Abstract

A method of controlling the operation of a mobile terminal having a multimedia data service capability is disclosed. The method initially includes establishing a call connection to a base station if a multimedia data service request is made by a mobile terminal user to receive multimedia data. Upon establishing the call connection, the mobile terminal sends a multimedia data service request signal to a base station and receives the corresponding multimedia data for a first predetermined period of time. Then, it disconnects the call connection and stops providing electric power to a signal receiving/transmitting part of the terminal after receiving a confirmation signal responding to the play-back period it has calculated earlier. Finally, it plays-back the received data for the play-back period. By using the present invention, an unnecessary connection fee can be eliminated, and the power being supplied to the mobile terminal while playing-back the data can be efficiently saved.

Claims

1. A method of controlling the operation of a mobile terminal having a multimedia data service capability, the method comprising:

establishing a call connection to a server if a data service request is made by a mobile terminal user to receive multimedia data;

sending a data service request signal to the server;

receiving said multimedia data from said server for a first given period;

calculating a play-back information required for playing-back said received multimedia data and sending an information signal including said calculated play-back information to said server, said play-back information required for play-back said received data being calculated based on an amount of said received data and a data processing rate of said mobile terminal;

receiving a confirmation signal responding to said sent information signal from said server; and

playing-back said received multimedia data for said play-back information.

2. The method of claim 1, further comprising:

disconnecting said call connection;

checking whether said received multimedia data includes a terminating signal upon completion of disconnecting; and

terminating a multimedia data service if said received data includes said terminating signal.

3. The method of claim 1, further comprising:

disconnecting said call connection;

checking whether said received multimedia data includes a terminating signal upon completion of disconnecting;

reestablishing said call connection; and

repeating the steps of sending a data service request signal to the server, receiving said multimedia data from said server for a first given period, calculating a play-back information required for playing-back said received multimedia data and sending an information signal including said calculated play-back information to said server, said play-back information required for playing-back said received data being calculated based on an amount of said received data and a data processing rate of said mobile terminal, receiving a confirmation signal responding to said sent information signal from said server; and

playing-back said received multimedia data for said play-back information, until said received data includes said terminating signal.

4. The method of claim 1, further comprising:

providing electric power to said mobile terminal before said call connection is established;

receiving a server signal from said server; and

registering at said server by sending a registration signal to said server.

5. The method of claim 1, wherein said mobile terminal user makes said data service request by pressing down one or more prescribed mobile terminal keys or buttons.

6. The method of claim 1, wherein said received data are initially stored in a memory of said mobile terminal.

7. The method of claim 1, wherein the playing-back said received multimedia data comprises:

storing said received multimedia data in a memory of said mobile terminal;

decoding said stored multimedia data to generate voice signals and image signals; and

generating corresponding sound and images to said mobile terminal user using said voice signals and image signals.
