本实施例中的第一边缘配置服务器配置信息具体可参照前述实施例中的第一边缘配置服务器配置信息和表1所述，这里不再赘述。
下面结合具体的示例对本申请实施例的边缘配置服务器信息处理方法进行说明。
示例一
本示例通过能力开放将ECS配置信息更新到SMF的方案，具体是SMF获取来自AF的第二边缘配置服务器配置信息的实现方式。图4为本申请实施例的边缘配置服务器信息处理方法的交互流程示意图一；如图4所示，所述方法包括：
步骤300：SMF向UDM发送订阅请求消息(Nudm_SDM_subscribe request)，所述订阅请求消息用于请求ECS配置信息(即第二边缘配置服务器配置信息)。
步骤301：AF向NEF发送信息创建/更新请求，请求消息中包括ECS配置信息(即第二边缘配置服务器配置信息)。
示例性的，AF可向NEF发送Nnef_ParameterProvision_Create/Nnef_ParameterProvision_Update消息，消息中携带上述ECS配置信息(即第二边缘配置服务器配置信息)。
其中，上述消息中可包括：GPSI、预期UE行为参数(Expected UE Behaviour parameters)、网络配置参数(Network Configuration parameters)、ECS配置信息(ECS Info Data)、外部组标识和5G虚拟网络(VN)组数据(External Group Id and 5G VN group data)、5GVN组成员管理参数(5G VN group membership management parameters)等等。
步骤302：如果AF被NEF授权可以进行参数提供的操作，则NEF向UDM发送信息创建/更新/删除请求，请求消息中包括ECS配置信息(即第二边缘配置服务器配置信息)。
示例性的，NEF可向UDM发送Nudm_ParameterProvision_Update/Nudm_ParameterProvision_Create/Nudm_ParameterProvision_Delete消息，消息中携带上述ECS配置信息(即第二边缘配置服务器配置信息)。
其中，上述更新请求消息、创建请求消息和删除请求消息中可包括GPSI、AF ID、业务参考标识(Transaction Reference ID(s))、ECS信息(ECS Info Data)、NEF参考标识(NEF reference ID)等等，来创建、更新或删除UDM中提供的订阅用户数据预配置参数(包括ECS信息)。
步骤303：UDM使用向NEF发送响应消息。
示例性的，UDM向NEF发送Nudm_ParameterProvision_Create Response/Nudm_ParameterProvision_Update Response/Nudm_ParameterProvision_Delete Response消息。如果步骤302过程失败，则响应消息中还可包括指示失败原因的原因值。
步骤304：NEF向AF发送响应消息。
示例性的，NEF向AF发送Nnef_ParameterProvision_Create Response/Nnef_ParameterProvision_Update Response消息。如果该过程失败，则响应消息中还可包括指示失败原因的原因值。
步骤305：UDM向SMF发送通知消息，所述通知消息中包括UE的签约信息，UE的签约信息中包括上述ECS配置信息(即第二边缘配置服务器配置信息)。
示例性的，UDM向SMF发送Nudm_SubscriberDataManagement(SDM)_Notification消息，将已更新的订阅用户数据(UE的签约数据)通知SMF。其中，消息中还可包括SUPI、与SMF相关的参数集、DNN、单网络片选择辅助信息(S-NSSAI，Single Network Slice Selection Assistance Information)等。SMF存储接收到相关参数，并可根据来自UDM的消息中包含的DNN和S-NSSAI将参数与PDU会话相关联。
可选地，SMF可向UDM返回确认响应(ACK)。
示例二
基于上述示例一，本示例示意SMF将ECS信息更新到UE。图5为本申请实施例的边缘配置服务器信息处理方法的交互流程示意图二；如图5所示，所述方法包括：
步骤401：同上述示例一中流程，AF通过能力开放，将更新的ECS配置信息配置到UDM，并同步到SMF。
步骤402：SMF做出策略决定。SMF可以确定是否需要将更新的ECS配置信息发送到AMF。本示例中，SMF向AMF发送更新的ECS配置信息。
示例性的，SMF通过PDU会话修改(PDU session modification)流程中的Namf_Communication_N1N2MessageTransfer消息将更新的ECS配置信息发送到AMF。
步骤403：AMF向(无线)接入网((R)AN，(Radio)Access Network)设备发送更新的ECS配置信息。
示例性的，AMF可通过N2 PDU会话请求(N2 PDU Session Request)消息向(R)AN设备发送更新的ECS配置信息。
步骤404：(R)AN设备向UE发送更新的ECS配置信息(透传)。
示例性的，(R)AN设备通过非接入层(NAS，Non-Access-Stratum)消息，例如AN specific signalling exchange消息，向UE发送更新的ECS配置信息。其中，消息中还可包括PDU会话标识(PDU Session ID)、N1 SM container(可包括PDU Session Establishment Accept)等等。
上述步骤402至步骤404为通过PDU会话修改流程将更新的ECS配置信息发送至UE的过程，这种方式有可能产生信令风暴。基于此，为了避免产生信令风暴，还可通过超文本传输协议(HTTP，Hyper Text Transfer Protocol)重定向的方式将UE的请求转发至新的ECS。
可选地，通过重定向的方式将UE的请求转发至新的ECS，包括：第 一边缘配置服务器接收来自用户设备的第一请求消息，向所述用户设备发送第二边缘配置服务器配置信息，所述第二边缘配置服务器配置信息用于所述用户设备将所述第一请求消息重定向至第二边缘配置服务器。
示例三
本示例为UE示意通过NAS信令获得ECS信息的完整方案。图6为本申请实施例的边缘配置服务器信息处理方法的交互流程示意图三；如图6所示，所述方法包括：
步骤501：UE通过(R)AN设备向AMF发送PDU会话建立请求(PDU Session Establishment Request)消息，所述消息中包括用于请求边缘配置服务器配置信息的指示信息。
示例性的，UE通过NAS消息发起PDU建立请求，请求消息中可包括：S-NSSAI(s)、DNN、PDU Session ID、请求类型(Request type)、旧PDU会话标识(Old PDU Session ID)、PCO、N1 SM container(PDU Session Establishment Request)等等；其中，DNN可能用于SMF选择相应的ECS。
本示例中，在PCO的附加参数列表(additional parameters list)中增加一个容器标识符(container identifier)(0040H(0040H可表示闲置字段，ECS Info Request))以表示用于请求边缘配置服务器配置信息的指示信息。
步骤502：AMF选择SMF。
步骤503：AMF向SMF发送会话建立请求消息，所述请求消息中包括用于请求边缘配置服务器配置信息的指示信息。所述指示信息的实现方式与步骤501中通过PCO承载指示信息的实现方式相同，这里不再赘述。
示例性的，会话建立请求消息可以是Nsmf_PDUSession_CreateSMContext Request消息，消息中还可包括：SUPI、DNN、S-NSSAI(s)、PDU Session ID、N1 SM container(包括PDU会话建立请求(PDU Session Establishment Request))、用户位置信息(User location  information)(也可称为用户设备位置信息)、接入类型(Access Type)、PEI、GPSI等等。
步骤504：SMF从UDM检索用户数据，确定用户是否购买边缘计算业务，并获取ECS配置信息。
示例性的，SMF可使用Nudm_SDM_Get消息检索用户数据，确定用户是否购买边缘计算业务，并获取ECS配置信息。其中，消息中可包括：SUPI、会话管理订阅数据(Session Management Subscription data)、DNN、S-NSSAI(S-NSSAI可以是归属地的S-NSSAI)。
本步骤中，如果归属地的相应SUPI、DNN和S-NSSAI的会话管理订阅数据不可用，则SMF使用Nudm_SDM_Get消息(携带归属地的SUPI、会话管理订阅数据、DNN、S-NSSAI)到UDM检索，利用会话管理订阅数据并进行订阅。UDM可以通过Nudr_DM_Query消息从UDR获取此相关信息(例如包括SUPI、用户订阅数据、会话管理订阅数据、归属地的DNN和S-NSSAI等)，并且可以通过Nudr_DM_subscribe消息订阅来自UDR的相同数据的通知。
本步骤为可选步骤。
步骤505：SMF执行常规的PDU会话建立流程。需要说明的是，执行常规的PDU会话建立流程中所涉及到的网络设备不限于图6中所示。
步骤506：SMF根据用户设备的位置信息、边缘配置服务器服务范围、边缘配置服务器选择优先级中的至少一种信息，决定第一边缘配置服务器配置信息(第一ECS配置信息)，并向AMF发送第一ECS配置信息。
本步骤中，SMF可以通过前述示例一或示例二记载的实施例获得第二ECS配置信息，第二ECS配置信息包括以下至少一种信息：边缘配置服务器的地址、边缘配置服务器的服务范围、边缘配置服务器的选择优先级、边缘配置服务器的属性信息。SMF可基于用户设备的位置信息、第二ECS 配置信息中的边缘配置服务器服务范围、边缘配置服务器选择优先级(第二ECS配置信息中的边缘配置服务器选择优先级或者本地配置的边缘配置服务器选择优先级)中的至少一种信息确定第一ECS配置信息，第一ECS配置信息包括以下至少一种信息：边缘配置服务器的地址、边缘配置服务器的服务范围、边缘配置服务器的选择优先级、边缘配置服务器的属性信息。
示例性的，所述第一ECS配置信息中若包括边缘配置服务器的选择优先级，则所述边缘配置服务器的选择优先级也可称为ECS规则、ECS规则信息、ECS优先级排序等等。例如，边缘配置服务器的选择优先级可以是边缘配置服务器对应的优先级，或者边缘配置服务器按照优先级大小的排序。
示例性的，SMF通过Namf_Communication_N1N2MessageTransfer消息向AMF发送第一ECS配置信息。其中，消息中可包括：PDU Session ID、N2会话管理信息(N2 SM information(可包括PDU Session ID,QFI(s)等等))、N1 SM container(可包括PDU Session Establishment Accept(可包括QoS规则以及QoS流等级QoS参数(QoS Rule(s)and QoS Flow level QoS parameters)、选择的会话和服务连续模式(selected SSC mode，selected Session and Service Continuity mode)、S-NSSAI(s)、DNN、分配的IPv4地址(allocated IPv4 address)、接口标识符(interface identifier)、会话聚合最大比特速率(Session-AMBR，Session-Aggregated Maximum Bit Rate)、选择的PDU会话类型(selected PDU Session Type)、ECS Info信息等等)。可选地，可通过消息的PCO的additional parameters list里面增加一个container identifier(0041H(ECS Info Response))以表示第一ECS配置信息。
步骤507：AMF向(R)AN设备发送第一ECS配置信息。
示例性的，AMF可通过N2 PDU会话请求(N2 PDU Session Request) 消息向(R)AN设备发送第一ECS配置信息。其中，请求消息中还可包括：N2会话管理信息(N2 SM information)、NAS消息(NAS message)等等；其中，NAS消息(NAS message)中可包括PDU Session ID、N1 SM container(可包括PDU Session Establishment Accept)等等。
