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
在引入多链路的技术后，具备可以同时在多条链路上操作的能力的设备称为多链路设备。多链路终端设备可以在业务需要时，将两个逻辑实体设置为逻辑接入点，称为softAP MLD，软接入设备。然而由于多链路终端设备的能力受限，当一条链路在发送数据时，另外的链路可能由于干扰无法接收数据，因此如果像常规的多链路接入设备让两个逻辑接入点独立的让终端设备接入和独立的进行数据会导致数据丢失，数据重传最终使得用户业务延迟较大，实际降低了用户体验。因此在本发明中，软接入设备将两个逻辑接入点的其中一个接入点所在链路设置为主链路，另外一个接入点所在链路设置为非主链路，软接入设备仅在主链路上发送广播消息，而在非主链路上不发送广播消息。有鉴于此，本申请实施例提供一种发现和连接到软接入设备的方法、装置、设备及存储介质。After the introduction of multi-link technology, devices that have the ability to operate on multiple links simultaneously are called multi-link devices. Multi-link terminal devices can set two logical entities as logical access points when business needs, called softAP MLD, soft access devices. However, due to the limited capabilities of multi-link terminal devices, when one link is sending data, the other link may not be able to receive data due to interference. Therefore, if the conventional multi-link access device allows two logical access points to independently allow terminal devices to access and independently perform data, data loss will occur. Data retransmission ultimately causes a large delay in user services, which actually reduces user experience. Therefore, in the present invention, the soft access device sets the link where one of the two logical access points is located as the main link, and the link where the other access point is located as the non-main link. The soft access device only sends broadcast messages on the main link, and does not send broadcast messages on the non-main link. In view of this, the embodiments of the present application provide a method, apparatus, device and storage medium for discovering and connecting to a soft access device.

在本申请所提供的几个实施例中，应该理解到，所揭露的设备、装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述模块的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如一个模块或者组件可以划分为多个模块或组件，或者多个模块或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或模块的间接耦合或通信连接，可以是电性，机械或其它的形式。In the several embodiments provided in the present application, it should be understood that the disclosed devices, apparatuses and methods can be implemented in other ways. For example, the device embodiments described above are merely schematic. For example, the division of the modules is only a logical function division. There may be other division methods in actual implementation. For example, a module or component can be divided into multiple modules or components, or multiple modules or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be through some interfaces, indirect coupling or communication connection of devices or modules, which can be electrical, mechanical or other forms.
