Out-of-band power down notification
First Claim
1. A mobile base station for reducing coverage interruptions for users connected thereto, comprising:
- a vehicle bus notification module coupled to a vehicle electrical power system and configured to determine a vehicle battery power level, the vehicle electrical power system powering the mobile base station;
a first radio access network interface for communicating with mobile devices using a first radio access technology;
a backhaul interface for communicating with an operator core network;
a processor, in communication with the vehicle bus notification module, the first radio access network interface, and the backhaul interface; and
a memory, 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;
requesting, in response to receiving the vehicle bus low power alert, from a network server, a mobile device detach procedure for the mobile devices;
sending, in response to receiving the vehicle bus low power alert, to the network server, a message to cause the network server to perform power control of a neighboring base station to increase or decrease transmission power; and
sending a message via the backhaul interface to the operator core network to request a notification to be sent to the mobile devices, the notification configured to include human-readable information regarding the vehicle battery power level of the mobile base station,thereby enabling the mobile devices to be notified via the operator core network when the vehicle battery power level is low.

5. A method, comprising:
-
receiving, at an in-vehicle base station, a low power alert from a vehicle controller network regarding a vehicle battery power level of the in-vehicle base station; 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; requesting, in response to receiving the low power alert, from the network server, a mobile device detach procedure for the mobile devices; sending, in response to receiving the low power alert, to the network server, a message to cause the network server to perform power control of a neighboring base station to increase or decrease transmission power; and sending, from the network server, notifications to the mobile devices, the notifications configured to include human-readable information regarding the vehicle battery power level of the in-vehicle base station, thereby enabling the mobile devices to be notified via the network server when the vehicle battery power level is low. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
