Strategy of Location Management Based on Dynamic Probability for PCS Networks
Introduces a dynamic probability-based location management method,which is suitable for mobile objects moving with any mobility patterns.It uses a novel location update strategy that bases on direction and predictive distance respectively in different cases.It also uses a dynamic paging strategy bases on the resident probabilities and the moving direction probabilities of mobile units.An analytical model is promoted to decide the location update and paging strategy.Given the respective costs for location update and terminal paging,the average total location update and terminal paging cost is determined.The experiment results shows that the proposed location management strategy could get much smaller cost of paging than that of ring-by-ring strategy.
