Abstract
Systems and methods for measurement and reporting of average UL and DL delays and delay distributions for an NG-RAN and UPF, as well as gNB-DU DL latency, for the N3 and N9 interfaces, internal UPF delay, and between the PSA UPF and NG-RAN and between the PSA UPF and UE are described. For the UL and DL average delay and delay distributions, the measurements are split into subcounters per 5QI/QCI, S-NSSAI and/or DSCPs, with the delay distributions subcounters in bins with discrete delay ranges. The measurements aon the N3 interface delay are also differentiated between a PSA UPF and an I-UPF.
Claims20
An apparatus for a session management function (SMF), the apparatus comprising:
- processing circuitry to configure the apparatus to:
- send, to a packet data unit (PDU) session anchor (PSA) user plane function (UPF) and next generation radio access network (NG-RAN), a request to provide a plurality of measurements selected from a set of measurements that include:
- a distribution of delay downlink (DL) air-interface;
- a distribution of delay DL in a 5th generation NodeB central unit user plane (gNB-CU-UP);
- a distribution of delay DL on an F1-U interface;
- a distribution of radio link control (RLC) service data unit (SDU) packets delay on a DL within a gNB distributed unit (gNB-DU);
- a distribution of internet protocol (IP) latency in DL within the gNB-DU;
- an average round-trip delay on a N3 interface and a N9 interface on the PSA UPF and on an intermediate UPF (I-UPF);
- a distribution of round-trip delay on the N3 interface and the N9 interface on the PSA UPF and on the I-UPF;
- an average and distribution of DL and uplink (UL) General Packet Radio Service (GPRS) Tunneling Protocol (GTP) packets delay in the PSA UPF and in the I-UPF;
- and
- round-trip delay between the PSA UPF and a user equipment (UE), round-trip delay between the PSA UPF and NG-RAN, and one way delay between the PSA UPF and the NG-RAN;
- and
- receive, from the PSA UPF and NG-RAN, at least some of the measurements;
- and
- a memory configured to store the measurements.
A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors configured to provide a session management function (SMF), the one or more processors to configure the SMF to, when the instructions are executed:
- send, to a packet data unit (PDU) session anchor (PSA) user plane function (UPF) and next generation radio access network (NG-RAN), a request to provide a plurality of measurements from a set of measurements that include:
- a distribution of delay downlink (DL) air-interface;
- a distribution of delay DL in a 5th generation NodeB central unit user plane (gNB-CU-UP);
- a distribution of delay DL on an F1-U interface;
- a distribution of radio link control (RLC) service data unit (SDU) packets delay on a DL within a gNB distributed unit (gNB-DU);
- a distribution of internet protocol (IP) latency in DL within the gNB-DU;
- an average round-trip delay on a N3 interface and a N9 interface on the PSA UPF and on an intermediate UPF (I-UPF);
- a distribution of round-trip delay on the N3 interface and the N9 interface on the PSA UPF and on the I-UPF;
- an average and distribution of DL and uplink (UL) General Packet Radio Service (GPRS) Tunneling Protocol (GTP) packets delay within the PSA UPF;
- an average and distribution of DL and UL GTP packets delay within the I-UPF;
- and
- round-trip delay between the PSA UPF and a user equipment (UE), round-trip delay between the PSA UPF and NG-RAN, and one way delay between the PSA UPF and the NG-RAN;
- and
- receive, from the PSA UPF and NG-RAN, at least some of the measurements.
