A generic way for wireline and wireless access authentication

With the developments of broadband wireless techniques, one thing we can be sure is that multi access methods (e.g. GPRS, Bluetooth, IEEE 801.11) would coexist together in the access field in the future and IP could provide a simple unique platform for convergence of different techniques. Based on the analysis of different authentication methods (ppp, 802.x) now exist in this field, the paper proposes an IP carrier based authentication method which support smooth interaction between mobile terminals and access networks while roaming, and also provides the original model of the implementation based on ICMP/IP.
