Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, apparatus, and computer device for switching a cell voice mode. Background Art

[0002] Among the current voice modes for 5G users, there are two common voice modes: VONR (Voice Over New Radio) and EPSFB (Enhanced Packet System FallBack). The choice of voice mode is mainly affected by the terminal capabilities and cell parameter configuration. The network parameters are compared by comparing the current user's 5G coverage with the 5G single-cell voice mode adaptation threshold. If the threshold is greater than or equal to the adaptation threshold, VONR is used, otherwise EPSFB is used (if the terminal does not support VONR, EPSFB is used directly). At present, the voice mode adaptation threshold configuration of a single 5G cell in a large network has the following shortcomings: 1. The large network performs a unified voice mode adaptation threshold configuration for a single 5G cell, without considering the differences between different cells, resulting in differences in the voice mode adaptation threshold of a single 5G cell. 2. Regarding complaints about the voice mode adaptation threshold of a 5G cell, the threshold is simply adjusted for a single user to resolve user complaints. The adjusted threshold is not the optimal threshold at the cell level. 3. Manual testing is required for each cell, followed by configuration of a voice mode adaptation threshold appropriate for that cell. However, due to the large scale of communication facilities, manual testing and configuration are very labor-intensive and time-consuming. Summary of the Invention

[0032] Figure 2 is a flow chart of a method for switching a cell voice mode according to an embodiment of the present application, such as Figure 2 As shown, the method includes the following steps:

[0033] Step S202: Obtain packet loss rate data and measurement report data of multiple users in the network slice respectively;

[0034] In step S202, the packet loss rate data of the user in the network slice can be obtained by identifying the packet loss rate of all network slices in which the user uses the IMS (IP Multimedia Subsystem) network.

[0035] Step S204: Associating the packet loss rate data with the cell ID and the measurement report data to obtain an initial data set, wherein the initial data set includes at least: packet loss rates, cell IDs, and average reference signal received powers corresponding to multiple users;

[0036] Specifically, the packet loss rate in the network slice is associated with the specific cell to obtain a database table of time, user (user ID), packet loss rate, base station and cell ID.

[0037] The user's measurement report data can be pushed northward by the network management MR (Measurement Report) data, and the association between the user ID, time and MR data can be identified from the measurement report data. It should be noted that since both the 4G network and the 5G network are hard-switched networks, the MR data of the service cell in the MR data is selected, and the MR value of the neighboring cell is directly discarded to obtain the initial data set.

[0038] Step S206, deleting the data in the cell handover period from the initial data set to obtain a processed data set;

[0039] Step S208, filtering out users in each cell whose locations remain unchanged within a preset period of time from the processed data set, and determining them as target users;

[0040] Step S210: determining a reference signal received power fluctuation curve of the target user of each cell according to the reference signal received power of the target user, and determining a reference signal received power threshold value of each cell based on the reference signal received power fluctuation curve of each cell;

[0041] Step S212: Switch the voice mode of each cell according to the reference signal receiving power threshold of each cell.

[0042] Through the above steps S202 to S212, the packet loss rate data and measurement report data of multiple users in the network slice are respectively obtained; the packet loss rate data is associated with the cell number and the measurement report data to obtain an initial data set, wherein the initial data set at least includes: the packet loss rate, cell number and average reference signal received power corresponding to multiple users; the data in the cell switching period in the initial data set is deleted to obtain a processed data set; the users whose positions in each cell do not change within the preset period are filtered out from the processed data set and determined as target users; the reference signal received power of each target user is determined according to the reference signal received power of the target user. The reference signal received power fluctuation curve of the target user in the cell is determined, and the reference signal received power threshold value of each cell is determined based on the reference signal received power fluctuation curve of each cell; the voice mode of each cell is switched according to the reference signal received power threshold value of each cell, thereby achieving the purpose of setting an adaptive threshold value for each cell respectively, and then switching the voice mode according to the adaptive threshold value of each cell, thereby achieving the technical effect of improving the accuracy of voice mode switching, and thus solving the technical problem in the related art that the voice mode switching accuracy is low due to ignoring the differences between different cells and adopting a unified threshold value. The following is a detailed description.

[0043] In some embodiments of the present application, the specific steps of associating the packet loss rate data with the cell number and the measurement report data to obtain the initial data set are as follows: obtain the cell number and user corresponding to the packet loss rate data, and associate the packet loss rate data with the corresponding cell number, user and time corresponding to the network slice to obtain the cell number, packet loss rate data and time corresponding to the network slice corresponding to multiple users; obtain multiple measurement report data of the user in the network slice, and obtain the reference signal receiving power in each measurement report data to obtain multiple reference signal receiving powers of the user in the network slice; obtain the average value of multiple reference signal receiving powers in the network slice to obtain the average reference signal receiving power in the network slice; associate the user with the average reference signal receiving power to obtain the initial data set.

[0044] Specifically, since there is only one packet loss rate value in a network slice, and each network slice contains multiple MR data uploaded by multiple sampling points, it is necessary to average the reference signal received power RSRP in the multiple MR data, as shown in the following formula:

[0045]

[0046] Where x p represents the RSRP mean, x i Indicates the RSRP value reported in each MR data in the network slice, and n indicates the total number of MR sampling points.

[0047] Based on the user ID, the packet loss rate corresponding to the time is associated with the MR average. Therefore, a database table of time, number, packet loss rate, base station number, cell number and average RSRP can be output.

[0048] It should be noted that the time can be the time period corresponding to the network slice.

[0049] Since hard switching in 4G and 5G networks is an important factor leading to frequent packet loss of user voice, the relationship between the RSRP value and the packet loss rate of a single cell will become particularly complicated after the switching situation is introduced; in order to eliminate the impact of switching, the data of the switching situation in the network slice is cleaned and eliminated in an embodiment of the present application, thereby eliminating the impact of the switching situation. The specific steps are as follows: deleting the data corresponding to the user with cell switching action in the initial data set to obtain a processed data set, including: determining the user with cell switching action in the initial data set as the first user; obtaining the time period for the first user to perform the cell switching action; deleting the data corresponding to the time period for the first user to perform the cell switching action from the initial data set to obtain the processed data set.

[0050] In some embodiments of the present application, the specific steps of determining the reference signal received power fluctuation curve of each cell based on the reference signal received power of the target user are as follows: obtaining the target user in each cell, and obtaining multiple reference signal received powers of the target user within a target time period; using a preset discrete normal probability function to fit the multiple reference signal received powers to obtain the reference signal received power fluctuation curve of each cell.

[0051] Specifically, since the MR data reported by 5G cell users does not have longitude and latitude information, it is impossible to accurately determine whether the user's location has moved. In the embodiment of the present application, whether the user's location is fixed within a preset period of time is determined by whether the user continuously uses a fixed home broadband within a preset period of time; thereby collecting RSRP data of users with fixed locations (target users). In order to describe the fluctuation of the signal, the present application uses a preset discrete normal probability function to describe the distribution of RSRP value changes for users with fixed locations across the entire network. The formula is as follows:

[0052]

[0053] Where x brepresents the value of the random variable (the RSRP value of a user with a fixed location), μ is the mean of the normal distribution (the expected value of the normal distribution, which describes the variation in RSRP values and has an expected value of 0), and determines the center of the distribution. σ is the standard deviation of the normal distribution, which determines the shape of the distribution; a larger standard deviation results in a flatter curve. The formula for the normal probability function is then output using a nonlinear least squares fit. Nonlinear least squares finds the best function that matches the data by minimizing the sum of squared errors.

[0054] After obtaining the reference signal received power fluctuation curve of each cell, the specific steps for determining the reference signal received power threshold value of each cell based on the reference signal received power fluctuation curve of the target user of each cell are as follows: obtaining the packet loss rate corresponding to the average value of each reference signal received power from the processed data set; generating a target curve in which the packet loss rate varies with the average value of the reference signal received power based on the packet loss rate corresponding to the average value of each reference signal received power; determining the target reference signal received power corresponding to the preset packet loss rate based on the target curve; and determining the reference signal received power threshold value of each cell based on the target reference signal received power.

[0055] It should be noted that there are multiple packet loss rates corresponding to the average value of each reference signal received power. The multiple packet loss rates corresponding to the average value of each reference signal received power are averaged, as shown in the following formula:

[0056]

[0057] Where y p Represents the mean packet loss rate corresponding to a certain RSRP, y i Represents all packet loss rates corresponding to a certain RSRP, and m represents the total number of packet loss rate sampling points corresponding to a certain RSRP.

[0058] It can be understood that the target change curve is used to represent a curve showing that the average value of the packet loss rate corresponding to the average value of the reference signal received power changes with the average value of the reference signal received power.

[0059] In some embodiments of the present application, the reference signal received power threshold value of each cell is determined based on the target reference signal received power, including: determining the reference signal received power of the target users of each cell at different times based on the reference signal received power fluctuation curve of the target users of each cell; determining the sum of the target reference signal received power and the reference signal received power of the target users of each cell at different times as the initial value of the reference signal received power threshold value of each cell at different times; obtaining the average value of the reference signal received power of users in the entire network; and determining the reference signal received power threshold value of each cell based on the average value of the reference signal received power of users in the entire network and the initial value of the reference signal received power threshold value of each cell at different times.

[0060] Taking the preset packet loss rate of 2% as an example, the target reference signal received power when the packet loss rate is 2% is obtained, and the initial value of the reference signal received power threshold is equal to the target reference signal received power + the reference signal received power of the target user (fixed position user) in the cell.

[0061] Since user signal fluctuations vary across cells, if the signal reference power value of a fixed-location user (target user) in a cell is X dB greater than the average network-wide reference signal received power, the voice mode adaptation threshold is increased by X dB.

[0062] Specifically, the difference between the average value of the reference signal received power of users in the entire network and the reference signal received power of the target users of each cell at different times is obtained; when the difference is greater than zero, the reference signal received power threshold value of each cell is determined to be the sum of the initial value of the reference signal received power threshold value and the difference; when the difference is less than zero, the reference signal received power threshold value of each cell is determined to be the initial value of the reference signal received power threshold value.

[0063] like Figure 3 As shown, the embodiment of the present application also provides a method for adjusting the cell threshold value, such as Figure 3 As shown, it includes: step 1, identifying the slice-level packet loss rate of the user; step 2, associating the packet loss rate with MR; step 3, eliminating abnormal packet loss rate and RSRP mean data; step 4, analyzing the signal fluctuation of users with fixed positions; step 5, outputting the adaptive threshold of the optimal voice mode of a single 5G cell.

[0064] Specifically, the downlink packet loss rate of all voice users' network slices is first identified using voice network slice data from DPI (Deep Packet Inspection). Next, based on the user number, the MR data reported by the network management system to the northbound network is correlated with the network slice packet loss rate data to identify the average RSRP value and downlink packet loss rate for each individual user across all network slices. Because handovers between cells may occur within a network slice, packet loss can be caused by a key interfering factor, hard network handovers. To eliminate this interfering factor, data involving cell handovers within the network slice is removed to ensure the accuracy of the analysis results. The processed RSRP and packet loss rate data are correlated and analyzed, and the RSRP value at the 2% packet loss point is output. Due to the volatility of mobile user signals, to eliminate voice packet loss caused by switching to 4G due to 5G signal fluctuations, the adaptive threshold needs to be greater than or equal to the RSRP value corresponding to the fluctuation value + 2% packet loss rate. A discrete normal distribution probability function is introduced to analyze the signal fluctuations of fixed-position users, thereby deriving the signal fluctuation value of fixed-position users in all 5G cells of the entire network. This results in the initial value of the voice mode adaptive threshold for a single 5G cell (the RSRP value corresponding to the fluctuation value + 2% packet loss rate). Finally, based on the fluctuation value of fixed-position users in a single 5G cell and the fluctuation value of all 5G cells in the entire network, the voice mode adaptive threshold for a single 5G cell is obtained (if it is greater than the threshold, the threshold increases; if it is less than or equal to the threshold, the threshold remains unchanged).
