This document provides an interoperability specification for a RAN that supports HRPD. The RAN architecture in this document logically locates the Session Control and Mobility Management (SC/MM) function in the Access Network (AN). This document contains message procedures and formats necessary to obtain this interoperability.

Purpose

The purpose of this document is to provide a standard and call flows for the IOS HRPD interfaces within the Radio Access Network (RAN).
