Enhanced mobile base station
View Patent ↗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.
1. A mobile base station, comprising:
a processor configured to provide a cellular base station functionality;
a first access radio electrically coupled to the processor for providing a cellular access network inside and outside a vehicle;
a first cellular backhaul radio electrically coupled to the processor for providing a backhaul connection to a cellular network via a cell; and
a global positioning system (GPS) module electrically coupled to the processor for determining a location of the mobile base station,
wherein the processor is configured to transmit the location of the mobile base station to the cellular network, disable the first access radio for providing the cellular access network outside the vehicle when the vehicle is in motion, and enable the first access radio when the vehicle is stationary with a power level determined using a self-organizing network (SON) algorithm.
2. The mobile base station of claim 1 , wherein the mobile base station is an eNodeB, wherein the first cellular backhaul radio is a Long Term Evolution (LTE) radio, and wherein the cellular access network is an LTE cellular access network.
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 second access radio for providing a second access network, the first and second access radios being configured to provide access network 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 first 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 first 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. The mobile base station of claim 1 , wherein the processor is further configured to enable a Wi-Fi mesh radio when the vehicle is stationary for near-field or local communications.
