多播广播业务的处理方法、装置及计算机可读存储介质
相关申请的交叉引用
本公开要求于2021年07月21日在中国国家知识产权局提交的申请号为CN202110827129.X的中国专利申请的优先权,其全部内容通过引用整体并入本文。
技术领域
本公开涉及无线通信技术领域,具体而言,本公开涉及多播广播业务的处理方法、装置及计算机可读存储介质。
背景技术
对于多播广播业务,UE(User Equipment,用户设备)需要经过授权才能加入多播广播会话,接收该多播广播会话对应的多播广播业务数据。在目前提出的MBS(Multicast Broadcast Service,多播广播业务)的授权信息存储方案中,UE的签约数据(如下表A中所示)和MBS的授权信息(如下表B中所示)都存储在UDM(Unified Data Management,统一数据管理)中。
表A--UE的签约数据
Figure PCTCN2022099250-appb-000001
表B--MBS的授权信息
Figure PCTCN2022099250-appb-000002
Figure PCTCN2022099250-appb-000003
当UE请求加入特定的多播会话时,CN(Core Network,核心网)会话管理功能SMF(Session Management Function)查询UDM中UE的签约数据,判断UE是否被授权加入该多播会话,若是,则继续处理UE的加入请求,将UE加入该多播会话。
然而,UDM接到SMF的UE的约数据请求后,需要查询UE的签约数据(“是否允许接收多播业务数据Multicast allowed”),再进一步根据UE的签约数据查询“多播广播业务(MBS)的授权信息”,才能确定UE是否被授权加入MBS会话。这样导致网络处理UE加入多播会话请求的时间较长,用户体验较差。

具体实施方式
下面详细描述本公开的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,仅用于解释本公开,而不能解释为对本公开的限制。
本技术领域技术人员可以理解,除非特意声明,这里使用的单数形式“一”、“一个”、“所述”和“该”也可包括复数形式。应该进一步理解的是,本公开的说明书中使用的措辞“包括”是指存在所述特征、整数、步骤、操作、元件和/或组件,但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。应该理解,当我们称元件被“连接”或“耦接”到另一元件时,它可以直接连接或耦接到其他元件,或者也可以存在中间元件。此外,这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
本公开实施例中术语“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
为了更好的理解及说明本公开实施例的方案,下面对本公开实施例中所涉及到的一些技术用语进行简单说明。
IP(Internet Protocol,网际互连协议)网络中采用的数据传输方式包括单播、多播与广播。单播(unicast)是指“一对一通信”,即数据由一个设备发送到一个接收设备;而多播/广播(Multicast/Broadcast)是指“一对多通信”,即相同的数据,通过共享信道和内容复制等技术,由一个设备发送到多个接收设备。与单播相比,多播/广播具有更高的网络资源使用效率。
5GS(5G System,第五代移动通信系统)是继4GS(4G System,第四代移动通信系统),即EPS(Evolved Packet System,演进的分组通信系统)后的新一代无线移动通信系统,提供更大的传输带宽、支持更多的终端数目和更多的业务类型。目前5GS支持单播传输。为了支持更多业务,例如IPv4/IPv6多播/广播、IPTV(Internet Protocol Television,交互式网络电视),或优化现有业务(例如:组通信、IoT(Internet ofThings,物联网)通信、V2X(Vehicle to X,车辆网)通信、软件下载/更新等)的传输效率和网络资源使用效率,5GS将支持多播广播业务,即MBS(Multicast Broadcast Service,多播广播业务)。
在5G系统中,UDM(Unified Data Management,统一数据管理)用于管理和存储用户的签约数据(subscription data)。UDM可以本地存储用户的签约数据(若UDM具有本地存储功能),也可以将用户的签约数据存储在UDR(Unified Data Repository,统一数据存储)中。UDR除了用于存储的用户签约数据,还可以存储应用数据(Application data)和策略数据(Policy data)。而UDR可以集中部署,通常UDM采取分散部署。即网络中可能存在多个UDM。那么背景技术中描述的MBS的授权信息,则需要配置/存储在其中一个UDM或所有UDM中。
若MBS的授权信息配置/存储在其中一个UDM(例如UDM-A),则对于某一个UE来说,为其提供服务的UDM(例如UDM-B)中如果没有存储MBS的授权信息,那么该UE在请求加入MBS会话时,UDM-B将因为缺少MBS的授权信息而不允许UE加入MBS会话,进而导致UE加入MBS会话失败。
然而,为了保证UE请求加入的MBS会话不发生失败,提出将MBS的授权信息配置/存储在所有UDM中,这样会造成MBS的授权信息重复存储,同时也增加数据更新的复杂性,例如当MBS业务或MBS会话更新时需要向多个UDM同步更新MBS的授权信息。
下面将结合本公开实施例中的附图,对本公开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公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方 式作进一步地详细描述。
本公开实施例中提供了一种多播广播业务的处理方法,由UDM执行,该方法的流程示意图如图1所示,该方法包括:
步骤S101,向统一数据存储UDR发送第一请求,第一请求用于请求多播广播业务MBS的授权信息。
其中,UDR存储中MBS的授权信息。
在一个实施例中,MBS的授权信息(即MBS authorization data,在一些场景下也可以称之为MBS会话签约数据(MBS session subscription data)、或者MBS签约数据(MBS subscription data))用来表征多播广播业务CP(Content Provider,内容提供者)、AS(Application Server,应用服务器)、AF(Application function,应用功能)或网络授权指定UE能够接收指定的多播广播业务。即通过MBS的授权信息能够判断出哪些UE能够接收哪些多播广播业务,哪些UE不能够接收哪些多播广播业务。
在一个实施例中,MBS的授权信息MBS subscription data表示多播广播业务内容提供者、AS、AF或网络,授权UE接收特定的多播广播业务。MBS的授权信息如表1所示(与背景技术中所记载的表B的内容相同,说明UDR中存储的MBS的授权信息中所包含的字段相对于背景技术中UDM中存储的MBS的授权信息中所包含的字段并没有发生变化)。
表1:MBS的授权信息(MBS subscription data)
Figure PCTCN2022099250-appb-000004
Figure PCTCN2022099250-appb-000005
其中,MBS的授权信息中所包含的依赖位置的多播广播业务信息具体包含的内容可以如表2所示,具体包含区域会话标识和多播广播业务服务区域等。这里的区域会话标识可以理解为也是一种会话标识,不同在于能够根据该区域会话标识确定出在某一个特定区域适用的MBS会话有哪些。
表2:依赖位置的多播广播业务信息
Figure PCTCN2022099250-appb-000006
可选的,在UDR中存储了MBS的授权信息之外,还可以存储MBS的授权信息的关键字,通过该关键字可以对MBS的授权信息进行检索或者查询,以提升数据查询速度。例如:如表3中所示的关键字。
表3:MBS的授权信息的关键字(索引值)
Figure PCTCN2022099250-appb-000007
即通过多播广播业务会话标识能够查询到该MBS会话标识对应的MBS授权信息、依赖位置的MBS信息等;通过区域会话标识能够查询到依赖位置的MBS信息等。
在一个实施例中,第一请求可以为数据管理查询请求或数据管理订阅请求,其中,数据管理查询请求用于请求查询MBS的授权信息,数据管理订阅请求用于请求订阅MBS的授权信息。
具体的,由于UDR中存储MBS的授权信息,UDM可以向UDR发送数据管理订阅请求,通过数据管理订阅请求,UDR可以将UDM订阅的MBS的授权信息周期地或者在满足订阅需求的情况下发送给UDM,以便于UDM及时获取MBS的授权信 息。此外,当UDR中存储的MBS的授权信息发生变化或者更新,UDR可以基于该订阅功能向UDM发送变化的或者更新后的MBS的授权信息。
可选的,UDM还可以根据本地策略向UDR发送数据管理查询请求或数据管理订阅请求,例如:向UDR发送周期性查询请求,或者订阅到期后向UDR发送延续/更新订阅请求等等。
可选的,UDM可以在接收到其他网元发送的处理请求的情况下,确认需要获取MBS授权信息,此时,可以向UDR发送数据管理查询请求,以通过该数据管理查询请求,从UDR中查询MBS授权信息。这里的数据管理查询请求可以查询指定对象的MBS的授权信息,也可以是查询所有对象的MBS的授权信息。
在一个实施例中,在向UDR发送第一请求之前,还包括:
接收会话管理功能SMF发送的第二请求,其中,第二请求携带UE的标识,第二请求用于请求标识对应的UE的MBS的签约信息。
UDM在接收到SMF发送的第二请求时或者之后,可选地,判断本地是否存储有标识对应的UE的MBS的签约信息,如果有,可以直接将存储的UE的MBS的签约信息发送给SMF。如果没有,此时UDM可以向UDR发送第一请求,这里的第一请求可以是数据管理查询请求,该数据管理查询请求中携带UE的标识,即通过该数据管理查询请求,从UDR中查询该UE的MBS的签约信息(即授权信息)。
需要说明的是,这里UDM中已经存储的UE的MBS的签约信息可以是通过订阅事件获取并存储的,也可以是其他方式,这里对于UDM何时通过什么方式获取不做具体限定。
在一个实施例中,UDM在接收到SMF发送的第二请求之后,可以在向UDR发送的第一请求中携带UE的标识,以请求UE的MBS的授权信息(即第二请求所请求的UE的MBS的签约信息)。
在一个实施例中,第二请求可以是签约数据管理获取请求或签约数据管理订阅请求,第二请求用于请求获取或订阅标识对应的UE的MBS的签约信息。
例如,在向UDR发送第一请求之前,UDM接收SMF发送的第二请求,其中,第二请求可以是签约数据管理获取请求或签约数据管理订阅请求,签约数据管理获取请求用于请求获取标识对应的UE的MBS的签约信息,签约数据管理订阅请求用于请求订阅标识对应的UE的MBS的签约信息。
在一个实施例中,UDM在接收到SMF发送的第二请求之后,还包括:如果本地存储有标识对应的UE的MBS的签约信息,则将UE的MBS的签约信息发送给SMF。
可选的,如果UDM通过订阅方式已经从UDR中获取了UE的MBS的签约信息,那么UDM向SMF发送UE的MBS的签约信息。
步骤S102,接收UDR发送的第一响应,第一响应包括请求的MBS的授权信息。
在一个实施例中,第一响应是数据管理查询回复或数据管理通知消息。
例如,UDM接收UDR发送的第一响应,其中,第一响应可以是数据管理查询回复或数据管理通知消息,数据管理查询回复或数据管理通知消息携带MBS的授权信息。如果是针对订阅事件发送的第一响应,那么该第一响应可以为数据管理通知消息,通过该数据管理通知消息通知MBS的授权信息发生变化或者更新,那么第一响应中携带变化后或者更新后的MBS的授权下信息;
如果是针对数据查询请求发送的第一响应,那么该第一响应可以是数据查询回复消息,通过该数据查询回复消息通知UDM查询结果。在一个实施例中,若第一请求携带UE的标识,则接收UDR发送的第一响应,包括:接收UDR发送的携带标识对应的MBS的授权信息的第一响应。即在数据查询回复消息中携带待查询UE的标识对应的MBS的授权信息。
步骤S103,根据请求的MBS的授权信息,对用户设备UE的签约数据进行处理。
下面针对不同的场景,分别描述UDM在接收到UDR反馈的MBS的授权信息之后,如何对UE的签约数据进行处理的。
针对订阅事件,UDM在UDR反馈的变化的或者更新的MBS的授权信息之后,对UE的签约数据进行处理。
根据变化的或者更新的MBS的授权信息,确定所授权使用的UE的标识,针对每一个UE,分别执行以下操作:
根据确定的UE的标识,从UDM中存储的所有UE的签约信息中确定该标识对应的UE的签约信息;
判断确定的UE的签约信息中是否包含有MBS的授权信息;
如果未包含MBS的授权信息,则从变化的或者更新的MBS的授权信息确定出授权该UE使用的MBS的授权信息,并将确定出的MBS的授权信息存储在该UE的签约信息中;
如果包含MBS的授权信息,则从变化的或者更新的MBS的授权信息确定出授权该UE使用的MBS的授权信息,并利用确定出的MBS的授权信息对该UE的签约信息中的MBS的授权信息进行更新。
针对数据查询事件,UDM在UDR反馈数据查询结果之后,对UE的签约数据进行处理。
如果查询结果中包含多个UE的MBS的授权信息,可以参照上述记载的方式进行处理;
如果查询结果中包含请求的UE的MBS的授权信息,那么UDM将接收到的MBS的授权信息存储在该UE的签约信息中。
在一个实施例中,根据请求的MBS的授权信息,对UE的签约数据进行处理,包括:
根据请求的MBS的授权信息,确定UE的MBS的签约信息,将UE的MBS的签约信息存储在UE的签约数据中;或者,
根据请求的MBS的授权信息,更新UE的签约数据中的UE的MBS的签约信息。
在一个实施例中,UE的MBS的签约信息是UE的签约数据中包括的该UE签约的MBS的信息,即与该UE被授权的MBS相关的信息。
在一个实施例中,在UDM中,存储针对每个UE的MBS的签约信息(MBS subscription data per UE),每个UE的MBS的签约信息(如表4所示)包括:该UE可以加入的MBS会话标识(MBS Session ID)(可以采用列表方式呈现)和该UE可以加入的依赖位置的多播广播业务信息Location dependent MBS information(也可以采用列表方式呈现)。

可选地,在UE的MBS的签约信息中还可以包含任意UE都可以加入的MBS会话标识列表MBS Session ID list for any UE、任意UE都可以加入的依赖位置的多播广播业务信息列表List of Location dependent MBS information for any UE等信息。其中,任意UE都可以加入的MBS会话标识列表MBS Session ID list for any UE表示允许任意UE加入的多播会话的标识列表;任意UE都可以加入的依赖位置的多播广播业务信息列表List of Location dependent MBS information for any UE表示允许任意UE加入的依赖位置的多播会话的信息列表。
可选的,在UDM中存储每个UE的MBS的签约信息之外,还可以存储MBS的签约信息的关键字,通过该关键字可以对每个UE的MBS的签约信息进行检索或者查询,以提升数据查询速度。例如:如表5中所示的关键字。
表5:UE的MBS的签约信息的关键字(索引值)
Figure PCTCN2022099250-appb-000009
Figure PCTCN2022099250-appb-000010
在一个实施例中,可以通过一个保留的TMGI值,或者采用一个特殊指示,例如“Any MBS Session allowed”,表示网络允许某个UE加入任意的多播会话。TMGI值可以为0或者1表示。对于网络授权加入任意多播会话的UE,可以在该UE的MBS的签约信息中预先配置能够表示网络允许接入任意多播会话的TMGI值或者特殊指示信息。这样UDM或者SMF通过该TMGI值或者特殊指示信息确定该UE可以加入的多播会话,以此响应UE发送的多播会话业务请求。
在一个实施例中,UE的MBS的签约信息包括以下信息中的至少一种或者多种:
UE被授权加入的MBS会话标识;
UE被授权加入的依赖位置的MBS信息;
用于指示UE被授权加入任意MBS会话的指示信息。
在一个实施例中,如表4所示的MBS会话标识列表包括至少一个UE被授权加入的MBS会话标识,依赖位置的MBS信息列表包括至少一个UE被授权加入的依赖位置的MBS信息。
在一个实施例中,被配置为指示UE被授权加入任意MBS会话的指示信息包括特定取值的临时移动组标识TMGI。
在一个实施例中,由于MBS的授权信息中还包含任意UE都可以加入的MBS会话、任意UE都可以加入的依赖位置的多播广播业务信息等,这些内容对于多个UE来说都可使用,那么这些内容可以存储在每个UE的签约信息中,这样可能导致数据重复存储,因此,可以将这些内容单独进行存储,即单独于UE的签约信息之外,在UDM中独立存储“任意UE的MBS的签约信息MBS subscription data for any UE”中。如表6所示。
表6:任意UE的MBS的签约信息MBS subscription data for any UE
