System Architecture

Cell broadcast system

A Cell Broadcast System consists of one Cell Broadcast Centre (CBC), located in the network of a mobile operator and one or more Cell Broadcast Entities (CBE), typically based at the Content Provider’s premises.

CBEs are available in different types and can be provided as either a simple terminal or as a full service application. Whichever set-up the content provider chooses, the complexity of the mobile network service remains hidden by the CBC, making the Cell Broadcast service simple to use.

Through the CBE, content providers simply create a message and select the location or locations they require the message to be sent to, using an intuitive user interface. The message is then sent to the CBC, which maps the target area to the mobile network cells.

Subsequently the CBC sends the message to the required radio access network elements, which manage the broadcast of the message in the targeted cells.

System architecture

The CBC is connected to the Base Station Controller (BSC), Radio Network Controller (RNC) or to the MSC, depending on which network standard the operator is using. These devices have the responsibility of forwarding on messages from the CBC to the base stations selected by the content provider. one2many has the most extensive BSC, RNC, MME, MSC and GAN driver library in the market, ensuring that it can integrate Cell Broadcast at any operator on any network standard.
