Abstract

An apparatus and method for managing a sound volume of a wireless connection device in a mobile communication terminal are provided. The method includes pre-storing a sound volume level of the wireless connection device with respect to each system supported by the mobile communication terminal, and when a call is generated, requesting to determine a sound volume by transmitting to the wireless connection device a sound volume level of a system in which the call is generated among the sound volume levels pre-stored for the respective systems.

Claims

1. A method in a mobile communication terminal for supporting a plurality of communication systems, the method comprising:

storing a plurality of sound volume levels, wherein a sound volume level is stored by;

selecting a communication system, among a plurality of communication systems, supported by the mobile communication terminal;

selecting a wireless connection device among a plurality of wireless connection devices that can be connected to the mobile communication terminal via near field communication techniques;

receiving a sound volume level for the selected communication system and the selected wireless connection device; and

storing the received sound volume level;

upon detecting a call connection,

identifying a first communication system in which the call connection is detected;

connecting the mobile communication terminal to a wireless connection device through a second communication system;

selecting a first sound volume level corresponding to the identified first communication system and the connected wireless connection device among the plurality of sound volume levels;

transmitting a sound signal to the connected wireless connection device based on the first sound volume level through the second communication system;

if a sound volume is changed during the call connection, updating the first sound volume level based on the changed sound volume.

2. The method of claim 1, wherein the near field communication techniques include a Bluetooth communication.

3. The method of claim 1, wherein the mobile communication terminal supports the plurality of communication systems using Subscriber Identity Module cards.

4. A mobile communication terminal comprising:

at least one communication unit configured to process transmission/reception of a signal in the mobile communication terminal supporting a plurality of communication systems;

a storage unit configured to store a sound volume level with respect to each of the plurality of communication systems; and

a controller configured to select a communication system, among a plurality of communication systems, supported by the mobile communication terminal, select a wireless connection device among a plurality of wireless connection devices that can be connected to the mobile communication terminal via near field communication techniques, to receive a sound volume level for the selected communication system and the selected wireless connection device, to store the received sound volume level in the storage unit, upon detecting a call connection, to identify a first communication system in which the call connection is detected, to connect the mobile communication terminal to a wireless connection device through a second communication system, to select a first sound volume level corresponding to the identified first communication system and the connected wireless connection device among the stored sound volume levels in the storage unit, to transmit a sound signal to the connected wireless connection device based on the first sound volume level, and if a sound volume is changed during the call connection, to update the first sound volume level based on the changed sound volume.

5. The mobile communication terminal of claim 4, wherein the near field communication techniques include a Bluetooth communication.

6. The mobile communication terminal of claim 4, wherein the mobile communication terminal supports the plurality of communication systems using Subscriber Identity Module cards.
