Method for Adaptive Delay Threshold-based Priority Queueing Scheme for Packet Scheduling in Mobile Broadband Wireless Access System

The present invention relates to an adaptive delay threshold based packet scheduling method for supporting a real-time and non-real-time integration services in a broadband mobile access system. The present invention relates to a real-time service in the broadband mobile access system for providing to integrate the non-real-time service, measures the adaptive delay threshold based packet scheduling method for a packet data scheduler included in the broadband mobile access system assigning radio resources , (a) analyzing whether the number of users by analyzing the packet data sent to the terminal device receives the packet data sent in excess of the delay threshold for requesting the real time services exist; (B) if there is a terminal to receive the transmitted packet data in excess of the delay threshold and updating the delay threshold is adaptively; And (c) according to the delay threshold adaptively updated in said step (b) provides an adaptive delay threshold based packet scheduling method comprising the step of assigning the radio resource to the MS . According to the present invention, there is an effect that can while satisfying the quality of service required for each service class in a mobile access system that provides an integrated real-time services and non-real-time service requirements, improves the performance of non-real-time service classes. In other words, when using the preferred embodiment of A-DTPQ scheduling technique of the present invention, there is an advantage capable of increasing the overall capacity of the mobile access system. Broadband mobile access system, a WiMAX (WiBro), resource allocation, the packet data scheduling algorithm, real-time services and non-real-time service, QoS, the delay threshold, DTPQ
