An Application Server Approach for Number Portability in IMS networks

Abstract

Currently, there are many wireless networks based on different radio access technologies (RATs). Despite this, new kind of networks will be developed to complement those already existing today. As there will be no RAT able to give users full service requirements with universal coverage, the next generation wireless networks will integrate multiple technologies, working jointly on a heterogeneous way. Heterogeneous networks necessitate joint radio resource management (JRRM) mechanism to enhance better resource utilization and give users better quality of service. Joint call admission controls (JCAC) are a kind of JRRM mechanisms. In this paper, we present a JCAC approach to heterogeneous wireless network management based on reinforcement learning to treat call admission and technology selection, enhancing the network's performance. The effectiveness of this approach is assessed in terms of blocking rate results obtained by two simulation scenarios. Joint call admission control, JCAC, resource allocation, reinforcement learning, heterogeneous networks.I.

An Architectural Framework for Delivering Sip-As Multimedia Services Based on JADE/OSGI Technology

“…This section analyzes exclusively SIP approaches that have correlation with customized telecommunications services (for example, additional services, toll free phone services, Televoting, local number portability) or with the framework presented in this work. Oliveira et al [10] propose two approaches for implementing number portability service in IMS networks, tested on an AS (Application Server) according to the standards of the General Regulations of Portability. In the first approach, the AS performs the function of local number portability without call states control, routing every call originated by IMS to AS, or those based on a numeric phone context through an Initial Filter Criteria (IFC).…”
