Abstract: A method and an apparatus for detecting a battery state of an electronic device are provided. The electronic device includes a battery, a charger circuit for charging the battery, a measurement circuit for checking a state of the battery, and a processor configured to charge the battery using the charger circuit, determine whether the charging operation satisfies a preset condition, when the charging operation satisfies the preset condition, obtain first state information of the battery using the measurement circuit, determine an abnormal state of the battery at least based on a difference between the first state information and second state information which is obtained when the preset condition is satisfied before the first state information is acquired, and output notification information regarding the abnormal state.

Abstract: An electronic device and a method of providing a notification on a wireless charging state in an electronic device are provided. The method includes wirelessly charging the electronic device by using power received from an external device; checking a state of the wireless charging; when the state of the wireless charging corresponds to a certain condition, determining whether the electronic device is used by a user by using at least one sensor; and providing a notification based on whether the electronic device is used by the user.

Abstract: A method and apparatus for synchronizing Digital Multimedia Broadcasting (DMB) are provided. An operation method of a first Mobile Station (MS) for synchronizing DMB includes sending a broadcast channel synchronization request message to a second MS, receiving a broadcast channel synchronization request grant message from the second MS, after broadcast channel synchronization, receiving information on a broadcast channel viewed by the second MS, tuning to the broadcast channel viewed by the second MS based on the broadcast channel information received from the second MS, and displaying the broadcast channel viewed by the second MS.

Abstract: While a user uses one service in a digital multimedia broadcasting receiving terminal, there is implemented a function for suspending the service currently being used and enabling a different service to be used when the different service is provided. A function for enabling a call service to be used during a broadcast service is implemented. A call screen is displayed in a state in which a broadcast service connection is maintained, such that the user can use a new call service without stopping the broadcast service currently being used. In this concurrent service, switching between the call screen and a broadcast screen is possible. This display method can prevent images of the respective services from overlapping with each other and can provide one service without stopping another service.

Abstract: A communication among participants in on-line virtual environments is disclosed. The communication with reality among the participants is effected in the diverse virtual environments such as an on-line game, chatting, etc., by converting a text message from a specified person into a speech having its own tone during the text message communication among the participants, and by reproducing the converted message through a receiver's speaker with a sound effect added thereto. The on-line communication by speech among the participants is effected without affecting the load of the network by converting the text message received in a user terminal into the speech using a text-to-speech converter, and by reproducing the converted speech through the speaker.
