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).

The purpose of the UE policy section management result information element is to transfer from the UE to the PCF information about instructions for UE policy section management which the UE could not execute successfully.

The UE policy section management result information element is coded as shown in figure D.6.3.1, figure D.6.3.2, figure D.6.3.3, figure D.6.3.4, figure D.6.3.5 and table D.6.3.1.

The UE policy section management result information element has a minimum length of 12 octets and a maximum length of 65534 octets.

Value part of the UE policy section management result information element (octets 4 to z)
The value part of the UE policy section management result information element consists of one or several UE policy section management subresults.
UE policy section management subresult:
Number of results (octet d)
This field contains the binary encoding of number of results included in the UE policy section management subresult.
MCC, Mobile country code (octet d+1, and bits 4 to 1 of octet d+2)
The MCC field is coded as in ITU-T Recommendation E.212 [42], annex A.
MNC, Mobile network code (bits 8 to 5 of octet d+2, and octet d+3)
The coding of this field is the responsibility of each administration but BCD coding shall be used. The MNC shall consist of 2 or 3 digits. If a network operator decides to use only two digits in the MNC, MNC digit 3 shall be coded as "1111". (NOTE)
UE policy section management subresult contents (octets d+4 to y)
The UE policy section management subresult contents consist of one or several results.
Result (octet f to f+4)
UPSC (octet f to f+1)
This field contains the binary encoding of the UPSC. The value of the UPSC is set by the PCF
Failed instruction order (octets f+2 to f+3)
This field contains the binary encoding of the order of the instruction in the UE policy section management sublist contents as specified in Figure D.6.2.4, which could not be executed successfully. The value of failed instruction order set to one indicates that the first instruction in the UE policy section management sublist contents could not be executed successfully.

01101111Protocol error, unspecified
The receiving entity shall treat any other value as 0110 1111, "Protocol error, unspecified".
NOTE: The UE operating in the SNPN access operation mode shall include the PLMN ID part of the SNPN identity of the SNPN in the UE policy section management subresult.
