背景技术
许多垂直行业都有时间敏感通信的需求。在工业互联网中，存在时间敏感数据，比如机器人指令，需要在指定时间内按序执行。但网络传送资源是共享的，数据传送存在时延和抖动，不能支持时间敏感的数据。所以，一种时间敏感的网络被提出，以支持时间敏感数据的传送。
时间敏感数据流发送端称为talker，时间敏感数据流的接收端称为listener。talker和listener之间通过的一个或多个网桥进行数据的转发。Talker、listener或网桥的传输媒介都有可能是无线连接。所以，无线通信系统可以构成网桥。如何支持将无线通信系统构成网桥，是亟待解决的技术问题。

具体实施方式
本公开实施例提供的支持端口控制的方法及通信设备可以应用于无线通信系统中。该无线通信系统可以为第五代移动通信(Fifth-generation，5G) 系统，或者演进的分组系统(Evolved Packet System，EPS)，或者后续演进通信系统。本公开实施例无线通信网络可以为第五代移动通信网络(Fifth-generation system，5GS)或LTE网络。下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参考图1，为本公开的一些实施例提供的一种无线通信系统的架构示意图。
时间敏感数据流发送端称为talker，时间敏感数据流的接收端称为listener。talker和listener之间通过的一个或多个网桥进行数据的转发。结束站节点(End Station)可以是talker或listener。网桥(Bridge)负责talker和listener之间的数据传送。
用户设备(User Equipment，UE)、时间敏感适配器和无线通信网络构成一个网桥(后续称为第一网桥)。对下行数据，第一适配器是网桥(Bridge)出口，第二适配器是网桥入口。对上行数据，第一适配器网桥入口，第二适配器是网桥出口。
第一适配器是设备侧的时间敏感网络的适配器(如DS-TT)。第一适配器的端口可以用于连接其他网桥或End Station。第二适配器是网络侧的时间敏感网络的适配器(如NW-TT)。第二适配器的端口可以用于连接其他网桥或End Station。
第一适配器和/或第二适配器可以是时间敏感网络的适配器。时间敏感网络的适配器也可以称为时间敏感网络的翻译器(TSN(Time Sensing Network)TRANSLATOR)。
UE可以和第一适配器合设。用户面功能(User Plane Function，UPF)可以和第二适配器合设。
UE可以作为第一适配器的代理，与UPF建立协议数据单元(Protocol Data Unit，PDU)会话。通过所述PDU会话，第一适配器上的端口与UPF上的第二适配器上的端口产生关联。第一适配器的所述端口成为第一网桥的一个端 口。
参见图2，当时间敏感网络的设备缺乏有线连接时，无线通信系统构成的网桥可以通过设备侧时间敏感网络翻译(Device-side TSN translator，DS-TT)和网络侧时间敏感网络翻译(Network-side TSN translator，NW-TT)上的端口连接同一个时间敏感网络的设备，特别是DS-TT和NW-TT两侧的设备缺乏有线连接时。
为了支持网桥端口的配置，还需要解决以下需求：
1)为了将时间敏感数据流在有限时延内送达End Station，需要在数据发送之前确定时间敏感数据流经过的路径，即网桥和网桥的端口。对集中式架构来说，CNC(时间敏感网络的控制面节点)对网桥的端口进行数据流的路由配置(比如当网桥使用生成树协议时，配置Static Filtering Entry，当网桥支持冗余路径(redundant path)时，配置static tress)。路由配置比如配置端口可以通过的媒体接入控制(Media Access Control Address，MAC)地址和虚拟局域网标识(Virtual Local Area Network，VLAN)ID等。配置完成后，当携带所述MAC地址和VLAN ID的数据流就可以通过所述端口转发。
2)网桥有可能会接收到非时间敏感数据流。为了将时间敏感数据流在有限时延内送达End Station，在网桥调度时，时间敏感数据流处于较高的优先级。而非时间敏感数据流的优先级可以降低为较低的优先级(如优先级0)。此时，需要对端口配置优先级重生成表(Priority Regeneration Table or Priority Regeneration Override Table)，重新映射优先级。
3)在集中式架构中，可以对网桥的端口进行以下配置：传送选择算法相关信息，带宽可用性参数。
问题：针对1)，2)和3)的需求，当网桥是UE、时间敏感适配器和无线通信网络构成网桥时，在第一适配器通过UE接入无线通信网络成为网桥的组成部分之前，一方面无法提前对第一适配器的端口进行提前配置；另一方面也无法读取第一适配器的端口的相关配置信息。另外，有些网桥的配置信息是区分端口的，区分端口的不同业务类的，可以直接配置给端口。另一些网桥的配置信息是网桥整体的，如何对应到网桥中的个别端口也是亟待解决的问题。
可选的，获取可以理解为从配置获得、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，本公开的一些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。
