[0002] Smart meter reading technology is a new type of metering management approach that replaces traditional manual meter reading through automation, digitization, and networking. Its core approach is to automatically transmit data to a cloud platform through intelligent terminals (such as smart power terminals), enabling efficient and accurate usage monitoring, fee settlement, and abnormality alerts. It also allows users to query energy consumption in real time, optimize resource utilization, and help municipalities improve management efficiency and reduce labor costs. It is a critical infrastructure for smart cities and the digital transformation of energy.

[0003] The existing smart meter reading system data transmission methods are divided into the following two methods: Option 1: transforming the power terminal into a card-inserted integrated terminal to complete cell access by receiving the 4G / 5G signal from the macro station; Option 2: amplifying the macro station signal through a signal repeater and transmitting it to the power terminal in the basement.

[0004] However, the above-mentioned smart meter reading technology has the following disadvantages: 1) It does not take into account that when the power terminal is in a basement or remote mountainous area, the macro station signal coverage is weak or basically non-existent, and cannot support the access and data transmission of the power terminal; because there are situations where the macro station users are close to saturation and the number of power terminals is large; 2) It may not be able to meet the business data transmission needs of all power terminals, and the macro station does not consider the difference between power terminals and ordinary users, and cannot guarantee the stable transmission of power terminal data. Summary of the Invention

[0005] In order to solve the above technical problems existing in the prior art, the present invention provides a resource scheduling optimization method, device and storage medium for an intelligent power distribution terminal.

[0006] The technical method of the embodiment of the present invention is implemented as follows:

[0012] Calculating, by the base station, a target scheduling priority of the UE based on the QoS parameter configuration and channel quality;

[0014] When it is determined that the target scheduling priority is lower than that of the other power terminals, the UE is allowed to establish a PDU session and perform resource allocation.

[0015] In some embodiments, the method further includes: when the number of users in the current cell reaches the preset maximum number of activated users in the cell, directly rejecting the access request of the current user.

[0016] In some embodiments, the method also includes: when it is determined that the target scheduling priority is higher than the other power terminals, releasing the data resource block, triggering the PDU session modification process, and lowering the target scheduling priority; after determining that the modified scheduling priority is lower than the other power terminals, allowing the UE to establish a PDU session and perform resource allocation.

[0017] In some embodiments, the base station calculates the target scheduling priority of the UE based on the QoS parameter configuration and the channel quality, including: calculating the target scheduling priority of the UE according to the channel quality of the UE, the QoS priority in the QoS parameter configuration, and the obtained historical throughput and the remaining penalty factor, wherein the calculation formula of the target scheduling priority is as follows:

[0018]

[0019] Among them, QoS priority is the priority parameter corresponding to 5QI; the remaining delay penalty factor is the remaining time of the delay budget. The smaller the remaining time, the higher the score.

[0020] In a second aspect, an embodiment of the present invention provides an electronic device, comprising: a memory for storing executable instructions; and a processor for implementing the above-mentioned resource scheduling optimization method for the intelligent power distribution terminal when executing the executable instructions stored in the memory.

[0021] In a third aspect, an embodiment of the present invention provides a computer-readable storage medium storing executable instructions for causing a processor to execute the executable instructions to implement the above-mentioned resource scheduling optimization method for the intelligent power distribution terminal.

[0022] The resource scheduling optimization method for the intelligent distribution terminal provided in the embodiment of the present invention first responds to the access request initiated by the UE to obtain the current number of online users in the cell; determines whether the current number of online users has reached the preset maximum number of activated users in the cell; when it is determined that it has not reached the maximum number, further determines whether the UE is a power terminal; when it is determined that the UE is a power terminal, the UE reports a PDU session establishment request to the core network, the core network performs authentication and service parameter determination, and sends a PDU session establishment command to the base station; the base station calculates the target scheduling priority of the UE based on the QoS parameter configuration and channel quality; the base station determines whether the target scheduling priority is lower than that of other power terminals; when it is determined that the target scheduling priority is lower than that of other power terminals, the UE is allowed to establish a PDU session and perform resource allocation. In this way, on the one hand, the present invention ensures that the business data of the power terminal can be uploaded and received normally and stably, and can also provide business services to other mobile phone users; on the other hand, the use of wireless backhaul base stations to realize the function of smart meter reading improves the signal environment of power terminals in areas with poor signal coverage such as basements and remote mountainous areas, compared with the existing method of simply inserting cards into power terminals, and increases the online rate of power terminals; at the same time, it also solves the problem that macro stations with nearly saturated number of power terminal access users cannot guarantee stable transmission of business data.

[0031] See also Figure 1 , Figure 1 Schematic diagram of the structure of a smart power distribution terminal data wireless backhaul system 10 provided in an embodiment of the present invention. This embodiment of the present invention provides a smart power distribution terminal data wireless backhaul system, which includes at least a base station, a receiving unit, a coverage unit, an electric meter (i.e., another electric power terminal in the present invention), a common user (i.e., a UE in the present invention), and a core network for establishing communications.

[0032] Figure 1In the system used in this solution, the public network base station is an outdoor macro station, and the receiving unit is a CPE module. A SIM card is inserted into the module and connected to the outdoor macro station as a terminal. Its function is to forward data between the coverage unit and the macro station and establish a data transmission channel between the coverage unit and the outdoor macro station.

[0033] The coverage unit and the receiving unit are connected by an optoelectronic composite cable. The coverage unit is an integrated 4G / 5G dual-mode full-network base station. By establishing a cell, it is responsible for the access and data services of power terminals and other ordinary mobile phone users.

[0034] The base station in the embodiment of the present invention can support access by both power terminals and ordinary mobile phone users.

[0035] The embodiment of the present invention provides a resource scheduling optimization method for an intelligent power distribution terminal, which is applied to a wireless data backhaul system for an intelligent power distribution terminal. Figure 2 , Figure 2 This is a flow chart of the resource scheduling optimization method for the intelligent power distribution terminal provided by the embodiment of the present invention, which will be combined with Figure 2 The steps shown are explained.

[0036] Step S210: The base station obtains the number of current online users in the cell in response to the access request initiated by the UE.

[0037] In some embodiments, a UE (User Equipment) initiates an access request as its initial attempt to connect to a cell base station to obtain services. When a user turns on a mobile phone, tablet, or other device, or when the device moves from an unavailable area to a covered area, or when the user launches a specific network application, the UE sends an access request signal to the base station. In some embodiments, the access request includes various information, such as the UE's identity (used by the network to authenticate the user), the type of service requested (e.g., voice calls, data access, video streaming, power communications), and the communication capabilities supported by the UE (e.g., whether it supports 5G and supported frequency bands).

[0038] In some embodiments, the number of currently online users in a cell refers to the number of user devices (UEs) within the coverage area of a specific cell at a given moment that have successfully connected and remain connected. As the core management device for the cell, the base station is responsible for monitoring and counting this number in real time. The base station exchanges signaling with connected UEs, tracking their connection status and thus accurately obtaining the number of online users.

[0039] Step S220: Determine whether the number of current online users reaches the preset maximum number of activated users in the cell.

[0040] In some embodiments, the preset maximum number of activated users in a cell refers to the maximum number of online user devices that can be supported simultaneously, which is determined based on factors such as the performance of the cell's base station equipment, available wireless spectrum resources, signal processing capabilities, and service quality standards considered during network planning. It is a preset fixed parameter.

[0041] For example, after evaluation and planning, a cell's base station equipment and network resources are determined to be capable of providing network connectivity for 100 user devices while maintaining a certain quality of service. Therefore, the preset maximum number of active users for this cell is 100. When the number of currently online users in the cell approaches or reaches this preset value, the network may face resource constraints, requiring appropriate measures such as restricting new user access, adjusting resource allocation strategies, or expanding network capacity to ensure network stability and service quality.

[0042] Step S230: When it is determined that the requirement is not met, further determining whether the UE is a power terminal.

[0043] In some embodiments, power terminals refer to various types of user equipment used in the power system field, such as smart meters, power monitoring terminals, distribution automation terminals, etc. These devices undertake important tasks such as power data collection, transmission and control.

[0044] In some embodiments, the base station primarily determines whether the UE is a power terminal based on information such as the device identifier, service type identifier, or specific identification code carried in the UE's access request signaling. For example, when accessing the network, the power terminal will carry a unique device type identifier in the request message according to specific protocol rules. The base station can determine the type of UE by parsing this identification information. In addition, the judgment can be supplemented by the type of service the UE requests access. If the requested service is related to the power system (such as a power data collection service), the possibility of the UE being a power terminal is further increased.

[0045] In step S240, when it is determined that the UE is the power terminal, the UE reports a PDU session establishment request to the core network, the core network performs authentication and service parameter determination, and sends a PDU session establishment command to the base station; the base station checks the QoS parameter configuration in the command.

[0046] In some embodiments, a PDU (Protocol Data Unit) is a protocol data unit. After receiving the request, the core network authenticates the UE to verify its identity and authorization to access the network and use the requested service. Furthermore, based on the UE's request and network policies and resources, the core network determines the appropriate service parameters, including QoS parameters, for the PDU session.

[0047] In some embodiments, QoS parameters may include ARP, packet loss rate, maximum bit rate, etc.

[0048] Step S250: The base station calculates the target scheduling priority of the UE based on the QoS parameter configuration and channel quality.

[0049] In some embodiments, the target scheduling priority is a priority identifier assigned to the UE based on factors such as the service type of the UE, the quality of service requirement, and the current load status of the cell.

[0050] Step S260: The base station determines whether the target scheduling priority is lower than that of other power terminals.

[0051] In this invention, a base station, a key device in a wireless communication network connecting UEs and the core network, is responsible for managing the allocation and scheduling of radio resources within a specific area (cell). The target scheduling priority of the UE (user equipment) is determined by the network based on factors such as the UE's service type, quality of service (QoS) requirements, and user subscription information. This priority is used to measure the relative importance of the UE in resource scheduling. The UE's target scheduling priority is also compared with the scheduling priorities of other power terminals.

[0052] Step S270: When it is determined that the target scheduling priority is lower than that of the other power terminals, the UE is allowed to establish a PDU session and perform resource allocation.

[0053] The resource scheduling optimization method for the intelligent distribution terminal provided in the embodiment of the present invention first responds to the access request initiated by the UE to obtain the current number of online users in the cell; determines whether the current number of online users has reached the preset maximum number of activated users in the cell; when it is determined that it has not reached the maximum number, further determines whether the UE is a power terminal; when it is determined that the UE is a power terminal, the UE reports a PDU session establishment request to the core network, the core network performs authentication and service parameter determination, and sends a PDU session establishment command to the base station; the base station calculates the target scheduling priority of the UE based on the QoS parameter configuration and channel quality; the base station determines whether the target scheduling priority is lower than that of other power terminals; when it is determined that the target scheduling priority is lower than that of other power terminals, the UE is allowed to establish a PDU session and perform resource allocation. In this way, on the one hand, the present invention ensures that the business data of the power terminal can be uploaded and received normally and stably, and can also provide business services to other mobile phone users; on the other hand, the use of wireless backhaul base stations to realize the function of smart meter reading improves the signal environment of power terminals in areas with poor signal coverage such as basements and remote mountainous areas, compared with the existing method of simply inserting cards into power terminals, and increases the online rate of power terminals; at the same time, it also solves the problem that macro stations with nearly saturated number of power terminal access users cannot guarantee stable transmission of business data.

[0054] In some embodiments, the method further includes: when the number of users in the current cell reaches the preset maximum number of activated users in the cell, directly rejecting the access request of the current user.

[0055] In some embodiments, the method also includes: when it is determined that the target scheduling priority is higher than the other power terminals, releasing the data resource block, triggering the PDU session modification process, and lowering the target scheduling priority; after determining that the modified scheduling priority is lower than the other power terminals, allowing the UE to establish a PDU session and perform resource allocation.

[0056] In some embodiments, the base station calculates the target scheduling priority of the UE based on the QoS parameter configuration and the channel quality, including: calculating the target scheduling priority of the UE according to the channel quality of the UE, the QoS priority in the QoS parameter configuration, and the obtained historical throughput and the remaining penalty factor, wherein the calculation formula of the target scheduling priority is as follows:

[0057]

[0058] Among them, QoS priority is the priority parameter corresponding to 5QI; the remaining delay penalty factor is the remaining time of the delay budget. The smaller the remaining time, the higher the score.

[0059] The following describes an exemplary application of an embodiment of the present invention in a practical application scenario.

[0060] The use of wireless backhaul by the base station indicates that the backhaul rate is limited, that is, the air interface resources of the cell are limited. When there are other ordinary mobile phone users accessing the cell and there are many power terminals connected to the base station, the access and uplink and downlink services of ordinary terminals may have an impact on the ongoing services of the power terminals, affecting the service stability of the power terminals. At the same time, the base station must ensure that all power terminals can stably access the cell and perform service data transmission. Therefore, this embodiment proposes a special resource scheduling method for power terminals and other mobile phone terminals in the cell, which can be seen in Figure 3 include:

[0061] Limit access priority: within the cell's capacity, if the number of online power terminal users has reached the maximum number of activated users in the cell, no new mobile terminal will be allowed to access; in the case of simultaneous access, power terminal users will be given priority.

[0062] Limit service priority: When the UE reports a PDU session establishment request to the core network, the core network authenticates the request and determines the service parameters, and sends a PDU session establishment command to the base station. The base station checks the QoS parameter configuration (ARP, packet loss rate, maximum bit rate, etc.) in the command, and comprehensively calculates its scheduling priority based on the physical resource occupancy of the current cell. If it is higher than other power terminals, its scheduling priority is appropriately lowered to be lower than other power terminals to ensure normal upload of power terminal data. At the same time, it is considered that the current channel conditions do not meet the needs of the service. The actual QoS parameters of the UE at this time are used as the QoS configuration that the base station can meet, and are reported to the core network through the N2 message, triggering the PDU session modification process.

[0063] The present invention proposes a method for differentially scheduling physical resources of power terminal users and ordinary terminals, thereby improving the stability of power terminal data transmission.

[0064] The present invention applies wireless backhaul base stations to intelligent meter reading technology, thereby increasing the flexibility of base station deployment and reducing transmission construction costs.

[0065] The base station used in the present invention is a 4G / 5G full-network base station, which can provide communication services to other mobile phone users nearby while covering the power terminals.

[0066] The above signaling process is shown in Figure 4 The dashed box shows the special scheduling method implemented by the base station for this situation. If the scheduling priority is lower than that of other power terminals, the user will be scheduled normally if the backhaul link is stable and not congested.

[0067] It should be noted that, in the embodiment of the present invention, if the resource scheduling optimization method for the above-mentioned intelligent power distribution terminal is implemented in the form of a software function module and sold or used as an independent product, it can also be stored in a computer-readable storage medium.
