D.6.2 UE policy section management list

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 list information element is to transfer from the PCF to the UE a list of instructions to be performed at the UE for management of UE policy section stored at the UE.

The UE policy section management list information element is coded as shown in figure D.6.2.1, figure D.6.2.2, figure D.6.2.3, figure D.6.2.4, figure D.6.2.5, figure D.6.2.6, figure D.6.2.7 and table D.6.2.1.

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

Table D.6.2.1: UE policy section management list information element

Value part of the UE policy section management list information element (octets 4 to z)
The value part of the UE policy section management list information element consists of one or several UE policy section management sublists.
UE policy section management sublist:
Length of UE policy section management sublist (octets d to d+1)
This field contains the binary encoding of the length of the UE policy section management sublist in units of octets.
MCC, Mobile country code (octet d+2, and bits 4 to 1 of octet d+3)
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+3, and octet d+4)
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 1)
UE policy section management sublist contents (octets d+5 to y)
The UE policy section management sublist contents consist of one or several instructions.
Instruction:
Instruction contents length (octets d+5 to d+6)
This field contains the binary encoding of the instruction contents length in units of octets.
UPSC (octets d+7 to d+8)
This field contains the binary encoding of the UPSC. The value of the UPSC is set by the PCF.
UE policy section contents (octets d+9 to k)
The UE policy section contents consist of one or several UE policy parts.
UE policy part:
UE policy part contents length (octets q to q+1)
This field contains the binary encoding of the UE policy part contents length in units of octets (NOTE 2).
UE policy part type (bits 4 to 1 of octet q+2)

0101A2XP
0110RSLPP
All other values are reserved.
Bits 8 to 5 of octet q+2 are spare and shall be coded as zero.
UE policy part contents (octets q+3 to r)
This field contains a UE policy part encoded as specified in 3GPP TS 24.526 [19] for the UE policy part type field set to "URSP" or "ANDSP", in 3GPP TS 24.588 [19C] for the UE policy part type field set to "V2XP", in 3GPP TS 24.555 [19F] for the UE policy part type field set to "ProSeP" and in 3GPP TS 24.514 [62] for the UE policy part type field set to "RSLPP" and in 3GPP TS 24.578 [61] for the UE policy part type field set to "A2XP" respectively.
NOTE 1: When the PCF is in an SNPN, the PCF shall include the PLMN ID part of the SNPN identity in the UE policy section management sublist.
NOTE 2: The UE policy part contents length indicates the length of the value part of the UE policy part field (i.e. octet q+2 to octet r).
