Description

一种业务处理的方法、装置和系统 技术领域
本申请涉及通信技术领域,尤其涉及一种业务处理的方法、装置及系统。
背景技术
在第五代(5th generation,5G)通信系统中,5G局域网(local area network,5GLAN),也称为5G虚拟网络(Virtual Network,5GVN),是第三代合作伙伴项目(3rd generation partnership project,3GPP)定义的5G网络的一个服务,主要应用于家庭通信,企业办公,工厂制造,车联网,电网改造和公安机关等。该5GVN服务能够为一个群组中的两个或者多个终端提供互联网协议(internet protocol,IP)类型或者非IP类型(如以太类型)的私有通信。比如,企业中一个部门中的雇员的办公设备可以组成一个群组,群组内的办公设备互相通信,不在群组内的办公设备之间不能互相通信。
针对该5GLAN服务,第三代合作伙伴计划(3rd generation partnership project,3GPP)提出要支持5GLAN的一对一和一对多通信。具体的,要支持5GLAN的一对一和一对多通信,要求3GPP网络支持基于群组的单播、组播和广播;支持对组播和广播报文进行复制分发;以及支持任意终端作为组播源。
当前3GPP 23.501定义了一个5G VN仅有一个会话管理功能(Session Management Function,SMF)网元管理,该SMF网元同时管理一个或多个用户面功能(User Plane Function,UPF)网元。一个5GVN下所有SMF网元之间的业务逻辑由一个组业务管理功能(Group Service Management Function,GSMF)网元协调或管理。
但是,在实际组网中,网络中可能不止一个GSMF网元,这种情况下就需要解决在有多个GSMF网元的网络中的业务处理问题。

如图1所示,本申请实施例提供一种业务处理系统10,该系统10包括:能力开放网元101和第一业务管理设备102。能力开放网元101和第一业务管理设备102之间可以直接通信,也可以通过其他设备的转发进行通信,本申请实施例对此不作具体限定。

具体实现中,如果第一业务管理设备102和用户数据管理设备105集成(或者说合设)在一起,那么第一业务管理设备102就不用发送第三消息,而是由第一业务管理设备102在所述终端标识对应的终端的签约数据中增加所述第一虚拟网络标识。
如图2所示,本申请实施例提供另一种业务处理系统20,该系统20包括:会话管理网元201和第一业务管理设备202。会话管理网元201和第一业务管理设备202之间可以直接通信,也可以通过其他设备的转发进行通信,本申请实施例对此不作具体限定。
一种可能的实现方式中,会话管理网元201,用于接收来自终端的会话建立请求消息,所述会话建立请求消息中携带所述终端的终端标识;会话管理网元201,用于从用户数据管理设备中获取所述终端所在的第一虚拟网络的第一虚拟网络标识;根据所述第一虚拟网络标识确定服务所述第一虚拟网络的第一业务管理设备;向所述第一业务管理设备202发送通知消息,所述通知消息携带所述终端标识和所述第一虚拟网络标识,用于通知所述第一业务管理设备所述终端加入所述第一虚拟网络。通过该方案,可以实现在有多个GSMF的网络中,会话管理网元201也可以寻址到为终端服务的第一业务管理设备,从而将终端上线的消息通知到第一业务管理设备202。

其中,上述方案的具体实现将在后续方法实施例部分详细阐述,在此不再赘述。
图1和图2所示的系统可以用在图3所示的5G网络架构中,当然,也可以用在未来网络架构,比如6G网络架构等,本申请不做限定。
下面以图3所示5G网络架构为例来进行说明。其中,能力开放网元101对应5G中的网络开放功能(network exposure function,NEF)网元,网络存储功能网元103对应5G中的网络存储功能(Network Repository Function,NRF)网元,用户数据仓库104对应5G中的统一数据库(unified data repository,UDR)网元,会话管理网元对应5G中的会话管理功能(session management function,SMF)网元,用户数据管理设备对应5G中的统一数据管理(Unified Data Manager,UDM)网元,应用功能网元对应5G中的应用功能(application function,AF)网元。
如图3所示,该5G网络架构中还可以包括用户面功能(user plane function,UPF)网元,本申请实施例对此不作具体限定。
其中,终端设备通过下一代网络(next generation,N)1接口(简称N1)与AMF网元通信,无线接入网(radio access network,RAN)设备通过N2接口(简称N2)与AMF网元通信,RAN设备通过N3接口(简称N3)与UPF网元通信,UPF网元通过N6接口(简称N6)与DN通信,AMF网元通过N11接口(简称N11)与SMF网元通信,AMF网元通过N8接口(简称N8)与UDM网元通信,SMF网元通过N4接口(简称N4)与UPF网元通信,SMF网元通过N10接口(简称N10)与UDM网元通信,UPF网元与UPF网元通过N9接口(简称N9)进行通信。
此外,需要说明的是,图4所示的5G网络架构中的AMF网元、NRF网元、NEF网元、AF网元、SMF网元、或者UDM网元等网元也可以采用服务化接口进行交互。比如,如图4所示,AMF网元对外提供的服务化接口可以为Namf;NRF网元对外提供的服务化接口可以为Nnrf;NEF网元对外提供的服务化接口可以为Nnef;AF网元对外提供的服务化接口可以为Naf;SMF网元对外提供的服务化接口可以为Nsmf;UDM网元对外提供的服务化接口可以为Nudm。相关描述可以参考23.501标准中的5G系统架构(5G system architecture),在此不予赘述。
其中,业务管理设备在5G中对应GSMF网元,GSMF网元也可以称为5GVN控制器(5GVN controller),名字不做限定。本申请中以GSMF网元为例来进行说明。GSMF可以单独部署,也可以集成或合设在UDR网元、UDM网元或SMF网元中,当然也不限于这些网元。图3和图4中以GSMF网元单独部署为例,其他场景未示出。图4中,以GSMF对外提供的服务化接口为Ngsmf为例,当然这个接口名字后续也可以为其他名字,这里不做限定。
其中,虚拟网络标识在5G中可以就是用来表示5GVN的标识,简称为5GVN标识(Identity,ID),有时也可以称为5G Identifier。5GVN ID可以用来标识一个5GVN。
其中,GSMF网元负责全局管理整个5GVN的信息,包含各个成员(即网络中各个终端设备)所在的SMF,和/或,负责全局管理某个5GVN的各个成员的路由信息,比如各个成员所在的UPF的信息。这里的UDR网元用于保存5GVN的配置信息,比如5GVN成员信息等;还可以保存第三方通过NEF网元定义的5GVN内容。GSMF网元可以调用UDR网元存储的5GVN内容。
当GSMF网元和UDR网元合设时,UDR网元中保存5GVN各个成员的路由信息,GSMF网元负责外部交互;NEF网元对外开放给第三方来定义5GVN,和为5GVN增加或删除成员。UDM网元用来签约成员的5GVN标识。
实际组网中,运营商可以部署多个5GVN网络,一个5GVN网络有时也称为是一个5GVN实例。一个GSMF网元可以管理或服务两个或两个以上的5GVN实例。一个5GVN实例由一个GSMF网元服务。
一个5GVN实例中可以有一个SMF网元或实例,该SMF网元同时管理单个或者多个UPF网元,在UPF网元上配置对应的转发规则。以UE1和UE2之间一对一通信为例,若UE1和UE2都由相同的UPF网元,比如由UPF1网元服务,则通过该UPF local switch方式传输。以UE2和UE3之间一对一通信为例,若UE2和UE3由不同的UPF网元服务,比如UE2由UPF1网元服务,UE3由UPF2网元服务,则UE1和UE3之间需通过UPF1网元和UPF2网元之间的隧道传输。但SMF网元的服务区域是有限的,若5GVN覆盖范围较大,比如某公司在北京和深圳都有分部,两个分部都属于这个5GVN,北京分部由SMF1网元管理,深圳分部由SMF2网元管理,为了简化控制面的处理,则SMF1网元和SMF2网元可以由一个GSMF网元管理。一个SMF网元也可以由多个GSMF网元服务。
在具体实现中,本申请实施例中的终端设备,可以是用于实现无线通信功能的设备,例如终端或者可用于终端中的芯片等。其中,终端可以是5G网络或者未来演进的PLMN中的用户设备(user equipment,UE)、接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、终端代理或终端装置等。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、个人数字助理(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、车载设备或可穿戴设备,虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。终端可以是移动的,也可以是固定的。
在具体实现中,本申请实施例中的能力开放网元、业务管理设备或者会话管理网元的相关功能可以由一个设备实现,也可以由多个设备共同实现,还可以是由一个设备内的一个或多个功能模块实现,本申请实施例对此不作具体限定。可以理解的是,上述功能既可以是硬件设备中的网络元件,也可以是在专用硬件上运行的软件功能,或者是硬件与软件的结合,或者是平台(例如,云平台)上实例化的虚拟化功能。
例如,本申请实施例中的能力开放网元、业务管理设备或者会话管理网元的相关功能可以通过图5中的通信设备500来实现。图5所示为本申请实施例提供的通信设备500的 结构示意图。该通信设备500包括一个或多个处理器501,通信线路502,以及至少一个通信接口(图5中仅是示例性的以包括通信接口504,以及一个处理器501为例进行说明),可选的还可以包括存储器503。
处理器501可以是一个通用中央处理器(central processing unit,CPU),微处理器,特定应用集成电路(application-specific integrated circuit,ASIC),或一个或多个用于控制本申请方案程序执行的集成电路。

图9提供了另一种业务处理方法流程示意图。
S901-S905,同S801-S805。
S907,SMF从5GVN ID中获取GSMF1的标识信息。
具体的,同图1所示实施例中的描述,5GVN ID中嵌入了GSMF1的标识,因此,SMF按照编码规则从5GVN ID中就可以获取到GSMF1的标识信息。

其中,上述步骤S901-S911中SMF网元的动作可以由图5所示的通信设备500中的处理器501调用存储器503中存储的应用程序代码来执行,本实施例对此不作任何限制。
作为一种实现方式,在图6、图7、图8或图9所示的实施例基础上,也可以再包括一个定义新的5GVN的流程。当然,该定义新的5GVN的流程也可以独立存在。下面结合图10来进行说明。
S1001,AF网元发送请求消息给NEF网元,NEF网元接收该请求消息。该请求消息用于新增虚拟网络5GVN1,也可以说是新增虚拟网络请求消息。该请求消息携带该新增5GVN1对应的DNN和S-NSSAI信息,可选的,还可以携带成员列表。
S1003,NEF网元从NRF网元获取GSMF信息。
具体的,NEF网元在接收到DNN和S-NSSAI后,无法根据DNN获知哪个GSMF实例服务该5GVN1,则NEF网元向NRF网元发送DNN和S-NSSAI信息,NRF网元接收该DNN和S-NSSAI消息。NRF网元将与DNN+S-NSSAI对应的所有GSMF实例列表发给NEF。其中,GSMF实例列表中包括GSMF1。然后,NEF网元从中随机选择,或按一定策略选择GSMF1网元作为为5GVN1服务的GSMF网元。
在具体实现中,NRF网元也可能从与DNN+S-NSSAI对应的所有GSMF实例列表中选择出GSMF1,然后将GSMF1的标识信息发送给NEF网元。
S1005,NEF网元发送DNN和S-NSSAI给GSMF1网元,GSMF1网元接收该DNN和S-NSSAI。
S1007,GSMF1网元根据DNN和S-NSSAI分配5GVN1ID。
作为一种实现方式,GSMF1分配5GVN1ID时,可以将GSMF1的标识嵌入到5GVN1ID中,这样后续就可以根据5GVN1ID找到GSMF1。可选的,可以根据一定的编码规则来嵌入。
S1009,GSMF1网元通过NEF将该5GVN1ID发送给AF网元。
具体的,GSMF1网元发送5GVN1ID给NEF网元,NEF网元发送响应消息给AF网元。AF网元收到5GVN1ID后,后续对于同一个5GVN,AF网元就用该ID来交互。
可选的,NEF可以是将GSMF1网元发送的内容转发给AF网元;也可以是将GSMF1网元发送的内容转变消息格式后发给AF网元;也可以是将其中的5GVN1ID以这两种方式发给AF网元。
作为一种实现方式,NEF网元从GSMF1网元收到的虚拟网标识和发给AF网元的虚拟网标识不同,但是这两个标识都是可以标识同一个虚拟网。可选的,NEF网元中可以保存这两个虚拟网络标识的对应关系。比如:这两个虚拟网络标识分别为标识A和标识B,都用来标识虚拟网络1。其中,NEF网元从GSMF1网元接收到的是标识A,发给AF的是标识B。当后续AF网元使用标识B来进行业务时,NEF网元收到AF网元发送的标识B,根据保存的标识A和标识B之间的对应关系,得到与标识B对应的标识A,然后NEF网元使用标识A与网络中的GSMF网元、NRF网元或UDR网元来交互。如果是这种实现方式,那么图6或图7中,AF网元向NEF网元发送的消息中携带的5GVN标识,在经过NEF时,NEF就会将其转化为5GVN标识的另一种形式,然后使用转化后的5GVN标识与NRF等网 元交互。具体这里不再详述。
可选的,图10所示的实施例还可以包括S1101,GSMF1网元发送DNN、S-NSSAI和5GVN1ID给UDR网元,UDR网元接收这三个参数。可选的,UDR网元还可以将这三个参数保存下来。
其中,S1009和S1011无先后顺序之分,可以先执行S1009,再执行S1011;也可以先执行S1011,再执行S1009。
基于本实施例提供的业务处理方法,可以定义一个新的5GVN。通过将新的5GVN ID发给AF,后续可以通过该5GVN实现网络内终端之间的通信。
其中,上述步骤S1001-S1011中NEF网元或GSMF1网元的动作可以由图5所示的通信设备500中的处理器501调用存储器503中存储的应用程序代码来执行,本实施例对此不作任何限制。
