Description

Multi-link equipment connection management method, device, equipment and storage medium

Technical Field

The present application relates to the field of wireless communications, and in particular, to a method, an apparatus, a device, and a storage medium for managing a multi-link device connection.

Background

In the 802.11 system, an access device (AP STA) and a terminal (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 entities referred to as medium access layer management entity mlme (MAC sublayer management entity) and physical layer management entity plme (PHY sublayer management entity), respectively. These entities 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 management entity, such as SME (device management entity), which represents a higher management entity above the MAC layer, is a layer-independent entity, and is located in a separate management plane.

The function of SME: typically, this entity is responsible for functions such as collecting layer-related state from various layer management entities (MLME and PLME), which similarly also sets layer-specific parameter values. SMEs typically perform such functions on behalf of a general system management entity. The layers interact with each other through defined primitives. FIG. 1 depicts the relationships between management entities.

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 is less than 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.

Fig. 2 is a flowchart of a method for managing a multi-link device connection according to an embodiment of the present disclosure. As shown in fig. 2, the multilink device connection management method includes the steps of:

s101, a multilink access device AP MLD sends a connection response message or a disconnection message to a multilink terminal STA MLD, and sets a state parameter value of the STA MLD, wherein the connection response message indicates whether connection establishment is allowed or not.

Specifically, the AP MLD and the STA MLD may each store a STATE parameter of the other party, for example, the AP MLD stores a STATE parameter STA _ STATE of the STA MLD, and the STA MLD stores a STATE parameter AP _ STATE of the AP MLD.

In some embodiments, the AP MLD may indicate the operation range in the connection response message or the disconnection message, if the AP MLD only wants to disconnect on a link on which the STA MLD currently requests to establish a connection or only wants to disconnect on a link on which the disconnection message is currently sent, or if the AP MLD determines that there is a link connection with the STA MLD, the operation range is indicated as a link in the connection response message or the disconnection message, if the AP MLD does not want to connect on all links or wants to disconnect on all links, or if the AP MLD determines that there is no link connection with the STA MLD, the operation range is indicated as a basic service set in the connection response message or the disconnection message. If the connection response message indicates that the connection establishment is not approved and the operation range is the link, or the disconnection response message indicates that the operation range is the link, the AP MLD sets the value of the STA _ STATE to be in a connected STATE; if the connection response message indicates that the connection establishment is not approved and the operating range is the basic service set, or the disconnection response message indicates that the operating range is the basic service set, the AP MLD sets the value of the STA _ STATE to the disconnected STATE. If the connection response message indicates agreement to establish a connection, the AP MLD sets the value of STA _ STATE to a connected STATE.

In some other embodiments, the AP MLD may also set the value of the STA _ STATE according to a connection STATE with the STA MLD, specifically, if the AP MLD and the STA MLD have link connection, the AP MLD sets the value of the STA _ STATE to a connected STATE; if the AP MLD and the STA MLD are not in link connection, the AP MLD sets the value of the STA _ STATE to be in a non-connection STATE.

And S102, after the STA MLD receives the connection response message or the disconnection message sent by the AP MLD, setting the value of the state parameter of the AP MLD.

In some embodiments, the STA MLD may set the value of the AP _ STATE according to information in the connection response message or the disconnection message, specifically, if the connection response message indicates that the connection is not approved and the operating range is the link, or the disconnection message indicates that the operating range is the link, the STA MLD sets the value of the AP _ STATE to the connected STATE; if the connection response message indicates that the connection is not approved and the operation range is the basic service set, or the disconnection response message indicates that the operation range is the basic service set, the STA MLD sets the value of the AP _ STATE to be in a non-connection STATE; if the connection response message indicates agreement to establish a connection, the STA MLD sets the value of AP _ STATE to a connected STATE.

In some other embodiments, the STA MLD may also set the value of the STA _ STATE according to the connection STATE with the AP MLD, specifically, if the STA MLD has a link connection with the AP MLD, the STA MLD sets the value of the AP _ STATE to be in a connected STATE; if the STA MLD and the AP MLD are not in link connection, the STA MLD sets the value of the AP _ STATE to be in a non-connection STATE.

Before the AP MLD sends the connection response message to the STA MLD, the following steps may be further included:

and S1001. the AP MLD sends information of the newly added link to the STA MLD.

The AP MLD may include information of the newly added link in the broadcast message, or may send a dedicated message to the STA MLD, where the dedicated message includes information of the newly added link.

S1002, after receiving information of a new link sent by an AP MLD, if new connection is determined to be established, the STA MLD sends a connection request message to the AP MLD on a first link, wherein the connection request message indicates the STA MLD to request for establishing the connected link, and the first link belongs to the new link.

And S1003. the AP MLD receives the connection request message sent by the STA MLD on the first link.

It should be understood that the connection request message in steps S1002 and S1003 may be an Association request message or a Association request message. Accordingly, the connection response message in steps S101 and S102 may be an Association response message or a re-Association response message.

For a better understanding of the present application, the present application is described below with reference to a specific embodiment. In this embodiment, it is assumed that the STA MLD has three logical terminals STA1, STA2, and STA3, the AP MLD has three logical access points AP1, AP2, and AP3, after the power-on operation, the AP1 is set to operate in the 2.4GHz band, the Link identifier is set to Link 1, the AP2 is set to operate in the 5GHz band, the Link identifier is set to Link 2, and the AP3 does not operate.

Illustratively, the manner of establishing the connection includes the steps of:

s201.STA1 sends a connection request message (such as an Association request message) to the AP1, wherein the message includes a Multi link element information element, and exemplarily, the Multi link element information element includes parameters shown in Table 1. The information contained herein is used to indicate to the AP MLD that multiple link connections are requested to be established.

		Link 1	Capability information and/or operational information of STA1
Link 2	Capability information and/or operational information of STA2

Wherein, Link ID is used for indicating Link identification; the STA info is used to set information of the logical terminal.

At s202, after receiving the connection request message, if the STA1 is granted the connection request, the ap1 sends a connection response message (e.g., Association response message) to the STA1, where the message indicates that the connection establishment is granted, and the connection response message includes a Multi link element information element, which includes, for example, the parameters shown in table 2.

TABLE 2

Link ID	AP info
		Link 1	Capability information and/or operational information of AP1
Link 2	Capability information and/or operational information of the AP2

Wherein, Link ID is used for indicating Link identification; the AP info is used to set information of the logical access point.

If the connection request of STA1 is not approved, a connection response message is sent to STA1 indicating that the connection is not approved. In the embodiment of the present application, it is assumed that the connection response message indicates agreement to establish a connection.

And S203, after the STA1 receives the connection response message, if the connection establishment is agreed by the indication in the message, the connection establishment between the multi-link terminal STA MLD and the multi-link access equipment AP MLD is represented, the STA MLD stores the received link information and the information of the AP, and data transmission is carried out according to the information of the AP.

S204, after the connection is established, the STA MLD sets a parameter AP _ STATE value of the STATE of the locally set AP MLD as STATE _ B; the AP MLD sets a parameter STA _ STATE value of the STATE of the STA MLD which is locally stored as STATE _ B; the value STATE _ B indicates a connected STATE.

After the AP MLD operates for a period of time, when detecting that the number of terminals connected to the device is large or the traffic data volume of the terminal is large, determining to enable the AP3 and operate the AP3 on a 6GHz frequency band, where an operating Link is identified as Link 3, the AP MLD sends information of a newly added Link 3 to the STA MLD, and after the STA MLD receives the information, the STA MLD can reconfigure a Link according to its own requirements, which specifically includes:

and S301, the AP MLD includes the information of the newly added link in a broadcast message (such as beacon message) or a probe response message (probe response message) sent by the AP1 and/or the AP2, as shown in Table 3.

Link ID	AP info
		Link 3	Capability information and/or operational information of the AP3

Alternatively, the first and second electrodes may be,

the AP MLD sends a proprietary message to STA1 via its affiliated AP1 or to STA2 via its affiliated STA2, which contains the same information as above to inform STA MLD that a link is newly added.
