METHOD OF MULTI-PHASE CALL ADMISSION CONTROL ON WIRELESS INTERNET SYSTEM USING ACTIVE SET

摘要

Provided is a method of multi-phase call admission control on a wireless Internet system using an active set. The method includes the steps of: a) periodically checking, at one base station, active user sets of the base station and neighboring base stations to extract at least one terminal existing simultaneously in the respective active user sets of the predetermined base stations among the checked base stations for a predetermined period of time, and managing the extracted terminal as a stationary active user set; b) checking whether resources for the stationary active user set are available upon exhaustion of resources reserved for new and handover calls; and c) accepting a corresponding call when the resources are available, and rejecting the corresponding call when the resources are not available.
