As shown in FIG. 2 and FIG. 3, the gateway exchange 20 has an identification code + Prefix + area code + which is an incoming number to which an identification code of an automatic collect call from the originating subscriber terminal 12 has been added via the VLR 16.
Receive the station number + subscriber number from the incoming line (step A
1). The received call number is analyzed to determine whether or not the identification code is a collect call (step A2). If the result of the determination is that the call is not a collect call, the operation is terminated and normal call processing is performed. If the result of determination in step A2 is that the call is a collect call, an index of the control point 22 of the automatic collect call is set and this information is stored (step A3). Prefix and area code are deleted according to the identification code or condition added as an automatic collect call (step A4). It analyzes the station number + subscriber number of the received incoming number to determine whether it is a general public network number (step A5). If the result of the determination is that it is a general public network number, the general public network is captured and this relay connection becomes the connection control point for automatic collect calls.
A call number and an index indicating that the call is a collect call are transmitted on the signal according to a common channel signaling system or an individual signaling system for use in control of an automatic collect call rejection subscriber, and the called number is transmitted (step A6). The process proceeds to step A13. As a result of the determination, if the number is not a general public network number, the outgoing line of the dedicated line 24 is captured, and this relay connection becomes a connection control point of an automatic collect call.
The incoming call number and the setting of an indicator of a collect call on the signal are transmitted according to the common channel signaling system or the individual signaling system used for controlling the automatic collect call rejection subscriber (step A7). An incoming number is received from the incoming line of the dedicated line 24 (step A8), the location registration information of the incoming subscriber is inquired to the HLR 10 based on the received incoming number (step A9), and the VLR 18 is connected based on this information (step A10). ). The VLR 18 calls the called subscriber terminal 14, and if there is a response from the called subscriber terminal 14, sends a response signal to the gateway exchange 20, and the gateway exchange 20 receives it (step A11).
The response signal is relayed to the control point 22 via the dedicated line 24 (step A12).

When the control point 22 receives this response signal, it issues an announcement "Please wait" (ANT-W) to both the calling subscriber terminal 12 and the called subscriber terminal 14, and simultaneously announces the next connection. We are currently confirming that we will receive a collect call. ”(A
(NT-A) and the called subscriber, "This call is a cash-on-delivery." (ANT-B) (step A13). When the cueing of ANT-A and ANT-B is completed, an announcement having the content of ANT-A is connected to the calling subscriber terminal 12, and an announcement called ANT-B is sent to the called subscriber terminal 14. Connection is made (step A14). ANT-A and ANT-B are always synchronized and have the same message length, and determine whether a one-cycle announcement has been sent and time-out has occurred or a call disconnection request has been made (step A15). If the result of the determination is that there is a call disconnection request, the operation ends. Incoming subscriber terminal 1
4 disconnects the call during the announcement connection, which results in a call disconnection request (step A16). If the result of the determination is that an automatic collect call has been accepted, both announcements are released to make a call, and charging is started (step A17).
Ending subscriber terminal 12 or receiving subscriber terminal 1
In response to the disconnection signal received from No. 4, call release processing similar to the general call is performed, and charging is stopped (step A18).

As shown in FIG. 4, this operation is a service for automatically rejecting an automatic collect call at all times by applying for registration to a telephone company in advance and registering it in the restriction type of the subscriber data specified by the HLR. Then, the destination receiving station that has received the automatic collect call automatically rejects and disconnects. When the called party is a public network, the gateway station is used as a control point and is directly connected to a relay station of the public network without using a dedicated line.

Upon receiving a call from the gateway exchange 20, the VLR 18 on the receiving side determines whether or not the call is a collect call (step B1). If the result of the determination is that the call is a collect call, it is determined whether the called subscriber is a collect call rejection registrant (step B2). If the result of the determination is that the registrant is a rejection registrant, the call operation is forcibly cut off as an automatic collect call rejection (step B3), and the operation ends. If the result of determination in steps B1 and B2 is that the call is not a collect call, or if the call is a collect call and not a rejected registrant, normal incoming subscriber call processing is performed (step B4), and the operation is terminated.
