Upon receiving the short message, the user of the called terminal confirms that the call is a transfer call, and if the call button is input, the called terminal transmits a call setup request signal to the exchange to make a callback connection to the service providing apparatus (step 1307). The exchange confirms that the call establishment request signal is a number for connection to the SCP and transmits an AI signal to the SCP (step 1309). The SCP confirms that the AI signal is for a transfer call service, and transmits an SR signal to the UCS-IP server for connection to the UCS-IP server (step 1311). The UCS-IP server transmits an sr signal including the TLDN to the SCP in response to the SR signal (step 1313). The SCP forwards the ConnectResource signal to the exchange for connection to the UCS-IP server based on the TLDN (step 1315).

The exchange sends a call connection request signal to a UCS-IP server based on the ConnectResource signal received (step 1317). The UCS-IP server sends a call connection response signal to the MSC in response to the call connection request signal (step 1319). The exchange sends a call setup response signal to the called terminal to form a call path between the UCS-IP server and the called terminal of the service providing apparatus (step 1321).

The UCS-IP server then sends an IR signal to the SCP for processing the call (step 1323). After confirming that the called party is the forwarding call confirmation subscriber, the SCP transmits an SRFD signal to the UCS-IP server to reproduce the recorded voice message (step 1325). The UCS-IP server confirms that the call is an incoming call to check voice, and takes a voice message left by the calling subscriber in the DB server and transmits the voice message to the called terminal (step 1327).

The UCS-IP server plays back all voice messages to be delivered and sends an srfd signal to the SCP (step 1329). At this time, after listening to the voice message received at the called terminal, the call can be answered without dismissing the call. The SCP sends an ir signal to the UCS-IP server indicating that the call has been processed (step 1333).

Upon receiving the ir signal, the UCS-IP server sends a call release signal to the exchange (step 1335). The SCP sends an ai signal to the exchange indicating that the processing of the AI signal received from the exchange is complete (step 1337). The exchange releases the call by sending a call release signal to the called terminal (step 1339).

The UCS-IP server sends a delivery call completion notification to the APS that the delivery call is completed to the called terminal (step 1341). The APS sends a short message to the SMSC, "completed for [delivery call] [recipient's phone number or name]" (step 1343). The SMSC sends the short message to the originating terminal (step 1345). Although not shown, the APS server transmits CDR data for charging to the charging system after the service is terminated.

14 is a signal flow diagram illustrating a procedure for checking a voice message by a transfer call service in a called terminal according to an embodiment of the present invention and then replying to the calling terminal using the transferred call. In this procedure, the calling subscriber listens to the recorded message of the calling subscriber in the procedure of attempting a voice delivery call by using the service node method, and then sends a reply to the calling subscriber by using the forwarding call. The procedure is illustrated. This procedure may change depending on the service provider's internal network or service procedure.

Referring to FIG. 14, the calling terminal accesses the service providing apparatus to record a voice message, and the service providing apparatus transmits the voice message to the called terminal so that the called subscriber listens to the recorded voice message recorded by the calling subscriber (step 1401). ). Here, step 1401 corresponds to steps 901 to 935 of FIG. 9 and steps 1001 to 1037 of FIG. 10. After the called subscriber listens to the voice message, the UCS-IP server of the service providing apparatus transmits a guide message for reply to the called terminal (step 1403). At this time, an example of the guide message may be "forwarding call forwarding 1, for caller direct connection 2, for caller call 3".

In the above example, 1 is selected from the called subscriber, and the called terminal transmits a transfer call response request signal to the UCS-IP server (step 1405). The UCS-IP server transmits a delivery call reception and completion notification message to the APS server indicating that the called party has completed listening after receiving the delivery call sent by the caller (step 1407). The APS server, for example, sends a text message to the SMSC such as "[Delivery call] [recipient's phone number or name completed]" (step 1409). The SMSC sends the text message to the calling terminal (step 1411). Although not shown, the APS server transmits CDR data for charging outgoing subscribers to the billing system after the service is terminated.

The UCS-IP server is a called terminal. For example, "Delivery call reply. Record after beeping and press * or # when finished. Send beep message" such as beep (step 1413). The transfer call of step 1413 corresponds to the response transfer call to the original transfer call. The called terminal sends a reply message to the calling terminal to the UCS-IP server (step 1415). At this time, the UCS-IP server can send a guide message such as "I will reply you. Thank you for using."

The UCS-IP server transmits the transfer call information (calling terminal number, called terminal number, time information, etc.) and voice reply message left by the called subscriber to the APS server and the DB server (step 1417). The UCS-IP server sends a call release signal to the exchange (step 1419). The exchange sends a call release signal to the called terminal to release the call path between the UCS-IP server and the called terminal of the service providing apparatus (step 1421).

The APS server of the service providing apparatus internally schedules a delivery call service to deliver data stored in the called terminal to the calling terminal, and brings data to be transmitted from the DB server (step 1423). In this case, the outgoing terminal immediately dials out after leaving a voice message. However, if the outgoing terminal does not receive a call, it needs to retry. Therefore, it is necessary to internally calculate the outbound call and time.

The APS server sends a transfer call request signal to the UCS-IP server (step 1425). The UCS-IP server attempts an outbound call to an exchange connected to E1 or T1 (step 1427). The exchange sends a call setup request signal to the calling terminal (step 1429), and receives a call setup response signal when the calling terminal responds (step 1431). The exchange transmits an outbound call response signal to the UCS-IP server in response to the call establishment response signal (step 1433), and a call path is formed between the UCS-IP server of the service providing apparatus and the calling terminal.

The UCS-IP server takes the voice message left by the called subscriber stored in the DB server (DBS) and transmits the voice message to the calling terminal using the call path (step 1435). After the UCS-IP server has played all voice messages, the UCS-IP server transmits a call release request signal to the exchange (step 1437), and the exchange transfers it to the calling terminal (step 1439). Is released.

The UCS-IP server sends a delivery call completion notification to the APS that the delivery call has been delivered to the calling terminal (step 1441). The APS sends a short message to the SMSC to inform the called terminal that it has completed delivery of the transfer call reply to the calling terminal (step 1443). The SMSC sends the short message to the called terminal (step 1445). Although not shown, the APS server transmits CDR data for charging to the charging system after the service is terminated.

15 is a signal flow diagram illustrating a procedure for directly connecting to a calling terminal after checking a voice message by a delivery call service in a called terminal according to an exemplary embodiment of the present invention. In this procedure, the calling subscriber listens to the recorded message of the calling subscriber in the procedure in which the calling subscriber tries to transfer the call using the service node method. It shows the procedure that takes place. At this time, the UCS-IP server of the service providing apparatus may receive a connection request directly from the called terminal and process an outbound call directly to make a call between the calling subscriber and the called subscriber. This procedure may change depending on the service provider's internal network or service procedure.

Referring to FIG. 15, the calling terminal accesses the service providing apparatus to record a voice message, and the service providing apparatus transmits the voice message to the called terminal so that the called subscriber listens to the voice message recorded by the calling subscriber (step 1501). ). Here, step 1501 corresponds to steps 901 to 935 of FIG. 9 and steps 1001 to 1037 of FIG. 10. After the called subscriber listens to the voice message, the UCS-IP server of the service providing apparatus transmits a guide message for reply to the called terminal (step 1503). At this time, an example of the guide message may be "forwarding call forwarding 1, for caller direct connection 2, for caller call 3".

In the above example, 2 is selected from the called subscriber, and the called terminal transmits a caller direct connection request signal to the UCS-IP server (step 1505). The UCS-IP server transmits a delivery call reception and completion notification message indicating that the called party has completed listening after receiving the delivery call sent by the caller (step 1507). The APS server sends a text message to the SMSC informing the delivery call completion notification, such as "Completed to [delivery call] [recipient phone number or name]" (step 1509). The SMSC sends the text message to the calling terminal (step 1511). Although not shown, the APS server transmits CDR data for charging outgoing subscribers to the billing system after the service is terminated.

The UCS-IP server attempts an outbound call to call the calling terminal to an exchange connected to E1 or T1 (step 1513). The exchange sends a call establishment request signal to the calling terminal (step 1515). The originating terminal sends a call setup response signal to the exchange in response to the call setup request signal (step 1517). The exchange transmits an outbound call response signal to the UCS-IP server in response to the call establishment response signal (step 1519), and a call path is formed between the calling terminal and the UCS-IP server of the service providing apparatus. At this time, the calling terminal and the called terminal perform a call using a call path between the existing UCS-IP server and the called terminal and the call path between the UCS-IP server and the calling terminal (step 1521).

The calling terminal sends a call release signal to the exchange to terminate the call on which the calling subscriber is busy (step 1523). The exchange forwards the call release signal to the UCS-IP (step 1525). The UCS-IP server sends a call release signal to the exchange to release the call with the called terminal (step 1527), and the exchange transmits the call release signal to the called terminal (step 1529). Of course, in step 1523 to 1529, the called terminal may transmit a call release signal to the exchange to release the call.

The UCS-IP server sends a delivery call reply completion notification to the APS (step 1531). At this time, although not shown, the APS server transmits CDR data to the billing system for billing of the called party or the calling party after the service is terminated.

16 is a signal flowchart illustrating a procedure of calling a calling terminal after checking a voice message by a delivery call service in a called terminal according to an exemplary embodiment of the present invention. FIG. 1 illustrates a procedure in which a calling party makes a call through an outgoing subscriber call after listening to a recorded message of the outgoing subscriber in a procedure in which an outgoing subscriber attempts a delivery call using a service node method. At this time, the UCS-IP server of the service providing device receives the calling party call request from the called party, releases the call with the called party, processes the outbound call directly, connects with the calling party, and then calls the called party. Call between the called party and the called party. This procedure may change depending on the service provider's internal network or service procedure.

The calling terminal connects to the service providing apparatus to record a voice message, and the service providing apparatus transmits the voice message to the called terminal so that the called subscriber listens to the voice message recorded by the calling subscriber (step 1601). Here, step 1601 corresponds to steps 901 to 935 of FIG. 9 and steps 1001 to 1037 of FIG. 10. After the called subscriber listens to the voice message, the UCS-IP server of the service providing apparatus transmits a guide message for reply to the called terminal (step 1603). At this time, an example of the guide message may be "forwarding call forwarding 1, for caller direct connection 2, for caller call 3".

In the above example, 3 is selected from the called subscriber, and the called terminal transmits a caller call request signal to the UCS-IP server (step 1605). The UCS-IP server sends a call release signal to the exchange to release the call with the called terminal (step 1607). The exchange sends a call release signal to the called terminal to release the call path between the UCS-IP server and the called terminal (step 1609).

The UCS-IP server transmits the delivery call reception completion notification message to the APS server after the called subscriber receives the delivery call sent by the caller (step 1611). The APS server sends a text message to the SMSC to inform the calling terminal of the completion of the delivery call transmission (step 1613), and the SMSC sends a text message to the calling terminal (step 1615). At this time, although not shown, the APS server transmits the CDR data to the billing system for outgoing subscriber billing after the service is terminated.

The UCS-IP server transmits the transfer call call information (called terminal number, called terminal number, time information, etc.) left by the called subscriber to the APS server and the DB server (step 1617). The APS server internally takes the data transfer call call information stored by the called party from the DB server and performs scheduling of the caller call (step 1619). At this time, after making a call request at the called terminal, it immediately dials out. However, if a call is not received at the calling terminal, it needs to retry. Therefore, it is necessary to internally calculate the call and time to outbound.

The APS server sends a transfer call call request signal to the UCS-IP server (step 1621). The UCS-IP server attempts an outbound call to an exchange connected to E1 or T1 (step 1623). The exchange sends a call setup request signal to the calling terminal (step 1625), and receives a call setup response signal in response (step 1627). The exchange sends an outbound call response signal to the UCS-IP server to form a call path between the calling terminal and the UCS-IP server of the service providing apparatus (step 1629). The UCS-IP server transmits and outputs a delivery call call notification message using a call path with the calling terminal (step 1631).

The UCS-IP server attempts an outbound call to an exchange connected to E1 or T1 to establish a call with the called terminal (step 1633). The exchange sends a call setup request signal to the called terminal (step 1635), and in response, receives a call setup response signal (step 1637). The exchange transmits an outbound call response signal to the UCS-IP server to form a call path between the called terminal and the UCS-IP server of the service providing apparatus (step 1639). The calling terminal and the called terminal make a call using the call path between the calling terminal and the UCS-IP server and the call path between the called terminal and the UCS-IP (step 1641).

The originating terminal sends a call release signal to the exchange to terminate the call on which the originating subscriber is busy (step 1643). The exchange forwards the call release signal to the UCS-IP (step 1645). The UCS-IP server sends a call release signal to the exchange to release the call with the called terminal (step 1647), and the exchange transmits the call release signal to the called terminal (step 1649). Of course, in step 1643 to step 1649, the called terminal may transmit a call release signal to the exchange to release the call.

The UCS-IP server sends a delivery call reply completion notification to the APS (step 1651). At this time, although not shown, the APS server transmits CDR data to the billing system for billing of the called party or the calling party after the service is terminated.

In order to provide a delivery call service according to the present invention, after receiving a voice message to be delivered from the calling terminal to the called terminal, the service providing apparatus needs a procedure for checking the status of the called terminal to deliver the voice message to the called terminal. . In order to deliver the voice message left by the calling terminal to the called terminal, the called terminal should be in an idle state. If the status of the called terminal is Out of range, Power Off, No answer or Busy, the service providing device determines the status of the called terminal and then The call is retried according to the set rescheduling method.

The method for checking the status of the called terminal is a method of inquiring a home location register (HLR) or a service controller (SCP) from a service providing device, and corresponds to a home location register (HLR) or a service controller (SCP). There is a method of registering a terminal status request, a method of using an ACM message among ISUP messages of SS7, and a method of using a CPG message of SS7 messages. Each of these methods will be described with reference to FIGS. 17 to 20.

17 is a signal flow diagram illustrating a procedure for checking a state of a called terminal by querying a home location register according to an exemplary embodiment of the present invention. Here, the home location register may be replaced with a service controller (SCP). In the method of checking the state of the called terminal described in this figure, when the APS server requests the state of the called terminal at a certain time to the home location register (HLR) or the service controller (SCP), the HLR or SCP determines the state of the called terminal. Refers to a method of transmitting a specific message (BRC) to the APS server.

Referring to FIG. 17, the calling terminal accesses the UCS-IP server of the service providing apparatus to store a voice message to be delivered to the called terminal, and the UCS-IP server transmits the call information to the DBS server and the APS server to transmit the call information. The storage of is completed (step 1701). Here, the step 1701 corresponds to steps 901 to 921 of FIG. 9, steps 1001 to 1021 of FIG. 10, and steps 1101 to 1139 of FIG. 11. Thereafter, the APS server obtains the delivery call information from the DBS and performs delivery call scheduling (step 1703).

The APS server transmits the called terminal status request signal to the HLR to determine the status of the called terminal according to the delivery call scheduling (step 1705). The HLR checks the state of the called terminal and transmits the called terminal status signal to the APS server (step 1707). The APS server determines whether the called terminal is in the standby state based on the called terminal status signal (step 1709). At this time, if the called terminal is in the standby state, steps after step 1711 are performed, and if the called terminal is not in the standby state, steps 1705 to 1709 are performed at regular intervals.

When the called terminal is in the standby state in step 1709, the APS server transmits a transfer call request signal to the UCS-IP server (step 1711). The UCS-IP server attempts an outbound call to an exchange connected to E1 or T1 (step 1713). The exchange sends a call setup request signal to the called terminal (step 1715) and, in response, receives a call setup response signal (step 1717). The exchange transmits an outbound call response signal to the UCS-IP server in response to the call establishment response signal (step 1719), and a call path is formed between the UCS-IP server of the service providing apparatus and the called terminal. The UCS-IP server transmits the voice message left by the calling subscriber to the called terminal using the call path (step 1721).

18 is a signal flow diagram illustrating a procedure for providing a delivery call service by a method of registering to a home location register when a called terminal is not in a standby state according to an exemplary embodiment of the present invention. The home location register (HLR) can be replaced with a service controller (SCP). The method for checking the state of the called terminal described in this figure is to request the state of the called terminal to the HLR or SCP, if the state of the called terminal is not in the standby state, the APS server when the called terminal is in the standby state to the HLR or SCP A method of registering to send a message to an APS server.

Referring to FIG. 18, the calling terminal stores a voice message to be delivered to the called terminal by accessing the UCS-IP server of the service providing apparatus, and the UCS-IP server transmits the call information to the DBS server and the APS server to transmit the call information. Is stored (step 1801). The step 1801 corresponds to steps 901 to 921 of FIG. 9, steps 1001 to 1021 of FIG. 10, and steps 1101 to 1139 of FIG. 11. Thereafter, the APS server obtains the delivery call information from the DBS and performs delivery call scheduling (step 1803).

The APS server transmits the called terminal status request signal to the HLR to determine the status of the called terminal according to the delivery call scheduling (step 1805). The HLR checks the status of the called terminal and transmits the called terminal status signal to the APS server (step 1807). The APS server determines whether the called terminal is in the standby state based on the called terminal status signal (step 1809). At this time, if the called terminal is in the standby state, steps after step 1819 are performed, and if the called terminal is not in the standby state, step 1811 is performed.

If the called terminal is not in the standby state in step 1809, the APS server transmits the called terminal state registration request signal to the HLR (step 1811). The HLR sends the destination terminal status registration result signal to the APS server (step 1813).

If the called terminal enters the standby state and is registered with the HLR (step 1815), the HLR transmits the state of the called terminal to the APS server (step 1817). At this time, the called terminal state corresponds to the standby state.

The APS server receiving the status of the called terminal transmits a transfer call request signal to the UCS-IP server (step 1819). The UCS-IP server attempts an outbound call to an exchange connected to E1 or T1 (step 1821). The exchange sends a call setup request signal to the called terminal (step 1823), and in response receives a call setup response signal (step 1825). The exchange transmits an outbound call response signal to the UCS-IP server in response to the call establishment response signal (step 1827), and a call path is formed between the UCS-IP server of the service providing apparatus and the called terminal. The UCS-IP server transmits the voice message left by the calling subscriber to the called terminal using the call path (step 1829).

19 is a signal flow diagram illustrating a procedure for checking a state of a called terminal using ACM according to an embodiment of the present invention. In the method of checking the state of the called terminal described in this figure, the APS server makes a forwarding call request to the UCS-IP server, and the UCS-IP server makes a call to E1 / T1 to perform a backward call of an ACM message received from a large station. This is a method to check the status of the called terminal by checking the value of the Called Party Status Indicator Field of the Indicator.

Referring to FIG. 19, the calling terminal accesses the UCS-IP server of the service providing apparatus to store a voice message to be delivered to the called terminal, and the UCS-IP server transmits the calling call information to the DBS server and the APS server to send the calling call information. The storage of is completed (step 1901). Here, the step 1901 corresponds to steps 901 to 921 of FIG. 9, steps 1001 to 1021 of FIG. 10, and steps 1101 to 1139 of FIG. 11. Thereafter, the APS server obtains the delivery call information from the DBS and performs delivery call scheduling (step 1903).

The APS server transmits a transfer call request signal to a UCS-IP server according to the transfer call scheduling (step 1905). The UCS-IP server sends an IAM (Initial Address Message) signal to the exchange (step 1907). The exchange transmits a Location Request (LOCREQ) signal to the Home Location Register (HLR) to determine the location of the terminating terminal (step 1909). The HLR sends a Routing Request (ROUTREQ) signal to the destination exchange (step 1911). The destination side exchange sends a routreq signal containing routing information (TLDN) to the HLR in response to the ROUTREQ signal (step 1913). The HLR sends a locreq signal containing a TLDN to the exchange in response to the LOCREQ signal (step 1915).

The exchange sends an IAM (Intial Address Message) signal to the destination exchange based on the TLDN (step 1917). The destination exchange sends an Address Complete Message (ACM) signal to the exchange (step 1919). In this case, the ACM signal includes a backward call indicator, and information on the state of the called terminal is included in a value of the Called Party Status Indicator Field of the backward call indicator. The exchange forwards the ACM signal to a UCS-IP server (step 1921). In this case, if the state of the called terminal is not in the standby state, the UCS-IP server does not proceed with the call and notifies the APS server that the call has failed. After that, the service providing apparatus retries the call according to retry scheduling. If the called terminal state is IDLE, then the called exchange sends an Answer Message (ANM) signal to the exchange (step 1923), and the exchange sends the ANM signal to the UCS-IP server (step 1925). Thereafter, the UCS-IP server transmits the voice message recorded by the calling subscriber to the called terminal (step 1927).

20 is a signal flow diagram illustrating a procedure for checking a state of a called terminal using a CPG according to an embodiment of the present invention. In the method of checking the state of the called terminal described in this figure, the APS server makes a transfer call request to the UCS-IP server, and the UCS-IP server generates a call to the E1 / T1 CPG message after the ACM message received from the large station. Is received, it is determined that the state of the called terminal is not the IDLE state.

Referring to FIG. 20, the calling terminal stores a voice message to be delivered to the called terminal by accessing the UCS-IP server of the service providing apparatus, and the UCS-IP server transmits the call information to the DBS server and the APS server to transmit the call information. The storage of is completed (step 2001). Herein, step 2001 corresponds to steps 901 to 921 of FIG. 9, steps 1001 to 1021 of FIG. 10, and steps 1101 to 1139 of FIG. 11. Thereafter, the APS server obtains the delivery call information from the DBS and performs delivery call scheduling (step 2003).

The APS server transmits a transfer call request signal to a UCS-IP server according to the transfer call scheduling (step 2005). The UCS-IP server sends an IAM (Initial Address Message) signal to the exchange (step 2007). The exchange transmits a Location Request (LOCREQ) signal to the home location register (HLR) to determine the location of the called terminal (step 2009). The HLR sends a Routing Request (ROUTREQ) signal to the destination exchange (step 2011). The destination side exchange sends a routreq signal containing routing information (TLDN) to the HLR in response to the ROUTREQ signal (step 2013). The HLR sends a locreq signal including a TLDN to the exchange in response to the LOCREQ signal (step 2015).

The exchange sends an IAM (Intial Address Message) signal to the destination exchange based on the TLDN (step 2017). The destination exchange sends an ACM (Address Complete Message) signal to the exchange (step 2019), and the exchange transfers the ACM signal to the UCS-IP server (step 2021).

If the called terminal state is busy or unanswered, the called party exchange sends a call progress (CPG) signal to the exchange (2023), and the exchange transmits the CPG signal to the UCS-IP server (step 2025). At this time, if the UCS-IP server receives the CPG signal from the exchange, the UCS-IP server determines that the status of the called terminal is busy or unanswered, and notifies the APS server that the call has failed and terminates the call. Thereafter, the device for providing a service may retry the call according to retry scheduling. If the called terminal state is IDLE, then the called side exchange sends an Answer Message (ANM) signal to the exchange (step 2027), and the exchange sends the ANM signal to the UCS-IP server (step 2029). That is, when the UCS-IP server receives the ANM signal without receiving the CPG signal, the UCS-IP server determines the state of the called terminal as a standby state, and the UCS-IP server transmits a voice message recorded by the calling subscriber to the called terminal ( Step 2031).

21 is a flowchart illustrating a scenario of a procedure for recording and transmitting a voice message to be transmitted from a calling terminal to a called terminal according to an embodiment of the present invention.

Referring to FIG. 21, first, a calling terminal receives a function code, a called terminal number, and a call button for a transfer call according to the present invention from a user and accesses a service providing apparatus (step 2101). The service providing device is a "caller name} transfer call to the calling terminal. Record after the beep sound, and when finished, press an asterisk or a well sperm. A beep message is output to the calling subscriber (step 2103). The user of the called terminal records a voice message to be delivered to the called terminal according to the guide message (step 2105). The service providing apparatus determines whether there is an interruption or the recording time has been exceeded by input of an asterisk or well sperm (step 2107). If there is an interruption as a result of the determination, step 2109 is performed. If recording time is exceeded, step 2109 is performed. In step 2109, the service providing device outputs a message of "We will send the message. Thank you for using."

In step 2109, the service providing device outputs a message to the calling subscriber (step 2109). Thereafter, when an asterisk or a well sperm is input (step 2111), step 2109 is performed, and when a predetermined key input time is exceeded, step 2115 is performed.

In operation 2115, the apparatus for providing a service determines whether a predetermined number of input attempts has been exceeded. As a result of the determination, if the number of input attempts is exceeded, step 2117 is performed. If the number of input attempts is not exceeded, the process returns to step 2109.

In step 2117, the device for providing a service outputs a message of "Transfer canceled" to the calling subscriber (step 2117). The call then ends (step 2119).

22 is a flowchart illustrating a scenario of a procedure of listening to a voice message in a called terminal according to an embodiment of the present invention.

Referring to Fig. 22, the called terminal receives a call for receiving a transfer call from the service providing apparatus (step 2201). The service providing apparatus determines whether a nick name of the calling subscriber exists (step 2203). As a result of the determination, step 2205 is performed when the nickname does not exist, and step 2207 is performed when the nickname exists.

If the nickname does not exist, the service providing device outputs a message of "It is a {business name} delivery call." To the called subscriber (step 2205). If the nickname exists, the service providing device outputs a message of "This is a forwarding call of {Hong Gil Dong}" to the called subscriber (step 2207). In this case, {Hong Gil Dong} corresponds to the nickname set by the calling subscriber and is converted into voice by the TTS server of the service providing apparatus.

Thereafter, the apparatus for providing a service outputs and plays a voice message recorded by the calling subscriber to the called subscriber (step 2209).

In step 3813, the service providing device outputs a message to the user, "Press the new password four digits." After receiving the four-digit password from the user, the service providing device outputs a message "Please enter the four-digit password again" to the user (step 3817). At this time, the device for providing a service receives a 4-digit password again from the user and checks whether the password matches (step 3817). If the passwords match, step 3819 is performed, and if the passwords do not match, the process returns to step 3813. In step 3819, the service providing apparatus stores the new password in the database DB (step 3819) and returns to step 3807.

In step 3821, the service providing device outputs a message to the user, "Please use the web or MagicN for address book management", and returns to step 3807.

In operation 3823, the service providing apparatus outputs a message of "Message call charging management" to the user, and then determines whether the reply caller rate is set (step 3825). If the reply sender rate is set here, it means that the person responsible for the reply bears the charge for the reply. If it is determined that the reply sender fee is not set, step 3827 is performed. If the reply sender fee is set, step 3831 is performed. In step 3827, the device providing the service outputs a message to the user, "Currently, the person who responds to the message call is required to pay a fee. If you want this person to respond, please press 0." do. If 0 is input by the user, the service providing apparatus sets the reply caller fee (step 3829), and returns to step 3807. In step 3831, the service providing device outputs a message to the user, "Currently, the person who responds to the message call is required to pay the fee. If you want to receive the reply, please press 0." At this time, if 0 is input by the user, the service providing apparatus releases the reply caller fee (step 3833) and returns to step 3807.
