Guaranteed QoS in VoLTE Environments

Flow-based quality of service guarantees high quality of experience for VoLTE

With the evolution of mobile networks from traditional circuit-switched to IP-based, Voice over LTE (VoLTE) networks, delivering end-to-end quality now requires the ability to perform flow-based quality of service (QoS). Unfortunately, much like legacy networks, many vendors have not kept up with industry standards or the technologies required to deliver the ability for communications service providers (CSPs) to guarantee quality of service in VoLTE environments.

Sandvine’s access-agnostic policy control platform operates not only as a universal policy controller for your traditional data networks (2G, 3G, CDMA, Cable, DSL, etc.) but is optimized for LTE and VoLTE environments, enabling LTE operators who have deployed VoLTE services to protect and guarantee QoS with their IP-based, VoLTE calls.

Additionally, by leveraging Sandvine’s VoLTE-enabled PCRF (that supports 3GPP Rx and Gx interfaces), LTE operators can protect and guarantee flow-based QoS for VoLTE calls, while exposing measurements to report on VoLTE QoE achieved by VoLTE-based calls on the network.
