Network address policy information received in a pre-associated state
In some examples, a wireless device includes a communication interface to communicate with a wireless network, and at least one processor configured to, receive, from an access point (AP), information including a network address policy of the wireless network. The at least one processor is configured to further, in response to the information including the network address policy, use an address of the wireless device according to the network address policy.
1. A wireless device comprising:
a storage medium; and
one or more processors coupled to the storage medium, the one or more processors configured to:
receive an Access Network Query Protocol (ANQP) message from an access point (AP), wherein the ANQP message comprises information of a wireless network including a network address policy of the wireless network, and the network address policy governs setting of a Medium Access Control (MAC) address for the wireless device; and
in response to the information including the network address policy, use an address of the wireless device according to the network address policy.
2. The wireless device of claim 1 , wherein the information including the network address policy is settable to one of a plurality of values to indicate one of a plurality of different network address policies.
3. The wireless device claim 2 , wherein the plurality of values comprise a first value indicating use of the address of the wireless device with at least a portion of the address assigned according to a Structured Local Address Plan (SLAP).
4. The wireless device of claim 3 , wherein the first value indicates that a second portion of the address of the wireless device is one of randomly assigned, assigned according to another standard, or assigned by a network administrator.
5. The wireless device of claim 3 , wherein the plurality of values further comprise a second value indicating use of a random address of the wireless device.
6. The wireless device of claim 3 , wherein the plurality of values further comprise a second value indicating use of a global address of the wireless device.
7. The wireless device of claim 1 , wherein the information including the network address policy is contained in a wireless local area network (WLAN) discovery message.
8. The wireless device of claim 1 , wherein the ANQP message is received when the wireless device is in a pre-associated state.
9. The wireless device of claim 1 , wherein the one or more processors are further configured to receive a beacon containing information including a network address policy.
10. The wireless device of claim 1 , wherein the one or more processors are further configured to receive a probe response containing information including a network address policy.
11. The wireless device of claim 1 , wherein the one or more processors are further configured to:
in response to the information including the network address policy, send a request to the AP; and
receive, from the AP in response to the request, further information about the network address policy,
wherein the address of the wireless device according to the network address policy that is used is based on the further information.
12. The wireless device of claim 1 , wherein the one or more processors are further configured to:
receive, from a network node, an indication that the address of the wireless device is a duplicate of another address already used in the wireless device or the wireless network.
13. An access point (AP), comprising:
one or more processors configured to send, to a wireless device, an Access Network Query Protocol (ANQP) message comprising information including a network address policy of a wireless network, to cause the wireless device to use an address of the wireless device according to the network address policy, wherein the network address policy governs setting of a Medium Access Control (MAC) address for the wireless device.
14. The AP of claim 13 , wherein the information including the network address policy is settable to one of a plurality of values to indicate one of a plurality of different network address policies.
15. The AP of claim 14 , wherein the plurality of values comprise a first value indicating use of the address of the wireless device with a first portion of the address of the wireless device assigned according to an Institute of Electrical and Electronics Engineers (IEEE) 802c-2017 standard, and a second portion of the address of the wireless device randomly assigned.
16. The AP of claim 14 , wherein the plurality of values comprise a first value indicating use of the address of the wireless device with a first portion of the address assigned according to an Institute of Electrical and Electronics Engineers (IEEE) 802c-2017 standard, and a second portion of the address of the wireless device assigned by another standard.
17. The AP of claim 14 , wherein the plurality of values comprise a first value indicating use of the address with a first portion of the address of the wireless device assigned according to an Institute of Electrical and Electronics Engineers (IEEE) 802c-2017 standard, and a second portion of the address of the wireless device assigned by a network administrator.
18. The AP of claim 14 , wherein the plurality of values comprise a first value indicating use of the address of the wireless device with at least a portion of the address assigned according to a Structured Local Address Plan (SLAP).
19. The AP of claim 18 , wherein the first value indicates that a second portion of the address of the wireless device is one of randomly assigned, assigned according to another standard, or assigned by a network administrator.
20. The AP of claim 13 , further comprising:
responsive to a determination that the address of the wireless device is duplicative of an address used by another wireless device, sending, to the wireless device or the another wireless device, a duplicated address indication.
