Objective
The main objective of GEMINI is to offer existing and next-generation customized and personalized IN services in an IP based environment to meet the demands of multi-party multi-connection and multimedia calls. Achieving this goal will require the design of a modular and scalable architecture for the provisioning of IN/IP-based services and the definition of all elements of this architecture in terms of entities, protocols and interfaces. Additionally, the proposal will focus on the interworking between the IP- and the SS7- based architectures in order to deliver value-added and extended IN services (beyond the CS-2 set) in a converged environment to both PSTN and VoIP clients.
Objectives:
- To analyse and define the overall distributed system architecture, that will allow the interoperability of IN/IP services in converged voice networks, with the existing ones based on IN/PSTN networks;
- To extend the CS-2 capabilities of the IN/SS7 network for the support of VoIP users;
- To specify and develop the functionality (services, protocol layers, interfaces) for the IN/IP - IN/PSTN Signalling Gateway;
- To define and develop the Service Switching Points (SSP-IP) and the Service Control Points (SCP-IP) in the IP environment;
- To design and develop a unified approach for a Service Creation Environment;
- To resolve signalling transport issues (reliability, security) of SS7 application part messages (ISUP, TCAP) in the IP environment;
- To assess the migration of telecom operators to the new types of services and networks through representative industrial deployment and trials.
Work description:
The project is organised in six workpackages (WP) combining the necessary partners and expertise for assuring successful execution and accurate market orientation:
- Initially the Service requirements and GEMINI specifications (WP2) are determined. In this phase the supported IN services (CS-2 and extensions to the CS-2 Service set) required by the end-users are defined, and the technological framework for the system is provided;
- Based on the users' expressed requirements, the Development of the PSTN-based IN infrastructure (WP3), will design and develop the main element of the GEMINI architecture;
- The IN/SS7 Signalling Gateway, which will allow the use of the IN/PSTN infrastructure already in place. Work will also include the implementation of an extended-CS2 set of services and other details (numbering translation schemes, interfaces with existing VoIP network infrastructure);
- The Development of the IP-based IN infrastructure (WP4), aims at the development of the network entities on the IP network side. The main sub-systems developed shall include SSP-IP and the SCP-IP components termed after their SS7 SCN-analogs. Furthermore the advanced environment used for Service Creation and Management in the converged network is being developed;
- The Integration and User Trials (WP5), involve the development of a pilot network, integrating the components introduced and providing evidence on the feasibility of the project's results. The user trials shall be performed using the GEMINI platform to allow services' interworking between Partner 1's PSTN network and Partner 1 and/or Partner 6 recently deployed VoIP network;
- Finally the Market Assessment / Exploitation and Dissemination (WP6), which extends throughout the project's lifecycle, relates among others to the assessment of market status, the promotion efforts, the potential research publications and the standardization of the project's results.
