Title: Monitoring boundary crossings in a wireless network

Abstract: A method of providing location-based services for a mobile unit operating in a wireless network including network structures. The method includes receiving an identifier associated with the mobile unit. The method also includes monitoring a location of the mobile unit using the identifier and a network-assisted location finding system to identify a crossing of a service zone boundary by the mobile unit. The service zone boundary is defined by reference to at least one of the network structures. The service zone boundary also corresponds to a geographic zone boundary. The method further includes transmitting service information to a system user in response to the crossing of the service zone boundary.
