ACCESS POINT DETECTION
First Claim
1. A method of determining whether an access point in a wireless communications network is capable of providing network mobility to data sessions, the method comprising a wireless communication device having at least two wireless communications network interfaces, performing the steps of:
- connecting to the access point; and
accessing network mobility data relating to the access point by;
sending a capability discovery message to the access point; and
processing a response received from the access point,wherein the response contains an indication of whether network mobility is available to the wireless communication device.

Abstract
A wireless communications device has network interfaces for accessing cellular data networks and Wi-Fi wireless local area networks. Wi-Fi offload allows data traffic to be moved away from the cellular network to the Wi-Fi network. To avoid any existing data sessions being broken during offload, Proxy Mobile IP (PMIP) must be supported by a Wi-Fi access point and associated Mobile Access Gateway. After Wi-Fi association and authentication, the wireless communication device probes the access point and MAG to determine whether PMIP is supported.
