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.

Fig. 1 is a flowchart of a link management method in a multi-link connection scenario according to an embodiment of the present invention. As shown in fig. 1, the link management method in the multi-link connection scenario includes the following steps:
s101, the access device sends a broadcast message (such as beacon message) or a multilink reconfiguration notification message (such as ML reconfiguration NOTIFY message) containing the reconfiguration information element to the terminal.
The reconfiguration information element contains a link identifier and indicates whether a link corresponding to the link identifier is deleted, and when the link corresponding to the link identifier is deleted, the reconfiguration information element also indicates the deletion time of the link corresponding to the link identifier. Optionally, when indicating the link deletion corresponding to the link identifier, a link deletion mode is also indicated in the reconfiguration information element. In the embodiment of the present invention, the reconfiguration information element may include corresponding parameters to indicate whether a link corresponding to the link identifier is deleted, deletion time of the link corresponding to the link identifier, and a link deletion mode, or may use the same parameter to indicate multiple meanings, for example, the reconfiguration information element includes a first parameter for indicating whether the link is deleted and the link deletion mode, and when the first parameter is set to a first value, the first parameter indicates not to be deleted; when the first parameter is set to a second value, indicating that the link stops running; when the first parameter is set to the third value, the terminal is instructed to disconnect the connection on the link, and the specific instruction method is not limited by the present invention.
In some embodiments, the deletion indicates that the terminal is instructed to disconnect from the link or the link stops operating, and the reconfiguration information element includes a second parameter and a third parameter, the second parameter is used for indicating whether the terminal disconnects from the link, and the third parameter is used for indicating whether the link stops operating.
The access device can tell the terminal the specific meaning of deletion indicated in the reconfiguration information element through the parameter setting in the reconfiguration information element, and can also indicate through the sending mode of the reconfiguration information element. Specifically, when the access device determines to stop the operation of the link, the access device sends a broadcast message containing a reconfiguration information element, or sends a first multi-link reconfiguration notification message to the terminal, where the first multi-link reconfiguration notification message contains the reconfiguration information element, and a receiving address in the first multi-link reconfiguration notification message is set as a broadcast address; when the access device needs to execute load balancing and decides to disconnect the link connection of the designated terminal, a second multilink reconfiguration notification message is sent to the designated terminal, wherein the second multilink reconfiguration notification message contains a reconfiguration information element, and a receiving address in the second multilink reconfiguration notification message is set as an address of the designated terminal. Optionally, the reconfiguration information element in the second multi-link reconfiguration notification message further includes a waiting time until a next connection request.
S102, the terminal obtains the reconfiguration information element from the broadcast message or the multilink reconfiguration notification message sent by the access equipment.
And S103, the terminal disconnects the link indicated to be deleted in the acquired reconfiguration information element.
The following exemplary specific manner in which the terminal disconnects the connection on the link indicated as deleted in the obtained reconfiguration information element is given:
1) Stopping transmitting data on the link indicating deletion, disconnecting the link indicating deletion within the deletion time corresponding to the link indicating deletion indicated in the obtained reconfiguration information element, and if there is unsent data, transmitting the data on other links. In the embodiment of the invention, the terminal can disconnect at any time within the deletion time indicated in the reconfiguration information element, including disconnecting when the reconfiguration information element is acquired, or disconnecting until the indicated deletion time.
2) And if the terminal acquires the reconfiguration information element from the broadcast message, if the deletion time corresponding to the link which indicates deletion and is indicated in the acquired reconfiguration information element is not zero, continuing to transmit data on the link which indicates deletion in the deletion time corresponding to the link which indicates deletion and is indicated in the acquired reconfiguration information element, and continuing to read the next broadcast message until the deletion time corresponding to the link which indicates deletion and is indicated in the reconfiguration information element contained in the read broadcast message is zero, stopping transmitting data on the link which indicates deletion and disconnecting the link which indicates deletion.
In some embodiments, before step S103, after the terminal acquires the reconfiguration information element, if there is an indication deletion corresponding to the link identifier in the acquired reconfiguration information element, the terminal checks whether there is a link connected to the access device, except for the link indicated as deletion. If not, the terminal sends a multilink reconfiguration request message to the access equipment, and the multilink reconfiguration request message is used for requesting to establish new connection on the links except the link which is indicated to be deleted, or used for indicating to agree to delete the link which is indicated to be deleted and requesting to establish new connection on the links except the link which is indicated to be deleted; if yes, go to step S103.
Fig. 2 is a flowchart of a link management method in a multi-link connection scenario according to an embodiment of the present invention. Different from the embodiment shown in fig. 1, in the embodiment shown in fig. 2, the terminal, except for disconnecting the link indicated as deleted in the obtained reconfiguration information element, may also request to establish a new connection through a reconnection request manner or a link reconfiguration manner. As shown in fig. 2, the link management method in the multi-link connection scenario includes the following steps:
s201, the access device sends a broadcast message (such as beacon message) or a multilink reconfiguration notification message (such as ML reconfiguration NOTIFY message) containing the reconfiguration information element to the terminal.
S202, the terminal obtains the reconfiguration information element from the broadcast message or the multilink reconfiguration notification message sent by the access equipment.
And S203, the terminal disconnects the link indicated as deleted in the acquired reconfiguration information element, and requests to establish a new connection through a reconnection request mode or a link reconfiguration mode.
Steps S201 and S202 can refer to steps S101 and S102 in the embodiment shown in fig. 1, and are not described herein again. The following only exemplarily introduces several specific methods for a terminal to request to establish a new connection through a reconnection request mode or a link reconfiguration mode:
1) When a terminal needs to add a new link, reading the multilink information in the broadcast message, obtaining currently available link information, if the obtained link information contains links except the links which are indicated to be deleted in the obtained reconfiguration information element, sending a reconnection request message or a multilink reconfiguration request message to the access equipment, requesting to establish connection on the links except the links which are indicated to be deleted in the obtained reconfiguration information element, and if the obtained link information only contains the links which are indicated to be deleted in the obtained reconfiguration information element, not requesting to establish new connection.
2) When the terminal receives a new multilink reconfiguration notification message sent by the access device, wherein the new multilink reconfiguration notification message indicates that the terminal can establish a new connection on a link corresponding to a link identifier contained in the new multilink reconfiguration notification message, the terminal sends a reconnection request message or a multilink reconfiguration request message to the access device to request for establishing a new connection on the link which can establish the new connection.
3) If the terminal acquires the reconfiguration information element from the multilink reconfiguration notification message and the receiving address in the multilink reconfiguration notification message is the address of the terminal, the terminal does not try to request to connect to the link indicated to be deleted in the acquired reconfiguration information element within the predefined time, and after waiting for the predefined time, the terminal sends a reconnection request message or a link reconfiguration request message to the access equipment to request to establish new connection on the link indicated to be deleted in the acquired reconfiguration information element.
If the acquired reconfiguration information element contains the waiting time for requesting connection at the next time, if the terminal acquires the reconfiguration information element from the multilink reconfiguration notification message and the receiving address in the multilink reconfiguration notification message is the address of the terminal, the terminal can also send a reconnection request message or a multilink reconfiguration request message to the access equipment after waiting the waiting time for requesting connection at the next time contained in the acquired reconfiguration information element, and requests to establish new connection on the link which is indicated to be deleted in the acquired reconfiguration information element.
For a better understanding of the present invention, the present invention is further described below in conjunction with a specific application scenario. In the specific application, the access equipment is an access point, the terminal STA MLD is provided with three logical terminals STA1, STA2 and STA3, and the access point AP MLD is provided with three logical access points AP1, AP2 and AP3; STA1 is connected with AP1, the Link identification is Link 1, STA2 is connected with AP2, the Link identification is Link 2, STA3 is connected with AP3, the Link identification is Link 3, and information shown in table 1 is maintained in both STA MLD and AP MLD.
TABLE 1
Link ID AP ID/Address STA ID/Address
Link 1 AP1 STA1
Link 2 AP2 STA2
Link 3 AP3 STA3
The Link ID represents a Link identifier, the AP ID/Address represents an identifier/Address of an access point, and the STA ID/Address represents an identifier/Address of a terminal.
The AP MLD may disconnect from the terminal on one or more links for the following reasons:
1) When the AP MLD finds that the interference on a certain link is too large and the transmission efficiency is too low, the operation on the link is stopped;
2) The AP MLD finds that the use efficiency of a certain link is low, only a few terminals with multi-link capability are connected with the link at present, and the operation of the terminals on the link is stopped for saving energy and wireless resources;
3) The AP MLD finds that the load is too heavy on a certain link, and needs to reduce the load by guiding some conventional single-link terminals to other access links or other access devices, or by disconnecting a multi-link capable terminal on the link.
S1001, when the AP MLD decides to stop running the AP3, namely deleting the Link 3, the STA MLD can be notified in two ways:
1) The AP1, or/and the AP2, or/and the AP3 contain reconfiguration information element reconfiguration IE through beacon messages;
2) Sending an ML reconfiguration NOTIFY message on AP1, or/and AP2, or/and AP3, where the ML reconfiguration NOTIFY message includes a reconfiguration information element reconfiguration IE, and setting a value of a parameter RA (receiving address) as a broadcast address, where the broadcast address is a predefined address, for example, 1.1.1.1; the examples of the reconfiguration IE settings are shown in table 2.
TABLE 2
Figure BDA0003133645430000111
S1002, when an AP MLD needs to perform load balancing and decides to disconnect a part of terminals connected to Link 3 and having multi-Link capability, an ML reconfiguration NOTIFY message is sent on AP1, or/and AP2, or/and AP3, wherein the ML reconfiguration NOTIFY message contains reconfiguration information element Reconfiguration IE, the value of a parameter RA (receiving address) is set as the address of the terminal having multi-Link capability which needs to be disconnected, and when a plurality of terminals having multi-Link capability need to be disconnected on Link 3, an ML reconfiguration NOTIFY message needs to be sent to each terminal independently; the examples of the reconfiguration IE settings are shown in table 3.
TABLE 3
Figure BDA0003133645430000121
S1003. After STA MLD acquires the reconfiguration IE information element from beacon message or ML reconfiguration NOTIFY message through STA1, STA2 or STA3,
3.1 if acquiring a redirection IE information element from the beacon message, checking the value of a Delete Imient parameter corresponding to each Link ID, and if the value is 1, disconnecting the Link corresponding to the Link ID; if the value is 0, it is not disconnected.
