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

The present document describes the Cell Broadcast short message service (CBS) for GSM and UMTS.

For GSM it defines the primitives over the Cell Broadcast Centre – Base Station System (CBC-BSS) interface and the message formats over the Base Station System – Mobile Station (BSS-MS) interface for Teleservice 23 as specified in 3GPP TS 22.003 [2].

For UMTS it defines the interface requirements for the Cell Broadcast Centre – UMTS Radio Network System (RNS) interface and the radio interface requirements for UMTS Radio Acces Networks to support CBS as specified in 3GPP TS 22.003 [2].

The present document also describes the Public Warning System (PWS) for GSM, UMTS, E-UTRAN, and NG‑RAN, see 3GPP TS 22.268 [28].
