Description

中继通信QoS保证的方法及相关装置 技术领域
本申请涉及通信技术领域，尤其涉及一种中继通信QoS保证的方法及相关装置。
背景技术
移动通信系统未来发展中，为了更好的满足用户需求，提升设备之间信息交互的效率，在设备与设备之间引入了PC5接口。当前PC5接口已可用于传输设备到设备发现(Device to Device Discovery，D2D Discovery)、设备到设备通信(Device to Device Communication，D2D Communication)和车辆到万物(Vehicle to Everything，V2X)。为了提升网络传输效率，降低用户设备UE功率消耗，在UE与UE之间引入PC5接口，图1A为PC5接口位置示意图，如图1A所示，用于D2D通信和V2X通信。
同时，为了扩展网络覆盖等原因，在用户设备(User Equipment，UE)与网络(network，NW)之间引入了中继relay。图1B为V2X中的relay示意图，如图1B所示，路边设备(Road Side Unit，RSU)作为relay，传递车辆与网络之间的上行链路(Up-Link，UL)数据，其中车辆与relay之间通过PC5接口通信，relay与network之间通过Uu口通信。UE1与UE2之间通过侧行链路(Sidelink Shared Channel，SL)连接。随着业务的多样化，PC5接口上可以同时传递多种业务，建立多个承载，比如设备到设备(Device to Device，D2D)通信中可能包含语音、视频等不同业务类型。

具体实施方式
下面将结合附图对本申请实施例中的技术方案进行描述。
如图1C所示，第二设备(简称w-UE或remote UE或远端UE)通过D2D通信的方式连接第一设备(简称relay UE或r-UE)，第一设备接入到网络设备，即w-UE可以连接到UE充当的中继节点，与r-UE之间以D2D的方式进行通信，r-UE负责将w-UE的数据包转发到网络或从网络转发给w-UE，第二设备例如可以是可穿戴/eMTC/NB-IoT设备，第一设备例如可以是手机等终端设备。
该示例通信系统100例如可以是：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access tounlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
本申请实施例中的第一设备110可以指用户设备、接入第一设备、用户单元、用户站、移动站、移动台、远方站、远程第一设备、移动设备、用户第一设备、第一设备、无线通信设备、用户代理或用户装置。第一设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、中继设备、车载设备、可穿戴设备，未来5G网络中的第一设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的第一设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备120可以是用于与第一设备通信的设备，该网络设备可以是LTE系统中的演进型基站(evoled NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继设备、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(baseband unit，BBU)，或，分布式单元(distributed unit，DU)等，本申请实施例并不限定。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network， RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
在本申请实施例中，第一设备110或网络设备120包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是第一设备，或者，是第一设备中能够调用程序并执行程序的功能模块。
目前，随着5G应用的不断发展，网络控制互动服务(Network Controlled Interactive Services，NCIS)业务作为一个新的业务形态被引入到标准中进行相关的标准化业务。NCIS业务主要针对AR/VR、游戏等应用，对速率、时延、丢包率、高速编解码等业务质量有很高的要求。例如：对于VR游戏，需要达到10Gbps速率，丢包率不可超过10E-4。针对NCIS业务建立的会话为NCIS会话，在相同NCIS会话的UE可以认为组成一个NCIS组，例如：游戏中组队。NCIS组内的UE有以下可能的通信方式，可以组合使用：
-彼此临近，例如：使用D2D技术进行广播或组播，或建立sidelink(也称为使用PC5接口)进行1对1通信(单播)；
-远离彼此，例如使用UE-网络-服务器-对端网络-对端UE(也称为使用Uu接口)。
组内的UE可以来自相同的陆上公用移动通信网(Public Land Mobile Network，PLMN)，也可以来自不同的PLMN。举例来说，一个NCIS组中有5个UE，其中3个是PLMN 1的UE，2个是PLMN 2的UE，3个PLMN 1的UE可以使用D2D技术在PC5接口互相直接通信，同时又与2个PLMN 2的UE使用网络进行通信。
UE-to-network relay系统架构如图1D，用户设备到网络中继UE-to-network relay来服务remote UE的通信，其中，SGI为核心网与分组数据网络(PacketDataNetwork，PDN)网关之间的接口，该架构能够提供更加高速、可靠等的服务。
如图1E所示的中继传输初始化信令交互流程图，包括如下步骤：
步骤1，网络侧初始附加和/或Relay UE请求PDN连接，E-UTRAN Initial Attach and/or UE requested PDN connecticity。
步骤2，中继设备与远端设备完成发现步骤，Discovery Procedure
步骤3，中继设备与远端设备完成一对一通信的连接建立，Establishment of connection For one-to-one Communication。
可选步骤3，中继设备可以建立一个新的PDN连接用于中继，Relay UE may establish a new PDN connection for Relay。
步骤4，远端设备向中继设备上报IP地址/前缀分配，IP address/prefix allocation。
步骤5，远端设备向网络侧上报远端设备报告(远端用户标识、IP地址信息)，Remote UE Report(Remote User ID,IP info)
步骤6，网络侧实体转发远端设备报告(远端用户标识、IP地址信息)，Remote UE Report(Remote User ID,IP info)。
上述过程中，可选步骤3中，relay UE为了传输remote UE的中继数据，relay UE需要使用合适的PDN connection。使用哪个PDN connection来传输中继数据由relay UE决定，一般地，relay UE可以把所有的中继数据都用一个专门的PDN connection来传输。5G架构中，relay UE会为了传输remote UE的数据建立合适的PDU session。上行数据：remote UE-》relay UE-》RAN-》5GC-》DNN-》Application server。下行反向。
为了给remote UE提供更好的服务，满足不同业务需求，例如：传输速率、时延、丢包率等，PC5 连接和relay UE的PDU session内都有QoS flow用来传输数据。不同的QoS flow支持不同的QoS需求。Relay UE怎么把PC5连接上的QoS flow和PDU session上的QoS flow匹配起来是个需要解决的问题。
针对上述问题，本申请实施例提出一种中继通信服务质量QoS保证的方法，下面结合附图进行详细说明。
针对上述问题，本申请实施例提出一种中继通信QoS保证的方法，下面结合附图进行详细说明。
请参阅图2A，图2A是本申请实施例提供的一种中继通信QoS保证的方法的流程示意图，如图所示，该方法包括：

举例来说，如果一个IP业务的端到端的QoS要求为：可靠性-10 -4，时延--30ms，那么PCF网元在PC5接口上产生的QoS要求可以为PQI＝1，Uu接口上的产生的QoS要求可以为5QI＝82。

在一个可能的示例中，所述方法还包括：所述第一设备根据所述第一QoS策略确定所述第一中继业务的所述第一QoS规则。
可见，本示例中，由第一设备确定第一中继业务的第一QoS规则，第一设备将第一QoS规则同步给第二设备，从而第一设备和第二设备确定承载第一中继业务的上行数据或下行数据的Uu接口的QoS flow。
在一个可能的示例中，所述方法还包括：所述第一设备向所述第二设备发送所述第一QoS策略，所述第一QoS策略用于所述第二设备定所述第一中继业务的所述第一QoS规则。
