On October 11, 2006, DOJ closed its investigation into the AT&T/BellSouth merger withoutfurther action. On December 29, 2006, FCC approved it. The competitive framework formedduring the preceding SBC/AT&T and Verizon/MCI merger proceedings was strengthened withthese approvals. However, the scope of the merger remedies including those ensured in themerger commitments is not so broad. They mainly focus on existing communications networksbased on PSTN, including no small parts of the Internet. Problems raised by the NextGeneration Network (NGN) and Fixed Mobile Convergence (FMC) are yet to be solved.Government authorities should make the comprehensive framework based on the layers modelfor the future.
