Abstract: A method for processing a connection-mode IP connection is provided. Generic methods known from the prior are problematic in that in the case of connection-mode IP communication connections between two control devices the connection-mode data are lost in one of the control devices after a non-availability situation and thus the messages received cannot be associated with a connection. The method provides that the messages emitted by the sending control device are made available to the upper layer of the connection-mode communication connection, which uses the same as a criterion for the preferential recovery of intact connections.

Abstract: A method for transmitting signaling information via a network limiting element, which interconnects a packet-switched communications network and a circuit-switched communications network is provided. The network limiting element having interfaces that are respectively connected to the packet-switched communications network by a message-oriented control channel and a connection-oriented control channel. At least one of the interfaces comprises an active connection unit and a redundant connection unit. The method is characterized in that during a changeover from the active connection unit to the redundant connection unit, a state transmission is carried out between the message-oriented control channel and the connection-oriented control channel in such a way that the connection-oriented signaling is controlled by the message-oriented signaling.
