摘要:
Provided is a method for operating multi-type beacons by a first terminal connected with at least one second terminal through short-range communication. The method includes checking at least one variable related to the second terminal, allocating one selected from a plurality of beacons having different characteristics to the second terminal, taking into account the checked variable, and transmitting the beacon allocated to the second terminal.

摘要:
A method and apparatus for supporting mobility of a mobile terminal in a Visible Light Communication (VLC) system. The method includes activating only necessary light sources for VLC considering the mobility of the mobile terminal, instead of using total light sources for VLC. Consequently, power consumption can be significantly reduced.
摘要:
A method and device for determining an output of a visible frame in at Visible Light Communication (VLC) device are provided. A first VLC device determines whether to permit a second VLC device to generate visible frames, and transmits, to the second VLC device, visible frame information indicating whether the second VLC device is permitted to generate the visible frames.

Proposed is a method for providing additional information to a mobile communication terminal by means of visible light communication in an information display device having an LED backlight unit. For this purpose, the method of the present invention comprises the steps of: receiving, from a mobile communication terminal, a request for additional information on an object in a content image when a content image is being displayed on a screen of an information display device; determining whether or not there exists additional information corresponding to the request; and controlling, if said additional information does exist, the light emission of the LED backlight unit so as to transmit said additional information in the form of visible light to the mobile communication terminal. Further, according to the present invention, it is possible to provide various additional information corresponding to the request from the mobile communication terminal.

A method for synchronizing converged address book personal information managed by a converged address book system with non-converged address book personal information managed by a non-converged address book system, which does not support a converged address book service, by a server apparatus supporting the converged address book service is provided. The method includes identifying a generation of a synchronization event for urging a synchronization between converged address book personal information corresponding to a user terminal and non-converged address book personal information corresponding to the user terminal, configuring synchronization personal information including at least a part of the converged address book personal information, and exporting the synchronization personal information to a non-converged address book system related to the user terminal.
摘要:
A method and apparatus are provided for outputting a visibility frame for a communication link connection during a communication link release in a Visible Light Communication (VLC) system. A transmitting-side VLC device determines a visibility frame output type according to a communication mode to be performed. The communication mode and the visibility frame output type are transmitted to a receiving-side VLC device. The receiving-side VLC device is communicated with according to the communication mode and it is determined whether a communication link is released while performing communication according to the communication mode. When the communication link is released, outputting a visibility frame according to the visibility frame output type.
摘要:
Provided is an apparatus and method for searching for address book information. To this end, the present invention, upon receiving a search request message for searching address book information from a client, checks a search preference, searches for the address book information based on the checked search preference, applies a priority to the found address book information to create a final search result, creates a response message including the created final search result, forwards the response message to the client, and updates the preset search preference based on the final search result, thereby providing a search result optimized for a user.
摘要:
Provided is an apparatus and method for setting disposition with respect to document information share. To this end, once a transmission-side server forwards a document forward request message including a document disposition rule with respect to a document to a reception-side server, the reception-side server checks a preference with respect to the document forward request message by using a preset user preference to notify a document change, and stores document data together with a disposition rule regarding the document data, such that efficient management and disclosure of private information forwarded to a user become possible and thus a CAB service can be easily and rapidly provided according to user's selection.
摘要:
A method and apparatus for allocating resources of a Visible Light Communication (VLC) terminal in a VLC system. The VLC terminal receives a beacon message from a base station, coordinates time synchronization with the base station, searches for an available wavelength channel, constructs available wavelength channel information, and transmits an initial access request using a basic time slot channel and a basic wavelength channel. The base station considers the available wavelength channel information and a current channel allocation condition, allocates an appropriate channel, and transmits channel allocation information to the VLC terminal. The VLC terminal and the base station communicate data with each other using an allocated time slot channel included in the channel allocation information and an allocated wavelength channel included in the channel allocation information.
