Mobility Management QoS Measures Evaluation for Next Generation Mobile Data Networks.

An evaluation of Quality-of-Service (QoS) measures in mobility management for interworked Next Generation Mobile Data Networks (NGMNs) is presented in this paper. The interworking framework used for the QoS analysis is a novel approach for NGMNs. This enables multiple cellular networking technologies such as the Universal Mobile Telecommunications System (UMTS) and CDMA2000 technology to interwork with Wireless Local Area Networks (WLANs) under a common platform. The proposed framework exploits the IP Multimedia Subsystem (IMS) as a universal coupling mediator for real-time session negotiation and management and Mobile IP (MIP) for IP mobility management. The latter part of the paper uses an analytical model for analyzing the QoS measures related to mobility management and uses an OPNET based model for verification. [ABSTRACT FROM AUTHOR]
