Roughly eight years have passed since the first commercial deployment of 3G mobile communication based on the WCDMA radio-access technology developed by 3GPP∗. Since then, the 3GPP radio-access technologies have gone through several steps of evolution and improvements, further boosting their capabilities in terms of the services that can be provided as well as the basic system performance. In p...

Voice over IP (VoIP) is a key driver in the evolution of voice communications, and the high transmission rate property of High Speed Packet Access (HSPA) is expected to satisfy the strict delay requirements of VoIP. Therefore, the aim of this paper is to evaluate the performance of VoIP service in HSPA network. This paper presents a mathematical model for VoIP capacity in HSPA under the constra...

In the development and commercialization phase of information technology products implemented as a system on a chip (SoC), field-programmable gate array (FPGA) based platform has been widely used as the logic function test methodology for basic or advanced features and mobile station emulator. In this situation, to define the uniform verification approach on FPGA development platform, we introd...

Abstract In this session, WHO together with the UHC2030 Technical Working Group on Health System Assessment and European Observatory Systems Policies discuss main elements of their joint approach to HSPA. The workshop intends propose a common practical framework that links descriptive health system analysis evaluation, focussing outcomes. framework's uncovering challenges bottlenecks sources va...

Pathfinding on large maps is time-consuming. Classical search algorithms such as Dijkstra’s and A* algorithms may solve difficult problems in polynomial time. However, in real-world pathfinding examples where the search space increases dramatically, these algorithms are not appropriate. Hierarchical pathfinding algorithms that provide abstract plans of future routing, such as HPA* and PRA*, hav...
