20140192711 | SYSTEM AND METHOD FOR SERVING BINARY SHORT MESSAGE SERVICE CONTENT TO DIFFERENT WIRELESS NETWORKS - Systems and methods are described for serving binary short message service (SMS) content to multiple mobile devices that use different wireless networks to receive data. One implementation involves a method for serving binary SMS content to the subscribers of a telematics service provider (TSP) on multiple mobile devices that are provisioned with multiple wireless networks. The method involves receiving a binary SMS at a receiving module of an external short message entity (ESME), translating the SMS into a protocol data unit (PDU), and routing the PDU to an SMS gateway producing application. The PDU is directed to a virtual serial port, which is created by the gateway producing application and mapped to a physical serial port at a terminal server. The PDU is sent from the terminal server to a data modem that is provisioned with a wireless carrier, and the data modem is instructed to transmit the SMS to a mobile device. | 07-10-2014 |
20140199989 | VEHICLE TELEMATICS UNIT MANAGEMENT - A method and system for maintaining a wireless carrier system presence at a vehicle telematics unit in a vehicle includes placing the vehicle telematics unit in a quiescent mode that suspends its signal transmitting functions; instructing the vehicle telematics unit to periodically exit the quiescent mode and transmit a query that determines if the wireless carrier system used by a telematics service provider has changed; when the wireless carrier system has changed, receiving a new wireless profile associated with a new wireless carrier system; and storing the new wireless profile in a universal integrated circuit card (UICC) hardwired at the vehicle. | 07-17-2014 |
20140248860 | Provisioning Automotive SIM Cards without Removal from Vehicle - A system and method are provided for re-provisioning a telematics unit of a telematics-equipped vehicle for wireless services. The re-provisioning process includes: connecting a computing device to an on-board diagnostics interface of the telematics-equipped vehicle; accessing a subscriber identification card of the telematics unit via the on-board diagnostics interface; requesting subscription information from a subscriber credentials server via a network connection; receiving the subscription information; and reprogramming the subscriber identification card of the telematics unit for wireless services based on the received subscription information. | 09-04-2014 |
20150072668 | MANAGING WIRELESS VOICE AND DATA COMMUNICATIONS - A method of controlling wireless voice and data communications includes identifying a radio access technology (RAT) in use at a vehicle telematics unit; establishing a wireless connection between the vehicle telematics unit and a central facility; wirelessly transmitting the identity of the RAT from the vehicle telematics unit to the central facility; receiving a message at the vehicle telematics unit from the central facility based on the identity of the RAT causing the vehicle telematics unit to: carry out simultaneous voice and data communications over a single wireless connection with the central facility when the identified RAT supports simultaneous voice and data communications; and establish a voice call with the central facility and receive data via short message service (SMS) messages when the identified RAT does not support simultaneous voice and data communications. | 03-12-2015 |
20150215986 | VEHICLE TELEMATICS CONNECTION RETRY - A method of re-establishing a cellular connection between a vehicle telematics unit and a wireless carrier system includes detecting a loss of cellular connection between a vehicle telematics unit and a wireless carrier system; accessing a technology order table (TOT) that orders a plurality of radio access technologies (RATs) capable of use at the vehicle telematics unit according to desirability; attempting to re-establish the cellular connection by: determining the RAT used by the vehicle telematics unit when the loss of cellular connection was detected; searching the TOT to locate a less desirable RAT relative to the RAT used by the vehicle telematics unit when the loss of cellular connection was detected; attempting to connect with the wireless carrier system using the less desirable RAT and a group of PLMNs that is limited to home and home-equivalent PLMNs; and if that attempt fails, attempting to connect with the wireless carrier system by iterating through each of the RATs ordered in the TOT beginning with a next less desirable RAT and including in the iteration the RAT used by the vehicle telematics unit when the loss of cellular connection was detected, wherein step (c4) uses all non-forbidden PLMNs. | 07-30-2015 |
20150222553 | PROVIDING CELLULAR DATA TO A VEHICLE OVER DIFFERENT DATA CHANNELS - A method and a system for providing vehicle data services to communication devices located at a remote vehicle. The method includes the steps of: establishing data communication between a telematics backend system and one of a plurality of communication devices located at the remote vehicle; determining at the telematics backend system an access point name (APN) for at least one of the plurality of communication devices, a type of vehicle services data for the at least one of the plurality of communication devices, or both; and based on the determined APN, the type of vehicle services data, or both, transmitting from or receiving at the telematics backend the vehicle services data according to a network traffic shaping scheme. | 08-06-2015 |
20150223273 | PROVIDING CELLULAR DATA TO A VEHICLE OVER DIFFERENT DATA CHANNELS - A method and a system for providing vehicle services to at least one communication device located at a vehicle via a vehicle telematics unit. The method carried out by the system includes the steps of: receiving a request at the vehicle telematics unit for first vehicle services from a first communication device located at a vehicle; associating a first identifier with the first communication device; and providing the first vehicle services to the first communication device, wherein the vehicle services are provided according to at least one services parameter associated with the first identifier. | 08-06-2015 |
20160135039 | REMOTE TELEMATICS UNIT BAND CONTROL WITH DYNAMIC MEMORY - A system and method of remotely changing use of a cellular protocol at a vehicle includes: storing, in a network access device (NAD) at the vehicle, identities of one or more cellular bands that provide cellular service according to an up-to-date cellular protocol; wirelessly receiving at the vehicle a computer-readable instruction that deactivates the up-to-date cellular protocol; and in response to the computer-readable instruction, the vehicle: obtains the identities of the cellular bands stored in the NAD; stores the obtained identities in a non-volatile memory device located apart from the NAD; and erases in the NAD the identities of the cellular bands that provide cellular service according to an up-to-date cellular protocol. | 05-12-2016 |
