Method and system for collecting and reporting interference source information

A terminal device, comprising a broadcast message receiving unit, a broadcast message processing unit and an interference report message sending unit;

• the broadcast message receiving unit, configured to receive a broadcast message carrying Neighbor BS (NBS) identification information that is sent by an NBS of an operating base station (OBS);
• the broadcast message processing unit, configured to generate an interference report message carrying the broadcast message and receiving time information in response to receiving the broadcast message correctly and send the interference report message to the OBS via the interference report message sending unit, and to generate an interference report message carrying receiving time information in response to receiving the broadcast message incorrectly and send the interference report message to the OBS via the interference report message sending unit.

A base station (BS), comprising an interference report message receiving unit and an interference report message processing unit;

• the interference report message receiving unit, configured to receive interference report messages sent by each terminal;
• the interference report message processing unit, configured to record, as an interference source identification of a terminal, Neighbor BS (NBS) identification information carried in a broadcast message reported by the terminal that receives the broadcast message sent by an NBS correctly, and to determine, from the recorded interference sources, an interference source identification of a terminal that does not report the broadcast message, according to association relationship of receiving time information of the broadcast message, where the receiving time information is reported by each terminal.

A method of operating a base station (BS) comprising:

• receiving interference report messages sent by each terminal;
• recording, as an interference source identification of a terminal, Neighbor BS (NBS) identification information carried in a broadcast message reported by the terminal that receives the broadcast message sent by an NBS correctly, and to determine, from the recorded interference sources, an interference source identification of a terminal that does not report the broadcast message, according to association relationship of receiving time information of the broadcast message, where the receiving time information is reported by each terminal.
