Abstract: A vehicle telematics unit or other electronic hardware in a vehicle authenticates an incoming SMS message and provides additional security features above and beyond those inherent to the SMS protocol. A call center uses a mathematical function to derive a security code, and then sends an SMS message to the vehicle. The telematics unit can utilize the transmitted information to authenticate the sender of the SMS message and/or its contents. One group of suitable mathematical functions utilizes keyed-hash message authentication codes (HMACs).

Abstract: 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.

Abstract: The present invention detects whether an initial mobile number assignment is suboptimal, resulting in excessive roaming.

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 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.

Abstract: 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.

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 system for selectively providing an updated PRL to a remote wireless device reduces airtime requirements by determining the PRL to be loaded based on a collection of information relating to the wireless device. Depending upon the nature, connectivity and location of the device, the system loads a partial or full PRL, and may in certain circumstances decline to load any PRL, instead flagging the existing PRL as out-of-date.
