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.,

                  The Service Option is a parameter 
                  that specifies the air interface 
                  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.

  PCF             Physical interface connecting the 
                  RAN to a PDSN
