Enhanced Mobile Base Station
First Claim
1. A method, comprising:
- at a processor configured to provide a cellular base station functionality, the processor being part of a mobile base station, the processor coupled to a first access radio for providing a cellular access network inside and outside a vehicle, the processor further coupled to a first cellular backhaul radio for providing a backhaul connection to a cellular network via a cell, the processor further coupled to a global positioning system (GPS) module for determining a location of the mobile base station;
permitting a mobile device to attach to the mobile base station;
attaching, at the mobile base station, to a macro cell for providing backhaul to the mobile device using the mobile base station for access;
receiving a first tracking area code from the macro cell;
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 the 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 the coordinating node,thereby avoiding unnecessary tracking area updates for the mobile device.

Abstract
Systems and methods for an in-vehicle base station are described. In one embodiment, a method is disclosed, comprising: permitting a mobile device to attach to the mobile base station; attaching, at the mobile base station, to a macro cell for providing backhaul to the mobile device using the mobile base station for access; receiving a first tracking area code from the macro cell; 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 the 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 the coordinating node.

9. A non-transitory computer-readable medium storing one or more instructions that, when executed by one or more processors, cause the one or more processors to:
-
permit a mobile device to attach to the mobile base station; attach at the mobile base station, to a macro cell for providing backhaul to the mobile device using the mobile base station for access; receive a first tracking area code from the macro cell; transmit a second tracking area code to the mobile device, the second tracking area code corresponding to a tracking area managed by a coordinating node; detect at the mobile base station, a transition from a stationary state to a moving state of the mobile base station; and send a tracking area update message to a core network to transition to the tracking area managed by the coordinating node, thereby avoiding unnecessary tracking area updates for the mobile device.
