Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a money fraud reporting system, and more particularly to a money fraud reporting system that notifies a private automatic branch exchange that the call charge exceeds a predetermined charge.

Conventionally, this type of money fraud reporting system involves transmitting a call time and minute forecast tone to the extension phone that is currently on the call at regular intervals, but with this method, the caller simply needs to know how long it has been since the start of the call. You can only know how much time has passed. For this reason, the amount of concession that the caller would like to know cannot be known unless the caller researches in advance the time that the call can be made at the basic rate in the area to which the call is made and calculates it by listening to the call time forecast tone. Furthermore, the call time and minute forecast sound can be heard even when it is not needed, and the transmission cycle of the call time and minute forecast sound cannot be changed according to the caller's will, which is extremely inconvenient. Furthermore, in the conventional system, it was impossible for subscribers to receive any kind of alarm service automatically from the switchboard or from the switchboard manager due to the extent of call charges accumulated over a long period of time. SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, it is an object of the present invention to provide a concession notification system in which allowable call charges are registered and the call charges are notified simply and accurately.

The present invention provides a private automatic branch exchange with means for accumulating call charges on an extension telephone and means for registering an arbitrary permissible call charge in the extension telephone in advance, so that the call charge on the extension telephone exceeds the allowable call charge. An object of the present invention is to provide a transfer amount notification system characterized in that when a transfer is made, a notification to that effect is sent to the extension telephone.

Next, an embodiment of the present invention in a horizontal automatic cross-side rock using an accumulation program control system will be described with reference to the drawings.

The drawing is a block diagram of an embodiment of the present invention.

In the drawing, an extension telephone A and a line-side warning trunk LWAT are connected to the line-side terminal of the switching network SW, and an outgoing register trunk ORT, an outgoing trunk OGT, and a trunk-side warning trunk TWAT are connected to the trunk side. and the switching network SW is connected to the communication path control circuit SPC.
It is assisted via a central control unit CC. A typewriter TTY and a memory control circuit MC are connected to the central control unit CC via a time control circuit TIM and a typewriter control circuit TTYC, respectively, and the memory control circuit MC includes a charge timer memory CGT and a charge warning memory. WAN and charge memory CHG
are connected in parallel. Closing and opening of channels connecting the line side and trunk side of the switching network SW described above are performed by commands from the central controller CC via the communication path control circuit SPC.

The charge warning memory WAN that stores allowable call charge information is configured to have a 16-bit memory corresponding to the line-side accommodation location information, and information can be written and erased by key operations on the typewriter TTY and from the extension telephone A. This is done by sending out dial information. To write the allowable call charges in the charge warning memory WAM corresponding to extension telephone A, enter the extension number and allowable call charge of extension telephone A in numbers from the typewriter TTY, and this information will be sent to the charge warning memory WAM via the typewriter control circuit TTYC. The extension number is then converted into address information of the charge warning memory WAN, and is sent to the memory control controller MC together with allowable call charge information to be written into the charge warning memory WAN. In addition, the hakama number ten dial information from extension telephone A is transmitted to central control unit C.
The dial information is sent to C, and the dial information is written as an allowable call charge, and the written allowable call charge is a value that is an integral multiple of the basic charge in Kenkin. Furthermore, charge memory CH
G stores accumulated call charge information configured to have a charge warning memory WAN and a 16-bit memory corresponding to line side storage location information, and updates to the charge memory CHG are performed for each call. The erasure is performed by operating the keys on the typewriter TTY. According to the money fraud reporting system of the present invention as described above, when extension telephone A makes a call, the call is detected by the central control unit CC via the communication path control circuit SPC, and the central control unit CC calls extension telephone A. The channel in the switching network SW connecting the originating register trunk ORT and the originating register trunk ORT is closed, and a dial tone is sent from the originating register trunk ORT.

If the dial information sent from extension telephone A is for a call to a pay area, central control center CC transmits the contents of charge warning memory WAN and charge memory CHG corresponding to extension telephone A through memory control circuit MC. and compare. Therefore, if the accumulated call charge exceeds the allowable call charge, the central control unit CC opens the channel connecting extension telephone A and calling register trunk ORT, and newly connects extension telephone A and trunk-side warning trunk TWAT. Close the channel and hear a warning tone on extension telephone A. From now on, when extension telephone A wants to make a call to a chargeable area, it can make the call again, send the samurai number + dial information, and erase the charge warning memory WAN or write a value larger than the accumulated call charge. It becomes possible. Further, when comparing the contents of the charge warning memory WAN and the charge memory CHG, if the cumulative call charge does not exceed the allowable call charge, the central control unit CC releases the extension telephone A and the calling register trunk ORT. , opens a new channel connecting extension telephone A and outgoing trunk OGT. Extension telephone A then hears the dial tone sent from the other party and is able to make a call. At this time, the central controller ℃C has a total of 40 bits of memory, 16 bits for storing line accommodation position information corresponding to the accommodation position status of the outgoing trunk OGT, and 24 bits for storing the hours, minutes, and seconds of the call start time. The line accommodation position information of the extension telephone A is written into the charge timer memory COT configured to have the following. and central control unit C
When C is notified of the start of a call between extension telephone A and the game party via the call control circuit SPC, the time control circuit TIM updates the time information of year, month, hour, minute, and second every second. ,
The minute and second information is extracted and written to the call time storage bit of the charge timer memory COT via the memory control circuit MC. Thereafter, the central controller CC calculates the elapsed call time every 4 seconds based on the call start time stored in the charge timer memory CGT and the time information of the time control circuit TIM, converts these into call charges, and stores them in the charge memory CHG. It is checked whether the sum with the stored cumulative call charge for extension telephone A matches the allowable call charge. If they match at this time, the central controller CC sends the line side warning trunk LW
Close the channel connecting the AT and the outgoing trunk OGT,
This channel is opened after 3 seconds, and by sending out a warning tone for 3 seconds, extension telephone A can know that the permissible call charge has been exceeded. When extension telephone A is restored and the call ends, central controller CC stores charge timer memory CO.
The charge memory CHG corresponding to extension telephone A is updated according to the contents of T and the call end time indicated by the time control circuit TIM, but this update is performed when the cumulative call charge that has not yet exceeded the allowable call charge just exceeds the allowable call charge. , the central controller CC is the typewriter control circuit TTY
The extension number, accumulated call charge, and allowable call charge of extension telephone A are typed out via C, and the information is also provided to the switchboard manager. In the above example, if the extension telephone makes a call and the allowable call charge is exceeded, the trunk side
Although a warning trunk is connected in this embodiment, a busy tone trunk or an announcement trunk may be used, or a warning trunk may be connected for a certain period of time and then connected to an outgoing trunk to enable outgoing calls. In addition, in the above embodiment, when the allowable call charge is exceeded at the end of the call, only a message is displayed on the typewriter, but it would be more effective if the extension telephone was called again and a warning announcement was sent out on the announcement trunk. . Furthermore, in the above embodiment,
During a call, a warning tone is heard for a certain period of time only when the sum of the accumulated call charge and the call charge calculated during the call matches the allowable call charge, but if the call charge exceeds the allowable call charge. A warning sound may be heard every time the value becomes an integer multiple. Furthermore, in the above embodiment, the charge warning memory and charge memory are configured to correspond to extension telephones, but the charge warning memory and charge memory are configured to correspond to extension telephone groups, that is, to correspond to line accommodation position information having the representative number of the extension telephone group. By configuring the memory, it is possible to provide services similar to those of the above embodiments to extension telephones belonging to an extension telephone group. As described above, according to the billing notification method according to the present invention, there is a means for accumulating call charges for extension telephone A or an extension telephone group, and a means for accumulating call charges for extension telephone A or extension telephone groups for comparing and confirming the level of call charges. By providing a means for registering any allowable call charges in advance, the following services can be provided.

First, when using the allowable call charges that can be registered arbitrarily for extension telephones by setting a call charge value of about 1 to 10,000 yen, when the subscriber makes a call at a certain period of time during a call to a paid area. The call charge is calculated from the start time, and when it matches the allowable call charge registered in advance for the extension telephone, the subscriber is made to hear a warning tone for a certain period of time, and from then on, the call charge is calculated for the same amount as the allowable call charge. By hearing a warning tone for a certain period of time each time the call charge increases, the subscriber can easily and accurately know the call charge. Second, when certifying a value equivalent to call charges accumulated over a long period of time as an allowable call charge, it is necessary for the subscriber to make a call to a pay area, . At the time of dialing,
During a call and at the end of a call, if the accumulated call charge corresponding to said subscriber exceeds the permissible call charge corresponding to said subscriber, said subscriber is conventionally given a warning, for example, by dialing a dial number. At times, there is a call restriction connection that gives a warning tone or warning announcement, an attendant transfer connection that connects to a telephone exchange operator, a warning call connection that allows you to hear a warning tone for a certain period of time before making a call, and a warning tone connection that gives a certain period of time when a call is in progress. Alternatively, by performing an announcement connection that automatically calls the subscriber and makes a warning announcement at the end of a call, the subscriber can easily know the extent of the call charge, and the call connection can be made depending on the call charge. can be easily regulated. Furthermore, at the end of the call, a message indicating that the allowable call charge has been exceeded can be displayed on a type of input/output device generally used in an automatic exchange machine, so that the exchange manager can give a warning to the subscriber. Thirdly, in both the first and second cases, allowable call charges can be arbitrarily registered for extension telephones, so flexible services can be provided according to the individuality of the subscriber. Furthermore, if the means for accumulating call charges and the means for registering arbitrary call charges in advance are made compatible with extension telephone groups, subscribers belonging to this extension telephone group can
Since you can receive the same services as in the case of , you can easily manage call charges for each extension telephone group. As explained above, the present invention registers an arbitrary allowable call charge in advance in order to compare and confirm the extent of call charges, and by hearing a warning tone for a certain period of time when the call charge increases by the same amount as the allowable call charge. , it is possible to easily and accurately inform subscribers of call charges.

In addition, the amount of call charges can be easily determined by making an announcement connection that automatically calls the subscriber and makes a warning announcement, making it easy to regulate outgoing connections based on the amount of call charges. An indication of an excess of the allowable call charge allows the switch administrator to give a warning to the subscriber. Furthermore, it has the advantage of being able to easily manage flexible services that match the individuality of subscribers, services for extension telephone groups, and call charges.
