1. A method, comprising:establishing a wireless connection with a User Equipment (UE) via a first system, the first system corresponding to a mobile communication system, wherein the UE supports the first system and a second system;
transmitting a first message to a Target Base Station (TBS), by a Source Base Station (SBS), wherein the first message is a handover request message, wherein the first message includes Time Division Multiplexing (TDM) information related to avoidance of In-Device Coexistence (IDC) interference of the UE, wherein the TDM information related to the avoidance of IDC interference by the UE includes TDM pattern information, wherein the TDM pattern information corresponds to information on a subframe pattern in a bitmap form;
receiving a response to the first message from the TBS, by the SBS; and
transmitting a second message to the UE, by the SBS, for handover to the TBS.
