Recently, an answering machine having only a function of transmitting a caller ID transmitted from an exchange to a telephone subscriber at the time of incoming or out of use of a telephone has been widely used. Send and receive messages.

The operation of the caller information system is performed as follows.

During a call on-hook (while not on a call), if the caller passes the phone number to the caller-side exchange, the caller-side exchange is connected to the receiver-side exchange, which then sends the caller information to the receiver-side exchange. .

The receiver side exchange rings on the receiver side using the sender information protocol, delivers the sender's information to the receiver side phone, and the receiver side phone processes the outgoing information data and displays it on the display window.

At the time of off-call (calling state), if the caller forwards the phone number to the caller-side exchange, the caller-side exchange is connected to the receiver-side exchange, which then sends the caller information to the receiver-side exchange. .

The recipient side exchange informs the recipient on the call using the caller information protocol that the caller information data is delivered, delivers the caller information to the receiver side phone, and the recipient side exchange processes the caller information data and displays it on the display window. At this time, during the data transmission, the existing busy route temporarily suspends the call connection.

When the subscriber receives an incoming call, that is, when the calling terminal 230 requests a call to the called terminal 210 subscribing to the service (step S320), the calling switching center 240 (hereinafter referred to as mobile switching center; ) Requests location information of the called terminal 210 from the HLR 220 (LocationRequest Invoke). Then, it is checked whether the called terminal 210 is a terminal subscribed to the service based on the subscriber profile of the called terminal 210 based on the subscriber information from the HLR 220. As a result of the check, when the called terminal 210 is a terminal subscribed to the service, the HLR 220 originates including control information that can be connected to the incoming call interception equipment based on the incoming call interception service information. Performs a LocationRequest Return Result with the MSC, and the originating MSC causes the call to be connected to the interception equipment 250 using the call connection control information received from the HLR (steps S321, S322, S323, and S330). . At this time, the MSC 240 communicates with the HLR 220 using a common signal processing scheme of a standard signal processing protocol.

For example, when the HLR 220 inquires the location of the called terminal 210 in the calling MSC 240 and confirms that the called terminal 210 is a service subscription terminal, the HLR 220 calls the calling terminal. Providing a routing number of the interception equipment 250 to the MSC 240, so that the originating MSC 240 forms a call path with the interception equipment 250.

When the interception equipment 250 receives a call request from the originating MSC 240 to the called terminal 210, the interception equipment 250 forms a two-way communication path with the originating MSC 240, and sends the call to the called MSC 260. A call is made to the called terminal 210 to form a one-way communication path with the called terminal 210 (S340, S350, S360, and S370). That is, the call path of the calling terminal 230 and the called terminal 210 is formed (or set) through the intercepting equipment 250, and the calling terminal 230 and the intercepting equipment 250. The communication path between the two-way, the communication path between the intercepting equipment 250 and the called terminal 210 is a one-way call in which a voice signal is transmitted only from the intercepting equipment 250 to the called terminal 210. The furnace is formed.

Subsequently, when the call path is formed, the interception equipment 250 provides a predetermined announcement broadcast about the service to the calling terminal 240 (step S380).

When the user of the calling terminal 230 speaks a voice to be delivered according to the announcement broadcast from the intercepting equipment 250, the intercepting equipment 250 sounds from the calling terminal 230 (or A voice signal) is recorded corresponding to the called terminal 210 (S390).

Meanwhile, a user of the called terminal 210 may listen to the voice through the interception equipment 250. That is, the caller's voice may be heard through the path of the calling terminal 230 → the calling MSC 240 → the intercepting equipment 250 → the called MSC 260 → the called terminal 210.

If the user of the called terminal 210, i.e., the subscriber, needs a call immediately while listening to the voice, and selects a predetermined button (not shown: or a specific key) of the called terminal 210 for the call, the interception equipment In response to the button selection, 250 forms a two-way communication path between the called terminal 210 and the calling terminal 230 (S391, S392, S393).
