Abstract

A communication system transfers communication from one communication domain (analog) (105) to another, unlike communication domain (digital). The communication system uses a transition cell having both analog and digital coverage areas overlapping in a 1:1 RF footprint. The transition cell is partitioned into sectors, each sector marked with either an analog or digital domain indication. When a subscriber unit (100) enters the transition cell from one domain, an inter-cell handoff into the transition cell within the same domain is performed. When the subscriber unit enters a sector having an opposite domain indication, an intra-cell handoff is performed. If the subscriber unit (100) then moves out of the transition cell, an inter-cell handoff into the new domain is performed.
