This document provides user level descriptions and access network call flows and messages designed to assist in the understanding of BCMCS operation. It defines the messages, procedures and timers for the interfaces that coincide with the reference points: "A", "A_quater", and "A_quinter", as defined in the Network Reference Model. Refer to [I-1].

This document may be used in conjunction with any of the following standards:

•IOS (refer to [11] ~ [17])

•HRPD IOS with SC/MM in the AN (refer to [19])

•HRPD IOS with SC/MM in the PCF (refer to [20])

This document is a superset of the information needed to support BCMCS on three types of cdma2000 radio access networks: 1x, HRPD with SC/MM in the AN, and HRPD with SC/MM in the PCF. As such, not all information in this document is applicable to a given implementation. For example, A14 messaging does not apply to cdma2000 1x networks or HRPD networks with SC/MM in the AN.

Purpose

The purpose of this document is to provide IOS feature description (stage 1), IOS feature call flows (stage 2) and IOS message definitions (stage 3) for support of BCMCS in cdma2000^®1 networks. This document covers access network support for BCMCS over cdma2000 1x and High Rate Packet Data (HRPD) air interfaces.
