Architecture

A Cell Broadcast System (CBS) consists of one Cell Broadcast Centre (CBC) and one or more Cell Broadcast Entities (CBE).

A CBC is located in the network of a mobile operator and connects directly with the Base Station Controllers (BSC) for 2G support and with the Radio Network Controllers (RNC) for 3G support, bypassing the core network.

The CBEs are typically located at the Content Provider. CBEs are available in different types, from terminals to enter free format messages to applications that make up a full service.
