摘　　要：针对移动数据业务未在核心网侧部署区分业务的带宽分配策略问题,提出了一种基于GGSN的面向业务的带宽分配方法。该方法利用分形布朗运动模型和G/D/1(n)排队模型分析不同业务的带宽需求,并结合GGSN设备功能及带宽资源情况,实现了面向业务的移动数据业务带宽分配。理论分析和仿真结果表明,该方法能有效地区分不同业务的服务质量并保障高价值业务的带宽需求。Aiming at solving the problem that no service-oriented bandwidth allocation strategy was deployed for mobile data service in core network, a service-oriented approach to bandwidth allocation based on GGSN was proposed. The approach achieved the service-oriented bandwidth allocation for mobile data service making use of the bandwidth demands of different services derived from the FBM traffic model and the G/D/I（n） queuing model, combined with the function of GGSN equipment and the situation of bandwidth resources. Theoretical analysis and simulation results indicate that the proposed approach ＇can effectively classify the quality of different services and guarantee the bandwidth demands of high-value services.
