Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).
The purpose of the UE-DS-TT residence time information element is to signal the time taken within the UE and the DS-TT to forward a packet i.e. between the ingress of the UE and the DS-TT port in the DL direction, or between the DS-TT port and the egress of the UE in the UL direction.
The UE- DS-TT residence time information element is coded as shown in figure 9.11.4.26.1 and table 9.11.4.26.1.
The UE-DS-TT residence time is a type 4 information element with a length of 10 octets.

| UE-DS-TT residence time contents (octets 3 to 10)The UE-DS-TT residence time contents contain the UE-DS-TT residence time encoded as specified for the correctionField in IEEE Std 1588-2019 [43B], with the LSB bit of the first octet of the UE-DS-TT residence time included in bit 1 of octet 3. If the UE-DS-TT residence time.is too big to be represented, all bits of octets 3 to 10 shall be coded as "1" except the MSB bit of octet 10. |
