The present invention provides a wireless terminal having a voice call function between wireless terminals through a mobile communication network, the predetermined data or predetermined applets (or programs) defined to provide a predetermined additional service during a voice call to the wireless terminal. After being provided in association with a key tone (or a signal / data matched with the tone), a predetermined key tone (or tone) from a server or device on the mobile communication network and / or network is provided through a corresponding communication channel in at least one wireless terminal. The present invention provides a key tone relay server, a wireless terminal, and a recording medium for receiving and reading a matching signal / data) and providing an additional service through predetermined data or applets (or programs) matching the same.

In a conventional landline telephone system using a Public Switched Telephone Network (PSTN), the landline telephone includes a Private Automatic Branch eXchange (or Private Automatic Branch eXchange if connected to a local telephone network through a predetermined wireline); PABX)), and the caller keeps the handset close to his or her ear (or mouth) while picking up the handset of the wireline and connecting a communication channel with a predetermined caller. A dial tone that outputs certain information required during the channel connection process (e.g., a dial tone when the handset is picked up to confirm that the telephone and the exchange are connected). Busy tone output when call is requested, Ringback tone output during call channel connection e) and so on).

In addition, in the conventional wired telephone system as described above, when a receiving calling device telephone number is input from a predetermined calling party calling device for a call channel connection, the telephone number is a complex frequency code as shown in FIG. The signal is matched with a predetermined tone through a Mutiple Frequency (DTMF) and transmitted to the exchange.

Referring to Figure 1, the keypad of the landline telephone is provided in the form of a "4x3" matrix, the row with the "1, 2, 3" push button generates a frequency of 697 Hz, the "4, 5, 6" push button This row generates a frequency of 770 Hz, the row with "7, 8, 9" pushbuttons generates a frequency of 852 Hz, and the row with a "*, 0, #" pushbuttons has a frequency of 941 Hz And a column with a “1,4,7, *” pushbutton generates a frequency of 1209 Hz, and a column with a “2,5,8,0” pushbutton generates a frequency of 1336 Hz. The heat generated and provided with the “3,6,9, #” pushbuttons is defined to generate a frequency of 1477 Hz.

For example, when a push button '1' of the landline telephone keypad is clicked, the landline telephone generates a sinusoidal current corresponding to a synthesized tone of 697 Hz and 1209 Hz based on the complex frequency code and transmits it to the exchange. The exchanger reads through a band-pass filter (BPF) to confirm that the sinusoidal wave current corresponds to '1'. A detailed specification of this is defined in Recommendation E.180 / Q.35 of the International Telecommunications Union.

On the other hand, in the case of mobile communication in which a communication channel is connected in a wireless digital manner based on a code division multiple access (CDMA) stack in Korea, a call connection procedure for communication channel connection does not follow the complex frequency code scheme as described above. However, when the receiving call device is a predefined answering device (for example, a calling device using a “700” station number) for compatibility with an automatic response service (ARS) provided from a conventional landline telephone. In the case of inputting the numeric keys of the key input means provided in the wireless terminal, only the function of arbitrarily generating a predetermined key beep according to the complex frequency code and transmitting it to the answering machine is provided.

However, in the key ring tone generation and transmission function according to the complex frequency code system provided in the wireless terminal as described above, the key ring tone generation is limited when the receiving side call device is a predefined answering machine. Like the voice signal for the voice call, the key tone is encoded based on the CDMA stack and provided to the answering machine in the form of digital data via a mobile communication network, and the coded key tone is reversed by the answering machine. The mobile communication network to which the wireless terminal is connected is not provided with a complex frequency code reading function as in a conventional public switched telephone network by tracking and reading a key tone.

In addition, the key tone coded based on the CDMA stack is digitized through a predetermined encryption and compression process for security reasons and / or for the efficiency of data processing, like a voice signal. It includes a problem that is not solved by having a complex frequency code reading function.
