Systems and Architectures for Support of High-Performance Location in a Next-Generation Radio Access Network

摘要

A Location Management Component (LMC) may be included in the gNB and connected to a gNB Central Unit (gNB-CU). A gNB-CU is any of (i) a UE via a gNB Distributed Unit (gNB-DU), (ii) another gNB via an Xn interface, or (iii) a core network entity (eg, AMF) via an NG interface. Receive location-related messages from These messages include container messages (eg, RRC container for LPP messages sent to or received from UE; NGAP container for messages sent to or received from AMF; or sent to or received from another gNB). may be transmitted in the XnAP container). The gNB-CU removes the location related messages from the container messages and forwards them to the LMC using the F1-AP container messages. Location related messages sent from the LMC to other entities are sent back via the gNB-CU using corresponding container messages.
