Description

Technical Field

[0001] This invention belongs to the field of communication network technology, and in particular relates to a communication management method for power communication networks based on network slicing. Background Technology

[0002] Network slicing refers to the creation of multiple isolated virtual logical subnets with different characteristics on demand, based on a shared physical infrastructure and a unified open network architecture, through deep decoupling and flexible reconstruction of network functions. Due to its security, reliability and stability, it has been widely used in the construction of power communication networks.

[0003] Specifically, in invention patents CN202011481778.0 "Network Slicing and Path Selection Optimization Method and System for Power Internet of Things" and CN202011197033.1 "A Bandwidth Resource Allocation Method for Power Communication Network Based on 5G Slicing," network slicing and bandwidth resource optimization improve the efficiency of communication data processing while ensuring communication reliability. However, the following technical problems exist: The number of power IoT devices requiring communication data management and the amount of communication data from different power IoT devices vary to some extent in different power distribution areas. Therefore, the bandwidth resource utilization rate varies to some extent in different power distribution areas. If it is not possible to determine whether network slicing is necessary based on the bandwidth resource utilization of different power distribution areas, the complexity of network management of the communication network will be high.

[0004] To address the aforementioned technical problems, this invention provides a communication management method for power communication networks based on network slicing. Summary of the Invention

[0005] To achieve the objectives of this invention, the following technical solution is adopted: According to one aspect of the present invention, a communication management method for power communication networks based on network slicing is provided.

[0006] A communication management method for power communication networks based on network slicing, characterized in that it specifically includes: S1 divides the power distribution area by the location of the communication base station, and determines whether the power distribution area needs to be divided into network slices based on the network bandwidth occupancy data of the communication base station in the power distribution area. If yes, proceed to step S4; otherwise, proceed to the next step. S2 acquires the electrical equipment corresponding to different power IoT devices in the power distribution area and uses them as matching electrical equipment. Based on the type of matching electrical equipment and the transmission records of historical fault data, the communication reliability requirements of different power IoT devices and the type of power IoT devices are determined. S3, based on the communication reliability requirements of different power IoT devices in the power distribution area and the type of power IoT devices, determines that the power distribution area needs to be divided into network slices, and then proceeds to the next step; S4 divides the network slices of different power IoT devices according to the type of power IoT devices in the power distribution area, and allocates network bandwidth to different power IoT devices in different network slices according to the communication reliability requirements of the power IoT devices in different network slices, and determines the allocated network bandwidth of the network slices.

[0007] The beneficial effects of this invention are as follows: 1. Based on the network bandwidth occupancy data of the communication base stations in the power distribution area, it is determined whether the power distribution area needs to be divided into network slices. This enables the screening of power distribution areas with high network bandwidth occupancy, ensuring the reliability of network communication in power distribution areas with high occupancy, and reducing the technical problems of communication management difficulties caused by unnecessary division of network slices in power distribution areas.

[0008] 2. Based on the different communication reliability requirements and types of power IoT devices in different power distribution areas, it is determined whether a power distribution area needs to be divided into network slices. This not only fully considers the different needs of different power distribution areas for network slice division due to differences in communication reliability requirements, but also comprehensively considers the number and types of power IoT devices in the power distribution area to screen power distribution areas with higher reliability requirements, and also lays the foundation for differentiated network slice division.

[0009] 3. Based on the communication reliability requirements of power IoT devices in different network slices, the allocation of network bandwidth for power IoT devices in different network slices is determined, and the allocation of network bandwidth for the network slices is determined. On the basis of ensuring that the network bandwidth required for higher communication reliability requirements is higher, by comprehensively considering the power IoT devices in different network slices, more network bandwidth can be allocated to the network slices with more power IoT devices and higher reliability requirements.

[0010] A further technical solution involves dividing power distribution areas based on the location of communication base stations, specifically including: The location of the communication base station determines the power IoT devices managed by the communication base station, and power IoT devices using the same communication base station are assigned to the same power distribution area.

[0011] A further technical solution is that the network bandwidth occupancy data of the communication base station includes the amount and rate of network bandwidth occupancy at different times, the time period when the occupancy rate is greater than the preset occupancy rate, and the duration percentage.

[0012] A further technical solution is that the communication reliability requirement of the power Internet of Things (IoT) device is in the range of 0 to 1, wherein the higher the communication reliability requirement of the power IoT device, the higher the reliability level requirement of the communication of the power IoT device.

[0013] A further technical solution is that the type of the power IoT device is determined according to the communication reliability requirements of the power IoT device. Specifically, the reliability requirement range corresponding to the power IoT device is determined according to the communication reliability requirements of the power IoT device, and the type of the power IoT device is determined according to the preset type matched by the reliability requirement range.

[0021] Example 1 To solve the above problems, according to one aspect of the present invention, such as Figure 1 As shown, according to one aspect of the present invention, a communication management method for power communication networks based on network slicing is provided, characterized in that it specifically includes: S1 divides the power distribution area by the location of the communication base station, and determines whether the power distribution area needs to be divided into network slices based on the network bandwidth occupancy data of the communication base station in the power distribution area. If yes, proceed to step S4; otherwise, proceed to the next step. It should be noted that the division of power distribution areas based on the location of communication base stations specifically includes: The location of the communication base station determines the power IoT devices managed by the communication base station, and power IoT devices using the same communication base station are assigned to the same power distribution area.

[0022] It is understood that the network bandwidth usage data of the communication base station includes the amount and rate of network bandwidth usage at different times, the time period when the usage rate is greater than the preset usage rate, and the duration percentage.

[0023] In one possible embodiment, step S1 above, determining whether the power distribution area needs to be divided into network slices based on the network bandwidth occupancy data of the communication base stations in the power distribution area, specifically includes: The network bandwidth occupancy rate of the communication base stations in the power distribution area is determined at different times using the occupancy data. The comprehensive bandwidth occupancy rate of different power distribution areas is determined by combining the proportion of time on different dates when the occupancy rate is greater than the preset occupancy rate. The comprehensive bandwidth occupancy rate is used to determine whether the power distribution area needs to be divided into network slices.

[0024] Furthermore, determining whether the power distribution area needs to be divided into network slices based on the overall bandwidth utilization rate specifically includes: When the overall bandwidth occupancy rate of the power distribution area is greater than the set occupancy rate threshold, it is determined that the power distribution area needs to be divided into network slices. When the overall bandwidth occupancy rate of the power distribution area is not greater than the set occupancy rate threshold, it is determined that the power distribution area does not need to be divided into network slices.

[0025] In another possible embodiment, the step S1 above, determining whether the power distribution area needs to be divided into network slices based on the network bandwidth occupancy data of the communication base stations in the power distribution area, specifically includes: S11 uses the occupancy data to determine the network bandwidth occupancy rate of the communication base stations in the power distribution area at different times, and determines whether there is a time when the occupancy rate is greater than the preset occupancy rate. If so, proceed to the next step; otherwise, determine that the power distribution area does not need to be divided into network slices. S12 determines the average occupancy rate of the communication base station by measuring the network bandwidth occupancy rate of the communication base station at different times, and determines whether the average occupancy rate of the communication base station is within the preset occupancy rate range. If yes, proceed to the next step; otherwise, proceed to step S14. S13 takes the moment when the occupancy rate is greater than the preset occupancy rate as the screening moment. The occupancy rate assessment of the screening moment is determined by the number of screening moments within the preset duration, the network bandwidth occupancy rate of different screening moments, and the cumulative duration ratio of screening moments in the preset market. It is then determined whether the occupancy rate assessment of the screening moment of the communication base station meets the requirements. If yes, proceed to the next step. If no, it is determined that the power distribution area does not need to be divided into network slices. S14 obtains the average duration of the time period when the occupancy rate of the communication base station is greater than the preset occupancy rate, and determines the comprehensive bandwidth occupancy rate of the communication base station by combining the occupancy rate assessment, average occupancy rate and average network bandwidth occupancy at the screening time of the communication base station. The comprehensive bandwidth occupancy rate is used to determine whether the power distribution area needs to be divided into network slices.

[0026] In another possible embodiment, the step S1 above, determining whether the power distribution area needs to be divided into network slices based on the network bandwidth occupancy data of the communication base stations in the power distribution area, specifically includes: S11 uses the occupancy data to determine the network bandwidth occupancy rate of the communication base stations in the power distribution area at different times, and determines whether there is a time when the occupancy rate is greater than the preset occupancy rate. If so, proceed to the next step; otherwise, determine that the power distribution area does not need to be divided into network slices. S12 determines the average occupancy rate of the communication base station by measuring the network bandwidth occupancy rate of the communication base station at different times, and determines whether the average occupancy rate of the communication base station is greater than the maximum preset occupancy rate. If so, it is determined that the power distribution area needs to be divided into network slices; otherwise, proceed to the next step. S13 takes the moment when the occupancy rate is greater than the preset occupancy rate as the filtering moment, and determines whether the cumulative duration of the filtering moments in the preset market is greater than the preset duration percentage. If yes, proceed to the next step; otherwise, proceed to step S15. S14 determines the occupancy rate assessment of the screening time by the number of screening times within a preset time period, the network bandwidth occupancy rate of different screening times, and the cumulative time percentage of screening times in the preset market. It then determines whether the occupancy rate assessment of the screening time of the communication base station meets the requirements. If yes, proceed to the next step; otherwise, determine that the power distribution area does not need to be divided into network slices. S15 obtains the average duration of the time period when the occupancy rate of the communication base station is greater than the preset occupancy rate, and determines the comprehensive bandwidth occupancy rate of the communication base station by combining the occupancy rate assessment, average occupancy rate and average network bandwidth occupancy at the screening time of the communication base station.

When the basic reliability requirements are greater than a preset threshold, the communication reliability requirements of the power Internet of Things equipment are determined based on the basic reliability requirements of the power Internet of Things equipment. When the basic reliability requirement is not greater than a preset threshold, the historical fault types and the number of historical faults of different historical fault types of the matching electrical equipment within a preset time period are determined by the historical fault data of the matching electrical equipment. It is then determined whether the number of historical faults of the matching electrical equipment within the preset time period is less than the preset number of faults. If so, the communication reliability requirement of the power Internet of Things equipment is determined by the basic reliability requirement of the power Internet of Things equipment. If not, proceed to the next step. The fault compensation amount required for the reliability of the electrical IoT device is determined by the historical fault types of the matched electrical equipment within a preset time, the number of historical faults for different historical fault types, and the amount of communication data for different numbers of historical faults. The communication reliability requirements of the power IoT device are determined based on the fault compensation amount according to the reliability requirements of the electrical IoT device and the basic reliability requirements.

Based on the communication reliability requirements of different power IoT devices in the power distribution area, the average value of the communication reliability requirements of the power IoT devices in the power distribution area is determined. It is then determined whether the average value of the communication reliability requirements of the power IoT devices in the power distribution area meets the requirements. If yes, it is determined that the power distribution area does not need to be divided into network slices. If not, proceed to the next step. The comprehensive communication reliability requirements for different types of power IoT devices are determined by considering the number of different types of power IoT devices and their communication reliability requirements. Based on the comprehensive communication reliability requirements of different types of power Internet of Things (IoT) devices, the regional reliability requirements of the power distribution area are determined, and based on the regional reliability requirements, it is determined whether the power distribution area needs to be divided into network slices.

[0034] S4 divides the network slices of different power IoT devices according to the type of power IoT devices in the power distribution area, and allocates network bandwidth to different power IoT devices in different network slices according to the communication reliability requirements of the power IoT devices in different network slices, and determines the allocated network bandwidth of the network slices.

[0035] Specifically, the method for determining the allocated network bandwidth for the network slice is as follows: The allocation of network bandwidth for different power IoT devices is determined based on their communication reliability requirements and communication data types. Furthermore, the allocation of network bandwidth for different network slices is determined based on the number of power IoT devices in each network slice and the allocated network bandwidth.

[0036] In one possible embodiment, the method for determining the allocated network bandwidth for the network slice in step S4 above is as follows: S41 determines the allocated network bandwidth for different power IoT devices based on their communication reliability requirements and communication data types, and determines the baseline allocated network bandwidth for different network slices based on the number of power IoT devices in different network slices and the allocated network bandwidth. S42 determines whether the number of IoT devices in the network slice is within a preset range. If yes, proceed to the next step; otherwise, proceed to step S44. S43 determines the slice communication reliability requirements of different network slices based on the number of IoT devices in different network slices and the communication reliability requirements of different IoT devices. It then determines whether the slice communication reliability requirements of the network slices are met. If yes, the baseline allocated network bandwidth is used as the allocated network bandwidth of the network slice. If no, proceed to the next step.
