In the actual application process, the terminal may request the 5G network to create a protocol data unit (Protocol Data Unit, PUD) session, and the 5G network selects a user plane function according to the location information of the terminal, so as to establish a user plane channel between the terminal and an application instance in the edge data network. However, the terminal can only access an edge application instance in an edge data network through one PDU session, and cannot fully utilize the resources of the edge data network.
Based on this, the embodiment of the application provides a task offloading method, where a terminal application may decompose a task to be executed into a plurality of subtasks, offload the subtasks to edge application instances in different variant data networks in parallel, and accelerate execution of the task. The following detailed description refers to the accompanying drawings.
Referring to fig. 3A, a schematic diagram of a task offloading architecture according to an embodiment of the present application is provided. In the embodiment of the application, a new PDU session type is introduced: multitasking offloads sessions. The terminal establishes a multitasking offload session with the control plane function entity via the access network and indicates which edge data networks the tasks to be performed need to be offloaded to, edge data network 1 and edge data network 2 being shown in fig. 3. Correspondingly, the 5G network allocates corresponding user plane functional entities 1 and 2 for the edge data network 1 and the edge data network 2, and establishes corresponding user plane channels. The end application (application/client deployed on the end) may discover edge application instances deployed in different edge data networks and offload tasks to be performed in parallel onto the edge application instances. The uplink message classifier can offload parallel tasks sent by the terminal to different edge application examples.
Referring to fig. 3B, a schematic diagram of subtask offloading is provided in an embodiment of the present application. As shown in fig. 3, the task is decomposed into 3 sub-tasks on the terminal side, namely sub-task 1, sub-task 2 and sub-task 3. Correspondingly, on the edge side, a corresponding edge application instance is allocated to each subtask for executing the subtask. For example, edge application instance 1 performs subtask 1; edge application instance 2 performs subtask 2; edge application instance 3 performs subtask 3. The following describes the principle thereof in detail.
Referring to fig. 4, a schematic diagram of a registration process is provided in an embodiment of the present application. It can be understood that before the terminal performs the multi-task offloading, it needs to register in the 5G network first to obtain the multi-task offloading capability. Which mainly comprises the following steps.
Step S401: the terminal sends a registration request message to the access management function entity.
It can be understood that the access network, the access management function entity and the unified data management function entity in fig. 4 belong to a communication system, and in this embodiment of the application, the communication system is illustrated by taking a 5G network as an example.
Specifically, the terminal sends a registration request message to the access management functional entity through the access network, and the registration request message may include identification information of the terminal.
Step S402: the access management functional entity obtains the user subscription data from the unified data management functional entity.
After receiving the registration request message sent by the terminal, the access management functional entity exchanges with the unified data management functional entity, obtains user subscription data from the unified data management functional entity, and can judge whether the terminal is allowed to perform multi-task unloading or not through the user subscription data.
Step S403: the access management function entity determines whether to allow the terminal to request a multitasking offload session.
Specifically, the access management functional entity judges whether to allow the terminal to request the multi-task uninstall session according to the user subscription data, and attaches the judgment result to the registration acceptance message to send to the terminal.
Step S404: the access management function entity sends a registration acceptance message to the terminal.
Specifically, the access management functional entity sends a registration acceptance message to the terminal through the access network, wherein the registration acceptance message comprises multi-task unloading capability indication information, and the task unloading capability indication information is used for representing that the multi-task unloading capability is supported or not supported.
It can be understood that if the terminal has completed the subscription of the capability of unloading multitasking, the unified data management function entity has user subscription data of the terminal, and the access management function entity determines that the terminal is allowed to request the session of unloading multitasking according to the user subscription data, and accordingly, the indication information of the capability of unloading multitasking is used for representing supporting the capability of unloading multitasking. Further, the terminal may perform a service request for multitasking offloading.
It should be noted that in some possible embodiments, it may be possible to directly default to the terminal supporting the multi-tasking offload capability, so that the terminal does not need to initiate a registration procedure before performing the service request for multi-tasking offload. That is, the service request of the multitasking offload is directly performed without performing the steps shown in fig. 4, which should be within the scope of the present application.
Referring to fig. 5, a flow chart of a task unloading method is provided in an embodiment of the present application. The method can be applied to the architecture shown in fig. 1 and 2, and as shown in fig. 5, mainly comprises the following steps.
Step S501: the terminal transmits a service provision request message to the edge configuration server.
As described above, the edge-enabled server registers with the edge configuration server, and thus the edge configuration server can provide information of the edge-enabled server to clients on the terminal.
Before the terminal performs task offloading, firstly, a service providing request message is sent to the edge configuration server, wherein the service providing request message is used for indicating the edge configuration server to feed back information of a corresponding edge enabling server.
Specifically, the service providing request message includes a terminal identifier and a terminal application identifier, and it can be understood that the terminal application identifier is an identifier corresponding to a client of the terminal. In an alternative embodiment, the service providing request message may further include security credentials, terminal location information, terminal application client type, etc.
Step S502: the edge configuration server transmits a service providing response message to the terminal.
And after receiving the service providing request message, the edge configuration server sends a service providing response message to the terminal. The service providing response message comprises an edge enabling server list, wherein the edge enabling server list comprises an edge enabling server address and an edge data network identifier corresponding to the edge enabling server, and the edge data network identifier is used for identifying the position of an edge data network.
Specifically, the edge configuration server may screen out an edge enabling server meeting the requirement of a preset screening rule according to one or more of the terminal identifier, the terminal position information, the terminal application type and the terminal application identifier, and send the screened edge enabling server list to the terminal. Specifically, the screening rules are not limited in particular, and those skilled in the art may adjust the screening rules accordingly according to actual needs.
Step S503: the terminal interacts with the control plane functional entity to establish a multitasking offload session.
Specifically, the terminal may determine whether the 5G network allows it to create a session of a multitasking offload type according to the task offload capability indication information in the embodiment shown in fig. 4. If the task unloading capability indication information indicates that the terminal supports the multi-task unloading capability, the terminal application decomposes the task to be executed into N subtasks according to the requirement, selects N edge enabling servers corresponding to the N subtasks from an edge enabling server list, and determines edge data network identifiers corresponding to the N edge enabling servers. Where N > 1, for example, n=2, n=5, etc., the specific numerical values thereof are not limited in the embodiments of the present application.
The terminal interacts with the control plane functional entity through the access network to establish a multitasking offload session. In the process of establishing the multi-task unloading session, the terminal sends the edge data network identifiers corresponding to the N edge enabling servers to the control plane functional entity.
Step S504: the control plane functional entity interacts with the uplink message classifier to create a user plane tunnel between the uplink message classifier and the access network.
Specifically, the control plane functional entity selects an uplink message classifier and creates a user plane tunnel between the uplink message classifier and the access network. The uplink message classifier is used for splitting uplink messages.
Step S505: the control plane functional entity interacts with the user plane functional entity k to create a user plane tunnel between the uplink message classifier and the user plane functional entity k.
It can be understood that each edge data network has its corresponding control plane function entity, and after the control plane function entity obtains the edge data network identifier in step S503, a user plane tunnel between the uplink packet classifier and the user plane function entity can be created according to the edge data network identifier.
It should be noted that, in the embodiment of the present application, the user plane functional entity establishes N user plane tunnels with N user plane functional entities corresponding to the N edge enabled servers, respectively. For example, n=3. Correspondingly, the user plane functional entity and the user plane functional entity 1 corresponding to the edge enabling server 1 establish a user plane tunnel 1; the user plane functional entity establishes a user plane tunnel 2 with the user plane functional entity 2 corresponding to the edge enabling server 2; the user plane function entity establishes a user plane tunnel 3 with the user plane function entity 3 corresponding to the edge enabling server 3.
For simplicity of description, in the embodiment of the present application, the user plane functional entity k is taken as an example to describe. It is understood that the user plane function k may be any one of the N user plane functions. Step S506: the control plane functional entity interacts with the uplink message classifier to set the splitting rule.
Specifically, the offloading rule includes correspondence between N user plane tunnels, N user plane functional entities, and the N edge enabling servers. For example, the offload rule indicates that a message to be sent to the edge-enabled server k or the edge application instance k is sent to the user plane function entity k through the user plane tunnel k. The edge application instance k is an edge application instance deployed in the edge enabling server k.
Step S507: the terminal sends an application discovery request message to the edge enabled server k.
Specifically, the terminal sends an application discovery request message to an uplink message classifier through a user plane tunnel between the uplink message classifier and the access network, the uplink message classifier sends the application discovery request message to a user plane functional entity k through a user plane tunnel k according to a distribution rule, and the user plane functional entity k routes the application discovery request message to an edge enabling server k. It may be appreciated that in the embodiment of the present application, the terminal needs to send N application discovery request messages to the N edge-enabled servers through the N user plane tunnels, where each application discovery request message corresponds to one edge-enabled server.
Step S508: the edge-enabled server k sends an application discovery reply message to the terminal.
Specifically, the edge enabling server k sends an application discovery response message to the user plane functional entity k, the user plane functional entity k sends the application discovery response message to the uplink message classifier through the user plane tunnel k, and the uplink message classifier sends the application discovery response message to the terminal through the user plane tunnel between the uplink message classifier and the access network. The application discovery response message contains address information of the edge application instance.
It may be understood that in the embodiment of the present application, the terminal needs to receive N application discovery response messages sent by the N edge enabled servers, where each application discovery response message includes address information of an edge application instance. Thus, the terminal obtains address information of N edge application instances. Step S509: the terminal sends subtask information to the edge application instance k.
Specifically, the terminal sends sub-task information to the uplink message classifier through a user plane tunnel between the uplink message classifier and the access network according to the address information of the edge application example k, the uplink message classifier sends the kth sub-task information to the user plane functional entity k through the user plane tunnel k according to the distribution rule, and the user plane functional entity k routes the kth sub-task information to the edge application example k.
