Communication systems, such as an evolved packet system, may benefit from various interworking functions. In particular, certain communication systems in which machine type communication devices are deployed may benefit from a machine type communication interworking function in a visited network. A method may comprise receiving, from a network element, a request in a visited machine type communication interworking function. The method may also comprise processing the request in the visited machine type communication interworking function. The method may further comprise sending a response to the network element in response to the request.
