Abstract

PROBLEM TO BE SOLVED: To realize receiver charge and enlarge variation of service, by discrimi nating the transmitter, without holding a lot of station data in an exchanger on the receiver side or using a specific service telephone number. SOLUTION: An LS 402 receives address signal from LS 401 and determines, whether it is a self-station related call, and then determines whether the receive subscriber is also a receiver charge service contract subscriber, when it is the self-station related call. When he is the service contract subscriber, the LS 402 is connected to an SCP 501 in the IN network and transmits an IDP signal and the LS 402 asks whether the transmitting subscriber's number that is received at the call arrival belongs to the service application subscriber, and receives the result. After the connection to the subscriber 300, a parameter for indicating the receiver charge call is set on the response signal to be transmitted to the LS 401, when the response signal received from the subscriber's terminal is the receiver charge call.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging system, and more particularly, to a called party charging system and a called party charging method for charging a call charge to a called party and a control program therefor.

[0002]

2. Description of the Related Art In recent years, telephone services have been diversified, and differentiation from existing services is required. Among them, free call, which is one of the typical telephone services, in which the callee bears the call charge, is increasing as the number of service contractors is increasing, and not only "0120" but also "0800" as a telephone number to identify this service. It is becoming used.
However, in this conventional called party charging method, the called party is charged regardless of who the calling party is. On the other hand, for example, Japanese Patent Laid-Open No. 4-51650 discloses a method of charging the called party when the called party is identified by the exchange on the called side and registered in advance.

[0003]

In the former of the above-mentioned conventional called party charging methods, the former must dial a predetermined telephone number for identifying called party charging from the viewpoint of the caller.
The subscriber must have this phone number, and
From the perspective of the called party, it is not possible to limit the calling party to which the service is applied. Further, in the latter method, it is necessary to hold the identification information of the called party and the identification information of the calling party in the exchange on the receiving side, and to select the charging destination also in this exchange. Usually, if the caller information is overwhelmingly overwhelmed by the amount of data related to this and this charging system is realized only by the exchange on the receiving side, a large amount of data is held, which is not desirable. Furthermore, a combination of services with existing intelligent networks (hereinafter referred to as IN networks) is required.

It is an object of the present invention to identify the caller and realize the callee billing without holding a large amount of station data in the exchange on the receiving side and without using a specific service telephone number, and a variation of the service. It is an object of the present invention to provide a called party charging method and a called party charging method, and a control program therefor.

[0005]

According to the callee charging system of the present invention, a calling subscriber terminal used as a calling means by a calling subscriber, a calling subscriber exchange accommodating the calling subscriber terminal, and Applicable when a billing device is connected to the subscriber exchange of the calling side and performs billing processing when the calling subscriber terminal makes a call, and when the called subscriber uses the billing service as a call means and a called party billing service is contracted. An incoming call-subscribing terminal that registers the target outgoing call-subscribing terminal in advance by an operation input via a communication network;
A gateway for outputting subscriber service information based on an instruction signal received from the called subscriber terminal via a communication network, and registration or update control for a database for a called party charging service based on the output information of the gateway. In addition, the database is searched based on the called subscriber number and the calling subscriber number, and it is determined whether or not the called call is a call to which the called party charging service is applied. When the service control point to be output and the called subscriber number are received, it is judged whether this number is a subscriber who subscribes to the called party billing service, and if it is determined that the subscriber is a subscriber, this called subscriber number The calling subscriber number received at the time of this incoming call is sent to the service control point, and the charging destination information is forwarded based on the inquiry result. And a terminating side local exchange to be sent to the originating local exchange.

According to the called party charging system of the present invention, a calling subscriber terminal used as a calling means by a calling subscriber, a calling subscriber exchange accommodating the calling subscriber terminal, and the calling subscriber exchange. A billing device that is connected and performs billing processing when the calling subscriber terminal makes a call, and a calling subscriber terminal that is applied when the called subscriber uses it as a communication means and a called party billing service is contracted Is registered in advance by an operation input via a communication network, a gateway for outputting subscriber service information based on an instruction signal received from the called subscriber via the communication network, and output information of the gateway. Based on this, registration or update control is performed on the database for the called party billing service, and the database is searched based on the called subscriber number and the calling subscriber number. When it is judged whether the call is a call to which the called party billing service is applied and the result is combined with the supplementary service, the service control point that outputs the relevant instruction signal and the called subscriber number are received and this number is received. It is determined whether or not the subscriber is a subscriber to the third party billing service, and if it is determined that the subscriber is a subscriber, this called subscriber number and the calling subscriber number received at the time of this incoming call are output to the called subscriber. It may be configured to include an exchange and a relay exchange that sends the information received from the called-end subscriber exchange to the service control point and sends charging destination information to the calling-end subscriber exchange based on the inquiry result.

2 is received to determine whether or not the incoming call is a call to which the called party billing service is applied and to output the result. A service control point (hereinafter referred to as SCP) 501 and an incoming subscriber number are received. It is determined whether or not this number is a subscriber who subscribes to the called party billing service. Based on the inquiry result, the charging destination information is sent to the calling LS 401 and the called-end subscriber exchange (Service) that functions as a service exchange point
Switching Point: Below, arrival LS (S
SP) and a name) 402. The arrival LS402 is I
N subsystem SSP function is installed, and INAP (IN Application) is used as an interface with SCP.
(Protocol) is used. In addition, as subscriber data, it has data that means that the subscriber is subscribed to this service.

Next, the call processing procedure and the registration / cancellation procedure of the subscriber to be charged for the called party will be described with reference to FIG. In this case, it is assumed that the subscriber 300 has contracted (subscribed) to the called party charging service, the subscriber 100 is the called party charging target, and the subscriber 200 is not registered.

First, when the subscriber 100 makes a call to the subscriber 300, the subscriber 30 at the destination LS 402.
It is judged from the subscriber data whether 0 is a subscriber to this service. Since the subscriber 300 is the service target, this call is treated as an IN call, and the initial call is made to the SCP 501.
Detection Point (Initial Dete)
action point (IDP) signal is transmitted. The IDP is a general IN call processing start operation, and is sent by the SSP to the SCP.

A database 5 attached to the SCP 501
From 02, it is verified whether the subscriber 100 has already been registered as a subscriber to be charged for the called party. As a result of verification, subscriber 1
00 has already been registered, so (SCP50
Guidance is sent to the subscriber 100 to notify that the billing is for the called party (by the instruction 1). Also, the result of the collation is notified from the SCP 501 to the destination LS (SSP) 402, and the destination LS 402 connects to the subscriber 300.
The destination LS 402 receives the response signal from the subscriber 300,
A parameter that explicitly indicates a called party billing call is set in the ANM signal transmitted to the preceding station.

On the other hand, the calling LS 401 receives the ANM signal indicating the billing for the called party and holds the information. Departure LS40
In No. 1, when the billing information is sent to the billing facility 700 after the call ends, the billing information including the payee subscriber (subscriber 300) is set and sent. The billing facility 700 performs processing so as to charge the subscriber 300 for the call charge of the main call.

Next, when the subscriber 200 makes a call to the subscriber 300, at the destination LS 402, the subscriber 300 is called.
It is judged from the subscriber data whether or not is a subscriber of this service. Since the subscriber 300 is a service target, this call is treated as an IN call and IDP is sent to the SCP 501.

The SCP 501 is an attached database 502.
As a result, it is verified whether the subscriber 200 has already been registered as a subscriber to be charged for the called party. As a result of the verification, the subscriber 200 is not the target, so the verification result is received from the SCP 501.
The S (SSP) 402 is notified. The following processing is performed as a normal call (call toll charged by the sender).

Next, when registering / deleting the subscriber to be charged by the called party, the subscriber 300 who contracts the service accesses the home page operated by the service provider by connecting to the Internet from his / her personal computer 302 or the like. I do. Connect to the IN equipment IGW502 via the Internet and perform additional registration / change / cancellation of data. The IGW 502 that has received the change updates the database 502 with respect to the SCP 501 at any time.

FIG. 2 is a signal sequence diagram of the first embodiment of the called party charging system of the present invention. The operation will be described in detail below with reference to FIG. Note that the various message signals in FIG. 2 are well known, and therefore their individual explanations are omitted.

In order to realize the callee billing system of the present invention, service registration is performed in advance by the destination LS 402.
Specifically, the maintenance person of the destination LS 402 registers the subscription to this service in the subscriber data for the subscriber number (XXX-XXXXXXX) of the subscriber 300. As the data, only the current subscription / non-subscription to the service can be determined, and the data size may be 1 byte. By performing this registration, when a call arrives at the subscriber 300, it can serve as an opportunity to activate a service to be described later at the destination LS 402.

First, the subscriber 100 sets 0XXX-XXX
When dialing XXX and making a call to the subscriber 300, the call is routed to the destination LS 402 accommodating the subscriber 300. The destination LS 402 uses the number dialed by the subscriber 100 (excluding the leading 0) as a key to verify the subscriber data possessed within the own station (process 1).
At the time of collation, the target data is the data indicating the subscription / non-subscription to the service.

As a result of the collation, the subscriber 300 (XXX-XX
When it is identified that (XXXX) is subscribed to this service, inquiry is made to SCP 501 as to whether the telephone number (YYY-YYYYYY) of the caller (subscriber 100) is registered as a subscriber to be billed for the called party. I do. At that time, the destination LS 402 makes an inquiry from the destination LS 402 to the SCP 501 by IDP operation of the INAP signal, and in the signal, a service key (identifying the awareness between SSP and SCP) that can be identified on the SCP side as an inquiry by this service, Information on the calling number (subscriber 100) and the called number (subscriber 300) is essential. Upon receiving the IDP operation, the SCP 501 identifies the service from the service key (process 2), and the SCP 501 issues a subsequent operation instruction to the destination LS 402.

In FIG. 2, as an example of service extension, since it was possible to identify from the inquiry result that the caller (subscriber 100) is a subscriber to be charged for the callee, "caller (subscriber 100)" The call charge for this call will be borne by the recipient. ”
An example in which the 501 issues an instruction to the destination LS 402 is shown. The CTR shown in FIG. 2 is Connect To
An abbreviation for Resource, which indicates a connection to a special resource to be used (assuming a sound source device here),
Is an abbreviation for Play Announcement, which indicates the guidance (announcement) to be connected, and indicates the type of the guidance, the sending time, the number of times, and the like. Also,
SRR is a Specialized Resource
Abbreviation of Report, showing the response to the above-mentioned PA,
When the sending of the guidance instructed on the PA is completed, SS
Notifying P to SCP.

CTR + PA is generally called a multi-component, and is a combination of a plurality of components in one signal unit. INAP is a transaction function application section (Transaction Ca
laboratories Application Pa
rt: TCAP) is a protocol located above.
Therefore, CTR + PA here means SCP
Although the number of signal units sent between the SSP and the SSP is one, the signal analysis at the INAP level results in two signals. CPG is a well-known ISUP signal name, and
It is an abbreviation for ll Progress message. The sequence of FIG. 2 shows an example in which guidance is connected before returning the ACM to the transmitting station. Therefore, it is necessary to first release the reverse call path that is normally opened by returning the ACM. Therefore, the destination LS (SSP) sends CPG in order to open a backward path when it receives CTR + PA from SCP.

Next, the SCP 501 notifies the destination LS 402 that the caller (subscriber 100) is a subscriber to be charged by the called party (process 3). In Figure 2, CNTWA
The (Continue With Argment) operation is instructed to continue the call processing, and the collation result is included in this operation and notified. LS4
02, upon receiving the CTNWA operation from the SCP 501, connects to the subscriber 300. Also,
Information on the charging destination for this call is stored in the destination LS 402 (process 4). When the response signal is received from the receiving side subscriber 300, the charging destination information stored in the process 4 is sent to the preceding station A
It is placed on the NM signal and notified to the originating LS 401 (process 5).
The calling LS 401 stores the charging destination information received in the process 5.

After the call is finished, the calling LS 401 displays the charging information (Call Detail Record: C below) of this call.
Created as (DR). At that time, the information stored in the process 5 is included in the CDR (process 6). Calling LS401 process 6
The CDR created in step 1 is sent to the billing facility 700. The billing facility 700 processes the CDR of the main call as a called party billing call according to the billing destination information.

FIG. 3 shows a processing flow in the personal computer 302. In the present embodiment, the connection to the Internet is described from the personal computer, but the connection is not limited to the personal computer, and other equivalent devices may be used.

First, start the browser from the personal computer,
Access the home page operated by this service provider via the Internet (step 20: referred to as S20, and so on). Log in on the login screen and enter the user ID (telephone number or the number provided by the service provider) and password (S21).

After successfully logging in (S22), the process desired to be executed is selected (S23). As options, display / change / delete / add / logoff registered data are prepared (S
25-S33).

When change / deletion / addition is selected in S25 to S33, a screen for inputting necessary information is displayed to prompt input. Check the input data for normality,
If it is NG, the NG screen is displayed and the input is prompted again. If the display is selected, the registered data is displayed (S2
4) If the logoff is selected, the login to the update processing is canceled (S34).

Next, FIG. 4 shows a processing flow when the called LS 402 handles this service call. FIG. 4 shows a case where the calling party 100 and the called party 300 are accommodated in different subscriber exchanges.

First, when the called LS 402 accepts a call (S40), it is determined whether the accepted call is an incoming call to a subscriber in the own station (S41). If YES, there is a possibility of being subject to this service, and the processing proceeds to the next process.

Next, the subscriber data is retrieved from the called number,
It is determined whether the called party 300 is a subscriber to this service (S43). In the case of YES, there is a possibility of being subject to this service, and the process proceeds to the next process. In the case of NO, it is not subject to this service and is processed as a normal call. When the called party 300 is a subscriber to this service, the SCP 501 is inquired as to whether the calling party is a billing party for the called party (S4).
4) The result is received and stored (S45).

The destination LS 402 connects to the subscriber 300 regardless of the inquiry result in S44 (S4).
6). However, when the SCP 501 instructs the disconnection, the instruction is followed. When a response signal is received from the callee (S4
7) Based on the information stored in S45, it is determined whether the billing destination for this call is the called party (S48). If YES, the process proceeds to the next process to notify the preceding station, and if NO, a normal call is processed. If the payee is the called party,
Edit the ANM signal including the fact that it is a call billed by the called party and issue the LS
It is sent to 401 (S49).

Next, the processing in the SCP 501 will be described with reference to FIG.

The IDP is received from the SSP (S50), and the service is identified by the service key of the received information (S50).
51). In S51, if it is another service, the corresponding IN service is started (S52), and if it is determined to be this service, the subscriber number to be charged to the called party is searched using the called number of the IDP operation as a key. (S53),
The presence or absence of the retrieved registration data is checked (S54).
If there is no data, a Continue operation is sent to the SSP to instruct to continue the call processing (S55), and if there is data, the process proceeds to the next process.

The search result and the calling number are collated (S56), and the presence or absence of matching data is checked (S57). If there is no data, SSP will
A "nue" operation is sent or the CNTWA operation is used to notify that the caller is charged, and an instruction to continue the call processing is given (S58). On the other hand, if there is data, the SSP notifies the SSP of the callee billing by CNTWA operation as the callee billing, and gives an instruction to continue the call processing (S59).

Referring to FIG. 6, there is shown a second embodiment of the called party charging system of the present invention. The system includes subscribers 100 and 200, an LS 401, a billing device 700, a subscriber 300 having a telephone terminal 301 and a personal computer 302, an IGW 601, and an SCP 501.
If the receiving subscriber number is received and it is judged that this number is a subscriber who has subscribed to the called party billing service and if it is determined that the subscriber is a subscriber, this called subscriber number and the outgoing call received at this incoming call LS 402 that outputs the subscriber number and LS
The receiver side repeater exchange TS (SSP) 403 functions as a service exchange point by transmitting the information received from the 402 to the SCP 501 and transmitting the charging destination information to the LS 401 based on the inquiry result. In this system, the functions other than the TS 403 are the same as those of the respective units shown in the first embodiment, and the description thereof will be omitted. TS403 is IN
The subsystem SSP function is installed, and INAP (IN Application P
rotocol) is used. In addition, the destination LS 402 has, as subscriber data, data indicating that the subscriber has subscribed to this service.

Next, the call processing procedure will be described with reference to FIG. In this case, the preconditions of the subscriber registration state are the same as those in the first embodiment, and thus the description thereof will be omitted.

First, when the subscriber 100 makes a call to the subscriber 300, the destination LS 402 connects the routed main call to the subscriber 300. Arrival LS402
Is a parameter for calling the subscriber 300, sending an ACM (address completion signal) to the preceding station, determining whether the subscriber 300 is the subscriber of this service from the subscriber data, and notifying that the subscriber is currently subscribed. Is included in the ACM that sends

Upon receiving this ACM, the TS (SSP) 403 treats this call as an IN call and the SCP 501
IDP is sent to In the SCP 501, it is verified from the attached database 502 whether the subscriber 100 has already been registered as a subscriber to be charged for the called party.

On the other hand, the destination LS 402 receives the response signal from the subscriber 300 and sends the ANM (response message) to the TS (SSP) 403. At this time TS (SSP) 403
Does not send ANM to the preceding station. The verification result is SCP5
From 01, the TS (SSP) 403 is notified, and the TS 403 sends the ANM to the preceding station. At that time, a parameter that explicitly indicates the call billed to the called party is set.

In the originating LS 401, the AN indicating the callee billing
It receives M and holds that information. Also, departure LS401
Then, when the billing information is transmitted to the billing facility 700 after the call ends, the billing information including the billed subscriber (subscriber 300) is set and transmitted. The billing facility 700 performs processing so as to charge the subscriber 300 for the call charge of the main call.

Next, when the subscriber 200 makes a call to the subscriber 300, the destination LS 402 connects the routed main call to the subscriber 300. The destination LS 402 calls the subscriber 300 and sends the ACM to the preceding station. Whether or not the subscriber 300 is a subscriber of this service is determined from the subscriber data, and a parameter notifying that the subscriber is currently subscribed is included in the ACM.

The TS (SSP) 403 treats this call as an IN call by receiving the above ACM, and the SCP5
IDP is sent to 01. The SCP 501 checks whether the subscriber 200 is already registered as a subscriber to be charged for the called party from the database 502 owned by the SCP 501. The destination LS 402 receives the response signal from the subscriber 300, and the TS
The ANM is sent to the (SSP) 403. At this time, TS (S
SP) 403 does not send ANM to the preceding station. As a result of the verification, the subscriber 200 is not a target, so the result of the verification is SC
The P (501) notifies the TS (SSP) 403. The following is processed as a normal call (call toll charged by the sender).

FIG. 7 is a signal sequence diagram of the second embodiment of the called party charging system of the present invention. The operation will be described in detail below with reference to FIG. 7.

First, the subscriber 100 sets 0XXX-XXX
When dialing XXX and making a call to the subscriber 300, the TS (SS
P) 403 to be routed. LS4
In 02, the subscriber is connected to the subscriber 300 (terminal 301), and the subscriber data possessed in the own station is collated using the number dialed by the subscriber 100 (excluding the leading 0) as a key (process 11). . As a result of verification, the subscriber 300 (XX
X-XXXXXXX) is subscribed to the service and includes the result in the ACM message sent to the preceding station.

The TS (SSP) 403 sends to the SCP 501 the telephone number (YYY-Y) of the caller (subscriber 100).
It is inquired whether YYYY) is registered as a subscriber to be charged for the called party (process 12). At that time, TS
The (SSP) 403 makes an inquiry to the SCP 501 by the IDP operation of the INAP signal, and in the signal, a service key (the awareness between the SSP and the SCP is matched) that can be identified on the SCP side as an inquiry by this service, Information on the calling number (subscriber 100) and the called number (subscriber 300) is essential. Upon receiving the IDP operation, the SCP 501 identifies the service from the service key and notifies the TS (SSP) 403 that the caller (subscriber 100) is a subscriber to be charged for the called party (process 13).

In FIG. 7, CNTWA (Continue)
In addition to instructing the call processing to be continued in the "With Argument" operation, the collation result is included in this operation and notified. TS (SSP) 403 is S
When the CNTWA operation is received from the CP 501, the collation result included in this operation is included in the ANM signal to be sent to the preceding station and notified to the originating LS 401 (process 14).

The calling LS 401 stores the charging destination information received in the process 14. After the call is completed, the originating LS 401 creates charging information (CDR) for this call. At that time, the stored charging destination information is included in the CDR (process 15). Departure LS
401 sends the CDR created in process 15 to the charging facility 700. The billing facility 700 processes the CDR of the main call as a called party billing call according to the billing destination information.

In the second embodiment, the destination LS does not have the SSP function (it may have the SSP function, but it is not used for carrying out the present service), and the switching device of the relay ladder has it. However, subscriber data for identifying subscription / non-subscription of this service is held by the destination LS as in the second embodiment. As a result, since the destination LS does not make an inquiry to the SCP, the load on the destination LS is reduced, and this service is also realized by operators who have only relay switching equipment other than the telecommunications carriers that accommodate subscribers. It becomes possible to do.
