1. A 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 generating and transmitting a first alert message indicating a first state and a second alert message indicating a second state;
a Voice Message System (VMS) server for storing the voice message sent from the sender'"'"'s terminal; and
a Session Initiation Protocol (SIP) proxy server for storing the voice message on the VMS server when the recipient'"'"'s terminal is in the first state and for transmitting the stored voice message to the recipient'"'"'s terminal when the SIP proxy server receives a request message from the recipient'"'"'s terminal and when the recipient'"'"'s terminal is in the second state.

12. A method for enhancing a mobile communication terminal PTT service, the method comprising the steps of:
-
registering whether a recipient'"'"'s mobile communication terminal is in a first state or a second state; storing a voice message sent from a sender'"'"'s mobile communication terminal when the recipient'"'"'s mobile communication terminal is in the first state; and transmitting the stored voice message to the recipient'"'"'s terminal at the request of the recipient'"'"'s terminal when the recipient'"'"'s terminal is in the second state. - View Dependent Claims (13, 14, 15, 16, 17)

18. 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, wherein the recipient'"'"'s terminal generates and transmits a first alert message to the SIP proxy server to indicate the recipient'"'"'s terminal transitions to the first state, and wherein the recipient'"'"'s terminal generates and transmits a second alert message to the SIP proxy server to indicate the recipient'"'"'s terminal transitions to the second state. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)

26. A method for enhancing a mobile communication terminal PTT service, the method comprising:
-
transmitting a first alert message from a recipient'"'"'s mobile communication terminal to a Session Initiation Protocol (SIP) proxy server when entering a first state, wherein the SIP proxy server stores a voice message sent from a sender'"'"'s mobile communication terminal in response to the first alert message; transmitting a second alert message from the recipient'"'"'s mobile communication terminal to the SIP proxy server when transitioning to a second state; receiving at the recipient'"'"'s mobile communication terminal notification from the SIP proxy server that the voice message is stored, the notification being received in response to the second alert message; requesting transmission of the stored voice message via the recipient'"'"'s mobile communication terminal; and receiving the stored voice message from the SIP proxy server at the recipient'"'"'s mobile communication terminal in response to the request. - View Dependent Claims (27, 28, 29)
