Abstract
The paper proposes a new network selection procedure using access networks consent. The proposed mechanism supports WLAN, WIMAX and 3G networks. Using mobility prediction model coupled with GIS information system the access networks at future location of mobile terminal. Using pre handover mechanisms with EAP HO NS and AAA extensions proposed in this paper the home access networks negotiate with visiting access networks and networks entities to allocate and reserve resources for accommodating mobile terminals enabling the solution proposed is efficient. Using these mechanisms the mobile terminal mobility can be handled efficiently in any access networks. The proposed solution addresses all the issues that are raised by network selection procedures. As a part of our future work we are coupling this mechanism with security, mobility and handover management procedures to control and provide seamless handover during roaming.
