摘要
随着LTE(Long Term Evolution)的大规模建设,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。与此同时,GSM(Global System For mobile Communications)的技术成熟、设备稳定、性价比高,是目前语音业务的主要解决方案,在未来较长一段时间内仍有充足的发展空间。可以预计,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出了强烈需求。着重从GSM到LTE的小区重选以及CSFB(Circuit Switched Fallback)两方面分析了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）.
