Generic Access Network Dual-Mode Services: Architectural and Security Implications

Tags:
access technologies

Overview The introduction of dual-mode handsets, which support both Global System for Mobile Communications (GSM) and Wi-Fi, provides mobile operators with a new opportunity to accelerate their customers' adoption of mobile services. By extending GSM voice and data services over the wireless broadband connection in subscribers' homes, mobile operators can take advantage of similar favorable economics enjoyed by VoIP-over-broadband providers. The adoption of this IP-based infrastructure, however, brings with it both the inherent security vulnerabilities of IP and the intelligent, network-based solutions to resolve these vulnerabilities. This paper describes the Generic Access Network (GAN) standards, security implications, and the Cisco GAN dual-mode solution: the Cisco GAN Enhanced Security Gateway.
