Abstract

PROBLEM TO BE SOLVED: To improve the reliability of data by executing the registering or the reading of credit information data to or from a data base when a subscriber is provided with the right of executing the providing service of credit information data. SOLUTION: When a call-originating person 10 originates a call, an exchange 1 investigates whether a call-incoming person is provided with the providing service executing right of credit information. When the call-incoming person 20 is provided with the right for executing 'credit information providing service' by judging subscriber's data, past data of the person 10 are accessed to the data base 40 holding and managing it by the call originating subscriber's number. Then information collected before in order to judge whether the call is a malicious call or another risky call, etc., is read out. After then, read information is transferred to the exchange. In this case, the subscriber's number of the subscriber 10 is retrieved as an access key to obtain credit information of the subscriber.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a credit information providing service system for storing credit information and providing it to subscribers as a service of an exchange system.

[0002]

2. Description of the Related Art In recent years, the social situation has been shifting to personalization of communications with the rapid development of multimedia and mobile phones. In such a situation, various services such as commerce using communication have become active. In this way, as the number of business transactions targeting a large number of service subscribers increases, some of them are malicious, which may cause inconvenience and property damage.

[0003] Therefore, it is desired to be able to provide subscriber credential information to a subscriber of a communication switching system as part of a switching service. As one of the subscriber credit information, information on whether or not the incoming call is the telephone number of a malicious call such as a prank call is provided, and a call rejection service (SCR) that rejects the incoming of the malicious call based on such information is provided. : SelectiveC
all Rejection) is provided.

As a specific example of such a call rejection service, for example, as described in Japanese Patent Application Laid-Open No. 4-51643, a special number from a called subscriber who has received a malicious call is used.
The calling party number that has received the malicious call is stored, and if it is confirmed that the call is from the same calling party number that is registered next time, the incoming of the malicious call is rejected.

[0005] Alternatively, as described in Japanese Patent Laid-Open Publication No. Hei 4-330841, when a receiver receiving a malicious call presses a specific button on a telephone, the central processing unit newly registers the malicious call in a malicious call list. I have to.

[0006] In a call rejection service (SCR: Selective Call Rejection) represented by such a method, FIG.
As shown in FIG. 0, each individual personally holds information on malicious subscribers in a database, and when an incoming call is received, the sender is compared with the database registered individually by the receiver. .

[0007] If it is determined that the communication is from a subscriber who wants to reject the incoming call, a service is provided such that the call is disconnected without receiving the incoming call. That is, in FIG. 30, (a) is a personal database for subscriber A,
(B) and (c) are personal databases for subscribers B and C.

[0008] In the personal database for subscriber A,
A registration to reject the incoming call from the subscriber X is made. In the personal database for the subscriber B, a registration to reject the incoming call from the subscriber Y is made. A registration to reject the call from Z is registered.

That is, taking subscriber A as an example, since subscriber A has received a malicious call by subscriber X in the past,
In the personal database as a subscriber who wants to reject the call,
The data of "subscriber number of subscriber X" is registered. However, regarding the subscribers Y and Z, there has been no contact in the past, and no data on those subscribers is available.

[0010] Therefore, in the case of communication from a subscriber who first arrives, that is, in the case of communication from an unregistered subscriber in the database of the called party, there is no data to be collated on the called side. Therefore, it is difficult for the called party to determine whether or not the communication is malicious.
As a result, a situation in which the called party who responds eventually suffers damage cannot be avoided.

For example, in the conventional processing shown in FIG. 31 when the subscriber database shown in FIG. 30 is used, the subscriber A receives an incoming call from the subscriber X (step
I), when the individual database of the subscriber A is searched, there is data of "call from the subscriber X is rejected". Therefore, the incoming call from the subscriber X is rejected or disconnected.

Next, when the subscriber A receives an incoming call from the normal subscriber O (step SII), there is no data indicating the possibility of a malicious call in the individual database of the subscriber O. Treated as an incoming call.

When there is an incoming call from the subscriber Y (step SIII), the individual database of the subscriber B has the data of "the incoming call from the subscriber Y is rejected", but is now searched. Since only the individual database of subscriber A is obtained, no information on the call from subscriber Y is registered. For this reason, the incoming call from the subscriber Y is processed as a normal incoming call. In such a case, subscriber A
In response to the call from the subscriber Y, there is a possibility of suffering damage.

[0014]

The subscriber of the credit information providing service can reject a call from the corresponding subscriber number or increase the alertness based on the credit information data.

Hereinafter, the provision and registration of credit information based on such a database will be described step by step. Currently, in an IN (Intelligent Network) service, information is transmitted and received between a database and an exchange node as shown in FIG. Specifically, a service such as a toll-free number is one example.

In the "credit information providing service" according to the present invention, transmission and reception of information between the database and the exchange node are
It can be performed using a similar method. In FIG.
The database 40 is located at a service control point 42. The database 40 is accessed by the exchange 1 through the common channel signaling network 3 to register and read data.

The transmission and reception of information between the database and the switching node shown in FIG. Necessary information is edited into the information element of Display in the message defined in 931 and the information is exchanged with the subscriber through the exchange or the database.

The information element of Display is CCIT
Recommendation T. Q. According to 931, it is for supplying display data displayed by the subscriber, and the information included in this information element is encoded with IA5 characters. For example, SE as a FORWARD direction message
AL as message in TUP, BACKWARD direction
TERING, CONNECT and RELEASE COMPLETE as a disconnection message.

Therefore, as an embodiment of the present invention, Di
The credit information can be provided by transferring the credit information on the spray information element.

FIG. 8 is a diagram for explaining an embodiment in which the credit information of the caller is provided at the time of connection within the local station as an application example of the present invention, and FIG. 9 is an operation sequence flow thereof.

When the caller 10 makes a call (step I),
In the exchange 1, it is checked whether or not the called party has the right to provide the credit information providing service (step II). Specifically, as described above with reference to FIG. 5, information as to whether or not the subscriber is currently subscribed to an additional service such as a call transfer service or a CALLWAITING service is held as subscriber data. Then, it is possible to determine what kind of additional service the subscriber has subscribed to and has the right to execute by checking the subscriber data.

Therefore, as described above, regarding the “credit information providing service” of the present invention, similarly to the above-mentioned additional service, the subscriber is included in this subscriber data.
By having information as to whether or not the subscriber is a "credit information providing service", it is determined whether the subscriber has the right to execute the "credit information providing service".

By judging the above subscriber data, if
If the called party 20 as the subscriber has the right to execute the “credit information providing service”, the past data of the calling party 10 is stored in the database 40 that holds and manages the calling party number using the calling subscriber number. to access.

Then, past collected information for determining whether the call is a malicious call or a call with a high risk is read. Thereafter, the read information is passed to the exchange (step III).

More specifically, when inquiring the database 40 about the credit information of the subscriber 10, the subscriber 10
By using the subscriber number of the subscriber as an access key, the credit information of the subscriber can be obtained.

Here, in the case of the caller's subscriber number, it is extracted from the information remaining on the control block of the switching node. Similarly, existing CLIP (power generation number display)
There is also a method of extracting the subscriber number of the caller from the control block of the terminal or the switching node by performing the service.

The information read to determine whether or not the call is a malicious call at the time of the incoming call is the SET information.
A message signal in the FORWARD direction such as UP is sent on the information element of the above-mentioned Display, and is notified to the called party (step IV).

More specifically, the credit information of the other subscriber sent on the information element of the Display is transmitted to the terminal or peripheral device by light, sound, voice, vibration, character display on a display, deformation, or the like. The notification is made to the called party by performing some kind of notification means.

The called party determines whether or not the call is a malicious call based on the information, and if the call is a malicious call and rejects the incoming call, the connection with the exchange 1 is cut off (step S1).
V) Then, the exchange 1 and the caller 10 are disconnected (step VI).

Next, FIG. 10 shows an application example of the present invention.
FIG. 11 is a diagram for describing an embodiment in which the credit information of the caller is provided in the case of inter-station connection, and FIG. 11 is an operation sequence flow thereof.

The caller 10 originates a call and requests a connection (SETU
P) to the exchange 1 (step I), the call information becomes
It is sent via the exchange 1 to the exchange 2 that accommodates the destination subscriber 20 (IAM: Initial Addresses).
s Message). Then, it is determined whether or not the called party 20 is a subscriber who has the right to execute the credit information providing service, as described above with reference to the embodiment of FIG. 8 (step II).

If the called party 20 has the right to provide the credit information providing service, the called party 20 accesses the database 40 that retains and manages the past data of the calling party 10, and uses the calling subscriber number to access the data. Information such as whether the call is a malicious call or a high-risk call is retrieved and read (step III).

Next, the receiver 20 is notified of the credit information of the sender 10 (step IV).
The credit information of the sender 10 can be used. Callee 20
Upon termination of the incoming call (step V),
The release request is sent from the exchange 2 to the exchange 1 (step VI). Then, the call of the caller 10 is disconnected by the exchange 1 (step VII).

FIG. 12 shows another embodiment to which the present invention is applied. In this embodiment, the caller's credit information is provided at the time of an incoming call so that the actual connection of the incoming call is not performed. FIG.
Is a corresponding operation sequence flow.

The caller 10 makes a call and requests a connection (SETU
P) to the exchange 1 (step I), the call information becomes
It is sent via the exchange 1 to the exchange 2 that accommodates the destination subscriber 20 (IAM: Initial Addresses).
s Message). Then, it is determined whether or not the called party 20 is a subscriber who has the right to execute the credit information providing service, as described above with reference to the embodiment of FIG. 8 (step II).

If the called party 20 has the right to execute the credit information providing service, the called party 20 accesses the database 40 that retains and manages the past data of the calling party 10, and uses the calling subscriber number to access the data. Information such as whether the call is a malicious call or a high-risk call is retrieved and read (step III).

Here, the sender 10
Is determined to be a Service-to-Self, the receiver 20 is disconnected without receiving the call of the sender 10 (step I).
V). Therefore, a release request is sent from the exchange 2 to the exchange 1 (step VI). Next, the call of the caller 10 is disconnected by the exchange 1 (step VII).

In the embodiment described so far, the credit information of the sender is exclusively provided to the called party. On the contrary, when applying for purchase of goods or the like by telephone, the other party, that is, the called party is called. There is a case where the sender wants to obtain credit information of the sender. An embodiment of the present invention corresponding to such a case will be described below.

FIG. 14 is an operation sequence flow for explaining an embodiment in such a case. Now, consider a case where the caller 10 is accommodated in the exchange 1 and obtains the credit information of the callee 20. A connection request (SETUP) is sent from the caller 10 to the exchange 1 (step). The exchange 1 sends this to the called party 20 (step I-1).

The exchange 1 checks whether or not the sender 10 has the right to execute the credit information providing service (step II). If the sender 10 has the right to perform the credit information providing service, the receiver 2
The past data of 0 is accessed to the database 40 that is held and managed, and information such as whether or not the called party 20 is a malicious subscriber is read (step III).

Since the subscriber number of the called party 20 is required for actual routing, and exists on the block of the switching node, it is used to inquire the database 40. If the terminal has a redial function, the subscriber number of the called party 20 can be known from the terminal of the calling party 10 itself, and the database 40 can be queried accordingly.

As described above, the found credit information of the called party is transmitted to the sender 10 by the information element such as DISPLAY of the BACKWORD signal such as CALPRO or ALERT.
(Step IV). Thereby, the caller 10
In this case, it is possible to avoid receiving the damage without knowing that the called party 20 is a malicious subscriber and making a contract such as purchasing an article.

FIG. 15 is an operation sequence flow for explaining still another embodiment according to the present invention, and is an operation example in which the sender's connection request (SETUP) is used to provide the sender's credit information to the other party's called party. is there.

When the caller 10 makes a call (step I),
The exchange 1 checks whether or not the sender 10 has the right to execute the credit information providing service (step II). If the sender 10 has the right, the sender 10 accesses the database 40 that retains and manages the past data of the sender 10 and determines whether the sender 10 is a malicious subscriber. Is read (step III).

The read information is stored in a DISPLA of a message in the FORWARD direction (eg, SETUP to the called party).
A notification is made to the called party 20 on an information element such as Y (step IV). Therefore, the sender 10 can actively notify the receiver 20 of his / her credit, and can be advantageously used for transactions and the like.

Here, the registration of the credit information (the Service-to-Self) will be described. If a method is adopted in which a malicious subscriber is registered at all times when a malicious subscriber is registered, a situation may occur in which a wrong subscriber is registered as a malicious subscriber even though it is a good subscriber.

In order to prevent such a situation, a malicious subscriber can be registered only during a call (CO in a normal sequence).
(After the NN message) or a method of limiting the time within a certain time after the disconnection.

If the subscriber is a subscriber of the credit information providing service, the exchange accepts the credit information registration message (REGIST) in the same way as the existing ALERTING message wait timer or the like.
ER) A wait timer is set, the call control block is held during that time, and the call control block is released when a registration message arrives or when a timeout occurs.

FIG. 16 shows an example of a sequence for notifying and registering malicious subscriber information to the database 40. The basic sequence operation can use the procedure of Q932 of CCITT. In the embodiment of FIG.
This will be described by taking as an example a sequence during which the timer for waiting for a credit information registration message after disconnection is in operation.

The subscriber 10 notifies the database 40 of the subscriber number of the malicious subscriber and the complaint item through the exchange 1 by operating the keys of the terminal or the like as in the case of registering the existing additional service. . The notified database 40
The signal information is registered by the subscriber number of the malicious subscriber.

Here, there are the following two methods for automatically reading the malicious subscriber number when notifying the subscriber number of the malicious subscriber.

The first case is where the subscriber number of a malicious subscriber (communication partner) is stored in the terminal. On the caller side, the number stored in the terminal by the redial function etc.
On the other hand, the receiver can store the subscriber number notified by the CLIP (power generation number display) service or the like in the terminal, so that when a malicious call registration procedure is performed by the subscriber, it is automatically performed. The terminal reads out the subscriber number of the communication partner, and
The exchange is notified in the ISTER message.

Second, a malicious subscriber (communication partner) is provided to the exchange.
Is stored in advance. The exchange normally stores information necessary for performing the exchange processing in a call control block. Therefore, REGIST is provided to the exchange.
When the ER message is received, the subscriber number of the other party is read from the corresponding call control block, and the subscriber number is registered in REG.
The notification is carried in the ISTER message.

That is, FIG. 17 shows the contents of the call control block of the call control processor 7 in the exchange 1, and the credit information registration reception flag * in the additional service information section of this block.
2 is set when a subscriber applies for registration of malicious subscriber information.

FIG. 18 is a processing sequence for further registering such credit information. The subscriber 10 requests the exchange 1 for registration of malicious subscriber information (step I).
On the other hand, exchange 1 determines whether or not the credit information registration acceptance flag * 2 is set in the call control block of FIG. 17 (step II). If the credit information registration acceptance flag * 2 is set, the subscriber is notified that registration has been completed in order to avoid re-registration (step II).
I).

On the other hand, if the credit information registration reception flag * 2 is not set, the credit information registration reception flag * 2 is set in the additional service information section of the call processing control block (step IV), and the malicious call subscriber is set. Call number (step
V), register in the subscriber data table (step V
I).

Next, a registration response is returned to the exchange 1 (step VII), and the exchange 1 notifies the subscriber 10 that registration has been completed (step III).

As described above, the call control block in the exchange has the credit information registration acceptance flag,
Control is performed so that a malicious call can be registered only once for one call. Actually, if a subscriber receives a credit information registration message (INFO) from the subscriber to the exchange during a call, it is determined whether or not registration has been completed by referring to the flag. Is set, a registered flag is set, and if registered, the subsequent registration message is controlled to be rejected.

Here, in each of the above embodiments, the description has been given of the credit information providing service when communicating with the other party. However, when the subscriber wants to obtain only the credential information without communication with the other party. There is. FIG. 19 is a block diagram of an embodiment corresponding to such a request, and FIG. 20 is a processing sequence flow thereof.

The subscriber 10 activates the inquiry function of the credit information providing service and inputs the number of the subscriber who wants to know (step I). The exchange 1 checks whether the subscriber 10 has the right to execute the credit information providing service (step II), and if the subscriber has the right and inquires to read the credit information, (Step II-1) Access the database 40 and read the credit information of the subscriber number that you want to know (Step II)
I). Next, the read information is notified to the subscriber 10 (step IV).

Here, the subscriber is selected by registering information indicating whether or not to provide the credit information on the subscriber data by using a service execution start message or a service execution stop message.

Therefore, when exchange processing is performed by the exchange 1, the registration data on the subscriber data is checked to determine whether to notify or not to provide credit information, and the subsequent processing is determined.

FIG. 21 is a block diagram showing a system configuration when the credit information database 40 is installed in the exchange. In the above-described embodiments, the credit information database 40 is provided outside, and is exclusively for inter-office connection. On the other hand, in the case of the intra-office connection as shown in FIG. 21, the difference is that the credit information database 40 is installed in the exchange, but the other operation explanations and function explanations are respectively described above. Since the third embodiment is the same as the first embodiment, further description is omitted.

The present invention can be applied to a larger system. FIG. 2 shows an embodiment in such a case.
2 will be described.

In FIG. 22, a telephone communication network 100 is a network that has exchanges 1 and 2 and performs telephone service, and a credit information providing system 200 having a credit information database.
And a common line signal network 3. Subscriber 10,
20 is interfaced with the credit information providing system 200 through a communication infrastructure 300 such as the Internet or a pager network 400.

Accordingly, there are a case where the credit information to the subscribers 10 and 20 is provided through the communication infrastructure 300 and a case where the credit information is provided through the telephone communication network 100. Regarding the latter, the same operation as in each of the above-described embodiments or the former communication infrastructure function can be considered to be integrated with the telephone communication network, so that further description is omitted here.

The operation will be described below only for the former. FIG. 23 shows a system for providing a credit information providing system 200 from an exchange.
FIG. 6 is a diagram for describing an embodiment in the case of cooperating with a server.

First, the subscriber 10 makes a call (step
I). The exchange 1 determines the credit information provision service license stored in the subscriber data of the called party, and accesses the credit information system to which the called subscriber subscribes using the subscriber number as key information (step). II).

The credit information providing system 200 has a database 40, and reads out the credit information of the corresponding subscriber from the database 40 in the same manner as in the above-described embodiment (step III).

The credit information providing system 200 communicates with the service subscriber via the communication infrastructure 300 by the notifying means already designated by the service subscriber (this information is also stored as the subscriber data of the service subscriber). To the credit information (step IV).

FIG. 24 is a diagram for explaining an embodiment in which the receiving side cooperates with the credit information providing system 200.

The subscriber makes a call (step I) and receives a call to the called party (step II). If any subscriber (subscriber 20 in FIG. 24) in the communication has the right to execute the credit information providing service, the credit information system 200 is assigned the subscriber number of the subscriber to be checked. To search for credit information and have it sent (step III). The connection between the systems including the exchanges 1 and 2 is the same as that described above, and the description thereof will not be repeated.

FIG. 25 is a diagram illustrating an embodiment in which the present invention is applied to a credit information providing service in a mobile communication system, and particularly illustrates the provision of credit information from home network A.

When the mobile station 30 roams in the home network B, a home location register HLR (Home Locala) for storing subscriber location information in the home network A is provided.
update the position information of the “Tion Register”.
The location information referred to here is the network B in the PDC system.
Gate position register GLR (Gate Locati)
on Register), and corresponds to the roaming number (RON) assigned to the Roman subscriber (roaming subscriber) notified to the home location register HLR of the home network A.

Further, in the GSM system, this corresponds to a routing number (MSRN) assigned to the Roman subscriber, which is notified from the gate location register GLR of the network B to the home location register HLR of the home network A. .

In this system, an incoming call from a malicious person to the mobile device 30 is connected to the home network A (step I). The exchange 1 inquires of the home location register HLR to obtain the location information of the mobile device 30 (step II).

The exchange 1 which has received the response to the inquiry about the location information from the home location register HLR determines whether or not the mobile device 30 is carrying out a credit information providing service (step III). If the credit information providing service is being executed, the exchange 1 inquires the database 40 of the credit information of the subscriber to be checked (step IV).

The exchange 1 notifies the read credit information in an IAM message to the exchange 2 (step V). The exchange 2 that has received the IAM message inquires of the gate position register GLR about incoming information (step VI). The exchange 2 that has obtained the incoming information performs a normal incoming process to the mobile device 30 via the base station 21 (step VI).
I). In sending the SETUP message to the mobile device 30 in the incoming call process, the received credential on the IAM is sent on the SETUP. Thereby, the credit information is notified to the mobile device 30 (step VIII).

FIG. 26 is a diagram illustrating an embodiment in which a mobile communication system provides credit information from outside the country. In such a system, the Service-to-Self service will
The incoming call to 0 is connected to the home network A (step I). The exchange 1 inquires of the home location register HLR to obtain the location information of the mobile device 30 (step II).

The exchange 1 notifies the home location register HLR of the contents of the inquiry in an IAM message to the exchange 2 (step V). The exchange 2 receiving the IAM message makes an inquiry to the gate position register GLR to obtain the incoming information of the mobile station 30 (step V).
I).

The exchange 2 having received the incoming information determines whether or not the credit information providing service is being executed, and if so, reads out the credit information of the subscriber who wants to know from the database 40 (step IX).

Thereafter, the incoming call processing is normally performed (step VII), and the credit information already obtained at the time of sending the SETUP to the mobile station is sent on the SETUP. Thereby, the credit information is notified to the mobile device (step VII).
I).

The feature of the embodiment shown in FIG.
The difference from the fifth embodiment is that the inquiry is made to the database 40 of the other network during the incoming call processing without being performed from the home network.

Here, the evaluation of the serviceability of the credit information providing service is one of the important factors depending on how many pieces of the subscriber's credit information are available. That is, in order to improve the serviceability of the credit information providing service, it is necessary to have the credit information of as many subscribers as possible.

In practice, a common database should be limited to only a limited range of subscriber data. For example, it is considered that only a report of a malicious call from a subscriber in the network or only a report from a service subscriber is made.

Here, if the credit information is transferred between networks or between systems, the collection range of the credit information is expanded, which is equivalent to an improvement in the data accommodating capacity.

Accordingly, an embodiment for transferring credit information between databases according to the present invention will be described below.

FIG. 27 is an operation sequence flow of an embodiment for inquiring of credit information between databases. If a credit information inquiry request comes to one database A (step I), if the corresponding credit information does not exist in its own database A (step II), a system with which the business is affiliated is determined in advance (step III). An inquiry is made to the database B of the system for credit information (step IV).

Database B, which has received the credit information inquiry between the systems, determines whether the request is from a business partner (step V). If there is a business alliance, search its own database (step VI). As a result of the search, if the corresponding data exists, the retrieved credit information is directly added (step VII). If the corresponding data does not exist, an error is set as in the case of no business alliance (step VII). VIII) Respond to the inter-system credit information inquiry (step IX).

The database A, which has received the inter-system credit information inquiry response, adds and updates the data in its own database (step X) and sends the credit information to the inquiry request source. As a result, the amount of information in the database gradually increases, and the service improves.

When the credit information is transferred between such databases, a security problem arises. FIG.
FIG. 9 is a diagram for describing an embodiment of transferring trust information between databases in consideration of security.

Transfer of credit information is performed between a first system including the exchange A and the corresponding credit information database A and a second system including the exchange B and the corresponding trust information database B. That is, in the first system, the exchange A accesses the database A (step SI), and the credit information is read (step SI).
I).

The read credit information is then transferred to the second system (Step III), and is copied and written to the database B by the exchange B (Step IV). At this time, the credit information sent from the first system to the second system, that is, the exchange of the credit information between the business companies, etc., is performed by using a cryptographic algorithm and an encryption key known by the subscriber in a database. By encrypting A,
Make sure that credit information is not stolen.

Further, when a service alliance is made between the operators, the credit information can be used in the database B by transferring the encryption key between the operators.

FIG. 29 is a view for explaining an embodiment of transfer of credit information in the inter-enterprise database. In FIG. 29, a company having exchange A and database A,
When an alliance is established between the exchange B and the operator having the database B, the credit information is transferred from the database A to the database B by a command of a database administrator or the like.

For example, when new credit information is accumulated in the database A, the credit information is transferred to the database B of the affiliated business operator. Thus, the credit information can be shared among the plurality of businesses.

In each of the above embodiments, if the degree of malice of a certain subscriber becomes high enough to make a complaint many times in the past and the call cannot be transmitted, the latest malicious call is taken as a remedy means. It is also possible to reset the credit information or reduce the degree of maliciousness if no malicious call is performed for a certain period (for example, one month) from the implementation date, that is, if no complaint such as malicious call registration or the like is received. It is.

[0131]

As described according to the above embodiments, by implementing the "credit information providing service" of the present invention, whether the call is a malicious call before the called party answers. You can find out quite accurately.

Also, it is possible to obtain credit information in advance for a call that has been received for the first time. If the service subscriber is a credible subscriber (who has not been bad in communication in the past), it is also possible to notify the other party of the fact and let the other party respond with confidence. Further, when a call is transmitted, the receiver information can be checked to see whether the communication partner is a trusted partner.

In view of the above, by using a database that can be used in common by all subscribers, the general reliability and credibility of the sender can be notified.
It is difficult to make a bad call, and such malicious mischief can be expected to disappear from society.
