The document outlines various scenarios for establishing and releasing HRPD sessions between an access terminal (AT) and air interface (AN) on a CDMA network. It describes successful and unsuccessful authentication procedures when the AT originates a session, as well as call reactivation from dormancy initiated by the network or AT. It also covers connection and session release that can be initiated by the AT, AN, or PDSN.
