Description

多播业务的处理方法、装置及设备
相关申请的交叉引用
本申请基于申请号为202111073048.1、申请日为2021年09月14日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信技术领域，特别是指一种多播业务的处理方法、装置及设备。
背景技术
对于支持多播业务的用户设备(User Equipment，UE)，如果它在通过加入(join)流程加入多播广播服务(Multicast and Broadcast Service，MBS)组后进入空闲(idle)态或非激活(Inactive)态，当业务将开始前，网络侧将根据所存储的信息寻呼用户设备，告知即将开始会话(session start)，使用户设备重新进入连接态接收业务。对于支持多播(multicast)的节点(即用户设备)，将通过组寻呼(group paging/group notification)方式寻呼用户设备，对于不支持多播的节点，将通过正常的单播寻呼(unicast paging)方式寻呼用户设备。
然而，由于业务标识(如多播广播服务会话(MBS session)标识(比如ID))会在寻呼消息(paging message)中携带，也即用户设备需要在相应的寻呼时机(Paging Occasion，PO)醒来接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)后再接收包括寻呼消息的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)来确认是否有其订阅或感兴趣的业务即将开始，因此对于部分用户设备来说，可能有不必要的功耗(接收PDSCH后发现没有其订阅或感兴趣的业务)。

在本申请的各种实施例中，应理解，下述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
另外，本申请实施例中术语“系统”和“网络”常可互换使用。
在本申请所提供的实施例中，应理解，“与A相应的B”表示B与A相关联，根据A可以确定B。但还应理解，根据A确定B并不意味着仅仅根据A确定B，还可以根据A和/或其它信息确定B。
如图1所示，本申请实施例提供一种多播业务的处理方法，由用户设备执行，包括：
步骤101，接收网络侧设备发送的第一指示信息，所述第一指示信息用于指示一个或多个多播业务待开始，或者，指示一组或多组多播业务待开始，或者，指示是否需要用户设备进入连接态接收多播业务；
步骤102，在所述第一指示信息指示一个或多个多播业务待开始的情况下，加入多播业务组；或者，
步骤103，在所述第一指示信息指示多个多播业务待开始，或者指示一组或多组多播业务待开始的情况下，接收寻呼消息；或者，
步骤104：在所述第一指示信息指示用户设备进入连接态接收多播业务的情况下，接收寻呼消息。
其中，多播业务组是指一个多播业务对应的多个用户设备组。而且，若第一指示信息指示一个或多个多播业务待开始，用户设备能够通过该第一指示信息，了解到该一个或多个多播业务是哪个或哪些多播业务。
这样，按照上述步骤101至104，用户设备能够在接收网络侧设备发送 的第一指示信息后，根据该第一指示信息，在其指示一个或多个多播业务待开始的情况下，直接加入多播业务组，无需接收寻呼消息；在其指示一组或多组多播业务待开始的情况下或者在其指示用户设备进入连接态接收多播业务的情况下，再接收寻呼消息，根据寻呼消息来判断是否加入多播业务组或者是否进入连接态接收多播业务。这样，用户设备可以减少因接收寻呼消息而造成的不必要的功耗。
其中，用户设备可以在网络侧设备配置的时刻接收该第一指示信息，网络侧设备配置的时刻可以是PO对应的时刻，换句话说，网络侧设备会在PO对应的时刻发送该第一指示信息。
实际应用时，该第一指示信息可以包括物理层消息，换句话说，该第一指示信息可携带于PDCCH，或者在携带寻呼信息的PDSCH之前的PDCCH中携带；或者，该第一指示信息也可携带于用户设备的唤醒信号。
在一实施例中，在所述第一指示信息用于指示一个或多个多播业务待开始或者指示一组或多组多播业务待开始的情况下，所述第一指示信息可以包括N1个比特(bit)的信息，每个比特对应一个或一组多播业务，其中N1为正整数。
这里，在第一指示信息用于指示一个或多个多播业务待开始或者指示一组或多组多播业务待开始的情况下，第一指示信息的一种实现为N1个比特的信息，每个比特对应一个或一组多播业务，换句话说，每比特指示一种或一组多播业务是否待开始(即将开始)，如比特位为1，表示该比特位对应的某个或某组多播业务中的一个或多个多播业务即将开始。假设N1＝2，第一个比特位对应第一个(组)多播业务，第二个比特位对应第二个(组)多播业务，比特为“1”表示多播业务待开始，则“01”指示仅有该第二个(组)多播业务待开始，“10”指示仅有该第一个(组)多播业务待开始。
实际应用时，在第一指示信息用于指示是否需要用户设备进入连接态接收多播业务的情况下，第一指示信息可以通过1比特实现。示例性地，在第一指示信息为1的情况下，第一指示信息可以指示用户设备进入连接态接收多播业务，在第一指示信息为0的情况下，第一指示信息可以指示用户设备不进入连接态接收多播业务；或者，在第一指示信息为0的情况下，第一指示信息可以指示用户设备进入连接态接收多播业务，在第一指示信息为1的情况下，第一指示信息可以指示用户设备不进入连接态接收多播业务。
为了使用户设备能够明确待开始的多播业务，在一实施例中，所述接收网络侧设备发送的第一指示信息之前，该方法还可以包括：
接收网络侧设备发送的第二指示信息；
其中，所述第二指示信息包括第一对应关系，所述第一对应关系包含所述每个比特与一个或一组多播业务的对应关系。
这里，接收网络侧设备发送的第二指示信息，由于该第二指示信息包括所述每个比特与一个或一组多播业务的对应关系，用户设备在接收该第二指示信息后，能够了解N1个比特的每个比特对应的一个或一组多播业务，从而，在接收到第一指示信息后，确定即将开始的一个或多个多播业务。
其中，该第二指示信息可以是网络侧设备通过系统消息广播，或者仅在用户设备注册或加入多播业务组时通过RRC消息配置给用户设备的。当然，若用户设备收到了系统消息广播的第二指示信息，以及收到在其注册或加入多播业务组时通过RRC配置的第二指示信息，则对于该用户设备仅有通过该RRC配置的第二指示信息有效。
另外，考虑到第一对应关系的时效性，在一实施例中，所述第二指示信息还可以包括第一有效周期，所述第一有效周期为所述第一对应关系的有效周期。
这里，第一有效周期也可理解为第一对应关系的变更周期。网络侧设备可以配置第一有效周期，如与系统消息SI或多播控制信道(Multicast Control Channel，MCCH)变更周期相同或是其倍数。用户设备会在该第一有效周期到达时检查是否第一对应关系有改变。
在一实施例中，在所述第一指示信息用于指示一个或多个多播业务待开始或者指示一组或多组多播业务待开始的情况下，所述第一指示信息可以包括N2个比特的信息，所述N2个比特的不同取值与一个或一组多播业务对应，其中N2为正整数。
这里，在第一指示信息用于指示一个或多个多播业务待开始或者指示一组或多组多播业务待开始的情况下，第一指示信息的另一种实现为N2个比特的信息，该N2个比特的不同取值对应一个或一组多播业务，换句话说，N2个比特的不同组合的值，指示对应的一种或一组多播业务是否待开始(即将开始)，如N2＝5，5比特组合的取值表示一个业务，如“00001”表示业务1或业务组1即将开始，“00010”表示业务2或业务组2即将开始。其中N2个比特的取值即包括N2个比特的字符串。
在一实施例中，所述接收网络侧设备发送的第一指示信息之前，该方法还可以还包括：
接收网络侧设备发送的第三指示信息；
其中，所述第三指示信息包括第二对应关系，所述第二对应关系包含所述N2个比特的不同取值与一个或一组多播业务的对应关系。
类似于第二指示信息，这里，接收网络侧设备发送的第三指示信息，由于该第三指示信息包括所述N2个比特的不同取值与一个或一组多播业务的对应关系，用户设备在接收该第三指示信息后，能够了解N2个比特的每个值对应的一个或一组多播业务，从而，在接收到第一指示信息后，确定即将开始的一个或多个多播业务。
其中，该第三指示信息可以是网络侧设备通过系统消息广播，或者仅在用户设备注册或加入多播业务组时通过RRC消息配置给用户设备的。当然，若用户设备收到了系统消息广播的第三指示信息，以及收到在其注册或加入多播业务组时通过RRC配置的第三指示信息，则对于该用户设备仅有通过该RRC配置的第三指示信息有效。
另外，考虑到第二对应关系的时效性，在一实施例中，所述第三指示信息还可以包括第二有效周期，所述第二有效周期为所述第二对应关系的有效周期。
这里，第二有效周期也可理解为第二对应关系的变更周期。网络侧设备可以配置第二有效周期，如与系统消息SI或MCCH变更周期相同或是其倍数。用户设备会在该第二有效周期到达时检查是否第二对应关系有改变。
在一实施例中，在所述第一指示信息指示一组或多组多播业务待开始的情况下，所述接收寻呼消息之后，该方法还可以包括：
获取所述寻呼消息中的多播业务标识；
根据所述多播业务标识，确定是否加入多播业务组。
其中，用户设备在第一指示信息指示一组或多组多播业务待开始的情况下接收寻呼消息，之后会获取该寻呼消息中的多播业务标识，来确定所指示的一组或多组多播业务中的多播业务是否是用户设备感兴趣的多播业务，从而确定是否加入对应的多播业务组。
即，对于指示某组多播业务的情况，当用户设备通过读取的第一指示信息知道该组多播业务中有某一个或多个多播业务即将开始，用户设备需继续接收寻呼消息，经获取该寻呼消息中的多播业务标识，再决定是否需要醒来加入多播业务组。若该组多播业务中有用户设备感兴趣的某个多播业务，则加入该多播业务的多播业务组；若该组多播业务中有用户设备感兴趣的某个多播业务，则加入该多播业务的多播业务组。
实际应用时，所述多播业务标识可以包括多播广播服务会话(MBS session)标识(比如ID))、临时移动组标识(TMGI)、互联网协议(IP)地址(address)等，本申请实施例对所述多播业务标识的具体实现方式不作限定，只要实现其功能即可。
在一实施例中，在所述第一指示信息指示用户设备进入连接态接收多播业务的情况下，所述接收寻呼消息之后，该方法还可以包括：
获取所述寻呼消息中的多播业务标识；
根据所述多播业务标识，确定是否发起RRC连接建立，即确定是否进入连接态接收多播业务。
其中，在所述第一指示信息指示用户设备进入连接态接收多播业务的情况下，该用户设备处于非激活态。具体地，对于处于非激活态的用户设备，当该用户设备接收到指示进入连接态接收多播业务的第一指示信息时，需要根据寻呼消息中的多播业务标识来确定具体需要在连接态接收的多播 业务，如果该多播业务标识对应的多播业务是用户设备感兴趣的多播业务和/或用户设备订阅(即需要接收)的多播业务，则用户设备可以决定(即确定)发起RRC连接建立以进入连接态，并在进入连接态后接收该多播业务标识对应的多播业务；如果该多播业务标识对应的多播业务是用户设备不感兴趣的多播业务和/或用户设备未订阅(即不需要接收)的多播业务，则用户设备可以不发起RRC连接建立，即不进入连接态接收该多播业务标识对应的多播业务。
在一实施例中，该方法还可以包括：
在所述第一指示信息用于指示一组或多组多播业务待开始的情况下，接收网络侧设备发送的第四指示信息，所述第四指示信息用于指示多播业务的分组信息。
换句话说，网络侧设备可以通过第四指示信息告知用户设备多播业务的分组信息，以便用户设备了解一组多播业务包含的多播业务信息。
其中，该第四指示信息可以由网络侧设备通过系统消息或RRC配置下发给用户设备。
实际应用时，该第四指示信息可以包括每个多播业务对应的组号。具体地，网络侧设备可以配置多个多播业务组，向用户设备发送的系统消息或RRC配置可以包括每个多播业务对应的组号，以及其对应的第一指示信息的比特位或比特串。
如图2所示，本申请实施例还提供一种多播业务的处理方法，由网络侧设备执行，包括：
步骤201，发送第一指示信息，所述第一指示信息用于指示一个或多个多播业务待开始，或者，指示一组或多组多播业务待开始，或者，指示是否需要用户设备进入连接态接收多播业务。
其中，网络侧设备执行步骤201，发送该第一指示信息，以使用户设备接收后，在该第一指示信息指示一个或多个多播业务待开始的情况下，直接加入多播业务组，无需接收寻呼消息；在该第一指示信息指示一组或多组多播业务待开始的情况下或者在其指示用户设备进入连接态接收多播业务的情况下，再接收寻呼消息，根据寻呼消息来判断是否加入多播业务组或者是否进入连接态接收多播业务。这样，用户设备可以减少因接收寻呼消息而造成的不必要的功耗。
在一实施例中，所述第一指示信息可以包括N1个比特的信息，每个比特对应一个或一组多播业务，其中N1为正整数。
在一实施例中，所述发送第一指示信息之前，该方法还可以包括：

其中，所述第二指示信息包括第一对应关系，所述第一对应关系包含所述每个比特与一个或一组多播业务的对应关系。
在一实施例中，所述第二指示信息还可以包括第一有效周期，所述第 一有效周期为所述第一对应关系的有效周期。

在一实施例中，所述发送第一指示信息之前，该方法还可以包括：

上述范例性实施例是参考该些附图来描述的，许多不同的形式和实施例是可行而不偏离本申请精神及教示，因此，本申请不应被建构成为在此所提出范例性实施例的限制。更确切地说，这些范例性实施例被提供以使得本申请会是完善又完整，且会将本申请范围传达给那些熟知此项技术的人士。在该些图式中，组件尺寸及相对尺寸也许基于清晰起见而被夸大。在此所使用的术语只是基于描述特定范例性实施例目的，并无意成为限制用。如在此所使用地，除非该内文清楚地另有所指，否则该单数形式“一”、“一个”和“该”是意欲将该些多个形式也纳入。会进一步了解到该些术语“包含”及/或“包括”在使用于本说明书时，表示所述特征、整数、步骤、操作、构件及/或组件的存在，但不排除一或更多其它特征、整数、步骤、操作、构件、组件及/或其族群的存在或增加。除非另有所示，陈述时，一值范围包含该范围的上下限及其间的任何子范围。
以上所述是本申请的一些实施方式，应当指出，对于本技术领域的普 通技术人员来说，在不脱离本申请所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
