  1. WLAN與3G網路之間 通道轉換之研究 Speaker: Kai-Hsiu Chen Advisor: Jyh-Cheng Chen 2006/1/8

  2. Protocol stack between WLAN UE and 3GPP core network 3GPP TS 23234 , TS 33234

  3. Mapping between E2E tunnel and GTP tunnel 3GPP TS 23234

  4. Patent Goals • IP QoS integration • Minimize changes • PDP context re-use • Parameters mapping • Minimize the inter-system handoff delay

  5. Integrated QoS architecture over COPS

  6. Interworking procedure over Gn' - Tunnel establishment procedure (1/3) WLAN UE TTG GGSN 3GPP AAA-Serv HSS/ HLR PCF 1. IKE_SA_INIT [Headers, Sec.Associations, D-H values, Nonces] 2. Mapping of SDP parameters into DiffServ IP header 3. IKE_AUTH Request [QoS class in IP header] [Header, User ID, Configuration Payload, Sec. Associations, Traffic selectors, W-APN] 4. Access-Request/Identity [User ID, W-APN] 5. Check in user’s subscription if tunnel is allowed. User profile and AVs retrieval if needed 6. EAP-Request/AKA(SIM)-Challenge 7. IKE_AUTH Response [Header, PDG ID, Certificate, AUTH, EAP-Request/AKA(SIM)-Challenge]

  7. Interworking procedure over Gn' - Tunnel establishment procedure (2/3) WLAN UE TTG GGSN 3GPP AAA-Serv HSS/ HLR PCF 8. IKE_AUTH Request [Header, EAP-Response/AKA(SIM)-Challenge] 9.EAP-Response/AKA(SIM)-Challenge 10.EAP-Success + keying material 11. AUTH payload is computed using the keying material (MSK) 12.IKE_AUTH Response [Header, EAP-Success] 13.IKE_AUTH Request [AUTH] 14. Mapping of DiffServ IP header into UMTS QoS 15.Create PDP context request

  8. Interworking procedure over Gn' - Tunnel establishment procedure (3/3) WLAN UE TTG GGSN 3GPP AAA-Serv HSS/ HLR PCF 16. COPS REQ 17. Process authorization request 18. COPS DEC 19. Policy Enforcement 20. COPS RPT 21.Create PDP context response 22.IKE_AUTH Response [QoS class in IP header] [Header, AUTH, Configuration Payload, Sec.Associaitions, Traffic selectors]

  9. QoS mapping • GRX : A kind of PLMN backbone 3GPP TR 23 836
