Abstract
Location-based services are provided in a communication system comprising at least a portion of at least one wireless network. In one aspect of the invention, mobile user devices that are candidates for a location-based service are identified and the identified mobile user devices are monitored to determine when one or more of said mobile user devices becomes currently active on a traffic channel of the wireless network. Location information is automatically obtained for the one or more mobile user devices that are currently active on the traffic channel, and delivery of at least one message to a given one of those mobile user devices is controlled based on the location information. Generation of location queries involving respective ones of the mobile user devices is thereby synchronized with the traffic channel activity of those devices.
