A method of enabling a communication between functional components (120, 130; 210, 212') located on different network access platforms (106, 112; 204, 222, 222'), wherein the different network access platforms (106, 112; 204, 222, 222') are adapted to provide network access in accordance with different network access technologies to a device, the method comprising the steps of: - providing a first network access platform (112; 222; 222') comprising a first interface and a first functional component (120; 212'; 212") adapted to provide and/or request a platform-based function to and/or from a second functional component (130; 210) located on a second network access platform (106; 204), wherein the first network access platform and the second network access platform are co-located within the device; - installing on the first network access platform (112; 222; 222') an inter-platform communication application (122; 224) adapted to control signalling between the first functional component (120; 212'; 212") and the second functional component (130; 210); - enabling the inter-platform communication application (122; 224) to contact a first middleware function (126; 214; 214') provided for accessing the second functional component (130; 210) by coupling the first interface directly to a second interface of the second network access platform (106; 204), so as to enable a platform-to-platform communication between the network access platforms on a level of platform tiers including the first and second functional components (120, 130; 212', 210; 212", 210) communicating with each other, which level is below application tiers (110, 116) including the inter-platform communication application (122; 224) and below middleware tiers (108, 114) including the first middleware function (126; 214; 214'); and - establishing a communication path (134; 280) between the first functional component (120; 212'; 212") on the first network access platform and the second functional component (130; 210) on the second network access platform via the inter-platform communication application (122; 224) and the first middleware function (126; 214; 214') and through the coupled first and second interfaces (124, 128), the communication path (134; 280) starting within one of the platform tiers and ending within another one of the platform tiers. - providing a first network access platform (112; 222; 222') comprising a first interface and a first functional component (120; 212'; 212") adapted to provide and/or request a platform-based function to and/or from a second functional component (130; 210) located on a second network access platform (106; 204), wherein the first network access platform and the second network access platform are co-located within the device; - installing on the first network access platform (112; 222; 222') an inter-platform communication application (122; 224) adapted to control signalling between the first functional component (120; 212'; 212") and the second functional component (130; 210); - enabling the inter-platform communication application (122; 224) to contact a first middleware function (126; 214; 214') provided for accessing the second functional component (130; 210) by coupling the first interface directly to a second interface of the second network access platform (106; 204), so as to enable a platform-to-platform communication between the network access platforms on a level of platform tiers including the first and second functional components (120, 130; 212', 210; 212", 210) communicating with each other, which level is below application tiers (110, 116) including the inter-platform communication application (122; 224) and below middleware tiers (108, 114) including the first middleware function (126; 214; 214'); and - establishing a communication path (134; 280) between the first functional component (120; 212'; 212") on the first network access platform and the second functional component (130; 210) on the second network access platform via the inter-platform communication application (122; 224) and the first middleware function (126; 214; 214') and through the coupled first and second interfaces (124, 128), the communication path (134; 280) starting within one of the platform tiers and ending within another one of the platform tiers.
