摘要
从网络的发展过程看,GSM网络在中国经过多年的发展,基本达到了全国城乡地区的无缝覆盖,拥有大量用户。GSM网络以其成熟的技术、稳定的设备性能和高性价比等特点,成为最适合为多数人提供无线通信服务的网络。可以预计,在像中国这样人口多、分布广的国家,GSM网络在较长一段时间内仍有充足的发展空间。与此同时,国内LTE网络正在规模建设中。在进行LTE网络建设的过程中,网络不仅要支持传统的语音业务,同时也需要满足各类数据业务的发展。GSM,LTE网络将在未来很长一段时间内共存,这种组网策略对于GSM和LTE系统之间的互操作提成了强烈的需求。着重从GSM到LTE的小区重选以及CSFB这两个方面分析了GSM和LTE之间的互操作。
With large-scale construction of LTE（ Long Term Evolution）, the network should not only sup- port the traditional voice services, but also meet the requirement of data services. And in the same time, GSM （Global System for Mobile Communications） is the main solution to voice services, for its technical maturity, reliable equipment, and high ratio of performance cost, and would still have adequate develop- ment space in a fairly long time. And thus GSM and LTE network would coexist for a long time in future. This networking strategy proposes an urgent demand for the inter-operation of between LTE and GSM. This paper analyzes the inter-operation of between LTE and GSM from two aspects of cell reselection and CSFB （Circuit Switched Fallback）.
