Referring to fig. 1, an embodiment of the present invention provides a network selection method, including:
s1, acquiring a trigger instruction for selecting a network cell;
s2, respectively acquiring first call dropping parameters of each first network cell capable of identifying the network signal currently according to the trigger instruction; the first drop call parameter refers to the proportion of drop call times when the mobile terminal is resided in a specified first network cell to total call times when the mobile terminal is resided in the specified first network cell;
s3, selecting a first network cell to camp on from the first network cells whose first drop parameter is lower than the first preset threshold according to a first preset rule.
In this embodiment, as described in step S1, the network cell is an area covered by a base station or a part of a base station in the cellular mobile communication system, and the mobile terminal can reliably communicate with the base station through a wireless channel in this area. Mobile terminals such as mobile phones are often in a certain area, and a plurality of network cells can be selected. The selecting network cell is a process that the mobile terminal selects a certain network cell from a plurality of first network cells to camp on. The triggering instruction is used for triggering the selection of a certain network cell from a plurality of first network cells for residing. Under normal conditions, when a mobile terminal such as a mobile phone is restarted and is re-networked from an off-network state such as a flight state, a trigger instruction for acquiring a selected network cell is generated; in addition, a trigger event can be preset, when the trigger event is met, a trigger instruction for selecting the network cell is generated, and the mobile terminal can actively select the network cell according to the actual use experience of the user through the setting of the trigger event.
As described in step S2, the first network cell is a network cell in which the mobile terminal can identify a network signal in a certain area, and the mobile terminal can select one network cell from a plurality of first network cells to camp on. The call drop refers to that the user abnormally ends in the call process, for example, the call abnormally ends due to the base station signal coverage edge, adjacent channel interference, channel blockage and the like. The user normally hangs up or is hung up, no one answers and other situations in the conversation process belong to normal ending and do not belong to call drop. After the call is ended, the mobile terminal may obtain a Cause value (Cause value) of the end of the call from the bottom layer, where the Cause value is classified into classes 000, 001, 010, 011, 100, 101, 110, and 111, where the classes of 000 and 001 correspond to the end of the call caused by a normal event, and the classes of the other classes correspond to the end of the call caused by a dropped call. For example, after the call is ended, if the value of Cause value obtained by the mobile terminal when the call is ended is 000, the call is ended due to normal reasons; and if the Cause value obtained after the call is ended is 100, judging that the call is ended due to the call drop. The first drop call parameter refers to a ratio of drop call times when the mobile terminal is camped on a network cell to total call times when the mobile terminal is camped on the network cell. For example, in a certain area, there are three first network cells A, B and C, and when the mobile terminal is connected to network cell a in the past use process of the user, a total of 50 calls are made, and the number of calls ended due to a call drop is 6, the first call drop parameter is 12%; when the mobile terminal is connected to the network cell B, the total number of calls is 50, and the number of calls ended due to call drop is 4, so that the first call drop parameter is 8%; when the mobile terminal is connected to the network cell C, 50 calls are performed in total, and the number of calls ended due to call drop is 2, so that the first call drop parameter is 4%; after the triggering instruction for selecting the network cell is obtained, the mobile terminal obtains that the first drop call parameter of the network cell A is 12%, the first drop call parameter of the network cell B is 8% and the first drop call parameter of the network cell C is 4%.
As described in the above step S3, the first preset threshold may be determined according to the user' S requirement and the usage environment, and may be set to 10%, 20%, or the like. When the number of the dropped calls is lower than the first preset threshold, the call experience of the user is not affected, or the number of the dropped calls is still within the acceptable range of the user. The mobile terminal resides in the network cell with the first drop call parameter lower than the first preset threshold. If the first drop call parameter of a plurality of network cells is lower than the first preset threshold value, the mobile terminal can select one network cell from the plurality of network cells to reside according to the current network selection preference rule; the mobile terminal may also use other preset rules to camp on from the preferred one of the plurality of network cells. And if the number of the network cells of which the first drop call parameter is lower than the first preset threshold value is zero, selecting the network cell which resides in the network cell with the lowest first drop call parameter.
In the network selection method of this embodiment, the mobile terminal triggers and acquires the first call drop parameter of each first network cell by acquiring a trigger instruction for selecting the network cell, so that the mobile terminal can actively select the network cell according to the call drop condition of the call; and selecting the resident first network cell from the first network cells with the first call drop parameters lower than the first preset threshold according to a preset rule, so that the mobile terminal can select to be connected to the network cells with less call drops, and the call experience of the user is improved.
Referring to fig. 2, in an embodiment, the step S3 of selecting a camped first network cell according to a first preset rule from among the first network cells whose first drop parameter is lower than the first preset threshold includes:
s301, if the number of the first network cells of which the first drop call parameters are lower than the first preset threshold is more than or equal to 2, obtaining second drop call parameters of each second network cell of which the first drop call parameters are lower than the first preset threshold; the second call drop parameter refers to the number of times of calls between two adjacent call drops closest to the current time when the mobile terminal resides in a specified second network cell;
s302, selecting the second network cell with the largest second drop call parameter.
In this embodiment, as described in steps S301 to S302, the second network cell refers to a first network cell whose first drop parameter is lower than the first preset threshold, and the second drop parameter refers to the number of times of calls between two adjacent drops closest to the current time when the mobile terminal resides in one network cell. When the second drop call parameter is smaller, the number of calls between two nearest adjacent drop calls is smaller, the drop calls occur frequently, and the call performance of the network cell tends to be poor. On the contrary, the larger the second call drop parameter is, the larger the number of times of calls between two nearest adjacent call drops is, the less frequent the call drops occur, and the call performance of the network cell is stable or tends to be better. For example, for the first network cells A, B and C in the above example, the first drop call parameter is set to 10%, there are 2 second network cells below the first preset threshold, which are network cell B (the first drop call parameter is 8%) and network cell C (the first drop call parameter is 4%); further acquiring second call drop parameters of the network cell B and the network cell C, and when the mobile terminal resides in the network cell B, assuming that the call drop times nearest to the current time are recorded as the 91 st call, and the call drop times nearest to the current time are recorded as the 70 th call, the call times between the last two call drops of the network cell B are 20 times, namely the second call drop parameters of the network cell B are 20 times; similarly, a second drop call parameter of the network cell C is obtained, and the second drop call parameter of the network cell C is assumed to be 10 times; then camp on network cell B is selected.
Referring to fig. 3, in an embodiment, before the step S1 of obtaining the trigger instruction for selecting the network cell, the method includes:
s01, acquiring the current position address;
and S02, if the current position address is included in a preset address list, generating the trigger instruction, wherein the preset address list stores an address preset by a user.
In this embodiment, as described in the above step S01, the current location address refers to an address of a current location of the mobile terminal, and specifically, the positioning unit in the mobile terminal may position the current location address of the mobile terminal, where the positioning unit includes one or more of the commonly used four satellite navigation systems GPS, GLONASS (GLONASS), Galileo (Galileo), and BeiDou (BeiDou).
As described in step S02, the preset address list stores addresses preset by the user, and places where calls frequently occur are generally fixed for the user, such as an office, a home, or other specific addresses, and the user can store the addresses where calls frequently occur in the preset address list. Taking an office as an example for illustration, when a user is at the office, the first network cells which can be accessed by the mobile terminal currently are relatively fixed and generally do not change too much, and the times of calls occurring at the office are relatively large and continuously increase along with the time, and the statistics of the first call drop parameters of the first network cells can be continuously carried out; and if the address is the address which some users pass through occasionally, the call drop rate of the first network cell in the area does not need to be counted. And if the user reaches the address in the preset address list, generating the trigger instruction, and triggering the mobile terminal to reselect the first network cell according to the method of the embodiment of the invention.
Referring to fig. 4, in an embodiment, before the step S1 of obtaining the trigger instruction for selecting the network cell, the method includes:
s03, acquiring the current time;
and S04, if the current time is included in a preset time period, generating the trigger instruction.
In this embodiment, as described in steps S03 to S04, the current time may be obtained by a time module built in the mobile terminal, and the preset time period refers to a specific time period preset by the user. In the preset time period, the call demand of the user is higher, and the user needs to be connected to a network cell with less dropped calls; or in the preset time period, the number of users accessed to the first network cell is large, the generated call interference is large, the frequency of call drop is high, and the network cell with less call drop needs to be selected for residence. Therefore, when the mobile terminal detects that the current time is included in the preset time period, a trigger instruction is generated to trigger the mobile terminal to reselect the first network cell according to the method of the embodiment of the invention. And when the user is not in the preset time interval, the requirement of the user for communication is less, and the network selection can be carried out according to the current network selection rule.
Referring to fig. 4, in an embodiment, after the step S3 of selecting a camped first network cell according to a first preset rule from among the first network cells whose first drop parameter is lower than the first preset threshold, the method includes:
s41, after each call is finished, judging whether the reason for finishing the call is a call drop;
s51, if the call is a dropped call, recording the time when the call is dropped, and adding the time into a preset list;
and S61, calculating the preset time interval according to a second preset rule according to each moment recorded in the preset list.
In this embodiment, as described in step S41, the above determining whether the reason for the call end is the call drop may be that after the call is ended, the mobile terminal obtains a value (Cause) of the call end from the bottom layer, where the Cause value is classified into the classes 000, 001, 010, 011, 100, 101, 110, and 111, where the classes of 000 and 001 correspond to the call end caused by the normal event, and the classes correspond to the call end caused by the call drop.
As stated in step S51, the time when the call drop occurs refers to the time when the user ends the call due to the call drop during the call, such as 11:45, 12:30, 18:15, etc., for example, the end time of the call is recorded. The preset list is used for storing the time when the call drop occurs, and the time when the call drop occurs is added into the preset list every time the call drop occurs.
In the step S61, the second preset rule specifically means that, according to each time recorded in the preset list, a time period corresponding to the time is obtained, for example, a time period that 11:45 belongs to 11 o 'clock to 12 o' clock, a time period that 12:30 belongs to 12 o 'clock to 13 o' clock, and a time period that 18:15 belongs to 18 o 'clock to 19 o' clock; counting the call drop times of each time period, for example, the call drop times in the time period from 11 points to 12 points are 5 times, the call drop times in the time period from 12 points to 13 points are 1 time, and the call drop times in the time period from 18 points to 19 points are 0 time; comparing the call drop times of each time interval with a preset time threshold, if the call drop times exceed the preset time threshold, adding the corresponding time interval exceeding the preset time threshold into the preset time interval, for example, if the preset time threshold is 3 times, adding the time intervals of 11 to 12 points into the preset time interval.
Referring to fig. 5, in an embodiment, after the step S3 of selecting a camped first network cell according to a first preset rule from among the first network cells whose first drop parameter is lower than the first preset threshold, the method includes:
s42, after each call is finished, judging whether the reason for finishing the call is a call drop or not, and increasing the total call times of the first network cell which is resided at present by 1 time;
s52, if the call is a call drop, increasing the number of call drops of the first network cell by 1 time;
s62, calculating the ratio of the dropped call times of the first network cell to the total call times of the first network cell, and assigning the ratio to a first dropped call parameter of the first network cell.
In this embodiment, as described in the above steps S42 to S62, after each call is ended, the number of times a of the call corresponding to the currently camped first network cell is increased by 1 time; judging whether the call termination is caused by a call drop, wherein the specific judgment method is that the mobile terminal obtains a Cause value (Cause value) of the call termination from a bottom layer after the call termination, the Cause value is divided into grades of 000, 001, 010, 011, 100, 101, 110 and 111, the grades of 000 and 001 correspond to the call termination caused by a normal event, and the grades of other grades correspond to the call termination caused by the call drop; if the call is caused by the call drop, the number b of call drops corresponding to the first network cell which is resided at present is increased by 1 time; and if the call is ended due to the normal reason, keeping the call drop times b corresponding to the first network cell which is resided currently unchanged. And calculating the updated ratio of b to a to obtain an updated value of the first drop call parameter of the first network cell which currently resides.
In an embodiment, after the step S62 of calculating the ratio of the dropped call times of the first network cell to the total call times of the first network cell, and assigning the ratio to the first dropped call parameter of the first network cell, the method further includes:
s72, if the first drop call parameter of the first network cell is higher than a second preset threshold, generating the trigger instruction; wherein the second preset threshold is greater than or equal to the first preset threshold.
In this embodiment, as described in the above step S72, the second preset threshold may be determined according to the user requirement and the use environment, for example, set to be 15%, 20%, 30%, and the like, and when the second preset threshold is higher than the second preset threshold, the call experience of the user is very poor, and the user is already unable to accept the call experience. And if the call is ended due to call drop and the first call drop parameter of the first network cell after the call drop is higher than the second preset threshold, generating a trigger instruction and triggering the mobile terminal to reselect the network cell. The second preset threshold is greater than or equal to the first preset threshold. If the second preset threshold is smaller than the first preset threshold, the mobile terminal may enter into a loop connecting to the network cell a, triggering the network cell to be reselected, and accessing the network cell a again. Setting the second preset threshold to be greater than or equal to the first preset threshold can avoid falling into such repeated reselection.
Referring to fig. 5, in an embodiment, after the step S1 of obtaining the trigger instruction for selecting the network cell, the method further includes:
s11, respectively obtaining the current signal strength value of each first network cell and the historical signal strength value recorded at the moment closest to the current time;
s12, calculating the signal strength amplification of each first network cell according to each current signal strength value and each corresponding historical signal strength value;
and S13, resetting the first drop call parameter of the first network cell with the signal strength amplification exceeding a third preset threshold value to be zero.
In this embodiment, as described in step S11, the current signal strength value refers to a signal strength value of the current time of each first network cell. The historical signal strength value refers to a signal strength value recorded at a time closest to the current time, that is, a signal strength value recorded last time and stored in the mobile terminal.
As described in step S12, the signal strength of the first network cell may be increased by subtracting the corresponding current signal strength value from the corresponding historical signal strength value for a certain first network cell.
As described in the above step S13, the above third preset threshold may be determined according to the user requirement and the usage environment. If the value is higher than the third preset threshold, it indicates that the signal strength of the base station corresponding to the first network cell is greatly increased, and it is possible that the base station is repaired, or the reason for originally weakening the base station signal disappears to cause the signal strength of the base station to recover, and at this time, the factor originally causing a high call drop rate also partially disappears, so that it is necessary to count the call drop rate again. Resetting the first call drop parameter to zero, namely clearing the total call times when the mobile terminal resides in the network cell and clearing the call drop times when the mobile terminal resides in the network cell.
