Abstract
A mobile station automatically determines a country in which mobile station is or will operate from readily available information, without direct assistance from the local wireless communication network. A multimode mobile station, for example, capable of both 3GPP and CDMA operation, is programmed to detect both MCC type system identifiers (from 3GPP protocol) and SID type system identifiers (from CDMA protocol) and map both types of identifiers to country identifications. However, at some locations, the SID may not uniquely map to a country. In this later case, an exemplary mobile station may identify the country by determining a local time (LTM) offset and mapping a combination of the SID obtained at the current location and the LTM offset to an identification of the country. The mobile station may use the country determination to help select a preferred network or to enable a location based device feature.
