Abstract
Description
Technical Field
[0001] The present invention relates to communication technologies, and particularly to a wireless transmission method, apparatus, network device, and storage medium. Background Art
[0002] With the development of Wi-Fi6 technology, there are more and more access points AP (Access Point) based on Wi-Fi6. Generally, an AP uses Wi-Fi to connect to another networked AP. A wireless AP usually operates in a traditional mode, that is, the wireless AP includes two modules: a station module bSTA (backhaul STA) for wireless backhaul and a wireless fronthaul module fAP (fronthaul AP) for connecting to another AP or a downlinked wireless station STA.
[0003] However, the inventors of the present application found that in the above-mentioned traditional mode, when the wireless AP communicates with the downlinked STA or another networked AP through DL-OFDMA (Downlink Orthogonal Frequency Division Multiple Access) or UL-OFDMA (Uplink Orthogonal Frequency Division Multiple Access), it cannot communicate with the uplinked networked AP concurrently, which affects the utilization efficiency of the air interface. Summary of the Invention
[0004] An object of an embodiment of the present invention is to provide a network switching method, terminal, and storage medium, so that a network device can communicate with a downlinked device concurrently while communicating with an uplinked device, and improve the utilization efficiency of the air interface.
[0005] To solve the above technical problems, an embodiment of the present invention provides a wireless transmission method, including: broadcasting and sending a beacon frame, and establishing a connection with a first device that scans the beacon frame through a downlink port of the present device; receiving beacon frames broadcast and sent by multiple devices through a channel scanning method, and determining a second device to be connected according to the received multiple beacon frames; information indicating support for a fusion mode is carried in the beacon frame sent by the first device to be connected; the fusion mode includes: when acting as an uplink identity, supporting communication with a device with a downlink identity in a passive trigger manner; establishing a connection with the second device through an uplink port of the present device; starting concurrent communication with the first device and the second device in an active trigger manner.
[0006] An embodiment of the present invention further provides a wireless data transmission device, including: a wireless connection module, configured to broadcast and send beacon frames, and establish a connection with a first device that scans the beacon frames through a lower link port of this device; receive beacon frames broadcast and sent by multiple devices through a channel scanning method, and determine an upper link device according to the received multiple beacon frames; the beacon frame sent by the second device carries target information indicating that the second device supports starting data transmission in a passive trigger manner; establish a connection with the second device through an upper link port of this device; a data transmission module, configured to start data transmission between the first device and the second device in an active trigger manner.
[0007] An embodiment of the present invention further provides a network device, including: at least one processor; and at least one memory; wherein, the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to execute the wireless transmission method as described above.
[0008] An embodiment of the present invention further provides a computer-readable storage medium, storing a computer program, characterized in that when the computer program is executed by a processor, it implements the wireless transmission method as described above.
[0009] Compared with the prior art, the embodiment of the present invention provides a working mode of a network device. When the network device is used as a wireless node for networking, it operates in a fusion mode and connects to lower link devices that also support the fusion mode, that is, the upper link device supports communication with the lower link device in a passive trigger manner; enabling the wireless node to achieve concurrent communication with the upper link device and the lower link device, thereby improving the utilization efficiency of the air interface.
[0010] In addition, the starting of concurrent communication with the first device and the second device in an active trigger manner includes: obtaining channel resources in an air interface competition manner, and performing concurrent communication with the first device and the second device based on the channel resources. That is, a wireless AP operating in a fusion mode competes for the air interface as an upper link device, thereby actively triggering concurrent communication with the upper link device and the lower link device; in this embodiment, the parallel communication between the AP in the fusion mode and the upper link device and the lower link device can be realized based on the existing active trigger communication mechanism, which is not only simple and easy to implement, but also, since the R & D personnel do not need to develop a completely new implementation method, the R & D cost can be reduced as much as possible.
[0011] In addition, before establishing a connection with the second device through the uplink port of the present device, the following steps are also included: sending information indicating support for the fusion mode to the second device, where the fusion mode further includes: when acting as a downlink device, supporting the initiation of communication with an uplink device in an active trigger manner. In this embodiment, on the premise that the network structure remains unchanged, the AP acting as a downlink device supporting the fusion mode can actively trigger communication with the uplink device, and combined with the characteristic of concurrent communication with the uplink and downlink devices, the application scenario of the AP operating in the fusion mode is more flexible.
[0012] In addition, after broadcasting the beacon frame and before establishing a connection with the first device that has scanned the beacon frame through the downlink port of the present device, the following steps are included: receiving information indicating support for the fusion mode sent by the first device. Through the above technical means, the wireless AP in the embodiment of the present invention can simultaneously have the identities of an uplink device and a downlink device, and can be more flexibly applied to different network structures.
[0013] In addition, after broadcasting the beacon frame and before establishing a connection with the first device that has scanned the beacon frame through the downlink port of the present device, the following steps are included: receiving information indicating non - support for the fusion mode sent by the first device. In this embodiment, when the AP operating in the fusion mode communicates with an AP operating in a traditional manner as a downlink device, through the declaration of the supported mode, normal data transmission can still be ensured, and the existing network structure and network devices can be compatible, reducing the development cost.

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and each embodiment. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Those of ordinary skill in the art can understand that in various embodiments of the present invention, many technical details are proposed to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions required to be protected by the present application can still be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation to the specific implementation manners of the present invention. The various embodiments can be combined and cross-referenced with each other on the premise of not being contradictory.
[0027] It should be noted that although functional module division is carried out in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from the module division in the device or the order in the flowchart. Terms such as "first" and "second" in the specification and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to be used to describe a specific order or sequence.
[0028] The first embodiment of the present invention relates to a wireless transmission method, which is applied to a network device, such as a wireless AP. The method includes broadcasting a beacon frame and establishing a connection with a first device that scans the beacon frame through a downstream port of this device; receiving beacon frames broadcast by multiple devices through channel scanning and determining an upstream device to be connected according to the received multiple beacon frames; the beacon frame sent by the upstream device to be connected carries information indicating support for the fusion mode; the fusion mode includes: when acting as the identity of the upstream device, supporting communication with the downstream device in a passive trigger manner; establishing a connection with the upstream device through an upstream port of this device; and initiating concurrent communication with the downstream device and the upstream device in an active trigger manner.
[0029] The following further elaborates on this embodiment in conjunction with the accompanying drawings.
[0030] The wireless transmission method in this embodiment is as Figure 1 shown and includes:
[0031] Step 101, broadcasting a beacon frame and establishing a connection with a first device that scans the beacon frame through a downstream port of this device.
[0032] The wireless networking structure in this embodiment is as Figure 2 shown, where AP0 is the upstream AP, AP1 and AP2 are the downstream APs of AP0, and AP0, AP1, and AP2 all operate in the fusion mode; STA0 is an ordinary terminal connected under AP0, and STA1 and STA2 are ordinary terminals connected under AP1 and AP2 respectively. Among them, AP0, AP1, and AP2 are all wireless APs.
[0033] The following takes AP1 as an example of the execution entity of the wireless transmission method in this embodiment for illustration. During networking, AP1 broadcasts a beacon frame to surrounding devices. In the existing WiFi protocol, the beacon frame, i.e., the Beacon frame, is a wireless signal used to inform other devices that they can access, and the Beacon frame is generally sent periodically. The first device in this embodiment is connected to AP1 through a downstream port, that is, the first device refers to the downstream device of AP1.
[0034] In an example, when a surrounding terminal device or other AP scans the Beacon frame broadcast by the wireless AP, it sends a connection request to AP1 in the identity of the downstream device. After receiving the connection request from the downstream device, AP1 responds to the connection request sent by the downstream device and establishes a connection with the downstream device. For example, when Figure 2 STA1 among them scans the Beacon frame sent by AP1, it will send a connection request to AP1 in the STA role. AP1 responds to the connection request of STA1 and establishes a connection with STA1. Among them, being in the STA role means being in the identity of the downstream device.
[0035] Step 102: receiving Beacon frames broadcasted by multiple devices through channel scanning, and determining a second device to be connected according to the multiple received Beacon frames.
[0036] Step 103: Establish a connection with the second device through the uplink port of the device.
[0037] Specifically, AP1 operating in fusion mode will switch channels for scanning to scan Beacon frames sent by different APs on their corresponding channels, determine the second device to be connected based on the Beacon frames, and then AP1 establishes a connection with the second device to be connected through its uplink port; the second device in this embodiment is connected to AP1 through the uplink port, that is, the second device refers to the uplink device of AP1.
[0038] like Figure 2 In the example, AP1 is connected to AP0 through its uplink port, that is, AP0 is the uplink device of AP1. Among them, AP1 can determine the uplink device to be connected based on the signal strength of each detected Beacon frame, because the greater the signal strength of the Beacon frame, the better the communication quality between the device and the device sending the Beacon frame. For example, the sending device corresponding to the Beacon frame with the strongest signal strength can be determined as the downlink device to be connected.
[0039] The AP running in the converged mode has both the wireless fronthaul fAP function and the wireless backhaul bSTA function. Taking AP1 as an example, when AP1 runs in the converged mode, the uplink device is AP0 and the downlink device is STA1. When AP1 is connected to AP0 and AP1, it can simultaneously receive messages from AP0 and AP1 through the uplink, and can also simultaneously send messages to AP0 and AP1 through the downlink.
[0040] In an example, the process of wireless association between AP1 and the upstream device is as follows: Figure 3 As shown. Among them, AP0 broadcasts Beacon frames in normal working state, indicating that it supports wireless backhaul and communicates with AP nodes running in fusion mode (that is, through the fSTA function in fAP+fSTA). AP1 is in a working state where the uplink port is not connected. When AP1 detects Beacon frames broadcasted by multiple surrounding wireless devices, it determines the uplink device to be connected to each wireless device based on each Beacon frame; among them, the sending device corresponding to the Beacon frame with the strongest signal strength can be selected as the uplink device to be connected. As shown Figure 2Among them, AP0 is the upstream device to be connected. When AP1 receives the Beacon frame broadcast by AP0, AP1 will first send a message carrying the indication that it supports the fusion mode to AP0, that is, inform the upstream device AP0 that AP1, as the downstream device, can initiate communication with the upstream device AP0 in an active trigger manner. Then AP1 associates with AP0 in the STA role in the fusion mode, that is, AP1 establishes a connection with AP0 through the upstream port. Among them, Figure 2 fAP + fSTA in
[0041] Step 104, initiate concurrent communication with the first device and the second device in an active trigger manner.
[0042] Specifically, after AP1 establishes connections with AP0 and the downstream devices, AP1 can actively trigger communication with the upstream device while communicating with the downstream devices. Among them, other APs or attached terminal devices downstream, such as STA1.
[0043] In Figure 2 's example, when AP1 needs to communicate with the upstream device and the downstream devices, it first obtains channel resources through an air interface competition method, and then based on the obtained channel resources, receives packets from the upstream device AP0 and the downstream device STA1 through the uplink, or sends packets to the upstream device AP0 and the downstream device STA1 through the downlink; thus realizing concurrent communication with the downstream device and the upstream device.
[0044] The following describes how AP1 actively triggers communication with AP0 and sends packets to AP0 and STA1. Please refer to Figure 4 .
[0045] When AP1 sends packets to STA1 through DL-OFDMA, the upstream AP0 can participate in receiving packets through DL-OFDMA. Specifically, when AP1 needs to send packets to AP0 and STA1 simultaneously, first AP1 obtains the transmission opportunity through the air interface competition method, and then according to the DL-OFDMA process of Wi-Fi6, broadcasts and sends MU-RTS packets to AP0 and STA1. AP0 and STA1 respectively respond with corresponding CTS packets. Then AP1 sends packets to AP0 and STA1 simultaneously through HE MU PPDU. AP0 and STA1 respectively respond to AP1 through HE TB PPDU with Acknowledgement attached. In this way, AP1 completes sending downstream packets to AP0 and STA1 simultaneously. In this example, both AP1 and AP0 work in the fusion mode.
[0046] The following describes how AP1 actively triggers communication with AP0 and receives packets from AP0 and STA1. Please refer to Figure 5。
[0047] When AP1 receives a message from STA1 through UL-OFDMA, the upstream AP0 can participate in UL-OFDMA to send messages. Specifically, when AP1 wants AP0 and STA1 to send messages simultaneously, first AP1 obtains the transmission opportunity according to the air interface contention method, and then broadcasts the MU-RTS message to AP0 and STA1 according to the UL-OFDMA process of Wi-Fi6. AP0 and STA1 respectively respond with the corresponding CTS messages. Then AP1 broadcasts the Trigger to AP0 and STA1 through the HE MU PPDU. AP0 and STA1 send HE TB PPDU messages to AP1 respectively. AP1 responds to AP0 and STA1 by sending the Multi-STA BlockAck message. In this way, AP1 completes the reception of the uplink messages sent by AP0 and STA1 simultaneously. In this example, both AP1 and AP0 work in the fusion mode.
[0048] It should be noted that the above examples in this embodiment are all illustrative examples for easy understanding and do not limit the technical solutions of the present invention.
[0049] Compared with the prior art, in this embodiment, it is connected to the upstream AP node, the downstream AP node or the attached terminal in the fusion mode. When acting as the downstream AP node in the fusion mode, it can actively trigger the communication with the upstream AP node and the downstream AP node or the attached terminal. At the same time, when acting as the upstream AP node, it can be passively triggered by the downstream AP node or the attached terminal to realize the concurrent communication with the AP node and the downstream AP node or the attached terminal, improving the utilization efficiency of the air interface.
[0050] The second embodiment of the present invention relates to a wireless transmission method. The difference between this embodiment and the first embodiment of the present invention is that the wireless networking structure in this embodiment is as Figure 6 shown. Under AP1 operating in the fusion mode, there is also an AP3 operating in the fusion mode connected. Among them, Figure 6 fAP + fSTA in
[0051] represents the fusion mode.
[0052] As Figure 6As shown in the figure, AP1 is connected to AP0, AP3, and STA1 simultaneously. Among them, AP0 is the upstream device of AP1 and is connected to AP1 through the upstream port of AP1; AP3 is the downstream device of AP1 and is connected to AP1 through the downstream port of AP1. After AP1 broadcasts and sends a Beacon frame carrying a message indicating support for the fusion mode, AP3 learns from the Beacon frame that AP1 supports the fusion mode. Then, after AP1 receives the connection request sent by AP3, it establishes a connection with AP3. Among them, the connection request sent by AP3 carries information indicating its own support for the fusion mode.
[0053] Since AP1 operates in the fusion mode and supports triggering communication with downstream devices in a passive manner, that is, it can communicate with the downstream device AP3 under the trigger of the downstream device AP3.
[0054] The following describes how AP1 is triggered by AP3 to communicate and receive messages from AP3. Please refer to Figure 7 .
[0055] When AP3 wants to send a message to AP1, first, AP3 obtains the transmission opportunity according to the air interface contention method, and then broadcasts and sends a MU-RTS (abbreviation for multi-user request to send, a control message in Wi-Fi6 indicating a request to send, the same below) message to AP1 according to the DL-OFDMA process in the wifi protocol. AP1 responds with a corresponding CTS (Clear To Send, a control message in the Wi-Fi6 protocol indicating permission to send) message. Then, AP3 sends a downstream message to AP1 through a HE MU PPDU (high-efficiency multi-user physical layer protocol data unit, a message in the Wi-Fi6 protocol for an AP to send multiple users' data). AP1 responds to AP3 through a HE TB PPDU (high-efficiency trigger-based physical layer protocol data unit, a message in Wi-Fi6 based on a trigger to carry a single user's data) with an acknowledgement (a confirmation message in Wi-Fi6). In this way, AP1 completes being triggered by AP3 and receiving a message from AP3. In this example, both AP3 and AP1 operate in the fusion mode.
[0056] The following describes how AP1 is triggered by AP3 to communicate and send a message to AP3. Please refer to Figure 7 .
[0057] When AP3 wants to receive a message from AP1, AP3 first obtains the opportunity to send according to the air interface competition method, and then broadcasts the MU-RTS message to AP1 according to the UL-OFDMA process of Wi-Fi6. AP1 responds with the corresponding CTS message. Then AP3 broadcasts the Trigger (a trigger message of Wi-Fi6) message to AP1 and STA4 through HE MU PPDU. AP1 sends the HE TB PPDU message to AP3, and AP3 responds to AP1 by sending the Multi-STABlockAck (a multiple STA block confirmation information in the Wi-Fi6 protocol) message. In this way, AP1 is triggered by AP3 and sends a message to AP3. In this example, AP3 and AP1 both work in converged mode.
[0058] It should be noted that the above examples in this embodiment are all illustrative descriptions for easy understanding and do not constitute a limitation on the technical solutions of the present invention.
[0059] In this embodiment, AP1 as an uplink device in the converged mode can be triggered by AP3 as a downlink device to achieve communication. That is, the AP working in the converged mode not only has the ability to actively trigger the uplink device to communicate, but also has the ability to be triggered to achieve concurrent communication with the AP node and the downlink AP node or the attached terminal, thereby improving the utilization efficiency of the air interface.
[0060] The third embodiment of the present invention relates to a wireless transmission method, which is substantially the same as the first embodiment of the present invention, except that the wireless AP running in the converged mode in the present embodiment is an uplink device, and the downlink device runs in the traditional mode, including a bSTA module with a wireless backhaul function and an fAP module with a wireless fronthaul function. The network structure in the present embodiment is as follows: Figure 9 As shown, AP1 operates in fusion mode; Figure 9 fAP+fSTA in the figure indicates the converged mode. AP4 operates in the traditional mode, STA1 is the terminal device attached to AP1, and STA2 is the terminal device attached to AP2.
[0061] Specifically, in the networking structure of this embodiment, since AP4 as a downlink device operates in a traditional mode, there are two links between AP1 and AP4. If the two networking APs send and receive at the same time, it may cause a message loop, so AP1 and AP2 need to compete for the only message sending and receiving opportunity through the air interface. Before AP1 associates with AP2, after AP1 receives information sent by AP2 that indicates that the fusion mode is not supported, AP2 scans the beacon frame of AP1 through channel scanning, that is, the beacon frame sent by AP1 when it is working as an uplink device in this embodiment.
[0062] The following is attached Figure 9 Taking the networking structure in as an example, the message receiving and sending process between AP1 and AP4 in this embodiment is further described, which specifically includes:
[0063] Step S1, AP1 is ready and broadcasts a Beacon frame to indicate that it supports the fAP+fSTA mode.
[0064] In step S2, the bSTA of AP4 successfully associates with the fAP of AP1 in the role of STA.
[0065] Step S3: AP1 successfully associates with AP4's fAP in the fSTA role.
[0066] Among them, bSTA, STA, fSTA, and fAP can all be understood as a role that the device currently holds.
[0067] That is, the fAP of AP1 to the bSTA of AP4 is the first communication link, and the fAP of AP4 to the fSTA of AP1 is the second communication link. In other words, there are two communication links between AP1 and AP2.
[0068] Step S4: AP1 and AP4 compete for air interface.
[0069] If AP1 obtains the opportunity to send a message, step S5 is executed; if AP2 obtains the opportunity to send a message, step S6 is executed.
[0070] Step S5, AP1 sends a message to the bSTA of AP4 through DL-OFDMA; or receives a message from the bSTA of AP4 through UL-OFDMA.
[0071] Step S6, AP4 sends a message to the fSTA of AP1 through DL-OFDMA; or receives a message from the fSTA of AP1 through UL-OFDMA.
[0072] In this embodiment, since there are two communication links between AP1 and AP4, that is, the fAP of AP1 can send messages to the bSTA of AP4 on the first communication link, and the fAP of AP4 can send messages to the fSTA of AP1 on the second communication link, this may cause the message to loop back between the two communication links, that is, after the message is sent by AP1 to AP4 on the first communication link, it is sent by AP4 to AP1 on the second communication link. Therefore, it is necessary to set an additional mechanism to avoid the message looping back as much as possible.
[0073] In this embodiment, the wireless AP working in the converged mode can also be connected to a traditional AP, that is, an AP working in the traditional mode. The traditional mode means that the wireless AP includes two modules: a station module bSTA for wireless backhaul and a wireless fronthaul module fAP for connecting to another AP or a wireless station STA.
[0074] The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.
