具体实施方式
下面将结合本发明实施例中的附图,对本发明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发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。
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。
在本发明实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“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。
下面结合附图介绍本发明的实施例。本发明实施例提供的信息传输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5G系统,或者演进型长期演进(Evolved Long Term Evolution,eLTE)系统,或者后续演进通信系统。
在本发明实施例中,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称为周期确定性数据流。一种时间敏感的网络技术,比如IEEE时间敏感网络(Time Sensing Network,TSN)。周期确定性通信是以传送间隔为周期进行数据传送。
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)、时间敏感适配器和无线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。
如图1所示,一个终端可以连接一个或多个DS-TT,一个DS-TT上可以有一个或多个端口。一个5G网桥可以有一个UPF,所述UPF的NW-TT上可以启用一个或多个端口。终端可以作为DS-TT的端口的代理,与UPF建立协议数据单元(Protocol Data Unit,PDU)会话。通过所述PDU会话,DS-TT上的端口与UPF合设的NW-TT的端口建立关联。DS-TT的所述端口成为5G网桥的一个端口。
DS-TT的端口和NW-TT的端口都可以分别连接,TSN网桥(TSN Bridge)和/或终端站(End Station)。通过所述5G网桥,TT的端口连接的TSN网桥和/或终端站就可以进行通信。
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1:一个DS-TT端口可以与多个NW-TT端口分别组成端口对。比如DS-TT侧的端口为A1,A2多个端口,比如NW-TT上有B1,B2,B3多个端口。则端口对可以是[A1,B1],[A1,B2],[A1,B3],[A2,B1],[A2,B2],[A3,B3]。目前,由AF计算不同端口对的时延,端口对的时延为数据包从端口对的一个端口到另一个端口通过所需要的时间。不难理解,可以存在三种类型的端口对:两个DS-TT端口构成的端口对,一个DS-TT端口与一个NW-TT端口构成的端口对,两个NW-TT端口构成的端口对。不难理解,三种类型的端口对的时延计算是不同的。因此,为了构成端口对和确定端口对的时延,则需要端口的TT类型。但目前,AF不区分DS-TT端口和NW-TT端口。
问题2:一个DS-TT端口与一个NW-TT构成的端口对间的时延(delay) 计算时,是终端与DS-TT之间的处理时间(UE to DS-TT residence time)加上数据包时延预算(Packet Delay Budget,PDB)。
终端与DS-TT之间的处理时间是数据包在DS-TT端口与终端间通过的时延;其与DS-TT的端口相关的。数据包时延预算(Packet Delay Budget,PDB)是数据包在终端与NW-TT端口间通过的时间,应该与NW-TT的端口相关。而目前,PDB是不区分NW-TT的端口的。一种实施方式中,每个NW-TT的端口配置相同的PDB,即数据包从数据包在终端与任一NW-TT端口间通过的时间都相同。另一种实施方式中,每个NW-TT的端口配置相同的PDB不同。PDB区分NW-TT端口。
问题3:从一个NW-TT端口接收的不同的数据包可能是发往不同的DS-TT端口的。不同的DS-TT数据包对应不同的PDU会话,不同的PDU会话的SMF可以不同。NW-TT目前还缺乏信息来选择一个DS-TT端口。UPF也缺乏信息选择一个DS-TT端口对应的PDU会话。
问题4:目前,NW-TT端口与DS-TT的PDU会话没有关联关系,也不应该有关联关系。因为从一个NW-TT端口接收的不同的数据包可能是发往不同的DS-TT端口;从一个DS-TT端口接收的不同的数据包也可能是发往不同的NW-TT端口。但目前NW-TT端口的端口相关信息时,是通过DS-TT端口相关的PDU会话的相关信令来发送的。比如UPF将NW-TT端口的端口相关信息发送给DS-TT端口相关的PDU会话的SMF,所述SMF将NW-TT端口的端口相关信息发送给DS-TT端口相关的PDU会话策略的PCF。再由所述PCF将NW-TT端口的端口相关信息发送给AF。
当DS-TT还没有接入时,NW-TT的端口相关信息生成或更新时,无法发送给AF。因此,等候DS-TT的PDU会话建立后再进行转发。
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。
可选的,发送可以包含广播,系统消息中广播,响应请求后返回。
可选的,预配置的可以称为默认的。
在本发明一种可选实施例中,所述端口管理容器也可以称为端口管理信息容器。所述端口管理容器为承载端口控制信息(也称为端口管理信息)的容器。
在本发明一种可选实施例中,所述端口相关信息包括:端口管理容器。在本发明一种可选实施例中,所述端口相关信息可以理解为网桥管理任一项或多项关于端口的信息(如802.1Q中网桥管理中端口相关配置信息)。
在本发明一种实施例中,所述端口可以为以下之一以太网端口、IP端口。
在本发明一种可选实施例中,数据通道可以包括但不限于以下之一:PDU会话,PDN连接,QoS流,承载,互联网安全协议(Internet Protocol Security,IPsec)通道,其中,承载可以是演进的无线接入承载(Evolved Radio Access Bearer,E-RAB)、无线接入承载(Evolved Radio Access Bearer,RAB)、数据无线承载(Data Radio Bearer,DRB)、信令无线承载(signalling radio bearers,SRB)等。
本发明一种可选实施例中,端口对是由两个端口组成,例如:由同一DS-TT的两个端口组成,或者由不同的DS-TT的两个端口组成,或者由同一NW-TT的两个端口组成,或者由不同的NW-TT的两个端口组成。
本发明一种可选实施例中,端口对的时延(也可以称为端口对的网桥时延)可以是指,数据包从一个端口通过另一个端口的时间。所述两个端口可以是同一网桥(如5G网桥)的两个端口。不难理解,网桥时延可以是数据包通过网桥的时间开销。
例如:第一端口对由第一端口和第二端口组成,而端口对的时延可以是指,数据包从第一端口通过第二端口所用的时间。
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。
本发明一种可选实施例中,TT端口,TT的端口,TT上的端口,TT侧的端口,TT侧端口代表同一个意思,可以混用。
本发明一种可选实施例中,DS-TT端口,DS-TT的端口都代表位于DS-TT上的端口,可以混用;本发明一种可选实施例中,NW-TT端口,NW-TT的端口都代表位于NW-TT上的端口,可以混用。
本发明一种可选实施例中,DS-TT端口也可以等效为设备侧端口;而NW-TT端口也可以等效为网络侧端口。端口的TT类型为DS-TT时可以等效为端口为设备侧端口;端口的TT类型为NW-TT时可以等效为端口为网络侧端口。
本发明一种可选实施例中,第一端口所在的TT的相关信息可以简称为第一端口的TT的相关信息或第一端口的TT相关信息。
本发明一种可选实施例中,端口对应的数据通道一般关联了一个DS-TT的端口。
在本发明一种可选实施例中,所述无线通信网络可以简称为网络。
本发明一种实施例中,无线通信网络可以是以下至少一项:公网,非公网。
在本发明一种实施例中,非公网是非公众网络的简称。非公众网络可以称为以下之一:非公众通信网络。非公网可以包括以下至少一种部署方式:独立组网的非公网(如SNPN),非独立组网的非公网(如封闭的访问组(Closed Access Group,CAG))。在本发明一种实施例中,非公众网络可以包含或称为私有网络。私有网络可以称为以下之一:私有通信网络、私网、本地区域网络(LAN)、私有虚拟网络(PVN)、隔离的通信网络、专用的通信网络或其他命名。需要说明的是,在本发明实施例中对于命名方式不做具体限定。
