摘　　要：目标系统、演进路线和频谱使用方式是发展下一代移动通信接入网涉及的问题。目前在目标系统的设计思想、协同机制、建模方法等方面还存在一些理论困难,为了构建下一代移动通信接入网的理论基础,需要开展跨学科研究。作为现有网络的多网协同演进示例,讨论了以地面数字电视广播和移动通信网协同发射为基础,跨系统构建手机电视标准以及实现TD-SCDMA与地面数字电视广播网和有线电视网的协同方法。在频谱使用方式上,提出一种基于协同发射的频谱交易方式。The target systems, evolution readmaps and the manner of spectrum usage are factors concerning the development of the radio aceess network （RAN） of the next generation mobile communieation system. Sinee there exists some theoretie diflieulties,a theoretie foundation needs to be set up before the analysis of the system eharaeteristies and the system modeling method for next generation mobile communieation RAN. Therefore, it is neeessary to resort to the inter-diseiplinary studies. To give some examples of the cooperative evolutions among the existing RAN, the eooperative transmission between the mobile eommunieation RAN and the digital broadeasting RAN was discussed, as well as the mobile TV standard based on eombining TD-SCDMA and DMB-TH, and the eooperation among TD-SCDMA, DMB-TH and HFC network. Finally, a speetrum trading method based on the eooperative transmission teehnique was proposed.
