Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a selective call termination control method in a device connected to a subscriber line of a telephone network and accommodating a plurality of terminals.

[Conventional technology]

A "home telephone" is a telephone device that is connected to a telephone subscriber line and accommodates multiple terminals (8) If a party wishes to communicate with a specific telephone among the telephones accommodated in the home telephone, the caller must Dial the number of the home telephone.The home telephone that receives the call from the telephone network first rings all the multiple telephones accommodated by the home telephone.At this point, it is unknown who is being called, so A person near the home telephone responds, learns by communication with the caller which specific terminal the caller desires, and then calls the terminal to communicate with the caller.

[Problems to be solved by the invention]

Therefore, when you want to communicate with a specific terminal among multiple terminals housed in a device such as a home telephone, manual intervention is always required, and there is a problem in that it is impossible to directly call and communicate with that terminal. There was a point.

The purpose of the present invention is to solve the above-mentioned problems, and to provide a system that allows a caller to call a desired terminal and communicate with the terminal without any human intervention on the receiving side, that is, a system that enables communication with the terminal at the subscriber's premises. The purpose is to provide a mini PBX-like system with a dial-in function.

[Means for solving problems]

According to the present invention, the above problem can be solved by accommodating a telephone subscriber line in a telephone device accommodating a plurality of terminals assigned sub-numbers, and receiving and receiving a calling signal from the telephone subscriber line. The 1 6 II z receiver that responds to has a part, and the 16
The response from the Hz receiver activates the announcement machine and sends a talkie to the caller. It has an automatic call reception unit that prompts the user to dial a sub-number, and a selection signal translation unit that is connected to the automatic call reception unit through a call path, receives the sub-number sent from the caller, and sends out the sub-number. The sub-number receiving unit is connected to the sub-number receiving unit through a call path, and upon receiving the sub-number sent from the sub-number receiving unit, connects the terminal with the corresponding sub-number to the call path and sends out a calling signal. In addition, the non-applicable terminal is equipped with a connection section that sends a talkie to notify that the telephone subscriber line is busy, and the telephone line is connected via the automatic call reception section, sub-number reception section, and connection section. This problem is solved by a selective incoming call control method that connects to the terminal specified by the caller.

[For production]

A telephone device that accommodates a plurality of terminals assigned sub-numbers and is connected to a telephone subscriber line automatically responds to a calling signal from the telephone subscriber line and operates an announcement machine to call the f3 party. The system plays a talkie prompting the caller to dial the desired sub-number, receives the sub-number sent by the caller, selects the terminal with the corresponding sub-number, and calls.
By the caller's dial operation, the caller's desired terminal is called without any human intervention on the receiving side.

00 through a telephone subscriber line 4. The selective call reception control device 100 is composed of an automatic call reception section 1, a sub number reception section 2, and a connection section 3.
It accommodates n terminals numbered with sub numbers No, n.

Hereinafter, the general operation of selective call termination control will be explained assuming that the caller wants to communicate with a specific terminal accommodated in the selective call termination control device 100, for example, No., k (1≦ and ≦n).
(See sequence diagram in Figure 2).

1) When a caller (not shown) dials the telephone number assigned to the selective call control device 100, a calling signal is sent to the selective call control device 100 from the telephone office.

2) The automatic call receiving unit l in the selective call receiving control device 100 receives the calling signal and responds to it (as a result, the caller and the automatic call receiving unit enter a communication state), and at the same time, the automatic call receiving unit l makes an announcement within the automatic call receiving unit. The machine is operated, and when the automatic call reception section answers, the caller receives Talkie-A via the set communication path and prompts the caller to dial the sub-number of the desired terminal. During this time, Talkie-E is sent to each terminal indicating that the subscriber line is in use.

3) After the caller (not shown) receives the talkie-A,
PB the sub number you want (here, No, k)
Dial by signal (Note: PB signal is required as DP double signal path cannot be passed).

4) The sub number is received by the sub number receiving unit 2 after passing through the automatic call receiving unit l in the selective call receiving control device 100, and the sub number N is sent from the sub number receiving unit 2 to the connection unit 3.
00k is notified.

The connection unit 3 connects to the terminal corresponding to the notified sub number No. k, and sends a call signal to the terminal. During this time, a talkie-C message indicating that terminal No. k is being called is sent to the caller.

5) Upon receiving the response from the terminal No., the connection unit 3 connects the path between the caller and the terminal No., and enables communication between the two.

6) If a response from the terminal No. is not received for a certain period of time, the connection unit 3 receives a predetermined home phone (here, the home phone designated in the storage means in the connection unit)
The connection is then switched to the terminal assigned the sub-number 01), and the caller receives Talkie-D indicating that the switch has been made, and at the same time sends a calling signal to the telephone No. 1.

As long as the home telephone does not answer, the connection unit 3 continues to send out the calling signal until the caller disconnects.

As described above, in the method of the present invention, by responding to a call from the telephone network within the selective call termination control device, a communication channel path between the caller and the selective call termination control device is first set, and the call path is established through the path. A sub-number assigned to a desired terminal is received from the caller in a PB signal, a call is made to the terminal from the selective call termination control device, and a call is made between the caller and the caller within the selective call termination control device based on the response from the terminal. The path between the desired terminals is connected to enable communication between the two. Therefore, the caller can communicate with the terminal he or she desires without any human intervention.

Next, the operation of the selective call termination control device 100 will be explained in more detail with reference to the block diagram of FIG.
