The present invention relates to a remote dialing system, and more particularly, to wireless dialing through voice input by calling a dialing server located remotely through a wireless earset capable of transmitting and receiving wireless data with a mobile communication terminal. To a remote dialing system.

Mobile communication terminals such as cellular phones, PCS phones, PDAs, and local area communications are becoming more compact and lighter thanks to the development of communication technologies. These mobile communication terminals continue to increase in size due to their portable and mobile convenience. Doing.

The earset used in the mobile communication terminal is connected to the mobile communication terminal and outputs voice data transmitted from the mobile communication terminal through an ear speaker, and then inputs voice data input through the ear microphone. , So that the user can make a phone call without holding the mobile terminal directly.

Conventional earsets are usually connected to the ear jacks of the mobile communication terminal through a wire to input and output voice. In the case of a wired wire, the length of the earset is limited, so the mobile communication terminal should be stored near the user and the wires are twisted or tangled, causing inconvenience. Sometimes.

Hereinafter, a process of operating the remote dialing system according to the present invention having the above configuration will be described.

6A and 6B are flowcharts illustrating a process in which voice dialing is performed through a remote dialing system according to an exemplary embodiment of the present invention.

First, when the mobile communication terminal wireless module is coupled to the mobile communication terminal and the power is turned on (step S100), the power level generator of the mobile communication terminal wireless module periodically generates a power signal to be wirelessly transmitted to the outside through the RF transmitter. (Step S110), the power level detector of the earset wireless module detects the power level of the wireless power signal received through the RF receiver (step S120).

The earset wireless module controller of the earset wireless module compares the power level detected through the power level detecting unit with a reference power level stored in the memory (step S130), and when the detected power level is smaller than the reference power level, The call right signal indicating that the ear right of the wireless module is out of the right to generate a signal is transmitted to the earset control unit, accordingly the warning signal is output to the speaker and the display unit (step S131).

If the detected power level is greater than the reference power level, this means that the mobile communication terminal wireless module and the earset wireless module are located in a communication zone, and the mobile communication terminal wireless module and the earset wireless module can normally transmit and receive wireless data.

In a state where the mobile communication terminal wireless module and the earset wireless module are located in a normal call zone, the user selects a call button provided in the key input unit to perform voice dialing through the wireless earset (step S140).

According to the selection of the call button of the wireless earset, the earset control unit generates a call connection signal to be connected to the dialing server and transmits it to the earset wireless module, and the earset wireless module control unit of the earset wireless module is a call connection transmitted from the earset control unit through the RF transmitter. The signal is converted into Bluetooth data and then wirelessly transmitted to the outside (step S150).

Bluetooth data wirelessly transmitted from the earset wireless module of the wireless earset is received through the RF receiving unit of the mobile communication terminal wireless module to demodulate the original call connection signal, and then transmitted to the control unit of the mobile communication terminal through the input / output port (step S160). ).

The control unit of the mobile communication terminal grasps the receiving address of the dialing server included in the call connection signal transmitted from the wireless communication terminal wireless module, and dials it to establish a communication line between the dialing server, the mobile communication terminal and the wireless ear set (step S170). ).

On the other hand, the calling party identification unit of the dialing server grasps the caller information included in the call connection signal transmitted from the wireless earset through the mobile communication terminal, and the member management unit determines whether the caller is a member registered in the database through the identified caller information. (Step S180). If it is not a registered member, the automatic voice guidance unit guides the caller to register as a member before using the remote dialing service (step S181).

On the other hand, if the caller is determined to be a registered member, the automatic voice guide of the dialing server instructs the caller to input the callee's voice to which the call is to be connected (step S190), and the caller receives the voice corresponding to the callee through the microphone of the wireless earset. If it is input (step S200), the voice recognition unit of the dialing server recognizes the corresponding voice and searches whether there is a receiver's telephone number corresponding to the voice in the database of the caller member (step S210).

If there is no recipient telephone number corresponding to the voice (step S220), the automatic voice guide of the dialing server informs that the receiver information corresponding to the voice is not registered in the database unit (step S221), and matches the corresponding voice. After inquiring whether to register a new recipient's telephone number (step S222), when the caller wishes to register with the recipient's telephone number and inputs the recipient's telephone number, it registers it with the recipient voice in the database and registers the new recipient information. (Step S223).

When the receiver information corresponding to the voice is present in the database unit, the receiving number calling unit of the dialing server retrieves the recipient telephone number (step S230) and dials (step S240), so that a communication line is established between the caller and the receiver using the wireless earset. A telephone call is made in connection (step S250).

When the telephone call is terminated (step S260), the caller's call history, for example, receiver information and call time, is stored in the database unit of the dialing server, and then the telephone call through remote dialing between the caller and the receiver is terminated (step S260). S270).

As described above, the remote dialing system using the wireless voice recognition according to the present invention can access a dialing server connected to a mobile communication terminal through a network through a wireless earset and perform remote dialing through voice input.

As described above, the remote dialing system through wireless voice recognition according to the present invention enables wireless data transmission and reception via Bluetooth between the mobile communication terminal radio module detachably coupled to the mobile communication terminal and the earset radio module provided in the wireless ear set. In addition, even in a mobile communication terminal that is not equipped with a wireless module, the mobile communication terminal wireless module can be combined to perform wireless communication with the wireless earset, and the voice provided by the dialing server connected through the network with the mobile communication terminal through the wireless earset. Remote dialing service can be provided through input. In addition, it is possible to protect the user from the electromagnetic waves generated from the mobile phone by holding the mobile phone directly in hand and not making or receiving calls.
