In-device coexistence interference report control method and apparatus of network in mobile communication system
First Claim
1. A control message transmission method of a user equipment (UE) in a mobile communication system, the method comprising:
- transmitting, to a base station, a first message including information indicating whether the UE supports an in device coexistence (IDC) indication, wherein an IDC is an interference between multiple radio transceivers in the UE;
receiving a second message including configuration information corresponding to the IDC indication;
determining whether an IDC problem is experienced in the UE; and
initiating transmission of the IDC indication, if the configuration information is set to setup and if the IDC problem is experienced in the UE.

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.
