Abstract
Disclosed is a system, apparatus, and method for enhancing a mobile communication terminal PTT service which includes a Voice Message System (VMS) server for storing a voice message sent from a sender's terminal when a recipient's terminal is in a receive-not-ready state; and a Session Initiation Protocol (SIP) proxy server for transmitting the stored voice message to the recipient's terminal at the request of the recipient's terminal.
Claims26
An system for enhancing a mobile communication terminal PTT service, the system comprising:
- a sender's mobile communication terminal for transmitting a voice message;
- a recipient's mobile communication terminal for receiving a stored voice message;
- a Session Initiation Protocol (SIP) proxy server for transmitting the stored voice message to the recipient's terminal when requested by the recipient's terminal;
- and
- a Voice Message System (VMS) server for storing the voice message sent from the sender's terminal responsive to whether a recipient's terminal is in a first or a second state.
A method for enhancing a mobile communication terminal PTT service, the method comprising the steps of:
- storing a voice message sent from a sender's mobile communication terminal when a recipient's mobile communication terminal is in a first state;
- and
- transmitting the stored voice message to the recipient's terminal at the request of the recipient's terminal.
An apparatus for enhancing a mobile communication terminal PTT service, the apparatus comprising:
- a Session Initiation Protocol (SIP) proxy server for receiving a voice message from a sender's mobile communication terminal and for transmitting a stored voice message to a recipient's mobile communication terminal when requested by the recipient's terminal;
- and
- a Voice Message System (VMS) server coupled with the SIP proxy server for storing the voice message sent from the sender's terminal responsive to whether the recipient's terminal is in a first or a second state,
- wherein the SIP proxy server stores the voice message on the VMS server when the recipient's terminal is in the first state and transmits the voice message to the recipient's terminal when the recipient's terminal is in the second state.
