Abstract
Method and apparatus for dynamically optimizing the transmission level of each remote terminal in a satellite-based communication network. Each remote terminal maintains quasi-error-free communication at the highest efficiency level available under changing link conditions and network configurations, without requiring the reservation of substantial power margins, which results in a much more efficient satellite network.
Claims14
A terminal device in a satellite-based communication system, comprising at least one processor and memory, wherein the terminal device is configured to:
- transmit a plurality of maintenance packets to a hub in the satellite-based communication system, at a first transmit power level;
- receive one or more reply packets containing reception level measurements for one or more of the maintenance packets transmitted at the first transmit power level;
- calculate an average reception level for the maintenance packets transmitted at the first transmit power level;
- determine a satellite transmitter input power level;
- and
- calculate a gain equivalent value based on the average reception level at the first transmit power level and the determined satellite transmitter input power level.
A satellite-based communication system comprising:
- a hub configured to communicate via satellite with one or more remote terminals;
- and
- one or more remote terminals, each of said remote terminals is configured to:
- determine a maximal transmit power level for transmitting data to the hub;
- transmit one or more maintenance packets to the hub at a first transmit power level, wherein each said maintenance packet includes an information item containing a difference between the first transmit power level and the maximal transmit power for transmitting data to the hub.
A satellite-based communication system, comprising:
- one or more remote terminals and a hub,
- each of said remote terminals being configured to:
- transmit maintenance packets via satellite to the hub, and
- the hub being configured to:
- receive the maintenance packets transmitted by the one or more remote terminals;
- measure the reception level of the maintenance packets received from the one or more remote terminals;
- identify a plurality of different timeslot types in a return link of the satellite-based communication network, wherein each of the one or more remote terminals is associated with one or more of the different timeslot types;
- and
- based on the measured reception levels of the maintenance packets, configure communications with the one or more remote terminals such that each remote terminal is allocated to a timeslot type.
