Description

How to make a call using a telephone domain and a system using the method {The calling method and system using telephone-domain}

The present invention relates to a phone number notation method, and more particularly, a phone number that is conventionally represented only by numbers, numbers, Korean alphabet, Korean letters, English letters, special characters and foreign characters having a size of 1 byte or 2 bytes (Hereinafter, referred to as 'telephone domain character') (hereinafter, referred to as 'telephone domain') to express the user's recognition easily and to a system capable of conducting a telephone call using such a method. It is about.

Currently used phone numbers are made up of a combination of numbers that have nothing to do with the person subscribed to the phone number, and the number of digits of these phone numbers is increasing with the increase in the number of subscribers. Therefore, there are currently 8 digits with long local phone numbers, and 11-digit phone numbers are also used daily if you attach an area code to it.

Telephone subscribers can select a number from the number that is not used by others depending on the region. Since most telephone numbers assigned in this way have nothing to do with the person or business with whom the telephone number is assigned, subscribers try to be assigned numbers that are easy for others to remember. In particular, this is especially true when opening a new business phone. In some cases, it is possible to devise ways to easily remember one's own phone number for publicity.

To reduce the inconvenience of changing phone numbers, KT operates a lifelong phone number system so that subscribers can continue to use the same number regardless of relocation. However, if the area code changes, these services cannot be used. .

As such, telephone numbers and their objects generally have little to do with remembering. Moreover, telephone numbers are simply combinations of numbers, and in addition, the number of digits is increasing, and as users expand their social activities, the number of times they search the phone book is increasing. In such a situation, it is very difficult and cumbersome to remember every single phone number consisting of numbers.

In addition, the current phone number may cause the subscriber to change the phone number inevitably, such as moving to another area code or changing the station number due to the circumstances of the telephone company. When the phone number is changed as described above, the phone number recorded on the business card and the promotional medium must be changed again and printed, and there is an inconvenience of providing the related people again.

An object of the present invention for solving the problems described above is to use the phone number by using the phone domain character notation, so that users can easily remember and can continue to use without alteration by external influences other than the user's will In providing a method.

Another object of the present invention is to provide a system capable of performing this method.

Telephone domain system using the telephone domain of the present invention for achieving the object as described above,

Search for receiver information using a terminal capable of inputting / receiving telephone domain characters and data received from the terminal, transmitting the search results to the sender terminal, and then sending the sender terminal to the receiver telephone corresponding to the retrieved receiver information. It includes a telephone exchange system.

The sender terminal refers to all communication means capable of making a telephone call. Basically, the sender terminal should be able to input and receive the above-mentioned telephone domain characters. The receiver telephone may include the function of the transmitter terminal as a communication means capable of talking to the transmitter. In addition, such a terminal can be broadly divided into a modem terminal (eg, a mobile communication terminal, a computer capable of telephone communication, etc.) and a non-modem terminal using DTMF tones or dial pulses.

Here, the modem terminal is a terminal capable of transmitting and receiving data by modulating and demodulating data. The function of the modulation and demodulation can be implemented using hardware (for example, a modem) or software.

Herein, a method of operating a telephone domain using each type of terminal will be described.

In the above-described method for operating a telephone domain using a non-modem type terminal, the sender terminal transcodes the telephone domain inputted to the sender terminal and sends it to the telephone switching center system, and the telephone switching center system receives it and restores it to the telephone domain. And retrieving the recipient information corresponding to the telephone domain, and transmitting the searched result to the sender terminal, and connecting the sender terminal and the receiver telephone corresponding to the receiver information if the search is successful.

In the above-described method of operating a telephone domain using a modem terminal, the sender terminal analogizes (modulates) the telephone domain inputted to the sender terminal and sends it to the telephone switching center system, and the telephone switching center system digitally receives the data received from the transmitter terminal. The method of restoring a telephone domain by processing (demodulating) is different from the above-described non-modem terminal.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the overall configuration of a system to which the present invention is applied.

The sender terminal 10 is a communication means for making a telephone call using a telephone domain, and in particular, a terminal capable of inputting a telephone domain character in a dialing mode.

The receiver telephone 20 includes all the communication means capable of talking with the sender by the above-described modem type telephone or non-modem telephone.

The telephone exchange station system 30 performs a general function performed by the telephone station, and furthermore, connects the sender terminal 10 and the receiver telephone 20 using the telephone domain according to the present invention.

The telephone exchange station system 30 according to the present invention analyzes the data received from the transmitter / receiver unit 31 and the transmitter terminal 10 that transmits / receives data to / from the sender terminal 10 and the receiver telephone 20 and responds thereto. And a control unit 32 for retrieving the recipient information, and a database 33 for storing and processing the recipient information corresponding to the telephone domain.

First embodiment

2 is a flowchart illustrating a process in which a transmitter terminal 10 and a receiver telephone 20, which are non-modem-type terminals of wired telephones, are connected using a telephone domain according to the present invention. At this time, the receiver telephone 20 may be a modem type or a non-modem type.

The sender inputs the telephone domain of the receiver to be called using the input means of the terminal 10 (step 201).

A domain code converter (not shown) in the terminal 10 converts the inputted telephone domain into a domain code and transmits it through a telephone line. The method of converting a telephone domain into a domain code is described in detail later.

In this case, the telephone domain is a new concept telephone number consisting of a combination of the above-mentioned telephone domain characters, and when one excludes the country code, one or more telephone domain characters other than numbers should be included. It should be easy to use using words and / or not duplicated. Such a telephone domain has a structure in which two or more characters are separated by one separator (for example, '.') Such as 'Hong Gil-dong.kr' and 'Patent Office.kr' (hereinafter referred to as 'two-layer structure'). In the case of a domain representing a person's name, there may be a person with the same name, and in the case of a business, a substructure is divided into two or more delimiters, that is, three levels to distinguish them. It is preferable to have a hierarchical structure beyond the structure. The delimiter '.' Is a hierarchical reserved control character that cannot be represented in pairs (eg '..') and must have at least one telephone domain character before and after. For example, Hong Gil-dong living in Daejeon is represented as 'Daejeon.Hong Gil-dong.kr' and Hong Gil-dong living in Seoul is labeled as 'Seoul.Hong Gil-dong.kr'. In the case of the Patent Office mentioned above, for example, the Patent Office. Registration Section.kr and the Patent Office.

The hierarchical structure of the telephone domain is not limited to the three hierarchical structure as in the above-described example, and can be displayed by increasing the number of hierarchies as necessary. The above example 'kr' is a country code reserved word designating a country, indicating the location of a database to search for a telephone domain, and forms the last part of the telephone domain. The country code may be omitted by the user. In this case, a country code previously designated by a domain code converter (not shown) in the terminal 10 is attached. The location of the country code is preferably at the end of the telephone domain, and may be located elsewhere depending on the communication regulations between the terminal 10 and the telephone switching center system 30. In addition, the country code is a reserved word of the telephone domain configuration, and may be used by combining not only 'kr' but other characters that match the image of the country. Business codes or promotional media may be omitted without the country code. In this case, the telephone domain may have a first hierarchical structure that does not include the separator '.'.

The domain code converter (not shown) of the sender terminal 10 converts each character of the input telephone domain into a code corresponding to the button of the sender terminal 10, and adds a button code indicating the type of the character to the telephone exchange station system. In step 30, the final code sent (hereinafter, referred to as 'domain code') is generated (step 202).

The principle of making the telephone domain code will be described. Digital signals that can be represented by a telephone connected to a regular telephone line without a modem are 12 tone signals corresponding to the numbers 0 to 9 and special symbols of # and *. Therefore, in expressing one character as a button code, one character cannot be represented by one button code except for any 12 specific characters and must be converted into a combination of two or more button codes. A button code is a logical meaning given by attaching numbers to each button signal.

This conversion process will be described in more detail.

Based on the general character code system, one Korean letter and one English letter have sizes of 2 bytes (16 bits) and 1 byte (8 bits), respectively, as shown in FIG. 3A. Figure 3a is a hexadecimal representation of the 'hong' and the ASCII code value 'A' in the commercial combination type.

In order to represent the combination of 12 telephone button codes, each character code value should be divided into 3 bit units. The reason for the division into 3 bit units is that the number that can be represented by 3 bits can be represented by one telephone button code regardless of the value from 0 to 7. In the case of 4 bits, numbers from 0 to 15 can be represented by any one of 12 telephone button codes from 0 to 11, but 12 to 15 require two button codes, so they are divided into a maximum of 3 bits.

FIG. 3B shows the code values of FIG. 3A in 3 bit units.

In the case of Korean, the most significant bit (MSB) is not needed, and the remaining bits can be divided into three bits and expressed as a total of five button code values.In the case of an English letter, eight bits are divided into three bits from the upper bits and the remaining two bits are two bits. As a single value.

Of course, this configuration can be changed. For example, in the case of an English letter, the lower bits may be distinguished by 3 bits, and the number of bits to be distinguished may be 2 bits or 1 bits instead of 3 bits. However, it is inefficient to make the bit division into two bits or one bit unit. In addition, in the case of a character having a code system represented by English letters, numbers, special characters, and 1 byte (hereinafter, referred to as '1 byte character'), all the necessary codes are defined by using a user defined code system rather than using the existing code system. The number of bits can be reduced. That is, when the number of characters used is 64 or less of the above single-byte characters, one single-byte character can be represented by two telephone buttons. In other words, if 64 codes are selected among 1 byte characters and code values are assigned from 0 to 63, the maximum code of one character becomes Ox3F, and each character is represented by only 6 bits. A button code can represent a single character. For Korean, you can use a custom code system, but this is not recommended because the number of phone button codes to be converted does not decrease.

The telephone button code thus constructed is continuously converted to a domain code by adding a control button code of '#' or '*'. This is for the controller 32 of the telephone exchange center system 30 to distinguish between the domain code and the actual telephone number code, and to restore the received domain code according to the character type. The actual phone number code is composed only of a number butt code that does not mix button codes such as '#' or '*', and is transmitted by a general telephone that directly enters a real phone number and makes a call.

Hereinafter, embodiments of the telephone domain will be described with reference to the accompanying drawings. When the telephone domain inputted to the sender terminal 10 is referred to as 'Seoul.ABC.Hong Gil-dong' as shown in FIG. 4, the hexadecimal Ox2CE1 (0010110011100001) corresponding to 'Seo' is 3 bits except the upper bit (MSB) When divided by the telephone button code, it is ' 2 (010) 6 (110) 3 (011) 4 (100) 1 (001)'. In addition, when the hexadecimal number Ox3689 (0011011010001001) corresponding to 'wool' is also divided into 3 bits and expressed as a telephone button code, it becomes ' 3 (011) 3 (011) 2 (010) 1 (001) 1 (001)'. In the case of English letters, a self-defined code system that can be represented by only 6 bits is used in order to be represented by only two phone button codes as described above, without using standard ASCII codes. This self-defined code system can be arbitrarily defined and used by the user. For convenience of explanation, the code values are sequentially assigned from 8 to A to Z. Therefore, the letter 'A' is the telephone button code '10' (the number of button codes is reduced to two compared with the case of FIG. 3B), and the 'B' is converted to '11' and 'C' to '12', respectively. do. Similarly, Hong Gil-dong's telephone button codes are '50667', '05651' and '12667', respectively.

To convert the converted phone button code into a domain code, first put the '#' button code meaning Hangul at the beginning, and then the phone button code '2634133211' in Seoul. Attach. The hierarchical separator '.' Is replaced with '*'. Next, since Korean characters are converted to English characters, add '#' button code, which means the conversion of characters, and then attach 'ABC' telephone button code '101112'. Subsequently, the second '*' button code is attached, and the characters are converted back to Korean, so the '#' button code is added, and 'hong gil dong' phone button code '506670565112667' is attached. In addition, the input phone domain 'Seoul.ABC.Hong Gil-dong' is omitted by the country code by the program, 'kr' as a reserved word is automatically added with the separator. When the telephone button code of 'kr' is calculated in the same manner as in the above example, the completed domain code is '# 2634133211 * # 101112 * # 506670565112667 * # 2231'. The sender terminal 10 receives the final code. A DTMF tone signal or dial pulse signal corresponding to each code value is generated and sent to the telephone switching center system 30 (step 203).

If the phone domain starts with an alphabetic character, '*' is added to the beginning of the domain code instead of '#'. The button code '*' has two meanings. When it comes first, it does not mean the hierarchical separator '.' But the subsequent character is an English character. The '#' button code also has two meanings. When it comes to the top, the next character is Korean and the middle one means the conversion of character type. The criteria to distinguish '#' button code and '*' button code at the beginning of domain code is to add '*' button code in the same way as for English characters when the first character is single byte character, and the first character is two byte character. In case of, add '#' button code as in the case of Korean. When the '#' or '*' button code is located at the top, it may indicate the type of character as described above, but at the same time, it may be a criterion for distinguishing the telephone domain code from the actual telephone number code. That is, when the first code received from the sender terminal is '#' or '*', the telephone exchange station system 30 recognizes and processes the received code as a telephone domain, and the first received code is a numeric button code. In the case of, it is treated as an actual telephone number entered directly by the sender.

The transmitting / receiving unit 31 of the telephone exchange station system 30 receives, from the sender terminal 10, the domain code instead of the actual telephone number in this example (step 204).

The control unit 32 codes the received data to restore the telephone domain from the received domain code (step 205), and separates the country code from the telephone domain (step 206). Code restoration refers to restoring the combined button code to the corresponding telephone domain character in the reverse order of the code conversion process in the transmitter terminal 10 described above. When separating country codes from telephone domains, the separator '.' Is also removed. That is, in this example, the telephone domain with the separated country code becomes 'Seoul.ABC.Hong Gil-dong'. The control unit 32 distinguishes whether the country code is domestic or foreign (step 207), and searches the domestic database 33a for the domestic domain (step 208). The foreign database 33b is searched (step 209) to obtain recipient information corresponding to the telephone domain. The recipient information includes the actual telephone number of the recipient. These databases 33a and 33b may be integrated and operated as one, but for efficient management, it is preferable to operate the distributed by region and country.

The retrieved recipient information is transmitted back to the corresponding sender terminal 10 (step 210), and at the same time confirming the search results (step 211), when the actual telephone number is obtained, the sender terminal 10 according to the existing conventional telephone exchange method (10). And the communication between the receiver telephone 20 (step 212). If there is no receiver information corresponding to the telephone domain, the telephone connection process is skipped and terminated.

The sender receives the search result in step 210 and confirms the search result by text on the voice guidance and / or the screen (step 213).

The sender checks the search result, i.e., the telephone number of the receiver, and decides whether to continue the telephone connection (step 214), so that if the caller wants to connect with the receiver, the caller does not hang up (step 215). If the recipient's phone number is not the desired area, that is, a long distance phone number, a mobile phone number or an international phone number may feel the burden of the phone bill, or may not want to make a phone call for other reasons. In this case, hang up the phone according to the normal method of using the telephone.

Of course, even when the telephone domain sent by the sender terminal 10 is not registered in the telephone exchange station system 30, a corresponding search result is transmitted to the sender terminal 10, in which case the telephone connection process is not performed.

In the above embodiment, the telephone exchange center system 30 omits a series of unnecessary processes in the following two cases and immediately connects with the receiver telephone 20.

In the first case, the received code is a real phone number code, not a domain code. It omits a series of steps to determine whether or not the search is successful (step 211). Connect with 20 (step 212).

In the second case, before checking the country code (step 207), it is determined whether the letters of the telephone domain in which the country code is separated are all numbers, and in such a case, it is treated as a real phone number to search below the country code judgment (step 207). The process of determining success or failure (step 211) is omitted and immediately connected with the receiver phone 20 of the corresponding phone number (step 212).

In addition, in the above embodiment, the telephone exchange center system 30 does not perform the connection with the receiver telephone 20 in the following two cases.

In the first case, the sender requests the telephone number search. In this case, steps 211 and 212 may not be performed. That is, when the sender enters the telephone domain, the sender can be informed of the telephone number corresponding to the telephone domain such as 114 service by adding a reserved character (eg, '@') at the beginning of the telephone domain.

When the code corresponding to the reserved character is detected, the control unit 32 searches for a telephone number corresponding to the telephone domain and transmits it to the sender terminal 10 and does not attempt to connect with the corresponding receiver telephone 20.

In the second case, when the sender does not know a part of the telephone domain, a specific reserved character (eg, '?') May be replaced by an unknown character position. In this case, the control unit 32 retrieves the recipient information by querying the phone domain characters other than the above reserved letter and transmits the corresponding recipient information to the sender terminal 10.

The database 33 of the telephone switching center system 30 may include the extension (premises) number as well as the actual telephone number of the recipient. This extension can be, for example, followed by the actual phone number. Or a delimiter such as '_'. When the extension includes the extension number in the searched telephone number, the controller 32 dials the actual telephone number of the receiver and connects the phone button signal corresponding to the extension number after a predetermined time, and then sequentially. It can be connected automatically to the extension number by generating. Alternatively, in order to reduce the load on the controller 32, the transmitter terminal 10 receiving the actual telephone number including the extension number may be programmed to perform the above function.

Second embodiment

The present embodiment is a case where the sender terminal 10 is a modem terminal, and the process of processing the telephone domain is different from that of the first embodiment.

The modem terminal can transmit the corresponding character code directly without converting the telephone domain into the telephone button code and the domain code as in the first embodiment. In order to make a call to the telephone domain by using the modem terminal, the sender terminal 10 should be able to enter a telephone domain character in a dialing mode, and if the send button (generally 'send' button) is pressed, the input telephone The domain should be able to be analogized (modulated) and transmitted to the telephone exchange system (base station) 30. However, before entering the modulation process, if it is omitted by checking the country code of the input telephone domain, it is automatically added by the program as in the first embodiment.

Telephone switching center system 30 digitally processes (demodulates) the received analog signal to obtain a telephone domain. The following process proceeds in the same manner as in the first embodiment described above.

Processes other than the difference in the above-described telephone domain processing process are the same as those in the first embodiment, and will not be described below.

As described above, the method of making a call using the telephone domain of the present invention enables people to easily recognize the telephone number and has the effect of minimizing the inconvenience caused by the telephone number change and connection.
