4G mobile communication network will encompass various access technologies to provide a heterogeneous environment with IP as the network protocol. Within the heterogeneity framework, there is a need to create mobility standards to support seamless roaming among the various access technologies and the adaptive provisioning for multimedia applications. In this paper, an analysis of combining Fast Mobile IPv6 and Session Initiation Protocol (SIP) to handle real-time mobility is proposed. Advanced resource management techniques to support Quality of Service (QoS) are also considered for realtime mobility within the Next Generation network (NGN) platform. The techniques may use a QoS Manager to allow an end-to-end coordination and provisioning of Quality of Service. The function of the QoS Manager also includes dynamic allocation of resources during handover.
Abstract-The next generation wireless network needs to provide seamless roaming among various access technologies in a heterogeneous environment. In allowing users to access any system at anytime and anywhere, the performance of mobilityenabled protocols is important. While Mobile IPv6 is generally used to support macro-mobility, integrating Mobile IPv6 with Session Initiation Protocol (SIP) to support IP traffic will lead to improved mobility performance. Advanced resource management techniques will ensure Quality of Service (QoS) during real-time mobility within the Next Generation Network (NGN) platform. The techniques may use a QoS Manager to allow end-to-end coordination and adaptation of Quality of Service. The function of the QoS Manager also includes dynamic allocation of resources during handover.Heterogeneous networks raise many challenges in security. A security entity can be configured within the QoS Manager to allow authentication and to maintain trust relationships in order to minimize threats during system handover. The next generation network needs to meet the above requirements of mobility, QoS, and security.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
