Outline
outline architecture between 3GPP and WLAN systems

  • WLAN system architecture

  • 3GPP-based WLAN Access , Authentication and Authorization

  • User Data Routing and Access to Services

  • 3GPP-Based Charging for WLAN


Wlan system architecture
WLAN system architecture architecture between 3GPP and WLAN systems

  • WLAN terminal

  • Layer 2 distribution network

  • DNS

  • DHCP

  • AAA server / proxy

  • Billing system

  • Http server

  • Gateway NAPT


Wlan system architecture1
WLAN system architecture architecture between 3GPP and WLAN systems


Wlan system architecture 3gpp subscription for wlan
WLAN system architecture architecture between 3GPP and WLAN systems(3GPP Subscription for WLAN)

  • SIM/USIM

  • HSS


3gpp base wlan access authentication and authorization
3GPP-Base WLAN Access Authentication and Authorization architecture between 3GPP and WLAN systems

  • IEEE 802.11i

  • EAP SIM :authentication and key agreement protocol base on GSM

  • EAP AKA :encapsulates the UMTS Authentication and Key Agreement within EAP


User data routing and access to services
User Data Routing and Access to Services architecture between 3GPP and WLAN systems

  • The technical architecture regarding user data routing has not been agreed on in 3GPP

  • IP network selection : W-APN ,similar to the APN parameter used in GPRS

  • PDG : terminates the tunnel and acts as a gateway to the selected remote IP network

  • WAG : implement tunneling

  • Wn , Wp , Wu , W i : data plane

  • Wg , Wm : control plane


User data routing and access to services1
User Data Routing and Access to Services architecture between 3GPP and WLAN systems


3gpp based charging for wlan
3GPP-Based Charging for WLAN architecture between 3GPP and WLAN systems

  • Two different charging methods :

    (1)postpaid

    (2)prepaid :

  • CG : for postpaid , The charging information collection happens via so-callde charging gateway (CG)

  • OCS : online charging system for prepaid
