SERVICE QOS CONTROL DEVICE THROUGH A BAND REQUEST, CAPABLE OF IMPROVING THE UPLINK PERFORMANCE OF AN ENTIRE SYSTEM, AND A METHOD THEREOF

摘要

PURPOSE: A service QoS control device is provided to control service-based QoS at ranging step by differently processing a band request according to a service access type or a user.;CONSTITUTION: An access probability list is received from a base station(S206). When an uplink traffic to be transmitted to the base station exists, the access permission probability value of a service which is currently used in the probability list is calculated(S208). The result value of a random function and the access permission probability value are compared(S210). When a bandwidth allocation request attempt is determined to an access, a bandwidth allocation ranging is executed to the base station(S212).;COPYRIGHT KIPO 2010
