Working with PDN-Gateways (P-GW)
A PDN Gateway (P-GW) is the node that terminates the SGi interface towards the PDN. If a user
equipment (UE) is accessing multiple PDNs, there may be more than one P-GW for that UE. The P-GW
provides connectivity to the UE to external packet data networks by being the point of exit and entry of
traffic for the UE. A UE may have simultaneous connectivity with more than one P-GW for accessing
multiple PDNs.
The P-GW facilitates policy enforcement, packet filtering for each user, charging support, lawful
interception, and packet screening. The features of P-GW include:
• Integration of multiple core network functions in a single node
• Multiple instances of P-GW can enable call localization and local breakout
• High performance across all parameters like, signaling, throughput, density, and latency
• Integrated in-line services
• Support for enhanced content charging, content filtering with blacklisting, dynamic network-based
traffic optimization, application detection and optimization, stateful firewall, NAT translation, and
lawful intercept
• High-availability helps to ensure subscriber satisfaction
The following topics explain how to work with P-GW in Prime Network Vision:
• Viewing P-GW Properties, page 25-44
• P-GW Commands, page 25-45
Viewing P-GW Properties
Prime Network Vision displays the P-GWs in a P-GW container under the Mobile node in the logical
inventory. The icon used for representing P-GW in the logical inventory is explained in Logical
Inventory Icons, page A-7.
To view P-GW 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 > P-GW Container.
Prime Network Vision displays the list of P-GW services configured under the container. You can view
the individual P-GW service details from the table on the right pane or by choosing Logical
Inventory >Context > Mobile > P-GW Container > P-GW.
Table 25-25 describes the details available for each P-GW.
