Description

Technical Field

[0001] This specification relates to the field of communication technology, and in particular to terminal access methods, devices, electronic equipment and media. Background Technology

[0002] Multi-Link Operation (MLO), a key feature of Wi-Fi 7, significantly improves throughput, reduces latency, and enhances reliability. Many manufacturers keep this feature enabled by default. MLO introduces the concept of a Multi-Link Device (MLD), establishing multiple link associations simultaneously during the association phase. It publishes the frequency band, channel, and rate capabilities of each link through new multi-link information. During data forwarding, the access point (AP) distributes packets to different links for parallel transmission based on link quality and load, achieving bandwidth aggregation and fast link switching, avoiding the interruptions and jitter caused by traditional re-association.

[0003] However, MLO is incompatible with some encryption methods. For example, when configuring MLO, you cannot configure encryption methods such as Open or WPA at the same time. If you do, terminals that support Wi-Fi 7 will not be able to access the AP. Summary of the Invention

[0022] The embodiments described in this specification will now be described in detail.

[0023] The following combination Figure 1 The system architecture of the terminal access methods and devices applicable to the embodiments of this specification will be described. It should be noted that... Figure 1 The examples shown are merely examples of system architectures that can be applied to the embodiments of this specification, in order to help those skilled in the art understand the technical content of this specification, but do not mean that the embodiments of this specification cannot be used in other devices, systems, environments or scenarios.

[0024] Figure 1 This is a schematic diagram of a system architecture illustrated in this specification according to an exemplary embodiment.

[0025] like Figure 1 As shown, this system architecture may include, for example, terminal devices (terminals) and access points (APs). APs can be used to provide wireless signal coverage, allowing terminals to access the network.

[0026] The terminal can be a device with a built-in wireless network card that supports sending and receiving wireless signals, such as mobile phones, laptops, tablets, etc.

[0027] Terminals can connect to an access point to access a wireless local area network (WLAN) and gain internet access.

[0028] According to the embodiments in this specification, the terminal and AP can be located in various IP network environments and multiple network topologies, and can be used in traditional copper cable access and wireless access scenarios as well as fiber optic access scenarios, including FTTR (fiber to the room) all-optical access networks.

[0029] The terminal access method provided in the embodiments of this specification will be described in detail below. For example... Figure 2 As shown, Figure 2 This is a flowchart illustrating a terminal access method according to an exemplary embodiment of this specification. This method can be applied, for example, to an access point (AP). The AP can support multiple frequency bands, such as 5GHz and 6GHz. The AP initially operates in Wi-Fi 7 mode. The terminal access method provided in this embodiment may include the following steps.

[0030] In step 210, when the encryption method is configured as the first preset encryption method, for the target frequency band among multiple frequency bands, the multi-link operation information is deleted from the Wi-Fi 7 management frame corresponding to the target frequency band to obtain the target management frame.

[0031] According to embodiments of this specification, the first preset encryption method can be an encryption method that does not match the MLO (Multi-Link Detection) capability, such as an encryption method with a security level lower than the MLO requirement, like Open and WPA. The default Wi-Fi 7 management frame contains multi-link operation information. This multi-link operation information may include information used to announce MLO capabilities, such as a device identifier representing the MLD (Multi-Link Device), the MLD ID, and link information under the MLD. According to embodiments of this specification, the target frequency band can be configured according to actual needs.

[0032] In step 220, the AP sends a target management frame on the target frequency band.

[0033] According to embodiments of this specification, the AP can, for example, transmit Wi-Fi 7 management frames through a link corresponding to the target frequency band. For example, for 5GHz, the target management frame can be transmitted through 5GHz channel 36.

[0034] In step 230, after the terminal receives the target management frame sent by the AP, it sends a single-link connection request to the AP according to the target management frame.

[0035] According to embodiments of this specification, a single-link connection request can be used to establish a connection with an AP on a target frequency band.

[0036] In step 240, after the AP receives the single-link connection request sent by the terminal, it establishes a single-link connection with the terminal according to the single-link connection request, so that the terminal can access the AP.

[0037] According to embodiments of this specification, the AP may, for example, establish a connection with a terminal on a target frequency band and use this connection to access the terminal.

[0038] According to embodiments of this specification, a Wi-Fi 7 management frame may include a beacon frame or a probe response frame. When the Wi-Fi 7 management frame includes a beacon frame, the AP can remove multi-link operation information from the beacon frame to obtain a target management frame, and then transmit the target management frame on the target frequency band. The terminal can listen for the target management frame on the target frequency band. When the Wi-Fi 7 management frame includes a beacon frame, the terminal can broadcast a probe request frame on the target frequency band. After receiving the probe request frame broadcast by the terminal on the target frequency band, the AP can remove multi-link operation information from the corresponding probe response frame to obtain the target management frame, and then transmit the target management frame to the terminal on the target frequency band.

[0039] If the Access Point (AP) has MLO enabled by default, but the configured encryption method doesn't match MLO (e.g., the encryption method is configured with a low security level like Open or WPA), Wi-Fi 7-enabled devices will experience connection errors when trying to connect to the AP's wireless service, resulting in an inability to access the network. This is because the device recognizes that the AP supports MLO, but the encryption method used has a low security level, causing the AP to refuse connection. This situation can cause inconvenience for users.

[0040] According to the embodiments in this specification, the message format of the Wi-Fi 7 management frames sent by the AP is controlled by encryption. If the current encryption method does not match the MLO (Multi-Link Operation) setting, the multi-link operation information included by default in the Wi-Fi 7 management message is deleted before retransmission. Therefore, the terminal will not initiate a multi-link connection when accessing the AP, thus avoiding connection anomalies.

[0041] The terminal access method is described below with reference to another embodiment. Based on the foregoing embodiments, this embodiment describes a process for a terminal to access an AP when the encryption method is configured as a second preset encryption method, including: In step 250, when the encryption method is configured as the second preset encryption method, the AP sends Wi-Fi 7 management frames on each of the multiple frequency bands. Each Wi-Fi 7 management frame includes a multi-link device identifier and the link information of the corresponding frequency band.

[0042] According to the embodiments of this specification, for each frequency band, the AP can send Wi-Fi 7 management frames through the link corresponding to that frequency band. For example, for 5GHz, the AP can send Wi-Fi 7 management frames through 5GHz channel 36, which include multi-link device identifiers and link information of 5GHz channel 36.

[0043] In step 260, after the terminal receives multiple Wi-Fi 7 management frames sent by the access point AP, the terminal sets the link information corresponding to the same multi-link device identifier as a multi-link AP entity.

[0044] According to the embodiments of this specification, the terminal can aggregate different link information under the same multi-link device identifier and regard them as a single multi-link AP entity.

[0045] In step 270, the terminal sends a multi-link connection request to the AP based on the multi-link AP entity.

[0046] According to embodiments of this specification, a multilink connection request is used to request the establishment of a multilink connection with the AP.

[0047] In step 280, after the AP receives the multi-link connection request sent by the terminal, it establishes a multi-link connection with the terminal according to the multi-link connection request.

[0048] According to the embodiments in this specification, the message format of the Wi-Fi 7 management frames sent by the AP is controlled by the current encryption method. When the current encryption method matches MLO, the AP sends a Wi-Fi 7 management frame to the terminal, carrying a multi-link device identifier and link information for the corresponding frequency band. The terminal can then know that the wireless service it wants to join supports multi-link connections, and accordingly, can choose to establish an MLO multi-link connection during subsequent connection processes. This automatically ensures compatibility with MLO and encryption methods, improving the compatibility of AP terminal access. Furthermore, it shields the upper layers from underlying details, reducing user confusion.

[0049] According to the embodiments of this specification, the terminal can passively scan Wi-Fi 7 management frames or actively scan Wi-Fi 7 management frames.

[0050] For example, Wi-Fi 7 management frames may include beacon frames or probe response frames. When the Wi-Fi 7 management frame includes beacon frames, the access point (AP) can transmit the corresponding beacon frame on each of the multiple frequency bands. The terminal can listen for the corresponding beacon frame on each of the multiple frequency bands. Alternatively, when the Wi-Fi 7 management frame includes beacon frames, the terminal can broadcast probe request frames on each of the multiple frequency bands. The AP receives the probe request frames broadcast by the terminal on the multiple frequency bands and sends the corresponding probe response frame to the terminal on each of the multiple frequency bands.

[0051] The second preset encryption method can include an encryption method that matches MLO, such as WPA3.

[0052] Optionally, when the encryption method is configured as the first preset encryption method, the AP can also enable Wi-Fi 6 working mode (if the AP is currently in Wi-Fi 7 working mode, it will switch from Wi-Fi 7 working mode to Wi-Fi 6 working mode) to connect the terminal to the AP in Wi-Fi 6 working mode. Because MLO is a feature only available in Wi-Fi 7, the AP will not perform multi-link operation in Wi-Fi 6 working mode; the AP will establish a single-link connection with the terminal to connect the terminal.

[0053] Based on the foregoing embodiments, the terminal access method will be described below with reference to another exemplary embodiment: The process of a terminal accessing a wireless service includes stages such as scanning, authentication, and association. For example, the scanning process for a terminal supporting Wi-Fi 7 MLO to access a Wi-Fi 7 AP may include: 1. The terminal starts Wi-Fi and the wireless interface is powered on.

[0054] According to the embodiments in this specification, after the terminal starts Wi-Fi, the terminal's Wi-Fi chip can perform passive scanning (listening for Beacon frames) and / or active scanning (sending Probe Requests) in various frequency bands of 2.4G / 5G / 6G. During the scan, multiple parameters are monitored, such as RSSI, channel, whether it is 6GHz, encryption method, and whether MLO is supported.

[0055] 2. The AP periodically sends Beacon frames.

[0056] According to embodiments of this specification, the AP can, for example, send Beacon frames for each link (e.g., 5GHz channel 36, 6GHz channel 5xx). For APs supporting MLO, each Beacon frame may include an ML Element (Multi-Link Element) in addition to regular information (e.g., SSID, supported rates, security capabilities, etc.). The ML Element may include: MLD is used to identify itself as a Multi-Link Device (MLD). MLD ID, used to provide an identifier for the entire MLD; Information about each link under MLD, such as: link ID, frequency band / channel, bandwidth, MCS / NSS capability, whether MLO is supported, and whether STR (Simultaneous Transmission and Reception) is supported.

[0057] 3. The terminal identifies whether the AP is an MLD.

[0058] According to the embodiments in this specification, when parsing the Beacon / Probe Response, if the terminal finds an ML Element, it confirms that this is an AP (ML-AP) that supports MLO. In this embodiment, the terminal can internally create an "MLD view." Different link information under the same MLD ID is aggregated together and considered as a "multi-link AP entity." After this stage, the terminal can determine whether the wireless service to be joined supports MLO features and whether to establish MLO multi-links during subsequent connection processes.

[0059] According to the embodiments in this specification, when the AP is configured with an encryption method of open or wpa, when the AP sends a Beacon / Probe Response, it can decide not to carry an ML Element in the message based on the current encryption configuration. After the terminal obtains the AP information and parses it, it finds that the AP does not support MLO, so it will not be affected by the encryption method and can complete the normal non-MLO connection process. Disabling MLO has little difference in user experience in general daily use scenarios. When the configured encryption mode is not open or wpa, when the AP sends a Beacon / Probe Response, it can decide to carry an ML Element in the message based on the current encryption configuration, thus announcing MLO capability.

[0060] The terminal access method according to the embodiments of this specification can automatically enable or disable the WI-FI7 MLO feature based on the encryption method currently used by the WLAN, thereby ensuring the compatibility of terminal access and avoiding user inconvenience.

[0061] In a typical implementation, the terminal access method according to the embodiments of this specification can also be applied to an all-optical network environment using an FTTR architecture for access and management of multiple rooms and multiple terminals.

[0070] like Figure 5 As shown, Figure 5 This is a block diagram illustrating another terminal access device according to an exemplary embodiment of this specification, applied to a terminal, the device including: The target management frame receiving module 510 is used to receive the target management frame sent by the access point AP on the target frequency band. The target management frame is obtained by the AP after deleting the multi-link operation information in the Wi-Fi 7 management frame. The single-link connection request sending module 520 is used to send a single-link connection request to the AP according to the target management frame in order to establish a single-link connection with the AP.

[0071] Optionally, the device may further include: The Wi-Fi 7 management frame receiving module is used to receive multiple Wi-Fi 7 management frames sent by the access point (AP). Each Wi-Fi 7 management frame corresponds to a frequency band, and each Wi-Fi 7 management frame includes a multi-link device identifier and the link information of the corresponding frequency band. The configuration module is used to set the link information corresponding to the same multi-link device identifier as a multi-link AP entity; The multi-link connection request sending module is used to send a multi-link connection request to the AP based on the multi-link AP entity in order to establish a multi-link connection with the AP.

[0074] Accordingly, this specification also provides an electronic device including a processor; a memory for storing processor-executable instructions; wherein the processor is configured to: receive a target management frame sent by an access point (AP) on a target frequency band, the target management frame being obtained by the AP after deleting multi-link operation information from a Wi-Fi 7 management frame; send a single-link connection request to the AP based on the target management frame to establish a single-link connection with the AP; and / or receive multiple Wi-Fi 7 management frames sent by the access point AP, the multiple Wi-Fi 7 management frames corresponding one-to-one with multiple frequency bands, each Wi-Fi 7 management frame including a multi-link device identifier and link information of the corresponding frequency band; set the link information corresponding to the same multi-link device identifier as a multi-link AP entity; and send a multi-link connection request to the AP based on the multi-link AP entity to establish a multi-link connection with the AP.

[0075] According to the embodiments in this specification, the message format of the Wi-Fi 7 management frames sent by the AP is controlled by encryption. If the current encryption method does not match MLO (Multi-Link Operation), the multi-link operation information included by default in the Wi-Fi 7 management message is deleted before retransmission. Therefore, the terminal will not initiate a multi-link connection when accessing the AP, thus avoiding connection anomalies. When the current encryption method is compatible with MLO, the AP sends a Wi-Fi 7 management frame to the terminal, carrying the multi-link device identifier and the corresponding frequency band link information. The terminal can then know that the wireless service it wants to join supports multi-link connections and can accordingly choose to establish an MLO multi-link connection during subsequent connection processes.
