Cisco GGSN Gateway GPRS Support Node:
Connectivity for the UMTS/HSPA Packet Core
Connectivity for the UMTS/HSPA Packet Core
Mobile subscribers want access to email, the Internet, mobile TV, video on demand, instant messaging,
and other multimedia services through a mobile broadband connection.
This requires mobile operators to deploy a robust, scalable packet core network capable of processing massive
amounts of throughput with exceptional reliability and availability.
Cisco GGSN Gateway GPRS Support Node has become the choice for many of the world’s most innovative 3rd
Generation Partnership Project (3GPP) network operators deploying GSM, Universal Mobile Telecommunications
Service (UMTS), and High Speed Packet Access (HSPA) networks. Supported on the Cisco
®
ASR 5000, the GGSN
delivers exceptional throughput, call transaction rates, and packet processing, along with significant memory
resources. With its subscriber and network intelligence, reliability, and availability, the GGSN allows mobile
operators to focus on building high-margin revenue streams without worrying about the packet core.
Cisco’s GGSN acts as the gateway between the packet core and the external packet- or IP-based network, such as
the Internet. Located at the heart of the mobile packet core network, the GGSN plays a critical role in policy
enforcement, network protection, security, quality of service (QoS) enforcement, and interaction with charging and
billing systems. It can also be combined with Cisco SGSN Serving GPRS Support Node on a single platform to
maximize efficiency and flexibility, reduce latency, and simplify network architecture.
Network Migration
Cisco’s GGSN supports major standards for deployment in GPRS/EDGE/UMTS/WCDMA/HSPA networks. With
simple software upgrades, Cisco’s GGSN can support present and future 3GPP technologies to protect your
investments as your network evolves to support Long Term Evolution (LTE)/Evolved Packet Core (EPC) and multi-
access requirements (Wi-Fi, femtocell, etc.).
In-line Services
The Cisco ASR 5000 platform features the unique capability to deploy services “in-line,” meaning the services are
integrated into the bearer traffic plane at the edge of the packet core network. This capability provides in-depth
session awareness that allows network management on a per-subscriber basis and deployment of content-aware
applications. Tasks are performed without introducing latency, session interruption, or other kinds of signal
degradation.
Cisco’s In-line Services use deep packet inspection and intelligent traffic steering to offer the following:
●
Enhanced traffic monitoring, metering, and charging (interaction with standard RADIUS and GPRS Tunneling
Protocol [GTP] charging and billing systems)
●
Application detection and optimization for peer-to-peer (P2P) detection and control
●
Network-based traffic optimization to achieve QoS based on volume, usage, time-of-day, and traffic type
●
Stateful firewall
●
Content filtering for parental control, black/white listing
