Techniques for Roaming Between Heterogeneous Wireless Networks

摘要

Examples are disclosed for roaming between heterogeneous wireless networks. In some examples, an authorization request for user equipment (UE) to access a visited wireless local area network (WLAN) may be received via a first protocol. The authorization request may be interworked by an authentication, authorization and accounting (AAA) interworking function (AIF) to enable the UE to be authenticated and authorized for access to the visited WLAN via information exchanged between a visited AAA server and a home AAA server. The visited home AAA server may be associated with different types of wireless networks to include wireless wide area networks (WWANs) or with a different WLAN. Interworking by the AIF may include translating the authentication request received via the first protocol to a second protocol to allow for the exchange of information between the visited AAA server and the home AAA server. Other examples are described and claimed.

主权项

1. An apparatus comprising:
a processor circuit; a receive component to be executed by the processor circuit to receive an authorization request for user equipment (UE) to access a visited wireless local area network (WLAN), the authorization request received using a first remote authentication dial in user service (RADIUS) protocol for a wireless roaming intermediary exchange-interconnect (WRIX-i) or international roaming.61 (IR.61) interface; an interworking component to be executed by the processor circuit to interwork the authorization request for the UE to access the visited WLAN via an authentication, authorization and accounting (AAA) interworking function (AIF), interworking via the AIF to authenticate and authorize the UE for access to the visited WLAN via information received from a visited AAA server and information received from a home AAA server, the visited AAA server associated with the visited WLAN and the home AAA server associated with a wireless wide area network (WWAN); and a forwarding component to be executed by the processor circuit to forward the authorization request to the visited AAA server.
