In describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the description thereof will be omitted.

1 is a schematic configuration diagram of a telephone number search system of a remote terminal according to the present invention, and FIG. 2 is a flowchart illustrating an embodiment of a telephone number search method of a remote terminal according to the present invention.

As shown in FIG. 1, the system of the present invention is roughly composed of a user terminal 10, an exchange station 20, a remote terminal 30, and a counterpart terminal 40. As shown in FIG.

The user terminal 10 includes both a wired terminal connected to a public telephone network and a wireless terminal connected to a mobile communication switching station as a terminal that a user can use at a current location.

Switching station 20 is a mobile communication switching station, and controls the signal transmitted / received from the user terminal 10 to the remote terminal 30, and supports call origination to the retrieved telephone number.

In particular, when the user terminal 10 is a wired terminal, the signal transmitted from the user terminal 10 is transmitted to the switching center 20, and when the retrieved telephone number is a wired terminal, call connection with the remote terminal 30 is performed. A public switched telephone network switching station is further included, which specifies that it is not shown in FIG.

The remote terminal 30 is a terminal that stores a phone number to be searched by the user. The remote terminal 30 is located at a long distance from the user, and thus the user cannot directly operate the key input unit.

Currently, a wireless mobile terminal represents the remote terminal 30, but the remote terminal 30 may be a wired terminal having a phone number storage function.

The counterpart terminal 40 is a terminal to which a phone number retrieved from the remote terminal 30 is assigned, and includes a wired or wireless terminal. When the user requests to make a call to the retrieved phone number, the counterpart is connected to the user terminal 10. The terminal is connected to support the user to talk to the user of the counterpart terminal 40.

A process for searching for a phone number stored in the remote terminal 30 in the system having the above configuration will be described in detail with reference to FIG. 2.

In order for the user to retrieve the telephone number stored in the remote terminal 30, the service identification number and the number of the remote terminal 30 are input using the user terminal 10 available at the user's current location (see FIG. S10).

The service identification number is information known to the user by a predefined number for searching a telephone number.

When the power of the remote terminal 30 input in step S10 is turned on (S20), a warning sound indicating that the telephone number can be searched is output. The password of the remote terminal 30 is input according to the warning sound output (S30).

If the password entered in step S30 matches the password of the remote terminal 30 (S40), a message for inputting search information to be searched is output.

If the input password does not match, a warning message is output (S85).

The search information is specifically the name of the counterpart.

The search information includes a number corresponding to each letter of the alphabet, a delimiter for distinguishing each letter, and a termination identifier for notifying the termination of search information input.

One embodiment of a table table in which numbers correspond to each letter of the alphabet is shown below.

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z One 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

As the numbers correspond to each letter of the alphabet as described above, the user can enter the alphabet corresponding to the name of the counterpart as a number.

The table table as described above may be known or carried by the user in advance.

In this case, delimiters such as * and # are included between the characters to distinguish between the characters.

For example, if the user's name is 'BRIAN', the user may input '2 # (delimiter) 18 # 9 # 1 # 14 * (terminator)' as the search information.

When the search information is input (S50) and transmitted to the remote terminal 30, the telephone number search unit (not shown) of the remote terminal 30 converts the search information into a character stored in the telephone number. In step S60, the phone book searches for the name of the other party.

That is, the telephone number search unit converts the received number of search information into an English alphabet according to the table shown in Table 1 above.

In particular, when the other party's name stored in the phone book is input in 'Hangul', a function for converting the English name inputted into Korean according to the above table should be further included in the phone number search unit.

If the other party's name according to the search information exists in the phone book (S70), the call originator of the remote terminal 30 attempts to make a call by requesting a call to the retrieved phone number (S80).

More than one phone number may be stored in the searched party's name. In this case, a call is attempted to a mobile terminal which is commonly used.

When the call is directly sent to the searched phone number, it is convenient because the user can make a call to the other party's phone number without memorizing or memorizing the searched phone number separately.

In the embodiment of FIG. 2, the call is attempted to be sent to the searched phone number immediately after the user searches for the phone number. However, the call is not immediately attempted to the searched phone number. It may be output to the user terminal 10 via 20).

The switching center 20 outputs a message to the user terminal 10 that allows the user terminal 10 to select whether to request a call to the telephone number before outputting the searched phone number to the user terminal 10.

When a signal for requesting a call origination is input from the user terminal 10 to the phone number, the call request is made to the phone number.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, the present invention not only can search the other party's phone number stored in a terminal located in a remote location that the user can not directly operate, but also the call to the other party's phone number because the call is attempted The convenience is that you can talk to the other party without pressing the number.

In particular, it is possible to use a variety of types of terminals, such as wired or wireless for the search of the phone number of the terminal in the remote location, it is convenient to search the phone number of the remote terminal anywhere.
