摘要：Methods of re-establishing a connection between a radio network node and acore network having a control plane entity and a user plane entity in a communicationnetwork and of detecting faulty communication paths or re-started entities in such

networks are provided. A control-plane entity sends an event in accordance with a mediagateway control protocol to the user-plane entity that orders the user-plane entity tonotify the control-plane entity when user-plane traffic is received from another networknode or when a faulty path or re-started peer is discovered. In response to an order bythe control-plane entity, a connection between the radio network node and the user-plane entity can be re-established. Heartbeat messages and heartbeat acknowledgmentmessages are sent through a communication path, and if a heartbeat acknowledgmentmessage has not been received, the control-plane entity is notified of the faulty path.The heartbeat acknowledgment messages may include re-start counter values that areused to discover re-started peers.
