VoLTE calls for an effective bandwidth and QoS policy management

 

VoLTE (Voice over LTE) is a typical mobile network technology that enables IP-based high-definition voice service experience across a multitude of different devices and end-points, using the IP Multimedia Subsystem (IMS). Unlike the Circuit Switching (CS) domain where calls are delivered with a fixed QoS and bandwidth, in the Packet Switching (PS) domain, the voice channel competes for bandwidth with all the other data services. Consequently, an effective data network policy management is essential for VoLTE service delivery and monetization.

 

Differentiation and prioritization of traffic flows

Opencode’s VoLTE PCRF is designed to properly reserve and prioritize the appropriate network resources so that VoLTE QoS requirements are met. A key component in the LTE network, the system provides the association between the service and transport layers and is the central QoS decision engine. Opencode VoLTE PCRF enables the network to recognize and differentiate traffic flows - a fundamental LTE concept. The system also provides a granular control of service quality, which is crucial for managing resources, establishing new business models, and monetizing HD voice services.
