Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application , rather than all embodiments.
Example
Please refer to fig. 1, which shows flowcharts of the base station handover method provided in the present application, and the method may include the following steps:
and step S11, when the signal intensity of the base station currently connected with the mobile terminal is smaller than the scanning threshold, selecting base stations with the signal intensity larger than the switching threshold from the base stations adjacent to the base station currently connected with the mobile terminal as the base stations to be connected.
When the signal strength of the base station to which the mobile terminal is currently connected is smaller than the scanning threshold, the communication quality of the mobile terminal is reduced or even normal communication cannot be performed, so that the mobile terminal needs to perform base station switching to ensure the communication quality.
In this embodiment, the switching threshold is greater than the scanning threshold. It should be noted that the reason why the switching threshold is set to be greater than the scanning threshold is to ensure that the signal strength of the base station to which the mobile terminal is to be connected is good enough, so that the mobile terminal can be switched to the base station whose signal strength is greater than the scanning threshold when the signal strength of the base station to which the mobile terminal is currently connected is less than the scanning threshold, and the mobile terminal is prevented from still communicating with the base station whose signal strength is weak, thereby ensuring that the mobile terminal can perform better communication.
Step S12: and continuously scanning the signal intensity of the base station to be connected to obtain a plurality of scanning results.
In this embodiment, the scanning result is the signal strength of the to-be-connected base station obtained by scanning.
Step S13: and recording the variation trend of the signal intensity of the base station to be connected by using a plurality of scanning results.
Step S14: and if the change trend of the signal intensity of the base station to be connected is an ascending trend, switching from the base station currently connected with the mobile terminal to the base station to be connected.
Step S15: and if the change trend of the signal intensity of the base station to be connected is a descending trend, judging whether an unselected base station exists in the base stations adjacent to the base station currently connected with the mobile terminal.
If so, go to step S16, otherwise, go to step S17.
If there is an unselected base station in the base stations adjacent to the base station currently connected to the mobile terminal, the step S16 is executed, and if there is no unselected base station in the base stations adjacent to the base station currently connected to the mobile terminal, it indicates that the mobile terminal has scanned all the base stations adjacent to the base station currently connected to the mobile terminal, and after scanning all the base stations adjacent to the base station currently connected to the mobile terminal, the trend of the change of the signal strength of the last scanned base stations is still a downward trend, the step S17 is executed.
Step S16, reselecting base stations with signal intensity larger than the switching threshold value from the base stations adjacent to the base station currently connected with the mobile terminal as the base stations to be connected, and returning to execute the step S12.
Step S17: and maintaining the connection with the base station currently connected with the mobile terminal or switching from the base station currently connected with the mobile terminal to the base station to be connected.
In the application, when the signal strength of the base station to which the mobile terminal is currently connected is smaller than the scanning threshold, the base station is switched to the neighboring base station with better signal strength immediately without searching neighboring base stations with better signal strength, base stations with signal strength larger than the switching threshold are selected from the base stations neighboring the base station to which the mobile terminal is currently connected as the base stations to be connected, the signal strength of the base stations to be connected is continuously scanned, the change trend of the signal strength of the base stations to be connected is recorded by using a plurality of scanning results, whether the base stations are switched is determined according to the change trend of the signal strength of the base stations to be connected, the mobile terminal is ensured to be switched to the neighboring base stations which are relatively stable, the probability of frequent switching of the mobile terminal is reduced, and the communication quality of the mobile terminal is improved.
Certainly, the signal strength of each base station in the overlapping coverage area with weak signal strength is more unstable, and the mobile terminal frequently switches the base station in the overlapping coverage area with weak signal strength, so that the method provided by the application has more obvious advantages, and the base station is switched after the change trend of the base station is determined, thereby avoiding the frequent switching of the mobile terminal, and further improving the communication quality of the mobile terminal in the overlapping coverage area with weak signal strength.
The process from step S11 to step S17 will now be described by way of example, where, for example, the base station to which the mobile terminal a is currently connected is base station 1, the base stations adjacent to base station 1 are base stations 2 and 3, respectively, and the mobile terminal a is located in the signal coverage overlapping area of base stations 1, 2 and 3, as shown in fig. 2. When the mobile terminal a is gradually far from the base station 1, and the signal intensity of the base station 1 is scanned to be less than the scanning threshold value, the base station 2 with the signal intensity greater than the handover threshold value is selected from the base stations 2 and 3 as a base station to be connected, the signal intensity of the base station 2 is continuously scanned to obtain a plurality of scanning results, and the change trend of the signal intensity of the base station 2 is recorded by using a plurality of scanning structures, as shown in fig. 3, the change trend of the signal intensity of the base station 2 is a descending trend, the base station 3 with the signal intensity greater than the handover threshold value is reselected as a base station to be connected, the signal intensity of the base station 3 is continuously scanned to obtain a plurality of scanning results, and the change trend of the signal intensity of the base station 3 is recorded by using a plurality of scanning structures, as shown in fig. 3, since the change trend of the signal intensity of the base station 3 is an ascending trend, the mobile terminal, and frequent switching of the mobile terminal to other base stations after the mobile terminal is switched to the base station 3 is avoided, and the communication quality is improved.
In this embodiment, in step S11, base stations with signal strengths greater than the handover threshold are selected from the base stations adjacent to the base station to which the mobile terminal is currently connected, and the process of selecting the base stations with signal strengths greater than the handover threshold and with the highest priority as the base stations to be connected may specifically be that base stations with signal strengths greater than the handover threshold are selected from the base stations adjacent to the base station to which the mobile terminal is currently connected as the base stations to be connected.
In step S16, reselecting base stations with signal strength greater than the handover threshold from the base stations neighboring the base station to which the mobile terminal is currently connected, and using the reselected base stations as the base stations to be connected, specifically, reselecting base stations with signal strength greater than the handover threshold and highest priority from the base stations neighboring the base station to which the mobile terminal is currently connected, and using the reselected base stations as the base stations to be connected.
Step S12 may be, but not limited to, continuously scanning the signal strength of the base station to be connected for more than 3 times to obtain more than 3 scanning results.
The signal strength of the base station to be connected is continuously scanned for more than 3 times, and more than 3 scanning results can be obtained specifically but not limited to: and continuously scanning the signal intensity of the base station to be connected for 20 times to obtain 20 scanning results.
The signal strength of the base station to be connected is continuously scanned for more than 3 times, and more than 3 scanning results can be obtained specifically but not limited to: and continuously scanning the signal intensity of the base station to be connected for 25 times to obtain 25 scanning results.
The signal strength of the base station to be connected is continuously scanned for more than 3 times, and more than 3 scanning results can be obtained specifically but not limited to: and continuously scanning the signal intensity of the base station to be connected for 30 times to obtain 30 scanning results.
The more times of scanning the signal intensity of the base station to be connected, the more accurate the recorded change trend of the signal intensity of the base station to be connected. However, it is also necessary to set an upper limit value for the number of scans to avoid an excessive number of scans.
