Abstract: Location areas and reporting centres are two classical and popular location management schemes in cellular networks. To the best of our knowledge, no performance comparison between reporting centres and location areas has been reported in literature. The paper compares the performance of the location areas scheme and the reporting centres scheme in terms of the paging and update cost. Given a set of reporting centres, the paper describes how to derive the location areas from the reporting centres, and claims that the paging cost in the derived location areas scheme is much smaller than that in the original reporting centres scheme whereas the update cost difference between two schemes is small. Simulations under various mobility models and incoming call arrival rates support the claim.

Keywords: cellular networks; location management; location areas; reporting centres; location update; performance comparison; paging costs; update costs; simulation; mobility models; call arrival rates; mobile communications.
