Abstract
A system may be configured to: obtain one or more attributes of an RF environment of a user device; detect that the user device is neither associated with any AP nor authenticated; after the detection, stimulating the user device to be associated with at least one AP and authenticated to respond to an RTS PDU with a CTS PDU; receive the CTS PDU; and after the reception, adjust an RF link with which the user device is currently connected to operate at one or more different frequencies.
Claims18
A computer-implemented method, comprising:
- obtaining one or more attributes of a radiofrequency (RF) environment of a user device;
- detecting that the user device is neither associated with any access point (AP) nor authenticated;
- after the detection, stimulating the user device to be (i) associated with at least one AP and (ii) authenticated to respond to a ready-to-send (RTS) protocol data unit (PDU) with a clear-to-send (CTS) PDU;
- receiving the CTS PDU;
- after the reception, adjusting an RF link with which the user device is currently connected to operate at one or more different frequencies;
- and
- obtaining, from the user device, a first probe request indicating non-association, the first probe request comprising an extractable service set identification (SSID) of the at least one AP.
4 more elements
A computer-implemented method, comprising:
- obtaining one or more attributes of an RF link communicably involving a user device;
- detecting that the user device is currently neither associated with any AP nor authenticated;
- determining that a MAC address of the user device is predetermined to be of interest;
- and
- after the determination, stimulating the user device to be (i) associated with at least one AP and (ii) authenticated at least by emitting an unsolicited authentication response causing the user device to transition to a state configured to operably respond to an RTS PDU.
2 more elements
A computer-implemented system, comprising:
- a non-transitory memory including instructions stored;
- a processor operably coupled to the non-transitory memory and configured to execute one or more of the stored instructions comprising:
- obtaining one or more attributes of a radiofrequency (RF) environment of a user device;
- detecting that the user device is neither associated with any access point (AP) nor authenticated wherein the detection includes obtaining, from the user device, a first probe request indicating non-association, and wherein the first probe request comprises an extractable service set identification (SSID) of the at least one AP;
- after the detection, stimulating the user device to be (i) associated with at least one AP and (ii) authenticated to respond to a ready-to-send (RTS) protocol data unit (PDU) with a clear-to-send (CTS) PDU;
- receiving the CTS PDU;
- and
- adjusting an RF link with which the user device is currently connected to operate at one or more different frequencies after the reception.
