Abstract

Methods, devices, and systems for information selection in a wireless communication system are provided. In one embodiment, a method of information selection in a wireless communication system comprises receiving a selection request signal by a propagator node, wherein the selection request signal identifies information requested by a selector node; determining all or a portion of the selection request signal matches all or a portion of an information tag stored in an information cache of the propagator node, wherein the information tag is associated with an information datagram; and forwarding the information datagram from the propagator node to the selector node, wherein the information datagram contains all or a portion of the information.

Claims

1. A method of information selection in a wireless communication system performed on a propagator node, comprising:

receiving an information datagram from an information distribution gateway (IDG) node in response to a first selection request signal, wherein said IDG node received said information datagram from an information repository, and wherein said information datagram comprises an information tag;

storing said information datagram in an information cache;

receiving a second selection request signal via an access point, wherein said selection request signal identifies information requested by a selector node;

determining all or a portion of said second selection request signal matches all or a portion of said information tag stored in said information cache; and

forwarding said information datagram to said selector node as a result of the match, wherein said information datagram contains all or a portion of said information.

2. The method of claim 1, wherein said receiving a second selection request signal includes receiving said second selection request signal over a neighbor interface module of said propagator node, wherein said neighbor interface module is directly or indirectly associated with said selector node, and wherein said forwarding said information datagram to said selector node includes forwarding said information datagram over said neighbor interface module.

3. The method of claim 1, further comprising discarding, removing, or overwriting said second selection request signal.

4. The method of claim 1, wherein said second selection request signal includes a selector tag.

5. The method of claim 1, wherein said second selection request signal is a persistent selection request signal.

6. The method of claim 1, wherein said second selection request signal includes an unqualified information object identifier.

7. The method of claim 1, wherein said second selection request signal includes a qualified information object identifier.

8. The method of claim 1, wherein said second selection request signal, said information datagram, or both includes a session initiation protocol (“

SIP”

) signaling message.

9. The method of claim 1, wherein said second selection request signal, said information datagram, or both includes a hypertext transfer protocol (“

HTTP”

) signaling messages.

10. The method of claim 1, wherein said second selection request signal is cryptographically signed.

11. A method of information selection in a wireless communication system, comprising:

receiving an information datagram by a propagator node from an information distribution gateway (IDG) node coupled to the Internet, wherein said information datagram includes an information tag;

determining all or a portion of said information tag matches all or a portion of a selection tag stored in a selection routing table of said propagator node, wherein said selection tag is associated with a selector node; and

forwarding said information datagram from said propagator node to said selector node via an access node.

12. The method of claim 11, further comprising:

determining all or a portion of said information tag matches all or a portion of one or more selection tags stored in said selection routing table of said propagator node, wherein each of said selection tags is associated with a selector node; and

forwarding said information datagram from said propagator node to one or more of said matched selector nodes.

13. The method of claim 11 further comprising:

determining said selection tag stored in said selection routing table of said propagator node is not a persistent selection request signal; and

discarding, removing, or overwriting said information selection signal from said selection routing table.

14. A device acting as a propagator node for information selection in a wireless communication system, comprising:

a first neighbor interface module configured to receive an information datagram from an information distribution gateway (IDG) node in response to a first selection request signal, wherein said IDG node received said information datagram from an information repository, and wherein said information datagram comprises an information tag;

a second neighbor interface module configured to receive a second selection request signal from a selector node via an access point, wherein said second selection request signal identifies information requested by a selector node;

a memory configured to store an information cache comprising said information datagram; and

a controller coupled to said second neighbor interface module and coupled to the memory, wherein said controller is configured to;

determine all or a portion of said second selection request signal matches all or a portion of said information tag stored in said information cache; and

forward said information datagram from said propagator node to said selector node as a result of the match, wherein said information datagram contains all or a portion of said information.

15. The device of claim 14, wherein said first neighbor interface module is directly or indirectly associated with said IDG node, and wherein said second neighbor interface module is directly or indirectly associated with said selector node.
