Efficient Mechanism for the Setup of Ue-initiated Tunnels in 3gpp-wlan Interworking
نویسنده
چکیده
We propose an efficient mechanism for the setup of UE(User Equipment)initiated tunnels in 3GPP(3rd Generation Project Partnership)-WLAN(Wireless Local Area Network) interworking. The proposed mechanism is based on a secret key which is pre-distributed in the process of authentication and key agreement between UE and 3GPP AAA(Authentication Authorization Accounting) server. Therefore it can avoid modular exponentiation and public key signature which need a large amount of computation in UE. Also the proposed scheme provides mutual authentication and session key establishment between UE and PDG(Packet Data Gateway).

متن کاملEnd-to-End QoS Guaranteed Service in WLAN and 3GPP Interworking Network
In this paper, we model the end-to-end QoS provisioning mechanisms in the WLAN and 3GPP interworking network. For the end-to-end QoS guaranteed service, we model the control plane and user plane considering the WLAN and 3GPP interworking network. And we propose the QoS parameter/class mapping and DPS packet scheduler. By the simulation results, DPS can provide the low end-to-end delay of voice ...
