The 3GPP adopts the cellular form, and different frequency bands and frequency points are used under each cell. However, blind searching for the frequency point after the mobile terminal is powered on can lead to long time for the mobile terminal to power on and register the network, in order to accelerate the speed of the mobile terminal to power on and register the network, after the network is registered or after the network changes, the currently registered network environment information (including service cell information, frequency band, frequency point and the like corresponding to the network environment) can be stored in a file system of a communication module of the mobile terminal, and after the mobile terminal is powered on next time, historical frequency band frequency point information in the file system is preferentially searched, so that the purpose of rapidly finding the network is achieved.

Example 2
On the basis of embodiment 1, the present embodiment provides a method for writing to a flash memory. In this embodiment, the first reference time interval includes several time units, and the step S1 includes the following steps:
every time a time unit passes, acquiring a real-time service cell of the communication module, if the real-time service cell is not matched with the comparison service cell, adding 1 to the count value, and assigning a real-time setting value to the comparison service cell; and at the end of the first reference time interval, taking the ratio of the count value to the length of the first reference time interval as the change frequency, and clearing the count value.
As an alternative embodiment, the length of the first reference time interval is 1 minute and the time unit is 1 second.
Referring to fig. 4, in the present embodiment, step S2 includes the steps of:
step S21, determining whether the variation frequency is less than a preset threshold, if the variation frequency is less than the preset threshold, executing step S22, and if the variation frequency is greater than or equal to the preset threshold, executing step S23.
Step S22, judging whether the current service cell is matched with the reference cell, if the current service cell is matched with the reference cell, executing step S23; if the current serving cell does not match the reference cell, step S24 is performed.
And step S23, assigning the second reference time interval to the first reference time interval, and returning to step S1, wherein the second reference time interval has the same time length as the first reference time interval, and the starting point of the second reference time interval is not earlier than the end point of the first reference time interval.
And step S24, writing the current service cell into the flash memory to assign the current service cell to the reference cell.
In specific implementation, in step S1, the 1 minute time from the 0 th second to the 60 th second is used as the first reference time interval, and the serving cell of the communication module at the 0 th second is used as the comparison serving cell. At the 0 th second, the initial value of the count value is 0. And acquiring the real-time service cell of the communication module in the 1 st second. Then, it is determined whether the real-time serving cell matches the comparison serving cell. As an optional implementation, if the real-time serving cell and the comparison serving cell belong to the same cell, they are matched; if the two belong to different cells, the two do not match. If the two are matched, the communication module is considered to not change the cell, so that the service cell is considered not to be changed, and the counting value is not changed. If the two are not matched, the communication module is considered to change the affiliated cell due to movement, therefore, the counting value is added with 1 when the change of the serving cell is considered to occur, and the serving cell is updated to be the real-time serving cell, so that the change of the serving cell at the next second is judged. Next, the above steps are repeated at 2 nd second and 3 rd second … … th second, 60 th second, and the count value in the first reference time interval, that is, the value of the serving cell change of the communication module is acquired. Dividing the value of the change of the service cell of the communication module by the time length (1 minute) of the first reference time interval to obtain the change frequency of the service cell of the communication module in the first reference time interval, and then resetting the count value so as to recount in the next reference time interval (second reference time interval). In this embodiment, for a 2G (second generation mobile communication) network and a 3G (third generation mobile communication) network, a serving cell where a communication module is located may be obtained according to LAC (location area code) and cellid (a positioning technology); for a 4G (fourth generation mobile communication) network, a serving cell in which a communication module is located may be determined according to TAC (Tracking Area Code). The detailed implementation is not described herein.
After the next 60 th to 120 th seconds, after the 60 th seconds, step S21 is executed, the change frequency of the serving cell is compared with a preset threshold, if the change frequency of the serving cell is greater than or equal to the preset threshold, it is considered that the communication module is in the fast moving state within the 0 th to 60 th seconds, and with this as a reference, it may not be necessary to update the address in the file system in the 60 th to 120 th seconds, and then, the process proceeds to step S23, the 60 th to 120 th seconds (i.e., the time interval corresponding to the second reference time interval) are taken as the first reference time interval, and the process returns to step S1. The preset threshold value can be reasonably set as required. That is, if the communication module is in a fast moving state within the time from 0 th to 60 th seconds, the update of the file system is stopped between 60 th to 120 th seconds regardless of whether the serving cell of the communication module is changed or not between 60 th to 120 th seconds; however, between the 60 th second and the 120 th second, the change frequency of the serving cell of the communication module is still obtained according to the step S1, and is used as the evaluation basis of the next reference time interval.
In step S21, if the change frequency of the serving cell is less than the preset threshold, the communication module is considered to be in a slower moving state, and at this time, updating the address in the file system does not result in high-frequency writing of the flash memory. Then, on the one hand, the change frequency of the serving cell of the communication module between the 60 th second and the 120 th second is obtained according to the step S1 to be used as the evaluation basis of the next reference time interval; on the other hand, at the time of 61 th second, step S22 is executed to acquire the current serving cell of the communication module, and determine whether the current serving cell matches the reference cell. If the current serving cell matches the reference cell (i.e., belongs to the same cell), there is no need to update the serving cell information in the file system, and thus step S23 is performed. If the current serving cell does not match the reference cell (i.e., does not belong to the same cell), step S24 writes the current serving cell into the flash memory to assign a value to the reference cell. Next, at 62 seconds, step S22 is executed to acquire the current serving cell of the communication module and determine whether the current serving cell matches the reference cell. If the current serving cell matches the reference cell (i.e., belongs to the same cell), there is no need to update the serving cell information in the file system, and thus step S23 is performed. If the current serving cell does not match the reference cell (i.e., does not belong to the same cell), step S24 is performed to write the current serving cell into the flash memory to assign a value to the reference cell.
That is, in step S21, if the change frequency of the serving cell is less than the preset threshold, the communication module is considered to be in a slower moving state, and then in the following reference time interval, at the 61 st second and the 62 nd … … nd 120 th seconds of every elapsed time unit, the current serving cell of the communication module is respectively obtained, and it is determined whether the current serving cell matches with the reference cell. If the current serving cell matches the reference cell (i.e., belongs to the same cell), there is no need to update the serving cell information in the file system, and thus step S23 is performed. If the current serving cell does not match the reference cell (i.e., does not belong to the same cell), step S24 is performed to write the current serving cell into the flash memory to assign a value to the reference cell.
And at the 120 th second, reaching the end of the current reference time interval, and finishing the process of judging whether the service cell change of the communication module in the current reference time interval is written into the flash memory. Next, the next reference time interval is processed according to the change frequency of the serving cell of the communication module acquired from the 60 th to the 120 th seconds. According to the steps, the operation is repeated in a circulating mode.
According to the writing method of the flash memory, by detecting the frequency of the service cell switching of the communication module, frequent writing operation of the flash memory under the condition that the service cell switching of the communication module is frequent is effectively avoided, so that the service lives of the flash memory and the communication module are effectively prolonged.
On the basis of embodiment 1, this embodiment also provides a flash memory writing system. In this embodiment, the first reference time interval includes a plurality of time units, and the serving cell writing unit 12 is further configured to obtain a real-time serving cell of the communication module every time one time unit passes, and if the real-time serving cell is not matched with the comparison serving cell, the serving cell writing unit is further configured to add 1 to the count value and assign a real-time set to the comparison serving cell; at the end of the first reference time interval, the serving cell writing unit is further configured to use a ratio of the count value to the length of the first reference time interval as a change frequency, and clear the count value.
As an alternative embodiment, the length of the first reference time interval is 1 minute and the time unit is 1 second.
Referring to fig. 5, in the present embodiment, the serving cell writing unit 12 is further configured to write the current serving cell into the flash memory according to the following steps:
step S21, determining whether the variation frequency is less than a preset threshold, if the variation frequency is less than the preset threshold, executing step S22, and if the variation frequency is greater than or equal to the preset threshold, executing step S23.
Step S22, judging whether the current service cell is matched with the reference cell, if the current service cell is matched with the reference cell, executing step S23; if the current serving cell does not match the reference cell, step S24 is performed.
Step S23, assigning a second reference time interval to the first reference time interval, and calling the change frequency obtaining unit, where the second reference time interval has the same time length as the first reference time interval, and a start point of the second reference time interval is not earlier than an end point of the first reference time interval.
And step S24, writing the current service cell into the flash memory to assign the current service cell to the reference cell.
In specific implementation, first, the 1 minute time from the 0 th second to the 60 th second is used as a first reference time interval, and the serving cell of the communication module at the 0 th second is used as a comparison serving cell. At the 0 th second, the initial value of the count value is 0. At the time of 1 second, the change frequency acquisition unit 11 acquires the real-time serving cell of the communication module. Then, the change frequency acquisition unit 11 determines whether the real-time serving cell and the comparison serving cell match. As an optional implementation, if the real-time serving cell and the comparison serving cell belong to the same cell, they are matched; if the two belong to different cells, the two do not match. If the two are matched, the communication module is considered to not change the cell, so that the service cell is considered not to be changed, and the counting value is not changed. If the two are not matched, the communication module is considered to change the cell to which the communication module belongs due to movement, and therefore, the change frequency acquisition unit 11 determines that the serving cell change has occurred, adds 1 to the count value, and updates the serving cell to be the real-time serving cell, so as to determine the serving cell change at the next second. Next, at 2 nd second, 3 rd second … … th second 60 th, change frequency acquisition section 11 repeats the above process, and acquires the count value in the first reference time interval, that is, the value of the serving cell change of the communication module. The change frequency acquiring unit 11 divides the value of the change of the serving cell of the communication module by the time length (1 minute) of the first reference time interval to obtain the change frequency of the serving cell of the communication module in the first reference time interval, and then the change frequency acquiring unit 11 clears the count value to be recounted in the next reference time interval (second reference time interval). In this embodiment, the serving cell information of the communication module is obtained according to the disclosed technology of cellular mobile communication, and the specific implementation manner is not described herein again.
After the next 60 th to 120 th seconds and the 60 th seconds, step S21 is executed, the serving cell writing unit 12 compares the change frequency of the serving cell with a preset threshold, if the change frequency of the serving cell is greater than or equal to the preset threshold, it is considered that the communication module is in the fast moving state in the 0 th to 60 th seconds, and with this as a reference, it may not be necessary to update the address in the file system in the 60 th to 120 th seconds, and then, step S23 is entered, the 60 th to 120 th seconds (i.e., the time interval corresponding to the second reference time interval) are taken as the first reference time interval, and the change frequency acquiring unit is called to acquire the change frequency of the serving cell of the communication module in the 60 th to 120 th seconds. The preset threshold value can be reasonably set as required. That is, if the communication module is in a fast moving state within the time from 0 th to 60 th seconds, the update of the file system is stopped between 60 th to 120 th seconds regardless of whether the serving cell of the communication module is changed or not between 60 th to 120 th seconds; however, between the 60 th second and the 120 th second, the change frequency acquiring unit 11 still acquires the change frequency of the serving cell of the communication module according to the step S1, so as to serve as the evaluation basis of the next reference time interval.
In step S21, if the change frequency of the serving cell is less than the preset threshold, the communication module is considered to be in a slower moving state, and at this time, updating the address in the file system does not result in high-frequency writing of the flash memory. Then, on the one hand, the change frequency acquiring unit acquires the change frequency of the serving cell of the communication module between the 60 th second and the 120 th second according to the step S1 as the evaluation basis of the next reference time interval; on the other hand, at the time of 61 th second, step S22 is executed, change frequency acquisition unit 11 acquires the current serving cell of the communication module, serving cell writing unit 12 receives the current serving cell from change frequency acquisition unit 11, and determines whether the current serving cell matches the reference cell. If the current serving cell matches the reference cell (i.e., belongs to the same cell), there is no need to update the serving cell information in the file system, and thus step S23 is performed. If the current serving cell does not match the reference cell (i.e., does not belong to the same cell), step S24 is executed in which the serving cell writing unit 12 writes the current serving cell into the flash memory to assign a value to the reference cell. Next, at the 62 th second, returning to step S22, change frequency acquisition unit 11 acquires the current serving cell of the communication module, serving cell writing unit 12 receives the current serving cell from change frequency acquisition unit 11, and determines whether the current serving cell matches the reference cell. If the current serving cell matches the reference cell (i.e., belongs to the same cell), there is no need to update the serving cell information in the file system, and thus step S23 is performed. If the current serving cell does not match the reference cell (i.e., does not belong to the same cell), step S24 is executed in which the serving cell writing unit 12 writes the current serving cell into the flash memory to assign a value to the reference cell.
That is, in step S21, if the change frequency of the serving cell is less than the preset threshold, it is determined that the communication module is in a slower moving state, in the following reference time interval, at every 61 st second and 62 nd … … nd 120 th second after one time unit, the change frequency acquiring unit 11 respectively acquires the current serving cell of the communication module, and the serving cell writing unit 12 receives the current serving cell from the change frequency acquiring unit 11 and determines whether the current serving cell matches the reference cell. If the current serving cell matches the reference cell (i.e., belongs to the same cell), there is no need to update the serving cell information in the file system, and thus step S23 is performed. If the current serving cell does not match the reference cell (i.e. does not belong to the same cell), step S24 is executed, and the serving cell writing unit 12 writes the current serving cell into the flash memory to assign a value to the reference cell.
And at the 120 th second, reaching the end of the current reference time interval, and finishing the process of judging whether the service cell change of the communication module in the current reference time interval is written into the flash memory. Next, the next reference time interval is processed according to the change frequency of the serving cell of the communication module acquired from the 60 th to the 120 th seconds. According to the steps, the operation is repeated in a circulating mode.
The writing system of the flash memory of the embodiment effectively avoids frequent writing operation on the flash memory under the condition that the service cell of the communication module is frequently switched by detecting the frequency of switching the service cell of the communication module, thereby effectively prolonging the service lives of the flash memory and the communication module.
The present embodiment also provides a communication module, which includes a flash memory and the write system of the flash memory of the present embodiment. In the working process of the communication module, how the write-in system of the flash memory performs the write-in operation on the flash memory can refer to the write-in system of the flash memory of this embodiment, and details are not described here.
