The technical solution of the present invention will be described in detail with reference to specific embodiments from the perspective of terminal equipment.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a cell switching control method according to an embodiment of the present invention; as shown in fig. 2, the cell switching control method may include:
201. and the terminal equipment selects a target cell from all the measured cells, wherein the target cell is the cell with the strongest signal or the highest priority in all the measured cells.
After RRC connection is established between the terminal equipment and the network equipment, the terminal equipment receives measurement information sent by the network equipment, the measurement information comprises measurement frequency points and cells corresponding to the frequency points, the terminal equipment performs cell measurement according to the measurement information to obtain measurement results, the measurement results comprise communication quality, signal strength and the like, and a target cell is selected from all measured cells based on the measurement results.
202. When the network of the target cell is normal, the terminal device accesses the target cell, adjusts the network switching strategy and adjusts the reported measurement result so as to preferentially select the target cell during cell switching.
Optionally, adjusting the network policy at least includes:
the method may further include reducing a measurement threshold of the cells other than the target cell and/or adjusting a priority of the cells other than the target cell to be lower than or equal to a priority of the target cell.
Specifically, the measurement threshold of other cells may be reduced, for example, the cell may be measured when it is originally the measurement threshold of-100 dBm, but the measurement is started after the measurement threshold is changed to-105 dBm, so that, after the measurement threshold is reduced, if the terminal device is stored in a relatively static state, signal fluctuation is small, signal fluctuation of other cells is also small, and thus the corresponding measurement threshold is not satisfied, the terminal device will not measure other cells, and the number of measurements may be reduced, thereby reducing the number of reporting of measurement results. And simultaneously adjusting the priority of other cells to be the same as that of the target cell, and after the adjustment, the priority of other cells is not higher than that of the target cell (namely the priority of other cells is less than or equal to that of the target cell), so that the target cell is also preferentially selected.
Optionally, adjusting the reported measurement result at least includes:
reducing the measurement threshold of the cells other than the target cell, and/or modifying the measured communication quality of all cells, and/or modifying the measured signal strength of all cells.
Optionally, the signal strength may include at least one of:
reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), Received Signal Strength Indication (RSSI), and Signal-to-Noise Ratio (SNR).
The network device judges whether other cells meet the switching condition according to the measurement result reported by the terminal device, so that if the cell with the strongest access signal or the cell with the highest priority is selected, the measurement signal values of other cells can be properly reduced, for example, the signal value of other measured cells is reduced from-100 dBm to-108 dBm, after the terminal device reports to the network device, the network device considers that-108 dBm does not meet the switching condition, the terminal device is not instructed to switch, and the target cell is kept accessed, so that the switching times are reduced, the purpose of saving the power consumption of the terminal device is achieved, and the RRC link connection between the terminal device and the network device is not required to be maintained for a long time, and the wireless resource waste is not caused.
When the embodiment is implemented, the terminal equipment selects a target cell from all measured cells, the target cell is the cell with the strongest signal or the highest priority in all the measured cells, when the network of the target cell is normal, the target cell is accessed, and then the target cell can be preferentially selected during cell switching by adjusting the network switching measurement and adjusting the reported measurement result; therefore, the invention can select the target cell to access, and ensures that the target cell is preferentially selected by switching the cell by combining with the adjustment of the network switching strategy and the adjustment of the reported measurement result, so as to reduce the frequent switching and RRC connection time of the cell and further achieve the purpose of saving the power consumption of the terminal equipment.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating a cell switching control method according to a second embodiment of the present invention; as shown in fig. 3, the cell switching control method may include:
301. and the terminal equipment detects the reporting times of the cell measurement results and the cell switching times in a preset time period in the RRC connection state.
It can be understood that, in the RRC connected state, the network device may instruct the terminal device to measure one or more cells before performing cell handover in the same network type, and therefore, the terminal device may start measurement of the co-frequency cell or the inter-frequency cell after the signal of the current serving cell reaches the measurement threshold. And the base station judges whether the switching condition is met or not according to the measurement result reported by the terminal equipment, and if the switching condition is met, the base station instructs the terminal equipment to carry out cell switching. Therefore, it is necessary to determine whether the measurement result is reported frequently and the cell switching is frequent in the RRC connected state, and if the reporting number and the cell switching number are large in the preset time period, the measurement result is reported frequently and the cell switching is frequent.
Optionally, in the embodiment of the present invention, a timer, a first counter, and a second counter are set, and when a terminal device establishes an RRC connection and performs a first cell measurement in an RRC connection state, timing is started, where if a measurement result is reported, the first counter adds 1 to a current count, if a cell handover is performed, the second counter adds 1 to the current count, and if a timing duration of the timer matches a duration of a preset time period, a current count of the first counter is obtained as a reporting number of cell measurement results and a current count of the second counter is obtained as a cell handover number.
302. If the reporting times meet a first threshold and/or the cell switching times meet a second threshold, whether the moving distance of the user in a preset time period is within a first preset range or whether the signal fluctuation range of the serving cell is within a second preset range is judged. When the moving distance of the user is within a first preset range or the signal fluctuation range of the serving cell is within a second preset range within a preset time period, the process goes to step 303 and step 306, otherwise, the process goes to step 301.
If the number of reporting the measurement result in the preset time period satisfies the first threshold, it indicates that the measurement result is reported frequently, and the number of cell switching times in the preset time period satisfies the second threshold, it indicates that the cell switching is frequent. Meanwhile, in order to avoid that the cell switching caused by the movement of the user is identified as an abnormal switching scene, in the embodiment of the present invention, the movement condition of the user can be further determined by judging the movement of the user, specifically, according to the movement distance or signal fluctuation of the user.
Further optionally, the determining whether the moving distance of the user within the preset time period is within the first preset range includes: the method comprises the steps of obtaining motion data in a preset time period through a motion sensor arranged in the terminal device, determining the moving distance of a user according to the motion data, and finally judging whether the moving distance is within a first preset range. Through the implementation mode, the motion data can be quickly acquired by using the motion sensor built in the terminal equipment, and the motion condition of the user can be determined.
The first preset range may be set by the terminal device according to experience or manually by a user.
Or, further optionally, whether the signal fluctuation range of the serving cell is within the second preset range may include: and continuously acquiring a plurality of signals of the same serving cell within a preset time period, and judging whether the signal fluctuation of the serving cell is within a second preset range according to the acquired signals. For example, if the signal fluctuation of the same serving cell is less than 5dBm, then the terminal device may be considered to be moving less or not.
303. The cell with the strongest signal is selected from all the cells measured.
304. When the network of the cell with the strongest signal is normal, the cell is accessed.
It can be understood that, when it is determined that the cell handover is frequent and the user does not move through step 301 and step 302, the terminal device may be considered to be in an abnormal handover scenario, in which the terminal device may preferentially select a cell with the strongest signal from all measured cells, and when it is determined that the cell network can also be used normally, access the cell to stop the cell frequent handover.
Specifically, after the abnormal handover scenario is detected, the terminal device preferentially selects the cell with the strongest signal, performs verification to test whether the network is normal, for example, confirms whether the network is normal through a domain name or domain names of PING, and if the cell with the strongest signal is normal, selects to access the cell and starts to adjust the handover strategy.
305. And adjusting the network switching strategy.
Optionally, adjusting the network policy at least includes:
the method may further include reducing a measurement threshold of the cells other than the target cell and/or adjusting a priority of the cells other than the target cell to be lower than or equal to a priority of the target cell.
Specifically, the measurement threshold of other cells may be reduced, for example, the cell may be measured when it is originally the measurement threshold of-100 dBm, but the measurement is started after the measurement threshold is changed to-105 dBm, so that, after the measurement threshold is reduced, if the terminal device is stored in a relatively static state, signal fluctuation is small, signal fluctuation of other cells is also small, and thus the corresponding measurement threshold is not satisfied, the terminal device will not measure other cells, and the number of measurements may be reduced, thereby reducing the number of reporting of measurement results. And simultaneously adjusting the priority of other cells to be the same as that of the target cell, and after the adjustment, the priority of other cells is not higher than that of the target cell (namely the priority of other cells is less than or equal to that of the target cell), so that the target cell is also preferentially selected.
306. And adjusting the reported measurement result.
Reducing the measurement threshold of the cells other than the target cell, and/or modifying the measured communication quality of all cells, and/or modifying the measured signal strength of all cells.
The network device judges whether other cells meet the switching condition according to the measurement result reported by the terminal device, so that if the cell with the strongest access signal or the cell with the highest priority is selected, the measurement signal values of other cells can be properly reduced, for example, the signal value of other measured cells is reduced from-100 dBm to-108 dBm, after the terminal device reports to the network device, the network device considers that-108 dBm does not meet the switching condition, the terminal device is not instructed to switch, and the target cell is kept accessed, so that the switching times are reduced, the purpose of saving the power consumption of the terminal device is achieved, and the RRC link connection between the terminal device and the network device is not required to be maintained for a long time, and the wireless resource waste is not caused.
307. And when the cell network with the strongest signal is abnormal, detecting whether the cell network with the highest priority in all the measured cells is normal.
If the cell network with the strongest signal can not be used normally, the cell with the highest priority is selected from all the measured cells, and if the cell network can be used normally, the cell can be accessed.
308. And accessing the cell with the highest priority.
After step 308, step 305 and step 306 are executed.
Therefore, by implementing the embodiment of the invention, the cell which has the strongest signal and can be normally used by the network is selected to be accessed, and the cell is ensured to be switched and preferentially selected in the cell by combining the adjustment of the network switching strategy and the adjustment of the reported measurement result, so that the frequent switching time and the RRC connection time of the cell are reduced, and the purpose of saving the power consumption of the terminal equipment is achieved; and when the cell network with the strongest signal can not be used normally, selecting the cell with the highest priority, if the cell network is used normally, accessing the cell, and then adjusting the network switching strategy and adjusting the reported measurement result to ensure that the cell is switched and selected preferentially in the cell so as to reduce the time for frequently switching the cell and RRC connection, thereby achieving the purpose of saving the power consumption of the terminal equipment.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a cell switching control apparatus according to an embodiment of the present invention; as shown in fig. 4, the cell switching control device may include:
a selecting module 410, configured to select a target cell from all the measured cells, where the target cell is a cell with a strongest signal or a highest priority among all the measured cells;

the adjusting module 430 is configured to adjust the network handover policy and adjust the reported measurement result when the network of the target cell is normal, so as to preferentially select the target cell during cell handover.
Optionally, the manner of adjusting the network handover policy by the adjusting module 430 specifically includes:
the method may further include reducing a measurement threshold of the cells other than the target cell and/or adjusting a priority of the cells other than the target cell to be lower than or equal to a priority of the target cell.
Specifically, the measurement threshold of other cells may be reduced, for example, the measurement may be performed only when the cell is originally a measurement threshold of-100 dBm, but the measurement is started after the measurement threshold is reduced to-105 dBm, so that after the measurement threshold is reduced, if the terminal device is stored in a relatively static state, signal fluctuation is small, signal fluctuation of other cells is also small, and thus the corresponding measurement threshold is not met, the terminal device may not measure other cells, and the number of measurements may be reduced, thereby reducing the number of times of reporting the measurement result. And simultaneously adjusting the priority of other cells to be the same as that of the target cell, and after the adjustment, the priority of other cells is not higher than that of the target cell (namely the priority of other cells is less than or equal to that of the target cell), so that the target cell is also preferentially selected.
Further optionally, the manner for adjusting the reported measurement result by the adjusting module 430 specifically includes:
reducing the measurement threshold of the cells other than the target cell, and/or modifying the measured communication quality of all cells, and/or modifying the measured signal strength of all cells.
Because the network device judges whether other cells meet the switching condition according to the measurement result reported by the terminal device, if the cell with the strongest access signal or the cell with the highest priority has been selected, the measurement signal value of other cells can be properly reduced, for example, the signal value of other measured cells is reduced from-100 dBm to-108 dBm, after the terminal device reports to the network device, the network device considers that-108 dBm does not meet the switching condition, and the terminal device is not instructed to switch, so that the target cell is kept accessed, the switching times are reduced, the power consumption of the terminal device is saved, and the RRC link connection is not maintained between the terminal device and the network device for a long time, and the wireless resource waste is not caused.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a cell switching control apparatus according to a second embodiment of the present invention; the cell switching control apparatus shown in fig. 5 is optimized based on the cell switching control apparatus shown in fig. 4, and the cell switching control apparatus shown in fig. 5 further includes:
a detecting module 510, configured to detect, in a radio resource control RRC connected state, the number of times of reporting a cell measurement result and the number of times of cell handover in a preset time period before the selecting module 410 selects a target cell from all measured cells;
the selecting module 410 is configured to trigger execution of selection of a target cell from all measured cells if the number of reporting times meets a first threshold and/or the number of cell switching times meets a second threshold.
Further optionally, the selecting module 410 is configured to trigger execution of selection of a target cell from all measured cells if the number of times of reporting meets a first threshold and/or the number of times of cell switching meets a second threshold, and the moving distance of the user is within a first preset range or the signal fluctuation range of the serving cell is within a second preset range in a preset time period.
By implementing the embodiment, the frequent cell switching and RRC connection time are reduced, so that the aim of saving the power consumption of the terminal equipment is fulfilled, and the waste of radio resources is reduced.
