| Popis: | 96 According to the characteristic of idle mode of IEEE 802.16j, we provide a novel location management scheme. It combines with paging area based scheme and timer- based scheme. The paging area based scheme is the paging and location update in di®erent areas. The timer-based scheme is that the system paging all cells users may be in and update location period. In order to guarantee the scheme''s accuracy, we provide a rule to label the cells of IEEE 802.16j. The mobility model is also a random walk model and it can quickly get user''s location at each cell. In addition, we formulate mathematical equations and get the optimized result. We compare the mathematical analysis result with the simulation result. We get characteristics about di®erent messages arrival rate and the variable mobility probability under our scheme. |
