Patent number: 9392452Abstract: 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.Type: GrantFiled: December 26, 2007Date of Patent: July 12, 2016Assignee: General Motors LLCInventors: Elizabeth Chesnutt, Sethu K. Madhavan, Ki Hak Yi

Patent number: 8908561Abstract: 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.Type: GrantFiled: September 18, 2009Date of Patent: December 9, 2014Assignee: General Motors LLCInventors: Kevin R. Krause, Ayaz S. Kassam, James Doherty, Ki Hak Yi

Patent number: 8892051Abstract: 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.Type: GrantFiled: March 25, 2011Date of Patent: November 18, 2014Assignee: General Motors LLCInventors: Ki Hak Yi, Sethu K.

Patent number: 8879451Abstract: The described method and system provide for processing telematics service-related calls on a telematics-equipped vehicle when the vehicle ignition is off. By utilizing one or more call timers, the described invention is able to prevent excessive drain to the vehicle battery while still providing broad access to telematics services when the vehicle ignition is off. Certain types of calls may be excepted from the call timers, and different types of calls may use different call timers. A call center may also intervene and modify the process by changing the values of the timers.Type: GrantFiled: July 15, 2011Date of Patent: November 4, 2014Assignee: General Motors LLCInventors: Ki Hak Yi, Christopher N. Shamoun

Patent number: 8798623Abstract: 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. Cell selection can be carried out using an acquisition task, background scan and inter-country PLMN reselection process that are used to select among available PLMNs and base stations. The system and method can be carried out in connection with various cellular system technologies, but is especially suited for use with GSM systems.Type: GrantFiled: August 14, 2009Date of Patent: August 5, 2014Assignee: General Motors LLCInventors: Ki Hak Yi, Sethu K.
