Cisco Gateway GPRS Support Node (GGSN) The General Packet Radio Service (GPRS) provides packet radio access for mobile Global System for Mobile Communications (GSM). In addition to providing new data services for today's mobile user, GPRS is important as a migration step toward third-generation (3G) networks. GPRS allows network operators to implement IP-based core architecture for data applications, which will continue to be used and expanded for 3G Universal Mobile Telecommunications Service (UMTS) for integrated voice and data applications. The Cisco GPRS solution enables mobile wireless operators to provide advanced mobile data services to network subscribers in all market segments. The Cisco Gateway GPRS Support Node (GGSN) offers standard 3rd Generation Partnership Project (3GPP) GPRS functionalities in addition to the Cisco value-added features in a single Cisco router platform. The Cisco IOS Software within the Cisco GGSN provides a sophisticated suite of networking capabilities that reside at the heart of internetworking devices. Cisco GGSN and data network components interoperate with external packet-data networks, and the Cisco GGSN is connected to the Cisco Serving GPRS Support Node (SGSN) through an IP-based GPRS backbone network. The Cisco GGSN provides IP connectivity to mobile users, to public services (Internet, Wireless Application Protocol [WAP], and multimedia messaging [MMS]), and to corporate virtual private networks (VPNs).
By implementing Cisco GPRS products and related solutions, mobile operators can optimize their networks to deploy high-quality mobile voice and data services. They can also benefit from new operating efficiencies, peer-to-peer IP-based architecture for scalability, and IP standard interfaces to billing (prepaid and postpaid) and customer support. The Cisco GGSN, combined with its routing capability, offers the same level of quality, reliability, and scalability that has made Cisco a leader in the Internet and data networking industry. Moreover, the Cisco GGSN 3.0 on a Cisco 7206 VXR with the Cisco NPE 400 Network Processing Engine is supported by CiscoWorks for Mobile Wireless network management, which is equipped with fault management, access point name (APN) management, and configuration management for the Cisco GGSN.
