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

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.
