Generation of a unique device identifier for a client device in a wireless network
To improve the network experience in a network, a unique device identifier (UDID) can be generated by a UDID generation module of a client device. The UDID generation module utilizes one or more device parameters as well as a service set identifier (SSID) as input(s) to the UDID generation module. The UDID can be reported to an access point device of the network so that the access point device can track, monitor, control, etc. the client device within the network, for example, when media access control randomization (rMAC) is utilized by the network to protect the privacy of the client device or a user of the client device. The same UDID is generated each time the client device joins the network so that the client device need not store the UDID.
1. A method for an access point device within a network to receive a unique device identifier (UDID) from a client device, the method comprising:
providing the client device with a service set identifier (SSID);
sending a UDID request to the client device; and
receiving a UDID report message from the client device of the network in response to the UDID request, wherein the UDID report message comprises a number of bits of a UDID generated by the client device based on the SSID as the UDID, wherein the UDID report message indicates that the client device is providing the UDID to the access point device.
2. The method of claim 1 , further comprising:
enforcing one or more policies against the client device based on the UDID report message.
3. The method of claim 1 , wherein the UDID report message comprises any of an identification of a length of the UDID to be associated with the client device, the UDID that is to be associated with the client device, one or more manufacturer specific parameters, or any combination thereof.
4. The method of claim 1 , further comprising:
sending an action frame exchange to the client device; and
wherein the UDID report message is based on the action frame exchange.
5. The method of claim 1 , further comprising:
monitoring the client device based on the UDID and a media access control (MAC) address of the client device currently in use for a network session.
6. The method of claim 1 , further comprising:
storing the UDID report message in a memory of the access point device, a cloud resource, or both.
7. The method of claim 1 , further comprising:
sending one or more device parameters to the client device, wherein the UDID is based on the one or more device parameters.
8. An access point device within a network to receive a unique device identifier (UDID) from a client device, the access point device comprises:
a memory storing one or more computer-readable instructions; and
a processor connected to the memory, the processor configured to execute the one or more computer-readable instructions to:
provide the client device with a service set identifier (SSID);
send a UDID request to the client device; and
receive a UDID report message from the client device of the network in response to the UDID request, wherein the UDID report message comprises a number of bits of a UDID generated by the client device based on the SSID as the UDID, wherein the UDID report message indicates that the client device is providing the UDID to the access point device.
9. The access point device of claim 8 , wherein the processor is further configured to execute the one or more instructions to:
enforce one or more policies against the client device based on the UDID report message.
10. The access point device of claim 8 , wherein the UDID report message comprises any of an identification of a length of the UDID to be associated with the client device, the UDID that is to be associated with the client device, one or more manufacturer specific parameters, or any combination thereof.
11. The access point device of claim 8 , wherein the processor is further configured to execute the one or more instructions to:
send an action frame exchange to the client device; and
wherein the UDID report message is based on the action frame exchange.
12. The access point device of claim 8 , wherein the processor is further configured to execute the one or more instructions to:
monitor the client device based on the UDID and a media access control (MAC) address of the client device currently in use for a network session.
13. The access point device of claim 8 , wherein the processor is further configured to execute the one or more instructions to:
store the UDID report message in the memory of the access point device, a cloud resource, or both.
14. The access point device of claim 8 , wherein the processor is further configured to execute the one or more instructions to:
send one or more device parameters to the client device, wherein the UDID is based on the one or more device parameters.
15. A non-transitory computer readable medium of an access point device having one or more computer-readable instructions stored thereon, that when executed by a processor cause the access point device to perform one or more operations comprising:
providing the client device with a service set identifier (SSID);
sending a UDID request to the client device; and
receiving a UDID report message from the client device of the network in response to the UDID request, wherein the UDID report message comprises a number of bits of a UDID generated by the client device based on the SSID as the UDID, wherein the UDID report message indicates that the client device is providing the UDID to the access point device.
16. The non-transitory computer-readable medium of claim 15 , wherein the one or more computer-readable instructions further cause the access point device to perform one or more further operations comprising:
enforcing one or more policies against the client device based on the UDID report message.
17. The non-transitory computer-readable medium of claim 15 , wherein the UDID report message comprises any of an identification of a length of the UDID to be associated with the client device, the UDID that is to be associated with the client device, one or more manufacturer specific parameters, or any combination thereof.
18. The non-transitory computer-readable medium of claim 15 , wherein the one or more computer-readable instructions further cause the access point device to perform one or more further operations comprising:
sending an action frame exchange to the client device; and
wherein the UDID report message is based on the action frame exchange.
19. The non-transitory computer-readable medium of claim 15 , wherein the one or more computer-readable instructions further cause the access point device to perform one or more further operations comprising at least one of:
monitoring the client device based on the UDID and a media access control (MAC) address of the client device currently in use for a network session; and
storing the UDID report message in a memory of the access point device, a cloud resource, or both.
20. The non-transitory computer-readable medium of claim 15 , wherein the one or more computer-readable instructions further cause the access point device to perform one or more further operations comprising:
sending one or more device parameters to the client device, wherein the UDID is based on the one or more device parameters.
