The first retry-after time may indicate the second network function (102) to stop sending a message for a User Equipment (UE) (106) before the first retry-after time is timeout. The method (500) may further comprise the step oftransmitting (S502) based on the first message, to a third network function (103) implementing a Policy Control Function (PCF), asecond message including a second parameter indicating a second retry-after time during which the UE (106) is considered unreachable.
