可选的，本申请所述的无线短距通信系统，可以是任意可能的短距通信系统，例如蓝牙，wifi、车载通用短距通信系统以及星闪等现在以及未来可能出现的短距通信系统。相比5G通信系统，短距通信系统的覆盖范围较小，且通信距离较短，本申请不具体限定短距通信系统的具体通信距离或覆盖范围，以相对5G通信系统的通信距离较短为准。

本申请实施例中涉及的各个功能或设备也可以称之为通信装置，其可以是一个通用设备或者是一个专用设备，本申请实施例对此不作具体限定。
如上介绍了本申请实施例涉及的应用架构，下面介绍本申请实施例的技术特征。
目前融合后的通信系统在通信传输过程中，核心网提供的服务经常无法满足不支持NAS信令传输的终端的需求。鉴于此，本申请实施例提供一种通信方法，使得核心网提供的服务更好的适用于不支持NAS信令传输的终端的需求。其中，方法和装置是基于同一技术构思的，由于方法及设备解决问题的原理相似，因此设备与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例提供第一种通信方法，请参见图3，为该方法的流程图。
S300、第一节点向第二节点发送第一信息，该第一信息用于请求建立第一协议数据单元(Protocol Data Unit，PDU)会话(session)。
可选的，该第一信息可以为第一PDU会话建立请求。
具体地，本申请实施例中该第一信息可以包括服务质量(Quality of Service，QoS)参数、应用类型、终端类型、预置共享密钥(pre share key，PSK)类型、数据网络名称(data network name，DNN)中的一种或多种会话参数。
其中，本申请实施例中的该QoS参数可以为5G融合的QoS参数，包括编码、端口号、优先级、时延、丢包率、吞吐率、保障比特率(Guard Bit Rate，GBR)、非保障比特率(Non Guard Bit Rate，NGBR)、最大流比特率(Maximum Flow Bit Rate，MFBR)、分配与保留优先级(Allocation and retention priority，ARP)、第五代通信系统核心网(he Fifth Generation Communication System Core，5GC)通知控制(QoS不满足要求时通知5GC)、短距通知控制(QoS不满足时通知对端节点)中的一个或多个。
该DNN用于指示所述第一PDU会话的类型。例如，该会话类型为网页浏览；或者，该会话类型为微信服务；或者该会话类型为支付宝服务等。
该应用类型用于指示所述第一PDU会话用于传输或者承载的业务类型。例如。该应用类型指示该第一PDU会话承载的业务类型为音频流业务、视频流业务或周期非周期业务等；或者，该应用类型指示该第一PDU会话用于传输的时延要求、可靠性要求、吞吐率要求等。
该终端类型用于指示该第一PDU会话的终端情况，例如，该终端类型为5G融合终端。
该PSK类型用于确定该第一PDU会话采用的白名单过滤机制。例如，该PSK类型为5G可信PSK。可以理解的，当该第一节点的PSK类型为5G可信PSK时，可以认为该第一节点在白名单中；当该第一节点的PSK类型为5G不可信PSK时，可以认为该第一节点不在白名单中。
需要说明的是，本申请实施例中白名单过滤机制包括但不限于终端类型、PSK类型。
其中，本申请实施例中该第二节点基于第一通信技术与该第一节点进行通信。
可以理解的，由于本申请中该通信系统可以为第一通信系统与第二通信系统融合后的通信系统，该第一通信系统与该第二通信系统不相同。例如，本申请以无线短距通信系统(第一通信系统)与5G蜂窝网络通信系统(第二通信系统)融合后的通信系统为例进行介绍：
在该融合后的通信系统中，该第二节点可以基于第一通信技术与位于该无线短距通信系统的该第一节点进行通信。从而使支持无线短距通信的第一节点可以通过第二节点接入5G蜂窝网络通信系统，进一步使用5G网络提供的服务，实现了无线短距通信系统与5G蜂窝网络通信系统的交互工作，优势互补。
可以理解的是，在实施S300之前，该第一节点确定没有满足当前业务需求的PDU会话。
示例性的，该第一节点若确定有满足要求的PDU会话，例如该第一节点之前请求第二节点建立的PDU会话可以满足当前应用层的业务需求，并且此时该第二节点还没有通知该第一节点该PDU会话已经释放，则表示该PDU会话可用，因此，该第一节点无需向该第二节点发送该第一信息；反之，该第一节点若确定没有满足要求的PDU会话，则该第一节点向该第二节点发送第一信息。
S301、第二节点接收来自第一节点的第一信息。
其中，在该第二节点在S301中接收到来自该第一节点的第一信息之后，还可以基于该第一信息确定是否为该第一节点建立新的PDU会话。
具体地，该第二节点可以通过下述两个方面确定是否为该第一节点建立新的PDU会话：
第一方面：该第二节点可以判断该第一节点是否在白名单中，若该第二节点确定该第一节点在白名单中，则该第二节点可以确定为该第一节点建立新的PDU会话；若该第二节点确定该第一节点不在白名单中，则该第二节点可以确定不为该第一节点建立新的PDU会话。
示例性的，该第二节点可以通过接收到的该第一信息中的PSK类型确定该第一节点是否在白名单中，例如，当该PSK类型为5G可信PSK时，可以认为该第一节点在白名单中，则该第二节点可以确定为该第一节点建立新的PDU会话。
第二方面：该第二节点可以判断是否存在满足当前业务需求的PDU会话，若有，则该第二节点可以确定不为该第一节点建立新的PDU会话；若无，则该第二节点可以确定为该第一节点建立新的PDU会话。
需要说明的是，本申请实施例中该第二节点可以同时满足上述两个方面时，该第二节点确定建立新的PDU会话；或者，该第二节点满足上述任一方面时，该第二节点确定建立新的PDU会话，具体本申请实施例并不进行限定。
S302、第二节点向第一节点发送第二信息，该第二信息用于指示所述第一PDU会话的标识以及所述第一PDU会话对应的第一QoS配置策略。
其中，所述第一QoS配置策略包含所述第一PDU会话与所述第一信息中包括的至少一个会话参数的对应关系。
需要说明的是，本申请实施例中所述第一QoS配置策略包括所述第一PDU会话与所述至少一个会话参数的对应关系，并不是指所述第一QoS配置策略真正意义上的包括一个第一PDU会话与所述至少一个会话参数的对应关系，而是由于所述第一QoS配置策略是 与所述第一PDU会话关联的，且是根据所述第一信息建立的PDU会话，因此，可以理解为所述第一QoS配置策略可以包括所述第一PDU会话与所述第一信息中包括的至少一个会话参数的对应关系。
其中，本申请实施例中该第一QoS配置策略可以包括一种或多种映射关系，具体并不限于下述三种映射关系：
映射关系1：业务流标识(Service flow identification，QFI)与区分服务编码点(Differentiated Service Code Point，DSCP)的映射关系。
映射关系2：DSCP与XQI的映射关系。
映射关系3：XQI与QoS参数的映射关系。
需要说明的是，本申请实施例中的XQI可以为无线短距通信系统的业务质量标识，例如，可以将该XQI理解为5G蜂窝通信系统中的5G服务质量指示符(5G QoS Identifier，5QI)。
可选的，该第二信息可以是该第二节点自行确定的，或者，该第二信息是该第二节点根据接收到的来自该第三节点发送的第四信息确定的。
其中，该第四信息用于指示该第一PDU会话的第二QoS配置策略，该第二QoS配置策略包含5QI，或者，所述第二QoS配置策略用于指示5QI与QFI的映射关系。
需要说明的是，本申请实施例中所述第二QoS配置策略还用于指示5QI与其他会话参数的映射关系，或者其他会话参数之间的映射关系，具体并不限于业务流标识QFI与数据的区分服务编码点DSCP的映射关系，DSCP与业务质量标识XQI的映射关系，XQI与QoS参数的映射关系等。
此外，本申请实施例中的第二QoS配置策略可以是基于QoS流的配置策略，还可以是基于第一PDU会话的配置策略，还可以是基于无线接入承载(Radio Access Bearer，RAB)的配置策略等，本申请实施例在此并不进行限定。
其中，本申请实施例中该第二节点基于第二通信技术与该第三节点进行通信，该第三节点可以基于该第二通信接收为基于该第一通信技术的第一节点提供服务。
可以理解的，由于本申请中该通信系统可以为第一通信系统与第二通信系统融合后的通信系统，该第一通信系统与该第二通信系统不相同。例如，本申请以无线短距通信系统(第一通信系统)与5G蜂窝网络通信系统(第二通信系统)融合后的通信系统为例进行介绍：
在该融合后的通信系统中，该第二节点可以基于第二通信技术与位于该5G蜂窝网络通信系统的该第三节点进行通信。从而可以通过支持5G蜂窝网络通信的第三节点为支持无线短距通信的第一节点提供5G网络服务，实现了无线短距通信系统与5G蜂窝网络通信系统的交互工作，优势互补。
可选的，当第二信息是该第二节点根据接收到的来自该第三节点发送的第四信息确定的情况下，该第四信息可以通过非接入层(Non-Access Stratum，NAS)消息承载。
例如，该第二节点接收到来自该第三节点的NAS消息，该NAS消息中承载了该第四信息，从而可以使接收到该NAS消息的第二节点，基于该NAS消息承载的第四信息确定该第二信息。
进一步的，本申请实施例中该第三节点向第二节点发送第四信息之前，接收到了第一请求信息，该第一请求信息用于请求所述第一PDU会话的第二QoS配置策略。
其中，本申请实施例中该第一请求信息可以携带在接收到的来自该第二节点的注册请求中，或者，该第一请求信息是在接收到的来自该第二节点的注册请求之后获取的。
进一步的，本申请实施例中该第二信息还可以用于指示该第一节点的QoS短距控制策略。
其中，该第一节点的QoS短距控制策略可以包括DSCP与传输信道标识(Transmission channel Identifier，TCID)的映射关系；或DSCP和IPV6流标签，与TCID的映射关系。
示例性的，本申请以星闪短距QoS映射配置流程为例，第二节点可以基于信道映射配置消息给第一节点配置短距通信相关的QoS策略，例如，第二节点可以向第一节点发送IP流与传输信道的映射配置。其中，该映射配置可以是基于DSCP与TCID的映射；或基于DSCP和IPv6流标签与TCID的映射等，在此不进行限定。
然后，第一节点基于该QoS策略将原始IP数据流映射到对应的TCID上传输。此外，该第一节点在接收到来自第二节点发送的该IP流与传输信道的映射配置后，还可以向该第二节点发送该IP流与传输信道的映射配置确认。
其中，同一个TCID可以承载不同的PDU会话的数据。
可以理解的，当第一节点与第二节点针对IP进行传输的时候，可以基于DSCP和/或IPV6流标签确定IP数据包的优先级。然后，在IP数据包到传输信道TCID的映射的时候，可以参考该DSCP和/或IPV6流标签与TCID的映射关系，将IP数据映射到对应的TCID上。
需要说明的是，该第一节点的QoS短距控制策略中包括的DSCP与TCID的映射关系；或DSCP和IPV6流标签与TCID的映射关系可以不考虑PDU会话，即不同的PDU会话可以在同一个TCID上传输。
S303、第一节点接收来自所述第二节点发送的第二信息。
S304、第二节点向所述第一节点发送第三信息，所述第三信息用于指示所述第一PDU会话对应的数据路由策略。
具体地，该数据路由策略包含所述第一PDU会话的会话信息。所述会话信息可以理解为与所述第一PDU会话相关的信息。
可选的，所述数据路由策略可以包括一种或多种信息，所述会话信息具体并不限于下述4种信息中的一个或多个：
信息1：所述第一PDU会话中包括的QoS流数量。
信息2：所述第一PDU会话的映射方式。
可选的，当该数据路由策略包括的第一PDU会话的映射方式为网络之间互连的协议(Internet Protocol，IP)地址与PDU会话的映射关系时，该数据路由策略可以用于指示通过基于该第一节点的IP地址建立的第一PDU会话执行数据传输。
