Intelligent location tracking strategy with delay bounds in PCS

Location tracking (paging) and location update (registration) are the two fundamental operations in locating a mobile terminal in cellular mobile networks. In a location tracking process, the network system initiates a search process to find the mobile terminal to deliver an incoming call. A novel location tracking strategy is proposed based on location probability models that aims to reduce the signalling cost involved in location tracking (paging) under delay bounds. Numerical results demonstrate that this paging strategy performs better than other methods for both uniform and non-uniform location probability distributions.
