GPRS/UMTS Networks
In addition, to providing basic GGSN functionality as described above, the system can be configured to
support Mobile IP and/or Proxy Mobile IP data applications in order to provide mobility for subscriber
IP PDP contexts. When supporting these services, the system can be configured to function as a GGSN
and Foreign Agent (FA), a stand-alone Home Agent (HA), or a GGSN, FA, and HA simultaneously
within the carrier's network.
The following topics explain how to work with GGSN in Prime Network Vision:
• Viewing GGSN Properties, page 25-7
• Viewing Additional Characteristics of a GGSN, page 25-8
• GGSN Commands, page 25-10
Viewing GGSN Properties
Prime Network Vision displays the GGSNs in a GGSN container under the Mobile node in the logical
inventory. The icon used for representing GGSNs in the logical inventory is explained in Logical
Inventory Icons, page A-7.
To view GGSN properties:
Step 1 Right-click the required device in Prime Network Vision and choose Inventory.
Step 2 In the logical inventory window, choose Logical Inventory > Context > Mobile > GGSN Container.
Prime Network Vision displays the list of GGSNs configured under the container. You can view the
individual GGSN details from the table on the right pane or by choosing Logical
Inventory > Context > Mobile > GGSN Container > GGSN.
Table 25-3 describes the details available for each GGSN.
