DYNAMIC CONGESTION CONTROL FOR POWER-BLOCKING SECTORS IN A RADIO TELECOMMUNICATION NETWORK

摘要

A method and congestion controller for controlling congestion in a sector of a cellular telecommunication network that is limited by available downlink transmit power. The network includes a plurality of radio links between a radio base station and User Equipments (UEs) operating in the sector. The controller may first reduce the power of a first subset of the radio links by reducing the packet-switched (PS) downlink target Block Error Rate (BLER) Quality. If the congestion is not resolved within a defined time period, the power of a second subset of the radio links may be reduced by reducing the circuit-switched (CS) DL target BLER Quality. If reducing the PS and CS downlink target BLER Quality does not resolve the congestion, the invention may then implement an existing method of releasing non-guaranteed Air Interface Speech Equivalents (ASEs) and then guaranteed ASEs if required.
