Abstract: PURPOSE: A method for indicating the number of short messages transmitted from a mobile terminal is provided to allow a user to be informed of a charge according to SMS message transmission by recognizing the number of SMS messages transmitted from his/her mobile terminal. CONSTITUTION: A controller of a mobile terminal completes an SMS message by a user(110). The controller detects whether the user transmits the SMS message as created(120). If the user transmits the SMS message, the controller counts a value corresponding to a memory unit storing the number of transmitted SMS messages(130). The controller determines whether the user selects a menu indicating the number of the transmitted SMS messages through a key input unit(140). If the user selects the menu indicating the number of SMS messages, the controller displays the number of transmitted SMS messages on a display unit(150).

Abstract: A method for generating a visible signal for a data transmission frame and an apparatus therefor are provided to perform high-speed communication with the small power and low cost in the visible light communication network having a limited distance. An apparatus for generating a visible signal receives specific data consisting of a plurality of frames from a transmission side(510). A VLC controller converts an RSSI signal measured from the transmission side into a digital signal(512), and checks RSSI signals of each corresponding frame whenever each frame of the specific data is sequentially received from the transmission side(514). The corresponding RSSI value of a received frame is a preset critical value or greater(516), the VLC controller produces visible signals differentiated according to each RSSI state, and then transmits the generated signals to the transmission side(518).

A first input/output unit(210) inputs a first optical signal(201) which plural odd channels are multiplexed and outputs a second optical signal(202) which plural even channels are multiplexed. A second input/output unit(220) outputs the added or dropped first optical signal(201) and inputs the second optical signal(202). A light waveguide lattice(240) has first and second terminals composed of plural ports, and multiplexes the added or dropped odd channels of the first optical signal and the added or dropped even channels of the second optical signal, and then outputs them to the second input/output unit and the first input/output unit, respectively. An optical coupler(230) amplifies the first and second optical signals input from the first and second input/output units, and then outputs them to the first and second terminals, respectively.
