摘要：Methods, program products, and systems for multi-tier detection of a geofenceare disclosed. In general, in one aspect, a mobile device can be configured to perform atask when the mobile device enters a geographic region. The mobile device can monitor a
current location using a multi-tiered approach. A baseband subsystem can monitor acoarse location of the mobile device using a CDMA system identifier, a CDMA networkidentifier, a CDMA zone identifier, or a CDMA base station identifier, in that order, as themobile device moves closer to the geographic region. The baseband subsystem cannotify an application subsystem when the mobile device is in a cell that intersects thegeographic region. The application subsystem can perform the task upon notification.
