That is, the voice of the user (caller) is input through the microphone, and the voice signal input through the microphone is input to the line-in terminal of the dual mode terminal 10 and is sampled as digital data and then carried. While transmitted to the storage server 15 via the Internet module, it is input to the CDMA modem and transmitted to the counterpart CDMA terminal 13. Therefore, the output line of the microphone must be connected to a line-in terminal and a CDMA modem.

On the other hand, the other party's voice is input through the CDMA modem, input to the line-in terminal through the output line of the CDMA modem, sampled into digital data, and then stored in the storage server through the portable Internet module. 15) while being input to the speaker and output to the user. Therefore, the output line of the CDMA modem should be connected to the line-in terminal and the speaker.

At this time, the line-in terminal may be implemented as two terminals or one terminal for receiving a voice signal from a microphone and a voice signal from a CDMA modem. Detailed configuration of the dual mode terminal 10 will be described later with reference to FIG. 5.

The storage server 15 stores the call data received from the dual mode terminal 10, and then retrieves and transmits the corresponding call data according to a reproduction request from the dual mode terminal 10. . In this case, a technology for storing voice data in the server may use a binary large object (BLOB) function of a database, which is a known technique.

In addition, the storage server 15 may store the call data received from the dual-mode terminal 10 in a wave (WAV) format or the like without special processing, and may be efficiently managed by the portable Internet 12. You can also convert and save to a compressed format such as (MP3). However, the dual mode terminal 10 receiving the call data from the storage server 15 uses a format that can be recognized and reproduced. The technology for converting voice data into MP3 (MP3) is a conventional technique that is known and practiced in various ways before this application, and thus a detailed description thereof will be omitted. The configuration of the storage server 15 will be described later in detail with reference to FIG. 6.

Make a voice call with 21. Each of the dual mode terminals 20 and 21 samples the user's voice received through the speaker as digital data according to a request for storing the contents of the call, and then, respectively, to the storage server 25 connected through the portable Internet 12. send.

That is, in the above-described embodiment, one dual-mode terminal 10 samples the contents of the conversation between the user and the other party, that is, the talk data and the sign data, as digital data and then transmits the digital data to the storage server 15. In another embodiment of the present invention as shown in Figure 2, each of the dual-mode terminal 20, 21 samples the user voice received through the speaker as digital data and transmits to the storage server 25, respectively.

The storage server 25 integrates the sound sources (voice data) received from the dual mode terminals 20 and 21 and stores them as one call data, and then reproduces the data from the dual mode terminals 20 and 21. Performs a function to retrieve and transmit the call data as requested.

At this time, in one embodiment as shown in FIG. 1, the complexity of the dual mode terminal 10 is increased while the voice of the talker and the receiver needs to be processed in one dual mode terminal 10. In another embodiment as shown in Fig. 2, since each of the dual mode terminals 20 and 21 to which the call path is connected processes the user voice, the complexity of the dual mode terminals 20 and 21 is reduced, and instead, each dual mode terminal ( The complexity of the storage server 25 for integrating the voice data received from 20, 21 and storing them as one call data is increased.

As another embodiment, when the dual mode terminal of the one side is requested to save the call content in a state in which the call path is connected between the dual mode terminals 20 and 21 of both sides, it transmits it to the opposite dual mode terminal. Then, each of the dual mode terminals 20 and 21 on both sides samples the voice signal received from the voice input unit (microphone) from the voice data sampling unit 504 as voice data, and then through the portable Internet processing unit 508. Transfer to storage server 25. Then, the storage server 25 integrates voice data received from the dual mode terminals 20 and 21 on both sides, generates call data, and stores the voice data corresponding to the user. At this time, the user data is included in the voice data transmitted from the dual mode terminals 20 and 21 of both sides requested to store the call contents. Accordingly, the storage server 25 extracts user information included in voice data received from dual-mode terminals 20 and 21 on both sides, and stores the generated call data to correspond to the extracted user information. .synthesis
