scope:

The scope of this Standard is the definition of the interface and message transfer protocol between a Commercial Mobile Service Provider (CMSP) Gateway and a Cell Broadcast Center (CBC) to support Wireless Emergency Alert (WEA) services.

Purpose

The purpose of this Standard is to define a message transfer protocol on the interface between the CMSP Gateway and CBC; to identify the requirements on the CMSP Gateway and CBC to support the interface; and to identify requirements to support assumptions made in other specifications, such as the 3GPP specifications (e.g., 3GPP TS 23.041 [Ref 1]).

In the 5G System the CBC is called Cell Broadcast Center Function (CBCF). The remainder of the present standard uses the term CBC, but it is to be understood that the term CBC also applies to the CBCF.
