Nowadays, it is known that the success of new telecommunications networks is directly related to the success of offered services that enhance their use. The arrival of the IP Multimedia Subsystem (IMS) promises helping service providers to deploy a complete array of services on real-time, customized business and consumer multimedia services over any access network. This project describes a new service plain for IMS to give support to the service development. This new service plain is a new platform, the orchestration platform, offered by the network operator to allow the easy development of new and complex services for professional and nonprofessional developers, and to provide a better time-to-market. On other hand, there is a clearly evolution of Internet applications to the web 2.0 concept based applications, which enhances the role of the user into the applications. Also, this project presents the adaption of the IMS provisioning and service enablers to the orchestration platform, and conserves the network interaction for the orchestration services with the aim of making a powerful platform and to promote the service web 2.0 concept based applications development. Finally, to see completely the platform and network functionality, the project contains also an application over the orchestration platform and also a client side application developed on .NET for Windows Operative System and Windows Mobile Operative System.
