As described above, in the embodiments of the present invention, the user provides the network quality information of the access network in response to the provision of the user interface associated with the call, before the free call or video call using the VoIP service, It is possible to improve the satisfaction of the VoIP service while inducing the VoIP service to be selected. For example, when the current quality of the access network provided in advance is high, the user can make a free call or a video call using a VoIP service instead of a general call (for example, a call using a PLMN (Public Land Mobile Network) have. In this case, the user can increase the satisfaction of the VoIP service by receiving the high quality VoIP service, and the provider of the VoIP service obtains the benefit of the more users by the VoIP service. Conversely, if the current quality of the access network provided in advance is low, the user can proceed with a normal call. In this case, it is possible to prevent the user from having a bad prejudice against the VoIP service.

3 to 5 illustrate examples in which a user interface associated with a call is provided, and in response to the provision of such a user interface, a computer device, such as electronic device 1 110 according to the present embodiments, An example of displaying quality information has been described. In the embodiments of FIGS. 3 to 5, the network quality information is expressed by a value within a predetermined range, but it is easily understood by those skilled in the art that a user can express the network quality information by other methods that can be recognized by the user. For example, the network quality information may be displayed in three stages, upper, middle, or lower, or the network quality information may be displayed based on the change in color from red to green. As such, the network quality information can be provided to the user through any one of the ways that the user can recognize the degree of quality of the access network capable of providing the VoIP service. Also, the network quality information is preferably displayed through a location associated with the user interface associated with the call, but is not limited thereto. For example, the network quality information may be displayed on the screen of the electronic device 1 (110) at a position independent of the user interface associated with the call.

A computer device such as electronic device 1 (110) may monitor that a user interface associated with the call is provided to the user. For example, an application installed in the electronic device 1 (110) can confirm that a user interface related to a call has been provided through information on a situation or a key input for providing a user interface related to a call. Information of the network quality information can be displayed on the screen of the computer device such as the electronic device 1 (110) before the start input for the call occurs.

6 is a flowchart illustrating an example of a network quality verification method of an electronic device according to an embodiment of the present invention. The network quality verification method according to embodiments of the present invention can be performed by a computer apparatus such as the electronic apparatus 1 (110) described above. The electronic device 110 may perform the steps 610 to 630 included in the network quality verification method of FIG. For example, the processor 212 of the electronic device 1 (110) may be operable to code the operating system contained in the memory 211, or code of the at least one computer program (e.g., an application provided for the network quality verification method) And may be implemented to execute control instructions. Here, the processor 212 controls the first electronic device 110 so that the first electronic device 110 performs the steps 610 through 630 of FIG. 6 in accordance with the control command provided by the code stored in the first electronic device 110 Can be controlled.

In step 610, the electronic device 1 (110) may recognize the provision of a user interface associated with the call using the electronic device 1 (110). For example, the application installed in the electronic device 1 (110) may include information on a user interface for recognition. For example, information on specific applications providing a call function and information on user interfaces associated with a call in the applications may be stored, and the electronic device 110 (110) And may recognize whether a user interface associated with the call has been provided.

In step 620, in response to the provision of the user interface associated with the call, the first electronic device 110 obtains the network quality information indicating the quality of the access network that is connected to the first electronic device 110 and is capable of providing the VoIP service . For example, provision of a user interface associated with a call may mean that the user intends to make a call or that a path is provided to the user to access the call, wherein the electronic device 1 (110) The network quality information can be obtained in order to provide the network quality information according to the provision of the associated user interface. Techniques for obtaining network quality information will be described in detail later.

In step 630, the first electronic device 110 may display the obtained network quality information on the screen of the electronic device 110 before the start input for the call is generated through the user interface. Accordingly, the first electronic device 110 can prevent the user from entering the VoIP service through the quality of the access network for the VoIP service or from having a bad prejudice against the VoIP service through the low quality access network.

As described above, the user can select either the call using the VoIP service or the call using the VoIP service according to the provided network quality information. On the other hand, according to the network quality information, the call may be automatically performed by selecting either a call using a VoIP service or a general call.

7 is a flowchart illustrating an example of a process of automatically selecting one of a call using a VoIP service and a general call according to the degree of quality set by a user in an embodiment of the present invention. The steps 710 to 750 of FIG. 7 may be performed after step 630 described above with reference to FIG. 6, or may be performed instead of step 630. FIG. 7 shows an example in which steps 710 to 750 are performed after step 630. FIG.

In step 710, the electronic device 1 (110) can provide the user with a function that allows the user to set the degree of quality. For example, if the degree of quality for the access network is in the range of 1 to 10, a function may be provided for the user to select any one of the values from 1 to 10.

In step 720, the first electronic device 110 may store and manage the first degree of quality set through the function of setting the degree of quality. As an example, consider an example in which the user selects 7 out of the 1 to 10 values as the first degree of quality. In this case, the electronic device 1 (110) can store and manage the first degree '7' of the set quality. For example, the first degree '7' of the quality set according to the control of the application installed in the electronic device 1 (110) can be managed.

In step 730, the first electronic device 110 may compare whether the second degree of quality according to the obtained network quality information is equal to or greater than the first degree of the set quality. At this time, the electronic device 110 may perform step 740 if the second degree is greater than or equal to the first degree, and may perform step 750 if the second degree is less than the first degree. As in the above example, if the second degree of quality according to the network quality information is greater than or equal to the first degree " 7 " of the set quality, step 740 may be performed. Conversely, if the second degree is less than the first degree ' 7, then step 750 may be performed.

In step 740, the first electronic device 110 may attempt to connect a call using the VoIP service according to the start input of the user's call. In other words, when the quality of the network quality is high, the electronic device 1 (110) can automatically attempt to connect the call using the VoIP service according to the start input of the user's call. For example, a call using a VoIP service may be attempted even if the user presses a button for a normal call. At this time, the other party of the call can be specified through the account of the selected VoIP service based on the telephone number selected or inputted in association with the ordinary call.

In step 750, the electronic device 1 (110) may try to connect a normal call according to the start input of the user's call. In other words, the electronic device 1 (110) can control the general call to proceed automatically when the network quality is low.

On the other hand, a network verification server can be utilized to acquire network quality information. For example, the network verification server may correspond to the server 150 described with reference to FIG. 1 and FIG. Hereinafter, methods for acquiring network quality information through the network validation server will be described in more detail.

8 is a diagram illustrating a first example of a process of acquiring network quality information in an embodiment of the present invention. 8 shows an electronic device 810 corresponding to the electronic device 1 110 described above and a network verification server 820 corresponding to the server 150 described above.

In step 831, the electronic device 810 that wants to acquire the network quality information can transmit and receive packets with the network verification server 820 for a preset time. For example, the electronic device 810 can exchange RTP (Real-time Transport Protocol) packets with the network validation server 820 for a short time (for example, 500 to 1000 milliseconds).

In step 832, the electronic device 810 may measure at least one of quality information such as latency, loss, and jitter of the transmitted and received packets. Measuring the quality of a network through parameters such as latency, loss, jitter, etc., will be readily apparent to those skilled in the art through well known techniques.

In step 833, the electronic device 810 may calculate, as first network quality information, a VoIP quality index that expresses the quality of the access network at a value within a predetermined range according to the measured at least one quality information.

In other words, in this embodiment, since the packets transmitted and received through the VoIP service can not be used before the VoIP call is started, packets are exchanged between the electronic device 810 and the network verification server 820 for a short time, The first network quality information for the access network can be obtained. Here, the VoIP quality index may be a value within a predetermined range of the quality of the access network as described above.

According to an embodiment, the quality information and the first network quality information may be measured at network verification server 820 and provided to electronic device 810.

The electronic device 810 may use the first network quality information as the network quality information described above, but may further use the second network quality information. The second network quality information may be provided through the network quality information for each access network collected and managed by the network verification server 820.

9 is a diagram illustrating a second example of a process of acquiring network quality information in an embodiment of the present invention. The network validation server 820 according to the present exemplary embodiment collects quality information measured in connection with the access network from a plurality of electronic devices 910, and generates network information for each access network. For example, each of the plurality of electronic devices 910 can measure at least one of quality information of delay time, loss, and jitter of packets transmitted and received in the process of performing a VoIP service, To the verification server 820. The electronic device 810 also measures the quality information of the packets transmitted and received in the process of performing the VoIP service in the case of performing a free call or a video call using the VoIP service and transmits the measured quality information to the network validation server 820 ). In this case, the electronic device 810 may also be one of a plurality of electronic devices 910.

In more detail, when the VoIP service using the access network is selected as the call type through the user interface associated with the call, the electronic device 810 selects at least one of the delay time, loss and jitter for the packets transmitted and received in the course of performing the VoIP service One quality information may be measured, and at least one of the measured quality information and the information about the access network may be linked and transmitted to the network verification server 820.

At this time, each of the plurality of electronic devices 910 may further transmit information on the access network used for performing the VoIP service to the network verification server 820. [ For example, the identifier of the access network may be transmitted to the network verification server 820 with the measured quality information. In this case, the network verification server 820 can generate the network quality information using the quality information, associates the information about the access network with the network quality information generated for the access network, Stored and managed. In other words, the network verification server 820 can obtain the network quality information by the access network. At this time, a plurality of network quality information for the same access network can be obtained. In this case, the network verification server 820 can statistically maintain the network quality information by statistically correlating the network quality information with respect to one access network.

The electronic device 810 may request the network quality information from the network verification server 820 before the start of the call, and the second network 820 may extract the network quality information from the network quality information database 920, Quality information can be received.
