Description

How to handle characters using the phone button

The present invention relates to a character processing method for accessing an entire electronic exchange as a character using a telephone button to perform a desired special service.

The telephone button of the telephone is transmitted a number modulated with a multi frequency code (MFC) by pressing a button marked with a number. A typical electronic exchange device has a function of converting the modulated code into a number and switching the line according to the prefix data. The universal standard telephone button uses 10 buttons with numbers from 0 to 9 and 12 buttons including the * and # symbols.

There are certain characteristics of human memory ability. Psychology refers to memory as a stage of [coding - storage - retrieval]. According to Conrad's (1964) recall theory, there is a limit to the amount of information that can be stored in human memory in a short period of time. 7 ± 2 chunk: "The short-term memory capacity is about 7, which is forgotten after a duration of about 30 seconds or is forgotten by interference of other information".

Therefore, the current telephone number system has four chunks of information such as "081-042-485-7131" with the chunking of 13 information "0 8 1 0 4 2 4 8 5 7 1 3 1" Information was made easy to remember.

However, in the future of the information age, this will also be interrupted by infinite amount of information. Therefore, it is concluded that the text telephone numbers such as "Korea Communications Chungnam Headquarters" are easily memorized. The following table 1 shows how easy it is to memorize.

Existing phone number example Example of a new phone number 081-042-485-1234081-02-253-2345081-0431-222-7531081-051-651-4732081-053-676-6632081-064-931-1291081-062-712-9382081-0331-635-8450081- 0371-962-6329081-0651-321-1234 Korea Telecom Chungnam Headquarters Korea Telecom Seoul Headquarter Korea Telecom Chungbuk Headquarters Korea Telecom Busan Headquarters Korea Telecom Daegu Headquarters Korea Telecom Jeju Headquarters Korea Telecom Jeonnam Headquarters Korea Telecom Headquarters Korea Telecom Gangwon Headquarter Korea Telecom North Korea Headquarters

Therefore, if you change the current telephone number system, it will not work, but if you have a way to remedy the problem, you will be able to call anyone if you think of the destination you want to call.

Conventionally, character processing using a telephone button has been made of a non-rational system such as a word or password such as "012 character service ". Accordingly, there is a problem that it is difficult to express character information such as a computer keyboard with the telephone button of the telephone.

According to an aspect of the present invention, there is provided a character code synthesizing method, comprising: constructing a code table according to a character code synthesizing method so as to enable character processing; and inputting a character using a telephone button, , And the character processing system is intended to provide a character processing method for processing input characters as one sentence concept rather than a word concept.

According to another aspect of the present invention, there is provided a character processing method applied to a character processing system, the method comprising: when a digit is received according to a character processing request signal, opening a file storage unit, designating a reference field as a key code (kcode) A first step of searching data of a table (database), buffering search data, and then closing the file storage; A second step of repeating a process of sending an announcement broadcast until a desired subscriber is found, receiving a digit corresponding thereto, and searching for an additional code in a buffer, and guiding a vacancy if the target subscriber is not found; And a third step of outputting a number or a character according to the service type after the call is connected by selecting an output code when the desired subscriber is found, and releasing the call.

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

The present invention may be constructed as a standalone system, or may be used in a telephone exchange network, an intelligent network, or the like by being implanted in a whole electronic exchange apparatus.

1 is a configuration diagram of a telephone exchange network to which the present invention is applied.

Basically, there is a subscriber matching and trunk line matching function, and the minimum mode function is configured by expanding the existing number conversion function. In this case, however, a character code output routine is additionally provided along with the update of the processing process.

2 is a configuration diagram of an intelligent network to which the present invention is applied. In the figure, reference numeral 21 denotes an electronic exchanger, 22 denotes a common line signal network, 23 denotes a signal control system, 24 denotes an operation maintenance system, "25" represents a character processing system, "26" represents a database, and "27" represents a special service system.

The first and second electronic exchanges 1 and 2 correspond to a service switching point (SSP) of the currently operating intelligent network component and the common line No. 7 signal network 22 corresponds to a common line No. 7, Signal link. The character processing system 25 and the database 26 correspond to a service control point (SCP).

The operation and maintenance system 24 is a service management system (SMS) and the signal control system 23 is a signaling engineering administration system (SEAS). The special service system 27 including the special service provider, the multimedia system, and the database performs various services extended by using the character processing function of the present invention.

3 is an exemplary view of a character response to a telephone button;

The principle is as follows.

1. There is a character. The character is represented by any symbol.

2. The phone can not express a character.

3. However, phones represent symbols (numbers).

4. When you collect numbers, you become a symbol.

5. Symbols can be replaced with letters.

6. Process characters with your phone.

7. The symbol replaced by a letter is long.

8. Thus, the sentence is longer.

9. However, if a long sentence is processed, it may be shorter than the character.

The rules to collect according to these principles are as follows.

1. The number should be ## X. Here, 0 to 9 of X are replaced with numbers 0 to 9 in order.

2. English is set to ## XX. Here, XX is 01 to 26, and the letters A to Z are replaced in order.

3. Hangul is XXXXXXX. Here, XXXXXXX is a combination of digits and #, which is the maximum condition for expressing Hangul.

The rules of expressing Hangul are as follows.

(1) Arrangement of consonants

1-a, 2-a, ...., 9-i, 0-i

# 1- ㄲ, # 2- ㅋ, ...., 9- ㅉ, 0- ㅎ

(2) Array of vowels

1-, 2-ㅑ, ...., 9- ㅡ, 0- ㅣ

4. Composition of the sentence (key code: kCode) combines the characters (number) with the blank value of the characters plus the rms value.

In other words,

ㅎ ㄱ ㄴ = # 012 ____

ㄱ ㅜ ㄱ = 171____

ㅗ ㅇ = # 558 ____

# 012 + 171 ____ + # 558 ____ + 702 = # 012 ____ 171 ____ # 558____702, and when the space is removed, it is expressed as # 012 + 171 + # 558 + 702 = # 012171 # 558702.

4 is a conceptual diagram of a character processing process according to the present invention.

When a digit is received from the telephone 40 (41), it is retrieved 42 whether the first digit is a '*' digit. This routine is required in a mode that operates in parallel with the public telephone network. In other words, the ordinary telephone is a function added since the number is input from the beginning and the character processing is required, the division is required. Depending on the method of application according to the service, the symbol * may be replaced by specifying another service identification number.

If the first digit is not a '*' digit, it is a general call and therefore a general call processing routine is performed (43). In other words, it operates as a general exchange device. This routine is a routine for the case where the present invention is implanted in a general exchange and used in parallel with general call processing.

The process 44 having the number conversion function is a process having a function of comparing the input digit with the key code table of the file storage unit 47 and outputting the corresponding code or corresponding character of the matched data.

There may be a case where self termination is required depending on a service to which the present invention is applied. In the case of an unmanned guidance service or the like, a guide code is sent to the guide routine 46 so that voice guidance can be provided. If there is no matching key code in the number conversion process (44), the guide code passes the turn code to the guide routine, and ends after the guide.

The voice guidance module 46 guides the voice according to the guide code 45. [ The guide code 45 may be a telephone number corresponding to a name or a name, and the opposite function may be realized by designating the drive code of the voice guidance module 46 in the acode field to express it by voice You can have any code for it and apply it to the needs of the related higher processor.

The operation (code) file (kte1key.dat) of the file storage unit 47 has the following field configuration for one address.

- Keycode (kcode-key code)

- ncode-phone number

- The corresponding character (ccode-chr code)

- Additional code (tcode-extend code)

- Guide code (acod-anna_code)

- Output code (ocode-output_code)

The code converter 48 is a process for transmitting a corresponding character code. The maintenance process 49 has a database for storing codes corresponding to a single character, and is a utility for prefix operation through a terminal. The maintenance boss process 49 has a character-code file (key.dat) in the file storage unit 47 and has the following configuration.

- Single character code (C1)

- Keycode (K1)

The maintenance process 49 can be understood as a general database management concept, but the key code (Kcode) of the operation (code) file is analyzed / combined with the key code (K1) for the single character code (C1) It has the function to automatically configure, input / edit / delete (prefix) the value of each field and general statistical work.

The process of transmitting the number (PHONE NUMBER) of the input digits is as follows.

Example) Digit input: ㅎ (# 012171 # 558702)

Number output: 042-485-7131

This function can use the number conversion function of a general exchange by applying only some functions of the present invention as a routine to easily transfer the present invention to a general exchange. That is, the character code unit of the present invention occupies several digits, but since the reconstructed key code is operated in a compressed form, the existing device can be easily supplemented by software (S / W).

The process of transmitting the character code in which the input digit is code-converted is as follows.

Example) Digit input: ㅎ (# 012171 # 558702)

Character output: The interface is driven (typed) through the code converter 48 for Korean communication (corresponding character value).

Whether the number output or the character output is to be output depends on the application. That is, the number will be transmitted when it is connected to the general telephone network, and the character code will be outputted when it is a service accessing the multimedia device.

5A to 5C are flowcharts of a character processing method according to the present invention.

In a call waiting state, when the subscriber requests a call connection by matching with a local exchange at step 51, the local exchange sends a dial tone to the subscriber 52, and receives the call through an origination subscriber call process.

(54) When a local exchange or other provider requests a call connection from the local exchanger or TOLL exchange in the occupied waiting state of the trunk line, the toll exchange receives the trunk line occupancy request (55) and performs the incoming relay call processing (56).

Then, it is determined whether the first digit is the character processing request signal (*) (57). If it is not the character processing request signal, general call processing is performed (58) The character processing system 25 receives digits (59).

After receiving the first digit, the digit accepting module determines whether the next digit is a digit receiving end signal (*) or not (60) or requests additional digit accepting (61) from the digit receiving step (59) In the case of the digit reception end signal, the file storage unit 47 is opened with the collected digits, and the reference field is designated as the key code (kcode) (62). At this time, general processing items such as input delay or phasing are not mentioned during the digit processing.

Subsequently, the data of the operation code table (database) is searched to find the matching address of the digit value and the key code (kcode) (63) to form an array of the number of addresses corresponding to each other, and the key code buffer (aKcode) A key code (Kcode) corresponding to the buffer (aNcode), an output code buffer a0code, an additional code buffer Tcode, a character code buffer aCcode, a guide code buffer aAcode, The additional code Tcode, the character code Ccode, and the guide code value are buffered 64, respectively. Thereafter, the file storage unit 47 is closed (65).

Thereafter, the number of array elements (N = number of subscribers with duplicated numbers) is counted and it is determined whether the number is zero (no search data) (66). If it is 0, that is, if there is no search data, 67). If there is search data, it is judged that the number of array elements is 1 (one search data). If the search data is 1, that is, if the search data is 1, Jump, and if it is not 1, it is a plurality of subscribers, and therefore, a process of finding one of the target subscribers is performed (69-77). At this time, although it is impossible as a current telephone system, there is a high possibility that a plurality of subscribers of the same number exist in an intelligent service that performs character processing. Therefore, at this time, the voice guidance (query response format) is performed with the guide code among the data in the buffer and the next digit is accepted. At this time, even when the voice guidance is in progress, the corresponding digit is input. Upon reception of the digit accept routine end signal (delemiter: . The digits are compared in the additional code to finally find one destination.

That is, after the number of repetitions K, the number of digits D, and the number of guide codes A are set and the reference code is set to the additional code TCODE (69) (70) If the number of repetition times is larger than the number of guide codes, it is determined that a desired value is not found so that the guide code is completely output. If the number of repetition times is less than the guide code number And the voice guidance according to the guide code acade is performed (71). Here, the guide code is processed in the order specified in the guide code field (acode), which is output first in the order of the first guide code, and in the next routine, in the order of the second guide code (A ++). A ++ means that this guide code has already been exited, so we will prepare the following guide code.

Thereafter, it is determined whether the digit acceptance routine end signal (the end signal of the digit acceptance routine due to the lapse of time or the enter input signal of the user) is received (72) If the signal is not a routine end signal, the value added to the input digit is held as a D value (D ++) (74), and the process is repeated from the variable setting process (69) (TCODE) among the data stored in the memory 64 and searches for one of the matched data (75).

If the number of array elements is 1 (the number of pieces of search data is 1), it is determined (76). If not 1, (69). If it is 1, that is, if the search data is one, the output code is determined since the target subscriber is found (78). The output code (0CODE) is data that prefixes the output direction, that is, the type of trunk to be connected to each service.

In accordance with the output code, various 700 type services 81, an intelligent network connection service 82, a character recognition service 82, and a character recognition service 82 operated by the character recognition unattended service 114, the character recognition unattended service 114, The special service 83 and the general subscriber representative number 84. After the occupancy of the character recognition service call is monitored 86, the call is released and the call is terminated 87, .

In the concept that the intelligent network connection service 82 uses a service such as 080 and also a general subscriber needs to know the number, the subscriber who is treated as a character, that is, a subscriber who wishes to use the 080 service of "00 aviation", does not know 080-1234 Calling your subscriber's character "00 Airlines" will be called up and you will be able to use the service according to the guide code by patching the code to 080-1234.

The character recognition special service 83 may be a special service in the reality that the character recognition service is regarded as a special service. However, in order to listen to voice data by calling other processes such as the Internet, etc., Will be possible.

The general subscriber representative number 84 is a case in which the private equipment is fetched or the final destination is pushed in response to the corresponding private equipment even when the subscriber private equipment (DID) is installed.

6 is a structural diagram of a character-code table according to the present invention.

The character-code table is composed of a code table 61 of maximum 7 bytes and a character table 62 of 2 bytes.

The code table 61 is a code block obtained by sequentially adding corresponding numerals based on the stroke order of the corresponding characters by the button arrangement shown in Fig. The character table 62 is a table in which 10 digits from 0 to 9, 25 alphabets from A to Z, and 98% or more of 2350 Korean characters in the KS standard are input.

The key code table is the key code (kcode) of the prefix data (kteldat.dat) file to be actually operated, and analyzes the input of the character code (ccode) of the operator at the prefix of the electronic exchanger, It is a key code that is searched, and the correspondence code (code table) is read to remove whitespace, and is automatically combined in order.

The rules for constructing the character-code table are the same as the rules for collecting described in FIG. 3 and will be described in detail as follows.

1. Numbers 0 through 9 should be ## + numbers.

That is, 0 is ## 0, 1 is ## 1, and 9 is ## 9.

2. Let's have 26 characters from alphabet A to Z as ## 01 ,,, ## 26.

That is, A is ## 01, B is ## 02 ,,,, and Z is ## 26.

3. Hangul character 2350 is a collection of numbers XXXXXXX.

That is, when the button is pressed in accordance with the stroke order of the Hangul, it becomes a column that lists them in order.

Here, the rules for arranging consonants and vowels are as follows.

- arrangement of consonants

# 2, # = 5, # 2, # 3, # 4, # 5, # 6, # 7, # 8, # 9, # = 8, # = 0, # = 1, # = 3, # = 6, # = 7

- array of vowels

= 1, ㅑ = 2, ㅓ = 3, ㅕ = 4, ㅗ = 5, ㅛ = 6, ㅜ = 7, ㅠ = 8, ㅡ = 9, ㅣ = 0

The other pair vowels are represented by a combination of short vowels.

In other words, ㅐ is expressed as a + ㅣ, and ㅢ is represented as ㅣ + ㅣ.

On the other hand, the structure of the sentence (key code: kCode) is the same as that described in Fig. 3, so that further explanation is omitted.

7 is a structural diagram of an operation code table according to the present invention.

The operation code table file has the following definition. Is a data file stored in the file storage unit (47) of the electronic exchanger and containing a prefix to be used for subscriber call processing. The number of records corresponds to the number of subscribers according to the number system, and the length of each field may be different depending on the restriction range of the number of digits according to the service to be permitted and the kind to be guided. Such an operation code table includes a key code field, a corresponding number field, a character code field, a guidance code field, and an additional code field.

The keycode (kcode-key code) is a value of the data retrieval key for the input digit, and primarily matches the matched value of the digit and the keycode. The key code is automatically configured by analyzing the character code input value during the prefix operation as described in FIG.

The corresponding number (ncode-phone number) can be variously changed according to the service type of the telephone number type to be outputted to the output side of the key code input. For example, in a prefix having an area code as an output code, a prefix having a prefix of a local station and a subscriber number will be provided. In the case of a prefix between subscribers in a city, only a subscriber number can have four digits.

The character code (ccode-chr code) is a character to be sent through a separate interface when the output code is prefixed to send the corresponding character. In maintenance, the character string corresponds to the subscriber name, service name, and the like. This string is converted to a key code. In the use mode, the key code must be changed and operated through the conversion processor.

The additional code (tcode-extend code) is a code added to the key code, and a general term is a keyword. This may be an additional key code for comparing and retrieving digits that are additionally collected according to the voice guidance among the data classified by the key code.

The code (acode-anna_code) is a field containing a code to be sent to the voice guidance apparatus, which is not necessary in a system derived in accordance with a uniform procedure, and is necessary for a flexible system configuration. If guidance is given in the form of the name of the trial, the name of the village, and the name of the village, it is structured so that it can be flexibly handled with a guide code indicating how to give the name of the headquarters, local name and department name.

The output code (ocode-output_code) is data that prefixes the type of trunk to be connected for each service. Therefore, the value of the output code can be flexibly applied according to the type of communication service, and the value is a service identification code or character data.

An example of the configuration of the first operation code table is as follows.

Record 1

- Character code: Korea Telecom

- Keycode: # 012171 # 558702

- Corresponding number: 485-7131

- Information Code: Local Headquarters, Country, Department Name: Code

- Additional code: Chungnam Headquarters, Planning and Administration Bureau, Management Improvement Department: Applicable code

- Output code: 042

Record 2

- Character code: Korea Telecom

- Keycode: # 012171 # 558702

- Corresponding number: 255-7131

- Information Code: Local Headquarters, Country, Department Name: Code

- Additional code: Chungnam Headquarters, Planning and Administration Bureau, Management Improvement Department: Applicable code

- Output code: 02

When there are 2 subscribers as above by searching by key code by subscriber's call, the first announcement code informs "Enter the name of the regional headquarters", the subscriber inputs "Chungnam headquarters" If it is "Chungnam headquarters", it becomes record 1. Therefore, the output code of record # 1 is 042, so it is patched to 042 trunk, and it is connected to 485 station 7131 from the toll exchanger of charge.

An example of the configuration of the second operation code table is as follows.

Prefix 1

- Character code: Weather information

- Keycode: 1071893865

- Corresponding number: 2030

- Information Code:

- Additional code:

- Output code: 700

Prefix 2

- Character code: Korean Air

- Keycode: 310 # 018158

- Corresponding number: 255-1234

- Information Code:

- Additional code:

- Output code: 080

The second example above is an example of a character recognition system patching an existing special service network. Subscribers do not need to consult the special information guide or 114 to use the weather service or 080 service for Korean Air. Here, it is not necessary to separately prefix the guide code and the additional code. The system also does not need to run non-prefixed routines.

A third example of the configuration of the operation code table is as follows.

Prefix 1

- Character code: 700

- Keycode: 700

- Corresponding number: 2030

- Information Code: Information Name: Applicable Code

- Additional code: 1071893865: Weather information code

- Output code: 700

Prefix 2

- Character code: 080

- Keycode: 080

- Corresponding number: 255-1234

- Code: Business Name: Code

- Additional code: 310 # 018158: Korean Air Code

- Output code: 080

The third example above is an example of a case where a character recognition system patches an existing special service with voice guidance. Subscribers do not need to contact Special Information Guide or 114 to use the weather service or 080 service for Korean Air. In this case, the character processing system must have an identification code that distinguishes it from the existing intelligent network.

FIG. 8 is a flowchart of a maintenance method according to the present invention. Only the flow of the key code configuration is shown except for the general data management function.

First, a buffer mode is designated and a character 81 is input (82).

Since this process is performed at the operating terminal, the end of input is an enter or return key, and it is checked whether the value of the last key is an end signal 83. If not, (85), and if it is a termination signal, the number of characters is calculated (85). At this time, alphabets and numbers in the number of inputted characters are one byte because they are less than ASCII code 128, and Hangul is 2 bytes in the standard KS standard.

Then, it is determined whether the inputted number of characters N is 1 or a letter or a numeral (86). Otherwise, 1 byte is added to 2 bytes because it is a Korean character. After character determination, a character-key code table is opened (88), a loop is formed by the number of input characters (N), and the data buffer (D) and the number of repetitions (K) are set (89). Thereafter, the key code is extracted from the character-key code table by one character according to the value of the data buffer (D), and the key code value is obtained (90). If it is determined that all characters have been processed (91), the repetition number is incremented by 1 and the process is repeated from the variable setting process (89). If all characters have been processed, the operation code table is opened and the buffer value (D) Configure and close each table (93).

The work up to now is a flowchart for configuring only the key code in the prefix operation, and other field operations of various operation code tables are similar to general database management, so the description is omitted.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.

The present invention as described above does not require reinvestment such as correcting only the software (S / W) to be applied according to the service classification code and adding the hardware (H / W) It is possible to perform various kinds of services according to the method of prefixing the additional code (tcode) and the output code (ocode). By supplementing some functions of the existing electronic exchanger in spread application, And it can be easily applied to existing intelligent network services. Therefore, it is possible to construct a character processing type intelligent network economically, and it is possible to process characters by expressing Korean characters of the KS standard more than 98% in character expressions.

In the case of a digit end signal, the file storage unit is opened with the digits collected, (kcode); And The data of the operation code table (database) is searched to find matching addresses among the digit value and the key code (kcode) to form an array of the number of addresses corresponding to the keycode (aKcode), the number code buffer (aNcode) A key code (Kcode), a number code (ncode), and an output code (0code) of the corresponding address in the output code buffer a0code, the additional code buffer Tcode, the character code buffer aCcode, And closing the file storage after buffering the additional code (Tcode), the character code (Ccode), and the guide code (Acode), respectively. 5. The method of claim 4, The second step comprises: A fourth step of judging whether there is search data by counting the number of array elements, and if there is no search data, terminating after the absence guidance; And As a result of the determination in the fourth step, if the search data is one, the target subscriber is found and the transition to the third step is performed. If the search data is not one, the subscriber is a plurality of subscribers. And a fifth step of receiving a digit receiving routine end signal (delimiter: *) by receiving the next digit and searching for an additional code in the buffer to find the desired subscriber. 6. The method of claim 5, In the fifth step, After setting the number of repetitions K, the number of digits D and the number of guide codes A and setting the reference code as an additional code TCODE, it is determined whether the number of repetitions K is greater than the number of guide codes A A sixth step of judging; If it is determined that the number of repetition is greater than the number of guide codes, it is determined that a desired value is not found so that the guide code is output as it is. A seventh step of judging whether the signal is a digit accepting routine end signal by accepting a digit inputted by a user and giving a voice guidance in the order; As a result of the seventh step, if it is not the end signal of the digit accepting routine, the process continues from the sixth step after holding (D + +) the input digit value D as the input digit number D Searching for a buffer and searching for an additional code (TCODE) among the data held in the third step; And It is determined whether the search data is 1 or not. If the search data is not 1, the process repeats the process from the sixth process after holding the value (K + +) once more to the value (K) And a ninth step of using the telephone number as an intended subscriber. 6. The method of claim 5, In the third step, A sixth step of determining an output code which is a prefixed data type of a trunk to be connected per service; In response to the determination result of the sixth process, various 700 type services operated by a character recognition unattended service 114, a character recognition unattended 114 access service, a general van (VAN) service provider, an IN service, a character recognition special service, A seventh step of connecting the call to the representative number; And And monitoring the occupation of the call and releasing the call when the occupation ends, and terminating the call.
