Description

Method and system for providing notification message services of call forwarding}

The present invention relates to a call forwarding service processing technology in a communication system, and more particularly, to a service for transmitting call forwarding registration and release status information to a user during a forwarding service.

With the recent rapid development of electronic engineering and communication engineering, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data processing technology, people can use not only voice calls but also Internet access, video communication and video message transmission using mobile communication terminals. In addition, due to the rapid dissemination of mobile communication terminals, mobile communication terminals have become an essential means of communication in modern life, such as a considerable amount of communication occurring in human relationships through mobile communication terminals.

With the increase in the use of portable terminals, the use forms are becoming very diversified. Among various forms of use of such portable terminals, incoming calls and short messages (SMS) may be prohibited or switched to other portable terminals. This call forwarding or call forwarding can be caused by several reasons. For example, when the mobile terminal subscriber does not pay the usage fee properly, the mobile communication service provider may prohibit the reception of the call signal and the short message for the mobile terminal. In addition, the mobile terminal subscriber may request that the incoming call is prohibited in order not to use the mobile terminal for a specific period or to use only the calling function.

In addition, the mobile terminal subscriber may apply for call forwarding so that the call signal and the short message do not reach the mobile terminal of the mobile terminal, but instead arrive at another mobile terminal. For example, a parent may send a mobile terminal to a child while receiving a call signal or a short message that is received by the child's mobile terminal. Alternatively, when the mobile terminal subscriber cannot use the mobile terminal for a certain period of time, the incoming call can be transferred to the mobile terminal of another family.

Among such call forwarding services, when a call forwarding request or a release request of a mobile terminal subscriber is performed, a service for transmitting a notification message regarding a service registration and release status to a corresponding subscriber through SMS or the like is implemented. In the conventional call forwarding notification message service, a call forwarding service for a call forwarding request terminal is already performed when the corresponding service registration notification message is transmitted after the call forwarding registration is transmitted, and the corresponding message is transmitted only to the call forwarding terminal. In addition, even when the call forwarding release notification message is transmitted, the message is transmitted after the call forwarding is released, and the message is transmitted only to the call forwarding release request terminal.

Thus, there is an increasing number of cases of illegally using the call forwarding service by using the problem that the call forwarding notification message is transmitted only to one terminal, such as the terminal before the call forwarding or the terminal after the call forwarding. That is, through the conventional call forwarding notification service, the call forwarding fact can be known only from the terminal after the call forwarding when the call forwarding request is made, and there is a problem that the call forwarding service can be abused by the terminal user.

The intelligent network 100 is an intelligent network service providing node dedicated to additional additional service processing of a mobile communication system. The intelligent network 100 is a call forwarding request terminal and a call forwarding target terminal only for a call forwarding notification message service target subscriber during call forwarding setup registration and release processing. The service performs a process of transmitting a call forwarding notification message.

The intelligent network 100 provides a call forwarding notification message service in conjunction with the home location register 200 and the message center 300, and a detailed description of the intelligent network 100 device will be described later with reference to additional drawings. Shall be.

The home location register 200 performs location registration processing and location inquiry processing of the mobile communication terminals, and stores and manages subscriber profile information such as information on whether to subscribe to additional service of the mobile communication terminal subscriber. In addition, the home location register 200 performs call forwarding setting registration and release processing according to call forwarding requests from mobile communication terminals or the customer center 400. Call forwarding setting registration processing is a service registration process for converting an incoming call to a call forwarding request terminal to a call forwarding target terminal according to a call forwarding request. In addition, the call forward release processing is a process of canceling the call forward setting registration situation according to the call forward release request in the call forward setting registration state.

In addition, the home location register 200, after the call forwarding service setting registration and release processing, and confirms whether the user subscribed to the call forwarding notification message service, if the user subscribed to the service to indicate the call forwarding notification message additional service It serves to transmit a signal to the intelligent network (100). Through this, the intelligent network 100 is induced to provide a call forwarding notification message service. In addition, the call forwarding request and release request signal received by the home location register 200 includes information of the call forwarding request terminal and the information of the call forwarding target terminal.

In addition, the call forwarding request and release signal may be directly received through the mobile communication terminal 500 or may be received through the customer center 400. When the direct call transfer request signal is received through the mobile communication terminal 500, the service request signal is received through a special number or a service code input from the mobile communication terminal. When the call forwarding request signal is received through the customer center 400, the terminal user requests a service request from the customer center 400, and the call forwarding request signal is transmitted from the customer center to the home location register 200 according to the service request. Will be sent to process.

The message center 300 relays or transmits a short message (SMS) or a multimedia message (MMS) provided by a mobile communication system. In addition, the message center 300 inquires the location of the terminal to the home location register 200 according to the call forwarding notification message transmission instruction in the intelligent network 100, and performs a process of transmitting the corresponding message. In this case, the notification message transmission instruction information may include a message transmission instruction details to both the call forwarding request terminal and the call forwarding target terminal, and transmits the message to both terminals according to the information of the corresponding terminal. In addition, during the call forwarding setup registration process, after the notification message transmission instruction information is received, the home location register 200 may check the location confirmation and the additional service information of the terminals and transmit the message to both terminals.

In this case, the message center 300 transmits and processes the requested notification message to both terminals in conjunction with a value added server (VAS) when processing a message transmission according to a call forward notification message transmission instruction. That is, after confirming the location information through the information of the terminal to the call forwarding request terminal, and transmits a call forwarding notification message, the call forwarding target terminal delivers the notification message to the VAS, the call forwarding target terminal from the VAS After receiving the message transmission request for the location check to the home location register, and proceeds to the process of transmitting the message to the target terminal.

The customer center 400 serves to process service complaints of the mobile communication service subscription customers. The customer center 400 performs a service subscription, change and termination process for customers. When the customer center 400 receives a call forwarding setting request and a release request complaint from a call forwarding service subscription customer, the customer center 400 may serve to transmit a signal for requesting the call forwarding service processing to the home location register 200. . In addition, the customer center 400 may perform a subscription processing of the call forwarding notification service together with the call forwarding service. The call forwarding notification service is a service for notifying service processing result information when a call forwarding setting is registered and released as a message. The call forwarding notification message service according to the present invention provides a notification message to both a call forwarding request terminal and a call forwarding target terminal. Provides a service for sending.

The plurality of mobile communication terminals 500 are communication terminal devices that receive a mobile communication service through a communication network, and may correspond to various terminal devices such as a mobile phone, a cellular phone, a PDA phone, and a smart phone. In addition, the mobile communication terminal 500 may request a call forwarding service, and when a call forwarding request is requested from terminal # 1 to terminal # 2, the mobile communication terminal 500 transmits a call forwarding request signal from terminal # 1 to terminal # 2. In this case, the service may be requested through the customer center 400, or the service may be requested by directly transmitting a call forwarding request signal from # 1 to # 2 through a terminal.

When the service according to the call forwarding request from the # 1 terminal to the # 2 terminal is registered, the call received from the # 1 terminal is switched to the # 2 terminal and the call is received. In addition, according to the call forwarding notification service according to the present invention, a notification message is transmitted to both # 1 terminal and # 2 terminal as call forward processing result information during call forwarding processing.

2 is a diagram showing the configuration of a call forward notification message service providing apparatus according to an embodiment of the present invention.

2, the call forwarding notification message service providing apparatus 100 according to the present invention is mounted on an intelligent network located in a core network of a mobile communication system to provide a notification message service, and a signal receiving module 110 and terminal information. Extraction module 120, notification message transmission control module 130 and the like.

The signal receiving module 110 serves to receive a call forwarding notification additional service processing instruction signal after the call forwarding setting registration and release processing in the home location register. The signal reception module 110 receives a signal including information of a call forwarding request terminal and information of a call forwarding target terminal when receiving a call forwarding notification additional service processing instruction signal.

The terminal information extracting module 120 analyzes the call forwarding notification additional service processing instruction signal received through the signal receiving module 110 and extracts the information of the call forwarding request terminal and the information of the call forwarding target terminal included in the signal. It performs the role of extraction.

The notification message transmission control module 130 processes notification message transmission to the call forwarding request terminal and the call forwarding target terminal based on the call forwarding request terminal information and the call forwarding target terminal information extracted through the terminal information extraction module 120. Serves to control. In the message transmission control, a message transmission control process is performed by transmitting a message transmission control signal to the message center 300. That is, the notification message transmission control module 130 instructs the message center 300 to transmit a call forwarding notification message to both terminals based on the information of the extracted request terminal and the target terminal. At this time, the message transmission instruction processing is performed by transmitting the content information of the notification message and the information of both terminals to which the message is to be received. Alternatively, in the case of notification message transmission processing according to the call forwarding setting registration, the content information of the notification message and the notification message transmission signal are transmitted to the message center 300 through parameters, thereby causing the message center 300 to perform the home location register 200. ) To check the information of the terminal, and through this it can be sent to the notification message to both terminals.

In this manner, a notification message informing of the call forwarding fact is transmitted to both the call forwarding request terminal and the call forwarding target terminal during the call forwarding process.

3 is a flowchart illustrating a method of providing a call forwarding notification message service according to an embodiment of the present invention.

Referring to FIG. 3, first, a procedure of receiving a call forwarding request or a call forwarding release request signal is performed. Here, the call forwarding request or release request signal may be received from the mobile communication terminal, or may be received through the customer center. In addition, the call forwarding request signal includes information of the call forwarding request terminal and information of the call forwarding target terminal. That is, when the call forwarding request terminal is the # 1 terminal and the call forwarding target terminal is the # 2 terminal, the call forwarding request signal includes information of the # 1 and # 2 terminals, indicating that the call forwarding request is from # 1 to # 2. Information may also be included. In addition, such a call forwarding request or release request signal reception may be made in the home location register of the mobile communication system (S10).

Next, when a call forwarding request or call forwarding release request signal is received, a procedure for performing call forwarding service setting and deregistration processing is performed. First, in the case of a call forwarding request signal, a call forwarding setting process is performed from the call request terminal to the call destination terminal. In the case of the release request signal, a procedure of releasing the setting information which has been set up for call forwarding is performed.

When the call forwarding setting and release processing is performed in this way, the setup registration processing is performed such that the call to # 1 is switched to # 2 in the call processing information of the terminals. That is, when a call is requested to the # 1 terminal, the call is transferred to the # 2 terminal. In the release processing, the call forwarding setting registration information from # 1 to # 2 is deleted, and when the call is received from the # 1 terminal, the call is received at the # 1 terminal as it is (S30).

With this call forwarding process, a procedure for checking whether a call forwarding request subscriber is subscribed to the call forwarding notification additional service is performed. The confirmation of the call forwarding notification additional service subscription is confirmed through the additional service information stored in the subscriber profile in the home location register. That is, it is checked whether the user is subscribed to the call forwarding notification additional service in the stored subscriber profile through the subscriber information of the call forwarding request terminal. In addition, the call forwarding process and the process of confirming the subscription of the additional service as described above may be performed in the home location register.

As a result of checking whether the service is subscribed, when it is determined that the call forwarding notification additional user is subscribed to the service, a procedure of extracting identification information of the call forwarding request terminal (# 1 terminal) and the call forwarding target terminal (# 2 terminal). Is done. In addition, in the case of the call forward release processing, identification information of the call forward release request terminal and the call forward release target terminal is extracted.

When the information of both terminals is extracted in this way, a procedure is performed to transmit a call forwarding notification message to each of the terminals # 1 and # 2 through the message center based on the terminal information. At this time, the call forwarding notification message includes call forwarding setting registration situation or call forwarding release situation. As described above, the call forwarding notification additional service processing procedure of extracting terminal identification information and controlling to transmit a message to each terminal may be performed in an intelligent network.

At this time, in the case of the call forwarding setting registration process, only the parameter for transmitting the call forwarding notification message to the message center is transmitted and the signal is transmitted, and the message center checks the additional service with the home location register according to the promised parameter. Also, the terminal # 1 and # 2 may check the information and may process to transmit a notification message to both terminals.

On the other hand, as a result of confirming whether or not to subscribe to the call forwarding notification additional service, if the subscriber does not subscribe to the notification service, the procedure may be terminated as it is after the call forwarding service is processed. That is, a procedure of ending the call forwarding process without notifying the call forwarding result by the message or transmitting the call forwarding result guide message only to the call forwarding target terminal after the call forwarding may be performed according to the conventional call forwarding result message guide service. This is to provide a call forwarding notification service according to the present invention only to the service subscriber in the operator side.

Through the above-described processing procedures, the call forwarding notification message is transmitted to both the call forwarding request terminal and the call forwarding target terminal when the call forwarding service is processed, thereby preventing the problem of abuse of the call forwarding service in advance and attempting to exploit the service. Provides the effect of reducing

4 is a diagram illustrating a signal processing flow performed at each node of a communication system according to a method of providing a call forwarding notification message service according to an embodiment of the present invention.

First, in this embodiment, suppose that the terminal # 1 requests the call forwarding setup to the terminal # 2, and accordingly, the call forwarding notification message is transmitted to both terminals (# 1 and # 2) along with the call forwarding process. Explain.

According to the above assumption, the terminal # 1 is a procedure for requesting a call forward to the terminal # 2. In this case, the terminal # 1 may directly request a call forwarding from the home location register, or the terminal # 1 may request a call forwarding request through the customer center. (1)

In the case of requesting a call forwarding to the customer center, upon request of the terminal # 1, the customer center proceeds to request a call forwarding from the # 1 terminal to the # 2 terminal with the home location register.

The home location register sets and processes the call forwarding service according to the call forwarding request, and stores the forwarding service in the call forwarding information for the # 1 terminal to be forwarded to the # 2 terminal.

After the home location register processes the call forwarding setting process, the home location register proceeds to check whether the subscriber who requested the call forwarding is subscribed to the additional service. The additional service to check at this time is a call forwarding notification additional service.

As a result of confirming the additional service, if the user terminal is subscribed to the call forwarding notification additional service, a procedure for transmitting the call forwarding notification additional service processing instruction is performed to the intelligent network system. In this case, since the call forwarding service is set and registered, the content of the additional service is changed, and thus the signal is transmitted to the intelligent network in the form of the additional service change notification message.

In the intelligent network system, upon receiving the call forwarding notification additional service processing instruction or the additional service change notification message from the home location register, the intelligent network system checks whether the call forwarding setting registration processing or the call forwarding cancellation processing is performed. A procedure of instructing the SMSC to transmit a call forwarding notification message to each terminal is performed. At this time, when the message transmission instruction to the message center, it is indicated by the call_FWD_Alert parameter setting in advance. (6)

The message center receives the notification message transmission instruction from the intelligent network system, and proceeds to process the notification message transmission to both terminals according to the instruction. Of course, the message transmission indication may be received from the intelligent network system through the Call_FWD_Alert parameter setting. At this time, first, check the additional service by using the home location register to confirm that the notification message service has been subscribed, and since the call forwarding setting registration has been confirmed the information of the call forwarding request terminal and the call forward target terminal.

When the message transmission instruction is received in this way, a procedure for checking the location information of the corresponding terminal (term # 1) is performed by inquiring the call forwarding request terminal (# 1 terminal) information to the home location register.

After confirming the location of the # 1 terminal, the message center performs a procedure of transmitting a call forwarding notification message to the # 1 terminal. In this case, the message is transmitted to the call forwarding request terminal (terminal # 1) by the Call_FWD_Alert parameter described above.

In addition, the message center requests the VAS to transmit the message to the # 2 terminal to transmit a notification message to the call forwarding target terminal (# 2 terminal), and receives a message from the VAS to the # 2 terminal. (9)

The message center receives a message from the VAS to the # 2 terminal, and proceeds to inquire and confirm the location information of the # 2 terminal with the home location register.

After confirming the location of the # 2 terminal, the message center proceeds to a process of transmitting a call forwarding notification message to the # 2 terminal, and transmits a call forwarding notification message to both the # 1 terminal and the # 2 terminal. That is, the call forwarding processing result information may be transmitted to the call forwarding request terminal (# 1 terminal) and the call forwarding target terminal (# 2 terminal) as a notification message, thereby preventing the abuse of the call forwarding service. 11)

5 is a diagram illustrating a signal processing flow performed at each node of a communication system according to a method of providing a call forward notification message service according to another exemplary embodiment of the present invention.

In this embodiment, the terminal # 1 makes a request to release the call forwarding service set to the terminal # 2, and accordingly, the call forwarding release notification message is transmitted to both terminals (# 1 and # 2 terminals) together with the call forwarding cancellation process. Assume and explain the situation.

In accordance with the above assumption, the terminal # 1 proceeds to request the release of the call forwarding setting of the terminal # 2. In this case, the terminal # 1 may directly request the call forwarding release from the home location register, or the terminal # 1 may request the call forwarding release request through the customer center.

When requesting the call center to cancel call forwarding, the customer center requests to release call forwarding of terminal # 2 to the home location register at the request of terminal # 1.

The home location register performs the call forwarding service release processing according to the call forwarding release request, and releases and stores the call forwarding information of the # 2 terminal in the call forwarding information.

The home location register proceeds with the procedure of checking whether the subscriber who requested the call forwarding cancellation has subscribed to the additional service after the call forwarding cancellation processing. At this time, the additional service to check is a call forwarding notification additional service (24).

As a result of confirming the additional service, if the user terminal is subscribed to the call forwarding notification additional service, a procedure for transmitting the call forwarding notification additional service processing instruction is performed to the intelligent network system. In this case, since the call forwarding service is released, the content of the additional service is changed, and thus the signal is transmitted to the intelligent network in the form of the additional service change notification message.

When the intelligent network system receives the call forwarding notification additional service processing instruction or the additional service change notification message from the home location register, the intelligent network system checks whether the call forwarding setting registration processing or the call forwarding cancellation processing is performed, and confirms that the call forwarding cancellation processing is performed. In this case, the call forwarding release processing extracts information of the call forwarding release request terminal (terminal # 1) and the call forwarding release target terminal (terminal # 2) and transmits a call forwarding notification message to each terminal to the message center (SMSC). Follow the procedures that instruct you to do so. In this case, first, a notification message transmission instruction is transmitted to the call forwarding release request terminal (terminal # 1). Here, the intelligent network system may include the information of the call forwarding release request terminal (terminal # 1) and the information of the call forwarding release target terminal (terminal # 2) to transmit a message transmission instruction. In addition, when instructing the message transmission to the message center, it is indicated through the Call_FWD_Alert parameter setting.

The message center receives a notification message transmission instruction to the call forwarding release request terminal (terminal # 1) from the intelligent network system, and performs a procedure of transmitting the notification message to the terminal # 1 according to the instruction. Of course, the message transmission indication may be received from the intelligent network system through the Call_FWD_Alert parameter setting.

When receiving the message transmission instruction, first, a procedure of inquiring and confirming the location information of the corresponding terminal (terminal # 1) to the home location register is performed based on the call forwarding release request terminal (terminal # 1).

After confirming the location of the # 1 terminal, the message center performs a procedure of transmitting a call forwarding release notification message to the # 1 terminal. At this time, the message is transmitted to the call forwarding release request terminal (terminal # 1) by the aforementioned Call_FWD_Alert parameter.

In addition, the intelligent network system next performs a procedure for instructing to transmit a notification message to the call forwarding release target terminal (# 2 terminal), and instructs the notification message transmission instruction from the intelligent network to the call forwarding release target terminal (# 2 terminal).
