ORLANDO, Fla. -- Acme Packet® (NASDAQ:APKT), the leader in session delivery network solutions, today announced enhancements to its Net-Net® Session Director for voice over LTE (VoLTE) that will enable mobile service providers to deliver seamless and reliable voice call handover to 2G/3G networks when subscribers leave LTE coverage areas. These new features, added to the industry’s leading session border controller (SBC), address newly defined IP Multimedia Subsystem (IMS) functions for call continuity for VoLTE.

Call continuity for VoLTE

The initial deployments of VoLTE, expected to begin in the next 12–18 months, will be gradual and require 2G and 3G circuit-switched networks to augment LTE coverage areas for ubiquitous coverage for voice and messaging. To accommodate this need, the 3rd Generation Partnership Project (3GPP) defined Single Radio Voice Call Continuity (SRVCC) as the mechanism to move active voice calls between LTE and 2G/3G circuit networks. SRVCC uses a single radio at any given time—LTE or 3G, for example—rather than dual active radios to preserve endpoint battery life. A VCC application server is used as a centralized signaling anchor point for handover when the phone’s LTE radio loses its connection and the 2G/3G radio establishes its connection.
