PACKET SCHEDULING SYSTEM AND METHOD IN MOBILE COMMUNICATION SYSTEM

摘要

Disclosed is a scheduling system and method in a mobile communication system. In the algorithm applied to the scheduling system and method, a packet loss probability on an input real-time traffic packet is calculated, different weights are assigned depending on the condition whether the calculated packet loss probability exceeds the maximum packet loss requirement probability, and a priority metric is determined. In this instance, the weights are established to be higher as the calculated packet loss probability approaches the maximum packet loss. The packet scheduling process is performed according to the determined priority metric. The above-noted scheduling algorithm guarantees the maximum packet loss rate in the real-time traffic, and increases system capacity.
