System for distributed management of satellite uplink communication

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. Contentio...

More Information
Summary: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. Contention for the uplink may be managed by sending grants that allocate a portion of the uplink time and frequency resources to individual UTs. A UT serviced by the satellite uses information based on the grants to determine whether upstream data from a user device connected the UT should be accepted for future transmission promised to deliver specified quality of service to the user device. Acting as a distributed system, each UT may decide to approve upstream data based on one or more factors, such as source address, destination address, header flags, predicted radio availability, and so forth.
