What it does
The charging service communicates with a number of possible systems to charge subscribers for making and receiving calls. The Rhino VoLTE TAS supports three different charging methods:
-
offline charging using Diameter Rf to send reports to a Charging Data Function (CDF)
-
online charging using Diameter Ro protocol to communicate with an Online Charging Server (OCS)
-
online charging using SIP to CAP translation to communicate with a charging Service Control Point (SCP) in a GSM network.
Online and offline charging can be used simultaneously. It is also possible to use both types of supported online charging at the same time. The Rhino VoLTE TAS does not support CDMA based charging systems, so for those networks only Diameter based charging is available.
Additionally, the Rhino VoLTE TAS writes Charging Data Records (CDRs) for every call. These contain metadata about the call suitable to use for charging purposes.
