Abstract
A mobile user location management mechanism is introduced that incorporates a distance based location update scheme and a paging mechanism that satisfies predefined delay requirements. An analytical model is developed which captures the mobility and call arrival pattern of a terminal. Given the respective costs for location update and terminal paging, the average total location update and terminal paging cost is determined. An iterative algorithm is then used to determine the optimal location update threshold distance that results in the minimum cost. Analytical results are also obtained to demonstrate the relative cost incurred by the proposed mechanism under various delay requirements.

MobiDe '03: Proceedings of the 3rd ACM international workshop on Data engineering for wireless and mobile accessA low-cost, two-step location update/paging scheme in a macrocell/microcell network is proposed and investigated. To reduce operating cost, the location update is operated only in the macrocell tier. A callee will be paged in the macrocell tier first. ...
