Description

Roaming method using call forwarding service and computer readable recording medium

The present invention relates to a roaming method and a computer-readable recording medium using a call forwarding service, and more particularly, by supporting a call forwarding to a phone number set using a call forwarding service registered for each carrier, it is free in domestic as well as overseas. A roaming method and a computer-readable recording medium using a call forwarding service supporting roaming are provided.

With the recent development of transportation and communication technology, not only domestic but also foreign countries have entered the daily life zone, and with the spread of social networks, overseas exchanges have increased rapidly. In particular, in the past, overseas roaming services and international call charges were incurred when leaving the country, but as roaming services became popular, the general public began to use overseas roaming services. Nowadays, carriers provide automatic roaming services, so you can receive automatic roaming services when you leave the country without applying for a separate roaming service.

However, since international call charges are still very expensive, even though roaming services are used, most of them refrain from making international calls. Therefore, the call fee must be reduced from the roaming service user's point of view, thereby reducing the user's cost burden and increasing the international call utilization rate through the roaming service.

In response to this problem, Korean Patent Application Publication No. 10-2008-0083549 discloses a mobile communication roaming system using the Internet phone and a service method thereof (hereinafter referred to as a 'prior art'). A technology for lowering roaming costs by enabling forwarding of a subscriber to a telephone number corresponding to an ID has been disclosed. However, the invention of the prior art relates to a technology for connecting a telephone to a separate call setup telephone in addition to the reception telephone possessed by the user, and to use a foreign telephone or wireless telephone instead of using the reception telephone possessed by the user (eg, a smartphone). There is a disadvantage to use.

An object of the present invention is to provide a roaming method using a call forwarding service and a computer readable recording medium for solving the above problems.

A first aspect of the present invention provides a roaming method using a call forwarding service using a roaming application executed in a client terminal, the method comprising: analyzing a communication company to which the client terminal is subscribed; Confirming whether to subscribe to a call forwarding service provided by the communication company; Checking a call forwarding unique number provided from a management server when registering to the call forwarding service and registering the call forwarding unique number with the management server; And it proposes a roaming method comprising the step of executing a call test for the forwarding unique number. In the registering step, the call forwarding unique number is stored in the management server as a call forwarding target number for the telephone number of the client terminal, and the step of executing the call test is a call signal from the client terminal to a call server. And transmitting a call to the management server when the call server normally receives the call signal.

A second aspect of the invention is a computer readable recording medium operating on a client terminal and recording a roaming application encoded with a computer program, wherein the program is operated by the data processing apparatus when executed by the data processing apparatus. Instructions for causing a network to be executed, the operation comprising: analyzing a telecommunication company with which the client terminal is subscribed; Confirming whether to subscribe to a call forwarding service provided by the communication company; Checking a call forwarding unique number provided from a management server when registering to the call forwarding service and registering the call forwarding unique number with the management server; And executing a call test for the call forwarding unique number, wherein in the registering step, the call forwarding unique number is stored in the management server as a call forwarding target number for the telephone number of the client terminal. The performing of the call test may include transmitting a call signal from the client terminal to a call server, and receiving a call to the management server when the call server normally receives the call signal.

Accordingly, a call connection to the customer center or an application of the communication company can be executed.

The step of registering in the management server includes an automatic registration method and a manual registration method, and if the automatic registration method is selected, automatically executes and registers a predefined registration method according to the analyzed carrier, the manual registration method is selected In this case, one or more registration methods are displayed on the roaming application, and the selected registration method is executed according to a user's selection. The one or more registration methods provide connection to a customer center, execution of a communication company application, and guidance of predefined registration methods for each communication company. It may include.

Call forwarding unique number is an Internet telephone number using Voice over Internet Protocol (VoIP) or mobile-Voice over Internet Protocol (m-VoIP).

When the call forwarding unique number is registered correctly, when the user of the client terminal selects a dial menu for dialing and inputs a first phone number, it is determined whether the country where the inputted first phone number is registered is a free call destination country. step; And performing a call connection when the country in which the first phone number is registered corresponds to the toll-free country, and executing an international calling application when the country is not the toll-free country. Is one or more countries selected by the management server, the international telephone application may be an international telephone application that supports data calls using the Internet network provided by the management server. If the international call application is not installed, the user can move to the installation guide screen or the download screen.

The execution of the call test may include: checking whether the management server is a customer using a CID (Client ID) of the incoming call signal, and transmitting a registration success signal to the client terminal if the customer is confirmed as a customer. It may further include. When the call signal is not normally received to the management server within a predetermined time, a call failure may be notified to the client terminal using an Automatic Response System (ARS).

The present invention can realize a cheap and wide range roaming service through the function of assigning and forwarding a phone number (VoIP or m-VoIP) using the Internet network. When using the roaming application of the present invention, by using the call forwarding function but not receiving by a separate phone, the user does not need to have a separate overseas phone by implementing a call to a terminal possessed by the user.

In addition, by implementing a roaming service in conjunction with a communication company, it is possible to minimize the effort of the user manually input, and to enable automatic registration from call forwarding to roaming to maximize the user's convenience.

In addition to the above, the client terminal 10 may include various modules necessary for general terminal operation and execution of an application, and detailed descriptions of specific modules will be omitted herein.

As an embodiment, the client terminal 10 of the present invention may download a roaming application provided by the management server 20 of the present invention through an application store (for example, an app store, a Google store, etc.). As another example, the roaming application may be downloaded and installed through a push from the management server 20 through an advertisement, a search result, or a web page.

The management server 20 of the present invention is a server for developing, managing and supporting a roaming application in order to provide a roaming method using a call forwarding service to a user, and roaming through a network when the roaming application is executed in the client terminal 10. In addition to supporting the running and progressing of the application, it assigns a unique number necessary for roaming service using call forwarding and manages the unique number. The management server 20 may operate in conjunction with the call server 30 required for the call test, and may support roaming services in conjunction with the communication company server 20.

The call server 30 delivers a call signal to the management server 30 when a call is received from the client terminal 10 during a call test in an embodiment of the present invention, and when a call is not received, a call is impossible. Can send a signal. In one embodiment, the call server 30 may be operated in an integrated form within the management server 20.

The telecommunication company server 40 of the present invention is a server that supports a call forwarding function for a user who subscribes to the service by operating a call forwarding service. Call forwarding service can be operated separately for each telecommunication company, and it supports manual and automatic registration. As an embodiment, the communication company server 40 of the present invention may support the automatic registration method of the call forwarding service in association with the management server 20.

As such, in the roaming method of the present invention, a management server 20, a communication company server 40, and a call server 30 that provide and manage a roaming application interwork with each other, thereby allowing the client terminal 10 to use a cheap and convenient roaming service. Can support In one embodiment, by using the call forwarding service provided by the communication company server 40, by operating the call forwarding to the unique number assigned by the management server 20, the present invention supports the call to the forwarded unique number Through this, it is possible to reduce international call charges.

2 is a flowchart illustrating a roaming method using a call forwarding service according to an embodiment of the present invention. The roaming method of the present invention may be implemented by executing a roaming application installed in the client terminal 10. As described above, the roaming application is operable in conjunction with the management server 20. The order of the steps described below does not necessarily have to be in accordance with the order of the present embodiment, but may be implemented simultaneously or by changing the order.

First, when the roaming application is executed on the client terminal 10, whether to receive a push notification from the management server 20 may be input in the initial execution step. Approval of the push notification may be selected at an initial execution stage or may be set manually by the user in the setting menu. Optionally, the step of confirming whether the push is approved when the application is executed may be omitted.

Next, the roaming method of the present invention analyzes the mobile operator subscribed to the user (step 210). In general, a call forwarding service requires an analysis of a communication service provider since the registration method, call charge, number type, and setting method are all different for each communication service provider. In an embodiment, step 210 may be implemented to analyze a mobile service provider that is automatically subscribed through a roaming application, or in another embodiment, to allow a user to manually select a mobile service provider that has subscribed.

The roaming method of the present invention may post a tutorial to explain how to use the roaming application (step 220). This step may be set to be published only at the first execution, and may be set not to be published at the second execution. The tutorial may be published in a pop-up form or in a screen switching format, or may be automatically guided for a predetermined time (automatic page switching), or implemented to be viewed by the user while turning the page directly. For example, the roaming method of the present invention can be posted by dividing into 'when the current location is domestic' and 'when the current location is overseas'. The publication page of the tutorial may include not only text but also various multimedia means such as images, videos, and music.

Optionally, the present invention may post a screen asking whether the user agrees to the terms of use, and determine whether to proceed with the next step according to whether the user agrees.

In one embodiment, if the user agrees to the terms of use of the roaming application, the user undergoes an SMS authentication step by inputting a phone number (steps 230 and 232). Step 230 can also be performed only once during the first run. When the user enters a phone number and requests an authentication number from the management server 20, an authentication letter sending guide window (for example, a pop-up window) appears, and the screen switches to the authentication number input window. The user may recognize the authentication number included in the authentication character transmitted from the management server 20 to the client terminal 10 and input the authentication number into the authentication number input window. Like the general authentication method, the authentication number may be a one-time number valid for a certain time, may guide re-authentication after a certain time. The authentication letter may be transmitted in an SMS manner including an authentication number. Also, in step 230, when entering a phone number, a country to which a phone number is subscribed may be selected. For example, when a user clicks a country selection (eg, a flag image) in a phone number entry window, the entire country is displayed and implemented to allow the user to select a particular country.

If authentication is successful, the emergency notification may be displayed in a full screen pop-up (step 240). For example, the display may be implemented only when there is an emergency notification. If the emergency notification does not exist, step 240 may be omitted. If the authentication fails, the retry guide window may pop up, and may be switched to the SMS authentication guide page. In addition, after the authentication is completed, a confirmation message may be popped up asking whether the roaming application of the present invention agrees to interwork with another application (eg, a contact, a call module, etc.) and determine whether to proceed according to the user's selection. Can be.

When the setup process according to the initial execution (eg, steps 210 to 240) is completed, the main menu is displayed. The main menu of the present invention may include a dial menu for executing a call connection, a call list menu for providing a call list, a usage menu for a tutorial, and a menu for connecting a projection call center. In addition, it is possible to post a button for selecting whether to activate or deactivate the roaming service provided by the present invention. If the user selects activation, the roaming service provided by the present invention can be implemented to be executable. The main menu of the roaming application of the present invention will be described in more detail with reference to FIG. 7.

If the user activates the use of the roaming service in the main menu, it may be checked whether the roaming service is paid (step 260). The roaming service of the present invention can realize free international calls by implementing an international phone call fee even when using overseas roaming through a method of forwarding calls to an Internet phone number. As a minimum usage fee for such a service, it may be required to pay a predetermined amount (e.g., one week, one month, one year). In operation 260, a payment amount guide and a coupon input may be displayed and payment may be made according to a user's selection. If the user fails to complete the payment or fails, the user may perform the payment guide again and proceed with the payment process (step 262).

The present invention checks whether or not to subscribe to the call forwarding service provided by each carrier (step 270). The roaming method proposed by the present invention is a roaming service using a call forwarding service. Therefore, the roaming method proposed by the present invention should check whether a call forwarding service provided by each carrier is subscribed, and if not, it may guide a subscription method and a fee for each carrier ( Step 272). The step of confirming whether or not to subscribe to the call forwarding service will be described in more detail with reference to FIGS. 5A and 5B.

If the user is subscribed to the call forwarding service, the user switches to the incoming call registration screen (step 280). The called phone number can automatically register a number automatically assigned by the management server 20, and can be implemented to allow a user to manually register. For example, in the case of a paid service, a unique number may be automatically assigned to a user in the management server 20 at the time of payment, and in the case of using a free service, a unique number may be provided when a call forwarding attempt is performed by a roaming application. have. The management server 20 assigns an incoming phone number or performs a function of managing registered incoming phone numbers. The management server 20 automatically assigns a user unique ID when the roaming application is installed. The management server 20 may store and manage a call forwarding unique number by matching the unique ID. The incoming telephone number of the present invention is a VoIP (Internet Phone) or m-VoIP (Mobile Internet Phone) number for making a voice call using the Internet network. m-VoIP refers to a technology (eg, Skype) that allows users to make Internet calls with a mobile phone using a wireless mobile Internet such as Wi-Fi (Wi-Fi) or 3G network. Although the transmission speed of m-VoIP is slower than VoIP, it has the advantage that the utilization is very high as the smart phone becomes popular. The registration method of the incoming telephone number will be described in more detail with reference to FIG. 6.

When the incoming phone number registration is completed, a manual call test is performed (step 290). For example, when the user presses the call test button, the user may notify a message that the user is normally connected or failed to connect through the ARS guide. If the connection is successful, it is implemented so that the user can check the pop-up message after the call ends. If the connection fails, in addition to the ARS guidance, a failure message may be popped up or a retry guidance may be displayed (step 292). In one embodiment, the call test may be implemented to give a valid time to the call signal sent from the client terminal 10 to the management server 20, and to retry the call test when the valid time has elapsed. The call test method will be described in more detail later with reference to FIG. 7.

When the call test is completed, it is determined that the setting for using the roaming service of the present invention is completed (step 296). When the setting is completed, the user can be informed of the setting completion or automatically switched to the main menu. For example, when the setting is completed, a message indicating that registration is normally performed may be displayed together with a notice regarding precautions. In addition, a menu or icon for confirming whether the user is normally connected after the initial connection may be displayed to provide the user with a real-time connection status. In addition, when the user restarts the roaming application after the end of the roaming application, it may be implemented to display the current connection status and instructions (for example, display in a speech bubble window on the main menu screen).

In the roaming application of the present invention, when the roaming service is turned off, in addition to simply deactivating the roaming service, an incoming phone number termination guide can be displayed. Can be. The service provider can be guided according to the service provider's termination method, and can automatically or manually connect to each service provider's customer center. In one embodiment, when the management server 20 in conjunction with the communication company server 40, the user clicks the release button, by implementing the release signal to be sent to the communication company server 40 through the management server 20, automatic termination It can be implemented to make it possible.

As such, the present invention can realize a cheap and extensive roaming service through the function of the call forwarding to the telephone number using the Internet network. In addition, by implementing a roaming service in conjunction with a carrier, it is possible to maximize the user's convenience by minimizing the effort of manually inputting by the user and enabling automatic registration. That is, the present invention can provide a roaming service having an effect of user convenience and cost reduction.

3 is a flowchart illustrating a call connection method among roaming methods using a call forwarding service according to an embodiment of the present invention. On the main menu provided by the roaming application, the user may select a 'dial' menu (step 350, 360).

When the user presses the dial menu, the dial (numeric pad) can be displayed or a contact list can be displayed to enter a dialed telephone number. The present invention is implemented to display a dial so that when a user enters a phone number, the user can select a country to call. For example, by displaying the world flag and the country name, the user can select the country to connect to the country even if they do not know the country code of each country. If the user selects a specific country and attempts to call by entering a phone number, the roaming application may automatically enter the country code in front of the entered phone number and proceed with the call connection.

As another example, a user may attempt to connect a call by selecting a person to be called by a contact or a call list. If you select a specific list, the call is automatically connected.

In operation 370, the present invention determines whether the user is a free call destination country for the phone number input or selected by the user. For example, the toll free country may be a country having a fare of less than 50 won (eg, India, Canada, the United States, China, Thailand, Hong Kong, Malaysia, Vietnam, Indonesia). The toll-free country can change the country according to the determination of the roaming service usage fee of the present invention. In the case of a toll-free country, call connection is attempted (step 372).

If the country is not a free call destination, it is determined whether the global app is installed (step 380). The 'global app' of the present invention is an international telephone application developed and managed by the management server 20, and is an mVoIP international telephone application that supports data calls using an internet network (for example, WiFi). The global app may be free or paid depending on the country, and may be induced to the user in a country that is not supported through the roaming application of the present invention. If a global app is not installed, display the installation instructions (step 382). If the global app is installed, the global app is automatically executed to perform a call connection (steps 390 and 392). In one embodiment, when the user agrees and sets the roaming application and the global app in advance, the call may be automatically made through the global app when the user is not the target country of the free call after attempting the call with the roaming application. Alternatively, by setting priorities for the execution of two applications, a call may be attempted through an application set according to a user's preference, but a call may be automatically executed through a next-order application when connection is not possible.

As such, the roaming method of the present invention provides a free call to the roaming application, but if it is not the target country of the free call, it is switched to a general phone call to prevent excessive call charges, thereby inducing execution of a global app. This has the advantage of providing an alternative to the user. The global app allows you to make free calls or make calls that are much cheaper than regular international calls, so you can offer users cheap and extensive international calls.

4 is a screen screen illustrating a main menu screen and a roaming service start method of a roaming method using a call forwarding service according to an embodiment of the present invention. 410 is an example of a splash screen (start screen) when the roaming application is executed.

When execution and loading of the roaming application is completed, the main menu screen may be displayed (420). Initially, the roaming service can be started from the main menu as OFF. The main menu screen 420 of the present invention may include a click area 422 and a menu area 424. The click area displays the ON / OFF state of the roaming service and the service subscription progress state (step state). In the OFF state, the menu screen may be displayed in a color different from the ON state (for example, black color) as shown in the figure so that the user can feel the OFF state of the roaming service. In the OFF state, the menu function is not deactivated, and all or some menus (eg, dials, settings) can be activated. In the present embodiment, the menu area 424 includes a dial, a call list, a usage, and a call center connection menu, but may further include or omit other menus.

When the user turns on the roaming service, the screen color may be switched (430), and the current step may be displayed in the click area (432). For example, joining a call forwarding service (step1), registering the forwarding unique number (step2), and testing the call (step3) steps, the next step is automatically activated when the previous step is completed, click area 423 ) May be displayed. When all the steps are completed, the screen is switched to the ON screen (440, 442). These steps may be executed for registration during initial execution, or may be displayed when the call forwarding number is not connected, or may be immediately switched to an ON state when the connection is normally established.

In addition, the menu area configuration of the OFF state, each step progress state, and the ON state can be displayed differently. For example, in the OFF state 420, a dial, a call list, a usage, and a projection call center connection menu may be included, but in the step1 state 430, a menu required for a corresponding step may be configured including a payment menu.

In addition to the click area and the menu area of the main menu area shown in this drawing, it may include a separate advertising area or may further include a shortcut menu, a banner, and the like.

5A and 5B are screen screens illustrating a method for confirming whether or not a call forwarding service is registered according to an embodiment of the present invention. Call forwarding services can be subscribed through the carrier, so that each carrier can be guided through the analysis of the carrier. For example, if the user is an A telecom subscriber, it may be determined whether the user has subscribed to the A telecom call forwarding service in step 1 (510). In addition, a simple guide to the call forwarding service is displayed together to help users understand.

If the subscriber does not subscribe to the forwarding service, the call forwarding service subscription guide of the carrier (520). The service provider charges the service provider and may include a customer center connection button (522). If you click the Connect Customer Center button, you can call the customer service center of the corresponding carrier. If the user clicks the 'More' button to view the detailed price information, detailed price information and service description can be viewed (530 and 532).

Although not shown in the figure, if the carrier application is installed, including a button to apply through the carrier application, it can be implemented to run and register the carrier application. In addition, through the interworking of the management server 20 and the communication company server 40, it can be implemented so that it can be directly subscribed on the roaming application of the present invention, without going through the customer service center or communication company application of the communication company.

Referring to Figure 5b, if the user is subscribed to the call forwarding service, if the user confirms the subscription (click 'Yes' button), the next step is to switch to the step of registering the forwarding unique number (540, 542).

Fig. 6 is a screen screen showing a method for registering an incoming call number according to an embodiment of the present invention. In the step of registering the forwarding unique number may guide automatic registration and manual registration (610). For example, by displaying the call forwarding unique number assigned by the customer registered carrier and the management server 20 of the present invention to allow the customer to confirm, and proceeds to 'automatic registration' or 'manual registration'. As described above, when a communication company application is installed, the application may be displayed to be applied to the communication company app, and may be implemented to automatically switch to the communication company app when selected.

If the automatic registration is selected, the client terminal 10 may transmit the automatic registration signal to the management server 20 to register the management server 20. If you proceed with the automatic registration, go to screen 630, and the call forwarding for the call forwarding. Ask the user to check whether the call is sent before calling automatically. If a beep sound is sent to inform the normal registration once again check whether the unique number registration (640) and proceeds to step3.

If the manual registration is selected, a method of registering a number for each carrier may be guided on the roaming application. Manual registration can be done by calling the customer center and registering through an agent, using a mobile operator application, or using a registration method specified by a mobile operator (for example, pressing 71, pressing a call forwarding desired number, and then using a call button). There are ways. In operation 620, the user may be notified of each method and displayed to connect to a customer center or an application. When the registration is completed, the screen proceeds to the screen 630 to perform call forwarding for call forwarding (630) and checks whether or not normal registration (640).

Such call forwarding unique number registration may be manually registered through a user's operation according to the guide, but may be implemented to automatically execute all steps. For example, when a user clicks on the automatic forwarding after confirming the forwarding unique number, the user can automatically register 71, the forwarding unique number, and the call button through the call module.

7 is a screen screen showing a call test method according to an embodiment of the present invention. The client terminal 10 performs a call test by clicking the call test button on the roaming application or by clicking step 3 of the click area of the main menu (710). As shown on the screen 710, a simple guide message for the call test method may be displayed. The roaming application may be implemented to automatically send a call to the call server 30 using the call module of the client terminal 10 when the call test button is clicked.

When the call is normally received by the call server 30 and delivered to the management server 20, a message indicating that the call is normally connected is displayed as shown on the screen 730, and when OK is pressed, the click area of the main menu screen is switched to the ON state. .

If the call test fails, the user can be guided to run the call test again as shown on the screen 720. The call test of the present invention transmits a call signal for a predetermined time to receive a call signal from the call server 30, and when a predetermined time elapses, guides the call signal to be sent again. If the call is not normally received, the management server 20 may enter the call to the client terminal 10, and may prompt the ARS to reconfirm the message along with a message that the call forwarding unique number is not normally set. If the call test is not completed, the click area of the main menu is implemented to remain displayed in step3.

8 is a flowchart illustrating a call test method according to an embodiment of the present invention. When the call test is selected on the roaming application executed in the client terminal 10 (step 810), the client terminal 10 requests the call test to the management server 20 (step 820). The management server 20 receives the call to the client through the call server 30 (step 830). At this time, the outgoing number refers to the number authenticated by the user through the SMS authentication step at the time of initial registration. When the call server 30 attempts to call the authenticated number of the client terminal 10, the call comes in the number where the call forwarding is registered (that is, the call forwarding unique number set in the call server 30).

When a call is received with a call forwarding unique number set in the call server 30, the call server 30 confirms that the call is normally received, and transmits a call test success signal (or message) to the management server 20 (840). , 850 steps). When the management server 20 receives the call test success signal, the management server 20 transmits a registration success signal to the client terminal 10 to complete the call test (step 860). For example, the management server 20 may transmit a registration success signal to the client terminal 10 and may pop a success message or transmit a specific call tone through the roaming application.

On the other hand, if the call is not received by the call forwarding unique number set in the call server 30, the call server 30 transmits a call test failure signal (coming message) to the management server 20 (step 870). When the management server 20 receives the call test failure signal, the management server 20 may transmit the registration failure signal to the client terminal 10 in one embodiment or the ARS failure guidance message in another embodiment (step 880).

Through this call test step, the user can check again that the registration of the forwarding unique number has been performed normally. In this embodiment, the call server 30 and the management server 20 has been described as operating in conjunction, but the management server 20 is implemented in an integrated form with the call server 30, receives the call signal and unique number It can be implemented to register.
