具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在5G NR系统中，MBS业务标识包括以下至少一种：
临时移动组标识(Temporary Mobile Group Identity，TMGI)；
MBS会话标识(Multicast Broadcast Service Session IDentity，MBS Session ID)；
MBS业务流标识(Multicast Broadcast Service Quality of Service flow IDentity，MBS QoS flow ID)。
其中，MBS的发送模式包括以下两种：
·模式1(组播发送)：终端进入RRC连接态，接收MBS的接收配置信息，基于上述接收配置信息接收MBS。其中，上述MBS的接收配置信息是由网络设备通过专属信令发送至终端。
·模式2(广播发送)：终端在RRC连接态、或RRC非激活态、或RRC空闲态(即RRC_idle态)下，接收MBS的接收配置信息，基于上述接收配置信息接收MBS。其中，上述接收配置信息是由网络设备通过系统信息或者MBS控制信道信息发送至终端。示例性的，上述系统信息包括系统信息块(System  Information Block，SIB)；上述MBS控制信道包括主控制信道(Main Control Channel，MCCH)。
如图1所示，展示了组播会话状态和状态转换流程。其中，组播会话状态包括以下三种：
·Configured state(配置态)：对于组播会话，5G核心网的网络功能(5G Core Network Functions，5GC NFs)中提供了组播会话的信息，比如服务质量(Quality of Service，QoS)信息；保留了核心网侧资源，比如组播广播-会话管理功能(Multicast Broadcast-Session Management Function，MB-SMF)、网络业务呈现功能(Network Exposure Function，NEF)和组播广播-用户面功能(Multicast Broadcast-User Plane Function，MB-UPF)的资源；但没有为5G接入网(Next Generation-Radio Access Network，NG-RAN)预留用户面资源，无法传输MBS数据。可以为组播会话分配TMGI；终端经过授权认证和配置后可以被允许加入这一组播会话，第一个被接受的终端的加入请求将触发对NG-RAN和终端的组播会话的建立。
·Activestate(激活态)：组播会话建立，将MBS数据传输到加入组播会话的终端上。组播会话的无线资源建立。为了接收组播的MBS数据，加入该组播会话的终端应处于连接管理-连接(Connection Management-CONNECTED，CM-CONNECTED)态。允许终端加入组播会话(需经过授权)。组播会话的5GC资源和无线资源被预留给加入组播会话的终端。
·Inactive state(非激活态)：组播会话建立，但加入该组播会话的终端上没有MBS数据。组播会话的无线资源被释放，加入该组播会话的终端可能处于CM-CONNECTED或连接管理-空闲(Connection Management-IDLE，CM-IDLE)态。允许终端在经过授权认证后加入组播会话。
101：Multicast Session Activation(组播会话激活)
由5GC触发，组播会话的无线资源建立，组播会话数据(包括MBS数据)开始传输到终端。通知加入组播会话的终端中状态为CM-IDLE和RRC非激活态下CM-CONNECTED的终端。激活可以由应用功能(Application Function，AF)请求或MB-UPF的数据通知触发。组播会话状态由非激活态转换为激活态。
特别的，对于组播会话是处于创建(Creation)状态还是建立(Establishment)状态，AF和NEC都不会感知。因此，AF可以更新会话状态，在会话建立之前请求激活会话，后续当第一个UE加入时，会话随后以激活态建立，但不会触发组播会话激活态转换。
102：Multicast Session Deactivation(组播会话去激活)
5GC触发后，组播会话的无线资源被释放，组播会话数据停止传输到终端。去激活(Deactivation)可以由AF请求触发，也可以由MB-UPF不接收组播数据触发。组播会话状态由激活态转换为非激活态。
103：Multicast Session Release(组播会话释放)
由最后一个终端离开组播会话或组播会话删除过程触发，组播会话的资源在5GC节点和无线接入网络(RadioAccessNetwork，RAN)节点上都被释放。组播会话状态由激活态或非激活态转换为配置态。
104：Multicast Session Deletion(组播会话删除)
所有关于组播会话的信息将从5GC中删除，组播会话的TMGI(如果在组播会话配置期间分配)将被释放。删除可能由AF请求触发。组播会话状态从配置态、或激活态、或非激活态转换为“结束(NULL)”。
其中，5G是第五代移动通信技术(5th Generation Mobile Communication Technology)；NR是新空口(New Radio)。
在3GPP的Rel-17中，支持终端在RRC连接态下的组播业务接收。终端必须先建立RRC连接，在进入RRC连接态后，才能够执行组播业务的接收。这一组播业务的接收方式，无法满足一些关键业务的接收需求，比如MPS。而且终端总是保持RRC连接态以进行组播业务接收，会导致很大的功耗。
因此，在3GPP的第18版(Release 18，Rel-18)中研究支持终端在RRC非激活态(即RRC_inactive态)下的组播业务接收。为了支持终端在移动过程中对组播业务的连续性接收，本公开提供了非激活态组播业务区域的确定方法、以及配置方法，详细实现细节请参考如下实施例。
图2示出了本公开一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网22、用户终端24和核心网设备26。
接入网22中包括若干个接入网设备220。接入网设备220可以是基站，所述基站是一种部署在接入网中用以为用户终端(简称为“终端”)24提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在长期演进(Long Term Evolution，LTE)系统中，称为eNodeB或者eNB；在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基 站”这一描述可能会变化。
核心网中包括若干个核心网设备26。核心网的功能是负责信息在系统内部的交换、路由、用户数据管理、安全等以及与其他通信系统的信息交换传输。5GC的主要网络功能包括：接入和移动性管理功能(Access and Mobility management Function，AMF)、会话管理功能(Session Management Function，SMF)、用户面功能(User Plane Function，UPF)、网络存储库功能(Network Repository Function，NRF)、网络公开功能(Network Exposure Function，NEF)、统一数据管理(Unified Data Management，UDM)、位置管理功能(Location Management Function，LMF)、以及其它网络功能。
为方便本公开实施例中的描述，上述为用户终端24提供无线通信功能的装置统称为网络设备。示例性的，网络设备包括接入网设备220和核心网设备26中的至少一种。
用户终端24可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为用户终端。接入网设备220与用户终端24之间通过某种空口技术互相通信，例如Uu接口。
本公开实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long Term Evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum，LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着 通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及车联网(Vehicle to Everything，V2X)系统等。本公开实施例也可以应用于这些通信系统。
图3示出了本公开一个示例性实施例提供的非激活态组播业务区域的确定方法的流程图，上述非激活态组播业务区域的确定方法应用于如上所述的通信场景中，由终端执行，该方法包括：
步骤301，确定非激活态组播业务的业务区域。
上述非激活态组播业务是指非激活态终端支持的组播业务。上述非激活态组播业务的业务区域是指终端接收非激活态组播业务的区域。

可选地，非激活态组播业务的业务区域根据以下至少一项确定：

也即，终端在连接态时配置有的组播业务的第二业务区域。
