HANDOVER IN LONG TERM EVOLUTION NETWORK
First Claim
1. A method of handover in a long term evolution (LTE) communication network including LTE macrocells and LTE femtocells and overlapping with at least one wideband code division multiple access (WCDMA) macrocell, the method in the LTE macrocell base station, comprising:
- receiving a measurement report from user equipment while providing a communication service to the user equipment located within a service area of the LTE macrocell base station;
determining whether the neighbor cell is a LTE macrocell or a LTE femtocell based on the measurement report; and
performing handover of the user equipment to a neighbor WCDMA macrocell base station when the neighbor cell is determined as the LTE femtocell.

Abstract
Described embodiments provide for handover in a long term evolution (LTE) communication network. A LTE macrocell base station may receive a measurement report from user equipment while providing a communication service to the user equipment located within a service area of the LTE macrocell base station, and determine whether or not the neighbor cell is a LTE macrocell or a LTE femtocell based on the measurement report. The LTE macrocell base station may initiate hand-over of the user equipment to a neighbor WCDMA macrocell base station when the neighbor cell is determined as the LTE femtocell.
