Wireless communication method and wireless communication device

Abstract

The present invention provides a wireless communication method, comprising: generating an Internet protocol address configuration request frame, which at least includes an Internet protocol address reuse identifier, and the Internet protocol address reuse identifier is used to send a target communication device that receives an Internet protocol address configuration message frame Instruction: the sender of the IP address configuration request frame still uses the current IP configuration parameters after switching from the current communication device to the target communication device; sends the IP address configuration request frame, and receives the returned IP address configuration response frame. The invention also proposes corresponding wireless communication equipment. Through the technical solution of the present invention, after the terminal is switched from the current access point / base station to the target access point, the current IP configuration parameters are still used, thereby eliminating the need to re-apply for the IP configuration parameters, which is beneficial to save the terminal from performing access The step-by-step process of point switching shortens the switching time, thereby realizing the fast switching operation of the terminal.

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, Basestation 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 (fast switching in the air; among them, FT is FastTransition, 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
