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 a UE capability message to a base station, the UE capability message comprising first information indicating whether the UE supports an indication indicating an in device coexistence (IDC), the IDC comprising an interference between multiple radio transceivers in the UE;
receiving a Radio Resource Control (RRC) connection reconfiguration message Including configuration information corresponding to the indication;
transmitting an RRC connection reconfiguration complete message to the base station in response to the RRC connection reconfiguration message;
determining whether an IDC problem is experienced in the UE; and
initiating transmission of the indication, if the configuration information is 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.
