Technical Field
The present invention relates to the field of communications, and in particular, to a reliable access method, apparatus, and storage medium for an edge internet of things proxy entity.
Background
Edge computing is a computing model that moves data collection, computation, and storage to the edge of a network, i.e., a device or terminal. The mode can rapidly process data, reduce the network bandwidth requirement and improve the response speed and privacy protection. In smart grids, the application of edge computation is very widespread.
Firstly, the edge calculation can perform real-time data analysis and processing on the terminal equipment, so that the real-time monitoring and optimization of the power grid are realized. For example, in an electrical power system, edge calculations may help monitor the operating state of electrical equipment, predict maintenance requirements, and thereby improve the stability and reliability of the power supply.
Second, edge computation may enable autonomous control and optimization of the device. By implementing the intelligent algorithm on the terminal equipment, the interaction between the equipment can be more intelligent, thereby realizing the self-adaption and optimization of the power grid. For example, in a smart meter, edge calculations may help monitor the user's power usage behavior, thereby achieving accurate billing and energy conservation.
In addition, the edge calculation can also realize privacy protection and safe transmission of data. In smart grids, privacy protection of data is an important issue. Through edge calculation, the data can be processed and analyzed locally, so that the privacy of the user is protected. Meanwhile, the edge calculation can also ensure the safety and the integrity of the data through encryption and a safe transmission technology.
Applying edge computation in smart grids can bring many advantages. First, edge computation may eliminate physical gaps between grids. In different power grid areas, sharing and interaction of data can be achieved through edge calculation, so that overall operation of a power grid is more coordinated and stable.
Secondly, edge computation can improve the stability and reliability of the grid. Through real-time data monitoring and analysis, problems in the power grid can be found in time, so that quick early warning and handling are realized.

the communication quality of at least two connections is measured from the second data.
After the edge internet of things proxy entity receives first data sent by a terminal connected with the edge internet of things proxy entity, because of the bandwidth limitation of a communication network, the communication network is blocked due to the fact that the data volume of original data sent by a plurality of terminals is too large, whether the first data meets preset requirements is judged first, the preset requirements can be format requirements, data size requirements, data content requirements and the like, and when the first data meets the preset requirements, namely the edge internet of things proxy entity only needs to forward the first data to the communication network, the edge internet of things proxy measures the communication quality of at least two connections according to the first data; when the first data does not meet the preset requirement, that is, the edge internet of things proxy entity only needs to process the first data into second data meeting the preset requirement and then send the second data to the communication network, the process of processing the first data into the second data meeting the preset requirement is also an edge calculation process, and after calculation is completed, the edge internet of things proxy measures the communication quality of at least two types of connection according to the second data.
Alternatively, the first data and the second data may be structured data or unstructured data. When the first data is unstructured data, such as when the first data is monitoring video data, the first data is subjected to resolution compression and downsampling, the first data is compressed to obtain second data while the first data characteristics are reserved, and after the first data is compressed, the pressure of a communication network is relieved, and the stability of the communication network is improved.

determining a first target device of the first data on the communication network according to the first data;
determining an access mode supported by first target equipment according to the first target equipment;

The first data includes information of the first target device, and the edge internet of things proxy entity determines an access mode supported by the first target device according to the information of the first target device, and optionally, the edge internet of things proxy entity may determine the access mode supported by the first target device according to the access mode recorded in the information of the first target device, or may determine the access mode supported by the first target device by using different connections to communicate with the first target device. And after determining the access mode supported by the first target equipment according to the information of the first target equipment, the edge internet of things proxy entity selects at least two types of connection according to the access mode supported by the first target equipment and measures the communication quality of the at least two types of connection. Since the second data is processed by the first data, the first data includes all information of the corresponding second data.
The first target device may be a last level server of the edge proxy entity, a last level edge device or other device with computing power at a last level, or may be a master station of the edge proxy entity.
Optionally, the at least two access manners are access manners used by the first target device expected edge internet of things proxy entity.
And the edge internet of things proxy entity selects at least two types of connection according to the access mode supported by the first target equipment and according to the feedback expectation of the first target equipment, and measures the communication quality of the at least two types of connection.
Specifically, the first target device feeds back the expected connection mode according to various access modes supported by the first target device and the bandwidth occupancy rate of the various access modes;
optionally, the first target device may further feed back the expected connection mode according to the real-time requirement of the data sent by the edge internet of things proxy entity, such as the data size, when the data size is larger, select a connection mode with higher bandwidth, and when the data size is smaller, select a connection mode with lower bandwidth;
optionally, the first target device may also feed back the expected connection mode according to the model of the edge internet of things proxy entity or the distance between the first target device and the edge internet of things proxy entity, for example, when the distance between the first target device and the edge internet of things proxy entity is relatively close, RS485 wired connection is used, and when the distance between the first target device and the edge internet of things proxy entity is relatively far, 5G or 4G connection is used.
Specifically, the edge internet of things proxy entity sends a first message to the first target device, wherein the first message is used for indicating a plurality of access modes supported by the edge internet of things proxy entity, and the plurality of access modes are different access modes of a cross-network mode;
the edge internet of things proxy entity receives a second message returned by the first target device, wherein the second message is used for indicating at least two access modes, and the at least two access modes are also access modes supported by the edge internet of things proxy entity.
According to the access mode supported by the first target device, parameters such as bandwidth occupation conditions of the current access mode are selected to generate a second message by two communication modes meeting the first data or second data transmission requirements, and the second message is sent to an edge internet of things proxy entity, for example, when the first data has higher real-time requirements or the first data is unstructured data with larger data volume, 5G access, 4G access or RS485 interface access with higher transmission efficiency can be selected, and when the second data is data with lower real-time requirements, loRa access or NB-IoT access can be selected.
Optionally, in the process that the edge internet of things proxy entity establishes at least two kinds of connection with the communication network through at least two kinds of access modes, if the at least two kinds of access modes comprise a 5G access mode, the edge internet of things proxy entity derives a non-access stratum NAS key between the edge internet of things proxy entity and an access and mobility management network element in the communication network under the condition that the main authentication passes; the edge internet of things proxy entity sends NAS keys to the application functions, wherein the access and mobility management network elements and the application functions are configured to be capable of using the NAS keys for safe communication, namely multiplexing the NAS keys deduced by the edge internet of things proxy entity to ensure the communication safety of the access and mobility management network elements and the application functions.
S303, the edge thing allies oneself with proxy entity and chooses the connection with the best communication quality in at least two kinds of connections, the proxy terminal obtains the service from the communication network.
For example, the edge-proxy entity measures at least one of the following for each of at least two connections with the first target device: packet loss rate, or data transmission rate, wherein the connection with the best communication quality is the connection with the smallest data transmission rate (meaning that there can be a relatively large data transmission capacity, or the connection is relatively idle) in the connection with the packet loss rate below the threshold.
The terminals include at least one of low-side terminals, medium-side terminals, distribution terminals, and power transformation terminals.
Terminals physically connected to the edge internet of things proxy may be located on the low-voltage side, the medium-voltage side, and the distribution and transformation system of the power grid, for example, the low-voltage side terminals may be: phase change switches, bay low voltage regulators, etc.; the medium-voltage side terminal may be: the internet of things type load monitor, wave recording fault indicator, temperature sensor and the like, and the power distribution terminal and the power transformation terminal can be: the system comprises an Internet of things type high-precision leakage circuit breaker, a low-voltage distribution monitoring terminal, an electric energy quality adjusting device and the like. The terminals in all subsystems of the power system are connected into the Internet of things, so that the power system is better monitored, the data processing capacity of the intelligent power grid can be optimized, and the whole operation of the power grid is more coordinated and stable.
In summary, since the edge internet of things proxy entity can establish at least two connections with the communication network, the edge internet of things proxy entity can select the connection with the best communication quality for the accessed terminal, and the proxy terminal obtains the service from the communication network, so that the stability and reliability of the service are ensured, and the service experience of the terminal is ensured.
