This paper firstly puts forward a two dimensional interworking authentication model between 3GPP and WiMAX. In the proposed model, EAP-AKA method is adopted, and the first registered 3GPP AAA server in home domain (i.e. HPLMN, Home Public Land Mobile Network) takes charge of the responsibility of authentication for 3GPP/WiMAX UE by using authentication vectors (AV) obtained from HSS (Home Subscriber...
This paper is mainly focusing on the dynamic authentication data management for the heterogeneous interworking authentication among WiMAX and 3GPP. The 3GPP AAA server in HPLMN performs the authentication for the 3GPP/WiMAX UE by using the authentication vectors (AV) obtained from HSS. Moreover, when the 3GPP/WiMAX UE leaves and reenters the same PLMN (HPLMN or VPLMN) within its avaliable period of...
Facing the different wireless access networks, this paper has proposed several novel interworking AAA architectures among the 3GPP, WiMax and hotspot wireless LANs. In these architectures, a new entity named standby 3GPP AAA server is defined to cope with the single point failure. Moreover, based on the proposed interworking AAA architectures, a hierarchy AAA scheme is proposed. As a result, the simulation...
An IP multimedia subsystem (IMS) has been specified to provide multimedia services in 3GPP release5. In IP multimedia subsystem, both packet-switch domain and IMS authentications are necessary for the IMS subscriber. The IMS authentication is carried out by IMS authentication and key agreement (AKA). It is inefficient that there are so many steps in IMS AKA. Hence, this paper proposes an improved...
