Abstract: The present invention provides a medium access control (MAC) layer in a mobile satellite system. The MAC transfers data across the physical channels in the air interface between the mobile terminals, the satellite and the gateways. The MAC of the present invention optimizes for satellite propogation delays and hides the physical transmission media from higher network layers.

Abstract: An approach for is provided for adapting to a variety of link propagation conditions is disclosed. A source terminal generates a packet data burst that includes a header and an optional payload. The header is modulated using a default modulation scheme and is coded using a default coding scheme. A switch is configured to receive and to forward the packet data burst. A destination terminal is configured to demodulate the header using the default modulation scheme and the default coding scheme, and to examine the header to determine a particular coding scheme and a particular modulation scheme associated with the payload. The protocol can be applied to any radio communication system, particularly, to a satellite communication system with multiple satellite terminals.

Abstract: An integrated PCN/DCN system architecture has a switching center, coupled to a public switched telephone network (PSTN), which selectively transfers signals between the PSTN and a digital cellular network (DCN) or a personal communications network (PCN) which is allocated a portion of the cellular communications band by a local cellular operator. Each PCN subnetwork of the PCN includes several microcells arranged in a multi-dimensional grid, and the allocated cellular channels are divided into sets assigned to columns of the grid. The allocated portion of the cellular spectrum is reused within each PCN subnetwork by assigning the same set to more than one of the columns so that different communications signals can be transferred over the same cellular channels.
