Abstract
An embodiment provides a method for communicating location-based information between an application server and a mobile device in response to an information query, the mobile device and the application server communicating via a communication network, the method comprising the steps of: initially transmitting a subset of the location-based information to the mobile device in response to the information query; transmitting further subsets of the location-based information as required; and pre-caching a predefined amount of location-based information at the device in response to a pre-cache trigger notification, the pre-cache trigger notification being generated when it is determined that the mobile device may lose contact with the communication network.
