Abstract
In a satellite-based messaging system messages are exchanged between a ground station and mobile terminals over a wide geographic area covered by multiple satellite beams. Each beam contains one or more carrier frequencies. A message processing center is configured to provision a frame comprising a plurality of subframes to carry data over a forward link to the mobile terminals; hop between beams in the forward link and assign each subframe within a frame to a specific satellite beam; provision a transport medium in the form of virtual carriers each defined by one or more carrier frequency/beam hop combinations, wherein each virtual carrier is assigned a unique virtual carrier identifier; and notify the mobile terminals of carrier frequency/hop combinations for assigned virtual carrier identifiers.
