In this work we have addressed the issue of inherent trade-off between location update cost and paging cost for proper location area (LA) planning and have attempted to find out an optimal LA size such that the total cost comprising of location update and paging can be minimized. We have formulated a constrained cost optimization problem under the known patterns of call arrival and terminal mobility. The present work is divided into two parts. First, we have tried to validate the model itself; next we have proposed an algorithm based on simulated annealing technique as a solution methodology for the hard constrained optimization problem.
