Some implementations of the disclosure relate to dynamic switching of a satellite inroute data path between a Time Division Multiple Access (TDMA) method and a Time Division Multiplexing (TDM) method. In one implementation, a satellite terminal comprises one or more processors; and one or more non-transitory computer-readable storage media configured with instructions executable by the one or more processors to cause the satellite terminal to perform operations comprising: communicating, using the satellite terminal, over an inroute TDM channel; determining, based on an ingress traffic rate to the satellite terminal or a determination that the satellite terminal has not received any traffic flows classified for communication using TDM, to switch communications from the inroute TDM channel to an inroute TDMA channel; and after determining to switch communications, switching, at the satellite terminal, from communicating over the inroute TDM channel to communicating over the inroute TDMA channel.

Dynamic switching of satellite inroute data path between a time-division multiple access method and a time division multiplex method

Some implementations of the disclosure relate to dynamic switching of a satellite inroute data path between a Time Division Multiple Access (TDMA) method and a Time Division Multiplexing (TDM) method. In one implementation, a method comprises: communicating, using a satellite terminal, over an inroute TDMA channel; determining, at the satellite terminal, based at least on an aggregate ingress traffic rate to the satellite terminal, to switch communications from the inroute TDMA channel to an inroute TDM channel; and after determining to switch communications, sending, from the satellite terminal to a Gateway Earth Station, a request to be allocated an inroute TDM channel.

A first computer that includes a processor and memory storing instructions executable by the processor&#x2014;the processor is programmed to: establish a satellite link between a satellite terminal and the first computer, the link comprising at least one radio access bearer (RAB); receive a rejection message from a second computer indicating that the second computer refuses to accept a terminal handover; and in response to receiving the rejection message, transmit to the second computer a pending handover request message comprising an indication of a link quality of the at least one RAB.

Delayed satellite handover

A system and method are disclosed for admission control of mobile conversational user sessions by a satellite network is described. When a request to admit a new session over a satellite network is received, the radio access bearer setup request is transmitted to a remote terminal of the satellite network. The system determines if a requested guaranteed bit rate for the new session is available from the remote terminal. If the requested guaranteed bit rate is available, the terminal forwards the request to a gateway of the satellite network. The new session is subsequently admitted over the satellite network and allocated the requested guaranteed bit rate.
