摘要： A method and apparatus for performing a navigation service in a mobile terminal is provided. Map information and an IDentification (ID) of an information spot, which is connected to a map server, are received from the information spot. A current position is determined. The map information and the current position are displayed A destination input by a user is received. An optimal path from the current position to the destination is calculated and displayed by using the map information. When the mobile terminal receives an ID of a general spot from the general spot, a current position of the mobile terminal is re-determined. When the re-determined current position is on the optimal path, the optimal path is updated and the updated optimal path from the re-determined current position to the destination is displayed.

摘要： A reconnection method and device for a peripheral interface using VLC provide a protocol for when a communication link between a primary device and a secondary device is disconnected. The primary device generates an R-XID message including reconnection information and a warning indication signal indicating the disconnection. The secondary device aligns the communication link with the primary device using the warning indication signal, receives the R-XID message from the primary device by the secondary device, and transmits an R-XID response message for the R-XID message to the primary device.

摘要： A method for communication link connection in a data transmission between devices using visible light communication (VLC) that can provide a visible indication prior to establishing a communication link between the devices. The method includes activating a VLC mode by a first VLC apparatus in order to transmit the data; scanning other apparatuses to establish a communication link with a second VLC apparatus; requesting a communication link to the second VLC apparatus in order to transmit the data; and receiving a response, indicating whether data can be received from the second VLC apparatus, and establishing communication link connection. A user can easily recognize the visual indication before the establishment of the communication link, providing an opportunity for the user to arrange the apparatus for optimal communication distance/angle from another device, and for a status of the communication.

摘要： A system and method for continuing a communication link while maintaining visibility in visible light communication. A frame is transmitted by a sender for establishing a communication link before data transmission to a receiver by a sender. A receiver sends a response frame that reports on establishment of the communication link prior to data transmission by the sender. A data frame containing information is transmitted by the sender to the receiver. An acknowledgment frame is transmitted to the sender in response to the data frame. A disconnect frame is transmitted by the sender which is acknowledged by the receiver. A visible sequence is transmitted during a time period when the sender and the receiver do not transmit respective frames for communication to maintain visibility between two devices that may be communicating otherwise by, for example, infrared communication.
