The APS server of the service providing apparatus internally schedules a delivery call service to deliver data stored by the calling subscriber to the called subscriber, and brings data to be delivered from the DB server (step 533). At this time, the outgoing subscriber immediately dials out after leaving a voice message. However, if the called subscriber does not answer the call, the outgoing subscriber needs to retry.

The APS server transmits a delivery call outbound call request signal to the UCS-IP server (step 535). The UCS-IP server attempts an outbound call to an exchange connected to E1 or T1 (step 537). The exchange transmits a call setup request signal to the called terminal (step 539), and receives a call setup response signal in response (step 541). The exchange transmits an outbound call response signal to the UCS-IP server in response to the call establishment response signal (step 543), and a call path is formed between the UCS-IP server of the service providing apparatus and the called terminal.

The UCS-IP server takes the voice message left by the calling subscriber stored in the DB server and transmits the voice message to the called terminal using the call path (step 545). After the UCS-IP server has played all the voice messages, the UCS-IP server transmits a call release request signal to the exchange (step 547), and the exchange transfers it to the called terminal (step 549) to transfer the call between the service providing device and the called terminal. Is released. At this time, if the incoming customer wants to reply without releasing the call after listening to the transfer call received from the caller, the caller can deliver the call transfer reply by voice to the caller. At this time, the reply transfer call may be delivered to the calling terminal by the process of step 521 to step 545, where the called terminal will correspond to the calling terminal.

The UCS-IP server transmits information (message) to the APS indicating that the called subscriber has completed listening after receiving the transfer call sent by the caller (step 551). The APS sends a short message to the SMSC, "Completed to [delivery call] [recipient's phone number or name]" (step 553). The SMSC sends the short message to the calling terminal (step 555).

6 is a signal flow diagram illustrating a procedure for providing a reservation call service according to an exemplary embodiment of the present invention.

Referring to FIG. 6, steps 601 to 613 show a reservation call registration procedure, and steps 615 to 643 show a reservation call call process through an outbound call using information reserved by an originating terminal. It is shown. First, the emitting terminal receives a telephone number and a wireless internet connection button (magic key, Nate or EZ-I key) of the called terminal from the user and accesses the WWAS server of the service providing apparatus (step 601). The WWAS transmits the main page of the wireless Internet capable of making a functional call with the called terminal to the calling terminal, and the calling terminal outputs it to the display unit (step 603). The calling terminal receives the corresponding number for performing the reservation call function from the wireless Internet main page from the user and transmits a reservation call request signal to the WWAS (step 605). In order to register the reservation call, the WWAS provides a screen for inputting a reservation date, time zone, etc. to the calling terminal (step 607). The WWAS may provide a menu such as a date and time for setting a reservation call (after 10 minutes, after 30 minutes, after 1 hour), or a time input window for a subscriber to enter, a name window of a called customer. In the case of the called party's telephone number for the reservation call, the called party's number input in step 601 may be used, and there is no need to provide an input window separately. The calling terminal receives reservation information such as a date, a time zone, and a called customer name from the user to the called party and transmits it to the WWAS (step 609). The WWAS transmits the reservation information to the DB server, and the DB server stores it (step 611). Thereafter, the wireless Internet connection between the calling terminal and the service providing device is released (step 613).

The APS of the service providing apparatus schedules a reservation call for reservation call processing (step 615). The APS reads the reservation information stored in the DB server (step 617). The APS server transmits a reserved call request signal including a called number and a calling number corresponding to the reserved call to the UCS-IP server (step 619).

The UCS-IP server of the service providing apparatus transmits an outbound call request signal to the exchange (step 621). Here, the outbound call request signal corresponds to a call connection request signal transmitted from the UCS-IP server to the exchange in order to make a call from the UCS-IP server to the calling terminal. The exchange transmits a call setup request signal to the calling terminal in response to the outbound call request signal (step 623), and receives a call setup response signal in response (step 625). The exchange transmits an outbound call response signal to the UCS-IP server of the service providing apparatus in response to the call establishment response signal (step 627). Here, the outbound call response signal corresponds to a call connection response signal in response to the outbound call request signal.

The UCS-IP server sends the name of the called subscriber (Text) to the TTS server to convert to voice (step 629). The UCS-IP server transmits call reservation information, that is, a reservation call guide message, to the called terminal to the calling terminal (step 631). Here is an example of the reservation call guide message, I will call "Hong Gil-dong". Press 1 for connection, 2 for cancel, and 3 for retry after [x] minutes. "If a specific number is selected and entered from the calling subscriber according to the reservation call guide message, The terminal transmits a DTMF signal to the UCS-IP server (step 633.) If the DTMF signal corresponds to a signal for reserved call connection, the UCS-IP server sends an outbound call request signal to the exchange to make a call to the called terminal. (Step 635) The exchange transmits a call setup request signal to the called terminal in response to the outbound call request signal (step 637), and in response receives a call setup response signal from the called terminal (step 639). The exchange sends an outbound call response signal to the UCS-IP server in response to the call establishment response signal (step 641).

By the above process, a call path is formed between the calling terminal and the called terminal, and a voice call is made between the calling subscriber and the called subscriber (step 643). After the call is terminated, the voice call is terminated and the UCS-IP server of the service providing apparatus may charge the reservation call by transmitting the usage record to the billing system.

It is shown. First, the emitting terminal receives a telephone number and a wireless internet connection button (magic key, Nate or EZ-I key) of the called terminal from the user and accesses the WWAS of the service providing apparatus (step 701). The WWAS transmits the main page of the wireless Internet capable of making a functional call with the called terminal to the calling terminal, and the calling terminal outputs it to the display unit (step 703). The calling terminal receives the corresponding number for performing the reservation call function from the main page of the wireless Internet from the user and transmits a reservation call request signal to the WWAS (step 705). In order to register the reservation call, the WWAS provides a screen for inputting a reservation date and time zone to the calling terminal (step 707). The WWAS may provide a menu such as a date and time for setting a reservation call (after 10 minutes, after 30 minutes, after 1 hour), or a time input window for a subscriber to enter, a name window of a called customer. In the case of the called party's telephone number for the reservation call, the called party's number input in step 701 may be used, so that an additional input window is not required. The calling terminal receives reservation information such as a date, a time zone, and a called customer name from the user to the called party and transmits it to the WWAS (step 709). The WWAS transmits the reservation information to the DB server, and the DB server stores it (step 711). Thereafter, the wireless Internet connection between the calling terminal and the service providing device is released (step 713).

The APS of the service providing apparatus schedules a reservation call for reservation call processing (step 715). The APS reads the reservation information stored in the DB server (step 617). The APS sends a short message (SMS) to the SMSC to inform the calling subscriber of the reservation call (step 719), and the SMSC forwards the short message (SMS) to the calling terminal (step 721). Here, the short message includes an identifier (telephone number) of the receiving terminal for making a callback connection to the called terminal. The calling terminal transmits a callback connection request signal to the exchange to make a call to the called terminal using the short message (step 723). The exchange transmits a call setup request signal to the called terminal in response to the callback connection request signal (step 725), and receives a call setup response signal in response (step 727). The exchange sends a callback connection response signal to the calling terminal in response to the call setup response signal (step 729). By the above process, a voice call is made between the called subscriber and the calling subscriber by using a call path formed between the calling terminal and the called terminal (step 731).

The originating terminal transmits a call establishment request signal to the exchange for connection with the UCS-IP server of the service providing apparatus to leave a voice message of the voice memo call (step 809). At this time, the telephone connection number of the service providing apparatus to the UCS-IP server is included in the WML or ME page outputted from the WWAS. The exchange transmits a call connection request signal to the UCS-IP server of the service providing apparatus according to the call establishment request signal (step 811). The UCS-IP server sends a call connection response signal to the exchange in response to the call connection request signal (step 813). The exchange establishes a call path between the originating terminal and the UCS-IP server of the service providing apparatus by transmitting a call setup response signal to the originating terminal in response to the call connection response signal (step 815). The UCS-IP server transmits a voice memo call announcement message to the calling terminal using the call path (step 817). As an example of the voice memo call guide message, "Voice memo call service. Record after the 'beep' sound and press '*' / '#' when finished. The calling terminal transmits the voice message to be delivered to the called terminal to the UCS-IP server, and receives a # (or *) key from the user (step 819). At this time, UCS-IP server can send a recording message (for example, "I will send a voice memo. Thank you for using.") After the recording to the calling terminal.

The UCS-IP server transmits voice memo call information (calling terminal number, called terminal number, time left for voice memo, etc.) and voice memo message left by the calling subscriber to the APS of the service providing apparatus (step 821), and the APS Transfer to DB server and save (step 823). The UCS-IP server sends a call release signal to the exchange (step 825), and the exchange transmits it to the calling terminal to release the call (step 827).

The calling terminal releases the telephone connection with the service providing apparatus and then reconnects to the WWAS of the service providing apparatus over the wireless Internet (step 829), and terminates the reconnected wireless internet when there are no additional services to use (step 831).

The APS then sends a short message to the SMSC to inform the called terminal that the voice message has arrived from the calling terminal (step 835), and the SMSC sends the short message to the called terminal (step 837). The called terminal transmits a call setup request signal to the exchange to access the UCS-IP server of the service providing apparatus using the call back URL information included in the short message (step 839). The exchange sends a call connection request signal to the UCS-IP server in response to the call establishment request signal (step 841), and receives a call connection response signal in response (step 843). The exchange transmits a call establishment response signal to the called terminal in correspondence with the call connection response signal (step 845). Using the call path formed between the UCS-IP server and the called terminal in steps 839 to 845, the UCS-IP server takes the voice memo message stored in the DB server and transmits it to the called terminal (step 847). ).

After the UCS-IP server transmits all voice memo messages, the UCS-IP server transmits a call release request signal to the exchange (step 849), and the exchange transfers it to the called terminal (step 851), so that the call between the service providing device and the called terminal is transmitted. The furnace is released. At this time, if the called terminal wants to reply without releasing the call after listening to the voice memo message received from the calling terminal, the caller may transmit a memo call reply to the caller by voice.

The UCS-IP server sends information (voice memo call completion notification message) indicating that the called terminal has received the voice memo message to the APS (step 853). The APS sends a short message to the SMSC, "The message has been received by [voice memo call] [recipient phone number or name]" (step 855), and the SMSC sends it to the calling terminal (step 857).

9 is a signal flowchart illustrating a call routing procedure from a calling terminal to a service providing apparatus according to an exemplary embodiment of the present invention. That is, in FIG. 9, the calling terminal accesses the WWAS of the service providing apparatus, selects a corresponding call service, terminates the connection with the WWAS, and leaves a voice message to the UCS-IP server of the service providing apparatus. It is a figure for demonstrating the connection procedure in detail.

Referring to FIG. 9, when a corresponding menu (eg, voice memo call) is selected by a user in a wireless Internet page provided by a WWAS of a service providing device, the calling terminal may call using the call back number included in the menu. The setup request signal is sent to the exchange (step 901). Here, the call back number is an ARS representative number (eg, 016-200-1234) for accessing the UCS-IP server of the service providing apparatus.

The exchange sends a location information request signal (LOCREQ) to the home location register (HLR) to determine the location of the called party (step 903). The home location register identifies the location of the called party and transmits a location information response signal (locreq) to the exchange (step 905). The location information response signal includes address information for routing to the UCS-IP server of the service providing apparatus.

The exchange sends an initial address message (IAM) to the UCS-IP server based on the location information response signal (step 907). The UCS-IP server sends an initialization complete message (ACM) and a response message (ANM) to the exchange in response to the call initialization message (step 909, step 911). Here, the call initialization message and the initialization completion message are signals for establishing a call path between the exchange and the UCS-IP server, and correspond to a call connection request signal and a call connection response signal, respectively.

After that, the UCS-IP server transmits a service information request signal to a DB server to obtain service information for providing an additional service selected by a user of the calling terminal, based on the calling party identifier and the called party identifier included in the call initialization message. (Step 913). The DB server sends a service information response signal to the UCS-IP server (step 915).
