Abstract: ABSTRACT “Enhancements in Namf Communication service of AMF for UE Positioning” UE positioning is the process of determining the accurate location of a mobile device within a cellular network. The Location Management Function (LMF) in the 5G Core plays a key role in the positioning process. It works with various network elements, receiving assistance and measurement data from the next-generation radio access network (NG-RAN) and the user equipment (UE) through the Access and Mobility Management Function (AMF) to accurately compute the UE's position. Positioning is supported by protocols such as LTE Positioning Protocol (LPP) and NR Positioning Protocol Annex (NRPPa) for communication between the UE and NG-RAN respectively. The LMF uses the Namf-Communication service of the AMF to communicate with both the UE and NG-RAN. The LMF can request non-UE-specific NRPPa messages to be sent to multiple NG-RAN nodes. This invention focuses on a mechanism to report partial or complete failures in NRPPa message transfer to NG-RAN nodes by the AMF. It also proposes the addition of NG- RAN identification in the NRPPa response message to the LMF, using which the LMF can provide NRPPa Error Indication to the NG-RAN node, assisting the AMF in routing it to the appropriate NG-RAN node.
