QoS-guaranteed seamless mobile communication for realtime multimedia telephony and teleconference are strongly required across multiple wireless communication networks, such as IEEE 802.11 Wireless LAN, 802.16 Wireless MAN, and Cellular Telephone network. Each wireless network has different access mechanism and available bandwidth. IEEE 802.21 MIH (Media Independent Handover) has been developed to enable vertical handover and interoperability among heterogeneous wireless networks. IEEE P1900.4 defines how to control and manage the composite wireless network resources more efficiently.

In order to provide QoS-guaranteed seamless mobile realtime multimedia service across heterogeneous wireless networks while maximizing the network resource utilization, the available network resource should be continuously checked and arranged before the vertical handoff considering the required network resource for the multimedia service. Cognitive network management is strongly necessary for the QoS-guaranteed vertical handover while the network resource utilization is maximized.

In this seminar, the architecture of composite wireless network (CWN) defined in P1900.4, cognitive network management architecture, and detailed operational procedure in the QoS-guaranteed, seamless mobile multimedia service provisioning are studied. Firstly, it provides an overview of the architecture and operation of cognitive network management for vertical handover in composite wireless network (CWN). The distributed cognitive network management architecture for inter-AS traffic engineering for QoS-guaranteed seamless mobile multimedia service provisioning is explained.
