Mobile IPv4 is a standard mobility protocol that enables an IPv4device to move among networks while maintaining its IP address. Themobile device has the Mobile IPv4 client function to signal itslocation to the routing anchor, known as the Home Agent. However,there are many IPv4 devices without such capability due to variousreasons. This document describes Proxy Mobile IPv4 (PMIPv4), a schemebased on having the Mobile IPv4 client function in a network entity toprovide mobility support for an unaltered and mobility-unaware IPv4device. This document also describes a particular application ofPMIPv4 as specified in the WiMAX Forum and another application that isto be adopted in 3GPP2. This document is not an Internet StandardsTrack specification; it is published for informational purposes.
