TIA TIA-878-A

This document provides an interoperability specification for a Radio Access Network (RAN) that supports HRPD. This document contains message procedures and formats necessary to obtain this interoperability.

• AT originates a HRPD session (including access authentication)

• HRPD data delivery (both AT terminated and AT originated)

• Re-authentication of an AT

• HRPD connection release

• HRPD session release

• Dormant handoff of HRPD AT between ANs served by the same PDSN

• Dormant (voice or packet) cdma2000 handoff to/from HRPD, served by the same PDSN

• MS/AT terminated voice call during active HRPD data session

• cdma2000 to HRPD active packet data session handoff

• Loss of the airlink during an active HRPD session

• Status Management supported by feature invocation
