Abstract

An embodiment of the invention provides an interference avoidance method and device, relates to the field of communications, and aims to effectively avoid terminal devices interfering a base station and save limited spectrum resources. The method includes: when a first terminal device transmits an uplink service request message to a first base station, location of the first terminal device is acquired, and the first terminal device is in a first coverage area; whether the first terminal device is in a second coverage area or not is judged, a second base station is close to the first base station, and the second coverage area is smaller than the first coverage area; if the first terminal device is in the second coverage area, one using smallest frequency resources is selected from the first base station and the second base station as a return base station, and an interference avoidance message is sent to the return base station; an interference avoidance response message transmitted by the return base station is received. The interference avoidance method and device is applicable to interference avoidance.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to an interference avoidance method and equipment. Background technique [0002] With the development of communication technology, a scene where networks of different mobile communication standards coexist appears in the communication system. Different networks have different characteristics, and corresponding terminal devices in different networks also have different characteristics. For example, a GSM (Global System of Mobile Communication, Global System of Mobile Communication) network and an LTE (Long Term Evolution) network use adjacent spectrum resources to cover the same area. The macro base stations of the GSM network are deployed in high-rise buildings and equidistant GSM terminals. The device is located far away, usually the distance between the GSM terminal equipment and the macro base station is more than 30 meters, and the small cell base station of the LTE network may ...
