摘要： A system and method of controlling communication between a satellite transceiver and a ground transceiver, where the satellite transceiver is configured to receive concurrently a plurality of messages at substantially the same carrier frequency from a plurality of ground transceivers. The satellite transceiver transmits a ranking threshold indicative of a transceiver ranking of a ground transceiver that authorizes the ground transceiver to transmit a message to the satellite transceiver. The ground transceiver receives the ranking threshold transmitted by the ground transceiver, and determines if the ground transceiver is authorized to transmit a message based on a comparison of the ranking threshold and a transceiver ranking of the ground transceiver.

摘要： Satellite communications systems, methods, and related devices are described. In one embodiment, a satellite communications system is configured to dynamically allocate bandwidth and frequencies among different beams. Bandwidth request data may be received and compiled from the terminals. The satellite may be configured with different beam coverage areas, and may dynamically allocate bandwidth and particular frequency channels to different beam coverage areas based on the requests. In each of a series of one or more epochs, and according to the bandwidth requests, there may be allocations among carrier groups, traffic classes, and particular terminals. The setup of slot structure and selection of modes for particular terminals is also addressed.

摘要： In a bandwidth allocation protocol for a mobile communications network, mobile terminals report their bandwidth requirements to the network, while the network controls the amount of bandwidth that is used by the mobiles in reporting their bandwidth requirements. The mobiles indicate the total quantity of data awaiting transmission, the maximum delay time of the most urgent portion of the data and the maximum delay time of the least urgent portion. If a collision occurs between transmission by two mobiles, the mobiles wait for an interval controlled by the network before attempting another contention-based access transmission. The network periodically varies the contention-based access capacity available according to the observed usage level and/or collision rate in the previously allocated contention-based access capacity. The network analyses the forward traffic to individual mobiles and predicts the return bandwidth requirements which are likely to result from the forward traffic. The network stores associations between forward and return frequency channels, so that when a mobile receiving a forward frequency channel request return capacity, the network preferentially assigns return bandwidth to the mobile in one or more of the associated return channels.

摘要： A mobile wireless communications system including a plurality of individual transponding nodes of various types, all in communication with a central processing hub. A local user signal is processed by the central processing hub and radiated through multiple paths to a plurality of the plurality of individual transponding platforms simultaneously. The signal is then re-radiated by each of the plurality of the plurality of individual transponding platforms to a mobile terminal that receives the re-radiated signal from the plurality of the plurality of individual transponding platforms coherently and in phase. The number of transponders and codes used to transmit each user signal can be readily adapted to user requirements. Additionally, each user is assigned a profit value by the central processing hub depending upon certain user characteristics. The assigned user profit value allows the total system utility/profitability to be maximized.
