Abstract

A mobile base station is disclosed, comprising: a vehicle bus notification module; an access interface for communicating with a mobile device; a backhaul interface for communicating with an operator core network; and a processor, in communication with the vehicle bus notification module, the access interface, and the backhaul interface, further comprising instructions that, when executed by the processor, perform steps comprising: receiving a vehicle bus low power alert at the vehicle bus notification module; and sending a message via the backhaul interface to the operator core network to request a notification to be sent to the mobile device regarding power off of the mobile base station.

Claims

1. A mobile base station, comprising:

a vehicle bus notification module;

an access interface for communicating with a mobile device;

a backhaul interface for communicating with an operator core network; and

a processor, in communication with the vehicle bus notification module, the access interface, and the backhaul interface, further comprising instructions that, when executed by the processor, perform steps comprising;

receiving a vehicle bus low power alert at the vehicle bus notification module; and

sending a message via the backhaul interface to the operator core network to request a notification to be sent to the mobile device regarding power off of the mobile base station.

2. A method, comprising:

receiving, at an in-vehicle base station, a low power alert from a vehicle controller network;

sending, at the in-vehicle base station, a request to a network server to message mobile devices attached to the in-vehicle base station informing the mobile devices that the in-vehicle base station will be powering down; and

sending, from the network server, notifications to the mobile devices that the in-vehicle base station will be powering down.

3. The method of claim 2, wherein the notifications are short message service (SMS) messages.

4. The method of claim 2, further comprising requesting, from the network server, mobile device detach procedures for the mobile devices.

5. The method of claim 2, further comprising performing power control for neighboring nodes.

6. The method of claim 2, wherein the vehicle controller network is a controller area network (CAN) bus.

7. The method of claim 2, wherein the request includes a projected time that the in-vehicle base station will be powered down.
