Abstract

本申请实施例公开了一种通信方法、终端设备和网络设备，涉及通信领域，解决了由于DRX周期过长导致的业务传输的时延较长，无法满足业务传输要求的问题。具体方案为: 接收第一消息，该第一消息包括第一DRX配置，该第一DRX配置是与第一MBS对应的DRX配置。根据该第一DRX配置，确定第一DRX周期。根据该第一DRX周期对该第一MBS的第一通知信息进行监听。其中，该第一MBS是终端设备感兴趣和/或正在接收的业务。

Description

一种通信方法、终端设备和网络设备 技术领域
本申请实施例涉及通信领域，尤其涉及一种通信方法、终端设备和网络设备。
背景技术
目前，网络设备可以向终端设备提供组播广播业务(multicast broadcast service，MBS)服务。网络设备可以通过MBS服务向终端设备提供诸如现场直播、定时播放节目等服务。
在MBS业务发生变更时，网络设备需要将该变更的情况告知终端设备，比如，向终端设备发送通知信息，以便终端设备可以根据变更后的MBS的配置进行业务数据的接收。
对于配置了DRX的终端设备而言，可以按照DRX的状态对网络设备发送的信息进行监听，比如，终端设备可以在DRX的状态处于激活态时，进行信息的监听，而在DRX的状态处于睡眠态时，不进行信息的监听。由此节省终端设备的功耗开销。也就是说，在终端设备对网络发送的信息进行监听时，可以接收到网络设备发送的消息。需要说明的是，在不同场景下，终端设备的监听周期长短可能不同。
这样，对于一些传输质量要求较高(如低时延)的MBS，如果终端设备采用较长的监听周期进行监听，可能造成业务传输的时延较长，无法满足业务传输要求。
发明内容
本申请实施例提供一种通信方法、终端设备和网络设备，解决了由于DRX周期(cycle)过长导致的业务传输的时延较长，无法满足业务传输要求的问题。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，提供一种通信方法，该方法包括：接收第一消息，该第一消息包括第一DRX配置，该第一DRX配置是与第一MBS对应的DRX配置。根据该第一DRX配置，确定第一DRX周期。根据该第一DRX周期对该第一MBS的第一通知信息进行监听。其中，该第一MBS是终端设备感兴趣和/或正在接收的业务。
基于该方案，提供了一种监听方案。示例性的，该监听方案可以是终端设备根据与业务对应的DRX进行监听的方案。由于DRX是根据业务(如第一MBS业务)确定的，因此可以避免由于DRX周期过长导致的业务传输(如第一MBS业务)的时延较长，导致无法及时地接收第一通知信息的问题。进而解决无法满足业务传输要求的问题。其中，该第一通知信息可以包括第一MBS的配置信息，比如第一MBS的开始(start)和/或重新开始(restart)等。
在一种可能的设计中，该第一DRX周期为该第一DRX配置对应的DRX周期，以及第二DRX周期中最短的DRX周期，其中，该第二DRX周期包括以下中的至少一项：通过系统信息、非接入层信令、无线资源控制消息获取的DRX配置对应的DRX周期。基于该方案，提供了一种终端设备根据第一DRX配置确定信息监听周期的具体示例。在该示例中，终端设备可以根据第一DRX配置对应的DRX周期，以及为其配置的其他DRX周期中最短的DRX周期(如第一DRX周期)进行信息的监听。可以理解的是，在第一 DRX配置对应的DRX周期为终端设备的所有DRX周期中最短的周期时，那么第一DRX周期与第一DRX配置的周期相同。而在终端设备的其他DRX周期中还存在比第一DRX配置更短的周期时，那么第一DRX周期可以与第一DRX配置的周期不同。这样，终端设备可以采用比第一DRX配置对应的周期更短的周期进行监听，也可以保证MBS的通知信息(如第一通知信息)的及时接收。
在一种可能的设计中，在该接收第一消息之前，该方法还包括：向第一网络设备或第二网络设备发送第二消息，该第二消息用于加入MBS会话(MBS session join)，该MBS会话是该第一MBS的会话。基于该方案，提供了一种终端设备获取第一DRX配置的具体方案示例。在该示例中，终端设备可以通过基于控制面(control plan based，CP-based)MBS session join流程，比如，通过向接入和移动管理功能(Access and Mobility Management Function，AMF)实体发送第二消息，以便于AMF根据该第二消息确定终端设备请求加入与第一MBS对应的会话。AMF根据第一MBS为终端设备配置对应的DRX配置(如第一DRX配置)。在另一种示例中，终端设备还可以通过基于用户面(user plan based，UP-based)MBS session join流程，向用户面功能(user plane function，UPF)实体发送第二消息，以便于UPF根据该第二消息确定终端设备请求加入与第一MBS对应的会话。这样，UPF可以向SMF以及AMF通知终端设备的感兴趣业务为第一MBS，AMF根据第一MBS为终端设备配置对应的DRX配置(如第一DRX配置)。需要说明的是，在本示例中，第一DRX配置可以是核心网中任一个网元确定的，也可以是接入网中确定的。
在一种可能的设计中，该第二网络设备是用户面功能UPF。基于该方案，提供了一种具体的第二网络设备的示例，比如，该第二网络设备可以为UPF实体。
在一种可能的设计中，该方法还包括：在该终端设备不再接收该第一MBS的情况下，向该第一网络设备或第二网络设备发送第三消息，该第三消息用于离开该MBS会话。基于该方案，提供了一种终端设备不再接收第一MBS的情况下的方案示例。其中，终端设备不再接收第一MBS可以包括终端设备不再对第一MBS感兴趣，和/或终端设备停止接收第一MBS，和/或终端设备即将停止接收第一MBS。在该示例中，终端设备可以向核心网设备(如第一网络设备或第二网络设备)发送第三消息，用于请求离开第一MBS对应的会话，以便于核心网设备确定终端设备不再接收第一MBS。可以理解的是，在本示例中，向核心网设备发送第三消息，可以通过UP-based或者CP-based MBS session leave流程实现，也可以通过其他途径发送该第三消息。
在一种可能的设计中，该方法还包括：释放该第一DRX配置。基于该方案，提供了一种终端设备不再接收第一MBS的情况下的方案示例。比如，终端设备可以释放与第一MBS对应的第一DRX配置。可以理解的是，在终端设备释放第一DRX配置之后，可以根据终端设备的其他DRX配置，确定监听信息的DRX周期，比如，将其他DRX配置中对应的最短DRX周期作为监听信息的DRX周期。这样，在第一DRX配置的DRX周期为终端设备所有DRX配置中最短DRX周期时，通过本示例的方案，终端设备重新确定DRX周期，比如，采用更长的DRX周期进行信息的监听，进一步实现节能的效果。在一些实现中，该释放第一DRX配置可以包括删除第一DRX配置。
在一种可能的设计中，在该释放该第一DRX配置之前，该方法还包括：接收来自 该第一网络设备的第四消息，该第四消息用于指示接受离开该MBS会话。基于该方案，提供了一种终端设备释放第一DRX配置的具体方案示例。比如，终端设备可以在接收到第一网络设备(如AMF)发送的接受离开第一MBS会话的第四消息时，释放该第一DRX配置。这样，网络侧对于第一MBS会话的配置与终端设备保持一致。

具体实施方式
为了下述各实施例的描述清楚简洁，首先给出相关概念或技术的简要介绍：
第一，组播广播业务(MBS)。
MBS可以包括在长期演进(Long Term Evolution，LTE)协议框架下的多媒体广播多播业务(Multimedia Broadcast Multicast Service，MBMS)，该MBS还可以包括在5G新空口(new radio，NR)协议框架下的多播广播业务(multicast broadcast service，MBS)。
根据数据传输方式的不同，MBS可以包括组播(multicast)业务以及广播(broadcast)业务。其中，广播业务可以是通过广播进行业务相关信息传输的业务。组播业务可以是通过组播会话(session)实现业务相关信息传输的业务。可以理解的是，组播业务也可称为多播业务。
通过多播(或组播)传输技术，网络设备可以同时面向多个终端设备进行MBS相关信息的传输。示例性的，请参考图1，为一种采用多播传输技术进行的MBS相关信息下发场景下的通信示意图。其中，以网络设备同时向4个终端设备进行MBS相关信息的传输为例。在一些实现中，如图1所示，终端设备可以为用户设备(user equipment，UE)，比如，该4个终端设备可以为UE1，UE2，UE3以及UE4。通过多播传输技术， 网络设备就可以为这4个UE进行MBS相关信息的传输。在本申请实施例中，网络设备可以通过该多播传输技术，向多个终端设备传输MBS的通知信息，在通知信息中可以包括MBS相关的配置。或者，向多个终端设备传输MBS的业务信息等。
在使用多播传输技术进行MBS相关数据的传输时，在一些实现中，以组播业务为例。网络设备可以建立与UE之间的专用承载，比如，网络设备可以建立与UE1之间的承载1，与UE2之间的承载2，与UE3之间的承载3，与UE4之间的承载4。通过这些专用承载(如承载1，承载2，承载3以及承载4)，网络设备就可以将MBS相关信息发送给对应的UE。在本申请实施例中，可以将这种通过专用承载的分别向各个UE发送业务数据的方式称为单播。
在另一些实现中，以广播业务为例。网络设备可以建立覆盖各个UE(如UE1-UE4)的广播用承载，以便通过广播的形式，将MBS相关信息发送给各个UE。
第二，加入MBS会话(MBS session join)。
对于MBS业务感兴趣的终端设备需要首先加入与网络设备的MBS会话，网络设备在需要向终端设备发送MBS相关信息(如MBS的通知信息等)时，通过MBS会话向相应的终端设备发送MBS相关信息。终端设备可以通过基于控制面(control plane based，CP-based)的方式加入MBS会话，还可以通过基于用户面(user plane based，UP-based)的方式加入MBS会话。
示例性的，请参考图2，为一种通过CP-based的方式加入MBS会话的交互流程示意图。其中，以网络设备是AMF，终端设备为UE为例。该流程可以包括：
S201、可选的，UE获取感兴趣的MBS信息(info.of interested MBS)。其中，UE可以从业务服务器获取该MBS信息。该MBS信息也可以是UE已知的。
S202、UE向AMF发送MBS会话加入请求(MBS session join)。
S203、AMF接收MBS会话加入请求，可选的AMF向UE发送MBS会话申请接受。
这样，UE就加入了MBS会话。AMF在需要向UE下发MBS相关信息时，向加入该MBS会话的UE发送相关通知和/或配置信息。
在一些可能的实现中，AMF接受MBS会话加入请求，可以向UE发送消息用于指示接受加入MBS会话(即执行S204)，以便UE知晓已经成功加入MBS会话。
可以理解的是，上述S201-S203示出了终端设备加入MBS会话的一种方案。对应的，在终端设备想要离开MBS会话时，如图2所示，可以执行S205-S206：S205、UE确定不再感兴趣的MBS或者MBS停止。S206、UE向AMF发送MBS会话离开请求。这样，AMF就可以知晓UE不再对该MBS感兴趣(或者，UE已经或即将停止对该MBS的接收)，可选的AMF就不需再将该MBS的相关信息发送给UE。与S204类似的，AMF还可向UE发送消息用于指示接受离开MBS会话(即执行S207)。
上述图2示出了通过CP-based的方式加入MBS会话的示例，以下结合图3对通过UP-based的方式加入MBS会话的过程进行说明。
如图3所示，UE可以向UPF发送MBS会话加入请求(及执行S301)，UPF可以在接收到UE发送的MBS会话加入请求之后，向会话管理功能(session management function，SMF)发送通知1，接着SMF向AMF发送通知2，即执行S302-S303，以便AMF能够知晓UE请求加入MBS会话。这样，在需要向UE发送MBS相关信息时，就可 以基于该UE加入的MBS会话，向UE发送对应的信息。与图2中的说明类似，在UE不再对MBS感兴趣或者MBS停止的情况下，UE可以向UPF发送MBS会话离开请求(如执行S304)，UPF可以通过通知3告知SMF，SMF还可以通过通知4告知AMF(如执行S305-S306)。这样就可以在需要向UE下发MBS相关信息时(比如MBS配置出现变化时)，不再继续向UE发送该信息。
需要说明的是，通过执行上述图2以及图3的方案，终端设备可以加入MBS会话(或称为UE向网络的注册)，进而基于该MBS会话接收MBS相关信息。一般而言，在终端设备向AMF发送MBS会话加入请求，或者在向UPF发送MBS会话加入请求时，还可以向对应的核心网设备(如AMF或UPF)发送终端设备所感兴趣的MBS的标识信息，以便核心网设备可以在有对应的MBS相关信息需要发送时，向该终端设备推送对应的信息。作为一种可能的实现，该MBS的标识信息可以为临时移动组标识(temporary mobile group identity，TMGI)。
第三，非连续接收(discontinuous reception，DRX)。
对于终端设备而言，可以通过向核心网设备请求DRX配置，并根据该DRX配置对应的DRX周期(cycle)进行信息的监听，由此实现节能。其中，一个DRX周期中，可以包括处于激活态(on-duration)的时段以及处于睡眠态(Opportunity for DRX)的时段。终端设备可以在一个DRX周期中，处于on-duration的时段进行信息的监听，而在处于Opportunity for DRX的时段不进行信息的监听，由此节省功耗，达到节能的目的。
作为一种示例，图4为一种终端设备从网络获取DRX配置的流程示意图。如图4所示，终端设备(如UE)可以通过如下方式向核心网设备请求DRX配置：UE可以根据自己的业务需求或者电池情况等，在注册过程中，如首次注册(Initial Registration)或者移动注册(Mobility Registration)流程中，向核心网(Core Network，CN)设备，比如AMF，上报UE想要使用的DRX配置(即执行S401)。AMF可以接收并确认DRX配置(如执行S402)。接着，AMF可以向UE发送注册接受消息(如执行S403)，以便UE可以据此应用DRX配置(如执行S404)，进而根据该DRX配置对应的DRX周期进行监听。
需要说明的是，UE中可能同时配置有多个DRX，那么，UE可以通过这些DRX的DRX周期最短的DRX周期进行监听。示例性的，UE中被配置的DRX可以包括以下中的至少一项：通过系统信息(system information，SI)为UE配置的DRX，通过非接入层(Non-Access Stratum，NAS)信令配置的DRX，以及通过无线资源控制(Radio Resource Control，RRC)消息为UE配置的DRX等。
与UE对应的，网络在触发对于给UE的寻呼(paging)时，也可使用对应的DRX周期向UE进行寻呼，以便UE能够准确快速地监听到该paging。示例性的，核心网设备可以将paging的信息发送给基站，还可将为UE配置的DRX配置下发给基站，以便基站根据该DRX配置，采用对应的DRX周期进行寻呼。
另外，在UE想要向网络请求新的DRX配置时，可以触发移动和定时注册更新(mobility and periodic registration update)，向核心网设备发送基于NAS的消息(比如注册请求(registration request))，在该注册请求中可以包括UE想要使 用的DRX配置。核心网设备(如AMF)则可以通过如图4所示的流程进行类似的处理，以实现向UE的DRX更新。
第四，MBS的通知信息。
可以理解的是，在MBS开始或者变更或者结束时，核心网设备可以触发对应的寻呼机制，以便将MBS相关的配置信息通过寻呼下发给终端设备。在本申请实施例中，可以将该MBS相关的配置信息称为MBS的通知信息。
目前，该MBS的通知信息的寻呼机制可以包括如下两种方案：
方案1：短消息(short message)中包括MBS指示信息，MBS指示信息用于指示此次下发的短消息/下行控制信息(Downlink Control Information，DCI))/MBS的通知信息是否与MBS相关。比如，在DCI中携带有所述MBS指示信息的情况下，可以用于指示该信息与MBS相关。对应的，在DCI中未携带有所述MBS指示信息的情况下，则该信息与MBS无关。
以DCI/短消息中携带有MBS指示信息为例。在终端设备接收到该DCI后，可以通过该DCI携带的MBS指示信息，确定当前寻呼是与MBS业务相关的，如果终端设备对于MBS业务感兴趣，可以读取对应的系统信息块(System Information Block，SIB)或者MBS控制信息(比如承载于组播控制逻辑信道(MBMS Control Channel，MCCH)的信息)等，进而从中获取与MBS相关的具体。比如终端设备通过MBS指示信息确定该通知信息于MBS业务相关后，通过读取SIB/MCCH等获得所述DCI是用于通知某一个或多个MBS业务(比如SIB/MCCH等中携带MBS业务标识，如TMGI)，终端设备确定所述是用于通知某一个或多个MBS业务是否为自己感兴趣的MBS业务(比如通过MBS业务标识确定)。
方案2：在寻呼消息(paging message)中携带MBS相关的信息或者指示。在该方案中，UE在收到寻呼DCI之后，进一步接收后续的寻呼消息。根据该寻呼消息中携带的MBS相关的信息或者指示(比如TMGI)，终端设备就可以知晓当前寻呼是否与MBS相关，和/或当前寻呼消息与某一个或几个MBS相关。比如，在寻呼消息中携带有MBS相关的信息或指示时，例如MBS相关的信息或指示可以是MBS业务标识，如TMGI。终端设备确定所述是用于通知某一个或多个MBS业务是否为自己感兴趣的MBS业务(比如通过MBS业务标识确定)，终端设备就可以确定当前寻呼与MBS相关。对应的，在寻呼消息中未携带MBS相关的信息或指示时，则终端设备就可以确定当前寻呼与MBS不相关。
可以理解的是，应用上述方案1或这方案2，终端设备就可以知晓当前寻呼是否与MBS相关，在确定当前寻呼与MBS相关的情况下，终端设备就可以根据该寻呼下发的通知信息，进行MBS的配置，比如，确定MBS开始或者变更或者结束。
在终端设备配置了DRX的情况，终端设备对于MBS通知信息的监听根据DRX进行的。而如果DRX周期较长，那么对于MBS的信息接收可能出现较大的时延。这对于传输质量要求(比如时延)需求较高的MBS，较大的时延会降低此类业务的传输质量，无法满足传输要求。
为了解决上述由于DRX周期较长导致MBS的传输出现较大时延而无法满足业务传输要求的问题，本申请实施例提供的通信方法，根据MBS传输要求配置相应的DRX周 期，终端设备根据DRX周期对MBS的通知信息进行监听，从而避免因DRX周期过长造成业务传输延时而无法满足业务传输要求。

请参考图5，为本申请实施例提供的一种通信架构500的示意图。
如图5所示，该通信架构500可以包括终端设备510，接入网设备520，以及核心网设备530。在一些实现中，该通信架构500还可以包括业务服务器540。
在该示例中，业务服务器540可以是非第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)框架中的服务器。需要说明的是，在本申请的另一些实现中，也可以通过其他设备实现业务服务器540对应的功能。比如，具有业务处理能力的通信节点，具有业务服务器540相关功能的服务器等。
终端设备510可以是用户设备(user equipment，UE)、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、终端、无线通信设备、多媒体设备、流媒体设备、UE代理或UE装置等。其中的接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的终端等。
需要说明的是，图5是以该通信架构500中包括1个终端设备510为例进行说明的。在另一些实现中，在该通信架构500中还可以包括更多的终端设备510。本申请 实施例对于终端设备510的数量不做限制。
接入网设备520是能和终端设备510进行通信的设备，可以是基站、中继站或接入点。基站可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的节点基站(nodebase station，NB)，还可以是长期演进(long term evolution，LTE)中的演进型(evolutional)NB(eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，还可以是未来5G或者6G网络中的基站设备或者未来演进的PLMN网络中的接入网设备520，还可以是可穿戴设备或车载设备。
核心网设备530可以为实现核心网功能的设备。在不同的实现中，该核心网设备530可以对应不同的一个或多个设备。比如在3G中可以对应通用分组无线服务技术(general packet radio service，GPRS)的服务支持节点(serving GPRS support node，SGSN)和/或GPRS的网关支持节点(gateway GPRS Support Node，GGSN)；在4G中可以对应移动管理实体(mobility management entity，MME)和/或服务网关(serving gateway，S-GW)；在5G中可以对应AMF，SMF和/或UPF。在本申请实施例中，核心网设备530可以用于通过多播传输技术向各个终端设备510提供MBS中的组播业务和/或广播业务。可以理解的是，在该通信系统中，一个或多个核心网设备530可以构成核心网，以提供对应的功能。
作为一种示例，图6示出了核心网的一种组成示意图。如图6所示，核心网可以包括AMF 531，SMF 532，以及UPF 533。其中，该AMF 531主要负责终端设备的接入认证、移动性管理、各个功能网元间的信令交互等工作，如：对用户的注册状态、用户的连接状态、用户注册入网、跟踪区更新、小区切换用户认证和密钥安全等进行管理。该SMF 532主要负责与分离的数据面交互，创建、更新和删除协议数据单元(Protocol Data Unit，PDU)会话，并管理与UPF 533的会话环境(session context)。该UPF可以根据SMF 532发送的信息，与对应的终端设备建立PDU会话，以实现分组路由和转发，数据包检查，用户面部分策略规则实施等功能。
在本申请的不同实现中，AMF 531可以通过NAS信令与终端设备进行交互，也可以通过接入网设备(如基站)与终端设备进行交互。
本申请实施例提供的通信方法，均可应用于如图5所示的通信架构中。为了能够更加清楚地对本申请实施例提供的方案进行说明，以下以终端设备为UE，核心网包括如图6所示的组成为例，对本申请实施例提供的方案进行详细说明。需要说明的是，在本申请实施例中，终端设备感兴趣的MBS，也可以是终端设备正在接收或者即将接收的MBS。对应的，终端设备不再接收的MBS，可以是终端设备不再感兴趣的MBS，也可以是终端设备结束接收的MBS或者即将结束接收的MBS。
请参考图7，为本申请实施例提供的一种通信方法的流程示意图。通过该方案，UE可以根据与MBS匹配的DRX周期进行通知信息的监听，由此避免由于DRX周期过长导致的MBS相关信息传输的时延，进而避免对业务传输要求的影响。如图7所示，该方法可以包括：
S701、UE向业务服务器发送消息1。
在本示例中，UE可以将感兴趣的MBS的信息(如称为UE的兴趣信息)发送给业务服务器。作为一种可能的实现，该UE的兴趣信息可以包括MBS的标识，或者其他能够用于指示该MBS的信息。
示例性的，在UE对第一MBS感兴趣时，可以向业务服务器发送消息1，该消息1可以包括与第一MBS对应的信息。
S702、业务服务器发送第一消息。
其中，该第一消息可以包括与第一MBS对应的DRX配置(如第一DRX配置)。
可以理解的是，在业务服务器接收到消息1之后，就可以通过消息1中携带的兴趣信息，知晓UE感兴趣的MBS。这样，业务服务器就可以将与该MBS对应的DRX配置下发给UE。
示例性的，以UE对第一MBS感兴趣为例。业务服务器可以在接收到消息1之后，向UE发送第一消息，该第一消息中可以包括与第一MBS对应的第一DRX配置，根据该第一DRX配置的DRX周期进行的监听，UE可以快速地接收到MBS相关信息。可以理解的是，在该示例中，业务服务器可以通过广播的形式发送该第一消息。
S703、UE根据第一消息中携带的DRX配置进行通知信息的监听。
示例性的，UE在接收到第一消息之后，可以根据该第一消息中携带的DRX配置(如第一DRX配置)，确定监听通知信息的DRX周期(如第一DRX周期)。
在一种实现方式中，UE可以将该第一DRX配置对应的DRX周期作为监听通知信息的DRX周期。这样，可以保证及时地对第一MBS的通知信息(如第一通知信息)进行监听，由此避免对于第一MBS相关信息的传输时延，进而避免对业务传输要求的影响。
在另一种实现中，UE可以将多个为UE配置的DRX配置中，对应最短的DRX周期作为监听通知信息的DRX周期。应当理解的是，在不同实现中，除了上述第一DRX配置之外，UE还可被配置有其他的DRX配置。示例性的，为UE配置的DRX配置可以包括如下配置中的一个或多个：UE通过系统信息(system information，SI)获取的DRX配置(如称为DRX配置1)；通过NAS信令为UE配置的DRX配置(如称为DRX配置2)；以及通过RRC消息为所述终端设备配置的DRX配置对应的DRX周期(如称为DRX配置3)。
在该示例中，对于空闲态(idle)UE，以UE可以被配置有与第一MBS对应的第一DRX配置，以及上述DRX配置1，和DRX配置2为例。UE可以使用第一DRX配置，DRX配置1以及DRX配置2分别对应的DRX周期中最短的DRX周期，作为第一DRX周期，并根据该第一DRX周期进行通知信息的监听。对于非激活态(inactive)UE，以UE被配置有与第一MBS对应的第一DRX配置，以及上述DRX配置1，DRX配置2和DRX配置3为例。UE可以使用第一DRX配置，DRX配置1，DRX配置2以及DRX配置3分别对应的DRX周期中最短的DRX周期作为第一DRX周期，并根据该第一DRX周期进行通知信息的监听。也就是说，在第一DRX配置对应的DRX周期最短时，则第一DRX周期可以与第一DRX配置对应的周期相同。而在第一DRX配置对应的DRX周期并非对短时，则第一DRX周期可以与第一DRX配置对应的周期不同。
需要说明的是，该第一DRX配置可以是核心网设备确定的，也可以是接入网设备 (如基站)的确定，也可以是应用层确定的，本申请实施例对此不做限制。无论是哪个网元确定的第一DRX配置，都可以将该第一DRX配置通知其他网元，由此，各个网元间对第一MBS的第一DRX配置形成一致的理解。比如，以第一DRX配置是由核心网设备确定为例。那么核心网设备可以将该第一DRX配置通知应用层，应用层可以在UE注册时将此第一DRX配置发送至UE。又如，以第一DRX配置是应用层确定为例。则应用层可以将此第一DRX配置发送至核心网设备。核心网设备在触发第一通知信息时，可以将第一DRX配置发送至基站，以便基站使用多个DRX配置中最短的DRX周期对UE进行通知信息的发送。
在本示例中，UE在根据上述机制接收到第一通知信息之后，可以通过读取SIB或者MCCH或者后续的其他通知信息等方式，获取第一MBS的配置，进而根据该第一MBS配置接收MBS的业务数据。示例性的，结合前述说明，在一些实现方式中，UE可以根据前述方案1的方案，获取第一MBS的配置和/或业务数据。比如，UE可以根据接收到的short message中包括MBS指示信息，其中，MBS指示信息用于指示此次下发的短消息/下行控制信息(Downlink Control Information，DCI))/MBS的通知信息是否与MBS相关，以获取第一MBS的配置以及业务数据。在另一些实现方式中，UE可以根据前述方案1的方案，获取第一MBS的配置和/或业务数据。比如，UE可以根据在寻呼消息(paging message)中携带的MBS相关的信息或者指示，进一步接收后续的寻呼消息。
可以理解的是，相比于目前通知信息的下发和监听机制，采用本申请实施例的方案，对于广播业务感兴趣的UE可以通过向服务器注册(如上述发送消息1)获得业务相应的DRX配置(如第一DRX配置)，避免UE使用的进行通知信息监听的DRX周期过长而带来的业务通知延迟问题。
可以理解的是，上述如图7所示的方案，示出了本申请所述方案在MBS广播/组播业务场景下的一种实现方式。以下结合图8-图10，对本申请的其他实施方式进行示例性说明。
请参考图8，为本申请实施例提供的又一种通信方法的流程示意图。其中，以核心网设备为AMF为例进行说明。如图8所示，该方法可以包括：
S801、可选的，第一UE获取感兴趣的第一MBS的信息。
其中，第一MBS的信息可以是第一UE从业务服务器获取的。比如，第一UE可以在对第一MBS感兴趣时，向服务器发送信息，所述信息可以指示第一UE的兴趣信息，该兴趣信息可以与如图7所示方案中的兴趣信息类似，即该第一UE的兴趣信息可以包括第一MBS的标识，或者其他能够用于指示该第一MBS的信息。可以理解的是，该兴趣信息可以用于通知业务服务器第一UE对于第一MBS感兴趣。对应的，服务器可以在接收到来自第一UE的信息之后，向第一UE发送该第一MBS的信息。第一MBS的信息可以包括以下中的至少一项：QoS要求，时延要求，传输质量要求等。
S802、第一UE向AMF发送第二消息。
在本示例中，第一UE可以在获取第一MBS的信息之后，向AMF发送第二消息。
示例性的，在该第二消息中，可以携带有第一MBS的业务标识，比如该第一MBS的业务标识可以为TMGI。其中，该第一MBS的业务标识可以是在第一UE从服务器获 取第一MBS的信息之后，根据该第一MBS的信息，确定对应的TMGI。
作为一种可能实现，第一UE可以通过如图2所示的通过CP-based的方式加入MBS会话的流程，发送该第二消息。比如，该发送第二消息的过程，可以对应到如图2所示的S202，也就是说，该第二消息可以为MBS会话加入请求。在该场景下，第一UE可以在MBS会话加入请求中携带第一MBS的业务标识，如TMGI，以便于AMF知晓第一UE感兴趣的MBS为第一MBS。
S803、AMF接收第二消息，确定第一DRX配置。
AMF可以根据第二消息，确定第一UE感兴趣的业务为第一MBS。示例性的，AMF可以根据第一MBS的QoS要求等信息，确定第一DRX配置以及相应的周期。
结合S802中的说明，以第二消息为MBS会话加入请求为例。AMF可以根据该第二消息确定第一UE请求加入第一MBS的MBS会话，进而根据第一MBS对应的第一DRX配置，确定接受第一UE使用的DRX配置。
在一些实现中，该AMF接受第一UE使用的DRX配置可以是第一DRX配置。
在另一些实现中，该AMF接受第一UE使用的DRX配置还可以是与第一DRX配置不同的配置。比如，AMF已经向第一UE配置了DRX周期比第一DRX配置对应的DRX周期更短的DRX配置，那么该AMF接受第一UE使用的DRX配置还可以具有更短DRX周期的DRX配置。
以下以AMF接受第一UE使用的DRX配置为第一DRX配置为例。
需要说明的是，该第一DRX配置可以是一组(多个)组播业务对应的DRX，也可以一个组播业务的DRX配置。在一些实现中，以第一DRX配置是一组(多个)组播业务对应的DRX，则这一组播业务可以是核心网根据业务的服务质量流(Quality of Service flow，QoS flow)等参数确定的分组；也可以静态的分组，即根据运营策略等，核心网/运营商/应用层高层确定好的分组等。
S804、AMF向第一UE发送第一消息。
AMF可以将接受第一UE使用的DRX配置通过该第一消息下发给第一UE，以便第一UE可以获取与第一MBS对应的DRX配置。需要说明的是，在本申请的另一些实现中，AMF可以通过接入网设备(如基站)将接受第一UE使用的第一DRX配置下发给第一UE。AMF还可通过NAS信令向第一UE发送该第一消息。
结合上述说明，以第一UE通过CP-based的方式加入MBS会话的流程告知AMF对第一MBS感兴趣为例，那么，在一些实现中，该第一消息可以对应到如图2所示的S204。也就是说，该第一消息可以为接受加入MBS会话的消息。其中，在该接受加入MBS会话的消息中可以携带有第一DRX配置。
S805、第一UE根据第一消息中携带的第一DRX配置进行通知信息的监听。
可以理解都是，第一UE在接收到该第一DRX配置之后，就可以根据该第一DRX配置，进行通知信息的监听。
示例性的，结合上述关于图7中S703的说明，第一UE可以采用为其配置的第一DRX配置，以及其他DRX配置中具有最短DRX周期的DRX配置作为第一DRX配置，进行通知信息(如第一通知信息)的监听。在获取通知信息之后，也可参考上述如图7所示的后续方式(如上述方案1或者方案2)获取第一MBS的其他信息，此处不再赘述。
为了能够更加清楚地对本实施例提供的方案进行说明，以下对AMF通过基站向第一UE下发第一MBS的通知信息的过程进行示例性说明。
继续参考图8，其中的S806-S807示出了该AMF下发第一MBS的通知信息(如第一通知信息)的一种流程示意图。该流程可以包括：
S806、AMF向基站(如gNB)发送第九消息。
在本示例中，当第一MBS(即将)开始时，AMF可以触发通知信息，以便通知加入第一MBS会话(或者对第一MBS感兴趣)的第一UE业务即将开始。示例性的，AMF可以向基站(如gNB)发送第九消息。在一种实现中，该第九消息中可以携带有接收第一MBS的第一UE的标识，比如，该第一UE的标识可以为第一UE ID。在该示例中，该第九消息中还可携带有与第一MBS对应的第一DRX配置，以便于基站根据该第一DRX配置向第一UE发送消息。在一些实现中，该第九消息中还可携带有为第一UE配置的其他DRX配置，比如第一UE specific DRX。
需要说明的是，在本示例的一些实现中，如果第一UE加入多个组播业务，则该第一DRX配置可以是AMF确定的第一UE感兴趣的组播业务中，具有最短DRX周期的DRX配置。
S807、基站向第一UE发送第六消息。
基站可以基于接收到的第九消息，向第一UE发送第一MBS对应的通知信息，即第一通知信息。
示例性的，基站可以根据第九消息中的第一UE的标识信息，和每个第一UE配置的最短DRX(比如第一DRX配置)向相应的第一UE发送通知信息。比如，基站可以向第一UE发送第六消息，在该第六消息中，可以包括有第一通知信息。
可以理解的是，上述S801-S805所述的方案，提供了一种第一UE对第一MBS感兴趣时，从AMF获取第一DRX配置的方案。在本申请的另一种实现中，还提供了在第一UE对第一MBS不再感兴趣(或者不再想接收第一MBS)时的处理机制。
示例性的，如图8所示，在第一UE停止接收第一MBS，即不再对第一MBS感兴趣，或者获得第一MBS结束(或即将结束)的情况下，第一UE可以向AMF发送第三消息，比如，该第三消息可以是MBS会话离开请求。这样，AMF就可以知晓第一UE请求离开第一MBS的会话，由此知晓第一UE停止接收第一MBS。作为一种可能的实现，AMF可以向第一UE回复接受离开MBS会话。
需要说明的是，在一些实现中，AMF可以在接收到第一UE发送的针对第一MBS会话的MBS会话离开请求的情况下，删除此第一UE信息中的第一DRX配置。对应的，第一UE可以在发送MBS会话离开请求后，或者接收到AMF发送的接受离开MBS会话后，删除第一DRX配置，以便能够使用其他DRX配置中最短的DRX配置进行其他信息的监听。
在另一些实现中，AMF还可以向第一UE重新配置与第一UE感兴趣的业务对应的DRX配置，并将该DRX配置下发给第一UE，比如，通过上述接受离开MBS会话的消息(如第四消息)发送给第一UE，以便于第一UE可以根据该新的DRX配置，进行其他信息的监听。
可以理解的是，在本申请的另一些实现中，第一UE也可以在停止接收第一MBS 的情况下，不向网络反馈该变化，如不向AMF发送针对第一MBS会话的MBS会话离开请求，而是直接删除第一UE中存储的第一DRX配置，并根据其他的DRX配置中最短的DRX配置进行信息的监听。这样，第一UE能够对其他信息进行有效地监听的同时，减少第一UE和AMF之间的信令开销。
结合上述针对图8的说明，本领域技术人员应当清楚地了解，通过该方案，第一UE可以根据第一MBS对应的DRX配置进行第一通知信息的监听，由此可以避免对于第一MBS相关信息传输的时延。另外，在该示例中，所有信令都可以结合如图2所示的通过CP-based的方式加入MBS会话的交互过程进行发送，因此不需要为第一UE或网络配置新的传输协议，因此可以最大程度地降低对系统通信的影响。另外，相较于如图4所示的现有技术中网络为第一UE向核心网请求配置DRX配置的过程，第一UE通过注册流程将想要使用的DRX配置发送给核心网，以便于核心网确定该DRX配置，或者为第一UE配置新的DRX配置。本示例中，第一UE在MBS注册流程(MBS session join)向网络上报其感兴趣的业务，如通过第一MBS的会话加入请求告知网络，第一UE对第一MBS感兴趣。网络可以将第一DRX配置发送给第一UE。因此第一DRX的配置是由网络配置的，比如，网络可以根据QoS要求，时延要求，传输质量要求为第一UE配置第一DRX配置。而不需要第一UE将想要使用的DRX配置上报给网络。因此，使用本申请实施例所述方案能够为网络确定DRX提供更好的灵活性。
需要说明的是，本申请实施例还提供一种通信方法，相较于图8所示的方案，可以通过UP-based的方式加入MBS会话的交互过程发送相关信令，实现第一UE可以根据第一MBS对应的DRX配置进行第一通知信息的监听的效果，由此避免由于DRX周期过长导致的传输时延，进而避免由此导致的无法满足业务传输要求的情况发生。
示例性的，该方案的流程图如图9所示：
S901、可选的，第一UE获取感兴趣的第一MBS的信息。
该步骤的执行过程与S801类似，其各种可能均可参考，此处不再赘述。
S902、第一UE向UPF发送第二消息。
结合图3，第一UE可以向UPF发送第二消息，比如MBS会话加入请求。作为一种示例，该请求可以携带第一UE感兴趣的第一MBS的业务标识。
S903、UPF接收第二消息。
该第二消息可以是第一UE向UPF发送的用于请求加入第一MBS会话的消息。
UPF可以根据该第二消息接受第一UE的请求。
S904、UPF向SMF发送消息2。
示例性的，UPF可以通过消息2通知SMF，第一UE请求加入第一MBS。作为一种可能的实现，在该消息2中还可携带有第一UE的标识，比如第一UE ID。在该消息2中还可携带有第一MBS的业务标识，比如第一MBS的session ID等。
S905、SMF向AMF发送第七消息。
SMF在接收到消息2之后，可以通过第七消息通知AMF，第一UE加入第一MBS会话。第一MBS会话与第一MBS对应，或者说，第一MBS会话是第一MBS的会话。在一种可能实现中，以第一MBS上下文不存在/未建立为例，该第七消息还可用于指示AMF向接入网设备(如基站)发送用于建立第一MBS的上下文的消息。在另一种实现中，该第七消息还可 用于指示AMF向接入网设备(如基站)发送建立第一MBS上下文与第一MBS会话之间的关系。
S906、AMF向第一UE发送第一消息。
可选的，AMF通过NAS消息向第一UE发送第一DRX配置；或者，AMF通知基站，基站通知第一UE，以便于第一UE使用第一DRX配置。
示例性的，AMF可以通过NAS消息向第一UE发送第一消息。或者，AMF可以通知gNB，gNB通知第一UE，以便于第一UE接收第一消息。可选的，gNB可以通过广播信息比如SI，MCCH或者dedicated RRC信令向第一UE发送第一消息。
S907、第一UE根据第一DRX配置监听通知信息。
可以理解的是，在第一UE接收到第一消息后，就可以根据第一消息中携带的与第一MBS对应的第一DRX配置，确定第一DRX周期，并据此进行通知消息的监听。其中，第一UE根据第一DRX配置确定第一DRX周期的方法，可以参考上述示例中的方法进行，比如，第一UE可以将为其配置的DRX配置对应的DRX周期中最短的DRX周期确定为第一DRX周期进行信息的监听。
在网络触发第一通知信息的下发的过程如图9中的S908-S909，另外，在第一UE不再接收第一MBS时，可以按照如图9所示的S910-S913所示的流程执行对应的信息交互。其具体过程与图8对应的方案类似，此处不再赘述。
可以理解的是，上述图7，图8以及图9所示的方案，网络可以根据第一UE感兴趣的第一MBS为第一UE配置接受使用的DRX配置，比如第一DRX配置，以便于第一UE可以使用与第一MBS匹配的DRX周期进行通知消息的监听，由此解决由于DRX周期过长导致的无法满足业务传输要求的问题。
本申请实施例还提供一种解决上述技术问题的方案，网络可以根据第一UE上报的与第一MBS匹配的DRX配置，确定接受第一UE使用的DRX配置，并将该接受第一UE使用的DRX配置下发给第一UE，以便第一UE可以使用与第一MBS配置的DRX周期进行通知消息的监听。以下结合图10对该方案进行详细说明。其中以核心网设备为AMF为例，该方案可以包括：
S1001、可选的，第一UE向业务服务器发送消息4。
可以理解的是，该过程的可以参考如图7所示的S701，此处不再赘述。
S1002、可选的，业务服务器向第一UE发送消息5。
业务服务器在接收到消息4后，即可知晓第一UE对第一MBS业务感兴趣。据此，业务服务器就可以将第一MBS的信息发送给第一UE。在一些实现中，第一MBS的信息可以包括第一MBS业务相关信息。比如，该消息5中可以包括第一MBS的业务传输要求，和/或时延要求，和/或QoS要求等。
S1003、第一UE根据第一MBS确定第二DRX配置。
在本示例中，第一UE根据第一MBS信息获取的第一MBS的信息，确定第二DRX配置。该第二DRX配置可以是第一UE想要使用的DRX配置。可选的，第一MBS信息可以是从服务器获取的，比如该第一MBS信息可以包括第一MBS的业务传输要求，和/或时延要求，和/或QoS要求等。
可以理解的是，由于该第二DRX配置是根据第一MBS确定的，因此，如果第一UE使 用该第二DRX配置对应的DRX周期，或者使用比该第二DRX配置对应周期更短的DRX周期进行通知信息的监听，即可避免由于DRX周期过长导致的MBS相关信息(第一通知信息)的传输时延。
作为一种可能的实现，第一UE可以根据第一MBS的信息，以及第一UE的其他业务对DRX周期的要求，和/或电池情况，以及第一UE能力等，确定该第二DRX配置。
S1004、第一UE向AMF发送第五消息。
在本示例中，第一UE可以将根据第一MBS确定的第二DRX配置，发送给AMF，以便于网络可以知晓第一UE对DRX配置的需求。
作为一种示例，结合图4中的说明，第一UE可以通过注册流程，比如Initial Registration或Mobility Registration，向AMF发送第五消息。在该示例中，第五消息可以为注册请求消息。可以理解的是，在该第五消息中，可以携带有第一UE根据第一MBS确定的第二DRX配置。
S1005、AMF根据第二DRX配置确定第一DRX配置。
示例性的，在一种可能的实现中，AMF可以根据第一UE请求的DRX配置(如第二DRX配置)，接受第一UE的请求，即将该第二DRX配置作为接受第一UE使用的DRX配置。即，第一DRX配置为第二DRX配置。
在另一种可能的实现中，AMF可以根据运营策略(operator policy)等因素，以及第一UE请求的DRX配置(如第二DRX配置)，确定第一DRX配置。也就是说，在该示例中，第一DRX配置可以与第二DRX配置不同的配置。
S1006、AMF向第一UE发送第一消息。
AMF确定第一DRX配置之后，就可以通过第一消息将该第一DRX配置发送给第一UE。结合上述S1005的说明，该第一DRX配置可以是根据第二DRX配置确定的。而由于第二DRX配置是第一UE根据第一MBS确定的，因此，该第一DRX配置与第一MBS存在对应关系。也就是说，根据该第一DRX配置进行通知信息的监听，即可避免由于DRX周期过长导致的MBS相关信息传输时延大，从而避免由此导致的无法满足业务传输要求的问题。
作为一种示例，结合图4，AMF可以通过向第一UE发送注册接受消息，该确认消息可以包括第一DRX配置。
S1007、第一UE根据第一DRX配置监听通知信息。
可以理解的是，第一UE在收到第一消息之后，就可以根据该消息中携带的第一DRX配置，进行通知信息(如第一通知信息)的监听。其中，第一UE根据第一DRX配置确定第一DRX周期的方法，可以参考上述示例中的方法进行，比如，第一UE可以将为其配置的DRX配置对应的DRX周期中最短的DRX周期确定为第一DRX周期进行信息的监听。
在网络触发第一通知信息的下发的过程如图10中的S1008-S1009，另外，在第一UE不再接收第一MBS时，可以按照如图10所示的S1010-S1011所示的流程执行对应的信息交互。其具体过程与图8以及图9对应的方案类似，此处不再赘述。
需要说明的是，作为一种可能的实现，在第一UE不再接收第一MBS后，可以触发注册流程，比如mobility registration，或者，第一UE可以在其他原因触发的mobility registration或periodic registration时，向AMF发送新的DRX配置。 对应的，AMF可以根据第一UE请求的DRX配置，接受第一UE的请求，或者根据运营策略等改变第一UE请求的DRX配置，然后将接受第一UE使用的DRX配置下发给第一UE。

请参考图11，为本申请实施例提供的一种通信装置1100的组成示意图。该通信装置1100可以应用于终端设备中。
