摘要
The paper discusses the significance and development foreground of co-operation among heterogeneous networks in composite radio context for B3G wireless communications. The concept of composite reconfigurable wireless network is introduced in the paper, and the development of future wireless communication systems is also discussed. The basic configuration framework of the network interoperation is given, and the functions of important parts are analyzed. A management platform for co-operation between WLAN and cellular network is introduced, adding several models to the original systems. Furthermore, new radio access schemes for different types of Mobile Terminals (MTs) are proposed. Particularly, Spectrum Sharing (SS) between WLAN and cellular networks is discussed. Here, a new radio access scheme and channel assignment mechanism with code-division duplex (CDD) and Frequency Hopping (FH) technologies are raised, for the purpose of avoiding interference between heterogeneous networks Finally, the performance of the above radio access schemes is analyzed, and simulation results proved its validation.
