A wireless device is configured to operate in first and second access networks. The first and second access networks respectively provide access to first and second core networks of different types. A first wireless communication network includes the first access network and the first core network. A second wireless communication network includes the second access network and the second core network. The wireless device is configured to receive, from the first access network, control signaling indicating that the wireless device is to suspend a connection with the first access network and indicating a notification area within which the wireless device is allowed to move without notifying either the first and second wireless communication networks. The control signaling indicates the notification area includes one or more areas of the first wireless communication network and one or more areas of the second wireless communication network.
