context: Figure 5.3.2.1.1.1.1 shows the Diameter transactions that are required between AS implementing the CDIV service and OCS, when online charging is applied to a successful CFU communication. Figure 5.3.2.1.1.1.1: Message sequence chart for online charging of CDIV service - establishment A communication is requested towards User B: CFU and online-based charging activated for user B. 1. SIP INVITE request incoming for User B. Based on the iFC, indicating that User B is subscribed to the CDIV supplementary service, the communication is forwarded to AS implementing CDIV, where CFU is detected. 2. As the subscriber is "online charging", the AS sends a Reserve Units Request [Initial, service CDIV, ICID..] to the OCS for requesting units for the CDIV (CFU) supplementary service. 3. The OCS grants units in the Reserve Units Response response for this request. 4. The CDIV (CFU) can now be delivered: a SIP INVITE is sent towards user C via the S-CSCF. Any potential announcements to be played to the
description: Communications Diversion (CDIV) is a supplementary service that enables the diversion of communications, such as calls or messages, from one user to another. It involves the forwarding of incoming communications to a different user, based on the subscriber's preferences and settings.
explanation: The context describes CDIV as a feature activated for a user, involving online charging and interactions with systems like the Application Server (AS) and Online Charging System (OCS). This points to it being a telecommunications service rather than a hardware component or network infrastructure.
