Interoperability in a multiple-provider telecommunications environment

The telecommunications market is becoming increasingly complex, with a rapidly increasing number of providers offering a range of new service types. It is essential that there is interoperability between different providers so that services can be delivered in a managed way, to the benefit of both providers and consumers. This paper describes prototype implementation experiments carried out in a European collaborative project (EURESCOM P715), validating and assessing the utility of TINA (Telecommunications information Networking Architecture) Reference Point specifications for achieving service-level interoperability in a multiple-provider environment.
