Abstract:
1. A method for setting an uplink transmission rate limit for a mobile terminal operating in a mobile communications network supporting mobile radio communication using radio channels associated with a cell coverage area including a high speed downlink shared radio channel for transmitting information from the mobile communications network to mobile terminals and uplink channels for transmitting information from the mobile terminals to the mobile communications network, where a first one of the mobile terminals receives information from the mobile communications network over the high speed-downlink shared channel and transmits information to the mobile communications network over a first uplink channel, said method implemented by at least one of a base station and a radio network controller comprising the steps of: determining a first downlink channel quality associated with a first transmission of information over the high speed downlink shared radio channel to the first mobile terminal; determining a first uplink transmission rate limit for information to be transmitted over the first uplink channel by the first mobile terminal based on the first downlink channel quality; wherein the determined first uplink transmission rate limit is a function of the first downlink channel quality, a load associated with the first uplink channel, and a number of mobile terminals transmitting in uplink direction to the mobile communications network; and wherein the at least one of the base station and the radio network controller implements the first and second determining steps to determine the first uplink transmission rate limit for the first mobile terminal by monitoring the first downlink channel quality and scaling the first downlink channel quality to a reference value, wherein the reference value is determined by an uplink load, a number of mobile terminals in the cell coverage area, a subscription associated with the first mobile terminal, and a priority level associated with a mobile connection to the first mobile terminal.
