背景技术Background Art
802.11be网络，也称为Extremely High Throughput(EHT)网络，通过一系列系统特性和多种机制增强功能以实现极高的吞吐量。随着无线局域网(WLAN)的使用持续增长，对于在许多环境(例如家庭，企业和热点)中提供无线数据服务越来越重要。特别是，视频流量将继续是许多WLAN部署中的主要流量类型。由于出现了4k和8k视频(20Gbps的未压缩速率)，这些应用的吞吐量要求正在不断发展。诸如虚拟现实或增强现实、游戏、远程办公室和云计算之类的新型高吞吐量，低延迟应用程序将会激增(例如，实时游戏的延迟低于5毫秒)。802.11be networks, also known as Extremely High Throughput (EHT) networks, are enhanced through a range of system features and multiple mechanisms to achieve extremely high throughput. As the use of wireless local area networks (WLANs) continues to grow, they are increasingly important for providing wireless data services in many environments, such as homes, enterprises, and hotspots. In particular, video traffic will continue to be the dominant type of traffic in many WLAN deployments. The throughput requirements of these applications are evolving due to the emergence of 4k and 8k video (uncompressed rates of 20Gbps). New high-throughput, low-latency applications such as virtual or augmented reality, gaming, remote offices, and cloud computing will proliferate (e.g., latency below 5ms for real-time gaming).
鉴于这些应用程序的高吞吐量和严格的实时延迟要求，用户期望通过WLAN支持其应用程序时，吞吐量更高，可靠性更高，延迟和抖动更少，电源效率更高。用户期望改进与时敏网络(TSN)的集成，以支持异构以太网和无线LAN上的应用程序。802.11be网络旨在通过进一步提高总吞吐量和降低延迟来确保WLAN的竞争力，同时确保与旧版技术标准向后兼容和共存。在2.4GHz，5GHz和6GHz频段运行的802.11兼容设备。Given the high throughput and stringent real-time latency requirements of these applications, users expect higher throughput, higher reliability, less latency and jitter, and better power efficiency when supporting their applications over WLAN. Users expect improved integration with Time-Sensitive Networking (TSN) to support applications over heterogeneous Ethernet and wireless LANs. 802.11be networks are designed to ensure the competitiveness of WLANs by further increasing aggregate throughput and reducing latency while ensuring backward compatibility and coexistence with older technology standards. 802.11-compatible devices operating in the 2.4GHz, 5GHz, and 6GHz bands.
发明内容Summary of the invention
当终端连接到接入设备时，终端可以通过探测请求消息(如probe request消息)请求接入设备的多条链路信息，现有的解决方案中，在探测请求消息中包含Multi linkelement信息元，其中包含需要获取的链路信息，然而在实际网络部署时，终端使用探测请求消息是当没有读取到接入设备的广播消息(如beacon消息)时，通过探测请求消息来获取接入设备的系统消息，在接收到探测响应消息(如probe response消息)之前，终端无法获知接入设备的系统消息，自然也无法获知当接入设备是多链路设备(即具备可以同时在多条链路上操作的能力的设备)时所配置的链路标识(Link ID)这样的系统消息。所以现有的方案无法在实际网络中实施。有鉴于此，本发明实施例提供一种终端发现和连接到接入设备的方法、装置、系统及介质，使得终端可以通过灵活的请求信息设置，获取需要的链路信息，从而实现多链路连接，最终保障了多链路数据传输。When a terminal is connected to an access device, the terminal can request multiple link information of the access device through a probe request message (such as a probe request message). In the existing solution, the probe request message includes a Multi link element, which includes the link information to be obtained. However, in actual network deployment, the terminal uses the probe request message to obtain the system message of the access device through the probe request message when the broadcast message (such as a beacon message) of the access device is not read. Before receiving the probe response message (such as a probe response message), the terminal cannot obtain the system message of the access device, and naturally cannot obtain the system message such as the link ID configured when the access device is a multi-link device (i.e., a device with the ability to operate on multiple links at the same time). Therefore, the existing solution cannot be implemented in an actual network. In view of this, an embodiment of the present invention provides a method, device, system and medium for a terminal to discover and connect to an access device, so that the terminal can obtain the required link information through flexible request information settings, thereby realizing multi-link connection, and finally ensuring multi-link data transmission.

S1003.STA1接收到probe response消息后，如果消息中包含Multi link element信息元，则将信息元发送给STA1所隶属的终端STA MLD的设备管理单元。STA MLD的设备管理单元根据信息元Link info中的信息和自身业务的需求，决定是否发起多链路连接，例如Link info中提供了另外两条链路的信息，自身需要满足在线游戏或高清视频播放等高速率低延迟的业务，则可以决定需要发起多链路连接，再例如Link info提供了另外两条链路的信息，自身需要满足浏览网页，在线音频播放等低速率的业务，则可以决定不需要发起多链路连接，选择这三条链路中的一条符合业务需求的链路进行连接过程。S1003. After STA1 receives the probe response message, if the message contains the Multi link element information element, it sends the information element to the device management unit of the terminal STA MLD to which STA1 belongs. The device management unit of STA MLD decides whether to initiate a multi-link connection based on the information in the information element Link info and the needs of its own business. For example, if Link info provides information about the other two links and it needs to meet high-speed and low-latency services such as online games or high-definition video playback, it can decide to initiate a multi-link connection. For another example, if Link info provides information about the other two links and it needs to meet low-speed services such as web browsing and online audio playback, it can decide not to initiate a multi-link connection and select one of the three links that meets the business needs to start the connection process.
1)如果需要发起多链路连接，则STA1发送连接请求消息(如association request消息)给AP1，其中包含Multi link element信息元，设置示例如表13。1) If a multi-link connection needs to be initiated, STA1 sends a connection request message (such as an association request message) to AP1, which includes a Multi link element information element.

For example, the determination method may be to select according to the matching of the operating frequency set by the logical terminal with the operating frequency of the link. After the determination, the determined logical terminal sends an association request message to the corresponding AP1, AP2 or AP3. After receiving the association response message from the AP, if the association response message indicates that the request is accepted, the connection is successful, and data is transmitted according to the information in the message; if the association response message indicates that the request is rejected, the connection fails.
