The policy and charging control (PCC) is the heart of the Evolved Packet Core (EPC), and ensures user QoE for a particular subscription and service type.
This white paper explores the growth in mobile data, and examines how this growth impacts QoE by placing heavy strains on wireless network resources.
The paper reviews how wireless networks are evolving from primarily voice-only services to converged voice, video, and data traffic, and how operators can use the emerging 3GPP standards for QoS and policy management to ease network congestion, provide higher service quality, and create a framework for new business models.
Finally, it discusses techniques to validate service quality for mobile broadband and explore a voice over LTE (VoLTE) QoS-validation use case from a tier-one operator.
