Upon the receipt of the transfer request, a charging information transfer means 11 requests a charging stop to a caller subscriber to a charging information storage section 12 and receives the charging information up to a charge stop point of time and sends it to the called exchange 20. Then the charging object subscriber is revised into the called subscriber with a simple operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call charging method for charging a communication charge to an incoming subscriber. In the public communication network, it is a principle that the calling subscriber bears the communication charge, but an incoming call charging service in which the receiving subscriber bears the communication charge is also widely used. A typical incoming call billing service for domestic calls is a service in which the receiving subscriber bears the charges for calls from an unspecified number of calling subscribers to a particular receiving subscriber. In addition to the limited number of subscribers, the area of the calling subscriber is often specified.

On the other hand, there is an incoming call paying call (collect call) as an incoming call billing service in which an unspecified called subscriber bears the call charge. However, in addition to the call charge, there is a handling charge. There are not a few users who avoid this service because it is added.

[0003] In addition to what is generally used as a simple method of burdening a called subscriber with a call charge without using a switch, the calling subscriber connects to the called subscriber and "calls back" to the called subscriber. There is a method in which the called subscriber makes a call back connection to the calling subscriber by requesting (hereinafter referred to as call back connection). However, this method has a disadvantage in that the called subscriber has to check the calling subscriber's number and dial the calling subscriber's telephone number, which is a troublesome task for the called subscriber.

Therefore, without making a call back connection,
There is a demand for an incoming charging method that does not require dialing of the telephone number of the calling subscriber even when the subscriber to be charged is changed from the calling subscriber to the called subscriber or a call back connection is made.

[0005]

2. Description of the Related Art FIG. 7 is a prior art connection configuration diagram, and FIG. 8 is a prior art call back connection sequence diagram. Hereinafter, the incoming call charging method by the call back connection in the prior art will be described with reference to FIG. 7 and FIG. It is to be noted that are symbols for identifying each operation of the sequence in FIG.

In FIG. 7, the calling subscriber 1 is the called subscriber 2
When a call is made to connect to the called subscriber 2 and the telephone number of the called subscriber 2 is dialed, the switching device 50 accommodating the calling subscriber 1 to the switching device 60 accommodating the called subscriber 2 (hereinafter, the subscriber who first makes the call). Caller is the calling subscriber, the other party of the first call is the called subscriber, the exchange accommodating the calling subscriber is referred to as the originating exchange, and the exchange accommodating the called subscriber is referred to as an incoming exchange). The called subscriber 2 is called (FIG. 8, hereinafter, FIG. 8 is omitted).

When the terminating subscriber 2 responds, a response indication signal is sent to the originating exchange 50 (), and the originating subscriber 1 and the terminating subscriber 2 receive the switching network (NW. 55) and exit trunk (OG
T) 57 and the incoming trunk (ICT) 68 of the exchange 60 and the path formed by the communication network (NW) 65 are available ().

When the calling subscriber 2 wants to bear the charge for this call, the calling subscriber 1 performs self-callback connection from the called subscriber 2 side to the called subscriber 2 so that the called subscriber 2 can make a call back connection. Notify your phone number and go on-hook (hang up). This disconnects the call path ().

After the called subscriber 2 goes on-hook,
Call again (off-hook) and dial the notified telephone number. The terminating exchange 60 connects to the calling subscriber 1 in the same manner as a normal call ().

When the calling subscriber 1 (which is a called party in the call back connection) responds, a response indication signal is sent to the terminating exchange 60 (), and the terminating subscriber 2 and the terminating subscriber 1 are terminating exchanges.
A call is made through a path formed by a call path network 65 of 60 and an outgoing trunk (OGT) 67, an incoming trunk (ICT) 58 of the originating exchange 50 and a call path network 55 ().

In this call back connection from the called subscriber 2, the called subscriber 2 becomes the calling party. Therefore, the calling charge after the calling subscriber 1 responds to the called subscriber 2 according to the billing principle of the exchange. You will be charged. Therefore, the calling subscriber 1 is only charged with the short-term call charge when the calling subscriber 2 requests the call back connection for the first call ().

However, in this call back connection, the called subscriber 2 prepares a memo and the like, listens to the telephone number of the calling subscriber 1 from the calling subscriber 1, and repeats it if necessary, and confirms it. You need to make a call using that telephone number. For this reason, the call time charged to the calling subscriber 1 may increase due to an increase in the initial call time, and an error in dialing or the like is likely to occur, and the burden on the called subscriber 2 is prevented from increasing. Absent.

[0013]

As described above, in the prior art, if the called subscriber tries to make a call back connection in order to charge the called subscriber,
It takes time to confirm the telephone number of the calling subscriber between the calling subscriber and the called subscriber, and the call charge that the calling subscriber bears increases, and it is necessary to dial the telephone number of the calling subscriber. However, there was a drawback that it burdened the incoming subscriber.

An object of the present invention is to provide an incoming call charging method for changing a charging target subscriber to a called subscriber by a simple operation after starting communication.

Hereinafter, although FIG. 3 will be described in combination with FIG. 5, symbols (1) to (5) are symbols for identifying respective operations in the sequence of FIG.

Information such as connection control information is transmitted and received between the control device 14 of the originating exchange 10 and the control device 24 of the terminating exchange 20 in FIG. 3 via the common line signaling devices 13 and 23 and the common signal line 3.

In FIG. 3, when the calling subscriber 1 makes a call to the called subscriber 2 and dials, the control unit 14 of the calling exchange 10 selects a call line 4 from a plurality of call lines to the call receiving exchange 20. Is selected and the connection control information is sent from the common line signaling device 13 to the terminating exchange 20 via the common signal line 3. Upon receipt of this connection control information from the common line signaling device 23, the control device 24 of the terminating exchange 20 performs a connection process by a known method and calls the terminating subscriber 2 (in FIG. 5).

When the terminating subscriber 2 responds, a response display is sent from the terminating exchange 20 to the originating exchange 10 via the common signal line 3 (in FIG. 5). In some cases, the response indication to the originating subscriber 1 from the originating exchange 10 may not be sent as a signal. However, regardless of the situation, the originating subscriber 1 and the terminating subscriber 2 have the subscriber circuit 16, the communication network 15, and the bidirectional trunk. The call is started on the path passing through 17, the communication line 4, the bidirectional trunk 27, the communication network 25, and the subscriber circuit 26 (see FIG. 5).

In this call, if it is agreed that the calling subscriber 2 bears the call charge between the calling subscriber 1 and the called subscriber 2, the called subscriber 2 joins the charging target according to a predetermined procedure. Request change of personnel. This charge target subscriber change request is made, for example, by hooking and dialing a special number predetermined for charge change request (FIG. 5).

Charged subscriber change request detection unit of the incoming exchange 20
When 21a detects this request, it extracts the information about the called subscriber 1 of the called subscriber 2 from the call monitoring information (details not shown) stored in the control device 24, and sends it to the billing information request unit 21b. send. When the billing information requesting unit 21b receives this information, it requests the originating exchange 10 via the common line signaling device 23 to transfer the billing information of the calling subscriber 1 (FIG. 5).
of). The charging subscriber change request detecting unit 21a and the charging information requesting unit 21b are an implementation of the charging subscriber change request processing means 21 in FIG.

The above request is received by the common line signaling device 13 of the originating exchange 10 via the common signal line 3, and then the control device 14 is operated.
It is sent to the charging information transfer processing unit 11 therein. Although the call is billed for the call of the calling subscriber 1 in the control device 14 and the billing information is stored in the billing information storage unit 12, the billing information transfer processing unit 11 bills when the above request is received. Information storage
It requests the subscriber 12 to stop charging the calling subscriber 1 for the call, and also requests the transfer of the charging information of the calling subscriber 1 up to the point when the charging is stopped. This billing information is the call charge information or the information necessary to calculate the call charge,
For example, the other party subscriber number, call start time information, billing stop time information, and the like.

When the billing information storage unit 12 stops billing and then sends the above billing information to the billing information transfer processing unit 11 (in FIG. 5), the billing information transfer processing unit 11 sends this billing information to the common line signaling device 13 The data is transferred to the incoming call exchange 20 via the Internet (in FIG. 5). In the terminating exchange 20, the above billing information is common line signaling device.
After being received by the charging information receiving unit 22a via 23, it is sent to the charging change processing unit 22b. The billing information receiver 22a
The charge change processing unit 22b is an implementation of the charge processing unit 22 in FIG.

The billing change processing unit 22b carries out a process of billing the called subscriber 2 with the call charge indicated by the billing information of the calling subscriber 1 sent from the originating exchange 10 and, for example, the calling exchange 10 makes a call. The billing is started by setting the time when the billing for the subscriber 1 is stopped to the call start time of the receiving subscriber 2. After that, the call of the called subscriber 2 is monitored, and the called subscriber 2 disconnects the call (on-hook).
The charging of the called subscriber 2 is continued until
).

As described above, all the call charges from the start of the call are charged to the called subscriber 2, but during that time, the called subscriber 2 only has to perform a simple operation to request the change of the charged subscriber. Well, the call between the calling subscriber 1 and the called subscriber 2 is hardly interrupted. Further, the fact that the request for changing the charging subscriber is made by the receiving subscriber 2 indicates that the receiving subscriber 2 has approved the incoming charging, so that no trouble will occur around the charge bearer.

Next, FIG. 4 will be described. 4 is shown in FIG.
FIG. 6 is a diagram showing an example of a connection configuration based on the principle explanatory diagram of FIG. 6, and FIG. 6 is a diagram showing an example of a sequence in the connection configuration of FIG. Hereinafter, FIG. 3 will be described in combination with FIG.
Is a code for identifying each operation of the sequence of FIG.

In FIG. 4, when the originating subscriber 1 makes a call to connect to the terminating subscriber 2 and dials the telephone number of the terminating subscriber 2, the control device 34 of the originating exchange 30 makes the call line to the terminating exchange 40. Outgoing trunk 37 is selected from a plurality of outgoing trunks connected to, and connection is made via telephone line 5. The call connected to the incoming trunk 48 is subjected to normal connection processing by the control device 44 of the incoming exchange 40 to call the called subscriber 2 (see FIG. 6).

At this time, the sender ID information (hereinafter referred to as ID information) of the calling subscriber 1 is sent from the ID sending unit 31 (implementation mode of the calling party identification information sending means 31 in FIG. 1) 31 of the calling exchange 30 to the calling line. 5 is sent to the terminating exchange 40, and in the terminating exchange 40, the ID storage unit (implementation form of the sender identification information storage means of FIG. 1) 41 receives and stores this ID information.

When the terminating subscriber 2 responds, a response display signal is sent to the originating exchange 30 (FIG. 6), and the originating subscriber 1 and the terminating subscriber 2 receive the subscriber circuit 36 of the originating exchange 30 and the communication network.
A call is made possible by the path formed by 35, the outgoing trunk 37, the call line 5, and the incoming trunk 48 of the incoming exchange 40, the call network 45, and the subscriber circuit 46 (see FIG. 6).

Here, when it is necessary to charge the called subscriber 2 with the call charge of the original requirement, the calling subscriber 1 requests the called subscriber 2 to make a call back connection. When the called subscriber 2 accepts this request, he / she performs a call back connection operation. This operation is carried out, for example, by hooking and then dialing a predetermined special number for call back connection request (Fig. 6).

In the incoming call exchange 40, a register (not shown) is connected by hooking to the subscriber circuit 46 of the terminating subscriber 2 via the call path network 45 to receive the special number for the call back request. By receiving this special number, the controller 44
The call back request detection unit 42a therein is activated to detect a call back connection request. When the call back request detection unit 42a detects the call back connection request, the call back request detection unit 42a identifies the receiving subscriber 2 (for example,
A telephone number or accommodation location information) is attached to the call back connection execution unit 42b to instruct execution of the call back connection. The call back request detection unit 42a and the call back connection execution unit 42b
Is an implementation of the call back connection means 42 of FIG.

Upon receipt of this instruction, the call back connection execution unit 42b disconnects the connection of the communication network 45 between the incoming trunk 48 to which the calling subscriber 1 is connected and the subscriber circuit 46 of the called subscriber 2, The talkie transmitter 49 is connected to the incoming trunk 48. The talkie sending unit 49 sends to the calling subscriber 1 a talkie announcement urging that "call back (put on-hook) to call back" (Fig. 6).

When the calling subscriber 1 who listens to the talkie announcement goes on hook, the call line 5 is disconnected (see FIG. 6).
), The call back connection executing unit 42b confirms that the calling subscriber 1 is on-hook because the incoming trunk 48 is released. When this confirmation is performed, the call back connection execution unit 42b determines that the ID storage unit 41
To retrieve the ID information of the calling subscriber at the other end by using the identification information of the called subscriber 2 sent from the call back request detector 42a.

When it is confirmed by this search that the calling subscriber is the calling subscriber 1, the call back connection executing unit 42b
Captures the empty trunk 47 as in the normal connection process,
ID information (usually a telephone number) of the calling subscriber 1 is sent from the outgoing trunk 47. The control device 34 of the originating exchange 30 receives the connection information from the incoming trunk 38 and connects to the originating subscriber 1 (in FIG. 6).

When the calling subscriber 1 answers the call (in FIG. 6), the called subscriber 2 and the calling subscriber 1 receive the call.
40 subscriber circuits 46, telephone network 45, outgoing trunk 47, telephone line 6, incoming trunk 38 of originating exchange 30, telephone network 3
5. The call through the path through the subscriber circuit 36 becomes possible (in FIG. 6). The call after this call back is made by the receiving subscriber 2
Is the calling party, the billing processing unit 43 monitors the call and bills with the called subscriber 2 as the calling party, as in a normal call.

As is apparent from the sequence of FIG. 6, the first call (in FIG. 6) originated by the calling subscriber 1 is a short-time call for which a call back request is made.
The call after the call back () is a call of the original requirement and thus may take a long time. However, since the call charge is charged to the called subscriber 2 as described above, the calling subscriber 1 Only needs to pay the initial short-term call charges and can fulfill the purpose of incoming call billing.

Further, although the call charge bearer is changed by the call back connection, the called subscriber 2
Does not need to confirm the telephone number of the calling subscriber 1, and only needs to dial a special number (generally a short digit number) defined for hooking and call back connection request. There is no possibility that the call charge for the calling subscriber 1 becomes heavy because the initial call is lengthened to confirm the number. Further, since the called subscriber 2 does not need to confirm or dial the telephone number of the calling subscriber 1 at the time of calling back, the operational burden is small and erroneous dialing does not occur.

In addition, in the configuration of FIG.
The ID sending unit 31 is required for the D sending unit 31 and the incoming exchange 40, but with the spread of ISDN, I
Since it is expected that the transfer of D information will be a general function, there is little possibility that these facilities will be an economical burden as dedicated facilities for carrying out the present invention. In other words, it can be said that the incoming call charging method according to the configuration of FIG. 4 is suitable for a communication network in which the transfer of ID information is general.

Although the embodiment of the present invention has been described above with reference to FIGS. 3 to 6, FIGS. 3 to 6 merely show a part of the embodiment of the present invention. Figure 6
It goes without saying that the contents are not limited to those shown in FIG. For example, although the outgoing exchanges 10 and 30 and the incoming exchanges 20 and 40 are separate from each other in the above description, it is natural that the exchange accommodating the subscriber serves as both the outgoing exchange and the incoming exchange. It goes without saying that the constituent parts shown in the respective exchanges are provided in both the originating exchange and the terminating exchange.

Although the common signal line 3 is provided between the originating exchange 10 and the terminating exchange 20 in FIG. 3, the common signal line 3 does not transfer information only between the two exchanges. The effect of the present invention does not change even if the signal line relays another exchange, which is well known and not shown.

Further, in FIG. 4, outgoing trunk 37 and incoming trunk 38 to outgoing exchange 30 and outgoing trunk to incoming exchange 40 are shown.
Although 47 and incoming trunk 48 are provided, the effect of the present invention can be obtained even if a bidirectional trunk (BWT) is used instead of these incoming and outgoing trunks or a common signal line is set between the originating exchange 30 and the incoming exchange 40. does not change.

Although the charging information storage unit 12 in FIG. 3 and the ID storage unit 41 in FIG. 4 are provided in the control device 14 or the control device 44, these are not shown in the storage device. Even if provided, the effect of the present invention does not change.

[0056]

As described above, according to the present invention,
After the call is started, the called subscriber requests from the calling subscriber to change the charging subscriber or request a call back connection to change the subscriber who is charged for the communication charge from the calling subscriber to the called subscriber. . In particular, if a common signal line is provided between the exchanges accommodating the calling and called subscribers, all the communication charges are charged to the called subscriber by transferring the billing information through the common signal line during communication. Therefore, the calling subscriber does not have to pay the communication fee at all,
Moreover, it has an excellent effect that the call is not interrupted for changing to the incoming call billing.

Further, in the incoming call charging method by the call back connection, the communication charge before the call back connection is charged to the calling subscriber, but since the called subscriber does not need to confirm the telephone number of the calling subscriber, There is no need to increase the call charges for the calling subscriber due to the confirmation time, and the burden on the called subscriber can be reduced because there is no need to confirm or dial the telephone number when calling back. It has the effect of not delaying call back due to incorrect dialing.

As described above, the present invention expands the usage form of the incoming call billing service and greatly contributes to the improvement of the convenience of the communication service.
