7 BTS Functionality

23.0413GPPRelease 18Technical realization of Cell Broadcast Service (CBS)TS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

Only GSM [The BTS is responsible for conveying CBS information received via SMS BROADCAST REQUEST or SMS BROADCAST COMMAND messages over the radio path to the MS.

– optionally generating CBCH Load Indication messages, indicating an underflow or overflow situation on the CBCH (see 3GPP TS 48.058 [11]).]
