System and method for managing congestion in a satellite communications network
First Claim
1. A system for managing data congestion in a communications network which establishes communication cells at respective locations on the surface of the earth to enable communication between a plurality of user terminals and at least one network controller, comprising:
- a congestion determiner, adapted to determine that data congestion exists in said network which interferes with an ability of at least one user terminal to communicate in said network; and
a congestion controller, adapted to control at least one of downlinking of data from said network controller to at least one select group of said user terminals and uplinking of data from said at least one select group of said user terminals to said network controller, in response to said determined data congestion.

Abstract
A system and method for controlling data congestion affecting user terminals in a communications network, such as satellite terminals in a satellite communications network. The system and method employs a congestion detector adapted to determine that data congestion exists in the network which interferes with an ability of at least one user terminal to communicate in the network, and a congestion controller, adapted to control downlinking of data from the network controller to at least one select group of the user terminals and uplinking of data from at least one select group of the user terminals to the network controller, in response to the data congestion. The congestion controller and control downlinking and uplinking of data to and from the select group or groups of terminals based on criteria such as user terminals which are all located within a single uplink cell or user terminals which are located within all uplink cells in said network.

6. A method for managing congestion in a communications network which establishes communication cells at respective locations on the surface of the earth to enable communication between a plurality of user terminals and at least one network controller, comprising:
-
determining the existence of data congestion in said network which interferes with an ability of at least one user terminal to communicate in said network; and
controlling at least one of downlinking of data from said network controller to at least one select group of said user terminals and uplinking of data from at least one select group of said user terminals to said network controller, in response to said data congestion. - View Dependent Claims (7, 8, 9, 10)

11. A computer-readable medium of instructions, adapted to control a communications network to manage congestion in a communications network which establishes communication cells at respective locations on the surface of the earth to enable communication between a plurality of user terminals and at least one network controller, comprising:
-
a first set of instruction, adapted to control the communications network to determine that data congestion exists in said network which interferes with an ability of at least one user terminal to communicate in said network; and
a second set of instruction, adapted to control at least one of downlinking of data from said network controller to at least one select group of said user terminals and uplinking of data from at least one select group of said user terminals to said network controller, in response to said determined data congestion. - View Dependent Claims (12, 13, 14, 15)
