Wireless intelligent roaming method, system and device

Abstract

The invention relates to a wireless intelligent roaming method, system and device. The wireless intelligent roaming method comprises the following steps: when a first external wireless accessing point detects that the intensity of an accessed terminal signal is lower than a pre-set roaming signal threshold value, reporting a weak signal event to a main wireless accessing point through UPnP (Universal Plug-n-Play), wherein the event carries an MAC (Media Access Control) address of a terminal network card; transmitting a terminal scanning request to at least one second external wireless accessing point by the main wireless accessing point through the UPnP, wherein the request carries the MAC address; scanning a corresponding terminal of the MAC address by the second external wireless accessing point; after finding the terminal, reporting a scanning result to the main wireless accessing point through the UPnP so that the main wireless accessing point can select a target external wireless accessing point with the highest priority; receiving a correlation relieving request transmitted by the main wireless accessing point through the first external wireless accessing point, and transmitting a relieving frame to the terminal so as to relieve correlation, wherein a terminal correlation request is not responded during a first pre-set duration; and establishing connection between the target external wireless accessing point and the terminal by responding the terminal correlation request through the target external wireless accessing point, so as to improve network performances.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a wireless intelligent roaming method, system and device. Background technique [0002] With the development of wireless network technology, more and more homes or offices use wireless routers for wireless communication, but the signal coverage of the wireless router is limited. Once the coverage is exceeded, the wireless signal is weak. In order to expand the range of wireless signals, multiple wireless access points (AccessPoint, hereinafter referred to as AP) are usually set up to derive wireless network signals for wireless terminals (Station, hereinafter referred to as STA) to access to realize the Internet function. [0003] In the traditional method, a STA1 connects to an AP1 at the beginning, and then the STA moves. As the distance from AP1 increases, the signal becomes weaker, which cannot meet the Internet access requirements of STA1. However, STA1 will not acti...

Problems solved by technology

[0003] In the traditional method, a STA1 is connected to an AP1 at the beginning, and then the STA moves. As the distance between the STA and the AP1 increases, the signal becomes weaker and cannot meet the Internet access requirements of the STA1. However, at this time, the STA1 will not actively disconnect. Open the connection with AP1 for automatic roaming

At the same time, when STA1 is connected to AP1 with a weak signal, a large number of wireless frames will be retransmitted, thus affecting the performance of the entire network
