Method and apparatus for mobile-initiated, CDMA-dispatch soft handoff

摘要

To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention enables mobile-initiated soft handoff for dispatch calls. A mobile station (120) in a dispatch call establishes an individual inbound link (137) with the serving base site (111). When the mobile station determines that a handoff with an adjacent site (112) is needed, the mobile station uses its individual inbound link to request a soft handoff with the adjacent base site. After notifying the adjacent base site, the serving base site then transmits the handoff information to the mobile station to enable the mobile station to begin a soft handoff with the adjacent site.
