D.2.1.3 Network-requested UE policy management procedure accepted by the UE

Taught in 5. Finding your way around TS 24.501 (CT1 — the group that writes what your phone says, in depth), 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).

If all instructions included in the UE policy section management list IE were executed successfully by the UE, the UE shall:

create a MANAGE UE POLICY COMPLETE message including the PTI value received within the MANAGE UE POLICY COMMAND message; and
transport the MANAGE UE POLICY COMPLETE message using the NAS transport procedure as specified in clause 5.4.5.

Upon receipt of the MANAGE UE POLICY COMPLETE message, the PCF shall stop timer T3501. The PCF should ensure that the PTI value assigned to this procedure is not released immediately.

NOTE: The way to achieve this is implementation dependent. For example, the PCF can ensure that the PTI value assigned to this procedure is not released during the time equal to or greater than the default value of timer T3501.
