OTA initiation method for telematics system in 2G GSM/3G WCDMA network
First Claim
1. A method for processing a location update from a telematics unit, the method comprising:
- receiving, at a mobile switching center (MSC), a location update from a telematics unit of a telematics-equipped vehicle over a network;
determining, at the MSC, that cellular service information corresponding to the telematics unit has not yet been programmed into an Home Location Register (HLR) on the network, and, in response, holding the location update; and
determining that the cellular service information corresponding to the telematics unit is programmed into an HLR on the network, and, in response, initiating an over-the-air (OTA) configuration session with the telematics unit so as to configure the telematics unit for cellular services.

Abstract
The described method and system provide for over-the-air configuration of a telematics-equipped vehicle by wireless carriers and telematics service providers (TSPs). Regardless of whether a telematics-equipped vehicle has been provisioned for cellular service or not, the TSP and wireless carrier may control undesirable location updating from the vehicle, for example, by setting certain triggers or conditions upon the telematics unit before processing location updates provided by the telematics unit. These triggers or conditions may also be programmed into the telematics unit, whether through an OTA configuration session, or pre-loaded during manufacture. The TSP or wireless carrier may conduct OTA configuration sessions with the telematics unit to provision the telematics unit for cellular service, or provide the telematics unit with software or firmware updates.

7. A method for processing location updates by a telematics unit, the method comprising:
-
sending, to the telematics unit from a call center, an instruction not to send location updates until cellular service information corresponding to the telematics unit is programmed into an Home Location Register (HLR) on the network; and determining, by the call center, that the cellular service information corresponding to the telematics unit is programmed into an HLR on the network, and, in response, initiating, at the call center, an over-the-air (OTA) configuration session with the telematics unit and notifying the telematics unit that cellular service information corresponding to the telematics unit was programmed into an HLR on the network. - View Dependent Claims (8, 9, 10, 11)

12. A tangible, non-transient computer-readable medium, part of a telematics unit on a telematics-equipped vehicle, having thereon computer executable instructions for sending location updates over a network, the computer executable instructions comprising instructions for:
-
sending a location update over a network based on whether cellular service information corresponding to the telematics unit has been programmed into an Home Location Register (HLR) on the network; and determining that the cellular service information corresponding to the telematics unit is programmed into an HLR on the network, and, in response, connecting to at least one of a call center and a wireless carrier over the network to conduct an over-the-air (OTA) configuration session. - View Dependent Claims (13, 14, 15)
