Abstract
A method and network node for terminating an IP Multimedia Subsystem (IMS)-enabled communication service involving a user terminal, which has been allocated an IP address by an access network used by the terminal to access the communication service. Upon determining that the IP address is no longer allocated to the user by the access network, the node terminates the IMS communication service.
