Claim 13:
14. A management system configured provide key performance indicators (KPIs) in a fifth generation (5G) system, the system comprising:
a service producer for KPIs for at least one of a sub-network, network slice subnet, or network slice comprising processing circuitry and memory configured to:
collect, from a plurality of service producers, performance measurements of at least one of next generation radio access networks (NG-RANs) or 5G core network (5GC) contained by or associated to at least one of a sub-network, network slice subnet, or network slice, the performance measurements including packet delays that include uplink (UL) and downlink (DL) delays associated with each new radio (NR) cell distributed unit (NR cell DU) and delays associated with a 5th generation NodeB (gNB) central unit (CU) user plane (UP) (gNB-CU-UP) of each of the NG-RANs, or delays associated with each user plane function (UPF); and
generate KPIs based on the performance measurements collected by the service producer for KPls, the KPIs including at least one of integrated average UL and DL packet delays, gNB DU delays or end-to-end (e2e) delays for the at least one of the sub-network, network slice subnet, or network slice that are dependent on:
an overall DU delay that comprises an air interface delay of an air interface between the NR cell DU and a user equipment (UE) connected to the NR cell DU and a NR cell DU delay within the NR cell DU, and
an overall gNB CU delay that comprises an F1 delay on an F1 interface and a gNB CU delay within the gNB-CU-UP, or
an e2e packet delay between the UPF and the UE,

wherein the KPIs further include average UL and average DL packet delays of NR cell DUs in a gNB DU, each of average UL and DL delays comprise an overall NR cell DU delay, and the KPIs are based on weighting of the overall NR cell DU delay using independent weights for UL and DL packets, the weights for each NR cell DU being independent.
