20080248761 | MOBILE COMMUNICATION TERMINAL FOR PTT AND METHOD FOR PROCESSING MISSED CALL INFORMATION THEREOF - The present invention relates to a mobile communication terminal for Push To Talk (PTT) and a method for processing missed call information thereof, which allows a receiver to check why an originator requested the PTT telephone call during the absence of the receiver through missed call information. The missed call information includes the voice of the originator requesting the PTT call, and the voice of the originator is output when confirmation of the missed call information is requested. | 10-09-2008 |
20100074155 | Mobile terminal and communication mode switching method thereof - A mobile terminal and communication mode switching method is capable of efficiently managing a data connection to a network via a wireless link when the mobile terminal switches between a master operation mode and a slave operation mode. A communication mode switching method determines whether a request for a second mode communication session is detected while the mobile terminal is in a first mode communication session with a network via a first interface. The system and method initializes and activates a second interface when a request for a second mode communication session is detected. The system and method also synchronize the first interface and the second interface, re-register a Mobile Internet Protocol (MIP) with the network, acquire an IP address as a consequence of the re-registration of the MIP, and communicate data with the network using the acquired IP address. | 03-25-2010 |
20100075708 | Method and system for notifying absence in PTT service, and portable terminal adapted thereto - A method and system for notifying a first portable terminal regarding the absence of a second terminal in a Push-To-Talk (PTT) service. The system allows a first portable terminal user to transmit an absence notifying message to the second portable terminal user, and displays an absent state of the first portable terminal user when the second portable terminal user requests a PTT connection with the first portable terminal user. Therefore, the system enables the second portable terminal user to recognize the absent state of the first portable terminal user. | 03-25-2010 |
