Abstract
An in-device coexistence interference report control method of a network for terminal to inform the network of interference among heterogeneous radio communication modules coexisting in the terminal is provided. The method includes determining, at a terminal when a terminal capability enquiry message is received from a base station, whether the base station supports an In-Device Coexistence (IDC) interference report, transmitting, when the IDC interference report is supported, a terminal capacity information message to the base station, receiving a Radio Resource Control (RRC) connection reconfiguration message including information on whether terminal's IDC interference indicator transmission is permitted from the base station; and transmitting an RRC connection reconfiguration complete message to the base station in response to the RRC connection reconfiguration message. The in-device coexistence interference indication control method is advantageous in preventing the UE from transmitting useless in-device coexistence interference indication messages, resulting in reduction of unnecessary signaling.
