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 centrally manage the amount of interference in all cells within the coverage area and allocate resources efficiently and optimally. In this study, we propose and(More)
In parallel with terrestrial and satellite wireless networks, a new alternative based on platforms located in the stratosphere has recently introduced, known as High Altitude Platforms (HAPS). HAPS are either airships or aircraft positioned between 17 and 22.5 km above the earth surface. It has capability to deliver a wide spectrum of applications to both(More)
In near future, user equipment (UE) will operate in a multimode heterogeneous system, providing speech, data and new emerging value-added services to the wireless user. In this paper, we propose a UE geo-positioning method that harnesses on the cellular and peer-to-peer connectivity capabilities of the heterogeneous system, introducing higher accuracy in(More)
High altitude platform station (HAPS) universal mobile telecommunications system (UMTS) has the potential to be deployed together with terrestrial tower-based UMTS, with HAPS UMTS providing continuous macrocell coverage and tower-based UMTS providing selected areas of hot spot coverage. Under such a deployment scenario, inter-system handover (between HAPS(More)
