Figure 6 is a diagram showing the operation of a user terminal according to an embodiment of the present disclosure. The user terminal can check whether the size of a specific file to be attached to the electronic message exceeds the first size (S601). If the size of a specific file to be attached to an electronic message does not exceed the first size, the user terminal may determine not to transmit the specific file through a file transfer service using an electronic device (S604).

When the size of a specific file to be attached to an electronic message exceeds the first size, the user terminal may check whether the size of the specific file exceeds the second size (S602). Here, the second size may be set larger than the first size. For example, the second size is a value that serves as a standard for the maximum size of a file that can be transmitted at once, and may be preset to a value such as 10GB. If the size of a specific file exceeds the second size, the user terminal may determine not to transmit the specific file through a file transfer service using an electronic device (S604). If the size of the specific file exceeds the second size, the user terminal may not transmit information regarding the transmission of the specific file to the electronic device.

If the size of the specific file does not exceed the second size, the user terminal may decide to transmit the specific file through a file transfer service using an electronic device (S603). The user terminal can transmit information about the transmission of a specific file to the electronic device only when the size of the specific file does not exceed the second size. That is, the electronic device can determine a specific relay server to upload a specific file and perform subsequent operations only when the size of the specific file does not exceed the preset second size. If the size of a specific file exceeds the preset second size, the user terminal may output an error message informing that the specific file cannot be transmitted through the file transfer service.

Operation S601 and operation S602 may be performed simultaneously, or operation S602 may be performed first and then operation S601 may be performed later.

FIG. 7 is a diagram illustrating the operation of an electronic device according to an embodiment of the present disclosure. The electronic device can check whether the remaining storage space of the relay server candidate is greater than or equal to the size of a specific file (S701). If the remaining storage space of the relay server candidate is not larger than the size of the specific file, the electronic device may determine that it is impossible to upload a specific file to the relay server candidate (S704). That is, the electronic device may determine a specific relay server to upload a specific file from among one or more relay server candidates based on the remaining storage space. Specifically, the electronic device may determine a specific relay server to upload a specific file from among relay server candidates whose remaining storage space is equal to or greater than the size of the specific file.

When the remaining storage space of the relay server candidate is greater than or equal to the size of a specific file, the electronic device determines the standard traffic volume corresponding to the relay server candidate by adding the fourth size to the total amount of remaining traffic corresponding to the file stored in the relay server candidate. You can check whether it exceeds (S702). Before explaining operation S702, an embodiment of the remaining traffic amount will be described.

In one embodiment, when a link for downloading a specific file is created, the electronic device may set the remaining traffic volume corresponding to the link for downloading the specific file to a preset fourth size. For example, the fourth size may be preset to a value such as 20GB. This is to prevent one specific file from driving excessive traffic to a specific relay server. When a specific file is downloaded through a link for downloading a specific file, the electronic device deducts the remaining traffic amount by the size of the specific file, and when all remaining traffic amount is deducted, the specific file can be deleted from the specific relay server. Deletion of a specific file according to the deduction of the remaining traffic amount will be explained in detail through operations S805 to S807 of FIG. 8, which will be described later.

In one embodiment relating to operation S702, the electronic device determines a specific relay server to upload a specific file from among one or more relay server candidates, based on the total amount of remaining traffic corresponding to the file uploaded to each relay server candidate. You can. The electronic device is unable to upload a specific file to the relay server candidate when the sum of the remaining traffic volume corresponding to the file stored in the relay server candidate plus the fourth size exceeds the reference traffic volume corresponding to the relay server candidate. It can be judged that it is (S704). The electronic device uploads a specific file to the relay server candidate when the sum of the remaining traffic volume corresponding to the file stored in the relay server candidate plus the fourth size does not exceed the reference traffic volume corresponding to the relay server candidate. It can be determined that it is possible (S703).

Specifically, each relay server candidate may have a corresponding reference traffic amount predetermined. For example, the standard traffic volume corresponding to each relay server candidate may be preset to a value such as 100GB, 200GB, 300GB, etc. For example, the reference traffic volume may be predetermined as an upper limit of the traffic volume that is judged to be able to be appropriately processed by the corresponding relay server candidate. For example, in the worst case, traffic equal to the total amount of traffic corresponding to the files stored in the relay server candidate may be requested to the relay server candidate for a short period of time. Therefore, when a specific file is additionally uploaded to the relay server candidate, the size of the total traffic volume corresponding to the file previously stored in the relay server candidate is added to the fourth size traffic volume corresponding to the newly uploaded specific file. Since it is the total amount of traffic corresponding to the files stored in the server candidate, the electronic device determines the standard traffic amount corresponding to the relay server candidate by adding the fourth size to the total amount of remaining traffic corresponding to the files stored in the relay server candidate. Based on whether or not it exceeds, you can determine a specific relay server to upload a specific file to.

Operation S701 and operation S702 may be performed simultaneously, or operation S702 may be performed first and then operation S701 may be performed later. Additionally, the electronic device may determine a specific relay server to upload a specific file by additionally considering other criteria in addition to the criteria described in operations S701 and S702.

The receiving terminal 8400 may request the download of a specific file from the specific relay server 8300 through a link for downloading the specific file (S802). Specifically, when the receiving terminal 8400 connects through a link for downloading a specific file, a request to download a specific file may be transmitted to the specific relay server 8300.

A specific relay server 8300 may transmit a specific file to the receiving terminal 8400 (S803). When the receiving terminal 8400 downloads a specific file from the specific relay server 8300, the specific file may be transmitted from the user terminal 8100 to the receiving terminal 8400. The specific relay server 8300 may transmit information about the download of a specific file to the electronic device 8200 (S804). For example, when the specific relay server 8300 confirms the completion of transmission of a specific file in operation S803, it may transmit information indicating that the download of the specific file has been completed to the electronic device 8200. Additionally, the specific relay server 8300 may also transmit information about the size of the specific file transmitted in operation S803 to the electronic device 8200.

The electronic device 8200 may deduct the remaining traffic amount for the link for downloading a specific file (S805). For example, the electronic device 8200 determines the size of the specific file transmitted when downloading in operation S803 from the remaining traffic amount corresponding to the link for downloading the existing specific file, that is, the size of the specific file processed by the specific relay server 8300. Traffic volume can be deducted. When all remaining traffic volume is deducted, the electronic device 8200 may transmit a command to delete a specific file to the specific relay server 8300 (S806). That the remaining traffic amount has been completely deducted may mean, for example, that the remaining traffic amount is smaller than the size of the corresponding specific file, so that the specific file can no longer be completely downloaded, or that the remaining traffic amount has become 0. That is, when all remaining traffic volume is deducted according to a preset rule, the electronic device 8200 can delete a specific file from the specific relay server 8300 by transmitting a command to delete the specific file to the specific relay server 8300. there is.

In an embodiment not shown, the electronic device 8200 may delete a specific file from the specific relay server 8300 when a first preset time has elapsed from the time of upload of the specific file. Specifically, the electronic device 8200 may transmit a command to delete a specific file to the specific relay server 8300 when a first period of time has elapsed from the time of upload of the specific file. For example, the first time may be preset to 48 hours, etc. Here, the time point related to the upload of a specific file means, depending on the embodiment, various factors related to the upload of a specific file, such as the time when the upload of the specific file is completed, the time when the upload of the specific file begins, and the time when the upload of the specific file is requested. It can be any one of the viewpoints. The electronic device 8200 may include a timer that counts time from a specific point in time in order to count the time from the point in time regarding the upload of a specific file.

In another embodiment, the time at which a specific file is deleted may be individually input from the user terminal 8100 as a specific time other than the first time from the time of upload of the specific file. In this case, when an input instructing the user terminal 8100 to attach a specific file is received, the user terminal 8100 outputs a GUI for additional input of a specific time, thereby receiving a specific time input from the user. . The electronic device 8200 may transmit a command to delete a specific file to the specific relay server 8300 when the input time has elapsed from the time of uploading the specific file.

In another embodiment, if the user does not transmit an electronic message after a link for downloading a specific file is created, the electronic device 8200 may set a time period shorter than the first time from the time of upload of the specific file. After 2 hours, a specific file can be deleted from a specific relay server (8300). For example, the electronic device 8200 may confirm that an electronic message has not been received through the user terminal 8100. If the electronic message has not been successfully sent, there is a relatively high possibility that the receiving terminal 8400 or another third party will not attempt to download a specific file from the specific relay server 8300, so the specific relay server 8300 In order to quickly secure storage space, a specific file may be deleted from the specific relay server 8300 after a second time period, which is shorter than the first time, has elapsed from the time of upload of the specific file.

When a command to delete a specific file is received from the electronic device 8200, the specific relay server 8300 may delete the specific file (S807). By deleting a specific file from the specific relay server 8300, sufficient storage space of the specific relay server 8300 can be secured.
