Handoff for satellite communication
First Claim
1. A method of communication, comprising:
- generating satellite handoff information that specifies a handoff time for a particular cell of a particular satellite;
receiving a measurement message from a user terminal;
modifying the satellite handoff information based on the measurement message; and
sending the modified satellite handoff information to the user terminal.

Abstract
Various aspects of the disclosure relate to handoff of a user terminal in communication with a satellite network portal through a satellite. In some aspects, a satellite network portal and a user terminal use a satellite handoff information to determine when to handoff the user terminal from one cell to another and/or from one satellite to another. In some aspects, a user terminal sends capability information, location information, or other information to a satellite network portal whereby, based on this information, the satellite network portal generates the satellite handoff information and/or selects a handoff procedure for the user terminal. In some aspects, handoff of a user terminal to a different satellite involves the user terminal conducting satellite signal measurements and sending a measurement message to the satellite network portal. In some aspects, the satellite network portal generates new satellite handoff information as a result of receiving a measurement message.
