Service authoring for third-party programmable, service-mediation-enabled feature servers in the multiservice core

The convergence of voice and data on the multiservice core allows virtually anyone to create communications services and offer them through a Web page over public networks. Session initiation protocol (SIP) phone users may la unch new services in SIP messages. The traditional domain of service creati on by the service provider for voice traffic networks is opening up to thir d parties. This creates a host of challenges for service creation tool sets to support this new paradigm of service authoring. This paper presents the se challenges and remedies as addressed by a third-party programmable, serv ice-mediation-enabled feature server. It provides a third-party programmabl e service authoring and service logic execution environment, which supports the deployment of innovative multiservice features while resolving feature interactions and integration into existing operations, administration, mai ntenance, and provisioning (OAM&P) elements. It leverages the Java* Telepho ny API (JTAPI)-based Lucent Technologies Full Circle(TM) application progra mming interfaces (APIs), Java APIs for Integrated Networks (JAIN*)/Parlay, SIP and Extensible Markup Language (XML) to maximize flexibility in integra ting new services across multiple servers in the packet network.
