with different

By comparing user’s location management cost with different MT’s mobility, it shows that the dynamic location area scheme is more suitable for user; we also compute the cheap wedding gown dresses size of location area for two types of specific velocity.In chapter 3, the paging schemes of the LEO satellite mobile communication system have been cheap evening dresses studied. Combine with the modified user movement model, a paging strategy is presented based on the dynamic location area. It can reduce the page cost with delay constrain for high speed MT and improve the system performance.In chapter 4, the schemes on routing algorithm with inter-satellite links for custom made prom dresses satellite communication system are introduced and the 12hot cheap prom dresses Delay Constrained Least Cost Algorithm is proposed. The simulation results indicate that the sell discount wedding dresses parameters such as original call block probability, handover failure plus size wedding dresses probability are compared and some valuable results have been obtained. At last, the priority of the new strategy is analyzed.In chapter 5, the dissertation is summarized and point out the future work which need to have detail research.
