Satellite Hub Based Adaptive Allocation Of Frequency Bands
First Claim
1. In a broadband satellite communication system having a hub and having user terminals within a coverage area and outside a coverage area, the coverage area having at least a portion of spectrum potentially used by a primary user, a method for adaptive allocation of transmission bandwidth, comprising:
- a) determining terminal location of each terminal;
b) reporting terminal location of each terminal to the hub;
c) causing the hub to allocate frequency spectrum for user terminal uplink back to the hub, wherein the spectrum and geographic coverage area of the primary user is excluded from use by first user terminals located within the coverage area; and
d) causing the hub to communicate information on frequency spectrum allocation for each said first user terminal to each said first user terminal and for each said second user terminal to each said second user terminal.

Abstract
A method and system for adaptive allocation of transmission bandwidth in a broadband satellite communication system having user terminals within a coverage area and outside a coverage area, such as an LDMS area. In a specific embodiment, the bandwidth is allocated at a central terminal (hub) to be used by both types of user terminals to communicate back to the hub terminal, wherein the spectrum and geographic coverage area of a primary user is excluded from use by user terminals located within the coverage area.

8. A broadband satellite communication system having a hub and having user terminals within a coverage area and outside a coverage area, the coverage area having at least a portion of spectrum potentially used by a primary user, a subsystem for adaptive allocation of transmission bandwidth, comprising:
-
a) a terminal locator for determining terminal location of each terminal; b) a communicator for reporting terminal location of each terminal to the hub; c) a characteristics allocator for causing the hub to allocate frequency spectrum for user terminal uplink back to the hub, wherein the spectrum and geographic coverage area of the primary user is excluded from use by first user terminals located within the coverage area; and d) a terminal command controller for causing the hub to communicate information on frequency spectrum allocation for each said first user terminal to each said first user terminal and for each said second user terminal to each said second user terminal. - View Dependent Claims (9, 10, 11, 12, 13, 14)
