For example, A and/or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the related objects are in an "or" relationship.

The embodiments of the present application are described below with reference to the accompanying drawings.

Refer to Figure 1, which is a schematic diagram of a system architecture provided by an embodiment of the present application. As shown in Figure 1, the system architecture Including user equipment (UE), core network and EDN.

Among them, there is a general understanding of EDN. EDN only corresponds to one data network, which is a special local data network (local DN). It includes edge enablement functions and can be identified by DNAI and DNN. It is a network logical concept. Another understanding of EDN is that EDN is the equivalent concept of the central cloud. It can be understood as a local data center (geographic location concept), which can be identified by DNAI and can contain multiple local data networks (local DN). . Applications deployed in EDN are called application instances, which specifically refer to a server application (for example, social media software, augmented reality (AR), virtual reality (VR)) deployed on an instance running in EDN ( instance). An application can deploy one or more EAS in one or more EDNs. EASs deployed and running in different EDNs can be considered as different EASs of an application. They can share a domain name, use an IP address, or Use a different IP address. EAS can also be called edge applications (servers), application instances, edge application instances, MEC applications (servers), EAS functions, etc.

The application client (ApplicationClient, AC) is the peer entity of the edge application on the UE side. AC is used by application users to obtain application services from the application server. AC is a client program applied on the UE side. AC can connect to an application server on the cloud to obtain application services, or it can connect to an EAS deployed and running in one or more EDNs to obtain application services.

The edge enablement server (EES) can provide some enabling capabilities for application instances deployed in EDN, and can better support the deployment of applications in MEC. It can support the registration of edge applications, authentication and authentication of UEs, and provide IP address information of application instances for UEs. It can further support obtaining the identification and IP address information of the application instance, and further send the identification and IP address information of the application instance to the edge data network configuration server. EES is deployed in EDN. Generally, an EAS is registered on an EES, or the information of an EAS is configured on an EES through the management system. The EES is called the EES associated with the EAS. The EES controls/manages the EAS registered/configured on the EES. .

The edge-enabled client (EEC) is the peer entity of EES on the UE side. EEC is used to register EEC information and application client information with EES, perform security authentication and authentication, obtain the IP address of EAS from EES, and provide edge computing enabling capabilities to application clients. For example, the EAS discovery service transfers the IP address of EAS Returned to the application client.

The edge configuration server (ECS) is responsible for the configuration of the EDN, such as providing EES information to the UE. It can also directly provide application instance information to the UE, and interact with the application's DNS to obtain application instance information. Further obtain and save application instance and IP address information from other functional entities.

Among them, the application user signs a service agreement with the application provider to provide services to the application user, and the application user communicates through the connection between the application client and EAS by logging in to the application client on the terminal. The enabling client is a middleware layer, usually located in the operating system, or between the application client and the operating system. The application client can obtain the edge enablement service from the enablement client in the form of an application program interface (API).

Here's how to discover T-EES.

Refer to Figure 2, which is a schematic flow chart of a T-EES discovery method provided by an embodiment of the present application. As shown in Figure 2, the method includes:

S201. The S-EES sends a request message to the first ECS or the second ECS. The request message is used to request to obtain T-EES information.

Among them, S-EES is the EES associated with the first ECS. Optionally, the S-EES is an EES managed by the first ECS or an EES registered with the first ECS. That is to say, the EES associated with the first ECS is an EES managed by the first ECS or an EES registered with the first ECS. In other words, if ECS can obtain EES information, it can be considered that ECS Associated with EES. The method by which ECS obtains EES information is not limited here.

It should be pointed out here that the first ECS stores the information of multiple EESs, the identifiers of the data centers to which the multiple EESs respectively belong, and the identifiers of data centers that are related to the data centers to which the multiple EESs respectively belong. One item. This information can be pre-configured into the first ECS, or the above-mentioned multiple EESs can be sent to the first ECS respectively. Optionally, it can be carried in the registration message. Of course, it can also be carried in other messages, which will not be done here. limited.

Similarly, the second ECS stores at least one of the information of multiple EESs, the identifiers of data centers to which multiple EESs respectively belong, and the identifiers of data centers related to the data centers to which multiple EESs respectively belong. This information can be pre-configured into the second ECS, or the above-mentioned multiple EESs can be sent to the second ECS respectively. Optionally, it can be carried in the registration message. Of course, it can also be carried in other messages, which will not be done here. limited.

The first ECS and the second ECS are related. This relationship can be a cooperative relationship or a commercial relationship. This relationship can be understood as the ECSP or PLMN to which the first ECS belongs has signed a cooperation agreement with the ECSP or PLMN to which the second ECS belongs. In the first ECS, this relationship can be indicated by the indication information in the configuration information of the first ECS; in the second ECS, it can be indicated by the fields in the configuration information of the second ECS. That is to say, when there is a cooperation agreement between the ECSP or PLMN to which the first ECS belongs and the ECSP or PLMN to which the second ECS belongs, a field will be added to the configuration information of both the first ECS and the second ECS to indicate the third ECS. There is a cooperation agreement between the ECSP or PLMN to which one ECS belongs and the ECSP or PLMN to which the second ECS belongs. Optionally, the cooperation relationship can be a connection relationship, that is, the first ECS and the second ECS have a connection relationship.

Among them, the T-EES information includes the identification and/or address information of the T-EES. The address information includes at least one of a fully qualified domain name (Fully Qualified Domain Name, FQDN), a uniform resource locator (uniform resource locator, URL), an IP address, etc. The information of each EES in the EES related to the second ECS may also include the above content.

It should be pointed out here that the triggering condition for S-EES to send a request message to the first ECS may be: when the first EES or EAS detects an application context relocation (ACR) event, the first EES or S-EAS decision for ACR. If S-EES decides to perform ACR, S-EES sends a request message to the first ECS; if S-EAS decides to perform EAR, then S-EAS sends an EAS discovery request to S-EES; S-EES receives the EAS discovery request message. Finally, S-EES sends a request message to the first ECS.

S202. The S-EES receives a response message sent by the first ECS or the second ECS, where the response message includes information about the first EES.

The first EES information at least includes T-EES information.

In an example, if the first EES includes information of an EES, the information of the EES is a T-EES. That is to say, the first ECS or the second ECS has selected the T-EES from the EES related to the second ECS. The specific manner in which the first ECS or the second ECS selects the T-EES from the EES related to the second ECS can be found in the relevant descriptions in Figures 3 and 4, and will not be described here. This processing does not require S-EES to select, which can reduce the workload of S-EES, reduce the amount of data transmission, and improve transmission efficiency.

In another example, the information of the first EES includes information of multiple EESs, and the data centers to which the multiple EESs respectively belong are related to the data center to which the S-EES belongs. S-EES selects the information of one EES from the information of multiple ESSs as the T-EES. That is, S-EES selects one EES from multiple EES as T-EES. The selection strategy can be random selection or other selection methods, which are not limited here. The purpose of this processing can reduce the workload of the first ECS or the second ECS.

In a possible embodiment, the response message sent by the first ECS or the second ECS to the S-EES also includes the first The identification of the data center to which EES belongs. It should be noted that the first EES includes at least one EES related to the second ECS, and the identifier of the data center to which the first EES belongs includes at least one identifier of the data center to which the EES related to the second ECS belongs.

It should be understood that the identification of the data center is used to indicate the data center. A data center can include one or more EES.

Optionally, the data center identifier can be a data network access identifier (datanetwork access identifier, DNAI) or EDN identifier. That is, the data center can be an edge data network (EDN), or represented by DNAI.

An EES can correspond to one or more DNAIs.

The S-EES determines the information of at least one EES from the information of the first EES based on the connection information of the S-EES and the identification of the data center to which the first EES belongs. That is, the S-EES determines the information of at least one EES from the information of the at least one EES related to the second ECS based on the connection information of the S-EES and the identification of the data center to which the at least one EES related to the second ECS belongs. At least one data center to which EES belongs is related to the data center to which S-EES belongs. The S-EES determines the information of the T-EES from the information of at least one EES.

In a possible embodiment, the response message sent by the first ECS or the second ECS to the S-EES also includes indication information of the data center to which the first EES belongs, and the indication information of the data center to which the first EES belongs is for the first EES. Whether the data center to which it belongs is related to the data center to which S-EES belongs. It should be noted that the first EES includes at least one EES related to the second ECS, and the indication information of the data center to which the first EES belongs includes at least one indication information of the data centers to which the EESs related to the second ECS belong.

The indication information of the data center may be a first value or a second value. When the indication information of the data center is the first value, it indicates that the data center has a relationship with the data center to which the S-EES belongs. When the indication information of the data center is the second value, it means that the data center has no relationship with the data center to which the S-EES belongs. Optional, the first value is 1 or true, and the second value is 0 or false.

The S-EES determines the information of at least one EES from the first EES information according to the indication information of the data center to which the first EES belongs. That is, the S-EES determines the information of at least one EES from at least one EES related to the second ECS based on the indication information of the data center to which the at least one EES related to the second ECS respectively belongs. The data center to which at least one EES belongs has a relationship with the data center to which S-EES belongs; S-EES determines the information of T-EES from the information of at least one EES.

In the above process, the selection operation is performed by S-EES, which can reduce the workload of the first ECS or the second ECS.

In a possible embodiment, the response message sent by the first ECS or the second ECS to the S-EES also includes connection performance information of the first EES, and the connection performance information of the first EES is used to indicate the relationship between the first EES and the S-EES. or used to indicate the connection performance between the data center to which the first EES belongs and the data center to which the S-EES belongs.

The S-EES determines the information of the T-EES from the information of the first EES based on the connection performance information of the first EES, and the T-EES is an EES whose connection performance information in the first EES satisfies the first preset connection performance.

The connection performance includes at least one of delay, bandwidth, etc., and the first preset connection performance includes at least one of delay less than the first preset delay and bandwidth greater than the first preset bandwidth. Of course, the connection performance information may also include indicators other than delay and bandwidth, which will not be described here.

Further, when at least one EES includes multiple EESs, the S-EES can determine the T-EES from the at least one EES based on the connection performance of the at least one EES, and the T-EES is the connection performance information in the at least one EES that satisfies the first predetermined Assume the connectivity performance of an EES.

In one example, the T-EES is an EES whose connection performance information among at least one EES satisfies the first preset connection performance. Specifically, the T-EES is an EES among at least one EES whose connection performance information satisfies the first preset connection performance. For example, when the connection performance includes delay, T-EES is the EES with the smallest delay among at least one EES; for example, when the connection performance includes bandwidth, T-EES is The EES with the largest bandwidth among at least one EES; for example, when the connection performance includes delay and bandwidth, T-EES is the EES with the smallest delay and the largest bandwidth among at least one EES.

After S-EES obtains the identification and/or address information of T-EES, it can implement communication between S-EES and T-EES based on the identification and/or address information of T-EES, and then complete the application context transfer from S-EES. EES to T-EES migration.

It can be seen that in the solution of this application, S-EES determines T-EES from the second ECS related to the first ECS and obtains the information of T-EES. Due to the lack of SLA, S-EES and T-EES S-EES and T-EES cannot communicate with each other, or even if there is an SLA, there is no connection between S-EES and T-EES, or there is no dedicated line connection between S-EES and T-EES, etc., resulting in poor communication quality. -Communication between EES and T-EES, so that S-EES can send EAS discovery requests to T-EES during application context migration to avoid application context migration failure.
