Derivation of Moving Distance Distribution to Enhance Sequential Paging in Distance-Based Mobility Management for PCS Networks

The total signaling cost of distance-based location management scheme, which is the lowest among dynamic location management schemes for PCS networks, can be further reduced by a sequential paging strategy that pages first the cells in which the mobile is most likely located. To enable this strategy, we derive the probability distribution of a mobile's moving distances between the last location update and the next call arrival. An efficient and effective sequential paging scheme is presented, which guarantees that a mobile can be located during the first paging step with a probability equal to or better than a predefined value. The features of the proposed model include flexible cell topologies, general cell residence time, and full use of mobile's moving pattern
