具体实施方式
本文中术语“和/或”,仅仅是一种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。
本申请实施例的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象,而不是用于描述对象的特定顺序。例如,第一边缘配置服务器和第二边缘配置服务器等是用于区别不同的边缘配置服务器,而不是用于描述边缘配置服务器的特定顺序。
在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中,除非另有说明,“多个”的含义是指两个或两个以上。例如,多个处理单元是指两个或两个以上的处理单元;多个系统是指两个或两个以上的系统。
首先对本申请实施例提供的一种边缘配置服务器的确定方法及装置中涉及的一些概念做解释说明。
公共陆地移动网络(public land mobile network,PLMN):是由政府或政府所批准的经营者,为公众提供陆地移动通信业务目的而建立和经营的网络。应理解,同一经营者可以建立不同的PLMN。
归属公共陆地移动网络(home public land mobile network,HPLMN):可以理解为终端装置签约的PLMN,例如,对于某一个终端装置来说,其签约的PLMN(例如运营商A,则可以认为运营商A的PLMN为该终端装置的HPLMN。并且对于某一使用单SIM卡通信的终端装置来说,其归属的PLMN只有一个,即一个终端装置只有一个HPLMN。
访问公共陆地移动网络(visited public land mobile network,VPLMN):可以理解为终端装置通过归属PLMN之外的有漫游协议的PLMN接入网络,例如,对于某一终端装置来说,假设该终端装置的归属网络为运营商A,该终端装置漫游至其他国家,终端装置通过其它国家的PLMN(例如运营商B)接入网络从而获取业务服务,则其它国家的PLMN为该终端装置的VPLMN。
移动网络运营商(mobile network operator,MNO):PLMN中的移动网络的运营商。例如上述的运营商A和运营商B。
漫游状态:终端装置位于该终端装置的归属网络,终端装置接入的网络为HPLMN,即认为终端装置处于非漫游状态;终端装置位于该终端装置的归属地之外的网络,终端装置接入的网络为VPLMN,即认为该终端装置处于漫游状态。
关于第三代合作伙伴计划(3rd generation partnership project,3GPP)的边缘(EDGE)架构的介绍:
3GPP对多接入移动边缘计算(MEC)的研究中,定义了一种边缘应用架构(可以称为SA6EDGE应用架构),图1为该边缘应用架构的示意图,在该边缘应用架构中,用户设备可以通过核心网从边缘数据网络(edge data network,EDN)获取应用数据,边缘应用架构中的功能实体主要包括应用客户端(即application client(s),AC)、边缘使能客户端(即edge enabler client,EEC)、边缘应用服务器(即edge application server(s),EAS)、边缘使能服务器(edge enabler server(s),EES)以及边缘配置服务器(edge configuration server,ECS)。其中,EDGE-1至EDGE-9为各个功能实体之间的接口。具体的,结合图1,应用客户端和边缘使能客户端部署在用户设备侧或终端装置中,边缘应用服务器和边缘使能服务器部署在边缘数据网络中,边缘配置服务器的部署位置不作限定,例如,ECS可以部署在EDN中,或数据网络(data network,DN)中,或PLMN中。
边缘数据网络EDN:一种对EDN的通用理解是:EDN只对应一个数据网络,EDN是一个特别的本地数据网络(local DN),该本地数据网络具有边缘使能功能,可以使用数据网络接入标识(data network access identity,DNAI)或数据网络名称(data network name,DNN)来标识EDN,此时EDN是逻辑概念的网络。另一种对于EDN的理解是:EDN是中心云的对等概念,可以理解为是一个本地的数据中心,EDN可以包含多个本地数据网络(local DN),可以使用DNAI来标识EDN。
下面对边缘应用架构中的各个功能实体的功能进行介绍。
边缘应用服务器EAS:也可以称为边缘应用、应用实例、边缘应用实例、MEC应用(服务器)、EAS功能等。EAS是部署在边缘数据网络中的应用实例,具体是指一个服务器应用程序(例如,社交媒体软件、增强现实(augmented reality,AR)、虚拟现实(virtual reality,VR))部署运行在EDN的实例(instance)。对于某一个应用,可在一个或多个EDN中部署该应用的EAS,并且可以部署一个或多个EAS,部署运行在不同的EDN中的EAS可以认为是一个应用的不同的EAS,它们可以共享一个域名,可以使用一个相同的IP地址,也可以使用不同的IP地址。
应用客户端AC:是EAS在用户设备侧的对等实体。应用客户端用于用户设备从应用服务器获取应用的业务数据。应用客户端是一个应用在终端装置侧的客户端程序,应用客户端可以连接到云上的应用服务器获取应用的业务数据,也可以连接到部署运行在一个或多个EDN中的EAS以获取应用的业务数据。
边缘使能服务器EES:部署在EDN中,上述EAS可以注册到EES上,EES可以为部署在EDN中的应用实例(EAS)提供一些使能能力。具体的,EES对EAS具有管理控制的能力,同时EES可以向EAS提供3GPP核心网功能,例如EES向EAS提供3GPP用户面事件管理信息等;此外当用户设备侧的应用需要在不同服务器(EAS)上进行迁移时,EES能够提供EAS发现和应用上下文迁移功能。EES可以对用户设备进行认证和鉴权,为用户设备提供应用实例的信息(例如应用实例的标识信息、IP地址信息)。
一般情况下,EAS注册到一个EES上,或者,通过管理系统将一个EAS的信息 配置在一个EES上,该EES称为该EAS关联的EES,EES控制、管理注册、配置在该EES上的EAS。
边缘使能客户端EEC:是EES在用户设备侧的对等实体。EEC可以向EES注册EEC的信息及应用客户端的信息、执行安全认证和鉴权、从EES获取EAS的信息;并且EEC能够向应用客户端提供边缘计算使能能力,如提供EAS发现服务功能,将EAS的IP地址返回给应用客户端。
边缘配置服务器ECS:主要负责EDN的配置。EDN中的EES需要在ECS上进行注册,从而ECS可以向用户设备提供EES的信息,即ECS可以提供EES发现功能。ECS还可以从其他功能实体获取并保存应用实例和IP地址的信息,ECS可以直接向用户设备提供应用实例的信息等。
应理解,基于上述图1所示的边缘应用架构,用户设备从边缘数据网络获取应用数据之前,需要解决边缘配置服务器的发现问题和边缘使能服务器的发现问题。具体的,边缘配置服务器的发现是通过核心网网元与用户设备进行交互,为用户设备确定合适的边缘配置服务器;边缘使能服务器的发现是通过用户设备与上述确定的边缘配置服务器进行交互(执行服务提供流程,即service provisioning流程),为用户设备确定合适的边缘使能服务器,从而用户设备从确定的边缘使能服务器获取边缘应用服务器的信息,如此,用户设备侧的边缘客户端能够从边缘应用服务器获取应用数据。

目前,在3GPP SA2中对边缘配置服务器的发现问题进行研究的过程中,对于用户设备漫游的场景,提出在用户设备与网络建立会话的过程中,会话管理功能网元(即上述5G通信系统中的SMF)可以确定出为用户设备提供服务的边缘配置服务器。
可以理解的是,当终端装置处于漫游状态时,终端装置与网络建立的会话类型可以包括本地分流和归属路由。
本地分流:指的是终端装置处于漫游状态时,终端装置用户面数据可以由本地疏导(local breakout,LBO),即由该终端装置当前的漫游地的PLMN(即VPLMN)的用户面来处理该终端装置的用户面数据(即终端装置的用户面数据由VPLMN路由),终端装置的用户面数据无需回到该终端装置的归属网络(即HPLMN)中。
归属路由(home routed):指的是终端装置处于漫游状态时,终端装置的用户面数据均需回到其归属网络(即HPLMN)中处理,即由HPLMN路由。
以下分别从终端装置与网络建立不同的会话类型的角度简要介绍关于边缘配置服务器的确定方法。
需要说明的是,在以下实施例中所涉及的统一数据管理功能网元表示为UDM,会话管理功能网元表示为SMF,策略控制功能网元表示为PCF,接入和移动管理功能网元表示为AMF,边缘使能客户端表示为EEC,边缘配置服务器表示为ECS,边缘使能服务器表示为EES。
首先,结合图5所示的漫游情况下的网络架构,在终端装置与网络建立的会话类型为本地分流的情况下,可以由VPLMN中的会话管理功能网元确定边缘配置服务器,如图6所示,确定边缘配置服务器的具体过程包括步骤601至步骤607。
步骤601、终端装置发送会话建立请求信息至V-AMF。
步骤602、V-AMF向V-SMF发送创建会话管理上下文请求信息(例如通过发送Nsmf_PDUSession_CreateSMContext Request发送该创建会话管理上下文请求信息)。
上述V-SMF表示VPLMN中的SMF,V-AMF表示VPLMN中的AMF。
可以理解的是,上述创建会话管理上下文请求信息中可以包括用户永久标识(subscription permanent identifier,SUPI),即终端装置的SUPI、选择的DNN、终端装置请求的DNN、S-NSSAI(s)和PDU Session ID,N1 SM container(即会话建立请求)等信元中的至少一种。
步骤603、V-SMF从UDM中获取终端装置的签约信息。
可以理解的是,UDM中的终端装置的签约信息包括终端装置可以访问的ECS的标识信息。可选地,还可以包括会话类型、允许的会话和服务连续(session and service continuity,SSC)模式、缺省的5G服务质量标识(5G QoS identifier,5QI)、分配与预留优先级(allocation and retention priority,ARP)、终端装置签约的会话聚合最大比特率(session aggregate maximum bit rate,即session-AMBR)、SMF相关的外部参数等中的一项或多项。上述UDM为HPLMN中的UDM。
步骤604、UDM向V-SMF发送终端装置的签约信息。
步骤605、V-SMF根据本地配置、终端装置的位置和/或终端装置的签约信息确定支持为终端装置提供服务的ECS。
应理解,上述终端装置的签约信息中的ECS标识信息(即终端装置可以访问的ECS的标识信息)用于确定支持为终端装置提供服务的ECS。
具体的,V-SMF可以根据本地配置和终端装置的位置确定支持为终端装置提供服务的ECS,或者,V-SMF根据本地配置和终端装置的签约信息确定支持为终端装置提供服务的ECS,或者V-SMF根据本地配置、终端装置的位置以及终端装置的签约信息确定支持为终端装置提供服务的ECS,具体根据实际情况确定采用上述信息中的哪几种信息确定ECS,本申请实施例不作限定。
步骤606、V-SMF将支持为终端装置提供服务的ECS的地址信息发送至终端装置。
步骤607、终端装置向支持为终端装置提供服务的一个或多个ECS发起服务提供请求。
在边缘配置服务器的确定中,V-SMF所根据的本地配置、终端装置的位置和/或终端装置的签约信息中,不包括终端装置当前接入的PLMN信息,则会出现所选择的边缘配置服务器虽然能够为终端装置服务,但其只能提供位于其它PLMN中的边缘使能服务器来为终端服务,这样会造成跨PLMN通信,造成过长的数据路径,降低数据传输效率。
其次,结合图7所示的漫游情况下的网络架构,在终端装置与网络建立的会话类型为归属路由的情况下,可以由HPLMN中的会话管理功能网元确定边缘配置服务器,如图8所示,确定边缘配置服务器的具体过程包括步骤801至步骤807。
步骤801、终端装置发送会话建立请求信息至V-AMF。
步骤802、V-AMF通过V-SMF将创建会话管理上下文请求信息(例如通过发送Nsmf_PDUSession_CreateSMContext Request发送该创建会话管理上下文请求信息)发送至H-SMF。
上述V-AMF表示VPLMN中的AMF,V-SMF表示VPLMN中的SMF,H-SMF表示HPLMN中的SMF。
同理,上述创建会话管理上下文请求信息中包括SUPI、选择的DNN、终端装置请求的DNN、S-NSSAI(s)和PDU Session ID,N1 SM container(即会话建立请求)等信元中的至少一种。
步骤803、H-SMF从UDM中获取终端装置的签约信息。
可以理解的是,UDM中的终端装置的签约信息包括终端装置可以访问的ECS的标识信息。可选地,还可以包括会话类型、允许的SSC模式、缺省的5QI、ARP、终端装置签约的会话聚合最大比特率、SMF相关的外部参数以及终端装置可以访问的ECS的标识信息。上述UDM为HPLMN中的UDM。
步骤804、UDM向H-SMF发送终端装置的签约信息。
步骤805、H-SMF根据本地配置、终端装置的位置和/或终端装置的签约信息确定支持为终端装置提供服务的ECS。
步骤806、H-SMF将支持为终端装置提供服务的ECS的地址信息通过V-SMF和V-AMF发送至终端装置。
步骤807、终端装置向支持为终端装置提供服务的一个或多个ECS发起服务提供请求。
综上所述,目前H-SMF确定的支持为终端装置服务的ECS是所有的可以为终端装置提供服务的ECS,当支持为终端装置服务的ECS包括多个时,未提及终端装置基于哪个ECS发起EES发现流程,假设终端装置从多个ECS中任意选择一个ECS,不考虑终端装置当前接入的PLMN信息,则会出现所选择的边缘配置服务器虽然能够为终端装置服务,但其只能提供位于其它PLMN中的边缘使能服务器来为终端服务,这样会造成跨PLMN通信,造成过长的数据路径,降低数据传输效率,终端装置的业务质量无法得到保证;如终端装置向多个ECS中的每个ECS都发起EES发现流程,将造成资源的浪费。
终端装置接收到支持为终端装置提供服务的ECS地址信息之后,终端装置上的EEC根据ECS地址信息向对应的ECS发起服务提供流程。参考图9,一种服务提供流程包括步骤901至步骤906。
步骤901、终端装置向ECS发送服务提供请求信息。
上述服务提供该请求信息中包括但不限于终端装置的位置信息、服务需求、服务偏好和连接性等信息。
示例性的,如下表1所示为服务提供请求信息携带的必选信元和可选信元的示例。

应理解,上述表1中的可选的信息可以是实现不同的功能时携带不同的信息。
步骤902、ECS根据服务提供请求信息中的终端装置的位置信息、服务需求、服务偏好和连接性等信息,确定为终端装置提供服务的EES。
步骤903、ECS向终端装置发送服务提供响应信息,该服务提供响应信息中包括为终端装置提供服务的EES的信息。
示例性的,如下表2所示为服务提供响应信息携带的必选信元和可选信元的示例。

综上,在服务提供流程中,ECS为终端装置选择的EES可能与终端装置当前接入的网络是不同的网络,例如,终端装置当前接入的是一个VPLMN,而ECS为终端装置选择的是HPLMN中的EES,如此,终端装置在漫游状态时,仍需从HPLMN中的EES获取应用数据,将造成信令资源浪费,也就是说,终端装置到EES的路径不是最 优的路径。
本申请实施例提供了一种边缘配置服务器的确定方法,核心网网元根据终端装置接入的移动网络,确定为终端装置服务的边缘配置服务器为第一边缘配置服务器;其中,该第一边缘配置服务器所对应的至少一个移动网络中包括终端装置接入的移动网络;核心网网元向该终端装置发送用于指示第一边缘配置服务器的信息。
在本申请实施例中,是以移动网络为PLMN为例进行说明的,移动网络还可以是其它类型的网络。此外,终端装置接入的移动网络,可以为终端装置当前接入的PLMN,或者理解为正在为所述终端装置服务的PLMN。终端装置接入的PLMN信息在实施例中可以作为第一信息,或者包含在第一信息中。边缘配置服务器信息包括第一边缘配置服务器的标识信息和与所述第一边缘配置服务器对应的所述至少一个移动网络的标识信息,边缘配置服务器信息可以作为第二信息,或者包含在第二信息中,其中标识信息可以是标识或地址信息,也可以是其它可以指示边缘配置服务器信息。第二信息中包含的标识信息是支持为终端装置提供服务的边缘配置服务器的标识信息;与边缘配置服务器对应的所述至少一个移动网络的标识信息,也可以理解为所述边缘配置服务器的标识信息与至少一个移动网络的标识信息相对应。
核心网网元发送的指示第一边缘配置服务器的信息,可以是第一边缘配置服务器的标识信息,例如标识,或者地址信息,或其它能够指示该配置服务器的信息。在本申请的实施例中,以发送第一边缘配置服务器的地址信息为例进行了说明。
本申请实施例提供了另一种边缘配置服务器的确定方法,该方法中,终端装置获取边缘配置服务器信息,所述边缘配置服务器信息包括至少一个边缘配置服务器的标识信息以及至少一个边缘配置服务器中每个边缘配置服务器所对应的至少一个移动网络的标识信息;所述终端装置根据所述终端装置接入的移动网络在所述至少一个边缘配置服务器中确定为所述终端装置服务的第一边缘配置服务器;其中,所述第一边缘配置服务器所对应的至少一个移动网络包括所述终端装置接入的移动网络。相似的,述终端装置接入的移动网络可以为第一信息,可参照在上一种方式中的关于第二信息的说明;边缘配置服务器信息可以为第三信息,可参照在上一种方式中的关于第二信息的说明。
通过本申请实施例提供的技术方案,能够从支持为终端装置服务器的边缘配置服务器中选择与终端装置处于同一PLMN中的边缘配置服务器,确保为终端装置选择数据传输效率更高的边缘配置服务器。
本申请实施例还提供一种边缘使能服务器的确定方法,终端装置向边缘配置服务器发起服务提供流程,具体的,终端装置向边缘配置服务发送服务提供请求信息时,终端装置在服务提供请求信息中至少携带该终端装置当前接入的PLMN的标识信息,然后边缘配置服务器根据终端装置当前接入的PLMN的标识信息为终端装置选择边缘使能服务器。通过本申请实施例提供的技术方案,能够最大程度地选择位于该终端装置当前接入的PLMN中的边缘使能服务器,如此,终端装置处于漫游状态时,终端装置可以从该终端当前接入的PLMN(即VPLMN)中的EES获取应用数据,终端装置无需从HPLMN中的EES获取应用数据,可以节省信令资源,能够保证终端装置与边缘使能服务器之间的路径最优,从而提升终端装置的业务质量。也就是说,通过本申 请实施例提供的技术方案能够确保为终端装置选择更加合适的边缘使能服务器。
本申请实施例提供的边缘配置服务器的确定方法可以应用于终端装置接入的移动网络不同于终端装置的归属的移动网络的场景,如终端装置漫游的场景,也可以应用于终端装置非漫游的场景。在以下实施例中,以终端装置处于漫游状态为例对本申请实施例的方案进行描述,本申请实施例提供过的边缘配置服务器的确定方法也可以应用于多运营商的场景,例如跨运营商的漫游场景(以下实施例称为第一应用场景)、公有云和运营商合作的漫游场景(以下实施例称为第二应用场景)。
图10为本申请实施例的第一应用场景中网络部署的示例,其中,MNO1是终端装置的归属运营商,可以理解为终端装置的归属网络中的本地运营商,MNO 2是终端装置的一个访问运营商,可以理解为访问网络中的本地运营商。
应理解,归属网络中的MNO1的ECS和EES由MNO 1部署和管理,在访问网络中,MNO 1也可以部署该MNO 1的ECS和EES,具体的,MNO 1可以租用访问网络中的边缘基础设施来部署该MNO 1的ECS和EES,并且由MNO 1管理。访问网络中的MNO 2的ECS和EES由MNO 2部署和管理。
对于图10中的(a)所示的网络部署示意图,ECS 1-1是终端装置的归属网络(即HPLMN)中部署的属于MNO1的ECS,相应的,EES 1-1是归属网络中部署的属于MNO1的EES,并且在访问网络(即VPLMN)中部署了MNO 1的ECS和EES,例如图10中的(a)中的ECS 1-2和EES 1-2。其中,ECS 1-2是访问网络中部署的属于MNO 1的ECS,相应的,EES 1-2是访问网络中部署的属于MNO 1的EES。在图10中的(a)中,ECS 2是访问网络中部署的属于MNO 2的ECS,相应地,EES 2是访问网络中部署的属于MNO 2的EES。ECS可以访问和/或管理的EES,也可以称为ECS所对应的EES。上述图10中的(a)中的ECS 1-1可以控制管理EES 1-1;ECS 1-2可以控制管理EES 1-2,ECS 2可以控制管理EES 2。
可选地,在实际部署中,访问网络中也有可能未部署MNO 1的ECS和EES。
需要说明的是,对于上述图10中的(a)所示的第一应用场景的网络部署,归属网络中的属于MON 1的ECS不支持发现访问网络中的属于MON 1的EES,即归属网络中的属于MON 1的ECS不具有控制管理访问网络中的属于MON 1的EES的权限或者能力。例如,图10中的(a)中的ECS 1-1不支持发现EES 1-2,即ECS 1-1不能控制管理EES 1-2。
可选地,在一种情况下,第一应用场景的网络部署可以为图10中的(b),在图10中的(b)中,ECS 1-1是终端装置的归属网络(即HPLMN)中部署的属于MNO1的ECS,相应的,EES 1-1是归属网络中部署的属于MNO1的EES,在访问网络(即VPLMN)中部署了MNO 1的EES,例如图10中的(b)中的EES 1-2,即EES 1-2是访问网络中部署的属于MNO 1的EES。应注意,在访问网络中未部署MON 1的ECS。在图10中的(b)中,ECS 2是访问网络中部署的属于MNO 2的ECS,相应地,EES 2是访问网络中部署的属于MNO 2的EES。
上述图10中的(b)中的ECS 1-1可以控制管理EES 1-1和EES 1-2;ECS 1-2可以控制管理EES 1-2,ECS 2可以控制管理EES 2。
需要说明的是,对于上述图10中的(b)所示的第一应用场景的网络部署,访问 网络中未部署属于MON 1的ECS,在这种情况下,访问网络中的属于MON 1的EES由归属网络中的属于MON 1的ECS控制管理。也就是说,归属网络中的属于MON 1的ECS支持发现访问网络中的属于MON 1的EES,即归属网络中的属于MON 1的ECS具有控制管理访问网络中的属于MON 1的EES的权限或者能力。例如,图10中的(b)中的ECS 1-1支持发现EES 1-2,即ECS 1-1可以控制管理EES 1-2。
下面通过其它实施例,进一步阐述本申请的方案。在下述实施例中,以ECS的地址信息作为一种标识信息来说明,地址信息对应PLMN的标识信息也可理解为ECS对应PLMN的标识信息。
图11为本申请实施例的第二应用场景中网络部署的示例,该场景是第三方的ECS提供者(ECSP)与运营商合作的场景,即不同的运营商共享第三方ECSP中的ECS。图11中的EES 1-1是终端装置的归属网络中部署的属于MNO 1的EES,EES 1-2是终端装置的访问网络中部署的属于MNO 1的EES。
在图11所示的场景中,第三方ECSP中的ECS可以控制管理MNO 1在归属网络中部署的EES和MNO 1在访问网络中部署的EES。
基于上述实施例介绍的边缘应用架构、5G通信系统的架构以及上述两种应用场景,核心网网元可以确定为终端装置提供服务的边缘配置服务器(以下称为第一边缘配置服务器),然后核心网网元将第一边缘配置服务器的地址信息发送至终端装置。或者终端装置可以确定为该终端装置提供服务的边缘配置服务器。
一、核心网网元确定第一边缘配置服务器
如图12所示,本申请实施例提供的边缘配置服务器的确定方法,该方法包括步骤1201至步骤1206。
步骤1201、核心网网元根据第一信息和第二信息,确定第一边缘配置服务器。
其中,第一信息包括终端装置当前接入的PLMN的标识信息,所述核心网网元还可获取第二信息,第二信息可以包括支持为终端装置提供服务的边缘配置服务器的地址信息和与该地址信息对应的PLMN的标识信息。
可选地,边缘配置服务器的地址信息包括但不限于边缘配置服务器的IP地址、统一资源定位符(uniform resource locator,URL)或全限定域名(fully qualified domain name,FQDN)中的一种。
本申请实施例中,支持为终端装置提供服务的边缘配置服务器可以包括终端装置当前接入的PLMN中的边缘配置服务器,当终端装置处于漫游状态时,支持为终端装置提供服务的边缘配置服务器还可以进一步包括终端装置的HPLMN中的边缘配置服务器。且该边缘配置服务器所对应的至少一个边缘使能服务器支持为该终端装置服务。
本申请实施例中,核心网网元可以获取上述第二信息,该第二信息可以来自统一数据管理功能网元的本地配置信息,具体的,可以来自于本地配置信息中的签约信息或者漫游优选信息;或者,第二信息来自于会话管理功能网元确定的映射信息;或者来自策略控制功能网元确定的策略信息,具体的,可以来自于策略信息中的接入网发现和选择策略(ANDSP)或路由选择策略(URSP)。
在一种示例中,以上述第一应用场景(即跨运营商的漫游场景)为例,MNO 1是终端装置的归属运营商,MNO 2、MNO 3是终端装置的漫游运营商。参考图13A, MNO 1在访问网络1(记为VPLMN 1)中部署有ECS和对应的EES,MNO 1在访问网络2(记为VPLMN 2)中部署有ECS和对应的EES。如图13A所示,将MNO 1在终端装置的HPLMN中部署的ECS记为ECS 1-1,对应的EES记为EES 1-1,将MNO 1在VPLMN 1中部署的ECS记为ECS 1-2,对应的EES记为EES 1-2,将MNO 1在VPLMN 2中部署的ECS记为ECS 1-3,对应的EES记为EES 1-3,VPLMN 1中的MNO 2部署的ECS记为ECS 2,对应的EES记为EES 2,VPLMN 2中的MNO 3部署的ECS记为ECS 3,对应的EES记为EES 3。
可以理解的是,HPLMN中的ECS 1-1可以访问和/或管理HPLMN中部署的EES 1-1,VPLMN 1中的ECS 1-2可以访问和/或管理VPLMN 1中的EES 1-2,VPLMN 2中的ECS 1-3可以访问和/或管理VPLMN 2中的EES 1-3。
需要说明的是,由于终端装置的HPLMN中的边缘配置服务器不支持发现终端装置的VPLMN中的边缘使能服务器,因此上述HPLMN中的ECS 1-1不支持发现VPLMN 1中MNO 1部署的EES 1-2,即ECS 1-1不能访问和/或管理VPLMN 1中部署的EES 1-2。同理,ECS 1-1也不能访问和/或管理VPLMN 2中的部署的EES 1-3。
结合图13A示意的场景,在一个示例中,当终端装置当前接入VPLMN 1,上述第二信息中的ECS的地址信息与地址信息对应的PLMN的标识信息的对应关系如下表3所示。
表3
ECS的地址信息 PLMN的标识信息(PLMN ID)
ECS 1-1的地址信息 HPLMN的标识信息
ECS 1-2的地址信息 VPLMN 1的标识信息
ECS 2的地址信息 VPLMN 1的标识信息
结合表3可知,由于ECS 1-1仅能访问和/或管理EES 1-1,不能访问EES 1-2和EES 1-3,因此,在表3所示的第二信息中,ECS 1-1的地址信息仅对应HPLMN的标识信息,表明HPLMN中的ECS仅可以访问和/或管理该HPLMN中的EES。图13A中的ECS1-3和ECS3为另一个VPLMN中的ECS,不支持为终端服务。
在另一个示例中,以上述第一应用场景(即跨运营商的漫游场景)为例,MNO 1是终端装置的归属运营商,MNO 2、MNO 3是终端装置的漫游运营商。参考图13B,MNO 1在访问网络1(记为VPLMN 1)中部署有EES,未部署ECS;MNO 1在访问网络2(记为VPLMN 2)中部署有EES和ECS。如图13B所示,将MNO 1在终端装置的HPLMN中部署的ECS记为ECS 1-1,对应的EES记为EES 1-1,将MNO 1在VPLMN 1中部署的EES记为EES 1-2,将MNO 1在VPLMN 2中部署的ECS记为ECS 1-3,对应的EES记为EES 1-3,VPLMN 1中的MNO 2部署的ECS记为ECS 2,对应的EES记为EES 2,VPLMN 2中的MNO 3部署的ECS记为ECS 3,对应的EES记为EES 3。
可以理解的是,HPLMN中的ECS 1-1可以访问和/或管理HPLMN中部署的EES 1-1,也可以访问和/或管理VPLMN 1中部署的EES 1-2,VPLMN 1中的ECS 2可以访问和/或管理VPLMN 1中的EES 2,VPLMN 2中的ECS 3可以访问管理VPLMN 2中的EES 3,VPLMN 2中的ECS 1-3可以访问管理VPLMN 2中部署的EES 1-3。
结合图13B示意的场景,在一个示例中,当终端装置当前接入VPLMN 1,上述第二信息中的ECS的地址信息与地址信息对应的PLMN的标识信息的对应关系如下表4(a)所示。
表4(a)
Figure PCTCN2021084796-appb-000004
结合图13B示意的场景,在另一个示例中,当终端装置当前接入VPLMN2,上述第二信息中的ECS的地址信息与地址信息对应的PLMN的标识信息的对应关系如下表4(b)所示。其中,ECS 1-1的地址信息对应的VPLMN 1的标识信息为可选。
表4(b)
Figure PCTCN2021084796-appb-000005
在又一个示例中,以上述第一应用场景(即跨运营商的漫游场景)为例,MNO 1是终端装置的归属运营商,MNO 2是终端装置的漫游运营商。参考图13C,MNO 1在VPLMN 1和VPLMN 2中部署均未部署ECS和EES。如图13C所示,将MNO 1在终端装置的HPLMN中部署的ECS记为ECS 1,VPLMN 1中的MNO 2部署的ECS记为ECS 2,VPLMN 2中的MNO 3部署的ECS记为ECS 3。在该场景下,在一个示例中,当终端装置当前接入VPLMN 1,上述第二信息中的ECS的地址信息与地址信息对应的PLMN的标识信息的对应关系如下表5所示。
表5
ECS的地址信息 PLMN的标识信息(PLMNID)
ECS1的地址信息 HPLMN的标识信息
ECS2的地址信息 VPLMN 1的标识信息
可选地,上述第二信息中的PLMN的标识信息包括终端装置当前接入的VPLMN的标识信息。结合图12,上述步骤1201可以通过步骤1201a实现。
步骤1201a、核心网网元将第二信息中,与终端装置当前接入的PLMN标识信息对应的至少一个边缘配置服务器确定为第一边缘配置服务器。
示例性的,对于上述图13A的场景,终端装置当前处于漫游状态,且终端装置位于VPLMN 1,即终端装置当前接入的PLMN为VPLMN 1,结合上述表3,确定的与终端装置当前接入的PLMN的标识信息对应的边缘配置服务器为ECS 1-2以及ECS 2,核心网网元可以从ECS 1-2以及ECS 2中任意确定一个ECS作为第一边缘配置服务器;也可确定多个ECS作为第一边缘配置服务器,由终端任意选择或根据归属运营商或业务类型等信息来选择。
对于上述图13B的场景,终端装置当前处于漫游状态,且终端装置位于VPLMN 1,即终端装置当前接入的PLMN为VPLMN 1,结合上述表4(a),确定的与终端装置当前接入的PLMN的标识信息对应的边缘配置服务器为ECS 1-1以及ECS 2,核心网网元可以从ECS 1-1以及ECS 2中任意确定一个ECS作为第一边缘配置服务器;也可确定多个ECS作为第一边缘配置服务器,由终端任意选择或根据归属运营商或业务类型等信息来选择。
此外,对于图13B的场景,当终端当前接入的PLMN为VPLMN 2,结合上述表4(b),确定的与终端装置当前接入的PLMN的标识信息对应的边缘配置服务器为ECS 1-1、ECS 1-3和ECS 3,核心网网元可以从ECS 1-1、ECS 1-3和ECS 3中任意确定一个ECS作为第一边缘配置服务器;也可确定多个ECS作为第一边缘配置服务器,由终端任意选择或根据归属运营商或业务类型等信息来选择;由此可以避免选择到HPLMN中的ECS和EES,进一步避免了为UE建立低效的数据传输路径,提高了数据传输效率。
对于上述图13C的场景,终端装置当前处于漫游状态,且终端装置位于VPLMN 1,即终端装置当前接入的PLMN为VPLMN 1,结合上述表5,确定的与终端装置当前接入的PLMN的标识信息对应的边缘配置服务器为ECS 2,即第一边缘配置服务器可以包括ECS 2。
结合上述实施例的描述,可知核心网网元为终端装置确定的第一边缘配置服务器的数量可以为一个或多个,第一边缘配置服务器的数量与网络的部署情况有关,本申请实施例对第一边缘配置服务器的数量不作限定。
可选地,上述第一信息中还包括终端装置的归属运营商信息、终端装置的业务指示信息中的至少一种。如此,核心网网元可以根据终端装置的归属运营商信息、业务指示信息中的至少一种、终端装置当前接入的PLMN的标识信息以及第二信息,确定第一边缘配置服务器。
当第一信息中包括终端装置当前接入的PLMN的标识信息和终端装置的归属运营商信息时,上述步骤1201通过步骤1201b实现。
步骤1201b、核心网网元根据终端装置当前接入的PLMN的标识信息、终端装置的归属运营商信息以及第二信息,确定第一边缘配置服务器。
可选地,上述第二信息中还可以包括为终端装置提供服务的边缘配置服务器所对应的运营商信息。
在一种实现方式中,核心网网元将第二信息中,与终端装置当前接入的PLMN标识信息对应的至少一个边缘配置服务器确定为候选边缘配置服务器;然后根据终端装置的归属运营商信息,将候选边缘配置服务器中属于终端装置的归属运营商的边缘配 置服务器确定为第一边缘配置服务器。
以图13A的场景为例,根据第二信息和终端装置当前接入的PLMN标识信息确定的候选边缘配置服务器包括ECS 1-2以及ECS 2,该终端装置的归属运营商为MNO 1,由于上述2个ECS中,ECS1-2属于MNO 1,则核心网网元从上述2个候选边缘配置服务器中确定ECS1-2作为第一边缘配置服务器。
以图13B的场景且终端装置当前接入VPLMN 1为例,根据第二信息和终端装置当前接入的PLMN标识信息确定的候选边缘配置服务器包括ECS1-1和ECS 2,该终端装置的归属运营商为MON 1,由于上述2个ECS中,ECS 1-1属于MON 1,则核心网网元从上述2个候选边缘配置服务器中确定ECS 1-1作为第一边缘配置服务器;以终端装置当前接入VPLMN 2为例,根据第二信息和终端装置当前接入的PLMN标识信息确定的候选边缘配置服务器包括ECS1-3和ECS 3,该终端装置的归属运营商为MON 1,由于上述2个ECS中,ECS 1-3属于MON 1,则核心网网元从上述2个候选边缘配置服务器中确定ECS 1-3作为第一边缘配置服务器。
在另一种实现方式中,核心网网元根据终端装置的归属运营商信息,将第二信息中,属于终端装置的归属运营商的至少一个边缘配置服务器确定为候选边缘配置服务器;然后核心网网元将上述候选边缘配置服务器中与终端装置当前接入的PLMN标识信息对应的边缘配置服务器确定为第一边缘配置服务器。
应理解,通过步骤1201b的上述两种实现方式确定的第一边缘配置服务器相同。
同理,可选地,上述核心网网元也可以同时根据终端装置当前接入的PLMN标识信息,确定出第二信息中与终端装置当前接入的PLMN标识信息对应的至少一个边缘配置服务器;并根据终端装置的归属运营商信息,确定第二信息中属于终端装置的归属运营商的至少一个边缘配置服务器,进而将既属于终端装置的归属运营商,又与终端装置当前接入的PLMN标识信息对应的边缘配置服务器确定为第一边缘配置服务器。
以图13B的场景且终端装置当前接入VPLMN 1为例,根据第二信息和终端装置当前接入的PLMN标识信息确定的候选边缘配置服务器包括ECS1-1以及ECS 2,该终端装置位于VPLMN 1,由于上述2个ECS中,ECS 2位于VPLMN 1,则核心网网元从上述2个候选边缘配置服务器中确定ECS 2作为第一边缘配置服务器。
当第一信息中包括终端装置当前接入的PLMN的标识信息和终端装置的业务指示信息时,上述步骤1201通过步骤1201c实现。
步骤1201c、核心网网元根据终端装置当前接入的PLMN的标识信息、终端装置的业务指示信息以及第二信息,确定第一边缘配置服务器。
可选地,终端装置的业务指示信息可以包括业务类型指示信息和/或业务质量指示信息等,业务类型指示信息用于指示终端装置当前的业务类型,例如视频业务、车联网业务、游戏业务等;业务质量指示信息用于指示终端装置的业务质量的需求,例如业务质量指示信息指示终端装置的业务的QoS信息。
可选地,上述第二信息中还可以包括为终端装置提供服务的边缘配置服务器的业务能力信息,即边缘配置服务器所支持的业务类型。
在一种实现方式中,核心网网元将第二信息中,与终端装置当前接入的PLMN标识信息对应的至少一个边缘配置服务器确定为候选边缘配置服务器;然后核心网网元 根据终端装置的业务指示信息,将上述候选边缘配置服务器中满足终端装置的业务需求的边缘配置服务器确定为第一边缘配置服务器。此外,ECS是否支持该业务类型,可根据ECS所对应的EES是否支持服务该业务类型来确定。
例如,以图13A的场景为例,根据第二信息和终端装置当前接入的PLMN标识信息确定的候选边缘配置服务器包括ECS 1-2以及ECS 2,假设终端装置当前的业务为游戏业务(即终端装置的业务指示信息),ECS 1-2支持的业务服务为车联网业务,ECS 2可提供的业务服务为游戏业务,则核心网网元从上述2个候选边缘配置服务器中确定可提供车联网业务的ECS 2作为第一边缘配置服务器。
例如,以图13B的场景且终端装置当前接入VPLMN 1为例,根据第二信息和终端装置当前接入的PLMN标识信息确定的候选边缘配置服务器包括ECS 1-1以及ECS 2,假设终端装置当前的业务为视频业务(即终端装置的业务指示信息),上述ECS 1-1可提供的业务服务为视频业务,ECS 2可提供的业务服务为游戏业务,则核心网网元从上述2个候选边缘配置服务器中确定可提供视频业务的ECS 1-1作为第一边缘配置服务器。
在另一种实现方式中,核心网网元也可以先根据终端装置的业务指示信息,将第二信息中,满足终端装置的业务需求的至少一个边缘配置服务器确定为候选边缘配置服务器;然后核心网网元将上述候选边缘配置服务器中与终端装置当前接入的PLMN标识信息对应的边缘配置服务器确定为第一边缘配置服务器。
应理解,通过步骤1201c的上述两种实现方式确定的第一边缘配置服务器相同。
可选地,上述核心网网元也可以同时根据终端装置当前接入的PLMN标识信息,确定出第二信息中与终端装置当前接入的PLMN标识信息对应的至少一个边缘配置服务器;并根据终端装置的业务指示信息,确定第二信息中满足终端装置的业务需求的至少一个边缘配置服务器,进而将既满足终端装置的业务需求,又与终端装置当前接入的PLMN标识信息对应的边缘配置服务器确定为第一边缘配置服务器。
可选地,核心网网元可以根据终端装置的归属运营商信息、业务指示信息、终端装置当前接入的PLMN的标识信息以及第二信息,确定第一边缘配置服务器,在这种情况下,第一边缘配置服务器需同时满足下述三个条件:第一边缘配置服务器属于终端装置的归属运营商、第一边缘配置服务器满足终端装置的业务需求以及第一边缘配置服务器位于该终端装置当前接入的PLMN。
步骤1202、核心网网元将第一边缘配置服务器的地址信息发送至终端装置。
步骤1203、终端装置从核心网网元接收第一边缘配置服务器的地址信息。
步骤1204、终端装置向第一边缘配置服务器发送服务提供请求信息,该服务提供请求信息中包括终端装置当前接入的PLMN的标识信息。
参考上述实施例中对于现有的服务提供流程的描述,上述服务提供请求信息中还包括终端装置的位置信息或终端装置的标识信息、服务需求、服务偏好和连接性等信息。
可选地,上述服务提供请求信息中还包括终端装置的数据网络标识,该数据网络的标识可以为DNAI或服务集标识(service set identifier,SSID),其中,DNAI为3GPP对应的数据网络标识,SSID为非3GPP对应的数据网络标识。

步骤1205、第一边缘配置服务器根据终端装置当前接入的PLMN的标识信息,确定为终端装置提供服务的边缘使能服务器。
示例性的,结合上述图13A的部署场景,终端装置当前接入的PLMN为VPLMN 1,如果上述核心网网元根据步骤1201a-1201c任一方法确定的第一边缘配置服务器为ECS 1-2,终端装置向ECS 1-2发送服务提供请求信息,由于ECS 1-2可以访问管理EES 1-2,则第一边缘配置服务器根据终端装置当前接入的PLMN(即VPLMN 1)的标识信息确定为终端装置提供服务的边缘使能服务器为位于VPLMN 1中的EES 1-2。
示例性的,结合上述图13B的部署场景,终端装置当前接入的PLMN为VPLMN 1,上述核心网网元根据步骤1201a-1201c任一方法确定的第一边缘配置服务器为ECS 1-1,终端装置向ECS 1-1发送服务提供请求信息,由于ECS 1-1可以访问管理EES 1-1和EES 1-2,其中,EES 1-1部署在HPLMN中,EES 1-2部署在VPLMN 1中,则第一边缘配置服务器根据终端装置当前接入的PLMN(即VPLMN 1)的标识信息确定为终端装置提供服务的边缘使能服务器为位于VPLMN 1中的EES 1-2。
