Section: D.2.1.4 Network-requested UE policy management procedure not accepted by the UE
Content: If the UE could not execute all instructions included in the UE policy section management list IE successfully, the UE shall: a) set the PTI IE to the PTI value received within the MANAGE UE POLICY COMMAND message and encode the results by including: 1) the UPSI associated with the instructions which could not be executed successfully; 2) the failed instruction order set to order of the instruction in the UE policy section management sublist of the received UE policy section management list IE which could not be executed successfully; and 3) the cause of the failure, in the UE policy section management result IE as specified in subclause D.5.3 and include it in a MANAGE UE POLICY COMMAND REJECT message, and b) transport the MANAGE UE POLICY COMMAND REJECT message using the NAS transport procedure as specified in subclause 5.4.5. Upon receipt of the MANAGE UE POLICY COMMAND REJECT message, the PCF shall stop timer T3501. Any instruction that was included in the UE policy section management list IE but not indicatedin the UE policy section management result IE of the received MANAGE UE POLICY COMMAND REJECT message, shall be considered as successfully executed. 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. Upon receipt of the notification from the AMF that the UE is not reachable, the PCF shall stop the T3501.
