The mobile terminal starts a wireless local area network technology for wireless hotspot application, taking 2.4G as an example, the operating frequency band is 2.4GHz to 2.4835GHz, and these frequency bands are divided into 14 channels (domestic 1 to 13 channels, 22MHz bandwidth), as shown in fig. 1, in general, the available channels overlap in frequency, and there are only 3 non-overlapping channels in a section of frequency interval (2.401 to 2.488 GHz): 1,6, 11 (or 2, 7, 12; or 3, 8, 13; or 4, 9, 14).
In a daily environment, a large number of WLAN networks exist, at this time, the problem of co-frequency or adjacent-frequency interference caused by that a plurality of WLAN networks work in the same channel occurs, and other 2.4G wireless interference signals also exist in the environment, which affects the user internet experience. At present, when a mobile terminal opens a wireless hotspot, a wireless interference signal around the mobile terminal is acquired through a WLAN antenna, and a channel with minimum interference is selected according to the interference degree of the channel. Since the surrounding network environment is constantly changing, the interference of the channel becomes more and more serious with the increase of surrounding wireless devices or the occurrence of other interference signals, which may cause the unstable wireless hotspot or even the connection failure. At this time, the WLAN antenna is required to dynamically scan the interference level of the surrounding channels and reselect the channel with the minimum interference. In the process of scanning all channels through the WLAN antenna, the rate of the wireless hot spot is affected, the transmission quality is degraded, and the throughput is affected.
The invention aims to utilize the existing Wireless Wide Area Network (WWAN) antenna (such as a 2G high-frequency antenna, a 3G high-frequency antenna, an LTE high-frequency antenna or a 5G high-frequency antenna) of a mobile terminal, so that when the mobile terminal starts a wireless hotspot, an interference signal of a peripheral preset frequency band (such as a frequency range of 2.4 GHz-2.4835 GHz) can be acquired through the WWAN antenna, and the mobile terminal selects an optimal channel to start the hotspot. In the process of using the wireless hotspot of the mobile terminal, the WWAN antenna dynamically detects an interference signal of a peripheral predetermined frequency band (for example, the frequency range is 2.4 GHz-2.4835 GHz), and when the interference signal meets a certain condition in a current channel, for example, the interference signal is in the frequency range of the current channel, the mobile terminal switches to another channel, wherein the interference strength of the interference signal to the other channel is smaller than the interference strength of the interference signal to the current channel, so that the interference of the peripheral wireless signal can be avoided, and the stability of the wireless hotspot is ensured.
Specifically, the terminal device provided in the embodiment of the present application includes an architecture as shown in fig. 2, that is, a wireless communication module of the mobile terminal includes a WLAN module and a mobile cellular network module, specifically, the WLAN module includes a WLAN antenna and a WLAN access; the mobile cellular network module comprises an LTE high-frequency antenna and a receiving detection circuit, wherein the WLAN access and the receiving detection circuit are connected with the central processing unit CPU. The specific division of labor is as follows: the WLAN antenna and the WLAN access are responsible for receiving and transmitting WLAN signals, and serve as wireless Access Points (APs) when the wireless hotspot is started; the LTE high-frequency antenna is responsible for receiving an interference signal in a predetermined frequency band (for example, a frequency band of 2.4GHz to 2.4835 GHz), transmitting detailed information of the interference signal to the CPU through the reception detection circuit, and the CPU determines to implement the channel control method of the WLAN antenna provided in the embodiment of the present application. Of course, in the embodiments of the present application, the WWAN antenna is mainly described by taking an LTE high frequency antenna as an example, and antennas in other forms should also be within the scope of the present application.
Based on the foregoing terminal device, an embodiment of the present application provides a channel control method for a WLAN antenna, which is applied to a mobile terminal, where the mobile terminal includes a WWAN antenna and a WLAN antenna, and as shown in fig. 3, the method includes the following steps:

102. And determining a channel used by the mobile terminal for transmitting data on the WLAN antenna according to the interference signal on a preset frequency band.
In the above scheme, because the interference signal received by the WWAN antenna at the predetermined frequency band is adopted, compared with the prior art, the method avoids the situation that the surrounding wireless interference signal is obtained through the WLAN antenna, and simultaneously avoids the situation that the interference degree of all channels is dynamically scanned through the WLAN antenna, and then the channel with the minimum interference is reselected, so that the reduction of the transmission quality of the wireless hotspot caused by the interference signal detected by the WLAN antenna can be avoided; meanwhile, the antenna utilization rate of the mobile terminal is improved by adopting the WWAN antenna to detect the interference signal.
In view of the difference between the control methods before and after the mobile terminal opens the hot spot, referring to fig. 4, an embodiment of the present application provides a channel control method for a WLAN antenna, which is applied to a mobile terminal, where the mobile terminal includes a WWAN antenna and a WLAN antenna, and includes the following steps:

202. And detecting an interference signal received by the WWAN antenna at a predetermined frequency band, wherein the predetermined frequency band is a frequency band used by the mobile terminal for transmitting data on the WLAN antenna.
203. And if the WWAN antenna is determined not to detect the interference signal in the preset frequency band, randomly selecting a channel for the mobile terminal to transmit data on the WLAN antenna in the preset frequency band.
When a hotspot opening instruction is acquired, the mobile terminal has a distribution network process, at this time, the LTE high-frequency antenna automatically detects an interference signal in a range of 2.4GHz to 2.4835GHz of a peripheral predetermined frequency band, and transmits information of the interference signal to a CPU of the mobile terminal through a receiving detection circuit, and the CPU of the mobile terminal selects a channel which is used by the peripheral wireless network least (i.e., has the lowest interference intensity) according to a 2.4G frequency band channel scheme, in combination with the central frequency of a innovation channel shown in the following table 1 (802.11 b bandwidth 22mhz,802.11g/n bandwidth 20 MHz) in fig. 1, and randomly allocates the channel if the interference signal is not detected.
TABLE 1
204. And if the WWAN antenna detects the interference signal in the preset frequency band, selecting a channel with the interference strength smaller than or equal to the preset value as a channel for the mobile terminal to transmit data on the WLAN antenna according to the interference signal in the preset frequency band.
An optimal channel with an interference strength less than or equal to a predetermined value is selected as a channel for the mobile terminal to transmit data on the WLAN antenna in step 204, for example, a channel with minimum interference is selected, or a channel without interference is selected.
Thus, after the hot spot is turned on, the mobile terminal transmits data on the WLAN antenna using the channel selected through step 203 or 204 as the channel, e.g., the first channel, on which the mobile terminal transmits data on the WLAN antenna. Then, when the mobile terminal determines that the mobile terminal uses the first channel for transmitting data on the WLAN antenna after the hotspot is opened, the method further includes the following steps:
205. and detecting an interference signal received by the WWAN antenna at a predetermined frequency band, wherein the predetermined frequency band is a frequency band used by the mobile terminal for transmitting data on the WLAN antenna.

Therefore, in the hot spot use process, the LTE high-frequency antenna dynamically monitors the interference signal in the range of 2.4 GHz-2.4835 GHz of the surrounding preset frequency band, transmits the detailed information of the interference signal to the CPU through the receiving detection circuit, and when the interference signal meets a certain condition in the current channel, for example, the interference signal is in the frequency range of the current channel, the mobile terminal is switched to other channels, wherein the interference intensity of the interference signal to the other channels is smaller than the interference intensity of the interference signal to the current channel. If the interference signal frequency is not in the current channel frequency range or no wireless interference signal is detected, the current channel is continuously used, so that the stability of the network when the user uses the hotspot can be ensured.
