The present invention relates to a method for congestion control when setting up calls in a cellular CDMA-based communication system. A call setup request from a user equipment in a congested cell is prohibited by means of broadcasted call admission messages. However, the call admission information indicates permitted and/or restricted accesses for carrier frequencies and/or neighbored cells. Neighbored cells using the same carrier frequency as the congested cell are marked with a restricted access flag. Therefore, the user equipments in the congested cell will request for a call setup only in one of those neighbor cells without access restrictions. By this means, the user equipments will not contribute to the interference level in the congested cell. |
