9.11.4.37 Non-3GPP delay budget

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 Non-3GPP delay budget information element is to indicate the non-3GPP delay budget for the non-3GPP network behind the UE to the network.

The Non-3GPP delay budget information element is a type 6 information element with a minimum length of 8 octets. The maximum length for the information element is 65538 octets.

The Non-3GPP delay budget information element is coded as shown in figure 9.11.4.37.1.

Number of QFIs (octet n*)The number of QFIs field is present if QFIPI is set to 1. If QFIPI is not set to 1, this field shall not be included in the non-3GPP delay budget. The number of QFIs field contains the binary coding for the number of QFIs associated with the same non-3GPP delay budget value. This field is encoded in bits 8 through 1 of octet 4 where bit 8 is he most significant and bit 1 is the least significant bit.
List of QFIs (octet (n+1)* to octet m*)The list of QFIs field is present if QFIPI is set to 1. If QFIPI is not set to 1, this field shall not be included in the non-3GPP delay budget. This field indicates QoS flow(s) associated with the same non-3GPP delay budget value. This field contains QFI values encoded as belowBits8 7 6 5 4 3 2 10 0 0 0 0 0 0 0 Reserved0 0 0 0 0 0 0 1 QFI 1 to0 0 1 1 1 1 1 1 QFI 63The other values are spare. If spare value is used, the UE shall ignore the value.
Packet filter list (octet 7 to u)The packet filter list is present if PFPI is set to 1. If not present, this field shall not be included in the non-3GPP delay budget. The encoding of the packet filter list follows the figure 9.11.4.13.4 and the table 9.11.4.13.1.
