Personalised IMS client widget

Current IMS development follows the path of improving the IMS clients and client frameworks. This paper points out the shortcomings of this path for deployment in a mobile-fixed convergent multi-access IMS environment. Instead of continuing the development on IMS client frameworks, an alternative path forward using IMS client widgets is proposed as a novel concept. It involves a thin-client solution where most of the IMS features are implemented in the network. The IMS client widget solution allows for open development of flexible, customizable and personalized IMS clients, which is totally lacking with current technology and solutions. Finally, a prototype implementation of the IMS widget concept is presented.
