Abstract
A method and system for controlling congestion on a packet switched radio channel (PRCH) is disclosed. A PRCH congestion control function determines if the average time delay for packet calls on the PRCH is within a delay alarm level. If the average time delay is not within the delay alarm level, it is then determined which packet calls to expel from the PRCH in order to decrease the average time delay. The determination of congestion may be made for each of the uplink and downlink of a PRCH separately, or, on the combined uplink and downlink of the PRCH.
