Virtual IMS represents a new growing category of core IMS functions designed to be deployed in a cloud infrastructure, fueled by several macro trends such as massive VoLTE growth and Internet of Things, to name just a couple.

The main challenges service providers have are

  • Expansion of existing IMS core to accommodate VoLTE growth is not feasible given the economies of what we call the first wave of IMS
  • New services, such IOT, have an unknown traffic pattern, which operators don’t want mixing with traffic running on their existing core
  • New markets, or regional geographic coverage, present the same economical challenge of adding more traditional IMS elements

Clearwater Core provides the first cloud-native complete IMS core solution, fully delivering on NFV promise: NFV auto-scaling and auto-healing, limitless application server chaining and linear scaling and a disruptive economical model.

Built with a fundamentally new approach to developing, delivering and deploying communications networks, Clearwater Core provides all the cloud-native design benefits.

Significantly Reduced TCO

Clearwater Core delivers more than three times the TCO savings that existing solutions do. A simplified example below shows the difference between the existing approach and Clearwater Core, based on cloud-native scaling architecture versus existing ones, and local and geo redundancy requirements.

  Clearwater Core Ported software
Architecture N+k 6 site 1:1 2 site
Local redundancy HW factor 1.1 2
GR HW factor 1.2 2
Hypervisor overhead 1.1 1.1
Total HW needs 1.45 4.40

Rapid time to market

Clearwater Core can be up and running in a matter of days, giving operators the ability to reduce the time to market of new services drastically, therefore increasing the revenue stream with very low risk and investment.

Grows with your business

Clearwater Core provides the following functional elements:

  • I-SBC/IBCF
  • A SBC/P-CSCF/ATCF
  • I/S CSCF
  • CCF
  • BGCF
  • AGCF/MGCF
  • TrGW
  • ATGW
  • MRF

All components are designed as elastic, resilient and high-performance core functions that are the reference cloud-native VNF design for Tier 1 service providers around the globe and widely used to validate NFV models and tools by carriers globally.

Furthermore, the microservice architecture provides the needed foundation for new services, or most efficient utilization of resources for existing services.
