Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is connected to a network such as an ISDN network in which a subscriber's subscriber number is notified when a call arrives and a plurality of channels can be simultaneously used. It concerns telephones.

[Conventional technology]

Catalog sales, in which customers receive explanations of products and purchase applications over the telephone, rather than customers going directly to retailers to receive product explanations and purchases, are becoming popular.

Usually, when a customer calls a store, the call charge is charged to the customer side, but in order to improve the sales effect of the catalog,
There is a demand for a service in which the call charge is charged to the store side (the called side).

Currently, the service for charging the called party is realized as a service on the network side. In this service, the called party dials a special subscriber number for charging the called party, whereby the called party is charged at the same time as the start of communication. To use this service, a special subscriber number for charging the called party is used instead of the subscriber number normally used. For this reason, the caller must dial the special subscriber number for the called party billing, rather than the normal subscriber number. In addition, the called party takes time and effort to apply to the telephone station to use the service.

[Problems to be solved by the invention]

In fact, instead of requesting to be charged for incoming calls only at certain times of the day, or only when receiving calls from a specific party, or not to charge the called party 100%,
For example, there is a demand for the caller and the callee to pay 50% each. In response to such a request, it is conceivable to realize a function in the terminal so as to flexibly respond to the user operation. However, existing telephone terminals do not have the function of satisfying the above demands.

In order to meet the above requirements using a telephone connected to the currently widely used analog telephone network, the subscriber who has answered the incoming call, confirmed the subscriber number of the other party, terminated the communication, and confirmed the subscriber. The user needs to perform a series of operations for making a call to the number.

In this case, once the incoming call is answered, the calling party is charged at that time, so it is impossible to set the calling charge to zero. Further, since it is necessary to end the call once when making a call again, the call is interrupted while the called user is making a call operation. Furthermore, the user on the receiving side needs to input the telephone number confirmed by using a dial key or the like, so that there is a problem that the time required for the calling operation is not short.

[Means for Solving the Problems] The invention according to claim (1) of the telephone set according to the present invention is a notification number memory and a transmission circuit for receiving and storing the subscriber number of the caller notified from the network when an incoming call arrives. And the subscriber number of the calling party notified from the network at the time of incoming call is stored in the notification number memory, and the number is stored in the notification number memory using an unused channel by the transmission circuit. It is provided with a control unit for automatically transmitting.

Further, the invention according to claim (2) includes a registration number memory in which a user registers a subscriber number in advance, and a subscriber number comparison circuit for comparing the stored contents of the notification number memory and the registration number memory. The subscriber number comparison circuit compares the contents of the notification number memory and the contents of the registration number memory when an incoming call is received, and has a control unit that determines whether or not to perform the automatic transmission operation according to the comparison result. is there.

Further, the invention according to claim (3) has a calling key for instructing a calling operation, and when the calling key is pressed during a call, the subscriber number stored in the notification number memory , And a control unit for making a call using an unused channel.

The invention according to claim (4) has a calling number memory for storing the subscriber number when making a call to the subscriber number input by the user operation, and is activated by the calling operation. When an incoming call arrives before the placed call becomes the call state, the contents of the notification number memory and the contents of the calling number memory are compared by the subscriber number comparison circuit, and if they match, the incoming call is automatically received. It is provided with a control unit that responds and starts communication using the responded channel, and automatically releases the channel that has been communicating until then.

[Action]

In the invention described in claim (1) of the present invention, when an incoming call is received, an automatic call is made using a vacant channel in which the incoming call has not arrived for the subscriber number stored in the notification number memory. This eliminates the need to start a call, disconnect the call after confirming the other party's subscriber number, and the operation of inputting the other party's subscriber number.

Further, in the invention described in claim (2), the subscriber number notified at the time of an incoming call is compared with the contents of the registration number memory, and it is determined whether or not the re-calling operation is performed according to the result.

Further, in the invention described in claim (3), a special transmission key is provided and the key is pressed for the purpose of sharing the call charge by both sides, not by the transmission side or the reception side. Only when this time, the transmission operation is performed using the above vacant channel.

Further, in the invention described in claim (4), when an incoming call arrives in the presence of a call activated by an outgoing call operation, the outgoing subscriber number is compared with the subscriber number notified at the same time as the incoming call. If the comparison results are in agreement, it is judged that the other party who is making a call or is on a call has redialed, responds to the incoming call, and releases the call that has been used for making or making a call.

〔Example〕

FIG. 1 shows a block configuration of an embodiment (an invention according to claim (1)) of the present invention. A network interface unit 1 is physically or logically connected to a network having a plurality of channels, controls an interface with a transmitting / receiving means or a transmitting means, which will be described later, and confirms whether or not there is a vacant channel in the network. 2 is a subscriber number information receiving circuit for detecting an incoming signal notified from the network and receiving the notified subscriber number information of the other party. 3 is a subscriber number received by the subscriber number information receiving circuit 2. A notification number memory for recording information, 7 is a calling key such as a button to be pressed when the user makes a call again during a call, and 8 is a network interface for a destination subscriber number input by the user using a dial. A sending circuit for sending a call through the unit 1, a control unit 9 for controlling various memories and circuits, a ringing tone ringing circuit for ringing a ringing tone when an incoming call arrives, and a user calling 11 Dial buttons for registering a subscriber number in the number memory 5 or for dialing 0-9, *, # when making a call, and 12 are transmitting and receiving means for a user to talk.

 Next, the operation of this embodiment will be described with reference to FIG.

FIG. 2 is a flow chart explaining the operation of the embodiment when an incoming call arrives in the standby state. Note that (1) to (9) indicate each step.

When an incoming call arrives (1), the subscriber number information receiving circuit 2 receives the subscriber number information sent from the telephone network and records it in the notification number memory 3, and (2) the ringing tone ringing circuit 10 receives it. It starts (3). When the subscriber number of the called party is recorded in the notification number memory 3, the transmitting circuit 8 uses a channel vacant for the subscriber number stored in the notification number memory 3 according to an instruction from the control unit 9. Make a call (4). For example, when the incoming call specifies the B1 channel, the outgoing call is made using the B2 channel. When it is confirmed that the other party is busy for the outgoing call, the outgoing call operation is repeated again (5).

On the other hand, the other party who originally made the call responds to the incoming call during the call. When the response from the other party is confirmed, the transmission / reception means 12 is connected to the channel where the response from the other party has arrived (6), and the ringing tone ringing circuit 10 is stopped (7). As a result, a call using the transmitting / receiving means 12 is started (8). At this time, since the call has been activated by the call originating from the side that initially received the call, the side that originally called the call, that is, the caller in this embodiment is charged. The call is continued until it is confirmed that the other party is abandoned or the user in this embodiment abandons the call (specifically, the operation of putting the transmitting / receiving means 12 back to the original state) (9), and then the operation ends.

FIG. 3 shows another embodiment of the present invention (claim (2),
It is a block diagram showing the invention described in (3). In this figure, 4 is a registration number memory in which the user registers a specific subscriber number in advance, 6 is the notification number memory 3, registration number memory
4, a subscriber number comparison circuit for comparing the contents stored in the transmission number memory 5 and comparing whether or not they match, the other parts being the same as in FIG.

Next, the operation of the embodiment of FIG. 3 will be described with reference to the flowchart of FIG. In addition, (11) to (29) in FIG. 4 indicate each step.

When an incoming call arrives (11), the subscriber number information receiving circuit 2 receives the subscriber number information sent from the telephone network and stores it in the notification number memory 3 (12), and the ring tone ringing circuit 10 is activated. (13). When the subscriber number of the called party is stored in the notification number memory 3, the subscriber number comparison circuit 6 compares it with the subscriber number previously registered by the user in the registration number memory 4 (14). For example, when the user registers 1234567 in the registration number memory 4 by pressing the dial button 11, if the caller who has the subscriber number 12345467 receives an incoming call, the comparison result is a match, but the other subscriber numbers ( For example, the comparison result becomes inconsistent when a call is received from the other party who has 9876543). If the comparison results match, the control unit 9
In response to this instruction, the transmission circuit 8 transmits using the vacant channel for the subscriber number stored in the notification number memory 3 (15). For example, when the incoming call specifies the B1 channel, the B2 channel is used to make the outgoing call. When it is confirmed that the other party is busy for the outgoing call, the outgoing call operation is repeated again (16).

On the other hand, the person who originally made the call responds to the incoming call during the call. When the response of the other party is confirmed, the transmitting / receiving means 12 is connected to the channel where the other party's response has arrived (17), and the ringing circuit 10 is stopped (18). As a result, a call using the transmitting / receiving means 12 is started (19).
At this time, since the call has been activated by the call originating from the side that initially received the call, the side that originally called the call, that is, the caller in this embodiment is charged. The call is continued until it is confirmed that the other party is abandoned or the user of this embodiment abandons the call (specifically, the operation of putting the transmitting / receiving means 12 back to the original state) (2
0), then the operation ends.

The above-mentioned embodiment is an example of the transmission operation when the recorded contents of the notification number memory 3 and the registered contents of the registration number memory 4 are the same. An example of making a call to the called party when the registered contents of the memory 4 do not match can be considered.

If the result of comparison between the subscriber number recorded in the notification number memory 3 at the arrival of the incoming call and the subscriber number registered in advance in the registration number memory 4 by the user does not match (14), the user transmits and receives means. The ringing tone ringing circuit 10 continues ringing the ringing tone until the call is started by 12 or the calling side abandons the call (21), (22). After the call is started by the user via the transmitting / receiving means 12 (23) and the call key 7 is pressed by the user's operation (24), the incoming call recorded in the notification number memory 3 at the time of the incoming call A call is made using a free channel to the other party's subscriber number (25). At this time, if it is confirmed that the other party is busy for the outgoing call, the outgoing call is repeated again (26).

On the other hand, the person who is making the call first is responding to the incoming call during the call (27). When this other party's response is confirmed, the transmission / reception means 12 is connected to the channel for which the other party's response has been confirmed, and at the same time, the channel used for the call till then is opened (28). In this way, since the call after switching the call channel is started by the side that initially received the call (the side of this embodiment), the call fee is charged to the side of this embodiment. Also in this case, it is confirmed that the call is abandoned, or the user of this embodiment abandons the call (specifically, the operation of putting the transmitting / receiving means 12 back to the original state).
It continues until it does (20), and then the operation ends. If the party is abandoned in step (21), the ringing tone ends (2
9), the end.

FIG. 5 shows still another embodiment of the present invention (claim (4)).
5 is a calling number memory for recording a called subscriber number when a user makes a call using a dial, and is otherwise similar to FIG.

FIG. 6 is a flow chart for explaining the operation of this embodiment when a telephone call is initiated by a user call operation, and (31) to (44) show respective steps.

When the user presses the dial button 11 to input the subscriber number of the calling party (31), the calling circuit 8 calls the subscriber number via the network interface section 1 (32) and calls the calling number memory 5. The recorded subscriber number is recorded (33), and further, the transmitting / receiving means 12 is connected to the transmitting channel (34). After this (35), if there is a response from the caller, the call is started (36). When an incoming call arrives during a call or while a call is being made before the other party's response arrives (37), the subscriber number information receiving circuit 2 receives the subscriber information of the called party sent from the network and stores the call number memory. Three
Record in (38). Then, the subscriber number comparison circuit 6 compares the subscriber number recorded in the calling number memory 5 with the subscriber number recorded in the notification number memory 3 (3
9). If the comparison results are in agreement, it is determined that the other party who is making or calling is redialing for the purpose of paying the call charge, and the network interface unit 1 responds to the incoming call (40) and sends it. The receiving means 12 is connected to the newly arrived channel (41), and at the same time, the channel to which the transmitting / receiving means 12 was connected before the arrival of the incoming call is disconnected and opened (42). To make a call. Since the call at this time is activated by the other party, the call is also charged to the other party. The call continues until it is confirmed that the other party is abandoned or the user of this embodiment abandons the call (specifically, the operation of putting the transmitting / receiving means 12 back to the original position), and then the operation ends (43). Note that step (3
When the contents of the notification number memory 3 and the calling number memory 5 do not match in 9), the ring tone is sent from the ring tone ringing circuit 10 to notify the user of the arrival of the incoming call (44).
