Abstract

A method for accelerating provisioning of wireless device. The method comprises receiving, by an access point (AP), a mapping of a wireless device and a further AP from a server. The method further comprises receiving, by the AP, presence announcement information from the wireless device. The method further comprises transmitting, by the AP and based on the received mapping, the received presence announcement information to the further AP. The method further comprises receiving, by the AP, response information for the wireless device from the further AP, the response information including an authentication request for the wireless device. The method further comprises transmitting, by the AP, the response information to the wireless device. In this manner, the provisioning ability of the provision AP can be extended to the non-provision AP, the provisioning time can be reduced, and the provisioning process can be accelerated.

First claim

What is claimed is:

1 . An access point (AP) comprising:
at least one processor; and a memory coupled to the at least one processor, the memory storing instructions to cause the at least one processor to:
receive a mapping of a wireless device and a further AP from a server, the mapping indicating that the further AP is a provision AP for the wireless device;
receive presence announcement information from the wireless device;
transmit, based on the received mapping, the received presence announcement information to the further AP;
receive response information for the wireless device from the further AP, the response information including an authentication request for the wireless device; and
transmit the response information to the wireless device.

2 . The AP of claim 1 , wherein the memory further stores instructions to cause the at least one processor to:
after receiving the presence announcement information from the wireless device, determine that a mapping of the wireless device and the further AP does not exist; and transmit, to the server, a request to be a provision AP for the wireless device.

3 . The AP of claim 2 , wherein the memory further stores instructions to cause the at least one processor to:
receive the mapping of the wireless device and the further AP from the server without being selected as a provision AP for the wireless device; and transmit, based on the received mapping, the received presence announcement information to a switch connected to the further AP.

4 . The AP of claim 1 , wherein the wireless device is a first wireless device, the presence announcement information is first presence announcement information, and the memory further stores instructions to cause the at least one processor to:
receive second presence announcement information from a second wireless device; determine that a mapping of the second wireless device and a provision AP for the second wireless device does not exist; and transmit, to the server, a request to be the provision AP for the second wireless device.

5 . The AP of claim 4 , wherein the memory further stores instructions to cause the at least one processor to:
receive, from the server, provision data for provisioning the second wireless device; and cache the received provision data.

6 . The AP of claim 5 , wherein the AP is a first AP, the further AP is a second AP, and the memory further stores instructions to cause the at least one processor to:
receive the second a from a third AP; determine a signal strength of a signal received from the third AP; select the third AP as a temporary communicating AP for the second wireless device based on the signal strength of the signal; and transmit the cached provision data as response information to the third AP.

7 . The AP of claim 6 , wherein the instructions to select the third AP as a temporary communicating AP for the second wireless device comprise instructions to cause the at least one processor to:
compare the signal strength of the signal received from the third AP; and in response to determining that the signal strength is greater than a threshold value, select the third AP as the temporary communicating AP for the second wireless device.

8 . The AP of claim 1 , wherein the wireless device accesses a network via a Device Provisioning Protocol, and the presence announcement information is DPP presence announcement information.

9 . A server comprising:
at least one processor; and a memory coupled to the at least one processor, the memory storing instructions to cause the at least one processor to:
receive, from a first access point (AP), a request to be a provision AP for a wireless device;
determine that the wireless device does not have a provision AP;
select the first AP as the provision AP for the wireless device;
generate a mapping of the wireless device and the first AP; and
transmit the mapping of the wireless device and the first AP to a second AP, the mapping being used by the second AP for authenticating the wireless device through the first AP.

10 . The server of claim 9 , wherein the memory further stores instructions to cause the at least one processor to:
transmit provision data for provisioning the wireless device to the first AP.

11 . The server of claim 10 , wherein the instructions to transmit the mapping of the wireless device and the first AP to the second AP comprise instructions to cause the at least one processor to:
obtain a neighbor AP list for the first AP; and transmit the mapping of the wireless device and the first AP based on the neighbor AP list.

12 . The server of claim 9 , wherein the memory further stores instructions to cause the at least one processor to:
receive, from a third AP, a request to be the provision AP for the wireless device; determine that the wireless device has the provision AP based on the mapping of the wireless device and the first AP; and transmit the mapping of the wireless device and the first AP to the third AP without selecting the third AP as the provision AP.

13 . A method comprising:
receiving, by an access point (AP), a mapping of a wireless device and a further AP from a server, the mapping indicating that the further AP is a provision AP for the wireless device; receiving, by the AP, presence announcement information from the wireless device; transmitting, by the AP and based on the received mapping, the received presence announcement information to the further AP; receiving, by the AP, response information for the wireless device from the further AP, the response information including an authentication request for the wireless device; and transmitting, by the AP, the response information to the wireless device.

14 . The method of claim 13 , wherein the method further comprises:
determining, by the AP, that a mapping of the wireless device and the further AP does not exist; and transmitting, by the AP and to the server, a request to be a provision AP for the wireless device.

15 . The method of claim 14 , wherein the method further comprises:
receiving, by the AP, the mapping of the wireless device and the further AP from the server without being selected as a provision AP for the wireless device; and transmitting, by the AP, based on the received mapping, the received presence announcement information to a switch connected to the further AP.

16 . The method of claim 13 , wherein the wireless device is a first wireless device, the presence announcement information is first presence announcement information, and the method further comprises:
receiving, by the AP, second presence announcement information from a second wireless device; determining, by the AP, that a mapping of the second wireless device and a provision AP for the second wireless device does not exist; and transmitting, by the AP and to the server, a request to be the provision AP for the second wireless device.

17 . The method of claim 16 , wherein the method further comprises:
receiving, by the AP and from the server, provision data for provisioning the second wireless device; and caching, by the AP, the received provision data.

18 . The method of claim 17 , wherein the AP is a first AP, the further AP is a second AP, and the method further comprises:
receiving, by the AP, the second presence announcement information from a third AP; selecting, by the AP, the third AP as a temporary communicating AP for the second wireless device; and transmitting, by the AP, the cached provision data as response
