Abstract
Systems, methods, and apparatuses are provided for handling a legacy circuit switched communication. A method may include receiving a service request message at a network node on a packet switched network that does not support circuit switched fallback. The method may additionally include determining that the service request message includes a request for establishment of a communication requiring a circuit switched connection and having a user equipment connected to the packet switched network as an end point of the communication. The method may further include releasing the connection between the user equipment and the packet switched network in response to the determination. Corresponding systems and apparatuses are also provided.
