Description

Description: Object of the Invention (Industrial application field) The present invention relates to a line receiving terminal device connected to a line network capable of adding a caller's subscriber number to an incoming signal. Things.

(Related Art) As a receiving terminal device used by being connected to a circuit network,
There are telephones and facsimile machines.

The line network to which these receiving terminal devices are connected is generally a public telephone line network or a dedicated line network.

By the way, if there is a selective response function that rejects an incoming call from the line network if it is not desired to respond and rejects the incoming call only if the incoming call is desired, it is very convenient.

(Problems to be Solved by the Invention) However, in the conventional public telephone line network or leased line network, the calling subscriber number is not notified to the called side.
The called party cannot identify the caller,
There is a problem that the selection response function as described above cannot be realized.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a line receiving terminal device capable of selecting and responding only to a desired partner and enabling various usage modes.

[Constitution of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention relates to a line receiving terminal device connected to an integrated digital service network, comprising: Storage means for storing a subscriber number; selecting means for selecting at least one source subscriber number from a plurality of source subscriber numbers stored in the storage means; Detecting means for detecting a source subscriber number included in an incoming signal transmitted from the integrated digital service network; and storing the source subscriber number detected by the detecting means in the storage means selected by the selecting means. Comparing means for comparing with the stored source subscriber number; and a source subscriber number detected by the detecting means from a comparison result by the comparing means. Incoming call response control means for permitting reception of an incoming call corresponding to the caller's subscriber number only when the call coincides with one of the caller's subscriber numbers stored in the storage means selected by the selecting means. It is characterized by the following.

(Operation) A plurality of source subscriber numbers permitted to accept the incoming call are stored in the storage means, and one or more desired source numbers of the plurality of source subscriber numbers stored in the storage means are stored. The subscriber number is selected by the selection means.

Then, at the time of an incoming call from the integrated digital service network, a source subscriber number included in an incoming signal transmitted from the integrated digital service network is detected by a detecting means. Only when it matches any one of the source subscriber numbers selected by the selection means, acceptance of an incoming call corresponding to the source subscriber number is permitted.

According to such a configuration, it is possible to freely select and respond to a plurality of parties desiring to receive an incoming call, and it is possible to provide a line receiving terminal device that can be used in various ways.

FIG. 1 is a block diagram showing one embodiment of the present invention.
A network control unit (NCU) 2 that executes a line connection procedure with the ISDN line 1 and communicates via the NCU 2 (a telephone call,
A communication unit 3 for performing transmission / reception of image signals in the case of a facsimile apparatus); determines whether or not the calling subscriber number is included in the incoming call signal; and if so, what kind of number is. A subscriber number detecting section 4 for detecting, n sets of subscriber number storing sections 5-1 to 5-n storing a plurality of source subscriber numbers for permitting reception of an incoming call as one set, and this subscriber number storing section A selection unit 6 for selecting one of 5-1 to 5-n; a subscriber number storage unit 5-1 selected by the selection unit 6 with the same number as the source subscriber number detected by the subscriber number detection unit 4; ~ 5-
and a main control unit 8 for permitting reception of an incoming call according to the search result of the search unit 7.

FIG. 2 is a flowchart showing the operation at the time of an incoming call in the above configuration.

First, when NCU 2 receives an incoming signal from ISDN circuit 1, NCU 2 transfers this incoming signal to subscriber number detecting section 4 in accordance with an instruction from main control section 8. Therefore, the subscriber number detecting unit 4 detects whether or not the calling subscriber number is included in the incoming signal (step 201), and if not, notifies the main control unit 8 to that effect. On the other hand, the main control unit 8
Will not perform subsequent connection control procedures for incoming calls
Instruct NCU2. As a result, the reception of an incoming call whose source subscriber number is unknown is not permitted.

On the other hand, if the incoming call signal includes the caller's subscriber number, the subscriber number detector 4 detects the subscriber number (step 202) and transfers it to the search unit 7. The search unit 7 searches the subscriber number storage unit (for example, 5-1) selected by the selection unit 6, and searches for the subscriber number storage unit 5.
It is checked whether or not the same subscriber number as the subscriber number detected by the subscriber number detector 4 is stored at -1 (steps 203 and 204). As a result, if the same subscriber number is stored, the result is notified to the main control unit 8, and the NCU 2 executes the subsequent connection control procedure. As a result, the incoming call from the source is normally accepted (step 205). But,
If the same subscriber number is not stored, this is notified to the main control unit 8 and the reception of the incoming call is not permitted.

Therefore, it is possible to select a source that responds to the incoming call in various forms according to a combination of the storage contents of the subscriber number storage units 5-1 to 5-n and the selection contents of the selection unit 6.

For example, the subscriber number storage units 5-1 to 5-n store company A, B
,... E, the subscriber numbers are stored.
If you select them sequentially in units of time, the first one
In the time, only the incoming call from the company A can be accepted, and in the next hour, only the incoming call from the company B can be accepted.

Such a use form can be realized in various forms by the user.

For example, in general households, late-night calls from police, fire and relatives are accepted. As a result, it is possible to solve sleep disturbance caused by a prank call or the like. In addition, news organizations accept only incoming calls of subscriber numbers having a specific area code set. This makes it possible to collect information by area.

As described above, according to the present embodiment, it is possible to select and respond to only a desired partner.

In the subscriber number storage units 5-1 to 5-n, a plurality of sets of subscriber numbers are stored as one set. For a small user having a small number of incoming calls, one subscriber number is stored in each storage unit. Only the information may be stored. Also, the subscriber number storage units 5-1-0 to 5-n may be configured as only one set, and the stored contents may be replaced manually or automatically to receive an incoming call of only a desired party. In this case, the selection unit becomes unnecessary. Further, the present invention is not limited to a telephone or a facsimile apparatus, but can be applied to various communication terminal apparatuses using ISDN.

[Effects of the Invention] As described above, according to the present invention, it is possible to freely select a person who wants to receive a call and respond. As a result, various usage forms are possible, and the function as the receiving terminal device can be expanded.
