Abstract: An audio apparatus adaptable to a user position is provided. The audio apparatus may include a plurality of sub-modules placed at separate locations from one another, each sub-module of the plurality of sub-modules including a loudspeaker configured to generate sound and a communicator configured to perform communication. The first sub-module among the plurality of sub-modules may include a processor that processes an audio signal to be output as sound through the loudspeaker of the first sub-module, determines a user's position with respect to each of the plurality of sub-modules, and changes a state of the sound being output from the loudspeaker of the first sub-module in accordance with the determined position of the user.

Abstract: User equipment includes a storage unit for separately storing map data, POI (Point Of Interest) information, and location information of the POI information on the map data, a map output unit for displaying the POI information on a screen based on the location information of the POI information so that the POI information is overlapped with the map data in parallel to the lateral axis of the user equipment, and a rotation angle calculating unit for calculating a rotation angle for the rotation of the map data. The map output unit rotates the map data and the POI information, which are displayed on the screen in an overlapping state, according to the rotation angle so that the POI information is disposed in parallel to the lateral axis of the user equipment after rotation.

Abstract: Disclosed is a system and a method for session reestablishment between a client terminal and a server for a messenger service. In a session reestablishment system including a client terminal capable of accessing a communication network, a session information database and a server for providing a messenger service to the client terminal, the client terminal sends a synckey exchanged and stored during previous access to the server when sending a request for session reestablishment (reaccess) to the server after lapse of a predetermined time period from termination of the previous access due to log-off or timeout. The server searches the session information database to detect last session information corresponding to the client terminal based on the synckey, compares the last session information with current session information to detect any updated data, and sends only the updated data to the client terminal.

Abstract: An apparatus and method for synchronizing data between a terminal and a server. The apparatus synchronizes presence attribute data when the terminal and the server are connected to each other to establish a messenger service between them. The client terminal requests presence attribute data to be updated from a server when it is reconnected to the server having been previously connected to the client terminal to perform the messenger service, and updates presence attribute data stored at a time of a previous connection upon receiving the presence attribute data to be updated from the server. The server receives a presence attribute data request to be updated from the client terminal, and transmits only updated presence attribute data, created after releasing the previous connection, from among current presence attribute data to the client terminal.

Abstract: A system and method for providing messenger services is disclosed. The system includes a presence information database (DB), a terminal, and messenger server. The presence information database (DB) stores messenger status information of each of a plurality of subscribers subscribing to the messenger services, and registration information shared between the subscribers. In response to a request of the first subscriber, the terminal stores a first subscriber's schedule therein, and transmits the first subscriber's stored schedule and a change request signal of messenger status. The messenger server receives the schedule and the change request signal of messenger status information based on the schedule and changes first subscriber's messenger status information in response to the schedule.

Abstract: Disclosed herein is an apparatus and method for managing schedule information in a mobile communication terminal that implements a schedule management function allowing a user to include a variety of information associated with a call signal (i.e. call history information) or transmission/reception messages generated by an SMS, EMS, MMS type message within schedule information, and is to store/manage the schedule information including the call history information and the transmission/reception messages. A schedule information encoder is provided for encoding call history information and transmission/reception messages stored in different formats in a single schedule information format.

Abstract: Provided are a method of synchronizing data between a server and a user terminal using a messenger service system and a system using the same. In a data synchronization system including a messenger server for storing at least one contact list having information on terminals belonging to one messenger group, and a synchronization markup language (SyncML) server for synchronizing the information on the terminals, upon receiving a request for synchronization of information data to be shared by the group from a first terminal, the SyncML server stores the information data. Upon receiving an information data synchronization request from a second terminal, the Synch ML server requests the messenger server for a contact list of the second terminal. If it is determined that the second terminal belongs to the group to which the first terminal belongs, the SyncML server synchronizes the terminals with respect to the information data.
