Abstract:
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 a neighbor cell which the user equipment enters is a LTE macrocell or a LTE femtocell based on the measurement report, wherein the LTE femtocell is overlapped with a neighbor WCDMA macrocell; and performing handover of the user equipment to a base station of the neighbor WCDMA macrocell when (i) the neighbor cell is determined as the LTE femtocell and (ii) a base station of the LTE femtocell uses a same frequency as the LTE macrocell base station corresponding to a current serving base station.
