Abstract:
1. A method for authenticating a WLLAN radio user device in a wireless local area network radio access network (WLAN RAN) using a core network supporting GSM protocols comprising: connecting a Radio Access Controller (RAC), a Radio Link Manager (RLM), and a WLAN Access Point (WLAN AP) to a Home Location Register (HLR) of a said core network; establishing communication of the WLAN radio user device with the WLAN AP and the RLM; authenticating the user device having Multilink Client (MLC) capabilities to the HLR; thereafter attaching the user device to the core network system by: connecting a first datalink tunnel from the MLC to the RLM, and a second datalink tunnel from the RLM to the GGSN packet gateway for a global packet data network; wherein the RAC provides protocol stacks and interworking functions to allow the MLC to talk to the HLR.
