Abstract:

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