Abstract
To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention provides soft handoff to mobile stations (MSs) () in a dispatch call by sharing soft handoff information with all the MSs in the call at a base site (). When a first MS (e.g.,) needs to soft handoff, the identity of a soft handoff channel () at an adjacent base site () is shared with all the MSs. Thus, subsequent MSs (e.g.) that need to soft handoff to that adjacent base site may do so without requesting a soft handoff.
