Flow-based call admission control for wireless communication systems
First Claim
Patent Images
1. A method of communicating, comprising:
- using a base station for serving at least one sector;
determining whether to admit a new call to the sector based on a flow of the new call;
determining that the flow of the new call is a low priority flow;
admitting the new call; and
setting a merge threshold of the low priority flow of the new call and any existing low priority flows to a high value, the high value ensuring that the low priority flow will not interfere with an ability to meet quality of service requirements for higher priority flows.

Abstract
A wireless communication system (20) includes a call admission module (40) that determines whether to admit a new call based upon a flow of the new call. In a disclosed example, the call admission module (40) predicts a loading of a sector resulting from admission of the new flow. Provided that the new flow will fit within a sector capacity or there are sufficient resources that can be reallocated within the sector to accommodate the new flow and satisfy quality of service requirements for the new flow and existing flows, the new call will be admitted.

using a base station for serving at least one sector;
determining whether to admit a new call based on a flow of the new call; and
determining that the flow of the new call is a low priority flow;
admitting the new call; and
setting a merge threshold for at least one low priority flow and any existing lows priority flow to a high value that ensures that the low priority flow will not interfere with an ability to satisfy a quality of service requirement of at least one other higher priority flow.- View Dependent Claims (15)
