Wireless communication method and wireless communication device

Abstract

The invention provides a wireless communication method. The wireless communication method includes the steps that an internet protocol address configuration request frame is generated and at least comprises internet protocol address repeated use identification, and the internet protocol address repeated use identification is used for instructing a target communication device receiving an internet protocol address configuration message frame; after switching from a current communication device to the target communication device, the sender of the internet protocol address configuration request frame still uses the current IP configuration parameters; the internet protocol address configuration request frame is sent, and a returned internet protocol address configuration response frame is received. The invention further provides the corresponding wireless communication device. Due to the technical scheme, after switching from a current access point / base station to a target access point, a terminal still uses the current IP configuration parameters, so that the step of applying the IP configuration parameters again is saved, the process of executing access point switching is favorable for being saved for the terminal, the switching time is shortened, and the fast switching operation of the terminal is achieved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular, to a wireless communication method and a wireless communication device. Background technique [0002] In the current WLAN technology, when a STA (terminal) switches from one AP / BS (Access Point, Base station base station) to another AP, there are two methods for re-establishing the connection. [0003] The first method is as figure 1 As shown, it is called FT over the air (air fast switching; among them, FT is Fast Transition, fast switching), and its specific execution steps include: [0004] The terminal establishes a connection with the current access point / base station. The terminal can perform operations such as data transmission with the current access point / base station. [0005] The terminal sends an authentication request frame to the target access point. [0006] The target access point returns an authentication response frame to the terminal. ...

AI Technical Summary

Problems solved by technology

[0024] 1: The STA has already allocated IP configuration parameters, and re-applies for IP configuration parameters after switching, which shortens the effective communication time, and the process of re-applying for IP configuration parameters may not achieve the purpose of fast switching;

[0025] 2: For the current AP / base station, there is a process of requesting resource release from the DHCP server, which is not conducive to the power saving of the current AP / base station and the DHCP server, and at the same time increases unnecessary signaling
