Abstract

There is disclosed a system for transmitting data to users. The system includes nodes interconnected by at least one data network. The nodes are organized hierarchically to comprise a root node and at least two child nodes. The data transmission characteristics of communication with each of the child nodes are different. The root node is configured to: receive data transmission preferences of a particular user; receive data to be transmitted to the particular user; and transmit a selected subset of the data to at least one of the child nodes. The subset selected based on at least the received data transmission preferences and the data transmission characteristics, to permit the particular user to obtain data from the child nodes according to the data transmission preferences. The at least one of the child nodes being configured to: receive data from the root node; and transmit at least part of the received data to the user.

First claim

What is claimed is:

1. A system for pre-fetching content data for transmission to a mobile device of a particular user, the system comprising:
a plurality of nodes interconnected by at least one data network;
the plurality of nodes organized hierarchically to comprise a root node and at least two child nodes, each of the plurality of nodes capable of data transmission with differing data transmission characteristics;
the root node comprising at least one processor in communication with a network interface being configured to:
receive data use preferences of the particular user of the mobile device;
pre-fetch content data from one or more content sources to be transmitted to the mobile device of the particular user in accordance with a content list associated with the particular user; and
transmit a selected subset of the pre-fetched content data to one of the at least two child nodes, the subset selected based on at least the received data use preferences and the data transmission characteristics of each of the at least two child nodes; and

the at least one of the child nodes being configured to:
receive the selected subset of pre-fetched content data from the root node; and
transmit at least part of the selected subset of pre-fetched content data to the user.

2. The system of claim 1 , wherein the data use preferences are cost preferences.

3. The system of claim 1 , wherein the data use preferences are content preferences.

4. The system of claim 1 , wherein the subset of the pre-fetched content data is selected based on at least one of: a predicted future location of the user, a geographic location of that child node to which the subset is sent, how soon content is needed, quantity of content, traffic associated with other users, content security requirements, and network security characteristics.

5. The system of claim 1 , wherein at least one of the child nodes is instantiated at a location selected based on at least one of: the data transmission characteristics, the data use preferences, a predicted future location of the user, a geographic location of that child node to which the subset is sent, how soon content is needed, quantity of content, traffic associated with other users, content security requirements, and network security characteristics.

6. The system of claim 1 , wherein the root node is configured to:
determine data characteristics of the pre-fetched content data; and
select the subset of pre-fetched content data based on at least the determined data characteristics.

7. The system of claim 1 , wherein the content list comprises one or more content items expected to be of interest to the particular user.

8. The system of claim 7 , wherein the content list comprises one or more content items expected to be of interest to the particular user in a future.

9. The system of claim 7 , wherein the root node is configured to update the one or more content items included in the content list based on new content interests predicted for the user.

10. The system of claim 1 , wherein the subset of the pre-fetched content data is transmitted to the one of the at least two child nodes without receiving a request from the mobile device of the particular user.

11. The system of claim 1 , wherein the root node is configured to populate the content list based on one of: content interests predicted for the particular user; content interests expressed by the particular user; and an application executing at the mobile device of the particular user.

12. The system of claim 1 , wherein root node is configured to assign priorities to portions of the pre-fetched content data based on one of: a mobility prediction for the particular user; a likelihood that the particular user will access the content data at a particular location; and the data transmission preferences.

13. A method for pre-fetching content data for transmission to a mobile device of a particular user, the method comprising:
at a parent node interconnected by a at least one data network with at least two child nodes, each of the nodes capable of data transmission with differing data transmission characteristics:
receiving data use preferences of the particular user of the mobile device;
pre-fetching content data from one or more content sources to be transmitted to the mobile device of the particular user in accordance with a content list associated with the particular user; and
transmitting a selected subset of the pre-fetched content data to one of the at least two child nodes, the subset selected based on at least the received data use preferences and the data transmission characteristics of each of the at least two child nodes; and

at the at least one of the child nodes:
receiving the selected subset of pre-fetched content data from the parent node; and
transmitting at least part of the selected subset of pre-fetched content data to the user.

14. The method of claim 13 , further comprising:
at the parent node, receiving data transmission characteristics for at least one of the child nodes.

15. The method of claim 13 , further comprising:
at the parent node:
determining data characteristics of the pre-fetched content data;
selecting the subset of the pre-fetched content data based on at least the determined data characteristics.

16. The method of claim 13 , wherein the content list comprises one or more content items expected to be of interest to the particular user.

17. The method of claim 16 , wherein the content list comprises one or more content items expected to be of interest to the particular user in a future.

18. The method of claim 16 , wherein the root node is configured to update the one or more content items included in the content list based on new content interests predicted for the user.

19. The method of claim 16 , wherein the content list comprises one or more content items expected to be of interest to the particular user in a future.

20. The method of claim 13 , wherein the subset of the pre-fetched content data is transmitted to the one of the at least two child nodes without receiving a request from the mobile device of the particular user.

21. The method of claim 13 , wherein the root node is configured to populate the content list based on one of: content interests predicted for the particular user; content interests expressed by the particular user; and an application executing at the mobile device of the particular user.

22. The method of claim 13 , wherein root node is configured to assign priorities to portions of the pre-fetched content data based on one of: a mobility prediction for the particular user; a likelihood that the particular user will access the content data at a particular location; and the data transmission preferences.

23. A method at a parent node for pre-fetching content data for transmission to a mobile device of a particular user by way of at least two child nodes, each of the parent node and the at least two child nodes capable of data transmission with differing data transmission characteristics, the method comprising:
receiving data use preferences of the particular user of the mobile device;
pre-fetching content data from one or more content sources to be transmitted to the mobile device of the particular user in accordance with a content list associated with the particular user; and
transmitting a selected subset of the pre-fetched content data to one of the at least two child nodes, the subset selected based on at lea
