Systems and methods for latency sensitive links
Disclosed herein includes a system, a method, and a device for providing latency sensitive links. A wireless device can receive, from a wireless node, an advertisement message indicating a set of wireless local area network (WLAN) links that support one or more defined latency requirements, a capability of the wireless node to support the set of WLAN links, a plurality of parameters, an operating mode, and a status for the set of WLAN links. The wireless device can send, to the wireless node responsive to the advertisement message, a request to access a first link of the set of WLAN links. The request can indicate a capability of the wireless device to interoperate with the wireless node to use the first link. The wireless device can access the first link of the set of WLAN links if the wireless node accepts the request to access the first link.
1. A method comprising:
receiving, by a wireless device from a wireless node, an advertisement message indicating: a set of wireless local area network (WLAN) links that support one or more defined latency requirements, and capabilities of respective links of the set of WLAN links;
accessing, by the wireless device, a first link of the set of WLAN links according to capabilities of the first link indicated by the advertisement message;
receiving, by the wireless device from the wireless node, an indication of a second link of the set of WLAN links, to which to transfer at least a portion of traffic of the wireless device, from the first link; and
accessing, by the wireless device responsive to the indication, the second link to communicate the at least a portion of the traffic of the wireless device, according to capabilities of the second link indicated by the advertisement message.
2. The method of claim 1 , wherein the capabilities of a respective link include at least one of: latency sensitive capabilities, enhanced distribution channel access (EDCA) parameters, inter-frame spacing parameters, contention window parameters, or a parameter for a timer.
3. The method of claim 1 , wherein the advertisement message includes at least one of: a beacon signal, a probe response or an action frame.
4. The method of claim 1 , wherein the indication is responsive to a condition of network traffic associated with the wireless node.
5. The method of claim 1 , wherein the indication is responsive to a condition that a network load value of the first link is greater than a threshold.
6. The method of claim 5 , wherein the second link is accessed to communicate the at least a portion of the traffic of the wireless device such that the network load value of the first link is less than the threshold and a network load value of the second link is less than the threshold.
7. A wireless device comprising:
one or more processors configured to:
receive, via a receiver from a wireless node, an advertisement message indicating: a set of wireless local area network (WLAN) links that support one or more defined latency requirements, and capabilities of respective links of the set of WLAN links;
access a first link of the set of WLAN links according to capabilities of the first link indicated by the advertisement message;
receive, via the receiver from the wireless node, an indication of a second link of the set of WLAN links, to which to transfer at least a portion of traffic of the wireless device, from the first link; and
access, responsive to the indication, the second link to communicate the at least a portion of the traffic of the wireless device, according to capabilities of the second link indicated by the advertisement message.
8. The wireless device of claim 7 , wherein the capabilities of a respective link include at least one of: latency sensitive capabilities, enhanced distribution channel access (EDCA) parameters, inter-frame spacing parameters, contention window parameters, or a parameter for a timer.
9. The wireless device of claim 7 , wherein the advertisement message includes at least one of: a beacon signal, a probe response or an action frame.
10. The wireless device of claim 7 , wherein the indication is responsive to a condition of network traffic associated with the wireless node.
11. The wireless device of claim 7 , wherein the indication is responsive to a condition that a network load value of the first link is greater than a threshold.
12. The wireless device of claim 11 , wherein the one or more processors are configured to access the second link to communicate the at least a portion of the traffic of the wireless device such that the network load value of the first link is less than the threshold and a network load value of the second link is less than the threshold.
13. A method comprising:
transmitting, by a wireless node to a wireless device, an advertisement message indicating: a set of wireless local area network (WLAN) links that support one or more defined latency requirements, and capabilities of respective links of the set of WLAN links, wherein the wireless device accesses, responsive to the advertisement message, a first link of the set of WLAN links according to capabilities of the first link indicated by the advertisement message; and
responsive to a condition of network traffic associated with the wireless node, transmitting, by the wireless node to the wireless device, an indication of a second link of the set of WLAN links, to which to transfer at least a portion of traffic of the wireless device, from the first link, wherein the wireless device accesses, responsive to the indication, the second link to communicate the at least a portion of the traffic of the wireless device, according to capabilities of the second link indicated by the advertisement message.
14. The method of claim 13 , wherein the capabilities of a respective link include at least one of: latency sensitive capabilities, enhanced distribution channel access (EDCA) parameters, inter-frame spacing parameters, contention window parameters, or a parameter for a timer.
15. The method of claim 13 , wherein the advertisement message includes at least one of: a beacon signal, a probe response or an action frame.
16. The method of claim 13 , further comprising:
determining, by the wireless node, whether a network load value of the first link exceeds a threshold,
wherein responsive to determining that the network load value of the first link exceeds the threshold, the indication of the second link is transmitted to the wireless device.
17. The method of claim 16 , further comprising:
determining, by the wireless node, an amount of the at least a portion of traffic of the wireless device such that the network load value of the first link is less than the threshold and a network load value of the second link is less than the threshold.
18. The method of claim 13 , wherein the condition includes at least one of an amount of traffic on a link, a type of traffic on a link, a network load value for a link, or a network load value for the set of WLAN links.
19. The method of claim 13 , further comprising:
monitoring one or more links of the set of WLAN links to determine the condition of network traffic associated with the wireless node.
20. The method of claim 19 , wherein monitoring the one or more links of the set of WLAN links comprises:
monitoring network load information over the one or more links that are associated with or used by the wireless device; and
determining to maintain a link to the wireless device, disable a link to the wireless device, or transfer traffic associated with the wireless device from one link to another link.
