Supporting ICN in 5G Core Network

ICN effectively delivers content, such as multimedia and IoT, by name-based routing. Recently, works on supporting ICN in 5G network have been actively studied for effective data delivery in 5G. However, they mainly focus on interworking network architecture and extended NF and interface to support ICN, and little works have been carried out for a detailed procedure supporting ICN in 5G network, to the best of our knowledge. In this paper, we propose content name registration, ICN PDU session establishment, and Interest/Data packet delivery procedures to support ICN in an extended 5G core network.
