Abstract

The present disclosure relates to simultaneous operation of Wi-Fi access points in a super cell mode and a standalone mode and controlling connectivity of end terminals thereto. In one aspect, a method includes receiving a configuration for a group of access points operating within a network, the configuration allowing each access point of the group to operate in a super cell mode over a shared frequency channel and a standalone mode over a non-shared frequency channel. The method further includes determining, for an end terminal, whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel based on a network policy to yield a determination; and controlling connectivity of the end terminal to at least one access point of the group of access points over the shared frequency channel or the non-shared frequency channel based on the determination.

First claim

What is claimed is:

1. A method, comprising:
receiving, at a network controller, a configuration for a group of access points operating within a network, the configuration allowing each access point of the group to operate simultaneously in a super cell mode over a shared frequency channel and a standalone mode over a non-shared frequency channel to provide connectivity to end terminals in one of the super cell mode or the standalone mode based on a condition, each access point operating over a unique non-shared frequency relative to one or more adjacent access points in the network;
determining, for an end terminal, whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel based on a network policy that corresponds to the condition, to yield a determination; and
controlling connectivity of the end terminal to at least one access point of the group of access points over the shared frequency channel or the non-shared frequency channel based on the determination.

2. The method of claim 1 , wherein the configuration includes a Service Set Identifier (SSID) with which each access point in the group is configured to operate in both the super cell mode and the standalone mode.

3. The method of claim 1 , wherein the network policy specifies a connection mode for each type of end terminal connected to the network, the connection mode being one of the super cell mode or the standalone mode.

4. The method of claim 3 , wherein determining whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel is based on a type of the end terminal.

5. The method of claim 1 , wherein the network policy specifies a connection mode for each type of end terminal connected to the network based on a physical location of a respective end terminal relative to a coverage area of an access point to which the respective end terminal is connected.

6. The method of claim 1 , wherein the network policy specifies a connection mode for each type of application utilized on end terminals connected to the network, the connection mode being one of the super cell mode or the standalone mode.

7. The method of claim 6 , wherein determining whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel is based on a type of an application currently in use on the end terminal.

8. The method of claim 1 , wherein the network policy specifies network conditions based on which connectivity of the end terminal to the at least one access point in the super cell mode or the standalone mode is adjusted.

9. The method of claim 1 , wherein the network is a Wi-Fi network;
the network controller is a Wireless Local Area Network Controller (WLC);
the network controller receives the configuration from an enterprise Digital Network Architecture Controller (DNAC); and
the network controller is communicatively coupled to the group of access points.

10. A network controller, comprising:
one or more memories having computer-readable instructions stored therein; and
one or more processors configured to execute the computer-readable instructions to:
receive a configuration for a group of access points operating within a network, the configuration allowing each access point of the group to operate simultaneously in a super cell mode over a shared frequency channel and a standalone mode over a non-shared frequency channel to provide connectivity to end terminals in one of the super cell mode or the standalone mode based on a condition, each access point operating over a unique non-shared frequency relative to one or more adjacent access points in the network;
determine, for an end terminal, whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel based on a network policy that corresponds to the condition, to yield a determination; and
control connectivity of the end terminal to at least one access point of the group of access points over the shared frequency channel or the non-shared frequency channel based on the determination.

11. The network controller of claim 10 , wherein the configuration includes a Service Set Identifier (SSID) with which each access point in the group is configured to operate in both the super cell mode and the standalone mode.

12. The network controller of claim 10 , wherein the network policy specifies a connection mode for each type of end terminal connected to the network, the connection mode being one of the super cell mode or the standalone mode.

13. The network controller of claim 12 , wherein the network controller is configured to determine whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel is based on a type of the end terminal.

14. The network controller of claim 10 , wherein the network policy specifies a connection mode for each type of end terminal connected to the network based on a physical location of a respective end terminal relative to a coverage area of an access point to which the respective end terminal is connected.

15. The network controller of claim 10 , wherein the network policy specifies a connection mode for each type of application utilized on end terminals connected to the network, the connection mode being one of the super cell mode or the standalone mode.

16. The network controller of claim 15 , wherein network controller is configured to determine whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel is based on a type of an application currently in use on the end terminal.

17. The network controller of claim 10 , wherein the network policy specifies network conditions based on which connectivity of the end terminal to the at least one access point in the super cell mode or the standalone mode is adjusted.

18. The network controller of claim 10 , wherein network is a Wi-Fi network and the network controller is a Wireless Local Area Network Controller (WLC).

19. The network controller of claim 10 , wherein the network controller is configured to receive the configuration from an enterprise Digital Network Architecture Controller (DNAC).

20. The network controller of claim 10 , wherein the network controller is communicatively coupled to the group of access points.
