Handover method and apparatus in a wireless communication system including femto cells

摘要

A handover method and apparatus for facilitating a handover of a user equipment to a femto cell in a wireless communication system supporting both the femto and macro cells. When a handover condition is detected, the user equipment acquires identity information of a target femto cell base station from system information transmitted by the target femto cell base station, decides whether to handover to the target femto cell base station, based on the identity information; and transmits a measurement report message including the identity information to a serving base station of the user equipment, when the handover is to be made.

1. A handover method of a User Equipment (UE) in a wireless communication system including a Home eNodeB (HeNB), the method comprising:
receiving system information including a Cell IDentification (ID), a Tracking Area ID (TAI) and a CSG (Closed Subscriber Group) ID, from a target HeNB; generating and sending a measurement report, the measurement report including the Cell ID, Tracking Area ID (TAI) and CSG (Closed Subscriber Group) ID of the target HeNB; receiving a Handover Command message from a source eNB; and performing a handover to the target HeNB, wherein the CSG ID included in the measurement report is compared, by the target HeNB, with a CSG ID broadcast in the target HeNB to verify whether the CSG ID in the measurement report matches a CSG ID broadcast in the target HeNB.
