Method for accounting for user terminal connection to a satellite communications system
First Claim
1. A method for operating a satellite communications system, comprising the steps of:
- establishing a wireless connection with a user terminal from a gateway that is coupled to the user terminal through at least one satellite via a forward link and a return link;
during the connection, repetitively determining at the gateway an amount of satellite system resources that are being used to maintain the wireless connection with the user terminal;
after a termination of the wireless connection, outputting system usage data from the gateway, the system usage data indicating at least an amount of satellite system resources that were required to provide the wireless connection with the user terminal;
processing the system usage data from a plurality of gateways to derive a historical record of the satellite system usage;
employing the historical record to predict a future system usage; and
allocating satellite system resources amongst the plurality of gateways in accordance with the predicted future system usage.

Abstract
A method and system for accurately accounting for an amount of satellite communications system resources that are allotted to and utilized by a user terminal on a per call or connection basis. The method accumulates data at periodic intervals during a connection, the data indicating what portion of the overall system resources are utilized on both a forward link (gateway to satellite(s) to user terminal) and on a reverse link (user terminal to satellite(s) to gateway). The usage data can include power levels, data rates, user terminal location, and user terminal type. A Gateway (18) that is assigned to handling the call for the user terminal (13) accumulates the data and subsequently transfers the data over a terrestrial data network (39) to a Ground Operations Control Center (38). The center uses the data to determine an amount to be billed to a service provider associated with a service area that includes the gateway. The center may also uses this data to derive statistical information describing the communications traffic handled by the gateway, and to derive predicted resource allocation and resource scheduling information for the gateway.
