Patent ID: 8228816

Claim:
A method of detecting a link balance of coverage of a down link and an up link in a mobile communication system, the method comprising: setting a minimum receiving signal code power based on system information received from a base station; setting a maximum terminal Tx power for transmitting radio wave to the base station from a communication terminal in accordance with the minimum receiving signal code power; setting a reference value of a link balance detection quotient for detecting whether the up link and down link coverage has a defect based on calculation of the minimum receiving signal code power and the maximum terminal Tx power; measuring a receiving signal code power and a terminal Tx power of the communication terminal; detecting the balance of the down link and up link coverage based on comparison of the reference value of the link balance detection quotient with a value calculated in accordance with the measured receiving signal code power and terminal Tx power; and transmitting information of link balance state for the balance of the down link and up link coverage to an operating device of the mobile communications system.
