Abstract: A processing system and method for controlling the distribution of certain types of electronic messages, such as SMS messages, instant messages, emails, etc., that are wirelessly sent to a vehicle. In one embodiment, a messaging application installed on a communication device diverts to a call center outgoing messages destined for the vehicle. Once the electronic message is properly checked and authenticated at the call center, it is wirelessly forwarded on to the vehicle where its contents can be displayed to the passengers. By controlling the distribution of these types of electronic messages to the vehicle, the processing method can reduce or mitigate the effects of unauthorized third party communications.

Abstract: A tone detector and associated method for use with EVRC-B and GSM vocoders to enable reliable detection of system connect tones over a wireless communication system. The tone detection method examines a number of sequential data frames of the signal received from the vocoder and determines that the tone is present if the spectral energy at frequencies around the tone is much higher than that at neighboring frequencies and if the calculated center frequency of the data frames is at or near the frequency of the tone.

Abstract: A system and method for producing cryptographic keys for use by an embedded processing device within a manufactured product. A pseudo random number generator is seeded with entropy data gathered by the embedded device, and the result is used to generate a public-private key pair. The process can be carried out during manufacturing so that the public key of each manufactured product can be stored in a database along with a unique identifier for the embedded device associated with the key. In one particular example, a vehicle having an installed telematics unit uses the key generating process to self-generate keys using entropy data available to the vehicle.

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.

Abstract: A system and method for sending binary data via a short message service (SMS) over a wireless communication system. The method provides the capability to send and receive binary data to a vehicle telematics unit using a text SMS message. The binary data is converted to encoded text according to an encoding scheme supported by a wireless communication system. Then, the encoded text is sent as an SMS message over the wireless communication system. Once, the SMS message containing the encoded text is received at its destination, it is converted back to binary data.
