Problems solved by technology

After that, when there is a terminal that needs to be accessed in the common coverage area of ​​the two base stations, it will be unable to access the network due to mutual interference between the two BS0 and BS2, forming a coverage blind area and reducing the communication performance of the wireless network

Embodiment Construction

[0055] The present invention specifically proposes a potential channel interference detection using the silent period of the base station system (that is, the period when the base station does not transmit and receive information), thereby reducing blind areas in the communication system and effectively improving the access success rate of terminals in the blind areas.

[0056] The specific implementation solutions provided by the present invention will be described below.

[0057] The present invention mainly comprises three processing procedures in concrete realization process, specifically comprises:

[0058] (1) The first treatment process

[0059] During this process, it is necessary to detect the status of each channel of the base station, so that the base station can know the status of each channel at each moment, so as to determine whether the corresponding channel can be occupied or unoccupied according to the status;

[0060] This process is specifically implemented...

Abstract

The invention relates to a terminal access method, device and system in a wireless communication system. In the invention, a base station of the wireless communication system carries out a transceiving operation by using a primary channel and a secondary channel, and a periodicity of the base station is switched between the primary channel and the secondary channel. The method also includes the following steps: after the terminal to be accessed determines that the access operation is not completed through the primary channel of the base station, an interference state of the primary channel ofthe base station is detected. The detecting result of the interference state is transmitted to the base station by the secondary channel of the base station, and the interference state is eliminated by the base station according to the testing result of the interference state. After an operation of interference elimination, the base station notices the terminal to implement the access operation through the primary channel again. Therefore, the invention is able to improve a success rate of the terminal access in the base station system, and on the other hand, the invention is able to reduce dead zones of the communication system and thereby to improve communication performance of the wireless network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a solution for realizing channel interference detection. Background technique [0002] In a wireless communication system, the wireless spectrum is divided into a licensed frequency band and an unlicensed frequency band. Among them, the authorized frequency band is a wireless transmission frequency band specially developed for a certain wireless communication service, and other wireless devices cannot perform signal transmission in this frequency band; The frequency bands used by each node are optimized to reduce mutual interference between nodes. The unlicensed frequency band can be used freely for all wireless communication services that meet certain requirements. However, since the frequency points used by each node are not fixed, and the network is not optimized based on this frequency band, in order to avoid the unlicensed frequency band. Interference affect...
