Abstract
A method for measuring a position includes: allocating a first ranging code and a first ranging region for a mobile station; receiving a second ranging code and allocation information on a second ranging region of the mobile station from a neighboring base station; transmitting the first ranging code and the second ranging code to the mobile station; receiving the first ranging code from the mobile station in the first ranging region; calculating a received timing adjustment value of the first ranging code; receiving a received timing adjustment value of the second ranging code from the neighboring base station; and measuring the position of the mobile station according to the received timing adjustment value of the first ranging code and the received timing adjustment value of the second ranging code. Therefore, the cost and efficiency can be improved by measuring the position of the mobile station by changing the ranging method used in the conventional system.
