发明内容
本申请实施例提供了一种数据传输的方法及装置,用以对5G V2X业务的专用服务质量QoS参数进行管理和映射,通过所述QoS参数,网络侧和用户设备侧均可以对5G V2X业务数据包进行承载映射以及传输参数处理,提高了网络实现5G V2X业务的灵活度和整体效率。

本申请实施例针对5G V2X业务,在传输数据时每个V2X业务数据包中携带QoS参数索引,通过本申请实施例所提供的方法可以在预配置的表格中根据QoS参数索引确定与之对应的QoS参数,通过该QoS参数,网络侧和用户设备(User Equipment,UE)均可以对5G V2X业务数据包进行承载映射以及传输参数等的处理,提高了网络实现5G V2X业务的灵活度和整体效率。
可选地,所述QoS参数表格通过如下方式之一预配置给用户设备UE:
标准规定;
签约数据;
广播通知;
专用信令通知。
可选地,所述QoS参数表格包括5G V2X业务专用的QoS参数和5G V2X业务专用的QoS参数索引之间的对应关系。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,并不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例提供了一种数据传输的方法及装置,用以对5G V2X业务的专用QoS参数进行管理和映射,通过所述QoS参数,网络侧和用户设备侧均可以对数据包进行承载映射以及传输参数处理,提高了网络配置的灵活度和整体效率。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
本申请实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用的系统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)通用分组无线业务(General Packet Radio Service,GPRS)系统、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系 统、LTE时分双工(Time Division Duplex,TDD)、通用移动系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WIMAX)系统、5G系统以及5G新空口(New Radio,NR)系统等。这多种系统中均包括终端设备和网络设备。
本申请实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端设备(Remote Terminal)、接入终端设备(Access Terminal)、用户终端设备(User Terminal)、用户代理(User Agent)、用户装置(User Device),本申请实施例中并不限定。
本申请实施例涉及的网络设备,可以是基站,该基站可以包括多个小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互转换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本申请实施例涉及的网络设备可以是全球移动通信系统 (Global System For Mobile Communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(Base Transceiver sSation,BTS),也可以是带宽码分多址接入(Wide-Band Code Division Multiple Access,WCDMA)中的网络设备(NodeB),还可以是长期演进(Long Term Evolution,LTE)系统中的演进型网络设备(Evolutional Node B,eNB或e-NodeB)、5G网络架构(Next Generation System)中的5G基站,也可是家庭演进基站(Home Evolved Node B,HeNB)、中继节点(elay node)、家庭基站(femto)、微微基站(pico)等,本申请实施例中并不限定。
下面结合说明书附图对本申请各个实施例进行详细描述。需要说明的是,本申请实施例的展示顺序仅代表实施例的先后顺序,并不代表实施例所提供的技术方案的优劣。
5G核心网没有承载(Bearer)的概念,它发送给下一代基站(Next Generation Node B,NG-NB)的QoS参数是以流为粒度配置的,采取5G QoS标识(5QI)方式配置,此外,由于接入网NG-NB仍然以无线承载(Radio Bearer,RB)为粒度进行QoS管理,因此接入网需要生成RB级别的QoS参数用于NG-NB与UE以及NG-NB与其他无线接入实体之间的交互过程。版本14/15的车联网LTE V2X里采取简化的PPPP和PPPR作为QoS参数传递,完成V2X QoS的各种操作。然而在5G V2X中,目前并没有成熟的QoS管理机制。本申请以下实施例提供一种通过5G V2X业务专用的QoS管理和映射方法,能够完成全部V2X参数的映射和管理,提高了网络配置的灵活度和整体效率。
实施例一,标准规定。
为了节省信令开销和降低时延,最简单的一种V2X QoS参数的定义方式是标准直接规定,具体参数配置参见图1。
本申请实施例在图1所示的QoS参数表格中并未包含优先级参数,但实际应用中可以包含此参数。
本申请实施例一将典型的V2X业务的QoS需求列出来,作为典型的QoS参数索引的取值,但实际应用中存在不止于此的V2X业务需求组合,可以根 据实际需要修改标准,定义或者更改增加新的QoS参数索引以及其对应的QoS参数。
标准化QoS参数表格的优点是简单,UE和网络侧的业务层在产生数据包时,根据数据包的特点和需求,选择合适的QoS参数(一个或多个),并将其QoS参数索引携带在数据包里,这样数据包到达任意一层,都可以通过QoS参数索引找到对应的QoS参数,从而进行相应的传输处理。
实施例二,提前通知。
当变更增加时,会影响到低版本的之前的UE不能支持后续新加的业务,因此需要对QoS参数表格进行更新,更新方式如下:
方式一,通过运营商QoS参数更新即采取签约数据的方式,UE开通V2X业务时,由签约的运营商将一些预配置的QoS参数映射表格预配置到UE中,从而UE后续可以使用这些QoS参数索引。当后续有更新时,UE可以通过运营商去更新QoS参数索引信息,当版本或者软件更新时,UE可以支持后续的新业务;
方式二,UE采用预下载的方式,在附着到网络时,查询自己是否具有最新的QoS参数表格,若没有则采取再次下载的方式,从网络侧获取最新的QoS参数表格;
方式三,网络侧可以对QoS参数表格进行广播,以便于所有V2X UE获得最新的QoS参数表格。该广播可以是点播(On demand)的方式,由UE根据需要触发获取,以降低网络开销。例如:UE发现自己没有存储任何QoS参数索引,而网络支持V2X QoS参数索引广播,则UE可以通过请求的方式,让网络广播一下该QoS参数表格;或者网络侧广播了自己的最新QoS参数表格的版本号为6,UE发现自己存储的版本为较低的4,则UE也可以请求,让网络广播一下最新的第6版本的QoS参数表格。
方式四,UE发现自己没有QoS参数表格,或者表格版本过旧时,可以通过专用信令向网络请求,由网络将最新的QoS参数表格发送给它。
一般来说,无论是哪种QoS参数表格的更新方式,均需要在前一个版本 上进行增量更新,这样可以保证之前的QoS参数是有效的,仍旧可以工作。QoS参数索引的长度可以定义为8bit(256个值)或者16bit(65536个值)等,随着业务的增多可以逐渐的升级。
实施例三,QoS参数索引的使用。
5G V2X业务与QoS参数索引之间的联系主要通过传输内容建立,根据传输内容确定传输需求从而与QoS参数索引对应。
当高层下发的所有数据包都随包携带QoS参数索引时,可以通过该QoS参数索引找到对应的所有QoS参数。一般情况下,接入网在进行数据包到数据无线承载(Data Radio Bearer,DRB)的映射时,可以将相同或者相近QoS需求的数据包映射到一个DRB上,例如:将QoS参数索引为4的所有数据包映射到一个DRB,将QoS参数索引为8的所有数据包映射到另一个DRB上;或者,当QoS参数索引为3、QoS参数索引为5对应的数据包可能都具有99.999%误块率要求和10ms时延要求,优先级分别为5和4时,可以将这两个QoS参数索引的数据包都映射到一个DRB上。当完成映射后,需要确定DRB的相关参数,例如:误块率要求90或者99的业务,其DRB可以采取非确认模式UM传输,而误块率要求高于或者等于99.999的需要采取确认模式AM传输,或者UM的重复Duplication方式传输。
此外,物理层相关的资源选择、资源抢占和重传等,也依据QoS参数索引对应的不同QoS参数进行区分处理,从而满足不同的QoS需求,最大化资源利用效率。
实施例四、QoS参数索引的使用方式通知。
由于QoS参数索引还可能在两个UE之间通信时直接使用,或者由UE上行发起的业务直接使用从而避免提前的配置过程,为了使得发送端和接收端对相同的QoS参数有相同的处理方式,即发送端对QoS参数采取的处理方式,在接收端也可以采取相同的处理方式,则需要对QoS参数索引提前配置。
例如:网络侧可以通过广播、专用信令、预配置的方式通知UE,当误块率要求高于门限99.99且时延要求低于10ms时,自动启动重复Duplication机 制。
综上所述,由于现有的V2X QoS管理机制只有PPPP和PPPR的等级配置,包含的参数比较少,且等级有限,不能完全体现不同QoS需求。虽然5G现有的QoS管理机制在QoS管理和映射上精细度较完善,但是需要提前进行信令过程配合工作,对于V2X时延要求比较高的业务不能马上进入传输,因此本申请实施例的提供一种数据传输的方法,包含适应5G V2X的QoS管理机制,参见图2,包括:
S101、从服务质量QoS参数表格中确定当前需要采用的5G V2X业务专用的QoS参数;
所述QoS参数例如图1中的有效载荷、传输速率、最大时延参数、误块率、数据速率、通信距离等。
S102、根据所述QoS参数传输数据。
可选地,所述QoS参数表格通过如下方式之一预配置给用户设备UE:
标准规定,例如按照图1中V2X QoS参数的定义方式直接规定;
当业务变更时,会影响带低版本之前的UE不能支持后续新加的业务,可以按照实施例二所述方式对QoS参数表格进行更新也可进行预配置,包括:
签约数据;
广播通知;
专用信令通知。
可选地,所述QoS参数表格包括5G V2X业务专用的QoS参数和5G V2X业务专用的QoS参数索引之间的对应关系。
所述QoS参数与QoS参数索引之间的对应关系可以是一个QoS参数索引对应一组QoS参数。
可选地,根据QoS参数索引,从服务质量QoS参数表格中确定当前需要采用的5G V2X业务专用的QoS参数。
可选地,所述5G V2X业务专用的QoS参数包括下列参数之一或组合:
业务优先级;
时延参数,其单位可以为ms;
误块率,即可靠性,单位为%;

数据速率,其单位可以为Mbps;
最小通信距离,其单位可以为米。
后续UE在发送数据包时,直接携带QoS参数索引,通过该方法根据该QoS参数索引,UE和接入网侧实体可以获知对应的QoS参数,从而对该数据包进行符合QoS需求的映射和传输处理,所述传输处理包括不同优先级的处理。
可选地,该方法还包括:更新所述QoS参数表格。
可选地,通过如下方式之一更新所述QoS参数表格:
通过运营商QoS参数更新;
当终端附着到网络时,若终端查询到网络侧有最新的QoS参数表格,则所述终端从网络侧下载最新的QoS参数表格;
通过广播更新;
通过专用信令更新。
可选地,本申请实施例所提供的方法还包括:
将所述QoS参数的索引通知给数据接收端。
例如,实施例四中QoS参数索引的使用方式通知,由于QoS参数索引还可能在两个UE之间通信时直接使用,或者由UE上行发起的业务直接使用,避免提前配置,则需发送端和接收端对相同的QoS参数有相同的处理方式,则需要对QoS参数索引提前配置。例如:网络侧可通过广播或者专用信令预配置的方式告知UE,当误块率要求高于门限99.99且时延要求低于10ms时自动启动重复Duplication机制。
本申请实施例所提供的数据传输方法在UE侧和网络侧均适用。
与上述方法相对应地,本申请实施例还提供了一种数据传输的装置,参见图3,包括:
