9.11.3.44 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 PDU session status information element is to indicate the state of each PDU session that can be identified by a PDU session identity.
The PDU session status information element is coded as shown in figure 9.11.3.44.1 and table 9.11.3.44.1.
The PDU session status information element is a type 4 information element with minimum length of 4 octets and a maximum length of 34 octets.

| PSI(x) shall be coded as follows:PSI(0):Bit 1 of octet 3 is spare and shall be coded as zero.PSI(1) – PSI(15):0 indicates that the 5GSM state of the corresponding PDU session is PDU SESSION INACTIVE.1 indicates that the 5GSM state of the corresponding PDU session is not PDU SESSION INACTIVEAll bits in octet 5 to 34 are spare and shall be coded as zero, if the respective octet is included in the information element. |
