Mobility tracking operations in Personal Communication Services Networks (PCS)aresignal-consuming. Several strategies have been proposed in the literatureto reduce both the location update (LU) and the paging (PG) costs. In thispaper, we use a Three Location Area (TrLA) Location Tracking Algorithm. Inthe TrLA, the Mobile Terminal (MT) is located in three Location Areas (LAs)with a common perimeter between them. They form the Big Location Area (BLA).Eachtime the MT exits the BLA, and thus enters a new LA, it triggers anLU message towards the Fixed Network (FN) and updates itscaché memory. Inthis article, we evaluate the impact of the TrLA Location Tracking Algorithmin the FN and provide the Registration (RG) and Interrogation (IG) costsin order to estimate the load per MT in the FN devices. These devices arethe Home Location Register (HLR) and the Visitor Location Registers (VLRs),and they form the System DataBase (SDB).Our study is based on an analytical model of a semi-Markov process.
