5.6.3.1 General
Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).
The notification procedure is used by the network:
- to request the UE, by sending the NOTIFICATION message over 3GPP access, to re-establish the user-plane resources of PDU session(s) associated with non-3GPP access over 3GPP access or to deliver 5GSM downlink signalling messages associated with non-3GPP access over 3GPP access when the UE is in 5GMM-IDLE mode over non-3GPP access and in 5GMM-CONNECTED mode over 3GPP access; or
- to request the UE, by sending the NOTIFICATION message over non-3GPP access, to re-establish user-plane resources of the PDU session(s) or to deliver downlink signalling associated with 3GPP access over 3GPP access when the UE is in 5GMM-CONNECTED mode over non-3GPP access and:
- in 5GMM-IDLE mode over 3GPP access when the UE is not in MICO mode or when the network determines the unavailability period is not activated for the UE; or
- in 5GMM-IDLE mode with suspend indication over 3GPP access when the UE is not in MICO mode or when the network determines the unavailability period is not activated for the UE.
The network shall not use the NOTIFICATION message to re-establish user-plane resources of PDU session(s) associated with non-3GPP access over 3GPP access if all the PDU sessions of the UE that are established over the 3GPP access are associated with control plane only indication. .
The network shall not use the NOTIFICATION message over non-3GPP access, if:
