Abstract
The invention relates to a method for detecting a home area in a mobile station, and to a mobile station realizing the invention. According to the invention the home area is detected in the mobile station by comparing (8) data received by the mobile station from the base stations of a cellular network with predetermined (1 to 6) home area data stored in the mobile station. The home area data is determined (1 to 6) based on preferably all of the following data: a) a mobile country code (MCC), b) a mobile network code (MNC), c) a location area code (LAC) and a related cell identity (CI) for all broadcasting channels (BCCH) which the base station is able to receive, d) received signal strengths (RSS) for all broadcasting channels BCCH, e) distances from all base stations (BTS) on the broadcasting channels BCCH, and f) timing advances (TA).
