Description

业务数据的传输方法和装置 技术领域
本发明涉及通信领域，尤其涉及业务数据的传输方法和装置。
背景技术
目前，网络侧设备尤其是接入网仅仅可以根据有限的业务信息设置传输承载，并进行业务数据的传输。在长期演进(Long Term Evolution，LTE)系统中，微信、优酷等具体业务的业务数据通过业务流模板(Traffic Flow Template，TFT)映射在对应的分组核心网(Evolved Packet Core，EPC)承载中，最终传输到分组数据网络网关(Packet Data Network Gateway，P-GW)，完成用户设备(User Equipment，UE)和业务服务器的之间的数据交互。
网络侧设备提供的业务数据传输通道在最初建立的时候已经确定了可以提供的服务质量。然而，同一个业务不同的时期或者不同的数据包对服务质量的要求都有不同，现有的服务质量保证机制并不能灵活的根据业务数据需求调整承载的传输参数。主要是因为演进基站(Evolved Node B，eNB)、服务网关(Serving Gate Way，S-GW)、P-GW等网络侧设备，并不知道具体在该承载传输的业务数据的对传输参数的需求信息，因此很难精准的为该业务数据提供合理的质量服务。
