SCM in a CDMA2000 Data Network Deployment
Integrated CSCF / A-BG / HA
The SCM is designed to function within a CDMA2000 PDSN network. By combining the SCM with a carrier-class
Home Agent, a number of advantages emerge such as increased performance, distributed architecture, and high
availability. As shown in the figure below, the SCM supports a number of interfaces used to communicate with other
components in an IMS environment and supports the interface used to bridge the CDMA network.
