1. 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. 2 Protocol stack between WLAN UE and 3GPP core network 3GPP TS 23234, TS 33234

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

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

5. 5 Integrated QoS architecture over COPS

6. 6 Interworking procedure over Gn' - Tunnel establishment procedure (1/3) WLAN UE TTG 3GPP AAA-Serv HSS/ HLR 1. IKE_SA_INIT [Headers, Sec.Associations, D-H values, Nonces] 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] GGSN PCF 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]

7. 7 Interworking procedure over Gn' - Tunnel establishment procedure (2/3) 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] WLAN UE TTG 3GPP AAA-Serv HSS/ HLR GGSN 15.Create PDP context request PCF 8. IKE_AUTH Request [Header, EAP-Response/AKA(SIM)-Challenge] 14. Mapping of DiffServ IP header into UMTS QoS
