3GPP 24.501 v20.0.0 — the document's own text
9.11.3.13 Allowed PDU session status
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 Allowed PDU session status information element is to indicate to the network user-plane resources of PDU sessions associated with non-3GPP access that are allowed to be re-established over 3GPP access or if there is no PDU session(s) for which the UE allows the user-plane resources to be re-established over 3GPP access.
NOTE: Allowed PDU session status IE is not applicable for MA PDU session(s) in this release of specification.
The Allowed PDU session status information element is coded as shown in figure 9.11.3.13.1 and table 9.11.3.13.1.
The Allowed PDU session status is a type 4 information element with minimum length of 4 octets and maximum length of 34 octets.

| PSI(x) shall be coded as follows:PSI(0):Bit 1 octet 3 is spare and shall be coded as zero.PSI(1) – PSI(15):0 indicates that the user-plane resources of corresponding PDU session is not allowed to be re-established over 3GPP access.1 indicates that the user-plane resources of corresponding PDU session can be re-established over 3GPP access.If there is no PDU session for which the user-plane resources can be re-established over 3GPP access, all bits in PSI(1) – PSI(15) shall be coded as zero.All bits in octet 5 to 34 are spare and shall be coded as zero, if the respective octet is included in the information element. |
