Network Deployments and Interfaces 
 
The GSS, in either a stand-alone or a cluster configuration, partners with a GSN (either an SGSN or a GGSN) in a 
GPRS/UMTS network to support a secure accounting solution. Optionally, other elements are included as needed such 
as a billing/mediation system, a RADIUS AAA server, a fiber channel common storage server, and/or a Charging 
Gateway Function (CGF). 
 
Deploying the GSS 
The following figure shows two typical deployments of the GSS in a GPRS/UMTS network.
