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 CBE to CBC interface is to have a common interface from CBE to CBC that is independent of Cell Broadcast applications and the technologies associated with the CMSP infrastructure. Any application-dependent functions are to be handled by the CBE, whereas any technology-dependent functions (e.g., GSM, UMTS, LTE) are to be handled by the CBC.

Application

This specification is applicable to a CBE interfacing to a CBC. This specification is independent of the application supported by the Cell Broadcast Service, and is intended to support any text-based application over the Cell Broadcast Service.
