Abstract: Making the decision to migrate a user or service from a legacy network to a next generation network (NGN) requires thorough analysis. Despite the will and a clear necessity of telecom operators and service providers (SP) worldwide, many are still struggling with the migration process even after nearly five years and this can be attributed largely to the mentioned analysis aspect. New service delivery platforms (SDP) have necessitated the need to modernize or in some cases rebuild completely new operations support systems/business support systems (OSS/BSS). Mistakes have also been made in choosing an appropriate strategy for migration due to miscalculation in several key areas prior to migrating. Based on a task of moving users and services from legacy networks to IP multimedia subsystem (IMS) as well as inside the IMS, the current paper addresses the issue of making a solid migration decision, based on facts and proper analysis, concentrating mainly on the technical side of it.

Abstract: There are five different Quality of Service (QoS) classes defined by the IEEE 802.16e-2005: UGS, ertPS, rtPS, nrtPS and BE. It is well known that BE provides the lowest level of quality compared all other classes. In this paper, we investigate the performance of rtPS and BE QoS classes in an emergency and natural disaster scenario. We use the OPNET modeler for simulation purposes in order to evaluate rtPS and BE performance with particular focus on video conferencing/streaming and web browsing applications. It is possible that during a disaster BE is the only available service. Simulation results revealed that in certain situations, a user with BE QoS could provide higher throughput compared to the rtPS case. Consequently, we also evaluate the video conferencing/streaming application for the BE QoS case. Simulation results show that for a defined maximum number of users in the network and a certain combination of users that are allocated a QoS and a selected application e.g., web brows
