Title: METHOD FOR CONTROLLING HETEROGENEOUS NETWORK HANDOVER AND APPARATUS THEREFOR
Abstract:
The present disclosure relates to a technique for controlling handover of a terminal between base stations using different networks. One embodiment provides a method for a source base station to control heterogeneous network handover of a terminal and an apparatus therefor, the method comprising the steps of: determining whether to handover to a target base station using a heterogeneous network for the terminal on the basis of measurement information received from the terminal; when it is determined to handover, transmitting, to a core network entity associated with the source base station, a handover request message including identification information of the target base station; receiving, from the core network entity, a handover instruction message including evolved packet system (EPS) bearer setup list information of the target base station; and transmitting, to the terminal, the handover instruction message.
