Abstract: A satellite provides communication between user terminals (UTs) and ground stations that connect to other networks, such as the Internet. Because the satellite is within range of many UTs at any given time, many UTs are in contention to use an uplink to send upstream data to the satellite. This saturates a random-access channel (RACH) on the uplink. When a UT has data to uplink, it sends a short buffer data status (SBDS) message using the RACH. The minimal size of the SBDS facilitates use of a non-orthogonal multiple access uplink. Based on the SBDS, the satellite allocates a grant to the UT to use the uplink. Additional messages from the UT involving buffer status may be sent using the granted uplink. Unsolicited grants may be issued to the UT based on analysis of uplink and downlink traffic. If needed, the RACH may still be used to request additional grants.

Abstract: Systems and methods for transmitting data using a satellite communication network are disclosed herein. In an embodiment, a satellite communication network includes a first terminal, a second terminal, and a base station. The first terminal is configured to collect first target data. The second terminal is configured to receive a first data packet including the first target data from the first terminal via a local connection. The base station is in communication with the first terminal and the second terminal via at least one satellite. The base station is configured to: (i) receive copies of the first data packet from each of the first and second terminals via the at least one satellite; (ii) process a first copy of the first data packet; and (iii) delete a second copy of the first data packet.

Abstract: Systems and methods are provided to achieve dynamic bandwidth allocation among terminal groups (TGs) with proportional fairness in terms of both throughput and spectrum usage across a network. Quality of service (QoS) metrics for such TGs can be satisfied in terms of maximum throughput and spectrum utilization, while also satisfying QoS metrics such as latency, throughput, and prioritized traffic services for individual terminals within the TGs. A centralized bandwidth manager can be utilized to manage such dynamic bandwidth allocation across multiple Code Rate Organizers (CROs), including environments in which the multiple CROs manage communications across multiple IPGWs for multiple terminal groups. Because, in such environments, a given conventional CRO cannot effectively manage allocations across the entire network, the centralized bandwidth management functionality can be introduced to assess the flows for multiple TGs across multiple CROs and to make bandwidth allocations accordingly.

Abstract: Systems and methods provide bandwidth management on the inroute of a satellite network. Inroute group managers (IGMs) monitor bandwidth usage in each terminal group (TG) under each of the IGMs, and report this bandwidth usage to a bandwidth manager. Upon receipt of the reported bandwidth usage from each of the IGMs, the bandwidth manager compares the bandwidth usage and minimum/maximum throughput rates associated with each TG. The bandwidth manager calculates scaling factors that it transmits to each of the IGMs to allow the IGMs to allocate bandwidth accordingly.

Abstract: An approach is provided for the application of network acceleration technologies to remote node traffic over GPRS tunneling protocols (GTP) in terrestrial mobile communications networks. A proxy device of a first network node receives a stream of data packets that are encapsulated in accordance with GTP. Each GTP packet is de-encapsulated by stripping GTP header from the packet, identifying the TEID (reflecting a respective GTP flow with which the GTP packet is associated), and maintaining a respective GTP payload (PDU). Acceleration functions are applied to the GTP PDUs, and the resulting acceleration packets are transmitted communications network link(s) to a proxy of a second network node. The second node proxy device receives the transmitted packets, and re-encapsulates each packet, in accordance with the GTP protocol, based at least in part on the respective TEID of the packet.
