Abstract

The exemplary embodiments provide at least a method of receiving, by a node of a wireless communication network, more than one indication of data required to be sent from devices in the network, determining that provisioning resources to send the data in response to each of the more than one indication exceeds at least one threshold, and based on the determining, sending a probe message including a priority constraint to the devices. Further, receiving, at a device of a wireless communication network, a probe message from a network node of the network, the probe message identifying a priority constraint, sending, by the device, an acknowledgement to the probe message, the acknowledgment indicating that the device has data to send which meets or exceeds the priority constraint identified in the probe message, and in response to the acknowledgment, receiving from the network node a resource allocation to send the data.

First claim

What is claimed is:

1. A method comprising:
receiving, by an access point of a wireless local area network, more than one indications of data required to be sent from devices in the wireless local area network;
determining by the access point that the more than one received indications exceed a number of resource allocations which can be performed during a period of time; and
based on the determining, sending, by the access point, a probe message comprising a priority constraint to the devices, wherein the priority constraint is for determining by the devices whether the devices may request a resource allocation.

2. The method according to claim 1 , further comprising:
receiving an acknowledgement to the probe message from one or more of the devices with data to send, the data to send having a priority which at least one of meets or exceeds the priority constraint identified in the probe message; and
allocating a resource to the one or more of the devices in order to send the data.

3. The method according to claim 1 , wherein the priority constraint identified in the probe message is associated with a classification comprising at least one of regular reporting, low activity, medium activity, strong activity and malfunction detected.

4. The method according to claim 1 , wherein the more than one indications are received in response to a probe message previously sent to devices in the wireless local area network.

5. The method according to claim 1 , wherein the priority constraint identified in the probe message comprises at least one of significance level, priority of traffic, and delay tolerance.

6. The method according to claim 1 , wherein the priority constraint identified in the probe message is application specific, and wherein the application comprises at least one of infrastructure monitoring, traffic monitoring, environmental monitoring, and hospital/health care equipment/environment monitoring.

7. A non-transitory computer readable memory embodying at least one computer program code, the at least one computer program code executable by at least one processor to perform the method according to claim 1 .

8. An apparatus comprising: at least one processor; and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least perform or control the following:
receiving, with an access point of a wireless local area network, more than one indications of data required to be sent from devices in the wireless local area network;
determining by the access point that the more than one received indications exceed a number of resource allocations which can be performed during a period of time; and
sending, by the access point, based on the determining, a probe message comprising a priority constraint to the devices, wherein the priority constraint is for determining by the devices whether the devices may request a resource allocation.

9. The apparatus according to claim 8 , wherein the at least one memory including the computer program code is configured, with the at least one processor, to cause the apparatus to at least further perform or control the following:
receiving an acknowledgement to the probe message from one or more of the devices with data to send, the data to send having a priority which at least one of meets or exceeds the priority constraint identified in the probe message; and
allocating a resource to the one or more of the devices in order to send the data.

10. The apparatus according to claim 8 , wherein the priority constraint identified in the probe message is associated with a classification comprising at least one of regular reporting, low activity, medium activity, strong activity and malfunction detected.

11. The apparatus according to claim 8 , wherein the more than one indications are received in response to a probe message previously sent to devices in the wireless local area network.

12. The apparatus according to claim 8 , wherein the priority constraint identified in the probe message comprises at least one of significance level, priority of traffic, and delay tolerance.

13. The apparatus according to claim 8 , wherein the priority constraint identified in the probe message is application specific, and wherein the application comprises at least one of infrastructure monitoring, traffic monitoring, environmental monitoring, and hospital/health care equipment/environment monitoring.

14. A method comprising:
sending, by a device of a wireless local area network, an indication of data required to be sent, to an access point of the wireless local area network;
receiving, by the device, a probe message from the access point, the probe message identifying a priority constraint, wherein the priority constraint is for determining by the device whether the device may request a resource allocation;
sending, by the device, an acknowledgement to the probe message, the acknowledgment indicating that the device has data to send which meets or exceeds the priority constraint identified in the probe message; and
in response to the acknowledgment, receiving, by the device from the access point, a resource allocation to send the data.

15. The method according to claim 14 , wherein the priority constraint identified in the probe message is associated with a classification comprising at least one of regular reporting, low activity, medium activity, strong activity and malfunction detected.

16. The method according to claim 14 , wherein the priority constraint identified in the probe message comprises at least one of significance level, priority of traffic, and delay tolerance.

17. The method according to claim 14 , wherein the priority constraint identified in the probe message is application specific, and wherein the application comprises at least one of infrastructure monitoring, traffic monitoring, environmental monitoring, and hospital/health care equipment/environment monitoring.

18. An apparatus comprising:
at least one processor; and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least perform or control the following:
sending, by a device of a wireless local area network, an indication of data required to be sent, to an access point of the wireless local area network;
receiving by the device, a probe message from the access point, the probe message identifying a priority constraint, wherein the priority constraint is for determining by the device whether the device may request a resource allocation;
sending, by the device, an acknowledgement to the probe message, the acknowledgment indicating that the device has data to send which meets or exceeds the priority constraint identified in the probe message; and
receiving, by the device from the access point, in response to the acknowledgment, a resource allocation to send the data.

19. The apparatus according to claim 18 , wherein the priority constraint identified in the probe message is associated with a classification comprising at least one of regular reporting, low activity, medium activity, strong activity and malfunction detected.

20. The apparatus according to claim 18 , wherein the priority constraint identified in the probe message comprises at least one of significance level, priority of traffic, and delay tolerance.
