1. An apparatus configured to operate as a service producer for key performance indicators (KPIs) in a fifth generation (5G) system, the apparatus comprising:
processing circuitry configured to:
collect next generation radio access network (NG-RAN) performance measurements of at least one NG-RAN or 5G core network (5GC) from at least one service producer for measurements, the NG-RAN performance measurements including packet delays for the at least one NG-RAN that include delays associated with a 5G NodeB (gNB) distributed unit (gNB DU) and delays associated with a gNB central unit (CU) user plane (UP) (gNB-CU-UP) of the at least one NG-RAN, the 5GC performance measurements including end-to-end (e2e) packet delay between a Packet Data Unit Session Anchor User Plane Function (PSA UPF) and user equipment (UE); and
generate KPIs for at least one of a sub-network, a network slice subnet, or a network slice based on at least one of the NG-RAN performance measurements or the 5GC performance measurements, the KPIs including integrated delays, gNB DU delays, and e2e delays, the integrated delays dependent on: a delay in a new radio (NR) cell DU, a delay between the NR cell DU and a user equipment (UE) connected to the NR cell DU, a delay between the NR cell DU and the gNB-CU-UP, and a delay in the gNB-CU-UP, network resources of the 5G system adjusted to improve the KPIs based on at least one of the NG-RAN performance measurements or the 5GC performance measurements; and
a memory configured to store the NG-RAN performance measurements.
