Abstract: The described method and system provide a connectivity problem resolution mechanism that uses a data mode call in order to diagnose a connection problem while avoiding audible ringing and or inadvertent user pick-up during error diagnosis and correction. The system includes three primary functions and elements including cellular error message recognition, error response handling configured to update and/or maintain processes, and new error message capture. This system is usable both online and offline. Error recognition may be based on error message matching or keyword matching.

Abstract: A method for notifying parties in close proximity to a vehicle of a potential vehicle hazard includes detecting that the vehicle has been in a collision, determining the type of propulsion system used by the vehicle, generating a warning or other notification relating to the propulsion system, and communicating the notification to a party located within a predetermined range of the vehicle. Communication of the notification can be carried out by renaming the telematics unit with a device name corresponding to a hazard associated with the propulsion system, and then broadcasting the device name according to an established wireless protocol.

Abstract: A method of establishing an alternate communication channel between a telematics unit and a central facility that includes determining that a vehicle telematics unit is unable to communicate data over a voice call using a voice channel; initiating a data call from the vehicle telematics unit to a central facility based on that determination; sending information identifying the vehicle telematics unit to the central facility over the data call; establishing a voice call from the central facility to verbally communicate with the vehicle telematics unit based on the information identifying the vehicle telematics unit; and communicating data between the central facility and vehicle telematics unit via short messaging services (SMS) messages using the voice call from the central facility.

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.

Abstract: 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.

The charge reminder my be visible and/or audible within the vehicle and may optionally be remote from the vehicle.

Abstract: A system and method for monitoring wireless network performance that provides a real-time detection and identification of problem areas within a wireless carrier's network. The method involves receiving and attempting to fulfill requests for vehicle services data sent via the wireless carrier system between vehicles and a call center or other remote facility. The success or failure of these attempts are recorded and associated with the geographic region in which the vehicle was located during the attempt, and this information for a multitude of vehicles is then analyzed in conjunction with other inputs and stored data to determine whether a particular geographic region is experiencing a wireless service outage or other degradation in performance.

Abstract: A system and a method for improving wireless communications between a call center and a vehicle. The system and method can reduce the number of wireless connections needed between a call center and a vehicle by using multimedia messaging service (MMS) messages to convey information therebetween. This obviates the need for the call center to make an initial wireless connection simply to alert the vehicle that it wishes to communicate. Instead, the system and method can convey information or push down content to the vehicle on a very first connection, which can reduce wireless connections and improve reliability.

Abstract: A telematics unit is provided for a vehicle having a power unit, along with a method for controlling a telematics unit for a vehicle. The telematics unit includes a voltage sensor, a global positioning system unit, and a processor. The voltage sensor senses a measure of a voltage of the power unit. The global positioning system unit obtains position data as to a position of the vehicle. The processor is coupled to the voltage sensor and the global positioning system unit. The processor is configured to determine whether the voltage for the power unit has decreased using the sensed measure of the voltage, determine whether the vehicle is moving using the position data, and command the telematics unit to an off mode if the voltage has decreased and the vehicle is not moving.

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.

At least some of the stored data is transmitted from the telematics unit to a server in selective communication with the telematics unit.

Abstract: 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.
