Abstract
An emergency handoff method (50) reroutes or redirects communications from one channel in a cell (105) to another channel in the same cell (105) or a different cell (107). Handoff is initiated by a subscriber unit (SU) (100) when the SU (100) determines that an emergency handoff is needed. Once a new channel is needed, the SU (100) chooses a new, available channel to transfer its communication. After selecting an available channel, the SU (100) acquires the available channel. The servicing satellite which is providing the available channel then makes the constellation of satellites reroute or redirect the call data or the communication packets across the new channel to the SU (100).
