Base station, cognitive radio system, and control method for a neighbour relationship

摘要

Provided is a cognitive radio system CRS, a base station and a method for controlling a neighbor relationship, including: a serving base station actively notifies a neighbor base station of transport layer configuration information after resource reconfiguration, the neighbor base station thus performs a maintenance operation on locally saved neighbor cell information of the serving base station, which can solve the problem that the change in the neighbor relationship affects terminal services.

1. A method for resource configuration and maintenance operation neighboring base station(s) in a cognitive radio system (CRS), comprising:
when resource reconfiguration occurs in a serving base station, actively notifying, by the serving base station, a neighbouring base station of transport layer configuration information after the resource reconfiguration; receiving, by the neighbouring base station of a serving base station, the transport layer configuration information of which the serving base station actively notifies the neighbouring base station after resource reconfiguration, and performing a maintenance operation on locally saved neighbour cell information of the serving base station; sending, by the neighbouring base station, the transport layer configuration information to a subordinate terminal after receiving the transport layer configuration information, wherein the transport layer configuration information includes a new frequency point of the serving base station; measuring, by the subordinate terminal, the new frequency point of the serving base station and reselecting or switching to the new frequency point of the serving base station when signal intensity of the new frequency point of the serving base station is greater than a certain value.
