Description

Energy-saving resilient network system and method for providing network

technical field

The application relates to the field of communication technology, in particular to an energy-saving flexible network system and network coverage technology.

Background technique

The future network should actively perceive service objects and actively provide cost-effective services, and define standards based on precise services for service objects. Of course, the cornerstone of this standard is not the communication standard, but the smart service standard, and the communication standard is a subset of the smart service standard. Therefore, the solution we are considering now is not only a communication solution, but also a smart service solution, including ICT infrastructure, application service cloud platform, APP application, business operation settlement support, etc. Because different service objects and different services correspond to different contents, the entire environment is time-varying (one person, one network). Service objects and service providers are the starting conditions and driving factors of network time-varying. The environment is An open system in a non-equilibrium state, constantly developing and evolving in the mutual transformation of "disorder" and "order". The difference from the past is that in the intelligent era, terminals are required to have the ability to discover the network and perceive the service environment, and automatically trigger service requests based on the service environment (some service requests are triggered by the network side, and some service requests are triggered by terminal policy) . This automatically triggered APP mechanism should be different from the APP mechanism triggered manually by people in the past. At the same time, the network is also required to have the ability to discover terminals, provide active services for terminals, and related APP applications, but such APPs are loaded on edge nodes or background servers (the more distinctive mode is loaded on edge nodes) . It is necessary to develop an operating system installed on the network side and the edge node side to facilitate the installation of ToB APPs, so that more social forces can develop edge node side and ToB APPs.

1. Network architecture:

It is an energy-saving and elastic network architecture integrating perception-communication-computing in the sixth-generation mobile communication system. From the perspective of the access side, if the future network wants to show its advanced nature, it must be based on environmental cognition, network The four capabilities of on-demand coverage, on-demand coordination of heterogeneous networks, and on-demand terminal access are reflected. Its design goal is to reduce the unpredictability and contingency of the system, and guide the system to evolve towards a predictable and inevitable structure.

The bottom layer is the device layer of the terminal, which includes mobile smart terminals, such as cameras, mobile phones, computers, and a large number of IoT terminals. These terminals have limited capabilities and must be implemented in an edge environment based on an intelligent edge control system. Carry out cooperative networking. If it wants to meet this ability to access the cloud, it must have an intelligent edge control system to realize the access to the cloud on the one hand, and on the other hand to coordinate and organize various heterogeneous terminals in the local environment to complete the requirements of the Internet of Things.

The network layer is between the smart device layer and the upper platform. The function is to enable terminal devices to access the cloud. The premise is to have the ability to access the public network. The network layer is mainly a heterogeneous network composed of 4G and 5G.

The top-level platform can integrate, coordinate and manage heterogeneous networks. Such platforms mainly include network control servers, edge computing servers (MEC), content servers, data centers, business servers, and application servers. Among them, the network control server realizes the management and control of network integration; the edge computing platform mainly completes the perception analysis and processing of data; the content server stores hot content in the CDN; a large amount of data will be generated in the entire network, which will be generated The data center is used for storage; the business server stores the collection of business capability attributes of different Internet of Vehicles and industrial manufacturing; the application server mainly provides the user-oriented human-computer interaction interface interface.

From the perspective of the access side, if the future network is to demonstrate its advanced nature, it must be obtained from the four capabilities of environmental awareness, network on-demand coverage, heterogeneous network on-demand collaboration, and terminal on-demand access. Reflect, and we propose an energy-saving elastic network architecture for future networks.

In order to realize the energy-saving and flexible network architecture, we need to consider five functional levels, including equipment level, business level, network level, application level, and management level. These five levels are the division of the specific performance entities of the energy-saving elastic network architecture.

The first level is the device level. At this level, devices must have the ability to discover resources, where resources include communication, perception, communication, control, computing, storage and other resources. And report this information, as well as the ability to initiate business, execute business, and calculate and process.

The second level is the business level. At this level, service discovery capabilities are required, and service semantic descriptions and resource semantic descriptions can be performed on the cloud, as well as computing processing, business and resource adaptation capabilities.

The third level is the network level. The network layer should include protocol adaptation, access control, networking control, and computing and processing capabilities.

The fourth level is the application level. At this level, it is necessary to realize live broadcast services, asset management, personnel positioning, behavior monitoring, and smart fire protection services.

The fifth level is the management level. This level mainly has the ability to formulate policies and manage security.

2. On-demand network coverage:

First, for the energy-saving elastic network, the system consists of an access network composed of smart terminals, 4G macro coverage network and 5G hotspot coverage network, an edge computing processing platform (MEC), a business control server, a network control server, and a business application server.

The flow of the elastic network on-demand coverage system: the terminal initiates a service request to the service server, the service server analyzes the service type and reports the type to the network control server, and the network control server inquires the location information from the geographic location server and obtains the location feedback from the geographic location server information, the network control server makes a judgment to open the second base station after receiving the location and service information, and sends an instruction to open the micro-station, and the second base station becomes activated after receiving the activation instruction, and sends the For heartbeat information, the network control server analyzes the heartbeat information sent by the base station, stores and updates the information, and returns a heartbeat response to the base station. The base station sends heartbeat information to the network control server every four seconds to maintain the connection. When there is an activated second base station near the terminal before the terminal initiates a service request to the service server, the terminal will directly access the activated second base station.

Figure 5 shows the capability of on-demand coverage—the implementation framework of elastic network on-demand coverage, which is explained as follows:

1) The docking small station adopts UDP protocol to encapsulate the message, and the port is 3345. The base station sends a heartbeat message to the SDN every 5s. This message contains the current status of the base station, and the SDN controller responds to the heartbeat message to ensure a long connection.

2) Create a thread for receiving messages, which is responsible for receiving UDP packets sent by the small base station. First, check whether the frame header elements including ID are legal. If they are not legal, discard them. If they are legal, use different branches to support the business processing of the small base station .

3) Establish a parameter storage table, save all received small base station data, and continuously update this table, so that the current modules can get the latest data.

4) The positioning server and the service identification server send the information to the SDN controller through MQTT communication, and the SDN controller stores the latest location and service information in memory for judgment processing.

5) Every 10s, the SDN controller makes a judgment on the current latest location information. If the current user enters the coverage area of the small base station, the current service is judged. If the user is using a service with high bandwidth requirements, the SDN control server issues an instruction to enable the small base station. If no user satisfies the two conditions at the same time, an instruction to turn off the small base station is issued.

6. After sending an instruction to switch the small base station each time, the SDN controller sends the information of the current user and the base station to the web module for display through MQTT communication.

3. In terms of network intelligent collaboration:

The functional structure of intelligent collaboration is that the 4G base station and the second 5G base station serve as the access point of the server platform. The 4G base station provides network macro coverage, and the terminal equipment is always connected to the 4G base station; when the terminal initiates a high-bandwidth service, the server platform will send an activation command to the 5G base station, and the terminal will select the second base station that is activated nearby to access. The server platform must first have a network control server, whose function is to make decisions based on network conditions; when a terminal initiates a service request, it will report the service situation to the server platform, and the service control server of the server platform will analyze the service type and send The business type is reported to the network management server, and the network control server opens the second base station near the terminal through the location information provided by the geographic location server; if it is necessary to store hot (highly popular) content, there is also data storage on the server platform Server; the network control server sends instructions through the knowledge flow in the knowledge module, and the knowledge module mainly provides knowledge flow service through the information stored by itself. The method of elastic network intelligent collaboration is a method in which the input can be adaptively selected, the output can also be adaptively selected, and the input and output can be matched with each other through the above process.

4. Intelligent identification of network services:

AI-based business intelligent identification: Actively obtain relevant field information of user business data, use AI technology to identify business types, and provide reference for intelligent network processing. Service identification is completed in the service control server, mainly to analyze the service type of the data distributed by the MEC.

Network service identification process: Firstly, the network traffic data is captured through the data platform, and unnecessary fields in the original data are preprocessed to reduce redundancy. Feature selection is performed by selecting part of the data, and finally the traffic is classified through the XGBoost algorithm.
