Abstract: A novel Communications Management System architecture (CMS) supports asset, frequency and key management functions in a multi-unit, multi-network communications system and automates the planning required for effectively carrying out tactical communications in such an environment. CMS matches the detailed frequency and key distribution required for radio networks supporting such an operation, and consolidates all of the information required to operate such a radio system into a single database. The CMS architecture provides a flexibility to allow for specialized key and frequency assignment generation, net communications planning, distribution planning of communication equipment, deployment planning and asset planning and generation of Communications Information (CI). The architecture provides an integrated approach that enables such communication planning/management functions to be tied together into a single software program to assure verification of data and eliminate duplication of effort.
