Configurator forced client network rejoining
View Patent ↗A collocated device functioning as a configurator can use short and long button activations to enter a configuration state, open a timing window, and force client devices currently joined to a network to rejoin the network. If the collocated device functioning as a configurator is unconfigured, a short (or long) button activation can initiate a configuration sequence. A short button activation on that same collocated device, once configured, can cause the device to open a configurator timing window, during which one or more devices can be provided the information necessary to securely communicate on a network. A long (or short) button activation can be used to force all currently connected client devices, or rejoin the network using a new Service Set Identifier (SSID) or passphrase.
1. A configurator station comprising:
a configuration processor;
persistent memory coupled to the configuration processor and configured to store configuration information pertaining to previously configured client stations;
a button capable of being activated, wherein a time duration for which the button is activated corresponds to a first-duration button activation or a second-duration button activation;
the configuration processor configured to open a configurator timing window in response to the first-duration button activation; and
the configuration processor configured to release, from the persistent memory, the configuration information pertaining to previously configured client stations in response to the second-duration button activation.
2. The configurator station of claim 1 , wherein the configuration processor is further configured to generate either, or both of, a new Service Set Identifier (SSID) and a new passphrase in response to the second duration button activation.
3. The configurator station of claim 1 , wherein:
the first-duration button activation corresponds to one of a short button activation and a long button activation; and
the second-duration button activation corresponds to the other one of the short button activation and the long button activation.
4. The configurator station of claim 1 , wherein a length of time the configurator timing window remains open is configurable.
5. The configurator station of claim 1 , wherein the configuration processor is further configured to:
generate a first beacon frame including authentication enablement information to be transmitted during a time interval when the configurator timing window is open; and
generate a second beacon frame that does not include authentication enablement information to be transmitted during a time interval when the configuration timing window is closed.
6. The configurator station of claim 5 , wherein the authentication enablement information includes a flag indicating whether a client station has been configured during a current configurator timing window.
7. The configurator station of claim 6 , wherein the configuration processor is further configured to disallow configuration of more than one client station during the current configurator timing window.
8. A collocated device functioning as a configurator, the collocated device comprising:
a processor;
non-volatile memory coupled to the processor;
a button capable of being activated, wherein a time duration for which the button is activated corresponds to a short button activation or a long button activation;
during a time when the collocated device is an unconfigured collocated device, the processor initiates configuration of the collocated device in response to the short button activation; and
after the collocated device is configured, the processor opens a configurator timing window in response to the short button activation.
9. The collocated device of claim 8 , wherein the processor releases configuration information pertaining to previously configured client stations in response to the long button activation.
10. The collocated device of claim 8 , wherein the configuration includes obtaining either or both of a Service Set Identifier (SSID) and a passphrase to subsequently be utilized when configuring client stations.
11. The collocated device of claim 10 , wherein the processor is further configured to obtain either or both of the SSID and the passphrase using manual entry.
12. The collocated device of claim 10 , wherein the processor is further configured to generate either or both of the SSID and the passphrase.
13. The collocated device of claim 8 , wherein the processor is further configured to:
generate a first beacon frame including authentication enablement information to be transmitted during a time interval when the configurator timing window is open; and
generate a second beacon frame that does not include authentication enablement information to be transmitted during a time interval when the configuration timing window is closed.
14. The collocated device of claim 13 , wherein the authentication enablement information includes a flag indicating whether a client station has been configured during a current configurator timing window.
15. The collocated device of claim 14 , wherein the configuration processor is further configured to disallow configuration of more than one client station during the current configurator timing window.
16. A system comprising:
a wireless access point;
a configurator collocated with the wireless access point, the configurator comprising:
a configuration processor;
memory coupled to the configuration processor and configured to store configuration information pertaining to previously configured client stations;
a button capable of being activated, wherein a time duration for which the button is activated corresponds to a first-duration button activation or a second-duration button activation;
in response to the first-duration button activation during a time when the configurator has been configured, the processor opens a configurator timing window; and
in response to the second-duration button activation, the processor forces previously configured client stations to repeat an authentication process to regain an ability to engage in secure wireless communications.
17. The system of claim 16 , wherein the processor, in response to the second-duration button activation, releases the configuration information pertaining to previously configured client stations from the memory.
18. The system of claim 17 , wherein the processor obtains either, or both of, a new Service Set Identifier (SSID) and a new passphrase in response to the second duration button activation.
19. The system of claim 16 , wherein in response to the first-duration button activation during a time when the configurator is unconfigured, the processor initiates configuration of the configurator in response to the short button activation.
20. The system of claim 16 , wherein the processor is further configured to:
generate a first beacon frame including a flag indicating whether a client station has been configured during a current configurator timing window; and
if the flag indicates that a first client station has been configured, disallow configuration of a second client station during the current configurator timing window.
