context: Figure 5.2.2.1.9.1.1 and figure 5.2.2.1.9.1.2 show the Diameter transactions that are required between ASs implementing the ECT service (for the transferor and for the transferee) and CDF: a successful Blind Transfert from User A to User C, initiated by User B. For diagram simplification, only one CDF is shown. Figure .1.9.1.1: Message sequence chart for offline charging of ECT service â Blind Transfer (part1) Figure 5.2.2.1.9.1.2: Message sequence chart for offline charging of ECT service â Blind Transfert (part 2) In this scenario User A is the transferee, User B is the transferor, and User C is the transfer target. User A and User B are in an established communication for which, based on the Initial Filter Criteria (IFC) rules indicating that User B is subscribed to the ECT supplementary service, the SIP INVITE was forwarded to an AS implementing ECT (for User A and User B). User B puts User A on Hold. 1. User B sends SIP REFER request in the existing A-B dialog, to initiate
description: Explicit Communication Transfer (ECT) is a procedure that enables the transfer of an ongoing communication from one user to another. It involves a series of Diameter transactions between Application Servers (ASs) and the Charging Data Function (CDF), as well as SIP signaling between users.
explanation: The context describes ECT as a service that allows for blind transfers, where a user can transfer an ongoing call to another user without the consent of the transferee. The procedure involves multiple steps, including the sending of SIP REFER requests and the exchange of Diameter messages between ASs and CDF. This classification is based on the detailed description of the ECT procedure in the provided context.
