OSA ParlayX Gateway architecture for 3rdParty operators participation in next generation networks

In this paper a practical architecture for creation of OSA ParlayX Gateway in service layer of an integrated networks, according to IMS architecture will be presented. OSA ParlayX Gateway is a suitable platform for third party operators participation to provide integrated services in NGN. Third parties without any knowledge of network technologies, by using standard ParlayX APIs on top of Web Services platform which provided by network operators on OSA ParlayX Gateway node, can create new services. In this paper a layered software architecture using. Net framework for performing ParlayX transactions on network sessions (using SIP protocol) will be presented. This architecture provides faster implementation of services for third parties and high scalability of network.
