  • the current time is 1 o'clock under the 5G clock, and 2 o'clock under the TSN clock. Therefore, the corresponding time positions of the same time information (such as the data arrival time) under different clocks may be different.

  • the time length corresponding to the same time information (such as time delay) under different clocks may also be different.
  • Time-sensitive data streams are highly time-sensitive, and time differences may cause errors in task execution. For example, a production machine in a factory needs to operate at 0:00:00. If there is a one-hour time difference between the reference clock of the command and the clock of the machine, it will miss work. If there is a 0.1 second time accuracy deviation between the reference clock of the command and the clock of the machine, it will also cause subsequent work connection errors.

  • Some time-related information is configured to the 5G bridge by the controller (such as CNC) of the time-sensitive network (such as TSN) or time-sensitive applications. It needs to be adjusted from the time-related information based on the TSN clock to the time-related information based on the 5G clock.

This is undoubtedly inefficient.
  • One solution is to provide the AF with the bridge delay based on two clocks or the time information used to generate the bridge delay based on the two clocks.
  • AF can send network time-related information based on different clocks according to the needs of different nodes.
  • AF needs to report bridge delay to time-sensitive network controllers (such as CNC), and communication network elements such as PCF need to map TSN data streams to corresponding communication network QoS (such as 5G QoS) for TSN QoS requirements.
  • the delay in the QoS of the communication network is the PDB, not the overall bridge delay. If what AF provides to PCF is the bridge delay corresponding to the data flow. The PCF also needs to subtract the stay time of the terminal and the DS-TT from the bridge delay to map the communication network QoS. This will undoubtedly put forward new requirements for the functions of PCF.
  • a solution AF obtains the bridge delay, and the AF sends the bridge delay to the PCF.

参考图1，为本发明实施例提供的一种可应用无线通信系统的架构示意图。在本发明实施例中，时间敏感数据流发送端可以称为talker，时间敏感数据流的接收端可以称为listener。talker和listener之间可以通过的一个或多个网桥进行数据的转发。终端站节点(End Station)可以是talker或listener。网桥(Bridge)负责talker和listener之间的数据传送。
终端(User Equipment，UE)、时间敏感适配器和通信网络构成一个网桥(后续以5G网桥为例说明)。对下行数据，设备侧时间敏感网络适配器(Device-side TSN translator，DS-TT)的端口可以是数据的出端口，网络侧时间敏感网络适配器(Network-side TSN translator，NW-TT)的端口是数据的入端口。对上行数据，NW-TT的端口可以是数据的入端口，DS-TT的端口是数据的出端口。终端可以和DS-TT合设。用户面功能(User Plane Function，UPF)可以和NW-TT合设。

需要说明的是，图1仅是一个举例示意图，本发明实施例中，并不限定第5G网桥的结构，以及5G网桥中端口之间的连接关系。
为了支持终端、时间敏感适配器和无线通信网络构成的网桥的实现，还需要解决以下问题：
问题1：5G网桥中存在5G时钟，TSN网络中存在TSN时钟。5G时钟与TSN时钟之间存在时间差(比如时差)和时间频率的不同。1)对于时间差，比如当前时间在5G时钟下是1点，而在TSN时钟下是2点。因此，同一时间信息(比如数据到达时间)在不同时钟下的对应的时间位置可能不同。2)不同时钟的时钟频率存在不同，就会造成时间精度的不同，比如：3.14秒与3.14159秒的区别。同一时间信息(比如时延)在不同时钟下对应的时间长度也可能不同。时间敏感数据流对时间敏感程度要求很高，时间差异可能导致任务执行出错。比如工厂中的生产机器需要在0点0分0秒进行操作，如果下指令的参考时钟与机器的时钟有一个小时的时差就会误工。如果下指令的参考时钟与机器的时钟间存在0.1秒的时间精度偏差，也会导致后续的工作衔接错误。因此，对时间相关信息，如数据到达时间，时延等，需要根据5G时钟与TSN时钟间差异进行调整。
有些时间相关信息是时间敏感网络(如TSN)的控制器(如CNC)或时间敏感应用配置给5G网桥的，需要从基于TSN时钟的时间相关信息调整为基于5G时钟的时间相关信息，而有些时间相关信息是5G网桥发送给时间敏感网络，需要从基于5G时钟的时间相关信息调整为基于TSN时钟的时钟相关信息。在5G网桥中，TT(TSC Translator时间敏感网络适配器)同时与5G时钟和TSN时钟同步，可以监测到两个时钟的差异。由于NW-TT与UPF合设，UPF可以向SMF提供两个时钟的差异，SMF可以将基于5G时钟的时间相关信息调整为基于TSN时钟的时间相关信息，也可以将基于TSN时钟的时间相关信息调整为基于5G时钟的时间相关信息。
AF作为5G网桥的控制面出口，一方面要将网桥时延上报给CNC，此时，网桥时延是基于TSN时钟的网桥时延。另一方面，当时间敏感数据流的控制信息(如PSFP((per-stream filtering and policing)信息、Traffic forwarding information)到达时，需要将时间敏感数据流对应的网桥时延对应映射所述数据流的QoS信息(包含数据包时延)，以保障时间敏感数据的传送。此时的网桥时延是基于5G时钟的网桥时延。AF是根据UE与DS-TT停留时间(也 称为UE与DS-TT的端口间时延)和数据包时延预算(Packet Delay Budget，PDB)生成的网桥时延。如果只提供基于一种时钟相关的网桥时延或用于生成网桥时延的时间信息(如终端与DS-TT的停留时间、PDB)，则需要向AF频繁同步两个时钟的差异信息。这无疑是效率欠佳的。
一种解决的方法是向AF提供基于两个时钟的网桥时延或基于两个时钟的用于生成网桥时延的时间信息。AF可以根据不同节点的需求发送基于不同时钟的网时间相关信息。
问题2：AF需要向时间敏感网络的控制器(如CNC)上报网桥时延，而通信网络网元如PCF，需要为TSN数据流映射TSN QoS需求对应的通信网络QoS(如5G QoS)。通信网络的QoS中的时延是PDB，而不是整体的网桥时延。如果AF向PCF提供的是数据流对应的网桥时延。PCF还需要将所述网桥时延减去终端与DS-TT的停留时间才能映射通信网络QoS。这无疑会对PCF的功能提出新的要求。
对问题2，可以存在多种解决方法，包括但不限于如下：
(1)一种解决的方法：AF获取网桥时延，AF将网桥时延发送给PCF。PCF将其减去终端与DS-TT的停留时间计算获取时延(如PDB相关时延)后，再根据所述计算的时延映射通信网络QoS。
(2)另一种解决的方法：AF获取网桥时延，AF将网桥时延减去终端与DS-TT的停留时间计算获取时延信息后，再将所述时延信息发送给PCF，PCF根据所述时延可以直接映射通信网络QoS。
结合问题1，解决方法(1)(2)中AF获取的网桥时延可以是分别对应5G时钟和TSN时钟的两种网桥时延，或者是对应TSN时钟的网桥时延，或者是对应5G时钟的网桥时延。AF可以接收获取网桥时延或者接收用于计算网桥时延的时间相关信息计算获得网桥时延。AF发送给PCF的网桥时延可以是基于5G时钟的网桥时延。
(3)另一种解决的方法：AF获取的是网桥时延和PDB，AF可以保存所述PDB。AF可以将数据流(如TSC数据流)映射的PDB作为数据流的时延要求发送给PCF，PCF根据所述时延映射通信网络QoS。
结合问题1，解决方法(3)中所述网桥时延可以是基于TSN时钟。所述 PDB可以是基于5G时钟。
(4)另一种解决的方法：AF获取终端与DS-TT的停留时间和PDB，AF可以保存所述PDB。AF可以将数据流(如TSC数据流)映射的PDB作为数据流的时延要求发送给PCF，PCF根据所述时延映射通信网络QoS。
结合问题1，解决方法(4)AF获取的PDB可以是分别对应5G时钟和TSN时钟的两种PDB，或者是对应TSN时钟的PDB，或者是对应5G时钟的PDB。AF发送给PCF的PDB可以是基于5G时钟的PDB。
问题3.5G网桥时延只有一个取值，缺乏弹性。5G网桥时延区分最大时延和最小时延时，对应地，用于生成网桥时延的PDB和终端与DS-TT的停留时间也可以区分最大值，最小值。最小值还可以进一步区分与traffic class相关的最小值，与traffic class不相关的最小值。最大值还可以进一步区分与traffic class相关的最大值，与traffic class不相关的最大值。
本发明实施例中，可选的，获取可以理解为生成、从配置获得、接收、通过请求后接收、通过自学习获取、根据未收到的信息推导获取或者是根据接收的信息处理后获得，具体可根据实际需要确定，本发明实施例对此不作限定。比如当未收到设备发送的某个能力指示信息时可推导出该设备不支持该能力。

本发明一种可选实施例中，端口对的时延可以是区分业务类(per traffic class)的网桥时延。每个端口可以支持一个或多个业务类。每个业务类的传输性能不同，所以不难理解，出端口的每种业务类都具有的端口对的时延。每个业务类的端口对的时延可以不同。
也就是说，端口时延也可以是指某一种业务类的网桥时延，当然，不同的业务类的网桥时延可以相同或者不同。
