  • Patent number: 8712379
    Abstract: A system and method for transmitting short message service (SMS) messages between a vehicle and a central facility includes determining an authentication tone having a unique characteristic, generating an SMS message that includes computer-readable data representing the authentication tone; sending the SMS message to a central facility, establishing a call between the central facility and the vehicle using a vehicle telematics unit and a wireless carrier system, generating the determined authentication tone at the vehicle, and transmitting the generated authentication tone over the established call to the central facility.

  • Patent number: 8682364
    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.

  • Patent number: 8676199
    Abstract: A system and method for making vehicle originated calls to a telematics service provider or other call center. The method includes identifying a call type associated with a desired wireless communication of speech or data to the call center, and then carrying out one of a number of different call connection processes depending on the call type. For voice channel cellular connections, an in-band modem cellular connection is preferably established in most instances using a connection retry strategy that includes primary, secondary, and possibly tertiary connection attempts. The system and method can be carried out in connection with various cellular system technologies, but is especially suited for use with GSM systems.

  • Patent number: 8675629
    Abstract: A system and method of extending the range of a vehicle telematics unit includes determining that a vehicle telematics unit is outside of a geographic range beyond which time division multiple access (TDMA) transmissions sent from the vehicle telematics unit to a base station arrive at the base station after a time slot allocated to the vehicle telematics unit in a time frame has passed; calculating a time delay that causes the TDMA transmissions to arrive at the base station in the allocated time slot of a subsequent time frame; and sending TDMA transmissions from the vehicle telematics unit at a time determined using the time delay.

  • Patent number: 8582499
    Abstract: A timing control method for use with wireless communications involving telematics-equipped vehicles. The timing control method generally determines a temporally-distributed sequence of message response times for a group of telematics-equipped vehicles, and then includes these different response times in wireless messages that are sent to the vehicles. In reply, the vehicles use the various message response times to respond in an apportioned or distributed fashion that generally correlates with the temporally-distributed sequence; instead of all at once. In another disclosed method, the response times are determined at each vehicle itself. The methods can be used for requesting data from vehicles via SMS messages.

  • Patent number: 8583199
    Abstract: Vehicle telematics systems and methods for vehicle telematics systems are provided. The telematics system includes a first antenna, a second antenna, and a processing device. The first antenna is disposed at a first location on the vehicle. The second antenna is disposed at a second location on the vehicle. The second location is remote from the first location. The processing device is coupled to the first antenna and the second antenna. The processing device is configured to monitor a parameter that is indicative as to whether the first antenna is operational, communicate using the first antenna if the parameter indicates that the first antenna is operational, and communicate using the second antenna if the parameter indicates that the first antenna is not operational.

  • Patent number: 8565837
    Abstract: The described invention provides a method and system for allowing subscribers of a telematics service provider (TSP) to make hands-free phone calls within their vehicles through a telematics unit over a network or hardware-based pre-pay system, wherein the telematics unit or a wireless network provider associated with the TSP controls the ingoing and outgoing hands-free calling (HFC) processes. The wireless network provider, through its system at a remote call center or through the telematics unit, may determine whether the subscriber has subscribed to the TSP's HFC service, whether the subscriber has a sufficient remaining balance to initiate, receive or continue a call, and whether a user of the telematics unit is “roaming.” When a user attempts to make or receive a call through the telematics unit, the wireless network provider or the telematics unit may handle the incoming or outgoing call processing, and may further provide subscriber account balance notifications to the user.

  • Patent number: 8559910
    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.

  • Patent number: 8548508
    Abstract: A method of identifying telematics calls includes the steps of receiving at a vehicle telematics unit a paging message used to connect a call over a wireless carrier system; determining at the vehicle telematics unit if the paging message used to connect the call includes a Mobile Identification Number (MIN) or a Mobile Equipment Identifier (MEID); and establishing the call and, if the vehicle telematics unit determines that the paging message includes the MEID, entering into a mode in which the vehicle telematics unit uses a modem for receipt and transmission of data.

  • Patent number: 8483245
    Abstract: A method and system for modem signaling over a voice channel of a cellular or other wireless communication system. A plurality of sequential tones are transmitted, each of which corresponds to at least one network type and contains at least one primary frequency selected so as to successfully be passed through its associated network type. This permits the use of modem signaling to establish a data connection regardless of the type of network equipment utilized, so that the method will work with both newer and older generation vocoders and other network equipment.
