ADMISSION CONTROL AND RESOURCE ALLOCATION IN COMMUNICATION SYSTEM FOR SUPPORTING QUALITY OF SERVICE

摘要

PROBLEM TO BE SOLVED: To provide admission control and resource allocation in a communication system for supporting application flows having quality-of-service requirements.SOLUTION: An Access Network (AN) element determines available resources. When available resources are sufficient to support the requirements of a requested application flow, the AN admits the application flow. The AN periodically, and on trigger events, updates metric of available resources. The admission control may operate in coordination with a scheduler applying a compensation factor to each flow type, and a compensation factor for aggregate flows of a given user.
