context: Figure 4.3.1.0.1 provides an overview of the offline part of the common charging architecture of Figure 4.2.2.1. The figure 4.3.1.0.1 depicts the logical charging functions as well as the reference points between these functions and to the BD. CTF: Charging Trigger Function CDF: Charging Data Function CGF: Charging Gateway Function BD: Billing Domain. This may also be a billing system/ billing mediation device. Figure 4.3.1.0.1: Logical ubiquitous offline charging architecture NOTE: Although not visualised in this figure 4.3.1.0.1, the OCS can also produce CDRs, i.e. act as a domain / service / subsystem element with embedded CTF, see clause 4.3.2.3.
description: The Charging Trigger Function (CTF) is a logical network function within the common charging architecture of the 3GPP's telecommunications specifications. It plays a crucial role in triggering the generation of charging data, which is then processed by other functions such as the Charging Data Function (CDF) and the Charging Gateway Function (CGF). The CTF interacts with these components through reference points to facilitate the offline charging process. Additionally, it can be embedded within the Online Charging System (OCS), enabling it to produce Charging Data Records (CDRs) as part of its functionality.
explanation: CTF is classified as a Network Function because it serves as an integral component in managing and triggering charging-related processes within the telecommunications network. Its role in interacting with other logical functions and producing charging data aligns with the 3GPP's specifications for efficient charging operations.
