摘要:
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 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 technique and system are provided for executing a delayed geographically specific activation procedure for a telematics unit associated with a vehicle. In an exemplary mode, the method includes first programming a memory of the telematics unit with geographically specific data including at least a location identifier specifying a geographic location and a PRL associated with the specified geographic location. After the vehicle is transported into the geographic location specified by the location identifier, the telematics unit detects that the vehicle is in the specified geographic location and responsively activates a PRL associated with the specified geographic location. Having access to the PRL, the telematics unit initiates a number assignment process over a wireless network extending within the specified geographic location via OTASP or a cleared number call, so that the telematics unit is assigned a dialing number associated with the specified geographic location.

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.

A method of operating a vehicle telematics unit includes determining the location of a vehicle equipped with a vehicle telematics unit; determining if telematics dialing software operated by the vehicle telematics unit includes a verbal dialing protocol used at the determined vehicle location; if not, identifying one or more verbal dialing protocols used at the determined location of the vehicle; requesting telematics dialing software that includes the one or more identified verbal dialing protocols; receiving the requested telematics dialing software from a central facility; and storing the received telematics dialing software at the vehicle.

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 method for reactivating a then-currently deactivated mobile unit involves submitting a request to a call center to reactivate the mobile unit and, upon receiving the request, submitting another request to a cellular service provider from the call center, where such other request includes a request to broadcast a message having a mobile unit identifier and a reactivation protocol contained therein. The method further involves broadcasting the message from the cellular service provider to a plurality of mobile units each having an identical inactive dialing number stored therein. A processor operatively associated with the then-currently deactivated mobile unit recognizes the mobile unit identifier contained in the broadcasted message. Upon recognizing the mobile unit identifier, the processor applies the reactivation protocol contained in the broadcasted message to initiate reactivation of the then-currently deactivated mobile unit.
摘要:
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.
