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

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

The management server 20 of the present invention is a server that develops, manages and supports a roaming application in order to provide a roaming method using a call forwarding service to a user. The server 20 is a server for roaming through a network Not only supports the operation and progress of the application but also assigns a unique number necessary for roaming service using call forwarding and manages the unique number. The management server 20 can operate in cooperation with the call server 30 required for the call test and can support the roaming service in cooperation with the communication company server 20. [

The call server 30 transmits a call signal to the management server 30 when a call is received from the client terminal 10 during a call test according to an embodiment of the present invention. If the call server 30 fails to receive a normal call, Signal can be transmitted. In one embodiment, the call server 30 may be operated in an integrated manner within the management server 20. [

The communication company server 40 of the present invention manages a call forwarding service and supports a call forwarding function for a user subscribed to the service. Each communication company can operate the call forwarding service separately and supports manual and automatic registration. In one embodiment, the communication company server 40 of the present invention can support the automatic registration method of the call forwarding service in cooperation with the management server 20. [

As described above, the roaming method of the present invention is a roaming method in which a management server 20, a communication company server 40, and a call server 30, which provide and manage a roaming application, . As an embodiment, by using the call forwarding service provided by the communication company server 40 so as to enable call forwarding to a unique number assigned by the management server 20, Which can 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 can be implemented through execution of 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 each step to be described later is not necessarily according to the order of this embodiment, and can be implemented at the same time or by changing the order.

First, when the roaming application is executed on the client terminal 10, it can be input whether or not to approve the push notification from the management server 20 in the initial execution step. Whether or not push notifications are approved can be selected at the initial execution stage or directly set by the user in the setup menu. Optionally, the step of confirming whether or not the push has been granted upon execution of the application may be omitted.

Next, the roaming method of the present invention analyzes a communication company to which the user subscribes (Step 210). Generally, the call forwarding service requires analysis by the communication company because the registration method, the call charge, the number type, and the setting method are different for each communication company. In one embodiment, step 210 may be implemented to automatically analyze the subscribed subscribers through the roaming application, or, in another embodiment, to manually select subscribed subscribers.

The roaming method of the present invention may publish a tutorial to illustrate the use of the roaming application (step 220). This step can be set to be posted only at the time of the first execution, and can be set not to be posted at the second execution time. The tutorial can be posted in a pop-up or transitional format, automatically guided for a period of time (auto-page switching), or viewed by the user directly over the page. For example, the method of using the roaming method of the present invention can be divided into 'when the current location is domestic' and 'when the current location is overseas'. The publishing page of the tutorial can include not only text, but also various multimedia means such as images, movies, and music.

Alternatively, the present invention may post a screen asking whether or not to agree to the Terms of Use, and may decide to proceed with the next step according to the user's consent.

In one embodiment, if the user agrees to the terms of use of the roaming application, the SMS authentication step is performed through inputting the telephone number (steps 230 and 232). Step 230 can be performed only once during the initial execution. When the user inputs a telephone number and requests the management server 20 for an authentication number, an authentication letter forwarding window (for example, a pop-up window) is displayed and the window is changed to an authentication number input window. The user can 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 can be a one-time number valid for a certain period of time, and can guide re-authentication when a predetermined time elapses. The authentication character may be transmitted by an SMS method including an authentication number. Also, in step 230, when entering the telephone number, the country where the telephone number is registered can be selected. For example, when a user clicks a country selection (e.g., a flag image) in the telephone number input window, the entire country is displayed and the user is made to select a specific country.

If the authentication is successful, the emergency notice can be displayed as a full screen popup (step 240). For example, it can be implemented to display only the emergency notification, and if there is no emergency notification, step 240 can be omitted. If the authentication fails, the retry guide window pops up and can be switched to the SMS authentication guidance page. Optionally, after completing the authentication, a confirmation message may be popped up asking whether the roaming application of the present invention agrees with other applications (e.g., contacts, currency modules, etc.) .

When the setting process according to the initial execution (e.g., steps 210 to 240) is completed, the main menu is displayed. The main menu of the present invention may consist of a dial menu for making 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, a button for selecting whether to activate or deactivate the roaming service provided by the present invention can be posted. When 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.

When the user activates the use of the roaming service in the main menu, it is possible to confirm whether or not the roaming service is settled (step 260). The roaming service of the present invention can realize a free international call by implementing the international roaming service so that the roaming service does not occur even when the roaming service is performed through the call forwarding method to the Internet telephone number. You may be required to pay a certain amount of money (such as a bar, a week, a month, or a year) as the minimum usage fee for these services. In step 260, the payment amount guidance and coupon input are displayed so that payment can be performed according to the user's selection. If the user fails to complete the payment or fails, the user can perform the payment guidance again and proceed with the payment process (step 262).

The present invention confirms whether or not the call forwarding service provided by each communication company is subscribed (step 270). The roaming method proposed by the present invention is a roaming service using a call forwarding service, and it is necessary to confirm whether or not to join the call forwarding service provided by each communication company, 272). The step of confirming whether or not to join the call forwarding service will be described in more detail with reference to FIGS. 5 (a) and 5 (b), which will be described later.

If the user is subscribed to the call forwarding service, the number change screen is displayed (step 280). The incoming telephone number can be automatically registered in the management server 20 automatically, and can be manually registered by the user. For example, in the case of a paid service, a unique number may be automatically assigned to the user in the management server 20 at the time of payment, and when the free service is used, have. The management server 20 performs a function of giving an incoming telephone number or managing the registered incoming telephone numbers. The management server 20 automatically assigns a unique ID to the management server 20 when the roaming application is installed. The management server 20 can store and manage the unique ID with matching the ID number. The called telephone number of the present invention is VoIP (Internet telephone) or m-VoIP (Mobile Internet Telephone) number for performing voice communication using the Internet network. m-VoIP refers to a technology (eg, Skype) capable of making Internet calls to a mobile phone using a wireless mobile Internet such as a Wi-Fi (Wi-Fi) or 3G network. Although the transmission speed of m-VoIP is slower than VoIP, it has the advantage of being highly utilized as smartphones become popular. The registration method of the incoming telephone number will be described in more detail with reference to FIG.

When the registration of the incoming telephone number is completed, the manual call test is executed (Step 290). For example, if the user presses the call test button, the call can be normally connected through ARS guidance or a message indicating that the connection has failed can be notified. If the connection is normally established, the connection success message is popped up after the call is terminated and the user is able to confirm it. If the connection fails, a failure message can be popped up or a retry guide can be displayed in addition to the ARS guidance (step 292). In one embodiment, the call test may be implemented such that the client terminal 10 gives a valid time to the call signal sent to the management server 20, and retries the call test when the valid time has elapsed. The call test method will be described in more detail with reference to FIG. 7 to be described later.

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 completion of the setting or can automatically switch to the main menu. For example, when the setting is completed, a message informing that it has been registered normally can be displayed along with a guide on the caution. In addition, a menu or an icon for confirming whether or not the user is normally connected even after the initial connection can be displayed, so that the user can be provided to check the real-time connection status. Further, when the user re-runs after the end of the roaming application, the present connection state and the guidance items can be displayed (for example, displayed as a speech balloon 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, it is possible to display the incoming phone number cancellation guidance, and if the user selects to cancel, . According to the method of cancellation according to the telecommunication company, the telecommunication company can automatically or manually connect to the customer center of each telecommunication company and guide the other telecommunication terminating method according to the domestic or overseas stay. In one embodiment, when the management server 20 cooperates with the communication company server 40 and the user clicks the cancel button, the control server 20 implements a cancel signal to be sent to the communication company server 40, .

As described above, the present invention can realize an inexpensive and extensive roaming service through the function of redirecting to a telephone number using the Internet network. In addition, by implementing a roaming service in cooperation with a communication company, it is possible to minimize the labor of manual input by the user and to implement automatic registration so as to maximize user convenience. That is, the present invention can provide a roaming service that has a user convenience and a cost reduction effect.

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

When the user presses the dial menu, the dial (numeric pad) can be displayed or the contact list can be displayed so that the telephone number of the call connection can be inputted. The present invention is implemented so that when a user inputs a telephone number, a dial is displayed to select a country to dial. For example, by displaying the world flag and the country name, the user is provided with a country selection, even if the user does not know the country number of each country, so that the country can be connected to the call. When a user selects a specific country and then enters a telephone number, the roaming application automatically adds the country code to the entered telephone number to proceed with the call connection.

As another example, the user may attempt to connect a call by selecting the person to call from the contact or call list. When you select a specific list (a specific person), the call connection is automatically performed.

In step 370, the present invention determines whether the telephone number is a free call destination for the telephone number entered or selected by the user. For example, a free call destination may be a country with a charge of less than 50 yuan (eg, India, Canada, USA, China, Thailand, Hong Kong, Malaysia, Vietnam, Indonesia). The free call target station can change the target station according to the determination of the roaming service usage fee of the present invention. If it is a free call destination, the call connection is attempted (step 372).

If it is not a free call destination, it is determined whether a global app is installed (step 380). The 'global application' of the present invention is an international phone application developed and managed by the management server 20, and is an mVoIP international phone application supporting data communication using an Internet network (for example, WiFi). Global apps can be free or paid for, depending on the country, and can be triggered to users in countries that are not supported by the roaming application of the present invention. If the global app is not installed, the installation guide is displayed (step 382). If the global app is installed, the global app is automatically executed to perform the call connection (steps 390 and 392). In one embodiment, when the user agrees and sets the interworking of the roaming application and the global application in advance, the call may be automatically performed through the global application when the roaming application is not a free call destination after the call attempt. Alternatively, a priority may be set for execution of the two applications, and a call may be attempted through an application set according to the preference of the user, and the call may be automatically executed through the inaccessible subordinate application.

As described above, the roaming method of the present invention provides a roaming application with a free call, and when the mobile station is not a free-to-call destination, it induces the execution of a global application in order to prevent an excessive call fee from being generated There is an advantage to providing an alternative to the user. Global apps can offer free and inexpensive international calls to users because they can make free calls or use less expensive calls than regular international calls.

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

When the execution and loading of the roaming application is completed, the main menu screen can be displayed (420). Initially, you can start roaming service off from the main menu. The main menu screen 420 of the present invention may include a click area 422 and a menu area 424. The click area indicates the ON / OFF state of the roaming service and the service joining progress state (step state). In the OFF state, the user can display the menu screen in a different color (for example, black color) from the ON state as shown in the drawing so that the user can intuitively understand the state of turning off the roaming service. In the OFF state, the menu function is not disabled, and all or some menus (e.g., dial, setting) may be activated. In the present embodiment, the menu area 424 includes a dial, a call list, a usage method, and a menu for connecting a projection call center, but may further include or omit other menus.

If the user switches the roaming service to ON, the color of the screen may be switched 430 and the current step may be marked 432 in the click area. For example, it includes steps of subscribing to a call forwarding service (step 1), registering an idle number (step 2), and testing a call (step 3). When the previous step is completed, the next step is automatically activated, ), The current step 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 at the time of initial execution, or may be displayed when the call forwarding number is not connected, and may be switched from the OFF state to the ON state if the connection is normally established.

It is also possible to display the menu area configuration in the OFF state, each step progress state, and the ON state differently. For example, in the OFF state 420, a menu for dialing, a call list, a usage method, and a connection to the projection call center may be included. In the step 1 state 430, a menu for settlement may be included.

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

5A and 5B are screen screens illustrating a method of confirming whether or not to join the call forwarding service according to an embodiment of the present invention. Since the call forwarding service can be subscribed through the communication company, it is possible to provide guidance for each communication carrier through analysis of the communication carrier. For example, if the user is an A telecom subscriber, it can be determined in step 1 whether the user has subscribed to the A telecom call forwarding service (510). It also displays a brief guide to other call forwarding services to help users understand.

If the subscriber does not subscribe to the ad-hoc switching service, the subscriber informs the subscriber of the subscriber's subscription service (520). And may include a customer center connection button (522). If you click the Connect Customer Center button, you can connect to the customer service center of the correspondent. If you click on the 'More' button to view the details of the service charge details, you can see the detailed fare and service description (530, 532).

Although not shown in the figure, when a communication company application is installed, the communication company application can be implemented and registered including a button for applying through a communication company application. Further, the management server 20 and the communication company server 40 can be linked to each other without intervention of the customer center or the communication company application of the communication company.

Referring to FIG. 5B, if the subscriber is subscribed to the call forwarding service, the subscriber confirms the subscription (click on the 'Yes' button) and switches to the next step of registering the call forwarding unique number 540 and 542.

FIG. 6 is a screen screen illustrating a method for registering an incoming telephone number according to an embodiment of the present invention. In the step of registering the call forwarding unique number, automatic registration and manual registration may be guided (610). For example, the customer can identify the call forwarding unique number assigned by the communication company registered by the customer and the management server 20 of the present invention, and proceeds with 'automatic registration' or 'manual registration'. As described above, when a communication company application is installed, it can be displayed so as to be applied to a communication company application, and automatically switched to a communication company application when selected.

When automatic registration is selected, the client terminal 10 can transmit the automatic registration signal to the management server 20 and register the automatic registration signal in the management server 20. If the automatic registration is performed, the screen goes to the 630 screen to make a call for call forwarding. Make sure that the user is calling before sending the call automatically. When a signal indicating normal registration is transmitted, it is confirmed once again whether or not the unique number is registered (640), and the process proceeds to step 3.

When manual registration is selected, the roaming application can guide the method of registering a number for each communication company. A method of manually registering a telephone number is described in detail below. The telephone number is registered in the telephone number of the customer center. The registered telephone number is registered in the register of the communication company (for example, There are ways. On the 620 screen, the user can be guided through each method and displayed to connect to a customer center or application. When the registration is completed, the screen is shifted to the screen 630 to perform call origination switching (630), and it is confirmed whether it is normally registered (640).

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

7 is a screen screen illustrating a call test method according to an embodiment of the present invention. The client terminal 10 proceeds to a call test by clicking a call test button on the roaming application or by clicking step 3 of the click area of the main menu (710). 710 < / RTI > screen, a simple prompt message about the call test method may be displayed. The roaming application can automatically implement 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 to the call server 30 and delivered to the management server 20, a message indicating that the call is normally connected as shown on the screen 730 is displayed, and when the call is confirmed, the click area of the main menu screen is displayed to be turned on .

If the call test fails, guide the call test back to run as shown on screen 720. The call test of the present invention sends a call signal for a predetermined time and receives a call signal from the call server 30. When a predetermined time has elapsed, the call test leads the call signal again. If it is not normally brought in, the management server 20 may enter a call to the client terminal 10 and inform the ARS of a message to confirm that the call forwarding unique number has not been set normally, together with a confirmation message. When the call test is not completed, the click area of the main menu is implemented to be displayed in step 3.

8 is a flowchart showing a call test method according to an embodiment of the present invention. In step 820, the client terminal 10 requests a call test to the management server 20 by selecting a call test on the roaming application executed in the client terminal 10 (step 810). The management server 20 having received the call transmits a call to the client through the call server 30 (step 830). At this time, the calling number refers to the number authenticated by the user through the SMS authentication step in the initial registration. When the call server 30 attempts to make a call to the authenticated number of the client terminal 10, the call comes in with the number registered for call forwarding (that is, the call forwarding unique number set in the call server 30).

When the call is received with the call forwarding unique number set in the call server 30, the call server 30 confirms that the call has been normally received and transmits a call test success signal (or message) to the management server 20 (840 , Step 850). Upon receiving 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, pop up a success message through the roaming application, or transmit a specific call.

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 (message) to the management server 20 in step 870. In step 880, when the management server 20 receives the call test failure signal, it transmits the registration failure signal to the client terminal 10 in one embodiment, or transmits the ARS failure announcement message in another embodiment.

Through such a call test step, the user can again confirm that the registration of the call forwarding unique number has been completed normally. The management server 20 is implemented in a form integrated with the call server 30 to receive the call signal and to receive the unique number As shown in FIG.
