CONSTITUTION: When a call is income(201), this income call is subjected to the authentication(202). An authentication process of the income call is carried out, and then the income call is processed normally if the authentication of the income call has been successful(203). If the authentication thereof has been failed, the authentication thereof is performed again(204). The income call is processed normally if the authentication thereof performed again has been successful(203). If the number of authentication tries exceeds a preset number, a call release procedure is carried out(205).

Description

Method of selective terminating call service using intelligent network

The present invention relates to a selective call service method that enables protection and privacy-oriented services of a called party in an intelligent network system, and a computer-readable recording medium having recorded thereon a program for realizing the method.

To date, there are no services that can protect subscribers from prank calls or telephone violence.

The general subscriber may not feel the need for this kind of service, but the provision of such a service is essential for a small number of subscribers suffering from violent calls. As a way to defend against such violent calls, the service is currently limited to subscribers registered to this function, called malicious call tracking. The telephone company can make outgoing calls through the call tracking function for all incoming calls to this subscriber. It will be recorded. At this time, the registered subscriber can find out the calling number used by the caller by contacting the telephone company after receiving the violent call.

However, when the caller uses a public telephone or a third party phone, such caller ID tracking cannot effectively protect the subscriber.

In another aspect, caller ID tracking may be an area of privacy violation. As a result, these subscribers have no choice but to change the phone number, which adds another inconvenience, such as having to announce a new phone number around them.

As such, there has conventionally been no service capable of selectively receiving incoming at the exchange level. However, there was a method to prohibit the incoming call itself or to change the cracking rate of the incoming bell so that the subscriber can recognize it. However, since the hearing perception ability of a person has a limitation in distinguishing the cracking rate, the existing service cannot be used.

For this purpose, when implementing an optional incoming call service as an additional service level of an existing exchange, first, an existing software block needs to be corrected and a new block for authentication needs to be added. In addition, at least three additional resources for providing announcements should be secured, but this is not an easy problem because the "ANU" device that provides announcements throughout the exchange is already limited. Moreover, even after the development is completed, it will take considerable time and money to apply it to the exchanges nationwide.

Therefore, through the implementation by intelligent network logic, an optional function is provided to authenticate only incoming calls as a way to prevent violent calls in advance without changing the software of the existing exchange and adding hardware devices. An incoming call service plan is required.

The present invention devised to meet the requirements as described above, only the call passing through this authentication by providing an authentication function for the incoming call to enable the protection and privacy-oriented services of the incoming subscriber in the intelligent network system It is an object of the present invention to provide a selective call service method and a computer readable recording medium having recorded thereon a program for realizing the method.

The present invention also provides a computer-readable recording medium having recorded thereon a program for realizing a sixth function of activating / deactivating the authentication procedure for each desired time period.

The present invention relates to a selective incoming call service method in which only a call passing through this authentication is provided with an authentication function for a call that is received as a method for preventing a violent call in advance. In addition, this method can be used for other purposes, as well as to prevent violent calls, since the call only reaches specific persons who pass authentication.

The present invention proposes an implementation by intelligent network logic, and proposes a method that can implement a function without changing the existing switch and adding a hardware device.

The proposed method additionally provides the following functions.

First, the called party can specify the calling number to be omitted first.

Second, the designated sender is immediately connected with the called party without authenticating.

Third, you can specify this service by time zone.

Fourth, since the called subscriber can designate a desired time for the service, the service can be used more efficiently.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration of a next generation intelligent network system to which the present invention is applied.

The Advanced Intelligent Network (AIN) service provides AIN devices with an intelligent network service by interworking with each other, and AIN can be classified into four functional entities in terms of service provision.

Looking at these functional entities, it performs a call control function (CCF) (22) and detects an intelligent network service from the basic call processing of the exchange and requests a service switching function (SSF) (12). ), A service control function (SCF) (11) for performing the requested intelligent network service, a specialized resource function (SRF) (31) for the user interface during service execution, and a service necessary for performing the service. There is a Service Data Function (SDF) 12 for managing data.

Each functional entity includes a service switching point (SSP) 20, a service control point (SCP) 10, an intelligent peripheral (IP) 30, and a service, which are physical entities. Each data system (SDP: Service Data Point) 12 is physically corresponding to and mounted.

Intelligent Network Application Protocol (INAP) is an application protocol for supporting signals required for interaction between next-generation AIN functional entities. It supports application layer interfaces between SCF-SSF, SCF-SRF, and SCF-SDF functional entities.

The intelligent network service can be supported by the interaction between functional entities. In order for the interaction to be successful, the intelligent network application protocol (INAP) that supports signals between the functional entities must be implemented according to the standard.

Next-generation intelligent network (AIN) devices to which the present invention is applied will be described in more detail AIN service that provides the intelligent network service to the subscriber in conjunction with each other.

When the call originated from the telephone terminal is transmitted to the intelligent network switch 20, which is an intelligent network device, the intelligent network switch 20 sends a service request message to the intelligent network switch 20 and the service control system 10 according to the caller's request to use the intelligent network service. ) Is transmitted to the service control system 20 in the next generation intelligent network application protocol (INAP) message through the interface between.

The service logic in the service control system 20 controls the service with reference to the profile of the service subscriber stored in the form of a database in the service data function 12. At this time, if additional information is required from the caller for service processing, the intelligent peripheral device 30 is connected to the interface to collect information from the caller.

When the service processing is completed and the service control system 10 loads the result in the intelligent network application protocol message and transmits the result to the intelligent network switch 20, the intelligent network switch 20 sends and receives the result data received from the service control system 10. Connect calls between telephone terminals or perform other supplementary services.

In the present embodiment, the service control system 10 is implemented in the local exchange itself to enable individual services to the general subscriber. At this time, since the local subscriber can selectively make the call, it can be appropriately used for subscriber protection and privacy. This will be described in more detail.

2 is a flowchart illustrating an exemplary embodiment of a selective call service method according to the present invention.

As shown in FIG. 2, in the selective incoming call service method according to the present invention, when a call is first introduced (201), the incoming call is authenticated (202), and the incoming call is normally processed when the authentication is successful. (203). If authentication fails, re-authentication is performed (204). If the re-authentication process is successful, the incoming call is processed normally (203). If the set number of times is exceeded, a call release procedure is performed (205).

3 is a service scenario at the time of authentication success in the selective incoming call service method according to the present invention, and shows an overall service scenario centering on successful authentication.

Since the selective call service method according to the present invention is an incoming call related service, the service is started in a termination basic call state model (BCSM).

First, the position where arming should be performed for triggering is placed in Term_Attempt_Authorized corresponding to DP (Detection Point) 12. That is, DP 12 is armed with TDP_R in DP data handling.

When the call arrives to the subscriber (301), the incoming BCSM reaches the DP point 12 by checking the status of the subscriber and whether or not the call can be received. Since this DP is armed with TDP_R, an "IDP (InitialDP)" message is sent to the SCF. 302. That is, the destination exchange stops the basic call processing operation when a call is received from the originating exchange, and searches for a DP condition and sends an IDP message to the SCF if it matches.

After receiving the IDP, the SCF sends a "ConnectToResource (CTR)" message to the destination exchange by including the "RRBE (RequestReportBCSMEvent)" message and routing information for the SRF connection in order to request the necessary event (303, 304). That is, the SCF receiving the IDP starts a service logic program (SLP) and requests a DP point to be reported to the SSF in the destination exchange.

The terminating exchange receiving the CTR message then routes to the SRF to connect a bearer between the SRF and the originating exchange (305). That is, the SSF in the destination exchange routes to the SRF and bearer setup is made.

Subsequently, the SCF sends a " PromptAndCollectUserInformation " message to the SRF to request collection of the corresponding announcement code and necessary information (306). After receiving the PCUI, the SRF sends the corresponding announcement to the calling exchange using the information in the message (307) to induce the input of the password corresponding to the authentication key.

After that, if there is no response for a certain time, the announcement is sent again. If there is no response after that, the SCF sends a "RC (ReleaseCall)" message to the destination exchange to release the call.

If the originating subscriber enters a password and receives a password from the originating exchange (308), the SRF sends a "Collect User Information (CUI)" message containing this input information to the SCF (309). At this time, SCF compares CUI password match and if it does not match, sends the PCUI with different announcement code to SRF so that SRF retries the authentication process. In step 310, a "DFC (DisconnectForwordConnection)" message is sent to the exchange.

Next, the destination exchange receiving the DFC notifies the SRF of the release processing (311), releases the bearer connection with the SRF (312), maintains the bearer channel with the originating exchange (313), and connects the ring to the called party ( 314). At this time, when the called person hooks off, the call is normally made. That is, the bearer channel connected between the SSF and the SRF in the terminating exchange is released, and a normal call connection is made during the terminating exchange period with the originating exchange.

On the other hand, if the password is retried again or the password is not entered within the specified time, this means that the authentication has failed and the call must be forcibly terminated.

4 is a service scenario when authentication fails in the selective incoming call service method according to the present invention, and illustrates a service scenario when authentication fails due to an input timeout during authentication, or an incorrect authentication key input.

First, when the SRF sends a "CUI (CollectUserInformation)" message containing input information to the SCF (401), the SCF sends a "PA (PlayAnnouncement)" message containing the announcement code for authentication failure to the SRF ( 402, the SRF informs the originating exchange of the authentication failure (403), and sends a Release Call (RC) message to the destination exchange (404) to release the bearer with the SRF and the bearer with the originating party (405, 406).

On the other hand, when the caller releases the call during authentication, the procedure of release of incoming subscriber and SRF by SCP is as follows.

5 is a service scenario when the subscriber is released during authentication in the selective call service method according to the present invention.

First, when the originating exchange requests the release to the destination exchange (501), the destination exchange sends a " CRP (CallInformationRePort) " message to the SCF (502). At this time, when the SCF sends a "RC (ReleaseCall)" message to the destination exchange (503), the destination exchange requests to disconnect from the SRF (504).

Since this service is based on the called party's position, it is true that it is troublesome for the caller that all incoming calls must be authenticated. In response, the called party may designate a specific calling number that is not authenticated. This authorized caller list is managed by the SCF. When the IDP is received, the caller's number is compared with the caller's number that is already entered. You can do it right away. It also allows the called party to adjust the service activation time.

As described above, the present invention allows the called party to selectively receive a call, thereby protecting the subscriber from unwanted incoming or violent calls. In addition, in terms of implementation, as a method by the intelligent network logic, the service scenario of the selective incoming call, the trigger position of the IDP and the arming condition were introduced. The implementation of this logic can be serviced by a combination of SCF and SRF logics, and the SSP can be serviced with just DP-related data handling. In addition, the service authentication logic of the present invention can be used in conjunction with other services. In addition, it is possible to determine whether or not to authenticate by the calling number so that it can be an efficient incoming service. In addition, by allowing the subscriber to specify the time at which the service is activated, a wider choice of service users can be provided.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention enables selective incoming call service using intelligent network technology, enables effective incoming service by placing an IDP location on the called party, and enables local subscribers to selectively make incoming calls. There is an effect that can be appropriately used in privacy.
