Abstract

Systems and methods for an in-vehicle base station are described. In one embodiment, a method is disclosed, comprising: permitting a mobile device to attach to the mobile base station; attaching, at the mobile base station, to a macro cell for providing backhaul to the mobile device using the mobile base station for access; receiving a first tracking area code from the macro cell; transmitting a second tracking area code to the mobile device, the second tracking area code corresponding to a tracking area managed by a coordinating node; detecting, at the mobile base station, a transition from a stationary state to a moving state of the mobile base station; and sending a tracking area update message to a core network to transition to the tracking area managed by the coordinating node.

Claims

1. A method, comprising:

at a processor configured to provide a cellular base station functionality, the processor being part of a mobile base station, the processor coupled to a first access radio for providing a cellular access network inside and outside a vehicle, the processor further coupled to a first cellular backhaul radio for providing a backhaul connection to a cellular network via a cell, the processor further coupled to a global positioning system (GPS) module for determining a location of the mobile base station;

permitting a mobile device to attach to the mobile base station;

attaching, at the mobile base station, to a macro cell for providing backhaul to the mobile device using the mobile base station for access;

receiving a first tracking area code from the macro cell;

transmitting a second tracking area code to the mobile device, the second tracking area code corresponding to a tracking area managed by a coordinating node;

detecting, at the mobile base station, a transition from a stationary state to a moving state of the mobile base station; and

sending a tracking area update message to a core network to transition to the tracking area managed by the coordinating node,

thereby avoiding unnecessary tracking area updates for the mobile device.

2. The method of claim 1, further comprising performing paging of the mobile device using the second tracking area code.

3. The method of claim 1, further comprising detecting the location of the mobile base station using the GPS module, and sending the location to the coordinating node.

4. The method of claim 1, further comprising detecting a location of the mobile device based on the location of the mobile base station.

5. The method of claim 1, further comprising coordinating, using a self-organizing network (SON) algorithm, a handover between multiple tracking areas.

6. The method of claim 1, further comprising updating a tracking area of the mobile base station at a mobility management entity (MME).

7. The method of claim 1, further comprising updating a tracking area of the mobile device at the coordinating node, the coordinating node being situated between the mobile base station and a mobility management entity (MME).

8. The method of claim 1, further comprising updating a tracking area of the mobile device at a mobility management entity (MME) using the location of the mobile base station.

9. A non-transitory computer-readable medium storing one or more instructions that, when executed by one or more processors, cause the one or more processors to:

permit a mobile device to attach to the mobile base station;

attach at the mobile base station, to a macro cell for providing backhaul to the mobile device using the mobile base station for access;

receive a first tracking area code from the macro cell;

transmit a second tracking area code to the mobile device, the second tracking area code corresponding to a tracking area managed by a coordinating node;

detect at the mobile base station, a transition from a stationary state to a moving state of the mobile base station; and

send a tracking area update message to a core network to transition to the tracking area managed by the coordinating node,

thereby avoiding unnecessary tracking area updates for the mobile device.

10. The non-transitory computer-readable medium of claim 9, wherein the one or more processors are configured to perform paging of the mobile device using the second tracking area code.

11. The non-transitory computer-readable medium of claim 10, wherein the one or more processors are configured to detect the location of the mobile base station using the GPS module, and send the location to the coordinating node.

12. The non-transitory computer-readable medium of claim 10, wherein the one or more processors are configured to detect the location of the mobile device based on the location of the mobile base station.

13. The non-transitory computer-readable medium of claim 10, wherein the one or more processors are configured to coordinate using a self-organizing network (SON) algorithm, a handover between multiple tracking areas.

14. The non-transitory computer-readable medium of claim 10, wherein the one or more processors are configured to update the tracking area of the mobile base station at a mobility management entity (MME).

15. The non-transitory computer-readable medium of claim 10, wherein the one or more processors are configured to update the tracking area of the mobile device at the coordinating node, the coordinating node being situated between the mobile base station and a mobility management entity (MME).

16. The non-transitory computer-readable medium of claim 10, wherein the one or more processors are configured to update the tracking area of the mobile device at a mobility management entity (MME) using the location of the mobile base station.
