A method of and a network function arranged for enabling data exchange between a first communication network having first data communication capabilities, such as a 5G network, and a second communication network, such as a TSN, having second data communication capabilities different from the first data communication capabilities. Communication attributes of corresponding first and second data communication capabilities are mapped (41). Communication capabilities available in the first communication network are allocated (42) for use by the second communication network, and the allocated data communication capabilities are advertised (43) to the second communication network, represented in accordance with the attributes mapping (41).
