An estimate of network database transaction volume to support personal communications services

Network databases will be essential to support wide area connectivity between personal communications services (PCS) users for a variety of data management functions ranging from user mobility to communications security. The authors present a model for real-time database query and update processes associated with user mobility, registration/deregistration activity and call delivery. The mean and probability distribution of database transaction volume are then estimated both analytically and by Monte Carlo simulations. The authors´ results indicate that for PCS in a regional calling area, the real-time query rate is an order of magnitude higher than the near-term load of intelligent network databases, and in addition, a substantial amount of real-time updates is required
