BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal, and more particularly, to a technique of indexing a recording file in which call contents are recorded.

The mobile communication terminal provides a call recording function to record the contents of a call during a call. The call recording feature allows the user to record the call and, if necessary, find and listen to the desired recording file. However, if there are a large number of recording files, the user cannot distinguish which recording files are with whom. Since the recording file names are normally numbered in the order of recording, such as 001 and 002, it is not easy to find a desired recording file, and it is inconvenient to select and listen one by one.

An object of the present invention is to provide a method for indexing a recording file for each call counterpart.

According to an aspect of the present invention, a call recording file indexing method executable in a mobile communication terminal according to an aspect of the present invention reflects call counterpart information in a recording file generated by recording a call and stores the call counterpart information in a memory. By referring to the recording files stored in the memory, a list is provided.

According to this aspect of the present invention, the mobile communication terminal according to the present invention enables indexing of a recorded file with call counterpart information, so that the user can easily determine to whom the respective recorded files provided in the list are to whom. You can easily find the recording you want.

The foregoing and further aspects of the present invention will become more apparent through the preferred embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention.

1 is a block diagram schematically showing the configuration of a mobile communication terminal according to the present invention. As shown, the mobile communication terminal basically includes a keypad 100, a display unit 200 for displaying a menu and an operation state, and a wireless communication unit 300 for extracting a voice and data signal from a radio signal transmitted and received through an antenna. ), A voice input / output circuit 400 for inputting and outputting a voice call signal from the wireless communication unit 300 through a microphone and a speaker, and a memory 500 for storing control program data for controlling overall operations of the mobile communication terminal. And a conventional mobile communication terminal such as the control unit 600 for controlling the entire system.

First, the keypad 100 and the display unit 200 which is a liquid crystal display device may have a conventional well-known configuration. The memory 500 is divided into a ROM region in which control program data for controlling an operation of a terminal is stored, and a RAM region in which data generated during a terminal control operation are temporarily stored. In addition, the phone book database 530 is stored in the ROM area. As is known, the phone book database 530 includes fields such as a name, a phone number (mobile phone), a home phone number, and a company phone number for each record.

The wireless communication unit 300 is configured to include an antenna and RF circuit for cellular communication with the base station. The voice input / output circuit 400 is a well-known configuration that processes digital voice data into an analog voice signal or vice versa, and includes an additional circuit such as an audio amplification circuit or a filter. The baseband circuit of the wireless communication unit 300 and most of the circuits of the control unit 600 are commercially provided as a single integrated circuit. This integrated circuit, commonly referred to as an MSM chip, includes internally dedicated hardware for processing communications, a digital signal processor and a general purpose microprocessor. Each part constituting the control unit 600 may be configured by dedicated hardware or software or a mixture thereof.

A mobile communication terminal having such a conventional configuration can provide a call recording function as is known. Hereinafter, a brief description will be made of a method for recording a call. First, during the call, the received voice inputted through the microphone and amplified by the voice input / output circuit 400 and the received voice received through the wireless communication unit 300 and converted into analog voice by the voice input / output circuit 400 are synthesized. The synthesized analog voice signal is converted into a digital compression code and compressed (for example, in the form of a .MMF file), and the compressed data is stored in the memory 500. Through such a series of processes, voices transmitted and received during a call may be recorded, and since the recording technology itself is obvious, a detailed description thereof will be omitted below.

2A is a flowchart illustrating a method of generating a call recording file. The user commands a call recording through key manipulation during a call. The control unit 600 confirms that there is a recording command from the user (step S200) and, according to an embodiment, checks whether the other party's telephone number, which is the call counterpart information, is stored in the phonebook database 530 (step S210). In the case of incoming calls, the other party's telephone number is obtained by the Caller IDentification (CID) function as is known. On the contrary, in the case of call origination, since the counterpart phone number is directly input from the keypad 100 or selected from the phonebook database 530, the controller 600 can know the counterpart phone number.

If the other party's phone number is not stored in the phonebook database 530, the controller 600 records the call voice according to the known technical method as described above to generate a recording file, but reflects the other party's phone number in the recording file ( Step S220). Reflecting the other party's phone number in the recording file may be recording the other party's phone number in the phone number field defined in addition to the recording file. According to an example, the file name is named 'No name_1', and the subsequent sequence is continuously increased to generate a recording file to distinguish the recording file.

If the other party's phone number is stored in the phone book database 530, the control unit 600 generates a recording file by recording the voice of the call, but reflects the other party's phone number and the other party's name, which is the other party's information, in the recording file (step S230). . In this embodiment, the control unit 600 records the other party's phone number in the phone number field further defined in the recording file, and the other party is recorded in the name field on the same record as the other party's phone number stored in the phonebook database 530. Include the name in the file name of the recording file. According to an example, the file name is named 'Hong Gil-Dong_1', and the subsequent sequence is further increased to generate the recording file for the call with Hong-Gil-Dong to distinguish the recording files.

Thereafter, when a recording end command according to a user's key operation occurs or a call ends (step S240), the controller 600 ends recording and stores the recorded file in the memory 500 (step S250).

2B is a flowchart illustrating a method of providing a call recording file. The user requests a list of call recording files by selecting a menu in which call recording files are stored through key manipulation. The controller 600 confirms the call recording file list request from the user (step S300), and presents various search conditions according to an embodiment (step S310). The search conditions may be ① by date, ② by phone number, ③ by name, and ④ by direct search.

The user selects a desired search condition among the presented search conditions. ① When selecting by date, the control unit 600 searches the date field of the recording file stored in the memory 500, and displays the list of recorded files sorted in the order of date on the display unit 200 screen ( Step S320). ② By selecting the telephone number, the control unit 600 searches the telephone number field of the recording file stored in the memory 500 and displays the list of recorded files sorted in the order of the telephone numbers with the highest number on the display unit 200. (Step S330).

If selecting by name, the control unit 600 searches the file names of the recorded files stored in the memory 500 and displays the list of recorded files sorted in the order of the file names on the display unit 200 screen (step S340). According to another embodiment, a folder is created for each file name having the same name, and a list of recorded files having the file name with the same name is provided in each generated folder. That is, it is classified into Hong Gil-dong folder, Kim Gap-soon folder, and Sam Soon folder, and the list of recorded files having file names including each name under the folder is classified. Such a method of providing a classification of each call counterpart and a list of recording files corresponding to each classification subordinate may be applied to ② by phone number.

④ If the direct search is selected, the controller 600 requests input of part or all of the file name according to an example. When the user inputs the other party's name through key manipulation, the controller 600 searches the memory 500 for the file name having the input name and displays the searched recording file list on the display unit 200 screen (step S350). ).

The user can select a desired recording file from the provided list. In particular, when the file name includes the other party's name, the user can easily find the desired recording file. When the user selects a desired recording file and plays a command, the control unit 600 reads and plays the selected recording file from the memory 500. When the call connection command is made, the control unit 600 stores the selected recording file as a phone number stored in the telephone number field of the selected recording file. A call connection is attempted (step S360) (step S370). According to an example, the user may make a call connection command by pressing a call key on the layout screen except play for playing the selected recording file. Therefore, when you want to call the other party after listening to the recording file, you can go directly to the phone book screen to find the phone number or go to the idle screen (idle), you can try to connect the call immediately.

In addition, when the other party's telephone number recorded in the telephone number field of the recording file is stored in the phone book database 530, the recording file may be selected to enable the phone book search.

As described above, the method for indexing a call recording file executable in the mobile communication terminal according to the present invention enables indexing of a recording file with call counterpart information. It's easy to find out whether or not you're looking for an easy way to find the recording you want.

In addition, the present invention when you want to call the other party after listening to the recording file to go to the phone book screen to find the phone number or go to the idle screen (idle), without having to enter the phone number, try to call immediately Make it possible.

On the other hand, the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
