移动通讯演进到LTE,要求端到端全IP传输,并在此基础上,对业务的支持从单一的话务业务扩展到包括数据、语音、视频等各种应用服务。由于相对于有线网络,无线网络存在高时延、低带宽和不稳定等因素,所以在测试方面,除了进行L2～L3性能测试以外,需要从用户体验角度出发,进行真实业务服务质量的验证。思博伦通信赵隽琪所撰《思博伦LTE端到端业务质量测试解决方案》一文详细介绍了思博伦通信LTE端到端业务质量测试解决方案。此方案可以从基本功能和性能,QoS能力,真实应用业务仿真和质量测试,现网应用场景测试等方面对LTE系统进行端到端的研发测试、选型验证和运维验证。
Mobile communications evolve to LTE and require end-to-end all-IP transmission. On this basis, the support for services extends from a single traffic service to various application services including data, voice and video. Due to the high latency, low bandwidth and instability of wireless networks relative to wired networks, in terms of testing, in addition to performing L2 ~ L3 performance tests, it is necessary to verify the real service quality of service from a user experience perspective. Spirent Zhao Junqi, author of “Spirent LTE end-to-end business quality test solutions,” a text detailing Spirent LTE communications end-to-end business quality test solutions. The solution can carry out end-to-end R & D and testing, selection verification and operation and maintenance verification of LTE systems in terms of basic functions and capabilities, QoS capabilities, real-world application service simulation and quality testing, and live network application scenario testing.
