Claim 16:
17. A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a service producer for key performance indicators (KPIs) in a fifth generation (5G) system, the one or more processors to configure the service to, when the instructions are executed:
collect performance measurements of next generation radio access networks (NG-RANs) and a 5G core network (5GC) contained by or associated to at least one of a sub-network, network slice subnet, or network slice from a plurality of service producers, the performance measurements including packet delays for each gNB of each of the NG-RANs and packet delays for each 5GC, the packet delays for each gNB including uplink (UL) and downlink (DL) delays associated with a 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), and the packet delays for 5GC associated with a user plane function (UPF); and
generate KPIs for the at least one of a sub-network, network slice subnet, or network slice based on the performance measurements of at least one of the NG-RANs or 5GC, the KPIs including at least one of integrated average UL and DL packet delays in the NG-RANs, gNB DU delays, or end-to-end (e2e) delays, the integrated average UL and DL packet delays dependent on:
an overall gNB 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,, wherein:
the KPIs of integrated packet delays in the at least one of the NG-RANs are based on weighting of an overall NR Cell DU delay and the overall gNB CU delay using a first weight for the overall NR Cell DU delay and a second weight for the overall gNB CU delay,
the weighting of the overall NR Cell DU delay and the overall gNB CU delay for UL and DL packets are independent,
the first weight comprises at least one of:
user plane data volume of a NR cell in a gNB DU,
user plane Packet Data Convergence Protocol (PDCP) data volume of a NR cell in a gNB CU
number of user plane PDCP packets of the NR cell in the gNB CU,
number of user plane radio link control (RLC) packets of the NR cell in the gNB DU, or
number of user plane transport blocks (TBs) of the NR cell in the gNB DU, the second weight comprises at least one of:
user plane data volume of the gNB-CU-UP, or
number of user plane PDCP packets of the gNB-CU-UP,

the KPIs of e2e packet delays in NG-RAN are based on weighting of transmissions over N3 and N9 interfaces using independent weights for UL and DL packets and for the N3 and N9 interfaces,
an N3 weight comprises at least one of:
number of octets of incoming or outgoing general packet radio service (GPRS) Tunnelling Protocol (GTP) data packets on the N3 interface, or
number of incoming or outgoing GTP data packets on the N3 interface, and an N9 weight comprises at least one of:
number of octets of incoming or outgoing GTP data packets on the N9 interface, or
number of incoming or outgoing GTP data packets on the N9 interface.
