METHOD AND SYSTEM FOR FAST ACCESS TO AN UPLINK CHANNEL IN A MOBILE COMMUNICATIONS NETWORK

摘要

A method and system are disclosed for fast access to an uplink channel for a mobile station (10) in a packet data radio network (6). A plurality of mobile stations (10) are assigned to a first uplink channel. A mobile station (10) assigned to the first uplink channel (UL1) transmits in an uplink transmission block real time information. In response to the transmission, a base station (26) reassigns the other mobile stations (10) that are assigned to the first uplink channel (UL1) and are involved in the communication of real time information in a downlink transmission block immediately following the uplink transmission block. Thereafter, the first mobile station (10) continues transmitting real time information on the first uplink channel (UL1).
