DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital mobile telephone switching system, and more particularly, to a call destination and a call source when making and receiving a call, and in accordance with the limited range of the call destination and the call source area. The present invention relates to a digital car telephone switching system that calculates a charge according to a charge system having a charge difference and performs a charge process.

[0002]

2. Description of the Related Art In the charging system of a conventional digital car telephone switching system, the amount to be collected is determined by the distance to the called party and the talking time, regardless of whether the calling party or the called party is charged. Calls are made at different rates depending on the time of day of the call and the day of the call on Sundays and holidays. However, there is a disparity in the price per unit time between a subscriber who makes and receives calls many times in a specific area, but does not make and receive calls outside the area, and a subscriber who makes and receives calls in all areas. It was not provided.

[0003]

In the conventional digital car telephone switching system described above, calls are made and received many times within a specific area, but no calls are made to and from a destination outside the area. Therefore, a subscriber who does not use a transit exchange and a transit line necessary for a call with a destination outside the area is a subscriber who uses a transit exchange and a transit line for a call with a destination outside the area. However, it has the disadvantage that the price per unit time cannot be reduced.

[0004] An object of the present invention is to provide a difference in the charge per unit time between a subscriber who only makes a call within a specific area and a subscriber who makes a call with a partner outside that area. It is to provide a digital car telephone switching system.

[0005]

Next, the operation will be described.

In FIG. 1, a calling signal 11 from the subscriber 1 is input to the subscriber data management unit 5 of the exchange 3 by the calling of the subscriber 1. The subscriber data management unit 5 which has input the calling signal including the charging area of the subscriber 1 as information is based on the charging area information extracted from the calling signal 11 and stores the stored subscriber calling range division. From the information, the subscriber calling range classification information 12 for the subscriber 1 is issued.
It is output to the necessity determining unit 6. Judgment of caller restriction
The unit 6 determines whether or not to restrict the call from the subscriber 1 to the subscriber 2 based on the subscriber calling range classification information output from the subscriber data management unit 5. As a result of the determination, the call from the subscriber 1 indicates that the range of the callable area predetermined in the subscriber calling range classification information 12 reflecting the agreement items of the subscriber 1 at the time of subscription is reflected. If the call from the subscriber 1 cannot be connected to the called subscriber 2 as a call to be regulated because the call is out, the subscriber 1
A guidance device connection request signal 13 is output to the call processing unit 8 to request the call processing unit 8 to connect the call from the guidance device 4 to the guidance device 4. If the result of the determination is that connection to the subscriber 2 on the receiving side is permitted, the call information 1 for the subscriber 1
4 is output to the call processing unit 8. The call processing unit 8 that has received the guidance device connection request signal 13 performs a process of connecting a call from the subscriber 1 to the guidance device 4. When a call from the subscriber 1 is connected to the guidance device 4, the connection from the guidance device 4 to the destination subscriber 2 is automatically recorded beforehand from the guidance device 4 to the subscriber 1. The message to the effect that it is impossible is conveyed by voice. Caller
When the result of determination by the restriction necessity determination unit 6 is that connection to the subscriber 2 of the other party is permitted, the call for the subscriber 2 required to connect the call from the subscriber 1 to the subscriber 2 is determined. In order for the call processing unit 8 to receive the information from the subscriber data management unit 7, the outgoing call information 14 from the subscriber 1 output from the calling side restriction necessity determination unit 6 to the call processing unit 8 further includes a call processing unit 8 to the subscriber data management unit 7 as call information 14. The subscriber data management unit 7 receives a subscriber call for the subscriber 2 indicated by the call information 15 from the subscriber 1 from the subscriber call range information of the managed subscriber. The range division information 16 is extracted and output to the call processing unit 8.
The call processing unit 8 receives the subscriber incoming call range division information 16 of the subscriber 2 output from the subscriber data management unit 7 and outputs it as the subscriber incoming call range division information 17 to the receiving side restriction necessity determination unit 9. I do. The receiving side restriction necessity determining unit 9 receives the subscriber incoming call range division information 17 of the subscriber 2 output from the call processing unit 8, and determines whether or not the subscriber 2 is subject to incoming call restriction. The result of the determination indicates that the call from the subscriber 1 is a callable source which can be called in advance in the subscriber's calling range classification information 17 reflecting the agreement items at the time of the subscription contract of the subscriber 2. Therefore, when a request for regulation is made, the call processing unit 8 instructs the call processing unit 8 to connect the call from the subscriber 1 to the guidance device 4.
Output and request. The call processing unit 8 that has received the guidance device connection request signal 18 performs a process of connecting a call from the subscriber 1 to the guidance device 4. Further, when the determination result is acknowledges the connection between the subscriber 1, the terminating Tadashi
The control necessity judging unit 9 sends a connection request signal 21 to the subscriber 2 to connect the call from the subscriber 1 to the subscriber 2, and requests a connection. The response signal 22 is returned from the subscriber 2 receiving the connection request signal 21 to the call processing unit 8, and the connection is completed. The call processing unit 8 outputs a charge calculation request signal 19 to the charge calculation unit 10 when the connection between the subscriber 1 and the subscriber 2 is completed and the call ends and the subscriber disconnects the line. The charge calculation unit 10 receives the charge calculation request signal 1 output from the call processing unit 8.
9 and outputs the calculated charge to the call processing unit 8. In calculating the charge, the charge is calculated according to a charging system in which the charge difference is set according to the subscriber calling range classification, and is output to the call processing unit 8 as the charge information 20.

[0014]

As described above, the digital mobile telephone switching system according to the present invention has a step-by-step billing area of a call destination to which a subscriber can make a call, and the subscriber can receive a call. The range of the charging area of the calling source divided stepwise is set in advance for each subscriber, and when a call is made, whether or not the call corresponds to the above-described range of the charging area for the call is determined. Is determined, and according to the determination result,
If the connection is not possible, connect the call to the guidance device that notifies the calling subscriber of the reason for the connection failure as a message.If the connection is possible, connect the call to the call destination. By calculating the charge according to the charge system in which the charge difference is set according to the setting area of the charge area, the subscriber who makes a call only in a specific area and a call that makes a call with a partner outside the area Differences in the price per unit time with the customer, diversifying the services paid by customers from the mobile telephone exchange,
This has the effect that the serviceability of the mobile telephone exchange can be improved.
