The embodiment of the invention discloses a cell switching control method, a cell switching control device and terminal equipment, which can reduce frequent cell switching and RRC (radio resource control) connection time, thereby achieving the purpose of saving power consumption of the terminal equipment. The technical scheme of the invention will be described in detail below with reference to specific embodiments from the point of view of terminal equipment.
Referring to fig. 2, fig. 2 is a flow chart of a cell handover control method according to an embodiment of the present invention; as shown in fig. 2, the cell handover control method may include:
201. the terminal equipment selects a target cell from all the measured cells, wherein the target cell is the cell with the strongest signal or highest priority in all the measured cells.
After the terminal device establishes the RRC connection with the network device, measurement information sent by the network device is received, where the measurement information includes measurement frequency points, where the frequency points correspond to cells, and the terminal device performs cell measurement according to the measurement information to obtain a measurement result, where the measurement result includes communication quality, signal strength, and the like, and based on the measurement result, in the embodiment of the present invention, a target cell is selected from all measured cells.
202. And when the network of the target cell is normal, the terminal equipment accesses the target cell, adjusts a 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:
reducing the measurement threshold of cells other than the target cell and/or adjusting the priority of cells other than the target cell to be lower than or equal to the priority of the target cell.
Specifically, the measurement threshold of other cells can be reduced, for example, the measurement threshold of the cell is originally-100 dBm, but the measurement threshold is changed to be-105 dBm, and then the measurement is started, so that after the measurement threshold is reduced, if the terminal equipment is stored in a static state, the signal fluctuation is smaller, and therefore, the signal fluctuation of other cells is smaller, the corresponding measurement threshold is not met, the terminal equipment can not measure other cells, the measurement times can be reduced, and the reporting times of the measurement results are further reduced. And the priority of other cells is adjusted to be the same as that of the target cell, and the priority of other cells is not higher than that of the target cell after adjustment (i.e. the priority of other cells is less than or equal to that of the target cell), then the target cell is also selected preferentially.
Optionally, adjusting the reported measurement result may at least include:
reducing measurement thresholds of cells other than the target cell, and/or modifying communication quality of all cells measured, and/or modifying signal strength of all cells measured.
Optionally, the signal strength may include at least one of:
reference Signal received power (Reference Signal Receiving Power, RSRP), reference Signal received quality (Reference Signal Receiving Quality, RSRQ), signal to interference plus Noise Ratio (Signal to Interference plus Noise Ratio, SINR), received Signal strength indication (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 if the cell with the strongest access signal or the cell with the highest priority is selected, the measurement signal value of the other cells can be properly reduced, for example, the measured signal value of the other 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, thereby the access target cell is kept, the switching times are reduced, the purpose of saving the power consumption of the terminal device is achieved, and the RRC link connection is not maintained between the terminal device and the network device for a long time, so that the wireless resource waste is avoided.
The embodiment is implemented, the terminal device selects the target cell from all the measured cells, the target cell is the cell with the strongest signal or highest priority among 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 network switching measurement and adjusting reported measurement results; therefore, the invention can select the target cell for access, and combine with the adjustment of the network switching strategy and the adjustment of the reported measurement result to ensure that the target cell is preferentially selected in the cell switching, thereby reducing the frequent cell switching and the RRC connection time and further achieving the purpose of saving the power consumption of the terminal equipment.
Referring to fig. 3, fig. 3 is a flow chart of a cell handover control method according to a second embodiment of the present invention; as shown in fig. 3, the cell handover control method may include:
301. the terminal equipment detects the reporting times of the cell measurement results in a preset time period and the cell switching times in the RRC connection state.
It can be understood that, in the RRC connected state, the network device instructs the terminal device to measure one or more cells before cell handover in the same network system, so that the terminal device starts measurement of the same-frequency cell or different-frequency cell after the current serving cell signal 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 so, the base station instructs the terminal equipment to perform cell switching. Therefore, it is required to determine whether the measurement result is frequently reported and the cell is frequently switched in the RRC connected state, and if the number of reporting times and the number of cell switching times are more in the preset period of time, it is indicated that the measurement result is frequently reported and the cell is frequently switched.
Optionally, in the embodiment of the present invention, a timer, a first counter and a second counter are set, when the terminal device establishes RRC connection and performs first cell measurement in the RRC connection state, the first counter adds 1 to the current count if the measurement result is reported, the second counter adds 1 to the current count if the cell is switched, and if the timing duration of the timer matches the duration of the preset time period, the current count of the first counter is obtained as the reporting number of the cell measurement result and the current count of the second counter is obtained as the cell switching number.
302. If the reporting times meet the first threshold value and/or the cell switching times meet the second threshold value, judging whether the moving distance of the user in the preset time period is within a first preset range or whether the signal fluctuation range of the service cell is within a second preset range. And when the moving distance of the user in the preset time period is in the first preset range or the signal fluctuation range of the serving cell is in the second preset range, turning to the steps 303-306, otherwise turning to the step 301.
If the number of times of reporting the measurement result in the preset time period meets the first threshold, the measurement result is reported frequently, and the number of times of switching the cell in the preset time period meets the second threshold, the cell is switched frequently, and of course, the RRC is connected for a long time regardless of whether the reporting or the switching is frequent, so that the radio resource waste and the power consumption are caused. Meanwhile, in order to avoid that cell switching caused by movement of a user is identified as an abnormal switching scene, in the embodiment of the invention, the movement condition of the user can be determined according to the movement distance or signal fluctuation of the user by further judging the movement of the user.
Further optionally, determining whether the movement distance of the user within the preset time period is within the first preset range includes: and acquiring motion data in a preset time period through a motion sensor built in the terminal equipment, determining the moving distance of the user according to the motion data, and finally judging whether the moving distance is in a first preset range. According to the embodiment, the motion data can be quickly acquired by utilizing the motion sensor built in the terminal equipment, and the motion condition of the user can be determined.
The above-mentioned first preset range may be set empirically by the terminal device or manually by the 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 in a preset time period, and judging whether the signal fluctuation of the serving cell is in a second preset range or not according to the acquired plurality of signals. For example, when the same serving cell signal fluctuates by less than 5dBm, then the terminal device may be considered to move less or not.
303. The cell with the strongest signal is selected from all the cells measured.
304. And accessing the cell when the cell network with the strongest signal is normal.
It will be appreciated that when it is determined that the cell handover is frequent and the user is not moving, via steps 301-302, the terminal device may be considered to be in an abnormal handover scenario, where the terminal device may preferentially select a cell with the strongest signal from all the measured cells, and access the cell to stop the cell frequent handover when it is determined that the cell network is also normally used.
Specifically, after the abnormal switching scenario is detected, the terminal device preferentially selects the cell with the strongest signal, and performs verification to test whether the network is normal, for example, whether the network is normal is confirmed by a certain domain name or a plurality of domain names of PING, if the cell with the strongest signal is normal, the terminal device selects to access the cell, and starts to adjust the switching strategy.
305. And adjusting a network switching strategy.
Optionally, adjusting the network policy at least includes:
reducing the measurement threshold of cells other than the target cell and/or adjusting the priority of cells other than the target cell to be lower than or equal to the priority of the target cell.
Specifically, the measurement threshold of other cells can be reduced, for example, the measurement threshold of the cell is originally-100 dBm, but the measurement threshold is changed to be-105 dBm, and then the measurement is started, so that after the measurement threshold is reduced, if the terminal equipment is stored in a static state, the signal fluctuation is smaller, and therefore, the signal fluctuation of other cells is smaller, the corresponding measurement threshold is not met, the terminal equipment can not measure other cells, the measurement times can be reduced, and the reporting times of the measurement results are further reduced. And the priority of other cells is adjusted to be the same as that of the target cell, and the priority of other cells is not higher than that of the target cell after adjustment (i.e. the priority of other cells is less than or equal to that of the target cell), then the target cell is also selected preferentially.
306. And adjusting the reported measurement result.
Reducing measurement thresholds of cells other than the target cell, and/or modifying communication quality of all cells measured, and/or modifying signal strength of all cells measured.
The network device judges whether other cells meet the switching condition according to the measurement result reported by the terminal device, so if the cell with the strongest access signal or the cell with the highest priority is selected, the measurement signal value of the other cells can be properly reduced, for example, the measured signal value of the other 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, thereby the access target cell is kept, the switching times are reduced, the purpose of saving the power consumption of the terminal device is achieved, and the RRC link connection is not maintained between the terminal device and the network device for a long time, so that the wireless resource waste is avoided.
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 cannot be used normally, selecting the cell with the highest priority from all the measured cells, and if the cell network can be used normally, accessing the cell.
308. And accessing the cell with the highest priority.
After step 308 is performed, steps 305-306 are performed.
Therefore, by implementing the embodiment of the invention, firstly, the cell with the strongest signal and normal network use is selected, and then the cell is preferentially selected in the cell switching 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, thereby achieving the purpose of saving the power consumption of the terminal equipment; and when the cell network with the strongest signal cannot be normally used, selecting the cell with the highest priority, if the cell network is normally used, accessing the cell, then adjusting the network switching strategy and the reported measurement result to ensure that the cell is preferentially selected in the cell switching, so as to reduce the frequent switching and RRC connection time of the cell, 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 handover control device according to an embodiment of the present invention; as shown in fig. 4, the cell handover control apparatus may include:
a selecting module 410, configured to select a target cell from all measured cells, where the target cell is a cell with the strongest signal or highest priority among all measured cells;
an access module 420, configured to access the target cell when the target cell network is normal; and
and the adjusting module 430 is configured to adjust the network switching policy and adjust the reported measurement result to preferentially select the target cell when the cell is switched when the target cell network is normal.
Optionally, the manner in which the adjustment module 430 is configured to adjust the network switching policy is specifically:
reducing the measurement threshold of cells other than the target cell and/or adjusting the priority of cells other than the target cell to be lower than or equal to the priority of the target cell.
Specifically, the measurement threshold of other cells can be reduced, for example, the measurement threshold of the cell is originally-100 dBm, but the measurement threshold is changed to be-105 dBm, and then the measurement is started, so that after the measurement threshold is reduced, if the terminal equipment is stored in a static state, the signal fluctuation is smaller, and therefore, the signal fluctuation of other cells is smaller, the corresponding measurement threshold is not met, the terminal equipment can not measure other cells, the measurement times can be reduced, and the reporting times of the measurement results are further reduced. And the priority of other cells is adjusted to be the same as that of the target cell, and the priority of other cells is not higher than that of the target cell after adjustment (i.e. the priority of other cells is less than or equal to that of the target cell), then the target cell is also selected preferentially.
Further optionally, the manner in which the adjustment module 430 is configured to adjust the reported measurement result is specifically:
reducing measurement thresholds of cells other than the target cell, and/or modifying communication quality of all cells measured, and/or modifying signal strength of all cells measured.
Because the network device judges whether other cells meet the switching condition through the measurement result reported by the terminal device, if the cell with the strongest access signal or the cell with the highest priority is selected, the measurement signal value of the other cells can be properly reduced, for example, the measured signal value of the other 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, thereby the access target cell is kept, the switching times are reduced, the purpose of saving the power consumption of the terminal device is achieved, and the RRC link connection is not maintained between the terminal device and the network device for a long time, so that the wireless resource waste is avoided.

a detecting module 510, configured to detect, in a radio resource control RRC connected state, the number of times of reporting and the number of times of cell handover of a cell measurement result in a preset period of time before the selecting module 410 selects a target cell from all the measured cells;
