Location-Based Prefetch and Participant-Based Prefetch

摘要

To reduce the mobile data usage, information associated with scheduled future events is prefetched via an inexpensive mass-data transfer link (e.g., Wi-Fi, Ethernet, or off-peak mobile broadband) and does not need to be fetched via an expensive mobile communication link (e.g., mobile broadband) during normal usage. Location-based prefetch and participant-based prefetch can leverage the existing infrastructures of location-based services (LBS) and social networking services (SNS).

主权项

1. A mobile device for supporting location-based prefetch, comprising:
a mass-data transfer interface for retrieving location specific information associated with a scheduled future event via a mass-data transfer link prior to said scheduled future event, wherein said location specific information provides information associated with at least a future location of said scheduled future event, and said future location is inputted by a user prior to said scheduled future event; a memory for storing said location specific information; a mobile communication interface for retrieving requested information via a mobile communication link during said scheduled future event if said requested information is absent in said memory; wherein said mobile device retrieves at least a portion of said location specific information from said memory during said scheduled future event.
