Working with the Gateway GPRS Support Node(GGSN)

The GGSN works in conjunction with SGSNs within the network to perform the following functions:
• Establish and maintain subscriber Internet Protocol (IP) or Point-to-Point Protocol (PPP) type
Packet Data Protocol (PDP) contexts originated by either the mobile or the network.
• Provide charging detail records (CDRs) to the charging gateway ((CG), also known as the Charging
Gateway Function (CGF)).
• Route data traffic between the subscriber’s Mobile Station (MS) and a PDN such as the Internet or
an intranet.
