                 WiMAX Forum / 3GPP2 Proxy Mobile IPv4

Abstract

   Mobile IPv4 is a standard mobility protocol that enables an IPv4
   device to move among networks while maintaining its IP address.  The
   mobile device has the Mobile IPv4 client function to signal its
   location to the routing anchor, known as the Home Agent.  However,
   there are many IPv4 devices without such capability due to various
   reasons.  This document describes Proxy Mobile IPv4 (PMIPv4), a
   scheme based on having the Mobile IPv4 client function in a network
   entity to provide mobility support for an unaltered and mobility-
   unaware IPv4 device.  This document also describes a particular
   application of PMIPv4 as specified in the WiMAX Forum and another
   application that is to be adopted in 3GPP2.
