Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] The embodiment of the present invention provides an interference avoidance method, which is applied to a coordinator, such as figure 1 Shown, including:

[0030] Step 101: When the first terminal device sends an uplink service request message to the first base station, obtain location information of the first terminal device, the first terminal device is within a first coverage area, and the first coverage area is The coverage area ...

Abstract

Embodiments of the present invention provide an interference avoidance method and device, which relate to the communication field, and can effectively avoid interference from terminal equipment to a base station while saving limited spectrum resources. Including: when the first terminal device sends an uplink service request message to the first base station, acquiring the location information of the first terminal device, and the first terminal device is within the first coverage area; judging whether the first terminal device is within the second coverage area , the second base station is adjacent to the first base station, and the second coverage area is smaller than the first coverage area; if the first terminal device is within the second coverage area, determine the base station occupying the least frequency resources among the first base station and the second base station as the The fallback base station sends an interference avoidance message to the fallback base station; receives an interference avoidance response message sent by the fallback base station. The interference avoidance method and device are used for avoiding interference.

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, GSM (Global System of Mobilecommunication, Global System for Mobile Communications) networks and LTE (Long Term Evolution) networks 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 terminal equipment. In remote locations, 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 be d...
