As operators consolidate and add new access technologies including broadband wireline (such as xDSL and FTTx), wireless (such as WiMax and LTE) or cable (HFC), IP Multimedia Subsystem (IMS) has gained attention as a core network component. In this context, IMS provides a framework for deploying services and applications irrespective of the access technology, leading to seamless service with the most efficient use of available resources. IMS facilitates the rapid deployment of new services, presenting new revenue sources for service providers.

 

  • The challenges

    The success of IMS depends, to a large extent, on the ability of service providers to eliminate the complexity of the operational challenges introduced by this revolutionary technology:

    • Multi-domain consolidation
      New network components and software applications must be monitored, or as a minimum, network management platforms that were previously have to be consolidated.
    • Control plane integration
      IMS control plane components have to be integrated into existing management solutions during the operators’ network transformation phases.
    • QoS and resource reservation
      QoS and resource-reservation-support at the edge of the network become a key success factor maintaining customers’ satisfaction and loyalty.
    • Time-to-market requirements
      OSS is expected to offer service providers the flexibility and agility to deploy and manage new IMS services quickly and at minimal cost in order to attain commercial value from its deployment.

     

  • What we provide

    To achieve effective support for IMS, service providers must enhance their OSS solutions to include:

    • Centralized supervision, abstraction and visualization for the underlying multi-vendor and multi-domain network infrastructure.
    • Joint service model including network infrastructure, IMS service and session control, services and customers.
    • SIP and diameter protocol monitoring and analysis.
    • Scalable data collection platform to handle current and future high-volume management data while maintaining superior performance.
    • Analysis tools that can provide an updated status of the level of service the IMS infrastructure provides to the carried services.
    • Monitoring internal and external SLO (Service Level Objectives) violations and warning, before a certain SLO is crossed.
