Method and apparatus for reducing interference between two different communication modules

摘要

A method for avoiding interference in an idle mode and a method for receiving a public warning system message regardless of an operation mode when different wireless communication modules coexist in a terminal in a wireless communication system are provided. The method for controlling an idle mode of a terminal in a wireless communication system includes determining whether interference occurs between heterogeneous communication modules of the terminal; and limiting, if the interference occurs between the heterogeneous communication modules, camping on a corresponding frequency of the communication module in which the interference occurs. The terminal can maximally avoid the interference in the idle mode to operate without malfunction, and correctly receive the public warning system message regardless of the operation mode to enable the user to timely receive the corresponding message.

1. A method of controlling an idle mode of a terminal in a wireless communication system, comprising:
determining whether interference occurs between a first transceiver for cellular network and a second transceiver for ISM (industrial, scientific and medical) network that are heterogeneous communication modules of the terminal; and limiting, if the interference occurs between the heterogeneous communication modules, camping on a corresponding frequency of the communication module in which the interference occurs; limiting transmission and reception of the second transceiver in a sub-frame required to receive a paging message by the first transceiver; receiving the paging message after the limiting of camping; determining whether earthquake and tsunami warning system (ETWS) or commercial mobile alert system (CMAS) indication is included in the received paging message; confirming, if the indication is included in the paging message, scheduling information; and limiting transmission and reception of the communication module in which the interference occurs based on the scheduling information.
