WCDMA MOBILE COMMUNICATION SYSTEM

摘要

A WCDMA mobile communication system that makes it possible for a mobile device to use the minimum radio resources more directly (that is, at the level of an earlier stage) by controlling the states of the uplink and downlink separately, wherein the mobile station includes monitoring unit for monitoring the uplink data flow amount; state determination unit for determining a desired uplink state from the monitoring result of the data flow amount of the monitoring unit; and transmission unit for transmitting a request to establish the uplink state determined by the state determination unit to the base transceiver station apparatus; and the base transceiver station apparatus comprises determination unit for determining an uplink state in response to the uplink state change request; and unit for communicating a change in the determined uplink state by way of response to the mobile station.
