In a method for securing communication links and associated charging in a redundantly configured communication network in which terminals communicate via bearers, and via hardware units by means of messages, a monitoring function is used to monitor a correct functioning of at least one of the terminals, the bearers and the hardware units. If at least one of the hardware units fails, a physical function of a failed hardware unit is taken over by at least one functional hardware unit. After takeover, a message is transmitted by the at least one functional hardware unit to a terminal affected by a failure. The at least one functional hardware unit establishes that the monitoring function is executed by the at least one functional hardware unit. If a transaction is ongoing, a signal from a failed hardware unit is transmitted to a functional hardware unit such that overcharging for the transaction is avoided.
