| 摘 要： | 为了更好地保证端到端的QoS机制,为用户提供差异化服务体验,EPS系统支持通过EPS承载对分组数据进行传送。通过对业务流模板(TFT)的研究,了解UE中上行分组过滤器(UL_PF)与EPS承载的关系,研究上行IP分组包与分组过滤器(PF)的匹配过程,给出一种PF与IP分组包之间的匹配实现方案,最终实现IP数组在EPS承载上传输。

| Abstract: | In order to ensure the QoS mechanism of end to end to provide the experience of differential service for users better,the EPS system transports the packet data by the EPS bearer.In this paper,the Traffic Flow Template(TFT) is studied to comprehend the relation between the uplink packet filter(UL_PF) and the EPS bearer,to research the matching process of the uplink IP packet and the Packet Filter(PF).After these research,one matching process scheme between the uplink IP packet and the PF is put forward,which realizes the IP data transmitted through the EPS bearer. |
