2G – General Packet Radio Service (GPRS) Support Node

iCore® 2G – General Packet Radio Service (GPRS) Support Node

The iCore 2G is a compact, carrier-grade General Packet Radio Service (GPRS) support node facilitating GPRS and EDGE packet data access. The platform can be deployed as a Serving GPRS Support Node (SGSN), Gateway GPRS Support Node (GGSN) or both. Designed to cost-effectively introduce data services to a 2G network, this node fits into the iCore 2G-3G-4G product portfolio as shown on the left. This architecture enables operators to evolve to future generations through software plug-ins, increasing flexibility and reducing cost of upgrades.

As with all Tecore products, the GSN is fully compliant with the applicable 3GPP standards, is available on a standalone basis on a range of carrier-grade hardware platforms, and can also be integrated as a blade in a complete iCore network system. The iCore 2G GSN has been deployed in standalone and roaming networks connecting with infrastructure and devices from the industry’s leading vendors.

Target markets include:

  • Rural network operators introducing data services or needing to add packet data support to maintain roaming agreements
  • Remote islands, villages, and oil fields
  • Operators in developing markets offering data services
  • Rapid deployment systems for emergency communications restoration
  • Transportable networks including vehicle-mounted, airborne and maritime systems
  • Government and military data applications
  • Enterprise and university campuses

Operating System

  • Linux-based processing

SGSN Interface

  • Base Station Subsystem (Gb)
  • HLR (Gr), EIR (Gf), SMS-IWMSC (Gd),
  • MSC/VLR (Gs)
  • Charging Gateway (Ga) – supports GTP over UDP/IP to connect with an external
  • Charging Gateway
  • Other GSN (Gn)

GGSN Interface

  • External IP networks (Gi) and other GSN (Gn)
  • HLR (Gc)
  • Charging Gateway (Ga)

Configuration and Manageability

  • Configuration Management – includes system parameter specifications, the addresses of network components, and the configuration parameters of protocol stacks
  • Fault Monitoring – fault monitoring is achieved by generating alarms
  • Status Monitoring – periodic collection and analysis of data related to a GSN node. The GSN allows the periodic collection of statistics and recording thereof in a log file for analysis.
  • SNMP-Based Management

Features and Benefits

  • Streamlined architecture that is scalable and combines features of both SGSN and GGSN in the same physical node
  • Interoperable with leading vendors equipment and devices
  • Built on Linux OS
