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 in a packet data radio network. A plurality of mobile stations are assigned to a first uplink channel. A mobile station assigned to the first uplink channel transmits in an uplink transmission block real time information. In response to the transmission, a base station reassigns the other mobile stations that are assigned to the first uplink channel 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 continues transmitting real time information on the first uplink channel.
