Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing the configuration of a system for providing a voice message service between countries according to an exemplary embodiment of the present invention. Referring to FIG. 1, the voice message service system between countries according to the present invention (hereinafter referred to as "international message call"). Service system) (100) includes an IP (Intelligent Peripheral) server 101, a web server (WMAS: Web / ME Application Server, 109), a TTS (Text-To-Speech) server 105, and an APS (Application). Plus Server, 103, Database Server 107, Charging Data Recording (CDR) 111, and Charging Processing Unit 113.

The IP server 101 performs call processing for the international message call service of the present invention by interworking with the switch 200 and the international gateway switch 220 of the mobile communication network as E1 / T1, and performs an E1 / T1 voice. A processing device and a signal processing device.

The APS 103 schedules transmission of a voice message recorded by the caller or a voice message converted from the text message prepared by the caller. In addition, in conjunction with the SMSC (Short Message Service Center) 260, the billing processing device 113, and the like performs SMS transmission, billing processing, subscriber registration and authentication.

The TTS server 105 receives the text message transmitted from the caller, converts the text included in the text message into a speech, and stores the converted speech data in the database server 107.

The database server 107 stores and manages data used in the international message call service system according to the present invention, such as monthly subscriber information and voice message information, and records the voice data converted by the TTS server 105 and the caller. Stores one voice data. In particular, the database server 107 stores recording profile information such as address information, capacity information, recording date and time information, country code of the called party, and telephone number of the called party's terminal.

The billing recording device 111 receives a record of service usage from the IP server 101 and stores it for each subscriber when the subscriber uses services such as international voice message transmission, international call reservation, and international call recording. That is, the billing recording device 111 stores an international voice message, an international call reservation, a call recording service usage record for each subscriber, and aggregates the record on a monthly basis and transfers the record to the billing processing device 113. Alternatively, the service usage record may be transmitted to the charging processing device 113 whenever the service usage record is received from the IP server 101 according to the service type.

The billing processing unit 113 stores the monthly fee information and the service fee policy information for each subscriber, and receives the service fee for each subscriber from the billing recorder 111 and records the monthly fee information for each subscriber and the service usage record. Based on this, the monthly fee will be deducted from the subscriber, and if the monthly fee is exceeded, additional charges will be settled and billed to the subscriber according to the service-specific charge policy.

Here, the following example may be applied to the monthly fee information for each subscriber. In other words, if you sign up for a monthly fee of 20,000 won, you can make international phone calls up to 25,000 won, additionally 20 free voice messages (or 30 minutes of free recording), 30 free reservation services, and 30 minutes of free recording of your call (or 20 free call recordings). In addition, separate monthly fee services may be provided for voice message transmission, reservation service, and call recording. This can be selected according to the service policy. For example, the service charge policy may include 150 won per 15 seconds for voice message transmission, 50 won per case for reservation service, and 100 won per 15 seconds for call recording.

Meanwhile, the billing recording device 111 and the billing processing device 113 will be described in a separate configuration, but according to the service type, the billing recording device 111 and the billing processing device 113 may be implemented as a single device. . Hereinafter, the charging recording apparatus 111 and the charging processing apparatus 113 will be described as separately implemented.

Referring to the function and operation of each component of Figure 1 in more detail.

First, IP server 101 relays an international telephone call between a domestic caller and a foreign recipient. That is, when a caller who subscribes to the international monthly phone service enters an international call identification number (for example, "00345"), a country code, and a called party's telephone number on the calling terminal, the IP server 101 switches to an exchange ( Receives an international call connection request from the originating terminal of the domestic caller via 200, and in response, forms a call path with a called party terminal of another country through the international switching network 300 to establish a communication path between the domestic caller and the called party of the other country. Make international calls possible. However, there is a case that it is difficult to call because the telephone number of the foreign recipient is too long and the country code is not remembered. Therefore, the IP server 101 can directly connect to the last called party of another country even if the caller presses only the international telephone identification number, or guides the country code so that the caller can input the country code by voice. This may be accomplished by storing a recent call list or the like for each caller's telephone number in the database server 107.

On the other hand, after a call connection is made between a domestic caller and a receiver of another country, the IP server 101 makes a real-time charge payment based on monthly subscriber monthly payment information stored in the database server 107. When the caller's monthly fee is exhausted, the IP server 101 blocks the caller's international call, or calculates the information on the monthly fee exceeded charge and records it in the billing recorder 111 so that the charge exceeded the limit. To be done. This can be selected according to the service policy.

In addition, IP server 101 immediately or reserves a voice message recorded by a caller who subscribes to international monthly phone service, or a voice message converted from a text message written by the caller to a recipient terminal of another country through the international exchange network 300. send. That is, the voice message is transmitted through an outbound call directly to the called terminal through the international gateway exchange 220 and the international exchange network 300. Here, the outbound call means that the IP server 101 processes the outgoing call actively, that is, makes a call.

The caller may record the voice by connecting to the web server 109 via the wired or wireless Internet and recording, or by transmitting a predetermined function code (eg, "* 01" to the voice recording immediately, "* 02"). Can be recorded by directly connecting to the IP server 101 by inputting a voice recording reservation transmission. Alternatively, when a caller in another country is in a state of incapable of making calls during international calls, a voice may be recorded in the IP server 101 by inputting a DTMF shortcut key. The voice message recorded as described above is stored in the database server 107 together with the voice message information.

In addition, IP server 101 connects the calling terminal with the called terminal of another station at the call reservation time set by the caller. That is, the IP server 101 forms a call path with the caller terminal through the call exchanger 200, and forms a call path with the callee terminal of another country through the international gateway exchange 220 and the international exchange network 300. The caller terminal and the caller terminal are connected by mixing the caller side and the caller side. As a method of setting the call reservation time, the caller enters a predetermined function code (for example, "* 03") to connect to the IP server 101 and immediately set the call reservation time, or when making an international call, When the called party is in a call unavailable state, a call reservation time may be set in the IP server 101 by inputting a DTMF shortcut key. The call reservation time information set in this way is stored in the database server 107.

The APS 103 schedules the voice message transmission or the call connection according to the voice message transmission scheduled time stored in the database server 107 or the call connection reservation time, and transmits the voice message to the IP server 101 upon arrival of the corresponding time. Request or request a call connection between the caller and the called party.

The TTS server 105 works with the IP server 101 and the web server 109 to convert text messages into voice messages. That is, when the sender sends a text message through the calling terminal, the IP server 101 converts the text message into a voice message in association with the TTS server 105 and stores the text message in the database server 107. In addition, when the caller connects to the web server 109 to compose a text message, the web server 109 works with the TTS server 105 to convert the created text message into a voice message and stores the text message in the database server 107.

As described above, the database server 107, as described above, the international monthly payment service subscriber information, the voice message recorded by the caller, the voice message converted from the text message, the call connection reservation time, and the information of the voice messages (caller's telephone number, incoming call) Country code, called phone number, recording time, transmission reservation time, conversion time, etc.).

The billing recording device 111 receives a record of the service usage from the IP server 101 and stores it for each subscriber when the subscriber uses the international telephone, the international voice message transmission, the international telephone reservation, or the international telephone recording service. For example, when a subscriber uses international telephones exceeding the monthly amount, the billing recording device 111 receives and stores the international telephone usage information of the subscriber from the IP server 101. In addition, when the subscriber uses the international voice message service, the billing recording device 111 receives the voice message recording time of the subscriber from the IP server 101 and stores it in correspondence with the subscriber information. Alternatively, when the subscriber uses the international telephone recording service, the billing recording device 111 receives the recording time of the subscriber from the IP server 101 and stores it in correspondence with the subscriber information. When the subscriber uses the international telephone reservation service, the billing recording device 111 receives the usage information from the IP server 101 and stores the usage information in correspondence with the subscriber information.

The billing processing unit 113 stores the monthly fee information and the service fee policy information for each subscriber, and receives the service fee for each subscriber from the billing recorder 111 and records the monthly fee information for each subscriber and the service usage record. Based on this, the monthly fee will be deducted from the subscriber, and if the monthly fee is exceeded, the fee will be settled and billed to the subscriber according to the service-specific charge policy. If the subscriber's service fee does not exceed the monthly fee, the balance can be carried over to the next month. Carryover information is stored on the database server.

2 illustrates a concept of transmitting a voice message to a called party terminal of another country through the Internet network in the international message call service system according to an exemplary embodiment of the present invention.

2, the IP server 101 transmits the voice message recorded by the caller to the international message call service system 400 installed in another station through the Internet network, and the international message call service system 400 installed in the other station is The outbound call is processed directly to the called party terminal to play the voice message, or the SMS message is sent to the called party terminal to notify that the voice message has been received. At this time, the SMS message includes a callback number (Callback Number) of the international message call service system 400 installed in another country. In this case, the international message call service system 400 does not necessarily need to be installed in another station, and any device capable of delivering a voice message by performing outbound call processing to a called terminal may be used without limitation.

3 is a flowchart illustrating a procedure of transmitting an outbound call to a destination terminal of another station by processing an outbound call of a voice message recorded by an international monthly service provider according to an embodiment of the present invention.

As shown in FIG. 3, when a caller who first subscribes to a monthly service wants to send a voice message to a caller of another country, the caller sends a feature code (eg, * 01) to a voice message to a terminal. , And attempts to call by inputting an identification number indicating an international call (for example, 00345, hereinafter referred to as an international call identification number), a destination country code, and a phone number of a destination terminal. Then, the calling terminal establishes a call path by connecting to the IP server 101 via the switch 200 (S301).

At this time, the calling side exchange 200 recognizes that the call is for accessing the international message call service system based on the international telephone identification number and routes the calling terminal to the IP server 101 of the international message call service system.

After the call path is formed between the calling terminal and the IP server 101, the IP server 101 recognizes that the call is a voice message transmission based on the function code and transmits a recording guide message to the calling terminal (S303). ). In other words, the guide message is "KTF international message call. Record after the beep and press the well sperm when finished. For example, beep."

Subsequently, the calling terminal receives the voice from the user and transmits the voice to the IP server 101, and the IP server 101 records the transmitted voice (S305). At this time, the IP server 101 may transmit a recording completion guide message to the calling terminal after the recording is finished.

The IP server 101 stores the recorded voice message and information of the recorded voice message in the database server 107 (S307). Here, the information of the recorded voice message includes the calling terminal phone number, called country code, called terminal phone number, voice recording time, and the like.

Subsequently, the IP server 101 transmits a guide message for reservation transmission to the calling terminal (S309), and receives a response thereto (S311). For example, "Please press 1 for instant delivery and 2 for reservation". When the caller selects a reservation transmission, the IP server 101 receives a response by transmitting a guide message for setting a reservation time to the calling terminal.

Subsequently, IP server 101 transmits a call end signal to originating exchange 200 to release the call with the originating terminal, and originating exchange 200 transmits a call end signal to the originating terminal to communicate with the originating terminal. Release the channel (S313).

Subsequently, the IP server 101 transmits the caller's voice message usage information (for example, the recording time) to the charging recording device 111 (S315). The billing recording device 111 stores the voice message usage information received from the IP server 101 in correspondence with the caller's telephone number, and transmits the caller's telephone number and the caller's voice message usage information to the billing processing apparatus 113. (S317). At this time, the billing recording device 111 aggregates the voice message service usage history of the subscriber on a monthly basis and transmits it to the billing processing device 113, or the billing processing device 113 whenever the subscriber uses the voice message service. Can be sent to. This can be selected according to the service type.

The billing processing unit 113 calculates the caller's fee with reference to the monthly fee information for each subscriber stored therein and the information received from the billing recording device 111 (S319). That is, depending on the sender's voice message usage time (or depending on the number of voice message usage), the monthly fee (or monthly fee available) is subtracted, and the remaining monthly fee (or monthly fee available) is carried forward to the next month. In addition, additional charges (or number of voice message usage) exceeding the limit will be settled and billed.

On the other hand, when the sender selects the transmission immediately in step S311, IP server 101 transmits the outbound call setup request signal to the international gateway switch 220 that is connected to E1 or T1 (S321), the international gateway switch ( 220 transmits a call connection request signal to an exchange of another station through the international exchange network 300 according to the outbound call setup request signal of the IP server 101 (S323).

The exchange of another station transmits a call setup request signal to the called terminal (S325), and receives a call setup response signal from the called terminal (S327). Subsequently, the exchange of another station transmits a call connection response signal to the international gateway exchange 220 through the international exchange network 300 (S329).

The international gateway switch 220 that receives the call connection response signal from the exchange of another station through the international exchange network 300 transmits an outbound call setup response signal to the IP server 101 (S331). As a result, a call path is formed between the IP server 101 and the destination terminal of another station.

The IP server 101 loads the voice message recorded by the calling subscriber stored in the database server 107 and plays the voice message to the called terminal through the formed call path (S333).

After reproducing all voice messages, the IP server 101 transmits a call termination signal to the international gateway exchange 220, and the international gateway exchange 220 transmits a call termination signal to an exchange of another country through the international exchange network 300. do. The exchange of the other station receiving the call end signal transmits the call end signal to the called terminal and finally releases the call path between the IP server 101 and the called terminal of the other station (S335).

On the other hand, when the caller selects the scheduled transmission in step S311, the APS 103 for scheduling the voice message transmission requests the IP server 101 to the IP server 101 when the scheduled transmission time arrives set by the caller. The IP server 101 performs the above-described steps S321 to S335.

After the call between the IP server 101 and the destination terminal of the other station is released, the IP server 101 notifies the APS 103 of the completion of the voice message transmission, and the APS 103 receiving the notification receives the voice message transmission completion message. It can be written and sent to the calling terminal through the SMSC (260).

Figure 4 illustrates a procedure for a caller making an international call by setting an international call reservation time according to a preferred embodiment of the present invention.

As shown in Fig. 4, first, when a caller wants to make an international call with a foreign party, a feature code (for example, * 02), an international call identification number, a destination country for setting a call reservation in a terminal The number and the telephone number of the called terminal are input to access the IP server 101 of the international message call service system (S401). This process is the same as step S301 of FIG. 3, and thus a detailed description thereof will be omitted.

After the call path is formed between the calling terminal and the IP server 101, the IP server 101 recognizes that the call is a call reservation service based on the function code and transmits a call reservation setting guide message to the calling terminal. (S403). For example, "KTF is an international message call. After 1 hour, press 1 for reservation settings and 2 for specific time reservations."

Subsequently, the calling terminal receives the call reservation time from the user and transmits it to the IP server 101 (S405), and the IP server 101 stores the call reservation information in the database server 107 (S407). In this case, the IP server 101 may transmit a setting completion guide message to the calling terminal after the reservation setting is completed. Here, the call reservation information includes the calling terminal phone number, called country code, called terminal phone number, call reservation time (including date), and the like.

Subsequently, the IP server 101 transmits a call release signal to the calling terminal through the switch 200 to release the call with the calling terminal (S409), and sends the caller information and the corresponding caller's international information to the charging recorder 111. The telephone reservation fact is transmitted (S411). The accounting recording device 111 correspondingly stores caller information transmitted from the IP server 101 and the fact that the caller has made an international call reservation. Then, the billing recording device 111 transmits the caller's international call reservation service usage history to the billing processing device 113 (S413). Transmission of the service usage history may be collectively transmitted on a monthly basis, or may be immediately transmitted whenever the subscriber uses the service. This can be selected according to the service policy. The billing processing unit 113 calculates the caller's fee by referring to the monthly fee information per subscriber, that is, the number of reservation service available and the usage history received from the billing recording device 111 (S415). The number of monthly flat-rates will be subtracted by the number of caller's reservations, and if the limit is exceeded, additional charges will be made according to the billing policy for each service. Otherwise, if the number of reservation service usage is within the monthly limit, the remaining available number is carried over to the next month for reuse.

Thereafter, the APS 103 in charge of scheduling makes a call connection request to the IP server 101 according to the call reservation time stored in the database server 107 (S417). At this time, the call connection request signal includes a calling terminal telephone number, a called country code, a called terminal telephone number, and the like.

First, the IP server 101 transmits a call setup request signal to the calling terminal through the calling side switch 200 according to the call connection request of the APS 103 (S419), and at the call response of the calling terminal (S421), A guide message confirming whether or not to make a reservation call is transmitted to the calling terminal (S423).

When the caller accepts the reserved call (S425), the IP server 101 transmits the ring back tone to the calling terminal (S427), and then, through the international gateway exchange 220 and the international exchange network 300, the called party exchange of another country ( In step S429, the call setup request signal is transmitted.

The destination side exchange 320 of the other station transmits a call setup request signal to the destination terminal, and receives a response signal thereto (S431). The destination exchange 320 of the other station transmits a call setup response signal to the IP server 101 via the international exchange network 300 and the international gateway exchange 220 (S433).

After receiving the call setup response signal from the called terminal of the other station, the IP server 101 mixes the call between the calling terminal and the called terminal of the other station to connect the call (S435).

Figure 5 illustrates a procedure for a caller making an international call and storing the call in real time according to a preferred embodiment of the present invention.

As shown in FIG. 5, first, when a caller makes an international call to a user of another country, a feature code (eg, * 03) for storing real-time call contents in a terminal, an international call identification number, a called country code, and an incoming call The telephone number of the terminal is input and connected to the IP server 101 via the switch 200 (S501). The originating exchange 200 recognizes that the call is a call for accessing the international message call service system based on the international telephone identification number, and routes the originating terminal to the IP server 101.

The IP server 101 transmits a call setup request signal to the destination side exchange 320 of another station through the international switching network 300 according to the function code transmitted from the originating terminal (S503), and the destination side exchange 320 of the other station. Transmits the call setup request signal to the called terminal (S505).

Subsequently, the receiving side exchange 320 of another station receives a call setup response signal from the called terminal (S507), and transmits a call setup response signal to the IP server 101 through the international switching network 300 (S509).

The IP server 101 which receives the call setup response signal from the called party exchange 320 through the international switching network 300 forms a call path between the calling terminal and the called terminal of another station by answering the call to the calling terminal (S511). ).

The IP server 101 stores the contents of the call coming and going between the calling terminal and the called terminal of another country through the formed call path (S513). The stored call contents are transmitted to the database server 107 and stored (S515).

Thereafter, after the call between the calling terminal and the called terminal is terminated, the IP server 101 calculates the call recording history (for example, the recording time) and transmits it to the billing recording device 111 together with the caller information ( S517). The billing recorder 111 stores the caller information and the call recording details correspondingly.

Then, the billing recording device 111 transmits the call recording history together with the caller information to the billing processing device 113 (S519), and the billing processing device 113 transmits the call recording history transmitted from the billing recording device 111. The bill is calculated and billed by the sender based on the monthly fee for each subscriber stored inside (S521). That is, the billing processing unit 113 subtracts the monthly fee (or the number of available cases) according to the caller's call recording time (or the number of call recordings), and if the limit is exceeded, the excess time (or number) The additional bill will be charged as. At this time, if the call recording time (or the number of call recordings) for a month does not exceed the monthly fee (or the number of available calls), the billing processing unit 113 may determine the remaining monthly fee (or the number of available calls). Carry over to next month.

6 illustrates a procedure of recording and transmitting a voice message when the called party is in a state of incapable of communication when attempting an international call according to an exemplary embodiment of the present invention.

As shown in FIG. 6, when a caller first attempts to make an international call by inputting an international telephone identification number, a called country code, and a phone number of a called terminal, the calling terminal accesses the IP server 101 (S601). . Then, the IP server 101 transmits a call setup request signal to an exchange of another station through the international exchange network 300 (S603).

At this time, when the called terminal is in a state where it is impossible to make a call, for example, when the power is off, during a call, or when the call right is released, the exchange of another station transmits a call setup response signal including the call unavailable state information of the called terminal to the international exchange network 300 In step S605, the IP server 101 transmits to the IP server 101.

The IP server 101 transmits a call connection response signal indicating a call unavailable state of the called terminal to the calling terminal through the calling side switch 200 (S607). Subsequently, when the caller inputs a DTMF shortcut for recording a voice message, the calling terminal transmits the DTMF shortcut signal to the IP server 101 through the calling side switch 200 (S609).

The IP server 101 transmits a recording guidance message to the calling terminal according to the DTMF shortcut key signal (S611). For example, "KTF international message call. Record after the beep and press the well sperm when finished. For example, beep."

Subsequently, the calling terminal receives the voice from the user and transmits the voice to the IP server 101, and the IP server 101 records the transmitted voice (S613). At this time, the IP server 101 may transmit a recording completion guide message to the calling terminal after the recording is finished.

The IP server 101 transmits and stores the recorded voice message and the information of the recorded voice message to the database server 107 (S615). Here, the information of the recorded voice message includes the calling terminal phone number, called country code, called terminal phone number, voice recording time, and the like.

Subsequently, the IP server 101 transmits a guide message for the reservation transmission to the calling terminal and receives a response thereto (S617). For example, "Please press 1 for instant delivery and 2 for reservation". When the caller selects a reservation transmission, the IP server 101 receives a response by transmitting a guide message for setting a reservation time to the calling terminal. Subsequently, the IP server 101 releases the call with the calling terminal (S619).

As such, when the caller leaves a voice message due to the caller's inability to call, the IP server 101 transmits the caller's voice message recording time information to the charging recording device 111 (S621). The billing recording device 111 stores the voice message recording time information received from the IP server 101 in correspondence with the caller's phone number, and stores the caller's phone number and the caller's voice message recording time information in the billing processing device 113. Transfer to (S623). At this time, the billing recording device 111 aggregates the voice message service usage history of the subscriber on a monthly basis and transmits it to the billing processing device 113, or the billing processing device 113 whenever the subscriber uses the voice message service. Can be sent to. This can be selected according to the service type.

The billing processing unit 113 calculates the caller's fee with reference to the monthly fee information for each subscriber stored therein and the information received from the billing recording device 111 (S625). That is, the monthly fee is subtracted according to the caller's voice message usage time, and the additional bill is charged for the rate exceeding the limit (or the number of voice message usage). The remaining monthly fee is then carried over to the next month.

On the other hand, if the sender selects the transmission immediately in step S617, IP server 101 transmits the outbound call setup request signal to the international gateway switch 220 that is connected to E1 or T1 (S627), the international gateway switch ( 220 transmits the call connection request signal to the destination terminal via the international exchange network 300 and the destination side exchange 320 of another station according to the outbound call setup request signal of the IP server 101 (S629).

Subsequently, the international gateway switch 220 that has received the call connection response signal from the destination terminal via the international switching network 300 and the destination side exchange 320 of another station (S631) sends an outbound call setup response signal to the IP server 101. It is transmitted (S633). As a result, a call path is formed between the IP server 101 and the destination terminal of another station.

The IP server 101 loads the voice message recorded by the caller stored in the database server 107 and reproduces the voice message to the called terminal through the formed call path (S635).

After reproducing all the voice messages, the IP server 101 transmits a call termination signal to the international gateway exchange 220, and the international gateway exchange 220 receives the terminal through the international exchange network and the destination exchange 320 of another country. The call termination signal is transmitted to release the call between the IP server 101 and the called terminal (S637).

On the other hand, when the caller selects the reserved transmission in step S617, the APS 103 for scheduling the voice message transmission requests the IP server 101 to the IP server 101 upon arrival of the reserved transmission time set by the sender. The IP server 101 performs the above steps S627 to S637.

After the call between the IP server 101 and the destination terminal of the other station is released, the IP server 101 notifies the APS 103 of the completion of the voice message transmission, and the APS 103 receiving the notification completes the voice message transmission. A message may be created and transmitted to the calling terminal through the SMSC 260.

7 is a flowchart illustrating a procedure for making a reservation call when a called party is in a state of incapable of communication when attempting an international call according to an embodiment of the present invention.

Here, when the caller attempts to make an international call through the international message call service system, the process of inputting a DTMF shortcut key when the called party is in a call disabled state (S701) is the same as that of steps S601 to S609 of FIG. 6, and thus a detailed description thereof will be omitted. .

Next, as shown in FIG. 7, the IP server 101 transmits a call reservation setting guide message to the calling terminal according to the DTMF shortcut key signal (S703). For example, "KTF is an international message call. After 1 hour, press 1 for reservation settings and 2 for specific time reservations."

Subsequently, the calling terminal receives the call reservation time from the user and transmits the call reservation time to the IP server 101 (S705), and the IP server 101 stores the call reservation information in the database server 107 (S707). In this case, the IP server 101 may transmit a setting completion guide message to the calling terminal after the reservation setting is completed. Here, the call reservation information includes the calling terminal phone number, called country code, called terminal phone number, call reservation time (including date), and the like.

Subsequently, the IP server 101 transmits a call release signal to the calling terminal through the calling side switch 200 to release the call with the calling terminal (S709), and sends the caller information and the corresponding caller to the charging recording device 111. The international telephone reservation of the fact is transmitted (S711). The accounting recording device 111 correspondingly stores caller information transmitted from the IP server 101 and the fact that the caller has made an international call reservation. Then, the billing recording device 111 transmits the caller's international call reservation service usage history to the billing processing device 113 (S713). Transmission of the service usage history may be collectively transmitted on a monthly basis, or may be immediately transmitted whenever the subscriber uses the service. This can be selected according to the service policy. The billing processing unit 113 calculates the caller's fee by referring to the monthly fee information per subscriber, that is, the number of reservation service available and the usage history received from the billing recording device 111 (S715). The number of monthly flat-rates will be subtracted by the number of caller's reservations, and if the limit is exceeded, additional charges will be made according to the billing policy for each service. Otherwise, if the number of reservation service usage is within the monthly limit, the remaining available number is carried over to the next month for reuse.

Thereafter, the APS 103 in charge of scheduling makes a call connection request to the IP server 101 according to the call reservation time stored in the database server 107 (S717). At this time, the call connection request signal includes a calling terminal telephone number, a called country code, a called terminal telephone number, and the like.

First, the IP server 101 transmits a call setup request signal to the calling terminal through the calling side switch 200 according to the call connection request of the APS 103 (S719), and at the call response of the calling terminal (S721), A guide message confirming whether or not to make a reservation call is transmitted to the calling terminal (S723).

When the caller accepts the reserved call (S725), the IP server 101 transmits the ring back tone to the calling terminal (S727), and then, through the international gateway exchange 220 and the international exchange network 300, the destination exchanger of another country ( In step S729, a call setup request signal is transmitted.

The destination exchange 320 of another station transmits a call setup request signal to the destination terminal and receives a response signal thereto (S731). The destination exchange 320 of another station transmits a call setup response signal to the IP server 101 via the international exchange network 300 and the international gateway exchange 220 (S733).

After receiving the call setup response signal from the called terminal of the other station, the IP server 101 mixes the call between the calling terminal and the called terminal of the other station and connects the call (S735).

8 illustrates a procedure of real-time storing of call contents at the request of a user during an international telephone call according to an exemplary embodiment of the present invention.

As shown in FIG. 8, first, when a caller attempts to make a call by inputting an international telephone identification number, a called country code, and a telephone number of a called terminal into an calling terminal for an international call with a user of another country, the calling terminal makes a call. It connects to the IP server 101 via the side exchange 200 (S801). At this time, the calling side exchange 200 recognizes that the call is a call for accessing the international message call service system based on the international telephone identification number included in the call signal of the calling terminal, and refers to the calling terminal by referring to the home location register 250. To IP server 101.

Next, the IP server 101 transmits a call setup request signal to the destination side exchange 320 of another station through the international gateway exchange 220 and the international exchange network 300 (S803), and the destination side exchange 320 of the other station. ) Transmits a call setup request signal to the called terminal (S805).

Subsequently, the receiving side exchange 320 of another station receives the call establishment response signal from the called terminal (S807), and transmits the call establishment response signal to the IP server 101 through the international switching network (S809).

The IP server 101 transmits a call setup response signal to the originating terminal via the originating exchange 200 to form a call path between the originating terminal and the called terminal of another station (S811).

When a caller enters a DTMF shortcut key for storing real-time call contents during a call between a caller and a foreign party, the caller terminal transmits a DTMF signal to the IP server 101 (S813). Thereafter, the IP server 101 stores the call contents (S815). The stored call details are transmitted to the database server 107 (S817).

After the caller and the called party ends, the IP server 101 calculates the call recording history (for example, the recording time) and transmits the call recording information to the billing recording device 111 together with the caller information (S819). The billing recorder 111 stores the caller information and the call recording details correspondingly.

Then, the billing recording device 111 transmits the call recording history together with the caller information to the billing processing device 113 (S821), and the billing processing device 113 transmits the call recording history transmitted from the billing recording device 111. And the billing of the sender's charges based on the monthly fee per subscriber stored in the inside and bills (S823). That is, the billing processing unit 113 subtracts the monthly fee (or the number of available cases) according to the caller's call recording time (or the number of call recordings), and if the limit is exceeded, the excess time (or number) The additional bill will be charged as. At this time, if the call recording time (or the number of call recordings) for a month does not exceed the monthly fee (or the number of available calls), the billing processing unit 113 may determine the remaining monthly fee (or the number of available calls). Carry over to next month.

9 is a signal flow diagram illustrating an international message call service method using an internet network according to a preferred embodiment of the present invention, wherein the international message call service system receives and stores a voice message from a calling terminal and stores the voice message on the Internet. When the international message call service system of another country is transmitted through a network, an international message call service system of another country processes an outbound call directly to a called terminal to deliver a voice message.

At this time, as a pre-step of the procedure shown in FIG. 9, the procedure in which the caller connects to the international message call service system to record and charge the voice message is illustrated in steps S301 to S319 of FIG. 3. , The calling subscriber enters the feature code (e.g., * 01), the international telephone identification number, the called country code, and the telephone number of the called terminal into the calling terminal to access the international message call service system and records the voice message. The voice recording service may be charged.

Alternatively, the process in which the calling subscriber accesses the international message call service system to record a voice message and charge processing is performed when the caller attempts to make an international call using the international message call service system shown in steps S601 to S625 of FIG. 6. In other words, the caller terminal of another country is in a state of being incapable of communication, thereby inputting a DTMF hotkey to record a voice message in the international message call service system, and may charge the voice recording service.

The process of transmitting the recorded voice message to the called party's terminal in another country through the Internet network will be described with reference to FIG.

When the caller selects the immediate transmission of the voice message, the IP server 101 transmits the recorded voice message to the international message call service system 400 installed in another station through the TCP / IP-based internet network (S901).

The international message call service system 400 of another station transmits an outbound call setup request signal to the called side exchange 320 (S903), and the called side exchange 320 transmits a call setup request signal to the called terminal (S905). ).

Subsequently, the called side exchange 320 receives a call setup response signal from the called terminal (S907), and transmits an outbound call setup response signal to the international message call service system 400 of another station (S909). As a result, a call path is formed between the international message call service system 400 of the other country and the called terminal.

The international message call service system 400 of another country reproduces the voice message transmitted through the Internet network to the called terminal (S911).

On the other hand, when the caller selects the scheduled transmission, the APS 103 for scheduling the voice message transmission requests the IP server 101 to the IP server 101 when the scheduled transmission time arrives set by the sender. The IP server 101 performs the step S901, and then the steps S903 to S911 are performed.

In addition, in the procedure shown in Fig. 9, an international message call service system 400 installed in another country transmits a received notification SMS message including a callback number to a called party terminal and the called party sends a call to the callback number. You can also try to listen to the voice message.

10 is a signal flow diagram illustrating a procedure for converting a text message created by a caller into a voice message and transmitting the same to a called party in another station in a wired / wireless Internet environment according to a preferred embodiment of the present invention.

As shown in FIG. 10, the caller accesses and logs in to the web server 109 via the wired / wireless Internet as a terminal (S1001). The web server 109 displays the screen for the international message call service to the caller's terminal (S1003). The screen for the international message call service provides a menu for text message transmission and a menu for voice message transmission.

After the sender selects the text message transmission, the caller enters the caller's phone number, the country code of the other country, the recipient's phone number of the other country, and the text message to be delivered to the destination of the other country (S1005). At this point, the sender may choose to send the text message immediately, or to send the scheduled message.

Subsequently, the web server 109 works in conjunction with the TTS server 105 to convert the text message input by the caller into a voice message (S1007), and converts the converted voice message and the information of the voice message (caller's phone number, other station's information). Country code, called party's telephone number of another country, transmission time, etc.) is stored in the database server 107 (S1009). Although not shown in the drawing, the web server 109 transmits caller information and voice message usage history to the billing recorder 111, and the billing recorder 111 stores the caller information and voice message usage history in correspondence. do. The billing recording device 111 transmits caller information and a voice message usage history to the billing processing device 113 every month or every time a voice message is used. Then, the billing processing device 113 calculates the caller's fee based on the subscriber's monthly fee information. That is, depending on the caller's voice message usage time (or the number of voice message usage), the monthly fee (or the number of monthly subscriptions available) is subtracted, and the charges exceeding the limit (or the number of voice message usage) are charged. The bill is additionally settled according to the policy. Meanwhile, the remaining monthly fee (or the number of monthly subscriptions available) is carried forward to the next month.

Meanwhile, the web server 109 makes a voice message transmission request to the APS 103 which schedules the voice message transmission (S1011), and the APS 103 makes a voice message transmission request to the IP server 101 (S1013). . At this time, the APS 103 schedules the voice message transmission based on the information of the voice message stored in the database.

Subsequently, the IP server 101 transmits an outbound call setup request signal to the international gateway exchange 220 (S1015), and the international gateway exchange 220 exchanges the destination side exchange 320 of another country via the international exchange network 300. The call connection request signal is transmitted through the call (S1017).

The called party exchange 320 of another station transmits a call connection request signal to the called party terminal (S1019), and in response, receives a call connection response signal from the called party terminal (S1021).

Subsequently, the destination side exchange 320 of another country transmits a call connection response signal to the international gateway exchange 220 through the international exchange network 300 (S1023), and the international gateway exchange 220 goes out to the IP server 101. The bound call setup response signal is transmitted (S1025). As a result, a call path is formed between the IP server 101 and the called party's terminal in another country.

The IP server 101 loads the recorded voice message stored in the database server 107 and reproduces the voice message to the called terminal through the formed call path (S1027).

After reproducing the voice message, the IP server 101 transmits a call termination signal to the international gateway exchange 220, and the international gateway exchange 220 passes the call to the called terminal via the international exchange network 300 and the exchange of another country. The call is released between the IP server 101 and the called terminal by sending an end signal (S1029).

After the call between the IP server 101 and the destination terminal of the other station is released, the IP server 101 notifies the APS 103 of the completion of the voice message transmission, and the APS 103 receiving the notification completes the voice message transmission. A message may be created and transmitted to the calling terminal through the SMSC 260.

Meanwhile, FIG. 10 illustrates a method of converting a text message created by a caller into a voice message and transmitting the message to a recipient of another country in a wired / wireless Internet environment. However, the caller immediately accesses the web server 109 through the wired / wireless Internet. The voice message can be recorded and transmitted to the called party's terminal. To this end, the web server 109 stores the voice message recorded by the caller and information of the voice message (caller's phone number, country code of another country, caller's phone number of another country, transmission time, etc.) in the database server 107. Thereafter, the APS 103 may be requested to transmit a voice message, and the steps S1011 to S1029 may be performed.

In addition, although FIG. 10 illustrates a process of transmitting a voice message to a receiver terminal of another country through the international exchange network 300, the voice message may be transmitted to a receiver terminal of another country through the Internet network. The process of transmitting the voice message to the called party's terminal in the other country through the Internet network is the same as the steps S901 to S911 shown in FIG.

In addition, when a caller composes and transmits a text message in a wireless communication terminal, the international message call service system may convert the text message into a voice message and transmit the text message to a called party terminal in another country through an international switching network or an internet network. To this end, the caller creates a text message and transmits it by inputting a predetermined function code (which indicates the conversion of the text message to voice), an international telephone identification number, a called country code, and a called terminal number. The transmitted text message is transmitted to the IP server 101 via the SMSC 260, and the IP server 101 converts the text message into a voice message in association with the TTS server 105 and stores it in the database server 107. . The IP server 101 transmits the converted voice message to the called party's terminal in another country through the international exchange network or the Internet network.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.
