Server 130 and media device 160. In particular, the media device 160 includes a multimedia resource controller (MRFC) 140 and a multimedia resource processor (MRFP) 150. Other entities in the packet service system 100 are omitted from the description to clarify the subject matter of the invention.

The additional service controller 110 is to provide an additional service to the terminal 400, and in particular, may provide a caller information providing service. When the originating terminal 401 receives a session connection request message for requesting a session connection for the call with the called terminal 402, the additional service controller 110 may disconnect the session due to circumstances of the called terminal 402. If it is impossible, the media device 160 is requested to provide the caller terminal 401 with an announcement broadcast indicating that the call is impossible. The additional service controller 160 then causes the media device 160 to collect the identification number of the originating terminal 401. In addition, the additional service controller 110 may receive the identification number collected from the media device 160 and provide it to the called terminal 402.

The additional service controller 110 may provide the caller information providing service when the called terminal 402 is subscribed to the caller information providing service. In order to confirm whether the terminating terminal 402 subscribes to the caller information providing service, the additional service controller 110 inquires the service profile of the home subscriber device 130 to confirm the service profile, or the service of the home subscriber device 130. After receiving and storing the profile, the stored service profile can be queried. In addition, the additional service controller 110 receives and stores a service profile stored in the home location register 210 of the circuit service system 200 in order to confirm whether the terminating terminal 402 subscribes to the caller information providing service. By checking the stored service profile, it is possible to check whether the subscription is made. The service profile includes a list of supplementary services subscribed to by the user, and each item of the list represents a service. Here, the service includes a basic service and an additional service. The additional service controller 110 may provide a corresponding additional service when a corresponding item is activated in the service profile. On the other hand, the additional service controller 110 may not provide the corresponding additional service when the corresponding item in the service profile is deactivated.

The session controller 120 establishes a session between each entity and the terminal 400 of the packet service system 100, and takes a role of receiving and processing a SIP message transmitted from the terminal 400. The session controller 120 delivers a SIP message to each entity in the packet service system 100 to provide a service as requested by the terminal 400 so that the session is completed. The session controller 120 may include an Interrogating (CS) -CSCF, a Service (CS) -CSCF, and a P (Proxy) -CSCF.

The session controller 120 basically supports session connection, maintenance, and release between each entity of the packet service system 100. In particular, the session controller 120 may manage session connection, maintenance, and release for a voice call according to a packet exchange method between the calling terminal 401 and the called terminal 402. To this end, the session controller 120 may relay a message exchange between each entity of the packet service system 100, and perform a necessary operation according to the relaying message. In particular, according to an embodiment of the present invention, the message may use a message according to SIP, that is, a SIP message.

The SIP message used in the embodiment of the present invention will be described below.

The INVITE message is a method for requesting a session connection between a device and a device. Here, the apparatus includes respective entities of the terminal 400 and the packet service system 100. For session connection, the INVITE message specifies the target of the session connection. Therefore, according to an embodiment of the present invention, the INVITE message is a session connection request message for requesting a session connection for a voice call between the calling terminal 401 and the called terminal 402 and a session connection for announcement of the media device 160. It may be used as a broadcast session connection request message for requesting a request.

The ACK message is a method used as a response indicating that the device receiving the specific SIP message finally confirmed the specific SIP message. Therefore, the ACK message may be used as a busy confirmation message indicating that the call is confirmed in response to the busy message (486 Busy) message indicating that the call is currently busy. In addition, the ACK message may be used as a broadcast session connection acceptance confirmation message indicating that the broadcast session connection acceptance (200 OK) message indicating confirmation of the session connection for the broadcast is confirmed. In addition, the ACK message may be used as a session connection termination confirmation message indicating that the response has been confirmed in response to the session connection termination (487 RequestTerminated) message indicating that the session connection is not completed. In addition, the ACK message is a request timeout acknowledgment message indicating that the receiving terminal 402 has not responded to the session connection request (INVITE) message for a preset time, 408 RequestTimeout message, indicating that it has been confirmed. It can be used as.

The INFO message is a method used to send and receive additional information through an already connected session. Accordingly, the INFO message may be used as a number collection request message for requesting the media device 160 to collect an identification number from the calling terminal 401. In addition, the INFO message may be used as a number collection response message for providing the collected identification number according to the number collection request (INFO) message. This number collection response message includes the identification number collected by the media device 160 from the calling terminal 401.

The BYE message is a method used to release an already connected session. Therefore, the BYE message may be used as a broadcast session disconnection message requesting the release of a session connection for broadcast.

According to SIP, MESSAGE messages are for instant messaging (IM) between devices. Accordingly, the MESSAGE message may basically include text. Therefore, the MESSAGE message may be used as a caller information providing message indicating that there is a session connection request from the calling terminal 401 when the calling terminal 401 does not make a session connection request due to the circumstances of the called terminal 402. have.

REGISTER message is basically used for registration. In particular, in order to use the packet service system 100, the terminal 400 must register with the packet service system 100, and a REGISTER message for this includes information necessary for registration. Therefore, the REGISTER message may be used as a registration request message for the destination terminal 402 to request registration with the packet service system 100. In addition, the REGISTER message may be used as a registration notification message for notifying that the destination terminal 402 is registered in the packet service system 100 to the additional service controller 110.

The 1xx series message (where xx is a natural number) of the SIP messages is a kind of response message. 1xx series messages are used to indicate that a specific request message has been received and that message processing is continuing. The additional service controller 110 transmits a 183 SessionProgress message to the calling terminal 401 because it is necessary to continue the session connection procedure in order to provide the announcement to the calling terminal 401. This 183 SessionProgress message indicates that the session establishment procedure is still in progress. The additional service controller 110 may continue the session connection procedure for the announcement by sending the 183 SessionProgress message, instead of the session connection for the voice call. Accordingly, the 183 SessionProgress message may be used as a session progress message to inform that the session is in progress.

Among the SIP messages, 2xx series messages (where xx is a natural number) are used to inform success in response to a specific SIP message. In particular, a 200 OK message is used to indicate acceptance, acknowledgment, acknowledgment, and the like for a particular message. Accordingly, according to an embodiment of the present invention, the 200 OK message may be used as a broadcast session connection acceptance message meaning to accept a session connection in response to a broadcast session connection request (INVITE) message. In addition, the 200 OK message may be used as a number collection acceptance message that accepts to collect the identification number from the originating terminal 401 in response to the number collection request (INFO) message. The 200 OK message may be used as a number collection confirmation message for notifying that the ID number transmitted by the media device 160 has been received and stored in response to the number collection response (INFO) message. Also, the 200 OK message may be used as a broadcast session disconnection acceptance message indicating that the 200OK message is accepted in response to the broadcast session disconnection (BYE) message. In addition, the 200 OK message may be used as a registration acceptance message indicating that the destination terminal 402 receives a registration request (REGISTER) message requesting registration to the packet service system 100. In addition, the 200 OK message may be used as a registration confirmation message indicating that the called terminal 402 has been registered in response to a REGISTER message indicating that the destination terminal 402 has been registered in the packet service system 100.

Among the SIP messages, 4xx series messages (where xx is a natural number) are used as a response message to notify a failure in response to a specific SIP message. That is, the 4xx series message indicates that an error is included in a specific SIP message or that a specific SIP message cannot be processed in response to a specific SIP message.

486 Busy message indicates that a particular SIP message cannot be processed because it is busy. Accordingly, the 486 busy message may be used as a busy notification message indicating that the session connection request cannot be processed because the busy terminal is in response to the session connection request (INVITE) message transmitted by the calling terminal 401.

487 The RequestTerminated message indicates that the request has ended in response to a specific request message. Accordingly, the 487 RequestTerminated message may be used as a session connection termination message indicating that the session connection request has ended. The additional service controller 110 responds to the session connection request (INVITE) message requesting a session connection with the called terminal 402 of the calling terminal 401 instead of the called terminal 402 and sends a 487 RequestTerminated message. Can be sent to.

The 408 RequestTimeout message is used to indicate that there is no response when there is no response for a specific SIP message. Accordingly, the 408 RequestTimeout message is a request time for notifying the additional service controller 110 that, when the called terminal 402 does not respond to the session connection request (INVITE) message for a preset time, it cannot respond within the preset time. Can be used as an expiration message.

The home subscriber device 130 stores user information and supports entities performing session control. The home subscriber device 130 stores user subscription information related to session control, that is, location information of the user, security information for authentication and permission of the user, and a service profile that is a list of services subscribed to by the user.

When providing the caller information providing service, the media device 160 may connect a session between the media device 160 itself and the calling terminal 401 at the request of the additional service controller 110. This session is a session for announcement and a session for collecting identification numbers of the calling terminal 401. When such a session is connected, the media device 160 provides the announcement broadcast to the calling terminal 401 at the request of the supplementary service controller 110. This announcement broadcasts that the session connection with the called terminal 402 is impossible, and includes a request for a number for contacting the called terminal 402, that is, an identification number of the calling terminal 401. According to the announcement, when the calling terminal 401 inputs the identification number, the media device 160 receives the identification number through the connected session and stores the identification number. For example, the format of the identification number transmitted by the calling terminal 401 through the connected session may be a dual tone multiple frequency (DTMF) signal. Then, the media device 160 may recognize the identification number received in the DTMF signal in the number format. To this end, the media device 160 may include a DTMF decoder which decodes the DTMF signal, converts the number into a digital format, and outputs the digital number. The media device 160 may collect the identification number of the calling terminal 401 according to the above-described method, and provide the collected identification number to the additional service controller 110.

The media device 160 includes a multimedia resource controller 140 and a multimedia resource processor 150. When the session is connected, the multimedia resource controller 140 may control the multimedia resource processor 150 to transmit an announcement broadcast and collect an identification number. The multimedia resource processor 150 may provide an announcement broadcast to the calling terminal 401 under the control of the multimedia resource controller 140 and may collect an identification number. The above-described multimedia resource controller 140 and the multimedia resource processor 150 may be implemented as independent equipment or one equipment.

Next, the configuration of the circuit service system 200 according to an embodiment of the present invention will be described. The circuit service system 200 includes a home location register (HLR) 210 and an intranet gateway (IGW) 220.

The home location register 210 basically manages a user in the circuit service system 200. That is, the home location register 210 may perform functions such as user authentication and location registration. In particular, the home location register 210 may manage a service subscribed to by the user. This service includes basic service and additional service. Here, the basic service may illustrate a voice call, and the additional service may illustrate a call forwarding, a voice message, a caller information providing service, and the like. In order to manage a service subscribed to by the user, the home location register 210 may store a service profile that is a list of services subscribed to by the user. Each item in this list represents a service, and if the item is activated, the service can be provided. If the item is deactivated, the service cannot be provided. The above services include basic services and additional services.

The intranet gateway 220 is a gateway between the value added controller 110 and the home location register 210. That is, the intranet gateway 220 connects the additional service controller 110 and the home location register 210.

4 and 5 are flowcharts illustrating a method for providing caller information of a packet service system according to a first embodiment of the present invention.

4 and 5, the originating terminal 401 transmits a session connection request message to the session controller 120 in step S401. The session connection request message is for the originating terminal 401 to request a session connection for a call with the called terminal 402. The session connection request message may use an INVITE message according to the SIP. The session connection request (INVITE) message is transmitted to the called terminal 402 via the session controller 120, the additional service controller 110, and the session controller 120 in steps S403 to S407.

The terminating terminal 402 is assumed to be busy when it receives a session connection request (INVITE) message. Then, the called terminal 402 transmits the busy notification message to the session controller 120 in step S409. The busy notification message informs that the state of the called terminal 402 is busy. The busy notification message may use a 486 Busy message, according to the SIP. The session controller 120 transmits a busy notification (486 Busy) message to the additional service controller 110 in step S411.

The additional service controller 110 receiving the busy notification message 486 may check that the called terminal 402 is busy. Accordingly, the additional service controller 110 transmits a busy confirmation message to the session controller 120 in step S413. The busy confirmation message is a message indicating that the confirmation is in response to the busy message (486 Busy) message. This busy confirmation message may use an ACK message according to the SIP. The session controller 120 transmits this busy acknowledgment (ACK) message to the called terminal 402 in step S415.

The additional service controller 110 confirms that the called terminal 402 is busy, and operates the caller information providing service in step S417. Accordingly, the additional service controller 110 starts a process of interworking with the media device 160 in step S419. That is, in step S421, the additional service controller 110 transmits a broadcast session connection request message to the session controller 120 requesting a session connection between the media device 160 and the originating terminal 401. The broadcast session connection request message is for requesting to connect a session between the media device 160 and the calling terminal 401. Here, the broadcast session connection request message may use an INVITE message according to SIP. In operation S423, the session controller 120 transmits a broadcast session connection request (INVITE) message to the media device 160.

When the media device 160 receives the broadcast session connection request (INVITE) message, the media device 160 transmits the broadcast session connection acceptance message to the session controller 120 in step S425. Here, the broadcast session connection acceptance message has a meaning of accepting a session connection with the calling terminal 401. The broadcast session connection accept message may use a 200 OK message, according to SIP. The session controller 120 transmits this 200 OK message to the additional service controller 110 in step S427.

When receiving the broadcast session connection acceptance 200 OK message, the additional service controller 110 transmits the session progress message to the session controller 120 in step S429. The session progress message is a response to a session connection request (INVITE) message sent by the originating terminal 401 and is intended to inform that the session establishment is still in progress and is transmitted to the originating terminal 401. This session progress message may use a 183 SessionProgress message, according to the SIP. Subsequently, the session controller 120 transmits a session progress message 183 SessionProgress to the originating terminal 401 in step S431.

For the caller information providing service, an announcement broadcast may be provided to the calling terminal 401. In order to provide the announcement, the session establishment procedure must be ongoing. Therefore, the additional service controller 110 transmits a session progress message 183 SessionProgress in response to the session connection request (INVITE) message instead of the destination terminal 402. The originating terminal 401 may proceed with other procedures, such as retrying the session connection request when the session request is rejected, suspended or terminated. However, the originating terminal 401 may not proceed with the other procedures described above by receiving a session progress message (183 SessionProgress).

After transmitting the session progress message (183 SessionProgress), the additional service controller 110 transmits a broadcast session connection acceptance confirmation message to the session controller 120 in step S433. The broadcast session connection acceptance confirmation message is a broadcast session connection acceptance confirmation message indicating that the confirmation of acceptance of the session connection for broadcasting. The broadcast session connection acceptance confirmation message may use an ACK message according to the SIP. The session controller 120 transmits a broadcast session connection acceptance acknowledgment (ACK) message to the media device 160 in step S435. As a result, a session for broadcast and identification number collection is connected between the calling terminal 401 and the media device 160.

When a session is connected between the calling terminal 401 and the media device 160, the additional service controller 110 starts a process for collecting identification numbers of the calling terminal 401 in step S437.

That is, the additional service controller 110 transmits a number collection request message to the session controller 120 in step S439. The number collection request message is for requesting the media device 160 to collect an identification number from the calling terminal 401. This number collection request message may use an INFO message according to the SIP. The session controller 120 transmits the number collection request message to the media device 160 in step S441.

In response to the number collection request message, the media device 160 transmits a number collection acceptance message to the session controller 120 in step S443. The number collection accept message is to accept the collection of the identification number from the calling terminal 401. The number collection accept message may use a 200 OK message according to SIP. In step S445, the session controller 120 transmits the number collection accept message (200 OK) to the additional service controller 110.

According to the number collection request message, the media device 160 may collect the identification number of the calling terminal 401 in step S447. In more detail, the media device 160 may provide a guide broadcast for guiding that a current call cannot be made due to the circumstances of the called terminal 402 through a connected session. In addition, when the user of the calling terminal 401 inputs the identification number, the media device 160 provides a guide broadcast to inform the recipient terminal 402 that the input identification number will be transmitted. Induce the identification number entry. In this case, it is assumed that the user of the calling terminal 401 inputs the identification number, and the calling terminal 401 transmits the identification number input by the user through the connected session. Then, the media device 160 receives the identification number sent by the calling terminal 401 and stores the received identification number. In this case, the identification number transmitted from the calling terminal 401 may be a DTMF signal, and the media device 160 may recognize and store the DTMF signal as a number.

When the identification number is collected according to the above-described method, the media device 160 includes the identification number collected in the number collection response message, and then, in step S449, the number collection response message including the identification number to the session controller 120. send. The number collection response message is a message for providing the collected identification number in response to the number collection request (INFO) message. This number collection response message may use an INFO message, according to the SIP. Subsequently, the session controller 120 transmits a number collection response (INFO) message to the additional service controller 110 in step S451. The additional service controller 110 receiving the number collection response message stores the identification number of the originating terminal 401 included in the number collection response message in step S453.

After storing the identification number, the additional service controller 110 transmits the number collection confirmation message to the session controller 120 in step S455. The number collection confirmation message informs that the identification number sent by the media device 160 has been received and stored. This number collection confirmation message may use a 200 OK message, according to SIP. The session controller 120 transmits a number collection confirmation (200 OK) message to the media device 160 in step S457.

After transmitting the number collection confirmation 200 OK message, the additional service controller 110 transmits a broadcast session connection release message to the session controller 120 in step S459. The broadcast session disconnect message is for disconnecting a session between the media device 160 and the calling terminal 401. The broadcast session disconnect message may use a BYE message according to SIP. The session controller 120 transmits a broadcast session disconnection (BYE) message to the media device 160 in step S461.

The media device 160 receiving the broadcast session disconnection (BYE) message transmits a broadcast session disconnection accept message to the session controller 120 in step S463. The broadcast session disconnection accept message is to accept the release of the broadcast session connection between the calling terminal 401 and the media device 160 in response to the broadcast session disconnection message. The broadcast session disconnection accept message may use a 200 OK message according to the SIP. Subsequently, the session controller 120 transmits a broadcast session disconnection acceptance (200 OK) message to the additional service controller 110 in step S465. Accordingly, the session connection between the media device 160 and the calling terminal 401 is released.

After receiving the broadcast session disconnection acceptance 200 OK message, the additional service controller 110 transmits a session connection termination message to the session controller 120 in step S467. This session connection termination message is a response to the session connection request (INVITE) message sent by the originating terminal 401 to the first (step S401), and informs that the session connection request has ended. The session connection termination message may use a 487 RequestTerminated message according to the SIP. That is, the originating terminal 401 transmits a session connection request (INVITE) message in step S401, but the session connection termination (487 RequestTerminated) message informs that the request through the session connection request (INVITE) message is terminated. Subsequently, the session controller 120 transmits a session connection termination (487 RequestTerminated) message to the calling terminal 401 in step S469.

The originating terminal 401 receiving the session connection termination (487 RequestTerminated) message transmits a session connection termination confirmation message to the session controller 120 in step S471. The session connection termination confirmation message responds to the session connection termination (487 RequestTerminated) message to indicate that it has been confirmed. This session connection termination confirmation message may be used according to the SIP, ACK message. The originating terminal 401 transmits a session connection end acknowledgment (ACK) message and then terminates the process. Subsequently, the session controller 120 transmits a session connection termination confirmation (ACK) message to the additional service controller 110 in step S473.

The additional service controller 110 transmits a caller information providing message to the called terminal 402 in step S475. The caller information providing message includes an identification number of the calling terminal 401 stored in step S453. The caller information providing message is for notifying that the called terminal 402 has a call connection request to the called terminal 402 when the called terminal 402 cannot make a call. For example, the caller information providing message may include "[Please contact] Mon / Day / 00: 00:01 01-234-5678 and you will be automatically connected by pressing the call button." Here, “011-234-5678” is an identification number collected by the media device 160 from the calling terminal 401. Therefore, the receiving terminal 402 receiving the caller information providing message may display the above contents on the screen. Accordingly, the user of the called terminal 402 can know that the call request from the calling terminal 401. In addition, according to the selection of the user of the called terminal 402, the call terminal 401 may request a call connection. The caller information providing message may use a MESSAGE message or a Short Messaging Service (SMS) message according to SIP.

6 and 7 are flowcharts illustrating a method for providing caller information in a packet service system according to a second embodiment of the present invention.

6 and 7, the originating terminal 401 transmits a session connection request message INVITE to the session controller 120 in step S601. The session connection request (INVITE) message is transmitted to the called terminal 402 through the session controller 120, the additional service controller 110, and the session controller 120 in steps S603 to S607. The session connection request message is for the originating terminal 401 to request a session connection for a call with the called terminal 402.

The session controller 120 transmits a session connection request message to the called terminal 402 in step S607 and waits for a response from the called terminal 402 for a preset time. In this case, it is assumed that there is no response of the called terminal 402 for a preset time. As such, if there is no response from the called terminal 402 for the preset time, the session controller 120 transmits the request timeout message to the additional service controller 110 in step S609. The request timeout message is a message indicating that there is no response from the called terminal 402 within a preset time. This request timeout message may use a 408 RequestTimeout message, according to the SIP.

Upon receiving the request timeout message 408 RequestTimeout, the additional service controller 110 transmits a request timeout confirmation message to the session controller 120 in step S611. The request timeout confirmation message informs that the called terminal 402 has confirmed that there is no response within the preset time according to the request timeout message (408 RequestTimeout). This request timeout confirmation message may use an ACK message, according to the SIP.

The additional service controller 110 determines that the session connection with the destination terminal 402 is impossible when the request timeout message 408 is received. In addition, the additional service controller 110 transmits the request time expiration confirmation (ACK) message, and then, in step S613, operates the caller information providing service.

When the caller information providing service is driven, the packet service system 100 connects a session between the calling terminal 401 and the media device 160 through the procedures of steps S615 to S631. Then, the packet service system 100 provides a guide broadcast to the calling terminal 401 through the connected session in steps S633 to S661, and proceeds to collect the identification number of the calling terminal 401. Then, the packet service system 100 terminates the session connection request of the originating terminal 401 through the steps S663 to S669. In operation S671, the packet service system 100 transmits a caller information providing message including an identification number of the calling terminal 401 to the called terminal 402 through the additional service controller 110. As described above, the packet service system 100 may provide a caller information providing service in steps S613 to S671. Since the steps S613 to S671 are the same as the steps S417 to S475 in the first embodiment with reference to FIGS. 4 and 5, detailed description thereof will be omitted.

8 and 9 are flowcharts illustrating a method for providing caller information of a packet service system according to a third embodiment of the present invention.

8 and 9, the originating terminal 401 transmits a session connection request message INVITE to the session controller 120 in step S801. Subsequently, the session controller 120 transmits a session connection request (INVITE) message to the additional service controller 110 in step S803. The session connection request message is for the originating terminal 401 to request a session connection for a call with the called terminal 402.

The additional service controller 110 may check whether the destination terminal 402, which is the target of the session connection request (INVITE) message, is registered at step S805. In this case, it is assumed that the called terminal 402 is not registered. Then, since the terminating terminal 402 is not registered, the additional service controller 110 determines that the session connection cannot be made to the terminating terminal 402, and drives the caller information providing service in step S807.

When the caller information providing service is driven, the packet service system 100 connects a session between the calling terminal 401 and the media device 160 through the procedure of step S809 to step S825. Then, the packet service system 100 provides the announcement broadcast to the calling terminal 401 through the session connected in step S827 to step S855, and proceeds to collect the identification number of the calling terminal 401. In particular, in step S843, the additional service controller 110 may store an identification number of the calling terminal 401 received from the media device 160. Then, the packet service system 100 terminates the session connection request of the originating terminal 401 through step S857 and S863. Steps S807 to S863 described above are the same as steps S417 to S473 of the first embodiment and steps S613 to S669 of the second embodiment, and thus a detailed description thereof will be omitted.

As such, the additional service controller 110 stores the identification number of the calling terminal 401. In this case, it is assumed that the called terminal 402 is powered on in step S865. When the power is turned on, the called terminal 402 transmits a registration request message to the session controller 120 in step S867. The registration request message is a message for the destination terminal 402 to request registration with the packet service system 100. Such a registration request message may use a REGISTER message according to SIP.

After receiving the REGISTER message, the session controller 120 proceeds with the registration procedure. That is, the session controller 120 queries the home subscriber device 130 and requests authentication of the called terminal 402. Accordingly, the registration is completed when the home subscriber device 130 is authenticated. As such, when the registration of the called terminal 402 is completed, the session controller 120 transmits a registration accept message to the called terminal 402 in step S869. The registration acceptance message informs that the registration of the called terminal 402 is accepted. The registration acceptance message preferably uses a 200 OK message according to the SIP.

Then, the session controller 120 transmits a registration notification message to the additional service controller 110 in step S871. The registration notification message is for notifying that the called terminal 402 is registered in the packet service system 100. The registration notification message may use the REGISTER message according to the SIP.

When receiving the registration notification (REGISTER) message, the additional service controller 110 transmits a registration confirmation message to the session controller 120 in step S873 in response to the registration notification message (REGISTER). The registration confirmation message informs that the registration of the called terminal 402 is confirmed in response to the registration notification (REGISTER) message. This registration confirmation message may use a 200 OK message, according to the SIP.

The additional service controller 110 may confirm that the called terminal 402 is powered on through a registration notification (REGISTER) message. Accordingly, the additional service controller 110 confirms the registration of the called terminal 402 in step S875, and transmits a caller information provision (MESSAGE or SMS) message to the called terminal 402 in step S877. The sender information provision (MESSAGE or SMS) message includes the identification number of the calling terminal 401 stored in step S843.

10 is a flowchart illustrating a method for providing caller information of an additional service controller according to an embodiment of the present invention.

The additional service controller 110 may receive a session connection request (INVITE) message that the originating terminal 401 requests a session connection to the called terminal 402 in step S1001. Then, the additional service controller 110 checks whether the destination terminal 402, which is the target of the session connection request (INVITE) message, is subscribed to the caller information providing service in step S1003. The subscription of the caller information providing service can be confirmed through the service profile.

As a result of checking in step S1003, if the called terminal 402 is not subscribed to the caller information providing service, the additional service controller 110 proceeds to step S1005 to perform a process according to the general procedure. On the contrary, if the called terminal 402 is subscribed to the caller information providing service, the additional service controller 110 proceeds to step S1007.

The additional service controller 110 determines whether the session connection to the called terminal 402 is impossible in step S1007. That is, the additional service controller 110 determines whether or not session connection with the called terminal 402 can be made according to the session connection request of the calling terminal 401. When the called terminal 402 is busy, when the called terminal 402 cannot talk, and when the called terminal 402 is not registered, the additional service controller 110 may establish a session connection with the called terminal 402. I cannot judge it. In more detail, in step S1007, when the additional service controller 110 receives the busy notification message (486 Busy), it determines that the called terminal 402 is busy. In addition, when the additional service controller 110 receives the request timeout message 408 RequestTimeout from the session controller 120, the additional service controller 110 determines that the called terminal 402 cannot talk. The additional service controller 110 determines that the called terminal 402 is not registered when the called terminal 402 is not registered in the packet service system 100.

Accordingly, the additional service controller 110 proceeds to step S1009 when the session connection with the destination terminal 402 is impossible in step S1007, and proceeds to step S1005 when the destination terminal 402 is capable of session connection. Follow the normal procedure.

The additional service controller 110 collects an identification number of the calling terminal 401 in cooperation with the media device 160 in step S1009. That is, the additional service controller 110 collects the identification number of the calling terminal 401 through the media device 160. The media device 160 connects the session with the originating terminal 401 at the request of the supplementary service controller 110. Then, the media device 160 provides the announcement broadcast to the calling terminal 401, and may collect the identification number of the calling terminal 401 from the calling terminal 401 according to the announcement broadcast. In addition, the media device 160 transmits the collected identification number to the additional service controller 110. Accordingly, the additional service controller 110 may receive and store the identification number of the calling terminal 401.

Next, the additional service controller 110 transmits a caller information providing message to the called terminal 402 in step S1011, and when the called terminal 402 cannot connect to the session, there was a call connection request from the calling terminal 401.
