[0069] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0070] Under the 5G architecture, MEC servers are deployed in computer rooms at prefecture-level cities and lower locations, bringing data services closer to the user side and reducing interaction delays. Figure 1 As shown by the thick solid line, the data service initiated by the UE (User Equipment) passes through the gNode B (base station), the UPF (User Plane Function) in the base station room / district room, and is connected to the MEC server 1. At the same time, the MEC server can also reach the MEC server 2 after passing through the city-level UPF. This deployment method will sacrifice some latency, but it is still faster than reaching the Internet after passing through the core network.

[0071] With the explosive growth of XR (extended reality) and cloud gaming services, traffic on the edge will increase significantly. How to manage and control various services and traffic on the edge so that users who sign different service levels can have different SLA experiences (bandwidth, latency, reliability, etc.) requires further research and solutions.

[0072] Edge computing is achieved by sinking the UPF of the user plane, so that the business can be diverted to the edge side and edge services can be provided. However, the currently sunk UPF only provides routing and diversion at the network level, is unaware of the business usage, and cannot perform fine control on the business SLA on the edge side.

[0073] like Figure 2 As shown in the 5G network system architecture diagram:

[0074] UPF network element: User Plane Function (UPF) is a functional network element of the user plane of the terminal device UE. Its main functions include packet routing and forwarding, billing, local paging triggering and other services; edge business applications provide services for edge business applications through the edge ECP platform.

[0075] SMF network element: Session Management Function (SMF), which is mainly responsible for all control plane functions of terminal device session management, including UPF entity selection, Internet Protocol (IP) address allocation, session Quality of Service (QoS) attribute management, and obtaining policy control and charging (PCC) rules from the Policy Control Function (PCF) entity.

[0076] The UPF entity is connected to the SMF entity through the N4 interface. As the anchor point of the Protocol Data Unit (PDU) session connection, the UPF entity is responsible for data packet filtering, data transmission or forwarding, rate control, and generation of billing information for terminal devices.

[0077] ECP: Edge service platform, a platform that accesses the mobile edge network and provides business services. It can be an operator's own platform (such as Migu) or provided by a third-party service provider (such as Tencent, iQiyi, etc.).

[0078] like Figure 3 As shown, under the existing technology, UPF selects the corresponding ECP service according to the target IP address in the user application (APP), and executes the Internet Best Efforts QoS strategy in a multi-service and high-traffic scenario. It is unable to monitor the real-time service type and content according to the user's specific contracted service, and thus cannot provide corresponding SLA service guarantees.

[0079] The embodiment of the present invention provides a service control method and device, which supports the identification of user service types at the network edge side, and executes service policies according to service contract information, realizes service scheduling and quality control of user service SLA, and solves the problem that the service SLA cannot be finely controlled at the network edge side.

[0080] The embodiment of the present invention provides a service control method, which is executed by a user plane function entity UPF, such as Figure 4 As shown, the method includes:

[0081] Step 101: Receive a user service request sent by a session management function entity SMF, where the request carries edge computing service ECP subscription information;

[0082] Step 102: Execute the corresponding service level agreement SLA policy according to the ECP contract information of the service, and establish a communication link between the user and the ECP corresponding to the service.

[0083] In this embodiment, UPF stores the mapping relationship between ECP contract information and SLA policy. After receiving the user's service request, UPF executes the corresponding SLA policy according to the ECP contract information of the service, establishes a communication link between the user and the ECP corresponding to the service, and thus performs fine-grained control over the SLA of the edge-side service.

[0084] In some embodiments, before receiving a user service request sent by the SMF, the method further includes:

[0085] Receive the ECP contract information and SLA policy sent by the SMF, where the ECP contract information includes the contracted services and their corresponding SLA levels;

[0086] A mapping relationship between the ECP contract information and the SLA policy is established and stored.

[0087] In some embodiments, after establishing a communication link between the user and the ECP corresponding to the service, the method further includes:

[0088] Performing business identification detection according to the business information;

[0089] Notify the ECP of the information of the real-time services that are identified as not being in conformity with the contracted services;

[0090] Execute the violation handling process.

[0091] In some embodiments, the service information includes at least one of the following: real-time link quality, ECP credibility, and user APP credibility.

[0092] In some embodiments, the execution violation handling process includes any of the following:

[0093] Lowering the quality of service (Qos) of the communication link of the real-time service;

[0094] Lowering the SLA level of the communication link of the real-time service;

[0095] The communication link of the real-time service is cut off.

[0096] This embodiment proposes a mechanism for executing business policies based on business service contract information, such as Figure 6 As shown in the figure, UPF executes the corresponding policies of ECP contract services (such as high priority scheduling, QoS guarantee, bandwidth priority, and selection of low-latency routes) according to the ECP (edge ​​computing service) information in the user's APP (which can be IP address, contract content, SLA level, etc.), and provides users and ECP with corresponding SLA service guarantees. ECP can propose the requirements of signing different SLA services to operators and use the corresponding business services.

[0097] The embodiment of the present invention also provides a service control method, which is executed by a session management function entity SMF, such as Figure 5 As shown, the method includes:

[0098] Step 201: receiving a service request of a user reported by an authentication management function entity AMF, wherein the service request carries the location of the user;

[0099] Step 202: Send the service request to the corresponding user plane function entity UPF according to the user's subscription information.

[0100] In some embodiments, before receiving the user service request reported by the AMF, the method further includes:

[0101] Receive ECP contract information from the edge computing service management system ECM, where the ECP contract information includes the contracted service and its corresponding SLA level;

[0102] The ECP contract information and SLA policy are sent to the UPF.

[0103] In a specific embodiment, the ECP and user service policy configuration process is as follows: Figure 7 As shown, first, the edge computing service provider submits the contract information to the operator's ECM (edge ​​computing business management system), including: 1) contracted business services, such as high-definition video, cloud games, remote monitoring, IoT services, etc.; 2) SLA service levels corresponding to the contracted business services, such as latency, bandwidth, reliability and other service guarantees for premium, exclusive, premium, gold, silver, standard and other customers; then, ECM synchronizes the contract information to SMF, and SMF sends the policy to the corresponding UPF based on the contract information, and UPF configures and maps the business contract information with the SLA policy.

[0104] In another specific embodiment, the UPF service policy execution process is as follows: Figure 8 As shown, the user UE initiates a service request (such as e-sports cloud games, high-definition video live broadcast, etc.), AMF reports the user location to SMF, SMF sends the service request to UPF according to the user's contract information (enters the designated location to perform UPF diversion), UPF executes the SLA policy according to the user and ECP contract information (such as e-sports cloud game ECP signed an exclusive gold medal SLA service, then selects the corresponding QoS priority guarantee link for routing and scheduling), and establishes a service channel with the ECP corresponding to the user and service.

[0105] In another specific embodiment, the UPF service real-time identification and processing process is as follows: Fig. 9As shown in the figure, after the user UE initiates a service request, the UPF executes the SLA policy according to the contracted service reported by the user APP. In order to prevent the service reported by the user APP from being inconsistent with the actual running service (such as running a large number of high-bandwidth and high-traffic services such as high-definition videos on the link of the contracted cloud game), the UPF can run the real-time service identification and detection function based on algorithms such as link real-time quality, ECP credibility, user APP credibility, and risk assessment models. If the detected and identified service is inconsistent with the contracted service, the service violation handling process will be executed (such as lowering the link Qos, SLA level or disconnecting the link, etc.).

[0106] like Fig.10 As shown, in order to implement the solution proposed in this embodiment, UPF needs to have service control capabilities, in which four functions are added:

[0107] (1) Business parsing and identification: Ability to parse business layer data, such as Hyper Text Transfer Protocol (HTTP) and Real-time Transport Protocol (RTP), to achieve business perception;

[0108] (2) Business contract management: Provide management of user contract information and ECP contract information to ensure the consistency between contract information and measured information;

[0109] (3) Service SLA management: Implement SLA rule management, match links with different QoS or SLA levels according to contract information, service type, and service content, and implement SLA guarantees;

[0110] (4) Service scheduling control: Based on contract information, SLA rules and real-time link status, it implements functions such as routing control for services with different priorities, link QoS guarantee, and alarm monitoring.

[0111] This embodiment implements SLA control of 5G edge services, making up for the lack of manageable and controllable edge services in the 5G environment; among them, UPF adds service perception attributes, implements service identification and monitoring, and realizes service SLA guarantee through service contracting. It solves the problem of controlling and implementing complex business needs when the 5G user plane UPF is sunk in the future. According to the different sinking locations of the user plane UPF in this embodiment, campus-level and field-level edge services emerge in an endless stream, and personalized business needs will increase day by day. By increasing the service attribute capabilities of UPF, various edge needs can be better responded to; by upgrading the general UPF to an enhanced UPF, the core network elements can be transformed without system, and various edge needs can be met by lightweight transformation of UPF.

[0112] The embodiment of the present invention also provides a service control device, which is executed by a user plane function entity UPF, such as Fig.11 As shown, the device comprises:

[0113] The receiving module 21 is used to receive a user service request sent by the session management function entity SMF, where the request carries the edge computing service ECP subscription information;

[0115] In this embodiment, UPF stores the mapping relationship between ECP contract information and SLA policy. After receiving the user's service request, UPF executes the corresponding SLA policy according to the ECP contract information of the service, establishes a communication link between the user and the ECP corresponding to the service, and thus performs fine-grained control over the SLA of the edge-side service.
