Abstract: Broadband and narrowband convergence trunking network with a uniform core network architecture, provides more reliable service using overlapping coverage in mission critical communication. Multi- mode handset with integrated design could offer consistent user experience regardless of communication mechanism. Application innovation combined with low complexity multi-mode handset can greatly facilitate the development of broadband and narrowband convergence trunking networks. By tapping the technical advantages of wide and narrowband networks respectively provides users more powerful business applicationcapabilities.

Key words: broadband and narrowband convergence, trunking network, multi- mode handset, channel reliabilityconfidence, modeswitch
