Abstract

A mobile small station including a transceiver, a processor, and a memory having instructions for execution by the processor to exchange measurement information with a macro station, provide a wide area network connection and act as a relay for a small station moving network with the mobile small station, and perform handover of relay responsibilities to another mobile small station in the small station moving network.

First claim

The invention claimed is:

1. At least one non-transitory machine readable medium including instructions that, when executed by a machine, configure the machine to:
provide a relay for member mobile small stations, the member mobile small stations moving with the machine and part of a small station moving network;
exchange measurement information with the member mobile small stations with respect to a macro station;
compare the exchanged measurement information over time to determine a collective speed and direction of the member mobile small stations, wherein the measurement information is signal strength, wherein the collective speed and direction are determined by changes over time to the signal strength with respect to the macro station across the member mobile small stations, and wherein the collective speed and direction are an average speed and direction of movement common to all member mobile stations;
forward a page from the macro station to a mobile small station of the small station moving network, the page including information to shorten radio resource connection (RRC) setup between the mobile small station and the macro station, the mobile small station selected based on the collective speed and direction of the member mobile stations determined by comparing the exchanged measurement information; and
perform a handover of relay responsibilities to the mobile small station of the small station moving network based on the collective speed and direction of the member mobile stations determined by comparing the exchanged measurement information.

2. The at least one machine readable medium of claim 1 wherein the measurement information is also exchanged with other mobile small stations in the small station moving network.

3. The at least one machine readable medium of claim 2 wherein the instructions further cause the machine to compare exchanged measurement information to determine an order of the small station moving network.

4. The at least one machine readable medium of claim 1 , wherein the instructions further cause the machine to:
detect a potential necessity to perform a handover; and
define an optimum point in time for the handover, wherein the optimum point in time for the handover is defined as a point in time when a signal from a current relay is decreasing while a signal from a potential new relay is increasing, and such signals are equal and providing an acceptable quality of service.

5. The at least one machine readable medium of claim 1 wherein the handover of relay responsibilities is performed before signal degradation adversely affects the relay.

6. A mobile small station comprising:
a transceiver;
a processor; and
a memory having instructions for execution by the processor to:
provide a relay for member mobile small stations, the member mobile small stations moving with the machine and part of a small station moving network;
exchange measurement information with the member mobile small stations with respect to a macro station;
compare the exchanged measurement information over time to determine a collective speed and direction of the member mobile small stations, wherein the measurement information is signal strength, wherein the collective speed and direction are determined by changes over time to the signal strength with respect to the macro station across the member mobile small stations, and wherein the collective speed and direction are an average speed and direction of movement common to all member mobile stations;
forward a page from the macro station to a second mobile small station of the small station moving network, the page including information to shorten radio resource connection (RRC) setup between the second mobile small station and the macro station, the second mobile small station selected based on the collective speed and direction of the member mobile stations determined by comparing the exchanged measurement information; and
perform a handover of relay responsibilities to the second mobile small station of the small station moving network based on the collective speed and direction of the member mobile small stations determined by comparing the exchanged measurement information.

7. The mobile small station of claim 6 wherein the measurement information is also exchanged with other mobile small stations in the small station moving network.

8. The mobile small station of claim 6 wherein the instructions further cause the processor to compare exchanged measurement information to determine an order of the small station moving network.

9. The mobile small station of claim 8 wherein the instructions further cause the processor to:
detect a potential necessity to perform a handover; and
define an optimum point in time for the handover.

10. The mobile small station of claim 9 wherein the optimum point in time for the handover is defined as a point in time when a signal from a current relay is decreasing while a signal from a potential new relay is increasing, and such signals are equal and providing an acceptable quality of service.

11. The mobile small station of claim 6 wherein the mobile small station is coupled to the small station moving network via a wire.

12. The mobile small station of claim 6 wherein the mobile small station is coupled to the small station moving network wirelessly.

13. At least one non-transitory machine readable medium including instructions that, when executed by a machine, configure the machine to:
provide a wide area network connection via a mobile small station to act as a relay for a small station moving network;
obtain measurement information over time from mobile small stations in the small station moving network to determine a collective speed and direction of the mobile small stations, wherein the measurement information is signal strength, wherein the collective speed and direction are determined by changes over time to the signal strength with respect to a macro station across the mobile small stations, and wherein the collective speed and direction are an average speed and direction of movement common to all member mobile stations;
forward a page from the macro station to a second mobile small station of the small station moving network, the page including information to shorten radio resource connection (RRC) setup between the mobile small station and the macro station, the mobile small station selected based on the collective speed and direction of the member mobile stations determined by comparing the exchanged measurement information; and
hand over relay responsibilities to the second mobile small station in the small station moving network based on the determined collective speed and direction of the mobile small stations.

14. The at least one machine readable medium of claim 13 wherein the measurement information is also exchanged with other mobile small stations in the small station moving network.

15. The at least one machine readable medium of claim 14 , wherein the instructions further cause the machine to compare exchanged measurement information from multiple mobile small stations to determine an order of the mobile small stations in the small station moving network.

16. The at least one machine readable medium of claim 15 , wherein the instructions further cause the machine to:
detect a potential necessity to perform a hand over; and
define an optimum point in time for the handover.

17. The at least one machine readable medium of claim 13 wherein the instructions cause the machine to hand over relay responsibilities before signal degradation adversely
