This paper aims to explore the link between mobility, authentication, identity, entitlement and trust. Research into these generic enablers is consistent with the existing trend for convergence in its widest context, building from the converged connectivity aspects found in the next generation network common capability strategy. Awareness of when (and how) to successfully manipulate these links is not simply the cornerstone for becoming a successful ICT service provider but, more significantly, the ultimate differentiation for any service provision.
