          Native Deployment of ICN in LTE, 4G Mobile Networks
                     draft-irtf-icnrg-icn-lte-4g-00

Abstract

   LTE, 4G mobile networks use IP based transport for control plane to
   establish the data session and user plane for actual data delivery.
   In existing architecture, IP transport used in user plane is not
   optimized for data transport, which leads to an inefficient data
   delivery. IP unicast routing from server to clients is used for
   delivery of multimedia content to User Equipment (UE), where each
   user gets a separate stream. From bandwidth and routing perspective
   this approach is inefficient. Multicast and broadcast technologies
   have emerged recently for mobile networks, but their deployments are
   very limited or at an experimental stage due to complex architecture
   and radio spectrum issues. ICN is a rapidly emerging technology with
   built-in features for efficient multimedia data delivery, however
   majority of the work is focused on fixed networks. The main focus of
   this draft is on native deployment of ICN in cellular mobile networks
   by using ICN in 3GPP protocol stack. ICN has an inherent capability
   for multicast, anchorless mobility, security and it is optimized for
   data delivery using local caching at the edge. The proposed
   approaches in this draft allow ICN to be enabled natively over the
   current LTE stack comprising of PDCP/RLC/MAC/PHY or in a dual stack
   mode (along with IP) help optimize the mobile networks by leveraging
   the inherent benefits of ICN.
