27-28 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks GPRS/UMTS Networks GTPP Commands The following GTPP-related commands can be launched from the inventory by right-clicking a GTPP and choosing Commands > Configuration or Commands > Show. Your permissions determine whether you can run these commands (see Permissions Required to Perform Tasks Using the Prime Network Clients). To find out if a device supports these commands, see the Cisco Prime Network 4.3.2 Supported Cisco VNEs. Table 27-15 GTPP Commands Command Navigation Description Create CGFRight-click the GTPP group> Commands> ConfigurationThe Charging Gateway Function (CGF) listens to GTP messages sent from the GSNs on TCP/UDP port 3386. The core network sends charging information to the CGF, typically including PDP context activation times and the quantity of data which the end user has transferred. However, this communication which occurs within one network is less standardized and may, depending on the vendor and configuration options, use proprietary encoding or even an entirely proprietary system. Use this command to create a new CGF. Create Storage ServerThe GTPP Storage Server (GSS) provides an external management solution for the bulk storage of Charging Data Records (CDRs) coming from a GPRS Support Node (GSN) in a GPRS/UMTS network. Use this command to create a storage server. Modify Storage ServerRight-click the GTPP group> Storage ServerUse this command to modify storage server configuration details. Delete Storage ServerUse this command to delete a storage server.

Your permissions determine whether you can run these commands (see Permissions Required to Perform Tasks Using the Prime Network Clients). To find out if a device supports these commands, see the Cisco Prime Network 4.3.2 Supported Cisco VNEs. Monitoring the Serving GPRS Support Node (SGSN) The Serving GPRS Support Node (SGSN) is a very important component of the GPRS network. It is responsible for handling the delivery of data from and to the mobile nodes within its geographical service area, such as packet routing and transfer, mobility management, and authentication of users. Along with the Radio Access Network (RAN) and Gateway GPRS Support Node (GGSN), the SGSN: Communicates with the Home Location Registers (HLR) via a Gr interface and with the mobile Visitor Location Registers (VLR) via a Gs interface to register a subscriber’s equipment or authenticate, retrieve and update the subscriber’s profile information. Supports Gd interface to provide short message service (SMS) and other text-based network services to subscribers. Activates and manages IPv4, IPv6 or point-to-point (PPP) type packet data protocol (PDP) contexts for a subscriber session. Manages the data plane between the RAN and GGSN providing high speed data transfer with configurable GEA0-3 ciphering. Provides mobility management, location management, and session management for the duration of call to ensure smooth handover. Provides different types of charging data records (CDR) to attached accounting or billing storage mechanisms Provides Communications Assistance for Law Enforcement Act (CALEA) support for lawful intercepts. Viewing the SGSN Configuration Details To view the SGSN configuration details: Step 1Right-click the required device in the Vision client and choose Inventory. Step 2In the Logical Inventory window, choose Logical Inventory > Context> Mobile > SGSN.
