Abstract:
1. A server for operating in connection with a mobile client terminal as part of a communication network, the server comprising: a processing unit; an input configured to receive sensor information from the client terminal; memory storing instructions which, when executed by the processing unit, cause the processing unit to determine a current location and path of the client terminal based at least partially on the sensor information and predict, based at least partially on the current location and path of the client terminal, a time at which the client terminal will enter an offline area by comparing the location and path to a service area map; and an output configured to transmit to the client terminal (a) data to be used by the client terminal while offline; or (b) a key to decrypt data stored on the client terminal, wherein the instructions, when executed, cause the processing unit to determine a time duration needed to transmit to the client terminal the (a) data to be used by the client terminal while offline; or (b) a key to decrypt data stored on the client terminal, and wherein the instructions, when executed, initiate transmission of the (a) data to be used by the client terminal while offline; or (b) key to decrypt data stored on the client terminal prior to the time at which the client terminal is predicted to enter the offline area by at least the duration, wherein the server is configured to store the data to be used by the client terminal while offline, and wherein the data to be used by the client terminal while offline is automatically designated as being for use while offline based on user history of the client terminal.
