METHOD FOR SCHEDULING HETEROGENEOUS TRAFFIC IN B3G/4G CELLULAR NETWORK WITH MULTIPLE CHANNELS

摘要

PPROBLEM TO BE SOLVED: To provide a method and apparatus for scheduling heterogeneous traffic in B3G/4G cellular networks. PSOLUTION: A method includes tracking average user throughput or the like for every user that is serviced; determining a potential schedule set responsive to user requirements responsive to minimum rate guarantee for data flows and maximum tolerable delay and jitter guarantees for voice flows; with multiple flows for each user, first determining contending flow for each user responsive to aggregate rate feedback; obtaining search space for the user requirements of rate, delay and jitter responsive to corresponding optimizing strategies; determining individual rate, delay and jitter related schedules providing maximum incremental or marginal utility; and calculating final schedule of users on channels providing maximum incremental or marginal utility among parameter specific schedules from the determining step.
