Abstract
As the rapid development of mobile broadband access network technologies in recent years, 802.11 Wi-Fi, GPRS and 3G access networks have been widely used. Users have the characteristic of mobility in these wireless heterogeneous networks. As users are roaming, How to report rapidly the current location of users to network management center, so that the pagers are able to obtain the right user location for establishing communication, has become an important issue. we focus on the architecture and policies of location management for wireless heterogeneous networks. we propose the Geographical Location Registration (GLR) mechanism for location updating and paging, where the location information in wireless heterogeneous networks is maintained to rapidly page other users and to reduce the overall cost. Compared to traditional mechanisms, the proposed GLR mechanism is capable of improving the paging cost by 79%. Besides, as the moving speed of users increases, the paging cost will not increase substantially.
