This Chapter addresses the international response of policy-makers and regulators to convergence and its effects on their legal and regulatory frameworks. First, it analyses the different regulatory approaches most commonly used to address convergence (i.e., legislative, regulatory and self-regulation approaches) and describes the advantages and disadvantages of each approach. Second, it outlines the impact that convergence is having on different regulatory processes, namely licensing, spectrum, interconnection, universal service, and numbering. Finally, it analyses and describes the type of legislation and regulatory processes that should be implemented by countries to facilitate a converged environment.
