  • Internet protocol terminal and method of providing short message service in busy state
    Publication number: 20050047437
    Abstract: A Short Message Service (SMS) of an Internet Protocol (IP) terminal to which a call is set up via a network according to a Voice over Internet Protocol (VoIP) effects voice communication. While the call is set up via the network according to VoIP to effect voice communication, the IP terminal either exchanges character information with a correspondent IP terminal to which the call is set up, or, when a call set-up request has been received from a third IP terminal, exchanges character information with the third IP terminal sending the call set-up request while continuing to maintain the voice communication.
