Description

SERVICE DEVICE AND CHARACTERISTIC FUNCTION EQUIPMENT WITH INTERNATIONAL INTERNATIONAL VOICE, TEXT RECEIVED INTERNET RECEIVING OF WIRED AND WIRELESS SIGNALS

The present invention relates to enabling users to automatically and simultaneously reduce the cost and convenience of use of telephone and text services in domestic, international, and roaming communications, which are inconvenient for users. Is for subscribers of wired / wireless telecommunications who suffer from high cost and changes in usage caused by the complex identification number system in each country and region and the movement of the telecommunication service company, country or region. In addition, the present invention provides a familiar numbering system and usage method in the environment of each home country, if the user of the present invention is a mobile terminal to which all identification numbers are assigned, whether smartphone or general phone, IP-based wired, wireless Internet network and general wired. Even in the wireless telephone network, even if each area and communication environment are different It ensures that the convenience, anywhere in the world when the present invention is even able to make cheap and easy access to local services and international and domestic calls and text services. In the case of Korea, the mobile phone operator performs a 30% to 50% savings compared to the national standard rate, and also relates to an inexpensive outgoing call that saves more than 90% in international roaming. Domestic voices, domestic texts, international voices, international texts of wired and wireless subscribers in order to provide saving and receiving services of global roaming effect that can receive calls and texts using numbers or designated identification numbers used in the home country anytime, anywhere in the world. The present invention relates to a service device equipped with an automatic receiving / receiving registration function and a method of operating the rate saving function.

In the existing technical communication environment, wired / wireless communication subscribers may change the number system or communication method of the local carrier when visiting a foreign country or a remote area due to a change of the country or service provider using the communication service or travel. As a result, users have to change their number or terminal and change their plans. Or only manually through a specialized function with the ability to understand each user's environment inconveniently, consuming high costs and time, only through operators in specific regions who are in charge of each specialized area that knows the local communication environment. I'm going.

Currently, various countries provide various types of call forwarding services and international roaming services, but they do not solve all the inconveniences.

For example, in the case of roaming between regions or countries, carriers in each region, that is, carriers of foreign countries (eg, the United States, Japan, etc.) cooperate with each other to connect the service networks of the respective carriers. At this time, when a user subscribed to a specific carrier wants to use his or her number and terminal in a foreign country such as the United States or Japan, he or she may perform text transmission, data use, call, etc., if the other foreign carrier is in the service area. There is a communication service that can be, but this is limited to the case that the communication environment of the terminal and the visited network meets the necessary conditions to be equally applicable to the communication environment of the home network.

In spite of the efforts made in the related art, various mobile service providers in each country have assigned their own subscriber identification numbers to charge expensive outgoing and receiving fees, so that domestic mobile communication service users provide international roaming services in foreign countries. In case of receiving, it is inconvenient to use the subscriber's identification number assigned in Korea, and it is inconvenient for foreign locals to remember the number system different from that of their own country. Even when making a call or receiving a call from a person in a short distance, there was a problem in that communication was made through an international call.

In addition, in order to enjoy familiar and inexpensive communication services to locals in a foreign country, when subscribing to a service provided by a local carrier, a new subscriber identification number is required, It is difficult to manage because a large number of subscriber identification numbers must be assigned to each country. There was discomfort.

In general, there is an incoming call service provided manually by conventional carriers. The called phone number change service is a telephone number of a landline telephone or a mobile communication terminal that can be called by a user who has subscribed to the called phone number change service. The call forwarding service server refers to a service for connecting a call to a registered call forwarding number to a registered forwarding call number. Services targeted for call forwarding services include wired / wireless communication services such as voice call, short message, multimedia message, instant messenger, and voice mail.

Referring to FIG. 1 of Korean Patent Laid-Open No. 2011-0082350, a principle of changing an incoming phone number is illustrated. Member B is registered with the incoming telephone number change service. The user registers the telephone number of C as the destination telephone number for subscriber B through the network communication network with the terminal C telephone number or any other communication system. Therefore, when a call attempt from any subscriber A to subscriber B occurs, the network communication network attempts to call C without attempting to call subscriber B. Here, the network communication network is a concept including a mobile communication network and a public switched telephone network (PSTN) network including a wireless base station and a telephone switching center. In other words, it is subscriber centered, not terminal.

In general, voice over internet protocol (VoIP) technology has recently been in the spotlight for reducing communication charges through efficient use of existing network resources and ease of management through integration of telephone and data networks. As technology has advanced, a dedicated gateway server for Internet calls has emerged, acting as an interface between the Internet and the public switched network. The gateway server is equipped with a voice processing card, allowing users to make Internet calls using their existing telephones from customers of wired and wireless carriers.

Such Internet phones are spreading rapidly because they are superior in terms of network efficiency and cheaper than general phones using public switched networks. However, since the Internet phone has to go through a gateway, the method of use is complicated, so it is not used for local calls but mainly for international calls.

On the other hand, when using the international roaming service in the existing public switched network, if a person with a domestic phone number stays in a foreign country for business trips, etc., someone who does not know this in Korea calls the person's phone number and receives a guide message. It was possible to automatically dial the local telephone number of a roaming service user in a foreign country. However, the international telephone roaming service of such a public switched network is very expensive and its use is restricted.

Subscriber Identity Module (SIM) card is a card with an integrated circuit chip, and various mobile communication terminals such as Global System for Mobile Communication (GSM) or Wideband Code Division Multiple Access (WCDMA). Is used for subscriber identification.

In the communication system, a subscriber identification module (hereinafter referred to as SIM), which is typically inserted into a mobile terminal, is a card type module, and typically stores subscriber information for providing various services such as subscriber authentication, billing, and security functions. (Chip). In a communication system requiring subscriber authentication by the SIM, the SIM may be used because the SIM is essential to the mobile communication terminal.

As a mobile terminal using a SIM card, a form having one SIM card slot has been common, but recently, a dual SIM card type mobile terminal using two SIM cards is also introduced. Become

Nevertheless, in order to obtain the information of the SIM cards that the user is using, the user has to go through various manipulation procedures for accessing the information essential for various call operations of the SIM card.

In general, in order to make a local call, a long distance call, or an international call, it is common to directly dial a counterpart's telephone number to be called only through the service provider to which the subscriber is subscribed, and another method is to sell a prepaid card. There are various methods of accessing complex steps through separate operators or operators.

However, there is a problem that expensive telephone call charges are charged when using the methods that have been provided to general subscribers in this way, so that users often end calls prematurely due to high charges.

In addition, in the case of general roaming, both mobile communication networks and international networks have to go through, causing waste of the mobile communication network, and there is a problem that a fee is charged two to three times higher than a general international call rate.

Therefore, there is an urgent need for both domestic and foreign call service, which is low in call rate and easy to use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, .

1 is a diagram showing data and call flows in a system for providing domestic and foreign call service according to an embodiment of the present invention.

The domestic and foreign call receiving service system according to an embodiment of the present invention can change the SIM card or change the local number system through a program embedded in an application installed on the mobile communication terminal possessed by a service subscriber or an additional device that can be mounted on the mobile communication terminal. When the change is recognized, the changed SIM card information or local number system information is automatically registered in the service server, so that even if a service subscriber outside the country receives or makes a call using the corresponding mobile communication terminal, the phone number subscribed to the domestic mobile communication network As the call is made, cheap and excellent sound quality is characterized in that the call is made.

Hereinafter, in the present specification, the first region corresponds to a home network as a service subscriber wants to limit to domestic calls, and the second region corresponds to a visited network as a region where a mobile communication company of the first region cannot provide domestic mobile communication services. It means other regions except the first region. The region or country desired by the subscriber of the service can be freely designated as the first region. For example, a domestic subscriber will basically designate Korea as the first region, but in some cases, China or the United States as the first region. There will be.

In this embodiment, the service subscriber is located in the second region (outside), so that the local SIM card is installed in the mobile terminal used in the first region (domestic) or the mobile terminal newly opened in the second region (outside) is used. When the service card 100 recognizes a change in the SIM card or the local numbering system through an application for providing domestic and international incoming / outgoing services installed in the corresponding mobile communication terminal or a program embedded in an additional device connected to the input / output terminal of the mobile communication terminal. Assume that you have registered automatically. This will be described in detail later with reference to related drawings.

The service server 100 assigns a personal number to the service subscriber, and automatically transfers the call forward to the personal number for the first area opening number of the service subscriber. Here, the personal number is a personal identification number specified by domestic and overseas call originating service subjects, and is a unique telephone number distinguished for each service subscriber. In the present invention, the personal number is a telephone number for making a call connection to the service server 100. The personal number may be, for example, a lifetime number provided by a lifetime number service such as 0505 service.

Thereafter, the service server 100 automatically recognizes the change of the SIM card information or the change of the local number system when the service subscriber uses the new SIM card or the new mobile communication terminal in the second region, or by user input. Receive the information about the second area opening number which the service subscriber uses in the second area through the recognized application or program and store it in the database.

First, the service subscriber in the second region receives a call as follows.

When the caller located in the first region attempts to make a call to the service subscriber's first area opening number (step S10), the call forwarding is automatically made to the personal number assigned to the service subscriber, and the call is made to the service server ( 100) (step S12).

The service server 100 performs the call to the second area opening number of the corresponding service subscriber stored in the database (step S14), and performs a call routing between the first area caller and the service subscriber to make a smooth call.

In this case, the call connection from the mobile communication terminal of the first region caller to the service server 100 corresponds to a domestic call in the first region, and the mobile communication terminal 200 of the service subscriber in the second region from the service server 100. Call connection to) corresponds to the domestic currency in the second region, which is much cheaper than the general international roaming service.

Next, when a service subscriber in the second region attempts to make a call, a callback method is used and the detailed process is as follows.

When the service subscriber in the second region attempts to call by running an application or program (step S20), the application or program transmits call request information including caller information and receiver information to the service server 100 (step S22). ). The call request information may be transmitted through a data network such as an IP communication network.

The service server 100 transmits to the caller (i.e., the service subscriber) based on the caller information included in the call request information (step S24), and the application or program automatically receives it (step S26). The automatic reception eliminates the inconvenience that the service subscriber has to hang up after receiving a call and then receive the call again, and the service subscriber can feel the same as the general calling process.

The service server 100 transmits and connects to domestic and international receivers based on the receiver information included in the call request information (step S28), and connects a call connected to a service subscriber and a call connected to a domestic and overseas receiver. To make a call between you and the domestic and international recipients.

Hereinafter, the configuration and function of the service server will be described in detail.

2 is a diagram schematically illustrating a configuration of a service server according to an embodiment of the present invention.

Referring to FIG. 2, the service server 100 includes a customer database 110, an automatic registration manager 120, and a call controller 130.

The customer database 110 stores customer information on service subscribers who have subscribed to domestic and overseas service. Customer information includes a customer identification code (eg, name, ID, etc.) to identify the service subscriber, a password for authentication of the service subscriber, a first area opening number registered by the service subscriber, and a first area opening number. For example, a personal number assigned to the service subscriber, or a second region opening number opened in the region where the service subscriber is currently located (ie, the second region). The second area opening number is a new registered or prestored number received from a mobile terminal when the service subscriber moves to the second area and joins the local mobile communication service in the second region or when he / she wants to use the domestic and overseas call service. Renewal can be registered.

The auto-registration manager 120 stores the customer information input during the service subscriber subscription process at home and abroad in the customer database 110. In this case, the customer information entered by the service subscriber basically includes a customer identification code, a password, and a first region opening number.

And the automatic registration management unit 120 is assigned a personal number for the service subscriber, and includes it in the customer information of the service subscriber. In the future, when a request for activation of domestic and overseas inbound and outbound services is requested, the first area opening number is forwarded to the personal number assigned to the same service subscriber.

The auto-registration management unit 120 newly adds the second region opening number to the customer information identified by the customer identification code according to the automatic registration request (including the customer identification code and the second region opening number) from the mobile communication terminal 200. Or register for renewal. When the registration of the second area opening number is completed, the auto registration manager 120 may transmit a response message indicating the completion of auto registration to the mobile communication terminal 200.

In addition, the automatic registration management unit 120 automatically transfers the first area opening number included in the customer information to the personal number according to the automatic registration request or service activation request from the mobile communication terminal 200. As a result, the call request to the first area opening number is transferred to the personal number so that the call control unit 130, which will be described later, recognizes this and can perform call routing to the second area opening number.

Alternatively, the automatic registration management unit 120 may automatically transfer the second area opening number to the called number for the first area opening number instead of the personal number. In this case, whenever the SIM card information or local number system information is changed by the movement of the service subscriber, the called number is changed to a new number of the mobile communication terminal and automatically registered in the service server 100 so that the incoming call can be connected anywhere in the world. do.

Automatic call forwarding can be achieved by sequentially performing service connection number input, DTMF transmission, and incoming number input, for example, as a remote control service of SK Telecom. Or forwarding a forwarding number for automatic setup of a call forwarding by providing information according to one of the following methods: mobile IP (web) DTMF tone, short message service (SMS), multimedia message service (MMS), and display a specific call number. This may be done. The provision of such information may be made through a wired or wireless network such as, for example, a mobile communication network, a PSTN network, or an internet network.

If there is a service deactivation request from the mobile communication terminal 200, the automatic registration management unit 120 terminates the call forwarding so that the mobile communication terminal 200 receives the call to the first area opening number. This is because, in the case where the service subscriber returns to the first region again, the general call service is sufficient.

The call control unit 130 establishes a call routing path between the personal number included in the customer information and the second area opening number, and sends a call to the second area opening number for the call request to the personal number so that a call connection is made. . That is, the call request to the first area opening number is forwarded to the personal number and is followed by the second area opening number. If the second area opening number is the called number instead of the personal number, the call request to the first area opening number may directly lead to the second area opening number.

In addition, the call controller 130 provides a call connection through a callback service for the call request from the mobile communication terminal 200 in which the service is activated. The call request includes caller information including one or more of a customer identification code, a first area opening number, a second area opening number, and a recipient information including a call request number.

Therefore, the call control unit 130 attempts to access the first call by calling the mobile communication terminal 200 which has transmitted the call request using the second area opening number identified by the caller information, and the call request included in the receiver information. The number 2 attempts to connect to the domestic and international wired and wireless receiver using the number. When both the first call connection and the second call connection are made, it is connected so that a smooth call is made between the caller (subscriber) and the receiver (subscriber call request target).

In addition, the call controller 130 may perform billing according to a reception or / and a call time according to a customer identification code identified by caller information.

3 is a diagram schematically illustrating a configuration of a mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 3, the mobile communication terminal 200 may include a communication unit 210, a storage unit 220, an interface unit 230, and a control unit 240, and the control unit 240 may include a SIM card information management unit ( 242 and a call manager 244. Although not shown, it is obvious that the mobile communication terminal 200 may further include additional components (for example, input / output means such as a touch screen, multimedia data processing means, etc.) to perform a function provided by the mobile communication terminal 200. Since there is a little distance from the gist of the present invention, description thereof will be omitted. In addition, one or more of the illustrated components may be implemented in the form of hardware means or a software program.

The mobile communication terminal 200 according to the present embodiment is a portable terminal capable of installing a dedicated application related to domestic and overseas call service, for example, Apple's iOS, Google's Android, and Microsoft's Win7Phone. It may be a smartphone equipped with an operating system for a portable terminal, such as a tablet PC or the like. In this case, the SIM card information managing unit 242 and the call managing unit 244 may be included in a dedicated application related to domestic and overseas call service, and may be driven in the background after being executed once.

In addition, the mobile communication terminal 200 according to the present embodiment is a type of mobile communication terminal that can be replaced with the SIM card 250, and automatically recognizes the change of the SIM card 250 and changes the SIM card information to the service server 100. Although it is assumed that the transmission to), it is obvious that the scope of the present invention is not limited thereto.

The SIM card 250 is an IC card implementing the subscriber identity module and is an essential element of a mobile communication terminal that conforms to the GSM standard as described above. Similar subscriber identification modules include the Universal Subscriber Identification Module (USIM) card used in third generation mobile (3G / 4G) terminals by extending the SIM of the GSM standard, and the aforementioned SIM card following the CDMA standard. Removable User Identity Module (RUIM) cards improved for use in mobile communication terminals, CDMA Subscriber Identity Module (CSIM) cards, which are removable smart cards that can be used in CDMA networks, and the like.

Subscriber identification module cards (hereinafter, referred to as SIM cards), such as the SIM card, USIM card, RUIM card, and CSIM card described above, are generally used in a slot inside a rear cover of a mobile communication terminal. The SIM card's internal memory contains one or more subscriber information, such as service provider information and user authentication information, and local opening numbers, international mobile equipment identifiers (IMEIs), and mobile subscriber ISDN numbers (MSISDN). Since one or more terminal-specific information is stored, the user can install the SIM card issued in the second region in the mobile communication terminal used in the first region and use it as the mobile communication terminal in the second region.

Here, IMEI is a unique value in GSM / WCDMA and satellite phones, which is a maximum 15-digit hardware number consisting of a 14-digit code and a 1-digit check value, and describes the terminal manufacturer, model, and serial number. The MSISDN is a public reference for a subscriber and corresponds to a telephone number of a mobile communication terminal. The MSISDN includes a country code (MCC), a network code (MNC) and a directory number.

The communication unit 210 may include one or more modules that enable wireless communication between the mobile communication terminal 200 and the service server 100 under the control of the control unit 240. For example, the communication unit 210 may include one or more of a mobile communication module, a wireless Internet module, and the like.

The communication unit 210 may use an IP communication network and / or a PSTN network, and may request various kinds of requests from the mobile communication terminal 200 (for example, an automatic registration request, transmission of call request information, service activation / deactivation request, etc.). Data transmission is performed through an IP communication network, and call connection such as origination from the service server 100 through call routing or origination from the service server 100 by a callback method may be performed through the PSTN network.

The storage unit 220 includes one or more subscribers among SIM card information (for example, carrier information, user authentication information, etc.) received from an operating program for driving the mobile communication terminal 200 and a SIM card mounted in a slot provided. Information, local opening numbers, terminal-specific information such as one or more of IMEI, MSISDN, etc.), and customer information (for example, customer identification code, first region opening number, etc.) of subscribers who have subscribed to domestic and overseas service. Can be stored. In addition, the sim card information includes at least one of the first region sim card information received from the first region sim card and the second region sim card information received from the second region sim card.

The interface unit 230 performs a passage function for transmitting and receiving a signal with the SIM card 250 mounted in the slot. That is, the interface unit 230 transmits various control commands (for example, a SIM card information providing command, etc.) to the SIM card 250, and receives the SIM card information from the SIM card 250 to control the controller 240. To provide.

The controller 240 controls the functions of each component of the mobile communication terminal 200.

The controller 240 may include a SIM card information manager 242 and a call manager 244.

The SIM card information management unit 242 recognizes the SIM card 250 installed in the slot and has various control commands through the interface unit 230 to have the SIM card information provided with the SIM card 250 or SIM card information. The SIM card 250 or the SIM card information received from the OS of the mobile communication terminal 200 is stored in the storage unit 220.

In addition, the SIM card information manager 242 may check whether the SIM card installed in the slot is changed at the time when power is applied, and perform automatic registration processing to the service server 100 when there is a change. A series of processes for performing SIM card change confirmation and automatic registration processing will be described later with reference to related drawings.

The call manager 244 generates call request information and transmits the call request information to the service server 100 when a mobile communication terminal 200 attempts to call through a dedicated application, and automatically receives a callback from the service server 100. do. The call request information includes one or more of a customer identification code, a first region opening number, and a local opening number (if the SIM card is issued in the second region, corresponding to the second region opening number) stored in the storage unit 220. Receiver information, including caller information and call request number.

When the callback is made from the service server 100 to the second area opening number according to the call request, the call manager 244 automatically receives the call and maintains the call connection state with the service server 100. The call management unit 244 automatically hides a series of processes that allow the user to hang up and receive the call again after the request is maintained. Therefore, it does not require many user operations and makes the user feel the same as a general outgoing call. It is effective to prevent feeling.

In addition, the call manager 244 may transmit a request to the service server 100 to determine whether to activate the domestic and overseas call-out service for the mobile communication terminal 200. The service activation request is made by activating the incoming and outgoing service at home and abroad to automatically forward the call to the personal number of the first area opening number (or the automatic call forwarding to the second area opening number of the first area opening number) in the service server 100 is made. The reception is made smoothly, and the call connection according to the callback method is made when the call is requested. The service deactivation request terminates the automatic call forwarding at the service server 100 and allows a general call to be made.

In addition, the call manager 244 provides basic functions related to a call. Basic functions related to call include dial function, call function, recent call list function, phone book function, micropayment function, usage history inquiry function, and so on.

In the above description, it is assumed that the automatic registration manager 120 and the call manager 244 included in the controller 240 are included in a dedicated application installed in the mobile communication terminal 200. However, in some cases, the application may not be installed in the mobile communication terminal. In this case, by embedding a program that performs the functions of the auto-registration management unit 120 and the call management unit 244 in the removable device to the input and output terminal of the mobile communication terminal, the same operation as the dedicated application is performed by the attachment of the additional device. You can also

The mobile communication terminal 200 may further include a location information extractor (not shown). The location information extracting unit is configured to display the current position of the mobile communication terminal from a GPS value or an LBS value obtained from a GPS (Global Positioning System) module (not shown) or a LBS (Location Based Service) module (not shown) included in the mobile communication terminal 200. Extract location information about the location. Acquisition of the LBS value using the acquisition of a GPS value using a GPS satellite, a triangulation such as a base station or a response to a query to a home location register (HLR), etc. will be apparent to those skilled in the art, and thus detailed description thereof will be omitted.

When the location information of the first region country is stored in the storage unit 220, the auto-registration management unit 120 compares the location information extracted by the location information extraction unit to the current service subscriber in an area other than the first area, that is, You can check whether you are located in the second area. When the country of the present location is identified as a result of the analysis of the location information, information including the corresponding country code and the operator identification number may be formed and transmitted to the service server 100.

This is a method to reduce the SIM card installation error or location recognition error when the service subscriber is located near the border line, and even if the user confuses the SIM card of another country or the terminal of another station, the location information extracted from the location information extractor is transmitted. By comparing the identification information received, you can prevent this mistake by notifying the customer if they have a bad SIM card that they cannot use at their current location. The error correction method using the location information may be optionally processed by user setting.

4 is a flowchart of a method of performing a SIM card change confirmation and an automatic registration process in a mobile communication terminal according to an embodiment of the present invention, and FIG. 5 is a flowchart of a method of confirming a SIM card change according to an embodiment of the present invention. .

Referring to FIG. 4, a method of performing SIM card change confirmation and automatic registration processing is illustrated as an operation method of domestic and international call receiving services performed in the mobile communication terminal 200.

Power is applied to the mobile communication terminal 200 in step S300. At this time, the control unit 240 operates so that the automatic registration management unit 120 operates.

In step S310, the automatic registration management unit 120 determines whether the SIM card 250 mounted in the slot has been changed. A determination process of whether or not the SIM card is changed will be described in detail below.

Referring to FIG. 5, in step S400, the automatic registration management unit 120 controls a command (sim card information providing command) to the operating system of the SIM 200 or the mobile communication terminal 200 having the SIM card information installed in the slot. Send SIM card information. In the exemplary embodiment of the present invention, the SIM card 250 is mounted in a state in which power is supplied to the mobile communication terminal 200 as well as the power is supplied to the mobile communication terminal 200 after the SIM card 250 is mounted. Applicable even if

In operation S410, the auto registration manager 120 that acquires the SIM card information from the SIM card 250 or the operating system checks whether there is previously stored SIM card information in the storage 220. As a result of the check, if there is previously stored SIM card information, the automatic registration management unit 120 reads previously stored SIM card information in step S420, and if there is no previously stored SIM card information, the process proceeds to step S450. come.

Thereafter, in step S430, the automatic registration management unit 120 compares the sim card information obtained in step S400 with the sim card information read from the storage unit 220 and checks whether they match with each other.

If there is a match in step S440 auto-registration management unit 120 determines that the SIM card has not changed, and if it does not match, in step S450 auto-registration management unit 120 determines that the SIM card is changed, the newly changed SIM card information To store in the storage unit 220.

Referring back to FIG. 4, in addition, the auto-registration manager 120 may automatically check whether the SIM card is changed at every predetermined time. Alternatively, the auto-registration manager 120 may check whether the SIM card is changed, for example, when setting confirmation is requested by a user's screen touch or button input.

In addition, when the automatic registration management unit 120 is not included in a dedicated application installed in the mobile communication terminal 200 but is included in a program embedded in the additional device connected to the input / output terminal of the mobile communication terminal 200, the attachment or detachment of the additional device is removed. Alternatively, step S310 may be performed every time a predetermined button provided in the additional device is clicked.

If it is determined that the SIM card has not been changed, the process proceeds to step S350 according to the previously registered second area opening number or, if there is no registered second area opening number, according to the first area opening number. Performs operations such as automatic reception.

If it is determined that the SIM card is changed, the process proceeds to step S320, and the automatic registration manager 120 transmits the SIM card information providing command to the SIM card 250 to extract the SIM card information. The SIM card information to be extracted is terminal-specific information. The local opening number or MSISDN corresponds to the second region opening number to be newly registered, and the IMEI is a terminal hardware number for which the second region opening number can be searched.

In step S330, the automatic registration management unit 120 transmits the extracted SIM card information (particularly, the second region opening number) to the service server 100 together with the automatic registration request. The autoenrollment request may include customer information (e.g., one or more of an International Mobile Subscriber Identify (IMSI), subscriber identification code, or first area opening number) to identify the service subscriber to be renewed. have. Here, the IMSI includes a mobile country code (MCC), a mobile network code (MNC), and a mobile subscriber identification number (MSIN).

When the auto-registration request is initially transmitted in step S330, the call forwarding automatic setup request may be transmitted together.

Upon receiving the auto-registration request, the service server 100 registers the second region opening number in the customer database 110 in a new or updated manner according to the service subscriber identified by the customer information included in the auto-registration request, and registers the registration result. The response is transmitted to the mobile communication terminal 200. The second area opening number may be a local opening number or MSDISN included in SIM card information sent with the auto-registration request. Alternatively, the second area opening number may be a local opening number retrieved from the IMEI included in the SIM card information transmitted with the auto-registration request.

In addition, when the service server 100 receives the call forwarding automatic setup request, the service server 100 sets the call forwarding to the personal number assigned to the service subscriber or the second area opening number to the service subscriber. Allow calls to the opening number to be directed to an individual number or a second area opening number. When the incoming call forwarding automatic setting is completed, the result is also transmitted to the mobile communication terminal 200.

In operation S340, the automatic registration management unit 120 determines whether the processing result for the automatic registration request and / or the call forwarding automatic setting request is received from the service server 100, and if there is a processing result that is not received, proceeds to operation S330. After a certain time elapses, the request transmission corresponding to the processing result that is not received is retried.

In addition, the automatic registration management unit 120 may receive a manual registration request requiring manual registration because the automatic registration failed as a result of the processing from the service server 100. In this case, the manual registration of the second area opening number may be requested. You may be able to display the screen and enter it directly from the user.

If all the processing results corresponding to the successful execution of the request are received, the new or renewal registration of the opening number of the second region is completed, and the flow proceeds to step S350 to display the processing results on the screen, and the reception or / And it informs that the operation can be performed for the call.

The display of the processing result is a process for checking the user, and may be displayed on the screen of the mobile communication terminal, for example, "the information of your terminal has been changed to 0130-4567-8900 (local opening number)". . The display of this processing result may be omitted by user setting.

In addition, the automatic registration management unit 120 may store the second area opening number in which the automatic registration processing is completed in the storage unit 220 to obtain an effect of preventing a service interruption or an error due to a service change or a number change.

Of course, the above-described SIM card change confirmation and automatic registration method may be performed by an automated procedure in a time series order by a program embedded in or installed in a digital processing apparatus. The codes and code segments that make up the program can be easily deduced by a computer programmer in the field. In addition, the program is stored in a computer readable medium readable by the digital processing apparatus, and is read and executed by the digital processing apparatus to implement the method. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium.

In the above description, it is assumed that the mobile communication terminal is a SIM card replacement type, and the user installs the second region SIM card in the first region mobile communication terminal. However, in some cases, the first region mobile communication terminal may not be replaced with the SIM card, or the second region mobile communication terminal may be used when the SIM card is not sold separately in the second region.

In this case, by downloading and installing the domestic and overseas call-out service dedicated application according to an embodiment of the present invention on the second-region mobile communication terminal or by installing an additional device embedded with a program dedicated to the call-in / out-of-country call-in service on the input / output terminal of the second-area mobile communication terminal. In addition, by checking the local local number system registered in the storage unit of the second area mobile communication terminal, it is possible to recognize the change of the local number system currently used by the service subscriber similarly to the change of the SIM card.

When the dedicated application or the dedicated program recognizes the change of the local numbering system, it extracts the local numbering system information, that is, the second area opening number, and sends it to the service server to request automatic registration. Similarly, the change of local number system is recognized and automatic registration is made so that domestic and overseas call service can be provided normally.

6 is a flowchart illustrating an origination method in a mobile communication terminal according to an embodiment of the present invention. The mobile communication terminal here assumes that the SIM card change confirmation and automatic registration shown in FIG. 4 are completed.

In step S500, the mobile communication terminal 200 attempts a call through a dedicated application or a dedicated program. To this end, the dedicated application may be driven separately or in the background, and the dedicated program may be embedded in an additional device mounted on the mobile communication terminal 200.

In operation S510, the call manager 244 transmits the call request information including the caller information and the receiver information according to the call attempt to the service server 100. Transmission of call request information may be made through a data network such as an IP communication network. The caller information includes one or more of a customer identification code, a first region opening number, a second region opening number, and the receiver information includes a call request number.

In operation S520, the service server 100 extracts caller information included in the call request information and transmits a callback to the mobile communication terminal 200 corresponding to the caller information.

If the caller information is a customer identification code or a first area opening number, a second area opening number corresponding to the same customer identification code or first area opening number is searched in the customer database 110 provided in the service server 100. Using this, callback can be sent to the mobile communication terminal 200. If the caller information is the second area opening number, the caller may be called directly to the mobile communication terminal 200 using the caller information.

In this case, the call manager 244 of the mobile communication terminal 200 automatically receives a callback in step S530. With automatic reception, the user does not have to perform a separate reception procedure, and feels as if he is still in an outgoing state.

In step S540, the service server 100 extracts the receiver information included in the call request information and transmits it to domestic and foreign receivers corresponding to the receiver information. Step S540 is performed at substantially the same time as the callback origination in step S520.

When the call connection in step S520 and the call connection in step S540 are established, it is connected in step S550 to make a call between the caller and the receiver.

7 is a flowchart illustrating a receiving method in a mobile communication terminal according to an embodiment of the present invention. The mobile communication terminal here assumes that the SIM card change confirmation and automatic registration shown in FIG. 4 are completed.

In step S600, the domestic caller attempts to call the first area opening number of the service subscriber.

In step S610, the domestic mobile communication service provider transmits a call connection request to the service server 100 according to the personal number set in the call forwarding with respect to the first area opening number.

In step S620, the service server 100 identifies the service subscriber corresponding to the call request personal number, and retrieves the second area opening number registered for the service subscriber.

In step S630, the service server 100 transmits a call connection request to the retrieved second area opening number, and the call of the domestic caller is routed to the mobile communication terminal 200 of the service subscriber identified by the second area opening number. Connect the call in S640.

8 is a diagram illustrating a driving screen of a dedicated application for providing domestic and overseas call origination services according to an embodiment of the present invention.

Referring to FIG. 8, the display screen includes a subscriber information display unit 710, a service use display unit 720, and a service registration result display unit 730.

The subscriber information display unit 710 transmits the customer information such as the selection of the country where the service subscriber is currently located, the local opening number opened by the service subscriber, the name of the service subscriber, and the opening address of the first region (Korea) of the service subscriber. The necessary information is displayed. The local opening number may be automatically input in accordance with the above-described automatic registration process.

The service use display unit 720 displays the registration and use, cancellation, suspension of use, password, and the like.

The service registration result display unit 730 displays the processing result according to the request for automatic registration of incoming and outgoing services at home and abroad, and if successful, the local opening number registered in the service server may be displayed together with the automatic registration notification message.
