Universal Mobility with Global Identity (UMGI) Architecture

The resultant escalation of cyber attacks and the emerging needs of operators to increase their coverage with a blended service offering, that enhances user mobility, have raised a need for an architecture that can find global digital identities and link them back to users´ activities in the mobility universe. In this paper, our focus is to provide an architecture that associates mobile users´ credentials as IP,hostname, and network equipment identifiers (ex. network cards or mobile sets) with their (U)SIM (Universal subscriber identity module) cards to create a global identity.Then the architecture makes use of this global identity to extend the user mobility to universal mobility. The architecture proposes the Universal mobility concept by adopting a new mobile IP (MIP) architecture to enables users to maintain their connection to their corporate or to an internet service when moving between different access networks without impacting their existing sessions and with minimum handover time. The main advantages of the new mobile IP concept is; its independence of the access media or the user´s equipment. Being independent of the user´s equipment is a goal as loading equipments with complex application will decrease its performance and increase the power consumption thus destroying the concept of mobility.The second advantage is enhancing the new MIP concept with a strong security mechanism that protects against identity spoofing. This mechanism adopts a secure hierarchal method for message passing, authentication and addresses the security limitation of standard internet protocols like DHCP, ARP, and DNS ...etc.
