JPS58184860A - Incoming connecting method of specific subscriber - Google Patents

Abstract

PURPOSE:To select the incoming connection with the will of a called party, by forming the connection only when a specific registration number of the called party is coincident with the special number of a caller. CONSTITUTION:When the called party SUB-A allows the connection of a specific incoming subscriber only and does not want other incoming connections, the SUB-A registrates a special number for the incoming connection approval to a storage device M in advance with dial operation. Only when the special number of a caller is coincident with the said special number of approval of incoming calls, the connection with the SUB-A is formed. If dissident, the incoming call is connected to an announcement trunk ANT.

Description

[Detailed Description of the Invention] The present invention relates to a method for automatically connecting an incoming call to a specified subscriber, and the called subscriber is authorized in 4. , relates to an incoming call connection method for a specific subscriber that can refuse all other incoming call connections.

In the conventional specific subscriber terminating connection method, for example, as shown in FIG. If you request the relay stand operator ATT to register to reject incoming calls,
The relay stand operator accesses the storage memory gc@M via the control device (:0).
I had registered this fact. Thereby, trunk TRK
-A, TRK-B, and #177 [1 entry SU B
- All incoming connections from B were disabled. Therefore, when there is a call from the office, the receiving register I)L indicates that the receiving address is 42 digits, but the control device CC and the storage device M determine the number of called subscribers S U for all the called subscribers.
Announcement Drunk ANT was used to inform that B-A was refusing. In addition, switch frame SW
Links (T) to ■ indicate the connection path 1 in the case of a C call, an incoming call, or an announcement. In short, called subscriber 8 T
Approval if it is a specific incoming subscriber identified by JB-A! The drawback was that even if you wanted $, there was no actual loss of connection.

The purpose of the present invention is to realize a 2-an incoming call rate by pre-registering a special number for authorization of incoming call connection by the called subscriber's dial operation, and to make other incoming call connections impossible for a specific subscriber. Incoming call connection method 1r is provided. Will this prevent malicious calls in which only calling subscribers who know the special number registration can receive calls? It can be realized.

The method is that if a calling subscriber only approves the connection of a certain called subscriber and does not want to receive any other calls, the called subscriber must have a 'F special number is dialed to the storage device, and when connecting an incoming call, only if the calling subscriber's special number matches the special number of the Sage town that received the previous call, the caller is connected to the calling subscriber. , and the called subscriber, and if there is a mismatch, the incoming call is connected to the announce trunk or the like 111.

Next, an embodiment of the present invention will be described with reference to FIG.

FIG. 2 is a relay system diagram of an exchange, which explains the present invention in detail. First, the called subscriber STJ B-A listens to the dial tone from the originating register OR by a known method, and receives the special registration number for the Gofu Shinden 1 continuation material heard through the link of the frame. The 0 dialing register OR registers this news in the storage device M via the control i-electronic CC.

Now, when there is an incoming call to station M calling subscriber and trunk TR via -A, reception register I I+ is sent via link ■.
8UB-A receives the subscriber number of the called subscriber 8UB-A. Control length [CC translated this...1 When recognizing that the incoming connection authorization has been registered in memory Wf1M, TR,
- Sends a service set tone to A. Further, after trunk TRK-A listens, the caller dials the @taste code for authorization of the incoming connection. Receive register IR
receives all of this and transfers this information N to the control device CC.

The control device CC first identifies this special number to the called subscriber 8UB-.
It is determined whether the number matches the incoming call authorization registration number registered by A by 4 via the storage device Mi. If the special number from trunk TRK-A and the incoming call authorization registration number of SUB-A match, the control device CC translates it into the information necessary for connection and sends 8 U by a known method.
H-A-SW link - TltK-A is connected, a communication path is formed with this route, and 5UB-A and TltK-A are connected.
It becomes possible to communicate with the transmitter via RK-A.

10,000, similar to the above, the trunk TRK-H receives a special number from the receiving register IR via the link (color) and also the incoming trunk TRK-B.

+4 As explained above, if a called subscriber wants to connect to a particular incoming call Vc Zenuma or any other incoming calls, the called subscriber can register this registered number and the calling party by registering a special number. A connection can be established between the calling subscriber and the called subscriber only when the special numbers of the calling subscriber match.
The called subscriber can choose from 18 incoming connections according to his or her will, and is also effective in preventing malicious calls.

Claims (1)

[Claims] 9.2 In the incoming call method of an automatic telephone interception machine, the called subscriber wants to continue with only one calling subscriber and refuses all other calls. Dial the phone number for authorization of incoming connection, and record it on the device, and when connecting the incoming call, the calling subscriber's '4 number' should be the first 4.
The connection between the calling subscriber and the called subscriber is established only if the numbers match the numbers for telephone connection authorization, and if they do not match, the incoming call is connected to the announce trunk, etc.).
