Method and device for adjusting transmission power

Abstract

The embodiment of the invention discloses an emission power adjusting method and device. The method comprises the following steps: a first AP (access point) determining at least one second AP existing in the self first neighbor list; respectively querying whether the first AP exists in a second neighbor list of the at least one second AP saved in a wireless controller AC; determining the second AP corresponding to the second neighbor list in which the first AP exists through the query result as a valid neighbor AP of the first AP; adjusting the self emission power according to the valid neighbor AP. So the number of the neighbor AP required to traversing while adjusting the emission power through the AP can be reduced through the screening the valid neighbor AP for the emission power adjusting for the AP, thereby avoiding the condition of large computation since the AP traverses all neighbor APs on the AC; furthermore, the valid neighbor AP of the first AP is the symmetric neighbor of the first AP, the symmetry of the neighbor AP can be guaranteed through the application of the scheme, and the asymmetric neighbor adjusting problem is avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to a transmission power adjustment method and device. Background technique [0002] With the continuous development of wireless network technology, TPC (Transmit Power Control, transmission power control) technology has been widely used. The traditional RF power control method is to statically set the transmit power of the AP (Access Point, wireless access point) to the maximum value, and simply pursue the signal coverage, but excessive power may cause unnecessary interference to other wireless devices . The application of TPC technology can select an optimal power that can not only take into account the signal coverage of each AP but also meet the usage requirements. [0003] The application of TPC technology can dynamically adjust the transmit power of the AP according to the real-time wireless environment. Specifically, when an AP detects that a neighbor AP i...
