Description

一种数据传输的方法以及相关装置

技术领域
本申请实施例涉及通信技术领域，具体涉及数据传输。
背景技术
第五代(5th Generation，5G)的(Release16，R16)版本引入了时间敏感网络(Time Sensitive Network，TSN)的时间敏感通信(Time Sensitive Communication，TSC)，以使5G支持精确时间控制的工业自动化制造应用。
而在第三代合作项目(3rd generation partnership project，3GPP)的IMS(IP Multimedia Subsystem，IP多媒体子系统)协议中用户终端(User Equipment，UE)与UE之间的业务通信是需要通过将UE注册到IMS系统的S-CSCF(Serving Call Session Control Function，服务呼叫会议控制功能)中，通过S-CSCF的协作来完成UE与UE之间的通信。然而，在目前的R16版本的TSN中只是定义了由DN(Data Network，数据网络)ES(End Station，终端站设备)来发起通信建立起UE ES与DN ES的TSN通信，但TSC至少要支持UE与UE之间的通信。
TSC数据在3GPP网络中是基于服务质量(Quality of Service，QoS)流(Flow)来传输的。

5G系统的R16标准中引入了TSC(Time Sentive Communication，时间敏感通信)，这使得5G系统能够支持精确时间控制的工业自动化制造应用。按照5G系统的R16标准的指引，5G系统可作为TSN的一个Ethernet Bridge(以太网桥接器)而被整合到TSN中，整合后的系统可被称作TSN通信系统。图1示出了本申请一个示例性实施例提供的一种TSN通信系统的结构示意图；如图所示，该TSN通信系统包括TSN和5G系统。
其中，5G系统包括UE(User Equipment，用户终端)及各种功能实体设备；这些功能实体设备主要包括：①UPF(User Plane Function，用户面功能设备)；②NG RAN(NG Radio Access Network，5G无线接入网功能设备)，其中NG接口是无线接入网与5G核心网之间的接口。③AMF(Access and Mobility Management Function，接入和移动管理功能设备)，负责移动性管理，与UE和NG RAN相连接。④SMF(Session Management Function，会话管理功能设备)，负责会话管理，与AMF和UPF相连接。⑤PCF(Policy Control Function，策略控制功能设备)，负责策略控制，并与SMF相连。⑥UDM(Unified Data Manager，统一数据管理设备)，用于对业务数据进行统一管理。⑦AF(Application Function，应用功能设备)，用于提供业务数据。TSN包括ES(End Station，终端站设备)和CNC(Centralized Network Controller，集中网络控制器)，该CNC用于对整个TSN通信系统的业务进行统一管理。如图1所示，5G系统中的UE通过DS-TT(Device Side TSN Translator，设备侧TSN转换器)与5G系统外部的TSN DN(Data Network，数据网络)中的一个或多个ES相连。UPF通过NW-TT(NetWork TSN Translator，网络TSN转换器)与TSN DN中的一个或多个ES相连。其中，DS-TT及NW-TT均可提供用于进行数据传输的Port(端口)。
在TSN中，UE与时间敏感通信设备侧例如设备侧TSN转换器(Device-side TSN translator，DS-TT)都属于设备侧桥(Device side of Bridge)，该设备侧桥与时间敏感通信系统(TSN System)连接。UPF网元中包括时间敏感通信网络侧(NetWork TSN translator，NW-TT)。
为了实现对TSN网络的这种透明性，以及5GS(5G系统)作为任何其他TSN桥的外观，5GS通过DS-TT和NW-TT提供TSN进入和输出端口。DS-TT和NW-TT可选地支持以下功能：
保持和转发功能，以消除抖动；
链路层连接性发现和报告。
UE可以包括：手持终端、笔记本电脑、用户单元(Subscriber Unit)、蜂窝电话(Cellular Phone)、智能电话(Smart Phone)、无线数据卡、个人数字助理(Personal Digital Assistant，PDA)电脑、平板型电脑、无线调制解调器(Modem)、手持设备(Handheld)、膝上型电脑(Laptop Computer)、无绳电话(Cordless Phone)或者无线本地环路(Wireless Local Loop，WLL)台、机器类型通信(Machine Type Communication，MTC)终端或是其他可以接入网络的设备。UE与接入网设备之间采用某种空口技术相互通信。
上述图1所示的网元中，UE会发送上行数据，UPF会发送下行数据，无论是UE发送上行数据，还是UPF会发送下行数据，在发送的数据是TSC数据时，都需要将该TSC数据映射到QoS流上进行传输。
应理解的是，在本申请实施例中的第一网络设备由AF和CNC构成。为便于更好地理解本申请实施例所提出的方案，下面对本实施例中的具体流程进行介绍，如图2所示，是本实施例提供的一种数据传输的方法，该方法可以包括：
201、第一UE向第一网络设备发送TSC通信请求。
本实施例中，TSC通信请求可以由第一UE依次通过第一AMF、第一SMF以及第一PCF透明地传输到该第一网络设备。TSC通信请求携带了第一TSC会话需求参数，其中，TSC通信请求中增加了TSC会话需求容器(TSC Session Requirement Container)，该第一TSC会话需求参数是包含于TSC会话需求容器中的参数，例如，该第一TSC会话需求参数可以包括第二UE的标识和TSC流的QoS需求(TSC stream QoS Requirements)，又如，该TSC会话中TSC流的QoS需求可以包括第一UE与第二UE之间端到端的时延信息、数据的周期性、数据的最后到达时间(Burst Arrival Time)等。当然了，在实际应用中，该第一TSC会话需求参数还可以包括应用标识(Application ID)等，一个TSC会话中可能包含有多个TSC会话流，每个TSC会话流的操作过程都是类似的。
需要说明的是，上述所描述的TSC会话的QoS需求是第一UE在TSN时钟域上建立起的TSC的业务需求，例如：第一UE传输业务数据到第二UE之间所需要的传输总时延等。
另外，需要说明的一点是，由于第一网络设备可以由AF和CNC组成。因此，对于该TSC通信请求还可以由第一PCF透明地传输到AF，由AF将该CNC通信请求透明地传输到CNC中。
可选地，在一些实施例中，上述所描述的TSC通信请求可以包括PDU会话修改请求或PDU会话建立请求，在本申请实施例中将不做具体限定。
202、第一网络设备根据第一TSC会话需求参数确定第一业务流的QoS需求、第二业务流的QoS需求、第一信息和第二信息。
实际上，第一信息可以包括第一UE的TSCAI信息以及第一UE的TSC端口管理信息(TSN Port Management Information)，第二信息可以包括第二UE的TSCAI信息以及第二UE的TSC端口管理信息。所描述的TSCAI(TSCAssistance Information，时间敏感通信辅助信息)信息实际上是数据流的信息，如前所述，5G系统的R16标准中引入TSC的目的在于使得5G系统能够支持精确时间的工业自动化制造应用，而TSCAI信息能够帮助对数据流进行精确的时间控制。因此，在第一网络设备根据第一TSC会话需求参数确定出第一信息、第二信息后，可以将其分别发送给第一UE所对应的第一PCF和第二UE所对应的第二PCF，使得第一PCF进一步地通过第一SMF、第一AMF将该第一信息传输给该第一 UE对应的NG RAN网元，从而使得NG RAN网元可以根据该第一信息中的TSCAI信息对数据流进行精确的时间控制；同理，使得第二PCF进一步地通过第二SMF、第二AMF将该第二信息传输给该第二UE对应的NG RAN网元，从而使得NG RAN网元可以根据该第二信息中的TSCAI信息对数据流进行精确的时间控制。下述是关于TSCAI的一些说明，具体如下：
TSCAI描述了用于5G系统的TSC流量特征。TSN流量模式的知识对于gNB(5G基站)是有用的，以允许gNB通过配置授权、半持久调度或动态授权更有效地调度周期性、确定性的业务流。TSCAI信息的定义可参见下述表一，其中，TSCAI信息由第一AMF和第二AMF分别提供给各自相应的NG RAN网元，例如：第一SMF和第二SMF在建立QoS Flow的过程中将TSCAI信息分别传输给相应的第一AMF和第二AMF后，使得第一AMF和第二AMF提供给各自的NG RAN网元。
表一：TSCAI信息
Figure PCTCN2020121743-appb-000001
上表包括TSC业务数据的突发到达时间(Burst Arrival Time)，以及业务数据的周期性(Periodicity)。TSC业务数据是从Burst Arrival Time到达后，以Periodicity规定的时间一包一包的到达NG RAN网元。
还可以理解的是，上述所描述的TSCAI信息及QoS流的QoS参数是在5G时钟域上的，而第一业务流的QoS需求、第二业务流的QoS需求实际上是第一网络设备所在的TSN时钟域上为第一UE和第二UE重新分配的QoS需求。也就是说由于第一网络设备所接收到的TSC会话的QoS需求是在TSN时钟域上建立的，是端到端的QoS需求，需要分解为第一UE与第二UE相关的需求，从而实现总的端到端的QoS需求。另外，第一网络设备往往根据网络的配置，需要将该TSN时钟域上的TSC会话的QoS需求根据配置作调整，从而更新并生成第二TSC会话的QoS需求，从而依据第二TSC会话的QoS需求来重新得到上述所描述的第一业务流的QoS需求、第二业务流的QoS需求。例如，假设上述所接收到的TSC会话的QoS需求中的时延是第一UE到第二UE之间的端到端的总传输时延为2000微秒，而第一网络设备根据网络的配置，需要将该TSN时钟域上的TSC会话的QoS需求中的2000微秒的时延更新为1800微秒。然后依据更新后的第二TSC会话QoS需求中的1800微秒，确定出第一UE和第二UE等分地分配的QoS需求为800微秒，如：1800/2＝900, 900微秒减去一些其它的100微秒时延得到800微秒，即第一业务流的QoS需求、第二业务流的QoS需求均为800微秒等，在实际应用中，还可以是其他的重新分配方式，本申请实施例中将不做具体限定。
需要说明的是，上述所描述的更新后的TSC会话的QoS需求中的时延是可以计算出用于第一UE的第一业务流的QoS需求和用于第二UE的第二业务流的QoS需求。具体可以参照图3中步骤303进行理解，此处不做赘述。
203、所述第一网络设备向第一UE对应的第一PCF发送所述第一业务流的QoS需求和第一信息，以及根据所述第二UE的标识向第二UE对应的第二PCF发送所述第二业务流的QoS需求和第二信息。
本实施例中，第一网络设备分别给第一UE和第二UE所在的5G网络提供业务流的QoS需求。第一网络设备会向第一UE对应的第一PCF发送该第一业务流的QoS需求以及向第二UE对应的第二PCF发送该第二业务流的QoS需求。
需要说明的是，上述所描述的第一PCF和第二PCF是不相同的网元。
可选地，在另一些实施例中，第一网络设备向所述第一UE对应的第一PCF发送所述第一业务流的QoS需求和所述第一信息之前，还需要根据第一UE的标识来确定第一PCF，以便于为后续的信令传输提供正确的节点，建立起信令传输路径。同理，在另一些实施例中，第一网络设备根据所述第二UE的标识向所述第二UE对应的第二PCF发送所述第二业务流的QoS需求和所述第二信息时，可以先根据第二UE的标识来确定第二PCF，以便于为后续的信令传输提供正确的节点，建立起信令传输路径。进而向第二PCF发送第二业务流的QoS需求和第二信息。
由于CNC可以在接收了由AF发送的第一TSC会话需求参数后根据该第一TSC会话需求参数确定出第一业务流的QoS需求、第一信息、以及第二业务流的QoS需求、第二信息。然后将第一业务流的QoS需求、第一信息、以及第二业务流的QoS需求、第二信息发送给AF，那么此时AF在接收了第一业务流的QoS需求、第一信息、以及第二业务流的QoS需求、第二信息后，就可以通过第一UE的标识来确定第一PCF，以及通过第二UE的标识来确定第二PCF。
204、第一PCF将第一业务流的QoS需求映射为第一业务流的QoS策略。
本实施例中，由于5G通信系统是依据业务流的QoS需求来设置QoS流的，而第一PCF是负责第一UE的策略控制，因此在接收到第一网络设备发送的第一业务流的QoS需求后，便可以将该第一业务流的QoS需求映射成第一业务流的QoS策略。这样，便可以将该第一业务流的QoS策略发送给相应的第一SMF，从而使得第一SMF根据该第一业务流的QoS策略将第一业务流映射到QoS流中，从而建立起传输所述第一UE的业务数据的第一QoS流。
205、第一PCF向第一SMF发送所述第一业务流的QoS策略和所述第一信息。
206、第一SMF根据所述第一业务流的QoS策略建立传输所述第一UE的业务数据的第一QoS流。
本实施例中，由于第一业务流的QoS策略包括了建立QoS流所应用到的QoS参数，所以第一SMF可以根据该第一业务流的QoS策略所包括的QoS参数来建立起传输该第一UE的业务数据的第一QoS流。当为第一UE建立起一个第一QoS流时，可以使用第一信息中的TSC端口管理信息为这个第一QoS流分配对应的DS-TT上的一个第一Port以及NW-TT上的一个第二Port，从而组成一个Port对。
可选地，在另一些实施例中，该第一信息包括前述所描述的第一UE的TSCAI信息，所以在第一SMF根据所述第一业务流的QoS策略建立传输所述第一UE的业务数据的第一QoS流之后，还包括将所述第一业务流的QoS策略、所述TSCAI信息映射到N2会话消息中，将所述第一业务流的QoS策略映射到所述N1会话消息中。
本实施例中，第一SMF可以将该第一业务流的QoS策略所包含的QoS参数映射到QoS配置(QoS Profile)，然后结合上述收到的第一信息中包含的TSCAI信息载入到N2会话消息，提供给第一UE所对应的5G基站gNB；另外，还需要将第一业务流的QoS策略所包含的QoS参数映射到QoS规则(QoS Rule)及收到的第一信息中包含的DS-TT端口配置信息，载入N1会话消息中，提供给第一UE。应当理解的是，由于上述所描述的TSCAI信息是基于TSN时钟域的参数值，所以第一SMF需要将其通过映射等形式转换到5G系统的时钟域值。
207、第二PCF根据所述第二业务流的QoS需求映射为第二业务流的QoS策略。
本实施例中，由于5G通信系统是依据业务流的QoS需求来设置QoS流的，而第二PCF是负责第二UE的策略控制，因此在接收到第二网络设备发送的第二业务流的QoS需求后，便可以将该第二业务流的QoS需求映射成第二业务流的QoS策略。这样，便可以将该第二业务流的QoS策略发送给相应的第二SMF，从而使得第二SMF根据该第二业务流的QoS策略将第二业务流映射到QoS流中，从而建立起传输所述第二UE的业务数据的第二QoS流。
208、第二PCF向第二SMF发送所述第二业务流的QoS策略和所述第二信息。
209、第二SMF根据所述第二业务流的QoS策略建立传输所述第二UE的业务数据的第二QoS流。
本实施例中，由于第二业务流的QoS策略包括了建立QoS流所应用到的QoS参数，所以第二SMF可以根据该第二业务流的QoS策略所包括的QoS参数来建立起传输该第二UE的业务数据的第二QoS流。当为第二UE建立起一个第二QoS流时，可以使用第二信息中的TSC端口管理信息为这个第二QoS流分配对应的DS-TT上的一个第一Port以及NW-TT上的一个第二Port，从而组成一个Port对。
可选地，在另一些实施例中，该第一信息包括前述所描述的第二UE的TSCAI信息，所以在第二SMF根据所述第二业务流的QoS策略建立传输所述第二UE的业务数据的第二QoS流之后，还包括将所述第二业务流的QoS策略、所述TSCAI信息映射到N2会话消息中，将所述第二业务流的QoS策略映射到所述N1会话消息中。
本实施例中，第二SMF可以该第二业务流的QoS策略所包含的QoS参数映射到QoS配置(QoS Profile)，然后结合上述收到的第二信息中包含的TSCAI信息载入到N2会话消息，提供给第二UE所对应的5G基站gNB；另外，还需要将第二业务流的QoS策略所包含的QoS参数映射到QoS规则(QoS Rule)后及收到的第二信息中包含的DS-TT端口配置信息，载入N1会话消息中，提供给第二UE。应当理解的是，由于上述所描述的TSCAI信息是基于TSN时钟域的参数值，所以第二SMF需要将其通过映射等形式转换到5G系统的时钟域值。
应该理解的是，上述步骤204-206与步骤207-209的执行顺序不做限定，在实际应用中，也可以先执行步骤207-209后执行步骤204-206，又或者步骤204-206与步骤207-209还可以同步执行，具体本申请实施例中将不做具体限定。
本申请实施例中，通过第一UE发起TSC通信请求，使得第一网络设备在确定第一业务流的QoS需求和第二业务流的QoS需求后分别提供给第一UE和第二UE所在的5G网络，从而分别触发建立起用于传输第一UE的业务数据的第一QoS流，及触发建立起用于传输第二UE的业务数据的第二QoS流，实现了由UE发起TSC通信请求来建立第一UE与第二UE之间的TSC传输通道。
为便于更好地理解本申请实施例所提出的方案，在上述图2所描述的实施例的基础上，下面对本实施例中的具体流程进行介绍，如图3所示，是本实施例提供的一种数据传输的方法，该方法可以包括：
301、第一UE向第一网络设备发送TSC通信请求。
本实施例中，TSC通信请求携带了第一TSC会话需求参数，其中，TSC通信请求中增加了TSC会话需求容器，该第一TSC会话需求参数是包含于TSC会话需求容器中的参数，例如，该第一TSC会话需求参数可以包括第二UE的标识和业务流的QoS需求(TSC stream QoS Requirements)，又如，该TSC会话的QoS需求可以包括第一UE与第二UE之间的延迟信息、数据的周期性、数据的最后到达时间(Burst Arrival Time)等。当然了，在实际应用中，该第一TSC会话需求参数还可以包括应用ID等。
需要说明的是，上述所描述的TSC会话的QoS需求是第一UE在TSN时钟域上建立起的TSC的业务需求。
可选地，在一些实施例中，上述所描述的TSC通信请求可以包括PDU会话修改请求或PDU会话建立请求。在本申请实施例中将不做具体限定。
302、第一网络设备确定第一业务流的QoS需求中的时延需求和第二业务流的QoS需求中的时延需求。
本实施例中，由于5G是依据TSC会话的QoS需求来设置QoS流的，其中TSC会话的QoS需求的一个重要的特性是时延需求，对于TSC通信而言，第一UE与第二UE之间的TSC通信的时延通常要求非常精确。因此，第一网络设备可以根据第一TSC会话需求参数确定第一业务流的QoS需求中的时延需求和确定第二业务流的QoS需求中的时延需求。其中，该第一业务流的QoS需求中的时延需求是用于针对为第一UE建立第一QoS流所需要的时延需求，第二业务流的QoS需求中的时延需求是用于针对为第二UE建立第二QoS流所需要的时延需求。
另外需要说明的是，第一业务流的QoS需求中的时延需求是第一业务流的QoS需求中的参数，第二业务流的QoS需求中的时延需求是第二业务流的QoS需求中的参数。
可选地，在一些实施例中，第一UE可以连接在相应的第一UPF，第二UE可以连接在相应的第二UPF，也就是当第一UE与第二UE连接在不相同的UPF网元时，对于确定第一业务流的QoS需求中的时延需求和第二业务流的QoS需求中的时延需求可以采用如下方式，即：
所述第一网络设备根据所述第一TSC会话需求参数中的时延、所述第一UE与DS-TT之间的时延、所述第一UE的NW-TT的传输时延、所述第二UE与DS-TT之间的时延以及所述第二UE的NW-TT的传输时延来确定第一业务流的QoS需求中的时延需求；同样地，可以根据所述第一TSC会话需求参数中的时延、所述第一UE与DS-TT之间的时延、所述第一UE的NW-TT的传输时延、所述第二UE与DS-TT之间的时延以及所述第二UE的NW-TT的传输时延来确定第二业务流的QoS需求中的时延需求。
参见如下公式所示，
Figure PCTCN2020121743-appb-000002
Figure PCTCN2020121743-appb-000003
其中，A为第一TSC会话需求参数中的时延，B为第一UE与DS-TT之间的时延，C为第一UE的NW-TT的传输时延，D为第二UE与DS-TT之间的时延，E为第二UE的NW-TT的传输时延。
也就是说上述的第一业务流的QoS需求中的时延需求和第二业务流的QoS需求中的时延需求可以相等。
需要说明的是，上述所描述的所述第一UE与DS-TT之间的时延是由与第一UE连接的DS-TT进行测量得到的，在得到该第一UE与DS-TT之间的时延之后，透明地通过第一UE、第一SMF、第一PCF上报给第一网络设备，而上述所描述的所述第一UE的NW-TT的传输时延是指第一UE的NW-TT与外部TSN DN(数据网络)的通信之间的时延，由与第一UE连接的NW-TT进行测量得到的，在得到该值之后，透明地通过第一UPF、第一SMF、第一PCF上报给第一网络设备。同理，由于第一UE与第二UE所连接的实体网元均不相同，那么上述所描述的所述第二UE与DS-TT之间的时延是由与第二UE连接的DS-TT进行测量得到的，在得到该第二UE与DS-TT之间的时延之后，透明地通过第二UE、第二SMF、第二PCF上报给第一网络设备，而上述所描述的所述第二UE的NW-TT的传输时延是由与第二UE连接的NE-TT进行测量得到的，在得到该第二UE的NW-TT与外部TSN DN之间的时延之后，透明地通过第二UPF、第二SMF、第二PCF上报给第一网络设备。
可选地，在另一些实施例中，第一UE可以与第二UE连接在相同的UPF网元中，此时当第一UE与第二UE连接在相同的UPF网元时，对于确定第一业务流的QoS需求中的时延需求和第二业务流的QoS需求中的时延需求可以采用如下方式，即：
所述第一网络设备根据第一TSC会话需求参数中的时延、所述第一UE与DS-TT之间的时延、所述第二UE与DS-TT之间的时延来确定第一业务流的QoS需求中的时延需求；同理，第一网络设备根据所述第一TSC会话需求参数中的时延、所述第一UE与DS-TT之间的时延、所述第二UE与DS-TT之间的时延来确定第二业务流的QoS需求中的时延需求。
参见如下公式所示，
Figure PCTCN2020121743-appb-000004
Figure PCTCN2020121743-appb-000005
需要说明的是，第一网络设备可以通过NW-TT与UPF上报的Bridge ID信息来判断出第一UE与第二UE是否连接在相同的UFP网元上，若Bridge ID与UFP网元的ID相同，那么第一网络设备就可以判断出第一UE与第二UE连接在相同的UPF上。
此时，因为NW-TT是UPF中的一部分功能，第一UE与第二UE的通信在UPF与NW-TT内部进行，无需UPF和NW-TT与外部TSN DN进行数据交换与通信，因此，第一网络设备在分别使用(公式一)和(公式二)计算第一业务流的QoS需求中的时延需求与第二业务流的QoS需求中的时延需求时，需要设置所述第一UE的NW-TT传输时延和所述第二UE的NW-TT的传输时延均为零或不使用第一UE的NW-TT的传输时延与第二UE的NW-TT的传输时延，从而分别得到上述的(公式三)与(公式四)。
进一步说明的是，第一网络设备在计算第一业务流的QoS需求中的时延需求与第二业务流的QoS需求中的时延需求时，是基于TSN的时钟域相对于5G的时钟域的时间计算单元比rateRatio＝1，若TSN的时钟域与5G的时钟域的时间计算单元比rateRatio不等于1，则需要将上面(公式一)至(公式四)中的TSN域的时间参数全部映射到5G时钟域的时间参数，例如，TSN域的“业务流的QoS需求对应的时延”除以rateRatio，得到5G时钟域“业务流的QoS需求对应的时延”，然后再作计算。
303、第一网络设备向所述第一UE对应的第一PCF发送所述第一业务流的QoS需求和第一信息，以及向第二UE对应的第二PCF发送第二业务流的QoS需求和第二信息。
本实施例中，由于TSC通信请求可以包括PDU会话创建请求或者PDU会话修改请求，那么需要在PDU会话创建请求或者PDU会话修改请求的过程中，第一网络设备将根据上述描述的第一TSC会话需求参数中的时延、所述第一UE与DS-TT之间的时延、所述第一UE的NW-TT的传输时延、所述第二UE与DS-TT之间的时延、所述第二UE的NW-TT传输时延通过前面的(公式一)和(公式三)计算得到的第一业务流的QoS需求中的时延需求，以及根据上述描述的第一TSC会话需求参数中的时延、所述第一UE与DS-TT之间的时延、所述第一UE的NW-TT传输时延、所述第二UE与DS-TT之间的时延、所述第二UE的NW-TT的传输时延通过前面的(公式二)和(公式四)计算得到的第二业务流的QoS需求中的时延需求之后，将第一业务流的QoS需求中的时延需求包含于上述所描述的第一业务流的QoS需求中，将第二业务流的QoS需求中的时延需求包含于上述所描述的第二业务流的的QoS需求中，并结合第一信息、第二信息，分别发送给第一PCF和第二PCF。
需要理解的是，上述所描述的第一PCF和第二PCF一般是不相同的网元。
304、第一PCF将第一业务流的QoS需求映射为第一业务流的QoS策略。
本实施例中，由于TSN通信系统是依据业务流的QoS需求来设置QoS流的，而第一PCF是负责第一UE的策略控制，因此在接收到第一网络设备的发送的第一业务流的QoS需求后，便可以将该第一业务流的QoS需求映射成第一业务流的QoS策略。这样，便可以将该第一业务流的QoS策略发送给相应的第一SMF，从而使得第一SMF根据该第一业务流的QoS策略将第一业务流映射到QoS流中，从而建立起传输所述第一UE的业务数据的第一QoS流。
应当理解的是，第一PCF在接收了第一网络设备发送的第一业务流的QoS需求后，便相应的得到该第一业务流的QoS需求中的时延需求，此时第一PCF可以对该第一业务流的QoS需求中的时延需求对应的值进行修改，从而得到第一业务流的QoS策略中的时延值。这样，第一PCF在映射得到第一业务流的QoS策略后，也可以将该第一业务流的QoS策略中的时延值包含在该第一业务流的QoS策略内。
需要说明的是，该第一PCF也可以不修改该第一业务流的QoS需求中的时延需求对应的值，那么这样得到的第一业务流的QoS策略中的时延值则与该第一业务流的QoS需求中的时延需求对应的值相等。
305、第一PCF向第一SMF发送第一业务流的QoS策略和第一信息。
本实施例中，由于5G通信系统是依据业务流的QoS需求来建立QoS流的，而业务流的QoS需求最主要的一个特性则是业务流的时延需求。而该第一业务流的QoS策略包含了第一业务流的QoS策略中的时延值，因此第一PCF可以将该第一业务流的QoS策略发送给第一SMF，使得第一SMF能够获取到该第一业务流的QoS策略、以及该第一业务流的QoS策略中的时延值。
需要说明的是，该第一业务流的QoS策略中的时延值，是为了使得第一SMF在建立起传输第一UE的业务数据的第一QoS流的过程中，将该所需求建立起的第一QoS流的PDB值设置为小于或等于该第一业务流的QoS策略中的时延值，这样，使得第一QoS流传输此第一业务流时，其传输时延小于或等于该第一PCF所提供的第一业务流的QoS策略中的时延值。
306、当第一SMF设置第一QoS流的PDB值小于或等于所述第一业务流QoS策略的时延值时，第一SMF根据所述第一业务流的QoS策略建立传输所述第一UE的业务数据的第一QoS流。
本实施例中，由于第一业务流的QoS策略包括了建立QoS流所应用到的QoS参数，如：第一业务流的QoS策略中的时延值。所以第一SMF可以在设置第一QoS流的PDB值小于或等于第一业务流的QoS策略中的时延值时，且根据该第一业务流的QoS策略来建立起传输该第一UE的业务数据的第一QoS流。另外，第一SMF根据第一PCF所提供的第一UE的第一信息，当为第一UE建立起一个第一QoS流时，可以为这个第一QoS流分配对应的DS-TT上的一个第一Port以及NW-TT上的一个第二Port，从而组成一个Port对。
307、第一SMF将所述第一业务流的QoS策略、所述TSCAI信息映射到N2会话消息中，将所述第一业务流的QoS策略映射到所述N1会话消息中。
本实施例中，第一SMF可以将该第一业务流的QoS策略所包含的QoS参数映射到QoS配置(QoS Profile)，然后结合上述收到的第一UE的第一信息中包含的TSCAI信息载入到N2会话消息，提供给第一UE所对应的5G基站gNB；另外，还需要将第一业务流的QoS策略所包含的QoS参数映射到QoS规则(QoS Rule)后及收到的第一UE的第一信息中包含的DS-TT端口配置信息，载入N1会话消息中，提供给第一UE。应当理解的是，由于上述所描述的TSCAI信息是基于TSN时钟域的参数值，所以第一SMF需要将其通过映射等形式转换到5G系统的时钟域值。
308、第一SMF将N2会话消息和N1会话消息发送给第一AMF。
309、第一AMF向第一UE发送N1会话消息。
本实施例中，在第一UE在接收第一AMF发送的QoS规则以及第一信息中的DS-TT端口管理信息后，第一UE便可以在配置业务流数据后根据QoS规则以及TSC端口管理信息将该业务流数据发送至第二UE了或者接收第二UE发送的业务流数据，从而建立起了第一UE与第二UE之间的TSC通信。
310、第二PCF将第二业务流QoS需求映射为第二业务流的QoS策略。
本实施例中，由于5G通信系统是依据业务流的QoS需求来建立QoS流的，第二PCF是负责第二UE的策略控制，因此在接收到第二网络设备发送的第二业务流的QoS需求后，便可以将该第二业务流的QoS需求映射成第二业务流的QoS策略。这样，便可以将该第二业务流的QoS策略发送给相应的第二SMF，使得第二SMF根据该第二业务流的QoS策略将第二业务流映射到QoS流中，从而建立起传输所述第二UE的业务数据的第二QoS流。
应当理解的是，第二PCF在接收了第二网络设备发送的第二业务流的QoS需求后，便相应的得到该第二业务流的QoS需求中的时延需求，此时第二PCF可以对该第二业务流的QoS需求中的时延需求对应的值进行修改，从而得到第二业务流的QoS策略中的时延值。这样，第二PCF在映射得到第二业务流的QoS策略后，也可以将该第二业务流的QoS策略中的时延值包含在该第二业务流的QoS策略内。
需要说明的是，该第二PCF也可以不修改该第二业务流的QoS需求中的时延需求对应的值，那么这样得到的第二业务流的QoS策略中的时延值则与该第二业务流的QoS需求中的时延需求对应的值相等。
311、第二PCF向第二SMF发送第二业务流的QoS策略和第二信息。
本实施例中，由于5G通信系统是依据业务流的QoS需求来建立QoS流的，而业务流的QoS需求最主要的一个特性则是业务流的时延需求。而该第二业务流的QoS策略中包含了该第二业务流的QoS策略中的时延值，因此第二PCF可以将该第二业务流的QoS策略发送给相应的第二SMF，使得第二SMF能够获取到该第二业务流的QoS策略、以及该第二业务流的QoS策略中的时延值。
需要说明的是，该第二业务流的QoS策略中的时延值，是为了使得第二SMF在建立起传输第二UE的业务数据的第二QoS流的过程中，将该所需求建立起的第二QoS流的PDB值设置为小于或等于该第二业务流的QoS策略中的时延值，这样，使得第二QoS流传输此第二业务流时，其传输时延小于或等于该第二PCF所提供的第二业务流的QoS策略中的时延值。
312、当第二SMF设置第二QoS流的PDB值小于或等于所述第二业务流的QoS策略中的时延值时，第二SMF根据所述第二业务流的QoS策略建立传输所述第二UE的业务数据的第二QoS流。
本实施例中，由于第二业务流的QoS策略包括了建立QoS流所应用到的QoS参数，如：第二业务流的QoS策略中的时延值。所以第二SMF可以在设置第二QoS流的PDB值 小于或等于所述第二业务流的QoS策略中的时延值时，且根据该第二业务流的QoS策略来建立起传输该第二UE的业务数据的第二QoS流。另外，第二SMF根据第二PCF所提供的第二UE的第二信息，当为第二UE建立起一个第二QoS流时，可以为这个第二QoS流分配对应的DS-TT上的一个第一Port以及NW-TT上的一个第二Port，从而组成一个Port对。
313、第二SMF将所述第二业务流的QoS策略、所述TSCAI信息映射到N2会话消息中，将所述第二业务流的QoS策略映射到所述N1会话消息中。
本实施例中，具体地第二SMF可以将该第二业务流的QoS策略所包含的QoS参数映射到QoS配置(QoS Profile)，然后结合上述收到的第二UE的第二信息中包含的TSCAI信息载入到N2会话消息，提供给第二UE所对应的5G基站gNB；另外，还需要将第二业务流的QoS策略所包含的QoS参数映射到QoS规则(QoS Rule)后及收到的第二UE的第二信息中包含的DS-TT端口配置信息，载入N1会话消息中，提供给第二UE。应当理解的是，由于上述所描述的TSCAI信息是基于TSN时钟域的参数值，所以第二SMF需要将其通过映射等形式转换到5G系统的时钟域值。
314、第二SMF将N2会话消息和N1会话消息发送给第二AMF。
315、第二AMF向第二UE发送N1会话消息。
本实施例中，在第二UE在接收第二AMF发送的QoS规则以及第二信息中的DS-TT端口管理信息后，第二UE便可以在配置业务流数据后根据QoS规则以及TSC端口管理信息将该业务流数据发送至第一UE了或者接收第一UE发送的业务流数据，从而建立起了第一UE与第二UE之间的TSC通信。
应该理解的是，上述步骤304-309与步骤310-315的执行顺序不做限定，在实际应用中，也可以先执行步骤310-315后执行步骤304-309，又或者步骤304-309与步骤310-315还可以同步执行，具体本申请实施例中将不做具体限定。
本申请实施例中，通过第一UE发起TSC通信请求，使得第一网络设备在确定第一业务流的QoS需求、第二业务流的QoS需求后分别提供给第一UE和第二UE所在的5G网络，从而分别触发建立起用于传输第一UE的业务数据的第一QoS流，及触发建立起用于传输第二UE的业务数据的第二QoS流，实现了由UE发起TSC通信请求来建立第一UE与第二UE之间的TSC传输通道。
