Native Deployment of ICN in LTE, 4G Mobile Networks
draft-irtf-icnrg-icn-lte-4g-03
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.
