现阶段，提出用户路由选择策略(user routing selection policy，URSP)需支持边缘计算业务。边缘计算业务可简单理解为，应用功能(application function，AF)可选择在边缘位置动态部署应用服务，如体育场馆在重大赛事期间可通过部署直播/回放业务，实现该场馆区域内观众切换观看视角、回放精彩环节等功能，提升用户观看体验。通常而言，由于该业务需保证大带宽、低时延，该业务可能仅允许临近区域内的用户接入访问。
在接入特定业务时，终端设备需根据URSP规则选择正确的协议数据单元(protocol data unit，PDU)会话配置参数，以便接入特定应用服务并获得相应的服务质量保障。然而，对于动态部署的应用服务而言，由于任何用户都有可能进入该区域，若为所有用户提前配置该URSP规则，而实际需要接入该业务的用户有限，则会造成信令资源的浪费。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于第五代(5th generation，5G)系统或新无线(new radio，NR)通信系统，也可以应用于未来可能出现的其他的通信系统，如6G通信系统。。
图1是5G系统架构的一个示意图。如图1所示，该系统架构可以包括用户设备(user equipment，UE)101、无线接入网(radio access network，RAN)网元102、策略控制功能(policy control function)103、数据网络(data network，DN)104、接入与移动性管理功能(access and mobility management function，AMF)105、会话管理功能(session management function，SMF)106、策略控制功能(policy control function，PCF)107、应用功能(application function，AF)108、统一数据管理(unified data management，UDM)109、统一数据仓库(unified data repository，UDR)110和网络开放功能(network exposure function，NEF)111。下面对该网络架构中涉及的各个网元分别进行说明。
1、UE：也可以称为终端设备。终端设备可以经RAN网元与一个或多个核心网(core network，CN)进行通信。终端设备可称为接入终端、终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线网络设备、用户代理或用户装置。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 localloop，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设备、车载设备、可穿戴设备或物联网、车辆网中的终端设备以及未来网络中的任意形态的终端设备等。
2、RAN网元：是一种将UE接入到无线网络的设备。RAN网元可以是基站NodeB、演进型基站(evloved NodeB,eNB)、5G移动通信系统中的下一代基站(next generation NodeB，gNB)、传输点、未来移动通信系统中的基站或无线保真(wireless fidelity，Wi-Fi)系统中的接入节点或5G系统中的基站的一个或一组(包括多个天线面板)天线面板。或者，无线接入网设备还可以是构成gNB或传输点的网络节点，如基带单元(baseband unit，BBU)，或，分布式单元(distributed unit，DU)，或，集中式单元(centralized unit，CU)，或，集中式单元控制面(centralized unit control plane，CU-CP)和集中式单元用户面(centralized unit user plane，CU-UP)等。本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。在一些部署中，gNB可以包括CU和DU。一个CU可以连接一个DU，或者也可以多个DU共用一个CU，可以节省成本，以及易于网络扩展。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，以实现无线资源控制(radio resource control，RRC)层，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，以实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。CU和DU的切分可以按照上述协议栈进行切分，本申请实施例中并不完全限定上述协议栈切分方式，还可以有其它的切分方式，具体可以参考TR38.801v14.0.0。
CU和DU之间通过F1接口连接。CU代表gNB通过Ng接口和核心网连接。更进一步，集中式单元CU还可以划分为控制面(CU-CP)和用户面(CU-UP)。其中CU-CP负责控制面功能，主要包含RRC和分组数据汇聚层协议控制面(packet data convergence protocol control，PDCP-C)。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等至少一种功能。CU-UP负责用户面功能，主要包含业务数据适配协议(service data adaptation protocol，SDAP)和分组数据汇聚层协议用户面(packet data convergence protocol  user，PDCP-U)。其中SDAP主要负责将核心网的数据进行处理并将flow映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等至少一种功能。其中CU-CP和CU-UP通过E1接口连接。CU-CP代表gNB通过Ng接口和核心网连接。通过F1-C(控制面)和DU连接。CU-UP通过F1-U(用户面)和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。
gNB还可以包括有源天线单元(active antenna unit，AAU)。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、CU-CP节点、CU-UP节点、AAU节点中一项或多项的设备。此外，CU可以作为接入网中的网络设备，也可以作为核心网(core network，CN)中的网络设备，本申请对此不做限定。
3、UPF：是一种用户面网元，用于分组路由和转发、用户面数据的服务质量(quality of service，QoS)处理以及报文探测和策略规则执行等。
4、DN：用于提供传输数据的网络，例如，Internet网络等。其中，DN可以是数据网络鉴权、授权和计费(data network authentication、authorization、accounting)，也可以是应用服务器(application function，AF)等。
5、AF：一种应用网元，主要传递应用侧对网络侧的需求，例如，服务质量(quality of service，QoS)需求等。AF可以是第三方功能实体，也可以是运营商部署的应用服务，如IP多媒体子系统(IP Multimedia Subsystem，IMS)语音呼叫业务。
6、AMF：一种接入管理网元，主要用于会话管理、UE的网络互连协议(internet protocol，IP)地址分配和管理、选择可管理UPF网元、通过AMF实现与接入网相关的会话信息交互、策略控制和收费功能接口的终结点以及下行数据通知等。
7、NEF：一种网络开放网元，用于安全地向外部开放由3GPP网络功能提供的业务和能力等。
8、NRF：一种网络存储网元，用于保存网络功能实体以及其提供服务的描述信息，以及用于支持服务发现和网元实体发现等。
9、PCF：一种策略控制网元，用于指导网络行为的统一策略框架，为控制平面功能网元(例如AMF，SMF网元等)提供策略规则信息等。
10、UDM：一种数据管理网元，用于实现处理用户标识、接入鉴权、注册以及移动性管理等功能。
11、UDR：一种数据存储网元，主要负责签约数据、策略数据、应用数据等类型数据的存取功能。
可以理解的是，上述各网元既可以是硬件设备，也可以是芯片，或者是在专用硬件上运行软件功能，或者是平台(例如,云平台)上实例化的虚拟化功能。还应理解，图1中所示的一些网元可部署在同一位置(如同一硬件设备或软件功能上)，也可以分开部署，本申请对此不作限定。
应理解，图1中所示的各网元之间的接口仅是一种示例，在实践中，网元之间的接口可能有所改变，比如，网元之间可以采用服务化接口进行通信。
还应理解，上述所涉及的接入管理网元、网络开放网元、策略控制网元、应用网元、数据存储网元等网元，在不同的系统中可能有不同的命名，比如接入管理网元在5G系统中命名为AMF，但在6G系统中可能不是AMF。本领域技术人员可以理解，网元命名的不同并不应对本申请构成任何限定。
为便于理解，下文中，以接入管理网元为AMF、网络开放网元为NEF、策略控制网元为PCF、应用网元为AF、数据存储网元为UDR为例，对本申请提供的方案进行说明。
现阶段，提出URSP需支持边缘计算业务。边缘计算业务可简单理解为，AF可选择在边缘位置动态部署应用服务，如体育场馆在重大赛事期间可通过部署直播/回放业务，实现该场馆区域内观众切换观看视角、回放精彩环节等功能，提升用户观看体验。通常而言，由于该业务需保证大带宽、低时延，该业务可能仅允许临近区域内的用户接入访问。
在接入特定业务时，终端设备需根据URSP规则选择正确的PDU会话配置参数，如DNN、S-NSSAI等信息，以便接入特定应用服务并获得相应的服务质量保障。然而，对于动态部署的应用服务而言，由于任何用户都有可能进入该区域，若为所有用户提前配置该URSP规则，而实际需要接入该业务的用户有限，则会造成信令资源的浪费。
为解决应用服务动态部署场景下URSP无法有效配置的问题，本申请提出了一种配置业务的方法。下面，对本申请提供的方案进行说明。应理解，本申请提供的方法的执行顺序仅由该方法内部逻辑决定，并不由各实施例对应的附图中的附图标记限定。
图2是本申请提供的一种配置业务的方法的示意性流程图。如图2所示，该方法200可以包括S210至S260。下面对各步骤分别说明。
S210，AMF根据第一区域信息，确定目标UE是否位于目标区域。
其中，第一区域信息用于指示目标区域。第一区域信息可以由AF通过NEF，配置给AMF。
目标UE可以是网络内任一UE，也可以是特定的一些UE，这些特定的UE可以由AF通过NEF配置给AMF。
S220，若目标UE位于目标区域，AMF向PCF发送用户策略关联请求消息。
其中，该用户策略关联请求消息用于请求PCF向目标UE配置第一URSP，第一URSP用于目标UE接入第一业务。示例性的，本申请中，用户策略关联请求消息可以是用户策略关联建立请求消息或用户策略关联更新请求消息。
应理解，目标UE位于目标区域可以指目标UE进入目标区域或者目标UE已经位于目标区域。
S230，PCF生成第一URSP。
PCF可以根据应用标识生成第一URSP，其中，应用标识所指示的应用提供第一业务，或者说该应用标识用于指示提供第一业务的应用。
示例性的，本申请中，所述应用标识可以是应用服务提供商(application service Provider，ASP)标识(identifier，ID)，所述ASP ID指示的应用服务提供商ASP提供所述第一业务。或者，所述应用标识可以是应用业务标识(AF Service Identifier)，或者还可以是具体的应用标识信息。
下文中，为便于理解，均以ASP ID代替应用标识来描述。
示例性的，第一URSP可以包括流描述(traffic descriptor，TD)信息和路由选择描述 (route selection descriptor)信息。
其中，流描述信息用于描述第一业务的业务流，可以是第一业务对应的APP ID或IP三元组(目的地址、目的端口号、协议类型)，也可以是域名描述信息等，具体形式可参考现有技术URSP里的流描述的形式。应理解，前述应用标识可以理解为运营商和ASP之间有一致概念的应用标识；而这里APP ID则可以理解为UE与运营商之间有一致概念的应用标识，例如，APP ID可以是该ASP所提供的某一个子应用。
路由选择描述信息可以包括下述中的一项或多项：
(1)时间窗(time window，TW)信息。该时间窗信息可看作路由选择描述信息的时间验证条件，用于指示该路由选择描述信息的有效时间，即只有在该时间窗内，该路由选择描述信息才被认为有效。
(2)第一区域信息。该区域信息可看作路由选择描述信息的位置验证条件，用于指示该路由选择描述信息的有效位置，即只有在该区域内，该路由选择描述信息才被认为有效。
(3)DNN和S-NSSAI。其中，DNN和S-NSSAI可以由NEF根据ASP ID和本地运营商配置信息得到，或者由PCF根据ASP ID和/或流描述信息及本地运营商配置信息或UDR中配置信息得到。
在一种实现方式中，用户策略关联请求消息可以包括ASP ID。可选地，用户策略关联请求消息还可以包括下述中的一项或多项：流描述信息、时间窗信息、第一区域信息、DNN和S-NSSAI。也就是说，可以由AMF提供ASP ID和流描述信息、时间窗信息、第一区域信息、DNN和S-NSSAI中的任一种。另外，若用户策略关联请求消息不包括DNN和S-NSSAI，PCF还可以根据ASP ID和/或流描述信息及本地运营商配置信息或UDR中配置信息确定DNN和S-NSSAI。
在另一种实现方式中，PCF可以从本地或UDR获取ASP ID。PCF还可以从本地或UDR获取流描述信息和/或时间窗信息，以及可以从本地、UDR获取或AMF处获取第一区域信息。其中PCF本地的上述信息和UDR中的上述信息是由AF通过NEF配置的。另外，NEF可以根据本地运营商配置信息对ASP ID映射得到DNN和S-NSSAI，从而PCF还可以从NEF获取该DNN和S-NSSAI。若NEF未执行ASP ID至DNN和S-NSSAI的映射动作，则PCF可以根据ASP ID和/或流描述信息及本地运营商配置信息或UDR中配置信息得到DNN和N-SSAI。
可选地，在一种实现方式中，在S220中，若在所述时间窗信息所指示的时间窗内，目标UE位于目标区域，则AMF向PCF发送用户策略关联请求消息。也就是说，如果目标UE在时间窗信息所指示的时间窗外位于目标区域，则AMF可以不向PCF发送用户策略关联请求消息。那么相应地，在S230中，PCF不需要判断AMF发送用户策略关联请求消息的时间是否在所述时间窗内。
可选地，在另一种具体实现中，在S220中，无论是否在时间窗信息所指示的时间窗内，只要目标UE位于目标区域中，AMF都可以向PCF发送用户策略关联请求消息。PCF可以根据接收到用户策略关联请求消息的时间，确定是否执行S230。如果PCF在时间窗信息所指示的时间窗内接收到用户策略关联请求消息，则执行S230，否则，不执行S230。另外，PCF也可以不判断AMF发送用户策略关联请求消息的时间是否在所述时间窗内， 而由UE根据URSP策略中的时间窗信息判断当前是否执行第一URSP策略。
S240，PCF向AMF发送第一URSP。
S250，AMF向目标UE发送第一URSP。
示例性的，PCF可以通过UE配置更新(UE Configuration Update)流程经由AMF将第一URSP发送给UE。
S260，目标UE根据第一URSP，接入第一业务。
具体地，目标UE收到第一URSP后，在发起该第一URSP所对应的第一业务时，将执行URSP匹配过程，并根据该第一业务所对应的流描述信息匹配至该第一URSP，随后根据所匹配的第一URSP中的路由选择描述信息发起PDU会话建立流程或PDU会话修改流程。
根据本申请提供的方法，目标UE在目标区域时，PCF才给UE配置第一URSP，从而使得目标UE只有在目标区域时，才能根据第一URSP接入相应的业务。相比于现有技术不关心目标UE的位置，提前为所有目标UE配置第一URSP的方案，本申请的方案能够有效配置URSP，避免不必要的信令开销。
应理解，对于在前文中已经进行解释说明的内容，下文中若无特殊说明，均可以参照上文的描述。
下面结合图3至图5所示的详细的流程图，对图2所示的方法进行更为具体地说明。
图3所示的方法中，AMF判断目标UE位于目标区域时，向PCF提供用于生成第一URSP的信息。与图3所示的方法的不同之处在于，图4所示的方法中，NEF将用于生成第一URSP的信息通知给PCF；图5所示的方法中，NEF将用于生成第一URSP的信息通知给UDR，再由UDR提供给PCF。图3所示的方法可以对应S230中描述的第一种方式，图4和图5所示的方法可以对应S230中描述的第二种方式。
图3是一种配置业务的方法的示意性流程图。如图3所示，该方法300可以包括S301至S314中的部分或全部步骤。下面对各步骤分别说明。
S301，AF向NEF发送第二配置请求消息。
例如，AF可以在部署新应用的情况下发送第二配置请求消息，如部署了虚拟现实(virtual reality，VR)体验场馆新增部署VR体验服务，通过发送第二配置请求消息允许馆内用户通过手机接入使用。为保障用户体验，该业务需通过特定DNN/S-NSSAI接入，即AF需在用户接入该体验服务前告知运营商将相应URSP配置至目标用户。再如，AF可以在ASP在特定本地接入数据网络(local access data network，LADN)新增应用接入点的情况下发送第二配置请求消息。ASP在特定LADN新增应用接入点，允许UE通过本地分支接入该应用服务以降低用户面路径环回，此时ASP即可通过运营商网络的URSP提供该LADN信息至UE，以便UE通过正确的LADN网络接入该应用服务。
第二业务配置请求消息用于配置目标UE在目标区域时接入第一业务。具体地，第二业务配置请求消息可以包括上述ASP ID和用于指示目标区域的信息(本申请中记为：第二区域信息)。第二区域信息可以是外部地理区域信息(Geo Info)，但本申请对此不作限定。
可选地，第二配置请求消息还可以携带外部群组标识，该外部群组标识用于指示允许接入第一业务的所有目标UE。示例性的，若第二配置请求消息不包括外部群组标识，则 目标UE可以是网络内任一UE。
可选地，第二配置请求消息还可以包括下述中的一项或多项：
(1)上述流描述信息。
(2)上述时间窗信息。
(3)外部事务(external transaction)标识。外部事务标识用于唯一标识第一业务的配置请求，以便后续通过向NEF发送该外部事务标识，请求更新或取消第一业务的配置请求。第一业务的配置请求，即，与第一业务相关的配置信息或与第一业务相关的配置请求消息。
S302，NEF根据第二配置请求消息，执行第一业务配置授权。
具体地，NEF根据ASP ID判断该ASP ID所指示的ASP是否允许发送对第一业务的配置请求(即，第一配置请求消息)，若允许，则将第二区域信息映射为下述中的一项或多项：运营商网络中的内部位置信息、小区标识列表(List of Cell id(s))、RAN设备列表(List of gNodeB(s))和跟踪区标识(tracking area identifier，TAI)列表(List of TAI(s))。由对第二区域信息映射得到的上述信息可以统称为：第一区域信息。容易理解，第一区域信息所指示的区域和第二区域信息所指示的区域相同，即都为目标区域。
若第二配置请求消息还包括所述外部群组标识，则NEF还可以将外部群组标识映射为内部群组标识(internal group identifier，IGI)。应理解，外部群组标识与内部群组标识所指示的UE相同。
若第二配置请求消息还包括所述外部事务标识，则NEF还可以将外部事务标识映射为内部事务标识(internal transaction identifier，ITI)。
可选地，NEF还可以根据运营商配置信息，将ASP ID映射为DNN和S-NSSAI。
S303，NEF获取为目标区域提供服务的AMF标识信息(或AMF集合信息)。
在一种方式中，NEF可以根据第二区域信息映射出AMF标识信息。
另一种实现方式中，NEF可以向UDM发送第一区域信息，UDM可以根据第一区域信息与AMF标识间的映射关系，判断为该区域提供服务的AMF标识信息，然后UDM可以将该AMF标识信息发送给NEF。
S304，NEF向AMF标识信息所标识的AMF发送第一配置请求消息。
第一配置请求消息包括ASP ID和第一区域信息。
