Handoffs within a wireless communication system (20) include using a common cell definition code for each of a plurality of microcell BTSs (30, 40, 50) to facilitate handoffs between a macrocell (26) and any one of the microcells. In a disclosed example, a common cell definition code such as a PN offset or a scrambling code is used to trigger a handoff from the macrocell (26) to any one of the microcell BTSs (30, 40, 50). A mobile station locate feature identifies which of the BTSs is involved in the handoff. Another common cell definition code is used in one example to trigger all handoffs from any one of the microcells (30, 40, 50) to the macrocell (26). Soft handoff and hard handoff examples are disclosed. ® KIPO & WIPO 2009 |
