3GPP 24.501 v20.0.0 — the document's own text
6.2.9.3 ProSeP
Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).
The ProSeP requires interaction between upper layers and the 5GSM entities in the UE acting as a 5G ProSe layer-3 UE-to-network relay UE (see 3GPP TS 24.554 [19E] for further details). The upper layers may request the 5GSM entity:
- to establish a PDU session indicating one or more PDU session attributes; or
- to release the existing PDU session; or
- to establish a PDU session indicating one or more PDU session attributes, and to release the existing PDU session.
Each of the 5GSM entities in the UE acting as a 5G ProSe layer-3 UE-to-network relay UE shall indicate attributes (e.g. PDU session identity, SSC mode, S-NSSAI, DNN, PDU session type, access type, PDU address) of the newly established PDU session to the upper layers. If the PDU session is released, the 5GSM entity handling the PDU session shall inform the PDU session identity of the released PDU session to the upper layers.
