Abstract: 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.

Abstract: A high-accuracy positioning method and a corresponding positioning system and positioning terminal are provided, and may be used in the field of intelligent vehicle technologies. In this positioning method, a real-time kinematics (RTK) positioning technology and a multi-receiver constraint MRC positioning technology are used to determine a location of a to-be-positioned target. In this positioning method, an RTK error correction model and an MRC error correction model may be preconstructed according to a big data technology. The RTK error correction model is used to provide a correction value for an original detection value obtained based on the RTK positioning technology. The MRC error correction model is used to provide a correction value for an original detection value obtained based on the MRC positioning technology. Then, the correction values are used to calculate the location of the to-be-positioned target.

Abstract: The present disclosure provides a plastic floor, and a production apparatus and a production process of the plastic floor. At least on or near one of its edges the plastic floor includes a chamfer formed during a rolling press and plate press forming process. During the rolling press and plate press forming process of the plastic floor of the present disclosure, a chamfer is formed at the periphery on the front surface of the plastic floor. The wear-resistant layer and color film layer at the chamfer are not damaged. When splicing, the chamfers on the two pieces of plastic floor are connected to each other to form a joint seam, and there is no need to cut and chamfer the edge of the floor before grooving, thereby reducing the production process, and improving the appearance of the joint seam.

Abstract: Systems and techniques for mission critical (MC) push notification mechanism in a high-reliability (HR) information centric network (ICN) are described herein. For example, a node may test network links to other nodes to classify the other nodes into proximate nodes and non-proximate nodes based on a reception metric. The node may then elect a set of leader nodes from the proximate nodes. Here, the set of leader nodes are selected based on link quality between respective leader nodes and non-proximate nodes. The node may detect an MC event and create an ICN data packet that contains data from the MC event. The node may then transmit the ICN data packet to the set of leader nodes that then relay the ICN data packet to the non-proximate nodes.
