Public warning is the Public Warning Platform. leading and proven use case for cell broadcast. ■ Cell Broadcast Center (CBC). A CBC a A Cell Broadcast System consists of (redundant) network element in the mobile core network Cell Broadcast Centers and one or more Cell that sends the cell broadcast messages.

The CBC manages the aware application maintains all relevant broadcasting of those messages to the RAN. information on the radio cell location (Public Land Mobile Network [PLMN] data set) ■ CAP/CMSP Gateway. Depending on which standard is prevalent, a CAP/CMSP gateway may be required. For instance, the North American CMAS standard uses the C-interface. As a CBE, this application translates C-interface or Common Application Protocol (CAP) to connect to the CBC. In this case using one2many’s XML interface.

All the components can be enabled and integrated when required. They utilize one2many common infrastructure and OSS elements. HIGH LEVEL OVERVIEW OF TWO SCENARIOS WITH ONE2MANY‘S CELL BROADCAST CENTER

It’s not just Governments who benefit from the PWP. From an MNO perspective, the PWP enables them to create their own alerts for testing purposes.
