Description

Technical Field

[0001] This disclosure relates to a method and system, and in particular to a wireless connection method and a multi-device system. Background Technology

[0002] In some Wi-Fi applications, a host device can transmit data with two other devices on the same frequency band via a Wi-Fi access point. However, due to contention-based protocols, the host device cannot transmit data with one of the two devices until it completes data transmission with the other, thus limiting the throughput between the host device and the two devices. Therefore, it is necessary to provide new methods to solve the problems caused by contention-based protocols. Summary of the Invention

[0012] In some embodiments, when the second data transmission amount is greater than the first data transmission amount, the wireless connection method further includes: establishing the first wireless connection with the network access device in the second frequency band via the first electronic device; and establishing the second wireless connection with the network access device in the first frequency band via the second electronic device.

[0013] Another embodiment of this disclosure is a multi-device system. This multi-device system includes a first electronic device and a second electronic device. The first electronic device is used to determine whether a network access device can be used for single-band or multi-band communication, and to establish a first wireless connection with the network access device in a first frequency band. The second electronic device is used to establish a second wireless connection with the network access device in a second frequency band when the network access device can be used for multi-band communication. The transmission bandwidth of the first frequency band is greater than the transmission bandwidth of the second frequency band.

[0014] In some embodiments, the first electronic device is used to perform a network scan to record available network information provided by the network access device, and to determine whether a second network name corresponding to the second frequency band and having the same prefix as the first network name exists in the available network information when the available network information contains a first network name corresponding to the first frequency band. The network access device can be used for multi-band communication when the second network name exists in the available network information, and can be used for single-band communication when the second network name does not exist in the available network information.

[0015] In some embodiments, when the second network name is present in the available network information, the first electronic device is further configured to send the second network name and an access password to the second electronic device via a short-range wireless connection established between the first electronic device and the second electronic device, wherein the first electronic device is configured to use the access password to establish the first wireless connection.

[0016] In some embodiments, the first frequency band corresponds to a first network name, which is indicated by a first beacon signal output by the network access device. The first electronic device is also used to receive a second beacon signal indicating a second network name and to determine whether the second network name has the same prefix as the first network name.

[0048] The following detailed description of embodiments, in conjunction with the accompanying drawings, is provided. However, the specific embodiments described are only for explaining this case and are not intended to limit this case. The description of the structural operations is not intended to limit the order of their execution. Any structure resulting from the recombination of elements and producing an apparatus with equivalent functionality is within the scope of this disclosure.

[0049] The terms "coupled" or "connected" as used in this article can refer to two or more components making direct physical or electrical contact with each other, or making indirect physical or electrical contact with each other, or to two or more components operating or moving together.

[0050] Please see Figure 1 , Figure 1 This is a schematic diagram of a multi-device system 100 according to some embodiments of the present disclosure. In some embodiments, the multi-device system 100 includes a first electronic device 10 and a second electronic device 12. The first electronic device 10, the second electronic device 12, and a computer device 30 can all be moved into a service area of ​​a network access device 20. Therefore, as Figure 1 As shown, the first electronic device 10, the second electronic device 12, and the computer device 30 can all be connected to the network access device 20 to receive network services through the network access device 20. It is worth noting that the first electronic device 10 can communicate with the second electronic device 12 and the computer device 30 on different frequency bands operable by the network access device 20 through the network services provided by the network access device 20. With this configuration, the limitations on transmission throughput between the first electronic device 10, the second electronic device 12, and the computer device 30 caused by contention-based protocols can be mitigated.

[0051] In some embodiments, the network access device 20 can be implemented as a Wi-Fi access point to operate in a Wi-Fi access point mode. In Wi-Fi access point mode, the network access device 20 can broadcast in at least one frequency band. Specifically, the network access device 20 can be used for single-band communication when it can only broadcast in one frequency band (e.g., 2.4 GHz, 5 GHz, or 6 GHz), and can be used for multi-band communication when it can broadcast in more than one frequency band (e.g., 2.4 GHz, 5 GHz, and 6 GHz). The first electronic device 10, the second electronic device 12, and the computer device 30 can all operate in a Wi-Fi station mode to wirelessly connect to the network access device 20 operating in Wi-Fi access point mode.

[0052] In some embodiments, the first electronic device 10 and the second electronic device 12 each include at least one processor, one camera, one storage module, one short-range communication circuit, and one long-range communication circuit. The processor may be coupled to the camera, the storage module, the long-range communication circuit, and the short-range communication circuit. Specifically, the processor may be implemented using a central processing unit (CPU), an application-specific integrated circuit (ASIC), a microprocessor, a system-on-a-chip (SoC), or other suitable processing circuitry. The storage module may be implemented using volatile memory, non-volatile memory, or both. The short-range communication circuit may support Bluetooth Low Energy (BLE), Bluetooth, or other short-range communication protocols. The long-range communication circuit may support Wi-Fi or other long-range communication protocols.

[0053] Following the description of the above embodiments, both the network access device 20 and the computer device 30 also include a communication circuit that supports the Wi-Fi protocol or other long-distance communication protocols. Therefore, as Figure 1 As shown, when the first electronic device 10 is within the service area of ​​the network access device 20, a first wireless connection C1 can be established between the first electronic device 10 and the network access device 20 according to one of the long-range communication protocols (e.g., Wi-Fi protocol). When the second electronic device 12 is within the service area of ​​the network access device 20, a second wireless connection C2 can be established between the second electronic device 12 and the network access device 20 according to one of the long-range communication protocols (e.g., Wi-Fi protocol). Furthermore, when the computer device 30 is within the service area of ​​the network access device 20, another wireless connection can be established between the computer device 30 and the network access device 20 according to one of the long-range communication protocols (e.g., Wi-Fi protocol).

[0054] In some practical applications, the first electronic device 10 and the second electronic device 12 can operate together as a display system. This display system is used to provide users with immersive content (e.g., virtual reality (VR) environments, augmented reality (AR) environments, mixed reality (MR) environments, etc.). Figure 1 As shown, the first electronic device 10 can be a head-mounted device serving as the host of a display system, wherein a user can wear the head-mounted device to perceive immersive content. The second electronic device 12 can be a controller serving as an accessory to the display system, wherein a user can use the controller to control at least one virtual reality object in the immersive content. It should be understood that the second electronic device 12 is not limited to a controller or other accessory. For example, the second electronic device 12 can be an entertainment device (e.g., a game controller, etc.) or a mobile device (e.g., a tablet, smartphone, etc.). Furthermore, the number of second electronic devices 12 is not limited to one (e.g., ...). Figure 1 (as shown) and can be more than 1.

[0055] This section describes the communication between the first electronic device 10 and the computer device 30 via a first wireless connection C1. In one example, the first electronic device 10 can transmit image data associated with immersive content to the computer device 30, thereby sharing the immersive content through the computer device 30. In another example, the first electronic device 10 can receive image data associated with immersive content generated by the computer device 30, thereby providing the immersive content to the user. That is, the computer device 30 can operate as a software server for the display system.

[0056] This section describes the communication between the first electronic device 10 and the second electronic device 12 via a first wireless connection C1 and a second wireless connection C2. In one example, the second electronic device 12 can receive map data associated with a physical environment in which the first electronic device 10 is located from the first electronic device 10. Then, the second electronic device 12 can calculate its attitude data based on the map data using some vision-based positioning technology (e.g., simultaneous localization and mapping technology), and then transmit the attitude data back to the first electronic device 10. In another example, the second electronic device 12 can generate its attitude data using an inertial measurement unit (e.g., an accelerometer, gyroscope, magnetometer, etc.), and then transmit the attitude data to the first electronic device 10. In yet another example, the first electronic device 10 can transmit command data to the second electronic device 12, thereby controlling the second electronic device 12 to operate in an idle mode, a standby mode, or other operating modes.

[0057] In some embodiments, the first electronic device 10 and the second electronic device 12 can communicate with each other without using the first wireless connection C1 and the second wireless connection C2 (i.e., without using the network service provided by the network access device 20). When the first electronic device 10 is close to the second electronic device 12, such as Figure 1 As shown, a short-range wireless connection (CSD) can be established between the first electronic device 10 and the second electronic device 12 according to one of the short-range communication protocols (e.g., Bluetooth Low Energy protocol). The short-range wireless connection (CSD) can be used to transmit data smaller than image data, map data, attitude data, and / or command data.

[0058] The following will further explain a wireless connection method 200 suitable for multi-device system 100. Figure 1 Operation of the multi-device system 100. Please refer to [link / reference]. Figure 2 , Figure 2 This is a flowchart illustrating a wireless connection method 200 according to some embodiments of the present disclosure. In some embodiments, such as Figure 2 As shown, the wireless connection method 200 includes multiple operations S201 to S207.

[0059] In operation S201, the first electronic device 10 determines whether the network access device 20 can be used for single-band communication or multi-band communication, which will be combined with Figure 3 Detailed explanation. Figure 3 This is a flowchart of operation S201 of a wireless connection method 200 according to some embodiments of the present disclosure. In some embodiments, such as Figure 3 As shown, operation S201 includes multiple sub-operations S301 and S302.

[0060] In operation S301, the first electronic device 10 performs a network scan to record available network information (INL) provided by the network access device 20. In some embodiments, when performing a network scan near the network access device 20, the first electronic device 10 receives at least one beacon signal (not shown) periodically output by the network access device 20. Each beacon signal is used to inform a device requiring network service (e.g., the first electronic device 10) of a specific wireless network. For example, each beacon signal may indicate at least the network name and channel information of a specific wireless network. Accordingly, by receiving at least one beacon signal output by the network access device 20, the first electronic device 10 can list at least one wireless network as available network information (INL). It should be understood that the network scan may be a Wi-Fi scan, and the network name is referred to as a Service Set Identifier (SSID).

[0061] Please see Figure 4 and 5 , Figure 4 and 5 These are schematic diagrams illustrating two usage scenarios of the multi-device system 100 according to some embodiments of the present disclosure. In some embodiments, such as Figure 4 and 5 As shown, the available network information INL includes a first network name ID1. Specifically, the first network name ID1 is indicated by a first beacon signal broadcast by the network access device 20.

[0062] Generally, if network access device 20 can be used for multi-band communication, the available network information INL may contain at least two similar network names. Therefore, as... Figure 3 As shown, sub-operation S302 is executed. In sub-operation S302, the first electronic device 10 determines whether a second network name ID2 with the same prefix as the first network name ID1 exists in the available network information INL. It should be understood that the number of characters in the prefix can be preset.

[0063] In some embodiments, such as Figure 4 As shown, the first prefix of the first network name ID1 is "WF". Furthermore, the available network information INL also includes a second network name ID2. It is noteworthy that the second prefix of the second network name ID2 is also "WF", which means that a second beacon signal indicating the second network name ID2 may also be broadcast by the network access device 20. Therefore, in some embodiments of sub-operation S302, the first electronic device 10 determines that the available network information INL contains a second network name ID2 with the same prefix as the first network name ID1. In this case, the network access device 20 can be used for multi-band communication, and as... Figure 2 As shown, multiple operations S202 to S204 are executed.

[0064] In some embodiments, such as Figure 5 As shown, the available network information INL includes the first network name ID1, which begins with "WF", but does not include, for example, Figure 4 The second network name ID2 is shown. Therefore, in some embodiments of sub-operation S302, the first electronic device 10 determines that a second network name ID2 with the same prefix as the first network name ID1 does not exist in the available network information INL. In this case, the network access device 20 can be used for single-band communication, and as shown... Figure 2 As shown, multiple operations S205 to S207 are executed.

[0065] In operation S202, the first electronic device 10 and the network access device 20 establish a first wireless connection C1 in a first frequency band B1. Figure 4In one embodiment, the first beacon signal indicating the first network name ID1 can be broadcast on at least one channel of the first frequency band B1 (e.g., 6 GHz). That is, the first network name ID1 corresponds to the first frequency band B1. The first electronic device 10 can send a first network access request carrying first authentication information (e.g., a first access password) corresponding to the first network name ID1 to the network access device 20. The first authentication information can be pre-stored in the storage module of the first electronic device 10 or can be input to the first electronic device 10 by the user. The network access device 20 can check the first authentication information carried in the first network access request against the first preset information (e.g., a first preset password) corresponding to the first network name ID1 to determine whether the first electronic device 10 can access the first wireless network corresponding to the first network name ID1. Then, when the network access device 20 confirms that the first electronic device 10 can access the first wireless network corresponding to the first network name ID1, as follows: Figure 4 As shown, a first wireless connection C1 is established in the first frequency band B1 corresponding to the first network name ID1.

[0066] In operation S203, the first electronic device 10 sends access information IA corresponding to the second frequency band B2 to the second electronic device 12. Figure 4 In this embodiment, the second beacon signal indicating the second network name ID2 can be broadcast on at least one channel of the second frequency band B2 (e.g., 5 GHz). That is, the second network name ID2 corresponds to the second frequency band B2. The first electronic device 10 uses at least the second network name ID2 and second authentication information (e.g., a second access password) as access information IA, and transmits the access information IA via a short-range wireless connection (CSD). Specifically, the second authentication information may be the same as the first authentication information (i.e., the second access password may be the same as the first access password), but this disclosure is not limited thereto.

[0067] In operation S204, the second electronic device 12 and the network access device 20 establish a second wireless connection C2 in the second frequency band B2. The second electronic device 12 can send a second network access request to the network access device 20 based on access information IA. For example, the second network access request can carry second authentication information corresponding to the second network name ID2. The network access device 20 can check the second authentication information carried in the second network access request against the second preset information corresponding to the second network name ID2 to determine whether the second electronic device 12 can access the second wireless network corresponding to the second network name ID2. Then, when the network access device 20 confirms that the second electronic device 12 can access the second wireless network corresponding to the second network name ID2, as follows... Figure 4 As shown, a second wireless connection C2 is established in the second frequency band B2 corresponding to the second network name ID2.

[0068] As can be seen from the descriptions of operations S202 to S204, the first wireless connection C1 and the second wireless connection C2 are similar in network name. Specifically, the first network name ID1 can be referred to as the network name of the first wireless connection C1, and the second network name ID2, which has the same prefix as the first network name ID1, can be referred to as the network name of the second wireless connection C2.

[0069] In some further embodiments of operations S202-S204, when the available network information INL contains a first network name ID1 and a second network name ID2, the first electronic device 10 searches for which of the first network name ID1 and the second network name ID2 corresponds to the larger transmission bandwidth. Figure 4 In this embodiment, the first electronic device 10 determines that the first frequency band B1 (i.e., 6 GHz) is greater than the second frequency band B2 (i.e., 5 GHz), meaning that the first network name ID1 corresponds to a larger transmission bandwidth. Therefore, the first wireless connection C1 between the first electronic device 10 and the network access device 20 is established in the first frequency band B1, which corresponds to the larger transmission bandwidth. This is because the first electronic device 10, as the host of the display system, typically needs to transmit large amounts of data with multiple devices (e.g., the second electronic device 12 and the computer device 30). Furthermore, since the second electronic device 12, as an accessory to the display system, typically only communicates with the first electronic device 10 and therefore does not need to transmit large amounts of data, the second wireless connection C2 between the second electronic device 12 and the network access device 20 is established in the second frequency band B2, which corresponds to the smaller transmission bandwidth.

[0070] Furthermore, based on the above configuration, a first data transmission between the first electronic device 10 and the second electronic device 12 and a second data transmission between the first electronic device 10 and the computer device 30 can occur simultaneously without competing for the same frequency band.

[0071] Returning to the case where network access device 20 can be used for single-band communication (i.e., Figure 5 In the embodiment described above, during operation S205, the first electronic device 10 and the network access device 20 establish a first wireless connection C1 in the first frequency band B1. The description of operation S205 is similar to that of operation S202, and therefore will not be repeated here.

[0072] In operation S206, the first electronic device 10 sends access information IA corresponding to the first frequency band B1 to the second electronic device 12. Figure 5 In one embodiment, the first electronic device 10 uses at least a first network name ID1 and first authentication information as access information IA.

[0073] In operation S207, the second electronic device 12 and the network access device 20 establish a second wireless connection C2 in the first frequency band B1. The second electronic device 12 can request permission from the network access device 20 to access the first wireless network corresponding to the first network name ID1 based on access information IA. Accordingly, as... Figure 5 As shown, a second wireless connection C2 is established in the first frequency band B1 corresponding to the first network name ID1.

[0074] At Figure 5 In some further embodiments, after listing the first network name ID1 in the available network information INL, the first electronic device 10 may receive a second beacon signal indicating a second network name ID2. In this case, the first electronic device 10 determines whether the second network name ID2 has the same prefix as the first network name ID1. When the second network name ID2 has the same prefix as the first network name ID1, the first electronic device 10 selects the second network name ID2 to generate access information IA to be provided to the second electronic device 12. The description of selecting the second network name ID2 to generate access information IA is similar to the description of operation S203, and is therefore omitted here.

[0075] It should be understood that another network access device may also be configured to broadcast the name of another wireless network having the same prefix as the first network name ID1. Therefore, the first electronic device 10 must further check whether the second beacon signal indicating the second network name ID2 was output by the network access device 20 that output the first beacon signal indicating the first network name ID1. In some further embodiments, when the second network name ID2 has the same prefix as the first network name ID1, the first electronic device 10 calculates a first signal strength value for the first beacon signal and a second signal strength value for the second beacon signal. The first and second signal strength values ​​can be calculated in the same way as the received signal strength indication (RSSI). The first electronic device 10 then determines whether the second signal strength value is closest to the first signal strength value (or determines whether the difference between the second and first signal strength values ​​is less than a preset threshold). Generally, if both the second and first signal strength values ​​are output by the network access device 20, the second signal strength value will be similar to the first signal strength value. Accordingly, when the second signal strength value is closest to the first signal strength value, the first electronic device 10 sends access information IA generated using the second network name ID2 to the second electronic device 12, thereby establishing a second wireless connection C2 between the second electronic device 12 and the network access device 20 in the second frequency band B2 (i.e., operation S204). Furthermore, when the second signal strength value is not closest to the first signal strength value, it means that the second beacon signal is not output by the network access device 20, which leads to the execution of multiple operations S205 to S207.

[0076] To further explain, the signal strength value of the beacon signal may be affected by the transmission distance or obstacles in the transmission path. That is, even if the second signal strength value is closest to the first signal strength value, the second beacon signal may still be output by another network access device. Therefore, the first electronic device 10 must further check whether both the first electronic device 10 and the second electronic device 12 are connected to the same network access device 20. In some further embodiments, the first electronic device 10 determines whether the second electronic device 12 communicates with the first electronic device 10 through the network access device 20. When the second electronic device 12 cannot communicate with the first electronic device 10 through the network access device 20, it means that the second electronic device 12 is connected to a different network access device than the network access device 20, which leads to the execution of multiple operations S205 to S207. When the second electronic device 12 communicates with the first electronic device 10 through the network access device 20, it means that both the first electronic device 10 and the second electronic device 12 are connected to the same network access device 20. In this case, the second wireless connection C2 between the second electronic device 12 and the network access device 20 in the second frequency band B2 is maintained.

[0077] At Figure 4 In some further embodiments, the first electronic device 10 calculates a first data transmission amount for the first wireless connection C1 and receives a second data transmission amount for the second wireless connection C2 calculated by the second electronic device 12. Then, the first electronic device 10 determines that the second data transmission amount is greater than the first data transmission amount. In this case, the first wireless connection C1 switches from the first frequency band B1 to the second frequency band B2, and the second wireless connection C2 switches from the second frequency band B2 back to the first frequency band B1.

[0078] Please see Figure 6 , Figure 6 This is a schematic diagram illustrating a usage scenario of a multi-device system 100 according to some embodiments of the present disclosure. In some embodiments, the first electronic device 10 can use the second network name ID2 and the second authentication information described at least in operation S203 to re-establish a first wireless connection C1 with the network access device 20 in the second frequency band B2. Furthermore, the first electronic device 10 can transmit the first network name ID1 and the first authentication information described at least in operation S202 as access information IA to the second electronic device 12 via a short-range wireless connection CSD. Accordingly, the second electronic device 12 can re-establish a second wireless connection C2 with the network access device 20 in the first frequency band B1.

[0079] As can be seen from the above embodiments of this disclosure, by monitoring the data transmission volumes of multiple wireless connections between multiple electronic devices and network access device 20 in the multi-device system 100, the multi-device system 100 can arrange the multiple wireless connections in appropriate frequency bands when the data transmission volumes of the multiple wireless connections change. In summary, the multi-device system 100 and wireless connection method 200 of this disclosure have advantages such as optimizing system transmission throughput.

[0080] The methods of this disclosure can exist in the form of program code. The program code can be contained in a physical medium, such as a floppy disk, optical disk, hard disk, or any other transient or non-transitory computer-readable storage medium, wherein when the program code is loaded and executed by a computer, the computer becomes an apparatus for implementing the methods. The program code can also be transmitted via some transmission medium, such as wires or cables, via optical fibers, or via any other transmission mode, wherein when the program code is received, loaded, and executed by a computer, the computer becomes an apparatus for implementing the methods. When implemented on a general-purpose processor, the program code, in conjunction with the processor, provides a unique apparatus that operates similarly to an application-specific integrated circuit (ASIC).

[0081] Although the present disclosure has been described above with reference to embodiments, it is not intended to limit the present disclosure. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the appended claims.
