具体实施方式
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。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清 楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
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，提出一种时间敏感的网络，以支持时间敏感数据的传送。
时间敏感网络将时间划分为间隔(Interval)，可称为滑动窗口。在每个滑动窗口定义时间敏感数据流的流量标准(traffic specification)，提前预留传送资源。这样，当传送数据的滑动窗口到达时，即使没有时间敏感数据流，网络资源也不能被其他数据流占用。当时间敏感数据流到达时，占用专用资源进行传送。
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，无线通信网络可以是时间敏感网络中的传输媒介。如何在无线通信网络如何支持时间敏感通信服务质量，是目前亟待解决的技术问题。
在本公开实施例中，时间敏感(Time Sensing)也可以称为周期确定性(Periodic deterministic)。时间敏感通信也可以称为周期确定性通信(Periodic deterministic communication)。时间敏感数据流也可以也可以称为周期确定性数据流。一种时间敏感的网络技术比如IEEE TSN(Time Sensing Network)。周期确定性通信是以传送间隔为周期进行数据传送。
本公开实施例中，时间敏感数据流的传送配置信息可以包括用户和/或网络配置信息。用户和/或网络配置信息(User/Network Configuration Information)用于配置时间敏感数据流的发送。用户和/或网络配置信息可以为IEEE 802.1Q 系列中用户和/或网络配置信息。用户和/或网络配置信息可以包括以下至少一项：listener组(group)，talker组(group)，传送规范(traffic specification)。
参考图1，为本公开实施例提供的一种无线通信系统的架构示意图。
图中示出了下一代RAN(Next-Generation RAN，NG-RAN)，用户面功能(User Plane Function，UPF)，会话管理功能(Session Management Function，SMF)，策略控制功能(Policy Control Function，PCF)，时间敏感网络(Time Sensitive Networking，TSN)，应用功能(Application Function，AF)为，集中式网络配置功能(Centralized Network configuration，CNC)。
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之间通过一个或多个网桥进行数据的转发。End Station可以是talker或listener。Bridge负责talker和listener之间的数据传送。
终端和无线通信网络构成一个网桥。对下行数据，终端是网桥(Bridge)出口，用户面功能(User Plane Function，UPF)是网桥入口。对上行数据，终端是网桥入口，UPF是网桥出口。
需要说明的是，终端可以和End Station合设，或者终端也可以与网桥合设。终端可以连接网桥或终端也可以连接End Station。
对于集中式的架构，无线通信网络可以通过CNC和AF获得用户和/或网络配置信息。对于分布式的架构，无线通信网络可以从网桥入口接收上一跳的用户和/或网络配置信息，再生成本网桥的用户和/或网络配置信息。
在本公开一种实施例中，终端与无线通信网络构成的网桥可以简称为终端与网络构成的网桥。
在本公开一种实施例中，传送间隔可以称为传送周期。
参考图2，为一种网桥时延(Bridge delay)构成示意图。
如图2所示，包括终端21、无线接入网(Radio Access Network，RAN)网元22和网关UPF23，其中，UPF23可是一个或多个UPF。RAN网元22与锚点UPF之间可以存在零个或多个UPF，即RAN网元22与锚点UPF之间可以没有其他的UPF。
参考图3，为一种时间敏感数据流在网桥中传输示意图。
为了支持时间敏感通信服务质量，还可以进一步解决如下问题：
问题1：为了支持时间敏感数据现有QoS中的保证比特速率(Guaranteed Bit Rate，GBR)速率和最大突发数据量是全时长的。然而，时间敏感数据传送是分段的，因此现有的GBR不适用于时间敏感数据传送。当一个或多个时间敏感数据流映射一个QoS流时，如何设置数据发送区间的GBR和最大突发数据量还不清楚。
另外由于时间敏感数据的时延要求是纳秒级别的，目前无线通信网络的时延是毫秒级别或0.5毫秒为单位的，精度不能够满足要求。
现有的数据包延迟预算(Packet Delay Budget，PDB)是终端到UPF之间最大数据包延迟预算。但RAN网元需要的是终端与RAN网元之间的时延预算。
问题2：RAN网元中，资源调度是根据数据无线承载(Data Radio Bearer，DRB)为粒度调度资源的。为了支持时间敏感数据通信，需要提前进行资源预留。对具有不同traffic specification元素(比如IEEE 802.1Q系列中的traffic specificiation)的时间敏感数据流时间敏感数据流，如果所述多个时间敏感数据流映射为一个QoS流中，将无法满足traffic specification的要求。Listener可能连接不同的终端，当数据到达锚点UPF时，则需要建立多个QoS流，分别连接到多个终端。对每个QoS流，需要映射独立的DRB，才能真正地保障资源预留。
问题3：时间敏感数据流的服务质量要求为用户和/或网络的配置信息(User/Network Configuration Information)中的业务规范traffic specification(比如IEEE 802.1Q系列中的traffic specificiation)。是否能够满足要求，需要网桥分配资源和返回成功或失败响应。终端与无线通信网络构成的网桥是否能够满足时间敏感数据流的服务质量要求基于一条终端到锚点网关(如UPF)之间的数据通道能否建立。数据数据通道用于承载所述敏感数据流。所述数据通道能否建立取决两方面a)时间敏感数据流的服务质量映射的无线通信网络的QoS要求是否能够满足，b)作为网桥出口的通信设备是否能够满足时间敏感数据流的服务质量要求。如何支持在QoS流建立的过程中，传送用户和/或网络的配置信息还需要解决。
需要说明的是，本公开实施例中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。
需要说明的是，本公开实施例中发送可以包含广播，系统消息中广播，响应请求后返回。
需要说明的是，时间敏感数据流映射的服务质量QoS流是指时间敏感数据流通过QoS流承载和传输。

以下对本公开实施例的支持时间敏感通信服务质量的方法进行说明。
请参考图4，本公开实施例还提供了一种支持时间敏感通信服务质量的方法，应用于第一通信设备。第一通信设备可以包括但不限于以下之一：PCF，SMF。该方法可以包括步骤401和步骤402。
步骤401：获取第一信息，第一信息可以包括以下至少一项：时间敏感数据流的传送配置信息，网桥的能力信息。
步骤402：根据第一信息，执行第一操作。

(2)依据接收流保留协议(Stream Reservation Protocol，SRP)消息中时间敏感数据流的传送配置信息生成时间敏感数据流的传送配置信息。
不难理解，集中式架构中，终端与无线通信网络构成的网桥的时间敏感数据流的传送配置信息是被集中配置的。在分布式架构中，终端与无线通信网络构成的网桥的时间敏感数据流的传送配置信息是通过接收SRP消息后自己生成的。
在本公开实施例中，可选地，网桥能力信息可以为终端和无线通信网络 (例如3GPP)构成的网桥的能力信息。进一步地，该网桥的能力信息可以包括：网桥时延。

(2.2)在本公开的一种实施例中，可选地，根据第一信息，确定第一GBR相关参数，可以包括：根据时间敏感数据流的传送配置信息中的传送间隔、最大数据帧大小、传送间隔内最大发帧数量、传送间隔内最早数据发送开始时间偏移、传送间隔内最晚数据发送开始时间偏移、抖动时间中的至少一项和数据发送区间的相关信息(参见2.1中的描述)，确定所述第一GBR相关参数。第一GBR相关参数也可以称为数据发送区间的GBR相关参数。
一种实施方式中，数据发送区间的GBR(GFBR或MFBR)设置为最大数据包大小×传送间隔内最大发包数量/第一时间区间。
进一步地，第一时间区间可以包括以下至少一项：
传送间隔；
传送间隔结束时间(或传送间隔内数据发送结束时间)减去传送间隔内数据发送开始时间；
传送间隔结束时间(或传送间隔内数据发送结束时间)减去传送间隔内最早数据发送开始时间；
传送间隔结束时间(或传送间隔内数据发送结束时间)减去传送间隔内最晚数据发送开始时间。
(2.3)在本公开的一种实施例中，可选地，根据第一信息，确定第一最大数据突发量，包括：根据时间敏感数据流的传送配置信息中的最大帧大小、 和/或传送间隔内最大发帧数量确定最大数据突发量。
一种实施方式中，最大数据突发量设置为最大帧大小×传送间隔内最大发帧数量。此时，所述第一最大数据突发量可以理解为数据发送区间的最大数据突发量。

一种实施方式中，第一时延为终端与RAN网元间时延。
示例性地：
下行：终端与RAN网元间时延＝数据最晚发送时间－RAN网元与锚点UPF间时延－终端的网桥时延－锚点UPF的网桥时延；
上行：终端与RAN网元间时延＝数据最晚发送时间－RAN网元与锚点UPF间时延－终端的网桥时延－锚点UPF的网桥时延。
(2.5)在本公开的一种实施例中，可选地，最大包大小为时间敏感数据流的最大帧大小。当QoS流映射了多个时间敏感数据流时，最大包大小为多个时间敏感数据流的最大帧大小。

(2.6)在本公开的一种实施例中，可选地，根据第一信息确定包过滤器信息，包括：将第一QoS流的包过滤器信息包含时间敏感数据流的数据帧规范(Data Frame Specification,如IEEE 802.1Q系列中的Data Frame Specification)；或者，将第一QoS流的包过滤器信息设置为时间敏感数据流的数据帧规范。
示例性的，当第一QoS流映射了第一时间敏感数据流，则第一QoS流的包过滤器信息中可以设置为第一时间敏感数据流的数据帧规范，用于将第一时间敏感数据流的数据映射到第一QoS流。后续，第一QoS流需要映射第二时间敏感数据流时，则第一QoS流的包过滤器信息中可以包含第一时间敏感数据 流的数据帧规范和第二时间敏感数据流的数据帧规范，用于将第一时间敏感数据流和第二时间敏感数据流的数据映射到第一QoS流。
(2.7)在本公开的一种实施例中，可选地，根据第一信息确定是否为时间敏感的指示信息，可以包括：将指示第一QoS流是否为时间敏感的指示信息设置为时间敏感。

可选地，所述第一目标端可以包括以下至少一项：RAN网元，终端，CN网元(如SMF，AMF，UPF)。
具体地，第一容器可以对传送第一容器的通信网元(如AMF，SMF，和/或RAN网元等)透明，对终端和/或锚点网关(如锚点UPF)可见。不难理解，作为网关出口的终端或锚点网关需要理解时间敏感数据流的传送配置信息，而传送时间敏感数据流的传送配置信息的通信网元可以不需要理解时间敏感数据流的传送配置信息。
一种实施方式，在建立或修改第一QoS流时，向第一目标端发送所述第一QoS相关信息、第一容器信息和/或时间敏感数据流的传送配置信息。
示例性地，通过在建立或修改第一QoS流的相关信令(如PDU会话修改的相关信令)中包含第一QoS相关信息、第一容器信息和/或时间敏感数据流的传送配置信息，实现向第一目标端发送所述第一QoS相关信息、第一容器信息和/或时间敏感数据流的传送配置信息。

具体地，第一容器可以对传送第一容器的通信网元(如AMF，SMF，和/或RAN网元等)透明，对终端和/或锚点网关(如锚点UPF)可见。不难理解，作为网关出口的终端或锚点网关需要理解时间敏感数据流的传送配置信息，而传送时间敏感数据流的传送配置信息的通信网元可以不需要理解时间敏感数据流的传送配置信息。
进一步地，所述第二目标端可以包括以下至少一项：RAN网元，终端，CN网元(如AMF，UPF)。
一种实施方式中，当所述第一QoS相关信息是授权的第一QoS相关信息时，第二通信设备为SMF，第二目标端可以为AMF；或者，第二通信设备为AMF，第二目标端可以为RAN网元和/或终端。
