detailed description

In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application.

Please refer to FIG. 1, which shows a communication system including: a base transceiver station (Base Transceiver Station, BTS) 10, a base station controller (Base Station Controller, BSC) 20, and a mobile switching center (Mobile Switching Center, MSC) 30 and mobile terminal 600.

BTS 10 is connected to BSC 20. BSC 20 has the function of controlling one or more BTSs. It is mainly responsible for wireless network resource management, cell configuration data management, power control, positioning and handover. BTS 10 is controlled by BSC 20, and is mainly responsible for wireless transmission, completing wireless and wired conversion, wireless diversity, wireless channel encryption, frame skipping and other functions.

BSC 20 is connected to MSC 30. MSC is the core of the communication system. It is the functional entity that controls and completes the exchange of voice channels for mobile stations (such as mobile terminal 600) located in the area it covers. It is also the communication system and other public communications. Interface between networks. It can complete the functions of network interface, common channel signaling system and billing, and can also complete the switching between the base station subsystem and the mobile switching center and auxiliary wireless resource management and mobility management.

The MSC 30 is also configured to interface with other networks. Among them, other networks include Public Switched Telephone Network (PSTN), Public Land Mobile Communication Network (PLMN), etc.

Among them, the area covered by wireless signals in mobile communication is called a cell, and generally refers to the range that a base station signal can cover. Generally speaking, a base station is a cell (a base station can also be divided into several cells, in which case the cell and the sector are equivalent), and the cell is divided into sectors (generally, a cell has one/two/ Three sectors, or even more), each sector then determines the number of carrier frequencies based on traffic.

The mobile terminal 600 needs to register in a certain cell to complete the network registration process before performing the actual service. The user can receive the service from the network only after successfully camping on the cell. After successfully camping on a cell, the mobile terminal will continue to perform the cell reselection process to maintain camping on a cell with better signal quality.

Specifically, cell reselection (cell reselection) refers to a process in which the mobile terminal selects a best cell to provide a service signal by monitoring the signal quality of the neighboring cell and the current cell in the idle mode. Among them, the neighboring cell is a neighboring cell different from the currently camped cell. Normally, when a mobile terminal accesses a cell and camps successfully, it will continue to measure its own cell. For example, based on the reference signal received power (ReferenceSignalReceivingPower, RSRP) measurement result S criterion (Srxlev), and compare it with the same frequency measurement start threshold (Sintrasearch) and different frequency / different system measurement start threshold (Snonintrasearch), As a decision condition for whether to start neighbor cell measurement.

However, the pseudo base station is an illegal base station outside the mobile communication network deployed by the telecommunications operator. In order to induce the mobile terminal to reselect to the cell of the pseudo base station, the transmission power is usually increased. When the mobile terminal is in the coverage area of the pseudo base station, the cell reselection is likely to reselect and camp on the cell of the pseudo base station. Among them, the mobile terminal is located in the coverage area of the pseudo base station. It may be that the mobile terminal moves into the coverage area of the pseudo base station, or the pseudo base station is moving to make the mobile terminal enter its coverage area.

The inventor found through research that if the mobile terminal has a small moving range, it may be within the coverage of the same legal cell with good signal quality, and it is not necessary to continuously measure the neighboring cell to select a neighboring cell to camp on . For example, the mobile terminal resides in a cell and has been active within the coverage of the cell, and the cell is the cell with the best signal quality within the mobile terminal's mobile range. At this time, even if the mobile terminal has been performing the cell reselection process, Will also choose to reside in the cell. However, if there is activity of the pseudo base station at this time, and the mobile terminal enters the coverage area of the pseudo base station cell, the mobile terminal may reselect to the pseudo base station.

Therefore, the embodiments of the present application provide a cell reselection processing method, device, mobile terminal, and storage medium, which are used to determine whether to suspend cell reselection of the mobile terminal according to the movement range of the mobile terminal, thereby reducing the mobile terminal reselection Times, reducing the probability of reselection to a pseudo base station.

The method, apparatus, mobile terminal, and storage medium for cell reselection provided in the embodiments of the present application will be described in detail below through specific embodiments.

Please refer to FIG. 2, which shows a processing method of cell reselection provided by an embodiment of the present application. The processing method of cell reselection determines the mobile range of the mobile terminal according to the current state of the mobile terminal. When the mobile range of the mobile terminal is smaller than the target range, the possibility of reselecting the cell of the mobile terminal to the pseudo base station is suspended. In a specific embodiment, the cell reselection processing method is applied to the cell reselection processing device 500 shown in FIG. 6 and the mobile terminal 600 configured with the cell reselection processing device 500 (FIG. 8) . It can be understood that the mobile terminal applied in this embodiment may be various devices that can perform cell reselection, such as a smart phone, a tablet computer, a wearable mobile terminal, an in-vehicle device, etc., and is not specifically limited herein. The specific process of this embodiment will be described below by taking a smartphone as an example. Specifically, as shown in FIG. 2, the method includes:

Step S110: Acquire the current state of the mobile terminal.

Step S120: Determine whether the moving range of the mobile terminal is smaller than the target range according to the current state.

In the process of using a mobile terminal by a user, it is possible that the user's range of motion is very small, so that the mobile terminal's range of motion is small or even unmoved, such as the user working in the office and moving at home. Therefore, it can be determined whether the mobile terminal's moving range is small according to the state of the mobile terminal.

Specifically, the current state of the mobile terminal, that is, the current state of the mobile terminal may be acquired, and the movement range of the mobile terminal may be determined according to the current state of the mobile terminal. Then, according to whether the moving range of the mobile terminal is smaller than the set target range, it is determined whether the moving range of the mobile terminal is small. The method for determining the mobile range of the mobile terminal according to the current state of the mobile terminal is not limited in this embodiment of the present application, and any state that can determine that the mobile range of the mobile terminal is small can be acquired to determine whether the mobile range of the mobile terminal is less than Target range.

Step S130: if yes, suspend cell reselection of the mobile terminal.

If the moving range of the mobile terminal is smaller than the target range, the mobile terminal can be kept in the current cell all the time without performing cell reselection. On the one hand, when the mobile range is smaller than the target range, the reselected pseudo base station can be avoided. On the other hand, the number of cell reselections for the entire mobile terminal is reduced, reducing the probability of reselection to a pseudo base station.

The processing method for cell reselection provided in the embodiment of the present application further includes starting reselection after suspending the reselection. Specifically, please refer to FIG. 3, the method includes:

Step S210: Obtain the current state of the mobile terminal.

Step S220: Determine whether the moving range of the mobile terminal is smaller than the target range according to the current state.

Step S230: If yes, suspend cell reselection of the mobile terminal.

If the moving range of the mobile terminal is smaller than the target range, it means that the spatial position of the mobile terminal does not change much, so that the cell reselection of the mobile terminal can be suspended to make the mobile terminal camp in the current cell.

In the embodiment of the present application, cell reselection may be suspended by suspending any node in the cell reselection process. Among them, the cells suspended for reselection may include 2G cells, 3G cells, and 4G cells, that is, suspension of access to new 2G base stations, 3G base stations, and 4G base stations.

In the cell reselection process of the mobile terminal, when the mobile terminal accesses the cell and camps successfully, it will continuously determine whether to start neighbor cell measurement. For example, as described above, the Srxlev (S criterion) is calculated according to the RSRP measurement result, or the comparison of the calculation result with Sintrasearch and Snonintrasearch is stopped as a judgment condition of whether to start the neighbor cell measurement. Therefore, as an embodiment, the manner of suspending cell reselection may be to stop judging whether to start neighbor cell measurement, for example, stop calculating the judgment condition of whether to start neighbor cell measurement.

In the cell reselection process of the mobile terminal, when the start condition of neighbor cell measurement is reached, neighbor cell measurement is performed. Therefore, as an embodiment, the way to suspend cell reselection may be to stop the neighboring cell measurement of the mobile terminal.

In the cell reselection process of the mobile terminal, the neighboring cell measurement determines that the signal quality of the neighboring cell is better than that of the current cell. If the reselection conditions are met, the cell reselection is performed, the cell is reselected to the neighboring cell and resides. Therefore, as an embodiment, the way to suspend cell reselection may be to prohibit the trigger of cell reselection.

In addition, optionally, because the mobile terminal is in a flight mode, the communication modules such as GSM and GPRS of the mobile terminal are turned off, the mobile terminal will not actively send a paging signal to the base station, and will not perform the operation of accessing the cell. Moreover, in some cases, such as nighttime, the user has no communication requirements. Therefore, in the embodiment of the present application, the way to suspend cell reselection may also be to set the mobile terminal to the flight mode.

For users, the time with a small range of activities may have certain rules, such as at night, during working hours on weekdays, etc. The time when the user usually has a small range of activity may be used as the specified time interval. Within the specified time interval, the mobile terminal has a smaller possibility of moving less, and is more likely to obtain good cell service without performing cell reselection. Therefore, optionally, in the embodiment of the present application, a determination may be made whether the cell suspends reselection within a specified time interval. The specified time interval may be set in advance and stored in the mobile terminal, or may be set according to the activity rule of the mobile terminal. For example, the designated time interval is set in advance from 11 o'clock at night to 7 o'clock in the morning. For another example, if it is counted that the mobile range of the mobile terminal is smaller than the target range from 9 am to 6 pm from Monday to Friday for multiple consecutive weeks, then the specified time interval is set to be from 9 am to 6 pm from Monday to Friday.

As an embodiment, the determination of whether the cell is suspended and restarted within the specified time interval may be that, when it is determined that the movement range of the mobile terminal is smaller than the target range, it is then determined whether the current time is within the specified time interval. If the current time is within the specified time interval, cell reselection of the mobile terminal is suspended. Improve the accuracy of judgment by specifying a time interval.

As an implementation manner, the determination whether the cell is suspended and restarted within the specified time interval may be to determine whether the current time is within the specified time interval, and if so, step S210 is executed again. That is, when it is determined that the current time is within the specified time interval, the current state of the mobile terminal is acquired again, so as to determine whether the moving range of the mobile terminal is smaller than the target range according to the current state of the mobile terminal. This embodiment can reduce the number of times that the mobile terminal acquires the current state to determine the movement range, reduce the data processing amount of the mobile terminal, and reduce power consumption.

Optionally, in the embodiment of the present application, the manner of suspending reselection may also be determined according to a specific time interval. For example, during the day, users have communication needs such as phone calls and short messages. They can suspend cell reselection through nodes that suspend the cell reselection process. At night, the user may not have communication requirements, so the cell reselection is suspended through the flight mode. The time interval can be determined according to the user's settings or user's usage habits.

In the embodiment of the present application, if the moving range of the mobile terminal is greater than or equal to the target range, it means that the mobile terminal is in the process of movement, and it is likely to move out of the coverage of the current cell. Therefore, if it is determined in step S220 that the moving range of the mobile terminal is If it is greater than or equal to the target range, the cell reselection process continues.

Step S240: If the mobile range of the mobile terminal is greater than the target range, start cell reselection of the mobile terminal.

After suspending cell reselection of the mobile terminal, if the mobile terminal moves too far, it may move out of the coverage of the currently camped cell, or move to a location where the signal quality of the currently camped cell is poor. In this case, in order to ensure the signal quality of the mobile terminal, cell reselection of the mobile terminal may be started.

Specifically, if the mobile range of the mobile terminal is greater than the target range, the cell reselection of the mobile terminal is restarted. Optionally, the target range in this step may be the same range as the target range described in step S220, or may be a different range than that in step S220.

Optionally, the moving range in this step may be a moving range formed by continuing to move on the basis of the moving range in step S220.

Optionally, the movement range in this step may also be a movement range formed by the movement of the mobile terminal after suspending cell reselection. In this case, the target range in this step may be smaller than the target range in step S220. Of course, it may be the same range as the target range in step S220.

Wherein, initiating cell reselection of the mobile terminal may be initiated corresponding to the suspended node of cell reselection. For example, if the way to suspend cell reselection is to stop judging whether to start neighbor cell measurement. When the cell reselection of the mobile terminal is started, the judgment on whether to start neighbor cell measurement is started to form a complete cell reselection process.

If the method of suspending cell reselection is to stop the neighboring cell measurement of the mobile terminal. When the cell reselection of the mobile terminal is started, the neighbor cell measurement process of the mobile terminal is started, so that when the neighbor cell measurement conditions are met, the neighbor cell measurement is started.

If the method of suspending cell reselection is to prohibit the trigger of cell reselection, when the cell reselection of the mobile terminal is started, the trigger of cell reselection is turned on. Therefore, when a cell satisfying the reselection condition is measured, the mobile terminal can reselect and camp on the cell satisfying the reselection condition.

In the embodiment of the present application, if the way to suspend cell reselection is to set the mobile terminal to the flight mode, the cell reselection to start the mobile terminal may be to turn off the flight mode of the mobile terminal so that the communication module of the mobile terminal is turned on For cell access.

In the embodiment of the present application, the mobile terminal suspends the reselection of the cell when the moving range is smaller than the target range, thereby avoiding reselection to the pseudo base station cell when the moving range is small. After the mobile terminal suspends cell reselection, if the mobile range of the mobile terminal is greater than the target range, the cell reselection of the mobile terminal is enabled to enable the mobile terminal to connect to a cell with better signal quality. In the embodiment of the present application, the probability of the mobile terminal reselecting to the pseudo base station can be reduced, and the mobile terminal can be connected to a cell with good signal quality.

The processing method for cell reselection provided in the embodiment of the present application can determine the movement range of the mobile terminal according to the movement state of the mobile terminal. Specifically, please refer to FIG. 4, the method includes:

Step S310: Obtain the motion state of the mobile terminal.

The movement of the mobile terminal may form the movement range of the mobile terminal, therefore, the current state of the acquired mobile terminal may be the movement state of the acquired mobile terminal.

The motion state of the mobile terminal can be obtained in real time, or the motion state of the mobile terminal can be obtained periodically, which is not limited in the embodiments of the present application.

In the embodiment of the present application, the manner of acquiring the movement state of the mobile terminal is not limited. As a first implementation manner, the movement state of the mobile terminal can be obtained through the positioning information of the mobile terminal. Wherein, the positioning information may be Global Positioning System (Global Positioning System, GPS) data, which is used to indicate the real-time position of the mobile terminal.

As a second implementation manner, since the posture sensor built in the mobile terminal can detect the motion state of the mobile terminal, the motion state of the mobile terminal can be obtained by acquiring data of the posture sensor of the mobile terminal. Among them, the posture sensors of the mobile terminal include accelerometers, gyroscopes and other sensors that can detect the mobile terminal motion state.

Step S320: Determine whether the movement range of the mobile terminal within the target duration is less than the target range according to the movement state.

In the embodiment of the present application, a target range may be set. The target range may be the size of a space area, such as a horizontal annular space with a radius of 0.1 km. The specific size of the target range is not limited in the embodiments of the present application, and may be the smallest range that can be covered by one cell, or may be smaller than the coverage range of one cell.

The target range is used to determine whether the mobile range of the mobile terminal is small. Specifically, it may be that after the mobile terminal reselects to camp on a cell, if the mobile terminal's moving range is smaller than the target range, it may be determined that the mobile terminal's moving range is small.

In the embodiment of the present application, it can be determined whether the movement range of the mobile terminal is small according to whether the movement range of the mobile terminal within the target duration is smaller than the target range. For example, the mobile terminal is located at the first position at the first time, and the time at the first time plus the target duration is the second time, and the mobile terminal moves to the second position. Between the first time and the second time, the movement range of the mobile terminal formed by the first position and the second position is within the target range, it is determined that the movement range of the mobile terminal is smaller than the target range. If the mobile range of the mobile terminal is greater than the target range at any time between the first time and the second time, it can be determined that the mobile range of the mobile terminal is greater than the target range. If at any two moments between the first moment and the second moment, the distance between the positions corresponding to the mobile terminals is greater than the distance covered by the target range, then the mobile range of the mobile terminal is determined to be greater than the target range.

Optionally, the first time may be any time, that is, from any time, it is determined whether the moving range of the mobile terminal is smaller than the target range.

Optionally, the first moment may also be the last second moment.

Optionally, the first moment may also be a moment when it is determined that the movement range of the mobile terminal is greater than the target range. That is, when it is determined that the movement range of the mobile terminal is greater than the target range, the time is used as the starting time to determine whether the movement range of the mobile terminal is less than the target range.

Optionally, the first moment may also be the moment when the mobile terminal reselects and camps on a cell. That is, after the mobile terminal reselects and camps on a cell, it starts to determine whether the mobile range of the mobile terminal is smaller than the target range.

In the embodiments of the present application, various first-time implementations may also be combined with each other. For example, it is determined from any time whether the moving range of the mobile terminal is smaller than the target range. When it is determined that the movement range of the mobile terminal is greater than the target range, the determined time is used as the first time to continue to determine whether the movement range of the mobile terminal is less than the target range.

The specific time length of the target time length can be set in advance, and the specific value is not limited in the embodiments of the present application, such as 5 minutes, 10 minutes, and so on.

Corresponding to the above-mentioned first embodiment, if the movement state of the mobile terminal is determined through the positioning information of the mobile terminal, in the embodiment of the present application, the location trajectory of the mobile terminal can be determined according to the positioning information of the mobile terminal at various times to determine the position Whether the trajectory is within the target range. If the range delineated by the location trajectory of the mobile terminal is within the target range, it can be determined that the mobile range of the mobile terminal is smaller than the target range.

Or, between the first time and the second time, it is determined whether there are two positions with a distance greater than the distance covered by the target range among the positions corresponding to the mobile terminal. If not, it is determined that the moving range of the mobile terminal is smaller than the target range, and if so, it is determined that the moving range of the mobile terminal is larger than the target range. For example, the target range is a horizontal space with a radius of 0.1 km. Between the first time and the second time, the two farthest positions corresponding to the mobile terminal are the first position and the second position. The first position and the second position The horizontal distance between the two positions is 0.15 kilometers, which means that the range of motion of the mobile terminal is smaller than the target range.

Corresponding to the second embodiment described above, if the motion state of the mobile terminal is determined through the data of the posture sensor of the mobile terminal, in the embodiment of the present application, the motion trajectory of the mobile terminal within the target duration can be determined according to the posture sensor data. Specifically, it may be that the movement direction of the mobile terminal and the distance in the movement direction within the target duration from the first moment to the second moment are determined from the data of the attitude sensor, so that the movement terminal and the distance can be combined to obtain the mobile terminal Movement track. For example, according to the target duration from the first time to the second time, according to the acceleration value of the mobile terminal detected in the three-dimensional direction detected by the accelerometer, the movement speed of the mobile terminal and the displacement in the three-dimensional direction can be calculated. Then, according to the data of the gyroscope, the deflection of the mobile terminal at various times within the target duration is determined, so as to obtain the trajectory of the mobile terminal in combination with the deflection, movement speed, and displacement of the mobile terminal.

According to the movement trajectory of the mobile terminal, it is determined whether the movement range of the mobile terminal is smaller than the target range. Specifically, it may be determined whether the corresponding spatial range of the motion track is smaller than the target range, and if so, it is determined that the motion range of the mobile terminal is smaller than the target range. If at any time between the first time and the second time, the range delineated by the movement trajectory of the mobile terminal exceeds the target range, it can be determined that the mobile range of the mobile terminal is greater than the target range.

In the embodiment of the present application, if the mobile terminal is stationary, it can be determined that the mobile terminal has a small motion range. Therefore, corresponding to the above-mentioned second embodiment, if the movement state of the mobile terminal is determined by the data of the attitude sensor of the mobile terminal, in the embodiment of the present application, it can also be determined whether the mobile terminal is stationary beyond the target duration according to the attitude sensor data . If the mobile terminal is stationary for more than the preset duration, it is determined that the movement range of the mobile terminal within the target duration is smaller than the target range. For example, if the accelerometer detects that the mobile terminal is only subjected to gravitational acceleration, and the gyroscope detects that the mobile terminal is rotating and determines that the mobile terminal is stationary.

Step S330: If yes, suspend cell reselection of the mobile terminal.

If the movement range of the mobile terminal within the target duration is smaller than the target range, the cell reselection of the mobile terminal is suspended to avoid reselection to the pseudo base station.

Optionally, after the cell reselection is suspended, in order not to affect the communication of the mobile terminal, it may continue to determine whether the mobile range of the mobile terminal is greater than the target range according to the current state of the mobile terminal to determine whether to reselect to initiate cell reselection of the mobile terminal .

Optionally, in order to prevent the movement range of the mobile terminal from being excessively large due to accumulation, the movement range of the mobile terminal that is continuously determined after the reselection suspension may be a range based on the movement range determined before the reselection suspension. For example, when determining the moving range of the mobile terminal within the target duration in step S320, it is determined that the mobile terminal is located at the first position at the first moment, and the mobile terminal is located at the second position at the second moment. The motion range is smaller than the target range. Then, the first position at the first moment is used as a criterion to determine the movement range of the mobile terminal between the current moment and the first moment, and determine whether the movement range is greater than the target range. Specifically, the mobile terminal's moving range can be determined by positioning information or attitude sensor data of the mobile terminal.

Optionally, in the embodiment of the present application, if the mobile terminal is stationary for more than a preset duration in step S320, it is determined that the movement range of the mobile terminal within the target duration is smaller than the target range. After pausing cell reselection, continue to determine whether the mobile terminal is stationary. If the mobile terminal remains stationary, cell reselection remains suspended. If the mobile terminal is no longer stationary, for example, the accelerometer detects an acceleration different from the acceleration of gravity, or the gyroscope detects the rotation of the mobile terminal, etc., it is determined that the mobile terminal is moving, and cell reselection is initiated.

In the embodiment of the present application, if the moving range of the mobile terminal is too large, the signal of the cell where it currently resides may become weak, and it is necessary to start cell reselection. Therefore, optionally, it may also be determined whether the mobile terminal initiates cell reselection based on the signal strength of the cell where the mobile terminal resides. Specifically, it may be determined whether the signal of the cell where the mobile terminal is camping is less than the first signal value, and if so, it is determined that the mobile range of the mobile terminal is greater than the target range. Or, it is determined whether the signal of the cell where the mobile terminal is camping is less than the first signal value, and if so, the cell reselection of the mobile terminal is started.

The specific size of the first signal value is not limited in the embodiment of the present application, and may be a signal value that may affect the communication quality of the mobile terminal, such as 5 dBm, 10 dBm, and so on.

In the embodiment of the present application, the movement range of the mobile terminal is determined by the movement state of the mobile terminal, the obtained movement range is more intuitive, and the comparison with the target range is more accurate, thereby more accurately controlling the start or suspension of cell reselection.

In the embodiment of the present application, the target range may also be the range of the mobile terminal in a certain state. That is, the mobile terminal is in a certain state, the mobile range of the mobile terminal is considered to be smaller than the target range. The processing method for cell reselection provided in the embodiment of the present application can also be used to indicate whether the mobile terminal's moving range is too large based on the network connection status of the mobile terminal. That is, in the embodiment of the present application, the movement range of the mobile terminal may be determined according to the network connection state of the mobile terminal. Specifically, please refer to FIG. 5, the method includes:

Step S410: Acquire the Wi-Fi connection status of the mobile terminal.

Step S420: Determine whether the mobile terminal is connected to the same Wi-Fi within the target duration.

In the embodiment of the present application, the acquired current state of the mobile terminal may be the Wi-Fi connection state of the mobile terminal. When the mobile terminal is connected to Wi-Fi, it can be determined which Wi-Fi the terminal is currently connected to. Specifically, the Wi-Fi can be distinguished by the Wi-Fi identity. Wherein, optionally, the Wi-Fi identity may be the SSID (Service Set Identifier) of Wi-Fi, that is, the name of Wi-Fi. In addition, the identity of Wi-Fi can also be the BSSID of Wi-Fi, that is, the mac address of Wi-Fi.

It is understandable that since the location of the router is usually fixed, the Wi-Fi coverage corresponding to the router is within a fixed range, and usually the range is not large. Therefore, in the embodiment of the present application, if the mobile terminal is connected to the same Wi-Fi, it can be determined that the mobile terminal has a smaller moving range within the time range connected to the same Wi-Fi, and the same Wi-Fi Signal coverage. Among them, the same Wi-Fi may be Wi-Fi with the same identity.

Specifically, in the embodiment of the present application, when determining whether the mobile range of the mobile terminal is smaller than the target range according to the current state, it may be determined whether the mobile terminal is connected to the same Wi-Fi. Optionally, when used as a determination of whether to perform cell reselection, it may be determined whether the mobile terminal is connected to the same Wi-Fi within the target duration. If the mobile terminal is connected to the same Wi-Fi within the target duration, it can be determined that the mobile range of the mobile terminal is smaller than the target range.

After the mobile terminal newly registers and connects to a Wi-Fi, it can record the Wi-Fi for the next connection. And for the Wi-Fi that has been registered and connected, it is more certain that it is located in a fixed location and its signal coverage is limited. Therefore, optionally, in the embodiment of the present application, it may also be determined whether the Wi-Fi to which the mobile terminal is connected is a connected and recorded Wi-Fi. If it is connected and recorded Wi-Fi, it can be determined that the mobile terminal's moving range is smaller than the target range.

Step S430: If yes, suspend cell reselection of the mobile terminal.

If the mobile terminal is connected to the same Wi-Fi within the target duration, it indicates that the mobile terminal's movement range is within the Wi-Fi signal coverage, and its position is basically fixed. At this time, the mobile terminal's cell reselection can be suspended to make the mobile The terminal resides in the currently selected cell.

After the cell reselection is suspended, if the mobile terminal moves too far, it may move out of the coverage of the currently camped cell or move to a location where the currently camped cell has a poor signal. If the suspension of cell reselection continues at this time, the use of the communication function of the mobile terminal may be affected. Therefore, after the cell reselection is suspended, it may continue to determine whether the mobile range of the mobile terminal is too large according to the current state of the mobile terminal to determine whether to initiate cell reselection.

Since the mobile terminal's moving range is too large, it will move out of the coverage of the currently connected Wi-Fi. Therefore, optionally, in the embodiment of the present application, whether the Wi-Fi signal connected to it is weaker than a lower signal threshold can be used to determine whether the mobile range of the mobile terminal is too large. Specifically, it may be determined whether the Wi-Fi signal to which the mobile terminal is connected is less than the second signal value. If it is less than the second signal value, it is determined that the mobile range of the mobile terminal is greater than the target range, and cell reselection of the mobile terminal needs to be initiated. The specific size of the second signal value is not limited in the embodiment of the present application, and may be when the distance between the mobile terminal and the router is greater than a distance used to characterize the target range. For example, the second signal value may be 5 dBm or 10 dBm.

Of course, optionally, in the embodiment of the present application, at the same time, it may also be determined whether to initiate cell reselection according to whether the signal of the cell where the mobile terminal resides is less than the first signal value.

In the embodiment of the present application, the size of the mobile terminal's moving range is determined by whether the mobile terminal is connected to the same Wi-Fi, so that the start or suspension of cell reselection is determined according to whether the mobile terminal is connected to the same Wi-Fi, and the determination method is simple.
