20090012675 | METHOD OF PROVIDING DATA-RELATED SERVICES TO A TELEMATICS-EQUIPPED VEHICLE - A communications method that gathers status information on a telematics-equipped vehicle before establishing a mobile-terminated data connection with that vehicle. In general, the communications method sends a status request message to a wireless carrier system that asks for certain status information on a particular telematics-equipped vehicle. After the wireless carrier system gathers the status information, it sends back a status response message. If the status response message indicates that the telematics-equipped vehicle is able to receive certain data-related services, then a mobile-terminated data connection is established and the services are provided. If the telematics-equipped vehicle is unable to receive the data-related services, then attempts are made to identify and resolve the problem. In cases where the telematics-equipped vehicle is not registered with a wireless network, a monitor request message is sent to the wireless carrier system which puts it on the lookout for registration of the vehicle in question. | 01-08-2009 |
20090047929 | METHOD OF AUTHENTICATING A SHORT MESSAGE SERVICE (SMS) MESSAGE - An authentication method that can be used by a telematics-equipped vehicle to authenticate an SMS message and provide additional security features above and beyond those inherent to the SMS protocol. Generally speaking, a call center uses a mathematical function to derive a security code, and then sends an SMS message to a telematics-equipped vehicle that includes information related to the derived security code. The telematics-equipped vehicle can utilize the transmitted information to authenticate the sender of the SMS message and/or its contents. One group of suitable mathematical functions utilizes keyed-hash message authentication codes (HMACs). | 02-19-2009 |
20090088153 | Determining Mobile Phone Number Assignment - The present invention detects whether an initial mobile number assignment is suboptimal, resulting in excessive roaming. If excessive roaming is encountered, the telematics service provider determines the effective home area of the telematics unit and assigns an appropriate replacement number to the unit. In this way, the disclosed principles allow a telematics service provider to decrease its roaming charges, and/or those of its users, and more optimally manage its mobile phone number assignments. | 04-02-2009 |
20090088187 | Method and System for Configuring a Telematics Device Using Two-Way Data Messaging - A method and system for configuring a telematics device is constructed so as to use two-way short message service (SMS) to provide improved configuration execution. Mobile identification number (MIN), Mobile Directory Number (MDH), Home System Identification (SID) number, SID/NID pairs, NAI/password for packet data, over the air service provisioning (OTASP) number, and Preferred Roaming List (PRL) flag can be easily updated with no manual or voice channel configuration actions. In addition, other system settings such as button behavior, language, call barring, adding units to hands-free calling, etc. may be updated as well. In an example, a series of binary SMS messages configures the telematics device, with a subset of the messages being used specifically for configuration while the remaining message initiates a packet data session to complete additional configuration. | 04-02-2009 |
20090168742 | METHOD FOR CONTROLLING THE TIMING OF WIRELESS COMMUNICATIONS INVOLVING TELEMATICS-EQUIPPED VEHICLES - 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. | 07-02-2009 |
20090247132 | SYSTEM AND METHOD FOR PROCESSING VEHICLE COMMUNICATIONS - A system and a method for improving wireless communications between a call center and a vehicle.

20110069680 | ENHANCED MOBILE NETWORK SYSTEM ACQUISITION USING SCANNING TRIGGERS - 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. | 03-24-2011 |
