Abstract
A mobile device can store a set of first CDMA identifiers including, for example, system identifiers, network identifiers, or zone identifiers. Each first CDMA identifier can be associated with a first geographic location. The mobile device can determine a current location by matching a current first CDMA identifier with a stored first CDMA identifier. If a user desires a current location that has finer granularity, the mobile device can retrieve a set of second CDMA identifiers including, for example, base station identifiers. Each second CDMA identifiers can be associated with a second geographic location that has a finer granularity than that of the first geographic location. The mobile device can match a current second CDMA identifier from the retrieved second CDMA identifiers and designate the second geographic location associated with the matching second CDMA identifier as the current location that has the finer granularity.
