Fig. 1 is a flowchart illustrating a cell handover control method according to an exemplary embodiment, where the cell handover control method is used in a terminal, as shown in fig. 1, and includes the following steps.

In step S11, the first signal parameters of the current serving cell and the first signal parameters of the N neighboring cells of the terminal are obtained through measurement.

In this embodiment, a signal of a current serving cell of the terminal may be measured to obtain a signal parameter of the current serving cell, where the signal parameter of the current serving cell obtained by measurement is referred to as a first signal parameter of the current serving cell. The signals of N adjacent cells of the terminal may also be measured to obtain the signal parameters of each adjacent cell, and the signal parameters of the adjacent cells obtained by measurement are referred to as the first signal parameters of the adjacent cells. And N is an integer greater than or equal to 1.

The terminal, which is used for measuring the neighboring cells, is notified to the terminal by the network device, which can be referred to the description in the related art, and is not described herein again.

In step S12, when the first signal parameter of the current serving cell does not satisfy the preset communication quality requirement, and the first signal parameter of the current serving cell and/or the first signal parameter of each neighboring cell does not satisfy the preset cell switching condition; and determining a target switching cell from the N adjacent cells, wherein the target switching cell is the adjacent cell with the best signal quality in the N adjacent cells.

In this embodiment, after obtaining the first signal parameter of the current serving cell and the first signal parameters of the N neighboring cells through measurement, it is determined whether the first signal parameter of the current serving cell meets the preset communication quality requirement, and when determining that the first signal parameter of the current serving cell meets the preset communication quality requirement, the serving cell of the terminal does not need to be switched, and then a measurement report is sent to the network device, where the measurement report includes the first signal parameter of the current serving cell and the first signal parameters of the N neighboring cells obtained through measurement in step S11. When the first signal parameter of the current service cell is judged not to meet the preset communication quality requirement, the service cell of the terminal is expected to be switched, and then whether the first signal parameter of the current service cell meets the preset cell switching condition or not and whether the first signal parameter of an adjacent cell exists in N adjacent cells or not is judged. If the first signal parameter of the current serving cell and the first signal parameter of at least one of the N adjacent cells both satisfy the preset cell switching condition, it indicates that the serving cell of the terminal can be switched, and then sends a measurement report to the network device. If the first signal parameter of the current serving cell and/or the first signal parameter of each neighboring cell do not satisfy the preset cell handover condition, it is described that the serving cell of the terminal cannot be handed over under the current measurement condition, and in order to avoid that the terminal resides in the serving cell with poor signal quality all the time, this embodiment determines a neighboring cell with the best signal quality from N neighboring cells, where the neighboring cell with the best signal quality is referred to as a target handover cell.

In step S13, sending a measurement report to the network device, where the measurement report includes the second signal parameter of the current serving cell and the second signal parameters of N neighboring cells, where the second signal parameter of the current serving cell and the second signal parameter of the target handover cell satisfy a preset cell handover condition; the measurement report is used for the network device to switch the service cell of the terminal to the target switching cell.

In this embodiment, after determining the target handover cell, a measurement report is sent to the network device, where the measurement report includes a signal parameter of the current serving cell and a signal parameter of each of N neighboring cells. Here, the signal parameter of the current serving cell in the measurement report transmitted in step S13 is referred to as a second signal parameter of the current serving cell, and the signal parameter of the neighboring cell in the measurement report transmitted in step S13 is referred to as a second signal parameter of the neighboring cell. Also, the second signal parameter of the current serving cell and the second signal parameter of the target handover cell among the N neighbor cells in the measurement report transmitted in step S13 satisfy the preset cell handover condition. After receiving the measurement report, the network device switches the serving cell of the terminal according to the measurement report, so that the serving cell of the terminal is switched to the target switching cell.

In summary, the cell switching control method provided in this embodiment obtains the first signal parameter of the current serving cell and the first signal parameters of the N neighboring cells of the terminal through measurement. When the first signal parameter of the current serving cell does not meet the preset communication quality requirement and the first signal parameter of the current serving cell and/or the first signal parameter of each adjacent cell does not meet the preset cell switching condition; and determining the adjacent cell with the best signal quality from the N adjacent cells as a target handover cell. Sending a measurement report to the network equipment, wherein the measurement report comprises a second signal parameter of the current serving cell and second signal parameters of N adjacent cells, and the second signal parameter of the current serving cell and the second signal parameter of the target handover cell meet a preset cell handover condition; the measurement report is used for the network device to switch the service cell of the terminal to the target switching cell. The method and the device avoid the situation that the terminal resides in the current serving cell with poor signal quality all the time, and the communication quality of the terminal is improved because the serving cell of the terminal is triggered to be switched to the adjacent cell with good signal quality.

Fig. 2 is a flowchart illustrating a cell handover control method according to another exemplary embodiment, where, as shown in fig. 2, the cell handover control method is used in a terminal and includes the following steps.

In step S21, the first signal parameters of the current serving cell and the first signal parameters of the N neighboring cells of the terminal are obtained through measurement.

In this embodiment, the specific implementation process of step S21 may refer to the relevant description in the embodiment shown in fig. 1, and is not described herein again.

In step S22, when the first signal parameter of the current serving cell does not satisfy the preset communication quality requirement, and the first signal parameter of the current serving cell and/or the first signal parameter of each neighboring cell does not satisfy the preset cell switching condition, it is determined that the terminal is currently in a moving state.

In this embodiment, when the first signal parameter of the current serving cell does not satisfy the preset communication quality requirement, and the first signal parameter of the current serving cell and/or the first signal parameter of each neighboring cell does not satisfy the preset cell switching condition, it is determined whether the terminal is currently in a moving state or a stationary state, and when it is determined that the terminal is currently in the moving state, the following steps S23 to S26 are performed. When determining that the terminal is currently in the stationary state, reference may be made to the relevant description in the embodiment shown in fig. 6, which is not described herein again.

In step S23, a target handover cell is determined from the N neighboring cells, where the target handover cell is a neighboring cell with the best signal quality among the N neighboring cells.

And after the terminal is determined to be in the moving state, determining the adjacent cell with the best signal quality from the N adjacent cells as a target handover cell.

In step S24, the position direction of the target handover cell is acquired, and a position direction indication indicating a movement toward the position direction of the target handover cell is output.

After determining the target handover cell, the present embodiment may acquire the location direction of the target handover cell. Optionally, the terminal stores in advance a correspondence between the identifier and the position of each cell, and the terminal may obtain the position of the target handover cell according to the identifier of the target handover cell, so as to determine the position direction of the target handover cell according to the position and the current position of the target handover cell. Optionally, the network device stores in advance a correspondence between the identifier and the position of each cell, and the terminal may obtain the position of the target handover cell only from the network device according to the identifier of the target handover cell, so that the position direction of the target handover cell may be determined according to the position of the target handover cell and the current position. It should be noted that the location direction of the acquisition target handover cell is not limited to this. Wherein, the position direction of the target handover cell may be a position direction of a center of the target handover cell.

After acquiring the location direction of the target handover cell, the present embodiment outputs a location direction indication to indicate to the user to move towards the location direction of the target handover cell, for example: displaying a leftward arrow on a screen of the terminal or making a leftward movement voice to instruct the user to move leftward to be closer to the target handover cell.

In step S25, after the terminal moves towards the location direction of the target handover cell, the second signal parameters of the current serving cell and the second signal parameters of the N neighboring cells are obtained through measurement.

In this embodiment, after the terminal moves towards the position direction of the target handover cell, it indicates that the terminal is closer to the target handover cell, and this embodiment may also measure a signal of the current serving cell to obtain a signal parameter of the current serving cell, where the obtained signal parameter of the current serving cell is referred to as a second signal parameter of the current serving cell; in this embodiment, signals of N neighboring cells are measured to obtain signal parameters of each neighboring cell, and the signal parameters of the neighboring cells obtained at this time are referred to as second signal parameters of the neighboring cells.

In step S26, a measurement report is sent to the network device according to the second signal parameter of the current serving cell and the second signal parameters of the N neighboring cells.

The second signal parameter of the current serving cell and the second signal parameter of the target handover cell meet a preset cell handover condition; and the measurement report is used for the network equipment to switch the service cell of the terminal into the target switching cell.

In this embodiment, a measurement report is sent to the network device according to the second signal parameter of the current serving cell and the second signal parameters of the N neighboring cells obtained through measurement, where the measurement report includes the second signal parameter of the current serving cell and the second signal parameters of the N neighboring cells obtained through measurement. The terminal moves towards the position direction of the target handover cell, and the position of the terminal is closer to the target handover cell and farther away from the current serving cell, so that the signal quality of the current serving cell measured by the terminal is poorer and poorer, and the signal quality of the target handover cell measured by the terminal is better and better, so that the second signal parameter of the current serving cell and the second signal parameter of the target handover cell in the measurement report meet the preset cell handover condition. After receiving the measurement report, the network device switches the serving cell of the terminal according to the measurement report, so that the serving cell of the terminal is switched to the target switching cell.

In summary, the cell switching control method provided in this embodiment obtains the first signal parameter of the current serving cell and the first signal parameters of the N neighboring cells of the terminal through measurement. When the first signal parameter of the current serving cell does not meet the preset communication quality requirement, and the first signal parameter of the current serving cell and/or the first signal parameter of each adjacent cell do not meet the preset cell switching condition and the terminal is in a moving state at present, determining the adjacent cell with the best signal quality from the N adjacent cells as a target switching cell, and determines the location direction of the target handover cell and indicates the location direction to the user, and after the terminal moves toward the location direction of the target handover cell, measuring the current serving cell and N adjacent cells, and then sending a measurement report to the network equipment, wherein the measurement report comprises second signal parameters of the current serving cell and second signal parameters of the N adjacent cells obtained by measurement, the second signal parameter of the current service cell and the second signal parameter of the target switching cell meet the preset cell switching condition; the measurement report is used for the network device to switch the service cell of the terminal to the target switching cell. The method comprises the steps that the terminal is prevented from always residing in a current serving cell with poor signal quality, and the communication quality of the terminal is improved as the serving cell of the terminal is triggered to be switched to an adjacent cell with good signal quality; and moreover, the user is prevented from blindly searching for better communication signals without destination, and the user experience is improved.

Fig. 3 is a flowchart illustrating a cell handover control method according to another exemplary embodiment, where, as shown in fig. 3, the cell handover control method is used in a terminal and includes the following steps.

In step S31, the first signal parameters of the current serving cell and the first signal parameters of the N neighboring cells of the terminal are obtained through measurement.

In step S32, when the first signal parameter of the current serving cell does not satisfy the preset communication quality requirement, and the first signal parameter of the current serving cell and/or the first signal parameter of each neighboring cell does not satisfy the preset cell switching condition, it is determined that the terminal is currently in a moving state.

In this embodiment, the specific implementation processes of steps S31 and S32 may refer to the related descriptions in the embodiment shown in fig. 2, and are not described herein again.

One implementation manner of determining the target handover cell from the N neighboring cells in the present embodiment includes the following steps S33-S35.

In step S33, the signal parameters of the N neighboring cells when the terminal moves to M different positions are measured and obtained, respectively.

In this embodiment, in the moving process of the terminal, the position of the terminal is in a changed state, and when the terminal is in different positions, the signal parameters of N adjacent cells at the position of the terminal can be measured and obtained. If M is 3, the embodiment may obtain signal parameters of N neighboring cells when the terminal is at 3 different positions, that is, signal parameters of 3 groups of N neighboring cells. Optionally, the terminal may also measure and obtain signal parameters of a current serving cell of the terminal at a different location.

Among them, the following are some ways of determining M different positions. The position where the first signal parameter of the current serving cell and the signal parameters of the N neighboring cells are obtained by the terminal measurement is called a first position.

In one possible implementation, the distance between two adjacent ones of the first and M positions is equal. For example: taking the first position as a starting point, and measuring signal parameters of N adjacent cells when the terminal moves to a position which is 10 meters away; the signal parameters of N neighboring cells when the terminal is at that location are measured when the terminal moves a distance of 10 meters again, and so on.

In one possible implementation, the first location and the movement time of the terminal between two adjacent ones of the M locations are the same. For example: taking a first position as a starting point, and measuring signal parameters of N adjacent cells when the terminal moves for 10 seconds at the position; the signal parameters of the N neighbouring cells at the location of the terminal are measured when the terminal has moved for 10 seconds again, and so on. Alternatively, the same moving time is K measurement periods, where K is an integer greater than or equal to 1, that is, after step S31 is executed, the signal parameters of N neighboring cells are measured at intervals of K measurement periods, and so on.

In step S34, a mean value of the signal parameters of each neighboring cell is obtained according to the first signal parameter of each neighboring cell and the signal parameters of each neighboring cell measured at M different locations.

In this embodiment, then, based on the first signal parameter of each neighboring cell obtained by measurement in step S31 and the signal parameter of each neighboring cell obtained by measurement at M different positions, a mean value of the signal parameters of each neighboring cell can be obtained. Taking one of N neighboring cells as an example, the embodiment may sum the first signal parameter of the neighboring cell and the signal parameter of the neighboring cell measured at M different positions, and then take an average value to obtain an average value of the signal parameter of the neighboring cell. Alternatively, the embodiment performs weighted averaging on the first signal parameter of the neighboring cell and the signal parameters of the neighboring cell measured at M different positions, so as to obtain the average value of the signal parameters of the neighboring cell.

In step S35, the neighboring cell with the largest signal parameter mean is determined as the target handover cell.

In this embodiment, the signal parameter mean values of the neighboring cells are compared to determine the largest signal parameter mean value, the neighboring cell to which the largest signal parameter mean value belongs is the neighboring cell with the best signal quality, and then the neighboring cell is determined to be the target handover cell.

In step S36, the position direction of the target handover cell is acquired, and a position direction indication indicating a movement toward the position direction of the target handover cell is output.

In step S37, after the terminal moves towards the location direction of the target handover cell, the second signal parameters of the current serving cell and the second signal parameters of the N neighboring cells are obtained through measurement.

In step S38, a measurement report is sent to the network device according to the second signal parameter of the current serving cell and the second signal parameters of the N neighboring cells.

In this embodiment, the specific implementation process of steps S36-S38 may refer to the related description in the embodiment shown in fig. 2, and is not described herein again.

In summary, the cell switching control method provided in this embodiment avoids that the terminal resides in the current serving cell with poor signal quality all the time through the above-mentioned scheme, and improves the communication quality of the terminal because the serving cell of the terminal is triggered to be switched to the neighboring cell with good signal quality; and moreover, the user is prevented from blindly searching for better communication signals without destination, and the user experience is improved.

Fig. 4 is a flowchart illustrating a cell handover control method according to another exemplary embodiment, where, as shown in fig. 4, the cell handover control method is used in a terminal and includes the following steps.

In step S40, the first signal parameters of the current serving cell and the first signal parameters of N neighboring cells of the terminal are obtained at the first position measurement.

Wherein the first position is a position where the terminal is located when step S40 is performed.

In step S41, when the first signal parameter of the current serving cell does not satisfy the preset communication quality requirement, and the first signal parameter of the current serving cell and/or the first signal parameter of each neighboring cell does not satisfy the preset cell switching condition, it is determined that the terminal is currently in a moving state.

In step S42, a target handover cell is determined from the N neighboring cells, where the target handover cell is a neighboring cell with the best signal quality among the N neighboring cells.

In this embodiment, the specific implementation process of steps S40-S42 may refer to the related description in the embodiment shown in fig. 2 or fig. 3, and is not described herein again.

In step S43, a first difference between the signal parameter of the target handover cell measured by the terminal at the third location and the signal parameter of the target handover cell measured by the terminal at the second location is obtained.

In step S44, a second difference between the signal parameter of the target handover cell and the first signal parameter of the target handover cell, which is obtained by the terminal at the second location measurement, is obtained.

In this embodiment, when the terminal moves from the first location to the second location, the signal parameter of the target handover cell may be obtained through measurement, and when the second location moves to the third location, the signal parameter of the target handover cell may be obtained through measurement.

If the signal parameter of the target handover cell measured by the terminal at the first location is Q1, the signal parameter of the target handover cell measured at the second location is Q2, and the signal parameter of the target handover cell measured at the third location is Q3. The difference between Q3 and Q2 was taken as the first difference and the difference between Q2 and Q1 was taken as the second difference.

In step S45, taking the first distance in the direction of the third position and the second distance in the direction of the first position, respectively, with the second position as the starting point; the ratio of the first distance to the second distance is equal to the ratio of the first difference to the second difference.

In step S46, the position direction of the intersection of the perpendicular bisector of the first distance and the perpendicular bisector of the second distance is determined to be the position direction of the target handover cell.

In this embodiment, as shown in fig. 5, the first position is a point a, the second position is a point B, the third position is a point C, the point B is taken as a starting point, a first distance is taken along the direction BC according to the first difference, and an end point of the first distance is C'; and taking a second distance along the direction of BA according to the second difference, wherein the end point of the second distance is A'. Wherein the ratio of the first difference to the second difference is equal to the ratio of the first distance to the second distance. And then determining the perpendicular bisector of BC 'as X and the perpendicular bisector of BA' as Y, wherein the perpendicular bisector X and the perpendicular bisector Y are intersected at a point O, the position of the point O is the central position of the target handover cell, and the position direction of the point O is the position direction of the target handover cell.

It should be noted that the first position, the second position, and the third position cannot be located on the same straight line, and the first position, the second position, and the third position may form a triangle.

In step S47, a position direction instruction for instructing a movement in a position direction of the target handover cell is output.

In step S48, after the terminal moves towards the location direction of the target handover cell, the second signal parameters of the current serving cell and the second signal parameters of the N neighboring cells are obtained through measurement.

In step S49, the measurement report is sent to the network device according to the second signal parameter of the current serving cell and the second signal parameters of the N neighboring cells.

For specific implementation processes of steps S47-S49, reference may be made to the related description of the embodiment shown in fig. 2, and details are not repeated here.

Fig. 6 is a flowchart illustrating a cell handover control method according to another exemplary embodiment, where, as shown in fig. 6, the cell handover control method is used in a terminal and includes the following steps.

In step S61, the first signal parameters of the current serving cell and the first signal parameters of the N neighboring cells of the terminal are obtained through measurement.

In this embodiment, the specific implementation process of step S61 may refer to the relevant description in the embodiment shown in fig. 1, and is not described herein again.

In step S62, when the first signal parameter of the current serving cell does not satisfy the preset communication quality requirement, and the first signal parameter of the current serving cell and/or the first signal parameter of each neighboring cell does not satisfy the preset cell switching condition, it is determined that the terminal is currently in a stationary state.

In this embodiment, when the first signal parameter of the current serving cell does not satisfy the preset communication quality requirement, and the first signal parameter of the current serving cell and/or the first signal parameter of each neighboring cell does not satisfy the preset cell switching condition, it is determined whether the terminal is currently in a moving state or a stationary state, and when it is determined that the terminal is currently in the stationary state, the following steps S63 to S66 are performed. When it is determined that the terminal is currently in the moving state, reference may be made to the relevant description in the embodiments shown in fig. 2 to fig. 4, which is not described herein again.

In step S63, the neighboring cell with the best signal quality is determined as the target handover cell according to the first signal parameters of the N neighboring cells.

In this embodiment, when it is determined that the terminal is in the stationary state, the signal parameters of each neighboring cell obtained by the terminal through measurement each time may be the same, and therefore, according to the first signal parameters of the N neighboring cells obtained through measurement in step S61, the neighboring cell with the best signal quality may be determined as the target handover cell.

In step S64, setting the signal parameter of the target handover cell as the second signal parameter of the target handover cell according to the first signal parameter of the target handover cell; when the first signal parameter of the target handover cell meets the preset cell handover condition, the second signal parameter of the target handover cell is the first signal parameter of the target handover cell.

In step S65, the signal parameter of the current serving cell is set as the second signal parameter of the current serving cell according to the first signal parameter of the current serving cell, where the second signal parameter of the current serving cell is the first signal parameter of the current serving cell when the first signal parameter of the current serving cell satisfies the preset cell handover condition.

It should be noted that the execution sequence of step S64 and step S65 is not sequential.

In step S66, according to the signal parameter of the current serving cell and the signal parameter of the target handover cell, reporting the measurement to the network device; and the second signal parameters of N-1 adjacent cells except the target switching cell in the N adjacent cells are the same as the first signal parameters of the N-1 adjacent cells.

If the first signal parameter of the current serving cell meets the preset cell switching condition and the first signal parameter of the target switching cell does not meet the preset cell switching condition, setting the signal parameter of the target switching cell as the second signal parameter of the target switching cell instead of the first signal parameter of the target switching cell, and setting the signal parameter of the current serving cell as the second signal parameter of the current serving cell except that the second signal parameter of the current serving cell is equal to the first signal parameter of the current serving cell. And then sending a measurement report to the network device, wherein the signal parameter of the current serving cell included in the measurement report is a second signal parameter (namely, a first signal parameter) of the current serving cell, and the signal parameter of the target handover cell included in the measurement report is a second signal parameter (not the first signal parameter) of the target handover cell.

If the first signal parameter of the current serving cell does not meet the preset cell switching condition and the first signal parameter of the target switching cell meets the preset cell switching condition, setting the signal parameter of the current serving cell as the second signal parameter of the current serving cell instead of the first signal parameter of the current serving cell, and setting the signal parameter of the target switching cell as the second signal parameter of the target switching cell except that the second signal parameter of the target switching cell is equal to the first signal parameter of the target switching cell.
