Embodiment
In order to understand content of the present invention, the present invention first introduces the concept of WLAN channel list.WLAN channel list is the wireless channel that in law defined IEEE802.11 consensus standard, wireless network should use; Here, described IEEE802.11 consensus standard is (or being called Wi-Fi) that International Power electronic engineering association (IEEE, InstituteofElectricalandElectronicsEngineers) is formulated.802.11 protocols work groups have divided two independently frequency ranges in IEEE802.11 consensus standard, comprising: 2.4GHz frequency range and 4.9/5.8GHz (can be called 5GHz) frequency range; Again each frequency range is divided into some channels, according to this country, each country requires formulation relevant law and policy are to determine how to use these frequency ranges.Wherein, 4.9/5.8GHz frequency range can be called 5GHz frequency range.That overwhelming majority of countries adopts is the industry of 2.4GHz, science, medical science (ISM, IndustrialScientificMedical) frequency range, but the channel that every country is supported or band number different, as shown in Figure 1, the U.S. supports channel1-11, and Japan supports channel1-13.And the ISM band of 5GHz is in the service condition more complicated of every country, as shown in Figure 2, Japan supports channel184,188; The U.S. only supports channel36,40,44,48,149,153,157,161,165, and is illegal or dynamic frequency selection (DFS, DynamicFrequencySelection) channel by other channel definition; China only supports channel149,153,157,161,165, and other channel is forbidden to take.Regulation in the 802.11a/h/j/n consensus standard that content specifically can be formulated with reference to IEEE.
Can know from these descriptions, the channel that country variant is supported is not identical, therefore, when user comes and goes between every country, if be unfamiliar with relevant law and the communication environment of every country, just can not arrange radio communication channel according to local law in real time, communication inconvenience can be caused.
Here, due to third generation partner program (3GPP, The3rdGenerationPartnershipProject) for each country both defines unique Mobile Country Code MCC, based on this, the wireless communication networks of each country possesses unique mobile network's mark.Described mobile network's mark comprises: Mobile Country Code MCC and Mobile Network Code; Wherein, described Mobile Country Code MCC refers to the country belonging to this wireless communication networks, and described Mobile Network Code refers to the network identity of this cordless communication network in belonging country; That is, in each country, the Mobile Country Code MCC of all cordless communication networks is consistent.Therefore, corresponding Wi-Fi national code and WLAN channel corresponding to Wi-Fi national code can be set by Mobile Country Code MCC.
Based on this, in various embodiments of the present invention: the Mobile Country Code MCC of monitoring active wireless network, converts the first corresponding standard national code to by the Mobile Country Code MCC of current network; According to described first standard national code, select corresponding working channel.
