Server and method, non-transitory computer readable storage medium, and mobile client terminal and method

摘要

Systems and methods for operating in connection with mobile devices are described. The mobile devices may move between online and offline areas. In some instances, a prediction may be made as to when a mobile device will enter an offline area. The prediction may be based on sensor information. Data or a key may be transferred to the mobile device prior to entering the offline area.

主权项

1. A server for operating in connection with a client terminal, the server comprising:
circuitry configured to:
receive sensor information from the client terminal;predict, based on the sensor information and a service area map, an offline entry time at which the client terminal will enter an offline area;automatically select data for use by the client terminal while offline based on user history of the client terminal;determine a time duration needed to transmit the data to the client terminal; andinitiate transmission of the data from the server at a transmission initiation time based on the offline entry time and the time duration, wherein the transmission is performed on a limited part of the data in a range permitted for display on the client terminal.
