Abstract

One of the unique characteristics of high altitude platform station (HAPS) Universal Mobile Telecommunications System (UMTS) is that all base stations are collocated. This enables the HAPS to manage centrally the amount of interference in all cells within the coverage area and allocate resources efficiently and optimally. We propose and analyze two centralized total received power based call admission control (CAC) schemes for HAPS UMTS. Simulation results show that the proposed centralized CAC schemes can achieve better grades of service than the distributed global CAC scheme where CAC is managed independently at individual base stations.
