Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, server and electronic equipment for sending handover measurement parameters. Background Art

[0002] In mobile communication systems, to improve spectrum resource utilization and overall system capacity, the system's RF power must be limited to a certain range. When a user device leaves cell A and enters cell B, the signal it receives from cell A becomes weaker, while the signal from cell B becomes stronger. To ensure the user device's communication quality, the user device must be handed off from the original base station to a base station with a stronger signal, thereby ensuring seamless service connectivity. The configuration of handover parameters directly impacts the overall system performance. Field test results show that handovers often exhibit abnormalities. For example, in urban areas, the handover area often exhibits corner effects and pinpoint effects, where the signal strength of the current cell drops sharply with location, or the signal strength of the target cell rises sharply with location. The default handover parameter configuration results in many handovers not being triggered in a timely manner, resulting in a sharp deterioration in the signal-to-noise ratio, which can cause dropped calls.

[0003] In existing technologies, handover parameters for a cell are determined through field testing, empirical data, or by traversing all possible parameter combinations. These parameters are then distributed to the base station via the operations management and maintenance center. User equipment in each cell then performs handovers based on these parameters. However, these solutions require manual parameter acquisition, which requires significant manual intervention, wastes air interface resources, and is prone to handover failures. In real-life scenarios, handovers occur numerous times daily, making the vast amount of data difficult to effectively utilize. Therefore, existing solutions suffer from low handover efficiency during user equipment handovers. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1-4 The present invention describes a method, device, server, and electronic device for sending handover measurement parameters.

[0035] like Figure 1 As shown, the present invention provides a method for sending handover measurement parameters, including:

[0036] Step 110: Obtain handover related parameters and a measurement report of the target area, input the handover related parameters and the measurement report into a preset simulated annealing model, and obtain handover measurement parameters and a handover parameter delivery function.

[0037] It can be understood that the handover measurement parameter sending method provided by the present invention is applied to a server, and the handover measurement parameter sending method provided by the present invention is executed by the server.

[0038] The measurement report is uploaded by the user equipment (UE). The handover measurement parameters are parameters such as the base station signal strength corresponding to the target area. The handover-related parameters are parameters configured by the base station when the user equipment is handed over in the target area, that is, the handover-related configuration parameters.

[0039] By using the simulated annealing model and the robustness of the nonlinear algorithm, the relationship between the handover-related configuration parameters and important indicators such as the call drop rate and handover delay during the handover process is derived, and then the relevant parameters suitable for each area are obtained.

[0040] Step 120: Based on the handover parameter delivery function, send the handover measurement parameter to the base station in the target area.

[0041] It can be understood that the handover parameter sending function of the target area corresponds to the handover measurement parameter, and the handover measurement parameter can be sent to the base station in the target area.

[0042] In some embodiments, the measurement report includes a handover success rate, a handover delay, and a call drop rate during the handover process in the target area.

[0043] It is understandable that the measurement report includes the reference signal received power of the abnormal cell and the reference signal received power of the source cell measured by the user equipment before initiating the handover in the abnormal scenario handover area; the success rate of the handover in the area and the handover delay, and the call drop rate during the handover process.

[0044] In some embodiments, the sending the handover measurement parameter to the base station in the target area based on the handover parameter delivery function includes:

[0045] The handover measurement parameter is sent to an operation and maintenance management system based on the handover parameter sending function, so that the handover measurement parameter is sent to a base station in the target area through the operation and maintenance management system.

[0046] It can be understood that the operation and maintenance management system (OAM, Operation Administration and Maintenance) is set in the server. After obtaining the switching related parameters of the target area, the switching parameter sending function sends the switching related parameters to the operation and maintenance management system, and then sends them to the base station in the target area through the operation and maintenance management system, thereby improving the effectiveness of user terminal switching in the target area.

[0047] In some embodiments, after sending the handover measurement parameter to the base station in the target area, the handover measurement parameter sending method further includes:

[0048] Obtaining current indicator data corresponding to the base station;

[0049] Based on the comparison result between the current indicator data and the target indicator data, feedback correction is performed on the simulated annealing model to improve the convergence speed of the algorithm solution in the simulated annealing model;

[0050] The current indicator data includes the current handover success rate, the current handover delay, and the call drop rate during the current handover process;

[0051] The target indicator data includes a target handover success rate, a target handover delay, and a target call drop rate during the handover process.

[0052] It is understood that after the handover measurement parameters are sent to the base station, the data acquisition system can collect the current handover success rate, current handover delay, and call drop rate during the current handover process in the target area. The current handover success rate is subtracted from the target handover success rate to obtain a first difference value, the current handover delay is subtracted from the target handover delay to obtain a second difference value, and the call drop rate during the current handover process is compared with the target call drop rate to obtain a third difference value. When the first difference value is greater than a first preset threshold value, the simulated annealing model is feedback-corrected based on the first difference value. When the second difference value is greater than a second preset threshold value, the simulated annealing model is feedback-corrected based on the second difference value. When the third difference value is greater than a third preset threshold value, the simulated annealing model is feedback-corrected based on the third difference value.

[0053] In some embodiments, inputting the handover-related parameters and the measurement report into a preset simulated annealing model to obtain the handover measurement parameters and the handover parameter delivery function includes:

[0054] Inputting the handover related parameters and the measurement report into a preset simulated annealing model, so as to perform an annealing simulation on the handover related parameters based on the simulated annealing model to obtain handover measurement parameters;

[0055] The switching measurement parameter is used as the input value of the function required to build the simulated annealing model, and the measurement report is used as the target value of the function required to build the simulated annealing model. The function required to build the simulated annealing model is trained to obtain the switching parameter sending function.

[0056] It can be understood that a simulated annealing model is established based on the large amount of data collected in the data acquisition system (i.e., handover-related parameters and measurement reports). The established simulated annealing model then solves the handover measurement parameters for the target area using this large amount of data. The different handover measurement parameters configured for that area are used as input parameters for the simulated annealing model. Important indicators such as the call drop rate, handover success rate, and handover delay during the handover process serve as target values ​​for the simulated annealing model. Calculations are performed using the large amount of data obtained during the acquisition process to obtain a suitable handover parameter delivery function for that area.

[0057] In some embodiments, the simulated annealing model is trained based on different historical switching related parameters corresponding to the target area.

[0058] It can be understood that the simulated annealing model is trained based on the handover related parameters of different historical stages corresponding to each base station in the target area.

[0059] The simulated annealing model's algorithm is based on the principle of solid annealing. A solid is heated to a sufficient temperature and then slowly cooled. During heating, the particles within the solid become disordered as the temperature rises, increasing its internal energy. However, as it cools, the particles gradually become ordered, reaching equilibrium at each temperature and finally reaching the ground state at room temperature, where the internal energy is minimized. Solid annealing is used to simulate combinatorial optimization problems, with the internal energy E modeled as the objective function value f and the temperature T evolving into the control parameter t. This results in a simulated annealing algorithm for solving combinatorial optimization problems: Starting with an initial solution i and an initial value t for the control parameter, the algorithm repeats the iterative process of "generating a new solution → calculating the objective function difference → accepting or rejecting" for the current solution, gradually decaying the value of t. The current solution at the end of the algorithm is the approximate optimal solution. This is a heuristic random search process based on the Monte Carlo iterative solution method. The annealing process is controlled by a cooling schedule, which includes the initial value t of the control parameter and its decay factor Δt, the number of iterations L for each value of t, and the stopping condition S.

[0060] In other embodiments, the method for sending the switching measurement parameters is as follows: Figure 2 As shown, the data acquisition system collects the switching related parameters and measurement reports of the target area. The simulated annealing calculation system calculates the switching measurement parameters and the switching parameter sending function based on the switching related parameters and measurement reports of the target area. In the parameter sending system, the switching measurement parameters are sent to the base station based on the switching parameter sending function. Finally, in the parameter verification system, based on the comparison results between the current indicator data of the base station and the target indicator data, the simulated annealing model is feedback-corrected to improve the convergence speed of the algorithm solution in the simulated annealing model.

[0061] In summary, the handover measurement parameter sending method provided by the present invention includes: obtaining handover-related parameters and measurement reports of the target area, inputting the handover-related parameters and the measurement reports into a preset simulated annealing model to obtain handover measurement parameters and a handover parameter sending function; based on the handover parameter sending function, sending the handover measurement parameters to the base station of the target area.

[0062] In the handover measurement parameter sending method provided by the present invention, the handover-related parameters and measurement report of the target area are obtained, and the handover-related parameters and measurement report are input into a preset simulated annealing model. Based on the robustness of the nonlinear algorithm of the simulated annealing model, the relationship between the handover-related parameters in the target area and the important indicators in the measurement report is derived, and then the handover measurement parameters suitable for each base station in the target area can be solved. The handover measurement parameters are sent to the base station in the target area through the handover parameter sending function. The entire process does not require manual intervention, thereby improving the effectiveness of user equipment during handover.

[0063] In the target area, during the handover process of a large number of user devices, due to the different configurations of handover measurement parameters, the user devices' handover success rates, handover drop rates, and handover delays vary, generating a large amount of data. Using a simulated annealing model, the function between the handover measurement configuration relationship and the handover-related KPI indicator data is determined. The handover measurement parameters are optimized, resulting in a significant improvement in the handover performance between normal cells.
