摘要： A method performed by a network node for preventing a release of a connection from a User Equipment, UE, to the network node, which connection uses a Real Time Protocol, RTP, for media transfer. The network node operates in a wireless communication network and serves the UE. The network node detects a gap in a packet- flow of the connection. When the network node has detected a gap in the packet flow, the network node prevents the UE from initiating a release of the connection caused by the gap in the packet flow, by sending a message to the UE, which message forces the UE into a failure. The failure triggers the UE to initiate a Radio Resource Control, RRC, Connection Reestablishment procedure.
