This page describes the architecture of Sentinel and its relation with the network.
Below is a high-level diagram of Sentinel and its relation with the network.
The Sentinel platform connects to network elements (Switches, HLRs, GGSNs, and so on) and to one or more online charging system. The sentinel platform consists of:
the Sentinel application server (based on the OpenCloud Rhino platform)
the Sentinel subscriber database
the Sentinel promotions database
the Sentinel Element Manager, which provides a web-based interface, a machine-to-machine interface, and an XCAP server framework.
Below is a high-level diagram of the architecture of the Sentinel platform.
There are three layers:
Session control — There is a SLEE service per triggering protocol (such as SS7 or Diameter).
Mediation — The mediation layer provides a charging interface to session control and connects to one or more online charging systems. The mediation layer uses Diameter Ro as its internal charging protocol and provides different methods of charging control (such as SCUR or IEC).
OCS — The OCS layer includes a set of OCS drivers that connect Sentinel to different types of OCS; for example, an OCS that exposes a standard Diameter Ro interface, or an OCS that exposes a proprietary charging interface.
The Sentinel application server also includes configuration data related to:
