1. In a satellite communication system, a method comprising steps of:
- allocating for control a first portion of a pool of slots within a return channel;
allocating for data a second portion of the pool of slots, wherein the second portion is accessible by circuit-switched TDM allocations, reservation allocations, and random access.

Abstract
Efficient utilization of a shared pool of time-frequency slot resources in a return channel among a plurality of remote terminals in a satellite communication system. Within the shared pool of time-frequency slot resources for data, allowing access through circuit-switched TDM allocations, reservation allocations, or random access. Within the shared pool of time-frequency resources for control, allowing duplicate control burst transmissions in random access. Other improvements in the control channel include self-allocation by the remote terminals or hub-allocation to the remote terminals.

- 17. A remote terminal configured to communicate with a satellite system including a plurality of other remote terminals, the remote terminal configured to transmit over a return channel shared with the other remote terminals, the return channel including a control portion and a data portion, wherein the remote terminal is configured to transmit over the data portion through circuit-switched TDM allocations, reservation allocations, and random access.
- 23. A remote terminal configured to communicate with a satellite system including a plurality of other remote terminals, the remote terminal configured to transmit over a return control channel shared with the other remote terminals, wherein the remote terminal is configured to access the return control channel using random access and allocated access.

30. In a satellite communication system, a method comprising steps of:
-
allocating a first subset of slots from a single pool of slots using reservation allocations and circuit-switched TDM allocations; and
making available a second subset of slots from the single pool of slots for control random access and data random access.
