Abstract

A Commercial Mobile Alert System (CMAS) providing redundant cell broadcast centers (CBC). Multiple CBCs are interfaced to any given base station controller (BSC) or radio network controller (RNC) to provide geo-redundancy and high availability so that the failure of one CBC or a cluster of CBCs at one site will not cause service interruption for the area controlled by the associated BSC or RNC or for the entire service area in the public land mobile network (PLMN) network. The BSC or RNC interfaces to multiple CBCs at multiple sites without changes to the otherwise conventionally existing BSC/RNC, 3GPP 23.041 standard architecture.
