Direct Tunnel and FastPath Support
The SGSN makes use of the Direct Tunnel architecture, which enables the SGSN to establish a direct subscriber
plane tunnel between the radio access network (RAN) and the GGSN. In addition, the Cisco ASR 5000 also supports
FastPath, which frees up the SGSN to perform other high-touch services and signaling procedures. With FastPath,
no change is required to your architecture because the SGSN discerns no difference between home and roaming
users, eliminating the need to perform new procedures.
Location Management
The SGSN supports outstanding scalability of standards-based routing area updates (RAUs) for location
management, including periodic RAUs, intra-SGSN RAUs, and inter-SGSN RAUs. Further, the SGSN’s high capacity
and flexible functionality provide a great opportunity to convert high-impact inter-SGSN RAUs to lower-impact intra-
SGSN RAUs.
Session Management
Cisco’s SGSN performs comprehensive session management, including context activation, modification,
deactivation, and preservation. It also provides support for IPv4, IPv6, and PPP PDP context types. In addition, the
SGSN’s intelligent PDP context preservation feature facilitates efficient radio resource utilization.
Charging
The SGSN supplies standards-based SGSN call detail records (S-CDRs) and mobility call detail records (M-CDRs).
Further, the SGSN implements the standardized Ga interface for the exchange of charging data with one or more
configured Charging Gateway Functions (CGFs).
Conclusion
The Cisco SGSN provides comprehensive, high-capacity, and standards-compliant GSM/GPRS, EDGE, UMTS, and
HSPA network access. With the SGSN, you can minimize capital and operational costs, ease deployment of
revenue-generating services, and improve the reliability of your network to boost your competitive edge.
