近年来随着全球无线数据流量爆炸式增长,中国移动网络的数据业务流量已经快速超越了语音业务量。面对高速增长的移动数据业务,如何充分发挥GSM、TD-SCDMA、TD-LTE、WLAN等网络的优势,建设一张高带宽、高效率、低成本的无线网络是中国移动目前必须解决的问题。文中在分析了上述四个网络的技术特点的基础上,详细分析了它们目前的建设现状,并在此基础上对四网协同发展的策略进行了讨论。
In recent years, with the explosive growth of global wireless data traffic, the data traffic of China’s mobile network has rapidly exceeded the voice traffic. In the face of the rapid growth of mobile data services, how to give full play to the advantages of GSM, TD-SCDMA, TD-LTE, WLAN and other networks to build a high-bandwidth, high-efficiency and low-cost wireless network is China Mobile must solve the problem . Based on the analysis of the technical characteristics of the above four networks, the current status quo of their construction is analyzed in detail. On the basis of this, the strategies for the coordinated development of the four networks are discussed.
