ABSTRACT:
A method and apparatus for autonomous assignment of communications channels during call handoffs by a user terminal in a satellite-based telecommunications system. The method comprises the steps of transmitting a request for access from a user terminal to a control center via at least one satellite and selecting channel parameters and model assignment information for a first communications channel at the control center. The assignment information identifies predictable events which require the first user terminal to switch to a second communications channel. The channel parameters and model assignment information are transmitted from the control center to the first user terminal. A communications link is established over a first channel with the first user terminal. While the communications link with the first user terminal over the first channel is maintained, the user terminal autonomously switching its communications link to a second communications channel based on model assignment information identifying a predictable event preventing the first user terminal from continuing to use the first communications channel.
