Embodiment Construction

[0024] Refer below Figure 1 to Figure 3 Principles and exemplary embodiments of the present invention are described.

[0025] The method of the present invention is under a WIFI wireless local area network environment with multiple APs, a smart device (the smart device is represented by an Android smart phone below, but the present invention is not limited thereto) and a communication server for active communication when a disconnection switch occurs How to reconnect after network disconnection.

[0026] The communication method between the Android smart phone and the communication server is as follows: figure 1 shown. The Android smart phone first needs to establish a communication link with an AP in the WIFI wireless local area network environment, and then connect to the backbone WIFI network / Internet network through the switch, and then communicate with the communication server through the switch. The backbone WIFI network / Internet network is a public wireless network,...

Abstract

The invention relates to a WIFI disconnected network reconnection method of an intelligent device in a WIFI wireless local network environment. The WIFI disconnected network reconnection method is characterized in that WIFI scanning can be carried out to acquire a WIFI scanning result list; the elements of the WIFI scanning result list can be ordered according to the signal intensity values; the AP having the maximum signal intensity values of the intelligent device and the ordering result list can be connected together. The ordering steps are as follows: (1) the AP having the maximum signal intensity value can be selected from the WIFI scanning result list by adopting the bubble sort method; (2) the found AP having the maximum signal intensity value can be removed from the WIFI scanning result list; (3) the AP having the maximum signal intensity value can be added to the new result list;(4) the step (1), the step (21), and the step (3) can be repeated till the WIFI scanning result list is empty. The frequent switching problem caused by the uncertainty of the connected AP during the disconnected network switching process can be solved, and the connection with the AP having the strongest signal intensity can be guaranteed every time when the network is switched, and therefore the switching frequency can be reduced, and the communication stability can be improved.

Description

technical field [0001] The invention relates to a WIFI network connection method of an intelligent device, in particular to a WIFI disconnection and reconnection method of an intelligent device under a WIFI wireless local area network environment. Background technique [0002] When smart devices such as Android smartphones and tablets are connected to the network through wireless hotspot APs, due to the limitation of a single AP covering a limited area, multiple APs are usually used for coverage in a larger area. At the same time, the problem is that the smart device will roam and switch off the network during the mobile communication process. The uncertainty of the connected AP during the disconnection switching process will cause frequent switching problems. Contents of the invention [0003] The present invention relates to the software communication design of smart devices such as Android smartphones and tablet phones and the network communication through AP (AP, Acce...
