报文传输方法、装置、计算机设备和存储介质 技术领域
本申请涉及移动通信技术领域，特别是涉及一种报文传输方法、装置、计算机设备和存储介质。
背景技术
在5G通信技术领域，SDAP(Service Data Adaptation Protocol，服务数据适配协议)属于一种新的通信协议，其一端对接PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)、一端对接GTP(GPRS Tunneling Protocol，GPRS隧道协议)协议，分别承载了数据传输的无线侧、有线侧的收发处理。
在用户面数据处理中，SDAP模块大致工作内容为，根据GTP协议头携带的QoS(Quality of Service，服务质量QoS)信息，映射相应的SDAP实体和RB(Radio Bearer，无线承载)实体信息，从而完成了从QoS流到RAB承载的映射，并根据映射的QoS规则对终端的所有IP业务流进行传输。
但是，对于部分特定IP业务流，其传输质量较低。

具体实施方式
本申请提供的一种报文传输方法，可以应用于如图1所示的应用环境中，其中，5G核心网中包括核心网设备，5G接入网中包括5G基站和4G基站，用户终端设备与基站进行数据交互。其中，该用户终端可以但不限于是各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备。该应用环境中，用户终端设备通过5G接入网将各业务数据发送至5G核心网，其中，5G接入网与5G核心网之间进行数据交互时实现本申请提供的报文传输方法，其中5G基站中包括服务数据适配协议(Service Data Adaptation Protocol，SDAP)模块和分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)模块，其中，在实际应用中基站中的SDAP模块中设置了反射控制单元，该反射控制单元用于执行本申请提供的数据传输方法。
本申请实施例提供一种报文传输方法、装置、计算机设备和存储介质，下面将通过实施例并结合附图具体地对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。需要说明的是，本申请提供的一种报文传输方法，图2-图4的执行主体为反射控制单元，其中，其执行主体还可以是基站，其中该反射控制单元可以通过软件、硬件或者软硬件结合的方式实现成为基站的部分或者全部。
在一个实施例中，图2提供了一种报文传输方法，本实施例涉及的是反射控制单 元在接收到核心网设备发送的第一报文后，根据该第一报文中携带的IP(Internet Protocol，互联网协议地址)地址，调整该报文传输优先级的具体过程，如图2所示，所述方法包括：
S101，接收核心网设备发送的第一报文；第一报文中携带第一终端侧IP地址和第一QoS信息。
本实施例中，核心网设备表示的是5G核心网侧的设备，例如，5G核心网设备包括实现接入及移动性管理功能(Access and Mobility Management Function，AMF)和用户面功能(User Plane Function，UPF)的设备。其中，第一报文表示的是核心网设备发送给5G接入网中SDAP模块的报文，这里的第一只是用于与后面实施例中5G接入网中(基站中)SDAP模块接收的PDCP模块发送的第二报文进行区分，不是限定报文顺序以及报文序号的，需要说明的是，本申请实施例中所有的第一、第二等作用均是用于区分，例如第一终端侧IP地址、后文的第二终端侧IP地址和第一QoS信息，以及后文的第二QoS信息，也只是为了区分，另外本实施例中的第一报文、第二报文在又有些情况下可以指代同一个报文，也可以指代不同报文，相应地，终端侧IP地址和QoS信息的情况也相同，本实施例后续不再赘述。
具体地，在实际应用中，基站的SDAP模块中的反射控制单元接收到核心网设备发送过来的第一报文，其中该第一报文可以是GPRS隧道协议(GPRS Tunneling Protocol，GTP)报文，该第一报文中携带第一终端侧IP地址和第一QoS信息，其中，QoS信息中包括了该第一报文的流分类、流量监管、流量整形、接口限速、拥塞管理、拥塞避免的相关信息，例如可以从该第一QoS信息得到报文的SDAP实体和无线承载(Radio Bearer，RB)，以及各RB的优先级等，本实施例对此不做限定。
S102，若第一终端侧IP地址为预先约定的IP地址，根据第一QoS信息判断第一报文的当前RB的优先级是否为最高优先级。
其中，本申请实施例针对的是特定IP业务流传输质量的改善，因此，在接收到第一报文后，需要先判断该第一报文是否为特定IP业务流，即判断该第一报文中携带的第一终端侧IP地址是否为预先约定的IP地址，只有在该第一报文是预先约定的IP地址，反射控制单元才会对其传输优先级进行控制。
具体地，基于上述S101接收的第一报文，若该第一报文中的第一终端侧IP地址为预先约定的IP地址，反射控制单元从该第一报文中携带的第一QoS信息查找当前的 RB，并判断当前的RB的优先级是否为最高优先级，例如若第一QoS信息中存储了各RB对应的优先级等级，则反射控制单元可以直接判断出RB的优先级是否为最高优先级；若第一QoS信息中各RB优先级是以顺序存储的，则反射控制单元根据各RB的顺序判断当前RB的优先级是否为最高优先级，本实施例对此不做具体限定。在得到判断结果之后，若判断结果为当前RB的优先级是最高优先级，则执行S103步骤，若判断结果为当前RB的优先级不是最高优先级，则执行S104步骤。
需要说明的是，在当前RB的优先级不是最高优先级之前，反射控制单元还需要先判断该第一报文当前是否有多个RB，如果只有一个RB，无需进行后续步骤，直接第一报文的当前SDAP实体发送第一处理指令即可，若该第一报文具有多个RB的情况下，才判断当前的RB的优先级是不是最高优先级。
S103，若当前RB的优先级是最高优先级，向第一报文的当前SDAP实体发送第一处理指令，第一处理指令用于指示对第一报文进行封装处理后发送至PDCP模块。
本步骤为上述判断结果为当前RB的优先级是最高优先级的情况，该情况下，反射控制单元第一报文的当前SDAP实体发送第一处理指令，其中，第一处理指令用于指示对第一报文进行封装处理后发送至PDCP模块。其中，第一报文的当前SDAP实体为反射控制单元从第一QoS信息中获取的。其中，示例地，当前SDAP实体接收到第一处理指令后，对第一报文进行封装处理为封装SDAP头部信息，并将封装后的第一报文以SDAP PDU会话发送至PDCP模块。
S104，若当前RB的优先级不是最高优先级，根据第一QoS信息选择新的SDAP实体，并向新的SDAP实体发送第一处理指令；新的SDAP实体表示优先级最高的RB对应的SDAP实体。
本步骤为上述判断结果为当前RB的优先级不是最高优先级，该情况下，反射控制单元需要从上述第一报文携带第一QoS信息中重新选择新的SDAP实体，其中，选择的新的SDAP实体表示优先级最高的RB对应的SDAP实体，相当于，当第一报文当前不是以最高优先级传输时，就要控制该第一报文是以最高优先级进行传输的。具体地，反射控制单元根据第一QoS信息选择新的SDAP实体后，向该新的SDAP实体发送第一处理指令，则该新的SDAP实体接收到该第一处理指令后，对第一报文进行封装处理为封装SDAP头部信息，并将封装后的第一报文以SDAP PDU会话发送至PDCP模块。
本实施例提供的报文传输方法，在报文的IP地址是预先约定的IP地址时，反射控制单元判断该报文在当前RB的优先级是最高优先级的情况下，控制该报文当前的SDAP实体封装处理并发送该报文，在该报文的当前RB的优先级不是最高优先级的情况下，重新根据优先级最高的RB确定新的SDAP实体，并控制该新的实体封装处理发送该报文，该方法中，在接收到报文是约定好的IP报文时，无论什么情况，均可以保证该报文是优先级最高的RB进行传输，即对于约定服务业务的IP流，在无线传输中，将其优先级提升至最高优先级的RB承载，大大提高了特定IP业务流的传输质量。
在上述根据第一处理指令对第一报文封装SDAP头部信息时，SDAP头部中的RQI(Reflective QoS Indication，反射QoS指示)字段根据SDAP实体的不同取值不同，针对此提供一个实施例，在一个实施例中，若第一处理指令被发送至第一报文的当前SDAP实体，则封装处理后的第一报文的SDAP头部信息中RQI字段为第一值；若第一处理指令被发送至新的SDAP实体，则封装处理后的第一报文的SDAP头部信息中RQI字段为第二值；其中，第一值和第二值为不同的值。
其中，不同的SDAP实体进行封装处理后SDAP头部中的RQI字段取值不同，例如，若是当前的SDAP实体对该第一报文封装SDAP头部信息，则RQI字段置0，若是选择的新的SDAP实体对该第一报文封装SDAP头部信息，则RQI字段置1，这样下游协议接收到该第一报文后，可根据RQI的值对是否更换了SDAP实体进行区分。
上述实施例中，反射控制单元根据第一QoS信息判断第一报文的当前RB的优先级是否为最高优先级的前提是需要确定接收的第一报文中携带的第一终端侧IP地址属于预先约定的IP地址，但对于第一报文中携带的第一终端侧IP地址不属于预先约定的IP地址的情况，本申请也提供了一种实施例，则在一个实施例中，该方法包括：若第一终端侧IP地址不是预先约定的IP地址，向第一报文的当前SDAP实体发送第一处理指令。该实施例中当反射控制单元判断到第一报文中携带的第一终端侧IP地址不属于预先约定的IP地址时，即该第一报文不是预先约定报文，表示反射控制单元不会对其承载优先级进行控制，所以反射控制单元直接向该第一报文的当前SDAP实体发送第一处理指令即可，让当前SDAP实体去封装处理该第一报文，并将处理后的第一报文发送至PDCP模块中，这样，在接收到的第一报文不是约定报文的情况下，无需控制其无线承载优先级最高，节省了处理资源。
上述实施例S104步骤中的在当前RB的优先级不是最高优先级时，反射控制单元 需要根据第一QoS信息选择新的SDAP实体，对于反射控制单元选择新的SDAP实体的具体过程，本申请提供了一种实施例，则在一个实施例中，如图3所示，上述S104步骤中“根据第一QoS信息选择新的SDAP实体”包括：
S201，根据第一QoS信息，获取第一报文的当前SDAP实体和第一报文的RB信息；第一报文的RB信息中包括第一报文的当前RB、除当前RB以外的其他RB、当前RB和其他RB的优先级标识。
本实施例中，第一报文中携带了第一QoS信息，反射控制单元从该第一QoS信息中获取第一报文的当前SDAP实体和第一报文的RB信息，其中，一个报文可以对应多个RB，则第一报文的RB信息中包括了第一报文的当前RB、除当前RB以外的其他RB以及所有RB的优先级标识，其中，所有RB的优先级标识可以是文字、字母、数字或者各种组合形式标识，本实施例对此不做限定。
S202，根据优先级标识，从其他RB中选择最高优先级的RB。
由于本实施例是当前RB的优先级不是最高优先级的情况，所以基于上述S201步骤中获取的RB的优先级标识，反射控制单元从其他RB中选择最高优先级的RB，要保证第一报文的承载的优先级最高。
S203，将最高优先级的RB对应的QoS流的SDAP实体，确定为新的SDAP实体。
基于上述S202步骤中选择的最高优先级的RB，反射控制单元将该最高优先级RB对应的SDAP实体，确定为新的SDAP实体，具体地，反射控制单元选择最高优先级RB对应任一QoS流，该任一QoS流的SDAP实体即为最高优先级的RB对应的SDAP实体。
本实施例提供的报文传输方法，反射控制单元根据第一报文携带的第一QoS信息，选择出最高优先级的RB，并将该最高优先级的RB对应的SDAP实体确定为新的SDAP实体，这样将第一报文的承载控制为最高优先级，并控制最高优先级承载对应的SDAP实体处理该第一报文，提高了该第一报文的传输质量。
在反射控制单元根据第一QoS信息选择新的SDAP实体之后，相当于将新的SDAP是替换了第一报文的当前的SDAP实体，那么这种情况下，第一报文被替换的当前SDAP实体就变成了SDAP的原SDAP实体，则在一个实施例中，该方法还包括：将第一报文的当前SDAP实体确定为第一报文的原SDAP实体，并进行存储。
本实施例中对第一报文的SDAP实体更换了新的SDAP，则其当前的SDAP实体变成了原SDAP实体，反射控制单元需要将该原SDAP实体进行存储，以记录该第一报文SD AP实体的更换记录，方便后续查询。
上述所有实施例是基于报文流向为5G核心网设备到5G接入网的SDAP模块再到5G接入网的PDCP模块的流向，属于下行数据传输过程，针对所有下行数据传输过程的实施例，本申请提供一种完整的实施例，则如图3a所示，该完整的实施例包括：
S11，接收来自核心网设备的报文，转S12；
S12，剔除基站的IP/UDP(User Datagram Protocol，用户数据报协议)/GTP头部开销，转S13；
S13，根据GTP头中携带的QoS信息查找当前SDAP实体及其RB信息，转S14；
S14，判断该报文源IP是否为约定服务器IP地址，若是转S15，否则转S19；
S15，判断是否存在多个RB，若是转S16，否则转S19；
S17，选择最高优先级RB对应任一QoS流，将该任一QoS流的SDAP实体确定为新的SDAP实体，并记录QoS信息所查当前SDAP实体，转S18；
S18，所选新的SDAP实体处理所述报文，即,封装SDAP头部且RQI字段置1，转S10；
S19，QoS信息所查的当前SDAP实体处理所述报文，即,封装SDAP头部且S10，将处理后的报文以SDAP PDU(Protocol Data Unit，协议数据单元)发往相应的PDCP模块。
本实施例提供的报文传输方法，其仅涉及基站内部的深度处理优化，具体优化前后的对比可参见图3b所示，本实施例中具体实施过程与上述所有实施例过程相同，在此不再赘述，由于本实施例所有步骤的执行主体为设置在SDAP模块中的反射控制单元，该反射控制单元专门负责将约定服务业务的IP流，在无线传输中，优先级提升至最高优先级的RB承载，且全过程在基站中执行，即以基站视角主动地最大程度地保障特定服务的客户体验。
另外，在实际应用中还存在上行数据传输过程，即5G接入网的PDCP模块到5G接入网的SDAP模块再到5G核心网设备的流向，对于部分内容与上述上行数据传输过程实施例中的内容重复，因此对于重复的内容将不再赘述。该流向过程本申请提供了一个实施例，如图4所示，该方法还包括：
S301，接收PDCP模块发送的第二报文；第二报文中携带第二终端侧IP地址。
本实施例中，5G接入网SDAP模块中的反射控制单元接收PDCP模块发送的第二报 文，这里的第二报文在S101步骤中已经进行了说明，其不是对报文顺序或者序号等进行限定，只是与第一报文作以区分。其中，该第二报文中携带了第二终端侧IP地址。
S302，若第二终端侧IP地址为预先约定的IP地址，检测第二报文是否存在第二报文的原SDAP实体。
基于上述S301步骤中接收的第二报文，反射控制单元在第二报文中第二终端侧IP地址为预先约定的IP地址，检测第二报文是否存在第二报文的原SDAP实体，本步骤是在第二报文中第二终端侧IP地址为预先约定的IP地址的情况下执行的，因此，反射控制单元在接收到第二报文后需要先判断第二终端侧IP地址是否为预先约定的IP地址，只有在确定第二终端侧IP地址为预先约定的IP地址的情况下才执行本步骤。
具体地，第二报文的原SDAP实体表示的是要查询该报文是否被更换过SDAP实体，即被调整过无线承载，发射控制单元检测时在内存中查询，若该第二报文在下行过程中被更换过SDAP实体，即在内存中存储过SDAP实体，则反射控制单元在内存中就可以查找到该第二报文有原SDAP实体，否则就查询不到，即该第二报文不存在原SDAP实体。可选地，由于在下行过程中对于更换过SDAP实体的报文，其头部信息中RQI字段为1，可根据该字段在报文上行过程中对应给出其他标识，这样反射控制单元还可以根据该其他标识判断该报文是否被更换过SDAP实体。在检测后若检测结果为第二报文存在原SDAP实体，则执行S303步骤，若检测结果为第二报文不存在原SDAP实体，则执行S304步骤。
S303，若第二报文存在第二报文的原SDAP实体，发送第二处理指令给第二报文的原SDAP实体，第二处理指令用于指示对第二报文封装处理后发往核心网设备。
本步骤为第二报文存在原SDAP实体的情况，表示该第二报文被更换过无线承载，需要原SDAP实体处理该第二报文，则该情况下反射控制单元发送第二处理指令给原SDAP实体，其中，该第二处理指令用于指示对原SDAP实体将该第二报文封装处理后发往核心网设备，其中进行封装处理表示对该第二报文封装相关的协议头部信息，例如GTP等，则可选地，根据第二处理指令对第二报文封装处理后，上述封装处理后的第二报文包括基站侧GTP、UDP、IP头部信息，其中GTP头部信息中包括第二报文的第二QoS信息。即根据第二处理指令的第二报文中封装了基站侧的GTP、UDP、IP头部信息，且GTP头部信息中包括第二报文的第二QoS信息。
S304，若第二报文不存在第二报文的原SDAP实体，发送第二处理指令给第二报文 的当前SDAP实体。
本步骤为第二报文不存在其原SDAP实体的情况，表示该第二报文没有被更换过无线承载，直接当前SDAP实体处理该第二报文即可，则该情况下反射控制单元发送第二处理指令给第二报文的当前SDAP实体，以使第二报文的当前SDAP实体对第二报文封装处理后发往核心网设备。
本实施例提供的报文传输方法，在反射控制单元接收到PDCP模块发送的第报文后，在该第二报文中携带的第二终端侧IP地址是预先预定的IP地址时，查找该第二报文是否存在第二报文的原SDAP实体，若存在则指示原SDAP实体对第二报文进行封装发送处理，若不存在才指示当前SDAP实体对第二报文进行封装发送处理，这样，使得发送给核心网设备的报文是最初的SDAP实体处理的，保证了报文传输过程中处理痕迹对“核心网”设备并不可见，更平滑、更低成本地实现QoS重映射的落地。
反射控制单元在接收第二报文后，会判断第二报文中携带的第二终端侧IP地址是否属于预先约定的IP地址，对于第二报文中携带的第二终端侧IP地址不属于预先约定的IP地址的情况，本申请也提供了一种实施例，在一个实施例中，该方法包括：若第二报文中携带的第二终端侧IP地址不是预先约定的IP地址，则发送第二处理指令给第二报文的当前SDAP实体。
该实施例中当反射控制单元判断到第二报文中携带的第二终端侧IP地址不属于预先约定的IP地址时，即该第二报文不是预先约定报文，表示反射控制单元不会对该第二报文进行控制，所以反射控制单元直接向该第二报文的当前SDAP实体发送第二处理指令即可，让当前SDAP实体去封装处理该第二报文，并将处理后的第二报文发送至核心网设备，这样，在接收到的第二报文不是约定报文的情况下，无需控制查找其是否存在原SDAP实体，节省了处理资源。
针对所有上行数据传输过程的实施例，本申请提供一种完整的实施例，则如图4a所示，该完整的实施例包括：
S21，接收来自PDCP的报文，转S22；
S22，剔除SDAP头部开销，转S23；
S23，判断报文目标IP是否为约定服务器IP地址，若是转S24，否则转S26；
S24，查找该报文是否存在原SDAP实体，若是转S25，否则转S26；
S25，原SDAP实体处理报文，封装相应的Gtp头,含QoS信息，转S27；
S26，当前SDAP实体处理报文，封装相应的Gtp头,含QoS信息，转S27；
S27，将上述报文进一步封装UDP/IP头,发往核心网设备。
本实施例中具体实施过程与上述图4实施例中相同，在此不再赘述，可以理解的是，本实施例的所有步骤的执行主体也为SDAP模块中的反射控制单元。本实施例在将报文发往核心网设备前将报文的还原到原RB承载的SDAP实体进行处理，整个处理过程在5G基站中进行，对“核心网”设备并不可见，使得更平滑、更低成本地实现QoS重映射的落地。
应该理解的是，虽然图2-4的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图2-4中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
在一个实施例中，如图5所示，提供了一种报文传输装置，包括：第一接收模块10、判断模块11、第一处理模块12和第二处理模块13，其中，
