Octet 5 shall be encoded as follows:

– Bit 1 – DL (Downlink): when set to "1", this indicates a request for measuring the downlink packet delay from the UPF (PSA) to the UE.

– Bit 2 – UL (Uplink): when set to "1", this indicates a request for measuring the uplink packet delay from the UE to the UPF (PSA).

– Bit 3 – RP (Round Trip): when set to "1", this indicates a request for measuring the round trip packet delay between the UPF (PSA) and UE.

– Bit 4 – GTPUPM (GTP-U Path Monitoring):

– when set to "1, this indicates that the Downlink, Uplink or Round Trip delay shall be measured by using GTP-U path monitoring, i.e. by the I-UPF reporting the one-way end to end accumulated transport delay in UL GTP-U packets towards the PSA; see clause 5.33.3.3 of 3GPP TS 23.501 [28];

– when set to "0", this indicates that the Downlink, Uplink or Round Trip delay shall be measured by using RAN and UPF time information in GTP-U packets; see clause 5.33.3.2 of 3GPP TS 23.501 [28].

– Bit 5 to 8: Spare, for future use and set to "0".

At least one bit shall be set to "1". Several bits may be set to "1".
