AnInterworking Mechanism between SCFsandProtocols intheOpenService Gateway
Ki-Sook Chung, Youngil Choi · 2006
Oneoftheimportant keyaspects ofNGNisthe Openservice gatewayprovides openAPIswhich separation ofservice control andprovision fromtheunderlying abstract networkcapabilities such as callcontrol, network. Considering theevolution ofcustomer requirements for converged services, opening up thenetworkcapabilities is esc termication multiedia messagn an inevitable. Openinterfaces suchasParlay/OSA andParlay X etcforapplication developers. Each interface iS API enablethirdpartyservice providers to developimplemented intheformof SCF (Service feature communication services without specific knowledge ofthe capability) inthegateway. underlying network. Openservice gatewayprovides openAPIs whichabstract network capabilities suchascall control, presence, terminal location, multimedia messaging, andetcforapplication developers. Eachinterface isimplemented intheformofSCF 0X (Service feature capability) inthegateway. Sinceopenservice i gateway interacts withNGN whichisbroadband convergence Oth NetworkOperator network, itshouldprocess more thanone networkprotocol.
