Description

Method and apparatus for selecting edge-enabled client

Technical Field

The present application relates to the field of communications, and more particularly, to a method and apparatus for selecting an edge-enabled client.

Background

The 3GPP SA6 is conducting application-enabled multi-access EDGE computing (MEC) research and defines an EDGE (EDGE) application architecture. Specifically, the application architecture includes a terminal, an Edge Data Network (EDN), and an Edge Configuration Server (ECS). The EDN includes an edge application and an Edge Enable Server (EES). The terminal includes an application client (application client) and an Edge Enable Client (EEC).

In conventional solutions, the EEC sends an EAS discovery request to the EES, which may be used to request a query for a particular EAS, or a particular class of service EAS, or an application specific EAS, or an EAS used at a particular location. The EES receives the discovery request, authenticates and authorizes the EEC, queries the EAS meeting the conditions, and returns the EAS information to the EES. That is, the ECS may comprehensively consider information such as the location of the terminal, the deployment of the EES, and the application instance supported by the EES when selecting the EES for the terminal. However, with the requirements on performance such as low delay and high availability of edge services, it is crucial to select a suitable EES, and how to further improve the ECS selection to the suitable EES is urgently needed to be solved.

It is understood that the terminal in the embodiment of the present application may be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; can also be deployed on the water surface; it may also be deployed on airborne airplanes, balloons, and satellites. The embodiment of the application does not limit the application scenarios of the wireless access network equipment and the terminal.

Fig. 1 shows an application architecture diagram of an embodiment of the present application. As shown in fig. 1, the application architecture includes a terminal 110, an Edge Data Network (EDN) 120, and an Edge Configuration Server (ECS) 130. The EDN includes an edge application 121 and an Edge Enable Server (EES) 122. The terminal includes an application client (application client)111 and an Edge Enable Client (EEC) 112.

EDN 120：

A common understanding is that an EDN corresponds to a data network, is a particular local data network (local DN), contains edge-enabled functionality, can be identified using a Data Network Access Identifier (DNAI) and a Data Network Name (DNN), and is a network logical concept. Another understanding of the EDN is that the EDN is a peer-to-peer concept of a central cloud, which may be understood as a local data center (i.e., a concept of geographic location), may be identified using DNAI, and may contain a plurality of local data networks (local DNs).

The edge application 121:

an edge application is an application deployed in an edge data network. The edge application may also be referred to as an "application instance". In particular, a server application (e.g., social media software, Augmented Reality (AR), Virtual Reality (VR)) deploys an instance (instance) running on the EDN. An application may deploy one or more EAS in one or more EDNs, where the EAS deployed in different EDNs may be considered different EAS of an application, which may share a domain name or use a different domain name than the application deployed on the cloud, where the domain name may be a Fully Qualified Domain Name (FQDN), may use an arbitrarily played IP address, or may use a different IP address.

It is to be understood that EAS may also be referred to as an edge application (server), an application instance, an edge application instance, a multi-access edge computing (MEC) application (server), an EAS function, and the like.

The application client 111:

an application client is a peer entity of an edge application on the UE side. The application client is used for an application user (user) to obtain application services from the application server. The application client is a client program applied on the terminal side, and the application client can be connected to an application server on the cloud to acquire application services, and can also be connected to an EAS (electronic article surveillance) deployed and operated in one or more EDNs to acquire the application services.

EES 122：

The EES is deployed in the EDN, can provide some enabling capabilities for the application instance deployed in the EDN, can better support the deployment situation of the application in the MEC, can also support registration of the edge application, authentication and authorization of the UE, provides IP address information of the application instance for the UE, and the like, and can further support obtaining the identifier and the IP address information of the application instance, and further sends the identifier and the IP address information of the application instance to the edge data network configuration server. Typically, EAS is registered with or otherwise configured by the management system on an EES, referred to as the EAS associated EES, which controls/manages the EAS registered/configured on the EES.

EEC 112：

The EEC is a peer entity of the EES at the UE side. The EEC is used to register information of the EEC and information of the application client with the EES, perform security authentication and authorization, obtain an IP address of the EAS from the EES, provide an edge computing enabling capability to the application client, such as the EAS discovery server returning the IP address of the EAS to the application client. The EEC may be a sub-functional module implemented inside the AC, or a module integrated in the operating system, or a separate application. .

ECS 130：

The ECS is responsible for the configuration of the EDN, such as providing the UE with information of the EES. The ECS may also directly provide the UE with information of the application instance and interact with the DNS of the application to obtain information of the application instance. And further acquiring and storing information of the application instance and the IP address from other functional entities.

The terms referred to in the present application will be briefly described below.

Load of the EAS:

the EAS load may be a comprehensive representation of the operating states of the EAS system resources, including CPU usage, memory usage, IO usage, number of connections, number of requested connections, bandwidth, etc. When these resources are in operation to a certain extent, it may no longer be possible to provide services to the user or to accept access from new users. At this time, the EAS may be considered overloaded (overload).

It is understood that the loading of different EAS's for the same application may be different and that different EAS's for different applications may be different. That is, different applications may independently count their corresponding EAS load conditions. For example, when the EAS for a first application is overloaded, the EAS for a second application may also be in a normal state.

In conventional solutions, the EEC sends an EAS discovery request to the EES, which may be used to request a query for a particular EAS, or a particular class of service EAS, or an application specific EAS, or an EAS used at a particular location. The EES receives the discovery request, authenticates and authorizes the EEC, queries the EAS meeting the conditions, and returns the EAS information to the EES. It follows that it is important to select the appropriate EES. Therefore, the ECS may comprehensively consider information such as the location of the terminal, the deployment topology of the EES, and the application instance supported by the EES when selecting the EES for the terminal. However, as the requirements for low latency and high reliability of edge services are gradually increased, the requirement for the accuracy of the selected EES is also increased, and how to further improve the ECS to select a suitable EES is urgently needed.

Fig. 2 shows a schematic flow chart of a method of selecting an EES according to an embodiment of the present application.

The ECS obtains load information of each of the plurality of EES for the EAS of the first application, where the load information is used to indicate a load condition of the EAS corresponding to the first application.

In particular, the ECS may actively acquire or passively receive load information for the EAS of the first application for each of the plurality of EES.

It is to be appreciated that an application may deploy one or more EAS in one or more EDNs. That is, one application may have one or more EAS in the same EDN to provide the services of the application. In a plurality of EDNs, each EDN may have one or more EAS of the application providing services of the application.

It is also understood that the plurality of EES may be EES located near the terminal. For example, a distance threshold is preset, and the plurality of EES may be EES with a planar geographic distance from the terminal less than or equal to the distance threshold. Or may also indicate a proximity in the sense of a network communication path, for example, the multiple EES are EES whose communication paths from a cell (cell) where the UE is currently located, a tracking area, and a base station currently serving the UE are less than or equal to the distance threshold. For another example, a delay threshold may be preset, and the delay of the communications between the multiple EES and the UE is smaller than or equal to the EES of the delay threshold.

It may also be appreciated that the ECS passively receiving the load information for the EAS of the first application for each of the plurality of EES may be understood as EES actively sending the load information to the ECS, i.e., the ECS has not sent a request message to the EES requesting the load information prior to receiving the load information. The load information of the EES for the EAS of the first application may also be described as the load information of the EES for the EAS of the first application, which is not limited in this application.

It is also understood that the ECS has configured or obtained the address information of the EES before step 201, for example, the ECS obtains the address information of the EES during the registration process of the EES.

Optionally, the load condition may include a load alarm state or a load normal state.

Specifically, the load alarm state may be understood as a preset load alert threshold reached by the resource usage or occupancy of the EAS, and also indicates that the EAS is not capable of accepting the service requested by the new terminal to use the first application, and the load normal state may be understood as a state below the preset load alert threshold, and also indicates that the EAS is capable of accepting the service requested by the new terminal to use the first application. For example, if the state of the first EES for the EAS of the first application is the load alarm state, it indicates that the EAS in the first EES for the first application cannot accept the connection request or the service request of the new terminal any more.

It is understood that, when an overload occurs to an EAS (e.g., the first EAS of the first application), if a client of the first application that has connected or used the EAS terminates the connection with the EAS or terminates the system resources that use the EAS, the operating status of the EAS resources may change. For example, the operational state of the EAS may be changed to accept more clients of the first application for access or may accept new resource requests by clients of the first application (the operational state may be referred to as an "overload alert release state"). That is, the load normal state may include an overload warning release state.

It is further understood that, in the case that the EAS state of the first EES for the first application is a load alarm state, the EAS state of the first EES for other applications (for example, the second application) may be a load alarm state or a load normal state, which is not limited in this application.

Optionally, the EES is registered with at least one first EAS, the first EAS is used for providing the first application service for the first application EAS, and the load information for the first application EAS may include load condition information of each of the at least one first EAS.

Specifically, the EES may have one or more first EAS registered thereon. Wherein the load information of the EAS for the first application in step 201 may include load condition information of each of the one or more first EAS. In other words, the load information for the first application may include load condition information of each of all EAS corresponding to the first application and registered on the first EES. Wherein the load condition information of the first EAS is used for describing a load condition of the first EAS, and the load condition information of the first EAS may include a load level of the first EAS and a load parameter of the first EAS.

It is understood that the loading information of the EAS for the first application may also be an aggregate of the loading conditions of all EAS corresponding to the first application and registered on the first EES, where the loading information represents the loading conditions of all EAS of the first application as a whole.

Optionally, the load information further comprises a first load level or a first load parameter.

Specifically, the first load level indicates a load level of the EES for the EAS of the first application, which may be an aggregated load level of the load level of each EAS of the one or more EAS of the first application (the second load level, i.e., the load level of the first EAS) to which the EES corresponds (registered at the EES). Or the first load level comprises a load level of each EAS of the one or more EAS of the first application (registered with the EES) to which the EES corresponds (the second load level, i.e., the load level of the first EAS). The following description will be given taking the first load level as an example:

for example, a load level of the EAS of the first application for which the EES is directed, i.e., the first load level, is divided into a load starvation state, a load pre-alarm state, and a load alarm state. Wherein the load starvation state may be a resource sufficiency of the EAS of the first application for which the EES is intended; the load alert state may be that the EAS of the first application for which the EES is intended is relatively resource intensive, but a new user may still be accessed; the load alarm state may be that the EAS of the first application targeted by the EES is not sufficiently resource efficient to access the new subscriber. The specific resource parameter settings corresponding to the resource states of the EAS for the first application by the EES may be configured by a manager of the resources of the EAS.

As another example, the loading condition of the EAS of the first application for which the EES is intended is divided into primary, secondary, and tertiary, etc. Wherein, when the resource occupancy rate (resource occupancy rate is occupied resource/whole resource) is 90% -95% of one level (for example, level1), when the resource occupancy rate is 80% -90% of another level (for example, level2), and when the resource occupancy rate is lower than 80% of another level (for example, level 3).

The first load parameter may be used to describe a detailed loading condition of the EAS for the first application for which the EES is intended. The first loading parameter may be a set of loading parameters aggregated from loading parameters of each EAS (second loading parameter, i.e., loading parameter of the first EAS) of one or more EAS of the first application corresponding to (registered in) the EES. Or the first loading parameter further includes a loading parameter (second loading parameter, i.e., loading parameter of the first EAS) of each of one or more EAS corresponding to (registered in) the EES of the first application. For example, the first load parameter may include a CPU usage status (condition), a memory usage status, an IO usage status, a number of connection users, a number of requested connections, a bandwidth usage status, and the like, which is not limited in this application.

It is understood that the resource occupancy in the embodiment of the present application may be a comprehensive resource occupancy determined by a resource or a combination of multiple resources of at least one of a memory, a storage, and a computer.

The second load level indicates a load level of the individual EAS of the first application, i.e., a respective, independent load level for each EAS descriptive of the first application. The second load level may also be classified into different levels, such as a load starvation state, a load warning state, and a load alarm state. Wherein the load-starvation state may indicate that resources of one EAS of the first application are sufficient; the load alert state may indicate that one EAS of the first application is relatively scarce in resources, but may still access a new user; the load alarm state may indicate that one EAS of the first application is out of resources and cannot access a new user. The specific resource parameter setting corresponding to the resource status of an EASS of the first application may be configured by an administrator of the resources of the EAS.

As another example, the loading condition of an EAS of the first application is divided into primary, secondary, and tertiary, etc. Wherein, when the resource occupancy rate (resource occupancy rate is occupied resource/whole resource) is 90% -95% of one level (for example, level1), when the resource occupancy rate is 80% -90% of another level (for example, level2), and when the resource occupancy rate is lower than 80% of another level (for example, level 3).

The second loading parameter may be used for a detailed loading situation of the individual EAS of the first application, i.e. for describing a respective, independent loading situation of each EAS of the first application, i.e. the loading situation of the first EAS. The second load parameter may include a CPU usage status (condition), a memory usage status, an IO usage status, a number of connection users, a number of requested connections, a bandwidth usage status, and the like, which is not limited in the present application.

In one embodiment, step 201 may specifically be that the ECS receives the load information of the EAS for the first application sent from each of the plurality of EES. Accordingly, each EES transmits load information for the EAS of the first application to the ECS.

Specifically, the ECS may interact with each of the plurality of EES separately to obtain load information of each EES for the EAS of the first application.

Optionally, the ECS may send a first load request to each EES of the plurality of EES, the first load request requesting a load status of the corresponding EES for the EAS corresponding to the first application. The ECS thus receives a response message from the load request sent by each of the plurality of EES, the response message for each load request including corresponding load information.

Specifically, the ECS may request the load information from each of the EES in the plurality of EES first, that is, the EES may send the load information only when the ECS has a demand, thereby saving signaling overhead. Specifically, the ECS sends a load request to each of the plurality of EES to request a load condition of the EAS corresponding to the first application, and receives a response message of the load request including load information to which the corresponding EES responds. That is, the load request is requested at application granularity, and the response message of the received load request includes the load condition of the entire aggregation for the EAS corresponding to the first application.

For example, the ECS sends a first load request to the first EES and receives a response message of the load request to which the first EES responds, the response message of the load request including a load condition of the first EES for the EAS of the first application.

It is understood that the load request and the response message of the load request may be in a single request and response manner, or may be in a subscription and response manner. When based on the subscription and response manner, the load request message may be referred to as load subscription request information, and the response message of the load request is referred to as a load notification message, and specifically, when receiving the first load request, the first EES may immediately feed back the response message of the load request, that is, immediately notify. The first load request carries a time threshold or a trigger condition for requesting load condition feedback, so that the first EES sends a notification message to feed back the load request message when the time threshold is reached or the trigger condition is met after receiving the first load request, which is not limited in the present application.

Optionally, the first load subscription request may include an identification of the first application.

Specifically, the identifier of the first application is used for uniquely identifying the application (application), and may be a Fully Qualified Domain Name (FQDN), so as to distinguish that the load subscription request is a load request for the first application.

It is understood that if there is no registration of the EAS corresponding to the application requested by the ECS on the first EES, the first EES may feed back no information of the first application to the ECS.

It will also be appreciated that if the ECS request is subscribed to load information for multiple applications, the first load subscription request may include a list of identifications of the applications (i.e., FQDN list).

In another embodiment, the ECS may receive load condition information for each EAS in each of the plurality of EES transmitted from the plurality of EES, i.e., respective, independent load condition information for each EAS, and determine load information for the EAS of the first application in the plurality of EES based on the load condition information for each EAS in the each EES. Accordingly, each of the plurality of EES sends load status information of all EAS registered on the EES to the ECS.

Specifically, the ECS may interact with each of the plurality of EES to obtain load condition information of all EAS in each EES (i.e., EAS corresponding to all applications). Further, the ECS may store the correspondence between EAS and EES of different applications, so that the load condition of a certain EES (e.g., the first application) for all EAS corresponding to the certain application (e.g., the first application) can be determined according to the load condition information of all EAS in the certain EES (e.g., the first EES).

Optionally, the ECS sends a second load request to a first EES of the multiple EES, where the second load request is used to request load conditions of EAS corresponding to all applications in the first EES; the ECS receives a response message of a load request from the first EES, wherein the response message of the load request is used for indicating the load condition of EAS corresponding to all applications in the first EES; specifically, in step 201, the load condition of the first EES for the EAS corresponding to the first application may be determined from the response message of the load request.

Specifically, the load information requested by the ECS from each EES is at EES granularity, such that the load request does not need to indicate the load condition of which application the corresponding EAS is requested. For example, the load request does not need to carry the identifier of the first application, which reduces the complexity of signaling and the processing logic of the EES for the load situation. .

It is understood that the load request may be for requesting the load conditions of all EAS in the first EES. Wherein the load condition of each EAS may include a load condition of each EAS corresponding to each application of the plurality of applications.

It will also be appreciated that the ECS may request load information in both ways.

Optionally, the second load request may include an identification of the first application.

Optionally, in the above two embodiments, the EES may also actively report the load information to the ECS.

Specifically, the load information sent by the EES to the ECS may be carried in an EES registration request or an EES update request.

It is further understood that the EES registration request message may also carry an Identity (ID) of the EES. The identifier of the EES may also be access point information of the EES, such as one or a combination of IP address or Uniform Resource Locator (URL), or FQDN of the EES.

It is further understood that the EES may send the load information of each application registered/managed on the EES in a separate message, or send the load information of a plurality of applications registered/managed on the EES in a single message, which is not limited in this application.

It will also be appreciated that the ECS may also send a response message to the EES requesting a message (e.g., a registration request or an update request). The response message may be an EES registration response message, or an EES registration update response message, or a load report response/acknowledgement message applied to the EES, or a load event report response/acknowledgement message applied to the EES, and the like.

In another embodiment, the ECS may directly receive load condition information sent by each of the EAS from the EAS corresponding to the first application, and obtain load information of the EES for the EAS of the first application according to a corresponding relationship of the EAS on an EES. Accordingly, each of the plurality of EAS for the first application may send respective load condition information for the first application to the ECS.

Specifically, the ECS may directly interact with each of the plurality of EAS corresponding to the first application to obtain load condition information for each of the plurality of EAS corresponding to the first application.

It is understood that the EAS devices may all be registered on the same EES.

Optionally, the ECS may also receive a response message of each EAS feedback after sending a load request to the first application corresponding to the multiple EAS, where the response message carries load condition information of the EAS.

In yet another embodiment, the ECS may receive load condition information for each EAS in each of the plurality of EES transmitted from the management plane function and determine load condition information for the EAS corresponding to the first application based on the load condition information for the EAS in each EES. Accordingly, the management plane function may obtain load condition information for each EAS in each of the plurality of EES and send the information to the ECS.

Optionally, the ECS may also send a load request to the management plane function first, and then receive a response message sent by the management plane function for feedback, where the response message carries load condition information of each EAS in each of the multiple EES.

In yet another embodiment, the ECS may further receive load condition information of each EAS of the EAS corresponding to the first application from the management plane entity, and determine load information of each EES of the plurality of EES for the EAS of the first application according to the load condition information of each EAS. Accordingly, the management plane function may obtain load condition information of each of the EAS corresponding to the first application and transmit the load condition information to the ECS.

Specifically, the EAS corresponding to the first application may include EAS respectively registered to different EES. Therefore, the ECS receives the load condition information of each EAS in the EAS corresponding to the first application, and may further determine the load condition of each EES for the EAS of the first application according to the correspondence between the EAS and the EES.

In one embodiment, the load information sent by the EES to the ECS may be that the EAS may actively send load status information to a registered EES (described below with reference to the "first EES" as an example).

Specifically, the EAS may periodically send the load condition information to the first EES, or may send the load condition information to the first EES based on an event trigger. For example, the EAS may send load status information to the first EES upon detecting a change in load.

Optionally, the load condition information may be carried in at least one of an EAS registration request, an EAS load reporting message, or an EAS load event reporting message.

Specifically, the EAS registration request message may be an EAS registration request message or an EAS registration update message. That is, the EAS may carry the load status information during a registration process with the first EES, or during a registration update process with the first EES.

It is to be understood that the load condition information may also be carried by using other messages in other procedures after the EAS is registered in the first EES, which is not limited in this application.

It is also understood that the EAS registration request message may also carry an Identity (ID) of the EAS. The EAS identifier may also be access point information of the EAS, such as an IP address or URL, or FQDN of an application corresponding to the EAS.

It is understood that the EAS marker in the embodiment of the present application may also be an EAS instance marker, and when multiple EAS markers of the first application are registered on one EES, the EAS markers of the same application may be distinguished by the EAS instance marker. The EAS identifier may also be a resource identifier of the EAS for indexing resources allocated by the management system to the EAS, such as an identifier of a container (container) carrying the EAS.

It is further understood that the EAS and the first EES may also agree in advance, and if the load status is a normal load status, the registration request message may not carry the load status information. That is, if the EES does not detect the load condition information in the registration request message, the load condition is a normal load condition.

It will also be appreciated that the EES may also send a response message to the EAS requesting the message. The response message may be an EAS registration response message, or an EAS registration update response message, or an EAS load reporting response/confirmation message, or an EAS load event reporting response/confirmation message.

It is further understood that the EES has configured or acquired address information of the EAS before each of the EES receives the load condition information transmitted by the EAS, for example, the EAS informs the EAS during registration with the EES.

Optionally, the EAS actively reporting the load condition information may specifically be reporting when a preset condition is met.

For example, the EAS is first registered with the first EES; or

The load of the EAS exceeds a first preset threshold; or

The EAS load is below a second preset threshold.

In particular, the first preset threshold may be greater than or equal to the second preset threshold. Wherein the EAS load exceeds a first predetermined threshold, which may be the first predetermined threshold, for a period of time (e.g., setting timer1), the EAS load is considered to exceed the first predetermined threshold. Likewise, the EAS load being below the second predetermined threshold may be below the second predetermined threshold for a period of time (e.g., setting a timer2), the EAS load is considered to be below the second predetermined threshold.

It is understood that the first preset threshold or the second preset threshold may be set for a single resource of the EAS, such as a resource of a storage space, or may be set for a plurality of items of the EAS or even a combination of all the resources (i.e., the first preset threshold may be understood as a set including a plurality of parameter thresholds), or may be an aggregation threshold obtained by setting all resource parameters through a specific algorithm based on a plurality of items of the EAS, which is not limited in this application. For example, the first preset threshold is set for the total resource condition of memory, storage, and computer, or the first preset threshold is a set of three thresholds { memory equal to value1, storage equal to value2, and computer equal to value3 }.

In another embodiment, the EAS transmits a response message to the load request to the first EES upon receiving the load request transmitted by the first EES, the response message to the load request indicating load condition information of the EAS.

Specifically, the EAS may feed back the load condition information to the first EES when the EAS is under a load overload condition, so as to avoid resource waste caused by still sending the unnecessary load condition information, that is, reduce resource overhead.

Accordingly, the first EES may obtain load conditions of the EAS corresponding to the first application.

In one embodiment, the first EES receives load condition information transmitted from each of the plurality of EAS.

Specifically, the first EES may determine a load condition of the first EES for the EAS corresponding to the first application according to the load condition information of each of the plurality of EAS. That is, the first EES may aggregate the overall loading condition of the EAS for the first application.

In one possible implementation manner, the first EES determines that the load condition of the first EES for the EAS corresponding to the first application is a load alarm state if the load condition indicated by the load condition information of each of the plurality of EAS is the load alarm state. Accordingly, the first EES determines that the load condition of the first EES for the EAS corresponding to the first application is a load normal state if the load condition indicated by the load condition information of at least one EAS of the plurality of EAS is the load normal state.

In another possible implementation manner, in a case that the load condition indicated by part of the state information of the plurality of EAS is a load alarm state, the first EES determines that the load condition of the first EES for the EAS corresponding to the first application is the load alarm state. Accordingly, the first EES determines that the load condition of the first EES for the EAS corresponding to the first application is a load normal state if the load condition indicated by all of the load condition information of the EAS is the load normal state.

Optionally, the first EES may further integrate the load condition information of the plurality of first EAS devices to determine that the load information of the EES for the EAS device corresponding to the first application device further includes the number or proportion of EAS devices in the load alarm state.

In another embodiment, the first EES may receive the load status information of the plurality of EAS transmitted from the management plane function.

The first EES sends a load request message to the management plane function, where the message carries identification information of at least one EAS of the first application. The management plane function returns a response message to the load request, wherein the response message carries load condition information of the at least one EAS of the first application.

In another embodiment, the first EES may receive load information for the EAS of the first application from the management plane function.

The first EES sends a load request message to the management plane function, wherein the message carries first application information. The management plane function returns a response message to the load request, wherein the response message carries load condition information of the at least one EAS of the first application. Or

The management plane function may be capable of knowing the load information for the EAS on each EES corresponding to an application or multiple applications.

Optionally, the first EES may also send a load request to the management plane function to request a load condition of the EAS corresponding to the application or applications on the first EES. The management plane function may carry the load information via a response message of the load request, where the load information indicates a load condition of the EAS corresponding to the application or applications on the first EES. Wherein the management plane function may be an Operations Support System (OSS) function or a multi-access edge scheduler (MEAO) function.

202, the ECS determines a target EES from the first EES based on the load information.

Specifically, the EEC may send a service configuration request message to the ECS. For each application, when the ECS receives the service configuration request message, or due to the UE moving, or due to an event such as a request message (application id FQDN) of a target EES of a source EES in a UE context migration event, the ECS determines an EES for each application according to load information applied to the EES. The ECS then sends the selected EES to the EEC or source EES.

It is to be understood that the target EES may be configured to accept a service connection request or a service resource request of a client of the first application, and provide the client of the first application with a service of the first application.

It is to be understood that the ECS may also select the target EES in combination with at least one of a location of the terminal, a deployment of the EES, and an application instance supported on the EES, which is not limited in this application.

It is also understood that the service configuration request message may carry an application identification, such as FQDN, of all accessed applications. And the service configuration request message may carry multiple applications, i.e., multiple application identifications, at a time.

Fig. 3 shows a schematic flow chart of a method of selecting an EES according to another embodiment of the present application.

It is understood that, unless otherwise specified, the same terms used in the embodiment shown in fig. 3 and the embodiment shown in fig. 2 have the same meanings, and are not repeated herein to avoid repetition.

301, the ECS obtains, from the management plane function, load information of each of the plurality of EES for the EAS of the first application, the load information indicating a load condition of each of the plurality of EES for the EAS corresponding to the first application.

Specifically, the ECS may obtain the load information from the management plane function by a single request and response, or may receive the load information by a subscription and notification.

In one embodiment, the ECS may request the management plane function for the loading conditions of the EAS of all applications in each of the plurality of EES. The ECS finds the load condition of the EAS corresponding to the first application from the response message of the received load request.

In another embodiment, the ECS may request a load condition of the EAS for the first application in each of the plurality of EES from the management plane function. Thus, the ECS can directly obtain the load condition of the EES for the EAS corresponding to the first application from the response message of the load request

In yet another embodiment, the ECS may subscribe to the administrative plane function for the load conditions of all EAS of the first application. The ECS may pre-store the correspondence between the EAS and the EES, such that the ECS may determine, according to the correspondence between the EES and the EAS, a load condition of at least one of the EES corresponding to the EAS of the first application.

In yet another embodiment, the ECS may subscribe to the administrative plane function for the load conditions of all EAS of the plurality of applications. The ECS may pre-store correspondence between different EAS and the EES, so that the ECS may determine, according to the correspondence, a load condition of each application of the plurality of applications corresponding to the EAS of the EES, and further obtain a load condition of the EES for the EAS of the first application.

The ECS determines a target EES from the plurality of EES based on load information for the EAS of the first application in the plurality of EES 302.

It is understood that the embodiment shown in fig. 3 can be combined with the various embodiments shown in fig. 2 without logical contradiction, and the present application does not limit the embodiments.

Fig. 4 shows a schematic flow chart of a method of resource management of an embodiment of the application.

It should be noted that, unless otherwise specified, the embodiment shown in fig. 4 has the same meaning as that of the embodiment shown in fig. 3 by the same terms,

the ECS obtains load information of the EES for the EAS of the first application 401.

It is understood that the obtaining of the load information of the EES for the EAS of the first application in step 401 may be in the same manner as that of the embodiment shown in fig. 3, and for avoiding repetition, the detailed description is omitted here.

Optionally, the load information of the EES for the EAS of the first application includes load condition information of each EAS of the first application registered on the EES, or an overall load condition of all EAS of the first application registered on the EES.

Specifically, the EES is registered with one or more EAS. Wherein a portion of the one or more EAS are EAS for a first application. The load information obtained in step 401 may be individual load information for each EAS of the first application or an aggregation result of the individual load information for each EAS of the first application.

Alternatively, the ECS may actively obtain the load information for the EAS of the first application from the EES, that is, the ECS first sends a request for the load information of the EAS for the EAS of the first application to the EES, and receives the information in response to the request. It may also be that the load information for the EAS of the first application is passively received from the EES, i.e. the EES actively sends the information to the ECS, and the ECS has not previously sent a request message to the EES requesting the load information of the EES for the EAS of the first application.

Specifically, for example, the ECS may actively acquire the load information of the EAS for the first application from the EES upon receiving the request message from the EEC or the EES.

In one implementation, the EEC sends a provisioning request message to the ECS, the provisioning request message requesting information of the EES.

Optionally, the configuration request message includes information of the first application. Wherein the information of the first application may be an application identifier of the first application.

Optionally, the service configuration request message may further include an identification of the terminal and/or location information of the terminal.

Specifically, the ECS may determine a first target EES (i.e., the EES in step 401) satisfying the requirement according to the location information of the terminal. For example, the ECS may use an EES capable of providing a service for the terminal indicated by the location information as the first target EES, or use an EES whose service area includes the location indicated by the location information of the terminal as the first target EES.

In another implementation, the source EES sends an EES request message to the ECS requesting information of the first target EES (i.e., the EES in step 401).

Optionally, the EES request message may comprise information of the first application and/or information of an application client.

Optionally, the EES request message may further include an identification of the enabling client and an identification of the terminal.

402, the ECS determines a processing type for performing resource processing on the EAS of the first application corresponding to the EES according to the load information, where the processing type is any one of capacity expansion, capacity reduction, or instantiation.

Specifically, if the load information indicates that the load is in the alarm state, the processing type of the corresponding resource processing may be capacity expansion. If the load information indicates that the load is in a starvation state, the processing type of the corresponding resource processing may be capacity reduction. If the load information indicates that there is no EAS for the first application on the EES, the process type of the corresponding resource process may be instantiated.

The ECS sends a first request message to the management plane function, the first request message including the process type 403.

Specifically, the ECS carries the determined processing type in a first request message and sends the first request message to the management plane function.

Optionally, the first request message may further include information of the first application and location information corresponding to the EES.

Optionally, the first request message may further include identification information of EAS that requires resource processing.

Specifically, in the case that the processing type is expansion or contraction, the first request message may include identification information of the EAS that needs to be resource-processed.

Optionally, the first request may further include load information of the EES for the EAS of the first application, which may include, for example, a load of up to 80%.

The management plane function performs resource handling for the EAS of the first application based on the handling type 404.

Specifically, if the processing type is expansion, the management plane function performs expansion processing on the EAS of the first application. For example, the management plane function may be 20% of capacity at a time, or may be a specific amount of resources (e.g., store value1, CPU value2, memory value3, etc.) at a time.

In one embodiment, the first request message may further include information of the first application and location information, such that step 404 may specifically be performing resource processing on one or more EAS of the first application at the location indicated by the location information according to the processing type.

Specifically, the location information (e.g., DNAI) is used to indicate a location of the EES, and the information of the first application is used to identify the first application. The first application corresponds to one or more EAS. The management plane function may select a portion of the EAS corresponding to the location of the EES from the one or more EAS corresponding to the first application based on the location of the EES in the first request message.

It is understood that the EAS portion may be one or more. For example, the management plane function may expand the EAS that is most heavily loaded, or may separately expand each EAS. The same expansion can be performed for different EAS, or different expansion can be performed, which is not limited in the present application.

In another embodiment, the first request message further includes identification information of the EAS that requires resource handling. Thus, step 404 may be specifically a resource processing of the EAS identified by the EAS identification information according to the processing type.

Specifically, the first request message includes the identification information of the EAS of the first application that needs resource processing, so that the management plane function can directly perform resource processing on the EAS corresponding to the EAS identification.

In one embodiment, the first request message may further include load information of the EES for the EAS of the first application, so that step 404 may specifically be to determine granularity of resource operation according to the load information, for example, when the load is 80%, the EAS is expanded by 20%, and when the load is 90%, the EAS is expanded by 30%.

Optionally, after step 404, the management plane function may send a response message of the first request message to the ECS, where the response message of the first message is used to indicate a processing result of the resource processing. For example, the processing result may be processing success, processing failure, or processing rejection.

Optionally, after step 404, the EAS after resource processing may perform EAS registration or EAS update operations. For example, the expanded EAS or the instantiated EAS may send a registration update message or an EAS registration message to the EES, and send the latest EAS configuration information to the EES. The EES in turn triggers an update of the EES information to the ECS, e.g. if a new application is registered on the EES.

Optionally, the ECS may further receive a second request message of the first device, where the second request message is used to request information of the EES, so that the ECS selects a second target EES according to the second request message, and sends the information of the second target EES to the first device. Wherein the first device may be the first EEC or the first EES.

Specifically, after performing resource processing on the EAS, the ECS may further receive a second request message sent by another device to request information of the EES, so that the ECS may reselect the EES (hereinafter referred to as "second target EES") according to the resource-processed EAS.

It is understood that the other device may be another EEC (different from the first EEC) or another EES (different from the first EES).

It will also be appreciated that the state of the EAS may change after the ECS has resource processed the EAS. For example, the ECS may expand the EAS load condition, which may change from load alarm to normal, or load starvation.

In an embodiment, if the second request message includes the location information of the terminal, the ECS may specifically select the second target EES according to the location information of the terminal.

In another embodiment, if the second request message includes an identifier of the terminal, the ECS may specifically determine the location of the terminal according to the identifier of the terminal, and then select the second target EES according to the location of the terminal.

Alternatively, if the ECS receives the configuration request message sent by the EEC before step 401, the ECS may send a response message of the configuration request to the EEC, where the response message may carry information of the second target EES.

Alternatively, if the ECS receives the EES request message sent by the source EES before step 401, the ECS may send a response message of the EES request message to the source EES.

FIG. 5 is a schematic flow chart diagram of a method of resource management according to another embodiment of the present application.

It should be noted that, unless otherwise specified, the same terms in the embodiment shown in fig. 5 and the embodiment shown in fig. 4 have the same meanings, and this is not limited in the present application for convenience of description.

It should be noted that, in the case that there is no logic conflict, the embodiment shown in fig. 4 may be combined with the embodiment shown in fig. 5, and the present application does not limit this.

501, an EES obtains loading information of the EES for an EAS of a first application.

In one embodiment, the EES may receive the EAS discovery request message sent by the EEC and perform step 501 after receiving the EAS discovery request message. The EAS discovery request message is for requesting EAS information.

Optionally, the EAS discovery request message includes an application identification of the first application.

Optionally, the EAS discovery request message further includes an identification of the terminal and/or location information of the terminal.

In another embodiment, the EES may also be an application context migration message that receives other EES (e.g., referred to as "source EES" below). The application context migration message is used to request information of the EAS.

Optionally, the application context migration message may include an application identification of the first application and/or information of an application client.

Optionally, the application context migration message may further include an identifier of the enabling client and/or an identifier of a terminal, which is the terminal running the application client.

502, the EES determines a processing type for performing resource processing on the EAS of the first application corresponding to the EES according to the load information, where the processing type is any one of capacity expansion, capacity reduction, or instantiation.

503, the EES sends a first request message to the management plane function, the first request message including the processing type.

The management plane function performs resource handling for the EAS of the first application according to the handling type 504.

Optionally, after step 504, the EAS after resource processing may perform EAS registration or EAS update operations. For example, the expanded EAS or the instantiated EAS may send a registration update message or an EAS registration message to the EES, and send the latest EAS configuration information to the EES.

Alternatively, if the EES receives the EAS discovery request message sent by the EEC before step 501, the ECS may send a response message of the EAS discovery request message to the EEC, where the response message may carry information of the second target EES.

Alternatively, if the EES receives the application context migration message sent by the source EES before step 501, the ECS may send a response message of the application context migration message to the source EES.
