VoLTE deployment introduces a new network element, the MMTel TAS for IR.92 and IR.94 services, and removes the need for Circuit Switch Fall Back (CSFB) for the support of Voice Services for the new LTE subscribers.
This of course means that the new VoLTE subscribers are now no longer able to access the legacy IN services on the 3G network for their voice calls, and in turn operators must provide an installed base that is both substantial and mission critical for the transition of their Intelligent Networking features.
Today Service Delivery is aligned with access network silos, but with the deployment of next generation networks these silos must converge. The AGNITY CAS platform bridges the 3G/legacy/TDM network and the 4G/IMS/IP network in order to provide legacy applications and a platform for future application development independent of but in conjunction with TAS.
AGNITY Communications, Inc. offers solutions that address these needs with the industry’s best of breed applications infrastructure:
Communications Application server (CAS) – a virtualized, standards based converged Service Delivery Platform that works across 3G, 4G LTE, WiFi and VoIP. It bridges legacy and next generation networks either via its Service Broker functionality or by deploying in a Hybrid Configuration, a patent pending solution (commercially deployed) for ensuring feature parity for subscribers across any access network.

Next Generation IN (NGIN) Services – applications, including network based VPN, Number Portability, Advanced Call Routing (ATF) / IVR, Prepaid and Online Charging System, to allow replacement of existing legacy IN features as the current platforms reach EOL or fail to support next generation interfaces.
Service Broker Capabiliy – the ability to “reach” back to a legacy IN platform from the new IMS core network in order to provide access to legacy applications on platforms that the Service Provider intends to keep in service in order to extract maximum life and value from the asset.
Migration Tools and Methodologies – extensive tools, capabilities and experience to achieve the goal of parity between new systems and legacy systems with minimal impact to network operations.
