1. A method for providing information-centric networking (ICN) service based on a 5G network:
transmitting, by a producer server, a content name prefix to all ICN routers constituting an ICN data network (DN);
requesting, by an ICN gateway (GW) connected to the 5G network among the ICN routers, registration of the content name prefix from an ICN service/network controller;
generating, by the ICN service/network controller, ICN application configuration information including an internet protocol (IP) address of the ICN GW and the content name prefix, and registering the generated ICN application configuration information to an ICN application function (AF);
requesting, by a user equipment (UE), an ICN protocol data unit (PDU) session establishment from a session management function++ (SMF++) using the content name prefix;
requesting, by the SMF++, ICN application configuration information corresponding to the content name prefix from the ICN AF, and obtaining the ICN application configuration information from the ICN AF;
selecting, by the SMF++, a user plane function (UPF) based on the ICN application configuration information and generating an IP address of each of the UE and the UPF;
establishing, by the SMF++, a PDU session between the SMF++ and the UE based on an IP address of each of the ICN GW, UE, and UPF; and
transmitting, by the UE, an interest packet requesting an ION content service to the producer server after establishing the PDU session,
wherein transmitting the interest packet comprises,
generating, by the UE, the interest packet and encapsulating the generated interest packet through an IP layer based on the IP address of the ICN GW;
transmitting the encapsulated interest packet to the ICN GW through the UPF; and
decapsulating, by the ICN GW, and transmitting the encapsulated interest packet to the producer server.
