Before executing any commands, you can preview them and view the results. If desired, you can also
schedule the commands. To find out if a device supports these commands, see the Cisco Prime Network
4.0 Supported Cisco VNEs.
Note You might be prompted to enter your device access credentials while executing a command. Once you
have entered them, these credentials will be used for every subsequent execution of a command in the
same GUI client session. If you want to change the credentials, click Edit Credentials. The Edit
Credentials button will not be available for SNMP commands or if the command is scheduled for a later
time.
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.
