    Abstract: Handoff from a Code-Division, Multiple Access (CDMA) protocol to an Advanced Mobile Phone Service (AMPS) protocol occurs by comparing a remote unit's (405) phase shift measurement to a threshold (503) and determining a reference CDMA base station (401) from an active set of CDMA base stations (515). Next, corrected phase shifts are calculated for each CDMA base station in the active set (521) and the remote unit (405) is handed off to an AMPS base station (109) underlying the CDMA coverage area (126) having the smallest corrected phase shift (525).

    Abstract: One or more characteristics of a PTT bearer message exchange between an originating mobile station (102) and a target mobile station (120) is determined. An expiration period of the inactivity timer (108) is programmed based upon the one or more characteristics of the PTT bearer message exchange.
