Abstract

In one embodiment, a method for improving content delivery for a user equipment (UE) is implemented on a computing device and includes: receiving a request from an application layer on the UE, determining whether said request is an ICN-based request using Information Centric Networking (ICN) transport protocol or an IP-based request using Internet Protocol (IP) transport protocol, and for each ICN-based request according to the determining: forwarding the ICN-based request to an ICN function on the UE, and compressing ICN headers in the ICN-based request using robust header (RoHC) compression.

Claims

1. A user equipment (UE) comprising:

a processor; and

a protocol stack operative to be used by said processor comprising;

an application layer,

an Information Centric Networking (ICN) transport function,

a forwarding agent, wherein said forwarding agent is operative to receive ICN-based requests and Internet Protocol (IP) based requests from said application layer, and to forward said ICN-based requests to said ICN transport function, and

a Packet Data Convergence Protocol (PDCP) operative to receive said ICN-based requests from said ICN transport function, and forward said ICN-based requests to a Radio Link Control (RLC) protocol.

2. The UE according to claim 1 and wherein said protocol stack further comprises:

an IP transport function implemented in parallel to said ICN transport function, wherein;

said forwarding agent is further operative to forward said IP based requests to said IP transport function;

said ICN transport function is operative to forward said ICN-based requests to said IP transport function; and

said IP transport function is operative to forward said ICN-based requests as ICN over IP to said PDCP.

3. The UE according to claim 2 and wherein said forwarding agent is further operative to:

receive ICN+IP requests from said application layer, wherein said ICN+IP requests are associated with both said ICN transport protocol and said IP transport protocol;

determine a preferred transport protocol from among said ICN transport protocol and said IP transport protocol according to parameters for limiting network resource usage; and

forward said ICN+IP requests according to said preferred transport protocol.

4. The UE according to claim 1 and wherein:

said ICN transport function is implemented as native ICN without implementation of an IP transport function in said protocol stack; and

said forwarding agent is operative to send said IP based requests to said ICN transport function.

5. The UE according to claim 1 and wherein said PDCP is further operative to use robust header (RoHC) compression to compress headers in said ICN-based requests.

6. The UE according to claim 1 and wherein Non-Access Stratum (NAS) signaling for said UE is IP-based.

7. The UE according to claim 1 and wherein said UE is operative to communicate via a Long Term Evolution (LTE) network.

8. A method for improving content delivery for a user equipment (UE), the method implemented on a computing device and comprising:

receiving a request from an application layer on said UE;

determining whether said request is an ICN-based request using Information Centric Networking (ICN) transport protocol or an IP-based request using Internet Protocol (IP) transport protocol; and

upon determining that said request comprises an ICN-based request;

forwarding said ICN-based request to an ICN transport function, on said UE, and

compressing ICN headers in said ICN-based request using robust header (RoHC) compression.

9. The method according to claim 8 and further comprising:

receiving content from a content distribution network (CDN) via said ICN transport protocol.

10. The method according to claim 9 and wherein said receiving content comprises receiving said content from a cache on an ICN-enabled mobile base station.

11. The method according to claim 9 and wherein said receiving content comprises receiving said content from a cache on an ICN-enabled evolved packet core (EPC) gateway.

12. The method according to claim 9 and wherein said content is received from an ICN multicast to more than one said UE.

13. The method according to claim 8 and further comprising:

indicating in an initial attach request sent by said UE that said UE is ICN capable.

14. The method according to claim 13 and wherein said indicating is via insertion of an ICN indication in a Protocol Configuration Option Information Element (PCO IE) field in said initial attach request.

15. The method according to claim 14 and wherein said initial attach request is associated with attaching to a Long Term Evolution (LTE) mobile network.

16. The method according to claim 8 and further comprising receiving an assigned ICN name upon success of said initial attach request.

17. The method according to claim 8 and further comprising overlaying, said ICN-based request over said IP transport protocol, wherein said UE is implemented with support for both said ICN transport protocol and said IP transport protocol.

18. The method according to claim 8 and further comprising:

using said ICN transport protocol for content delivery; and

using said IP transport protocol for Non-Access Stratum (NAS) signaling.

19. The method according to claim 8 and wherein:

said receiving comprises receiving ICN+IP requests from said application layer, wherein said ICN+IP requests are associated with both said ICN transport protocol and said IP transport protocol; and

said determining comprises determining a preferred transport protocol from among said ICN transport protocol and said IP transport protocol according to parameters for limiting network resource usage.

20. A user equipment (UE) comprising:

means for receiving a request from an application layer on said UE;

means for determining whether said request is an ICN-based request using Information Centric Networking (ICN) transport protocol or an IP-based request using Internet Protocol (IP) transport protocol;

means for forwarding each said ICN-based request to an ICN function on said UE; and

means for compressing ICN headers in said each ICN-based request using robust header (RoHC) compression.
