| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 93 === The proposed approach is to reduce the location update (LU) attempts in wireless networks by the prediction of idle movement of people. As we know there are active movement and idle movement of people recorded in the hardware of wireless networks. Active movement is recorded by cell level, but idle movement is recorded by Mobile Switching Center (MSC)/ Visitor Location Register (VLR) level. Thus there is no relationship between them. The proposed approach creates the relationship between them to generate the formula of idle movement of each cell. It uses the Mobile Originating Call (MOC), Mobile Terminated Call (MTC), and Handover (HO) form the active movement. Meanwhile it takes the LU attempts from idle movement into account. With the active movement information, we can get the directional idle movement of people of each cell on its corresponding direction. From the above information, we can get the contribution to the LU attempt for the MOCs, MTCs, and HO respectively. By the contribution, we can get the coefficients of the MOCs, MTCs, and HO. Applying the coefficients to each cell in the wireless networks, and we can get the idle movement of each cell. Since we get the idle movement of people of each cell, we can use it to find out the cells with relatively low idle movement. The best borders are set on those cells because of the relatively low idle movement. Thus the LU attempts are reduced to the minimum value. This can bring the benefits to hardware of wireless networks and free up more resource to work on the necessary services.
