METHOD FOR CONTROLLING REVERSE LINK IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A method for controlling a reverse link in a mobile communication system is provided to assign variations of reverse data transfer rates differently according to characteristics of each mobile terminal, and to control access possibility according access possibilities allocated from a base station when a mobile terminal changes a data transfer rate. CONSTITUTION: A mobile terminal transmits a request message for connection open to a base station, and the base station acquires the mobile terminal(100). The base station sends a configuration message with a PV(Persistence Vector) value during configuration negotiation to the mobile terminal(102). If connection setup is completed(104), the base station transceives packet data with the mobile terminal. Each mobile terminal transmits an RRI(Reverse Rate Indicator) symbol to the base station to notify self reverse data transfer rate, and the base station monitors an RRI message(106), to set an RAB(Reverse Activity Bit) based on remaining capacity and a reverse link load(108). The base station broadcasts the set RAB bit to a cell through an F-MAC(Forward link Medium Access Control) channel(110). And after a predetermined time, the base station returns to the step 106.
