Description
METHOD AND APPARATUS FOR PROVIDING VARIOUS ADDITIONAL SERVICE IN THE INTERNATIONAL COMMUNICATION NETWORK
Technical Field
[1] The present invention relates to a method and apparatus for sending voice messages and providing various supplementary services using an international communication network.
Background Art
[2] In the case of existing international telephone service, voice call and text message service is mainly provided to communication service customers using a telephone or wired/wireless network. In the case of different countries, there are time differences between the countries, therefore, also in the case of international calls, there are many cases where calling customers do not send messages at an appropriate time or send simplified messages due to factors such as the time difference and the high cost.
Furthermore, even in text messages, there is a disadvantage in that messages have to be written in English because the types of terminals used and the languages supported in respective countries are different. Even in the case of overseas roaming phones, if a user sends a Korean message to an overseas customer roaming from Korea to a foreign country, the message is sent to the called party in a form in which the pronunciation thereof is represented in English, that is, phonetically, because the message cannot be written in Korean. Accordingly, the user's intention is not communicated to a customer who does not know English or cannot read English phonetically.
[3] Furthermore, even in the case of prepaid/postpaid card service, which is used
frequently during overseas travel, only simple voice calls are supported, but supplementary services for international call service are not provided. In addition, in existing international call service, in the case where a call is not connected with a called party during a call attempt or in the case of a time difference, service for making a scheduled international call using a wired/wireless telephone terminal or the wired/ wireless Internet has not been provided. Furthermore, a service function of recording the content of business-related communication with an important buyer during an overseas international call, the content of an important conversation between parents and siblings, etc. in real time and managing them has not been provided.
[4] In the case of an existing local/trunk/international call Prepaid/Postpaid System
(PPS) service provider, a PPS provides only a function of authenticating a calling customer and then dialing a called customer after the calling customer accesses PPS service, but does not provide services of recording a message and sending the recorded message to a counterpart while dialing or calling, scheduling a call, and supporting recording during a call. Furthermore, there is no method of providing service capable of sending a voice message or automatically scheduling a call using the wired/wireless Internet.
[5] The existing international call uses voice call-oriented real-time call service or overseas text service, but does not provide a method of recording and sending a voice message or a method of converting a text message into voice and then sending the voice to a called overseas party after the text message has been written. Furthermore, the existing international call does not provide a method in which a calling party directly records a voice and sends the voice message to an overseas counterpart using a Feature Code (FC)/a Service Access Code (SAC) or the web/wired Internet. In addition, in the case of existing international call service, counterpart country Voice Mail System (VMS) service is "called party-based service," and is a service that can be optionally used when a counterpart cannot make a call. In this service, a guidance announcement is made in the language of a corresponding country and fees are charged in the same manner as international call fees, therefore the use thereof is inconvenient and difficult. Furthermore, in the existing international call, in the case where an overseas text message is sent, or a calling party leaves a voice message in a counterpart country VMS, there is no method of determining whether a counterpart has received the text message left by the calling party or has listened to the voice message left in the VMS by the calling party. Furthermore, the existing international call does not provide a method for a calling party to send a voice message to a counterpart when a call with a called party is impossible during an attempt to establish a call with the called party. Furthermore, the existing international call does not have a function of automatically connecting a call to a counterpart several hours later when a call with the called party is impossible during an attempt to establish a call with the called party. Furthermore, the existing international call does not have a function of scheduling a call to a called overseas party at a specific time and then automatically connecting a calling party with a called party at a corresponding time using Interactive Voice Response (IVR), the web and the wireless Internet through an international communication network or an international value added communication network. Furthermore, the existing international call does not provide a method in which a calling party and a called party record the content of communication in real time and manage the recorded content of communication over a network by pressing the specific key (Dual Tone Multi
Frequency (DTMF) key) of a wired/wireless terminal during a call. The existing international call scheduling service does not provide a function of setting a Short Message Service (SMS) or an outbound call method for a calling party. Disclosure of Invention
Technical Problem
[6] To solve the above problems, an object of the present invention is to allow a local wired/wireless communication customer to record a voice message or convert a text message into voice, and send it to a called overseas party or a number of members belonging to a group immediately or at a scheduled time using the existing international telephone network or the Internet without using a general method, such as a voice call or an SMS message, when the local wired/wireless communication customer communicates with an overseas customer using a telephone terminal or the web/wired Internet.
[7] Another object of the present invention is to perform a function of sending a confirmation text message, indicating that a called overseas party has listened to a voice message sent by a local calling party, to the calling party when the called overseas party has listened to the voice message, and allowing the called party to leave a response message for the calling party after listening to the message, so that a reply can be sent to the calling party immediately or at a scheduled time.
[8] A further object of the present invention is to perform a function in which a calling party, through a service providing apparatus, records a voice message and sends the voice message to a counterpart, or selects one hour, two hours, etc. and then an international call is automatically connected after the selected time using an automatic call scheduled function, when the calling party attempts a call to a called overseas party but fails for a reason such as Busy, No Answer, Out of Range or Power Off.

Advantageous Effects
[69] The present invention provides international call voice message service in which a voice message (memo) is left simply and conveniently and is then sent to an overseas counterpart when sending simple greetings, simple news, an anniversary day (a birthday, etc.) message or a business report to a counterpart without using a direct international call or an overseas text service in communication with an overseas friend, a relative, a co-worker, or a business client. That is, when attempting a call with an overseas counterpart, a voice can be left and sent to the counterpart without making a call using an FC or an SAC, or a voice message can be easily sent to a called overseas customer using the wired/wireless Internet, either immediately or at a scheduled time. Furthermore, the voice message can be sent to a plurality of called parties at the same time. If the international call message transmission system is used, a message including a user's voice can be sent to a called overseas customer even in the case where there is a time difference or a call is not made. Accordingly, there is an advantage in that a called party can have feelings of closeness, intimacy, nostalgia for a mother country, etc. Furthermore, in the case where a telephone call with overseas foreigners is difficult due to conversational or language barriers, if a text message, which will be sent to a counterpart, is written in Korean, the Korean language is changed (for example, in the case where the Korean language is translated into the Chinese language, the Korean language is translated into the Chinese language using an LTS), converted into voice (for example, converted into a Chinese voice message), and then sent to an overseas customer, using the service of the present invention, there is an advantage in that the called party can understand the content easily while listening to the message received from the calling party. Furthermore, the present invention can be used by adding voice message transmission service, local/long-distance/automatic international call scheduling service, international call recording service, etc., as well as a voice call to the PPS service, that is, the existing prepaid/postpaid card service. This enables communication service providers to make profits through various supplementary services of the present invention, and enables customers to use the service of the present invention as well as make voice calls. Accordingly, there is an advantage in that various customers are accommodated.
[70] Furthermore, the present invention provides a service function of simply scheduling a call when a subsequent call is desired (simple call scheduling), and scheduling a specific time and automatically making an international call when the specific time has been reached (specific time scheduling) in the case where a direct international call is impossible due to the time difference between countries or when a call with a counterpart is impossible while attempting an international telephone call with overseas friends, relatives, co-workers, or business clients. The present service is advantageous in that, in the case where a wired/wireless telephone terminal is used, a calling party can be provided with simple scheduling service using a DTMF shortcut key when a counterpart does not answer a call during call connection to a called overseas party, and can schedule a specific time using an FC. Furthermore, the calling party can be provided with simple scheduling or specific time scheduling service so as to make an international call with a called overseas customer using the wired/wireless Internet. In the case where a calling customer uses the present service, a method of informing the calling party that the scheduled time has been reached is realized through a selection function of directly setting and managing an SMS message method and an outbound call method through the service providing apparatus. If a customer uses the automatic international call scheduling service as described above, there is an effect in which an important international telephone call with a called party can be effectively made at a time desired by a calling customer regardless of a time difference.
[71] Furthermore, according to the present invention, in a telephone call with overseas friends, relatives, co-workers or business clients, in the case where it is desired to save the content of communication with a counterpart, or the content of business-related communication is desired to be recorded and heard again, international call recording service can be used. In the case where a call is not frequently made between overseas parents/children, lovers, a married couple, etc. due to expensive international calling fees, a communication history can be recorded and managed using an album. Thus, when wanting to hear the communication history anytime, or when intentions are not accurately transferred during a call due to the language barrier at the time of a call between clients or businesses, the service of recording communication content can be used at the time of making an international call. The international call recording service provides a selection function in which a function of recording a call from the beginning or from a specific part can be set in the service providing apparatus. Furthermore, a message recorded while making an international call can be managed (repeatedly listened to, deleted, etc.) through the wired/wireless Internet, therefore a calling customer can manage the content of communication anytime.
[72] In the overseas text service (overseas SMS service), the terminals and languages supported in different countries are different, therefore, when a calling party sends a message written in Korean, the message is transmitted such that a called party cannot understand the message or the Korean language is phonetically converted into English characters (that is, when the sentence in Korean corresponding to"I love you"is sent to a foreign country, the text is converted into "Saranghae(corresponding to "I love you" in Korean)" in English). Thus, foreigners cannot understand the meaning of
"Saranghae". In contrast, the use of the present invention is advantageous in that a calling party's intention can be accurately communicated to a counterpart in such a manner that the text is written in Korean, translated into a counterpart language using the LTS, and converted into a voice message using the TTS.
[73] According to the present invention, wired/wireless customers who do not want to make an international call because of the expensive international call fees or the time difference, or who are not good at using international SMS service can utilize the present invention to send voice messages easily without calling a called overseas party.
[74] According to the present invention, voice message transmission service, local/ long-distance/automatic international call scheduling service, international call recording service, and so on, as well as a voice call can be added to the PPS, that is, the existing prepaid/postpaid card service. This enables communication service providers to make profits through various supplementary services of the present invention, and enables customers to use the service of the present invention as well as to make voice calls. Accordingly, there is an advantage in that various kinds of customers can be accommodated.
[75] The present invention can be utilized to send congratulatory voice messages on special days. That is, a user may send a counterpart a voice message with musical content inserted therein as a congratulatory gesture or on specific special days
(birthday, anniversary, Christmas, Valentine's Day, etc.).
[76] According to the present invention, a voice message can be easily sent to a called party using a voice call to express sentiments, love, etc.
[77] According to the present invention, a calling party can set a nickname, therefore, when a counterpart receives a message, he can listen to the nickname of the calling party.
[78] According to the present invention, in the case where content is to be sent to a
number of persons who are abroad on business, a voice message can be sent to a number of overseas customers at the same time using a group directory, either im- mediately or at a scheduled time.
[79] According to the present invention, a user's own recorded voice message can be sent, either immediately or at a scheduled time, as desired.
[80] According to the present invention, in the case of call impossibility (No Answer/
Busy/Power Off/Out of Range) with a counterpart upon an attempt to make an international call, a call can be automatically scheduled, and a voice memo can be recorded and sent.
[81] According to the present invention, a message can be recorded and sent to a called party in a different country using the wired/wireless Internet as well as a wired/wireless terminal.
[82] Furthermore, according to the present invention, in the case where the apparatus of the present invention or a similar apparatus is installed abroad and apparatuses are operated at home and abroad, a message, which is recorded and sent by a calling party over the Internet, can be transferred to an overseas customer cheaply without incurring addition network cost through a mutual network interworking function. Accordingly, there is an advantage in that communication service providers can make profits.
[83] The present invention allows a subscription-type service and a non-subscription-type service to be utilized depending on the billing policy of a service provider.
[84] The present invention provides international call scheduling service, in which a call time with an international called party is scheduled using a wired/wireless telephone terminal or the wired/wireless Internet, a calling party is automatically informed that a corresponding time has been reached via an SMS message, an outbound call, etc., and the international call is automatically connected. This service can be used a lot when it is difficult to make international calls with overseas customers due to the time difference between countries.
[85] The present invention can provide an international call recording service function that is used to record the content of communication with a counterpart in real time depending on the importance of the content of communication at the time of an international call.

Best Mode for Carrying Out the Invention
[107] Preferred embodiments of the present invention will be described in detail in
conjunction with the accompanying drawings.
[108] FIG. 1 is a diagram illustrating the internal construction of an apparatus for
providing various supplementary services using an international communication network according to a preferred embodiment of the present invention.
[109] Referring to FIG. 1, mobile communication terminals 101 refer to terminals for performing voice and data communication over a GSM/CDMA mobile communication network, and terminals through which calling parties and called parties perform voice and data communication in a service providing apparatus 111. Wired terminals 103 are terminals for voice and data communication over a Public Switched Telephone
Network (PSTN).
[110] The PSTN refers to a wired communication network exchange. A Mobile Switching
Center (MSC) refers to a wireless communication network switching device, and functions to route the call of a subscriber who makes a telephone call to the present service providing apparatus. An El/Tl processing apparatus is connected to the switching apparatus via physical El/Tl, and performs voice and signal processing in conjunction with the switching apparatus. The signal processing apparatus processes call processing signals, such as R2, PRI and SS7, received by the El/Tl processing apparatus, and sends the call processing signals to the switching apparatus through the El/Tl processing apparatus.
[I l l] An Intelligent Peripheral (IP) Server 113 is an IP apparatus for performing voice message call processing and voice recording/transmission through the wired/wireless telephone terminals 101 and 103 in conjunction with the PSTN or MSC via El/Tl.
[112] A Prepaid/Postpaid System (PPS) server 115 is an apparatus for providing a prepaid card or postpaid card service function through the wired/wireless telephone terminals 101 and 103 in conjunction with the PSTN or MSC via El/Tl.
[113] An Audio Response System (ARS) server 106 is an apparatus for recording, storing and sending voice messages according to an IVR guidance announcement via an ARS representative number access number, for example, 060-700-1234 or 010-2000-1234, through the wired/wireless telephone terminals 101 and 103 using SS7, PRI or R2 signaling in conjunction with the PSTN or MSC via El/Tl Trunk.
[114] A Web/WAP (ME) Application Server (WWAS) 127 is an apparatus capable of processing directory management necessary for voice message transfer, and history management for message transmission, etc. through the web or the wireless Internet.
[115] A Database Server (DBS) 121 is an apparatus for storing and managing data related to the service providing apparatus, such as calling subscriber information, voice message information, called party information, and statistics.
[116] An Application Plus Server (APS) 125 performs SMS transmission, billing,
subscriber registration /authentication, prepaid subscriber authentication and subscriber number transfer processing functions in conjunction with a Short Message Service Center (SMSC) 137, a Billing System (BS) 135, a Customer Care System (CS) 133, a Number Portability Data Base (NPDP) (not shown), an intelligent Service Control Point (SCP) system (not shown), etc., which are managed by a service provider for the present service. The SCP is an apparatus having service logic for automatic scheduled call processing using an intelligent network, which is a service provider apparatus for processing automatic scheduled calls in conjunction with the APS 125.
[117] The Customer Care System(CS) 133 is a communication service provider customer database, which is an apparatus for processing functions such as subscriber authentication and PPS customer authentication. The Billing server(BS) 135 is an apparatus for processing billing for the service providing apparatus 111, or processing functions such as charging/deduction and customer balance inquiry at the time of PPS service.
[118] A TTS(Text To Speech) server 129 is an apparatus for converting a written text message into a voice message through the web or wireless Internet. A Language Translation Server (LTS) 131 is a server for translating a specific language into another language. An Operation Administration and Management Server (OMS, OA& M Server) 117 is an apparatus for operating/managing the service providing apparatus 111.
[119] The service providing apparatus 111 performs a function of leaving a voice memo simply and conveniently and sending the voice memo to an overseas counterpart when sending a simple greeting, simple news, a business report or the like to a counterpart without directly using an international call or overseas text service in communication with an overseas friend, a relative, a co-worker, or a business client. The service providing apparatus 111 provides a method of using "SAC or FC + a country code + a called overseas party telephone number" in such a manner that a message is recorded and sent to an overseas recipient, a method of recording/sending voice using the web or wireless Internet, and a method of writing a message, converting the message into a voice message using the TTS and sending the voice message using the web or wireless Internet, and the like. The service providing apparatus 111 provides a function of translating Korean into the language (text) of a corresponding country using the LTS 131, converting the language (text) into the voice message of a corresponding country through the TTS (129) engine of a corresponding country and then sending the voice message to a counterpart when it is desired to write a Korean text message and send a voice message translated into the language of a called overseas party using the web or wireless Internet.
[120] Furthermore, in the case where it is difficult or hard to a make a call due to the time difference between countries, the service providing apparatus 111 performs a scheduled call service function of setting a scheduled time for an international call in advance using the IP of the service providing apparatus 111 and the web or wireless Internet, automatically informing a calling party of the fact that the corresponding time has been reached, and automatically connecting a call to a called overseas party. In the case where a calling party desires to record the important content of communication during a call with a called overseas party, the service providing apparatus 111 also performs a function of detecting DTMF tones and then recording the content of the call between the calling party and the called party in real time when a calling party presses a specific DTMF key.
[121] A method of sending text and voice messages to a called party via voice through an international exchange network or the Internet in the wired/wireless communication network of the present invention can be classified into subscription-type service and non-subscription-type (general) service. The subscription-type service is a method of subscribing to the service through the wired/wireless Internet, an IVR apparatus, a customer center, an agent, etc., and then using the service of the present invention. The non-subscription-type service (general) service is characterized in that any service provider can use the service of the present invention without requiring an additional service subscription procedure. The service providing apparatus 111 is an apparatus capable of providing both the subscription-type service and the non-subscription-type service. The subscription-type service will be described in detail in conjunction with FIGS. 2 to 8. The procedures described in conjunction with FIGS. 9 to 21 can be applied both to the subscription-type service and to the non-subscription-type service.
[122] Furthermore, in the case where the PPS card of a communication service provider is purchased and the service of the present invention is used, fees are deducted from the PPS card according to the amount of service used on the basis of a purchased PPS card number. Accordingly, the provision of the subscription-type service-based service using the wired/wireless telephone terminals 101 and 103 is fundamental, and, in the case where the wired/wireless Internet is used, non-subscription-type service may be used.
[123] FIG. 2 is a view illustrating a procedure of storing a voice message for international voice message transmission service when a call is impossible during call connection in the subscription-type service according to a preferred embodiment of the present invention. This drawing illustrates a service procedure in which, in the case where a call with a counterpart is impossible for reasons of "Busy/Power Off/Out of Range or No Answer", or there is no answer from a called party when a customer who has subscribed to the service of the present invention (subscription-type service) attempts an international call, a calling party presses a DTMF shortcut key, records a voice message instead of making a direct call with the called party (an overseas customer), and sends the message, either immediately or at a scheduled time. A method for signaling interworking with the PSTN or MSC, that is, the wired/wireless communication service provider switching apparatus, will be described on the basis of SS7.
[124] Referring to FIG. 2, a calling terminal, that is, a calling subscriber, dials a called terminal, that is, a called overseas party, at step 201. In this case, a general wired/ wireless communication customer attempts a call to the called terminal by dialing, for example, "00ABC (or 00X, etc.) + country code + area code + called party telephone number," and a PPS customer attempts a call to the called terminal by dialing, for example, "PPS card access number + language selection + card number + *(#) + country code + area code + called party telephone number."
[125] The calling MSC sends an OrglnfoReq signal to the HLR in order to request the
HLR to determine whether the calling party customer is a subscriber who has subscribed to the service of the present invention at step 203. The HLR sends customer information about whether the customer has subscribed to the service of the present invention and routing information to the calling MSC with the information carried on an OrglnfoResp signal at step 205.
[126] The calling MSC sends an Initial Address Message (IAM) in order to route a call to the IP server using the routing information included in the received OrglnfoResp signal at step 207. The IP server or the PPS server receives the IAM from the calling MSC, and sends the IAM to an overseas communication service provider MSC in order to request called party call setup through the calling MSC and the international gateway exchange using a called number at steps 209 and 211. The overseas communication service provider MSC receives the IAM, and calls the called terminal. At this time, the state of the called overseas terminal is a reception impossible state, such as "Power Off/Busy/Out of Range", or a No- Answer state.
[127] The called overseas MSC responds to the call setup request by sending an Address
Complete Message (ACM) to the calling MSC at step 213. The calling MSC sends the ACM, received from the called overseas MSC, to the IP server (or the PPS server) at step 215. The IP server (or the PPS server) sends the ACM back to the calling MSC in response to the call setup request of the calling subscriber at step 217.
[128] After sending the ACM, the called overseas MSC sends a guidance announcement stating that the called subscriber is in the reception impossible state at step 219. In the case of No Answer, the calling party listens to a ring back tone. The guidance announcement or the ring back tone transmitted from the called MSC is transferred to the calling subscriber through the IP server. If the called overseas MSC cannot send the guidance announcement, for example, if there is no VMS, the called MSC does not send the ACM after receiving the IAM from the calling MSC, but can sent a call termination message (REL message) immediately. In this case, steps 213 to 219 may be omitted.
[129] The calling subscriber presses the DTMF shortcut key to use the service of the
service providing apparatus while receiving a Busy Tone (BT)/a Congestion Tone (CT)/a guidance announcement, or a ring back tone at step 221. The IP server (or the PPS server) receives/detects DTMF input by the calling customer, and sends the REL message to the calling MSC in order to terminate the call with the called overseas terminal at step 223. The calling MSC becomes aware that the REL message received from the IP server (or the PPS server) indicates the termination of the incoming call, and therefore sends the REL message to the called overseas MSC at step 225.
[130] The called overseas MSC terminates a corresponding call, and sends a call
termination completion signal RLC to the calling MSC in response thereto at step 227. The calling MSC sends the signal RLC, received from the called overseas MSC, to the IP server (or the PPS server) at step 229.
[131] After the overseas incoming call is terminated, the IP server (or the PPS server) sends a service guidance announcement, informing the calling subscriber of the service of the present invention, such as "Please press No. 1 for international call voice message transmission service, and No. 2 for international call automatic call scheduling service," at step 231. The calling customer presses a corresponding DTMF key in order to use the international call message transmission service at step 233.
[132] The IP server (or the PPS server) of the service providing apparatus analyzes
DTMF input by the calling party, determines whether the DTMF is used for the message transmission service, and controls the service at step 235. If, as a result of the determination, the DTMF is determined to be used for the message transmission service, the IP server (or the PPS server) performs step 237, and if, as a result of the determination, the DTMF is determined to be used for the international call scheduling service, the IP server (or the PPS server) performs step 245.
[133] The IP server (or the PPS server) of the service providing apparatus provides the calling party with a guidance announcement for the international call message service at step 237. An example of the guidance announcement may include "Please start recording after the 'beep' sound, and press # after recording. Beep." The calling customer records a voice message, which will be sent to the called customer, at step 239. At this time, if the calling customer has set a nickname through the WWAS (that is, the wired/wireless Internet access apparatus), the IP server (or the PPS server) provides an optional function of searching for a corresponding country using the country code of a called overseas party telephone number pressed by the calling party, changing the nickname of the calling customer to one in a corresponding country language through the LTS according to the corresponding country, and converting the language into voice for the corresponding country through the TTS server. The IP server stores the voice message, recorded by the calling customer, and the nickname of the calling party (changed into a corresponding country language), and send them to the called terminal.
[134] The IP server (or the PPS server) of the service providing apparatus provides a guidance announcement stating whether the calling party wants immediate
transmission or scheduled transmission at step 241. An example of the guidance announcement may include "Please press No. 1 for immediate transmission, and No. 2 for scheduled transmission." The calling customer inputs the time for immediate or scheduled transmission according to the voice guidance of the IP server of the service providing apparatus at step 243.
[135] At step 245, for the international call scheduling service, the IP server (or the PPS server) of the service providing apparatus sends a guidance announcement for the in- ternational call scheduling service, for example, "Please input scheduled time," to the calling terminal. The calling customer inputs a scheduled international call date and time and so on according to the voice guidance of the IP server (or the PPS server) of the service providing apparatus at step 247.
[136] Thereafter, the IP server (or the PPS server) of the service providing apparatus
sends information, received from the calling customer, to the APS at step 249. The APS of the service providing apparatus stores voice message information, scheduled international call data, and so on in the DBS at step 251.
[137] FIG. 3 is a view illustrating a procedure of transmitting a voice message, stored in a calling terminal, to a called overseas terminal according to a preferred embodiment of the present invention. The procedure described in conjunction with this drawing illustrates a procedure of a scheme in which message transmission performed through interworking between the service providing apparatuses or a similar interworking method. The protocol for the service providing apparatus includes a calling country, a called country, a calling number, a called party telephone number, a message serial number, a message size, a message format (voice/text), immediate/scheduled transmission information, transmission time, and so on.
[138] Referring to FIG. 3, the APS checks an interworking method (setting method), provided by the service providing apparatus for overseas interworking, to determine whether it is interworking with a Voice SMS (VSMS) system or with the existing international telephone network at step 301. The construction of the overseas VSMS system may include an IP server (or a PPS server), an APS, a DBS and an OMS server, and the names and functions of respective servers may be changed to each other. If, as a result of the determination, it is interworking with the VSMS system, the APS sends a voice message, recorded by the calling customer, to the overseas VSMS system through the Internet at step 303. At this time, the APS may send the voice message to the overseas VSMS system through, for example, FTP, etc.
[139] The overseas VSMS system stores the voice message received from the local APS, and determines whether it is a self-service provider network or some other service provider network in order to send the voice message to the called customer at step 305. That is, if setting is made such that the self-service provider network customer is informed of the reception of a message via an SMS message, the reception of the message can be sent to the self-service provider network customer via an SMS message. If setting is made such that the self-service provider network customer is informed of the reception of a message through an outbound call, the self-service provider network customer can be informed of the reception of the message through the outbound call. The SMS message notification method and the outbound call notification method may be set or changed through configuration. [140] If, as a result of the determination at step 305, setting is made such that the reception of a message is made known using the outbound call notification method, the VSMS system requests call setup from the called MSC at step 307. The called MSC requests call setup from the called customer. The called overseas customer responds to a received call, and listens to a received voice message through the VSMS system at step 309.
[141] If, as a result of the determination at step 305, setting is made such that the
reception of a message is made known using an SMS message notification method, the VSMS system sends an SMS message for providing notification of the reception of the voice message to the SMSC at step 311. The SMSC sends an SMS message, providing notification of the reception of the message, to the called customer at step 313. The SMS includes a call back number for accessing the VSMS system. The called party that has received the SMS accesses the VSMS system through the call back number, and listens to the received voice message at step 315. In this case, before listening to the received voice message, a process of customer authentication may be performed.
[142] After the called party has listened to the entire received message, the VSMS system sends a message, indicating that the message has been received and confirmed, to the APS at step 317. The APS requests the SMSC to send an SMS message in order to inform the calling terminal that the called overseas party has listened to the message at step 319. The SMSC sends an SMS message, indicating that the called party has listened to the message, to the calling terminal at step 321.
[143] FIG. 4 is a view illustrating a procedure of transmitting a voice message stored in a calling terminal to a called overseas terminal according to another preferred embodiment of the present invention. This drawing illustrates a procedure of transmitting a voice message of a calling party through an overseas communication service provider exchange network through interworking between heterogeneous apparatuses.
[144] Referring to FIG. 4, if the method of sending the message to the called customer is of an outbound call type at step 301 of FIG. 3, the APS requests called-side call setup from the calling-side MSC through the IP server (or the PPS server) in order to send the voice message, recorded by the calling customer, to the called overseas customer at step 401. The calling-side MSC requests call setup from an overseas international gateway exchange through the outbound call at step 403. The called-side MSC requests call setup from the called terminal at step 405.
[145] The called terminal sends a call response signal to the called-side MSC in response to the call setup request at step 407. The called-side MSC sends a response signal to the calling-side MSC at step 409. The calling-side MSC sends a response signal to the IP server (or the PPS server) of the service providing apparatus. The called terminal listens to the voice message, which has been received and stored, using a communication path connected to the IP server (or the PPS server) at step 411.
[146] The IP server (or the PPS server) of the service providing apparatus sends information, indicating that the called party has listened to the message, to the APS at step 413. The APS sends text information, indicating that the overseas recipient has listened to the message, to the calling-side SMSC at step 415. The SMSC sends a text message, indicating that the called party has listened to the message, to the calling customer so that the calling customer can become aware that the called party has received the calling customer's voice message and listened to the voice message at step 417.
[147] FIG. 5 is a view illustrating an international call scheduling service procedure
performed when a call is impossible during call connection based on the subscription- type service according to a preferred embodiment of the present invention.
[148] This drawing illustrates an international call scheduling service procedure in which, in the case where a call with a counterpart is impossible for reasons, such as Busy, Power Off, Out of Range or No Answer, or there is no answer from a called party while a customer who has subscribed to the service of the present invention (the subscription-type service) attempts an international call, the calling party schedules and sets the time for communication with the called party by pressing a DTMF shortcut key, the calling party is automatically informed of the international call scheduling information, and then a call is automatically connected when the scheduled time has been reached. A method of signaling interworking with the MSC, that is, the wireless communication service provider switching apparatus, is described on the basis of SS7.
[149] Referring to FIG. 5, the calling terminal sets the automatic call scheduling service according to the procedure described with reference to FIG. 2. The APS of the service providing apparatus queries the DBS about information scheduled by the calling party, and then periodically checks whether the scheduled time has been reached at step 501.
[150] If the scheduled time set by the calling customer has been reached, the APS checks a method of informing the calling party of the fact at step 503. The APS checks whether the calling party wants to provide notification of a scheduled international call time through the outbound call method or the SMS method. If the calling party wants to provide notification of a scheduled international call time using the SMS message method, the APS performs steps 505 and 507. In the case of the outbound call method, the APS performs steps 509 to 513.
[151] If the calling party has set the SMS method as the international call notification method at step 503, the APS sends information indicating that the scheduled international call time has been reached to the SMSC at step 505. The SMSC sends the message, received from the APS, to the calling customer via an SMS message, including the call back number, including a called party telephone number at step 507.
[152] If the calling party has set the outbound call method as the international call notification method at step 503, the APS of the service providing apparatus requests call setup from the IP server (or the PPS server) so that the IP server (or the PPS server) informs the calling party of the fact that the scheduled international call time has been reached at step 509. The IP server (or the PPS server) of the service providing apparatus requests call setup through the outbound call in order to inform the calling- side MSC of the scheduled international call time at step 511. The calling-side MSC sends a call setup request signal to the calling terminal in response to the call setup signal at step 513.
[153] The calling terminal (the customer who scheduled the international call) responds to an incoming call at step 515. For reference, in the case where the calling party has received the international call scheduling information via an SMS message, the call may be set through the existing international telephone network without passing through the service providing apparatus in such a manner that the calling terminal directly dials the called party.
[154] When the calling party responds, the service providing apparatus can inform the calling party of the international call scheduling information through voice at step 517. In this case, an example of the scheduling information may include "We will dial scheduled international call abcd-efgh."
[155] The IP server (or the PPS server) of the service providing apparatus requests called customer call setup from the calling-side MSC at step 519. The calling-side MSC requests call setup from the called-side overseas MSC at step 521. The called-side MSC requests call setup from the called customer at step 523. When the called customer responds, a call is made between the calling customer and the called overseas customer at step 525.
[156] FIG. 6 is a view illustrating the service procedure that is performed when there is no answer from a counterpart during call connection based on the subscription-type service according to a preferred embodiment of the present invention. This drawing illustrates a voice message transmission service and international call scheduling service procedure in which, in the case where there is no answer from a counterpart while a customer who has subscribed to the service of the present invention (the subscription- type service) attempts an international call, a calling party does not press a DTMF shortcut key and the service providing apparatus automatically detects no answer and provides the service of the service providing apparatus, unlike the procedures of FIGS. 2 to 5. A method of signaling interworking with the MSC, that is, the wireless communication service provider switching apparatus, is described on the basis of SS7.
[157] Referring to FIG. 6, the calling terminal attempts a call to the calling-side MSC in order to dial the called overseas terminal at step 601. In this case, a general wired/ wireless communication customer dials, for example, "00ABC + country code + area code + called party telephone number," and a PPS customer dials, for example, "PPS card access number + language selection + card number+ *(#) + country code + area code + called party telephone number."
[158] The calling MSC or the PSTN sends an OrglnfoReq message to the HLR in order to determine whether the calling party customer is a customer who has subscribed to the service providing apparatus service (for example, an international Plus Call) at step 603. The HLR sends customer subscription information about whether the calling party customer is a customer who has subscribed to the present service and routing information to the calling MSC using an OrglnfoResp signal at step 605.
[159] The calling MSC sends an IAM to the IP server (or the PPS server), that is, the service providing apparatus, in order to route the call using the received routing information at step 607. The IP server (or the PPS server), that is, the service providing apparatus, receives the IAM from the calling MSC, and then sends the IAM to the calling MSC in order to request called party call setup from the overseas communication service provider MSC through the international gateway exchange using the called number at step 609. The calling MSC receives the IAM, that is, the call setup request signal of the called party, from the IP server (or the PPS server), and then sends the IAM to the called overseas MSC at step 611.
[160] The called-side overseas MSC requests an incoming call by sending a paging
message to the called terminal at step 613. At this time, the called party is in a state in which he/she can answer the phone. The called overseas MSC responds to the call setup request by sending an ACM to the calling MSC at step 615. The calling MSC sends the ACM, received from the called overseas MSC, to the IP server (or the PPS server) at step 617. The IP server (or the PPS server) sends the ACM back to the calling MSC in response to the call setup of the calling subscriber at step 619.
[161] The calling customer listens to a ring back tone provided by the called overseas party at step 621. If the called terminal does not respond, the IP server (or the PPS server), that is, the service providing apparatus, detects a no answer state at step 623. In this case, since the no answer time may vary with the country, a no answer timer is set on a country and switch-type basis.
[162] The IP server (or the PPS server) sends the call termination request signal REL to the calling MSC in order to terminate the international incoming call at step 625. The calling MSC transfers the received REL message to the called MSC at step 627. The called MSC terminates the call with the called subscriber, and sends the call termination completion signal RLC to the calling MSC in response thereto at step 629. The calling MSC transfers the received RLC to the IP server (or the PPS server) at step 631.
[163] After the overseas incoming call is terminated, the IP server (or the PPS server) sends a service guidance announcement, indicating the provision of service of the present invention, to the calling subscriber at step 633. In this case, an example of the guidance announcement may include "Please press No. 1 for international call voice message transmission service, and No. 2 for international call automatic call scheduling service." Thereafter, if the calling terminal selects the international call voice message transmission service, the processes subsequent to step 233 of FIG. 2 and the processes of FIGS. 3 and 4 are performed. If the calling terminal selects the international call scheduling service, the processes subsequent to step 233 of FIG. 2 and the processes of FIG. 5 are performed.
[164] FIG. 7 is a view illustrating a call recording service procedure during call
connection based on a subscription-type service according to a preferred embodiment of the present invention. The procedure described in conjunction with this drawing illustrates an "international call real-time call recording service" procedure in which a customer who has subscribed to the service of the present invention (the subscription- type service) attempts an international call, and records the content of communication between a calling party and a called party in real time while making a call with a counterpart. A method of signaling interworking with the MSC, that is, the wireless communication service provider switching apparatus, is described on the basis of SS7.
[165] Referring to FIG. 7, the calling terminal sends a dialing message to the MSC in order to dial the number of a called overseas terminal at step 701. In this case, a general wired/wireless communication customer attempts a call to the called overseas terminal by dialing, for example, "00ABC + country code + area code + called party telephone number," and a PPS customer attempts a call to the called overseas terminal by dialing, for example, "PPS card access number + language selection + card number+ *(#) + country code + area code + called party telephone number."
[166] The calling MSC or the PSTN sends an OrglnfoReq message to the HLR in order to determine whether the calling party customer is a customer who has subscribed to the service providing apparatus service (for example, an international Plus Call) at step 703. The HLR sends customer subscription information about whether the calling party customer is a customer who has subscribed to the present service and routing information to the calling MSC using an OrglnfoResp signal at step 705.
[167] The calling MSC sends an IAM to the IP server (or the PPS server), that is, the service providing apparatus, in order to route the call using the received routing information at step 707. The IP server (or the PPS server), that is, the service providing apparatus, receives the IAM from the calling MSC, and then sends the IAM to the calling MSC in order to request called party call setup from the overseas com- munication service provider MSC through the international gateway exchange using the called number at step 709.
[168] The calling MSC receives the IAM, that is, the call setup request signal of the called party, from the IP server (or the PPS server), and then sends the IAM to the called overseas MSC at step 711. The called overseas MSC sends a paging message in order to call the called customer at step 713.
[169] The called overseas MSC responds to the call setup request by sending the ACM to the calling MSC at step 715. The calling MSC sends the ACM, received from the called overseas MSC, to the IP server (or the PPS server) at step 717. The IP server (or the PPS server) sends the ACM back to the calling MSC in response to the call setup of the calling subscriber at step 719. The calling terminal listens to a ring back tone, provided by the called overseas side, using a communication path connected to the called overseas MSC at step 721.
[170] If the called overseas subscriber responds, the called terminal sends an answer message to the called-side MSC at step 723. The called MSC sends the Answer message to the calling MSC at step 725. The calling MSC sends an Answer Message (ANM) to the IP server (or the PPS server) at step 727. The IP server (or the PPS server) sends the ANM to the calling MSC at step 729. The IP server (or the PPS server) establishes a communication path between the calling party and the called overseas party. At this time, a call between the calling party and the called party can be made at step 731.
[171] The calling customer inputs a specific DTMF at step 733. Step 733 is optional, and recording may begin when the communication path is connected as in step 731.
Furthermore, when the calling party inputs a specific DTMF, recording may begin. If recording begins when a DTMF is input, the IP server (or the PPS server) can output a guidance announcement stating "We will begin recording," to the calling party or the called party. The IP server begins recording the content of voice communication between the calling party and the called party in real time at step 735.
[172] FIG. 8 is a view illustrating an IVR scenario of subscription-type supplementary service according to a preferred embodiment of the present invention.
[173] This drawing illustrates a summarized IVR when a customer who has subscribed to the service of the present invention (the subscription-type service) is provided with international call service through the service providing apparatus using an existing typical telephone number dialing method. That is, this drawing schematically illustrates a scenario of the voice message transmission service, telephone scheduling service and international call recording service of the present invention using the existing international call dialing method ("00ABC + country code + area code + called party telephone number"), or using the prepaid/postpaid card service, such as "PPS card access number + language selection + card number+ *(#) + country code + area code + called party telephone number") in the case of a PPS customer without a Feature Code (FC) using a wired/wireless telephone terminal.
[174] FIG. 9 is a view illustrating a service operation procedure of sending a voice
message to an overseas subscriber using an FC or an SAC according to a preferred embodiment of the present invention. The procedure described in conjunction with this drawing illustrates a procedure in which a calling customer leaves a voice message for an international called customer using an SAC or FC at the time of making an overseas call, and the message is sent through interworking with an overseas VSMS system.
[175] Referring to FIG. 9, the calling terminal sends a call setup request signal to the
MSC by dialing "FC (or SAC) + OOABC + country code + area code + called party telephone number" using an SAC or FC at step 901.
[176] The calling MSC sends a feature request message to the HLR in order to request routing information of the calling party at step 903. The HLR checks the information of the calling party, and sends a Feature Request Return Result (FRRR) signal to the calling MSC at step 905.
[177] The MSC routes a call, including a calling/called number path, to the IP server, that is, the service providing apparatus, with reference to the routing address of the FRRR of the HLR at step 907. The IP server sends an answer (response) signal corresponding to call response to the calling MSC at step 909. The calling MSC makes a call response to the calling terminal at step 911.
[178] The IP server provides the calling terminal with a guidance announcement for international call voice message recording, such as "Please start recording after the 'beep' sound, and press * or # after recording. Beep." at step 913. The calling subscriber leaves a voice message for be delivered to a called overseas party, and completes recording by pressing # (or *) at step 915. In this case, if the calling customer has set a nickname through the WWAS (that is, the wired/wireless Internet access apparatus), the IP server provides an optional function of searching for a corresponding country using the country code of a called overseas party telephone number pressed by the calling party, changing the nickname (another name) of the calling customer to one in a corresponding country language through the LTS according to a corresponding country, and converting the language into a voice for the corresponding country through the TTS server. The IP server sends the voice message, left by the calling subscriber, to the storage devices of the APS and the DBS, and stores the messages in the storage devices at step 917.
[179] The IP server sends a call termination signal to the calling MSC in order to
terminate the call with the calling terminal at step 919. The calling MSC sends the call termination signal to the calling terminal at step 921. [180] The APS determines whether an interworking method (a setting method) provided by the service providing apparatus for overseas interworking is interworking with the VSMS system or the existing international telephone network at step 923. The construction of the overseas VSMS system may include an IP server, an APS, a DBS and an OMS. The names and functions of respective servers may be changed with each other. If, as a result of the determination at step 923, the interworking method is interworking with the VSMS system, that is, message transmission uses interworking between service providing apparatuses or a similar interworking method, the steps subsequent to step 925 are performed. Here, the protocol for the service providing apparatus includes a calling country, a called country, a calling number, a called party telephone number, a message serial number, a message size, a message format (voice/text), immediate/scheduled transmission information, transmission time, and so on.
[181] If, as a result of the determination at step 923, the interworking method is interworking with the existing international telephone network, that is, the voice message of the calling party is transmitted through an overseas communication service provider exchange network through interworking between heterogeneous apparatuses, the procedure of this case is described below with reference to FIG. 10.
[182] At step 925, the APS sends the voice message, recorded by the calling customer, to the overseas VSMS system through the Internet. The APS may send the recorded voice message to the overseas VSMS system through, for example, FTP, etc.
[183] The overseas VSMS system stores the voice message received from the local APS, and determines whether it is a self-service provider network or some other service provider network in order to send the voice message to the called customer at step 927. That is, if setting has been made such that the self-service provider network customer is informed of the reception of a message via an SMS message, notification of the reception of the message can be sent to the self-service provider network customer via an SMS message. If setting has been made such that the self-service provider network customer is informed of the reception of a message via an outbound call, the self- service provider network customer can be informed of the reception of the message via an outbound call. The SMS notification method and the outbound call notification method can be set or changed through the configuration.
[184] If, as a result of the determination at step 927, the method of sending the message has been set to the outbound call notification method, the VSMS system requests call setup from the called MSC at step 929. The called MSC requests call setup from the called terminal. The called overseas customer responds to a received call, and listens to a received voice message through the VSMS system at step 931.
[185] If, as a result of the determination at step 927, the method of sending the message has been set to the SMS notification method, the VSMS system sends an SMS message for providing notification of the reception of the voice message to the SMSC at step 933. The SMSC sends an SMS message, providing notification of the reception of the message, to the called terminal at step 935. The called terminal that has received the SMS accesses the VSMS system through a call back number included in the SMS, and listens to the received voice message at step 937. In this case, before listening to the received voice message, a process of customer authentication may be performed.
[186] After the called party has listened to the entire received message, the VSMS system sends a message, indicating that the called party has received and confirmed the message, to the APS at step 939. The APS sends text information, indicating that the called overseas party has listened to the message, to the calling-side SMSC at step 941. The calling-side SMSC sends an SMS message, indicating that the called party has listened to the message, to the calling customer so that the calling customer can become aware that the called party has received and listened to the message at step 943.
[187] FIG. 10 is a view illustrating a service operation procedure of sending a voice
message to an overseas subscriber using an SAC or an FC according to another preferred embodiment of the present invention. The procedure described in
conjunction with this drawing illustrates a procedure in which a calling customer leaves a voice message for an international called customer using an SAC or FC at the time of making an overseas call, and sends the message through interworking with the existing international telephone network. This procedure corresponds to the steps subsequent to step 923 described with reference to FIG. 9.
[188] Referring to FIG. 10, the APS requests called-side call setup from the calling-side
MSC through the IP server in order to send a voice message, received from the calling terminal, to the called overseas terminal at step 1001. The calling-side MSC requests call setup from the called-side overseas MSC using the outbound call through the overseas international gateway exchange at step 1003. The called-side MSC requests call setup from the called terminal at step 1005.
[189] If the called-side customer responds, the called terminal sends a call response signal to the called-side MSC at step 1007. The called-side MSC sends a response signal to the calling-side MSC at step 1009. The calling-side MSC sends a response signal to the IP server of the service providing apparatus, and the called terminal listens to the voice message received from the calling terminal through a communication path connected to the IP server at step 1011.
[190] The IP server of the service providing apparatus sends information, indicating that the called party has listened to the message, to the APS at step 1013. The APS requests the calling-side SMSC to send an SMS message including notification information, indicating that the overseas recipient has listened to the message, at step 1015. The calling-side SMSC sends a text message, indicating that the called party has listened to the message, to the calling customer so that the calling customer can become aware that the called party has received/listened to the voice message sent by the calling customer at step 1017.
[191] FIG. 11 is a view illustrating a scheduled international call service procedure of scheduling a call to an international called customer using an FC or an SAC when a calling customer makes an overseas call, and automatically connecting the call to a calling party and a called party when a scheduled time has been reached according to a preferred embodiment of the present invention.
[192] Referring to FIG. 11, the calling terminal dials "FC (or SAC) + OOABC + country code + area code + called party telephone number" using an SAC or FC at step 1101. The calling MSC sends a feature request signal to the HLR of the calling party in order to request routing information at step 1103. The HLR checks the information of the calling party, and sends an FRRR signal to the calling MSC at step 1105.
[193] The calling MSC sends a call setup signal to the IP server, that is, the service
providing apparatus, in order to route a call, including a calling/called number path, with reference to routing information (a routing address) included in the FRRR of the HLR at step 1007. The IP server sends an answer (response) signal corresponding to a call response to the calling MSC at step 1109. The calling MSC sends a call response signal to the calling terminal at step 1111.
[194] The IP server sends a service guidance announcement for international call
scheduling, such as "Please input the scheduled date and time," to the calling terminal at step 1113. The calling terminal sends information about the date and time for a scheduled call with the called overseas party to the IP server as a DTMF signal at step 1115. The IP server sends the scheduling information, received from the calling terminal, to the APS and the DBS, and stores it in the APS and the DBS at step 1117.
[195] The IP server sends a call termination signal to the calling MSC in order to
terminate the calling party call at step 1119. The calling MSC terminates the call by sending the call termination signal to the calling terminal at step 1121.
[196] The APS of the service providing apparatus queries the DBS about information scheduled by the calling party, and then periodically checks whether the scheduled time has been reached at step 1123. If the scheduled time set by the calling customer has been reached, the APS checks a method of notifying the calling party of the fact at step 1125. The APS determines whether the calling party has set the outbound call method or the SMS method as the scheduled international call time notification method, and performs a corresponding procedure.
[197] If, as a result of the determination at step 1125, the calling party has set the SMS method as the international call notification method, the APS sends an SMS request signal, informing the calling terminal that the scheduled international call time has been reached, to the SMSC at step 1127. The SMSC sends the SMS, including a call back number of the called party telephone number, to the calling terminal at step 1129.
[198] If, as a result of the determination at step 1125, the calling party has set the
outbound call method as the international call notification method, the APS of the service providing apparatus requests call setup from the IP server so that the calling party is informed that the scheduled international call time has been reached at step 1131.
[199] The IP server of the service providing apparatus requests call setup from the calling
MSC via an outbound call in order to provide notification of the scheduled international call time at step 1133. The calling MSC requests call setup from the calling terminal in order to provide notification of the fact that the scheduled international call time has been reached at step 1135.
[200] If the calling terminal (the customer who has scheduled the international call)
responds to an incoming call, the IP server sends a call setup request signal to the calling MSC in order to request call setup from the called terminal at step 1137. If there is no answer from the calling party, the IP server, that is, the service providing apparatus, can inform the calling terminal of the international call scheduling information through voice before the process for call setup to the called terminal. An example of the scheduling information may include "We will dial scheduled international call abcd-efgh." For reference, in the case where the calling party receives international call scheduling information via an SMS message, a call can be set through the existing international telephone network without via the service providing apparatus in such a manner that the calling terminal directly dials the called party.
[201] The calling-side MSC sends a call setup request signal to the called-side overseas
MSC at step 1139. The called-side MSC sends the call setup request signal to the called terminal at step 1141. If the called customer responds, the called terminal sends a response signal to the called-side MSC at step 1143. The called-side MSC sends a call response signal to the calling-side MSC at step 1145. The calling-side MSC sends the call response signal to the IP server at step 1147. The calling terminal and the called overseas terminal make a call using a connected communication path at step 1149.
[202] FIG. 12 is a view illustrating an international call communication recording service procedure of recording the content of communication with a called party in real time when the calling customer makes a call with an international called customer using an FC or an SAC when the calling customer makes an overseas call according to a preferred embodiment of the present invention. [203] Referring to FIG. 12, the calling terminal attempts a call to a called overseas terminal by dialing "FC (or SAC) + OOABC + country code + area code + called party telephone number" using an SAC or an FC at step 1201. In the calling MSC or PSTN, the calling party customer sends an OrglnfoReq message to the HLR in order to check whether a customer is a customer who has subscribed to the service providing apparatus service (for example, an international Plus Call) at step 1203. The HLR sends customer subscription information about whether the customer is a customer who has subscribed to the present service and routing information to the calling MSC using an OrglnfoResp signal at step 1205.
[204] The calling MSC sends an IAM to the IP server in order to route a call to the IP server, that is, the service providing apparatus, using the received routing information at step 1207. The IP server of the service providing apparatus receives the IAM from the calling MSC, and sends the IAM to the calling MSC in order to attempt a call to the overseas communication service provider MSC through the international gateway exchange using a called number at step 1209. The calling MSC receives the IAM, that is, the call setup request signal of the called party from the IP server, and then sends the IAM to the called overseas MSC at step 1211. The called overseas MSC sends a paging message in order to call the called terminal at step 1213.
[205] The called overseas MSC responds to the call setup request by sending an ACM to the calling MSC at step 1215. The calling MSC sends the ACM, received from the called overseas MSC, to the IP server at step 1217. The IP server sends the ACM back to the calling MSC in response to the call setup of the calling subscriber at step 1219. The IP server informs the calling terminal of the total available recording time using a guidance announcement through Interactive Voice Response (IVR) at step 1221.
[206] The calling terminal receives a ring back tone from the called overseas party at step
1223. The called overseas terminal sends an answer message to the called-side MSC in response to the incoming call at step 1225. The called MSC sends an ANM to the calling MSC at step 1227. The calling MSC sends the ANM to the IP server at step 1229. The IP server sends the ANM to the calling MSC at step 1231. A communication path is established between the calling terminal and the called overseas terminal, so that a call can be made at step 1233. The content of voice communication between the calling party and the called party begin being recorded in real time through the IP server at step 1235.
[207] FIG. 13 is a view illustrating an IVR scenario of a supplementary service using an
FC (or an SAC) according to a preferred embodiment of the present invention.
[208] This drawing illustrates a method of using respective services through wired/ wireless telephone terminals using an SAC or an FC. That is, this drawing
schematically illustrates a service scenario using the voice message transmission service, international call scheduling service and international call recording service of the present invention using service ("FC (or SAC) + OOABC + country code + area code + called party telephone number") using an SAC or an FC using the wired/ wireless telephone terminals.
[209] FIG. 14 is a view illustrating a service procedure in which a calling customer leaves a voice message for an international called customer using an ARS representative number, and sends the voice message to the international called customer according to a preferred embodiment of the present invention.
[210] Referring to FIG. 14, the calling terminal sends a call access request signal to the
PSTN or MSC in order to access the ARS, that is, the service providing apparatus, so as to send a voice message to the called overseas terminal at step 1401. The PSTN (or MSC) performs representative number translation, routes a call to the ARS, and sets up a call at step 1403.
[211] The ARS sends a guidance announcement, requesting the input of the telephone number of the called terminal that will receive the message, to the calling terminal at step 1405. An example of the guidance announcement may include "Please input the called party telephone number. Please input the country code, area code and called party telephone number, and then press # after input." This IVR guidance announcement may be changed according to a service provider. The calling terminal inputs the number of the called overseas terminal according to the IVR guidance announcement at step 1407.
[212] The ARS sends a guidance announcement, requesting that a voice message to be sent to the called subscriber be recorded, to the calling terminal at step 1409. An example of such a guidance announcement may include "Please start recording after the 'beep' sound, and press * or # after recording. Beep." The calling subscriber leaves a voice message, which will be sent to the called overseas party, and completes recording by pressing # (or *), etc. at step 1411. At this time, if the calling customer has set a nickname through the WWAS (that is, the wired/wireless Internet access apparatus), the IP server can provide a function of searching for a corresponding country using the country code of a called overseas party telephone number pressed by the calling party, changing the nickname (another name) of the calling customer to one for a corresponding country through the LTS according to a corresponding country, and converting the nickname in the language into a voice in the corresponding country language through the TTS server. In the subsequent processes, the service providing apparatus stores the voice message, recorded by the calling customer, and the nickname of the calling party (changed to the nickname in the language of the corresponding country), and then sends them to the called overseas terminal.
[213] The ARS provides the calling customer with a guidance announcement indicating immediate transmission or scheduled transmission at step 1413. The calling customer selects immediate or scheduled transmission according to the guidance announcement at step 1415. If scheduled transmission is selected, the calling customer may input a scheduled time, etc. using a DTMF according to an IVR scenario.
[214] The ARS stores the voice message, left by the calling subscriber, in the storage devices of the APS and the DBS at step 1417. The ARS sends a call termination signal to the calling MSC in order to terminate the call with the calling terminal at step 1419. The calling MSC sends the call termination signal to the calling terminal at step 1421.
[215] The APS determines whether an interworking method (a setting method) provided by the service providing apparatus is interworking with the VSMS system (or a gateway apparatus) or the existing international telephone network for overseas interworking at step 1423. The construction of the overseas VSMS system may include an IP server (or the ARS server), an APS, a DBS and an OMS server, and the names and functions of respective servers may be changed with each other.
[216] If, as a result of the determination at step 1423, the message transmission type is a method using interworking between service providing apparatuses or a similar interworking method, steps 1425 to 1441 are performed. Here, the protocol for the service providing apparatus includes the calling country, called country, calling number, called party telephone number, message serial number, message size, message format (voice/text), immediate/reservation transmission information, transmission time, and so on. If, as a result of the determination at step 1423, the interworking method is a method of sending the voice message through the overseas communication service provider exchange network through interworking between heterogeneous apparatuses, steps 1443 to 1459 are performed.
[217] At step 1425, the APS sends the voice message recorded by the calling customer to the overseas VSMS system through, for example, FTP, etc., using the Internet. The overseas VSMS system stores the voice message received from the local APS, and determines whether it is a self-service provider network or some other service provider network in order to send the voice message to the called customer at step 1427. That is, if setting has been made such that the self-service provider network customer is informed of the reception of a message via an SMS message, the reception of the message can be sent to the self-service provider network customer via an SMS message. If setting has been made such that the self-service provider network customer is informed of the reception of a message via an outbound call, the self-service provider network customer can be informed of the reception of the message via an outbound call. The SMS notification and outbound call notification method can be set or changed through configuration.
[218] If, as a result of the determination at step 1427, the method of sending the message is set to the outbound call notification method, the VSMS system requests call setup from the called MSC at step 1428. The called MSC requests call setup from the called terminal. The called overseas customer responds to a received call, and listens to the received voice message through the VSMS system at step 1429.
[219] If, as a result of the determination at step 1427, the method of sending the message is set as the SMS notification method, the VSMS system sends an SMS message for providing notification of the reception of the voice message to the SMSC at step 1431. In this case, the SMS message includes a call back number for accessing the VSMS system. The SMSC sends an SMS message, providing notification of the reception of the message, to the called terminal at step 1433. The called terminal that has received the SMS accesses the VSMS system through the call back number, and listens to the received voice message at step 1435. In this case, before listening to the received voice message, a process of customer authentication may be performed.
[220] If the called party has completely listened to the received message, the VSMS
system sends a message, indicating that the called party has received and confirmed the message, to the APS at step 1437. The APS sends text information, indicating that the called overseas party has listened to the message, to the calling-side SMSC at step 1439. The calling-side SMSC sends an SMS message, indicating that the called party has listened to the message, to the calling customer so that the calling customer can become aware that the called party has received and listened to the message at step 1447.
[221] At step 1443, in order to send the voice message recorded by the calling customer to the called overseas customer, the ARS server requests called-side call setup from the calling-side MSC at step 1443. The calling-side MSC requests call setup from the called-side overseas MSC using an outbound call through an overseas international gateway exchange at step 1445. The called-side MSC requests call setup from the called terminal at step 1447.
[222] The called terminal sends a call response signal to the called-side MSC in response to the call setup request at step 1449. The called-side MSC sends a response signal to the calling-side MSC at step 1451. The calling-side MSC sends a response signal to the ARS server of the service providing apparatus, and thus a communication path is established between the called terminal and the ARS server. The called terminal listens to a received message at step 1453.
[223] The ARS server of the service providing apparatus sends information, indicating that the called party has listened to the message, to the APS at step 1455. The APS requests the calling-side SMSC to send notification information, indicating that the overseas recipient has listened to the message, at step 1457. The SMSC sends a text message, indicating that the called party has listened to the message, to the calling terminal, so that the calling terminal can become aware that the called party has received/listened to the voice message at step 1459.
[224] FIG. 15 is a view of an example of a screen illustrating a method of sending a voice message to an overseas customer using the wired Internet according to a preferred embodiment of the present invention. This drawing illustrates a method (using a User Interface (UI)) in which all types of customers, such as subscription-type customers, non-subscription-type customers, and PPS service customers, send voice messages from one country to another country using the wired Internet.
[225] Referring to FIG. 15, if a customer subscribes to and accesses the wired Internet using a Personal Computer (PC), etc. and then selects the screen of the present invention, a button with which a calling customer can record a voice, a recording state display part, a recording state button (record, stop, play, etc.), a preview (listening) button, a recipient button (an individual input button, a directory selection button, etc.), an immediate/scheduled transmission button, a send button and so on can be displayed. In the message transmission operation for the present service, if voice is recorded using the web and the transmission button is pressed, the voice message can be sent to a called overseas party through interworking with the APS and IP server of the service providing apparatus through the WWAS. In this case, a process in which the service providing apparatus sends the voice message to the recipient follows that described in conjunction with FIG. 3 or the process described in conjunction with conjunction with FIG. 4.

This drawing illustrates a method (UI) in which all types of customers, such as subscription- type customers, non-subscription-type customers, and PPS service customers, convert a text message, written in text, into a voice message, and then send the voice message to a foreign country using the wired Internet.
[227] FIG. 16 illustrates a method in which, when a customer subscribes to and accesses the wired Internet using a PC, etc. and then selects the screen of the present invention, a text message written by a calling customer is converted into voice through the TTS server of the service providing apparatus, and is then sent to a called overseas party. A text input unit includes Korean/English/Japanese/Chinese/Spanish/Russian and the like. The text input unit is configured such that a user can select a language to be converted into and convert text in the selected language into voice. A main menu construction may include an input unit for inputting text, a language selection unit for selecting a language to be converted into voice, a preview (listening) button, a recipient button (an individual input button, a directory selection button, etc.), an immediate/scheduled transmission button, a send button and so on. In the message transmission operation for the present service, when a user inputs text over the web, converts the text into voice using the TTS server, and presses the transmission button, the voice message can be sent to a called overseas party through interworking with the APS and the IP server of the service providing apparatus through the WWAS. In this case, the service providing apparatus may send the voice message to the overseas recipient according to the procedure described in conjunction with FIG. 3 or the procedure described in conjunction with FIG. 4.
[228] FIG. 17 is a view of an example of a screen illustrating a method of scheduling an international call using the wired Internet according to a preferred embodiment of the present invention. This drawing illustrates a method in which all types of customers, such as subscription-type customers of the present invention, non-subscription-type customers, and PPS service customers, schedule an international call using the wired Internet.
[229] Referring to FIG. 17, when a customer subscribes to and accesses the wired Internet using a PC, etc. and then selects the screen of the present invention, a calling customer can schedule an international call with called overseas customers. The construction of the screen can be divided into a recipient information (individual or directory) button, a method of informing a calling party of scheduling information (informed via SMS or telephone), a scheduled time setting unit and the like. The screen may be further divided into simple scheduling (a simple scheduling method, such as scheduling for one hour later, two hours later, ..., [X] hours later), a specific time scheduling function of scheduling a specific time through input, and the like.
[230] In the international call scheduling and service operation for the present service, when a calling customer sets a scheduled international call time and a recipient using the web (the WWAS), the WWAS stores the information, input by the calling customer, in the APS and the DBS. When the scheduled time has been reached, the APS performs a function of informing the calling customer of the scheduled call information through the IP and then automatically making a call to a called customer. In this case, the service providing apparatus can provide the scheduled call service according to the procedure described in conjunction with FIG. 5.
[231] FIG. 18 is a view of an example of a screen illustrating a method of sending a voice message to a called overseas party using the wireless Internet according to a preferred embodiment of the present invention. This drawing illustrates a method (UI) in which all types of customers, such as subscription-type customers of the present invention, non-subscription-type customers, and PPS service customers, send a voice message from one country to another country using the wireless Internet, convert a text message into voice, and then send the voice to a foreign country.

If a specific item, for example, an overseas branch office manager item is selected and input, a scheduling information screen 1907 for the corresponding item is output to the display unit.
[239] When, in the automatic international call scheduling service screen 1903, the
scheduled international call setting item is selected and input, a screen 1909 for in ternational call scheduling is output to the display unit. International call scheduling can be classified into simple scheduling, specific time scheduling, and so on. To this end, the screen 1909 for international call scheduling includes a simple scheduling item and a specific time scheduling item.
[240] When, in the screen 1909 for international call scheduling, for example, the specific time scheduling item is selected and input, screens 1911, 1913 and 1915 for setting a scheduled time are output to the display unit, so that the year, month and day, and hour for an international call may be set. When the confirmation button is pressed after the scheduled time has been input, a screen 1917 for inputting a called party telephone number is output to the display unit. In this case, the called party telephone number input method can use a direct input method or a method of selecting a called party telephone number from the directory and inputting the selected called party telephone number. When the confirmation button is pressed after the called party telephone number has been input, a screen 1919 for confirming international call scheduling is output to the display unit.
[241] When, in the international call scheduling and service operation for the present service, a customer accesses a WAP (ME/KUN) through the WWAS and sets a scheduled international call time and a recipient, the WWAS stores the information, input by the calling customer, in the APS and the DBS. When the scheduled time has been reached, the APS performs a function of informing the calling customer of the scheduled call information through the IP, and then automatically dialing a call to the called customer. In this case, the service providing apparatus can provide the in- ternational call scheduling service based on information scheduled according to the procedure described with reference to FIG. 5.
[242] FIG. 20 is a view of an example of a screen illustrating an international call
recording service method using the wireless Internet according to a preferred embodiment of the present invention. This drawing illustrates a method in which all types of customers, such as subscription-type customers of the present invention, non- subscription-type customers, and PPS service customers, use international call recording service using the wireless Internet.
[243] Referring to FIG. 20, if a customer accesses the wireless Internet, a screen 2001 for international call service is output to a display unit. The international call service screen 2001 includes an international voice message item, an international text message item, an automatic international call scheduling item, an international recording service item and a how to use item.
[244] When, in the international call service screen 2001, a calling customer selects and inputs the international recording service item for recording telephone service with an overseas receiving customer, a recipient input screen 2003 is output to the display unit. The recipient input screen 2003 includes a direct input item for directly inputting the number of a recipient, and a directory input item for inputting information about a recipient stored in a directory.
[245] When, in the recipient input screen 2003, for example, the direct input item is
selected and input, a direct input screen 2005 for inputting the number of a recipient is output to the display unit. When, in the direct input screen 2005, the number of the recipient is input and a confirmation button is pressed, a connection confirmation screen 2007 is output to the display unit for international call recording service. When, in the connection confirmation screen 2007, the confirmation button is pressed, the calling terminal dials a called overseas terminal corresponding to the called party telephone number through the service providing apparatus, and the content of communication between the calling terminal and the called terminal is recorded in the service providing apparatus. In this case, the procedure in which the calling terminal dials the called overseas terminal is the same as that described with reference to FIG. 9.
[246] When, in the present screen construction, for example, the international call
recording service is selected, the international call recording service can be used by selecting a recipient input unit (selection of a recipient through direct input/directory), a connection menu, and so on. When, in the international call recording service operation for the present service, a customer accesses a WAP (ME/KUN) through the WWAS and selects the international call recording service, the WWAS may store information input by the calling customer in the APS and the IP server, and can record the content of communication with the overseas receiving customer. The IP server performs a function of recording the details of communication between the calling party and the recipient.
[247] FIG. 21 is a view illustrating a method of sending text and voice messages using a wired/wireless terminal function according to a preferred embodiment of the present invention. This drawing illustrates a procedure and method for converting a text message into voice using a wired/wireless telephone terminal function, or sending the recorded voice message to a called overseas customer through interfacing with the service providing apparatus.
[248] Referring to FIG. 21, if a user of a calling terminal, that is, a wired/wireless
terminal, selects and presses the message button 201 (or a special key, a hot key for the present invention, or the like) of the terminal, the terminal outputs a message management screen for text message reception confirmation, message transmission, etc. to a display unit. The message management screen includes a received message item, a sent message item, a sentence storage box item, an emoticon storage box item, a message communication record item and the like.
[249] When the terminal user selects and inputs the sent message item in the message management screen, a message writing screen 2103 is output to the display unit. The message writing screen 2103 includes a voice message transmission item for voice message transmission, and a text message transmission item for text message transmission.
[250] If the voice message transmission item is selected and input in the outgoing
message writing screen 2103, a screen 2105 for the input of a called party telephone number is output to the display unit.
[251] In this case, the user can input one or more called party telephone numbers in the called party telephone number input screen 2105. In this case, the called party telephone number can be input in the form of, for example, "00ABC + country code + area code + called party telephone number." "00ABC," that is, an international call service provider identification number, may be omitted depending on the service provider.
[252] When a confirmation button is pressed after the input of the called party telephone number has been completed, a screen 2107 for inputting a calling party telephone number is output to the display unit. In this case, basically, the calling party's own number is automatically output from the calling terminal, and the calling party can input an outgoing telephone number, through which the calling party wants to receive a call, in place of the calling party's own number.
[253] If information about the outgoing number is input in the screen 2107 for inputting the calling party telephone number, a screen 2109 for confirming the transmission of a received number is displayed. If the confirmation button is pressed, the calling terminal sends information (the called party telephone number and the calling party number), which is input from the calling customer, to the service providing apparatus so that a voice message is recorded through the service providing apparatus. In this case, the method of sending information input in the calling terminal to the service providing apparatus follows a procedure identical to that described with reference to FIGS. 2 to 4 or that described with reference to FIGS. 9 and 10. In other words, when the screen 2109 for confirming the transmission of a received number is displayed and the confirmation button is pressed, the calling terminal can access the service providing apparatus by sending a call setup request signal to the calling-side MSC using the input received number, etc.
[254] When the calling terminal has accessed the service providing apparatus through a specific access number (for example, 010-200-7777), a voice guidance announcement, such as "Please start recording after the 'beep' sound, and press # after recording. Beep.," is output to the calling terminal. In this case, when a calling telephone customer records the voice message, the service providing apparatus sends the stored voice message to a called overseas customer through the service providing apparatus.
[255] When the text message transmission item is selected and input in the outgoing
message writing screen 2103, a screen 2111 for text message transmission is output to the display unit. The screen 2111 for text message transmission includes a text transmission (or multi-mail transmission) item and an after- voice-conversion transmission item. The text transmission (or multi-mail transmission) menu item is the same as an existing text message or multi-mail writing menu item. The after- voice-conversion transmission menu item is a menu item for converting text into voice using the present invention, and then sending the voice message to a called party.
[256] When the text transmission item is selected and input in the screen 2111 for text message transmission, a screen 2113 for text message writing is output, and the user can write a text message to be sent to a recipient. In this case, the written text message is based on a vernacular language, and can be written in other languages, such as English. The text input language selection menu item has to be provided in a terminal.
[257] When the confirmation button is pressed after the text message has been written in the screen 2113 for writing the text message, a screen 2115 for inputting the called party telephone number is output to the display unit, so that the user can input one or more called overseas party telephone numbers. In this case, the called party telephone number can be input in the form of, for example, "00ABC + country code + area code + called party telephone number." "00ABC," that is, an international call service provider identification number, may be omitted depending on the service provider.
[258] When the confirmation button is pressed after the input of the called party telephone number has been completed, a screen 2117 for inputting the calling party telephone number is output to the display unit. In this case, basically, the number of the calling terminal is automatically output from the calling terminal, and the calling party can input an outgoing telephone number, through which the calling party wants to receive a call, in place of the existing calling party's own number.
[259] When the confirmation button is then pressed after the input of the calling number has been completed, a screen 2119 for voice conversion language selection, in which a language, to which conversion will be made for a voice to be sent to the called party, can be selected, is displayed to the display unit.
[260] When the confirmation button is pressed after the language to be converted into has been selected, a screen 2121 for voice message transmission is output to the display unit. The voice message transmission screen 2121 includes a preview item and a transmission item. The calling party can listen in advance to a text written by the calling party, and can select immediate transmission, or scheduled transmission. In the case of scheduled transmission, the calling party inputs scheduled date, a scheduled time, etc. in compliance with the input requirements of a terminal.
[261] When the calling party presses the confirmation button after inputting all information, the calling party accesses the service providing apparatus through a specific number (for example, 010-200-7777) between the calling terminal and the service providing apparatus, writes a message in text in the terminal, and sends a voice message, converted into voice, to the called overseas party. In this case, the text message written by the calling party is sent to the service providing apparatus in an SMS form. The service providing apparatus converts the text message into a corresponding voice message, stores the converted voice message, and sends the stored voice message to the called overseas party according to the procedure described in conjunction with FIGS. 3 and 4.
[262] The present invention is not limited to these embodiments, and many modifications may be made by those skilled in the art without departing from the scope and spirit of the invention.
