The telephone caller may make a call through the switching unit 100 using the wired terminal 10 of the wired subscriber and the mobile communication terminals 20 and 21 of the wireless subscriber. In this case, the mobile communication terminals 20 and 21 may be cellular phones, personal communication service phones (PCS), city phones (CT-2), or the like. In addition, the computer 11 may download the e-mail by connecting the subscriber of the wired terminal 10 to the mail server 15.

Various call formations may be made between the wired terminal 10 and the mobile communication terminals 20 and 21. For example, a call can be made between wired subscriber 10 and wireless subscriber 20 or between wireless subscriber 20 and wireless subscriber 21. The long-distance switch 12 interprets the dial impulse transmitted to the wired switch (station) and transmits data to a communication network such as a public switched telephone network (PSTN) network or a mobile switching center (MSC) 110 through a trunk line, Conversely, data is received and sent to the wired terminal. Switching unit 100 is a wired / wireless complex digital switchboard that performs intelligent network service in conjunction with other networks, and performs identification management, location registration, and location update functions for subscribers such as location information, subscriber number, and terminal routing number for each subscriber. It serves as an interface between the Visitor Location Resistor (VLR) 120 and the base station 13 and the MSC, handles handoff and base station management, extracts, stores and transmits data on the wireless network. A base station controller (BSC) 130 that performs channel assignment and release for each terminal and a home location register (HLR) 140 are included. The HLR 140 combines subscriber authentication key and random number as a subscriber authentication algorithm when establishing a call for authentication, service logic processing unit 141 in charge of location registration and deletion, subscriber information processing, error recovery, call processing, and additional services. The subscriber authentication processing unit 142 encrypts the subscriber message using an encryption key made by combining the subscriber authentication key with a random number, and creates and manages a terminal list to prevent the use of an illegal terminal. A terminal authentication processing unit 143 for confirming permission items, and a database 144 for storing subscriber information and location information, authentication related parameters, terminal information, and the like.

The base station 13 performs an interface operation connecting the terminals 20, 21 and the MSC 110 by converting baseband signal processing, wireless signal transmission, and wired / wireless conversion.

The call contents storage / transmission unit 200 is provided with a call contents storage process 210 for receiving the call contents from the MSC 110 and storing them, a voice recognition module for converting the stored call contents into a text, and a module for converting the recognized voice into text. Voice to Text conversion process 211, which consists of an e-mail sending process 212 for sending mail to the mail server 15 as a mail page having a predetermined format.

2 is a data flowchart for explaining an embodiment of the present invention.

When the mobile terminal 20 generates a call to call another mobile terminal 21, the MSC 110 requests the mobile terminal 20 for the identification number, and the mobile terminal 20 delivers the identification number. The identification number is sent to the terminal information processing unit 143 to check whether or not the defective subscriber and the stolen terminal are allowed. In addition, as a procedure for confirming whether the subscriber is a valid subscriber, the terminal and the base station verify that the secret data shared by the same is authenticated by the legitimate subscriber (S21). After authentication, in order to prevent eavesdropping of call contents, encryption is performed on transmission / reception data between the base station controller 130 and the mobile communication terminal 20 (S22). In addition, the service logic processing unit 141 checks whether any one of the subscriber of the mobile communication terminal and the subscriber of the called terminal is a subscriber of the call storage / transmission service of the present invention (S23), and if not, performs a general call processing (S24). ), If the service subscriber is a call after the call is started with the other terminal 21 (S25), the call content storage process 210 stores the call content (S26). When the call is terminated (S27), the contents of the call content storage process 210 is read out and converted into text (S28), and the email sending process 212 inserts the converted texts into a mail page of a specific form to the mail server 15. It transmits (S29). At this time, the contents of the call of voice can be simultaneously transmitted as an attached file.

In the above embodiment, the call between the mobile communication terminals 20 and 21 has been described, but the same may be applied to the case where the wired terminal 10 is made between the mobile communication terminals 20 and 21. In addition, the storage of the call content can be made only at the request of the caller or the called party. As in the embodiment, the case of the service subscriber can be searched so that the call content can be stored at all times. In addition, in order to reduce the communication load, the e-mail sending process 212 may be configured to transmit the e-mail to the mail server 15 only when the service subscriber sends a request for e-mail.

After the call is made, the call content is stored in the call storage process 210. When the call is terminated, the voice to text conversion process 211 reads the call content and extracts feature vectors of the voices. At this time, the feature vector of the contents of the call can be extracted by the caller and the called party (S32), by using the feature vector can be separated into the caller's voice and the caller's voice (S33). In this way, the text conversion is performed on the separated voice (S34). When the converted text is transmitted by e-mail, an identifier is added in time series so as to distinguish between caller's call content and caller's call content (S35). The e-mail sending process 212 is arranged in time series, creates a mail page to which an identifier is added, and transmits the data to the mail server 15 (S36 and S37). The subscriber of the mobile communication terminal 20 accesses the mail server 15 through the wireless Internet gateway 14 by the WAP, and downloads the mail page. The subscriber of the landline 10 connects to the mail server 15 and downloads the mail page.
