Information centric network unstructured data carrier
System and techniques for information centric network unstructured data carrier are described herein. A user plane function (UPF) node receives an initiation for a packet data unit (PDU) session of user equipment (UE). Here, the initiation includes an indication for an ICN session and a PDU session identification (ID). The PDU session may then map the PDU session to the PDU session ID in an ICN routing data structure. Here, the ICN routing data structure is one or both of the pending interest table (PIT) or the forwarding interest base (FIB) of the UPF node. An ICN packet (interest or data packet) may be from the UE contained within a PDU on from the PDU session that conforms to an unstructured-data classification as defined by a 3GPP 5G family of standards. The ICN packet is extracted from the PDU and routed in accordance with the ICN routing data structure.
