Features and Technologies
Cisco PDSN is a hardware and IOS software feature that enables a Cisco 7500 series router to function as a gateway between the wireless Radio Access Network (RAN) and the Internet. With Cisco PDSN enabled on a router, a stationary or roaming mobile user can access the Internet, a corporate network intranet, or Wireless Application Protocol (WAP) services. Cisco PDSN supports both Simple IP operation and Mobile IP operation.
Note :Cisco PDSN supports both Simple IP operation and Mobile IP operation, which are referred to as service types. The service type available to a user is determined by the mobile station and by the type of service offered by the service provider. In the context of PDSN, a mobile station is the end user in both Simple IP and Mobile IP operation.
The CDMA2000 network architecture is defined in TIA/EIA/IS-835 Wireless IP Network Standard (also known as 3GPP2 TSG-P and as TR45.6). A typical CDMA2000 network includes terminal equipment, mobile termination, base transceiver stations (BTS), base station controllers (BSC), PDSNs, and other CDMA network and data network entities. In a CDMA cellular network, PDSN is the interface between a BSC and a network router.
Each standard is aligned with IP.
Second generation (2G) data investment is aligned with third
generation (3G) investment.
Enables seamless delivery of IP-based services.
Supports existing air interfaces.
Consistent with wireline network evolution.
Supports hybrid, multi-standard networks.
Enables Simple IP mobile stations to benefit from mobility.
Improves the customer experience by minimizing disruption to
applications when handoff occurs.
Selects best PDSN based on workload and prior sessions.
Enables optimal performance.
Scales without disruption service.
Cisco hardware platforms are proven in some of the largest networks
in the world.
PDSN runs with the standard Cisco IOS feature set, which includes
rich IP, security, QoS, mobile IP, and voice-data integration capability.
