Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A timing control method for use with wireless communications involving telematics-equipped vehicles. The timing control method generally determines a temporally-distributed sequence of message response times for a group of telematics-equipped vehicles, and then includes these different response times in wireless messages that are sent to the vehicles. In reply, the vehicles use the various message response times to respond in an apportioned or distributed fashion that generally correlates with the temporally-distributed sequence; instead of all at once. In another disclosed method, the response times are determined at each vehicle itself. The methods can be used for requesting data from vehicles via SMS messages.

Abstract: A method for operating three-way calling for a telematics unit including establishing a first connection between a call center and the telematics unit based on a trouble call request, sending call instructions from the call center to the telematics unit via the first connection based on the trouble call request and establishing a second connection from the telematics unit to one of the call center or a contact-problem number associated with the trouble call request based on the call instructions.

Abstract: A method and system for configuring a telematics device is constructed so as to use two-way short message service (SMS) to provide improved configuration execution. Mobile identification number (MIN), Mobile Directory Number (MDH), Home System Identification (SID) number, SID/NID pairs, NAI/password for packet data, over the air service provisioning (OTASP) number, and Preferred Roaming List (PRL) flag can be easily updated with no manual or voice channel configuration actions. In addition, other system settings such as button behavior, language, call barring, adding units to hands-free calling, etc. may be updated as well. In an example, a series of binary SMS messages configures the telematics device, with a subset of the messages being used specifically for configuration while the remaining message initiates a packet data session to complete additional configuration.

Abstract: 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.

Abstract: An authentication method that can be used by a telematics-equipped vehicle to authenticate an SMS message and provide additional security features above and beyond those inherent to the SMS protocol. Generally speaking, a call center uses a mathematical function to derive a security code, and then sends an SMS message to a telematics-equipped vehicle that includes information related to the derived security code. The telematics-equipped vehicle 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 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.

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.

Abstract: The present invention provides a system and method for audible caller identification with nametag storage. A call signal is received, the call signal including an automatic number identification. A determination is made whether the automatic number identification matches a nametag-identified number on a nametag list stored in a telematics unit. An audible user action identification message is sent based on the determination. Monitoring for a user voice response to the audible user action identification message is performed. A determination is made whether to connect the call signal based on a received user voice response. The call signal is sent to a voice mail system or sent to a phone based on the received user voice response. An audible nametag storage message is sent. A computer usable medium with suitable computer program code is employed for audible caller identification with nametag storage.

Abstract: The present invention provides a method for implementing automated call routing using an origin identifier within a telematics equipped mobile vehicle that includes receiving an incoming call signal, the incoming call signal including an origin identifier, determining an answer mode based on the origin identifier of the incoming call signal, initiating the answer mode responsive to the answer mode determination, and operating the telematics unit based on the initiated answer mode. Origin identifiers may include an automatic number identifier and a digital signature. The step of determining the answer mode may include determining a first answer mode when the origin identifier is within a predetermined group of origin identifiers and determining a second answer mode when the origin identifier is not within the predetermined group of origin identifiers.
