The specification of the Telecommunications Information Networking Architecture (TINA) has reached a stable state. TINA defines a novel and attractive way of building telecom applications. However, TINA on its own is unlikely to achieve wide market acceptance as, to a great extent, it neglects the existing telecom infrastructure. To take full advantage of the TINA Service Architecture it is necessary to find an effective way of reusing existing and emerging network capabilities. To this end, the Intelligent Networks (IN) platform can provide a well defined, high level interface to the existing fixed and mobile networks. The ACTS Project TOSCA proposes a novel approach that facilitates rapid service creation from object-oriented software frameworks [1,2]. The applicability of the 1 TOSCA TINA Open Service Creation Architecture is the ACTS project AC237. The TOSCA Consortium includes the following partners: Teltec DCU and IONA Technologies Ltd. from Ireland, BT Plc, Ericsson Ltd. and University of Strathclyde from UK, GMD Fokus from Germany, Telelogic AB and Lund Institute of Technology from Sweden, and CSELT from Italy. TOSCA approach for TINA-based multiparty multimedia services has been proven through a number of industry-scale trials involving leading European network operators. Additionally, TOSCA has verified the proposed service creation approach in a heterogeneous TINA/IN platform. Since no TINA/IN products were commercially available, the project developed a simulated model that combines the Access and Service Sessions of TINA with the connection control of IN. The scenario considered by TOSCA assumes that the service logic is invoked and executed in the TINA domain whereas IN is used mainly for establishing the speech/video connections between the participants of a service session. The role of IN is thus reduced to a high-level interface to a switched network. This scenario is of great importance for Internet-initiated telephony services such as Click-to-Dial as well as for multiparty services such as video conference type services run over B-ISDN. To create a simulated TINA/IN platform, TOSCA re-used the TINA Access and Service Session framework created by the project itself [3] and integrated it with the executable model of an IN CS2 infrastructure provided by the INAP Wrapper application [4]. Both models are designed in SDL and use Java to implement the user interfaces. Using these two languages as well as the Telelogic Tau toolset enabled the quick and effective integration of the models. The simulated TINA Service Session components USM and SSM communicate with a simulated IN SCP via a TINA/IN Gateway. This gateway processes the high-level TINA communication session messages and maps them to Parlay [5] operations. The required subset of the Parlay interface is implemented in the SCF of the IN model. Also specified in SDL, the gateway was integrated with the TINA and IN SDL models. The paper briefly outlines the principles of the fram

This article consists of a collection of slides from the author's PowerPoint conference presentation. The paper argues that the diversity of services and networks, demands a fresh approach to service creation. The authors argue that the Application Programming Interface (API) approach promises to meet many of the demands of service creation in the new environment. Formalising at the level of the API in service creation allows the underlying control structures the flexibility to be ahnost completely proprietary in nature. However it will be argued that the API approach demands new additional structures to make the model commercially viable. This paper examines the requirements of the API server and introduces the notion of an API state-machine. An API server allows third party software providers or end users access to control resources without regard to how the offered services are to be implemented. It must therefore provide the flexibility of service creation with the restriction placed by policing functions to protect against misuse of code or malicious intent The server must also provide access to support infrastructures such as billing systems and management systems. In addition it also needs to be capable of fme grained process control. Hence, the aims of the state machine are complex. The paper describes work being done at UCL in defining a state machine, similar in many respects to that of the Basic Call State Model and the Call Party Handling model but for the API server case. The state machine aims to mask the service on offer from the external requests. It also aims to reduce the interfaces between service providers to a simple state machine view that seeks to eliminates problems such as deadlock or integrity violations between complex multiple service provider interactions. The paper also examines the relationship between API approaches and the TINA framework. It argues that TINA evolution can be pushed forward by an intermediate API stage in development
