Abstract

This invention is primarily concerned with the method of resource allocation in broadband wireless networks that is executed by a resource allocation server typically located at hub of the network. More specifically, the invention is concerned with the method of distributing transmission bandwidth to requesting wireless access devices using VBDC and FCA mechanisms.

Claims

We claim:
1. A method for resource allocation applicable to a base station unit in broadband terrestrial wireless and satellite networks, comprising the steps of:
(i) performing a first scan of an access device table by calculating the number of data slots for prioritized VBDC grant and for normal VBDC grant to each wireless access device, and calculating the total number of data slots for prioritized VBDC grant and for normal VBDC grant to all wireless access devices in the access device table.

(ii) performing a second scan of the access device table by calculating the total number of data slots available for prioritized VBDC grant, for normal VBDC
grant and for FCA
grant, calculating the number of data slots to be allocated to each access device through prioritized VBDC grant, calculating the total number of credits available to each access device for prioritized VBDC grant, calculating the number of data slots to be allocated to each access device through normal VBDC grant, calculating the total number of data slots to be allocated to each access device, which is the sum of data slots reserved through CRA and RBDC as well as data slots obtained through prioritized and normal VBDC grants, determining if each access device is eligible to receive FCA, calculating the number of data slots to be allocated to each access device through FCA grant, and calculating the total number of credits available to each access device for FCA grant.
