WIRELESS COMMUNICATION SYSTEM, BASE STATION APPARATUS, TERMINAL APPARATUS, WIRELESS COMMUNICATION METHOD, AND INTEGRATED CIRCUIT

摘要

A wireless communication system includes a first base station apparatus and a second base station apparatus, and a terminal apparatus, each of the first base station apparatus and the second base station apparatus communicating with the terminal apparatus via a plurality of cells. The first base station apparatus notifies the second base station apparatus of a message that indicates a connection change request to change a connection destination of the terminal apparatus from the second base station apparatus to a third base station apparatus. Upon receiving the message indicating the connection change request, the second base station apparatus notifies the third base station apparatus of a connection request to connect the third base station apparatus to the terminal apparatus. The second base station apparatus determines whether to include terminal information of the terminal apparatus in the message indicating the connection request, based information included in the message indicating the connection change request.
