用范围内的情况下,将在第二小区接收第一多播业务所使用的MBS配置,确定为第一多播业务的第一多播业务配置。
具体地,若终端根据指示信息确定第一小区与第二小区中第一多播业务的MBS配置相同,或者第一小区位于第二小区发送的第一多播业务的MBS配置的使用范围内,则终端可以将在第二小区接收第一多播业务所使用的MBS配置,确定为第一多播业务的第一多播业务配置,也即重用在第二小区接收第一多播业务所使用的MBS配置,并根据该第一多播业务配置,在第一小区接收第一多播业务的业务数据。
(2)在确定第一小区与第二小区中第一多播业务的MBS配置部分相同的情况下,将在第二小区接收第一多播业务所使用的MBS配置中与第一小区相同的部分,确定为第一多播业务的第一多播业务配置。

其中,第一小区为第二小区的邻小区;或者,第一小区为切换或重选后的目标小区,第二小区为切换或重选前的源小区。
具体地,在实际网络部署中,针对特定多播业务,不同小区发送该多播业务所用的配置可能相同或部分相同,因此,本申请实施例中,针对第一多播业务(可以是任意一种多播业务,具体不做限制),网络设备可以向终端发送多播业务配置信息对应的指示信息,指示终端在第一小区与第二小区接收同一个多播业务的业务数据所使用的多播业务配置是否相同,以便终端在接

实施例1:基站向UE指示邻小区和服务小区的第一MBS配置是否相同。
步骤1、对于当前小区正在发送的第一多播业务,基站指示特定邻小区是否使用和服务小区相同的配置发送该多播业务,如果配置不同,可选地进一步指示UE是否需要进入RRC连接态获取该不同配置。
步骤2、UE在小区重选时,根据步骤1中所述指示,判断目标小区是否使用相同的配置,如果配置相同,则在驻留目标小区后直接继续接收该多播业务。如果配置不同,则可以在驻留该目标小区后,根据指示,留在RRC非激活态或RRC空闲态,或者进入RRC连接态获取配置的不同部分。
步骤3、UE继续接收该多播业务。
实施例2:基于实施例1的指示,在邻小区的第一MBS配置与服务小区不同的情况下,基站向UE指示邻小区的MCCH配置(即SIB20中的MCCH配置)是否和服务小区相同。
