  • Patent number: 9392452
    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.

  • Patent number: 9107195
    Abstract: A method of communicating with a telematics-equipped vehicle includes receiving a circuit-switched telephone call at a central facility from a telematics-equipped vehicle via a wireless carrier system that is in local communication with the telematics-equipped vehicle; determining during the circuit-switched telephone call that a separate packet-data communication session between the telematics-equipped vehicle and the central facility is desired; identifying the wireless carrier system that is in local communication with the telematics-equipped vehicle; querying the identified wireless carrier system from the central facility to determine whether the telematics-equipped vehicle is authorized to establish a packet-data communication session using the identified wireless carrier system; if so, obtaining an Internet protocol (IP) address from the identified wireless carrier system; and commencing the exchange of data between the telematics-equipped vehicle and the central facility using the obtained IP address.

  • Patent number: 8908561
    Abstract: A system and method for executing network acquisition employ a triggered scan for network acquisition regardless of the recorded optimal nature of the current network. In general, when one or more predefined conditions occur, a network scan is initiated to identify another network, if any, that is more optimal than the current network. Example trigger conditions include failed registration attempts, exceeding a predetermined distance threshold, entry to or exit from a pre-determined region, excess CDMA Chip delay, and others. Triggers may be used singly or in Boolean combinations. In this way, network scanning occurs when it may be beneficial, but will not be initiated too frequently or in situations where connectivity may not actually be suboptimal. This triggered scan provides improved connectivity, and can allow the device to make and receive calls in locations where it would otherwise not have been possible.

  • Publication number: 20140339598
    Abstract: The present invention relates to a nitride-semiconductor light-emitting element in which a p-type nitride layer is doped with carbon, and to a production method therefor. More specifically, the present invention relates to a nitride-semiconductor light-emitting element comprising a p-type nitride layer formed from a nitride having a high concentration of free holes as the carbon is auto-doped in accordance with adjustment of the rate of flow of a nitrogen source. The nitride-semiconductor light-emitting element of the present invention can provide a high free-hole concentration, which is difficult to achieve with conventional single p-type dopants, and can therefore lower the resistance and increase the light efficiency of the light-emitting element.

  • Patent number: 8892051
    Abstract: The disclosed invention provides a system and method for efficiently establishing a data call connection from a TSP call center to deactivated telematics units without a subscriber profile being in an HLR or VLR and without the use of a “500” number. An equipment identifier associated with a deactivated telematics unit may be delivered to the wireless network provider, and a calling line ID based on the equipment identifier and a common number for deactivated telematics units may be translated into a paging address through which the deactivated telematics unit may be paged. An appropriate paging strategy based on the network topology may be used to page the deactivated telematics unit and establish a data call connection with the deactivated telematics unit. The deactivated telematics unit may then be provisioned or perform or have performed on it other functions based on the data call connection.
