The main functions of the MAC layer include channel management, connection management, service quality management, and power control. and time synchronization, etc., the main functions of the PHY layer are modulation, coding and transmission.

MAC层和PHY层在概念上都包括分别称为MAC层管理单元MLME(MAC sublayermanagement entity)和物理层管理单元PLME(PHY sublayer management entity)的管理单元。这些单元提供了低层管理服务接口，通过这些接口可以调用低层管理功能。Conceptually, both the MAC layer and the PHY layer include management units called MAC layer management unit MLME (MAC sublayer management entity) and physical layer management unit PLME (PHY sublayer management entity). These units provide low-level management service interfaces through which low-level management functions can be invoked.

为了提供正确的MAC操作，每个STA(包括Non-AP STA和AP STA)中都有一个高层管理单元，如SME(station management entity，设备管理单元)，SME表示在MAC层之上的高层管理单元，是一个独立于层的单元，它位于单独的管理平面中。In order to provide correct MAC operation, each STA (including Non-AP STA and AP STA) has a high-level management unit, such as SME (station management entity, equipment management unit), SME means high-level management above the MAC layer A unit, which is a layer-independent unit, resides in a separate management plane.

SME的作用：通常，该单元负责诸如从各种层管理单元(MLME和PLME)收集与层相关的状态之类的功能，类似地，其还会设置特定于层的参数值。SME通常代表一般的系统管理实体执行此类功能。图1描述了管理单元之间的关系。Role of the SME: Typically, this unit is responsible for functions such as collecting layer-related status from the various layer management units (MLME and PLME), and similarly setting layer-specific parameter values. SMEs typically perform such functions on behalf of general system management entities. Figure 1 describes the relationship between management units.

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, enhance functionality through a series of system features and various mechanisms to achieve extremely high throughput. As the use of wireless local area networks (WLANs) continues to grow, it is increasingly important to provide wireless data services in many environments such as homes, businesses and hotspots. In particular, video traffic will continue to be the dominant traffic type in many WLAN deployments. Throughput requirements for these applications are evolving due to the advent of 4k and 8k video (20Gbps uncompressed). New high-throughput, low-latency applications such as virtual or augmented reality, gaming, remote offices, and cloud computing will proliferate (e.g., real-time gaming with sub-5ms latency).

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 WLAN competitiveness by further increasing overall throughput and reducing latency, while ensuring backward compatibility and coexistence with older technology standards. 802.11 compliant devices operating on the 2.4GHz, 5GHz and 6GHz bands.

发明内容Contents of the invention

在传统的无线局域网中，终端可以向接入点请求邻区信息，邻区是指终端当前所连接的接入点相邻的接入点，这样可以帮助终端在发生移动的时候或者当前网络链接丢失的时候，可以更快速的连接到新的接入点，减少网络中断时间。而多链路接入设备可以有多个独立运行的逻辑接入点，使用传统的邻区请求，获得的接入点信息有可能有多个接入点属于同一个多链路接入设备，而当这个接入设备出现故障或设置更改时，其管理的多个逻辑接入点可能都不适合终端接入，而当这个接入设备仅仅是某条链路发生负载过重需要进行负载平衡时，更换到该接入设备的其他逻辑接入点又会让终端获得更短的中断时间。因此，在多链路场景下是比较复杂的。有鉴于此，本申请提供一种获取、发送邻区信息的方法、无线局域网及存储介质。In a traditional WLAN, a terminal can request neighboring cell information from an access point. A neighboring cell refers to an access point adjacent to the access point to which the terminal is currently connected. This can help the terminal move or connect to the current network When lost, you can connect to a new access point more quickly, reducing network interruption time. However, a multi-link access device can have multiple logical access points that operate independently. Using the traditional neighbor cell request, the obtained access point information may have multiple access points belonging to the same multi-link access device. When the access device fails or the settings are changed, the multiple logical access points managed by it may not be suitable for terminal access, and when the access device is only a link that is overloaded, load balancing is required When switching to another logical access point of the access device, the terminal will obtain a shorter interruption time. Therefore, it is more complicated in a multi-link scenario. In view of this, the present application provides a method for acquiring and sending neighboring cell information, a wireless local area network and a storage medium.
