step 101: and when the terminal is determined to be in a standby state and the terminal is in an idle state, measuring the signal quality of the current service cell of the terminal to obtain a signal quality measurement index.
Here, the standby state refers to a state in which the terminal is powered on but does not perform any substantial work (e.g., does not operate on files and programs), i.e., the terminal is not used. Illustratively, in some embodiments, the determining that the terminal is in a standby state includes: identifying whether the terminal is static or not through a sensor built in the terminal; acquiring the screen-off duration of the terminal, and determining whether the screen-off duration exceeds a preset duration; and determining that the terminal is static, and determining that the screen-off duration exceeds the preset duration that the terminal is in a standby state.
The example terminal is in a static state and the screen-off duration exceeds the preset duration, and the terminal is determined to be in a standby state. For example, the preset time period may be set to 20 minutes.
For example, the sensor built in the terminal is an acceleration sensor, the acceleration sensor is used for measuring the acceleration of the terminal, the acceleration sensor outputs signals when the terminal moves in any direction, and the acceleration sensor does not output signals when the terminal is stationary, so that whether the terminal is stationary can be determined according to whether the acceleration sensor outputs signals. Or the sensor built in the terminal is a gyroscope sensor, the gyroscope sensor is used for measuring the rotation angle of the terminal, and when the rotation angle of the terminal is not changed, the terminal is determined to be static.
Here, the idle state refers to no information interaction between the terminal and the base station.
Here, the serving cell refers to a cell in which the terminal currently resides.
Here, the signal quality metric of the current serving cell includes at least one of: reference Signal Received Power (RSRP) and Signal to Noise Ratio (SINR). Wherein Reference Signal received power, RSRP, refers to the linear average in frequency space over the power component of those resource elements that carry Cell-specific Reference signals (CRS) within the considered measurement frequency bandwidth. The signal-to-noise ratio SINR refers to the ratio of the strength of the received useful signal to the strength of the received interfering signal (noise and interference).

In some embodiments, the residence conditions include: the reference signal receiving power is greater than a preset receiving power, and/or the signal-to-noise ratio is greater than a preset signal-to-noise ratio.
Here, the preset received power refers to a minimum reference signal received power for measuring a cell signal quality. The preset signal-to-noise ratio refers to the minimum signal-to-noise ratio for measuring the signal quality of the cell.
Illustratively, the predetermined received power may be-90 dBm and the predetermined signal-to-noise ratio may be 3 dB. Here, when the signal quality metric includes reference signal received power RSRP, and the reference signal received power RSRP is greater than-90 dBm, it is determined that the signal quality of the current serving cell is good, that is, it is determined that the current serving cell satisfies the camping condition. And when the signal quality measurement index comprises a signal to noise ratio SINR (signal to noise ratio), and the signal to noise ratio SINR is more than 3dB, determining that the signal quality of the current service cell is good, namely determining that the current service cell meets the residence condition. And when the signal quality measurement indexes comprise reference signal received power RSRP and signal to noise ratio SINR, and the reference signal received power RSRP is larger than-90 dBm and the signal to noise ratio SINR is larger than 3dB, determining that the signal quality of the current service cell is good, namely determining that the current service cell meets the residence condition.
Here, when it is determined that the current serving cell meets the camping condition, that is, it indicates that the signal quality of the current serving cell is good, the terminal will not perform measurement on the neighboring cell in an idle state, but stably camp in the current serving cell, so that the power consumption of the terminal is saved, and meanwhile, the stability of terminal communication can be ensured.
In some embodiments, after stopping the measurement of the neighbor cell in the idle state, the method further comprises: when the current serving cell is determined not to meet the residence condition, recovering measurement of an adjacent cell in an idle state; or when the terminal is in a non-standby state, the measurement of the adjacent cell in an idle state is recovered; or when the terminal is in the connection state, the measurement of the adjacent cell in the idle state is recovered.
That is, when the reference signal received power RSRP of the current serving cell is smaller than the preset received power and/or the signal-to-noise ratio SINR is smaller than the preset signal-to-noise ratio, the measurement of the neighboring cell in the idle state is resumed.
Or, recognizing that the terminal is not static through a sensor arranged in the terminal, or recovering the measurement of the adjacent cell in an idle state when the terminal is on the screen.
Or, when the terminal enters the connected state, for example, if there is a called phone, the neighboring cell measurement in the idle state is resumed. The connection state means that information interaction exists between the terminal and the base station.
For the measurement of the neighboring cell in the recovery idle state, a specific example is as follows: if the neighboring cells of the serving cell a include a neighboring cell B, a neighboring cell C, and a neighboring cell D, the priority of the neighboring cell B is higher than the priority of the neighboring cell C, and the priority of the neighboring cell C is higher than the priority of the neighboring cell D, the terminal measures the signal quality respectively corresponding to the neighboring cell B, the neighboring cell C, and the neighboring cell D according to the identification information respectively corresponding to the neighboring cell B, the neighboring cell C, and the neighboring cell D in the system information sent by the base station, and can select a cell in which the terminal can reside from the neighboring cell B, the neighboring cell C, and the neighboring cell D by combining the signal quality and the priority of each neighboring cell.

According to the method and the device, the measurement of the adjacent cell in the idle state is stopped, so that the cell reselection is not performed, namely, the problem of frequent cell reselection is solved fundamentally.
Based on the foregoing embodiments, an embodiment of the present application provides a cell selection method, and fig. 2 is a second flowchart of the cell selection method in the embodiment of the present application, and as shown in fig. 2, the cell selection method may specifically include:
step 201: and when the terminal is determined to be in a standby state and the terminal is in an idle state, measuring the signal quality of the current service cell of the terminal to obtain a signal quality measurement index.
Here, the standby state refers to a state in which the terminal is powered on but does not perform any substantial work (e.g., does not operate on files and programs), i.e., the terminal is not used. Illustratively, in some embodiments, the determining that the terminal is in a standby state includes: identifying whether the terminal is static or not through a sensor built in the terminal; acquiring the screen-off duration of the terminal, and determining whether the screen-off duration exceeds a preset duration; and determining that the terminal is static, and determining that the screen-off duration exceeds the preset duration that the terminal is in a standby state.
The example terminal is in a static state and the screen-off duration exceeds the preset duration, and the terminal is determined to be in a standby state. For example, the preset time period may be set to 20 minutes.
For example, the sensor built in the terminal is an acceleration sensor, the acceleration sensor is used for measuring the acceleration of the terminal, the acceleration sensor outputs signals when the terminal moves in any direction, and the acceleration sensor does not output signals when the terminal is stationary, so that whether the terminal is stationary can be determined according to whether the acceleration sensor outputs signals. Or the sensor built in the terminal is a gyroscope sensor, the gyroscope sensor is used for measuring the rotation angle of the terminal, and when the rotation angle of the terminal is not changed, the terminal is determined to be static.
Here, the idle state refers to no information interaction between the terminal and the base station.
Here, the serving cell refers to a cell in which the terminal currently resides.
Here, the signal quality metric of the current serving cell includes at least one of: reference signal received power RSRP and signal to noise ratio SINR.
Step 202: determining whether the current serving cell meets the residence condition or not based on the signal quality measurement index of the current serving cell; if yes, go to step 203; if not; step 204 is performed.
In some embodiments, the residence conditions include: the reference signal receiving power is greater than a preset receiving power, and/or the signal-to-noise ratio is greater than a preset signal-to-noise ratio.
Here, the preset received power refers to a minimum reference signal received power for measuring a cell signal quality. The preset signal-to-noise ratio refers to the minimum signal-to-noise ratio for measuring the signal quality of the cell.
Illustratively, the predetermined received power may be-90 dBm and the predetermined signal-to-noise ratio may be 3 dB. Here, when the signal quality metric includes reference signal received power RSRP, and the reference signal received power RSRP is greater than-90 dBm, it is determined that the signal quality of the current serving cell is good, that is, it is determined that the current serving cell satisfies the camping condition. And when the signal quality measurement index comprises a signal to noise ratio SINR (signal to noise ratio), and the signal to noise ratio SINR is more than 3dB, determining that the signal quality of the current service cell is good, namely determining that the current service cell meets the residence condition. And when the signal quality measurement indexes comprise reference signal received power RSRP and signal to noise ratio SINR, and the reference signal received power RSRP is larger than-90 dBm and the signal to noise ratio SINR is larger than 3dB, determining that the signal quality of the current service cell is good, namely determining that the current service cell meets the residence condition.
Step 203: and stopping the measurement of the adjacent cells in the idle state.
That is, when it is determined that the current serving cell satisfies the camping condition, the terminal will not perform reselection measurement and stably camp in the current serving cell.
Step 204: and switching the terminal resident cell from the current service cell to the cell meeting the resident condition.
The serving cell of the terminal may change in an idle state. Here, when the current serving cell of the terminal satisfies the camping condition, the terminal stably camps on the current serving cell, and stops the measurement of the neighboring cell in the idle state. When the current service cell of the terminal does not meet the residence condition, the cell where the terminal resides is still switched, the switched service cell becomes the current service cell of the terminal, and the terminal continues to determine whether the current service cell meets the residence condition according to the signal quality measurement index of the current service cell until the current service cell is switched to the cell meeting the residence condition, so that the terminal can not execute reselection measurement and stably reside in the current service cell.
The cell selection method disclosed in the embodiments of the present application is used in any communication system, for example: GSM, belonging to a 2G network; WCDMA, belonging to 3G networks; LTE, belonging to 4G networks; NR, belonging to the 5G network.
By adopting the technical scheme, the terminal determines that the current serving cell meets the residence condition according to the signal quality measurement index of the current serving cell of the terminal, namely the signal quality of the current serving cell is good, and the terminal does not measure the adjacent cell in an idle state but stably resides in the current serving cell; otherwise, it indicates that the signal quality of the current serving cell is not good, and the terminal continues to measure the signal quality of the resident next serving cell until the resident serving cell with good signal quality is reached, so that the power consumption of the terminal can be saved, and meanwhile, the stability of terminal communication cannot be influenced.
Based on the foregoing embodiments, in some embodiments, before the measuring the signal quality metric of the current serving cell of the terminal, the method further includes: starting a timer; before the timer is overtime, determining the total times of switching of the current service cell of the terminal; after the timer is overtime, determining whether the total times is greater than a preset time; and when the total times is determined to be greater than the preset times, measuring the signal quality measurement index of the current service cell of the terminal.
Here, a timer is started, the total number of times that the serving cell of the terminal is switched during the starting period of the timer is counted, the total number of times is compared with a preset number of times, when the total number of times is greater than the preset number of times, it is indicated that the serving cell of the terminal is switched too frequently, and the terminal measures the signal quality of the current serving cell to select a cell capable of residing, so that the number of times of cell reselection can be reduced to a certain extent, and the power consumption of the terminal is saved. When the total times is less than or equal to the preset times, it indicates that the serving cell of the terminal is switched infrequently, and the terminal needs to perform neighbor cell measurement in an idle state, that is, measure the signal quality of all neighbor cells, and select a cell in which the terminal can reside from all neighbor cells.

Step 305: judging whether the timer is overtime; if yes, go to step 306; if not, go to step 303.
Step 306: judging whether the total times N are greater than a preset time N _ MAX or not; if not, go to step 307; if yes, go to step 308.
Step 307: and measuring the adjacent cells in an idle state.
Step 308: and measuring the Reference Signal Received Power (RSRP) and signal to noise ratio (SINR) of the serving cell.
Step 309: judging whether the RSRP is larger than-90 dBm or not and whether the SINR is larger than 3dB or not; if yes, go to step 310; if not, go to step 303.
Step 310: and stopping the measurement of the adjacent cells in the idle state.
Step 311: judging whether the RSRP is less than or equal to-90 dBm and/or the SINR is less than or equal to 3 dB; or whether the terminal is not stationary; or whether the terminal is on screen; or whether the terminal enters a service state; if any of the above cases is true, go to step 312; otherwise, the measurement of the adjacent cells in the idle state is still stopped.
Step 312: and recovering the measurement of the adjacent cells in the idle state.
Before the timer is overtime, each time a serving cell in which the terminal resides is switched, counting N and adding 1, and after the timer is overtime, judging whether N is greater than N _ MAX (the value can be 5 times); if not, the terminal considers that the current service cell of the terminal is not switched too frequently, and the terminal carries out adjacent cell measurement in an idle state; if so, the current service cell of the terminal is considered to be switched too frequently, then, whether the RSRP is greater than-90 dBm and whether the SINR is greater than 3dB is judged according to the Reference Signal Received Power (RSRP) and the signal to noise ratio (SINR) of the current service cell, if so, the terminal is considered not to execute reselection measurement and can stably reside in the current service cell, if not, whether the current service cell of the terminal is switched is judged, the service cell of the terminal is determined to be switched, the switched service cell becomes the current service cell of the terminal, and then, the step 309 is continuously executed until the RSRP of the current service cell of the terminal is greater than-90 dBm and is greater than 3dB, and the terminal does not execute reselection measurement and stably reside in the current service cell.
And after the idle-state adjacent cell measurement is stopped for a period of time, judging the values of the RSRP and the SINR again, and when the RSRP is less than or equal to-90 dBm and/or the SINR is less than or equal to 3dB, indicating that the quality of the current service cell is poor, and at the moment, the terminal recovers the idle-state adjacent cell measurement. Or the terminal is found to be not static, or the terminal is on screen, or the terminal enters a service state, and at the moment, the terminal recovers the measurement of the adjacent cell in an idle state.
The cell selection method disclosed in the embodiments of the present application is used in any communication system, for example: GSM, belonging to 2G networks; WCDMA, belonging to 3G networks; LTE, belonging to 4G networks; NR, belonging to the 5G network.

Secondly, the method and the device count the switching times of the service cell where the terminal resides by starting the timer, and determine that the switching is too frequent, the terminal measures the signal quality of the current service cell to select the cell where the terminal can reside, so that the cell reselection times can be reduced to a certain extent, and the power consumption of the terminal is saved.
