The SSG Proxy for CDMA2000 feature allows you to extend the functionality of the existing SSG 
RADIUS proxy so that it may be used in CDMA2000 networks.

Code Division Multiple Access (CDMA) is a digital spread-spectrum modulation technique used mainly 
with personal communications devices such as mobile phones. CDMA digitizes the conversation and 
tags it with a special frequency code. The data is then scattered across the frequency band in a 
pseudorandom pattern. The receiving device is instructed to decipher only the data corresponding to a 
particular code to reconstruct the signal.

When used in a CDMA2000 network, the Service Selection Gateway (SSG) provides RADIUS proxy 
services to the Packet Data Serving Node (PDSN) and the Home Agent (HA) for both Simple IP and 
Mobile IP authentication. SSG also provides service selection management and policy-based traffic 
direction for subscribers.

SSG Proxy for CDMA2000, used with Cisco Subscriber Edge Services Manager (SESM), provides users 
with on-demand services and service providers with service management and subscriber management.

SSG Proxy for CDMA2000 supports time- and volume-based usage accounting for Simple IP and 
Mobile IP sessions. Prepaid and postpaid services are supported. Host accounting records can be sent to 
multiple network elements, including Content Service Gateways (CSGs), Content Optimization Engines 
(COEs), and Wireless Application Protocol (WAP) gateways.
