Systems, devices and methods for distributed content pre-fetching in mobile communication networks

摘要

There are disclosed systems, devices, and methods for distributing pre-fetch data. A parent node obtains pre-fetch data comprising at least one of: i) data expected to be of interest to a particular user, pre-fetched by the parent node from at least one data source; and (ii) at least one identifier identifying data expected to be of interest to the particular user, for pre-fetching the identified data at a child node. The parent node selects first and second subsets of the pre-fetch data for transmission, respectively, to first and second child nodes, the selecting based on at least a predicted future location of the particular user and a respective geographic location of the first and second child nodes; and transmits the first and second subsets of the pre-fetch data, respectively, to the first and second child nodes.

1. A method at a parent node for distributing pre-fetch data to at least two child nodes, the method comprising:
obtaining pre-fetch data comprising at least one of:
(i) data expected to be of interest to a particular user, pre-fetched by the parent node from at least one data source by way of at least one data network; and(ii) at least one identifier identifying data expected to be of interest to the particular user, for pre-fetching the identified data at at least one of the child nodes; obtaining a predicted trajectory for said particular user, the predicted trajectory defining a first predicted time and location; and a second predicted time and location; selecting a first subset of the pre-fetch data for transmission to a first child node proximate the first location and a second subset of the pre-fetch data, different than the first subset, for transmission to a second child node proximate the second location, the selecting based on at least the first time and location and the second time and location; and transmitting the first subset and the second subset of the pre-fetch data, respectively, to the first child node and the second child node by way of the at least one data network.
