[0002] According to the 3GPP protocol, in the dedicated mode of the GSM network, the UE user equipment will control whether to trigger Radio Link Failure based on whether the SACCH message can be decoded and the RADIO_LINK_TIMEOUT parameter sent to the UE by the network. The parameter setting value of the RADIO_LINK_TIMEOUT parameter control is based on the one sent by the network, which will result in most or even all SACCH messages being unable to be decoded when the downlink signal is weak or the downlink interference is large. It is necessary to subtract the setting value sent by the network until the RADIO_LINK_TIMEOUT setting value reaches 0 before operations such as cell selection or cell reselection can be performed. This way of setting the setting value of the radio link timeout results in a long judgment process, affects the reselection of the channel, and has poor efficiency in communication operations.

[0021] The present application selects a minimum setting value from the setting value of the wireless link timeout issued by the network and the setting value of the wireless link timeout maintained by the database as the initial setting value of the wireless link timeout for this communication operation when initiating a communication operation on the channel, thereby reducing the starting value of the initial setting value. If the channel signal is not good or poor, the initial setting value of the wireless link timeout can be quickly reduced to 0 through the judgment of the wireless link timeout, thereby reducing the judgment process and number of times, saving operation time, quickly disconnecting the operation of the current channel, and starting communication on a new channel, reducing the impact on the communication operation, and improving the reliability and efficiency of the communication operation.

[0046] Those skilled in the art will understand that Figure 1 The structure of the mobile terminal shown in the figure does not constitute a limitation on the terminal, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0047] exist Figure 1 In the mobile terminal shown, the processor 1001 is used to execute the communication control application in the memory 1003 to implement the following steps:

[0048] Receive the setting value of the wireless link timeout sent by the network, and obtain the setting value of the wireless link timeout stored in the database;

[0049] Selecting a minimum setting value for the wireless link timeout from the setting value for the wireless link timeout sent by the network and the setting value for the wireless link timeout stored in the database as a standard setting value for the wireless link timeout;

[0050] When it is determined that the wireless link fails according to the standard setting value of the wireless link timeout, a new channel is selected to complete the communication operation.

[0051] refer to Figure 2 , Figure 2 This is a schematic diagram of the operation flow of the communication control method of the present application; the communication control method comprises:

[0052] Step S10, receiving a setting value of a wireless link timeout sent by a network, and acquiring the setting value of the wireless link timeout stored in a database;

[0053] According to the 3GPP protocol, in the dedicated mode of the GSM network, the UE user equipment (for example, a mobile terminal) will control whether to trigger the Radio Link Failure wireless link failure based on whether it can decode the SACCH (Slow Associated Control Channel) message and the RADIO_LINK_TIMEOUT wireless link timeout parameter sent by the network to the UE. The specific algorithm is as follows:

[0054] The UE maintains a parameter S, and the initial value of S is equal to the setting value of the radio link timeout RADIO_LINK_TIMEOUT; the UE continuously receives SACCH messages. If a SACCH message can be decoded correctly, the S value is increased by 2 (but the maximum does not exceed RADIO_LINK_TIMEOUT); if a SACCH message cannot be decoded, the S value is reduced by 1; if there is a channel change, the UE will reset the S value; when the S value is reduced to 0, it will trigger a Radio Link Failure, and the connection in dedicated mode will be disconnected. When initiating a wireless link communication operation, the network will send down a radio link timeout setting value S, and the database will also save the previously used or adjusted radio link timeout setting value. When receiving the radio link timeout setting value S sent by the network, the radio link timeout setting value S1 stored in the database is obtained.

[0055] Step S20, selecting a minimum setting value of the wireless link timeout from the setting value of the wireless link timeout sent by the network and the setting value of the wireless link timeout stored in the database as a standard setting value of the wireless link timeout;

[0056] When executing a communication operation, a setting value for a wireless link timeout is maintained. The setting value for the wireless link timeout monitors the communication quality of the wireless link and determines whether the received wireless link information can be parsed successfully. For example, in a dedicated mode, whether the transmitted slow associated control channel message can be decoded successfully. If it cannot be decoded successfully, it is necessary to reduce the setting value for the wireless link timeout. The setting value for the wireless link timeout is maintained in the database, and a modified setting value for the wireless link timeout is maintained that is smaller than the setting value issued by the network. When the network issues the setting value for the wireless link timeout, a minimum setting value for the wireless link timeout is selected from the setting value maintained in the database and the setting value for the wireless link timeout issued by the network as the standard setting value S0 for the wireless link timeout. This value is used as the initial value to determine whether to start the judgment basis for the wireless link failure.

[0057] Step S30: When it is determined that the wireless link fails according to the standard setting value of the wireless link timeout, a new channel is selected to complete the communication operation.

[0058] When the standard setting value S0 of the wireless link timeout is 0, the wireless link fails, the communication of the wireless link needs to be abandoned, and a new channel needs to be started to complete the communication operation. After selecting a minimum standard setting value S0 of the wireless link timeout, the increase and decrease operation is completed according to this standard setting value S0 to determine whether it is reduced to 0, because the setting value of the wireless link timeout is reduced in the initial setting value, which is smaller than the one sent by the network, and the starting point is lower. It is easier to reduce to 0 faster when the wireless link times out, triggering the failure of the wireless link, and opening other channels to complete the communication operation, which reduces the judgment time, can quickly transfer to a channel with better signal to complete the communication operation, and improves the efficiency of the communication operation.

[0059] This embodiment selects a minimum setting value from the setting value of the wireless link timeout sent by the network and the setting value of the wireless link timeout maintained by the database as the initial setting value of the wireless link timeout for this communication operation when initiating a communication operation on the channel, thereby reducing the starting value of the initial setting value. If the channel signal is not good or poor, the initial setting value of the wireless link timeout can be quickly reduced to 0 through the judgment of the wireless link timeout, thereby reducing the judgment process and number of times, saving operation time, quickly disconnecting the operation of the current channel, and starting communication on a new channel, reducing the impact on the communication operation, and improving the reliability and efficiency of the communication operation.

[0060] In one embodiment of the present application, reference Figure 3 , after the step of selecting a new channel to complete the communication operation when the wireless link fails according to the standard setting value of the wireless link timeout, the method further includes:

[0061] Step S40, receiving a slow associated control channel message sent by the network;

[0062] Step S50, when decoding of the slow associated control channel message fails, reducing the standard setting value of the radio link timeout according to the first step;

[0063] Step S60: When the standard setting value of the wireless link timeout is reduced to 0, the standard setting value of the wireless link timeout reduced by the first setting value is saved in the database.

[0064] When performing the judgment operation of radio link failure according to the standard setting value S0 of radio link timeout, it is judged whether the received SACCH (Slow Associated Control Channel) message can be successfully decoded. If it can be successfully decoded, it means that there is no problem with the channel data transmission. If it cannot be decoded or the decoding fails, it is necessary to reduce the standard setting value S0 of radio link timeout by 1, that is, the first step length is 1. As long as the SACCH message decoding fails, the standard setting value S0 of radio link timeout is reduced by 1. If the standard setting value S0 of radio link timeout is reduced to 0, it is determined that the radio link fails, and other channels need to be reopened to complete the communication operation, the data transmission of the channel of the current cell is abandoned, and the communication operation of the channel of another new cell is opened. By continuously parsing the received SACCH message, the decoding fails continuously until the standard setting value S0 of radio link timeout is reduced to 0, the radio link fails. The radio link failure is triggered in the current channel, that is, the signal and quality of the current channel are poor, and the setting value of the radio link timeout needs to be reduced. Otherwise, the standard setting value S0 of the previous radio link timeout is used next time, which will waste time in judgment. Therefore, the standard setting value of the wireless link timeout that reduces the first setting value is saved to the database as the setting value of the wireless link timeout when the channel is used next time; in this way, there will be a setting value of the wireless link timeout that is smaller than the standard setting value S0 of the wireless link timeout in the database. When the channel is enabled to perform communication operations, the setting value of the wireless link timeout judgment will be reduced, and it will not waste too much judgment time, so that the wireless link failure and the wireless link disconnection can be quickly judged. The first setting value can be 20 or 30, and it is modified according to the size of the standard setting value S0 of the wireless link timeout. For example, if the standard setting value S0 of the wireless link is 60, the first setting value is 40; or if the standard setting value S0 of the wireless link is 30, the first setting value is 15; if the standard setting value S0 of the wireless link is 10, the first setting value is 2, etc. The larger the standard setting value S0 of the wireless link timeout is, the larger the first setting value is; the smaller the standard setting value S0 of the wireless link timeout is, the smaller the first setting value is. After the first setting value is reduced, it is saved in the database for the next use of the standard setting value S0 of the wireless link timeout after the setting value is reduced to determine the timeout of the wireless link. The present application also sets a minimum threshold value. For example, the standard setting value S0 of the wireless link timeout is 4. When the standard setting value of the wireless link timeout is reduced by the setting value, if it is reduced from 5 to 2 to 3, the standard setting value S0 of the wireless link timeout is saved as 4.

[0065] The first step length is a value different from the first set value. Generally speaking, the first step length is smaller than the first set value. Of course, in some cases, for example, when the standard setting value is relatively small, for example, 8 or 5, the first step length can be the same as the first set value.

[0066] The embodiment of the present application adjusts the setting value of the wireless link timeout of the channel after a channel triggers a wireless link failure, reduces the setting value and saves it to the database, so that when performing subsequent communication operations on the channel, the initial value can be lowered when making a wireless link failure judgment. In this way, the judgment of the wireless link failure can be completed quickly, the judgment process is reduced, time is saved, and the efficiency of communication operations is improved.

[0067] In one embodiment, reference Figure 4 , after the step of reducing the standard setting value of the radio link timeout according to the first step when decoding the slow associated control channel message fails, the method further includes:

[0068] Step S70: After performing at least one reduction operation according to the set step length, if the slow associated control channel message is decoded successfully, the standard setting value of the radio link timeout after performing the reduction operation is saved in the database.

[0069] When executing the standard setting value S0 of the wireless link timeout to be reduced according to the set step length, for example, after each failed parsing of the SACCH message, it is reduced by 1, and after the decoding of the SACCH message fails at least once, that is, the standard setting value S0 of the wireless link timeout is reduced at least once, and before the standard setting value S0 of the wireless link timeout is reduced to 0, the decoding of the SACCH message is successful, then the setting value of the wireless link timeout after the reduction operation is saved to the database. The setting value of the wireless link timeout is reduced, so that the starting judgment value of the channel is reduced, so that there is no need to perform the timeout judgment of the channel, and the judgment is made according to the fixed high setting value of the wireless link timeout, which reduces the number of judgments, improves the efficiency of communication operations, and can quickly switch to a new channel to perform communication operations.

[0070] In one embodiment, reference Figure 5 , after the step of reducing the standard setting value of the radio link timeout according to the set step size when decoding the slow associated control channel message fails, it also includes:

[0071] Step S80: When the number of reductions reaches a preset number, the standard setting value of the wireless link timeout is reduced according to a second step length, and the second step length is greater than the first step length.

[0072] The preset number of times can be 2 or 3 times, or can be set to a larger value, for example, 5 or 6 times, according to the signal quality of the channel history. For example, the better the quality, the larger the number of times, and the worse the quality, the smaller the number of times. When the preset number of times is reached, that is, when the number of failed SACCH message decoding reaches the preset number of times, the second step length of each reduction is increased, that is, the second step length is greater than the first step length; for example, it is reduced by 1 before, and then reduced by 2 after the increase, and the standard setting value of the wireless link timeout can be quickly reduced to 0 through the second step length, and the judgment of the wireless link failure is completed, which speeds up the operation process, quickly reaches the judgment of the wireless link failure, saves the judgment process, and can select a new channel in advance to perform communication operations, thereby improving the efficiency of communication.

[0073] In other embodiments of the present application, after the number of times the standard setting value of the wireless link timeout is reduced reaches a preset number, for example, 2 or 3 times, the step size is increased. For example, the previous initial value was 10, which is reduced from 2 to 8. After the step size value is increased by the second step, it is reduced from 8 to 3 to 5, so that the initial value drops quickly, reducing the judgment process, saving time, and improving the efficiency of communication operations.

[0074] In one embodiment, reference Figure 6 The step of obtaining the setting value of the wireless link timeout stored in the database includes:

[0075] Step S11, determining the identification message of the currently used channel;

[0076] Step S12: Acquire a setting value of a wireless link timeout corresponding to the identification information from a database, wherein the identification information includes at least one of a location area number, a cell number, and a channel frequency.

[0077] The identification message of the channel includes at least one of the location area number LAI, the cell number and the channel frequency, and may also include other identification information that can represent the channel. When searching for the setting value of the wireless link timeout, it can be done through the identification message of the channel, and will not cause the failure or error in obtaining the channel information; the setting value of the wireless link timeout corresponding to its identification message is extracted from the information of the currently used channel. It can be understood that it can also include multiple channels, and there are multiple channel frequencies as a channel frequency set, and the setting value of the wireless link timeout of each channel is obtained from the database through the location area number, cell number and channel frequency set.

[0078] By setting the channel identifier, for example, the channel identifier message includes at least one of the location area number, the cell number and the channel frequency, the accuracy of obtaining the setting value of the channel's wireless link timeout is improved, thereby improving the accuracy of wireless link failure judgment and ensuring the reliability of communication operations.

[0079] In one embodiment, reference Figure 7 , after the step of receiving the setting value of the wireless link timeout sent by the network, it also includes:

[0080] Step S01, when the setting value of the wireless link timeout corresponding to the identification information point cannot be obtained from the database, a wireless link failure judgment operation is performed according to the setting value of the wireless link timeout issued by the network;

[0081] Step S02: receiving a slow associated control channel message sent by the network, and when decoding of the slow associated control channel message fails, reducing a setting value of a radio link timeout according to a third step length.

[0082] The database maintains the setting value of the wireless link timeout of the channel, but not every channel is maintained. Some channels have always had good signal quality, or have not been saved or are channels of newly added cells, or the user has not been to the base station range of the cell before, so the database does not store the setting value of the wireless link timeout of the channel. When the setting value of the wireless link timeout corresponding to the identification information cannot be obtained from the database, when making a wireless link failure judgment, the wireless link failure judgment operation can only be performed according to the setting value of the wireless link timeout issued by the network, and the setting value of the wireless link timeout issued by the network is saved in the database, and a file of the setting value of the wireless link timeout of the channel is established, and a record is made for subsequent operation judgment.

[0083] Receive the SACCH message sent by the network, and when decoding fails, increase the set step size to the third step size, and reduce the setting value of the wireless link timeout according to the third step size. For example, the previously set step size is 1, and now it is adjusted to 2 or 3. Because there is no relatively small setting value of the wireless link timeout stored, when the timeout occurs, it is necessary to increase the adjustment amplitude, and quickly increase the reduction amplitude, so that the setting value of the wireless link timeout can be quickly reduced to 0; when the SACCH message fails to be parsed for 2 or 3 consecutive times, continue to increase the set step size, for example, adjust it to 4 or 5, so that it can be reduced to 0 more quickly, reduce the judgment time, abandon the channel with poor signal, and switch to the new channel with good signal to perform communication operations. The third step size can be the same as the second step size, or it can be different. For example, if the second step size is 2, the third step size can be 3, which is set according to the needs of setting in advance and reducing the amplitude.

[0084] When the setting value of the wireless link timeout of the current channel cannot be found from the database, this embodiment adopts a larger increase in the step size, reduces the number of intermediate judgments, and quickly reduces the setting value of the wireless link timeout to 0, thereby reducing the time spent on the current channel, and then quickly switching to other channels, ensuring the efficiency of communication operations.

[0085] In one embodiment, reference Figure 8 , the method further comprising:

[0086] Step S03, when the occupied storage space of the database reaches a threshold, determine the stored wireless link timeout setting values ​​that do not carry a modification mark; and perform a deletion action on the wireless link timeout setting values ​​that do not carry a modification mark from the database.

[0087] When the database storage space is full, the stored records need to be deleted. Some of the wireless link timeout setting values ​​stored in the data are issued by the network, and some are modified after being issued, that is, the reduced wireless link timeout setting value. Relatively speaking, the modified part is beneficial to the subsequent wireless link failure, and can quickly complete the judgment process and enter the new channel to perform communication operations. Therefore, when performing the deletion operation, delete the unmodified wireless link timeout setting value first, that is, delete the part in the database that does not carry the modification mark. This can save storage space and will not affect the subsequent communication operation to perform the judgment operation of the wireless link failure.

[0088] This embodiment first deletes the setting value of the wireless link timeout that does not carry a modification mark, retains the setting value of the wireless link timeout that has been modified, and retains the setting value of the wireless link timeout with a relatively lower value that is deleted. When performing a wireless link timeout judgment operation, the number of judgments and the judgment process can be saved, thereby saving time.

[0089] In another embodiment of the present application, when deleting records, the number of times the stored wireless link timeout setting value has been modified is obtained, and the setting value of the wireless link timeout with fewer modifications is deleted. In this way, the setting value of the wireless link timeout of the channel with more modifications indicates that the channel quality is poor. If it is deleted, it will affect the subsequent judgment of the wireless link timeout. The records with fewer modifications can be deleted. The signal quality of those channels is high, and SACCH message decoding failure is not likely to occur.

[0090] In one embodiment, reference Fig. 9 , the method further comprising:

[0091] Step S04, obtaining the number of times the channel reaches wireless link failure;

[0092] Step S05, determining a decreasing range of the setting value of the wireless link timeout according to the number of wireless link failures;

[0093] Step S06: reducing the setting value of the radio link timeout of the channel according to the decreasing amplitude, and performing the next radio link failure judgment operation according to the reduced setting value of the radio link timeout.

[0094] In this embodiment, the number of times the channel is judged to have failed in the wireless link is obtained. Because the same channel will be used by different users, its number of failures can be recorded, and even if it is used by the same user, there will be wireless link failures at different times. The number of failures can be used to know the signal quality of the channel, and a trend can be obtained, and then the reduction amplitude of the setting value of the wireless link timeout is adjusted. The greater the number of times, the greater the reduction amplitude, and the fewer the number of times, the smaller the reduction amplitude. The setting value of the wireless link timeout of the channel is adjusted according to the reduction amplitude, and the next wireless link failure judgment operation is performed according to the adjusted setting value of the wireless link timeout. For example, if the number of times is 2, the reduction amplitude is 2; the number of times is 3, the reduction amplitude is 3; the number of times is 4, the reduction amplitude is 4, etc.

[0095] Before determining the setting value of the wireless link timeout, this embodiment obtains the number of wireless link failures of the channel. The greater the number of failures, the greater the reduction in the setting value of the wireless link timeout after the SACCH message decoding fails. In this way, the setting value of the wireless link timeout can be quickly reduced to 0 depending on the quality of the channel, and the channel can be switched to a new channel to perform communication operations, saving time and improving efficiency.

[0096] To better describe the embodiment of the present application, the communication operation process includes:

[0097] Create a database to record the LAI, cell number, channel frequency (set) that needs to be corrected (the reason for adding "set" is that the channel allocated by the network to the UE may be a single-frequency channel or a frequency-hopping channel with multiple frequencies), and the RADIO_LINK_TIMEOUT value S0 to be used next time. At the same time, set the maximum number of storage records, and the initial database record is empty.

[0098] 2.2 Set a custom RADIO_LINK_TIMEOUT value N and "reduction step" step.

[0099] 2.3 When the UE obtains a new dedicated channel configured by the network and obtains the RADIO_LINK_TIMEOUT value issued by the network.

[0100] If the RADIO_LINK_TIMEOUT sent by the network is less than or equal to N, it means that the value of RADIO_LINK_TIMEOUT sent by the network is small enough and does not need to be optimized. Then, according to the algorithm specified by 3GPP (as described in 1.1), the initial S value is set to the RADIO_LINK_TIMEOUT value sent by the network and the S value is continued to be calculated.

[0101] If the current LAI, cell number, channel frequency (set) is consistent with the LAI, cell number, channel frequency (set) of a record in the database, it means that the network has changed the RADIO_LINK_TIMEOUT compared with the previous record. At this time, the record in the database needs to be deleted.

[0102] If the current LAI, cell number, channel frequency (set) is inconsistent with all records in the database, no operation is required for the time being.

[0103] If the RADIO_LINK_TIMEOUT sent by the network is greater than N.

[0104] If the current LAI, cell number, channel frequency (set) is consistent with the LAI, cell number, channel frequency (set) of a certain record in the database, select the smaller value between the RADIO_LINK_TIMEOUT sent by the network and S0 recorded in the database as the initial S value and continue to calculate the S value.

[0105] If the current LAI, cell number, channel frequency (set) is inconsistent with all records in the database, select the RADIO_LINK_TIMEOUT issued by the network as the initial S value and continue to calculate the S value.

[0106] c. If the frequency point (set) can be successfully changed to a new dedicated channel in the current dedicated channel (the method includes switching, channel allocation, frequency redefinition, etc., note that this is equivalent to returning to the situation 2.3) or the connection can be released normally in the current dedicated channel, it means that the current channel has become better. At this time, you need to check the database. If the database already has a record with the same LAI, cell number, and channel frequency point (set), delete the record.

[0107] d. If S=0 causes Radio Link Failure, the larger value of (this initial S value - Step) and N is set to S0, and this S0 and the current LAI, cell number, and channel frequency (set) are updated to the database. If the database already has the same record as the current LAI, cell number, and channel frequency (set), S0 is updated; if the database does not have the current LAI, cell number, and channel frequency (set) record, a new record is created to update the current LAI, cell number, channel frequency (set) and S0 (if the database records after the new creation have exceeded the maximum number of storage records, the earliest updated record is deleted).

[0108] In one embodiment, reference Fig.10 , a communication control method is proposed, the communication control method comprising the steps of:

[0109] Step S101, receiving a slow associated control channel message sent by the network;

[0110] Step S102, when decoding of the slow associated control channel message fails, performing a reduction operation of a setting value of a radio link timeout issued by the network according to a preset step size;

[0111] Step S103: When the setting value of the wireless link timeout sent by the network is reduced to 0, the setting value of the wireless link timeout sent by the network which is reduced by the second setting value is saved in the database.

[0112] The setting value of the wireless link timeout in this embodiment is a value issued by the network. When the judgment operation of wireless link failure is performed according to the setting value of the wireless link timeout, it is judged whether the received SACCH (Slow Associated Control Channel) message can be successfully decoded. If it can be successfully decoded, it means that there is no problem with the channel data transmission. If it cannot be decoded or the decoding fails, the setting value of the wireless link timeout needs to be reduced by 1, that is, the set step size is 10. As long as the SACCH message decoding fails, the setting value of the wireless link timeout is reduced by 1. If the setting value of the wireless link timeout is reduced to 0, it is determined that the wireless link has failed, and it is necessary to reopen other channels to complete the communication operation, abandon the data transmission of the channel of the current cell, and open the communication operation of the channel of another new cell. By continuously parsing the received SACCH message, the decoding fails continuously until the setting value of the wireless link timeout is reduced to 0, and the wireless link fails. When the current channel triggers a wireless link failure, that is, the signal and quality of the current channel are poor, the setting value of the wireless link timeout needs to be reduced, otherwise the previous setting value of the wireless link timeout will be used next time, which will waste time in judgment. Therefore, the standard setting value of the wireless link timeout issued by the network with the second setting value reduced is saved to the database as the setting value of the wireless link timeout when the channel is used next time. The second setting value can be different from the first setting value or the same, and can be set according to the needs set in advance; in this way, there will be a setting value of the wireless link timeout that is smaller than the setting value of the wireless link timeout in the database. When the channel is enabled to perform communication operations, the setting value of the wireless link timeout judgment will be reduced, and too much judgment time will not be wasted, so that the wireless link failure can be quickly judged. The second setting value can be 15 or 20, and it is modified according to the size of the setting value of the wireless link timeout. For example, if the setting value of the wireless link timeout is 60, the second setting value is 45, or the setting value of the wireless link timeout is 30, and the second setting value is 25, etc. The larger the setting value of the wireless link timeout is, the larger the second setting value is; the smaller the setting value of the wireless link timeout is, the smaller the second setting value is.

[0113] The embodiment of the present application adjusts the setting value of the wireless link timeout of the channel after a channel triggers a wireless link failure, reduces the setting value and saves it to the database, so that when performing subsequent communication operations on the channel, the initial value can be lowered when making a wireless link failure judgment. In this way, the judgment of the wireless link failure can be completed quickly, the judgment process is reduced, time is saved, and the efficiency of communication operations is improved.

[0114] In one embodiment, reference Fig.11 , after the step of reducing the setting value of the radio link timeout issued by the network according to the set step size when decoding the slow associated control channel message fails, it also includes:

[0115] Step S104: When the number of times the reduction operation is performed on the setting value of the wireless link timeout reaches the set number of times, the setting value of the wireless link timeout issued by the network is reduced according to the fourth step.

[0116] The set number of times can be 2 or 3 times, or it can be set to a larger value, for example, 5 or 6 times, according to the signal quality of the channel history. For example, the better the quality, the larger the number of times, and the worse the quality, the smaller the number of times. When the set number of times is reached, that is, when the number of failed SACCH message decoding reaches the set number of times, the step size of each reduction is increased to the fourth step size, for example, it is reduced by 1 before, and then reduced by 2 after the increase. The fourth step size is larger than the first step size, and can be the same as the second or third step size, or it can be different. The setting value of the wireless link timeout can be quickly reduced to 0 by increasing the fourth step size, and the judgment of the wireless link failure can be completed, the operation process can be accelerated, and the judgment of the wireless link failure can be quickly reached, which saves the judgment process, and a new channel can be selected in advance to perform communication operations, thereby improving the efficiency of communication.

[0125] The storage module 60 is used for saving the standard setting value of the wireless link timeout reduced by the first setting value to the database when the standard setting value of the wireless link timeout is reduced to 0.

[0127] Furthermore, the processing module 50 is further configured to reduce the standard setting value of the wireless link timeout according to a second step length when the number of reductions reaches a preset number of times, and the second step length is greater than the first step length.

[0128] Furthermore, the acquisition module 20 is used to determine the identification information of the currently used channel; obtain a setting value of the wireless link timeout corresponding to the identification information from a database, and the identification information includes at least one of a location area number, a cell number and a channel frequency.
