Management of spotbeam selection information in satellite mobile communication systems
First Claim
1. A user terminal operable to acquire service in a satellite mobile communication network in which plural service providers each communicate via satellite with users on one or more spotbeams each having a select frequency, the user terminal comprising:
- a communication system including a transmitter and a receiver for communicating via a spotbeam;
a memory for storing frequency information, the frequency information identifying carrier frequencies associated with the spotbeams in the network, the memory further storing identification information identifying a service provider associated with each carrier frequency; and
a communication controller operatively associated with the communication system and the memory for selecting a spotbeam carrier frequency to communicate on, the communication controller utilizing the identification information to select the spotbeam carrier frequency.

Abstract
A user terminal is operable to acquire service in a satellite mobile communication network in which plural service providers each communicate via satellite with users on one or more spotbeams each having a select frequency. The user terminal comprises a communication system including a transmitter and a receiver for communicating via a spotbeam. A memory stores frequency information. The frequency information identifies carrier frequencies associated with the spotbeams in the network. The memory further stores identification information identifying a service provider associated with each carrier frequency. A communication controller is operatively associated with the communication system and the memory for selecting a spotbeam carrier frequency to communicate on, the communication controller utilizing identification information to select the spotbeam carrier frequency.
