DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device for selecting and transmitting one of lines provided by a plurality of communication carriers, a communication method for the device, and a computer storing a control program for the device. It relates to a readable recording medium.

[0002]

2. Description of the Related Art Conventionally, there is known a technique in which one line is selected and used from line services provided by a plurality of telecommunications carriers. For example, LCR (Least Cost Routing)
In the case of, a line having the lowest charge is selected using a database composed of a plurality of pieces of information such as a communication time zone and a communication charge (including late-night discount service information and the like). That is,
Based on the input telephone number, the above database (table) is searched, an access code corresponding to the line of the cheapest communication carrier is obtained, and used for a final call from the input telephone number and access code. The telephone number is determined.

[0003] The LCR method is an LC provided by a telecommunications carrier.
In addition to the implementation in the form of an R adapter and the like, the implementation in a communication device such as a telephone or a facsimile device is also known.

[0004] Further, a communication time zone serving as a reference for line selection,
Data including a plurality of information such as communication charges (including late-night discount service information) (hereinafter referred to as line selection information) needs to be changed in the case of a charge change or relocation, but this line selection information is updated. As a method, a technique of downloading data using a DTMF signal is known.

In particular, there is a need for a data configuration of line selection information and a configuration for the process that can easily execute the telephone number conversion process itself even if the process related to the time zone is omitted.

Further, when the line selection technology is implemented in a communication device such as a facsimile machine, it is often difficult to secure a memory area for storing various information for selecting a line. Also from this viewpoint, it is desirable that the data structure of the line selection information is simpler and does not require a large storage capacity.

[0008] In addition, the download of the line selection information is performed by DT.
When using MF signals, communication devices such as facsimile devices need to add special processing for DTMF detection, which is originally unnecessary, or attach an external LCR adapter. There is a need for a configuration that allows easy and inexpensive downloading.

[0009] In addition, if the user moves to another area due to relocation or the like, the line selection information needs to be updated, and until the line selection information is updated, an expensive communication fee may be charged. Since the communication device cannot be used until the information is rewritten when the device is relocated, a technique for easily updating the line selection information is desired.

An object of the present invention is to solve the above-mentioned problems and to provide a line selection technique which can be implemented by a simple and inexpensive hardware and software in a communication apparatus such as a facsimile apparatus and is easy to handle.

It was adopted configuration.

Alternatively, a configuration is employed in which a regular expression is used as a detection number corresponding to a telephone number to be converted into an access code of a communication carrier in the detection table.

[0013] Alternatively, the external line calling number to be removed in the comparison and conversion of the telephone number is stored in the external line calling number storage means, and the external telephone call in the external line calling number storing means is stored in the input telephone number. Detecting whether a number has been added or not, and if an outside line calling number has been added, remove the outside line calling number from the input telephone number, compare the telephone number and convert the telephone number, A configuration is employed in which the removed outside line calling number is added to the converted telephone number and then used for calling.

Alternatively, the line selection information to be stored in the line selection information storage means or the external line calling number in the external line calling number storage means is received by using a facsimile communication procedure.

[0015] Alternatively, when receiving line selection information or an outside line calling number using a facsimile communication procedure,
A configuration is adopted in which update date and time data for validating the line selection information or the outside line calling number is received, and the date and time for which the received line selection information or the outside line calling number should be validated is determined based on the received update time data.

[0016] Alternatively, a configuration is employed in which the line selection information in the line selection information storage unit is changed by receiving a command to change the line selection information in the line selection information storage unit using a facsimile communication procedure. .

FIG. 3 shows a flow of processing from input of a telephone number to connection to a line of the communication apparatus according to the present invention. The processing in FIG. 3 corresponds to the telephone number input control step to the call control step in the ROM 26 in FIG.

In step S301 of FIG.
The telephone number input by the ten-key or one-touch key 2 is stored in the dial buffer (27g in FIG. 2). Storing in the dial buffer is performed when a call instruction (such as pressing the start key of the input device 22) is made after the input of the telephone number.

In step S306, if there is a detection table (27a in FIG. 2) for telephone number conversion,
The process proceeds to step S305, and if not, the process proceeds to step S305.

In step S302, the telephone number conversion operation SW (27c) performs a telephone number conversion operation (S30).
If W = 1) is set, step S303
The area code or the communication carrier access number described in the detection table is detected from the first digit of the telephone number (dial data) input in step (1).

That is, only when the detection table (27a) exists and the telephone number conversion operation SW (27c) is set to perform the telephone number conversion operation (SW = 1), the telephone numbers in steps S303 and S304 are set. Execute detection and conversion processing.

Then, in step S304, a conversion process is performed on the telephone number of the dial data based on a conversion instruction command (described later) described in the detection table (addition, exchange, deletion, Retention, etc.).

In step S302, the telephone number conversion operation SW (27c) does not perform the telephone number conversion operation (SW
= 0), the conversion process of the telephone number of the dial data is not performed.

In step S305, dial data is transmitted to the line using the input telephone number or the converted telephone number.

4 to 6 show steps S303 and S303.
FIG. 3 shows the telephone number detection and conversion processing 304 in detail.

First, FIG. 4 shows a configuration of the detection table 27a and the access code table 27b as line selection information. The “number” on the left side of “:” in the detection table 27a and the access code table 27b in FIG. 4 is an index (may be considered as an address) of the table (not the content of each table).

The detection table 27a includes (1) a detection number, (2)
It is composed of a plurality of tables (64 in FIG. 4, 0 to 63) each consisting of a conversion instruction command and (3) an access table number.

For example, the fifth line (index 05 :)
Table content "001C1" is "0" as the detection number.
01 "," C "as a conversion instruction command, and" 1 "as an access table number. However, there may be a case in which there is no access table number part. For example, the table content “01A0K” in the second row (index 02 :) is “01A0” as the detection number.
Is included as a conversion instruction command (see the following description).

Next, (1) a detection number, (2) a conversion instruction command,
(3) The access table number will be described.

First, the detection number is a numeral for detecting a number such as an area code and a communication carrier access code. In the present embodiment, a character code ("0"-"9") representing a normal telephone number is used. , "#", "*") And a character string of up to six digits, which can include metacharacters (so-called regular expressions) of "A" or "E" in addition to these characters.

First, the metacharacter "A" matches one digit of all telephone numbers (that is, "0"-"9", "#",
Matches any of "*"). For example, “01A0” matches “0190”, “0110”, and “01 # 0”.

The metacharacter "E" is a specific number ("0"-"9", "#", "*") registered at the same digit position in all other detection tables. Matches one digit of a different phone number. For example, "E" is included in the second digit, and "0"-
If “6” and “9” and “#” and “*” are included, this “E” matches any of “7” and “8”.

In the detection table 27a, the detection numbers are arranged in descending order of the number of digits and in the order of priority ((including "A")> normal telephone number> (including "E"). Are arranged on the memory in a state where the tables (0 to 63) are sorted in a higher order (corresponding to the upper part in FIG. 4).

Next, the conversion instruction command is represented by codes of "I", "K", "C", and "D", and means the next operation.

I: The access code indicated by the access table number specified after the command is inserted before the detection data (detection number).

C: The detected data (detection number) is converted into the access code indicated by the access table number specified after the command.

K: Holds the detection number.

D: Delete the detection number.

The access table number in the detection table 27a corresponds to the access code table 27 on the right side of FIG.
The index (number) itself in b indicates the index (number) in the access code table 27b to be referred to following the conversion instruction commands 'I' and 'C'.

The access code table 27b in FIG.
It consists of a plurality of tables (six in FIG. 4, 1 to 6) including access codes for each communication carrier, and the index number of each table is the detection table 27a as described above.
It is stored therein as (3) access table number.

Therefore, for example, when the table “001C1” in the fifth row (index 05 :) of the detection table 27a on the left side of FIG. 4 detects the number “001”, the access code table 27b accesses the index “1”. This indicates that the code “0041” is extracted and the detected “001” is replaced with “0041” (“C”).

The table "01A0K" in the second row (index 02 :) starts with "01", an arbitrary digit is inserted at the position of "A", and ends with a telephone number ("0130", "0"). "0190") means to hold ("K") as it is.

Next, a flowchart of FIGS. 5 and 6 shows a telephone number conversion method using the detection table 27a. 5 and 6 correspond to a telephone number comparing step and a telephone number converting step in the ROM 26 of FIG. In the following flowcharts, counters such as i and j, variable areas, and the like indicate registers of the CPU 21 and DR unless otherwise specified.
It is assumed that an appropriate area on the AM 27 is used. In addition, a storage location in the flowchart, a mnemonic indicating an operation ([] indicating an array, and +
As +, or == indicating data coincidence, a notation substantially equivalent to that used in the C language or the like is used (the same applies to any of the following flowcharts).

FIG. 5 shows a character string (dial data) of a telephone number input from the input device 22 and a detection table 27a.
2 shows a comparison process of the data in.

In step S501, from the dial data stored in the dial buffer dial_buf, an effective character string of the maximum digit length (six digits) of one entry of the detection table is obtained, and the buffer temp_buf (secured in the work buffer 27g). ). Dial buffer dial_buf, buffer temp_b
uf is a work buffer 27g in the DRAM 27 of FIG.
It is assumed that Where the valid characters are
"0"-"9", "#", "*", and the input telephone number contains pseudo control data such as "T" (tone), "P" (pause), space, etc. If any, these strings are excluded. get_active_digit ()
Indicates a function (subroutine) not shown, for reading data from the dial buffer dial_buf,
And conversion to the valid characters described above.

In step S502, an initial value 0 is substituted for a counter i (a counter for indexing a plurality of detection tables). That is, the counter i is initialized to indicate the 0th (first) table in the detection table 27a.

In step S503, if the counter i exceeds the predetermined number of detection tables or if the i-th detection table is an invalid table (a table with no data), it is determined in step S517 that there is no matching detection table, and Move to telephone number conversion process.

When the counter i is smaller than the number of detection tables,
If the i-th detection table is not an invalid table,
The process proceeds to step S504, and the detection number data of the i-th detection table (only the (1) detection number portion of the table) is acquired in the buffer main_buf. This buffer m
ain_buf is also secured in the work buffer 27g, and the following character comparison processing is performed in this buffer main_buf.
This is executed for the detection number data in buf and the input telephone number data in temp_buf.

In step S505, the detection table 27
obtain the detection number data length of the i-th table in a,
Store it in the variable length. That is, in this case, in order to compare the telephone numbers from the right side, the (1) detection number portion (the portion stored in the buffer main_buf) of the table
Is obtained and stored in the variable length.

In step S506, the initial value (length-1) is substituted for the character string comparison counter j, and the loop from step S507 is executed a number of times corresponding to this length.

In step S507, it is determined whether or not the counter j is equal to or greater than 0 (that is, whether or not a character having a value of length has been processed). If the counter j is equal to or greater than 0, the process proceeds to the character data comparison process in step S508. At this time, the loop is ended, and the process proceeds to step S516, where the detection table (corresponding to the value of the counter i) at this time should be used (that is, the detection table in FIG.
Shift to character conversion processing.

In step S508, first, the j-th character is obtained from the detection number data in the detection table. That is, the data of main_buf [j] is obtained in the one-digit buffer main_digit.

In step S509, similarly, the j-th character is obtained from the effective character string (temp_buf) of the dial data (chk_digit ← temp_buf).
[J]).

In step S510, main_dig
It compares the contents of it and chk_digit (main_
digit == chk_digit), it is determined whether or not they match, and if they match, the counter j is decremented (step S519), and the flow shifts to step S507 to check the next digit. That is, the detection number data in the buffer main_buf and temp_b
The comparison with the input telephone number data in uf is
It is performed from the right by th.

If the digits do not match in step S510,
In step S511, the j-th character string of the detection number data of the current detection table, that is, main_digi
It is checked whether the content of t is a metacharacter "A" (matches all telephone number codes). If step S510 is affirmed, the process proceeds to step S507 via step S519, assuming that this digit has matched.

If step S511 is denied,
The process moves to step S512, and next is main_digit.
Is a metacharacter "E".

In the case of the metacharacter “E”, chk_d
One digit of the input telephone number in the igit is the detection table 27a.
If it is not registered at the same digit position in another table in the table, it is determined to be a match, so that the processing of steps S513 and S514 is performed.

That is, in steps S513 and S514, chk_digit (temp_buf [j]) is added to the same j-th digit in the detection number data of another detection table.
Check if there is the same code as the character code of, and if there is the same code in other detection table,
In step S515, it is determined that the i-th detection table does not match the dial data (assuming that the metacharacter "E" does not match), and in step S518, the counter i is incremented (i ← i + 1), and
Return to 503.

On the other hand, in step S514, chk is added to the same j-th digit of the detection number data of the other detection tables.
If there is no code that is the same as _digit (temp_buf [j]), it is determined that the code matches the metacharacter “E”, and the process returns to the step S507 via the step S519. In other words, the process proceeds to the next digit comparison.

On the other hand, in step S512, main_di
If git is not “E”, it means that no match was detected in the comparison of this digit, and therefore, step S5
In step S15, it is determined that the i-th detection table does not match the dial data.
Return to 03.

By executing the above steps, the following two results are obtained from the telephone number detection processing. Step S516: The detection table i is obtained from the dial data.
Are obtained. Step S517: No match table is obtained.

After the comparison processing of FIG. 5, the telephone number conversion processing of FIG. 6 (corresponding to the telephone number conversion step in the ROM 26 of FIG. 2)
Perform

In step S601 of FIG. 6, the result of the telephone number detection processing of FIG. 5 is checked. If there is no matching detection table, nothing is performed in the telephone number conversion processing, and the telephone number calling processing (S305 of FIG. 3) is performed. ). If there is a matching detection table in the telephone number detecting process, the process proceeds to step S602.

In step S602, a conversion command of the matching detection table is acquired in the buffer cmd (secured in the work buffer 27g). The conversion processing command is obtained by searching for a code that is not a number from the right of the matching detection table. Step S60
3, in S604, S607, and S610, the buffer cm
The conversion processing command in d is “K”, “C”, “I”,
It is determined which of “D” matches (==).

If cmd == 'K' in step S603, the telephone number conversion process ends without doing anything.

In step S604, if cmd == 'C', the process proceeds to step S605 to obtain an access code from the access table number in the detection table, and further detects the detection number character of the dial data input in step S606. Convert a column to an access code. In other words, of the input telephone number (use the tone, pause, space, etc. in temp_buf removed)
The part matched in the detection processing of FIG. 5 is replaced with the contents of the access code table referred to by the access code table number following C. The table “001” in the previous example
In the case of "C1", "00"
The part “1” is converted by the access code “0041” referred to by the index “1”.

In step S607, cmd ==
In the case of "I", in step S608, an access code is obtained from the access table number of the detection table, and inserted in step S609 before the matched part of the input telephone number. For example, in the case of the table “075I2” in the sixth row (index 06 :) in FIG.
“0088” is extracted from the access code table with index = 2 before “5” and inserted before “075” to form a telephone number pattern of “00888075”.

In step S610, cmd ==
In the case of "D", in step S611, the character string of the matched part of the input telephone number is deleted from the dial data.

In the case of another conversion processing command (when all of steps S603, S604, S607, and S610 are denied), nothing is performed in the telephone number conversion processing.

As described above, the telephone number is converted, and a call is made using the converted telephone number data. The dialer is included in the NCU 25 in the present embodiment, and the telephone number data obtained as described above is N
Supplied to the CU 25, the NCU 25 forms a dial signal based on the telephone number data and sends it out to the line.

As described above, the conversion (cmd == 'C'), insertion (cmd == 'I'), and deletion (cmd = 'D') of the detection number in FIG. Since the process is performed on a valid character string in which “T” (tone), “P” (pause), space, etc. are deleted from the number, invalid character strings such as pause and tone are included in the detected character strings. Even if it is, the code is deleted and used for calling.

Next, the receiving means (downloading) of the detection table data and the data update processing will be described with reference to FIG.

The detection table data is stored in the remote center 7
0 and downloaded to the communication device of each user. It is assumed that the remote center 70 is operated by a manufacturer or a communication carrier that supports the apparatus of this system.

The table data and control data received from the remote center 70 are stored in the SRAM 28 once.
After being stored in the receiving table area, it is activated based on the control of the RTC 24. Information on the date and time at which the validation should be performed (1:01 on January 1 in FIG. 7) is included in the data received from the remote center 70 as update date and time data.

In FIG. 7, in order to download the table data and control data from the remote center 70 to the communication device and to enable the detection process of the communication device, download communication of the detection table data is performed by a facsimile procedure signal ( Step S701). In the case of FIG. 7, the download date and time is 19:10 on December 7.

This download is performed when the user performs a predetermined operation from the input device 22 of the present apparatus, or calls the device to be maintained from the remote center 70 as necessary. You may do it.

The updating table data received from the remote center 70 is stored in the table area 28a of the SRAM 28,
28b and control data is stored in area 280.
The update date and time is stored in the area 28i of the SRAM 28 (Step S702). Thus, the received data is SRA
The data is stored in M28 and is not erased even if the power of the communication device is turned off.

On the other hand, the data (the detection table and the access code table described above) referred to in the telephone number detection processing is used as actual operation memory separately from the reception memory, and the update date and time data (9 in FIG. 7). At 2:00 on the 15th of the month) (step S703).

In other words, the data currently in use is valid at 2:00 on September 15, and this data is used until the updated date and time of updated new data, January 1, 1:01. . The determination as to whether the update date and time has come is implemented by timer interrupt processing or the like, and the time data read from the RTC 24 at predetermined time intervals (for example, one minute) is compared with the update date and time of the new data in the SRAM 28 in units of minutes. (Step S704). As a result, if the update date and time in the data receiving memory has not been reached yet, the detection processing using the previously downloaded data is continued (step S705).

When the clock time of the RTC 24 reaches (or exceeds) the update date and time, the data area 2 of the SRAM 28
The table data, control data, and update date / time data are copied from 8a, 28b, 280, and 28i to the actual operation data areas 27a, 27b, and 270 of the DRAM 27 (step S706). In this copy processing, the sort of the detection table described above is also performed at the same time.

Since the memory for the actual operation is the DRAM 27, the same new detection table data for the actual operation is copied on the SRAM 28 for backup. In the event of an abnormality in the apparatus or when the main power is turned on again, the backup data can be copied back to the DRAM 27 and used.

In this manner, various data tables copied to the data area for actual operation of the DRAM 27,
The control data is used at the time of dialing (step S707).

As described above, the telephone number conversion data (line selection information) is downloaded, and the data received after the download is automatically converted to the telephone number at the update date and time designated by the remote center 70. It can be set in the actual operation table used during operation. This activation requires no user interaction,
For example, it can be performed completely automatically in accordance with a time such as a revision of a charge of a communication carrier.

When the update date and time data received from the remote center 70 is 0:00 on 00:00 on October 0, the copy from the reception memory to the actual operation memory is performed immediately after the download is completed. It is better to do it. As a result, the received detection table data can be validated immediately after the download is completed. Therefore, it is possible to forcibly update the line selection information to new data or the like for the convenience of the center.

It is preferable that the detection table data and the access code table as the line selection information can be deleted by a procedure as shown in FIG. For example, when relocating equipment such as moving, detection table data is
If the access code table can be deleted, the telephone number conversion process will not be performed by old invalid data.

The process shown in FIG. 8 is an all-clear process for initializing the state of the apparatus when the product is shipped, moved, or the like. This all-clear process is started by performing a special key operation with the input device 22. For example, it is realized by the following key operation.

1. 1. Press “Registration key” 2. Press '#' key Pressing the up / down (↑ ↓) key displays the CLEAR menu on the LCD.

4. Press the SET key to enter the CLEAR menu.

5. Press the up / down (↑ ↓) key to enter ALL
Display the CLEAR menu.

6. All clear is executed by pressing the SET key.

Each menu may be displayed together with a number so that the menu can be selected by operating the ten keys.

When all clear is selected by the above-described operation, in step S801 in FIG.
Various settings in the data area 270 of the AM 27 (telephone number conversion operation control data 27c to 27f) or other software SW, one-touch dial data, and the like are cleared.

In step S802, various data (detection table data, access code table, etc.) in the data receiving data areas 28a, 28b in the SRAM 28 are cleared.

In step S803, this time the DRAM 2
Various data (detection table data, access code table, etc.) in the actual operation data areas 27a, 27b on the 7 side are cleared.

The clearing of various data for data reception in step S802 and the clearing of various data for actual operation in step S803 are performed in steps S804 to S80.
8 is performed.

Here, the detection table (27a or 2
8a) is filled with invalid data (a code not used as data, for example, a pattern such as 0xee) (step S804), and the access code table (2
7b or 28b) are all filled with invalid data. (Step S805) Update date / time data (DRAM area 28i, etc.)
Is written as invalid data (step S806), and the telephone number conversion operation control SW 27c is set to "0" (no conversion) (step S807).

Also, a checksum is calculated to check the data when the power is turned on (step S808). This checksum is for checking whether or not the control data is broken. The checksum is obtained by summing up the data of the area that needs to be checked and writing it in a predetermined area. Such a checksum is to be executed at an appropriate timing that can guarantee the validity of data even in the above-described download process and the like.

When the data in the detection table is erased by the above processing, the apparatus starts from step S306 in FIG.
Phone number detection processing in step S303, step S30
The process proceeds to the telephone number calling process of step S305, bypassing the telephone number conversion process of No. 4, and the line selection function does not operate.

When the all clear is executed, various data for the detection table is downloaded from the remote center 70, and the line selection function does not function until the update date and time included in the download data has passed.

Next, a method of changing and erasing the detection table data from the remote center 70 will be described with reference to FIGS. The all clear method in FIG. 8 clears all the data in the detection table so that the telephone number conversion process cannot be executed when the device is shipped or when the device is relocated. Is a method of clearing only a part of data such as a detection table (for example, one of the tables in FIG. 4).

FIG. 9 shows a download process.
This download processing is performed via a telephone line by calling the present apparatus from the remote center 70 side.
That is, the communication device connects to the remote center 70 by responding (receiving) to a signal transmitted from the remote center 70 (step S901).

The communication between the remote center 70 and this apparatus is started by executing pre-download processing by a facsimile procedure signal (step S902). That is, it is recognized by both parties that facsimile procedure signals such as NSF, DIS, NSS and NSC signals are exchanged and that line selection information is updated by non-standard communication instead of normal facsimile communication. In the pre-processing, the remote center 70 determines the model name and the R of the communication device.
An OM version or the like is obtained, and preparations are made to transmit appropriate line selection information.

Thereafter, a download command receiving process is executed (step S903).

First, after a communication speed negotiation is performed by training, a download command (shown in FIG. 10 described later) is received by an image data signal in facsimile communication. That is, the command is transmitted and received as a facsimile message, and the error correction processing (ECM procedure: PPS) is performed similarly to the facsimile communication.
(Using facsimile procedure signals such as EOP, PPR, CTC, and CTR), it is possible to prevent garbled characters in received data and loss of data.

When the download command is received, the download command analysis process (described with reference to FIG. 10) is started (step S904). This analysis processing is executed by a loop of steps S905 and S906. That is, if the download command is being analyzed in step S905, the process proceeds to step S906, and if the analysis is completed, the process proceeds to step S907. In particular, step S9
At 06, the RNR (Receiviv
er Not Ready) signal. After the RNR transmission, if an RR (Receive Ready) signal is received from the remote center 70, the process returns to step S905 to continue receiving commands one by one.

When the analysis is completed, download end processing is performed (step S907). Here, as a result of command analysis, if the download data is registered normally,
An MCF signal is transmitted to notify the remote center 70 that the reception was successful, and if registration of the download data failed, an RTN signal is transmitted to notify the remote center 70 that the reception failed.

Finally, from the remote center 70, the DCN
Upon receiving the signal, release the line and terminate.

FIG. 10 shows the format of a command in this embodiment. These commands correspond to data such as tables and SW stored when data is received. By giving data to be set after the command, various settings corresponding to each command are provided on the device side. Register the data. By using “CR LF” as a delimiter between commands, a plurality of commands can be stored in a facsimile message frame and transmitted.

Note that "CR LF" is 0 in the ASCII character set.
x0d 0x0a, which corresponds to a return / line feed control code, may be any other EOL (End Of Line) code (for example, CR only). In the figure,
In order to indicate a logical EOL code, "CR" and "LF" are shifted in a staggered manner. In the present embodiment, mnemonics such as FNG, FNF, etc. in FIG. 10 are literally “FNG”, “FNF”, etc.
It is assumed to be a character string of an ASCII code, or may be represented by a predetermined binary pattern.

In FIG. 10, the FNG command is for registering the telephone number conversion operation SW (27c in FIG. 2). For example, FNG1 CR LF: SW is ON. FNG0 CR LF: SW is OFF. is there. That is, the CPU 21 of the present apparatus
G1 turns on telephone number conversion operation switch 27c, FNG
A registration process is performed so that the telephone number conversion operation switch 27c is set to OFF by 0.

The FNF command registers a prefix (external line number in the second embodiment) table use SW used in a second embodiment to be described later.

The FNU command is stored in the area 28 of the SRAM 28.
In order to register the data update date and time of 8i, for example, a command such as FNU12 / 12 12:12 CR LF is used as the update date and time on December 12 at 12: 1.
Specify 2 minutes. That is, when this command is executed, the DR is read from the SRAM 28 at 12:12 on December 12.
The data is copied as data for actual operation by the processing of the AM 27 shown in FIG.

In the present invention, the year part of the data update date and time is omitted. However, for the year data, the current date and time are compared with the registered data, and the date and time data before the current date and time are registered. When it is received as data, it will be registered as data to be updated next year. This is to prevent confusion when registering until the year, because the year differs from the Christian calendar and the Japanese calendar.

The FNP command registers a prefix table (corresponding to the outside line calling number table 27f in FIG. 2) used in the second embodiment.

FNP00 CR LF means that a table having the prefix "0" to be detected as the 0th prefix table should be registered.

The FNM command is for registering one table in the detection table 27a described with reference to FIG. For example, FNM01001C1 CR LF is the number 01 table in the detection table 27a.
This means that table data having the content "001C1" should be registered.

The FNN command is for registering one table in the access code table 27b described with reference to FIG. For example, FNN0001 CR LF is "001" as the 0th access code table.
It means registering the table data of.

In each command of FIG. 10, FIG.
By writing invalid data (0xee, etc.) as shown in relation to the above, the data of the table can be invalidated, that is, deleted, and this "deletion" can be considered as one mode of changing the table. Can be.

FIG. 11 shows the download command analysis processing performed in step S905 of FIG. In steps S1101 to S1104, the first three characters of the received command data are compared with the mnemonics FNM, FNN, FNG, and FNU of the command (FIG. 10). Shifts to the registration process.

Steps S1105 to S1109
In the registration processing described in FIG. 10, the registration processing described with reference to FIG. 10, that is, the detection table, the access code table, the telephone number conversion operation SW, and the update date and time are executed.

Steps S1101 to S1104
If all the commands do not match, step S11
Then, the process proceeds to 13 and it is determined that the download is abnormal.

When the process goes through each registration process, step S111
If it is 0, it is determined whether the registration has been completed normally. This determination is made by reading the written data again.

If the registration process has been completed normally, the process proceeds to step S1111.
Go to step 13.

In step S1111, it is checked whether there is still download data to be processed. If there is no download data to be processed, the process proceeds to step S1112, where the analysis is completed, and if there is still download data (during analysis), step S1101 is performed. And execute the next command analysis.

When the analysis of the download data is completed in step S1111, in step S1112, a normal download process (step S907 in FIG. 9) for notifying the normal end to the download end process is executed. On the other hand, in step S1113, Then, a download error process (step S907) for notifying the download end process that the download data is not normal is executed, and the download command analysis ends.

FIG. 12 shows the registration processing of the detection table in step S1105 executed based on the download. In the detection table registration processing, data can be changed or deleted for each table data of the detection table.

As described above, the command for registering the detection table has the format of FNM <table number><detection table data> CR LF, so the table number (index) portion is obtained from the command data in step S1201. In step S1202, it is checked whether the number is within the range of the table number (for example, 0 to 63 in FIG. 4). If the number is within the range, the process proceeds to step S1203. If the number is outside the range, the process proceeds to step S1209.

In step S1203, it is checked whether the corresponding table data exists. If so, step S1204; if not, step S1205.
Move to

In step S1204, the received table data is copied to a data buffer for registration.

In step S1205, the invalid data is stored in the registration data buffer (table area 28 of SRAM 28).
Copy to a). In step S1206, the part of the detection table data of the command is copied from the registration data buffer to the detection table specified by the table number in the command.

Further, in step S1207, it is checked whether or not "CR LF" as a terminator exists. If there is, the flow shifts to step S1208, and if not, to step S1209.

In step S1208, the fact that the registration has been normally completed is notified to step S1110 in FIG. 11, and in step S1209, the fact that the registration has been abnormally notified is reported to the step S1110 in FIG.

By performing the above registration processing, the data of the detection table can be changed.

In particular, regarding the erasure (clear), when the detection table registration command FNM <table number><detection table data> CR LF omits the portion of the detection table data,
A desired detection table can be cleared by handling to clear the detection table data related to the table specified by the table number.

Therefore, by transmitting / receiving an arbitrary registration command to / from the remote center 70, an arbitrary portion of the detection table as line selection information can be changed (or newly registered) or deleted. , Thereby changing the line selection operation of the device. For example, by manipulating the data update date and time by the FNU command, the time at which the line selection information is validated can be controlled from the remote center 70 side.

FIG. 12 shows the process of registering the detection table. However, the process of FIG. 12 can also be applied to the process of registering other commands in FIG. 10, thereby changing and deleting each registered data. Becomes possible.

As described above, in the communication apparatus for automatically selecting one communication carrier line from the data such as the area code and the communication carrier access number of the telephone number data input by the user, the data of the detection table data By providing means for changing (or newly registering) and erasing the portion, the presence or absence of the line selection function of the communication device can be set.

According to the above embodiment, it is possible to perform a telephone number conversion process and select a line carrier.
Without the user knowing which line to use,
Various communication lines can be used effectively.

The line selection information is implemented as a detection table and an access code table for telephone number detection and conversion as shown in FIG. 4, and is excellent in maintainability of the line selection information. For example, a detection table,
Further, by changing only one of the access code tables, it is possible to easily cope with a fee revision or a relocation of a device due to relocation or the like.

A table for detecting a telephone number is shown in FIG.
As shown in (1), by using a detection number + conversion instruction command + access code and sorting them in ascending order of the number of digits, the detection and conversion process from the telephone number input by the user is shortened and simplified. Further, since the conversion instruction command is implemented by one character, a wide range of conversion processing such as I (insert), K (hold), C (change), D (delete) can be performed with a small storage capacity. . Further, by including special codes (metacharacters) "A" and "E" in the detection number portion of the detection table, memory can be saved.

That is, even in a device such as a facsimile device having a limited storage capacity, data for telephone number conversion can be efficiently stored.

If an operation means for changing the telephone number detection table is prepared as appropriate, the user's preference (for example, use KDD for all international calls, use NTT for all dials near Tokyo, etc.) Also, it is possible to use the line.

Since the telephone number detection table can be deleted, the line selection function does not operate normally with the downloaded detection table data when the user or the communication device at the time of the new purchase is moved by moving or the like. Can be prevented. Further, it is possible to select whether or not to activate the line selection function depending on whether or not there is a telephone number detection table.

Further, since the detection table, access code table, and other control information as line selection information are downloaded from a remote center using a facsimile procedure, existing facsimile communication means is used in a facsimile apparatus or the like. Utilization can be used to easily implement processing such as updating, changing, and deleting line selection information.

When the facsimile procedure is used, the line selection information is manipulated as an image message (change, delete).
In this case, the line selection information can be reliably received without error by performing the ECM communication, and the line selection can be reliably performed based on the correct line selection information.

When the facsimile procedure is used, each table constituting the line selection information and control data can be changed using a command as shown in FIG.
Each table and control data can be changed individually.

As shown in FIG. 7, the line selection information downloaded from the remote center includes update date and time information for validating the detection table, the access code table, and other control information. Based on this, it is possible to automatically determine the use start point of the downloaded line selection information at an appropriate timing such as a fee revision.

In particular, as described above, when the update date and time data is 00:00 on 00:00, the downloaded line selection information is validated immediately after downloading, so that immediately after the initial installation of the apparatus (or In the case of, for example, deleting a table immediately after moving, etc. (for example, when there is no valid table data at all), the remote center transmits line selection information with the update date and time data set to 00:00 on 00:00, or The apparatus operates by imitating that such update date and time data has been transmitted, so that the downloaded line selection information can be immediately validated and line selection can be started by telephone number conversion based on the information.

The detection table and the access code table can be erased as invalid by a simple process of writing invalid data. In particular, the reception of the command as shown in FIG. By preparing a user interface for performing a process corresponding to (1), invalidation (deletion) can be performed for each individual table entry.

(Second Embodiment) Hereinafter, a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, processing of an outside line calling number (prefix) is added to the calling control shown in the first embodiment.

FIG. 13 is a flowchart of a calling process corresponding to FIG. 3 of the first embodiment, and shows an outline from a telephone number input process to a calling process as in FIG. In the telephone number conversion process when using an outside line calling number, if an outside line calling number is detected, it is removed, necessary telephone number conversion is performed, and the removed outside line calling number is added again to make a call. Make a call.

Steps S1301 to S130 in FIG.
The processing of 1305 corresponds to steps S301 to S305 in FIG. 3 in the first embodiment, and the input of the telephone number from the input device 22 and the telephone number conversion S
The determination of the state of W27c and the detection / conversion / calling processing of the telephone number using the detection table are performed.

In FIG. 13, if the telephone number conversion switch 27c is set to "convert" in step S1302, in step S1306 the SW for determining whether or not to refer to the outside line calling number table 24f is determined.
The setting state (27e in FIG. 2) is checked. Then, when referring to the outside line calling number table 24f, step S13
07, and if not referenced, step S1303
Then, the process directly shifts to the telephone number detection process.

The external line calling number table 27f can be configured in the same format as the detection table or the access code table in FIG. 4, so that a plurality of external line calling numbers to be detected can be registered. The outside line calling number table 27f may be configured to use metacharacters and conversion instruction commands as in the first embodiment. However, in the case of an outside line calling number, since complicated conversion is not performed, for example, FIG. Like the access code table, the data of the outside line calling number to be removed prior to the telephone number conversion is stored in the outside line calling number table 27f simply in a format such as 01: 0 02: 0 # 03: 0 PAUSE. You may just put it.

In step S1307, each outside line calling number in outside line calling number table 27f is compared with the beginning of the input telephone number (this can be performed by the comparison processing as shown in FIG. 5). In step S1308, if it matches the outside line calling number in the table, step S1
The process proceeds to step 309, and if they do not match (if the private branch exchange is used, it is an extension call), step S1
The process proceeds to a telephone number calling process of 305.

In step S1309, an outside line calling number is deleted from the dial data to remove the detected outside line calling number. Then, steps S1303 and S1304
Detection / conversion processing (same as that described in FIGS. 5 and 6)
Is performed and the outside line calling number is deleted, the deleted outside line calling number is added again in step S1310.

As described above, the outside line calling number is detected, the number is removed, the telephone number is converted, and the outside line calling number is added again, so that the communication line connected to the private branch exchange etc. When it is necessary to specify the calling number, the telephone number conversion process is performed in the same manner as in the first embodiment, and the line carrier can be selected.

The data in the outside line calling number table 27f can be downloaded, changed, or deleted from the remote center 70 by the method described in the first embodiment. In particular, the outside line calling number table 27f
Registration to the command F from the remote center 70 side
NP (FIG. 10).

[0178]

As described above, according to the present invention,
In a communication device that selects and transmits one of lines provided by a plurality of communication carriers, a communication method of the communication device, and a computer-readable recording medium storing a control program of the device, the communication device includes: A detection number corresponding to a telephone number to be converted to an access code, a conversion instruction command for instructing a telephone number conversion method when the detection number is detected, and a telephone number conversion when the detection number is detected Storing a detection table including data of the access code of the carrier as line selection information,
The telephone number input from the input means is compared with the detection number in the detection table of the line selection information storage means, and the converted telephone number is supplied to the calling means for calling. It is excellent in maintainability of line selection information, and can easily convert telephone numbers required for line selection with a small storage capacity.

Alternatively, by adopting a configuration in which a regular expression is used as a detection number corresponding to a telephone number to be converted to an access code of a communication carrier in the detection table, further memory can be saved, and the facsimile apparatus can be further reduced. For example, a telephone number required for line selection can be easily converted with a small storage capacity even in an apparatus having a limited storage capacity.

Alternatively, the outside line calling number to be removed at the time of comparing and converting the telephone numbers is stored in the outside line calling number storage means, and the inputted telephone number is stored in the outside line calling number storage means. Detecting whether a number has been added or not, and if an outside line calling number has been added, remove the outside line calling number from the input telephone number, compare the telephone number and convert the telephone number, By adopting a configuration in which the converted outside phone number is added to the removed outside line calling number and then used for outgoing calls, even when a communication device connected to a private branch exchange etc. needs to specify the outside line calling number, It is possible to perform a number conversion process and select a line carrier.

Alternatively, an ECM method or the like is used by a configuration in which the line selection information to be stored in the line selection information storage means or the outside line calling number in the outside line calling number storage means is received by using a facsimile communication procedure. As a result, the line selection information can be received without error, and the line can be reliably selected based on the correct line selection information. In a facsimile apparatus or the like in which a facsimile communication procedure has already been implemented, the DTMF receiving means or the external LCR It is possible to select a line carrier without adding extra means such as an adapter.

Alternatively, when receiving the line selection information or the outside line calling number using the facsimile communication procedure,
By receiving the update date and time data for validating the line selection information or the outside line calling number and determining the date and time for validating the received line selection information or the outside line calling number based on the received updated date and time data, The use start point of the downloaded line selection information can be automatically determined at an appropriate timing such as a fee revision.

Alternatively, a configuration is employed in which the line selection information in the line selection information storage unit is changed by receiving a command to change the line selection information in the line selection information storage unit using a facsimile communication procedure. As a result, individual data constituting the line selection information can be individually changed.

Alternatively, by adopting a configuration in which the line selection information in the line selection information storage means or the outside line calling number in the outside line calling number storage means is erased, the apparatus can be installed at the time of initial installation or relocation. At the time of relocation, the old line selection information and the outside line calling number can be invalidated, so that incorrect line selection can be prevented.

Alternatively, by adopting a configuration in which predetermined invalid data is erased by writing predetermined invalid data as the line selection information in the line selection information storage means or the outside line call number in the outside line call number storage means, a simple structure is adopted. By the processing, the line selection information and the outside line calling number can be erased as invalid data. In particular, individual line selection information in the line selection information storage means can be erased individually as invalid.
