摘要:
A method and system for local broadcasting of messages from a wireless mobile device to many others located within the same geographic area. This can be done using SMS messaging wherein a message to be broadcast is addressed to a particular designated address and, when received by a wireless carrier system, is checked to determine that it came from an authorized sender, and then is broadcasted by the wireless carrier system to a geographically-limited area within which the sending wireless mobile device is located.

Vehicle telematics systems and methods for vehicle telematics systems are provided. The telematics system includes a first antenna, a second antenna, and a processing device. The first antenna is disposed at a first location on the vehicle. The second antenna is disposed at a second location on the vehicle. The second location is remote from the first location. The processing device is coupled to the first antenna and the second antenna. The processing device is configured to monitor a parameter that is indicative as to whether the first antenna is operational, communicate using the first antenna if the parameter indicates that the first antenna is operational, and communicate using the second antenna if the parameter indicates that the first antenna is not operational.

A method of carrying out communications using a vehicle telematics unit includes identifying a cellular base station in wireless communication with a vehicle telematics unit; attempting an emergency call via the identified cellular base station using the vehicle telematics unit; determining that a forward link portion of a cellular signal between the vehicle telematics unit and the identified cellular base station lacks sufficient strength to place the attempted emergency call; and transmitting emergency communications via the identified cellular base station using a reverse link portion of the cellular signal based on the determination.
摘要:
A system and method for extending the cellular range of communications using a vehicle telematics unit. The system includes the vehicle telematics unit which is connected with other vehicle hardware and includes wireless cellular capability for communicating from the vehicle to a call center or other facilities via a wireless communication system. The method carried out by the system includes identifying a cellular base station in wireless communication with a vehicle telematics unit; attempting an emergency call via the identified cellular base station using the vehicle telematics unit; determining that a forward link portion of a cellular signal between the vehicle telematics unit and the identified cellular base station lacks sufficient strength to place the attempted emergency call; and transmitting emergency communications via the identified cellular base station using a reverse link portion of the cellular signal based on the determination.

A method for updating an electronic calendar in a vehicle involves uploading an appointment to the electronic calendar, where the appointment includes a description of an event, a time block for the event, and a travel time preceding the time block. An alert is set in a telematics unit of the vehicle, where the alert notifies a vehicle occupant of the appointment. The alert is configured to be activated in response to a trigger. At a time subsequent to the time block of the event, one of i) a memo is uploaded to the electronic calendar indicating that the alert was activated, or ii) another memo is uploaded to the electronic calendar indicating that the alert was not activated.
摘要:
A system and method for monitoring vehicle position includes receiving vehicle location information at a mobile wireless device via short-range communication from the vehicle, storing the received vehicle location information at the wireless mobile device, receiving a request from a user of the wireless mobile device for a navigational route to the vehicle, determining the location of the wireless mobile device, and providing at the wireless mobile device the navigational route between the wireless mobile device and the vehicle based on the wireless mobile device location and vehicle location. This can be helpful where a user has parked his or her car and thereafter needs assistance locating where it is parked.

摘要:
The described method and system provide for synchronizing a mobile application on a mobile device with a DRx (discontinuous receive) schedule of a vehicle. When the vehicle ignition is turned off, a telecommunications unit on the vehicle sends a synchronization message to the mobile device, which allows the mobile application to synchronize with the DRx schedule of the vehicle. The DRx schedule includes a standby mode, a cyclic mode, and a powered down mode for the vehicle, and user requests inputted into the mobile application will be processed according to the mobile application's determination of vehicle availability during those modes. The mobile application is thus able to inform the user of the vehicle status at any point during the vehicle's DRx schedule without requiring any further information from the vehicle after the synchronization message.
