Burst level resources allocation on the up/down link in a low Earth orbit satellite constellation

The up/down link UDL of a low Earth orbit LEO satellite constellation is a scarce resource that needs to be shared efficiently between different users with different needs. Serving requests at the call level appears to be bandwidth wasteful since resources are still allocated to a communication even during silence periods. A burst level service appears to be a more appropriate one in order to increase resources utilization. In the context of this study, three service classes are considered: voice service, a real time service with very strict constraints over the delay and the bandwidth, data service with guarantees but with less stringent requirements than what is required for voice, and best effort service with no guarantees requirements. A new form of movable boundary approach is used in order to accommodate a greater number of communications of each class, while respecting quality of service QoS requirements.
