Abstract
A current location of a mobile system in a wireless network can be determined by using information provided by a base station in communication with the mobile system. The information can include a system identifier (SID) table and a local time offset (LTM_OFF) value and a daylight savings time (DAYLT) value. The SID table is used to provide a mobile country code (MCC) associated with a country in which the mobile device is located. The LTM_OFF value is used to provide a range of longitude values in which the mobile device is located. The current location of the mobile device is based upon at least the range of longitude values and the current country. The current location is used to build an optimized scan list that is used, in turn, to identify and acquire access to the preferred system by a mobile device.
