The present invention relates a user equipment UE registered for Non-IP communication services performs an application function. For providing application data via a radio access network, a method involves receiving a paging message and a subsequent radio link control, RLC, message in accordance with a Non-IP communication protocol. The paging message and the RLC message are initiated by an application server associated with the application function. The UE retrieves a network address of the application server in accordance with an IP communication protocol stack, and activates use of the IP communication protocol stack. The UE then requests IP communication services from the core network via the wireless cellular network, obtains a dynamic network address in accordance with the Internet Protocol and uses its dynamic network address and the network address of the application server to providing the application data to the application server using the IP communication services via the wireless cellular network.
