To provide a possibility to have a near-real-time replay of a pre-empted communication while ensuring that the pre-empting communication is not interrupted, when it is detected that a pre-empting communication is pre-empting a pre-empted communication, the pre-empted communication is buffered to a buffer for a replay, and a safety interval for the pre-empting communication is determined. The pre-empting communication is determined to be ended in response to an expiry of the safety interval after end of the pre-empting communication.

Handling a pre-empted communication

A method for improved application of unreliable transfer mechanisms. An application uses application data delivered in data packets that become accessible from a peer entity via at least two packet data transmission mechanisms. The application is configured with a predefined operational range for a predefined application-specific characteristic. If the predefined application-specific characteristic exceeds the predefined operational range, the packet data transmission mechanism is changed. The mechanism facilitates maintaining an application-specific service level even if unreliable transmission mechanisms are applied.
