JPS6010956A - Control system to special incoming service subscriber - Google Patents

Abstract

PURPOSE:To improve the service to a caller by allowing an operator to intervene all calls to a special incoming subscriber, and controlling the incoming to the special incoming subscriber by the operation of the operator to identify idle/ busy state of the special incoming subscriber. CONSTITUTION:When a caller A makes dialling calling a special incoming service subscriber B, its caller information is stored in a storage block CCB for call control in a storage device MM by a processor CPR via an incoming trunk ICT, and connected to the operator board OP via an outgoing trunk OGT. After the operator talks with the caller A, the operator discriminates by a conversion table that the caller A is to be allowed for incoming to the subscriber B, and operates an operating button HKB, then a processor detects it and informs the idle/busy state of the subscriber B through a dial tone DT and a busy tone BT or through lamp display provided on the operation board to the operator.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a subscriber control system in which the idle state of a special call service subscriber can be constantly identified from an operator's console.

(2) Background of the Technology A special incoming call service subscriber is a subscriber who receives incoming calls with a service different from that of a normal telephone, such as a telephone in a president's office connected to a private branch exchange.

In the conventional control system shown in FIG. 1, a special termination service subscriber (hereinafter abbreviated as 5VIS subscriber)
R and a storage device MM are provided to perform predetermined control. In other words, regular subscriber A on an outside line or extension is 5vis subscriber B.
When a call is made to 5vrs subscriber B, Prosensor CPR knows that the call is to 5vrs subscriber B by knowing the information in the storage device MM that is registered in advance, so it immediately controls the call to not be made.

(3) Prior Art and Problems Conventionally, when 5VIS subscriber B is busy, the call cannot be received and only the busy tone is heard. Caller A requests an incoming connection to 5vrs subscriber B in order to receive a call directly to the operator console OP when it is empty. Since the operator does not clearly know whether 5VIS subscriber B is blocked and whether incoming calls are allowed, caller A
5VIS subscriber B attempts to inquire as to whether or not the incoming call from A can be connected. At this time, 5V
When IS subscriber B takes the telephone off-hook, the connection between caller A and operator console OP is forcibly disconnected.

This is because the storage device MM stores that there was a call from A to B. A busy tone is connected to both A and the operator.

For A, when he suddenly hears a busy tone after making a request to the operator, he has no idea why. As described above, there was a drawback that the service for callers was extremely poor. In order for operators to provide services efficiently,
I would like to check the status of the called person, but there is no way to do so.

(4) Object of the Invention An object of the present invention is to improve the above-mentioned drawbacks and to provide a subscriber control system that allows the idle status of 5VIS subscribers to be constantly identified from the operator's console.

(5) Structure of the Invention The structure of the present invention to achieve the above-mentioned object is, in a control method for a special service subscriber connected to a network controlled by a call processing processor and a storage device,
The storage device is equipped with a memory block for call control, and a function button provided on the operator's desk that can obtain a signal equivalent to funking, so that incoming calls to the special service subscriber are always transferred to the operator's desk, and Information regarding the incoming call is recorded in the call control memory block 1. (a) The operator knows the status of the called party by operating the function button.

(6) Embodiment of the Invention FIG. 2 is a diagram showing the configuration of an embodiment of the invention, and corresponds to FIG. 1. In FIG. 2, CCB indicates a call control memory block, which is provided in the memory device MM and stores information regarding the calling subscriber, called subscriber, and operator console.

HKB is a function button provided on the operator's desk OP, and when operated, it gives a signal equivalent to a function button to the processor CPH. DT is a dial tone generator, BT is a busy tone generator, and WT is a waiting tone generator. Caller A is 5
When a predetermined number is dialed to make an incoming call to VIS subscriber B, the call information arrives via the large trunk ICT, is stored in the memory block CCB in the memory device MM by the processor CPR, and is simultaneously sent to the outgoing trunk. O.C.
Connected to the operator's console via T. This connection is 5v
This is done regardless of whether rs subscriber B is unavailable. The operator learns from the call that the call is from A to 5vrs subscriber B, and then determines from a comparison table that A is allowed to receive the call from B. He operates the operation button HKB and sends the call to the exchange. Sends a signal equivalent to hooking. Processor C
When PR detects this, it temporarily suspends the connection between A and the operation console, and responds differently depending on the state of B. If B is empty, a dialing tone is sent from the DT to the operating console OP, and a waiting tone is sent from the WT to A, causing it to stand by.

If B is occupied, a busy tone is sent from the BT to the console OP, and a waiting tone is sent from the WT to A.

The operator notifies A whether connection to B is possible or not, and when the connection is possible, operates the transfer key on the operation console and sends a transfer signal to the exchange, thereby placing the A-B line in the network NW on hold. A calling signal is sent to B, and a ringing tone is sent to A. When B goes off-hook, he can talk to A. Figure 3 A, B.

C and D show this state.

If the connection is not established, the connection with A is released. Figure 4A,
B is a diagram showing changes from when 5VIS subscriber B was in a blocked state.

In the above explanation, when the operator learns of the idle state of 5vrs subscriber B, the operator identifies it by sound, but the operator can also identify it by providing a lamp on the operation console and displaying the change in the line signal. In this case, since the communication path between A and the operator is not temporarily disconnected, the service is further improved.

(7) Effects of the Invention In this way, according to the present invention, the operator intervenes in all calls made to 5VIS subscribers, and the incoming calls to 5VIS are controlled by the operator's operations, making it possible to talk to the operator. There is no sudden change to the busy tone, which greatly improves service.
