A method for network switching using bluetooth hotspot

Abstract

The invention discloses a method for network switching by using a Bluetooth hotspot, comprising: at least three Bluetooth base stations respectively sending broadcast messages according to a preset time period; Calculate the power attenuation value and the function of the power attenuation value with the distance, calculate the distance between the mobile terminal and each Bluetooth base station, and finally calculate and store the current location information of the mobile terminal; the background server according to the current location of the mobile terminal The position information before the information is used to obtain the movement track of the mobile terminal, and predict the candidate WIFI access point to which the next position of the mobile terminal will arrive according to the movement track; the Bluetooth connection between the mobile terminal and the candidate WIFI access point or the candidate WIFI access point The hotspot completes the pre-connection; when the location information of the mobile terminal received by the background server belongs to the switching area, the switching operation is completed.

Description

technical field [0001] The invention relates to the field of wireless networks, in particular to a method for network switching by using a bluetooth hotspot. Background technique [0002] With the popularization of wireless network communication, more and more homes, offices and public service places have achieved WIFI coverage. In actual usage scenarios, since the signal coverage of each wireless router is limited, for larger places, multiple wireless routers need to be networked to provide signal coverage. Therefore, the mobile device may involve switching connections between multiple routers during the movement process. [0003] In the current technology, the hotspot switching method of the mobile device in the public area covered by multiple wireless hotspots is generally as follows: when the mobile device recognizes that the strength of the wireless signal is lower than a certain threshold, it will disconnect from the hotspot. Look for other wireless access point APs ...

AI Technical Summary

Problems solved by technology

When the user moves to an area where the signals of two APs overlap, a situation may arise: after connecting to AP1, the user will always be connected to AP1, and after arriving near AP2, even if the signal of AP2 is stronger than the signal of AP1, as long as If the switching threshold is not reached, the mobile device will still be connected to AP1 and will not switch to AP2

Moreover, due to the need to re-handshake and negotiate after disconnecting the old connection and before establishing a connection with the new AP, it often happens that when the device moves to the edge coverage area of ​​the wireless access point, it will be temporarily disconnected and the signal will be completed. After the switch, you can reconnect to the Internet, and the switch time is slow, resulting in poor user experience
