Method for controlling heterogeneous network handover and apparatus therefor

Abstract

Provided are apparatus and methods for controlling a handover of a user equipment between base stations each belonging to a network different from the other. The method includes: i) determining whether the user equipment should be handed over to a target base station belonging to a heterogeneous network based on measurement information received from the user equipment, ii) transmitting a handover required message containing identification information of the target base station to a core network entity linked to the source base station, when it is determined that the user equipment should be handed over, iii) receiving a handover command message containing evolved packet system (EPS) bearer setup list information of the target base station from the core network entity, and iv) transmitting the handover command message to the user equipment.
