| Abstract | The main target of location management is to maintain location of users while minimizing the system operation. The system process consists of location update, paging, and database consideration. The location update and paging manages the user-network interaction cost as low as possible, while the database maintains user data and manages these data transferred efficiently. In recent researches about location update and paging strategy, the objective is to reduce the cost of system operation. Database study emphasizes on the performance in transferring user data from one place to another. This thesis studies on combining velocity paging strategy and timer-based update strategy with Distributed Database comparing to the standard strategy, Location Area scheme with Centralized Database. The Velocity paging scheme estimates the paging area by the user velocity and the time span from the last registration. In timer-based update scheme, mobile terminal updates its location when the timer counter exceeds the time threshold. The performance evaluation of location update, paging, and database is achieved. In LA scheme, a good choice of location area assignment can minimize the total cost but when the users behavior change, the previous assignment cannot be considered optimal any more. For VP scheme with timer-based update scheme, a good choice of time threshold can minimize the total cost and the time threshold can be adapted according to user behavior to minimize the cost. Meanwhile the Distributed database can manage the data transferred more efficiently than the Centralized Database. |
