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 wifi switching method of a mobile terminal, which is specifically implemented according to the following steps: first, obtain the information of the previous access wifi hotspot of the mobile terminal and the information of the current access wifi hotspot, and send it to the server database; then the server will The wifi hotspot information establishes a wireless access point switching table and calculates the next wifi hotspot with the highest switching probability and other wifi hotspots that may be switched by the user; finally, according to the calculated wifi hotspot switching probability and the monitored real-time data of each wifi hotspot Signal strength, select the best wifi hotspot to switch. A wifi switching method for a mobile terminal, in which not only the information of the current access point but also the information of the previous access point are considered during the switching process, and the next access point is selected according to the historical information. When the moving track of the mobile terminal is relatively fixed, the handover method can effectively shorten the scanning time delay in the handover process when selecting the next access point.

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...
