JPH02274157A - Call charge real time recognition system - Google Patents

Abstract

PURPOSE:To recognize an accurate charge in a real time by making call charge information on the exchange side and displaying it directly on a call charge display device in a subscriber's equipment. CONSTITUTION:When a subscriber makes a call, an exchange connects the call via a channel device 6 and the recording of the charge to the subscriber is controlled by a central controller 8 and stored in a storage device 9. When the central controller 8 identifies the calling subscriber to be a subscriber desired for call charge real time recognition, it is recorded and the controller 8 controls a channel controller 7 to send the call charge information ABC to a signal device 10 and the channel device 6 is simultaneously controlled to interrupt the connection between the subscriber circuit 4 and a trunk 5 for a short time and the call charge information ABC is outputted from the signal device 10 to the subscriber line as the combination of frequencies in a specific frequency group. Thus, the subscriber can recognize the call charge up to now.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a system for instantly knowing call charges.

[Conventional technology]

The conventional call charge instant notification system places a home charge display in the subscriber's premises, sends AC pulses outside the call band for a fixed period of time to the subscriber's line for each charging unit time, and operates the subscriber's premises frequency meter. It displayed the number of calls or charges.

[Problem to be solved by the invention]

The conventional call charge instant notification method described above displays charges based on the number of calls, so the relationship between the number of calls and the actual call charge must always be constant. Even if you make a call, there is a problem that the display will be inaccurate if the call fee changes depending on which of multiple carriers you use, or the call fee per hour or frequency is not proportional to the time.

The purpose of the present invention is to create call charge information on the exchange side and display it directly on the call charge display device in the subscriber's premises, so that accurate charges can be displayed in real time regardless of the difference in carrier or charge structure. The purpose of the present invention is to provide a method for instantly informing you of call charges.

[Means to solve the problem]

The call charge instant notification system of the present invention is a call charge instant notification method of a telephone exchange system, in which the subscriber side is provided with a demultiplexer that demultiplexes a specific frequency group from a received frequency band and receives the specific frequency group. The system is equipped with a call charge display device that visually displays call charges, and the exchange has a function of periodically outputting the call charges to the subscriber line as a combination of frequencies in the specific frequency group.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

On the subscriber side, there are a telephone 1, a branching filter 2 that separates a specific frequency group from the received frequency band, and a call charge display device 3 that receives the specific frequency group and visually displays the call charge. . On the exchange side, there is a subscriber circuit 4 that connects to equipment on the subscriber side, a communication path device 6 that connects the subscriber circuit 4 with a trunk 5 for connecting to other stations, and a communication path system that controls the communication path system. A communication path control device 7, a central control device 8 that controls the entire exchange, a storage device 9 that stores information for controlling the central control device 8 and subscriber billing information, and a central control device 8.
There is a signal device 10 which has a function of receiving information from the network and intermittently outputting the call charge as a combination of frequencies in a specific frequency group to the subscriber line via the communication path device 6.

When a subscriber makes a call, the exchange connects the subscriber circuit 4 and the trunk 5 via the communication path device 6 in accordance with the dial number sent from the telephone set 1, and allows a call to be made with another station.

At this time, records of charges to subscribers are recorded in the storage device 9 under the control of the central control device 8.

Here, when the central control device 8 identifies the subscriber who has just made the call as a subscriber who wishes to know the call charges immediately, the central control device 8 records the billing record for the subscriber in the storage device 9, and also records the charge to the subscriber in the storage device 9. 7 to send call charge information A, B, and C to the signal device 10, and at the same time control the call path device 6 to interrupt the connection between the subscriber circuit 11 and 1-rank 5 for a short time; Call charge information A, B, and C are output from the signal device 10 to the subscriber line as a combination of frequencies in a specific frequency group. Call charge information A and B sent by the signal device 10.

C is received by the duplexer 2, and only the call charge information A and BC reach the call charge display device 3. Call charge display device 3
displays the call charge information A, B, and C in real time. The subscriber who made the call can know the current call charges by looking at this display. The call charge display device 3 displays this display as the next call charge. ! Hold until A, B, and C are received.

〔Effect of the invention〕

As explained above, the present invention creates call charge information on the exchange side and displays it directly on the call charge display device in the subscriber's premises, thereby ensuring accuracy regardless of the difference in carrier or charge structure. It has the effect of being able to know the price in real time.
