[0141] The steps involved in the deployment of the application server provided in the embodiments of the present application are merely examples, and not all steps are necessarily performed, or the content in each information or message is necessarily selected. In use, steps can be added or reduced as needed.

[0142] The same step or the step with the same function or message in different embodiments can be mutually referenced and learned in the embodiments of the present application.

[0143] The system architecture and business scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, as the network architecture evolves and new business scenarios appear, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0144] As shown in FIG. 1, FIG. 1 is an architecture diagram of an edge application server deployment system provided by the embodiments of the present application. The system includes a terminal 110, a core network 120, a first data network 130, and a first server 140.

[0145] The terminal 110 runs an application program. The core network 120 is used to process call processing, data transmission, mobility management and other functions in the network. The first data network 130 is used for data processing and storage. The first server 140 is used for configuration of the first data network 130.

[0146] For example, the first data network 130 can be an edge data network (EDN), which is used to push data processing and storage functions to the edge of the network, i.e., close to the data source or user.

[0147] For example, the first server 140 can be an edge configuration server (ECS), which is used to be responsible for the configuration of the EDN.

[0148] Optionally, as shown in FIG. 1, the terminal 110 includes one or more application clients (ACs) and an edge enabler client (EEC). The application client is a peer entity of the edge application on the terminal side. The application client is used by the application user to obtain application services from the application server. The application client is a client program on the terminal side. The application client can connect to the application server on the cloud to obtain application services, or connect to the EAS deployed and running in one or more EDNs to obtain application services. The edge enabler client is a peer entity of the EES on the terminal side. The EEC is used to register the information of the EEC and the information of the application client to the EES, perform security authentication and authorization, obtain the IP address of the EAS from the EES, and provide the edge computing enabling capability to the application client, such as the EAS discovery service returning the IP address of the EAS to the application client. The application client and the EEC communicate with each other through the edge interface 5. For example, the address information of the EAS is sent to the AC.

[0149] The first network 130 includes at least one edge application server (EAS) and at least one edge enabler server (EES). The EAS and the EES communicate with each other through the edge interface 3. The EESs communicate with each other through the edge interface 5.

[0150] The edge application server and the terminal communicate with each other through the core network to transmit application data.

[0151] In an embodiment of the present application, taking the first data network 130 as an example, the application deployed in the EDN is referred to as an application instance, specifically, an instance of a server application deployed and running in the EDN, such as social media software, augmented reality (AR), virtual reality (VR), etc. One application can deploy at least one EAS in one or more EDNs, and the EASs deployed and running in different EDNs can be considered as different EASs of one application, which can share one domain name, use one address, or use different addresses.

[0152] It is worth noting that the EES is deployed in the EDN. Generally, the EAS is registered to one EES, or the information of the EAS is configured on one EES through a management system. The EES is referred to as the EES associated with the EAS. The EES can control or manage the EAS registered or configured on the EES.

[0153] For example, in FIG. 1, the interface between the EES and the EEC is EDGE-1, the interface between the EES and the core network 120 is EDGE-2, the interface between the ECS and the EEC is EDGE-4, the interface between the EES and the ECS is EDGE-6, the interface between the EAS and the core network 120 is EDGE-7, and the interface between the ECS and the core network 120 is EDGE-8.

[0154] A terminal is a device that allows a user to access network services. In 3GPP standards, the interface between the terminal and the network is a wireless interface.

[0155] A terminal can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication functions; it can also include a subscriber unit, a cellular phone, a smart phone, a wireless data card, a personal digital assistant (PDA) computer, a tablet computer, a wireless modem, a handheld device, a laptop computer, a cordless phone, or a wireless local loop (WLL) station, a machine type communication (MTC) terminal, a user equipment (UE), a mobile station (MS), a terminal device, or a relay user equipment, etc. Among them, the relay user equipment can be, for example, a 5G residential gateway (RG). For ease of description, the above-mentioned user equipment is collectively referred to as a terminal in this application.

[0156] It should be understood that the terminal in the embodiments of the present application can also be an Internet of Things terminal device, a port, a smart factory, railway transportation, logistics, a drone, a self-driving car, and a terminal in various vertical industry application fields such as unmanned aerial vehicles, self-driving cars, control devices and sensors on trains, control devices and sensors deployed in factories, etc.

[0157] In an embodiment of the present application, a user signs a service agreement with a provider of an application, thereby providing the user with a service. The user connects to and communicates with an EAS in the EDN through a login to an AC on the terminal device 110. The EEC is a middleware layer, generally located in the operating system or between the AC and the operating system. The AC can obtain edge-enabled services from the EEC in the form of an application program interface (API).

[0158] Application Context Migration is also involved in edge computing, generally referring to migrating a running application or service from one computing node to another while maintaining the continuity of the service and the consistency of the state. Based on the architecture shown in FIG. 1, the process of application context migration is shown in FIG. 2, specifically including:

[0159] Step 1, detection of application context migration.

[0160] As an example, the detection entity determines that context migration may be needed. For example, the terminal device location changes, or the user plane path of the terminal device is updated, etc.

[0161] Step 2, decision of application context migration.

[0162] As an example, the decision entity determines that context migration is needed according to the detection result of the detection entity.

[0163] Step 3, execution of application context migration.

[0164] As an example, the execution entity transfers the context of the application from the source EAS to the target EAS.

[0165] Optionally, the execution entity is also configured to notify the terminal device of information of the target EAS, and notify the network device that the context migration is complete and the related information of the target EAS.

[0166] For example, address information of the target EAS, routing information corresponding to the target EAS, etc.

[0167] It is worth noting that in the specific implementation, the detection entity, the decision entity, and the execution entity can be the same entity or different entities, which is not limited here.

[0168] Step 4, cleaning work after application context migration.

[0169] For example, the application client initiates a new socket connection to the target EAS, etc.

[0170] In the prior art, the existing standards define the discovery process of EES and EAS, mainly using a two-stage discovery mechanism, i.e., first discovering EES, and then discovering EAS from EES. The specific process is as follows:

[0171] The first step, EEC discovers EES platform from ECS, specifically including:

[0172] Step 1, EEC requests / subscribe EES corresponding to the location of the terminal device from ECS.

[0173] Step 2, EEC receives EES or EDN meeting the conditions of EEC from ECS.

[0174] Step 3, ECS determines the EES meeting the requirements according to the information of EAS and the information of EES.

[0175] For example, ECS selects the EES meeting the requirements for each application according to the information of EAS and data network access identifier (DNAI), in combination with fully qualified domain name (FQDN) and EES configuration information.

[0176] Step 4, EEC acquires the DNAI of EES.

[0177] Step 5, ECS sends one or more EES information to EEC.

[0178] The second step, EEC discovers EAS from EES, specifically including:

[0179] Step 1, EEC sends the information of EAS needing to be accessed to EES.

[0180] Step 2, EES matches the information of registered EAS according to the information of EAS needing to be accessed.

[0181] For example, EES matches the EAS meeting the user's request according to the information of locally registered or online EAS, and the discovery filtering parameter provided by the user. The EAS can be multiple.

[0182] Step 3, EES returns the information of EAS to EEC.

[0183] As an example, EEC can provide the information of EAS to the application client, for the application client to connect to EAS.

[0184] In some related technologies, the EAS can be dynamically instantiated, that is, when the terminal device requests to obtain the available EAS, there is no available EAS on the EES / EDN, at this time the EES can trigger the EAS instantiation to the edge computing service provider management node system (ECSP MnS) based on the demand of the terminal device. The specific implementation is as shown in FIG. 3, which is a method for EAS instantiation provided by the embodiment of the present application, comprising:

[0185] Step 1, the ASP sends a first request message to the ECSP. Correspondingly, the ECSP receives the first request message from the ASP.

[0186] The first request message is used to request to create the MOI of the EAS demand IOC for the EAS deployment process.

[0187] Step 2, the ECSP sends a first response message to the ASP. Correspondingly, the ASP receives the first response message from the ECSP.

[0188] The first response message is used to indicate that the EAS deployment is in progress.

[0189] Step 3, the ECSP analyzes the demand and determines the operation of the EAS VNF instantiation.

[0190] Step 4, the ECSP sends a second request message to the ETSI NFV MANO NFVO. Correspondingly, the ETSI NFV MANO NFVO receives the second request message from the ECSP.

[0191] The second request message is used to request to instantiate the EAS VNF.

[0192] Step 5, the ETSI NFV MANO NFVO sends a first notification message to the ECSP. Correspondingly, the ECSP receives the first notification message from the ETSI NFV MANO NFVO.

[0193] The first notification message is used to indicate the result of the EAS instantiation.

[0194] Step 6, in the case of successful instantiation, the ECSP creates the EAS function IOC.

[0195] Step 7a, the MOI is created for the EAS demand IOC.

[0196] Step 7b, the ECSP sends a second notification message to the ASP. Correspondingly, the ASP receives the second notification message from the ECSP.

[0197] The second notification message is used to indicate that the EAS requirement MOI and the EAS function MOI have been created.

[0198] Step 7c, the ECSP sends a third notification message to the ASP in case of instantiation failure. Correspondingly, the ASP receives the third notification message from the ECSP.

[0199] The third notification message is used to indicate that the EAS requirement MOI instantiation has failed.

[0200] In some related technologies, in order to ensure service continuity planning, application context migration can be performed in advance when it is predicted that the terminal device will move to a predicted location within a certain time. That is, the EES and the EAS are discovered in advance before the terminal device moves to the predicted location, and the application context is migrated from the initial EAS to the target EAS. In this way, when the terminal device moves to the predicted location, the terminal device can be directly connected to the target EAS, thereby reducing the service interruption time.

[0201] As shown in FIG. 4, FIG. 4 is another method for EAS instantiation provided by an embodiment of the present application, which includes the following steps:

[0202] Step 1, the EES maintains a list of EASs that can be instantiated, and the ECS and the target EES obtain time information of EAS instantiation.

[0203] Step 2, the target EES sends a first request message to the ECS. Correspondingly, the ECS receives the first request message from the target EES.

[0204] For example, the first request message is an EES registration request message, which carries the EAS instantiation state and the time required for the corresponding EAS instantiation.

[0205] Optionally, step 3, the initial EAS sends a discovery request message to the initial EES. Correspondingly, the initial EES receives the discovery request message from the initial EAS.

[0206] For example, the discovery request message is an EAS discovery procedure message, which carries an edge application server discovery filter (EAS discovery filter), a terminal device identifier (UE ID), and an application client identifier (AC ID).

[0207] Optionally, the EAS discovery procedure message can also carry service continuity planning indication information and prediction expiration time. The prediction expiration time is used to describe the estimated latest time that the terminal device can arrive at the predicted / expected location or EAS service area, and the ACR type for service continuity planning.

[0208] Step 4, the initial EES sends a second request message to the ECS. Correspondingly, the ECS receives the second request message from the initial EES.

[0209] For example, the second request message is a retrieve T-EES request message, which carries the EAS discovery filter, UE ID, AC ID, service continuity planning indication, and prediction expiration time.

[0210] Step 5, the ECS determines whether an EES corresponding to an EAS that can be instantiated but has not been instantiated can be selected according to the service continuity planning indication, the prediction expiration time, and the time information corresponding to the EAS.

[0211] For example, if the prediction expiration time is less than the time required for instantiation of the EAS, instantiation of the EAS will cause further increase of ACR latency, thereby causing further increase of service interruption latency or time of non-optimal service performance, and thus the EAS that has been instantiated should be selected.

[0212] Step 6, the ECS sends a first response message to the initial EES. Correspondingly, the initial EES receives the first response message from the ECS.

[0213] For example, the first response message is a retrieve T-EES response message, which carries the information of the target EES (T-EES information), including: EAS instantiation indication information (EAS instantiation information), identification of the target EES (T-EES ID), and EES port information (EES endpoint).

[0214] EAS instantiation information can be EAS instantiation (status) information, for example, EAS has been instantiated, or EAS can be instantiated but has not been instantiated.

[0215] Step 7, the initial EES sends a third request message to the target EES. Correspondingly, the target EES receives the third request message from the initial EES.

[0216] For example, the third request message is an EAS discovery request message, which carries an EAS discovery filter, a service continuity planning indication, and a prediction expiration time.

[0217] Step 8, the target EES determines whether to select an EAS that can be instantiated but has not been instantiated according to the prediction expiration time.

[0218] For example, the target EES determines whether to select an EAS that can be instantiated but has not been instantiated according to the received service continuity planning indication, prediction expiration time, and EAS time information corresponding to the EAS. If necessary, EAS instantiation is triggered.

[0219] Step 9, the target EES sends a second response message to the initial EES. Correspondingly, the initial EES receives the second response message from the target EES.

[0220] For example, the second response message is an EAS discovery response message, which carries target EAS information (T-EAS information). The target EAS information can be an EAS profile, which includes an EAS ID and an EAS endpoint. When EAS instantiation is completed, the target EES can send the instantiated EAS information to the initial EES.

[0221] Step 10, the initial EES sends a third response message to the initial EAS. Correspondingly, the initial EAS receives the third response message from the initial EES.

[0222] For example, the third response message is an EAS discovery response message.

[0223] It is worth mentioning that the initial EAS in the embodiment can be replaced by the AC, and the initial EES can be replaced by the EEC.

[0224] However, in the prior art, the maximum time information required for instantiation of the EAS is directly configured on the ECS and the EES, but the deployment time of different EASs on different platforms is different, so if the EES or the EAS is selected according to the maximum time information required for instantiation of the EAS, it is inaccurate. Therefore, when service continuity planning, how to determine the EAS that meets the demand and ensure that the instantiation of the EAS can be completed before the terminal device moves to the predicted location is a problem that needs to be solved urgently.

[0225] Based on this, the embodiment of the application provides a server deployment method, in which the ECS or the EEC determines to select the EES corresponding to the instantiated EAS or the EAS being instantiated according to the instantiation completion time of the corresponding EAS on the EES and the time when the terminal device moves to the target location. The ECS or the EES determines to select the EAS that has been instantiated or the EAS that is being instantiated according to the instantiation completion time of the corresponding EAS on the EES and the time when the terminal device moves to the target location.

[0226] In the embodiment of the application, the specific structure of the execution subject of the server deployment method is not particularly limited by the embodiment of the application, as long as the execution subject can communicate according to the server deployment method of the embodiment of the application by running the program in which the code of the server deployment method of the embodiment of the application is recorded. For example, the execution subject of the server deployment method provided by the embodiment of the application can be a functional module capable of calling and executing a program in a terminal device, or a communication device applied in a terminal device, such as a chip, a chip system, an integrated circuit, etc. These chips, chip systems, and integrated circuits can be arranged inside the terminal device or independent of the terminal device, and the embodiment of the application does not make any limitation. For example, the execution subject of the server deployment method provided by the embodiment of the application can be a functional module capable of calling and executing a program in a configuration server, or a communication device applied in a configuration server, such as a chip, a chip system, an integrated circuit, etc. These chips, chip systems, and integrated circuits can be arranged inside the configuration server or independent of the configuration server, and the embodiment of the application does not make any limitation. For example, the execution subject of the server deployment method provided by the embodiment of the application can be a functional module capable of calling and executing a program in an enabling server, or a communication device applied in an enabling server, such as a chip, a chip system, an integrated circuit, etc. These chips, chip systems, and integrated circuits can be arranged inside the enabling server or independent of the enabling server, and the embodiment of the application does not make any limitation.

[0227] Embodiments of a method for deploying a server are described below. The solutions of the following embodiments can be combined for use without conflict.

[0228] In a possible embodiment of the present application, the configuration server determines the instantiation time information of the at least one application server corresponding to the at least one enabling server. The instantiation time information of the at least one application server can be sent by the enabling server to the configuration server, or the configuration server can determine the instantiation time information of the at least one application server according to the indication information.

[0229] The instantiation time information is time information remaining for the application server to be instantiated. For example, the remaining duration of the instantiation of the application server, or the completion time of the instantiation of the application server.

[0230] For example, the application server 1 has started to be instantiated, and still needs 10 minutes (min) to complete the instantiation, or will complete the instantiation at 10:30.

[0231] The at least one application server can be registered on the enabling server, or the information of the at least one application server can be configured on the enabling server, for example, by means of a network management system.

[0232] For example, the application server 1 (EAS#1) is registered on the enabling server 1 (EES#1), or the information of the application server 1 (EAS#1) is configured on the enabling server 1 (EES#1). It can be understood that the enabling server 1 (EES#1) is the enabling server associated with the application server 1 (EAS#1). Moreover, the enabling server 1 (EES#1) can control or manage the application server 1 (EAS#1) registered or configured on the enabling server 1 (EES#1).

[0233] In a possible implementation manner of the present application, the instantiation time information is determined according to the start time of the instantiation of the application server and / or the execution duration, and the time information corresponding to the instantiation of the application server.

[0234] The start time of the instantiation of the application server indicates the time when the application server starts to execute the instantiation.

[0235] The execution duration of the instantiation of the application server indicates the duration that the application server has executed.

[0236] The time information corresponding to the instantiation of the application server indicates the total / overall / entire duration of the instantiation of the application server. For example, the total time length of the instantiation of the application server from the start to the completion.

[0237] For example, if it is known that the start time of the instantiation of the application server 1 (EAS#1) is 10:00, and the corresponding time information of the instantiation of the application server 1 (EAS#1) is that it takes 30 minutes (min) in total, then the instantiation time information of the application server 1 (EAS#1) is the completion time of the instantiation, which is 10:30.

[0238] For example, if it is known that the execution time of the instantiation of the application server 1 (EAS#1) is 15 min, and the corresponding time information of the instantiation of the application server 1 (EAS#1) is that it takes 30 min in total, then the instantiation time information of the application server 1 (EAS#1) is the remaining time of the instantiation, which is 15 min.

[0239] Case 1: The instantiation time information of the application server is determined by the enabling server.

[0240] In a possible embodiment of the present application, the enabling server determines the instantiation time information of the application server, and the specific method comprises the following steps:

[0241] Step 1: The enabling server receives indication information from the first network management system. The indication information is used to indicate the start time and / or the execution time of the instantiation of the application server.

[0242] In a possible implementation, the first network management system sends the indication information to the enabling server.

[0243] For example, the indication information can be an EAS instantiation in progress message corresponding to the application server, indicating that the instantiation of the application server is in execution.

[0244] Optionally, the indication information can carry the start time of the instantiation of the application server, and / or the execution time of the instantiation of the application server.

[0245] In a possible implementation, the enabling server can determine the start time of the instantiation of the application server and / or the execution time of the instantiation of the application server according to the received EAS instantiation in progress message.

[0246] Optionally, when the first network management system sends the EAS instantiation in progress message to the enabling server, the message can also carry the completion time corresponding to the instantiation of the application server.

[0247] In a possible implementation, the enabling server can determine the time when the application server instantiation is completed according to the received EAS instantiation in progress message. Specifically, the enabling server can determine the time when the application server is completed according to the time when the EAS instantiation in progress message is received and the time information required by the application server instantiation.

[0248] In step 2, the enabling server determines the instantiation time information of the application server according to the indication information and the time length required by the application server instantiation.

[0249] The time length required by the application server instantiation can be configured by the enabling server. The time length required by each application server instantiation can be the same or different.

[0250] For example, the identifier of the application server 1 is EAS ID#1, and the instantiation time of the application server 1 is 10 minutes (min). The identifier of the application server 2 is EAS ID#2, and the instantiation time of the application server 2 is 30 minutes (min).

[0251] Optionally, the instantiation time of the same application server can also be different.

[0252] For example, if the key performance indicator (KPI) of the application server A required by the application program A is high, the instantiation time of the application server A is long. For example, if the KPI is high, the application program A requires more resources (such as image processor units and memory processor units), and therefore the instantiation time of the application server A is long (such as 30 min). If the KPI of the application server A required by the application program A is low, the instantiation time of the application server A is short. For example, if the KPI is low, the application program A requires less resources (such as image processor and memory processor), and therefore the instantiation time of the application server A is short (such as 15 min).

[0253] In a possible implementation, the indication information carries the start time of the application server instantiation and / or the execution time length, and the enabling server determines the instantiation time information of the application server in combination with the time length required by the application server instantiation.

[0254] The enabling server can obtain the execution time length according to the start time of the application server instantiation, and also can obtain the start time according to the execution time length of the application server instantiation.

[0255] For example, the enabling server receives the start time of the instantiation of the application server 1 (EAS#1) as 10:00, and receives the indication information at 10:15, and can obtain that the instantiation has been performed for 15 min. In combination with the time length of 30 min configured by the enabling server for the instantiation of the application server 1 (EAS#1), the instantiation time information of the application server 1 (EAS#1) can be determined as the remaining time length of 15 min, or the completion time of 10:30.

[0256] For example, the enabling server receives the time length of 15 min for the instantiation of the application server 1 (EAS#1), and receives the indication information at 10:15, and can obtain that the start time of the instantiation is 15 min before, that is, 10:00. In combination with the time length of 30 min configured by the enabling server for the instantiation of the application server 1 (EAS#1), the instantiation time information of the application server 1 (EAS#1) can be determined as the remaining time length of 15 min, or the completion time of 10:30.

[0257] In another possible implementation, the indication information carries the completion time corresponding to the instantiation of the application server, and the enabling server determines the instantiation time information of the application server according to the indication information, that is, the remaining time length of the instantiation of the application server, or the completion time of the instantiation of the application server.

[0258] For example, the enabling server receives the indication information, which carries the completion time corresponding to the instantiation of the application server as 10:30, and receives the indication information at 10:15, and can obtain that the remaining time length of the instantiation of the application server is 15 min.

[0259] In another possible implementation, the enabling server can determine the start time of the instantiation of the application server according to the time of receiving the EAS instantiation in progress, and further determine the completion time of the instantiation of the application server or the remaining time information of the instantiation of the application server. Specifically, the instantiation time information of the application server is determined according to the time of receiving the EAS instantiation in progress and the time information corresponding to the instantiation of the application server.

[0260] Optionally, the method provided in the embodiment of the application further includes: step 3, the enabling server sends the instantiation time information of the application server to the configuration server. Correspondingly, the configuration server receives the instantiation time information of the application server from the enabling server.

[0261] In a possible implementation, the enabling server sends a registration request message, such as an EES registration request message, to the configuration server, and the message includes application server first instantiation time information, such as a time point at which application server instantiation is completed.

[0262] Case 2: The instantiation time information of the application server is determined by the configuration server.

[0263] In a possible embodiment of the present application, the configuration server determines the instantiation time information of the application server, and the specific method includes:

[0264] Step 1: The configuration server receives indication information. The indication information is used to indicate a start time point of application server instantiation and / or an execution duration.

[0265] In a possible implementation, the enabling server sends the indication information to the configuration server.

[0266] For example, the indication information can be an EAS instantiation in progress message corresponding to the application server, indicating that the application server instantiation is being executed.

[0267] Optionally, the indication information can carry a start time point of the application server instantiation and / or an execution duration of the application server instantiation.

[0268] In a possible implementation, the configuration server can determine a start time point of the application server instantiation and / or an execution duration of the application server instantiation according to the received EAS instantiation in progress message.

[0269] Optionally, when the enabling server sends the EAS instantiation in progress message to the configuration server, the message can also carry a completion time point corresponding to the application server instantiation and / or a remaining duration corresponding to the application server instantiation.

[0270] In another possible implementation, the configuration server can determine a start time point of the application server instantiation according to a time point of the received EAS instantiation in progress, and further determine a completion time point of the application server instantiation or a remaining time information of the application server instantiation. Specifically, the instantiation time information of the application server is determined according to a time point of the received EAS instantiation in progress and time information corresponding to the application server instantiation.

[0271] Optionally, in another possible implementation, the first network management system sends indication information to the configuration server. The configuration server determines the instantiation time information of the application server according to the indication information and a time length required for the application server instantiation.

[0272] The difference between the case 1 and the case 2 is that the time length required for the application server instantiation in the case 2 is configured by the configuration server.

[0273] The specific implementation is described with reference to the embodiment of determining the instantiation time information of the application server by the enabling server, which will not be repeated here.

[0274] In one possible embodiment of the present application, the configuration server or the terminal can determine at least one enabling server according to the information of at least one application server instantiation, the first time information of at least one application server instantiation, and the second time information. The enabling server deploys the application server providing services for the terminal device.

[0275] The information of at least one application server instantiation includes the state information of each application server instantiation corresponding to the identification of the application server. The state information of the application server instantiation is used to indicate the state of the application server instantiation.

[0276] For example, the state information of the application server instantiation can include the following: already instantiated, instantiable but not instantiated yet, and instantiation in progress.

[0277] The second time information is used to indicate the time when the terminal device reaches the target location.

[0278] For example, the enabling server obtains the expected location information of the terminal device according to the information provided by the terminal device and the core network function. The information provided by the terminal device can include the AC schedule, the expected AC geographic service area, the expected AC service KPI, and the preferred ESCP list. Optionally, the expected location information of the terminal device further includes corresponding time information.

[0279] It is worth mentioning that in the business continuity planning, the application context can be copied and sent from the initial application server to the target application server before the terminal device moves to the expected location. In this case, the service context in the initial application server is transferred to the target application server and continuously updated until the application client in the terminal device establishes a connection with the target application server. After the terminal device moves to the expected location, the application client on the terminal device can disconnect the connection with the initial application server and directly connect to the target application server.

[0280] Case 1, the configuration server determines at least one enabling server according to the instantiation state information of the application server, the first time information of the application server instantiation and the second time information.

[0281] In a possible implementation, the method comprises:

[0282] Step 1, the configuration server receives a first request message. The first request message is used to request to discover an enabling server.

[0283] For example, the terminal device sends the first request message to the configuration server.

[0284] The first request message comprises the identification of the application server and the second time information.

[0285] Optionally, the first request message further comprises at least one of the identification of the terminal device, the location information of the terminal device and the application information. The application information comprises an access controller (AC) profile, and the AC profile comprises the identification of the AC, the service key performance indicator (KPI) required by the AC and the identification of at least one corresponding application server (for example, a list of EAS IDs).

[0286] For example, the first request message comprises at least one of expected expired time and prediction expiration time, which are used to indicate the estimated time when the terminal device can arrive at the predicted / expected terminal device location or the service area of the application server. The expected expired time is used to indicate the expected end time, for example, the expected time when the terminal device arrives at location 1 is 10:30; the prediction expiration time is used to indicate the expected time length, for example, the expected time length when the terminal device arrives at location 1 is 30 min.

[0287] In a possible implementation, the first request message can be a service provisioning request message or an EES discovery request message. The specific bearer message is not limited in the embodiments of the present application.

[0288] Step 2, the configuration server determines at least one enabling server.

[0289] The configuration server can determine the at least one enabling server according to the state information of instantiation of the at least one application server corresponding to the at least one enabling server, the first time information and the second time information. The application server deployed on the at least one enabling server can complete instantiation before the terminal device reaches the target location; the configuration server can also directly determine the at least one enabling server without screening. The following describes two cases:

[0290] Case 1), the configuration server determines the first enabling server according to at least one of the state information of instantiation of the at least one application server corresponding to the at least one enabling server, the first time information and the second time information.

[0291] In a possible implementation, the identifiers of the application servers in the first request message all correspond to the application servers in the process of executing instantiation, and the configuration server determines the first enabling server according to the first time information and the second time information of instantiation of the application servers.

[0292] As an example, the configuration server can determine the first enabling server according to the remaining duration of instantiation of the application servers in combination with the second time information.

[0293] For example, the first time information is the remaining duration of instantiation of the application servers. The remaining duration of instantiation of the application server 1 corresponding to the enabling server 1 is 15 min, and the remaining duration of instantiation of the application server 2 corresponding to the enabling server 2 is 5 min. The terminal device is expected to reach the location 1 after 5 min, and based on this, the configuration server determines that the application server 2 corresponding to the enabling server 2 can satisfy the completion of instantiation when the terminal device reaches the target location, and determines that the enabling server 2 is the first enabling server.

[0294] As an example, the configuration server can determine the first enabling server according to the completion time of instantiation of the application servers in combination with the second time information.

[0295] For example, the completion time of the instantiation of the application server corresponding to the enabling server 1 is 10:30, and the completion time of the instantiation of the application server corresponding to the enabling server 2 is 10:15. The terminal device is expected to arrive at the position 1 at 10:15, and based on this, the configuration server determines that the application server corresponding to the enabling server 2 can satisfy the terminal device to complete the instantiation when arriving at the target position, and then determines that the enabling server 2 is the first enabling server.

[0296] In another possible implementation, the identification of the application server in the first request message corresponds to different state information of the instantiation of the application server, and the configuration server determines the first enabling server according to the state information of the instantiation of the application server corresponding to the application server, the first time information and the second time information.

[0297] As an example, the configuration server can determine the first enabling server according to the state of each application server.

[0298] For example, the instantiation of the application server corresponding to the enabling server 1 has been completed, and the instantiation of the application server corresponding to the enabling server 2 is being performed. Since the quality of service of the application server 1 is poor, the configuration server determines that the enabling server 2 is the first enabling server.

[0299] As an example, the configuration server can determine the first enabling server according to the state of each application server and the remaining time or completion time of the instantiation, in combination with the second time information.

[0300] For example, the instantiation of the application server corresponding to the enabling server 1 needs 10 min, but has not started to be performed, the instantiation of the application server corresponding to the enabling server 2 needs 30 min to be completed, and the instantiation has been triggered to be performed 15 min ago, that is, the remaining time of the instantiation of the application server 2 is 15 min. The terminal device arrives at the position 1 after 10 min, and based on this, since the instantiation of the application server 1 has not started, but only needs 10 min to be completed, and the instantiation of the application server 2 has started, but still needs 15 min to be completed, the configuration server determines that the enabling server 2 is the first enabling server.

[0301] For example, the instantiation of the application server 1 corresponding to the enabling server 1 is completed, the instantiation of the application server 2 corresponding to the enabling server 2 is being performed, and the instantiation of the application server 3 corresponding to the enabling server 3 has not yet started. The instantiation of the application server 2 needs 30 min, and the execution is triggered 15 min ago. The instantiation of the application server 3 needs 20 min. The terminal device is expected to arrive at the location 1 after 15 min, and the configuration server first determines whether the service quality of the application server 1 meets the requirement. If the service quality of the application server 1 is poor, the configuration server determines that the enabling server 2 is the first enabling server. If the service quality of the application server 1 meets the requirement, the configuration server determines that the enabling server 1 is the first enabling server.

[0302] Case 2), the configuration server directly determines at least one enabling server.

[0303] In this case, the configuration server does not perform screening, or the configuration server determines at least one enabling server as a candidate enabling server according to the prior art.

[0304] Step 3, the configuration server sends a first response message to the first device. Correspondingly, the first device receives the first response message from the configuration server.

[0305] In a possible implementation, when the configuration server determines the first enabling server, the first response message includes information of the first enabling server, and / or an identifier of an application server corresponding to the first enabling server. The information of the first enabling server includes identifier information of the first enabling server, and / or address information of the first enabling server.

[0306] For example, the configuration server sends, to the first device, at least one of address information (EES address) of the first enabling server, identifier information of the first enabling server, and an identifier (EAS ID) of an application server corresponding to the first enabling server.

[0307] In another possible implementation, when the configuration server determines at least one enabling server, the first response message includes at least one of information of the first enabling server, an identifier of an application server corresponding to the first enabling server, and first time information corresponding to the identifier of the application server. The information of the first enabling server includes identifier information of the first enabling server, and / or address information of the first enabling server. The first time information corresponding to the identifier of the application server is used by the first device to determine the first enabling server.

[0308] Case 2, the terminal device determines at least one enabling server according to the instantiation state information of the application server, the first time information of the instantiation of the application server, and the second time information.

[0309] In a possible implementation, the method comprises:

[0310] Step 1, the first device sends a first request message to the configuration server. Correspondingly, the configuration server receives the first request message from the first device.

[0311] The first request message comprises the identifier of the application server and the second time information.

[0312] The specific implementation manner of the configuration server determining the at least one enabling server is described in the foregoing embodiments, and will not be described herein again.

[0313] Step 2, the first device receives a first response message from the configuration server.

[0314] The first response message comprises at least one of the information of the at least one enabling server, the identifier of the application server corresponding to the enabling server, and the first time information corresponding to the identifier of the application server. The information of the enabling server comprises the identifier information and / or the address information of the enabling server. The first time information corresponding to the identifier of the application server is used for the terminal device to determine the first enabling server.

[0315] In a possible implementation, the first response message is a service provisioning request message, which comprises the address information (list of EES address) of the at least one enabling server, the identifier (EAS ID) of the application server corresponding to the address information of the at least one enabling server, the EAS instantiation in progress message corresponding to the identifier of the application server, and the first time information of the application server instantiation.

[0316] Step 3, the first device determines the at least one enabling server according to the first time information of the application server instantiation and the second time information.

[0317] The implementation manner of the first device determining the at least one enabling server is described in the foregoing embodiments, and will not be described herein again.

[0318] In a possible embodiment of the present application, after the enabling server determines the first time information of the application server instantiation, the method further comprises: the enabling server or the terminal device determines a first application server according to the information of the at least one application server instantiation, the first time information of the application server instantiation, and the second time information. The first application server is used to provide services for the terminal device.

[0319] Case 1, the enabling server determines the first application server according to the instantiation state information of the application server, the first time information of instantiation of the application server, and the second time information.

[0320] In a possible implementation, the method comprises:

[0321] Step 1, the enabling server receives a second request message from the first device. The second request message is used to obtain information of the application server.

[0322] For example, the first device sends the second request message to the enabling server.

[0323] The second request message comprises at least one of the following: identification information of the terminal, location information of the terminal, and application information. The application information comprises an AC profile, and the AC profile comprises an identification of an AC, a service KPI required by the AC, and a list of EAS IDs.

[0324] In a possible implementation, the second request message can be a service provisioning request message or an EES discovery request message. The specific carrying message is not limited in the embodiment of the application.

[0325] The second request message comprises second time information, and the second time information is used to indicate a time at which the terminal device arrives at the target location.

[0326] For example, the first request message comprises at least one of the following: expected expired time and prediction expiration time, which are used to indicate an estimated time at which the terminal device can arrive at the predicted / expected terminal device location or the service area of the application server. For specific examples, refer to step 1 in the embodiment of determining the at least one enabling server according to the instantiation state information of the application server, the first time information of instantiation of the application server, and the second time information of the configuration server, which is not repeated here.

[0327] Step 2, the enabling server determines the first application server according to the instantiation state information corresponding to the at least one application server, the first time information, and the second time information.

[0328] For specific examples, refer to case 1) in step 2 in the embodiment of determining the at least one enabling server according to the instantiation state information of the application server, the first time information of instantiation of the application server, and the second time information of the configuration server, the difference being that the first application server is determined by the enabling server in the embodiment, and the first enabling server is determined by the configuration server in the above embodiment.

[0329] Step 3, the enabling server sends second response information to the terminal device. Correspondingly, the terminal device receives the second response information from the enabling server.

[0330] The second response information includes information of the application server. The information of the application server includes identification information of the application server and / or address information of the application server.

[0331] For example, the second response information is an EAS discovery response message, which includes address information of the application server, such as EAS address.

[0332] Case 2, the first device determines the first application server according to the instantiation state information of the application server, the first time information of the instantiation of the application server, and the second time information.

[0333] In a possible implementation, the method comprises:

[0334] Step 1, the first device sends a second request message to the first enabling server. Correspondingly, the first enabling server receives the second request message from the first device. The second request message is used to discover the first application server.

[0335] The specific implementation is the same as the step 1 in the above method in which the first enabling server determines the first application server according to the instantiation state information of the application server, the first time information of the instantiation of the application server, and the second time information, and details are not repeated here.

[0336] Step 2, the first device receives a second response message from the first enabling server. The second response message is used to indicate information of the first application server.

[0337] For example, the first enabling server sends the second response message to the first device.

[0338] The second response information includes identification of the application server corresponding to the address of the first application server, state information of the application server corresponding to the identification of the application server, and the first time information of the instantiation of the application server.

[0339] Step 3, the first device determines the first application server from one or more application servers according to the instantiation time information of the one or more application servers provided by the first enabling server, the second time information, and the instantiation state information of the one or more application servers.

[0340] The terminal determines the specific implementation of the first application server according to the instantiation state information of the first application server, the instantiation time information of the application server and the second time information, as described above in step 2 of the case 1 of the method for determining at least one enabling server, and the difference is that the first device determines the first application server in this embodiment, and the configuration server determines the first enabling server in the above embodiment.

[0341] Step 4: The first device sends the information of the first application server to the first enabling server. Correspondingly, the first enabling server receives the information of the first application server from the terminal device.

[0342] The information of the first application server includes the identification information of the first application server and / or the address information of the first application server.

[0343] For example, the first device sends the EAS information provisioning procedure to the enabling server, which includes the information of the first application server, such as the EAS address.

[0344] In this application, the configuration server and the enabling server first determine the time information of the instantiation of the application server, that is, the remaining time length of the instantiation of the application server or the completion time of the instantiation of the application server. The configuration server or the terminal device determines at least one enabling server according to the time information of the instantiation of the application server and the second time information, that is, the expected time information of the terminal device reaching the target position. The enabling server or the terminal device determines the application server for providing services for the terminal device according to the time information of the instantiation of the application server and the second time information.

[0345] As shown in FIG. 5, FIG. 5 shows a method for deploying an application server provided by an embodiment of the present application, which includes:

[0346] Step 501: The configuration server obtains the first time information of the instantiation of at least one application server corresponding to at least one enabling server.

[0347] The first time information can be determined by the configuration server, or determined by the enabling server and then sent to the configuration server.

[0348] The specific implementation manner is described above in the implementation manner of the configuration server determining the first time information of the instantiation of at least one application server corresponding to at least one enabling server, which will not be described here.

[0349] Step 502: The first device sends a first request message to the configuration server, and correspondingly, the first device receives the first request message from the first device.

[0350] The first device can be a terminal or a source-enabled server. The source-enabled server is an enabling server associated with a first application server providing services for the terminal at a current location. The first request message includes the first identifier and the second time information. The second time information indicates time information of the terminal reaching a target location. The first request message requests to discover the enabling server associated with the first application server identified by the first identifier. Alternatively, the first request message requests to discover the enabling server associated with the first application server identified by the first identifier, which is instantiated before the time indicated by the second time information. The first application server is an application server providing services for the terminal when the terminal is at the target location.

[0351] In step 503a, the configuration server determines the at least one enabling server or the first enabling server according to at least one of the instantiation state information, the instantiation time information of the at least one application server corresponding to the at least one enabling server, and the second time information.

[0352] The first application server associated with the at least one enabling server or the first enabling server is instantiated before the terminal reaches the target location. It can be understood that the first application server associated with the at least one enabling server or the first enabling server can be an application server that has been instantiated or an application server that is being instantiated, but the application server can be instantiated before the terminal reaches the target location.

[0353] The instantiation state information of the application server can be that the application server has been instantiated or is being instantiated, or is an EAS that can be instantiated but has not been instantiated.

[0354] The specific implementation manner is described above with reference to the implementation manners of steps 1-3 of the configuration server determining the at least one enabling server according to the instantiation state information of the application server, the first time information of the instantiation of the application server, and the second time information, and will not be described here.

[0355] It is worth noting that if the configuration server determines the information of the first enabling server in step 503a, step 504a is performed. If the configuration server determines the information of the at least one enabling server in step 503a, step 503b is performed.

[0356] It is worth noting that the at least one enabling server can be all or part of one or more enabling servers. The one or more enabling servers are the enabling servers associated with the configuration server. The configuration server can not have the second time information when determining the at least one enabling server.

[0357] Step 504a, the configuration server sends the first response information to the first device. Correspondingly, the first device receives the first response information from the configuration server.

[0358] The first response message includes the first enabling server information. The first enabling server information includes an identifier of the first enabling server and / or an address of the first enabling server. The first application server associated with the first enabling server is an enabling server instantiated before the terminal reaches the target location.

[0359] Step 503b, the configuration server sends the first device information of at least one enabling server. Correspondingly, the first device receives the information of at least one enabling server from the configuration server.

[0360] The enabling server information includes an identifier of an application server corresponding to the enabling server, state information of the application server corresponding to the identifier, and first time information of instantiation of the application server.

[0361] Step 504b, the first device determines the first enabling server according to at least one of the instantiation state information of at least one application server associated with the at least one enabling server, the instantiation time information, and the second time information.

[0362] The specific implementation method is described above with reference to the implementation method of steps 1-3 of the terminal device determining at least one enabling server according to the instantiation state information of the application server, the first time information of instantiation of the application server, and the second time information, which will not be described here.

[0363] In the embodiments of the present application, after the configuration server or the first device determines the first enabling server, the first enabling server or the first device can determine the first application server according to the instantiation time information of instantiation of the application server and the second time information. As shown in FIG. 6, the specific method includes:

[0364] Step 601, the first enabling server receives a second request message from the first device, and the second request message requests the first enabling server to discover the first application server associated with the first identifier.

[0365] The second request message includes the second time information and the first identifier, and the second time information is used to indicate the time when the terminal reaches the target location. Specifically, the second request message requests the first enabling server to discover the first application server that has completed instantiation before the first terminal reaches the target location.

[0366] In one possible implementation of the present application, after the first enabling server receives the second request message from the first device, the method includes:

[0367] Step 602a, the first enabling server determines the first application server from the one or more application servers according to the instantiation state information of the one or more application servers associated with the first enabling server, the instantiation time information and the second time information.

[0368] Wherein, the first application server completes instantiation before the terminal reaches the target location.

[0369] The specific implementation method refers to the implementation method of steps 1-3 of the enabling server determining the first application server according to the instantiation state information of the application server, the first time information of the instantiation of the application server and the second time information in the above-mentioned embodiments, which will not be repeated here.

[0370] Step 603a, the first enabling server sends second response information to the first device. Correspondingly, the first device receives the second response information from the first enabling server.

[0371] Wherein, the second response information includes the information of the first application server. The information of the first application server includes the identification information of the first application server, and / or the address information of the first application server.

[0372] In another possible implementation of the present application, after the first enabling server receives the second request message from the first device, the method comprises:

[0373] Step 602b, the first enabling server sends third response information to the first device. Correspondingly, the first device receives the third response information from the first enabling server.

[0374] Wherein, the third response information includes the information of at least one application server and the instantiation state information of the at least one application server and the instantiation time information of the at least one application server. Wherein, the at least one application server can be all or part of the one or more application servers. For example, the first enabling server can provide the instantiation state information of the one or more application servers and the instantiation time information of the at least one application server to the first device according to the second request message, or select at least one application server from the one or more application servers, and then provide the instantiation state information of the at least one application server and the instantiation time information of the at least one application server. For example, the at least one application server can be one or more application servers that can complete instantiation before the terminal reaches the target location.

[0375] Step 603b, the first device determines the first application server according to the instantiation state information, the instantiation time information and the second time information of the at least one application server. The first application server is completed instantiation before the terminal reaches the target position.

[0376] The specific implementation method refers to the implementation method of steps 1-4 of the terminal determining the first application server according to the instantiation state information of the application server, the first time information of the application server instantiation and the second time information in the above-mentioned embodiment, which will not be repeated here.

[0377] Step 604b, the terminal device sends the information of the first application server to the enabling server. Correspondingly, the enabling server receives the information of the first application server from the terminal device.

[0378] The information of the first application server includes the identification information of the first application server and / or the address information of the first application server.

[0379] The specific implementation of the server deployment method provided by the embodiment of the application will be described below in combination with the application server deployment method shown in FIG. 5 and FIG. 6. For example, the configuration server is an edge configuration server ECS, the enabling server is an edge enabling server EES, the application server is an edge application server EAS, and the terminal device is an edge enabling client EEC.

[0380] As shown in FIG. 7, FIG. 7 is a specific process of deploying an application server provided by an embodiment of the application, which includes:

[0381] Step 701, the EES determines that the EAS needs to be instantiated according to the demand of the EEC, and pre-configures the instantiation time of the EAS.

[0382] For example, the terminal (such as the EEC on the terminal) sends a request message to the EES, and the request message is used to indicate the demand of the EEC. For example, the EEC needs to start an application program, and the application program corresponds to the EAS, so the EAS needs to be instantiated.

[0383] In a possible implementation, the EES configures the instantiation time of the EAS according to the identification of the EAS. It can be understood that the instantiation time corresponding to the identification of different EASs can be the same or different.

[0384] The instantiation time of the EAS can be understood as the time length required for the instantiation of the EAS.

[0385] For example, EAS1 corresponds to an identifier EAS ID#1, and the instantiation time of EAS1 is 10 minutes (min); EAS2 corresponds to an identifier EAS ID#2, and the instantiation time of EAS2 is 30 minutes (min).

[0386] Optionally, the instantiation time of the same EAS can also be different.

[0387] For example, if the key performance indicator (KPI) of EAS1 required by the application A is high, the instantiation time of EAS1 is long. For example, if the KPI is high, the application A requires more resources (such as image processor units and memory processor units), and therefore the instantiation time of EAS1 is long (such as 30 min). If the KPI of EAS1 required by the application A is low, the instantiation time of EAS1 is short. For example, if the KPI is low, the application A requires less resources (such as image processor and memory processor), and therefore the instantiation time of EAS1 is short (such as 15 min).

[0388] In step 702, the edge enabling server sends a request message for triggering EAS instantiation to the first network management system. Correspondingly, the first network management system receives the request message for triggering EAS instantiation from the edge enabling server.

[0389] The request message for triggering EAS instantiation includes the identifier of the EAS that needs to be instantiated. Specifically, the request message for triggering EAS instantiation is used to request instantiation of the edge application server identified by the identifier.

[0390] Optionally, the request message for triggering EAS instantiation can also include resource requirements of the edge application server that needs to be instantiated, such as image processor units and memory processor units corresponding to the edge application server.

[0391] In a possible implementation, the edge enabling server determines that the edge application server needs to be instantiated according to the request of the terminal, and then performs step 702.

[0392] In another possible implementation, the edge enabling server determines that the first edge application server needs to be instantiated based on a triggering condition, and then performs step 702.

[0393] For example, the triggering condition is that the EAS server is overloaded. For example, taking EAS ID#1 as an example, the edge enabling server determines that EAS1 corresponding to EAS ID#1 is overloaded, and then determines that EAS1 needs to be instantiated.

[0394] The first network management system can be an edge computing service provider management node system (ECSP MNS).

[0395] At step 703, the first network management system sends a create EAS request message to the second network management system. Correspondingly, the second network management system receives the create EAS request message from the first network management system.

[0396] The create EAS request message is used to request the creation of the EAS. The create EAS request message carries the identifier of the EAS to be instantiated.

[0397] For example, the first request message can further include the requirements of the EAS to be created, such as the image processor unit and the memory processor unit required by the EAS.

[0398] For example, the second network management system can be an european telecommunications standards institute network functions virtualization management and orchestration (ETSI NFV MANO) responsible for deploying the EAS.

[0399] At step 704, when the second network management system determines that the EAS can be instantiated, the second network management system sends an EAS creation response message to the first network management system. Correspondingly, the first network management system receives the EAS creation response message from the second network management system.

[0400] The EAS creation response message is used to indicate that the EAS instantiation is in progress, or to indicate that the EAS instantiation process is in progress. Optionally, the create EAS response message can further include the identifier of the EAS being instantiated.

[0401] For example, the create EAS response message includes the indication information of instantiation in progress.

[0402] At step 705, the second network management system performs EAS instantiation.

[0403] At step 706, the first network management system sends second indication information to the EES. Correspondingly, the EES receives the second indication information from the first network management system.

[0404] The second indication information is used to indicate that the EAS instantiation is in progress. The second indication information comprises an identifier of the EAS.

[0405] For example, the second indication information can be an EAS instantiation in progress message, which comprises an EAS ID.

[0406] Optionally, the second indication information can also comprise a time length or a time point at which the EAS instantiation is expected to be completed. Alternatively, step 706 can further comprise that the first network management system sends the second indication information and third time information to the edge enabler server. The third time information is used to indicate a time length or a time point at which the edge application server instantiation is expected to be completed.

[0407] At step 707, the EES determines instantiation time information of the EAS corresponding to the identifier of the EAS according to the second indication information.

[0408] The instantiation time information is a remaining time length of the EAS instantiation or a time point at which the EAS instantiation is completed.

[0409] As an example, step 707 can be implemented in the following manner 1 and manner 2:

[0410] Manner 1: In step 706, the first network management system does not provide the third time information to the edge enabler server.

[0411] In a possible implementation manner, step 707 can be implemented in the following manner:

[0412] The edge enabler server can determine a time length or a time point at which the first edge application server instantiation is expected to be completed according to a time point at which the second indication information is received and the time at which the first edge application server instantiation is pre-configured in step 701.

[0413] For example, the edge enabler server pre-configures the time at which the first edge application server instantiation is 30 min, and the time point at which the edge enabler server receives the second indication information from the first network management system is 10:15. Then, the edge enabler server can start timing from the time point at which the second indication information is received, and determine that the remaining time of the first edge application server instantiation is 30 min, or the time point at which the first edge application server instantiation is completed is 10:45.

[0414] Manner 2: In step 706, the first network management system provides the third time information to the edge enabler server.

[0415] In another possible implementation, step 707 can be implemented in the following manner:

[0416] The edge enabling server determines, according to the third time information, a remaining time length of instantiation of the edge application server identified by the first identifier, or a time point at which the instantiation of the edge application server is completed.

[0417] In the case of manner 2, the process of preconfiguring, by the edge enabling server, the time of instantiation of the first edge application server in step 701 can be omitted.

[0418] For example, the third time information includes a time length of 30 min at which the instantiation of the first edge application server is expected to be completed, or a time point of 10:15 at which the instantiation of the first edge application server is expected to be completed, the edge enabling server can directly determine, according to the third time information, that the remaining time of the instantiation of the first edge application server is 30 min, or the time point at which the instantiation of the first edge application server is completed is 10:15.

[0419] Step 708: The edge enabling server sends a registration request message or a registration update request message to the edge configuration server. Correspondingly, the edge configuration server receives the registration request message or the registration update request message from the edge enabling server.

[0420] The registration request message or the registration update request message includes an identifier (EES ID) of the EED, indication information indicating that the instantiation process of the edge application server is being performed, and instantiation time information. The instantiation time information can include a time point at which the instantiation of the edge application server is completed, or a time length at which the instantiation of the EAS is expected to be completed.

[0421] It is worth noting that the above step 708 is an optional step, which can be omitted in actual processes.

[0422] Step 709: The edge configuration server obtains instantiation time information of an edge application server corresponding to each of one or more server identifiers. The instantiation time information of the edge application server corresponding to any server identifier is used to indicate a time point at which the instantiation of the edge application server is completed / the time required for the instantiation of the EAS.

[0423] It is worth noting that, for example, the edge configuration server can obtain, in step 709, the instantiation time information of the edge application server corresponding to any server identifier from step 708.

[0424] As an example, the edge enabler server can proactively send a registration request message or a registration update request message to the edge configuration server so that the edge configuration server can obtain the instantiation time information of the edge application server corresponding to any of the server identities from step 708.

[0425] As another example, the edge configuration server can send a request message to the edge enabler server to request the edge enabler server to send the instantiation time information of the edge application server corresponding to one or more of the server identities. In this way, the edge enabler server can provide the instantiation time information of the edge application server corresponding to one or more of the server identities to the edge configuration server based on the request.

[0426] As another example, the edge configuration server can be pre-configured with the instantiation time information of the edge application server corresponding to one or more of the server identities respectively.

[0427] Step 710, the terminal or the EEC or S-EES of the terminal sends a service provisioning request message to the edge configuration server. Correspondingly, the edge configuration server receives the service provisioning request message from the terminal or the S-EES.

[0428] The service provisioning request message includes a first identity and second time information. The service provisioning request message is used to request to discover a first edge enabler server associated with a first EAS corresponding to the first identity. The first EAS is an EAS used to provide service to the terminal when the terminal is located at a target location.

[0429] The second time information is used to indicate a time (time point) at which the terminal arrives at the target location, or the second time information is used to indicate a time or time point at which the terminal arrives at a service area of the first EAS (EAS service area). It can be understood that the target location can also be understood as the service area of the first EAS (EAS service area).

[0430] For example, the second time information can be a prediction expiration time or an expected expired time. The S-EES is an EES associated with an EAS currently providing service to the terminal at a current location. The following first EES can refer to a target EES, i.e., an EES associated with a first EAS providing service to the terminal after the terminal is located at a target location.

[0431] Step 711, the edge configuration server determines the first edge enabler server according to the state information of the edge application server corresponding to the edge enabler server, the time when the edge application server is instantiated, and the second time information.

[0432] The state information of the edge application server includes the instantiation process, for example, the state of the edge application server can be instantiable but not instantiated, or can be already instantiated.

[0433] The first edge enabler server corresponds to the EES of the EAS that completes instantiation before the time indicated by the second time information.

[0434] For example, if the terminal arrives at location#1 after 5 minutes, for location#1 and EAS ID, the ECS determines that there are two EESs, and the two EESs correspond to two EASs respectively, for EAS#1, a total of 30 minutes is needed to complete instantiation, steps 701-711 are not executed, that is, the instantiation process of the EAS has not been triggered, for EAS#2, a total of 20 minutes is needed to complete instantiation, and the EAS instantiation process has been triggered and executed 15 minutes ago, that is, it still needs 5 minutes to complete EAS instantiation at this moment, assuming that the Prediction expiration time corresponding to the terminal is 5 minutes, then the ECS should prefer the EES#2 corresponding to EAS#2 to provide service for the terminal at this time.

[0435] Step 712, the edge configuration server sends a service provisioning response message. Correspondingly, the terminal / S-EES receives the configuration service response message from the edge configuration server.

[0436] The configuration service response message includes the information of the first edge enabler server, such as the identifier of the first edge enabler server, and / or the address of the first edge enabler server.

[0437] Step 713, the terminal or EEC / S-EES of the terminal sends a discovery request message (EAS discovery request) to the first edge enabler server. Correspondingly, the first edge enabler server receives the discovery request message from the EEC / S-EES.

[0438] The EAS discovery request includes a first identifier (EAS ID) and second time information (prediction expiration time). The EAS discovery request is a first request message for discovering a first application server identified by the first identifier, which is used to provide a service for a terminal when the terminal is located at a target location. The target location can be a specific location or a range of areas, and the embodiments of the present application do not limit this.

[0439] In step 714, the first edge enabler server determines the first edge application server according to the instantiation state information of at least one edge application server associated with the first edge enabler server, the completion time of instantiation of the edge application server, and the second time information.

[0440] The first edge application server is an edge application server that completes instantiation before the terminal reaches the target location at the time indicated by the second time information.

[0441] For example, the terminal reaches location #1 after 5 minutes. Based on location #1 and the first identifier (EAS ID), the first edge enabler server determines that two edge application servers meet the requirements, namely, edge application server 1 (EAS #1) and edge application server 2 (EAS #2). For EAS #1, 30 minutes are required to complete instantiation, and the state is instantiation not started. For EAS #2, 20 minutes are required to complete instantiation, and the state is instantiation triggered to be executed 15 minutes ago. At this time, EAS #1 still needs 30 minutes to complete instantiation, and EAS #2 still needs 5 minutes to complete instantiation. Assuming that the second time information corresponding to the terminal device is 5 minutes, for example, the prediction expiration time is 5 minutes, the first edge enabler server determines that EAS #2 is the target edge application server.

[0442] Optionally, if the first edge application server has not executed instantiation, the method provided by the embodiments of the present application further includes:

[0443] In step 715, the first edge enabler server sends second indication information to the first network management system. Correspondingly, the first network management system receives the second indication information from the first edge enabler server.

[0444] The second indication information is used to trigger the first network management system to perform instantiation of the first edge application server.

[0445] Step 716, the first edge enabler server sends a discovery response (EAS discovery response) message. Correspondingly, the terminal or the S-EES receives the discovery response message from the first edge enabler server.

[0446] The discovery response message includes information of the first edge application server, such as an identifier of the first edge application server, and / or an address of the target edge application server.

[0447] It should be noted that steps 709-715 occur in the application context migration phase, and the target EAS (i.e., the first EAS) and the target EES (i.e., the first EES) need to be discovered, so the EEC can also be replaced by the S-EES, which is the EES to which the terminal is initially connected.

[0448] In the embodiment shown in FIG. 7, in the application context migration phase, when the EES or the EAS is reselected for the terminal, the real-time state of the EAS instantiation can be considered, and at this time, the corresponding EAS / EES can be determined according to the latest time information of the EAS instantiation, so as to avoid selecting an inappropriate EAS, which causes the terminal to be unable to obtain optimal services.

[0449] As shown in FIG. 8, FIG. 8 is an implementation manner of another application server deployment method provided by an embodiment of the present application, and the method comprises the following steps:

[0450] Steps 801-810 are the same as steps 701-710 in the above embodiment, and will not be described here again.

[0451] Optionally, in step 810, the service configuration request message can not carry the second time information, but carries indication information, which is used to indicate the ACR of the service continuity planning type, that is, the discovery of the edge enabler server, the discovery of the application server, and the application context transmission are performed in advance according to the predicted location of the terminal.

[0452] Optionally, in step 810, the service configuration request message does not carry the second time information, and does not carry the indication information. At this time, the configuration server does not need to determine the unique application server.

[0453] Step 811, the configuration server sends a service configuration response message (Service provisioning response). Correspondingly, the EEC / S-EES receives the service configuration response message from the configuration server.

[0454] The service configuration response message comprises one or more enabled servers, one or more server identities associated with each of the enabled servers, instantiation state information of an application server identified by any of the server identities, and a completion time or a predicted completion time of instantiation of the application server identified by any of the server identities.

[0455] It should be noted that the ECS can send all the EES information associated therewith to the EEC or the S-EES, or determine at least one EES according to the EAS ID requested by the terminal / S-EES and the EAS ID corresponding to the EES on the ECS, in which case the ECS also needs to send the EAS ID corresponding to the EES, the instantiation state corresponding to the EAS ID, and the instantiation completion time / length of the EAS to the EEC or the S-EES.

[0456] In step 812, the EEC / S-EES determines the first enabled server according to the second time information of the terminal and one or more server identities associated with each of the enabled servers, instantiation state information of an application server identified by any of the server identities, and a completion time or a predicted completion time of instantiation of the application server identified by any of the server identities.

[0457] The first use server can be the EES corresponding to the EAS that can complete instantiation before the Prediction expiration time.

[0458] In step 813, the EEC / S-EES sends an application server discovery request message (EAS discovery request) to the first enabled server. Correspondingly, the enabled server receives the application server discovery request message from the terminal device.

[0459] The discovery request message comprises an identification of an application server. Optionally, the discovery request message can also comprise second time information or indication information of service continuity planning.

[0460] In step 814, the first enabled server sends an application server discovery response message (EAS discovery response message) to the EEC / S-EES. Correspondingly, the EEC / S-EES receives the application server discovery response message from the first enabled server.

[0461] For example, the first enabled server can directly send the application server discovery response message to the EEC / S-EES, or send the application server discovery response message to the EEC / S-EES through a target enabled server.

[0462] For example, the application server discovery response message includes: information of at least one application server, instantiation in progress of each application server, and an instantiation completion time or an expected instantiation completion time length of each application server. The instantiation in progress is used to indicate whether instantiation is in progress.

[0463] At step 815, the EEC / S-EES determines a first application server from the at least one application server according to the instantiation in progress of each application server, the instantiation completion time or the expected instantiation completion time length of each application server, and the second time information.

[0464] The first application server is an application server that completes instantiation before the terminal reaches the target location.

[0465] Optionally, after step 815, the method provided in the embodiments of the present application can further include:

[0466] At step 816, the EEC / S-EES sends information of the first application server to the first enabling server. Correspondingly, the first enabling server receives the information of the first application server from the EEC.

[0467] For example, the EEC sends an EAS information provisioning procedure message to the first enabling server, and the EAS information provisioning procedure message includes address information of the target application server.

[0468] In the embodiment shown in FIG. 8, when the EEC / S-EES selects an EES or an EAS, the terminal or the S-EES can consider the real-time status of EAS instantiation, and at this time, the corresponding EAS / EES can be determined according to the latest time information of EAS instantiation, so as to avoid selecting an inappropriate EAS, and thus the terminal cannot obtain optimal service.

[0469] As shown in FIG. 9, FIG. 9 is an implementation of a third application server deployment method provided in the embodiments of the present application. The embodiment shown in FIG. 9 is different from the embodiment shown in FIG. 7 in whether the edge configuration server is preconfigured with the instantiation time of the EAS. The specific method includes:

[0470] At step 901, the edge configuration server is preconfigured with the instantiation time of one or more edge application servers.

[0471] Steps 902 to 906 are the same as steps 702 to 706 in the above embodiments, and thus are not described herein again.

[0472] Step 907, the edge enabling server sends second indication information to the edge configuration server. Correspondingly, the edge configuration server receives the second indication information from the edge enabling server.

[0473] The second indication information is used to indicate that the instantiation of the first edge enabling server identified by the EAS ID is being performed.

[0474] For example, the second indication information can be an EAS instantiation in progress message, which includes the EAS ID.

[0475] Step 908, the edge configuration server determines first time information of the instantiation of the first edge enabling server according to the second indication information.

[0476] In a possible implementation, the edge enabling server can determine the time when the instantiation of the first edge enabling server is completed or the remaining time of the instantiation of the first edge enabling server according to the time when the second indication information is received and the time of the instantiation of the first edge enabling server preconfigured by the edge configuration server in step 901.

[0477] The specific implementation manner is described in the foregoing embodiment of step 707, which will not be repeated here.

[0478] Steps 909-914 are the same as steps 710-715 in the foregoing embodiment, which will not be repeated here.

[0479] The ECS can determine the time when the instantiation of the EAS is completed according to the indication information of the EAS instantiation in progress and the time of the instantiation of the EAS. At this time, when selecting the EES or the EAS, the ECS / EES can consider the real-time state of the instantiation of the EAS. At this time, the corresponding EES / EAS can be determined according to the latest time information of the instantiation of the EAS, so as to avoid selecting an inappropriate EAS, thereby causing the UE to be unable to obtain optimal service.

[0480] As shown in FIG. 10, FIG. 10 is an implementation manner of a fourth deployment method of an application server provided in the embodiment of the application. The embodiment shown in FIG. 10 is different from the embodiment shown in FIG. 8 in whether the time of the instantiation of the EAS is preconfigured on the ECS. The specific method comprises the following steps:

[0481] Steps 1001-1009 are the same as steps 901-909 in the foregoing embodiment, which will not be repeated here.

[0482] Steps 1010-1015 are the same as steps 811-816 in the foregoing embodiment, which will not be repeated here.

[0483] The ECS can determine the time / length when the EAS is instantiated completed according to the indication information that the EAS instantiation is in progress and the time of the EAS instantiation, at this time, when the EES or the EAS is selected, the UE can consider the real-time state of the EAS instantiation, at this time, the corresponding EES / EAS can be determined according to the latest time information of the EAS instantiation, and the inappropriate EAS is avoided to be selected, so that the UE cannot obtain the optimal service.

[0484] As shown in FIG. 11, FIG. 11 is a specific implementation manner schematic diagram of the fifth application server deployment method provided by the embodiment of the present application.

[0485] In the embodiment of the present application, the enabling server can correspond to multiple hardware platforms, the application server instantiation time is different on different hardware platforms, and the capabilities of different hardware platforms are also different.

[0486] In a possible embodiment of the present application, the method provided by the embodiment of the present application further includes: the configuration server acquires information of multiple platforms corresponding to at least one enabling server.

[0487] The information of the multiple platforms includes the identification of each platform and / or capability information. The platform is used for deploying the application server, and the capability information of the platform includes the deployment length of the application server on the platform.

[0488] Step 1101, the configuration server and / or the enabling server is configured with time information of application server instantiation corresponding to the identification of at least one platform and / or capability information of at least one platform.

[0489] Step 1102, the first network management system sends a create EES request message (create EES request message) to the second network management system. Correspondingly, the second network management system receives the create EES request message from the first network management system. The create EES request message is used to request to create an enabling server.

[0490] For example, the first network management system is ESCP MNS, and the second network management system is ETSI NFV MANO.

[0491] The create EES request message includes EES requirements, such as EES location, software image, etc.

[0492] Step 1103, the second network management system sends a response message to the first network management system. Correspondingly, the first network management system receives the response message from the second network management system. The response message is used to indicate the instantiation process of the enabling server.

[0493] For example, the response message is a create EES response message, which includes but is not limited to instantiation in progress information.

[0494] Step 1104, the second network management system instantiates the enabling server.

[0495] Step 1105, the second network management system sends a notification message to the first network management system. Correspondingly, the first network management system receives the notification message from the second network management system. The notification message is used to indicate the function of the enabling server.

[0496] For example, the notification message is a create EES notification message, which includes but is not limited to: the function information (EES function) of the enabling server, such as the identification information (EES ID) of the enabling server, the serving location, the address information (EES address) of the enabling server, and the information (list infrastructure ID) of the at least one platform corresponding to the enabling server.

[0497] Step 1106, the enabling server acquires a configuration file.

[0498] In the configuration file (EES profile), the identification information (EES ID) of the enabling server, the port (EES endpoint) of the enabling server, and the information (list infrastructure ID) of the at least one platform corresponding to the enabling server are configured.

[0499] Step 1107, the enabling server sends a registration request message to the configuration server. Correspondingly, the configuration server receives the registration request message from the enabling server.

[0500] For example, the registration request message is an EES registration request message, which includes but is not limited to: the identification information (EES ID) of the enabling server, the identification information (EAS ID) of the application server, the state information (such as EAS instantiated or instantiable) of the application server, and the information (list infrastructure ID) of the at least one platform corresponding to the enabling server.

[0501] Step 1108, the configuration server determines the deployment time of the application server on different platforms according to the information (list infrastructure ID) of the at least one platform corresponding to the enabling server.

[0502] Optionally, the configuration server determines a deployment time of the application server on different platforms according to the information of the at least one platform corresponding to the enabling server (list infrastructure ID) and the configured information.

[0503] At step 1109, the EEC / S-EES sends a service provisioning request message to the configuration server. Correspondingly, the configuration server receives the service provisioning request message from the terminal device.

[0504] For example, the service provisioning request message includes the identification information of the application server (EAS ID) and / or the second time information (expected expired time or prediction expiration time).

[0505] At step 1110, the configuration server determines the first enabling server according to the second time information, the identification information of the at least one platform corresponding to the enabling server, and the capability information of the platform.

[0506] At step 1111, the configuration server sends a service provisioning response message to the EEC / S-EES. Correspondingly, the EEC / S-EES receives the service provisioning response message from the configuration server.

[0507] The service provisioning response message includes the information of the first enabling server, such as the EES address of the first enabling server.

[0508] At step 1112, the EEC / S-EES sends an EAS discovery request message to the first enabling server. Correspondingly, the first enabling server receives the EAS discovery request message from the EEC / S-EES.

[0509] The EAS discovery request message requests to determine the platform to deploy the application server.

[0510] For example, the EAS discovery request message includes but is not limited to the identification information of the application server (EAS ID) and the second time information.

[0511] At step 1113, the first enabling server determines the target platform of the application server identified by the identification information of the application server from one or more first platforms according to the second time information, the identification of the one or more first platforms corresponding to the first enabling server, and the capability information of the one or more first platforms.

[0512] For example,

[0513] Step 1114: The first enabling server sends instruction information to the first network management system. Correspondingly, the first network management system receives the instruction information from the first enabling server. The instruction information is used to indicate the application server identified by the identification information of the application server instantiated on the target platform.

[0514] For example, the instruction information includes, but is not limited to, the identifier of the target platform.

[0515] Step 1115: The first enabling server sends an EAS discovery response message to the EEC / S-EES. Correspondingly, the EEC / S-EES receives the EAS discovery response message from the enabling server.

[0516] The EAS discovery response message includes the application server's address information (EAS address).

[0517] As shown in Figure 12, Figure 12 is a schematic diagram of the specific implementation of the sixth server deployment method provided in the embodiments of this application.

[0518] Steps 1201 to 1203 are the same as steps 1102 to 1104 in the above embodiments, and will not be repeated here.

[0519] Step 1204: The second network management system sends a notification message to the first network management system. Correspondingly, the first network management system receives the notification message from the second network management system.

[0520] The difference from step 1105 in the above embodiment is that the notification message includes: enabling server function information (EES function), such as enabling server identification information (EES ID), serving location, enabling server address information (EES address), and application server deployment duration information on the enabling server.

[0521] Step 1205: Enable the server to obtain the configuration file.

[0522] The difference between step 1106 in the above embodiment is that the configuration file (EES profile) contains the identifier information (EES ID) of the enabling server, the port (EES endpoint) of the enabling server, and the duration of application server deployment on the enabling server.

[0523] Step 1206: The enabling server sends a registration request message to the configuration server. Correspondingly, the configuration server receives the registration request message from the enabling server. The registration request message is used to request the determination of the deployment time of the application server corresponding to the enabling server on the platform.

[0524] Wherein, the difference between step 1107 in the above embodiment is that the registration request message comprises but is not limited to: identification information of the enabling server (EES ID), identification information of the application server (EAS ID), state information of the application server (such as EAS instantiated or instantiable), and time length information of the application server deployment on the enabling server.

[0525] Step 1207 is the same as step 1108 in the above embodiment, which will not be repeated here.

[0526] Step 1208, the configuration server determines at least one enabling server according to the second time information and the time length information of the application server deployment on the enabling server.

[0527] Steps 1209-1210 are the same as steps 1111-1112 in the above embodiment, which will not be repeated here.

[0528] Step 1211, in the case of needing to select an instantiable application server, the enabling server determines the required deployment time of the application server according to the second time information.

[0529] For example, the second time information is prediction expiration time, and the expected time for the terminal device to reach the target location is 10 min, so the required deployment time of the application server needs to be less than 10 min.

[0530] Steps 1212-1213 are the same as steps 1114-1115 in the above embodiment, which will not be repeated here.

[0531] As shown in FIG. 13, FIG. 13 is a specific implementation manner schematic diagram of the seventh server deployment method provided by the embodiment of the application.

[0532] Step 1301, the terminal obtains time information of application server instantiation corresponding to identification of at least one platform, and / or capability information of at least one platform.

[0533] Steps 1302-1307 are the same as steps 1102-1107 in the above embodiment, which will not be repeated here.

[0534] Step 1308, the configuration server sends a service configuration response message to the terminal. Correspondingly, the terminal device receives the service configuration response message from the configuration server.

[0535] The service configuration response message includes, but is not limited to, identification information (EES ID) of the enabling server, a port (EES endpoint) of the enabling server, state information of application server instantiation, and information (list infrastructure ID) of at least one platform corresponding to the enabling server.

[0536] Step 1309, in the absence of an available application server, the terminal device determines a deployment duration of the application server according to identification information of the platform corresponding to the enabling server, and determines the enabling server according to the second time information.

[0537] The application server corresponding to the enabling server is completed instantiation before the terminal device reaches the target location.

[0538] Step 1310, the terminal sends a discovery response message to the enabling server. Correspondingly, the enabling server receives the discovery response message from the terminal device.

[0539] The difference between the step 1112 in the above embodiment and the step 1311 is that the discovery request message includes, in addition to the identification information (EAS ID) of the application server and the second time information, identification information (required infrastructure ID) of the platform corresponding to the application server that needs to be instantiated.

[0540] The steps 1311-1312 are the same as the steps 1114-1115 in the above embodiment, and will not be described here.

[0541] As shown in FIG. 14, FIG. 14 is a specific implementation manner of the eighth server deployment method provided by the embodiment of the application.

[0542] The steps 1401-1407 are the same as the steps 1201-1207 in the above embodiment, and will not be described here.

[0543] Step 1408, the configuration server sends a service configuration request message to the terminal device. Correspondingly, the terminal device receives the service configuration response message from the configuration server.

[0544] The service configuration response message includes, but is not limited to, identification information (EES ID) of the enabling server, a port (EES endpoint) of the enabling server, state information of application server instantiation, and information (list infrastructure ID) of at least one platform corresponding to the enabling server.

[0545] Step 1409, in the absence of an available application server, the terminal device determines the enabling server according to the second time information.

[0546] Step 1410, the terminal device sends a discovery request message to the enabling server. Correspondingly, the enabling server receives the discovery request message from the terminal device.

[0547] The discovery request message includes, but is not limited to, the identification information of the application server (EAS ID), the second time information, and the application server that needs to be instantiated.

[0548] Step 1411, in the case of needing to select the instantiable application server, the enabling server determines the time length of the required deployed application server according to the second time information.

[0549] Steps 1412-1413 are the same as steps 1114-1115 in the above embodiment, and will not be described here.
