Method, device, system, equipment and storage medium for reducing service delay

Technical Field

The present invention relates to the field of wireless communications, and in particular, to a method, an apparatus, a system, a device, and a storage medium for reducing service latency.

Background

802.11be networks, also known as Extreme High Throughput (EHT) networks, are enhanced by 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 rates 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.

The parameters included in the Multi link element are the same as those in the connection request message, where TID indicates the service class identifier for confirming data that can be transmitted on the link, and PSM parameters indicate the confirmed power saving mode parameters.

And S1003, when downlink data needs to be sent to the STA MLD from the AP MLD, the AP MLD determines a target link for sending the downlink data according to link-specific information of the STA MLD, and sends the downlink data to the terminal through a logical access point operated on the target link.

Specifically, the AP MLD determines the link supporting sending the traffic class according to the comparison between the traffic class identifier TID of the downlink data and the TID mapping table supported by the link, where an example of the TID mapping table supported by the link is shown in table 8. Looking up power saving mode parameters PSM parameters of links supporting sending the service type, calculating the latest awakening time of the links according to First awake time and Interval, comparing the latest awakening time of the logic terminals on the links, and selecting the link with the earliest awakening time as a target link.

And determining a link for sending the downlink data according to the TID mapping table supported by the link and the latest wake-up time, wherein the determination mode can be that firstly, the link supporting the service class of the downlink data to be sent is selected, then, the latest wake-up time of the logic terminals on the links is compared, and the link with the earliest wake-up time is selected as a target link.

Assuming that the target Link is a Link01, the logical access point and the logical terminal connected to each other on the Link are AP1 and STA1, respectively. Sending the downlink data to the STA1 through the AP1 may specifically include:

AP1 sends inquiry information to STA1;

if the STA1 is in the wake-up state, the STA1 can receive the inquiry message of the AP1, and after receiving the inquiry message, sends a response message to the AP1;

after receiving the response message sent by the STA1, the AP1 sends a downlink data packet to the STA1 within the Awake duration, the total time of sending the data packet plus the time of sending the query message plus the time of receiving the response message needs to be less than the value of the parameter Awake duration.

Optionally, the AP1 may include the parameters shown in table 9 in the last data packet sent in the current Awake duration.

After the STA1 receives the parameters shown in table 9, if the value of More data is 0, the STA wakes up at the specified time according to the parameters in the PSM parameters;

if the value of More data is 1, determining a link where the data is received Next time according to a parameter Next awake link, and determining a logic terminal for receiving the data according to a link ID and an STA address/ID in the multi link element; the logic terminal determines the link switching wake-up time and the link switching wake-up duration according to the Next Awake start time and the Awake duration,

When the downlink data required to be sent in step S1003 needs to be sent from AP1 to STA1, if PSM parameters indicate that current STA1 is in the dormant state, it is determined whether there is another link supporting sending the data of the service class according to the service class identifier of the downlink data and the TID mapping table supported by the local link,
