Monitoring the Serving GPRS Support Node (SGSN)

The Serving GPRS Support Node (SGSN) is a very important co mponent of the GPRS net work. It is

responsible for handling the delivery of data from and to the mobile nodes within its geographical servi ce

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 SG SN:

• 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 ser vices

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 (CAL EA) su ppor t f or lawful

intercepts.
