    Converged IP/MPLS Backbone Networks for 2G and 3G Voice Services Integration

    White Paper Converged IP/MPLS Backbone Networks for 2G and 3G Voice Services Integration With Release 4 of the third-generation (3G) architectural standards for mobile networks, mobile operators can now reduce costs, enhance revenues, and decrease time to market for new voice-over-IP (VoIP) and traditional voice services. When mobile operators deploy a new split architecture to support voice, and consolidate 2G and 3G voice over an IP/Multiprotocol Label Switching (IP/MPLS) backbone network, existing 2G and newer 3G voice traffic can greatly benefit from simplified operations, multigigabit speeds, transport efficiency, quality of service (QoS), traffic engineering, and all of the features required of carrier-class networks. This paper describes how IP/MPLS technologies support the emerging VoIP infrastructure in mobile networks to facilitate the convergence of 2G and 3G mobile voice services, including the evolution of the VoIP network from the split architecture in 3G Release 4 to the introduction of the IP-enabled media gateway, and how available technologies from Cisco Systems® can help operators effectively manage converged IP/MPLS mobile networks. Summary Most mobile operators are now firmly focused on consolidating transmission and management of a broad range of mobile services deployed on disparate networks to reduce their capital expenses (CapEx) and operating expenses (OpEx), increase business agility, and more easily deploy new 3G IP-based services. Cisco® has helped both wireless and wireline carriers accomplish such consolidation while greatly enhancing performance and network features by converging disparate networks into one common IP/MPLS core to support both existing and future services. The Cisco IP Next-Generation Network (IP NGN) architecture for mobile operators is a roadmap to realize the vision of next-generation mobile services – the delivery of data, voice, and video anywhere and anytime across virtually any access technology.

Without this basic function, features such as hand-over between cells would not work. Since mobile devices are typically associated with a single person, this provides a potential mechanism for user location surveillance. Network operators are bound by strict privacy legislation. However, spying by certain agencies, hackers and even advertisers without the users’ or operators’ knowledge has become a serious issue. In this article, we introduce and explain all known recent attacks on mobile networks that compromised user privacy. We focus on attacks using the Signalling System 7 (SS7) protocol as the interconnection interface between operators mainly in GSM networks.
