Abstract
A first computer that includes a processor and memory storing instructions executable by the processor—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.
Claims19
A first computer, comprising a processor and memory storing instructions executable by the processor, the processor 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,
- wherein the first computer is a source radio network controller for satellite (RNCS), wherein the second computer is a target radio network controller for satellite (RNCS).
A system, comprising:
- a first computer, comprising a processor and memory storing instructions executable by the processor, the processor programmed to:
- receive via an Iur interface, from at least one second computer, one or more satellite terminal handover request messages, wherein each of the one or more messages includes an indication of link quality of at least one radio access bearer (RAB) connection;
- select one of the one or more messages based on the indication of the link quality of the at least one RAB connection;
- and
- based on the selection, transmit an acceptance message to the at least one second computer.
A satellite base station, comprising:
- a first computer communicating with a satellite terminal via a satellite link and having at least one radio access bearer (RAB);
- and
- a second computer coupled to the first computer via a radio network controller interface,
- wherein the first computer is programmed to transmit a message to the second computer, via the radio network controller interface, regarding a handover of the satellite terminal, wherein the message includes an indication of a link quality associated with the at least one RAB,
- wherein the second computer is programmed to, upon receiving the message:
- queue the message;
- compare the indication of the link quality of the at least one RAB with other link quality indications of other RABs associated with other queued messages also received by the second computer;
- release at least one RAB currently serviced by the second computer;
- and
- accept a handover of the satellite terminal based on the indication of the link quality.
