图1是本申请实施例提供的一种应用实例的地址获取方法的***架构图，该***中包括用户设备(user equipment，UE)、移动数据网络、边缘网络、应用实例、第二服务器和第三服务器。该应用实例和该第三服务器部署在该边缘网络中。FIG. 1 is a system architecture diagram of an address acquisition method of an application example provided by an embodiment of the present application. The system includes a user equipment (UE), a mobile data network, an edge network, an application example, a second server, and a second server. Three servers. The application instance and the third server are deployed in the edge network.

移动数据网络可以是第三代伙伴计划(the 3rd generation partnership project，3GPP)网络。The mobile data network may be the 3rd generation partnership project (3GPP) network.

边缘网络是中心云的对等概念，可以理解为是一个本地的数据中心，可以使用数据网络接入标识(data network access identifier，DNAI)来标识，还可以称为边缘计算网络(edge computing network)。边缘网络中可以部署多个本地数据网络(local data network，local DN)。在一种实现方式中，边缘网络可以是边缘数据网络(edge data network，EDN)。The edge network is the peer-to-peer concept of the central cloud. It can be understood as a local data center. It can be identified by the data network access identifier (DNAI), and it can also be called the edge computing network (edge computing network) . Multiple local data networks (local data network, local DN) can be deployed in the edge network. In one implementation, the edge network may be an edge data network (EDN).

第二服务器可以提供应用的名称到应用的IP地址的解析服务，可以向UE提供边缘网络的配置信息(如边缘网络的名称、IP地址、IP虚拟地址(用于表示该边缘网络中的所有应用实例对UE提供的IP地址)，边缘网络的服务范围(追踪区列表或小区列表)等)，如向UE提供EES(edge enabler server，EES)的信息(包括EES的名称、IP地址等)。第二服务器可以是边缘网络配置服务器，边缘网络配置服务器负责边缘网络的配置，如向UE提供EES的信息，如EES的IP地址。进一步还可以直接向UE提供应用实例的信息，以及和第一服务器交互获取应用实例的信息，第一服务器可以是域名解析***(domain name system，DNS)服务器。DNS服务器提供主机名和IP地址之间的映射和转换，如果一个服务器总是存在着将某个主机名解析为IP地址的DNS记录，那么该服务器对于该主机来说就是权威性的。DNS是一种用于传输控制协议(transmission control protocol，TCP)/IP应用程序的分布式数据库，它提供主机名和IP地址之间的转换及有关电子邮件的选路信息。这里提到的分布式是指在网络(Internet)上的单个站点不能拥有所有的信息。DNS服务器可以由运营商运营，部署在运营商的网络中。第二服务器还可以是具备第二服务器的功能的其他功能实体。本申请中的名称仅仅是举例说明，对名称不做限定。The second server can provide a resolution service from the application name to the application’s IP address, and can provide the UE with edge network configuration information (such as the name of the edge network, IP address, IP virtual address (used to represent all applications in the edge network) The instance provides the IP address of the UE), the service range of the edge network (tracking area list or cell list, etc.), such as providing EES (edge enabler server, EES) information (including the name of the EES, IP address, etc.) to the UE.

Further, it is possible to directly provide the UE with the information of the application instance, and interact with the first server to obtain the information of the application instance. The first server may be a domain name system (DNS) server. The DNS server provides the mapping and conversion between host names and IP addresses. If a server always has a DNS record that resolves a host name to an IP address, then the server is authoritative for the host. DNS is a distributed database used for transmission control protocol (TCP)/IP applications. It provides conversion between host names and IP addresses and routing information related to emails. The distribution mentioned here means that a single site on the Internet cannot have all the information. The DNS server can be operated by the operator and deployed in the operator's network. The second server may also be another functional entity having the function of the second server. The names in this application are only examples, and the names are not limited.

第三服务器可以是边缘使能服务器。EES可以为部署在边缘网络中的应用实例提供一些使能能力，可以更好的支持应用在MEC的部署情况。可以支持边缘应用的注册、对用户设备(user equipment，UE)的认证和鉴权，为UE提供应用实例的互联网协议(internet protocol，IP)地址信息等。第三服务器还可以是具备第三服务器的功能的其他功能实体。本申请中的名称仅仅是举例说明，对名称不做限定。The third server may be an edge-enabled server. EES can provide some enabling capabilities for application instances deployed in the edge network, and can better support the deployment of applications in MEC. It can support the registration of edge applications, the authentication and authentication of user equipment (UE), and provide the Internet protocol (IP) address information of application instances for the UE. The third server may also be another functional entity having the function of the third server. The names in this application are only examples, and the names are not limited.

应用实例是部署在边缘网络中的应用，也可以称为边缘应用(edge application)、移动边缘计算(mobile edge computing，MEC)应用。一个应用可以同时部署在云和一个或多个边缘网络中，一个应用可以对应多个应用实例。An application instance is an application deployed in an edge network, and may also be called an edge application (edge application) or a mobile edge computing (mobile edge computing, MEC) application. An application can be deployed in the cloud and one or more edge networks at the same time, and an application can correspond to multiple application instances.

UE可以是手机、电脑等设备，UE上可以安装有应用客户端(application client)和边缘使能客户端(edge enabler client，EEC)。应用客户端是边缘应用在UE侧的对等实体。EEC是EES在UE侧的对等实体。The UE may be a device such as a mobile phone or a computer, and an application client (application client) and an edge enabler client (EEC) may be installed on the UE. The application client is the peer entity of the edge application on the UE side. EEC is the peer entity of EES on the UE side.

UE中的应用客户端和边缘网络中的应用实例可以进行应用数据传输(application data traffic),EEC和EES之间可以通过参考点1(edge-1)建立连接，3GPP网络和EES之间可以通过参考点2(edge-2)建立连接，应用实例和EES之间可以通过参考点3(edge-3)建立连接，EEC和边缘网络配置服务器之间可以通过参考点4(edge-4)建立连接。The application client in the UE and the application instance in the edge network can perform application data traffic. The connection between EEC and EES can be established through reference point 1 (edge-1), and the 3GPP network and EES can be connected through Reference point 2 (edge-2) establishes a connection, the application instance and EES can establish a connection through reference point 3 (edge-3), and the EEC and edge network configuration server can establish a connection through reference point 4 (edge-4) .

The method may be applied to a user equipment or a third server, that is, the execution subject of the method may be the user equipment or the third server As shown in Figure 3, the method includes the following steps:

步骤301、获取边缘网络的信息。Step 301: Obtain edge network information.

步骤302、向第一服务器发送第一请求消息，该第一请求消息携带应用的标识和该边缘网络的信息。Step 302: Send a first request message to the first server, where the first request message carries the identifier of the application and the information of the edge network.

步骤303、接收该第一服务器基于该第一请求消息返回的第一响应消息，该第一响应消息携带该边缘网络的信息对应的该应用的应用实例的互联网协议IP地址。Step 303: Receive a first response message returned by the first server based on the first request message, where the first response message carries the Internet Protocol IP address of the application instance of the application corresponding to the edge network information.

可选地，该方法还包括：接收第二服务器或第三服务器的更新指示消息，该更新指示消息用于指示更新该应用的应用实例的IP地址。Optionally, the method further includes: receiving an update instruction message from the second server or the third server, where the update instruction message is used to instruct to update the IP address of the application instance of the application.

该更新指示信息可以发送在301步骤之后，也可在301步骤之前收到。The update instruction information can be sent after step 301 or received before step 301.

可选地，该更新指示消息可以用于指示用户设备的位置发生变化，或，用于指示用户设备所处的边缘网络发生变化，或，用于指示接收方通过发送请求消息以获取更新后的IP地址。Optionally, the update instruction message can be used to indicate that the location of the user equipment has changed, or that the edge network where the user equipment is located has changed, or that the receiver can send a request message to obtain updated information.

By using at least one of the application identifier, uniform resource locator, full domain name, and application name as the identification of the application, the flexibility and reliability of the identification of the application are improved.

步骤902、边缘网络配置服务器在接收到第二请求消息后，根据UE的位置信息，确定UE的位置信息对应的边缘网络的信息。Step 902: After receiving the second request message, the edge network configuration server determines the edge network information corresponding to the location information of the UE according to the location information of the UE.

其中，UE的位置信息对应的边缘网络的信息，可以理解为，距离UE最近的边缘网络的信息，可以是物理位置上的距离，还可以是网络拓扑中的距离。该边缘网络的信息可以用于指示边缘网络的位置，该边缘网络的信息可以理解为UE的另一种位置信息。DN的信息可以是边缘网络的标识，或者边缘网络的位置信息，或者边缘网络的属性信息。边缘网络的信息可以为下述至少一种：边缘网络对应的DNAI、边缘网络的IP地址、EES的IP地址。其中，边缘网络的IP地址或者EES的IP地址可以是IP地址段(地址范围)。边缘网络的IP地址可以是一个虚拟IP地址，可以用于指示部署在边缘网络中的一个或多个应用实例，因为不是应用实例的真实IP地址，因此可以称为虚拟IP地址。通过将边缘网络对应的DNAI、边缘网络的IP地址、第三服务器的IP地址中的至少一种信息作为边缘网络的信息，提高了边缘网络的信息的灵活性和可靠性，使得根据该位置信息获取的应用实例的IP地址可靠性高。Wherein, the information of the edge network corresponding to the location information of the UE can be understood as the information of the edge network closest to the UE, which may be a distance in a physical location or a distance in a network topology. The information of the edge network may be used to indicate the location of the edge network, and the information of the edge network may be understood as another type of location information of the UE.

The information of the edge network may be at least one of the following: DNAI corresponding to the edge network, the IP address of the edge network, and the IP address of the EES. Among them, the IP address of the edge network or the IP address of the EES may be an IP address segment (address range). The IP address of the edge network can be a virtual IP address, which can be used to indicate one or more application instances deployed in the edge network. Because it is not the real IP address of the application instance, it can be called a virtual IP address. By using at least one of the DNAI corresponding to the edge network, the IP address of the edge network, and the IP address of the third server as the information of the edge network, the flexibility and reliability of the information of the edge network are improved, so that according to the location information The IP address of the obtained application instance is highly reliable.

本申请实施例中，边缘网络配置服务器可以保存有UE的位置信息和边缘网络的信息之间的对应关系，这样边缘网络配置服务器可以根据第二请求消息携带的UE的位置信息，查询该对应关系，得到边缘网络的信息，也即是，UE的位置信息对应的边缘网络的信息。例如，边缘网络配置服务器可以维护一个本地数据库，在该本地数据库中存储UE的位置信息和边缘网络的信息之间的对应关系，这样边缘网络配置服务器可以在本地数据库中使用UE的位置信息作为查询的过滤条件，查询到符合该过滤条件的边缘网络的信息。In the embodiment of the present application, the edge network configuration server may store the corresponding relationship between the location information of the UE and the information of the edge network, so that the edge network configuration server can query the corresponding relationship according to the location information of the UE carried in the second request message , Obtain the information of the edge network, that is, the information of the edge network corresponding to the location information of the UE. For example, the edge network configuration server can maintain a local database, and store the correspondence between the location information of the UE and the information of the edge network in the local database, so that the edge network configuration server can use the location information of the UE in the local database as a query The filter condition of, query the information of the edge network that meets the filter condition.

以边缘网络的信息为EES的IP地址为例，边缘网络配置服务器可以根据UE的位置信息，确定EES的IP地址，具体地，边缘网络配置服务器可以根据UE的位置信息，确定对应的DNAI,例如，边缘网络配置服务器可以根据UE的位置信息，查询UE的位置信息和DNAI之间的对应关系，得到DNAI，再根据DNAI，确定EES的IP地址。在一些实施例中，边缘网络配置服务器也可以向EES或会话管理功能(session management function,SMF)订阅UE的用户面管理事件(UE UP change management event)，接收EES或SMF基于订阅返回的该事件的通知信息，通知信息携带DNAI。Taking the information of the edge network as the IP address of EES as an example, the edge network configuration server can determine the IP address of the EES according to the location information of the UE. Specifically, the edge network configuration server can determine the corresponding DNAI according to the location information of the UE, for example, The edge network configuration server can query the corresponding relationship between the location information of the UE and the DNAI according to the location information of the UE to obtain the DNAI, and then determine the IP address of the EES according to the DNAI. In some embodiments, the edge network configuration server may also subscribe to the UE UP change management event (UE UP change management event) from the EES or the session management function (session management function, SMF), and receive the event returned by the EES or SMF based on the subscription. The notification information, the notification information carries DNAI.

针对第二请求消息还携带应用的标识的情况，边缘网络配置服务器可以根据UE的位置信息和应用的标识，确定支持该应用的边缘网络的信息。For the case that the second request message also carries the identification of the application, the edge network configuration server may determine the information of the edge network that supports the application according to the location information of the UE and the identification of the application.

可选地，边缘网络配置服务器还可以确定该边缘网络的信息对应的有效区域信息，该有效区域信息用于指示该边缘网络的信息适用的区域，也即是，该边缘网络的信息在该有效区域信息所指示的区域内有效(valid)，还可以理解为该边缘网络的服务范围。当UE移动出该有效区域信息所指示的区域后，则该边缘网络的信息不再有效，UE需要再次发起第二请求消息，重新获取移动后的位置信息对应的边缘网络的信息。Optionally, the edge network configuration server can also determine the effective area information corresponding to the information of the edge network, and the effective area information is used to indicate the area to which the information of the edge network is applicable, that is, the information of the edge network is in the effective area. Valid in the area indicated by the area information can also be understood as the service range of the edge network. When the UE moves out of the area indicated by the effective area information, the information of the edge network is no longer valid, and the UE needs to initiate a second request message again to obtain the information of the edge network corresponding to the moved location information again.

需要说明的是，步骤901和步骤902是以用户设备从边缘网络配置服务器获取边缘网络的信息为例进行说明，在一些实施例中，该用户设备可以根据该UE的位置信息，从本地存储的边缘网络配置信息中，获取该边缘网络的信息，该边缘网络配置信息包括至少一个边缘网络的信息，该多个边缘网络中包括该边缘网络。通过根据用户设备的位置信息，从多个边缘网络的信息中，获取用户设备的位置信息对应的边缘网络的信息，提供了一种准确快速获取边缘网络的信息的方式。It should be noted that step 901 and step 902 are described by taking the user equipment acquiring edge network information from the edge network configuration server as an example. In some embodiments, the user equipment may store locally based on the location information of the UE. In the edge network configuration information, information about the edge network is acquired, the edge network configuration information includes information about at least one edge network, and the edge network is included in the plurality of edge networks. By obtaining the information of the edge network corresponding to the location information of the user equipment from the information of multiple edge networks according to the location information of the user equipment, it provides an accurate and rapid way to obtain the information of the edge network.

步骤903、边缘网络配置服务器向UE发送第二响应消息，该第二响应消息携带边缘网络的信息。Step 903: The edge network configuration server sends a second response message to the UE, where the second response message carries information about the edge network.

边缘网络配置服务器在确定UE的位置信息对应的边缘网络的信息后，可以将该边缘网络的信息携带在第二响应消息中返回给UE。针对边缘网络配置服务器还可以确定该边缘网络的信息对应的有效区域信息的情况，该第二响应消息中还可以携带该边缘网络的信息对应的有效区域信息。After determining the edge network information corresponding to the location information of the UE, the edge network configuration server may carry the edge network information in a second response message and return it to the UE. For the case where the edge network configuration server can also determine the effective area information corresponding to the edge network information, the second response message may also carry the effective area information corresponding to the edge network information.

通过在基于请求消息返回的响应消息中同时携带边缘网络的信息以及对应的有效区域信息，使得UE能够得知边缘网络的信息适用的区域，从而在该区域内使用该边缘网络的信息获取应用实例的IP地址，提高了应用实例的IP地址获取的准确性。By carrying the information of the edge network and the corresponding effective area information in the response message returned based on the request message, the UE can know the area to which the information of the edge network is applicable, so as to use the information of the edge network in the area to obtain application examples The IP address of the application instance improves the accuracy of obtaining the IP address.

步骤904、UE接收边缘网络配置服务器基于第二请求消息返回的第二响应消息，向DNS服务器发送第一请求消息，该第一请求消息携带应用的标识和边缘网络的信息。Step 904: The UE receives a second response message returned by the edge network configuration server based on the second request message, and sends a first request message to the DNS server, where the first request message carries the identification of the application and the information of the edge network.

UE在获取到边缘网络的信息后，可以将应用的标识和边缘网络的信息携带在第一请求消息中发送给DNS服务器，该第一请求消息用于请求边缘网络的信息对应的该应用的应用实例的IP地址。After obtaining the edge network information, the UE can carry the application identifier and edge network information in a first request message and send it to the DNS server. The first request message is used to request the edge network information corresponding to the application of the application The IP address of the instance.

步骤905、DNS服务器在接收到第一请求消息后，向UE发送第一响应消息，该第一响应消息携带边缘网络的信息对应的该应用的应用实例的IP地址。Step 905: After receiving the first request message, the DNS server sends a first response message to the UE, where the first response message carries the IP address of the application instance of the application corresponding to the edge network information.

本申请实施例中，DNS服务器可以根据第一请求消息携带的应用的标识和边缘网络的信息，确定对应的(匹配的)应用实例的IP地址。具体地，DNS服务器可以保存有应用的标识、边缘网络的信息和应用实例的IP地址之间的对应关系，这样DNS服务器可以根据第一请求消息携带的应用的标识和边缘网络的信息，查询该对应关系，得到应用实例的IP地址，也即是，边缘网络的信息对应的该应用的应用实例的IP地址。In the embodiment of the present application, the DNS server may determine the IP address of the corresponding (matching) application instance according to the application identifier and edge network information carried in the first request message. Specifically, the DNS server can store the correspondence between the application identifier, edge network information, and the IP address of the application instance, so that the DNS server can query the application identifier and edge network information carried in the first request message. According to the corresponding relationship, the IP address of the application instance is obtained, that is, the IP address of the application instance of the application corresponding to the information of the edge network.

例如，边缘网络配置服务器可以维护一个本地数据库，在该本地数据库中存储应用的标识、边缘网络的信息和应用实例的IP地址之间的对应关系，这样DNS服务器可以在本地数据库中，使用应用的标识和边缘网络的信息作为查询的过滤条件，查询到符合该过滤条件的应用实例的IP地址。然后，边缘网络配置服务器可以将该应用实例的IP地址携带在第一响应消息中返回给UE。For example, the edge network configuration server can maintain a local database, and store the correspondence between the identification of the application, the information of the edge network, and the IP address of the application instance in the local database, so that the DNS server can use the application's The identification and edge network information is used as the filter condition for the query, and the IP address of the application instance that meets the filter condition is queried. Then, the edge network configuration server may carry the IP address of the application instance in the first response message and return it to the UE.

需要说明的是，如果该应用在边缘网络中部署了应用实例，则UE获取到的是边缘网络中该应用的应用实例的IP地址，如果应用未在边缘网络中部署应用实例，则UE获取到的可以是云端(中心云)上的该应用的IP地址。It should be noted that if the application has an application instance deployed in the edge network, the UE obtains the IP address of the application instance of the application in the edge network. If the application does not deploy the application instance in the edge network, the UE obtains Can be the IP address of the application on the cloud (central cloud).

可选地，DNS服务器还可以确定该应用实例的IP地址对应的有效区域信息，该有效区域信息用于指示该应用实例的IP地址适用的区域，也即是，应用实例的IP地址在该有效区域信息所指示的区域内有效，当UE移动出该有效区域信息所指示的区域后，则该应用实例的IP地址不再有效。相应地，该第一响应消息中还可以携带该IP地址对应的有效区域信息。Optionally, the DNS server can also determine the valid zone information corresponding to the IP address of the application instance, and the valid zone information is used to indicate the zone to which the IP address of the application instance applies, that is, the IP address of the application instance is valid in this valid zone. The area indicated by the area information is valid. After the UE moves out of the area indicated by the valid area information, the IP address of the application instance is no longer valid. Correspondingly, the first response message may also carry valid area information corresponding to the IP address.

步骤906、UE接收DNS服务器基于第一请求消息返回的第一响应消息。Step 906: The UE receives the first response message returned by the DNS server based on the first request message.

UE在接收到第一响应消息后，可以从该第一响应消息中获取到该应用的应用实例的IP地址，该应用实例的IP地址是UE当前位置对应的应用实例的IP地址。After receiving the first response message, the UE can obtain the IP address of the application instance of the application from the first response message, where the IP address of the application instance is the IP address of the application instance corresponding to the current location of the UE.

步骤901至步骤903是UE获取边缘网络的信息的过程，步骤904至步骤906是UE通过发送第一请求消息和接收第一响应消息，获取到应用的应用实例的IP地址的过程。Steps 901 to 903 are processes for the UE to obtain information of the edge network, and steps 904 to 906 are processes for the UE to obtain the IP address of the application instance of the application by sending a first request message and receiving a first response message.

可选地，UE可以接收边缘网络服务器或EES的更新指示消息，该更新指示消息用于指示更新该应用的应用实例的IP地址。Optionally, the UE may receive an update instruction message from the edge network server or EES, where the update instruction message is used to instruct to update the IP address of the application instance of the application.

在一种可能实现方式中，该更新指示消息还包括更新后的边缘网络的信息，这种情况下，UE获取边缘网络的信息的过程可以包括：接收该更新后的边缘网络的信息。UE接收该更新指示消息的步骤可以在步骤904之前执行，例如，UE在接收到更新指示消息，即接收到更新后的边缘网络的信息后，可以通过步骤904至步骤906来获取更新后的IP地址，该IP地址对应于更新后的边缘网络的信息。该接收更新指示消息的步骤也可以在步骤906之后执行，例如，UE通过步骤301至步骤303，获得该应用的应用实例的IP地址后，如果接收到该更新指示消息，即接收到更新后的边缘网络的信息，则可以再次通过步骤904至步骤906来获取更新后的IP地址，该IP地址对应于更新后的边缘网络的信息。In a possible implementation manner, the update instruction message further includes updated edge network information. In this case, the process of obtaining the edge network information by the UE may include: receiving the updated edge network information. The step for the UE to receive the update indication message may be performed before step 904. For example, after the UE receives the update indication message, that is, after receiving the updated edge network information, it may obtain the updated IP through steps 904 to 906. Address, the IP address corresponds to the updated edge network information. The step of receiving the update instruction message can also be performed after step 906. For example, after the UE obtains the IP address of the application instance of the application through step 301 to step 303, if the update instruction message is received, the updated instruction message is received. For the information of the edge network, the updated IP address can be obtained through step 904 to step 906 again, and the IP address corresponds to the information of the updated edge network.

可选地，该更新指示消息中也可以不包括边缘网络的信息，这种情况下，该接收更新指示消息的步骤可以在步骤901之前执行，例如，UE在接收到更新指示消息后，可以通过步骤901至步骤906来获取更新后的IP地址，该IP地址对应于更新后的边缘网络的信息。该接收更新指示消息的步骤也可以在步骤906之后执行，例如，UE通过步骤901至步骤906，获得该应用的应用实例的IP地址后，如果接收到该更新指示消息，则可以再次通过步骤901至步骤906获取更新后的IP地址，该IP地址对应于更新后的边缘网络的信息。Optionally, the update indication message may not include edge network information. In this case, the step of receiving the update indication message may be performed before step 901. For example, after the UE receives the update indication message, it may pass Steps 901 to 906 are used to obtain the updated IP address, which corresponds to the updated edge network information. The step of receiving the update instruction message can also be performed after step 906. For example, after the UE obtains the IP address of the application instance of the application through step 901 to step 906, if it receives the update instruction message, it can go through step 901 again. Go to step 906 to obtain the updated IP address, which corresponds to the updated edge network information.

在一种可能实现方式中，边缘网络服务器或EES可以监测UE的位置信息，当监测到UE的位置移出步骤902中确定的边缘网络时，边缘网络配置服务器或EES可以向UE发送更新指示消息。在另一种可能实现方式中，UE可以向该第二服务器或该第三服务器发送订阅信息，该订阅信息用于订阅该用户设备对应的边缘网络的变化事件，边缘网络配置服务器或EES可以基于UE订阅的变化事件，当UE对应的边缘网络发生变化时，向UE发送更新指示消息，使得UE接收到该更新指示消息。In a possible implementation manner, the edge network server or EES may monitor the location information of the UE, and when it is monitored that the location of the UE moves out of the edge network determined in step 902, the edge network configuration server or EES may send an update instruction message to the UE. In another possible implementation manner, the UE may send subscription information to the second server or the third server, and the subscription information is used to subscribe to the change event of the edge network corresponding to the user equipment. The edge network configuration server or EES may be based on For the change event subscribed by the UE, when the edge network corresponding to the UE changes, an update indication message is sent to the UE, so that the UE receives the update indication message.

通过向UE发送更新指示消息，使得UE可以在需要访问应用时，重新获取该应用的应用实例的IP地址，提供了一种更新应用实例的IP地址的触发条件，可以保证应用实例的IP地址的可靠性。By sending an update instruction message to the UE, the UE can re-obtain the IP address of the application instance of the application when it needs to access the application, and provide a trigger condition for updating the IP address of the application instance, which can ensure the IP address of the application instance. reliability.

需要说明的是，步骤901至步骤906是以请求-响应(request-response)机制为例进行说明，也即是，发送一个请求消息，接收一个响应消息，在一些实施例中，步骤901至步骤906也可以是订阅-通知(subscribe-notification)机制，也即是，发送一个订阅消息，接收多个通知消息。It should be noted that steps 901 to step 906 are described using a request-response mechanism as an example, that is, a request message is sent and a response message is received. In some embodiments, steps 901 to step 906 may also be a subscription-notification (subscribe-notification) mechanism, that is, one subscription message is sent and multiple notification messages are received.

本申请实施例中，通过UE先与边缘网络配置服务器进行交互，使用UE的位置信息从边缘网络配置服务器中获取边缘网络的信息，然后UE再与DNS服务器进行交互，使用应用的标识和边缘网络的信息从DNS服务器获取对应的应用实例的IP地址，由于该应用实例的IP地址是根据UE的位置信息确定的，是离UE最近的应用实例的IP地址，因此能够满足第三方应用提供商调度的需求。In the embodiment of this application, the UE first interacts with the edge network configuration server, uses the location information of the UE to obtain the edge network information from the edge network configuration server, and then the UE interacts with the DNS server, using the application identifier and the edge network Obtain the IP address of the corresponding application instance from the DNS server. Since the IP address of the application instance is determined according to the location information of the UE, it is the IP address of the application instance closest to the UE, so it can meet the schedule of third-party application providers Demand.

另外，如果DNS服务器没有部署应用实例(边缘应用)，则UE获取到的是中心云上的应用的IP地址，提升了获取的效率，节省了和不同EES交互的信令，提高了应用实例的IP地址获取的准确性。In addition, if the DNS server does not deploy an application instance (edge application), the UE obtains the IP address of the application on the central cloud, which improves the efficiency of acquisition, saves the signaling of interaction with different EES, and improves the performance of the application instance. Accuracy of IP address acquisition.

图9对应的实施例中，UE向边缘网络配置服务器发送的第二请求消息携带UE的位置信息。可选地，该第二请求消息中也可以不携带UE的位置信息，而是携带UE的标识。下面将针对这种情况，在图10对应的实施例中，对应用实例的地址获取方法的步骤进行说明。需要说明的是，图10对应的实施例着重描述与图9对应的实施例的区别之处，而与图9对应的实施例同理的步骤还请参见图9对应的实施例，在图10对应的实施例中不做赘述。In the embodiment corresponding to FIG. 9, the second request message sent by the UE to the edge network configuration server carries the location information of the UE. Optionally, the second request message may not carry the location information of the UE, but instead carry the identity of the UE. In view of this situation, in the embodiment corresponding to FIG. 10, the steps of the address obtaining method of the application example will be described below. It should be noted that the embodiment corresponding to FIG. 10 focuses on the differences between the embodiment corresponding to FIG. 9 and the steps similar to those of the embodiment corresponding to FIG. 9 also refer to the embodiment corresponding to FIG. 9. Details are not described in the corresponding embodiment.

图10是本申请实施例提供的一种应用实例的地址获取方法的流程图，如图10所示，该方法包括下述步骤：FIG. 10 is a flowchart of an address obtaining method of an application example provided by an embodiment of the present application. As shown in FIG. 10, the method includes the following steps:

步骤1001、UE向边缘网络配置服务器发送第二请求消息，该第二请求消息携带该UE的标识。Step 1001: The UE sends a second request message to the edge network configuration server, where the second request message carries an identifier of the UE.

其中，UE的标识可以用于确定UE的位置信息，该第二请求消息用于请求UE的位置信息对应的边缘网络的信息。Wherein, the identifier of the UE may be used to determine the location information of the UE, and the second request message is used to request information of the edge network corresponding to the location information of the UE.

其中，该UE的标识可以为下述至少一种：UE的IP地址、通用公共签约标识符(generic public subscription identifier，GPSI)、移动台综合业务数字网(mobile station integrated services digital network，MSISDN)。通过将用户设备的IP地址、GPSI、MSISDN中的至少一种信息作为用户设备的标识，提高了用户设备的标识的灵活性和可靠性。The identifier of the UE may be at least one of the following: the IP address of the UE, the generic public subscription identifier (GPSI), and the mobile station integrated services digital network (MSISDN). By using at least one of the IP address, GPSI, and MSISDN of the user equipment as the identification of the user equipment, the flexibility and reliability of the identification of the user equipment are improved.

可选地，与步骤901同理，该第二请求消息中还可以携带应用的标识。Optionally, as in step 901, the second request message may also carry an application identifier.

步骤1002、边缘网络配置服务器在接收到第二请求消息后，根据UE的标识，获取UE的位置信息，根据UE的位置信息，确定对应的边缘网络的信息。Step 1002: After receiving the second request message, the edge network configuration server obtains the location information of the UE according to the identifier of the UE, and determines the corresponding edge network information according to the location information of the UE.

本申请实施例中，边缘网络配置服务器根据UE的标识，获取UE的位置信息可以包括下述两种方法：In the embodiment of the present application, the edge network configuration server may obtain the location information of the UE according to the identifier of the UE in the following two methods:

方法1、边缘网络配置服务器根据该UE的标识，向接入及移动性管理功能(serving access and mobility management function,serving AMF)请求该UE的位置信息，接收该AMF基于请求返回的响应消息，该响应消息携带该UE的位置信息。Method 1. The edge network configuration server requests the location information of the UE from the access and mobility management function (serving access and mobility management function, serving AMF) according to the identity of the UE, and receives the response message returned by the AMF based on the request. The response message carries the location information of the UE.

方法2、边缘网络配置服务器根据该UE的标识，向该AMF、第三服务器或者会话管理功能(session management function,SMF)订阅该UE的位置信息，接收该AMF、第三服务器或者SMF基于订阅返回的通知消息，该通知信息中携带该UE的位置信息。如订阅UE的“UE UP change management event”并获取通知信息，通知信息携带UE的位置信息,如UE的DNAI。Method 2. The edge network configuration server subscribes to the location information of the UE from the AMF, the third server or the session management function (SMF) according to the identity of the UE, and receives the AMF, the third server or the SMF and returns based on the subscription The notification message contains the location information of the UE. For example, subscribe to the "UE UP change management event" of the UE and obtain the notification information, which carries the location information of the UE, such as the DNAI of the UE.

边缘网络配置服务器可以向AMF、EES或者SMF订阅该UE的位置信息，接收AMF、EES或者SMF基于订阅返回的通知消息，该通知信息中携带该UE的位置信息。The edge network configuration server may subscribe to the location information of the UE from the AMF, EES or SMF, and receive notification messages returned by the AMF, EES or SMF based on the subscription, and the notification information carries the location information of the UE.

需要说明的是，当第二请求消息是一个订阅的请求消息时，可以理解第二请求消息用于订阅UE对应的边缘网络的信息。当边缘网络配置服务器获知UE的位置信息发生变化时，边缘网络配置服务器判断如果UE的位置对应的边缘网络发生变化，那么边缘网络配置服务器确定UE当前位置对应的边缘网络的信息，并向UE发送基于该订阅请求的通知消息，通知消息携带边缘网络的信息，具体地携带EES的IP地址。这个通知消息可以发送多次。It should be noted that when the second request message is a subscription request message, it can be understood that the second request message is used to subscribe to the information of the edge network corresponding to the UE. When the edge network configuration server learns that the location information of the UE has changed, the edge network configuration server determines that if the edge network corresponding to the location of the UE changes, the edge network configuration server determines the edge network information corresponding to the current location of the UE and sends it to the UE Based on the notification message of the subscription request, the notification message carries the information of the edge network, specifically the IP address of the EES. This notification message can be sent multiple times.

该步骤1002中边缘网络配置服务器根据UE的位置信息，确定对应的边缘网络的信息与步骤902同理，不再赘述。In step 1002, the edge network configuration server determines the corresponding edge network information according to the location information of the UE. The same is true for step 902, and will not be repeated.

步骤1003、边缘网络配置服务器向UE发送第二响应消息，该第二响应消息携带边缘网络的信息。Step 1003: The edge network configuration server sends a second response message to the UE, where the second response message carries information about the edge network.

步骤1004、UE接收边缘网络配置服务器基于第二请求消息返回的第二响应消息，向DNS服务器发送第一请求消息，该第一请求消息携带应用的标识和边缘网络的信息。Step 1004: The UE receives the second response message returned by the edge network configuration server based on the second request message, and sends a first request message to the DNS server, where the first request message carries the identification of the application and the information of the edge network.

步骤1005、DNS服务器在接收到第一请求消息后，向UE发送第一响应消息，该第一响应消息携带边缘网络的信息对应的该应用的应用实例的IP地址。Step 1005: After receiving the first request message, the DNS server sends a first response message to the UE.

步骤1003至步骤1005与步骤903至步骤905同理，不再赘述。Step 1003 to step 1005 are the same as step 903 to step 905, and will not be repeated.

步骤1006、UE接收DNS服务器基于第一请求消息返回的第一响应消息。Step 1006: The UE receives the first response message returned by the DNS server based on the first request message.

本申请实施例中，通过UE先与边缘网络配置服务器进行交互，使用UE的标识从边缘网络配置服务器中获取边缘网络的信息，然后UE再与DNS服务器进行交互，使用应用的标识和边缘网络的信息从DNS服务器获取对应的应用实例的IP地址，其中，边缘网络配置服务器可以根据UE的标识确定UE的位置信息，再根据UE的位置信息确定边缘网络的信息，由于该应用实例的IP地址是根据UE的位置信息确定的，是离UE最近的应用实例的IP地址，因此能够满足第三方应用提供商调度的需求。In the embodiment of this application, the UE first interacts with the edge network configuration server, uses the UE's identity to obtain the edge network information from the edge network configuration server, and then the UE interacts with the DNS server, using the application's identity and edge network information The information obtains the IP address of the corresponding application instance from the DNS server, where the edge network configuration server can determine the location information of the UE according to the UE’s identity, and then determine the edge network information according to the UE’s location information, because the IP address of the application instance is The IP address of the application instance closest to the UE is determined according to the location information of the UE, so it can meet the scheduling requirements of third-party application providers.

图9对应的实施例中，UE先根据UE的位置信息，向边缘网络配置服务器请求边缘网络的信息，UE再根据应用的标识和边缘网络的信息，向DNS服务器请求应用实例的IP地址。在一些实施例中，UE无需与DNS服务器之间进行交互，可以从边缘网络配置服务器获取应用实例的IP地址，下面将针对这种情况，在图11对应的实施例中进行说明。参见图11，该应用实例的地址获取方法可以简述为：UE向边缘网络配置服务器发送第三请求消息，该第三请求消息携带应用的标识和UE的位置信息；UE接收该边缘网络配置服务器基于该第三请求消息返回的第三响应消息，该第三响应消息携带UE的位置信息对应的该应用的应用实例的IP地址。可选地，边缘网络配置服务器向DNS服务器发送第一请求消息，该第一请求消息携带应用的标识和边缘网络的信息；边缘网络配置服务器接收DNS服务器基于第一请求消息返回的第一响应消息，该第一响应消息携带应用实例的IP地址。In the embodiment corresponding to FIG. 9, the UE first requests the edge network information from the edge network configuration server according to the location information of the UE, and then the UE requests the IP address of the application instance from the DNS server according to the application identifier and edge network information. In some embodiments, the UE does not need to interact with the DNS server, and can obtain the IP address of the application instance from the edge network configuration server. This case will be described in the embodiment corresponding to FIG. 11 below. Referring to FIG. 11, the address acquisition method of the application instance can be briefly described as: the UE sends a third request message to the edge network configuration server, the third request message carries the identification of the application and the location information of the UE; the UE receives the edge network configuration server Based on the third response message returned by the third request message, the third response message carries the IP address of the application instance of the application corresponding to the location information of the UE. Optionally, the edge network configuration server sends a first request message to the DNS server, where the first request message carries the identification of the application and the information of the edge network; the edge network configuration server receives the first response message returned by the DNS server based on the first request message , The first response message carries the IP address of the application instance.

如图11中的实线所示，该应用实例的地址获取方法可以基于UE和边缘网络配置服务器之间的交互来实现，如果边缘网络配置服务器保存有UE的位置信息或边缘网络的信息、应用的标识、应用实例的IP地址之间的对应关系，则UE可以直接向边缘网络配置服务器请求应用实例的IP地址。如图11中的实线和虚线所示，该应用实例的地址获取方法可以基于UE和边缘网络配置服务器之间的交互以及边缘网络配置服务器与DNS服务器之间的交互来实现，如果边缘网络配置服务器仅保存有UE的位置信息和边缘网络的信息的对应关系，而没有UE的位置信息或边缘网络的信息、应用的标识、应用实例的IP地址之间的对应关系，则边缘网络配置服务器可以进一步向DNS服务器发送请求消息，来获取应用实例的IP地址后返回给UE。As shown by the solid line in Figure 11, the address acquisition method of this application instance can be implemented based on the interaction between the UE and the edge network configuration server. If the edge network configuration server saves the location information of the UE or the edge network information, application The corresponding relationship between the identifier of the application instance and the IP address of the application instance, the UE can directly request the IP address of the application instance from the edge network configuration server. As shown by the solid and dashed lines in Figure 11, the address acquisition method of this application instance can be implemented based on the interaction between the UE and the edge network configuration server and the interaction between the edge network configuration server and the DNS server. The server only saves the correspondence between the location information of the UE and the information of the edge network, and there is no correspondence between the location information of the UE or the information of the edge network, the identification of the application, and the IP address of the application instance, the edge network configuration server can Further send a request message to the DNS server to obtain the IP address of the application instance and return it to the UE.

下面将针对这两种情况，在图12对应的实施例中，对应用实例的地址获取方法进行说明。需要说明的是，图12对应的实施例着重描述与图9对应的实施例的区别之处，而与图9对应的实施例同理的步骤还请参见图9对应的实施例，在图12对应的实施例中不做赘述。In the following two cases, in the embodiment corresponding to FIG. 12, the address obtaining method of the application example will be described.

步骤1205、DNS服务器向边缘网络配置服务器发送第一响应消息，该第一响应消息携带应用实例的IP地址。Step 1205: The DNS server sends a first response message to the edge network configuration server, where the first response message carries the IP address of the application instance.

步骤1202至步骤1205为可选步骤。Step 1202 to step 1205 are optional steps.

与步骤905同理，DNS服务器还可以确定该应用实例的IP地址对应的有效区域信息，相应地，DNS服务器可以将该有效区域信息携带在第一响应消息中返回给边缘网络配置服务器。Similar to step 905, the DNS server can also determine the effective area information corresponding to the IP address of the application instance. Accordingly, the DNS server can carry the effective area information in the first response message and return it to the edge network configuration server.

步骤1206、边缘网络配置服务器获取应用实例的IP地址。Step 1206: The edge network configuration server obtains the IP address of the application instance.

在一种可能实现方式中，边缘网络配置服务器可以从DNS服务器获取应用实例的IP地址。例如，通过步骤1202至步骤1205，边缘网络配置服务器可以接收到DNS服务器返回的第一响应消息，边缘网络配置服务器可以从DNS服务器返回的第一响应消息中，获取到应用实例的IP地址。In a possible implementation manner, the edge network configuration server may obtain the IP address of the application instance from the DNS server. For example, through step 1202 to step 1205, the edge network configuration server may receive the first response message returned by the DNS server, and the edge network configuration server may obtain the IP address of the application instance from the first response message returned by the DNS server.

在另一种可能实现方式中，边缘网络配置服务器可以自己解析出应用实例的IP地址。例如，通过步骤1201，边缘网络配置服务器可以接收到第三请求消息，根据该第三请求消息携带的应用的标识和UE的位置信息，获取应用实例的IP地址。例如，边缘网络配置服务器可以保存有UE的位置信息、应用的标识和应用实例的IP地址之间的对应关系，边缘网络配置服务器可以根据应用的标识和UE的位置信息，查询该对应关系，得到应用实例的IP地址。可选地，边缘网络配置服务器还可以确定该应用实例的IP地址对应的有效区域信息。In another possible implementation manner, the edge network configuration server can resolve the IP address of the application instance by itself. For example, through step 1201, the edge network configuration server may receive the third request message, and obtain the IP address of the application instance according to the identification of the application carried in the third request message and the location information of the UE. For example, the edge network configuration server may save the corresponding relationship between the location information of the UE, the application identifier and the IP address of the application instance, and the edge network configuration server may query the corresponding relationship according to the application identifier and the location information of the UE, and obtain The IP address of the application instance. Optionally, the edge network configuration server may also determine the effective area information corresponding to the IP address of the application instance.

可选地，边缘网络配置服务器在获取到应用实例的IP地址后，还可以根据获取到的应用实例的IP地址，查找该应用实例的IP地址对应的EES的IP地址，例如，边缘网络配置服务器可以根据获取到的应用实例的IP地址，查询应用实例的IP地址和EES的IP地址之间的对应关系，得到该应用实例的IP地址对应的EES的IP地址。Optionally, after obtaining the IP address of the application instance, the edge network configuration server may also search for the IP address of the EES corresponding to the IP address of the application instance according to the obtained IP address of the application instance, for example, the edge network configuration server The corresponding relationship between the IP address of the application instance and the IP address of the EES can be queried according to the obtained IP address of the application instance, and the IP address of the EES corresponding to the IP address of the application instance can be obtained.

步骤1207、边缘网络配置服务器向UE发送第三响应消息，该第三响应消息携带应用实例的IP地址。Step 1207: The edge network configuration server sends a third response message to the UE, where the third response message carries the IP address of the application instance.

可选地，边缘网络配置服务器还可以将应用实例的IP地址对应的有效区域信息携带在第三响应消息中返回给UE。通过在基于请求消息返回的响应消息中同时携带应用实例的IP地址以及对应的有效区域信息，使得接收方能够得知应用实例的IP地址适用的区域，从而在该区域内使用该应用实例的IP地址，保证了应用实例的IP地址的准确性。Optionally, the edge network configuration server may also carry the effective area information corresponding to the IP address of the application instance in the third response message and return it to the UE. By carrying the IP address of the application instance and the corresponding effective area information in the response message returned based on the request message, the receiver can know the area to which the IP address of the application instance is applicable, so that the IP of the application instance can be used in this area The address ensures the accuracy of the IP address of the application instance.

可选地，边缘网络配置服务器还可以将该应用实例的IP地址对应的EES的IP地址携带在第三响应消息中发送给UE。Optionally, the edge network configuration server may also carry the IP address of the EES corresponding to the IP address of the application instance in a third response message and send it to the UE.

步骤1208、UE接收边缘网络配置服务器基于第三请求消息返回的第三响应消息。Step 1208: The UE receives a third response message returned by the edge network configuration server based on the third request message.

UE在接收到第三响应消息后，可以从该第三响应消息中获取到应用实例的IP地址，该应用实例的IP地址是UE当前位置对应的应用实例的IP地址。After receiving the third response message, the UE may obtain the IP address of the application instance from the third response message, where the IP address of the application instance is the IP address of the application instance corresponding to the current location of the UE.

可选地，UE可以接收边缘配置网络服务器或EES的更新指示消息，该更新指示消息用于指示更新该应用的应用实例的IP地址，可选地，该更新指示消息可以用于指示用户设备的位置发生变化，或，用于指示用户设备所处的边缘网络发生变化，或，用于指示接收方通过发送请求消息以获取更新后的IP地址。UE接收更新指示消息的步骤可以在1201之前执行，例如，UE在接收到更新指示消息后，可以通过步骤1201至步骤1208来获取更新后的IP地址，该IP地址对应于更新后的边缘网络的信息。该接收更新指示消息的步骤也可以在步骤1208之后执行，例如，UE通过执行步骤1201至步骤1208，获得该应用的应用实例的IP地址后，如果接收到该更新指示消息，则可以再次通过1201至步骤1208来获取更新后的IP地址，该IP地址对应于更新后的边缘网络的信息。边缘网络配置服务器或EES向UE发送更新指示消息的两种实现方式在步骤906中已有说明，此处不再赘述。通过向UE发送更新指示消息，使得UE可以在需要访问应用时，重新获取该应用的应用实例的IP地址，提供了一种更新应用实例的IP地址的触发条件，可以保证应用实例的IP地址的可靠性。Optionally, the UE may receive an update indication message from the edge configuration network server or EES. The update indication message is used to indicate to update the IP address of the application instance of the application. Optionally, the update indication message may be used to indicate the user equipment The location changes, or it is used to indicate that the edge network where the user equipment is located has changed, or it is used to instruct the receiver to obtain the updated IP address by sending a request message. The step of receiving the update indication message by the UE may be performed before 1201. For example, after receiving the update indication message, the UE may obtain the updated IP address through steps 1201 to 1208, which corresponds to the updated edge network information. The step of receiving the update instruction message can also be performed after step 1208. For example, after the UE obtains the IP address of the application instance of the application by performing steps 1201 to 1208, if it receives the update instruction message, it can pass 1201 again. Go to step 1208 to obtain the updated IP address, which corresponds to the updated edge network information. The two implementations of the edge network configuration server or the EES sending the update indication message to the UE have been explained in step 906, and will not be repeated here. By sending an update instruction message to the UE, the UE can re-obtain the IP address of the application instance of the application when it needs to access the application, and provide a trigger condition for updating the IP address of the application instance, which can ensure the IP address of the application instance. reliability.

需要说明的是，步骤1201至步骤1208可以是请求-响应(request-response)机制，也可以是订阅-通知(subscribe-notification)机制。如果是订阅-通知机制，步骤1201中UE可以向边缘网络配置服务器发送订阅消息，如果UE的位置信息对应的该应用的应用实例的IP地址或其有效区域信息有更新，则步骤1207中边缘网络配置服务器可以发通知消息给UE，步骤1208中UE可以接收到通知消息。It should be noted that step 1201 to step 1208 may be a request-response (request-response) mechanism or a subscription-notification (subscribe-notification) mechanism. If it is a subscription-notification mechanism, the UE may send a subscription message to the edge network configuration server in step 1201. If the location information of the UE corresponds to the IP address of the application instance of the application or its effective area information is updated, the edge network in step 1207 The configuration server may send a notification message to the UE, and in step 1208, the UE may receive the notification message.
