System and method for tight inter-working between wireless local area network (WLAN) and universal mobile telecommunication systems (UMTS)
First Claim
1. A method providing tight inter-working between a wireless local area network (WLAN) and a universal mobile telecommunications system (UMTS), comprising:
- said UMTS and WLAN communicating data directly using mobile internet protocol (MIP) between said UMTS and said WLAN; and
said UMTS and WLAN communicating data through the internet using internet protocol (IP).

Abstract
In a system having a PLMN and a WLAN IP GW, an Iur interface providing handover between a PLMN and the WIP-GW. Mobile internet protocol (Mobile IP) provides session management and data tunneling between the PLMN (home agent) and the WLAN. The WIP-GW functions as the foreign agent toward the PLMN. Services are provided by the PLMN MIP over DIAMETER for registration, authentication and subscriber management, working into the HLR/HSS and the CGF in the PLMN. The use of a single architecture to support the loose inter-working scenarios is such that the architecture minus the Iur interface and MIP becomes a loose inter-working architecture. The UMTS PLMN billing platform is made via the DIAMETER/UMTS inter-working. Authentication is provided by the UMTS PLMN HSS/HLR. The architecture concept can be broadened to cover the inter-working of other access technologies with UMTS.
