                    介绍了第三代移动通信系统(3G)和无线城域网WiMAX系统联合组网的优势和应用场景,对基于3G系统的接入控制和计费的WiMAX系统联合组网方案进行了详细阐述,给出了体系架构、关键信令流程和加密安全(AAA)等机制。
                
                The paper introduces the network interworking between the third generation systems (3G) and the WiMAX system,in which the advantage and application scenario are both involved.Based on the 3G's admission control and counting mechanisms, the WiMAX system can access the core network.This paper investigates some research problems:the architecture,the key signal processing,and the AAA mechanisms.
