1. A method by a network node of a communications network, the method comprising:
determining a data traffic inactivity timer value based on subscriber event data, which identifies a subscriber and service characteristics using a communication session, being processed through a predictive model which uses historical usage data indicating idle times previously measured by charging trigger functions, CTFs, for the subscriber and the service characteristics; and
communicating the data traffic inactivity timer value to a CTF to configure monitoring of inactivity of the service using the communication session and to trigger a release operation related to the communication session when a data traffic inactivity timer using the data traffic inactivity timer value is determined to expire based on the monitored inactivity of the service.
