Abstract

Systems and methods for an in-vehicle base station are described. In one embodiment, a mobile base station is disclosed comprising a first access radio for providing an access network inside and outside a vehicle; a second backhaul radio for providing a backhaul connection to a macro cell; and a global positioning system (GPS) module for determining a location of the mobile base station, and for transmitting the location of the mobile base station to a core network, wherein a transmit power of the first access radio is configured to increase or decrease based on a speed of the vehicle.

Claims

1. A mobile base station, comprising:

a first access radio for providing an access network inside and outside a vehicle;

a second backhaul radio for providing a backhaul connection to a macro cell; and

a global positioning system (GPS) module for determining a location of the mobile base station, and for transmitting the location of the mobile base station to a core network,

wherein a transmit power of the first access radio is configured to increase or decrease based on a speed of the vehicle.

2. The mobile base station of claim 1, wherein the mobile base station is an eNodeB.

3. The mobile base station of claim 1, wherein the mobile base station is affixed to one of a car, a truck, a van, a trailer, a plane, a boat, a drone, or a balloon.

4. The mobile base station of claim 1, further comprising a third access radio for providing a second access network, the first and third access radios being configured to provide access networks using a Long Term Evolution (LTE) air interface and a Wi-Fi air interface, respectively.

5. The mobile base station of claim 1, wherein the speed of the vehicle is determined based on either the GPS module or a vehicle controller access network (CAN) bus.

6. The mobile base station of claim 1, wherein the mobile base station is configured to use the second backhaul radio to communicate with a coordinating node for determining a transmit power of the first access radio.

7. The mobile base station of claim 1, wherein the mobile base station is configured to use the second backhaul radio to receive an appropriate power level, a directionality of broadcast power, a neighbor list, or a tracking area list from a coordinating node.

8. The mobile base station of claim 1, further comprising a tablet connected to the first access radio, the mobile base station being configured to permit the tablet to access and reconfigure the mobile base station.

9. A method, comprising:

broadcasting, at an in-vehicle base station, an access network at a first power;

detecting a transition from a stationary state to a moving state of the in-vehicle base station;

reducing a transmit power of the in-vehicle base station while in the moving state; and

increasing the transmit power of the in-vehicle base station when exiting the moving state.

10. The method of claim 9, further comprising communicating with a coordinating node for determining the transmit power of the in-vehicle base station while in the moving state.

11. The method of claim 9, further comprising receiving, from a vehicle controller area network (CAN) bus, one of a vehicle ignition turn-on indication, an engine turn-off indication, a vehicle electrical power activation indication, a vehicle electrical power deactivation indication, an accelerometer indication, or a vehicle gear shift indication;

and using the indication from the CAN bus to determine the transmit power.

12. The method of claim 9, further comprising receiving, from a coordinating node in a core network, an appropriate power level, a directionality of broadcast power, a neighbor list, or a tracking area list.

13. A method, comprising:

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

receiving a first tracking area code from the macro cell;

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

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 a 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 a coordinating node,

thereby avoiding unnecessary tracking area updates for the mobile device.

14. The method of claim 13, further comprising performing paging of the mobile device using the second tracking area code.

15. The method of claim 13, further comprising detecting the location of the base station using a global positioning system (GPS) module, and sending the location to the coordinating node.

16. The method of claim 15, further comprising detecting the location of the mobile device based on the location of the base station.
