The access service system 300 provides a wireless section service to the terminal 400 and the terminal 400 can access the packet service system 100 or the circuit service system 200 through the access service system 300.

In the embodiment of the present invention, a terminal 400 requesting a call connection among terminals 400 is referred to as an originating terminal 401 and a terminal 400 to be a call connection terminal is referred to as a terminating terminal 402. [ In addition, in an embodiment of the present invention, when the calling terminal 401 requests a call, the called terminal 402 may be in a call, and the third terminal may call any terminal 400 talking to the called terminal 402. The terminal 403 will be referred to as. The terminal 400 has an identification number, and the identification number is information for distinguishing the terminal from other terminals 400. For example, the identification number may be a telephone number.

The packet service system 100 can basically provide a voice call service to the terminal 400. [ The packet service system 100 can allocate resources for communication between the calling terminal 401 and the called terminal 402 when the calling terminal 401 requests a call connection with the called terminal 402. According to the Session Initiation Protocol (SIP), resource allocation is performed through session connection between the calling terminal 401 and the called terminal 402. When the session is connected, the calling terminal 401 and the called terminal 402 can exchange voice packets through a connected session, which can be performed according to the mVoIP (mobile voice over IP) method.

In addition, the packet service system 100 may provide an additional service for a voice call service, which is a basic service. In particular, the packet service system 100 may provide a caller information providing service as an additional service. The caller information providing service is an additional service provided to the called terminal 402. The caller information providing service, if the calling terminal 401 has requested a session connection to the called terminal 402 for a call, but due to the circumstances of the called terminal 402, the session connection is impossible, the identification number of the calling terminal 401 Is an additional service that collects and provides the called terminal 402.

The terminal 400 can access the packet service system 100 through an access network 300 and the terminal 400 can access the packet service system 100 through the terminal 400. [ And connects the terminal 400 and the packet service system 100 to each other. The packet service system 100 may support all sorts of the access service system 300. For example, the access service system 300 may be a fixed access system such as a digital subscriber line (DSL), a cable modem, and an Ethernet. In this case, the access service system 300 connects the terminal 400 to the packet service system 100 through a modem, a router, a gateway, A wired connection service may be provided. Also, the access service system 300 may be a mobile access system such as W-CDMA, CDMA2000, GSM, and GPRS. In this method, the access service system 300 includes a base station, a base station controller, a gateway, and the like, and provides a wireless section service between the access service system 300 and the terminal 400, The service system 100 can be connected. The access service system 300 may be a wireless access network such as a WLAN (Wireless Local Area Network), a WiFi (Wireless Fidelity), or a WiMAX (Worldwide Interoperability for Microwave Access). In this case, the access service system 300 may be configured to include an access point and an access router. Accordingly, the access service system 300 can provide the wireless terminal service to the terminal 400, and allow the terminal 400 to access the packet service system 100. Therefore, the terminal 400 capable of using the access service system 300 described above can access the packet service system 100 through the corresponding access service system 300. Meanwhile, in the embodiment of the present invention, as shown in FIG. 1, it is assumed that the access service system 300 includes a mobile access system base station, a base station controller, and a gateway. However, the connection service system 300 according to the embodiment of the present invention is not limited thereto, and the connection service system 300 of the fixed connection type or the wireless connection type may be used.

Particularly, in the embodiment of the present invention, the packet service system 100 is assumed to be IMS (IP Multimedia Subsystems). The packet service system 100 is composed of a plurality of entities, and each entity may be implemented as one device, or may be implemented as another device for each entity.

Entities of the packet service system 100 according to an embodiment of the present invention may include additional service controllers (TAS, Telephony Application Server 110), session controllers (CSCF, Call Session Control Function, 120), and home subscriber devices (HSS). Server 130 and media device 160. In particular, the media device 160 includes a Multimedia Resource Function Controller (MRFC) 140 and a Multimedia Resource Function Processor (MRFP) 150. Other entities of the packet service system 100 omit explanations to clarify the gist 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. A service profile includes a list of supplementary services to which a user subscribes, and each item in the list represents a service. Here, the service includes a basic service and an additional service. The additional service controller 110 can provide the corresponding additional service when the corresponding item in the service profile is activated. On the other hand, the additional service controller 110 can not provide the corresponding additional service when the corresponding item in the service profile is inactivated.

The session controller 120 establishes a session between each entity of the packet service system 100 and the terminal 400 and receives and processes the 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, thereby completing the session. The session controller 120 may include I (Interrogating) - CSCF, S (Service) - CSCF, and P (Proxy) - CSCF.

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

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

The INVITE message is a method for requesting a session connection between a device and a device. Here, the apparatus includes each entity of the terminal 400 and the packet service system 100. For the session connection, the INVITE message specifies the object of the session connection. Therefore, according to the embodiment of the present invention, the INVITE message includes a session connection request message for requesting a session connection for voice communication between the calling terminal 401 and the called terminal 402, As a broadcast session connection request message.

The ACK message is a method used as a response indicating that the device that received 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.

An INFO message is a method used to send and receive 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.

A BYE message is a method that is used to release an already connected session. Accordingly, the BYE message can be used as a broadcast session disconnect message for requesting release of a session connection for broadcasting.

According to SIP, the MESSAGE message is for instant messaging (IM, instant messaging) between devices. Thus, the MESSAGE message can 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.

The REGISTER message is basically a message used for registration purposes. In particular, in order to use the packet service system 100, the terminal 400 must register with the packet service system 100, and the REGISTER message includes information necessary for registration. Accordingly, the REGISTER message can be used as a registration request message for requesting registration of the called terminal 402 to the packet service system 100. Also, the REGISTER message can be used as a registration notification message to notify the supplementary service controller 110 that the terminating terminal 402 is registered in the packet service system 100.

Among the SIP messages, the 1xx series message (where xx is a natural number) is a kind of response message. The 1xx series messages are used to notify that a specific request message has been received and message processing is continuing. The supplementary service controller 110 transmits the 183 SessionProgress message to the calling terminal 401 because it needs to continue the session connection procedure to provide the announcement to the calling terminal 401. [ This 183 SessionProgress message informs that the session establishment procedure is still in progress. The additional service controller 110 can continue the session connection procedure for announcement broadcasting instead of session connection for voice communication by transmitting the 183 SessionProgress message. Therefore, the 183 SessionProgress message can be used as a session progress message to inform that the session is in progress.

Of the SIP messages, 2xx series messages (where xx is a natural number) are used to indicate success in response to a specific SIP message. In particular, a 200 OK message is used to indicate acceptance, acknowledgment of acknowledgment, acknowledgment, etc. for a particular message. Therefore, according to the embodiment of the present invention, the 200 OK message can be used as a broadcast session connection acceptance message for accepting 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 collecting an 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 disconnect acknowledgment message informing that it accepts it as a response to a broadcast session disconnect (BYE) message. The 200 OK message can be used as a registration acceptance message informing that the called terminal 402 accepts the REGISTER message in response to a REGISTER message requesting registration to the packet service system 100. In addition, the 200 OK message may be used as a registration confirmation message informing that the calling terminal 402 has confirmed it in response to a registration notification (REGISTER) message indicating that the called terminal 402 is registered in the packet service system 100.

Among the SIP messages, the 4xx series message (where xx is a natural number) is 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 can be used as a notification message during a call indicating that the session connection request can not be processed because the call 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.

408 The RequestTimeout message is used to notify that there is no response when there is no response for a predetermined time 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 that perform session control. The home subscriber device 130 stores the subscription information of the user related to the session control, that is, the location information of the user, the security information for authentication and permission of the user, and the service profile, which is a list of services to which the user subscribes.

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 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 multimedia resource controller 140 and the multimedia resource processor 150 may be implemented as independent devices or as a single device.

Next, the configuration of the circuit service system 200 according to the 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 the users 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 the services to which the user subscribes. This service includes basic services and additional services. 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 the service to which the user subscribes, the home location register 210 may store a service profile, which is a list of services to which the user subscribes. Each item in this list represents a service. If the item is activated, the corresponding service can be provided. If it is inactivated, the corresponding service can not be provided. The above-mentioned service includes a basic service and an additional service.

The intranet gateway 220 is a gateway between the supplementary service 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. The supplementary service controller 110 is interlocked with the home location register 210 through the intranet gateway 220 and the supplementary service controller 110 and the home location register 210 communicate with each other according to a MAP (Mobile Application Part) . The supplementary service controller 110 may receive and store the required service profile from the home location register 210. [ If the service profile received and stored from the home location register 210 is changed, the additional service controller 110 can deliver it to the home location register 210. In addition, the home location register 210 may transmit the changed service profile to the additional service controller 110 when the service profile stored therein is changed. Accordingly, the service profiles stored in the additional service controller 110 and the home location register 210 can be kept equal to each other.

2 is a diagram illustrating a configuration of an additional service controller for providing caller information according to an embodiment of the present invention.

2, the supplementary service controller 110 includes a communication module 10, a storage module 20, and a control module 30. [

Upon receiving data from the control unit 470, the wireless network communication unit 421 can access the connection service system 300 through the base station and transmit data. The wireless network communication unit 421 may access the connection service system 300 through the base station to receive data and provide the received data to the control unit 470.

The wireless LAN communication unit 422 is for performing communication according to a wireless LAN (WLAN), a WiFi, or a WiMAX scheme. When the wireless LAN communication unit 422 receives data from the control unit 470, the wireless LAN communication unit 422 can access the access service system 300 through an access point and transmit data. In addition, the wireless LAN communication unit 422 can access the connection service system 300 through the access point, and then receive the data and provide the received data to the control unit 470.

The wireless fan communication unit 423 is for transmitting and receiving data according to a wireless fan (WPAN) scheme, and is for exchanging data through a wireless communication with a shorter distance than the wireless network communication unit 421 and the wireless LAN communication unit 422 . The wireless fan communication unit 423 can directly transmit and receive data to and from the other terminals 400. [ In addition, when the wireless fan communication unit 423 can be connected to the gateway directly or through multi-hop, the wireless fan communication unit 423 can access the connection service system 300 through the gateway and transmit and receive data. Such a wireless fan communication unit 423 can exemplify communication based on Bluetooth, infrared communication (IrDA), ZigBee, or the like.

The wired communication unit 430 is for transmitting and receiving data by wire. The wired communication unit 430 can connect to the connection service system 300 via a wire, and can transmit and receive data. In particular, the access service system 300 connected through a wired network may be a network provided by an ISP (Internet Service Provider) or a private network. Here, the private network may represent a specific group of intra-networks representatively.

The input unit 440 may include a plurality of input keys and function keys for receiving numeric or character information and setting various functions, as means for receiving at least one of a command, selection, data, and information of a user. The input unit 440 senses the key input of the user and transmits an input signal corresponding to the sensed key input to the control unit 470. The input unit 440 may be an input device such as a keyboard, a keypad, a mouse, a joystick, and the like. For example, based on the announcement broadcast according to the embodiment of the present invention, the user may input the identification number of the calling terminal 401 through the input unit 440. Then, the input unit 440 may transfer the input identification number to the control unit 470.

The output unit 450 is a means for outputting a result or information according to the operation of the terminal 400. [ The output unit 450 may include a display device 451 for outputting visual information, and an audio device 453 for outputting auditory information. The display device 451 may be a touch screen. When the display device 451 is formed in the form of a touch screen, the display device 451 may display some or all of the functions of the input device 440 Can be performed. When the terminal 400 is the calling terminal 401, the announcement broadcast can be received through a session connected to the media device 160, and the audio device 453 may output the received announcement broadcast.

The storage unit 460 is an apparatus for storing data, and includes a main storage unit and an auxiliary storage unit. The storage unit 460 may store an operating system (OS), applications, and the like. In particular, the storage unit 460 may store the received SIP message. According to SIP, the handshake process of exchanging request and response messages between devices is repeated, so that stored SIP messages can be used to extract data for responding to a request. Each kind of data stored in the storage unit 460 can be deleted, changed, or added according to a user's operation.

The control unit 470 may be a processing apparatus that actually operates the operating system. For example, the control unit 470 may be a central processing unit (CPU). When the terminal 400 is powered on, the control unit 470 moves the operating system from the auxiliary storage unit of the storage unit 460 to the main storage unit, and then performs booting to drive the operating system.

The control unit 470 may generate various messages according to the SIP, and may transmit the generated messages through the communication unit 410. In addition, when the controller 470 receives the message according to the SIP, the controller 470 performs a necessary operation according to the type of the message.

In addition, when the session is connected to the media device 160, the controller 470 may control to output the guide broadcast received through the communication unit 410 through the output unit 450.

Then, the controller 470 may transmit the received identification number through the communication unit 410. At this time, the identification number may be transmitted in the form of a DTMF signal.

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 calling terminal 401 transmits a session connection request message to the session controller 120 in step S401. The session connection request message is for the calling terminal 401 to request a session connection for making a call with the called terminal 402. The session connection request message may use the 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 can use the INVITE message according to the 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 acceptance message may use the 200 OK message according to the 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 transmitted from the calling terminal 401, and is transmitted to the calling terminal 401 to inform that the session setting is still in progress. Such a session progress message may use the 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 calling terminal 401 may proceed to another procedure such as retrying the session connection request when the session request is denied, stopped, or terminated. However, the calling terminal 401 may not proceed with the above-described other procedure by receiving the Session Progress message.

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 informing that confirmation of the acceptance of the session connection for broadcasting is confirmed. The broadcast session connection acknowledgment 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 is to be delivered to the user of the calling terminal 401. 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 the session between the media device 160 and the calling terminal 401. Such a 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. Such a broadcast session disassociation acceptance message may use the 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 calling terminal 401 has made a call request. In response to the selection of the user of the called terminal 402, the calling terminal 401 can 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 calling terminal 401 to request a session connection for making 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 time expiration message is a message informing that there is no response from the called terminal 402 within a predetermined 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 calling terminal 401 to request a session connection for making 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 to the packet service system 100. This registration request message can use the REGISTER message according to the 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 unit 130 to request authentication of the called subscriber unit 402, and thus registration is completed when the home subscriber unit 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 the acceptance of the registration of the called terminal 402. Preferably, the registration accept message uses the 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 informing that the called terminal 402 is registered in the packet service system 100. The registration notification message can 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, in response to the registration notification (REGISTER) message, indicates that the registration of the called terminal 402 has been confirmed. This registration confirmation message can use the 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.
