Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device and a terminal adapter device, and more particularly to a communication terminal device and a terminal adapter device provided with transmission restriction control means for restricting transmission to a communication destination.

[0002]

2. Description of the Related Art Conventionally, as a communication terminal apparatus as described above, as shown in FIG. 7, a call originating from a telephone set 2 for judging whether or not a number originated from a telephone 2 matches a registration number subject to call origination restriction and performing call origination restriction. Terminal adapter device 1 with regulation function
00. In many cases, the method of comparing the number called from the telephone 2 with the registration number subject to the call restriction is performed from the first digit of the data (information) registered in the registration table, and It is determined by whether or not all digits match with the registration number subject to outgoing call restriction.

[0003] Specifically, a telephone number or a character string that is a partial number of the telephone number is registered in the storage unit of the terminal adapter device 100 as information relating to the transmission restriction target. When making a call, the number called from the telephone 2, which is an analog terminal, is compared with this registered content from the first digit, and if they match, no call command is sent to the network side of the ISDN line 7, A busy tone is transmitted to the telephone side to notify that transmission from the analog terminal is impossible.

[0004] It should be noted that the number of the information related to the transmission restriction object is generally any number as long as it is less than the maximum number of digits (for example, 32 digits). That is, for example, when "0" is registered with one digit, transmission to outside the city can be restricted. Further, for example, when restricting transmission to a specific pay service, transmission can be restricted by registering a number corresponding to the communication service.

[0005] Recently, the use of communication services by a plurality of telecommunications carriers or the provision of various types of networks as communication services has become common. in this case,
Number specifying business operator or special number (1XY system etc.)
Is often added to the beginning of the calling number. However, in the case of the above-described call barring control, for example, even when only one number is subject to the barring of calls, it is necessary to consider various call patterns including a number specifying a business operator or a special number. , It was necessary to register multiple types. It should be noted that, for example, call numbers used in an emergency such as 110 and 119 are generally considered so as not to be registered in this regulation.

[0006]

However, with respect to the release of the transmission restriction in the above-described conventional technology, no consideration has been given to special numbers (such as 1XY) other than the calling number used in an emergency. In addition, registration of a number to be subject to transmission restriction is performed only by sequentially writing from the first digit. Therefore, it is not possible to register such that only a desired arbitrary number of digits are designated, that is, to register a predetermined number of digits as an arbitrary number such as designating a specific dial pattern. For example, when regulating a communication carrier (00XY), only a method of registering each communication carrier has been provided.

Further, in the above-mentioned method, only outgoing call regulation is assumed, and for example, a specific number which is not expected to be outgoing call, which is assumed as an actual use method of the communication terminal device, is considered. Did not. Therefore, for example, when registering the above-mentioned special number so as to be excluded from the regulation target, a special number is used in addition to the number to be restricted, and all possible dial numbers are registered (for example, 184 + restriction number, 186 + restriction). Number, etc.), and the registration takes time.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to easily regulate outgoing calls when assigning a special number, a communication carrier, or the like before a calling number. It is an object of the present invention to provide a communication terminal device and a terminal adapter device that can register a calling number (calling restriction release number) excluded from a restriction target.

[0009]

In order to achieve the above object, a communication terminal apparatus according to the present invention comprises a communication restriction control means for restricting transmission based on information registered in a registration table. A communication terminal device connected to a line, wherein the registration table is capable of registering a transmission restriction target and a transmission restriction release target.

Specifically, function setting means for receiving a PB signal transmitted from an existing analog terminal such as a telephone connected to an analog port serving as an R point interface and performing various function settings such as a communication function; In a terminal adapter device connected to an ISDN line having a transmission restriction control means for restricting transmission based on the information registered in the registration table, the registration table can register the transmission restriction target and the transmission restriction release target in the registration table. In addition, as the character string to be registered, a specific number of digits of the PB signal of the call information from the analog terminal can correspond to any dial number.

Thus, the transmission restriction target and the transmission restriction release target are included in the registration table referred to by the transmission restriction control means. As a character string to be registered in the registration table, R
PB of call information from an existing analog terminal such as a telephone connected to an analog port to be a point interface
The outgoing call barring control can be performed using a specific number of digits of the signal as an arbitrary dial number.

A communication terminal device according to this embodiment is a communication terminal device which is connected to a communication line and includes a transmission restriction control means for restricting transmission based on information registered in a registration table. Can be registered as a transmission restriction target and a transmission restriction release target.

More specifically, function setting means for receiving a PB signal transmitted from an existing analog terminal such as a telephone 2 connected to an analog port 16 serving as an R point interface and performing various function settings such as a communication function. And the terminal adapter device 1 connected to the ISDN line 7 including transmission restriction control means for restricting transmission based on the information registered in the registration table. Can be registered, and the character string to be registered can correspond to any dial number with a specific number of digits of the PB signal of the call information from the analog terminal.

More specifically, this terminal adapter device 1
Is, for example, as shown in FIG.
, Display unit 13, storage unit 14, analog port control unit 15
And analog port 16 and U point interface 17 and S
/ T point interface 18.

The control unit 11 controls the terminal adapter device 1 based on the processing program stored in the storage unit 14.
It performs the entire operation control process and is formed by, for example, a microprocessor. The operation unit 12 is for setting an operation mode of the terminal adapter device 1 and the like, and is formed by, for example, a dip switch. The display unit 13 is for displaying an operation state of the terminal adapter device 1 and the like. It is formed to include a liquid crystal display element and an LED element for displaying a communication status.

The storage unit 14 stores various processing programs such as transmission restriction control means and function setting means executed by the microprocessor of the control unit 11, setting values relating to each processing program or various function settings, transmission restriction targets and transmission It stores data such as a registration table of information related to the restriction release target, and includes ROM (read only memory), RAM
(Read-write memory) or EEPROM (electrically rewritable memory). Various settings for the terminal adapter device 1 for using the ISDN line 7 are written in the EEPROM so that the set values do not disappear even when the power is turned off.

The analog port 16 connects an existing analog terminal such as the analog telephone 2, the G3 facsimile device 3 or the analog modem device 4 (constituting an R point interface), and is controlled by the analog port control unit 15. , In this case, two are provided. The analog port control unit 15 turns on the analog terminal,
Off-hook detection, generation of ringing for calling, or detection of a push button signal (PB signal) for a call operation from the analog terminal as described above. The analog port control unit 15 includes a signal sequence detecting unit that detects a PB signal sequence that changes a state of setting various functions such as a communication function by the function setting unit. Note that analog terminals are usually connected to the analog port 16 one by one for each analog port 16, but as shown in FIG.
One or more analog terminals may be used in a branch connection.

The U point interface 17 and the S / T point interface 18 are controlled by the control unit 11 to connect the terminal adapter device 1 to the network of the ISDN line 7 and to connect the signal channel (D channel) and the 2 The signal is integrated and separated and converted into two information channel (B channel) signals. The U point interface 17 is the end of the network function,
The / T point interface 18 has a digital telephone 6
And an ISDN device such as a PC network device (not shown).

Conventionally, various settings in the terminal adapter device 1 for using the ISDN line 7 are performed by an analog terminal such as an analog telephone 2 connected to an analog port 16 or a personal terminal connected to a serial interface (not shown). It was performed by a computer (PC) 5. When the analog telephone 2 is used, various settings are made by a combination of PB signals (however, a combination including a function number not used in the telephone number plan is used). E above
Written to EPROM.

In the present invention, as shown in FIG. 3, the registration table of the storage unit 14 can register a plurality of transmission restriction objects and a plurality of transmission restriction cancellation objects, respectively.
Numbers registered as outgoing call barring numbers are not included in outgoing call barring numbers, and numbers registered as outgoing barring barring targets are not included in outgoing call barring number comparisons. Also, in this case,
When the control unit 11 serving as the transmission restriction control unit compares the number dialed from the analog terminal from the first digit of the dialed number as information relating to the transmission restriction target, the control unit 11 compares the transmission restriction release target number with the above number. If it matches the one in the registration table, it is excluded from the comparison target and the comparison is performed again with the remaining numbers.

Next, a specific operation of the transmission restriction control means of this embodiment will be described based on an operation example shown in FIG. In this case, the registration table shown in FIG. 3 is used as the setting condition. First, since “184” (specified number for non-caller ID), which is a special number, is registered as a target for canceling the transmission restriction, “184” is removed from the comparison target, and then the remaining numbers are used. The comparison is performed again from the top of the removed state. At this time, since "0990" (designated number of a specific paid communication service) is registered as a transmission restriction target, a dial number from an analog terminal is a transmission restriction target. As a result, the dialed number is not transmitted as a transmission restriction target, and a busy tone is transmitted to the analog terminal side to notify the user of the fact.

Further, this terminal adapter device 1
Telephone 2 which is an analog terminal as a character string to be registered for outgoing call restriction target and outgoing call restriction release target in the registration table
An arbitrary number registration determination means is provided which enables a specific number of digits of the PB signal of the call information from the telephone number to correspond to an arbitrary dial number.

More specifically, the registration table shown in FIG. 5 sets an arbitrary number as the transmission restriction release target as registration data of the transmission restriction target and the transmission restriction release target as registration data. In this case, the function number "*" of the PB signal is used for the arbitrary number registration, and for example, "18 *" and "00 **" are added as the transmission restriction release registration data.
In other words, this "*" indicates that any number from 1 to 0 is applied. In this example, when "18 *" is dialed, the three digits are removed from the comparison target as the transmission restriction release target, Thereafter, comparison is performed again from the beginning of the removed state with the remaining numbers. As described above, in the registration table shown in FIG.
And "186" need to be registered. According to the registration table shown in FIG. 5, a specific number of digits of the PB signal of the call information from the analog terminal can be dealt with any dial number. , "18 *" can be supported.

The specific operation of the above embodiment will be described based on an operation example shown in FIG. First, "18" shown in FIG.
When a dial number is originated with "4" at the beginning, the first "184" (designated number of which the caller ID is not notified) matches the "18 *" registered as the target for releasing the call regulation ("*"). "" Is an arbitrary number) and "184" are removed from the comparison target, and then the remaining numbers are compared again from the beginning of the removed state, at which time "008x" (other company designation number: "x") ("Means a specific number") matches "00 **" registered as an outgoing call restriction cancellation target. Therefore, "008x" is further removed from the comparison target. The comparison is performed from the top of the removed state, where the remaining dial numbers "03-XXX-
Since “△△△” is registered as a call barring target, dial numbers from analog terminals are barred from dialing. As a result, the dialed number is not dialed as barring and is not sent to the analog terminal. Sends a busy tone to notify the user.

As described above, an arbitrary number can be specified.
When registering as an outgoing call restriction target and outgoing call restriction release target,
By specifying only a specific number of digits, registration is possible and usability is improved. Furthermore, by using the designation of an arbitrary number in combination with the registration of the transmission restriction target and the transmission restriction release target, the specification can be flexibly performed, and the applicable range can be expanded. For example, when a special number (1XY system or the like) is designated as a transmission restriction target or a transmission restriction release target, if an arbitrary number (# or *) is set in the XY part, only one registration is required. Also,
The same applies to the case of designation of another business. For example, even for registration of 00XY, only one registration is required.

That is, conventionally, registration of an area code or the like is performed by one.
Although it was possible to register only one by one, it is also possible to specify for each range. For example, it is regulated by the regional group of 07X. It is possible to register several area codes (depending on the actual use). Similarly, it becomes possible to register a group of numbers including overseas calls. That is, for example, a certain digit of the area code is arbitrarily designated to restrict outgoing calls to a specific area, or the last digit of a subscriber number is designated to restrict outgoing calls to a plurality of numbers. This makes it possible to expand applications.

Therefore, according to the terminal adapter device 1 described above, the transmission restriction target and the transmission restriction release target are included in the registration table referred to by the transmission restriction control means. Then, as a character string to be registered in the registration table, a specific number of digits of a PB signal of call information from an existing analog terminal such as a telephone connected to an analog port, which is an R point interface, is set to an arbitrary dial number. Outgoing call barring control allows you to easily control outgoing calls when assigning a special number or carrier before the outgoing call number, and also register outgoing call numbers (outgoing call barring numbers) that have been excluded from outgoing call barring. It becomes possible.

In the above-mentioned example, the registration data for the transmission restriction release target is set to be compatible with any dial number having a specific number of digits. However, it is needless to say that the registration data for the transmission restriction target may be used. Needless to say.

[0030]

The present invention is embodied as in the above-described embodiment. When a special number, a communication carrier or the like is added before a calling number, the calling can be easily regulated and excluded from the subject of the calling regulation. The registered calling number (calling restriction release number) can also be registered.
