这里需要说明的是,核心网节点直接生成的第一信息通常包括的是上述的A12-A19中的至少一项,当根据直接生成的第一信息对业务数据进行映射得到QoS流后,核心网节点便会获取到该QoS流对应的QFI,也就是说,此种情况下,核心网节点是根据直接生成的第一信息映射得到QoS流,进而获取到发送给接入网节点的第一信息(此种情况下,第一信息指的是上述的A11),并通过QoS流将A11通知给接入网节点。
进一步还需要说明的是,核心网节点根据第一信息对业务数据进行映射,获取QoS流的主要实现方式为:根据预设映射规则,将业务数据映射到QoS流;

需要说明的是,该第一优先级的业务数据可以为优先级高的业务数据,该第一QoS流为预先设置具有高优先级的QoS流,第一QFI的QoS流为QFI的取值较小/较低的QoS流;也就是说,此预设映射规则是将高优先级的业务数据映射到具有高优先级的QoS流或QFI取值较小/较低的QoS流。
例如,I帧映射到第一QoS flow,非I帧映射到第二QoS flow;或,I帧映射到QFI=1的QoS flow,非I帧映射到QFI=2的QoS flow。
例如,FoV数据映射到第一QoS flow,non-FoV数据映射到第二QoS flow; 或FoV数据映射到QFI=1的QoS flow,non-FoV数据映射到QFI=2的QoS flow。
例如,按与视轴中心的角度将视频帧分为多个QoS flow:角度小的优先级高,映射到第一QoS flow或QFI=1的QoS flow;反之优先级低。
C12、接收核心网节点发送的GTP-U消息,所述GTP-U消息的头部携带所述第一信息;

可选地还需要说明的是,在所述根据所述第一信息,进行业务数据的传输处理之前,接入网节点需要先进行业务数据的映射,具体地实现过程为:
根据预设规则,将业务数据的QoS流映射至无线承载;
例如,此处的无线承载可以为数据无线承载(Data Radio Bearer,DRB),也就是说,接入网节点在进行传输处理之前,先将业务数据对应的QoS流映射至DRB。
具体需要说明的是,所述预设规则包括以下至少一项:
E11、基于所述第一信息将不同需求的QoS流映射到不同的无线承载上,其中,无线承载与无线链路控制(Radio Link Control,RLC)实体一一对应;

例如,一套传输路径对应一个DRB,基于第一信息将不同需求的QoS流映射到不同的DRB上,不同的DRB对应各自的RLC实体,接入网节点对不同的传输路径实现不同的无线传输策略。
以I帧和非I帧为例,I帧映射到QoS flow1,非I帧映射到QoS flow2,QoS flow1映射到DRB1所在的传输路径,QoS flow2映射到DRB2所在的传输路径,基站优先调度DRB1所在的传输路径上的数据。
