A list of base stations for providing may be stored.

Such data stored in the storage 140 may be deleted, changed, or added according to a user's manipulation.

The control unit 150 may be a process unit that actually operates the operating system. For example, the control unit 150 may be a central processing unit (CPU). When the power of the user terminal 100 is turned on, the controller 150 moves the operating system from the auxiliary storage device of the storage unit 140 to the main storage device, and then boots the operating system. In addition, when there is a request through the input unit 130 of the user, an application for providing a free call service according to an embodiment of the present invention may be loaded and executed from the storage unit 140. Such a free calling service providing method according to an embodiment of the present invention will be described in more detail later.

4 is a flowchart illustrating a method for checking a free call service area in a method of providing a free call service according to an embodiment of the present invention, and FIG. 5 is a current location of a user terminal according to an embodiment of the present invention free of charge. If the location is located in the call service area, it is an exemplary screen showing an identifier for recognizing this through the user terminal.

First, referring to FIG. 4, in order for the user terminal 100 to use a free call service, first, a user recognition authentication of a free call service must be performed.

Therefore, the user terminal 100 requests the authentication of whether or not the service device 200 is subscribed to the free call service in step S405. The authentication request may be made periodically when a user of the user terminal 100 attempts a free call, updates data for a free call service, or periodically. To this end, the user terminal 100 transmits information for identifying a user (eg, subscriber identification information).

In response to the request of the user terminal 100, the service apparatus 200 requests the subscriber authentication apparatus 300 to authenticate whether the user terminal 100 is subscribed to the free calling service in step S410. Then, the subscriber authentication apparatus 300 checks whether the user terminal 100 is subscribed to the free call service through previously stored information.

Thereafter, the subscriber authentication device 300 provides the authentication result to the service device 200 in step S415. Here, the authentication result may be provided in the form of a response message, for example, an ACK or NACK message. In an embodiment of the present invention, it is assumed that the user terminal 100 is subscribed to a free call service and is successfully authenticated. Explain.

Thereafter, the service device 200 receives the base station list from the base station information device 400 in step S420. Here, the base station list may be cell identifier information of the base station in the area providing the free call service. Thereafter, the service device 200 transmits a base station list to the authenticated user terminal 100 in step S425. In an embodiment of the present invention, step S420 in which the service device 200 receives the base station list from the base station information device 400 is illustrated as being performed after step S415, but the base station list may be updated at any time. The service device 200 may receive the base station list periodically or when necessary. Therefore, the base station list transmitted in step S425 is not generated continuously in step S420, and the base station list transmitted in step S425 will be the base station list most recently received and stored by the service apparatus 200. The user terminal 100 that has received the base station list in step S425 stores the received base station list.

Thereafter, the user terminal 100 obtains a cell identifier from its serving base station 500 in step S430. Such a cell identifier may vary depending on the type of radio protocol, but may be received through a specific channel such as a broadcast channel or a synchronization channel, and is a cell identifier of a base station to which it belongs, that is, a serving base station. Although the step S430 is illustrated as being performed after receiving the base station list, the present invention is not limited thereto. For example, a cell identifier of the user terminal 100 may include cell selection / reselection, inter-frequency movement, intra-frequency movement, handover, and the like. It can be performed every time a variable action is taken. Therefore, this step S430 should be understood as an operation of obtaining the cell identifier of the cell to which the current user terminal 100 belongs, and is not related to the order of the other steps.

In step S435, the user terminal 100 determines whether its current location is a free call service area using the base station information and the cell identifier. That is, since the base station information includes a list of base stations within the area providing the free call service, the user terminal 100 determines whether the base station 500 to which the base station 500 belongs to the base station provides the free call service through the obtained cell identifier. As a result, it may be determined whether the current location is a free call service area.

In operation S435, when the serving base station of the user terminal 100 is a base station that provides a free call service, the user terminal 100 may identify an identifier indicating that the user terminal 100 belongs to the free call service area so that the user can easily recognize the user terminal 100. It can be displayed through (100).

That is, as shown in FIG. 5, the user terminal 100 displays a white icon 510 when the current location is not the free call service area (A), or when the current location belongs to the free call service area, It may also be indicated by a red icon 520 so that the user can easily recognize (B).

Through this, the user can easily check whether his current location is available for free call service.

According to an embodiment of the present invention as described above, the user terminal 100 receives a base station list from the service device 200, checks a cell identifier of its serving base station 500, and then the serving base station directly connected to the user terminal 100 receives the base station list. For example, the method of determining whether the base station is located within the area providing the free call service is described as an example. However, the present invention is not limited thereto. The cell identifier of the serving base station is transmitted to the service device 200, and the service device 200 is connected to the base station list. In comparison, it may be determined whether the current location of the user terminal 100 is within the free call service area.

6 is a flowchart illustrating a method for checking a free call service area of a user terminal 100 according to an exemplary embodiment of the present invention. Referring to FIG. 6, as described above, the user terminal 100 makes a free call. In order to use the service, you must first verify that you are subscribed to a free calling service. Therefore, the control unit 150 of the user terminal 100 through the communication unit 110 in step S605 The service device 200 requests an authentication of whether the free call service is subscribed. In this case, the authentication request is performed when the user of the user terminal 100 tries to make a free call through the input unit 130, or when updating data for using a free call service, or periodically requests the authentication as described above. Can be. In the authentication request, information (eg, subscriber identification information, etc.) for identifying a user (ie, a subscriber) of the user terminal 100 may be transmitted together.

As described above, if there is an authentication request, the service device 200 performs authentication of the user terminal 100, and when the user terminal 100 is subscribed to a free call service, the service device 200 transmits base station information. Receives a list of base stations from the device 400 and provides them to the user terminal 100.

Then, the controller 150 of the user terminal 100 may receive a base station list through the communication unit 110 in step S610. Here, the base station list means cell identifier information of the base station in the area providing the free call service.

In addition, the control unit 150 may obtain a cell identifier from the base station 500 to which it is connected in step S615. Such a cell identifier may be received, for example, through a broadcast channel and is a cell identifier of a base station to which it belongs, that is, a serving base station. For example, in the case of LET, an eNodeB ID and a cell number may be used as cell identification information. In LTE, an E-utran Cell ID (ECI) is composed of 28 bits, and "ECI (28) = eNB ID (20) + headquarters division (3) + base station number (15) + cell number (6) + network (2). Is configured as ". Accordingly, the controller 150 may acquire 28 hooks to obtain an eNodeB ID and a cell number where the current user terminal 100 is located by analyzing the preceding 28 digits. In the case of WCDMA, a cell ID having a structure as shown in Table 1 may be used as a cell identifier.

The above-described steps S610 and S615 are described as if the base station list is obtained and then the cell identifier is obtained, but the order of obtaining the base station list and the cell identifier is not limited. As such, after obtaining both the base station list and the cell identifier, the controller 150 determines whether the current location is within the free call service area by using the base station list and the cell identifier in step S620. That is, since the base station list means cell identifier information of the base station in the area providing the free call service, it is checked whether the cell identifier of the base station 500 to which the base station 500 is connected is included in the cell identifier information of the base station list, It may be determined whether the location is an area where free calling service is available.

Thereafter, the controller 150 displays an identifier so that the user can easily recognize whether the current location is within the free call service area in step S625. That is, as shown in FIG. 5, when the current location is not the free call service area, a white icon 510 may be displayed (A), or when the current location is within the free call service area, a red icon 520 may be displayed (B). .

As described above, the user terminal 100 may identify and display whether the current location is within the free call service area, and thus the user may easily identify whether the current location is a free call service area.

Hereinafter, a method of providing a free call service according to an exemplary embodiment of the present invention will be described.

7 is a flowchart illustrating a method for providing a free call service according to a first embodiment of the present invention, and FIG. 8 is a screen example for explaining a method for providing a free call service according to a first embodiment of the present invention. In FIG. 7, a voice call among free call services will be described. However, it will be apparent to those skilled in the art that the same can be applied to a video call or a message transmission.

In the embodiment of FIG. 7, as described above, when the user terminal 100 is located in the free call service area, the user terminal 100 receives a free call service through the indicator 801 as shown in the identifier 510 of FIG. 5. It can indicate that it is located in the area.

In this state, as shown in Fig. 8A, the user can call an application (dialer) having a dial function, input the telephone number of the receiver, and request a call. Then, the controller 150 detects the telephone number input and the call request of the user's receiver through the input unit 130 in step S705. Accordingly, the controller 150 attaches a preset calling code # 803 for the free call service in front of the receiver's phone number in step S710. Thereafter, the controller 150 attempts to connect the call to the telephone number of the receiver to which the calling code # 803 is attached through the communication unit 110 in step S715. An example of such a screen is shown in FIG. As shown, even if the user does not input anything, the call code # 803 is automatically attached when a call is connected in the free call service area, and a call connection is attempted.

On the other hand, after the call connection attempt, the controller 150 records the telephone number of the receiver in the call history, regardless of whether or not the call connection is successful in step S720. At this time, in the present invention, the calling code # 803 attached to the recording of the recipient's phone number in the calling history is removed and stored. An example of such a screen is shown in FIG. As shown, the calling code # which was automatically attached when the call was connected can be recorded as the calling history while being deleted.

As such, according to an embodiment of the present invention, when a call is connected in the free call service area, even if the user does not directly input the call code, the call code can be automatically assigned to connect the call. By omitting and storing as an outgoing call history, convenience can be provided to a user who attempts to recall in a service area other than the free call service area.

9 is a flowchart illustrating a free calling service providing method according to a second embodiment of the present invention, and FIG. 10 is a screen example illustrating a free calling service providing method according to a second embodiment of the present invention.

In the embodiment of FIG. 9, as described above with reference to FIGS. 4 to 6, it is assumed that the user terminal 100 is located in the free call service area.

In this case, as shown in FIG. 10, the indicator 1001 may indicate that the user terminal 100 is currently located in a free call service area.

In the method of providing a free call service according to the second embodiment of the present invention, even if the user is located in the free call service area, the user may select and use a free call or a general call, rather than unconditionally attempting a free call.

That is, the user may call an application (dialer) having a dial function, input a phone number of a receiver, and request a call, as shown in FIG. 10A. Then, the control unit 150 detects the telephone number input and the call request of the user's receiver through the input unit 130 in step S905. Accordingly, the controller 150 may display a screen for selecting whether to perform the call connection in the general call connection or the free call service method in step S910. This selection screen is shown in Fig. 10B.
