Method for controlling mobility of terminal in heterogeneous network and apparatus therefor

Abstract:

Provided are a method and an apparatus for performing a mobility control procedure of a terminal, by a master base station. The method includes: determining starting of a secondary node addition procedure for setting a terminal context for a secondary node in order to provide the terminal with a radio resource of the secondary node; transmitting, to the secondary node, a secondary base station addition request message for requesting radio resource allocation for a specific E-UTRAN radio access bearer (E-RAB); and receiving, from the secondary node, secondary cell group radio resource configuration information to be additionally configured in the terminal.
