PCS망에서의 위치관리 방법에 관한 연구 = A Study on the Location Management Mechanism in the PCS Network

다국어 초록 (Multilingual Abstract)

To support a lot of subscriber and multimedia services in the PCS network, wireless network is required to have higher bandwith utilization. And the challenge of supporting rapidly growing numbers of mobile susbscribers is being met through increasingly smaller radio cells. This, however, results in increased signalling for location management procedures, which reduces the bandwith available for user traffic.
Location area in current systems is consist of static and arbitrarily-definded collections of cells, which do not take into account individual subscriber mobility patterns, either in space or time. A location management algorithm is proposed which uses the mobility history of individual subscriber to dynamically create individualized location areas, based on previous movements from cell to cell. The average duration spent in each visited cell is also maintained and is used to define paging which are most likely to contain the subscriber.
And we propose a location management scheme which operates adaptively according to the speed of mobile station. It could be seen from analysis results that the signalling traffic for the registration and paging could be significantly reduced by using the proposed location management scheme.
