为了便于更好地理解本申请实施例,下面先介绍以下技术背景。
RAN可以通过用户面向UPF公开RAN上的信息,比如:拥塞信息,QNC(GBR不能满足),数据速率。当需要向UPF发送RAN公开信息的情况下,一种实现的方式是,通过终端的服务质量(Quality of Service,QoS)流的上行数据包的GTP-U包头中进行携带,但是通过数据包的GTP-U包头携带信息的上报方式存在以下问题需要解决:
问题1:UPF目前不支持对通过用户面接收的信息进行响应(如ACK)。当信息在RAN与UPF间传送遗失的情况下,RAN不清楚,也不能支持重传。通过用户面通道传递信息的情况下,如何在保障信息的传递的可靠性的问题还需要解决。
对问题1:一种解决方式通过GTP-U消息来传递RAN公开的信息,比如GTP-U ECHO Request和GTP-U ECHO Response。
由于GTP-U是一个PDU Session为单位的管道。RAN公开的信息(比如:拥塞信息,QNC(GBR不能满足),UE速率)是QoS流为粒度的信息。
因此,还需要进一步解决通过GTP-U消息来传递RAN公开的信息时,如何指示QoS流的标识。即问题2
对问题2,一种解决的方式是GTP-U消息中携带QoS流的标识,用于让UPF理解接收的RAN公开的信息是所述QoS流的标识所指示的QoS流的相关信息(比如:拥塞信息,QNC(GBR不能满足),UE速率)。另一种解决方式是涉及QoS流粒度的GTP-U消息。
另外,GTP-U ECHO Response存在必选参数。在对RAN公开的信息进行响应时,必选参数指示的内容未必发生。这时,如何忽略必选参数的问题也需要解决。此为问题3。
GTP-U回声响应(Echo Response)中必选参数:
该消息应作为对接收到的Echo Request的响应发送。恢复信息元素中的重启计数器值不应被使用,即发送方应将其设置为零,接收方应忽略此值。由于向后兼容的原因,恢复信息元素是必须的。3GPP TS 23.007和3GPP TS 23.527中规定了对恢复时间戳的处理。可选的私有扩展包含供应商或运营商的特定信息。其中,回声响应中的信息元素可以如表1所示。
表1回声响应中的信息元素
对问题1:另一种解决方式是通过下行数据包携带ACK信息进行确认接收到了所述RAN公开的信息,但当需要响应时,如果不存在下行数据包,,如何传递所述响应信息也需要解决,此为问题4。
