Abstract: Disclosed is a method of manufacturing a polyurethane filter foam having excellent air permeability, elasticity, and restoring force. In the method of manufacturing the polyurethane filter foam, the cell size of the filter foam is made regular by controlling the pressure by adjusting the diameter of the foaming head of a foaming machine, rather than adding a cell opener, cell irregularity caused by poor dispersion of the cell opener is alleviated, and air permeability, porosity, and compression set are excellent.

Abstract: A connected car service information protection method is used for backing up connected car service information stored in a connected car terminal onto a mobile terminal of a user in response to a request of the user. The method further enables restoring of the backup data stored in the user's mobile terminal to the connected car terminal. The connected car service information protection method includes establishing a communication connection with the mobile terminal by the connected car terminal, generating backup data for the connected car service information by the connected car terminal, and transmitting the backup data to the mobile terminal by the connected car terminal.

Abstract: Disclosed are methods for providing a telematics service, and in particular, methods for providing a telematics service to a replaced terminal after a telematics terminal installed in a vehicle is replaced. A method for operating a telematics terminal installed in a vehicle includes determining whether the telematics terminal is a replaced terminal when the vehicle is turned on, transmitting an enrollment request signal to a telematics center when the telematics terminal is the replaced terminal, processing service enrollment according to an enrollment message transmitted in response to the enrollment request signal, transmitting terminal information of the telematics terminal to the telematics center upon completing the service enrollment, and receiving a telematics service determined based on the terminal information.

Abstract: A method for controlling a communication mode in a telematics center associated with a telematics terminal through a mobile network is disclosed. The method includes receiving a voice over LET (VoLTE) setting state report message from the telematics terminal and determining whether VoLTE setting requires a change for the telematics terminal. When the VoLTE setting requires a change, a VoLTE setting change request message is transmitted to the telematics terminal.

Abstract: A system and a method is provided for providing vehicular telematics service. The system for providing a vehicular telematics service includes a vehicle terminal, in which an embedded application and a downloaded application are installed for receiving a telematics service. The vehicle terminal also includes a telematics unit for transceiving data for the telematics service through a wireless communication network. The system further includes a telematics center which applies sending information and reception information about a service target application to header information of a service request message when receiving a service request from a user terminal. The telematics center further transmits the service request message to the vehicle terminal, in which when the vehicle terminal receives the service request message, the vehicle terminal drives the embedded application or the downloaded application by referring to the reception information applied to the header information.
