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。
In order to ensure the QoS mechanism of end to end to provide the experience of differential service for users better, the EPS system trans- ports the packet data by the EPS bearer. In this paper, the Traffic Flow Template （TI;＇F） is studied to comprehend the relation between the uplink packet filter （ UI. PF） and the EPS bearer, to research the matching process of the uplink IP packet and the Packet Filter （PF）. After these research, one matc- hing process scheme between the uplink IP packet and the PF is put forward, which realizes the IP data transmitted through the EPS bearer.
