The Rhino Service Interaction SLEE provides service interaction for circuit-switched networks.

Specifically, SIS lets you:

  • run one or more services on a trigger from a Service Switching Function (SSF) or Serving Call Session Control Function
    (S-CSCF). These services may be:

    • local: JAIN SLEE services written using OpenCloud CGIN or EasySIP APIs:

      • SIS supports CGIN APIs for:

        • GSM CAP v1, v2, v3, and v4 (Voice and SMS only)

        • ETSI INAP CS1

        • Ericsson INAP CS1 (optional)

        • Ericsson INAP CS1+ (optional)

        • Nokia INAP CS1 (optional); Siemens INAP 7m+ (optional)

        • GSM MAP v4 (outgoing dialogs only).

      • EasySIP supports SIP (RFC 3261) and ISC (3GPP TS 23.218).

    • external: legacy CAP and INAP services in external network elements, or SIP application servers.

  • fully customise how the SIS selects the service composition (set of services) to run, using initial trigger scripts

  • manage the signaling interactions between the services that the SIS invokes, with powerful and flexible composition scripts

  • enable focused, service-interaction tracing for specific dialogs, without compromising the performance of the SIS, by using fine-grained tracing options for specific service compositions, address or service-key subscriptions, or arbitrary addresses from initial events.
