In addition, the origination information providing server 111 may be combined with the service subscriber database 113 and the web server 115.

Here, the home location register 101 may manage the location information of the mobile terminal to transfer the call of the calling terminal to the called terminal. In addition, the home location register 101 may transmit the unreachable information to the calling information providing server 111 when the called terminal does not answer or cannot answer the call of the calling terminal in a call waiting state. Meanwhile, the home location register 101 may store information on whether a user subscribes to an additional service (eg, a catch call) corresponding to the mobile terminal.

In addition, the originating information providing server 111 may receive the call forwarding information from the home location register 101 and transmit a message transmission request corresponding to the call forwarding information to the short message service center 103. .

In addition, the short message service center 103 transmits to the called terminal when the called terminal can receive a message in response to a message transmission request corresponding to the unreachable information transmitted from the originating information providing server 111. Informational messages can be sent. On the other hand, the originating information providing system for the caller-based incoming call can not include a multimedia message service center (not shown). Here, the outgoing information message may include an image, a video, etc. through the multimedia message service center.

Referring to the above configuration, a brief description of a method for providing outgoing information for a caller-based incoming call is not possible according to the present invention.

First, a user corresponding to an originating terminal may subscribe to an originating information providing service for a caller based incoming call impossible according to the present invention through the Internet. In this case, a user corresponding to the calling terminal may designate a caller identification message and a caller identification icon.

Even if there is an outgoing call from the calling terminal, when the called terminal does not answer or cannot answer the call of the calling terminal while waiting for a call, the user corresponding to the calling terminal cannot call the user corresponding to the called terminal. In this case, the home location register 101 may collect unreachable information corresponding to any one of cases where the called terminal does not answer or cannot answer the call of the calling terminal in a call waiting state through a mobile communication network. have. Thereafter, the home location register 101 may transmit the unreachable information to the originating information providing server 111.

Accordingly, the origination information providing server 111 may transmit a message transmission request corresponding to the unreachable information to the short message service center 103. Here, the message transmission request may be generated based on service subscriber information prepared in advance by a user corresponding to the calling terminal.

Thereafter, the short message service center 103 may transmit the called terminal location request signal to the home location register 101. Accordingly, the home location register 101 may transmit the destination terminal location information to the short message service center 103. Thereafter, the short message service center 103 may transmit an outgoing information message corresponding to the unreachable information to the called terminal through the called side exchange 107 based on the called terminal location information.

Accordingly, the called terminal may receive and output the originating information message transmitted from the called side exchange 107. Here, the caller information message may include a caller terminal number, caller ID, caller identification message, caller identification icon, and the like.

2 is a flowchart schematically illustrating a process of providing outgoing information on a caller-based call forwarding call to a call waiting state according to a preferred embodiment of the present invention.

Referring to FIG. 2, a user corresponding to an originating terminal may subscribe to an outgoing call information providing service for a caller based call impossible call according to the present invention through the Internet. In this case, a user corresponding to the calling terminal may designate a caller identification message and a caller identification icon. Thereafter, the user may attempt to make a call connection through a mobile communication network to a specific destination terminal using the calling terminal (step 201). Even if there is a call from the calling terminal, when the called terminal subscribed to the call waiting service does not answer or cannot answer the call of the calling terminal during call waiting, the user corresponding to the calling terminal is connected with the user corresponding to the called terminal. The call cannot be made (step 203). In this case, one of a call call service, a calling number display service, a message blocking service, or an outgoing call information providing service for an impossible caller may be provided according to whether the called terminal has an additional service subscription (step 205).

If it is determined that the called terminal is subscribed to the catch call service, the catch call service is provided when the called terminal subscribed to the call waiting service does not answer or cannot answer the call of the calling terminal during call waiting. (Step 207). If it is determined that the called terminal is subscribed to the calling number display service, the calling number display service is not available when the called terminal subscribed to the call waiting service does not answer or cannot answer the call of the calling terminal during call waiting. Is provided (step 209). If it is determined that the called terminal is subscribed to the message blocking service, the message blocking service is provided even if the called terminal subscribed to the call waiting service does not answer or cannot answer the call of the calling terminal during call waiting. In step 211, the calling information providing service for the caller-based unreachable call is not provided. The message blocking service according to a preferred embodiment of the present invention means a service provided by a called terminal that blocks reception of outgoing information on the caller-based incoming call impossible. If the called terminal is not subscribed to any one of the catch call service, the calling number display service, and the message blocking service, it is determined that the called terminal is subscribed to the calling information providing service for the caller based unreachable call according to the present invention. When the called terminal subscribed to the call waiting service does not answer or cannot answer the call of the calling terminal during the call waiting, the calling information providing service for the caller based unreachable call is provided (213).

Signal flow diagram schematically illustrating the process.

Referring to FIG. 3, in response to an origination of an originating terminal, the originating exchange may transmit a routing information request to a home location register (step 301). In response to the routing information request, the home location register T_HLR may send a call routing information request to the destination exchange T_MSC / VLR (step 303). At this time, if it is determined that the called terminal is busy (step 305), according to the call waiting service, the called side exchange T_MSC / VLR may transmit call routing information to the home location register T_HLR (step 307).

In response to the call routing information, the home location register T_HLR may send routing information to the originating side switch O_MSC / VLR (step 309). In response to the routing information, the originating exchange O_MSC / VLR may transmit a call connection request for a call between the originating terminal and the called terminal to the called side exchange T_MSC / VLR (step 311). .

In this case, the called side exchange T_MSC / VLR may collect information from the called terminal that there is no response (step 313). Accordingly, the called side exchange T_MSC / VLR may transmit the non-receipt information corresponding to the called terminal non-response information to the calling side exchange O_MSC / VLR (step 315). Accordingly, the originating exchange O_MSC / VLR may transmit the non-receipt information to the home location register T_HLR (step 317). Thereafter, the home location register T_HLR may transmit the unreachable information to the originating information providing server (step 319).

The originating information providing server may transmit a message transmission request corresponding to the undeliverable information to the short message service center (SMSC) (step 321). The short message service center SMSC may transmit an incoming terminal location request to the home location register T_HLR (step 323). Accordingly, the home location register T_HLR may transmit the destination terminal location information to the short message service center SMSC (step 325). Thereafter, the short message service center SMSC may transmit an originating information message corresponding to the unreachable information to the called side exchange T_MSC / VLR with reference to the called terminal location information (step 327).

FIG. 4 is a signal flowchart schematically illustrating a process of processing a message when a catch call service and an originating information providing service for a caller based non-call impossible according to an exemplary embodiment of the present invention are superimposed.

Referring to FIG. 4, in response to an origination of the originating terminal, the originating exchange O_MSC / VLR may transmit a routing information request to the home location register T_HLR (step 401). In response to the routing information request, the home location register T_HLR may send a call routing information request to the destination exchange T_MSC / VLR (step 403). In this case, when it is determined that the called terminal is busy (step 405), the called side exchange T_MSC / VLR may transmit call routing information to the home location register T_HLR according to the call waiting service (step 407).

In response to the call routing information, the home location register T_HLR may send routing information to the originating exchange O_MSC / VLR (step 409). In response to the routing information, the originating exchange (O_MSC / VLR) may transmit a call connection request for a call between the originating terminal and the called terminal to the called side exchange (T_MSC / VLR) (step 411). .

In this case, the called side exchange T_MSC / VLR may collect information from the called terminal that there is no response (step 413). Accordingly, the called side exchange T_MSC / VLR may transmit the non-receipt information corresponding to the called terminal non-response information to the calling side exchange O_MSC / VLR (step 415). Accordingly, the originating exchange O_MSC / VLR may transmit the unreachable information to the home location register T_HLR (step 417).

 In response to the undeliverable information, the home location register T_HLR may determine whether the user corresponding to the called terminal is a catch call service subscriber (step 419). Here, whether or not the catch call service subscriber is determined may be determined based on catch call service subscriber information prepared in advance by a user corresponding to the called terminal. As a result of the determination, when the user corresponding to the called terminal is not a catch call service subscriber, the home location register T_HLR may transmit the impossible call information to the originating information providing server. Thereafter, the originating information providing server may transmit an originating information message to the called terminal when the called terminal is in a state capable of receiving a message in association with a short message service center (SMSC). That is, the home location register T_HLR may provide the calling information providing service for the caller based unreachable call according to the present invention in association with the calling information providing server and the short message service center (SMSC) (step 421).

If it is determined in step 419 that the user corresponding to the called terminal is a catch-call service subscriber, the home location register (T_HLR) provides call forwarding information so that a duplicate message regarding outgoing information is not transmitted to the called terminal. The originating information providing service for the caller based unreachable call may be terminated without transmitting to the server (step 423).

FIG. 5 is a signal flowchart schematically illustrating a process of processing a message when a caller ID display service and a caller ID providing service for a caller-based call forwarding call are overlapped according to an embodiment of the present invention.

Referring to FIG. 5, in response to an origination of an originating terminal, the originating exchange O_MSC / VLR may transmit a routing information request to the home location register T_HLR (step 501). In response to the routing information request, the home location register T_HLR may send a call routing information request to the called side exchange T_MSC / VLR (step 503). At this time, if it is determined that the called terminal is busy (step 505), according to the call waiting service, the called side exchange T_MSC / VLR may transmit call routing information to the home location register T_HLR (step 507).

In response to the call routing information, the home location register T_HLR may send routing information to the originating exchange O_MSC / VLR (step 509). In response to the routing information, the originating exchange (O_MSC / VLR) may transmit a call connection request for a call between the originating terminal and the called terminal to the called side exchange (T_MSC / VLR) (step 511). .

In this case, the called side switch (T_MSC / VLR) may collect information that there is no response from the called terminal (step 513). Accordingly, the called side exchange T_MSC / VLR may transmit the non-receipt information corresponding to the called terminal non-response information to the calling side exchange O_MSC / VLR (step 515). Accordingly, the originating exchange O_MSC / VLR may transmit the non-receipt information to the home location register T_HLR (step 517).

 In response to the undeliverable information, the home location register T_HLR may determine whether the user corresponding to the called terminal is a calling party number indicating service subscriber (step 519). Here, whether the caller ID service subscriber is determined may be determined based on caller ID service subscriber information prepared in advance by a user corresponding to the called terminal. As a result of the determination, when the user corresponding to the called terminal is not the calling party number display service subscriber, the home location register T_HLR may transmit the call impossible information to the calling information providing server. Thereafter, the originating information providing server may transmit an originating information message to the called terminal when the called terminal is in a state capable of receiving a message in association with a short message service center (SMSC). That is, the home location register T_HLR may provide outgoing information provision service for outgoing caller based incoming call according to the present invention in association with the outgoing information provision server and the short message service center SMSC (step 521).

If it is determined in step 519 that the user corresponding to the called terminal is a calling party number indication service subscriber, the home location register (T_HLR) transmits unreachable information so that a duplicate message about calling information is not transmitted to the called terminal. The calling information providing service for the caller based unreachable call may be terminated without transmitting to the providing server (step 523).

FIG. 6 is a signal flowchart schematically illustrating a process of processing a message when a message blocking service and an originating information providing service for a caller-based incoming call cannot be applied according to an exemplary embodiment of the present invention.

Referring to FIG. 6, in response to an origination of an originating terminal, the originating exchange O_MSC / VLR may transmit a routing information request to the home location register T_HLR (step 601). In response to the routing information request, the home location register T_HLR may send a call routing information request to the destination side exchange T_MSC / VLR (step 603). At this time, if it is determined that the called terminal is busy (step 605), according to the call waiting service, the called side exchange T_MSC / VLR may transmit call routing information to the home location register T_HLR (step 607).

In response to the call routing information, the home location register T_HLR may send routing information to the originating exchange O_MSC / VLR (step 609). In response to the routing information, the originating exchange O_MSC / VLR may transmit a call connection request for a call between the originating terminal and the called terminal to the called side exchange T_MSC / VLR (step 611). .

In this case, the called side exchange T_MSC / VLR may collect information from the called terminal that there is no response (step 613). Accordingly, the called side exchange T_MSC / VLR may transmit the non-receipt information corresponding to the called terminal non-response information to the calling side exchange O_MSC / VLR (step 615). Accordingly, the originating exchange O_MSC / VLR may transmit the non-receipt information to the home location register T_HLR (step 617).

 In response to the undeliverable information, the home location register T_HLR may determine whether the user corresponding to the called terminal is the calling party number indicating service subscriber (step 619). Here, whether or not the message blocking service subscriber is determined may be determined based on message blocking service subscriber information prepared in advance by a user corresponding to the called terminal. As a result of the determination, when the user corresponding to the called terminal is not a message blocking service subscriber, the home location register T_HLR may transmit the impossible call information to the originating information providing server. Thereafter, the originating information providing server may transmit an originating information message to the called terminal when the called terminal is in a state capable of receiving a message in association with a short message service center (SMSC). That is, the home location register T_HLR may provide outgoing information provision service for an outgoing caller based incoming call according to the present invention in association with the outgoing information provision server and the short message service center SMSC (step 621).

If it is determined in step 619 that the user corresponding to the called terminal is a message blocking service subscriber, the home location register (T_HLR) transmits unreachable information so that a message regarding outgoing information is not transmitted to the called terminal. The calling information providing service for the caller based unreachable call may be terminated without transmitting to the call (step 623).
