Abstract

PURPOSE:To allow a public telephone user to know a unit talking charge before the talking by providing a means deciding a charging index by a received called party number at calling from a public telephone set. CONSTITUTION:When a caller dials a callee number from a public telephone set 1, the number is received by an outgoing register trunk 4 and the result is sent to a central processing unit 7 via a channel controller 6. The unit 7 reads a charge index data by talking line from a main memory 8 to decide the charging index of a talking party corresponding to the callee number, the charging index information is sent to a voice notifying device 5 via the controller 6, to disconnect a trunk 4 connected to the telephone set 1 thereby reconnecting the device 5. When the device 5 is connected to the telephone set 1, the talking unit charge is informed in voice to the caller based on the charging index information received before.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a charge notification system that provides unit call charge service prior to making a call in a storage program control type telephone exchange that accommodates public telephones. .

[Conventional technology]

Conventionally, this type of charge notification system notifies the user of the charge for the call at the end of the call, but there has not been a service that notifies the user of the unit call charge for the call to be made prior to the call.

[Problem that the invention seeks to solve]

With the conventional charge notification method described above, when making a long-distance call from a public telephone, if the user wants to know how much the call will cost, the user can refer to the charge list corresponding to the call distance listed in the telephone directory. The problem was that I had to look at it and calculate it.

[Means for solving problems]

The charge notification method according to the present invention determines a charge index based on the received pseudo-called party number when making a call from a public telephone, and notifies the caller of the unit call charge based on the determined charge index prior to the call. It is something to do.

[Effect]

This invention allows public telephone users to know the unit call charge before making a call.

〔Example〕

The figure is a block diagram of a telephone exchange showing an embodiment of the charge notification method according to the present invention. In the figure, 1 is a public telephone, 2 is a network, 3 is an outgoing trunk, 4 is a calling register trunk that receives dials from callers, and 5 is a billing unit sent from the central processing unit below. A voice notification device that receives index information via the communication path control device described below, converts it into voice, and notifies the caller; 6 is the public telephone 1, the communication path network 2, the outgoing trunk 3, and the calling register trunk 4; and a function to monitor the status of the voice notification device 5 and send information to the central processing unit described below, and information from the central processing unit described below to the public telephone 1, communication path network 2, outgoing trunk 3, and outgoing register trunk 4. and voice notification device 5
The communication path control device T, which has the function of controlling Receive the dialed number of the called party, read out the call destination charging index date J1 from the main memory below,
a central processing unit having a function of determining a charging index for the call destination corresponding to the called party number, and a function of transmitting the determined charging index information to the voice notification device 5 via the call path control device 6; Reference numeral 8 denotes a main memory for temporarily storing programs, call destination charging index data, and information being processed.

Next, the operation of the charge notification method with the above configuration will be explained, for example, the operation of making a call from the public telephone 1 to a subscriber of another station. First, when the public telephone 1 makes a call, the call path control device 6 detects the call and sends call detection information and caller accommodation location information to the central processing bag [7]. Therefore, the central processing unit 7 receives these information, controls the communication path control device 6, and connects the public telephone 1 and the calling register trunk 4. Subsequently, when the calling party dials the number of the called party, a call is made, received by the calling register trunk 4, and sent to the central processing unit 7 via the channel control device g6. Therefore, when the central processing unit 7 receives the called party number, it reads out the charging index data for each call destination from the main memory 8, determines all the charging index data for the call destination corresponding to the called party number, and then sends the call path control device 6 The determined billing index information is sent to the voice notification device 5 via the voice notification device 5, and the call path control device 6 is controlled to disconnect the calling register trunk 4 connected to the public telephone 1 and connect the voice notification device 45 with the voice notification device 45. Change the connection. Therefore, when this voice notification device α5 is connected to the public telephone 1, the previously received billing index '
Based on the RFT report, the caller is notified by voice of the unit call charge for the call to be made. And the central processing unit 7
After a certain period of time, the communication path 1↑] takes control of the control device t6 and releases the public? & Phone 1 and voice notification/cheer (45 connection tone released,
After changing the connection with the outgoing trunk 3, all other exchanges are activated, and the normal relay exchange connection fl is performed to connect to the called party.

〔Effect of the invention〕

As explained in detail above, according to the charge notification method according to the present invention, the charging index is determined from the called party number and the result is notified to the caller prior to the call, so the public telephone user can This has advantages such as being able to know the unit call charge before making a call, and being able to use public telephone services as well.
