摘要: A method, at a user equipment (‘UE’), the method: sending request to first network for Circuit Switched Fallback (‘CSFB’); receiving, responsive request, redirection information; acquiring second based on initiating establishment of (‘CS’) voice radio bearers with network; waiting predetermined event occur; after has occurred, establishing Packet (‘PS’) connection network. Further, element, method receiving (‘CSFB’) from (‘UE’); sending, UE, Routing Area Update (‘RAU’) message UE; upon occurring, responding RAU message.
