Abstract

See full text

A mobile station detects whether there is congestion in a cell by monitoring a first channel fix downlink messages and decoding the messages to see if the decoded messages indicate congestion, where the first channel is a common control channel (CCCH). For the case in which the mobile station determines from the decoded messages that there is no congestion, the mobile station initiates a random access procedure by transmitting a request message uplink on a random access channel (RACH). Else for the case in which the mobile station determines from the decoded messages that there is congestion, the mobile station waits for a waiting time before initiating a random access procedure.
