A technique for inter-platform communication between functional components located on different network access platforms will be described. A method aspect of this technique comprises the step of providing a first network access platform comprising a first functional component adapted to provide and/or request a platform-based function to and/or from a second functional component located on a second network access platform. On the first network access platform an inter-platform communication application is installed that is adapted to control signalling between the first functional component and the second functional component. The inter-platform communication application is enabled to contact a first middleware function provided for accessing the second functional component. Then, a communication path is established between the first functional component and the second functional via the inter-platform communication application and the first middleware function.
