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.<
