The LN Core is the engine of the LocalNavigator, generating location events for a
predefined area. When a mobile device, such as a PDA or mobile phone, changes location,
the LN Core checks if any of the location-based events in which clients have expressed an
interest have occurred. If they have, the LN Core sends notifications to the interested
client(s). The LN Core provides two general types of service, firstly delivering
notifications when a certain location event occurs, e.g tell me when Jane enters her
office, or secondly processing a wide range of explicit location queries from the
client, e.g. where is Jane now?. See picture of Platform Diagram.
