Power Management for Vehicle-Mounted Base Station
First Claim
1. A base station for providing dynamic power management, comprising:
- a processor within an enclosure mounted in a vehicle;
a power management unit coupled to the processor;
a controller area network (CAN) bus monitoring system coupled to the power management unit and to a CAN bus of the vehicle;
a voltage measurement module also coupled to the power management unit and to a battery of the vehicle;
a baseband processor coupled to the processor;
a first wireless access functionality coupled to the baseband processor; and
a second wireless access functionality coupled to the baseband processor,wherein the power management unit is coupled to each of the first and the second wireless access functionality to enable access radio bringup, access radio shutdown, and graceful user detach based on a power state at the power management unit.

15. A method for dynamic power management of an in-vehicle base station, comprising:
-
monitoring a vehicle controller area network (CAN) bus of a vehicle for power-related messages; monitoring a positioning sensor to determine a location of the vehicle; monitoring a voltage of an electrical circuit in the vehicle to determine a power management state; and conducting an orderly shutdown of radio frequency services based on the power-related messages, the location of the vehicle, and the power management state. - View Dependent Claims (16, 17)

18. A method for bringup of an in-vehicle base station, comprising:
-
powering on a base station in a vehicle; identifying a power management state of the vehicle; searching for mesh nodes to provide a connection for the base station; activating a Long Term Evolution (LTE) user equipment (UE) coupled to the base station; attempting to connect to an LTE network using the LTE UE; applying a configuration from a mesh node, an LTE network, or a radio frequency environment discovered by the UE; and based on the applied configuration and based on the power management state of the vehicle, determining whether to activate a radio frequency access network. - View Dependent Claims (19)
