Method for transmitting data and electronic device for doing so

[0001] The present disclosure relates to a method for transmitting data and an electronic device for performing the same. The present disclosure relates to a method for transmitting data using a data transmission method selected based on collected information and an electronic device for performing the same.

[0002] Advances in communication technology have enabled users to access communication services anywhere using Wi-Fi signals. Wi-Fi signals can be transmitted and received from access points (APs) to user devices. The longer the distance between a user device and an AP, the weaker the signal. The closer the AP, the stronger the signal.

[0003] Meanwhile, short-range communication between user terminals is possible, as well as communication between user terminals and AP devices. For example, short-range communication via Bluetooth signals is possible between user terminals. When exchanging data between user terminals, short-range communication via Bluetooth signals has the advantage of fast data transfer speeds, but the disadvantage is that it takes additional time to establish a connection between user terminals.

[0004] Therefore, when transmitting data between user terminals, short-range communication via Bluetooth and communication via Wi-Fi signals are utilized complementarily. For large data transfers, short-range communication via Bluetooth signals allows for faster data transfer, while for smaller data transfers, Wi-Fi signals allow for faster data transfer.

The method may include a step of determining a communication method for transmitting data from the first device to the second device based on whether the size of the data exceeds the threshold.

[0006] An electronic device according to an embodiment of the present disclosure may include a memory and at least one processor. The memory may store one or more instructions. The at least one processor may execute one or more instructions stored in the memory. The at least one processor may obtain first communication information regarding direct communication with an external device by executing the one or more instructions. The at least one processor may obtain second communication information regarding indirect communication with the external device through a medium.

[0026] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0027] FIG. 1 is a conceptual diagram illustrating a method for transmitting data by an electronic device according to an embodiment of the present disclosure.

[0028] Referring to FIG. 1, a first device (10), a second device (20), and a medium (30) are illustrated for convenience of explanation.

[0029] An electronic device according to one embodiment can transmit data to an external device. The electronic device can determine a communication method based on communication information regarding the size of the data and the communication method. The electronic device can transmit data to the external device based on the determined communication method. By determining an efficient communication method according to the situation, the electronic device can improve the data transmission speed.

[0030] For example, in FIG. 1, the electronic device may correspond to the first device (10), and the external device may correspond to the second device (20). Hereinafter, a method of transmitting data based on the first device (10) and the second device (20) will be specifically described.

[0031] In step S10, the first device (10) can transmit data to the second device (20) by directly performing wireless communication with the second device (20). The first device (10) can directly transmit data to the second device (20). The first device (10) can transmit data through a direct communication method such as BLE (Bluetooth Low Energy) or Wi-Fi Direct.

[0032] In step S20, the first device (10) is indirectly connected to the second device (20) through a medium (30), thereby transmitting data to the second device (20). The first device (10) can indirectly transmit data to the second device (20) using the medium (30). The second device (20) can transmit data through an indirect communication method such as a Wi-Fi LAN (Local Area Network).

[0033] For reference, the larger the data to be transmitted, the more advantageous it is to transmit the data using direct communication. The smaller the data to be transmitted, the more advantageous it is to transmit the data using indirect communication. Direct communication, while faster in transmitting data, requires additional time to establish direct communication between the first device (10) and the second device (20).

[0034] In one embodiment, the first device (10) can determine one of the communication method according to step S10 and the communication method according to step S20. The first device (10) can obtain first communication information regarding a direct communication method between the first device (10) and the second device (20). The first device (10) can obtain second communication information regarding an indirect communication method between the first device (10) and the second device (20) through a medium (30). The first device (10) can determine one of the direct communication method and the indirect communication method based on the first communication information and the second communication information.

[0035] In one embodiment, the first device (10) can transmit data to the second device (20) based on the determined communication method. The communication method can be determined based on the size of the data to be transmitted, the signal strength of the communication method, and the network frequency of the communication method.

[0036] For example, depending on the signal strength of the communication method and the network frequency of the communication method, a data size threshold at which the data transmission speeds according to the indirect communication method and the direct communication method are reversed can be determined. For example, the data size threshold can be 50 MB. If the size of the data to be transmitted is less than 50 MB, it is advantageous for the first device (10) to transmit the data through the indirect communication method, and if the size of the data to be transmitted exceeds 50 MB, it is advantageous for the first device (10) to transmit the data through the direct communication method.

[0037] However, if the signal strength of the direct communication method becomes weaker, the data size threshold may increase. In this case, the data size threshold may be determined as 60 MB. If the size of the data to be transmitted is less than 60 MB, the first device (10) transmits the data through the indirect communication method, and if the size of the data to be transmitted exceeds 60 MB, the first device (10) transmits the data through the direct communication method.

[0038] The method for determining the size threshold of data is described in more detail using FIGS. 3 to 9.

The signal strength may be expressed in units of dBm.

[0069] In one embodiment, the signal strength of the first connection and the signal strength of the second connection may be identical.

For example, a multiplying factor of 1 may correspond to a frequency of 2.4 GHz, and a multiplying factor of 5 may correspond to a frequency of 5 GHz. If the network frequency of indirect communication is 2.4 GHz, can be 1, and if the network frequency of indirect communication is 5GHz, can be 5 days.

The threshold value may be proportional to at least one of the network frequency of indirect communication and the signal strength of indirect communication. A method for determining the threshold value using Equation 1 is described below using Equation 1 and Figure 8, which illustrates a detailed example of the situation.

The first device may determine whether the size of the data to be transmitted exceeds a threshold. If the size of the data to be transmitted exceeds the threshold, the first device may determine to transmit the data through direct communication. If the size of the data to be transmitted is less than the threshold, the first device may determine to transmit the data through indirect communication.

[0149] For reference, FIG. 8 is a conceptual diagram specifically explaining the process of determining a threshold value in the method of transmitting data in the situation described in FIGS. 6 and 7.

[0150] Referring to FIG. 8, an electronic device (100) and an external device (200) may establish indirect communication via a medium (300). The indirect communication may be implemented through a first connection between the electronic device (100) and the medium (300) and a second connection between the external device (200) and the medium (300). For example, the indirect communication may be implemented via Wi-Fi, but the method of the indirect communication does not limit the technical idea of ​​the present disclosure.

[0153] For convenience of explanation, the process of deriving a threshold value will be explained using Equation 1 again. Furthermore, Equation 1 is merely an example and does not limit the technical concept of the present disclosure.

[0154] 1. Signal strength of indirect communication

[0155] In one embodiment, the indirect communication may include a first connection between the electronic device (100) and the medium (300) and a second connection between the external device (200) and the medium (300). The signal strength of the indirect communication may be one of the signal strength of the first connection and the signal strength of the second connection. The electronic device may determine one of the signal strength of the first connection and the signal strength of the second connection, and obtain the determined signal strength as the signal strength of the indirect communication.

[0156] In one embodiment, the electronic device (100) may determine a weak signal strength among the signal strengths of the first connection and the second connection as the signal strength of the indirect communication. Since the weak signal strength among the signal strengths of the multiple connections causes a bottleneck in data transmission, it may be determined as the signal strength of the indirect communication. The electronic device (100) may determine a weak signal strength among the signal strengths of the first connection and the second connection as the signal strength of the indirect communication, and may obtain a threshold value based on the determined signal strength of the indirect communication.

[0157] For example, as illustrated in FIG. 8, the signal strength of the first connection may be 87 (dBm). The signal strength of the second connection may be 88 (dBm). Therefore, the signal strength of the first connection may be weaker than the signal strength of the second connection. The electronic device (100) may determine the signal strength of the first connection, 87 (dBm), as the signal strength of the indirect communication. The signal strength of the indirect communication can be 87(dBm).

The electronic device (100) may determine one of the network frequency of the first connection and the network frequency of the second connection, and may acquire the determined network frequency as the network frequency of the indirect communication.

[0161] In one embodiment, the electronic device (100) may determine a weaker network frequency among the network frequencies of the first connection and the second connection as the network frequency of the indirect communication. The weaker network frequency among the network frequencies of the multiple connections may cause a bottleneck in data transmission and thus may be determined as the network frequency of the indirect communication. The electronic device (100) may determine the weaker network frequency among the network frequencies of the first connection and the second connection as the network frequency of the indirect communication and obtain a threshold value based on the determined network frequency of the indirect communication.

[0162] In one embodiment, the network frequency of indirect communication may be a multiplication coefficient corresponding to the frequency of indirect communication. The electronic device (100) may obtain a multiplication coefficient corresponding to the frequency of indirect communication.

The electronic device (100) can obtain a multiplication factor corresponding to the frequency of the second connection. The electronic device (100) can determine a weak frequency among the frequencies of the first connection and the second connection. The electronic device (100) can obtain a multiplication factor corresponding to a connection having a weak frequency, and a network frequency of indirect communication. can be obtained as

[0164] Table 1 below illustrates the correspondence between frequencies and multiplication factors. Using Table 1, we again explain how to determine the network frequency for indirect communication. Of course, the correspondence in the table is merely an example and does not limit the technical concepts of the present disclosure.

[0165] Frequency multiplying factor 2.4GHz15GHz7

[0166] For example, as illustrated in FIG. 8, the frequency of the first connection may be 2.4 GHz. Based on Table 1, the multiplication factor corresponding to the frequency of the first connection is 1. Therefore, the network frequency of the first connection is determined as 1. The frequency of the second connection may be 5 GHz. Based on Table 1, the multiplication factor corresponding to the frequency of the second connection is 7. Therefore, the network frequency of the second connection is determined as 7. The electronic device (100) determines a weak frequency among the frequencies of the first connection and the second connection, and multiplies the network frequency of the indirect communication by the multiplication factor corresponding to the weak network frequency. can be determined. For example, the electronic device (100) can select the frequency of the first connection of 2.4 GHz, which is a weaker frequency among the frequencies of the first connection and the second connection. The multiplication factor corresponding to the frequency of 2.4 GHz is 1, and the electronic device (100) can select the network frequency of the indirect communication. 1 can be obtained as a network frequency of indirect communication. is determined as 1.

[0167] 3. Network frequency for direct communication

[0168] In one embodiment, the signal strength of direct communication can be 74(dBm).

[0169] In one embodiment, the electronic device (100) can determine the network frequency of the direct communication based on the signal strength of the direct communication. The electronic device (100) can indirectly determine the network frequency of the direct communication based on the signal strength of the direct communication.

[0170] In one embodiment, the electronic device (100) may obtain a corresponding multiplication factor when the signal strength of the direct communication exceeds a threshold strength. The electronic device (100) may obtain a corresponding multiplication factor when the signal strength of the direct communication does not exceed the threshold strength.

[0171] For example, the electronic device (100) can obtain the signal strength of direct communication. The electronic device (100) can obtain whether the signal strength of the direct communication exceeds a threshold strength. The electronic device (100) can obtain a corresponding multiplication factor when the signal strength of the direct communication exceeds the threshold strength. Alternatively, the electronic device (100) can obtain a corresponding multiplication factor when the signal strength of the direct communication does not exceed the threshold strength. The numerical value of the threshold strength can be set arbitrarily.

[0172] Table 2 below illustrates the correspondence between signal strength and multiplication factors for direct communication. Using Table 2, we again explain how to determine the network frequency for direct communication. Of course, the correspondences in the table are merely examples and do not limit the technical concepts of the present disclosure.

[0173] Direct communication signal strength multiplying factor >907 901

[0174] For example, as illustrated in FIG. 8, the signal strength of direct communication may be 74 (dBm). Based on Table 2, the multiplication factor corresponding to the signal strength of direct communication of 74 (dBm) is 1. Therefore, the network frequency of direct communication is determined as 1. The electronic device (100) obtains the signal strength of direct communication and multiplies the multiplication factor corresponding to the obtained signal strength of direct communication by the network frequency of direct communication. can be determined by the network frequency of direct communication. is determined as 1.
