A vehicle backend system and a method of using the backend system to determine availability of a cellular connection between the backend system and a vehicle prior to the backend system attempting to establish the cellular connection. The method includes: determining at the backend system that a vehicle service is to be provided to the vehicle; based on the determination, transmitting from the backend system to a wireless service provider (WSP) or a WSP server a query associated with the connection status of the vehicle; in response to transmitting the query, receiving at the backend system a response to the query, wherein the response indicates that the vehicle is either in a connected state or an un-connected state; and when the vehicle is in the connected state: attempting to establish the cellular connection between the backend system and the vehicle; and when the cellular connection is established, providing the vehicle service.

Determining availability of a cellular connection between a vehicle and a vehicle backend system

A system and method of provisioning a wireless device that uses cellular communication protocols. The method carried out by the system includes: establishing a wireless communications session with the wireless device at a remote facility; transmitting provisioning information from the remote facility to the wireless device via the wireless communications session; and including a computer readable instruction with the provisioning information commanding the wireless device to contact the remote facility when the wireless communications session has been interrupted and the transmission of provisioning information is not complete.

Managing remote provisioning at a wireless device

A method of processing requests to establish wireless communication sessions in a mobile vehicle communications system. The method comprises receiving a request to establish a communication session between a telematics unit of a vehicle and a remote facility, wherein the request takes the form of one or more electrical signals. The method further comprises determining whether less than a predetermined number of requests to establish a communication session between the telematics unit and remote facility have been received from the sender of the request within a predetermined period of time. When it is determined that less than the predetermined number of requests have been received from the sender within the predetermined period of time, the method still further comprises establishing a communication session between the telematics unit and the remote facility. A system for performing or utilizing the above-described methodology is also provided.

Processing requests to establish communication sessions in a mobile vehicle communication system

A method of identifying abnormal activity within a communication system between one or more vehicles and a wireless carrier system. The method may include receiving a first record from a wireless carrier system or a call center. It may further include automatically receiving a second record from a data logger via a vehicle telematics unit. The second record may be a data upload record and includes information pertaining to a wireless connection that includes an event type (mode) and a call type (mode). The event type may indicate whether the wireless connection was SMS, circuit switched, or packet switched. The call type may indicate a transaction during the wireless connection. The method may include determining the occurrence of an abnormal activity based on the first record and the second record. And the method may also include providing a report.

Automated vehicle intrusion device

A method of wirelessly communicating packetized data between a vehicle and a central facility includes receiving a request at a vehicle telematics unit to transmit packetized data; determining whether the vehicle telematics unit is communicating through a roaming wireless carrier system; and delaying the transmission of packetized data between the vehicle telematics unit and a central facility until the vehicle telematics unit is no longer communicating through the roaming wireless carrier system.

Method of wirelessly communicating data between vehicles and central facilities

A method for associating routing event records with network records in a system including a GPS device, the method including: receiving, from the GPS device, a route request; sending, to the GPS device, route information corresponding to a route calculated based on the route request; storing, in a database, a routing event record corresponding to the sending of the route information; comparing a parameter of the routing event record with a corresponding parameter of a network record generated by a wireless carrier to determine whether the network record matches up with the routing event record; and associating the routing event record with the matched network record.
