The paper shows our experience in developing a trunking radiotelephone network information system using object oriented technologies. The developed information system has the network management responsibility and it offers a complete set of utilities to the network operator to facilitate its work. It has been necessary to balance requirements from the management point of view (real time interaction, statistics, etc.), requirements from the technical connection with the network (different technologies, buffering problems, etc.), and extra requirements imposed by the client (remote management option, easy to platform migration, etc.). Representation techniques based on object meta knowledge have been used as a powerful tool to provide a flexible and easy to extend mechanism to cover application design and implementation phases. The adopted architecture and the main components and their orchestration are described. The paper includes learned experiences, development criteria, problems and choices of commercial products.
