The 3rd Generation Partnership Project (3GPP) has proposed the IP Multimedia Subsystem (IMS) as a key element in the nextgeneration network (NGN) converged architecture supporting multimedia services. Extending the IMS towards provisioning support for location based services (LBS) will enable enhanced services and offer new revenues to the system. However, conveying location information in the ...

In the field of telecommunication, to deliver high quality and low cost multimedia services to users is indeed a milestone. Next Generation Network (NGN) is an IP network which facilitates researcher to achieve this milestone. IP Multimedia Sub-system (IMS) makes possible to deliver IP multimedia services to users. IMS uses Session Initiation Protocol (SIP) as a signalling protocol. Since IMS i...

In this paper we will explore security threats and attacks possibility and security solution for Application Server of IP Multimedia Subsystem(IMS-AS). The SIP Application Server is an important entity of IP Multimedia Subsystem (IMS) because applications providing value added services are deployed on the Application Server. The SIP Application Server is triggered by Serving Call State Control ...

This chapter aims to provide a critical evaluation of security issues and potential solutions related to the use of free and open enterprise resource planning (FOS ERP) systems in highly dynamic and heterogeneous next generation networks (NGN). The authors first present a brief state of the art with respect to technologies, features and applicability of the existing security solutions for ERP s...

Rapid service creation stemmed from the convergence of fixed line and mobile telephony with the Internet has made user acceptance to be a crucial factor for the success of the telecommunication business. Telecommunications research, therefore, can no longer be considered only from the pure engineering perspective. Within this paper, we present the concept of service quality for future NGN netwo...

Next Generation Network has drawn great attention by the researchers and telecommunication industries as the future generation in the communication technologies and services. The interest covers all aspects on NGN from the global standards, architecture and services. The management of services provided in the NGN environment has posed great challenges due to the heterogeneity of the service pro...
