Abstract

PURPOSE:To attain the communication with a desired caller by a called party by storing in advance a subscriber number allowing an incoming reply and accepting an incoming call only from a caller with the same number as the subscriber number. CONSTITUTION:n-Set of subscriber number storage sections 5-1 to 5-n storing plural sender subscriber numbers accepting an incoming call as one set are provided. A subscriber number detection section 4 detects a subscriber number included in an incoming signal and a retrieval section 7 retrieves a subscriber number storage section selected by a selection section 6. Then when the same subscriber number as the subscriber number detected by the subscriber number detection section 4 is stored, the result is informed to a main control section 8 and the succeeding connection control procedure is executed by a network control section(NCN) 2. Thus, a party desiring an incoming call is selected freely and replied.

Description

Detailed Description of the Invention [Invention 1] (Industrial Application Field) The present invention provides a method for receiving a line connected to a FiI network that is capable of adding a calling subscriber number to an incoming signal. This relates to terminal devices.

(Prior Art) Receiving terminal devices that are connected to a line network and are used include lightning devices and facsimile devices.

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

By the way, the option of rejecting a call from a network if you do not want to answer the call, and answering only if the call is from a person you wish to receive, would be very convenient if you had the ability to do so. .

(Problem to be Solved by the Invention) However, in the conventional public telephone line network or dedicated line network, the subscriber number of the caller is not notified to the called party, so it is difficult for the called party to identify the caller. Therefore, there was a problem in that it was not possible to realize the selection response function as described above.

An object of the present invention is to provide a line terminal device that can select and respond to only desired parties.

[Structure 1 of the Invention (Means for Solving the Problems) The present invention focuses on the fact that in l5DN (integrated digital service network), it is possible to add a calling subscriber number to an incoming signal, and stores a plurality of subscriber numbers. storage means; detection means for detecting a calling subscriber number included in the incoming signal;
Incoming call response control means that verifies whether or not the same subscriber number as the detected calling subscriber number is stored in the storage means, and permits reception of the incoming call only when it is stored. be done.

(Operation) If the same subscriber number as the optical source account number inserted in the incoming signal is stored, the incoming call is permitted; if the same subscriber number is not stored, the incoming call is not permitted.

Therefore, if you memorize the subscriber number that is permitted to answer incoming calls in advance, only incoming calls from the caller with the same number as this subscriber number will be accepted, and the called party will be able to communicate with the desired caller. It is possible to communicate only with

(Embodiment) FIG. 1 is a block diagram showing an embodiment of the present invention.
Network control unit (NC (J > 2, communication via NCU 2 (communication in the case of a phone call, transmission and reception of image signals in the case of a facsimile bag) that executes the line connection procedure with the S D N81 a subscriber number detection unit 4 that detects whether or not the originating subscriber number is included in the incoming call signal, and if so, what kind of M''t it is;
0 set of subscriber number storage units 5-1 to 5-n that store a plurality of originating subscriber numbers that are permitted to receive (m) as one set;
.

A selection section 6 selects one of the subscriber number storage sections 5-1 to 5-n, and a subscriber whose number is the same as the originating subscriber number detected by the subscriber number detection section 4 is selected by the selection section 6. A search unit 7 that searches whether the number is stored in any one of the number storage units 5-1 to 5-n, and a main control unit that permits reception of M1g according to the search result of the search unit 7. It is equipped with 8.

FIG. 2 is a flowchart showing the operation when a call is received in the above configuration.

First, when the NCU 2 receives an incoming signal from the 15DN line 1, it transfers this incoming signal to the subscriber number detection unit 4 according to instructions from the main control unit 8.

Therefore, the subscriber number detection unit 4 detects whether or not the originating subscriber number is included in the incoming signal (step 201).
), if it is not included, indicate that in the main and subtext? Notify n department 8. In response, the main control unit 8 instructs the NCU 2 not to perform the subsequent connection control procedure for the incoming call. As a result, reception of incoming calls whose originating subscriber number is unknown is not permitted.

On the other hand, if the incoming signal contains the optical source subscriber number, the subscriber number detection unit 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 the subscriber number storage unit 5-1 selected by the selection unit 6.
It is checked whether the same subscriber number as the subscriber number detected by the subscriber number detecting section 4 is stored in the subscriber number detecting section 4 (steps 203 and 204). As a result, if the same subscriber number is stored, the main control unit 8 is notified of the result and the NC1J2 is caused to execute the subsequent connection control procedure.

As a result, incoming calls from the caller will be accepted normally (
Step 205). However, if the same subscriber number is not stored, this will be notified to the main control unit 8 and the reception of the incoming call will not be permitted.

Therefore, depending on the combination of the contents stored in the subscriber number storage sections 5-1 to 5-n and the selection contents of the selection section 6, it is possible to select various types of optical sources that respond to incoming calls.

For example, in the subscriber number storage units 5-1 to 5-n, company A, company B
The subscriber numbers of Company E, .
If you select these sequentially over an hourly period, only incoming calls from company A will be received in the first hour, and calls from company B will be selected in the next hour.
This allows for a usage pattern in which only incoming calls from companies are accepted.

Such usage patterns can be realized in various ways depending on the user.

For example, in a typical household, only the police, fire department, and relatives will accept calls late at night. This will solve the problem of sleep disturbance caused by prank calls and the like.

Additionally, news outlets such as Lean will only accept incoming calls from subscriber numbers with a specific area code. This makes it possible to collect information by region.

In this way, according to this embodiment, it is possible to select and respond to only desired parties.

Note that the subscriber number storage units 5-1 to 5-n store the subscriber numbers of group w11 as one set, but for small-scale users who receive a small number of calls, each storage unit stores one subscriber number. It is also possible to store only the following information. Alternatively, only one set of subscriber number storage units 5-1 to 5-n may be provided, and the stored contents may be replaced manually or automatically to accept incoming calls from only desired parties. In this case, the selection section becomes unnecessary. Furthermore, this defense is applicable not only to telephones and facsimile machines, but also to various communication terminal devices that utilize 15DN.

[Effects of the Invention] As explained above, according to the present invention, it is possible to freely select and respond to a desired party. As a result,
This has the effect of making it possible to use it in a variety of ways, and expanding its capabilities as a receiving terminal device.
