The present invention relates to a method for outputting a caller's voice of a mobile communication terminal, and more particularly, to output a caller's voice when a call signal is received at a receiving terminal so that the caller's voice can be clearly identified. It is about.

Due to the development of the telecommunications industry and the rapid expansion of mobile communication services, many people are carrying mobile communication terminals, and in order to meet the various needs of users to improve their functions, play music files, use of wireless Internet, and e-mail in addition to mobile wireless telecommunication functions. And other functions are added to the mobile communication terminal.

In recent years, a so-called coloring service, which represents a receiver's personality by replacing a ringback tone with music and a function capable of implementing various ringtones according to a user's taste, has also become popular. In addition, a caller indication service in which a telephone number of a calling terminal is displayed on a display window of a receiving terminal when receiving a call signal is widely used.

Looking at the conventional call process using such a mobile communication terminal as follows. When a call signal is generated from the originating terminal, the call signal is transmitted to the receiving terminal through the base station and the exchange. When a call signal is received through the antenna of the receiver terminal, the terminal controller of the receiver terminal causes the terminal to vibrate or ring through a predetermined interlocking program. In this state, when the user of the receiving terminal presses a receiving button or the like, a full-fledged call proceeds. At this time, when using the caller ID service, the calling party's telephone number is displayed on the display window in addition to the vibration and ring tone.

In the conventional call process described above, the caller can be identified only after receiving a call signal from the receiving terminal and pressing the receive button. Of course, when using the caller display service, the basic information about the caller can be obtained by checking the caller's phone number, but in this case, the display window of the terminal must be checked, and the phone number displayed on the display window is the user of the receiving terminal. If you do not know was only vague information.

The present invention has been made to solve the above problems, and provides a caller voice output method of the mobile communication terminal that can clearly identify the caller by outputting the caller's voice when a call signal is received at the receiving terminal. There is a purpose.

In order to achieve the above object, a caller voice output method using a mobile communication terminal according to the present invention comprises a step of generating a call signal from a calling terminal and transmitting it to a receiving terminal through a base station, and the calling terminal and the receiving terminal. When the call connection is successful, the first terminal establishes a first call connection state, and the receiving terminal outputs a voice generated from the calling terminal through a speaker; and when a key input signal such as a receiving button of the receiving terminal is generated, the receiving terminal receives the received call. And establishing a second call connection state in which a call between the side terminal user and the originating terminal user is performed.

Preferably, prior to the step of outputting the voice generated from the calling terminal through the receiving terminal speaker, transmitting a message indicating that the receiving terminal is in a first call connection state to the calling terminal. can do.

According to a feature of the present invention, when the call connection is successful in the call process between the calling terminal and the receiving terminal, instead of notifying the receiving notification signal such as a ringtone from the receiving terminal, the caller's voice is output so that the caller is correctly identified. It becomes possible.

Hereinafter, a caller voice output method of a mobile communication terminal according to the present invention will be described in detail with reference to the accompanying drawings. 1 is a block diagram of a wireless network for implementing a caller voice output method using a mobile communication terminal according to the present invention, Figure 2 is a block diagram of a mobile communication terminal for implementing a caller voice output method according to the present invention 3 is a flowchart illustrating a caller voice output method using a mobile communication terminal according to the present invention.

First, as shown in FIG. 1, a wireless network for implementing a caller voice output method using a mobile communication terminal according to the present invention is largely provided with a mobile communication terminal 101 equipped with a caller voice output authentication module and a mobile communication terminal 101. A base station 110 and a switch 102 that mediate wireless communication between the < RTI ID = 0.0 >

The base station 110 controls a base station transmission system (BTS) 112 for performing a wireless connection between the mobile communication terminals 101 and a plurality of base station transmission systems 112 and performs call processing. And a base station controller (BSC) 111 that performs call mobility management and the like. In addition, the base station may be provided with a predetermined database for storing information about the specific mobile communication terminals subscribed to the caller voice output service according to the present invention among the subscribed mobile communication terminals. Specifically, the predetermined database may be embodied as a home location register (HLR). The mobile switching manager (MSC) 102 is responsible for transmitting and receiving data and control signals between other communication networks such as a public switched center (PSTN), an internet network, or between lower networks of base stations of the same operator. Do this. The switch 102 is connected to a plurality of base stations 110, and is responsible for the transmission and reception paths of calls and user data between base station lower networks of the same mobile communication provider.

On the other hand, the mobile communication terminal for implementing the caller voice output method according to the present invention is largely a combination of the terminal control unit 201, data memory unit 203, wireless transceiver 202 and the caller voice output authentication module 204 Is done.

The terminal control unit 201 forms a predetermined communication connection relationship with all components of the mobile communication terminal to control overall operation of the mobile communication terminal, and the data memory unit 203 operates the mobile communication terminal. It stores a variety of data generated by the operation of the program and the mobile communication terminal required for. The wireless transceiver 202 transmits a signal received through the antenna 209 to the terminal controller 201 or transmits a signal generated from the terminal controller 201 to the base station 110 through the antenna 209. It performs the role of printing.

Meanwhile, the caller voice output authentication module 204 interoperates with a predetermined database that stores information on a mobile communication terminal subscribed to the caller voice output service in the base station 110 under the control of the terminal controller 201. When receiving a call from the wireless transceiver 202, the calling party determines whether the calling party has subscribed to the caller voice output service.

In addition to the above components, the codec 206 and the mobile communication terminal, which convert a voice input from the microphone 208 into a digital signal or convert a digital signal such as a ring tone or voice into an analog signal and output the same to the speaker 207. The display window 205 and the like that serve to display the operation performance state of the is further provided.

The method of outputting a caller's voice using a mobile communication terminal and a wireless network having such a configuration will be described in detail as follows.

First, when a call signal is generated from the calling mobile terminal, the corresponding call signal is transmitted to the base station 110 (S301). The base station 110 searches for the receiving terminal corresponding to the call signal input from the calling terminal in cooperation with the switch 102 and allocates a channel to transmit the calling signal of the calling terminal to the corresponding receiving terminal.

When the call signal is received by the wireless transceiver 202 through the antenna 209 of the receiver terminal and transmitted to the terminal controller 201, the caller voice output authentication module 204 is controlled by the terminal controller 201. In connection with a predetermined database or a separate home location register in the base station 110, the originating mobile communication terminal authenticates whether or not the subscriber's voice output service is subscribed to (S302). The caller voice output service may be made through a normal subscription procedure or the like as an additional service in other mobile communication terminals.

If the calling terminal is subscribed to the caller's voice output service, the calling terminal and the receiving terminal succeed in call connection and proceed to the call connection state (S303). If one of the calling terminal or the receiving terminal is not subscribed to the caller's voice output service, a call connection sound will be generated in the calling terminal by waiting for a call connection as in a normal call process. .

Meanwhile, the call connection state is a first call connection state, and does not mean a state in which the calling user and the receiving user talk to each other, but when the user of the calling terminal speaks while the call is connected, the caller's voice is used. The state output to the speaker 207 via the codec 206 or the like of the receiving terminal, that is, the audio path of the receiving terminal is opened (S304). In a conventional call process, a ring tone is output from a receiving terminal when a call connection is successful, but in the present invention, the caller's voice is output instead of the ring tone.

At this time, if the call connection is successful, a message indicating that the first call connection state is established may be transmitted to the calling terminal. Based on the message as described above, the caller may speak a predetermined voice to the receiver terminal, for example, an introduction or a purpose of the call. Thus, the receiver terminal user may acquire accurate information about the sender. It becomes possible.

In such a first call connection state, when the user of the receiving terminal presses a predetermined button, for example, a receive button of the key input unit, a call process between the authentic caller and the receiver, that is, the second call connection state, is performed ( S305).

The caller voice output method of the mobile communication terminal according to the present invention has the following effects.

When the call connection is successful in the call process between the calling terminal and the receiving terminal, the caller's voice can be outputted instead of notifying a receiving notification signal such as a ring tone from the receiving terminal, so that the caller can be accurately identified.
