A method for managing data transmissions in a subscriber pool involves receiving a telematics unit call at a call center on a channel other than a packet data channel, and from the call and at the call center, recognizing that the packet data channel is unavailable in a predetermined coverage region. A notification is transmitted to the telematics unit and/or to a plurality of telematics units in the predetermined coverage region indicating that the packet data channel is unavailable for a predetermined time. In response to the notification, a vehicle data upload setting is reset in the telematics unit and/or each of the plurality of telematics units to an alternate channel such that primary connection attempts made by the telematics unit and/or each of the plurality of telematics units are via the alternate channel during the predetermined time. A system for managing such data transmissions is also disclosed.

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.

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.

A system and method for monitoring and reporting telematics unit communication network system acquisition and scanning performance is disclosed herein. An example of the method includes monitoring a scan of all cellular networks that are available to a vehicle telematics unit, and during the monitoring, recognizing a predetermined trigger. In response to the predetermined trigger, a memory buffer in the telematics unit stores data associated with at least one of performance or outcome of the scan. At least some of the stored data is transmitted from the telematics unit to a server in selective communication with the telematics unit.
摘要:
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.
摘要:
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.

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.

A method of updating a roaming list in a mobile device is disclosed herein. The method involves detecting an occurrence of an event via a processor at a back-end system, generating a trigger in response to the detecting of the occurrence of the event, and recognizing, by the processor, the trigger as a roaming list update trigger. The method further includes identifying the mobile device, via the processor, as requiring a roaming list update based on the recognizing of the roaming list update trigger, and transmitting, via a wireless connection, the updated roaming list from the back-end system to the identified mobile device.
摘要:
A method for communicating with a vehicle about then-current vehicle operating conditions is disclosed herein. The method includes real-time monitoring, via a telematics unit in a vehicle, of vehicle data when the vehicle is traveling on a road segment, comparing the real-time monitored vehicle data with previously stored data of one or more other vehicles that previously traveled the road segment, and based on the comparison, determining an operation of the vehicle in order to achieve optimal fuel efficiency. The method further includes submitting, to the vehicle, the operation of the vehicle for i) increasing a then-current fuel efficiency of the vehicle or ii) maintaining the then-current fuel efficiency of the vehicle. Also disclosed herein is a system for accomplishing the same.

The disclosed invention provides a system and apparatus for providing a telematics system user with an improved texting experience. A messaging experience engine database enables voice avatar/personality selection, acronym conversion, shorthand conversion, and custom audio and video mapping. As an interpreter of the messaging content that is passed through the telematics system, the system eliminates the need for a user to manually manipulate a texting device, or to read such a device. The system recognizes functional content and executes actions based on the identified functional content.
