The present document specifies the procedures and the SBc Application Part (SBc-AP) messages used on the SBc-AP interface between the Mobility Management Entity (MME) and the Cell Broadcast Centre (CBC), and between the Public Warning System - Inter Working Function (PWS-IWF) and the CBC.
The present document supports the following functions:
- Warning Message Transmission function in the EPS,
- Warning Message Transmission function in the 5GS via the PWS-IWF (see 3GPP TS 23.041 [14]).
NOTE: The SBc-AP interface is a logical interface between the MME and the CBC and also between the PWS-IWF and the CBC, when connected to 5GC. The PWS-IWF may not be always explicitly mentioned in the remainder of the present document.
