—Current literature provides many practical tools or theoretical methods to plan and dimension GSM or UMTS radio networks but overlooks the algorithms of network plan and dimensioning for core networks. This paper introduces an algorithm for traffic and throughput dimensioning for UMTS core network. A case study is provided to verify the algorithms created(More)
The past few years have seen mobile operators transition to next-generation mobile networks; specifically from third-generation networks (3G) to long term evolution (LTE). This paper first describes the basic architecture and topology of UMTS R4 core network and introduces two options in network planning: flat structure or layered structure. This paper(More)
Mobile packet services are penetrating mobile markets rapidly. The mobile industry relies heavily on data services to replace the traditional voice services with the evolution of the wireless technology and market. Designing a reliable packet service network is critical to the mobile operators' ability to maintain their core competence in data service(More)
Mobile operators currently prefer optimizing their radio networks via re-homing or cutting over the cell sites in 2G or 3G networks. The core network, as the parental part of radio network, is inevitably impacted by the re-homing in radio domain. This paper introduces the cell site re-homing in radio network and analyzes its impact on the performance of(More)
