Abstract: A system and method of creating subscriber services in an Internet Protocol (IP)-based telecommunications network. A service creation architecture includes a Service Component Creator (SCC) that creates service proxy objects, and posts them on a Lookup Service (LUS). The LUS is accessible through the Internet by Enterprise Service Creators (ESCs). The ESCs download the posted service proxy objects from the LUS, and customize the downloaded objects to create customized services for enterprise users. The ESCs upload the customized service proxy objects to an Enterprise LUS, and the, Enterprise LUS downloads the customized service proxy objects to a Service Management Unit (SMU) serving the end user. A gatekeeper serving the end users utilizes the service proxy code downloaded to the SMU to determine the location of a Service Implementation Repository (SIR) that stores actual service code for implementing the customized service.

Abstract: A method and apparatus for automatically locating sources of semantic error in a multi-agent system based on setup connection tree information, and informing the appropriate agents so that they can avoid using the faulty resources in the future. The setup connection tree model is established based on patterns of agent actions for expressing the logical relationship between available resources in the disjunctive normal form (d.n.f.). A table is used to record different sets of resources for use in the resource selection process. Thus, faulty resources can be located by means of induction. A global database is also maintained for updating information on semantic errors in the system.
