A PACKET SCHEDULING METHOD FOR WIRELESS COMMUNICATION SYSTEM

摘要

The present invention provides a packet scheduling method for wireless communication system, the user packet queues to be transmitted are divided into the user packet queues having packet losing and the user packet queues having no packet losing; For the user packet queues having packet losing, a user connection will be terminated if a real time packet losing rates of a user exceed a threshold for predetermined packet losing rates; And scheduling user packets according to the sizes of packet losing rates if a real time packet losing rates of a user do not exceed the threshold for predetermined packet losing rates; For the user packet queues having no packet losing , making a scheduling according to the length of packet , the channel conditions,delay,delay variation. In the case of existing packet losing within certain range, the packet losing rates will be decreased by means of scheduling the users who have higher packet losing rates firstly; And the user's communication quality will be increased by considering the requirements of packet services which are sensitive to the users of delay variation, and by restricting constant delay variation.
