Abstract

A terminal-state-setting apparatus and a method using a distance between a portable communication terminal and a user are provided. The terminal-state-setting method in the portable communication terminal includes measuring a distance between the terminal and a user-distance-recognizing device using a radio communication; and setting a state of the terminal according to the measured distance value. The user does not have to manually set the terminal state through the menu setup, and the user state can be accurately reflected through a presence service.

measuring a distance between the terminal and a user-distance-recognizing device using a radio communication; and

setting a state of the terminal according to the measured distance value.

2. The terminal-state-setting method of claim 1, wherein the radio communication is one of Bluetooth, InfraRed Data Association (IrDA), Radio Frequency IDentification (RFID), and Ultra-WideBand (UWB) communication.

3. The terminal-state-setting method of claim 1, wherein the user-distance-recognizing device enables the radio communication and is embedded to an object carried along by a user.

4. The terminal-state-setting method of claim 1, further comprising:

searching for the user-distance-recognizing device using the radio communication when the terminal is powered on; and

registering the searched user-distance-recognizing device to a memory as a device for measuring the distance between the user and the terminal.

5. The terminal-state-setting method of claim 1, wherein the state of the terminal includes at least one of a ring/vibrate mode, a ring volume, and a presence status.

6. The terminal-state-setting method of claim 1, further comprising:

storing the measured distance value to the memory.

7. The terminal-state-setting method of claim 6, further comprising:

measuring the distance between the terminal and the user-distance-recognizing device using the radio communication after a certain time; and

calculating a change of the distance value using the measured distance value and a distance value measured before the certain time, and automatically changing the terminal state when the calculated distance value change is greater than a reference value.

8. The terminal-state-setting method of claim 7, further comprising:

entering a sleep mode for the certain time.

9. The terminal-state-setting method of claim 7, wherein the terminal state changing comprises:

when the calculated distance value change is greater than a reference value for changing the presence status of the terminal, generating and transmitting a PUBLISH message including presence status change information to a presence server.

10. The terminal-state-setting method of claim 7, wherein the terminal state changing comprises:

when the calculated distance value change is greater than a reference value for changing the ring/vibrate mode or the ring volume of the terminal, changing the ring/vibrate mode or the ring volume.

15. The terminal-state-setting apparatus of claim 1, wherein the state of the terminal includes at least one of a ring/vibrate mode, a ring volume, and a presence status.

11. A terminal-state-setting apparatus in a portable communication terminal, comprising:

means for measuring a distance between the terminal and a user-distance-recognizing device using a radio communication; and

means for setting a state of the terminal according to the measured distance value.

12. The terminal-state-setting apparatus of claim 11, wherein the radio communication is one of Bluetooth, InfraRed Data Association (IrDA), Radio Frequency IDentification (RFID), and Ultra-WideBand (UWB) communication.

13. The terminal-state-setting apparatus of claim 11, wherein the user-distance-recognizing device enables the radio communication and is embedded to an object carried along by a user.

14. The terminal-state-setting apparatus of claim 11, further comprising:

means for searching for the user-distance-recognizing device using the radio communication when the terminal is powered on; and

means for registering the searched user-distance-recognizing device to a memory as a device for measuring the distance between the user and the terminal.

16. The terminal-state-setting apparatus of claim 11, further comprising:

means for storing the measured distance value to the memory.

17. The terminal-state-setting apparatus of claim 16, further comprising:

means for measuring the distance between the terminal and the user-distance-recognizing device using the radio communication after a certain time; and

means for calculating a distance value change using the measured distance value and a distance value measured before the certain time, and automatically changing the terminal state when the calculated distance value change is greater than a reference value.

18. The terminal-state-setting apparatus of claim 17, wherein the means for changing the terminal state comprises:

means for generating and transmitting a PUBLISH message including presence status change information to a presence server when the calculated distance value change is greater than a reference value for changing the presence status of the terminal.

19. The terminal-state-setting apparatus of claim 17, wherein the means for changing the terminal state comprises:

means for changing the ring/vibrate mode or the ring volume when the calculated distance value change is greater than a reference value for changing the ring/vibrate mode or the ring volume of the terminal.

20. A terminal-state-setting apparatus comprising:

a terminal for measuring and storing a distance between the terminal and a user-distance-recognizing device using a radio communication, and setting a terminal state according to the measured distance value; and

21. The terminal-state-setting apparatus of claim 20, wherein the radio communication is one of Bluetooth, InfraRed Data Association (IrDA), Radio Frequency IDentification (RFID), and Ultra-WideBand and (UWB) communication.

22. The terminal-state-setting apparatus of claim 20, wherein the terminal state includes at least one of a ring/vibrate mode, a ring volume, and a presence status.

23. The terminal-state-setting apparatus of claim 20, wherein the terminal, when the terminal is powered on, searches for the user-distance-recognizing device using the radio communication and registers the searched user-distance-recognizing device to a memory as a device for measuring a distance between the user and the terminal.

24. The terminal-state-setting apparatus of claim 20, wherein the terminal, after a certain time, measures a distance between the terminal and the user-distance-recognizing device using the radio communication, calculates a distance value change using the measured distance value and a distance value measured before the certain time, and automatically changes the terminal state when the calculated distance change is greater than a reference value.
