Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a ping-pong switching suppression method, device, equipment, readable storage medium and computer program product. Background Art

[0002] In a wireless communication system, when a terminal is at the edge of a serving cell, the signal strength of the serving cell becomes weaker, while the signal strength of the adjacent cell becomes stronger. When the reference signal strength of the adjacent cell is greater than the reference signal strength of the serving cell and the difference between the two is greater than or equal to the preset difference set by the switching threshold, the terminal will report a measurement report, and the base station of the serving cell will perform cell switching based on the measurement report. However, due to the weak coverage at the cell edge and the large fluctuations in the coverage signal quality, ping-pong switching is prone to occur, causing the terminal to frequently switch between two or more cells, affecting the data transmission quality.

[0003] At present, in the related technology, the following methods are used to suppress ping-pong switching: one is to use a fuzzy logic model to optimize the hysteresis threshold of the switching; the other is to record the number of times the terminal switches to the target cell. When the terminal wants to switch to the target cell again, it will judge whether it is in a ping-pong switching state based on the recorded number of times it switches to the target cell. If so, it will no longer send the corresponding measurement report, thereby suppressing the occurrence of the switching event. The models used in the first method mentioned above are all pre-defined parameter models. Therefore, this method can only be limited to suppressing the occurrence of ping-pong switching in some static scenarios. The triggering conditions of the second method mentioned above are relatively rigid and cannot adapt to changes in the environment.

DETAILED DESCRIPTION

[0025] In a wireless communication system, when a terminal is at the edge of a serving cell, the signal strength of the serving cell weakens and the signal strength of the adjacent cell increases. When the reference signal strength of the adjacent cell is greater than the reference signal strength of the serving cell, and the difference between the reference signal strength of the serving cell and the reference signal strength of the target cell is greater than or equal to the preset difference set by the switching threshold, the terminal will report a measurement report, and the base station of the serving cell will perform cell switching based on the measurement report. However, due to the weak coverage at the cell edge and the large fluctuations in the coverage signal quality, ping-pong switching is prone to occur, causing the terminal to frequently switch between two or more cells, affecting the data transmission quality.

[0026] In a typical handover process, the network sends measurement configuration information to the terminal, and the terminal determines whether the measured signal meets the measurement report threshold and other conditions. If so, the terminal reports the corresponding measurement report. After the network receives the measurement report of the terminal, it sends a handover command to instruct the terminal to switch. After receiving the handover command, the terminal performs downlink and uplink synchronization with the target cell. Uplink synchronization is achieved by the random access process. After the random access is successful, the terminal starts service data transmission in the target cell.

[0027] At present, the following methods are used to suppress ping-pong switching: one is to use a fuzzy logic model to optimize the hysteresis threshold of switching, thereby suppressing the corresponding ping-pong switching phenomenon. The other is to determine whether it is in a ping-pong switching state based on the number of times the terminal switches to the target cell, and suppress the occurrence of ping-pong switching events.

[0028] Specifically, for the first method, see Figure 1, which shows a flowchart of the traditional use of fuzzy logic model to optimize the hysteresis threshold of switching to suppress the ping-pong switching phenomenon. The reference signal received power RSRP, reference signal received quality RSRQ, and train speed v in the measurement report are selected as factors for optimizing the hysteresis threshold. First, RSRP, RSRQ, and v are input into the system for fuzzification processing, and then fuzzy reasoning is performed according to fuzzy rules and membership functions. Finally, the result is defuzzified and the optimized switching hysteresis threshold value Hys is output. Finally, the corresponding switching strategy is executed according to the hysteresis threshold output by the model. This scheme first fuzzifies the reference signal received power RSRP, reference signal received quality RSRQ, train speed v and other parameters in the UE (user equipment) measurement report through a pre-designed membership function, and then fuzzy reasoning is performed on the hysteresis threshold according to the corresponding fuzzy adaptive rule base, and then the fuzzy hysteresis threshold is defuzzified, and finally the switching process is performed as the corresponding switching hysteresis threshold. The models used in this solution are all pre-defined parameter models, including corresponding parameter membership functions, fuzzy adaptive rule bases, and defuzzified membership functions. These parameter models will determine the final output of the hysteresis threshold, thereby affecting the occurrence of switching. However, in real scenarios, these parameter models cannot adapt to all transmission environments. Artificially adjusting the corresponding parameter models according to environmental parameters not only requires a lot of cost, but the environment will also change over time. Therefore, this method can only be limited to suppressing the occurrence of ping-pong switching in some static scenarios.

[0029] The second method is to record the number of times the mobile terminal switches to the cell it left when performing the handover. When it wants to switch to the target cell (i.e., the cell it left above) again, it will determine whether the mobile terminal is in a ping-pong handover state based on the number of times it switches to the cell it left contained in the historical information. If so, it will no longer send the corresponding test report, thereby suppressing the occurrence of the handover event. That is, this method determines whether the current terminal is in a ping-pong handover state by recording the number of times it enters a certain cell, thereby deciding whether to send the corresponding measurement report and perform handover between cells. The triggering conditions of this method during execution are relatively rigid and not flexible enough, and cannot achieve universality to the environment.

[0030] To this end, the present application provides a ping-pong switching suppression method, apparatus, device, readable storage medium and computer program product for dynamically adjusting the hysteresis threshold so that the ping-pong switching suppression method has universal applicability.

[0031] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0032] See also Figure 2 , which shows a flow chart of a ping-pong switching suppression method provided in an embodiment of the present application. The ping-pong switching suppression method provided in an embodiment of the present application may include: S11: Obtain the hysteresis threshold corresponding to the current cell switching of the terminal.

[0033] It should be noted that the executor of the ping-pong switching suppression method provided in the embodiment of the present application may be a ping-pong switching suppression device, a ping-pong switching suppression equipment, a readable storage medium, a computer program product or a terminal, etc., wherein the readable storage medium or the computer program product may be located in the terminal. The embodiment of the present application takes the executor of the ping-pong switching suppression method as the terminal as an example for explanation. The terminal mentioned in the embodiment of the present application may specifically be a mobile terminal.

[0034] First, when the terminal is located at an edge cell, the signal strength of two or more cells changes unsteadily, and ping-pong switching is prone to occur. In order to suppress the ping-pong switching phenomenon, corresponding parameters can be configured in advance in the terminal, so as to deal with the occurrence of ping-pong switching based on the corresponding parameters pre-configured in the terminal. Among them, the corresponding parameters pre-configured in the terminal may include an initial hysteresis threshold R0, that is, it can be initially determined whether the terminal can perform cell switching based on the initial hysteresis threshold R0.

[0035] In the embodiment of the present application, when the terminal currently switches cells, the total number of times n that the terminal switches cells can be increased by 1 (the initial value of n is 0) to facilitate counting the total number of times n that the terminal switches cells. In addition, the hysteresis threshold R corresponding to the current cell switching of the terminal can also be obtained. n-1 (n starts from 1), so as to determine the hysteresis threshold corresponding to the next cell switching of the terminal according to the hysteresis threshold corresponding to the current cell switching of the terminal.

[0036] Among them, the hysteresis threshold is the critical value that the signal strength difference between two cells must meet when the terminal occurs in the cell. Specifically, when the signal strength difference between the target cell and the current cell (the current cell is the source cell, that is, the cell currently connected to the terminal) (the signal strength of the target cell is greater than the signal strength of the current cell) is greater than or equal to the corresponding hysteresis threshold, the terminal will switch from the current cell to the target cell.

[0037] S12: Determine the hysteresis threshold corresponding to the next cell switching of the terminal according to the hysteresis threshold corresponding to the current cell switching of the terminal; the hysteresis threshold corresponding to the next cell switching of the terminal is greater than the hysteresis threshold corresponding to the current cell switching of the terminal.

[0038] Get the hysteresis threshold R corresponding to the current cell switching of the terminal n-1 After that, the corresponding hysteresis threshold R when the terminal currently switches cells can be used. n-1 Determine the hysteresis threshold R corresponding to the next cell switching of the terminal n , and the hysteresis threshold R corresponding to the next cell switching of the terminal is determined n Greater than the hysteresis threshold R corresponding to the current cell switching of the terminal n-1 , that is, the hysteresis threshold R corresponding to the current cell switching of the terminal n-1 Based on the above, the hysteresis threshold is increased to obtain the hysteresis threshold R corresponding to the next cell switching of the terminal. n In this way, the hysteresis threshold increases with the increase of the number of terminal switching times, so that the terminal can eventually stay in a certain cell, thereby achieving the effect of suppressing ping-pong switching. Moreover, by adjusting the hysteresis threshold corresponding to the next cell switching according to the hysteresis threshold corresponding to the current cell switching, the hysteresis threshold can be adjusted according to the real-time switching situation, so that the adjustment of the hysteresis threshold is more reasonable and accurate, more suitable for the current transmission environment, and can dynamically adapt to changes in the environment.

[0039] S13: Controlling the cell switching of the terminal according to the corresponding hysteresis threshold when the terminal switches the cell next time.

[0040] Determine the hysteresis threshold R corresponding to the next cell switching of the terminal n After that, the hysteresis threshold R corresponding to the next cell switching of the terminal can be determined. n To control the cell switching of the terminal. Among them, when the corresponding hysteresis threshold R n When it is determined that the terminal will switch cells next, the hysteresis threshold R corresponding to the next cell switching of the terminal can be set. n Determine the hysteresis threshold corresponding to the current cell switching of the terminal, and return to execute step S12, so that the hysteresis threshold is increased on the basis of the hysteresis threshold corresponding to the current cell switching each time the terminal switches a cell, so that the hysteresis threshold corresponding to the next cell switching can be greater than the hysteresis threshold corresponding to the current cell switching, so that the hysteresis threshold becomes larger and larger as the number of switching times increases, thereby suppressing the generation of the corresponding ping-pong effect.

[0041] Specifically, in the initial case, when the terminal in the initial state detects that the difference between the signal strength of the target cell and the signal strength of the current cell is greater than the initial hysteresis threshold R0, the last step of the switching process will be performed normally, that is, the terminal sends a corresponding measurement report to the base station and performs the corresponding switching normally. At this time, the total number of cell switchings n of the terminal can be increased by 1 to record the total number of cell switchings n of the terminal, and the hysteresis threshold of the terminal can be updated after the switching is completed, that is, the hysteresis threshold R1 corresponding to the next cell switching of the terminal can be determined according to the initial hysteresis threshold R0, and R1>R0, so as to raise the corresponding hysteresis threshold, thereby suppressing the subsequent ping-pong switching that may occur. After raising the corresponding hysteresis threshold, the terminal can continue to return to the corresponding initial state (cell switching is completed, the signal strength of the cell is measured, etc.), and then the terminal can be controlled to switch the cell based on the determined hysteresis threshold R1. When the terminal is determined to have switched the cell according to the determined hysteresis threshold R1, the total number of times the terminal switches the cell n can be increased by 1, and after the switching is completed, the corresponding hysteresis threshold R2 for the next cell switching of the terminal can be determined according to the hysteresis threshold R1 corresponding to the current cell switching of the terminal, and R2>R1, so as to raise the corresponding hysteresis threshold..., so as to gradually increase the hysteresis threshold as the number of switching increases, thereby suppressing the occurrence of ping-pong switching. It can be seen from the above process that when the environmental conditions such as the cell signal strength are relatively stable, the terminal will not frequently switch the cell, and accordingly, the update of the hysteresis threshold is not frequent. When the environmental conditions such as the cell signal strength are unstable, the terminal will frequently switch the cell. At this time, the hysteresis threshold will be frequently updated and increase rapidly, so that the cell switching becomes more and more difficult, so as to suppress the occurrence of ping-pong switching.

[0042] Through the above, the hysteresis threshold can be adjusted according to the real-time handover situation, so that the setting of the hysteresis threshold is more reasonable and accurate, more adapted to the current transmission environment (i.e., cell signal level, etc.), and more accurate response to real-time measurement parameters can be achieved, thereby adjusting the corresponding hysteresis threshold. And through the above dynamic adjustment of the hysteresis threshold, it can be adapted to the actual situation of different cell signal strengths, thereby dynamically adapting to environmental changes and achieving universal suppression of ping-pong handover.

[0043] The above-mentioned technical scheme disclosed in the embodiment of the present application increases the hysteresis threshold based on the hysteresis threshold corresponding to the current cell switching of the terminal to obtain the hysteresis threshold corresponding to the next cell switching of the terminal, so as to not only realize that the hysteresis threshold becomes higher and higher as the number of cell switching increases, thereby suppressing the occurrence of ping-pong switching, but also realize dynamic, accurate and flexible adjustment of the hysteresis threshold according to the real-time switching situation, so that the ping-pong switching suppression method can better adapt to the current transmission environment and can dynamically adapt to changes in the environment, thereby making the ping-pong switching suppression method universal and expanding the scope of application of the ping-pong switching suppression method.

[0044] A ping-pong handover suppression method provided in an embodiment of the present application may further include, before determining, according to a hysteresis threshold corresponding to a current cell handover of a terminal, a hysteresis threshold corresponding to a next cell handover of the terminal: Get the total number of cell switchings that occur on the terminal; Determining, according to the hysteresis threshold corresponding to the current cell switching of the terminal, the hysteresis threshold corresponding to the next cell switching of the terminal may include: The hysteresis threshold corresponding to the next cell switching of the terminal is determined according to the total number of times the cell switching occurs at the terminal and the hysteresis threshold corresponding to the current cell switching of the terminal.

[0045] In the embodiment of the present application, according to the hysteresis threshold R corresponding to the current cell switching of the terminal n-1 , determine the hysteresis threshold R corresponding to the next cell switching of the terminal n Previously, the total number of times n of cell switching occurring in the terminal can be obtained by statistics.

[0046] On the basis of the above, the total number of cell switchings of the terminal n and the hysteresis threshold R corresponding to the current cell switching of the terminal can be used. n-1 Determine the hysteresis threshold R corresponding to the next cell switching of the terminal n , so as to dynamically adjust the hysteresis threshold according to the total number of cell switching times n of the terminal, thereby achieving a more reasonable and accurate adjustment of the hysteresis threshold, so that the adjusted hysteresis threshold can be more adapted to the current transmission environment and can better adapt to environmental changes.

[0047] A ping-pong handover suppression method provided in an embodiment of the present application, which determines a hysteresis threshold corresponding to the next cell handover of the terminal according to the total number of cell handovers of the terminal and the hysteresis threshold corresponding to the current cell handover of the terminal, may include: Determine the amount by which the hysteresis threshold is raised according to the total number of cell switchings that occur at the terminal; the amount by which the hysteresis threshold is raised is positively correlated with the total number of cell switchings that occur at the terminal; The hysteresis threshold corresponding to the next cell switching of the terminal is determined according to the hysteresis threshold raising amount and the hysteresis threshold corresponding to the current cell switching of the terminal.

[0048] In an embodiment of the present application, when determining the hysteresis threshold corresponding to the next cell switching of the terminal based on the total number of cell switchings of the terminal and the hysteresis threshold corresponding to the current cell switching of the terminal, the hysteresis threshold increase amount can be first determined based on the total number of cell switchings of the terminal. Among them, considering that the signal strength relationship between the target cell and the source cell is unstable when the initial handover occurs, in order to enable the terminal to find the base station corresponding to the better cell and to achieve the effect of suppressing the occurrence of ping-pong handover, the initial hysteresis threshold raising amount may not be set too large, and the hysteresis threshold raising amount may increase rapidly with the gradual increase in the number of handovers to achieve the suppression effect. For this reason, the hysteresis threshold raising amount ΔR(n) may be positively correlated with the total number of cell handovers of the terminal, that is, when the total number of cell handovers of the terminal is small, the hysteresis threshold raising amount is also small, and as the total number of cell handovers of the terminal increases, the hysteresis threshold raising amount also increases, so as to achieve a small initial hysteresis threshold raising amount (indicating that the handover is not excessively suppressed in the initial stage), so that the terminal can easily find a cell with better signal strength for connection in the initial stage, and when the handover occurs frequently, the hysteresis threshold will increase rapidly to effectively suppress the occurrence of ping-pong handover.

[0049] After determining the hysteresis threshold raising amount ΔR(n), the hysteresis threshold R corresponding to the current cell switching of the terminal can be n-1 Add the hysteresis threshold increase ΔR(n) to determine the hysteresis threshold R corresponding to the next cell switching of the terminal. n , that is, R n =R n-1 +ΔR(n), ΔR(n) is positively correlated with n.

[0050] A ping-pong handover suppression method provided in an embodiment of the present application determines the hysteresis threshold raising amount according to the total number of cell handovers occurring in a terminal, and may include: According to the total number of cell switchings of the terminal and the threshold raising order, an exponential function form or a power function form is used to determine the hysteresis threshold raising amount; When an exponential function is used, the threshold raising order is greater than 1; when a power function is used, the threshold raising order is greater than 0.

[0051] In an embodiment of the present application, the corresponding parameters pre-configured in the terminal may include a threshold raising order F, wherein the threshold raising order F may be set by relevant personnel based on experience or through pre-experiments.

[0052] The specific process of determining the hysteresis threshold raising amount according to the total number of cell switchings of the terminal may be: according to the total number of cell switchings of the terminal n and the threshold raising order F, the hysteresis threshold raising amount ΔR(n) is determined in the form of an exponential function or a power function. When the hysteresis threshold raising amount ΔR(n) is determined in the form of an exponential function, the threshold raising order F is greater than 1, and when the hysteresis threshold raising amount ΔR(n) is determined in the form of a power function, the threshold raising order F is greater than 0 (in order to make the hysteresis threshold raising amount ΔR(n) increase faster and faster as n increases, F may be greater than 1), so as to optimize the use of the threshold raising order, so that the hysteresis threshold raising amount ΔR(n) is increasing, and ΔR(n) increases rapidly as n increases.

[0053] Among them, the exponential function form mentioned above can be specifically F n , at this time, you can use R n =R n-1 +F n Determine the hysteresis threshold R corresponding to the next cell switching of the terminal n Of course, we can also use k1×F n (k1 is the first proportionality coefficient, k1 is greater than 0) or other exponential function forms to determine the hysteresis threshold raising amount ΔR(n). The power function form mentioned above can be specifically n F , at this time, you can use R n =R n-1 +n F Determine the hysteresis threshold R corresponding to the next cell switching of the terminal n Of course, we can also use k2×n F (k2 is the second proportional coefficient, k2 is greater than 0) and so on to determine the hysteresis threshold raising amount ΔR(n).

[0054] Through the above settings, the initial hysteresis threshold increase amount can change slowly. As the total number of cell switching of the terminal gradually increases, the hysteresis threshold increase amount increases rapidly, so that the terminal can more easily find a cell with better signal strength for connection in the initial stage. At the same time, when switching occurs frequently, the hysteresis threshold increase amount will increase rapidly in an exponential form after several switchings, thereby quickly and efficiently suppressing the ping-pong effect.

[0055] Of course, the hysteresis threshold increase amount ΔR(n) can also be determined according to the total number of cell switching times n of the terminal and the threshold increase order F in the form of an integer (including a monomial and a polynomial, where the monomial can be, for example, F×n, and the polynomial can be, for example, F×n+F×(n-1)+…+F, etc.). In this integer form, the hysteresis threshold increase amount ΔR(n) increases with the increase of the total number of cell switching times n of the terminal, and the hysteresis threshold increase amount ΔR(n) is greater than 0.

[0056] A ping-pong handover suppression method provided in an embodiment of the present application, which determines a hysteresis threshold corresponding to the next cell handover of the terminal according to the hysteresis threshold corresponding to the current cell handover of the terminal, may include: The hysteresis threshold corresponding to the next cell switching of the terminal is determined according to the hysteresis threshold corresponding to the current cell switching of the terminal and the preset hysteresis threshold increase amount.

[0057] In an embodiment of the present application, the amount of increase in the hysteresis threshold each time may also be set to a fixed value, that is, the corresponding parameters pre-configured in the terminal may include a preset hysteresis threshold increase, wherein the preset hysteresis threshold increase is greater than 0 (for example, it may be 10, 20, etc.), and its specific value may be set by relevant personnel based on experience or through pre-experiments.

[0058] On the basis of the above, the hysteresis threshold corresponding to the next cell switching of the terminal can be determined according to the hysteresis threshold corresponding to the current cell switching of the terminal and the preset hysteresis threshold increase. For example, the preset hysteresis threshold increase can be added to the hysteresis threshold corresponding to the current cell switching of the terminal, or the product of a third proportional coefficient (the third proportional coefficient can be specifically greater than 1) and the preset hysteresis threshold increase can be added to the hysteresis threshold corresponding to the current cell switching of the terminal to determine the hysteresis threshold corresponding to the next cell switching of the terminal.

[0059] A ping-pong handover suppression method provided in an embodiment of the present application controls the cell handover of a terminal according to a corresponding hysteresis threshold when a cell handover occurs next time in the terminal, and may include: Determine whether the difference between the signal strength of the target cell and the signal strength of the current cell accessed by the terminal is greater than or equal to the hysteresis threshold corresponding to the next cell switching of the terminal; If so, the terminal is switched from the current cell to the target cell.

[0060] In the embodiment of the present application, the process of controlling the cell switching of the terminal according to the hysteresis threshold corresponding to the next cell switching of the terminal may specifically be: obtaining the signal strength of the current cell accessed by the terminal (that is, the cell currently accessed by the terminal), and simultaneously obtaining the signal strength of the target cell, and determining whether the difference between the signal strength of the target cell and the signal strength of the current cell accessed by the terminal (specifically, the difference obtained by subtracting the signal strength of the target cell from the signal strength of the current cell accessed by the terminal) is greater than or equal to the hysteresis threshold R corresponding to the next cell switching of the terminal. n The target cell is a neighboring cell of the current cell. When there is only one neighboring cell, the neighboring cell is the target cell. When the number of neighboring cells is greater than 1, the target cell is the neighboring cell with the largest signal strength.

[0061] If the difference between the signal strength of the target cell and the signal strength of the current cell to which the terminal is connected is less than the hysteresis threshold R corresponding to the next cell switching of the terminal n , the cell switching can be omitted, but the terminal can continue to access the current cell and continue to determine whether the difference between the signal strength of the target cell and the signal strength of the current cell to which the terminal is connected is greater than or equal to the hysteresis threshold R corresponding to the next cell switching of the terminal. n .

[0062] If the difference between the signal strength of the target cell and the signal strength of the current cell to which the terminal is connected is greater than or equal to the hysteresis threshold R corresponding to the next cell switching of the terminal n , the terminal can be switched from the current cell to the target cell. Specifically, the terminal can send a corresponding measurement report to the base station and normally switch the corresponding cell, so that the terminal switches from accessing the current cell to accessing the target cell.

[0063] A ping-pong handover suppression method provided in an embodiment of the present application may further include, before switching a terminal from a current cell to a target cell: Determine whether the duration of the hysteresis threshold corresponding to the next cell switching of the terminal is greater than the first time threshold when the difference between the signal strength of the target cell and the signal strength of the current cell is greater than or equal to the first time threshold; If so, the step of switching the terminal from the current cell to the target cell is performed.

[0064] In the embodiment of the present application, the corresponding parameters pre-configured in the terminal may include a first time threshold T s , whose specific value can be set by relevant personnel based on experience, etc. When it is determined that the difference between the signal strength of the target cell and the signal strength of the current cell accessed by the terminal is greater than or equal to the corresponding hysteresis threshold R when the terminal switches to the next cell n Afterwards, before switching the terminal from the current cell to the target cell (that is, before the terminal determines whether to send a measurement report to perform the corresponding switching process), it is also possible to obtain that the difference between the signal strength of the target cell and the signal strength of the current cell is greater than or equal to the hysteresis threshold R corresponding to the next cell switching of the terminal n duration T1, and determining whether the duration T1 is greater than the first time threshold T s .

[0065] If the duration T1 is not greater than the first time threshold T s In this case, if the difference between the signal strength of the target cell and the signal strength of the current cell to which the terminal is connected is greater than or equal to the hysteresis threshold R corresponding to the next cell switching of the terminal n, then the difference between the signal strength of the target cell and the signal strength of the current cell is greater than or equal to the hysteresis threshold R corresponding to the next cell switching of the terminal n The duration T1 is determined to determine whether the duration T1 is greater than the first time threshold T s If the difference between the signal strength of the target cell and the signal strength of the current cell to which the terminal is connected is less than the hysteresis threshold R corresponding to the next cell switching of the terminal n , then no cell switching is performed, and the system can return to the initial state, continue to monitor the signal strength of other adjacent cells, and make judgments, etc.

[0066] If the duration T1 is greater than the first time threshold T s , then execute the step of switching the terminal from the current cell to the target cell.

[0067] Through the above implementation, on the basis of raising the hysteresis threshold, corresponding restrictions are also imposed on each switching action, so that judgment is made not only from the dimension of signal strength of the target cell, but also from the dimension of duration of the signal strength of the target cell. Only when the difference between the signal strength of the target cell and the signal strength of the current cell is greater than or equal to the corresponding hysteresis threshold and the duration of this phenomenon is greater than the first time threshold, the corresponding measurement report will be sent, and then the corresponding switching process will be continued to be executed, so as to realize cell switching only when it is determined that the signal strength of the target cell is stable, and not to perform cell switching when the signal of the target cell is unstable, thereby further significantly suppressing the occurrence of ping-pong switching and improving the stability of the system.

[0068] See also Figure 3 , which shows a flow chart of another ping-pong handover suppression method provided by an embodiment of the present application. A ping-pong handover suppression method provided by an embodiment of the present application, when controlling the cell handover of the terminal according to the hysteresis threshold corresponding to the next cell handover of the terminal, may also include: If the terminal does not switch cells, determine whether the duration of the terminal accessing the current cell is greater than a second time threshold; If so, lower the hysteresis threshold corresponding to the next cell switching of the terminal, reset the duration of the terminal accessing the current cell to zero, and return to the step of determining whether the duration of the terminal accessing the current cell is greater than the second time threshold; If the terminal undergoes cell switching or the duration of the terminal accessing the current cell is not greater than the second time threshold, the process returns to the step of obtaining the hysteresis threshold corresponding to the current cell switching of the terminal.

[0069] In the embodiment of the present application, the corresponding parameters pre-configured in the terminal may include the second time threshold T a, whose specific value can be set by relevant personnel based on experience, etc. According to the hysteresis threshold R corresponding to the next handover of the terminal n When performing cell switching control on the terminal, if the terminal does not switch cells, the corresponding timer can be started to count the duration T2 of the terminal accessing the current cell in real time, and determine whether the duration T2 of the terminal accessing the current cell is greater than the second time threshold T a .

[0070] If it is determined that the duration T2 of the terminal accessing the current cell is greater than the second time threshold T a , it indicates that the current connection is in a stable state. It also indicates that the signal strength of the adjacent cell has not reached the required level under the current hysteresis threshold, but there may be a base station with a better signal level than the current one. Therefore, the hysteresis threshold can be appropriately lowered to relax the switching conditions, so as to facilitate the terminal to find a better connection base station. That is, when the duration T2 of the terminal accessing the current cell is greater than the second time threshold T a , the system can be aged accordingly so as to no longer suppress the occurrence of switching. Specifically, the hysteresis threshold corresponding to the next cell switching of the terminal can be lowered, and the lowered hysteresis threshold can be determined as the hysteresis threshold corresponding to the next switching of the terminal, so as to achieve aging of the hysteresis threshold, retain the terminal's switching capability, and enable the terminal to switch to a target cell with a better signal level. While or after lowering the hysteresis threshold corresponding to the next cell switching of the terminal, the duration of the terminal's access to the current cell is reset to zero, and then, the step of determining whether the duration of the terminal's access to the current cell is greater than the second threshold is returned to execute, so as to perform aging processing on the hysteresis threshold based on the determination result and retain the terminal's switching capability or raise the hysteresis threshold to suppress the occurrence of ping-pong switching.

[0071] If the corresponding hysteresis threshold R is set according to the next switching of the terminal n When performing cell switching control on the terminal, determining that the terminal has cell switching, or determining whether the duration T2 of the terminal accessing the current cell is greater than the second time threshold T a When determining that the duration T2 of the terminal accessing the current cell is not greater than the second time threshold T a(i.e., the terminal switches cells during this process), then the step of obtaining the hysteresis threshold corresponding to the current cell switching of the terminal can be returned, that is, the hysteresis threshold corresponding to the current cell switching of the terminal can be continued to be obtained, and the hysteresis threshold corresponding to the next cell switching of the terminal can be determined according to the hysteresis threshold corresponding to the current cell switching of the terminal, so as to raise the hysteresis threshold corresponding to the next cell switching of the terminal. After raising the corresponding hysteresis threshold, the terminal can return to the initial state, and then the cell switching of the terminal can be controlled based on the hysteresis threshold corresponding to the next cell switching of the terminal, so as to suppress the occurrence of ping-pong switching.

[0072] In the above process, after lowering the hysteresis threshold corresponding to the next cell switching of the terminal and returning the counted duration of the terminal's access to the current cell to zero, when continuing to count the duration of the terminal's access to the current cell, if the duration is less than the set second time threshold, it is considered that the terminal has undergone cell switching after the switching conditions have been relaxed and a better base station connection has been found. After the switching, the hysteresis threshold can be raised accordingly and returned to the initial state, and then it is determined whether a cell switching has occurred in the cell based on the raised hysteresis threshold.

[0073] Through the above, it can be achieved that when switching occurs, the hysteresis threshold is raised to suppress the occurrence of switching, thereby avoiding the ping-pong effect. When the connection is stable and switching no longer occurs, the hysteresis threshold is lowered to no longer suppress the occurrence of switching, so that the terminal can switch normally, so that the terminal can adapt to the actual situation of different signal strengths, so that the method of suppressing ping-pong switching is more universal. That is, all processes are a cyclic control system, which will dynamically adjust the switching hysteresis threshold according to the actual number of switching. When the external signal state is unstable, the hysteresis threshold will be raised accordingly, thereby suppressing the occurrence of ping-pong switching, so that the terminal connection is limited to a single cell. When the connection is in a stable state, the switching hysteresis threshold will be lowered, and the switching conditions will be gradually relaxed to find a better base station connection and retain the terminal's switching capability.

[0074] A ping-pong handover suppression method provided in an embodiment of the present application, which reduces a hysteresis threshold corresponding to the next cell handover of a terminal, may include: In the reverse order of the hysteresis threshold determination order, the hysteresis threshold corresponding to the next cell switching of the terminal is reduced; the hysteresis threshold determination order is the determination order of the hysteresis threshold corresponding to the cell switching of the terminal.

[0075] In an embodiment of the present application, the hysteresis threshold corresponding to the next cell switching of the terminal can be reduced in the same manner as the hysteresis threshold corresponding to the current cell switching of the terminal is used to determine the hysteresis threshold corresponding to the next cell switching of the terminal, that is, the reduction amount of the hysteresis threshold is the same as the calculated amount of the increase and the latest hysteresis threshold increase amount is preferentially subtracted to call back to the previous level, that is, when lowering the hysteresis threshold corresponding to the next cell switching of the terminal, specifically, the increase amount is subtracted from the hysteresis threshold corresponding to the next cell switching of the terminal to lower the hysteresis threshold corresponding to the next cell switching of the terminal.

[0076] That is to say, the hysteresis threshold corresponding to the next cell switching of the terminal can be lowered in the reverse order of the hysteresis threshold determination order. The hysteresis threshold determination order mentioned here is the determination order of the hysteresis threshold corresponding to the cell switching of the terminal. Specifically, the hysteresis threshold can be called back in the reverse order of the hysteresis threshold determination order to lower the hysteresis threshold corresponding to the next cell switching of the terminal. In the process of calling back the hysteresis threshold, the hysteresis threshold will be aged in turn, and the latest hysteresis threshold increase will be subtracted first, and it will be called back to the level of the previous level, and it will quickly return to the latest restriction level after the switching event occurs in the current situation. Specifically, the hysteresis threshold determination order is R0, R1, R2, ..., R n , correspondingly reducing the hysteresis threshold corresponding to the next cell switching of the terminal can be to reduce the hysteresis threshold corresponding to the next cell switching of the terminal to R n Call back to R first n-1 If it continues to decrease, the hysteresis threshold R corresponding to the next cell switching of the terminal can be n Call back to R n-2 For example: the hysteresis threshold determination order is R0, R1, R2, R3, R4, R5, then when judging whether the duration of the terminal accessing the current cell is greater than the second time threshold, if it is determined that the duration of the terminal accessing the current cell is not greater than the second time threshold, the hysteresis threshold corresponding to the next cell switching of the terminal can be first reduced from R5 to R4, and when the duration of the terminal accessing the current cell is reset to zero and the judgment of whether the duration of the terminal accessing the current cell is greater than the second time threshold is returned, if it is determined that the duration of the terminal accessing the current cell is not greater than the second time threshold, the hysteresis threshold corresponding to the next cell switching of the terminal can be reduced from R4 to R3, and in the next judgment, if it is determined that the duration of the terminal accessing the current cell is greater than the second time threshold, the hysteresis threshold R3 corresponding to the current cell switching of the terminal can be obtained, and the hysteresis threshold corresponding to the next cell switching of the terminal is determined according to the hysteresis threshold R3 corresponding to the current cell switching of the terminal.

[0077] A ping-pong handover suppression method provided in an embodiment of the present application may further include, when lowering a hysteresis threshold corresponding to the next cell handover of a terminal: Subtract 1 from the total number of cell switchings that occur at the terminal.

[0078] In an embodiment of the present application, when lowering the hysteresis threshold corresponding to the next cell switching of the terminal, the total number of cell switchings of the terminal can also be reduced by 1, so that the hysteresis threshold corresponding to the next cell switching of the terminal can be determined based on the updated total number n and the hysteresis threshold corresponding to the current cell switching of the terminal, so that the hysteresis threshold can be changed continuously, so as to both suppress the occurrence of ping-pong switching and allow the terminal to switch to a cell with a better signal level.

[0079] For example: Based on the above example, if the corresponding hysteresis threshold when the terminal switches the cell next time is reduced from R5 to R4, and then from R4 to R3, if the total number of cell switchings of the terminal is subtracted by 1, then n=3 at this time. When it is determined on this basis that the duration of the terminal's access to the current cell is not greater than the second time threshold (that is, when the terminal switches the cell during this process), n=n+1=4 can be set. At this time, it can be determined that the hysteresis threshold corresponding to the next cell switching of the terminal is R4, so that the hysteresis threshold changes from R3 to R4, rather than n=n+1=6, and the hysteresis threshold changes from R3 to R6.

[0080] A ping-pong handover suppression method provided in an embodiment of the present application may further include, after lowering a hysteresis threshold corresponding to the next cell handover of a terminal: Determine whether the reduced hysteresis threshold is less than the initial hysteresis threshold; If yes, the lowered hysteresis threshold is restored to the hysteresis threshold before the reduction, the total number of cell switchings of the terminal is determined to be 0, and the step of resetting the duration of the terminal accessing the current cell to zero is performed; If not, the step of resetting the duration of the terminal accessing the current cell to zero is performed.

[0081] In the embodiment of the present application, after lowering the corresponding hysteresis threshold when the terminal switches cells next time, it can be determined whether the lowered hysteresis threshold is smaller than the initial hysteresis threshold.

[0082] If it is determined that the lowered hysteresis threshold is less than the initial hysteresis threshold, the lowered hysteresis threshold can be restored to the hysteresis threshold before the reduction (on the basis of reducing the hysteresis threshold corresponding to the next cell switching of the terminal in the reverse order of the hysteresis threshold determination order, the hysteresis threshold before the reduction is restored to the initial hysteresis threshold), or the hysteresis threshold corresponding to the next cell switching of the terminal can be refused to be reduced, so that the lowered hysteresis threshold can be not less than the initial hysteresis threshold, thereby avoiding the ping-pong switching effect caused by the hysteresis threshold being too small. In addition, the total number of cell switchings of the terminal can be determined as 0 to avoid the total number of cell switchings of the terminal being a negative value, and then the subsequent steps can be continued, that is, the duration of the terminal accessing the current cell can be reset to zero. If it is determined that the lowered hysteresis threshold is not less than the initial hysteresis threshold, the subsequent steps can be continued, that is, the duration of the terminal accessing the current cell can be reset to zero.

[0083] In order to more clearly illustrate the above technical solution, it is assumed that there are two adjacent cells A and B. When the signal strengths of cell A and cell B are both in a stable state, and the difference between the signal strength of one cell and the signal strength of the other cell is greater than the initial hysteresis threshold R0, the terminal will actively switch to the cell with stronger signal strength and remain in this cell.

[0084] When the signal strengths of cells A and B are both unstable, assuming that the difference in signal strength between the two cells is less than the initial hysteresis threshold R0, the terminal will remain in the initial cell (i.e., the source cell) and no handover event will occur. When the difference between the signal strength of the target cell (i.e., the cell other than the source cell in cell A and cell B) and the signal strength of the source cell (the signal strength of the target cell is large, and the signal strength of the source cell is small) is greater than or equal to the initial hysteresis threshold R0, the duration of the difference between the signal strength of the target cell and the signal strength of the source cell is greater than or equal to the initial hysteresis threshold R0 is obtained by statistics. Only when the difference between the signal strength of the target cell and the signal strength of the source cell is greater than or equal to the initial hysteresis threshold R0 for a duration greater than the first time threshold T s The terminal will switch cells only when the signal strength of the cell deteriorates rapidly after the switch. If the cell signal strength deteriorates rapidly after the switch, the terminal will quickly increase the corresponding hysteresis threshold after the switch occurs several times, thereby limiting the switch and making the terminal finally stay in one of the cells. After a period of stable connection, the hysteresis threshold is aged to find a cell with a signal strength greater than the current cell and a target cell that can be stably maintained for a period of time for switching.

[0085] When the signal strength of cell A and cell B is stable and unstable respectively, the detection of the duration of the signal strength of the target cell exceeding the hysteresis threshold and the raising of the hysteresis threshold after switching in the above system will make the terminal finally stay in the cell with relatively stable signal for communication, thereby ensuring the stability of the system connection.
