NB-IoT独立部署下的容量性能分析
|
摘要
NB-IoT作为新兴的物联网技术,已经临近商用阶段,但暂无可行的方案用于NB-IoT小区容量的测试,因此将介绍一种容量评估方法,根据3GPP标准定义的业务模型、用户分布模型和外场试验的配置参数,通过NB-IoT一次业务的资源消耗分析NB-IoT下行业务信道容量、随机接入容量和上行业务信道容量,得出NB-IoT小区的综合容量。
As the newly burgeoning IoT technology, NB-IoT is facing commercial phase. However, there is no applicable scheme to test the capacity of NB-IoT cells. A capacity evaluation method is introduced. According to the traffic model, user distribution model and outfield experiment configuration parameters defined by 3GPP specifications, the NB-IoT downlink traffic channel capacity, random access channel capacity and uplink traffic channel capacity were analyzed based on the resource consumption of one NB-IoT traffic to derive the overall capacity of NB-IoT cells.
