Interworking of Networks

This work area investigates the interworking of networks to provide delivery of a wide range of services in a spectrally efficient and secure & reliable manner. The services envisaged range from point-to-point to multicast and all the way to broadcast and even interactive broadcasting services; a range that has never been before offered to a mobile user through one network and one type of terminal and one subscription.

Interworking implies the co-operation and assistance of network functionality, rather than duplication of networks.

Spectral Efficiency aims at choosing the most appropriate radio access delivery mechanisms.

Secure & reliable implies achieving a more stable quality of service, higher service availability and optimum system capacity through appropriate use of network services and capabilities.

Some of the research problems being addressed are:

• criteria for selection of appropriate delivery mode: unicast, multicast or broadcast

• criteria for selection of appropriate radio access technology for service delivery

• vertical handover between different sub-networks

• simultaneous use of sub-networks for interactive services

• load balancing criteria and algorithms

• end-to-end homogenous network security layer for access to network and to service
