CDMA2000 Wireless Data Services
▄ Cisco ASR 5000 Series Product Overview
Product Description
The system provides wireless carriers with a flexible solution that can support both Simple IP and Mobile IP
applications (independently or simultaneously) within a single scalable platform.
When supporting Simple IP data applications, the system is configured to perform the role of a Packet Data Serving
Node (PDSN) within the carrier's 3G CDMA2000 data network. The PDSN terminates the mobile subscriber‘s Point-to-
Point Protocol (PPP) session and then routes data to and from the Packet Data Network (PDN) on behalf of the
subscriber. The PDN could consist of Wireless Application Protocol (WAP) servers or it could be the Internet.
When supporting Mobile IP and/or Proxy Mobile IP data applications, the system can be configured to perform the role
of the PDSN/Foreign Agent (FA) and/or the Home Agent (HA) within the carrier's 3G CDMA2000 data network. When
functioning as an HA, the system can either be located within the carrier‘s 3G network or in an external enterprise or
ISP network. Regardless, the PDSN/FA terminates the mobile subscriber‘s PPP session, and then routes data to and
from the appropriate HA on behalf of the subscriber.
