Abstract: Systems and methods for tracking the privacy policy of an electronic device in a network having a privacy policy server and an authentication server are provided. In one aspect a privacy policy server receives a connection request from the electronic device, queries an authentication server for the device's privacy policy acceptance state. If the device had not accepted the network's privacy policy, the privacy policy server sends a URL to the device so the device may accept or reject the policy. The authentication server locates a network session identifier representing the device's connection with the network and response to the policy server indicating the device's current privacy policy acceptance state if applicable. Advantageously, a network session identifier can track a device's privacy policy acceptance state when the device reconnects with the network. The systems and methods are applicable in wireless networks, such as 802.11.

Abstract: According to a first aspect of the disclosure, methods are discussed in which a station (STA) sends a message to an access point, for example an associated access point, about a change in multi-AP coordination parameters. A STA, which may be a mobile STA, can be in a better position than the APs themselves, for detecting changes in conditions which can affect the effectiveness, or even the desirability of the multi-AP coordination. Accordingly the STA can send a message reporting detected conditions related to multi-AP coordination. In some embodiments, such a message can request for initializing multi-AP coordination, such a message can be in response to a triggering event detected by the STA. In response to such a triggering event, the STA can analyze the STA's service needs, and send the message about a change in multi-AP coordination parameters. A second aspect of the disclosure provides an AP-to-AP negotiation process for multi-AP coordination.
