Trunked Radio Traffic In Overhaul Interval

Radio trunked network in South Pars Gas Complex (SPGC) is a basement infrastructure for operators to communicate in industrial site and in overhaul period time. Reliability and stability in radio communication is so critical too. Its network is affecting on overhaul period time, quality in human resources communication in industrial site, and non satisfaction in operators psychologically. So the author decided to study and analyzes the needs and abilities of the system more scientific and presents some offers to more efficiency.There are various parameters affecting in network operating. Occupancy percentage beside the banning laws, difference in frequency band used in each country, international law breaching, depreciated equipments and non effective communication basements in refinery are main reason leads network to non appropriate working.In this paper by investigating some Radio Trunk s errors in one of refineries we are comparing some of parameters in overhaul period and normal working period. And existent traffic is debated upon that. Successful registration, called busy, and percentage of occupancy are main debated parameters. From more than 200 parameters, three more effective ones; calling barred, called busy and control channel time out are such interesting issues whom are studied more carefully. They illustrate a few losses in refinery radio network. Author will proposes some offer to improvement the network in continue.
