Abstract:
1. A method of supporting handoff when a mobile station is in idle mode, the method comprising: receiving and storing configuration information of neighboring base stations; detecting a pilot signal strength of a target base station that is greater than the target signal strength of a source base station, while checking a strength of pilot channels of the neighboring base stations; checking whether configuration information of the target base station exists among the stored configuration information of the neighboring base stations; and determining how to perform idle handoff based upon the checking, wherein the mobile station performs normal handoff procedures if the mobile station has monitored a paging channel (PCH) before performing idle handoff, has selected a neighbor base station for idle handoff which supports primary broadcast control channel (P-BCCH) and has received parameters for the P-BCCH of the neighbor base station via a broadcast/multicast service parameters message (BSPM).
