1 Scope
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].
1.1 References
The following documents contain provisions which, through reference in this text, constitute provisions of the present
document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or
non-specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including
a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same
Release as the present document.
