METHODS AND RADIO BASE STATIONS FOR DETERMINING PERFORMANCE STATE OF A CELL

摘要

The invention relates to a method in a first radio base station (10) for determining a performance state of a first cell (12) served by the first radio base station (10), which first radio base station (10) is comprised in a radio communications network. The method comprises determining (201,301,401 ) traffic statistics of the first cell (12), comparing (202,302,402) the traffic statistics with a threshold value, when the determined traffic statistics goes beyond the threshold value, transmitting (204,303,403) a data request to a second radio base station (14) requesting data retrieved in or associated with a second cell (16) to be used to determine performance state of the first cell (12), receiving (208,306,404) a data response indicating the requested data from the second radio base station (14), and determining (209,307,405) the performance state of the first cell (12) based on the data response.
