detailed description

In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Please refer to FIG. 1 . FIG. 1 is a flow chart of a preferred embodiment of the mobile terminal-based frequency band switching control method of the present invention. As shown in Figure 1, a mobile terminal-based frequency band switching control method provided by an embodiment of the present invention includes the following steps:

S100, setting a counter to record the number of times of switching between the high and low frequency antennas;

The mobile terminal transmits and receives the wireless battery through the antenna; at present, the mobile terminal often supports multiple radio frequency bands, some of these frequency bands (such as LTE BAND39) are relatively high, and some frequency bands (such as GSM850) are relatively low. More preferably, one kind of antenna is used for the high frequency band and another kind of antenna is used for the low frequency band in the mobile terminal. As shown in Figure 2, the first antenna is more suitable for sending and receiving high-frequency radio waves, and the second antenna is more suitable for sending and receiving low-frequency radio waves, which can achieve the best performance.

However, in the actual use of mobile terminals, it is occasionally encountered that the mobile terminal is at the junction of high and low frequencies. At the junction of coverage, the signals of LTE BAND39 and GSM850 are not very strong), at this time, the mobile terminal will often switch between high and low frequencies, and the antenna will also change frequently, resulting in radio wave reception and transmission efficiency Low.

Therefore, in the present invention, a counter is preset to record the number of switching times between the high and low frequency antennas. Specifically, add 1 to the counter when it is detected that the antenna used by the mobile terminal is switched between an antenna for transmitting and receiving electromagnetic wave signals at a high frequency and an antenna for transmitting and receiving electromagnetic wave signals at a low frequency; Add 1 to the counter when the antenna for transmitting and receiving electromagnetic wave signals at high frequency is switched to the antenna for transmitting and receiving electromagnetic wave signals at low frequency. Increment the counter by 1 for the antenna.

S200. Detect the growth value of the counter at each second time interval in the most recent first time period, and prohibit antenna switching if the growth values of the counters all exceed a threshold.

The first time period is 10 seconds. For example, the latest 10 seconds are detected, and the increment value of the counter at each second interval is detected. If all of them exceed the threshold value, antenna switching is prohibited.

In the embodiment of the present invention, preferably, the threshold is 30.

Specifically, step S20 includes:

S21 starts the timer, obtains the value of the counter every 1 second, and subtracts this value from the value of the counter obtained in the last second to obtain the growth value of the counter in this second;

S22 acquires the counter growth value in each second of the last 10 seconds, and judges whether they all exceed the threshold;

If S23 is yes, antenna switching is prohibited.

Inventor: For example, the increment value of the counter in each second obtained in the last 10 seconds is 31, 32, 32, 35, 55, 77, 32, 32, 31, 38, because they all exceed the threshold 30, so it is judged in S23 as Yes, then disable antenna switching. For example, the counter growth values obtained in each second in the last 10 seconds are 31, 25, 32, 32, 35, 55, 77, 32, 32, 38, because there is a 25 that does not exceed the threshold 30, so it is determined in S23 No, then the state of allowing antenna switching remains.

Wherein, the prohibition of antenna switching means not switching antennas when the mobile terminal switches from high frequency to low frequency or from low frequency to high frequency.

S300. Detect the growth value of the counter at each second time interval in the latest second time period, and allow antenna switching if none of them exceeds the threshold.

Preferably, the threshold in this step S300 is 30 the same as the threshold in step S200. Of course, other embodiments may be different, but the threshold in step S300R needs to be less than or equal to the threshold mentioned in S200), for example, the threshold is 25.

For example, the last 10 seconds are detected, and the increment value of the counter at each second time interval is detected, and if none exceeds the threshold, antenna switching is allowed.

Specifically, step S30 includes:

S31 starts the timer, obtains the value of the counter every 1 second, and subtracts this value from the value of the counter obtained in the last second to obtain the growth value of the counter in this second;

S32 obtains the counter growth value in each second of the last 10 seconds, and judges whether they are all less than or equal to the threshold;

If yes in S33, antenna switching is allowed.

For example, the increment value of the counter in each second obtained in the last 10 seconds is 21, 21, 22, 22, 15, 17, 22, 12, 21, 18, because none of them has a threshold of 25, and it is judged as yes in S33, and then the antenna is allowed switch. For example, the counter growth values obtained in each second in the last 10 seconds are 21, 21, 22, 22, 15, 17, 29, 12, 21, 18, because 29 exceeds the threshold value 25, it is judged as No in S33, and then it remains State where antenna switching is disabled.

Wherein, the allowing antenna switching is to switch the antenna when the mobile terminal switches from high frequency to low frequency or from low frequency to high frequency.

It can be seen from the above that the embodiment of the present invention provides a mobile terminal-based frequency band switching control method. The present invention provides a mobile terminal high-low frequency switching control method, which aims to solve the problem of frequent switching between high-frequency and low-frequency mobile terminals.
