Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] A kind of wifi switching method of mobile terminal of the present invention, as figure 1 As shown, the specific steps are as follows:

[0027] Step 1: Initialize and connect to the first wifi hotspot;

[0028] Step 2: Obtain the information of the previous access to the wifi hotspot of the mobile terminal and the information of the current access to the wifi hotspot. The information of the wifi hotspot includes the name of the wifi hotspot, the signal strength and the number of hotspots;

[0029] Step 3: Send the wifi hotspot information obtained in step 2 to the server database through the wireless transmission module;

[0030] Step 4: The server uses the information in step 3 to create a switching table for the wireless access point;

[0031] Step 5: The server calculates the wifi hotspot with the greatest next switching probabili...

Abstract

The invention discloses a mobile terminal wifi switching method. The method comprises the steps that the information of an access wifi hotspot before a mobile terminal and the information of a current access wifi hotspot are acquired and sent to a server database; the server establishes a wireless access point switching table according to the wifi hotspot information, and calculates user's next wifi hotspot with the largest switching probability and other possible switching wifi hotspots; and finally, according to the calculated wifi hotspot switching probability and monitored real-time signal strength of each wifi hotspot, an optimal wifi hotspot is selected for switching. According to the mobile terminal wifi switching method, in a switching process, the information of the current access point and the information of a previous access point are considered; based on historical information, a next access point is selected; and if the moving trajectory of the mobile terminal is fixed, the scan time delay of the switching process can be effectively shortened when a next access point is selected according to the switching method.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and relates to a wifi switching method of a mobile terminal. Background technique [0002] wifi (Wireless Fidelity) technology is a wireless local area network based on 802.11 series standards. In a barrier-free open environment, the communication distance of the wifi network can generally reach 305m; in a closed and limited space, the communication distance is generally about 76-122m, which satisfies people's use of mobile devices to access the Internet to query information at any time and entertainment needs, and better get rid of the limitations of traditional physical equipment, bringing more convenience to people's lives. [0003] WLAN based on IEEE 802.11 protocol can provide sufficient bandwidth for wireless multimedia applications, but the limited coverage of wireless APs (Access Points) will cause mobile terminals to switch between different APs frequently. So handover man...
