Concept for universal access and connectivity in mobile radionetworks

摘要

Mobile communications is characterized by a fast growing number ofusers and an increasingly heterogeneous data traffic due to emergingmultimedia packet services. Likewise, users desire more mobilitysupport, thus demanding permanent availability at any place and anyspeed. The conventional answer to this problem is building new wirelessstandards. But these standards require totally new hardware, userscannot use their old terminals, and no wireless communication amongnetworks is possible which considerably constrains the availabilitydemand. Instead, we propose a unified way for basic network access andconnectivity maintenance. It is embodied by a perpetually availablesignalling channel-the network access and connectivity channel (NACCH)and a common functionality trunk, shared by several networks. With thisconcept, networks can communicate and, hence, form a mega-network whereusers have universal access and roaming support
