FIG. 2 is a flowchart illustrating an operation in which an electronic device terminates communication between the electronic device and wireless earphones and connects communication between an external device and wireless earphones, according to an embodiment.

In operation 210, the electronic device (e.g., the electronic device 101 of FIG. 1) transmits a first received signal strength power to the electronic device of the wireless earphone and first data retransmission from the electronic device to the wireless earphone. The number of transmissions can be measured periodically. Received signal strength can indicate how much power is received by the receiver. dBm is used as a unit of received signal strength, and the larger the number, the stronger the received signal. The number of data retransmissions may indicate the number of times the transmitter retransmitted data to the receiver. For example, if the receiver fails to accurately decode the data obtained from the transmitter, the receiver transmits information (NACK; Negative Acknowledgment) informing the transmitter of the decoding failure so that the transmitter can retransmit the data in the physical layer. When the receiver accurately decodes the data obtained from the transmitter, it can transmit information (ACK; Acknowledgment) indicating successful decoding to the transmitter, allowing the transmitter to transmit new data. The transmitter can calculate the number of times data is retransmitted before receiving information indicating successful decoding from the receiver.

In operation 220, the electronic device may transmit target data to be transmitted through wireless earphones to an external device. The electronic device can communicate with wireless earphones and external devices. The external device is an electronic device and may be, for example, a smartphone, tablet personal computer, laptop, wearable device, etc., but is not limited thereto. A communication connection can indicate that data can be transmitted and received from each other. The electronic device can transmit the target data to an external device while transmitting the target data to wireless earphones. For example, the target data may be audio data.

In operation 230, the electronic device initiates communication between the electronic device and the wireless earphone when the measured first received signal strength decreases below the first threshold or the measured number of first data retransmissions increases above the first threshold. After finishing, the external device can be controlled to connect communication between the external device and the wireless earphone so that the wireless earphone receives target data from the external device. When communication between the electronic device and the wireless earphone is not smooth, the electronic device may transmit the target data to the wireless earphone via an external device instead of directly transmitting the target data to the wireless earphone. For example, when the second received signal strength for the external device of the wireless earphone is higher than the first received signal strength for the electronic device of the wireless earphone, the electronic device causes the external device to transmit target data to the wireless earphone instead. It can enable wireless earphones to effectively receive target data.

3 and 4 show that the electronic device terminates communication between the electronic device and the wireless earphone, according to an embodiment, and connects communication between the external device and the wireless earphone so that the external device receives target data from the electronic device and transmits it to the wireless earphone. This is a drawing explaining the ordering process.

According to one embodiment, the electronic device 310 (e.g., the electronic device 101 of FIG. 1) may monitor electronic devices capable of communication connection with the electronic device 310. In FIG. 3 , the electronic device 310 can monitor an external device 330 placed around the electronic device 310 and establish communication with the wireless earphone 320 . Here, the electronic device 310 monitoring the external device 330 means that the electronic device 310 determines the location of the external device 330 and transmits information about the external device 330 to the electronic device for communication connection. It may include registration at 310, but data cannot be transmitted or received between the electronic device 310 and the external device 330. The electronic device 310 may establish communication with the wireless earphone 320 and transmit target data to the wireless earphone 320. At this time, the electronic device 310 may connect to the wireless earphone 320 through Bluetooth communication or Wi-Fi communication. The external device 330 can monitor the electronic device 310 capable of communication connection with the external device 330, and the external device 330 and the wireless earphone 320 can monitor each other.

The electronic device 310 may periodically measure the first received signal strength of the wireless earphone 320 to the electronic device 310 and the number of first data retransmissions from the electronic device 310 to the wireless earphone 320. .

In FIG. 4 , the electronic device 310 determines whether the first received signal strength of the wireless earphone 320 for the electronic device 310 decreases below the first threshold or when the strength of the first received signal for the wireless earphone 320 of the electronic device 310 decreases. If the number of first data retransmissions increases beyond the first threshold number, communication between the electronic device 310 and the wireless earphones 320 may be terminated and communication between the external device 330 and the wireless earphones 320 may be connected. . The strength of the received signal to the electronic device of the wireless earphone and the number of data retransmissions from the electronic device to the wireless earphone are determined by the distance between the electronic device and the wireless earphone, obstacles between the electronic device and the wireless earphone, and the number of times the wireless earphone is used. These may be factors that determine the communication status between wireless earphones and the electronic device, reflecting the influence of other electronic devices using a frequency band similar to the frequency band (for example, 2.4 GHz band). In the following specification, the received signal strength and the number of data retransmissions are mainly described as factors used to determine the communication state, but they are not limited thereto, and other factors that can confirm the reception quality may be used to determine the communication state.

According to one embodiment, the electronic device reduces the measured strength of the first received signal to a second threshold value that is greater than the first threshold value or the measured number of first data retransmissions decreases to a second threshold number that is less than the first threshold number. If it increases beyond this, communication with the external device 330 can be established and target data can be transmitted to the external device 330. The electronic device 310 may communicate with the external device 330 through Wi-Fi communication or Bluetooth communication. The difference between the second threshold and the first threshold may be within the range of 2dB to 3dB, but is not necessarily limited thereto. The difference between the second critical number of times and the first critical number of times may be within the range of 2 to 4 times, but is not necessarily limited to this. As communication between the electronic device 310 and the wireless earphone 320 becomes increasingly unstable, the first received signal strength of the wireless earphone 320 to the electronic device 310 gradually decreases to a second threshold. Alternatively, the number of first data retransmissions from the electronic device 310 to the wireless earphone 320 may gradually increase to reach the second threshold number. Reaching the second threshold may include decreasing below the second threshold, and reaching the second threshold number may include increasing above the second threshold number. The electronic device 310 may transmit target data to be transmitted to the wireless earphone 320 to the external device 330 by connecting communication with the external device 330 from a time before ending communication with the wireless earphone 320. In other words, the electronic device 310 can simultaneously transmit target data to the wireless earphones 320 and the external device 330.

Also, after connecting communication with the external device 330, the electronic device 310 terminates communication with the wireless earphone 320, and after terminating communication with the wireless earphone 320, the external device 330 By controlling , communication between the external device 330 and the wireless earphone 320 can be established. The electronic device 310 may transmit a control command to the external device 330 so that the external device 330 can communicate with the wireless earphone 320.

The external device 330 can communicate with the wireless earphone 320 and transmit target data received from the electronic device 310 to the wireless earphone 320. The communication termination time between the electronic device 310 and the wireless earphone 320 and the communication connection time between the external device 330 and the wireless earphone 320 may be different. The wireless earphone 320 cannot receive target data from the time communication with the electronic device 310 ends to the time communication with the external device 330 is connected. However, since the wireless earphone 320 stores some target data received from the electronic device 310 in the buffer memory, communication with the external device 330 is connected from the time communication with the electronic device 310 is terminated. A seamless signal (e.g., an audio signal) can be reproduced by processing some target data stored in the buffer memory up to the point in time. The electronic device 310 can continuously monitor the wireless earphone 320 while terminating communication with the wireless earphone 320, and maintain a communication connection with the external device 330 to transmit target data.

FIG. 5 is a flowchart illustrating a process in which an electronic device connects communication between an external device and wireless earphones and then reconnects communication between the electronic device and wireless earphones, according to an embodiment.

In operation 501, an electronic device (eg, electronic device 101 of FIG. 1) according to an embodiment may establish communication with a wireless earphone. The electronic device can transmit target data to be used for audio playback to wireless earphones.

At operation 502, the electronic device determines whether the first received signal strength of the wireless earphone to the electronic device decreases below a third threshold that is greater than the second threshold or the first number of data retransmissions from the electronic device to the wireless earphone decreases to a second threshold. If the number increases to more than the third threshold number, which is less than the 2 threshold number, the second received signal strength of the wireless earphone to the external device and the third received signal strength to the electronic device of the external device may be periodically requested. For example, the electronic device may request the second received signal strength of the wireless earphone to the external device from the external device or the wireless earphone, and may request the third received signal strength of the external device to the electronic device from the external device.

The difference between the third threshold and the second threshold may be within the range of 2dB to 3dB, but is not necessarily limited thereto. The difference between the second critical number of times and the first critical number of times may be within the range of 2 to 4 times, but is not necessarily limited to this. For example, as the communication between the electronic device and the wireless earphone becomes increasingly unstable, the first received signal strength of the wireless earphone to the electronic device gradually decreases until it reaches a third threshold or from the electronic device to the wireless earphone. The number of first data retransmissions may gradually increase to reach the third threshold number. Reaching the third threshold may include decreasing below the third threshold, and reaching the third threshold number may include increasing above the third threshold number. In other words, the electronic device may periodically check the strength of the second received signal of the wireless earphone to the external device and the strength of the third received signal of the external device to the electronic device from a time before transmitting the target data to the external device.

According to one embodiment, when the first received signal strength changes or the number of first data retransmissions changes, the electronic device may stop requesting the second received signal strength and the third received signal strength. When the first received signal strength increases again beyond the third threshold and the first data retransmission number decreases again below the third threshold number, the electronic device transmits the second received signal strength to the external device of the wireless earphone and the external The request for the third received signal strength to the electronic device of the device may be stopped.

In operation 503, the electronic device determines whether the first received signal strength of the wireless earphone to the electronic device decreases below a second threshold that is greater than the first threshold or the first number of data retransmissions to the wireless earphone of the electronic device decreases to a second threshold. If the second threshold number is smaller than 1, communication with an external device can be established and target data can be transmitted to the external device.

According to one embodiment, the electronic device can connect to an external device through Bluetooth communication or Wi-Fi communication and transmit target data to the external device. In general, because the performance of a Bluetooth antenna placed on an electronic device can be greatly affected by the user's grip on the electronic device (e.g., death grip) and the location where the electronic device is placed, the Wi-Fi antenna placed on the electronic device Using an antenna, you can connect to external devices through Wi-Fi communication. For example, an electronic device can transmit target data to an external device in a short period of time via 2.4GHz Wi-Fi or 5GHz Wi-Fi, which have excellent broadband TCP speeds. For reference, up to three to four Wi-Fi antennas can be placed in an electronic device, so compared to a Bluetooth antenna, it can be relatively less affected by the shape of the user's grip on the electronic device and the location where the electronic device is placed. An external device may store target data received from an electronic device in a buffer memory.

According to one embodiment, while transmitting target data to an external device, if the first received signal strength changes or the number of first data retransmissions changes, the electronic device may stop transmitting the target data to the external device. . For example, when the first received signal strength increases again beyond the second threshold and the first data retransmission number decreases again below the second threshold, the electronic device may terminate communication with the external device; You can stop sending the target data to an external device. Furthermore, when the first received signal strength increases beyond the third threshold and the first data retransmission number decreases below the third threshold, the electronic device transmits a second received signal strength to the external device of the wireless earphone and It is possible to even stop requesting the third received signal strength to the electronic device of the external device.

At operation 504, when the first received signal strength to the electronic device of the wireless earphone decreases below a first threshold or the first number of data retransmissions increases above the first threshold number, the electronic device and the wireless device You can terminate communication between earphones and control the external device to connect communication between the external device and wireless earphones. The electronic device can control the external device to transmit target data to the wireless earphone. Wireless earphones can receive target data from an external device and reproduce signals corresponding to the target data.

According to one embodiment, the electronic device terminates communication between the electronic device and the wireless earphone by additionally considering the second received signal strength of the wireless earphone to the external device and the third received signal strength to the electronic device of the external device, and the external device You can decide whether to connect communication between and wireless earphones. According to one embodiment, the electronic device determines whether to connect communication between an external device and wireless earphones based on a comparison of the first received signal strength and the second received signal strength and a comparison of the third received signal strength and a threshold value. You can decide. For example, when the second received signal strength for the external device of the wireless earphone is greater than the first received signal strength for the electronic device of the wireless earphone and the third received signal strength is greater than the threshold, the electronic device may be connected to the external device. It can be decided to connect communication between wireless earphones. Here, the threshold is the minimum received signal strength required for the electronic device to smoothly transmit data to an external device, and may be a value predetermined by the electronic device. In other words, the electronic device communicates between the external device and the wireless earphones by determining whether the electric field situation between the external device and the wireless earphones is better than that between the electronic device and the wireless earphones and whether the electronic device can smoothly transmit target data to the external device. You can decide whether to connect or not. In other words, even if the first received signal strength decreases below the first threshold or the number of first data retransmissions increases above the first threshold, the electronic device determines that the second received signal strength is greater than the first received signal strength and the third received signal strength is greater than the first received signal strength. If the received signal strength is greater than the threshold, communication between the external device and the wireless earphones can be established.

In operation 505, the electronic device can monitor the wireless earphone even after terminating communication with the wireless earphone, and can check the strength of the first received signal for the electronic device of the wireless earphone by requesting the wireless earphone. Additionally, the electronic device can request and check the strength of the second received signal from the external device of the wireless earphone even after terminating communication with the wireless earphone. In other words, the electronic device can continuously check the first received signal strength and the second received signal strength.

In operation 506, the electronic device may terminate the communication connection between the external device and the wireless earphones and reconnect the communication between the electronic device and the wireless earphones as the communication between the electronic device and the wireless earphones becomes stable again.

According to one embodiment, the electronic device determines whether to reconnect communication between the electronic device and the wireless earphone based on the first received signal strength for the electronic device of the wireless earphone and the second received signal strength for the external device of the wireless earphone. can be decided. According to one embodiment, while communication between an external device and wireless earphones is connected, the electronic device increases the first received signal strength above the second threshold, and the first received signal strength exceeds the second received signal strength. In this case, the external device can be controlled to terminate communication between the external device and the wireless earphones, and communication between the electronic device and the wireless earphones can be reconnected to directly transmit target data to the wireless earphones.

According to one embodiment, the electronic device may determine when to end communication between the external device and the wireless earphone based on data buffered in the wireless earphone. According to one embodiment, when the data size buffered in the wireless earphone of the target data exceeds the threshold data size, the electronic device may control the external device to terminate communication between the external device and the wireless earphone. For example, the time when the communication connection between the wireless earphones and an external device ends and the time when the communication between the wireless earphones and the electronic device is connected are different from each other, so there is a time interval, so even if the device to which the wireless earphones are connected changes, In order to reproduce an uninterrupted signal from wireless earphones, there must be a certain amount of data to be processed by the wireless earphones. Accordingly, the electronic device controls the external device when the data size buffered in the wireless earphone becomes more than the second threshold data size so that the wireless earphone can process the buffered data during the time when communication is switched and play back an uninterrupted signal. Thus, communication between the external device and the wireless earphone can be terminated, and then the electronic device can connect communication with the wireless earphone.

Figure 6 is a diagram explaining the communication connection between an electronic device, an external device, and wireless earphones.

The electronic device 610, wireless earphone 620, and external device 630 can monitor each other. First, the electronic device 610 determines whether the first received signal strength of the wireless earphone 620 to the electronic device 610 decreases below the second threshold or the first received signal strength from the electronic device 610 to the wireless earphone 620 is reduced. When the number of data retransmissions increases beyond the second threshold number, target data can be transmitted to the external device 630 by connecting communication with the external device 630 . In the example of FIG. 6 , the electronic device 610 may connect to the external device 630 through Wi-Fi communication and transmit target data to the external device 630 through Wi-Fi communication. However, it is not limited to this, and the electronic device 610 can be connected to the external device 630 through Bluetooth communication. The external device 630 may store target data received from the electronic device 610 in the memory (eg, buffer memory) 631.

And, when the first received signal strength decreases below the first threshold or the number of first data retransmissions increases above the first threshold, the electronic device 610 and the wireless earphone 620 Communication can be terminated and communication between the external device 630 and the wireless earphone 620 can be connected. As shown in FIG. 6, the external device 630 can communicate with the wireless earphone 620 through Bluetooth communication or Wi-Fi communication. For example, the external device 630 may transmit target data to the wireless earphones 620 through Bluetooth communication, and the external device 630 may transmit target data to the wireless earphones 620 through Wi-Fi communication. . Below, the timing at which the electronic device 610 ends communication with the wireless earphone 620 will be described.

According to one embodiment, the electronic device determines the connection between the electronic device and the wireless earphone after the data size of the data portion other than the data portion processed by the wireless earphone among the data buffered in the external device of the target data becomes larger than the first threshold data size. Communication can be terminated. The external device may transmit the target data by establishing communication with the wireless earphone before receiving all the target data from the electronic device. Therefore, in order to reproduce signals without interruption in wireless earphones, the external device must have sufficient data other than the data processed by the wireless earphones among the target data. Therefore, after the data size of the data portion other than the portion processed by the wireless earphone among the data buffered in the external device becomes larger than the first threshold data, the electronic device is connected to the electronic device to connect communication between the external device and the wireless earphone. Communication between wireless earphones can be terminated.

According to one embodiment, the electronic device may terminate communication between the electronic device and the wireless earphone after the size of the data buffered in the wireless earphone 620 among the target data becomes larger than the second threshold data size. When the wireless earphone switches communication from the electronic device to an external device, the time when the communication connection between the wireless earphone and the electronic device ends and the time when the communication between the wireless earphone and the electronic device are connected may be different. Therefore, in order to reproduce signals without interruption in wireless earphones, there must be a certain amount of data to be processed in wireless earphones in order to reproduce signals without interruption in wireless earphones even when the device through which communication is connected to the wireless earphones is changed. Therefore, the electronic device processes the buffered data during the time when the wireless earphone is switching communication, so that it can reproduce an uninterrupted signal, after the point when the data size buffered in the wireless earphone among the target data becomes larger than the second threshold data size. Communication between the electronic device and the wireless earphones can be terminated, and then the electronic device can control the external device to connect communication between the external device and the wireless earphones.

This is a drawing explaining the process.

According to one embodiment, the electronic device 710 (eg, the electronic device 101 of FIG. 1) may establish communication with the external network 740. The electronic device 710 may connect communication with the external network 740 directly, or may connect communication with the external network 740 through an access point (AP). In other words, connecting the electronic device 710 to communication with the external network 740 may include connecting communication with an access point (AP). As will be described later, terminating communication by the electronic device 710 with the external network 740 may include terminating communication with an access point (AP).

The electronic device 710 may establish communication with the wireless earphone 720. The electronic device 710 may receive real-time data from the external network 740 and transmit the received real-time data to the wireless earphone 720. For example, the electronic device 710 transmits real-time data received from the external network 740 to the wireless earphones 720, allowing the user to use a real-time music streaming service or call function through the wireless earphones 720. You can do it. The external device 730 and the wireless earphone 720 placed around the electronic device 710 can monitor each other, and the external device 730 and the external network 740 can monitor each other. According to one embodiment, the electronic device 710 periodically determines the fourth received signal strength for the external network 740 of the electronic device 710 and the second number of data retransmissions from the external network 740 to the electronic device 710. It can be measured.

In FIG. 8 , the electronic device 710 is configured such that the fourth received signal strength for the external network 740 of the electronic device 710 decreases below the fourth threshold or the fourth received signal strength from the external network 740 to the electronic device 710 is reduced. 2 When the number of data retransmissions increases beyond the fourth threshold number, communication between the electronic device 710 and the wireless earphone 720 is terminated, and the external device 730 is controlled so that the wireless earphone 720 is connected to the external device 730. ), communication between the external device 730 and the external network 740 and communication between the external device 730 and the wireless earphone 720 can be connected to receive real-time data from ). The electronic device 710 may terminate communication with the external network 740 while terminating communication between the electronic device 710 and the wireless earphone 720. In other words, as communication between the electronic device 710 and the external network 740 becomes unstable, the external device 730 instead of the electronic device 710 uses wireless earphones through the external network 740. The external device 730 can be controlled to transmit real-time data to 720. The electronic device 710 can monitor the external network 740 after terminating communication with the external network 740, and can monitor the wireless earphone 720 after terminating communication with the wireless earphone 720. You can.
