In order to better describe the technical solution in the embodiments of the present application, the related knowledge is introduced below.

MEC is used for 5G applications and needs to be sunk to the edge of the network to reduce the network delay caused by network transmission. Fig. 1 is a schematic diagram of basic architectures of a 5G network and an MEC in the prior art, as shown in fig. 1, a 5G core network is separated from UP through a CP, UPF can be flexibly deployed at the edge of the network in a sinking manner, and control plane functions such as PCF and SMF can be deployed in a centralized manner. MEC enables operator and third party services to be hosted in the vicinity of access points of user terminals, thereby enabling efficient service delivery by reducing end-to-end delay and load on the transport network.

The MEC system comprises an MEC host layer and an MEC system layer. Wherein, the MEC host layer comprises an MEC platform, an MEC application and a virtualization infrastructure. The virtualization infrastructure can provide computing, storage and network resources for the MEC applications and provide persistent storage and time-related information for the MEC applications, including a data forwarding plane to enforce forwarding rules for data received by the MEC platform and routing of flows between various applications, services and networks. The MEC application is a virtual machine instance running on the MEC virtual infrastructure, in communication with the MEC platform.

The MEC system layer includes an MEC orchestrator. The MEC orchestrator is a core function in the management of the MEC system layer, and is mainly responsible for maintaining an overall view of the MEC system, macroscopically governing the resources and capacity of the MEC network, including all deployed MEC hosts and services, available resources in each host, already instantiated applications, and the topology of the network, etc. When selecting the target MEC host for the user to access, the MEC orchestrator weighs the user requirements and the available resources of each host, and selects the most appropriate MEC host for the user. When the user needs to perform the switching of the MEC host, the MEC orchestrator triggers the switching program.

The 5G core network selects a UPF close to the UE and performs flow control from the UPF to the local data network over the N6 interface. This may be governed based on subscription data of the UE, UE location, information from application functions, policies, or other related traffic.

In view of the characteristics of high setting cost and large network building scale of a single station of a 5G network, a wireless network intelligent control platform is introduced to carry out comprehensive intelligent control and management on an access network, a traditional management mode is innovated, and wireless network resources can be more effectively utilized to reduce the comprehensive cost input of an operator network.

Under the 5G and MEC architectures, high-efficiency guarantee is provided for end-to-end service quality, service experience and the like of mobile users to be solved urgently. This requires overall planning of wireless network resources, management and control in combination with the service requirements of the target user, and consideration of the problems of configuration optimization of the network management of the access network, performance optimization of the RAN network, dynamic measurement optimization of the user, and the like. At present, no complete scheme comprehensively considers the problems, so that the service requirements of the mobile users in the scene cannot be effectively guaranteed.

Fig. 2 is a schematic diagram of a wireless network intelligent control architecture provided in the embodiment of the present application, and as shown in fig. 2, a functional entity of an MEC system is composed of an MEC host layer and an MEC system layer. The MEC system layer includes AN MEC orchestrator and AN AN orchestrator. The MEC system is in the role of AF + DN with respect to the 5G core network, interacting with the 5G core network. The MEC orchestrator is a functional entity of the MEC system layer that may act as an AF to interact with the NEF, or in some cases the MEC orchestrator may interact directly with different network functions of the target 5G network.

For example, the role of the untrusted AF affects the user plane policy through NEF, PCF, SMF, and SMF issues the policy to the UPF through the N4 interface; or the user plane strategy is influenced by directly connecting the PCF and the SMF in the role of the trusted AF, and the SMF issues the strategy to the UPF through the N4 interface.

The MEC system, as a special form of AF, may perform more interactions with the NEF or PCF, and invoke other network openness capabilities of the 5G core network, such as message subscription, QoS, and the like. The 5G core network selects UPF close to the UE and executes UPF to LADN flow control through N6 interface.

And arranging AN AN (access network) orchestrator at AN MEC (centralized management and control) system layer, wherein the AN orchestrator carries out integral orchestration on access network resources according to the current network situation and user requirements, and the integral orchestration comprises non-real-time network management level resource configuration of wireless network equipment, non-real-time network management level resource configuration of wired network equipment, near-real-time tuning configuration of wireless network level and real-time user level QoS (quality of service) strategy control of AN access network.

The AN orchestrator is arranged in the MEC system layer and can perform information interaction with the MEC host layer through a communication interface between the MEC system layer and the MEC host layer. The AN orchestrator may also be separately disposed or disposed in other locations, instead of being disposed in the MEC system layer, which is not limited in this embodiment of the present application.

The AN organizer is used as AN organizer for global resource optimization of the access network and real-time strategy control of a target user, has information interaction interfaces with a network management system, a RAN intelligent control platform and AN MEC host layer, and simultaneously performs information interaction with a 5G core network through AN existing interface Naf. Next, a network management system, an RAN intelligent control platform, and an MEC host layer are introduced.

(1) Network management system

The network management system comprises a wireless network equipment configuration module. A wired network device configuration module may also be included. Wireless network devices such as 5G base stations; wired network devices such as a HINOC device of a wired coaxial network.

Wherein, aiming at the network management level resource allocation, the network management system receives the allocation request from the AN orchestrator. The wireless network equipment configuration module configures the 5G CU and the 5G DU; the wired network device configuration module configures for a HB of the coaxial network.

(2) RAN intelligent control platform

The RAN intelligent control platform comprises a database module, an AI model database module, a third-party application optimization module and an intelligent control middleware. It should be noted that the above module division and naming are only schematic to distinguish the functions of each module.

And the database module receives various data related to the base station from the intelligent control middleware and performs preprocessing and storage on the data. The various types of data are classified into near real-time data and non-real-time data according to real-time performance. Near real-time means that cached data can only be indexed after data segments are generated, and therefore the cached data is near real-time data rather than real-time data.

The non-real-time data is mainly input to the AI model library module for model training, and the near-real-time data is mainly input to the third-party application optimization module for iterative optimization of the optimization algorithm.

And the AI model library module outputs AI models expressed in the forms of functions and the like after acquiring the non-real-time data for preprocessing from the data warehouse module, and the models are used by each application of the third application optimization module according to the requirement to obtain the strategy rule information of each application.

The third-party application optimization module is mainly deployed for various third-party applications for wireless network optimization or management and control based on the AI model, such as load balancing, QoE optimization, RAN slicing, and the like.

The intelligent control middleware is mainly responsible for collecting relevant data of the base station and simultaneously issues the strategy optimization result from the strategy collaborative optimization module to the base station for execution. Alternatively, the intelligent control middleware may be a functional module disposed inside the base station.

Wherein the intelligent control middleware receives a configuration request from the AN orchestrator for a near real-time tuning configuration at a wireless network level. And the intelligent control middleware issues configuration instructions to the 5G CU and the 5G DU, so that near real-time tuning of the wireless network level is realized.

(3) MEC host layer

The MEC host layer is further divided into AN MEC platform, AN MEC application, a UPF and AN AN PCF. The UPF is a gateway device between the base station and the LADN.

The UPF provides communication connection with 5G core networks outside the MEC system through an N4 interface, and the number of the 5G core networks may be 1 or more. The UPF receives the data service of UE terminal user uplink access LADN from the base station side N3 interface, the UPF receives downlink data from the LADN side N6 interface and transfers the downlink data to the base station, and finally the base station transfers the data to the UE through a wireless channel.

The AN PCF receives the strategy control request from the AN orchestrator and issues strategy rules to the 5G CU, so as to realize real-time QoS strategy control of user granularity.

Taking resource allocation as an example, the policy rule refers to how many resources need to be allocated to different third party applications or the resource allocation priority, and the configuration instruction refers to issuing policy information of a user level or a base station level to a user or a base station for execution.

The schematic diagram of the wireless network intelligent control architecture provided by the embodiment of the application provides a basic architecture for information interaction among a wireless network intelligent control platform, an MEC system, a 5G core network, network equipment and UE. The AN orchestrator carries out integral orchestration on access network resources according to the current situation of a network and user requirements, and the AN orchestrator carries out information interaction with a network management system, a RAN intelligent control platform and AN MEC host layer and can only carry out service quality and service experience requirements on target users by carrying out non-real-time network management level resource allocation on wireless network equipment, non-real-time network management level resource allocation on wired network equipment, near-real-time optimization allocation configuration on the wireless network level and real-time user level QoS strategy control on the access network, realizing full-chain intelligent control combining real-time and non-real-time, integral and individual, carrying out intelligent management on the network resources, improving the resource allocation accuracy and improving the user experience.
