In a method for authenticating a device on a wireless local area network (WLAN) there is a once-off registration phase in which the device sends registration data in a MO SMS via the mobile network to the authentication system, and the authentication system performs a query to this mobile network to validate the subscriber and resolve the subscriber and device identifiers. The device receives network access information from the authentication system, allowing it to generate network access credentials on an on-going basis. This is permanent unless the registration is revoked due, for example, to the device being stolen. The network access information may be provided by the authentication system generating and signing a unique subscriber certificate during registration, and the device downloading it. The device uses the signed certificate to generate and encrypt the network access credentials for the network access.

Device authentication method and devices

A roaming gateway has at least one IP network interface, and at least one cellular network interface, and inter-working functions for inter-working between a wireless IP network and a cellular network. The inter-working functions communicate with user devices in an IP network according to a machine-level subscribe-and-notify event package protocol for managing handover of mobile devices roaming between IP and cellular networks. They also poll a cellular network for subscriber status on that cellular network in the absence of a mobility event package. The inter-working functions comprise HSS functionality programmed to access data on a HLR of a cellular network and to perform HSS operations using said data. The gateway applies routing policies specific to call types, allowing or disallowing the anchoring of calls originating in either an IP network or a cellular network based on number prefixes. The inter-working functions comprise an application server programmed to communicate with a user device as a client. The server provides a staging point for cellular supplementary services while anchoring calls, retrieving configurations from cellular network elements and applying appropriate routing based on these configurations and the current state of a call.
