Problems solved by technology

For example, design errors may be costly or complicated to correct, as would be the case if each user terminal 100 required service
also, operational adjustments to satellite communication systems can be difficult for similar reasons
For example, changes in the characteristics of inclined orbits are difficult to accommodate without changing the individual user terminals

Abstract

Methods of registering a user terminal at a satellite communications system including a plurality of satellite spot beam transceivers, wherein each of the satellite spot beam transceivers defines a respective spot beam. The current spot beam registration information is transmitted from the user terminal to the satellite communications system. Updated spot beam registration information is determined for the user terminal at the satellite communications system based on the current spot beam registration information received from the user terminal. Updated spot beam registration information is transmitted from the satellite communications system to the user terminal. The user terminal updates the current spot beam registration information for the user terminal using the updated spot beam registration information received from the satellite communications system. Related systems and user terminals are also discussed.

Description

field of invention [0001] The present invention relates to the field of communications, and more particularly to systems and methods for satellite communications. Background of the invention [0002] When users move within a geographical range, the mobile communication system enables users to access the communication network through their respective user terminals. Some mobile communication systems divide the geographical area into regions, each region can be covered by a part of the mobile communication system. Therefore, if a user moves from a first zone to a second zone within the geographical area being served, the mobile communication system may stop providing service in the first zone and start providing service in the second zone to maintain the user's access. A user can use a user terminal to access the mobile communication system. [0003] FIG. 1A shows a satellite communication system providing communication services to user terminals locate...
