Description: This MIB is to support the Closed RP feature of CDMA
       PDSN that supports wireless data communication 
       through 3G CDMA radio access technology.  PDSN acts
       as a foreign agent that establishes, maintains and
       terminates the link layer to a mobile station.

       The high level architecture of a third generation 
       CDMA2000 network is shown below:

       The CDMA PDSN CRP MIB provides operational information
       for a Closed RP implementation.  The following areas 
       are managed:

           1) Global PDSN information.  This area contains 
              generic information such as the number of 
              incoming call requests, incoming call replies 
              etc.,

                         between MS and RN for packet 
                         data service.
                       

         Mobile Station/ A host or router that changes its 
         Mobile Node     point of attachment from one 
                         network or subnetwork to another.
                         A mobile node may change its 
                         location without changing its
                         IP address.

         Mobile IP       Protocol enhancements that allow 
                         transparent routing of IP datagrams
                         to mobile nodes.  Refer to RFC 2002
                         for more details.

         Mobile Client   A component which can interact with
                         MoIP entities such as Foreign Agent
                         and Home Agent.

         Home Agent      A router on a mobile node's home 
                         network which tunnels datagrams for 
                         delivery to the mobile node when it
                         is away from home, and maintains 
                         current location information for the
                         mobile node.  Refer to RFC 2002 for 
                         more details.

         Foreign Agent   A router on a mobile node's visited
                         network which provides routing 
                         services to the mobile node while 
                         registered.  The foreign agent 
                         delivers datagrams to the mobile
                         node that were tunneled by the 
                         mobile node's home agent.  For 
                         datagrams sent by a mobile node, the
                         foreign agent may serve as a default
                         router for registered mobile nodes.
                         Refer to RFC 2002 for more details.

         Proxy           Mechanism used by PDSN to provide 
         Mobile Ip       MoIP services to a MS which does
                         not implement a mobile client.  PDSN
                         will be the proxy MC for the MS.

         Simple IP       IP routing used by a MS when MoIP
                         services are not needed.

         PDSN flow       A conversation between one user 
                         (identified by an IP address) and 
                         a HA using a PDSN session.

         PDSN session    A PPP connection between a MS and 
                         the PDSN.  One session may contain 
                         one or multiple PDSN flows.

                         RAN to a PDSN
