Description

Method, device, equipment and storage medium for establishing soft access point
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method, an apparatus, a device, and a storage medium for establishing a soft access point.
Background
In the 802.11 system, an access device (AP STA) and a terminal device (Non-AP STA) are both internally deployed with a MAC layer and a PHY layer, wherein the main functions of the MAC layer include channel management, connection management, quality of service management, power control, time synchronization, and the like, and the main functions of the PHY layer include modulation, coding, transmission, and the like.
Both the MAC layer and the PHY layer conceptually include management units referred to as a medium access layer management unit MLME (MAC sub management entity) and a physical layer management unit PLME (PHY sub management entity), respectively. These elements provide low-level management service interfaces through which low-level management functions can be invoked.
In order to provide correct MAC operation, each device (including Non-AP STA and AP STA) has a higher layer management unit, such as SME (device management unit), which represents a higher layer management unit above the MAC layer, and is a layer-independent unit, which is located in a separate management plane.
The function of SME: typically, this unit is responsible for functions such as collecting layer-related state from various layer management units (MLME and PLME), which similarly also set layer-specific parameter values. SMEs typically perform such functions on behalf of a general system management unit. The layers interact with each other through defined primitives.
802.11be networks, also known as Extreme High Throughput (EHT) networks, enhance functionality through a range of system features and a variety of mechanisms to achieve very High Throughput. As the use of Wireless Local Area Networks (WLANs) continues to grow, it becomes increasingly important to provide wireless data services in many environments, such as homes, businesses, and hot spots. In particular, video traffic will continue to be the dominant type of traffic in many WLAN deployments. With the advent of 4k and 8k video (uncompressed rate of 20 Gbps), the throughput requirements for these applications are constantly evolving. New high throughput, low latency applications such as virtual reality or augmented reality, gaming, remote offices, and cloud computing will proliferate (e.g., latency for real-time gaming below 5 milliseconds).
In view of the high throughput and stringent real-time latency requirements of these applications, users expect higher throughput, higher reliability, less latency and jitter, and higher power efficiency when supporting their applications over a WLAN. Users desire improved integration with Time Sensitive Networks (TSNs) to support applications on heterogeneous ethernet and wireless LANs. 802.11be networks aim to ensure the competitiveness of WLANs by further increasing overall throughput and reducing latency, while ensuring backward compatibility and coexistence with legacy technology standards. 802.11 compatible devices operating in the 2.4GHz,5GHz and 6GHz bands.
