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

摘要

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 systems. ; The present invention is in a broadband mobile access system for providing to integrate non real-time services and real-time service, the broadband mobile packet included in the access system data scheduler according to the methods of adaptive delay threshold based packet scheduling method of allocating radio resources , (a) analyzing whether the terminal analyzes the packet data transmitted to the plurality of user terminals exceeds the delay threshold, receiving the transmitted data packet for requesting the use of the real-time service exists; (B) if there is a terminal for more than the delay threshold receiving the transmitted data packet comprising updating the delay threshold is adaptively; And (c) an adaptive delay threshold based packet scheduling method comprising the step of assigning the radio resource in accordance with the delay threshold updated adaptively in step (b) to the terminal . ; According to the present invention, there is an effect that can while satisfying the service quality requirements required for each service class in a mobile access system that is real-time service and a non-a real-time service is integrated, improve the performance of non-real-time service classes. In other words, when using the preferred embodiment 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, WiMAX (WiBro), resource allocation, packet data scheduling algorithm, real-time services and non-real-time service, QoS, the delay threshold, DTPQ
