F.2.1 Procedures at the UE
The UE may support any of the procedures of clause F.2.1.
F.2.1.2 Application specific Congestion control for Data Communication (ACDC) procedure
The following information is provided to the non-access stratum layer:
– MO-SMSoIP-attempt-started; and
Upon request from the user to submit an originating SM over IP as described in clause 5.3.1 and no other originating SM over IP as described in clause 5.3.1 exists, the UE sends the MO-SMSoIP-attempt-started indication to the non-access stratum and continue with SM over IP submission as described in clause 5.3.1.
When an originating SM over IP submission is completed and no other originating SM over IP as described in clause 5.3.1 exists, the UE sends the MO-SMSoIP-attempt-ended indication to the non-access stratum.
NOTE: If the UE supports other 3GPP specific mechanisms for communicating with the non-access stratum protocol implementation, e.g. DHCP discovery via PCO, then the UE is expected to support the transfer of information elements needed for the application specific congestion control for data communication enforcement.
