摘要
上一期中,我们论述了策略管理和QoS在无线网络中的作用,并介绍了3GPP所定义的实现方式。在本期中,我们将继续讨论QoS和策略管理的测试方法,并介绍IXIA在一个北美运营商实验室里实现VoLTE测试的成功案例。
In this paper we will explore the growth in mobile data, and examine how this growth impacts QoE by placing heavy strains on wireless network resources. We will review 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, we will discuss techniques to validate service quality for mobile broadband and explore a voice over LTE （VoLTE） QoS-validation use case from a tier-one operator.
