[0047] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0048] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0049] Currently, there are three main ways to implement EPS FB frequency delivery: switching-based, redirection-based, and busy redirection-based. All three methods require pre-configured frequencies, and the terminal selects them randomly. The frequency selection is limited and there is no guarantee that the most available frequency is selected, which makes fallback failure easy.

[0050] In order to solve the problems in the prior art, the embodiments of the present application provide a method, apparatus, device and computer storage medium for determining a fallback frequency point.

[0051] Figure 1 FIG. 1 is a flow chart showing a method for determining a fallback frequency point according to an embodiment of the present application. Figure 1 As shown, the method may include the following steps:

[0052] S110: The target terminal sends a frequency fallback request to the base station, where the frequency fallback request includes location information of the target terminal.

[0053] In some embodiments, when a target terminal needs to conduct voice or other services, it sends a frequency fallback request to the base station. The frequency fallback request includes the target terminal's location information. The target terminal's location information includes timing advance (TA) and angle of arrival (AOA). TA data can be used to determine the distance between the terminal and the base station; AOA data can be used to determine the terminal's position relative to the base station.

[0054] S120: The base station receives a frequency fallback request sent by the target terminal, and determines frequency information of the target terminal according to the frequency fallback request, where the frequency information includes frequency priority information.

[0055] In some embodiments, the base station determines the area where the target terminal is located based on the location information in the received frequency fallback request from the target terminal, and further determines the frequency and frequency priority information of the area. The frequency and frequency priority information are used to enable the target terminal to select a frequency with a high priority as the fallback frequency.

[0056] S130. The base station sends frequency information to the target terminal, where the frequency information includes frequency priority information.

[0057] In some embodiments, after the target terminal sends a fallback request to the base station, it receives a request reply from the base station. The request reply includes frequency information for the area where the terminal is located, including the frequency and its priority data. The frequency priority can be used to indicate the fallback success rate of the frequency.

[0058] In some embodiments, the number of frequency points received by the target terminal is 3. The specific number can be set according to actual conditions and is not limited here.

[0059] S140: Determine a fallback frequency of the target terminal based on the location information of the target terminal and the priority information of the frequency.

[0060] In some embodiments, the area where the target terminal is located can be determined based on the location information of the target terminal, and a frequency with a high priority is selected as the fallback frequency of the target terminal based on the received frequency data of the area where the target terminal is located.

[0061] The method for determining a fallback frequency provided in an embodiment of the present application can receive frequency information including frequency priority information from a base station after a target terminal sends a frequency fallback request including location information to a base station. The target terminal can select a high-priority frequency as the fallback frequency based on the frequency information, thereby improving the target terminal's frequency fallback success rate.

[0062] In some embodiments, based on the TA data, the distance between the terminal and the base station can be determined; based on the AOA data, the orientation of the terminal relative to the base station can be determined. Specifically, the following steps are included:

[0063] TA algorithm: The distance between the target terminal and the base station can be determined based on the TA (a) and weight (w) in the instantaneous model within a period (T). Figure 2 The TA judgment calculation formula is as follows:

[0064]

[0065] Among them, i is the total number of TA sampling points, T is the sampling period, and t is the scheduling period, ranging from 1 to is the weighted sum of TA based on the sampling period T and weight, W i is the weight, A i is the TA amount; is the TA sum based on the sampling period T, which is used for the calculation of Cava and the selection of TA groups; Cava is the weighted TA within the sampling period T, which is used for scene judgment and specific TA groups.

[0066] AOA algorithm: The AOA (o) and weight (w) in the instantaneous model are measured within a period (T). Based on the measurement results, the position information of the target terminal and the base station can be determined, such as Figure 3 The judgment calculation formula is as follows:

[0067]

[0068] Where i is the total number of AOA sampling points, T is the sampling period, and t is the scheduling period, ranging from 1 to is the weighted sum of TA based on the sampling period T and weight, W i is the weight, O i is the AOA quantity; is the AOA sum based on the sampling period T, which is used for the calculation of Cavo and the selection of the AOA group; Cavo is the weighted AOA within the sampling period T, which is used for scene judgment and AOA group selection.

[0069] According to the calculated distance information between the target terminal and the base station and the orientation information between the target terminal and the base station, the geographic grid where the target terminal is located can be determined. Figure 2 and Figure 3 The overlapping part of the area shown is the grid where the target terminal is located, such as Figure 4 shown.

[0070] In some embodiments, before the base station determines the frequency information of the target terminal according to the frequency fallback request, it also includes: obtaining sampling point data, the sampling point data is the data of the Minimization of Drive Test (MDT) sampling points reported by multiple terminals, and the data of the MDT sampling points include the location information of the multiple terminals and the frequency information of the multiple terminals and other data; mapping the sampling point data to the geographic grid; determining the frequency ratio within the geographic grid based on the sampling point data; determining the priority of the frequency of the geographic grid based on the frequency ratio within the geographic grid; determining the fallback frequency of the geographic grid based on the priority of the frequency of the geographic grid. Specifically, the base station obtains historical sampling point data reported by multiple terminals, and the historical sampling point data includes the location information and frequency information of multiple terminals and other data, wherein the location information of the terminal includes the TA and AOA data of the terminal. Based on the TA data and AOA data of multiple terminals, the geographic grid where the multiple terminals are located can be determined, and the sampling point data corresponding to the terminal can be mapped to the geographic grid where it is located, such as Figure 5 As shown. The frequency ratio of the terminals in the geographic grid is determined, and the frequency priorities are determined from high to low according to the frequency ratio. Further, the fallback frequency of the current geographic grid is determined based on the obtained frequency priority information.

[0071] In some embodiments, before mapping the sampling point data to the geographic grid, the method further includes dividing the geographic grid based on angle and distance, with the cell azimuth as the center. The sampling point data includes TA and AOA data of multiple terminals, and the terminal location can be determined based on TA and AOA.

[0072] In some embodiments, mapping the sampling point data to the geographic grid includes mapping the sampling point data to the geographic grid by a ray method.

[0073] In some embodiments, the sampling point data includes the terminal's location information, cell occupancy information, and neighboring cell information, wherein the cell occupancy information includes the terminal's frequency information.

[0074] In some embodiments, determining the frequency point ratio within a geographic grid based on sampling point data further includes: mapping the sampling point data in the geographic grid to a first grid, where the first grid is a grid further divided based on the geographic grid; determining the frequency points of the first grid based on the sampling point data in the first grid; and determining the frequency point ratio within the geographic grid based on the frequency points of the first grid. Specifically, the geographic grid is further divided into 5×5m grids, and the sampling point data in the geographic grid is mapped to the first grid, such as Figure 6 Based on the frequency point ratio in the first grid, the frequency point with the largest ratio is determined as the frequency point of the first grid. Based on the frequency points of multiple first grids in the geographic grid, the frequency point ratio in the geographic grid is determined.

[0075] The method for determining the fallback frequency provided in the embodiment of the invention of the present application can determine the frequency data in the geographic grid by obtaining the sampling point data of multiple terminals, and further divide the geographic grid into the first grid based on the geographic grid. The frequency of the first grid is determined by the frequency ratio within the first grid, and then the frequency and frequency priority information of the geographic grid are determined according to the frequency ratio of multiple first grids in the geographic grid. Among them, the division of the first grid can reduce the impact of a large number of repeated sampling points in a smaller range on the overall data. The base station determines the frequency priority of the grid where the target terminal is located based on the location information of the target terminal, so that the target terminal can obtain more accurate and better frequency data, thereby improving the success rate of fallback.

[0076] Based on the above-mentioned method for determining the fallback frequency, this application also proposes a device for determining the fallback frequency, the specific contents of which are as follows:

The target terminal selects the frequency with the highest priority as the fallback frequency, thereby greatly improving the success rate of the target terminal's frequency fallback.

[0083] The receiving module 810 is configured to receive, by the base station, a frequency fallback request sent by a target terminal, where the frequency fallback request includes location information of the target terminal.

[0084] The determination module 820 is used for the base station to determine the frequency information of the target terminal according to the frequency fallback request. The frequency information includes frequency priority information, which is used for the target terminal to determine the fallback frequency of the target terminal based on the target terminal location information and frequency priority information.

[0085] The sending module 830 is used for the base station to send frequency information to the target terminal.

The base station sends the frequency information of the area where the target terminal is located to the target terminal, so that the target terminal selects the fallback frequency based on the frequency and frequency priority data included in the frequency information, thereby improving the success rate of frequency fallback.

[0087] In some embodiments, the apparatus further includes an acquisition module 801 and a mapping module 802.

[0088] In some embodiments, determining the frequency point proportion within a geographic grid based on sampling point data includes: mapping the sampling point data in the geographic grid to a first grid, where the first grid is a grid further divided based on the geographic grid; determining the frequency points of the first grid based on the sampling point data within the first grid; and determining the frequency point proportion within the geographic grid based on the frequency points of the first grid.

[0089] In some embodiments, the apparatus further includes a partitioning module 806. The partitioning module 806 is configured to partition the geographic grid based on angle and distance, with the cell azimuth as the center, before mapping the sampling point data to the geographic grid.
