Transmitting power control method for wireless local area network and mobile terminal

Abstract

The embodiment of the invention discloses a transmitting power control method for a wireless local area network and a mobile terminal. The method comprises the steps of detecting whether a state parameter of at least one wireless network satisfies a preset condition or not, wherein the state parameter is obtained by scanning by the mobile terminal, and the at least one wireless network corresponds to at least one available wireless access point; adjusting transmitting power of transmitting data to the at least one available wireless access point when it is detected that the state parameter of the at least one wireless network satisfies the preset condition; and transmitting the data to a target wireless access point according to the transmitting power after adjustment when the wireless network corresponding to the target wireless access point is accessed and a data transmitting request for an application is detected, wherein the transmitting power after adjustment is lower than the transmitting power before adjustment. The embodiment of the invention also discloses the corresponding mobile terminal. According to the method and the mobile terminal, the mutual interference between the mobile terminals can be reduced, and the communication quality is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a transmission power control method of a wireless local area network and a mobile terminal. Background technique [0002] With the increasing development of wireless network technologies, a WLAN (Wireless Local Area Network, wireless local area network) capable of providing a local area network wireless connection service is more and more widely used. The wireless access point AP is a wireless transceiver device in the WLAN, which converts the data received from the wired network into wireless signals for transmission, and converts the received wireless signals into data and forwards them to the wired network. [0003] At present, WLANs based on the IEEE 802.11 specification have been widely used. However, due to the lack of professional WLAN network deployment knowledge in use by users, there are too many APs per unit area, that is, high-density AP distribution. Due to...

Problems solved by technology

However, due to the lack of professional WLAN network deployment knowledge in use, there are too many APs per unit area, that is, high-density AP distribution. Due to the existence of the Clear Channel Assessment (CCA) mechanism in the protocol, mobile terminals The WLAN chip needs to evaluate whether the channel is idle before transmitting a signal to the air interface

If it is idle, the message can be sent after the conflict avoidance algorithm is executed; if it is busy, it needs to wait, so it will cause serious interference between mobile terminals and mobile terminals, resulting in a decline in communication quality
