摘　　要：随着下一代互联网NGI（NextGeneration Internet）技术迅速发展且应用日益广泛，用户总希望得到总最佳连接ABC（Always Best Connected）。为了保证用户的ABC支持型切换，提出了新型资源预约机制。利用模糊数学、博弈论等知识建立模型，刻画网络类型、服务质量QoS（Quality of Service）、终端等。提出了粗资源预约算法和细资源预约算法，同时运用了两种计算预约概率的方法。两种算法和两种方法组合得到四种机制（机制1—4），利用NS2对这四种机制进行仿真。仿真结果表明，机制1和机制3最有效，性能最好。With the rapid development of the NGI （Next Generation Internet） technology and its widespread application, users always hope to get the ABC （Always Best Connected） to NGI. To guarantee the user handoff with ABC supported, a new resource reservation scheme was put forward. Knowledge of fuzzy mathematics and game theory were used to establish system model and depict network type, QoS （Quality of Service）, terminal, etc. The coarse andfine resource reservation algorithms were put forward and two methods of computing reservation probability were utilized. Four schemes （scheme 1-4） were obtained from combining the two resource reservation algorithms and the two reservation probability computing methods, and simulated over NS2. Simulation results have showed that scheme 1 and scheme 3 are most effective and have best performance.
