Embodiment 1

[0023] Please refer to figure 1 , figure 1 It is a flow chart of the first preferred embodiment of the method for scanning wireless access points of the present invention. The method for scanning wireless access points includes the following steps:

[0024] Step S101: Obtain the communication frequency band currently occupied by the terminal;

[0025] Step S102: judging whether the communication frequency band is in an interference state; and

[0026] Step S103: If the communication frequency band is in an interference state, stop scanning surrounding wireless access points.

[0027] The following will combine figure 1 The method of scanning for wireless access points is introduced in detail.

[0028] In step S101, when the terminal starts the mode of actively scanning surrounding wireless access points, the terminal will send a detection request frame to wireless access points in the surrounding wireless local area network area on the 2.4GHz frequency band, wherein the d...

Embodiment 2

[0035] Please refer to figure 2 , figure 2 It is a flow chart of the second preferred embodiment of the method for scanning wireless access points of the present invention. The method for scanning wireless access points includes the following steps:

[0036] Step S201: judging whether the terminal currently occupies the communication frequency band for communication;

[0037] Step S202: If the terminal currently occupies a communication frequency band for communication, obtain the communication frequency band currently occupied by the terminal;

[0038] Step S203: judging whether the distance between the communication frequency band and the channel frequency band occupied by the terminal sending the detection request frame is smaller than a preset value;

[0039] Step S204: If yes, stop scanning the surrounding wireless access points; and

[0040] Step S205: If not, continue to scan the surrounding wireless access points.

[0041] The following will combine figure 2 T...

Embodiment 3

[0049] See image 3 , image 3 It is a schematic structural diagram of the first preferred embodiment of the device for scanning wireless access points of the present invention. The device for scanning wireless access points provided in this preferred embodiment includes an acquiring unit 301 , a first judging unit 302 and a scanning stop unit 303 . Wherein, the acquiring unit 301 is configured to acquire the communication frequency band currently occupied by the terminal. The first judging unit 302 is configured to judge whether the communication frequency band is in an interference state according to the communication frequency band. The stop scanning unit 303 is configured to stop scanning surrounding wireless access points when the first judging unit 302 judges that the communication frequency band is in an interference state.

[0050] The following will be combined with image 3 The device for scanning wireless access points will be described in detail.

Abstract

The invention provides a method and a device for scanning wireless access points and a mobile terminal. The method comprises the steps of acquiring the communication band currently occupied by the terminal; judging whether the communication band is in an interference state; and if the communication band is in an interference state, stopping scanning surrounding wireless access points. The method can effectively solve the problem of co-existing interference caused by a reason that a request detection frame sent by the terminal and other communication bands simultaneously work, and also solves the problem of communication quality decline caused by co-existing interference.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, device and mobile terminal for scanning wireless access points. Background technique [0002] A wireless local area network (Wireless Local Area Networks, hereinafter referred to as WLAN) generally uses a 2.4GHz or 5GHz radio frequency band, wherein the frequency coverage of the 2.4GHz frequency band is 2400MHz to 2483.5MHz, and includes 14 sub-channels in total. Frequency bands occupied by Long Term Evolution (hereinafter referred to as LTE) communication technology include Band 7, Band 38, Band 39, Band 40 and Band 41. Among them, the coverage of the Band 7 frequency band is 2500 to 2570MHz, the coverage of the Band 40 frequency band is 2300 to 2400MHz, and the coverage of the Band 41 frequency band is 2496-2690MHz. [0003] It can be seen from the above that the lower frequency part of the 2.4GHz frequency band used by WLAN is similar to the Band 40...
