Detailed Description
In order to better understand the context of the present invention, the present invention first introduces the concept of a WLAN channel list. The list of WLAN channels is the radio channels that the wireless network should use in the IEEE802.11 protocol standard as specified by law; here, the IEEE802.11 protocol standard is set by the international Institute of Electrical and Electronic Engineering (IEEE) (or referred to as Wi-Fi). The 802.11 protocol working group has divided two independent frequency bands in the IEEE802.11 protocol standard, including: a 2.4GHz band and a 4.9/5.8GHz (which may be referred to as 5GHz) band; each frequency band is divided into a plurality of channels, and each country makes relevant laws and policies according to the requirements of the country to determine how to use the frequency bands. The 4.9/5.8GHz band may be referred to as a 5GHz band. Most countries use the 2.4GHz industrial, scientific, and medical (ISM) band, but the number of channels or bands supported by each country is different, as shown in fig. 1, channel1-11 is supported in the united states and channel1-13 is supported in japan. The use condition of the 5GHz ISM band in each country is relatively complex, as shown in fig. 2, channels 184 and 188 are supported in japan; channels 36, 40, 44, 48, 149, 153, 157, 161, 165 are supported only in the united states and other channels are defined as illegal or Dynamic Frequency Selection (DFS) channels; china only supports channels 149, 153, 157, 161, 165 and other channels are strictly forbidden. For more details, reference may be made to the provisions in the 802.11a/h/j/n protocol standard set forth by the IEEE.
As can be understood from these descriptions, channels supported by different countries are not the same, and thus, when a user moves from country to country, if the user is not familiar with the relevant laws and communication environments of each country, the wireless communication channel cannot be set according to the local laws in real time, which causes inconvenience in communication.
Here, since The third generation partnership project (3 GPP) defines a unique mobile country code for each country, a wireless communication network of each country has a unique mobile network identification based on this. The mobile network identification comprises: a mobile country code and a mobile network code; the mobile country code refers to a country to which the wireless communication network belongs, and the mobile network code refers to a network identifier of the wireless communication network in the country; that is, the mobile country codes of all wireless communication networks in each country are identical. Therefore, the corresponding Wi-Fi country code and the corresponding WLAN channel of the Wi-Fi country code can be set through the mobile country code.
Based on this, in various embodiments of the invention: monitoring the mobile country code of the current wireless network, and converting the mobile country code of the current wireless network into a corresponding first standard country code; and selecting a corresponding working channel according to the first standard country code.
The technical solution of the present invention is further described in detail by the accompanying drawings and the specific embodiments.
Example one
As shown in fig. 3, the method for adjusting a wireless communication channel provided in this embodiment mainly includes the following steps:

in the step, a mobile network is registered, the mobile country code of the current wireless network is monitored in real time, the mobile country code of the current network is obtained through a network finding process, and the mobile country code is converted into a corresponding first standard country code; specifically, the current wireless environment is scanned in full frequency, the system broadcast message of the cell to which the wireless environment belongs is read, and the mobile country code is acquired.
The converting the mobile country code of the current network into the corresponding first standard country code specifically includes:
translating the mobile country code to the first standard country code according to a protocol standard of a wireless network.
In practice, the mobile country code may be translated into the first standard country code according to the IEEE802.11 protocol standard established by the IEEE. Wherein the first standard country code may be: Wi-Fi country code currently set in wireless networks.

Step 302, selecting a corresponding working channel according to the first standard country code;
in this step, selecting a corresponding working channel according to the first standard country code includes:
and when the first standard country code is determined to be inconsistent with a set second standard country code, switching a second WLAN channel corresponding to the second standard country code to a first WLAN channel corresponding to the first standard country code. Wherein, when the first standard country code is a Wi-Fi country code, the second standard country code may be: Wi-Fi country code set in a wireless network before roaming. The first WLAN channel may be obtained by querying a first standard country code in a WLAN profile; the second WLAN channel may be obtained by querying a second standard country code in a WLAN profile.

Wherein, the WLAN channel is a basic configuration parameter in the WLAN; the configuration parameters of the WLAN include: a Service Set Identifier (SSID), a key, a Media Access Control (MAC) address, etc.
When switching is carried out, a first WLAN channel parameter is set, and the switched first WLAN channel parameter is controlled to take effect, so that the terminal can carry out normal communication.
Additionally, when it is determined that the first standard country code is not consistent with a second standard country code, and it is determined that the first WLAN channel is consistent with the second WLAN channel, the method further comprises: the second WLAN channel is kept unchanged.
Here, the WLAN channel described in this embodiment may be a Wi-Fi channel.
