name: CTF
full_form: Charging Trigger Function
context: Online Credit-Control uses two basic logical operations: Debit Units and Reserve Units. - "Debit Units Request"; sent from CTF OCF After receiving a service request from the subscriber, the CTF sends a Debit Units Request to the OCF. The CTF may either specify a service key (centralised unit determination) or the number of units requested (decentralised unit determination). For refund purpose, the CTF sends a Debit Units Request to the OCF as well. - "Debit Units Response"; sent from OCF CTF The OCF replies with a Debit Units Response, which informs the CTF of the number of units granted as a result of the Debit Units Request. This includes the case where the number of units granted indicates the permission to render the requested service. For refund purpose, the OCF replies with a Debit Units Response. - "Reserve Units Request"; sent from CTF OCF Request to reserve a number of units for the service to be provided by an CTF. In case of centralized unit determination, the CTF specifies
description: The Charging Trigger Function (CTF) is responsible for triggering charging events and managing credit control in online charging scenarios within the telecommunications network.
explanation: CTF is classified as a Network Function because it performs specific tasks within the network infrastructure, such as initiating charging processes, interacting with other network functions like the Online Charging Function (OCF), and ultimately influencing billing and usage management.
