Description
Technical Field
[0001] The present invention relates to a method and system for transmitting electric power data based on 5G slicing, and belongs to the field of mobile communications. Background Art
[0002] According to the overall plan for the safety protection of the power secondary system, the power system business can be divided into the production control area business and the management information area business. Among them, the production control area business is currently mainly carried by the SDH transmission network with TDM as the core, and the management information area business is currently mainly carried by the data network with TCP / IP as the core. The production control area business and the management information area business are carried by devices with different cores to achieve physical isolation.
[0003] With the upgrade of key power grid business systems and bandwidth upgrades such as the new generation of safety control, protection, automation, and information management regional services, the existing traditional power communication network based solely on TDM or TCP / IP cannot meet the needs of various businesses, resulting in different businesses requiring different equipment to carry them separately, resulting in low transmission efficiency, easy data loss, increased costs for power grid business development, and a large waste of power fiber core resources. Summary of the invention
[0004] The purpose of the present invention is to provide a power data transmission method and system based on 5G slicing, so as to solve the problems of low data transmission efficiency, high error rate and poor security caused by the use of existing technologies for data transmission.
[0005] To achieve the above objectives, the technical solutions and corresponding solutions provided by the present invention have the following beneficial effects:
[0006] A power data transmission method based on 5G slicing of the present invention comprises the following steps:
[0007] 1) Review the UE's contracted slice information. After the review is passed, the UE obtains the configuration information of each slice, which includes the service type carried by each slice;
[0008] 2) The UE acquires and parses the service data of the power device, and allocates the service data to the corresponding slice according to the service type to which the service data belongs, so that each slice transmits the service data according to the allocated address.
[0009] The beneficial effects of the above scheme are as follows: the present invention adopts 5G slicing for data transmission. Specifically, when parsing and transmitting power data, the server needs to first review the UE contracted slice information. After the review is passed, the address of the slice corresponding to the UE will be sent down. The UE parses and transmits the power data through the address of the corresponding slice. To a certain extent, the security of system transmission data is guaranteed, and the efficiency and correctness of data transmission are improved.
[0010] As a further improvement of the method, it is also necessary to monitor the operating status of the slices. For abnormal slices, adjust the service types carried by the remaining slices and switch the service data allocated to the abnormal slice to the remaining slices for transmission.
[0011] The beneficial effects of the above scheme are as follows: for the process of slicing power data, the system uses the server to interact with the UE and the core network periodically to monitor the operating status of the slices, and can switch abnormal slices in time so that data can continue to be transmitted, thereby improving the reliability of system operation.
[0012] As a further improvement of the method, the UE uses 4 slices for dialing, namely slice 0, slice 1, slice 2 and slice 3; slice 0 is used for authentication-free communication with the authentication server, slice 1 is used to carry remote control services, slice 2 is used to carry remote adjustment and remote signaling services, and slice 3 is used to carry telemetry services.
[0013] The beneficial effect of the above scheme is: the present invention divides the slices in the UE into 4, among which different service data are transmitted through different slices, so that the system operation division of labor is clear and the data transmission efficiency is improved.
[0014] As a further improvement of the method, the process of reviewing the UE subscription slice information includes:
[0015] 1) The slice management server registers the IMEI in the UE module that can use the slice and the IMSI number of the contracted SIM card information;
[0016] 2) The UE first performs authentication-free dial-up communication with the authentication server through the 0-way slice;
[0017] 3) The UE dials slice 1, slice 2, and slice 3. The core network performs a contract review on the IMSI in the received UE dialing signaling, and sends the IMEI of the UE and the IMSI of the SIM card that have passed the review to the slice management server for further review by the authentication server. At the same time, the UE generates a machine code based on the IMEI and IMSI number, generates a registration code based on the confidentiality algorithm, and sends the machine code and registration code to the slice management server using the 0-way default network;
[0018] 4) The authentication server compares the IMEI and IMSI numbers sent by the core network with the machine code sent by the UE to ensure that the machine code is not counterfeited by the UE; at the same time, for the machine code that has passed the review, the registration code is checked according to the decryption algorithm to verify the correctness of the registration code.
[0019] The beneficial effects of the above scheme are as follows: the contracted UE and SIM card information are registered in the slice management server, providing a basis for retrieval for subsequent authentication. After that, the UE dials and uploads the corresponding IMEI and IMSI to the core network. The core network verifies the IMSI in the UE dialing signaling and then uploads the UE's IMSI+IMEI to the slice authentication server. Since these two numbers are mentioned in the signaling, the security is relatively high. At the same time, the UE synchronously generates a random code based on the IMEI and IMSI and uploads it to the authentication server. The authentication server compares the UE information uploaded by the core network and the UE with the IMEI and IMSI corresponding to the contracted UE in the slice management server to see if they are correct. The UE body and the SIM card are verified through the above multiple methods to prevent unregistered UEs from accessing the slice, which ensures the security of the system to a certain extent.
[0020] As a further improvement of the method, the way to assign addresses to each slice is: after the UE obtains the configuration information of each slice, it fills the configuration information into the PDP context of its corresponding CID, and restarts dialing of slice 1, slice 2, and slice 3.
[0021] The beneficial effect of the above solution is that the address allocated to each slice provides a basis for subsequent data transmission.
[0022] A power data transmission system based on 5G slicing of the present invention includes a core network, a 3A server and a UE, wherein the core network and the 3A server are used to review the UE's contracted slice information; the UE is used to obtain the configuration information of each slice after the review is passed, and parse the business data of the power device, wherein the configuration information stores the business type carried by each slice; the business data is allocated to the corresponding slice according to the business type to which the business data belongs, so that each slice transmits the business data according to the allocated address.
[0023] The beneficial effects of the above scheme are as follows: the present invention adopts 5G slicing for data transmission. Specifically, when parsing and transmitting power data, the server needs to first review the UE contracted slice information. After the review is passed, the address of the slice corresponding to the UE will be sent down. The UE parses and transmits the power data through the address of the corresponding slice. To a certain extent, the security of system transmission data is guaranteed, and the efficiency and correctness of data transmission are improved.
[0024] As a further improvement of the method, the server periodically interacts with the UE and the core network to monitor the operating status of the slices, and for abnormal slices, adjusts the service types carried by the remaining slices and switches the service data allocated to the abnormal slice to the remaining slices for transmission.
[0025] The beneficial effects of the above scheme are as follows: for the process of slicing power data transmission, the system uses the server to interact with the UE and the core network periodically to monitor the operation status of the slice, and can switch the abnormal slice in time so that the data can continue to be transmitted, thereby improving the reliability of the system operation. As a further improvement of the method, different slices in the UE are used to carry different types of services, and the slices include: slice 0, slice 1, slice 2 and slice 3. Slice 0 is used to communicate with the authentication server without authentication, slice 1 is used to carry remote control services, slice 2 is used to carry remote adjustment and remote signaling services, and slice 3 is used to carry telemetry services.
[0026] The beneficial effect of the above scheme is: the present invention divides the slices in the UE into 4, among which different service data are transmitted through different slices, so that the system operation division of labor is clear and the data transmission efficiency is improved.
[0027] As a further improvement of the method, the process of the core network and the 3A server reviewing the UE subscription slice information includes:
[0028] 1) The slice management server registers the IMEI in the UE module that can use the slice and the IMSI number of the contracted SIM card information;
[0029] 2) The UE first performs authentication-free dial-up communication with the authentication server through the 0-way slice;
[0030] 3) The UE dials slice 1, slice 2, and slice 3. The core network performs a contract review on the IMSI in the received UE dialing signaling, and sends the IMEI of the UE and the IMSI of the SIM card that have passed the review to the slice management server for further review by the authentication server. At the same time, the UE generates a machine code based on the IMEI and IMSI number, generates a registration code based on the confidentiality algorithm, and sends the machine code and registration code to the slice management server using the 0-way default network;
[0031] 4) The authentication server compares the IMEI and IMSI numbers sent by the core network with the machine code sent by the UE to ensure that the machine code is not counterfeited by the UE; at the same time, for the machine code that has passed the review, the registration code is checked according to the decryption algorithm to verify the correctness of the registration code.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0041] Example of a power data transmission system based on 5G slicing:
[0042] The present invention applies 5G slicing technology to power data transmission, and using 5G slicing for power data transmission has the characteristics of high security, high speed and high efficiency.
[0043] Figure 1 This is a schematic diagram of the power service slice transmission involved in this embodiment. The data transmission is mainly realized by mutual communication between the 3A+ slice management server with slice management capability (referred to as: slice management server), the core network with slice capability, the UE with multi-channel dialing capability, and the power service terminal. Among them, the UE contains 4 slices, namely slice 0, slice 1, slice 2, and slice 3. Slice 0 is used for authentication-free communication with the authentication server and will not carry communication services; slice 1 is used to transmit remote control service data, slice 2 is used to transmit remote adjustment and telemetry service data, and slice 3 is used to transmit telemetry service data.
[0044] Based on the above-mentioned 5G slicing-based power data transmission system, a 5G slicing-based power data transmission method of the present invention can be implemented. The purpose of the method is: after the power service terminal sends the service data of the power device to the UE, the UE parses and transmits the received power data through slicing.
[0045] The specific implementation process of the method is as follows: the slice management server reviews the contracted slice information of the UE. Only after the review is qualified will the slice management server send the configuration letter of the corresponding slice to the UE. After the UE obtains the slice configuration information, it fills the configuration information into the PDP context of the CID corresponding to its dialing and performs slice dialing. After the core network and the authentication server verify that the context information is correct, the IP corresponding to the slice is allocated to the UE. The UE parses the service data of the connected power device according to the allocated IP and transmits the corresponding slice data. During the slice transmission, the authentication server communicates with the core network and the UE periodically, periodically judges the operating status of each slice, and flexibly adjusts the service bearing properties of the corresponding slice.
[0046] Specifically, combined Figure 2-Figure 5 It can be seen that the steps of power data transmission through slices are:
[0047] Step 1: The slice management server registers the UE that can use the slice and the SIM card information that has been signed. That is, the customer enters the corresponding IEMI number of the UE module to be deployed and the IMSI number of the SIM card used by the UE into the database to provide a basis for subsequent authentication and retrieval.
[0048] Step 2: The UE dials the 0th route to communicate with the authentication server. (This route is free of configuration and does not require authentication by the authentication server. This route will not carry other business communications.)
[0049] Step 3: The UE performs dialing on the 1st, 2nd and 3rd routes. After the core network receives the slice dialing signaling, it verifies whether the IMSI number in the UE dialing signaling is the SIMI card that has signed up. If so, the UE's IMEI number and the IMSI number of the SIM card are sent to the slice management server for further review by the authentication server.
[0050] Step 4: At the same time, the UE generates a machine code based on the IMEI+IMS number, and then generates a registration code based on the confidentiality algorithm. It uses the 0-way default network and sends the machine code and registration code to the slice management server according to the private protocol.
[0051] Step 5: The authentication server compares the IMEI+IMSI number sent by the core network and the machine code sent by the UE with the machine code registered in the database to ensure that the machine code is not counterfeited by the UE. After the authentication server verifies that the machine code is a registered machine code, it verifies the registration code according to the decryption algorithm to check whether the registration code is correct.
[0052] Step 6: The slice management server sends the slice information to the UE. The slice information includes the information in Table 1. After obtaining the information, the UE defines the information to the PDP context of the corresponding dialed CID, and then restarts the dialing process of slices 1, 2, and 3. After that, the core network and the authentication server verify that the context information is correct and assign the corresponding address to the verified slice.
[0053] Step 7: The UE obtains the IP corresponding to each slice, and then starts to parse the service data, analyzes the data frames such as telesignaling, remote control, remote adjustment, and telemetry, and allocates the parsed data to the corresponding air interface IP for data transmission according to the provisions of the following table.
[0054] slice Slice Name Slice Username Slice password Importance level Bearer Services 1 ApnName1 UserName1 PassWord1 A remote control 2 ApnName2 UserName2 PassWord2 B remote control, remote signaling 3 ApnName3 UserName3 PassWord3 C telemetry
[0055] Step 8: When the slice management server obtains a certain slice communication anomaly through the core network or UE, it adjusts the slice service bearer and sends the slice configuration to the UE again. (For example, if the slice 1 communication anomaly is detected, the UE is notified that the first slice is abnormal, and the second slice is used to carry the remote control, and the remote adjustment and remote credit are transmitted to slice 3)
[0056] The present invention proposes a specific method for using 5G slices for power data transmission. It does not focus on the specific operation method of the core network slice, but invents how to use the slice on the UE side. In actual use, the authentication server is deployed on the client side, and the client has a certain degree of independent development capabilities for the server, so this patent uses this feature to deploy a system in the authentication service to provide better scalability and manageability for the management of the contracted slices, while facilitating operators to manage and maintain the 5G network. At the same time, the present invention verifies the UE body and SIM card to prevent unregistered UEs from accessing the slices, which ensures the security of the system to a certain extent.
[0057] Embodiment of the power data transmission method based on 5G slicing:
[0058] This embodiment proposes a method for power data transmission based on 5G slicing, which does not focus on the specific operation method of the core network slice, but on how to use the slice on the UE side and how to solve the problem when the slice has abnormal transmission. The specific power data transmission method has been described in detail in the embodiment of the power data transmission system based on 5G slicing, and will not be repeated in this embodiment.
