摘要： In one embodiment, a method includes identifying, responsive to a triggering event, one or more radio frequency (RF) firewall transceivers that neighbor a data wireless access point to which a given wireless client is communicating; configuring one or more of the identified neighboring RF firewall transceivers to detect RF frames transmitted by the wireless client; causing the data wireless access point to transmit one or more wireless messages operative to cause the wireless client to transmit RF frames; collecting RF signal data corresponding to the RF frames transduced by one or more of the identified neighboring RF firewall transceivers; transmitting the collected RF signal data to a location system; receiving from the location system an indication of the location of the wireless client; and applying one or more network access policies based on the indication of the location.

摘要： Methods and apparatus for enabling mobility of a node that does not support Mobile IP are disclosed. Access point information is maintained for all functioning access points. In accordance with one embodiment, an authoritative access point (AAP) maintains access point information for all functioning access points (APs) and sends updates for all additions or other modifications to the continually changing access point information to enable APs to store a local copy of the AP information. For instance, when an AP goes offline, the access point information for that AP will be removed from the set of access point information, and notification of this removal is sent to other APs so that the local copy of the AP information may be similarly updated. As another example, when an AP comes online, it will send its AP information to the AAP. The AAP will store the AP information and provide this new AP information to other “active” APs. The AP information preferably includes an AP subnet and a gateway. When an AP receives a data packet, the AP may compare the data packet (e.g., source address) with the AP information (e.g., AP subnet) for one or more APs to determine whether to send a registration request on behalf of the node. For instance, the registration request may specify the gateway as the node's Home Agent.

摘要： Methods and apparatus for enabling mobility of a node that does not support Mobile IP are disclosed. When an AP receives a data packet, the AP may compare the data packet (e.g., source address) with the AP information for one or more APs to determine whether to send a registration request on behalf of the node. More particularly, the AP determines from the source address whether the node is located on a subnet identical to a subnet of the AP. If the node is located on the subnet of the AP, no Mobile IP service is required on behalf of the node. However, when it is determined from the source address that the node is not located on the subnet identical to the subnet of the Access Point, the AP composes and sends a mobile IP registration request on behalf of the node. For instance, the mobile IP registration request may be composed using the gateway associated with the “home” AP (e.g., having a matching subnet) as the node's Home Agent.
