Abstract

The invention discloses a heterogeneous wireless network rapid roaming method, a heterogeneous wireless network rapid roaming system, a master access point device and a slave access point device. Therapid roaming method for the heterogeneous wireless network comprises the following steps: performing collaborative networking on slave access point equipment and master access point equipment; rapidroaming related information of the wireless terminal is transmitted between the slave access point device and the master access point device, so that rapid roaming of the wireless terminal between different access point devices is realized. According to the invention, rapid roaming and switching of the wireless terminal when the wireless terminal moves among a plurality of access point devices canbe realized. The roaming process can be shortened, and the switching time is shortened.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a heterogeneous wireless network fast roaming method and system, and master and slave access point devices. Background technique [0002] There are generally multiple devices providing wireless access such as home gateways and wireless routers produced by different manufacturers in the user's home, and in most cases the wireless coverage of these devices will overlap with each other to a certain extent. Contents of the invention [0003] The applicant found that: when the user moves in the home, STA (Station, workstation, wireless terminal) such as mobile phone, PAD (portable android device, tablet computer) sometimes cannot automatically and quickly switch to the AP (Access Point, Access point) equipment, or the switching time is too long (more than ten seconds), it cannot guarantee that the existing business will not be interrupted, especially for VoWiFi (Voice over WiFi, voi...
