Method and mechanism to assign a unique identifier to a station from an access point
An access point can track a station throughout a network using an identifier, for example, a media access control (MAC) address. However, as MAC addresses are randomized or changing, there is a need for the access point to provide a unique identifier to a station that does not rely on a MAC address. The access point can receive a unique identifier query response action frame from the station that indicates that the station is associated with a corresponding unique identifier for the network and based on the unique identifier query response action frame, send a unique identifier set action frame to the station so as to cause the station to set as the unique identifier for the station the unique identifier of the unique identifier set action frame sent by the access point.
1 . A method for an access point of a network to provide a unique identifier to a station, the method comprising:
receiving a unique identifier query response action frame from the station that indicates whether the station is associated with a corresponding unique identifier for the network; and
sending a unique identifier set action frame to the station based on the unique identifier query response action frame, wherein the unique identifier set action frame provides the unique identifier to the station;
send a unique identifier query request action frame to the station;
wherein the sending the unique identifier query request action frame is after expiration of a response time period.
2 . The method of claim 1 , further comprising:
receiving a unique identifier query response action frame from the station.
3 . The method of claim 1 , wherein the unique identifier query response action frame is unsolicited.
4 . The method of claim 1 , wherein the unique identifier set action frame contains a duration of time associated with the unique identifier.
5 . The method of claim 1 , further comprising:
receiving a subsequent unique identifier query response action frame from the station that indicates the unique identifier previously set by the network, wherein the unique identifier is based on the unique identifier set action frame; and
determining that the unique identifier remains valid for the network.
6 . An access point of a network to provide a unique identifier to a station, the access point comprising:
a memory; and
a processor configured to execute one or more instructions stored on the memory to cause the access point to:
receive a unique identifier query response action frame from the station that indicates whether the station is associated with a corresponding unique identifier for the network; and
send a unique identifier set action frame to the station based on the unique identifier query response action frame, wherein the unique identifier set action frame provides the unique identifier to the station;
send a unique identifier query request action frame to the station;
wherein the sending the unique identifier query request action frame is after expiration of a response time period.
7 . The access point of claim 6 , wherein the process is further configured to execute the one or more instructions to further cause the access point to:
receive a unique identifier query response action frame from the station.
8 . The access point of claim 6 , wherein the unique identifier query response action frame is unsolicited.
9 . The access point of claim 6 , wherein the unique identifier set action frame contains a time duration of time associated with the unique identifier.
10 . The access point of claim 6 , wherein the process is further configured to execute the one or more instructions to further cause the access point to:
receive a subsequent unique identifier query response action frame from the station that indicates the unique identifier previously set by the network, wherein the unique identifier is based on the unique identifier set action frame; and
determine that the unique identifier remains valid for the network.
11 . A non-transitory, computer-readable medium of an access point storing one or more computer-readable instructions for providing a unique identifier to a station that when executed by a processor, cause the processor to perform one or more operations comprising:
receiving a unique identifier query response action frame from the station that indicates whether the station is associated with a corresponding unique identifier for the network; and
sending a unique identifier set action frame to the station based on the unique identifier query response action frame, wherein the unique identifier set action frame provides the unique identifier to the station;
sending a unique identifier query request action frame to the station;
wherein the sending the unique identifier set action frame is after expiration of a response time period.
12 . The non-transitory, computer-readable medium of claim 11 , wherein the one or more computer-readable instructions when executed by a processor, further cause the processor to perform one or more operations further comprising:
receiving a unique identifier query response action frame from the station.
13 . The non-transitory, computer-readable medium of claim 11 , wherein at least one of:
the unique identifier query response action frame is unsolicited; and
the unique identifier set action frame contains a duration of time associated with the unique identifier.
14 . The non-transitory, computer-readable medium of claim 11 , wherein the one or more computer-readable instructions when executed by a processor, further cause the processor to perform one or more operations further comprising:
receiving a subsequent unique identifier query response action frame from the station that indicates the unique identifier previously set by the station, wherein the unique identifier is based on the unique identifier set action frame; and
determining that the unique identifier remains valid for the network.
