Zusammenfassung:	An enhanced Circuit Switch Fallback enabled Heterogeneous Network (HETNET) is provided by the present invention in which the 1×IWS functionality is co-located with LTB eNB. It also tunnels 1×RTT over LTE messages directly to the Convergence Server over SIP, Further, it enables distributed PN-FAP identification determination. A mobile management, entity is configured to maintain multiple 1×CS IWS tunnels. Multiple 1×CS IWS tunnels are established, by using the same S1 tunnel end point used in establishing a Borne evolved Node B Gateway of the HETNET. The HETNET is configured to provide a correct FAP identification to the convergence server so that handover preparation can be done.
