Abstract

A method of mediation of traffic across a particular interface between the Advanced Intelligent Network operated by a local exchange carrier and an outside service provider is disclosed. The particular interface is defined between an application by a non-local exchange carrier service provider for some form of enhanced telephone service requiring use of the Advanced Intelligent Network and a shared execution environment interpreter on the other side of the interface. Mediation is conducted by the shared execution interpreter that is run on a local exchange carrier operated service control point. The shared execution interpreter enforces sufficient rules so that the local exchange carrier does not require knowledge of the details of implementation of the service provider's application. The method defines a unique transaction identifier that is defined and known on the local exchange carrier side of the interface. A table is created carrying the unique transaction identifiers with service process identifiers generated by various service provider applications. The shared execution environment interpreter can pass messages and instructions across the interface to the service provider's application that only reference the application's internally generated service process identifier. Mediation rules include testing of tables to determine whether a directory number referenced in a message request from a service provider application is a customer of the service provider, whether trunk group routing requests are valid for the service providers and whether any access to, or particular levels of access to, certain network elements are authorized for the service provide requesting same.
