Abstract

Systems and methods for operating a satellite terminal for a multi-band hybrid satellite communication system include receiving a configuration file for a satellite terminal for the satellite communication system; determining frequency band(s) supported by the satellite terminal from the configuration file; automatically selecting a best available outroute that is compatible with the frequency band(s) supported by the satellite terminal even if the best available outroute is not an anchor route listed in the configuration file; and performing a commissioning process to connect the satellite terminal to a satellite associated with the best available outroute.

First claim

What is claimed is:

1 . A data processing device for a multi-band hybrid satellite communication system, the data processing device comprising:
a processor; and a memory in communication with the processor, the memory comprising executable instructions that, when executed by the processor alone or in combination with other processors, cause the processor to perform functions of:
receiving a configuration file for a satellite terminal for the satellite communication system;
determining frequency band(s) supported by the satellite terminal from the configuration file;
automatically selecting a best available outroute that is compatible with the frequency band(s) supported by the satellite terminal even if the best available outroute is not an anchor route listed in the configuration file;
performing a commissioning process to connect the satellite terminal to a satellite associated with the best available outroute.

2 . The data processing device of claim 1 , wherein the functions further comprise:
receiving an outroute advertisement from a gateway, the outroute advertisement identifying all outroutes in a spot beam and frequency band(s) supported by each of the outroutes; and automatically selecting the best available outroute based on the outroute advertisement.

3 . The data processing device of claim 2 , wherein, when the satellite terminal is a multi-band terminal and the terminal is in a beam overlap area including at least one single band beam and at least one multi-band beam, the best available the outroute is selected based in part on a multi-band weighting factor that biases outroute selection toward multi-band beams.

4 . The data processing device of claim 2 , wherein the functions further comprise:
performing a link adaptation process that includes:
monitoring a fade level of a current selected outroute; and
when the fade level is greater than a fade threshold, switching the satellite terminal to another outroute for a different frequency band.

5 . The data processing device of claim 4 , wherein the functions further comprise:
biasing switching of multi-band terminals from outroutes of a first frequency band to outroutes of a second frequency band when the fade level of the outroutes of the first frequency band falls below the fade threshold.

6 . The data processing device of claim 1 , wherein selecting the best available outroute for the satellite terminal from the other outroutes available to the satellite terminal further comprises:
displaying a list of outroutes on a display screen associated with the satellite terminal, wherein the list of outroutes includes only outroutes for frequency bands that are compatible with the frequency band(s) supported by the satellite terminal.

7 . The data processing device of claim 6 , wherein the functions further comprise:
receiving a user input that indicates a selection of one of the outroutes in the list; and performing the commissioning process to connect the satellite terminal to the outroute indicated by the user input.

8 . The data processing device of claim 1 , wherein an installation quality verification process is performed to determine quality metrics for a first outroute for a first frequency band and a second outroute for a second frequency, and
wherein the best available outroute is selected based on the quality metrics.

9 . The data processing device of claim 1 , wherein the satellite terminal comprises a mobile terminal, and
wherein the functions further comprise:
when entering a coverage area of a single band spot beam, performing a look ahead process, the look ahead process including:
determining whether a multi-band spot beam will be reached within a predetermined waiting time;
when a multi-band spot beam can be reached within the predetermined waiting time:
waiting until the mobile terminal reaches the multi-band spot beam without switching to the first spot beam; and
once the multi-band spot beam is reached, performing a beam switching process to connect to the satellite that produces the multi-band capable spot beam; and

when a multi-band spot beam cannot be reached within the predetermined waiting time:
performing the beam switching process to connect to a satellite associated with the single band spot beam.

10 . A method for operating a satellite terminal for a multi-band hybrid satellite communication system, the method comprising:
receiving a configuration file for a satellite terminal for the satellite communication system; determining frequency band(s) supported by the satellite terminal from the configuration file; automatically selecting a best available outroute that is compatible with the frequency band(s) supported by the satellite terminal even if the best available outroute is not an anchor route listed in the configuration file; and performing a commissioning process to connect the satellite terminal to a satellite associated with the best available outroute.

11 . The method of claim 10 , further comprising:
receiving an outroute advertisement from a gateway, the outroute advertisement identifying all outroutes in a spot beam and frequency band(s) supported by each of the outroutes; and automatically selecting the best available outroute based on the outroute advertisement.

12 . The method of claim 11 , wherein, when the satellite terminal is a multi-band terminal and the terminal is in a beam overlap area including at least one single band beam and at least one multi-band beam, the best available outroute is selected based in part on a multi-band weighting factor that biases outroute selection toward multi-band beams.

13 . The method of claim 10 , wherein selecting a compatible outroute for the satellite terminal from the other outroutes available to the satellite terminal further comprises:
displaying a list of outroutes on a display screen associated with the satellite terminal, wherein the list of outroutes includes only outroutes for frequency bands that are compatible with the frequency band(s) supported by the satellite terminal.

14 . The method of claim 13 , further comprising:
receiving a user input identifying one of the outroutes from the list of outroutes as the best available outroute.

15 . The method of claim 10 , wherein an installation quality verification process is performed to determine quality metrics for a first outroute for a first frequency band and a second outroute for a second frequency, and
wherein the best available outroute is selected based on the quality metrics.

16 . The method of claim 10 , wherein the satellite terminal comprises a mobile terminal, and
wherein the method further comprises:
when entering a coverage area of a single band spot beam, performing a beam switching process that includes:

performing a look ahead process, the look ahead process including:
determining whether a multi-band spot beam will be reached within a predetermined waiting time;
when a multi-band spot beam can be reached within the predetermined waiting time:
waiting until the multi-band spot beam is reached without switching to the first spot beam; and
once the multi-band spot beam is reached, performing a beam switching process to connect to the satellite associated with the multi-band spot beam; and

when a multi-band spot beam cannot be reached within the predetermined waiting time:
performing the beam switching process to connect to a satellite associated with the single band spot beam.

17 . The method of claim 10 , further comprising:
performing a link adaptatio
