Abstract

The present disclosure discloses a method and network device for intelligent handling of voice calls from mobile voice client devices. In some embodiments, the network device detects that a load, corresponding to a plurality of client devices associated with an access point, exceeds a particular threshold value. In some embodiments, the network device detects that a call quality for a current ongoing call, corresponding to a first client device associated with an access point, is below a first threshold value. In response, the network device selects a particular client device, of the plurality of client devices associated with the access point, for disassociation with the access point. The network device then causes the particular client device to disassociate with the access point.

First claim

What is claimed is:

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, cause the one or more hardware processors to:
detect that a call quality for a current ongoing call corresponding to a first client device associated with an access point is below a first threshold value, wherein the call quality is determined based on a dropped packet rate for the current ongoing call; and
responsive to detecting that a call quality for the current ongoing call is below the first threshold value:
determine whether a second client device is a voice client on any ongoing voice call;
determine whether the second client device is a non-voice client;
select the second client device associated with the access point for disassociation with the access point responsive to determining that the second client device has a level of data traffic above a second threshold value and that the second client device is not on any current ongoing voice call;
cause the second client device to disassociate with the access point in response to:
the second client device not being on any ongoing voice call a maximum number of disassociations caused for the second client device, performed by a set of access points, has not been reached; and
a total number of voice clients being greater than an upper limit of voice clients; and

refrain from causing the second client device to disassociate with the access point in response to the total number of voice clients being less than a lower limit of voice clients.

2. The medium of claim 1 , wherein the call quality is determined based on one or more of: a detected level of interference or a data throughput level for the current ongoing level.

3. The medium of claim 1 , wherein the second client device is selected for disassociation with the access point responsive to determining that the second client device is not on any current ongoing voice call.

4. The medium of claim 1 , wherein the second client device is selected for disassociation with the access point responsive to determining that the second client device is compliant with an IEEE 802.11 r standard.

5. The medium of claim 1 , wherein causing the second client device to disassociate with the access point responsive to determining that the second client device is compliant with an IEEE 802.11 v standard.

6. The medium of claim 1 , wherein the second client device is selected for disassociation with the access point based on a user role or priority associated with the second client device.

7. The medium of claim 1 , further comprising instructions to cause the one or more hardware processors to cause additional client devices of the plurality of client devices to disassociate with the access point until the call quality for the current ongoing call reaches the first threshold value or until the call quality for the current ongoing call reaches a second threshold value.

8. The medium of claim 1 , wherein the second client device is selected for disassociation with the access point based on signal quality value for a wireless connection between second client device and the access point.

9. The medium of claim 1 , wherein the second client device is selected for disassociation with the access point responsive to determining that a maximum number of disassociations caused for the second client device performed by a set of access points has not been reached.

10. The medium of claim 1 , wherein the second client device is selected for disassociation with the access point based on a location of the second client device.

11. The medium of claim 1 , wherein the second client device is selected for disassociation with the access point based on applications currently executing on the second client device.

12. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, cause the one or more hardware processors to:
detect that a call quality for a current ongoing call corresponding to a first client device associated with an access point is below a first threshold value, wherein the call quality is determined based on a dropped packet rate for the current ongoing call;
responsive to detecting that a call quality for the current ongoing call is below the threshold value:
determine whether a second client device is a voice client on any ongoing voice call;
determine whether the second client device is a non-voice client;
select the second client device associated with the access point for disassociation with the access point; and
cause the second client device to disassociate with the access point in response to:
the second client device not being on any ongoing voice call; a maximum number of disassociations caused for the second client device, performed by a set of access points, has not been reached and
a total number of voice clients being greater than an upper limit of voice clients; and

refrain from causing the second client device to disassociate with the access point in response to the total number of voice clients being less than a lower limit of voice clients wherein the second client device is selected for disassociation with the access point based on applications currently executing on the second client device.

13. The medium of claim 12 , wherein the call quality is determined based on one or more of a detected level of interference or a data throughput level for the current ongoing interference level.

14. The medium of claim 12 , wherein the second client device is selected for disassociation with the access point responsive to determining that the second client device has a level of data traffic above the second threshold value and that the second client device is not on any current ongoing voice call.

15. The medium of claim 12 , wherein the second client device is selected for disassociation with the access point based on a user role or priority associated with the second client device.

16. The medium of claim 12 , wherein the second client device is selected for disassociation with the access point based on applications currently executing on the second client device.

17. A system, comprising:
a processor; and
a memory storing machine readable instructions to cause the processor to:
detect that a call quality for a current ongoing call corresponding to a first client device associated with an access point is below a first threshold value, wherein the call quality is determined based on a dropped packet rate for the current ongoing call;
responsive to detecting that a call quality for the current ongoing call is below the first threshold value:
determine whether a second client device is a voice client on any ongoing voice call;
determine whether the second client device is a non-voice client;
select the second client device associated with the access point for disassociation with the access point:
based on a signal quality value for a wireless connection between the second client device and the access point; and
responsive to determining that a maximum number of disassociations caused for the second client device performed by a set of access points has not been reached;

cause the second client device to disassociate with the access point in response to the second client device not being on any ongoing voice call and a total number of voice clients being greater than an upper limit of voice clients; and
refrain from causing the second client device to disassociate with the access point in response to the total number of voice clients being less than a
