scope:

The scope of this Standard is the definition of the interface and message transfer protocol between a Cell Broadcast Entity (CBE) and a Cell Broadcast Center (CBC) to support text-based Cell Broadcast services.

Purpose

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

One of the main goals behind the CBE-to-CBC interface is to have a common interface from the CBE to the CBC that is independent of Cell Broadcast applications and the technologies associated with the Commercial Mobile Service Provider (CMSP) infrastructure. Any application-dependent functions are to be handled by the CBE, whereas any technology-dependent functions [e.g., Global System for Mobile communications (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE)] are to be handled by the CBC.
