Abstract
A method of determining availability of a connection between a wireless local area network and a home network of a mobile user device prior to initiating connection or authentication comprises selecting a network device; and sending a probe signaling message comprising a user device to the selected network device. The network device uses this home identifier data to formulate a signaling message that it sends towards the appropriate home network to contract a home authentication server. An indication to the user device of the result of the attempt is returned.

9. A method of determining availability of a network connection between a public wireless local area network and a home network of a mobile user device, the method comprising:
-
sending a signaling message in parallel from the user device to a plurality of network devices, each network device being associated with a public wireless local area network, the signaling message including a home identifier that identifies the home network of the user device; formulating a protocol signaling message at each network device using the home identifier; for each protocol signaling message, attempting to send the protocol signaling message from the network device to the home network to test availability of a relationship between the network device and the home network; and if a network connection is available between the public wireless local area network and the home network, returning an indication of availability to the user device, the indication of availability being returned before the user device attempts to initiate or authenticate the connection. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
