相关申请的交叉引用
本申请要求在2021年12月31日提交的中国专利申请第202111676460.2号的优先权,该中国专利申请的全部内容通过引用包含于此。
技术领域
本申请属于无线通信技术领域,具体涉及一种数据传输方法、装置及终端。
背景技术
在第三代合作计划(3rd Generation Partnership Project,3GPP)协议中,当终端上的应用有流量要发送的时候,应用可以提供待发送的应用流量的流量特征,终端(OS操作系统或modem芯片)获取应用提供的流量特征,例如,待发送的应用流量的目的IP地址、全限定域名(Fully Qualified Domain Name,FQDN)等。终端会将该流量特征与终端中的用户设备路由选项策略(UE Route Selection Policy,URSP)规则中的流量描述符(Traffic Descriptor,TD)参数进行匹配,匹配到某个流量描述符以后,然后终端再选择该流量描述符下的某个路由选择描述符(Route Selection Descriptor,RSD)。该流量描述符中定义了,当应用流量特性同某流量描述符匹配以后,用于承载待传输的应用流量的PDU会话的会话参数。如果当前UE已经有一个PDU会话,且该PDU会话的会话参数同终端为应用流量所选择的流量描述符下的某个RSD一致,那么可以将该应用的待传输数据路由至已建立的协议数据单元(Protocol Data Unit,PDU)会话。或者,如果终端为待传输的应用流量选择了该流量描述符下的某个RSD以后,而当前终端内不存在这样的PDU会话,那么终端可以触发新PDU会话的建立,所建立的PDU会话的会话参数,同选择的RSD内的PDU会话参数一致,并使用该PDU会话承载所述待传输的应用数据流。
然而,在相关技术中,目前URSP规则中的流量描述符一般包括目的IP地址、FQDN等,这些流量描述符只能针对特定的应用流量的特征来进行选择PDU会话承载,比如,特定的IP地址或FQDN,为了确保对每个应用的流量都有URSP规则,那么网络侧需要发送多个URSP规则到终端。但本申请的发明人发现,对于终端上的各类应用和各类应用 待发送的应用流量,可能具有一定的共性,比如,应用1待发送的流量和应用2待发送的流量都属于游戏类业务,这些业务的应用流量具有类似的特性,可以使用同一种URSP规则进行流量匹配,或,选择相同的PDU会话进行承载,如果采用当前URSP规则的设计,则流量匹配效率较低,且不利于运营商按照业务类别进行管理。

在一个可能的实现方式中,由于同一业务类型的数据流,可能所需的PDU会话承载也可能不同,例如,考虑到即便都是video视频业务流,但不同的应用程序所需的PDU session承载也可能是不同的,终端可能会进行差异化处理。因此,在该可能的实现方式中,URSP规则中还包括:同一业务类型下,流量描述参数与RSD的第二映射关系和/或业务性能描述参数与RSD的第三映射关系。
例如,在表5中,一个流量分类(Traffic categories)描述符关联的第一映射关系中,对于同一业务类型,还可以设置流量描述参数(例如,DNN,APP descriptor,或者IP三元组等)与RSD的第二映射关系。

(7)一个或多个业务服务器的算力;例如,URSP规则中记录业务服务器的算力=10台服务器对应的RSD为RSD2;由于所述待发送的流量,需要发送至特定的服务器进行处理,那么该参数表示,终端应用待发送流量或待发送业务,为了保证一定的业务性能和业务体验,对服务器端的算力有一定的要求。
(8)一个或多个业务服务器的算力范围。例如,URSP规则中记录业务服务器的算力>10台服务器对应的RSD为RSD3。

S212,基于所述URSP规则,对应用程序的待发送数据流(data traffic或application traffic,也可以称为数据流量,或应用流量)进行传输。
在本申请实施例中,终端可以基于URSP规则,对应用程序的待发送数据流进行匹配,根据匹配结果,选择已建立的PDU会话承载所述待发送数据流,或者新建一个PDU会话承载所述待发送数据流。
在一个可能的实现方式中,S212可以包括下面的步骤1至步骤4。
步骤1,终端获取应用程序提供的流量特征参数。
例如,终端上的应用程序在需要进行流量发送时,可以向终端(例如,终端的操作系统)发送流量特征参数。
在本申请实施例中,流量特征参数用于描述应用程序待发送的流量(即待发送数据流)的特征。例如,该流量描述参数可以包括以下至少之一:
(1)第一指示信息。所述第一指示信息用于指示待发送数据流的业务类型。例如,第一指示信息可以指示待发送数据流的业务类型为视频类业务、或游戏类业务、可企业类业务等。其中,应用的业务类型可以由运营商制定。运营商可以同APP提供方进行签约,将该应用的应用流量归类到某一个业务类型中。终端上应用程序有流量要发送时,应用程序可指示该流量从属的业务类型。
(2)目标流量描述参数。
应用可以提供待发送流量的描述参数,可选地,应用程序提供的目标流量描述参数可以包括以下至少之一:
a)目的IP信息,例如,IP三元组,或者,目的IP地址段信息。
例如,目标流量描述参数可以为:目的IP=10.1.1.1,端口号=80流量,指示流量的目的地址信息。
b)全限定域名(FQDN)信息,或者,含通配符的FQDN信息。
例如,目标流量描述参数可以为:FQDN=aaa.com,指示流量需要发送到aaa.com。
c)数据网络名称(Data Network Name)。
例如,目目标流量描述参数也可以为DNN=DNN 1,指示流量需要发送到DNN 1。
(3)目标业务性能描述参数。目标业务性能描述参数用于指示应用程序发送流量的业务诉求。
通常应用程序的待发送数据流,对通信网络具有一定的诉求,比如,该数据流所需的通信带宽、所需的最短端到端时延等。因此,应用程序可以为其待发送数据流指示出业务性能描述参数。对于不同APP提供的业务,如果这些业务的性能参数近似,则终端可以使用URSP规则选择相同的PDU会话进行承载或传输。
可选地,所述目标业务性能描述参数包括以下至少之一:
(1)分辨率;如果待发送的应用流量为视频类业务,那么可指示应用程序待发送的流量的分辨率。例如,应用程序提供的流量特征参数中可以包括:分辨率=1080P高清视频。
(2)带宽;指示应用程序待发送的流量需求的带宽。例如,应用程序提供的流量参数中可以包括:带宽=200M。
(3)端到端的时延;指示应用程序待发送的流量对时延的要求。例如,应用程序提供的流量参数中可以包括:端到端时延=40ms。如果应用程序所指示的时延要求比较高,比如,都需要低时延传输,则所选择承载该应用流量的PDU会话也应该有较低的端到端时延保障。
(4)业务服务器的算力。指示应用程序对业务服务器的算力的要求。例如,应用程序提供的目标业务性能描述参数中可以包括:10台服务器。
步骤2,终端根据所述流量特征参数,确定所述待发送数据流的目标业务类型。
在一个可能的实现方式中,根据所述流量特征参数,确定所述待发送数据流的目标业务类型,可以包括以下之一:
(1)根据所述第一指示信息,确定待发送数据流的目标业务类型;即在流量特征参数中包括第一指示信息的情况下,直接根据该第一指示信息可以确定待发送数据流的目标业务类型。
(2)根据预先设置的流量描述参数与业务类型的对应关系,确定与所述目标流量描述参数对应的所述目标业务类型。例如,在流量特征参数中不包括第一指示信息的情况下,可以根据流量特征参数中包括的目标流量描述参数确定目标业务类型。
在本申请实施例中,终端内部可以存储一个流量描述参数与业务类型的对应关系,终端可以根据该映射关系,根据终端上的应用程序所提供的待发送流量的目标流量描述参数,转换成所对应的业务类型。比如,当终端上应用待发送流量,其流量特征为:目的IP=10.1.X.X以及IP=100.1.X.X的时候,这时候终端可以具备这样的能力,将这两个待发送流量都映射或识别成:游戏类业务。从而建立了待发送流量和所述业务类型之间的关系。
(3)根据预先设置的业务性能描述参数与业务类型的对应关系,确定与所述目标业务性能描述参数对应的所述目标业务类型。
在本申请实施例中,终端内部可以存储一个业务性能描述参数与业务类型的对应关系,终端可以根据该映射关系,根据终端上的应用程序所提供的待发送流量的目标业务性能描述参数,转换成所对应的业务类型。比如,当终端上应用待发送流量,其流量的业务性能 描述参数为:端到端的时延为40ms的时候,这时候终端可以具备这样的能力,将这发送流量映射或识别成:视频类业务。从而建立了待发送流量和所述业务类型之间的关系。
也就是说,在一个可能的实现方式中,应用程序可以直接提供第一指示信息,终端根据该第一指示信息可以直接确定应用程序待发送的流量的目标业务类型。或者,在另一个可能的实现方式中,应用程序也可以不提供第一指示信息,而是指示业务性能描述参数,而终端内存有业务性能描述参数与业务类型的映射关系。在这种情况下,终端可以根据预先设置的业务性能描述参数与业务类型的映射关系,确定与所述目标应用待发送流量所对应的所述目标业务类型。或者,应用程序还指示待发送流量的流量描述参数,而终端内存在一个业务性能描述参数与业务类型的映射关系。在这种情况下,终端可以根据预先设置的流量描述与业务类型的映射关系,确定与所述待发送数据流所对应的所述目标业务类型。
例如,对于流量描述参数来说,可以在终端内预先设置这样的映射关系,比如:当待发送的应用流量,其FQDN为:FQDN=v.aaa.com、www.bbb.com的时候,这些应用流量将被映射为video类业务。或者,当待发送的应用流量,其目的IP属于192.168.X.X,比如:192.168.0.1和192.168.0.2的时候,终端可以识别这一组IP地址所对应的应用流量,为同一个企业的APP业务,比如都是本地的企业A办公网的流量,即目标IP属于192.168.X.X的业务为企业类业务。通过这些设置,可以将根据应用程序提供的目标通配符描述信息,确定应用程序从属的目标业务类型。
再例如,对于目标业务性能描述参数来说,可以在终端内预先设置这样的映射关系,比如:当所述应用待发送流量,其流量性能参数为:带宽200M或视频分辨率为1080P,那么终端可以识别为,这类业务都属于视频类业务(也可以细分成小类,比如:1080P的视频),然后,终端再根据视频类业务的特点,选择满足业务性能的PDU会话进行承载。
在一个可能的实现方式中,URSP规则中可以记载有流量分类描述符,以及流量分类描述符与第一映射关系的关联关系,如表1和表2所示。
因此,在一个可能的实现方式中,根据预先设置的流量描述参数与业务类型的对应关系,确定与所述目标流量描述参数对应的所述目标业务类型,可以包括:从所述URSP规则中获取与所述流量特征参数匹配的目标流量分类描述符,从所述目标流量分类描述符关联的第一映射关系中获取与所述目标流量描述参数对应的所述目标业务类型。例如,终端 根据应用程序提供的流量特征参数匹配到表2的流量分类描述符,则从该流量分类描述符关联的RSD中,获取与所述目标流量描述参数对应的所述目标业务类型。
在一个可能的实现方式中,根据预先设置的业务性能描述参数与业务类型的对应关系,确定与所述目标业务性能描述参数对应的所述目标业务类型,可以包括:从所述URSP规则中获取与所述流量特征参数匹配的目标流量分类描述符,从所述目标流量分类描述符关联的第一映射关系中获取与所述目标业务性能描述参数对应的所述目标业务类型。
步骤3,选择所述URSP规则中与所述目标业务类型匹配的目标RSD。
在一个可能的实现方式中,在步骤3,终端根据所述URSP规则中的业务类型与RSD的第一映射关系,选择与所述目标业务类型匹配的目标RSD。
例如,UE上的APP如果有APP traffic待发送,则APP可以标记该APP traffic的业务类别,即:标记这个流量的Traffic categories是video,gaming还是enterprise等。假设这个APP待发送的流为video的数据流,则终端可以直接识别出该业务类型,并将该流量使用URSP rules中的traffic categories匹配,匹配到video业务类。在traffic categories下可以有RSD,比如,在表4中,在traffic categories下设定一个video子类,该子类下对应RSD,比如:SSC mode=3,S-NSSAI=S-NSSAI-a。则,终端可以选择这个RSD,把所有video相关的视频流,全都使用该RSD所对应某PDU session来承载。
在一个可能的实现方式中,在步骤3中,终端还可以从所述URSP规则中获取与所述流量特征参数匹配的目标流量分类描述符,根据所述目标流量分类描述符关联的第一映射关系,选择与所述目标业务类型匹配的目标RSD。例如,在URSP规则中记录流量分类描述符,所述流量分类描述与所述第一映射关系存在关联关系的情况下,终端可以先从所述URSP规则中获取与所述流量特征参数匹配的目标流量分类描述符,再从目标流量分类描述符关联的第一映射关系中选择与所述目标业务类型匹配的目标RSD。
由于同一类业务流,可能所需的PDU会话承载也可能不同,因此,在另一个可能的实现方式中,在步骤3中,终端可以根据目标业务类型,结合应用程序提供的目标流量描述参数配置对应的RSD。因此,在该可能的实现方式中,步骤2可以包括:在所述URSP规则中匹配到所述目标业务类型,从所述目标业务类型下的流量描述参数与RSD的第二映射关系中,选择与所述目标流量描述参数匹配的目标RSD。
例如,考虑到即便是同类型的video视频业务流,可能所需的PDU session承载也是不同的。所以,在匹配了Traffic categories或者业务类型以后,还可以使用上述的Traffic descriptor,比如DNN,APP descriptor,或者IP三元组等进行匹配。这种情况,如表5所示,相当于在traffic categories下,又二次进行traffic descriptor的使用。
举例说明,假如,UE中的APP 1有traffic要发送,同时标记traffic categories=video,然后提供这个流量需要被发送到的目的IP:10.1.1.1。则URSP rules首先发现这是video类的流量,匹配到了Traffic categories=video下面,然后,URSP规则中在Traffic categories=video的下面还进行了以下描述:
-IP三元组=10.1.1.1的时候,使用RSD1或RSD2;
-FQDN=aaa.com的时候,使用RSD3;
-DNN=DNN1的时候,可使用RSD1,RSD2,RSD3。
因此,相当于匹配了traffic categories以后,再使用一次traffic descriptor,这样的目的,是为了区分,即便都是video的视频流,也可以使用不同的PDU session去承载。例如,上述APP 1匹配到的目标RSD可以为RSD1或RSD2。
或者,也可以直接对相同的video流,直接选择RSD,这样属于无差别承载,即,对于视频流都可以使用RSD=1所对应的PDU session进行承载。
另外,由于同一类业务流,不同的业务流对网络的承载需求可能不同,因此,在一个可能的实现方式中,选择所述URSP规则中与所述目标业务类型匹配的目标RSD,可以包括:在所述URSP规则中匹配到所述目标业务类型,从所述目标业务类型下的业务性能描述参数与RSD的第三映射关系中,选择与所述目标业务性能描述参数匹配的目标RSD。
例如,即便是video视频其视频流或者应用流,不同视频流或应用流由于业务性能描述参数的不同,从而导致对网络的承载的需求也是不一样的。
例如,APP1的视频流的分辨率是1080P,对带宽的诉求是200M;而APP2的视频流的分辨率4K的,对带宽诉求是500M,端到端时延希望小于30ms。因此,当APP的traffic有具体的业务特征描述的时候,在进行具体的PDU session匹配的时候或者选择时,需要进行差异对待。
假如,UE的APP 1有traffic待发送,APP 1标记traffic categories=video,然后提供 这个流量的几个业务诉求:
-1080P:分辨率
-带宽:200M
-端到端时延40ms
-业务服务器的算力:10台服务器等。
则,终端可以首先根据自身终端能力,根据业务性能描述参数,将该应用数据流进行映射,得到该应用数据流所属的业务类型;或者,终端也可以直接根据应用发送的指示信息,得到该待发送的数据流是video。则终端将该应用数据流,使用URSP rules匹配到了Traffic categories=video下面,然后,URSP规则根据traffic对网络的具体要求,还可以在Traffic categories=video下面描述:
-时延小于40ms,可使用RSD1或RSD2对应的PDU session;
-1080P的视频,可使用RSD1,RSD2,RSD3;
-带宽方面,RSD1对应的PDU会话支持400M,RSD2对应的PDU会话支持200M,RSD3对应的PDU会话支持500M;
-算力:给出不同的RSD对应的PDU session的算力,或所述PDU会话连接的业务服务器端的算力情况。
则对于上述APP1的待发送流量,RSD1或者RSD3对应的PDU session可以被选择,承载APP1的traffic。因此,终端还具备这样的能力:根据应用待发送流量的业务性能描述参数,除了先将流量进行业务类别的映射,还可以将其映射或者归类到适合使用的PDU session进行传输,即对应到具体的RSD。
步骤4,使用与目标RSD对应的协议数据单元PDU会话传输所述待发送数据流。
在一个可能的实现方式中,可以从已建立的PDU会话中选择目标PDU会话承载所述应用程序的待传输数据,其中,所述目标PDU会话为与所述目标RSD对应的PDU会话。例如,如果已建立的PDU会话中存在有与目标RSD对应的PDU会话,则可以选择已建立的PDU会话中与目标RSD对应的PDU会话传承所述应用程序的待传输数据。例如,应用程序的目标RSD包括RSD1和RSD2,终端已建立与RSD1对应的PDU会话,则选择该PDU会话承载应用程序的待传输数据,从而可以节约PDU会话资源。通常,RSD 里包含的,主要是PDU会话的一些参数或者属性,比如:SSC连接模式,DNN,S-NSSAI等等。当终端使用URSP规则,选择了RSD,则意味着,要使用终端内,包含该RSD中描述PDU会话的属性的PDU会话承载应用流量。
或者,也可以新建与目标RSD对应的PDU会话承载所述应用程序的待传输数据。例如,如果已建立的PDU会话中没有与目标RSD对应的PDU会话,则可以使用所述目标RSD中包含的PDU会话参数,新建与目标RSD对应的PDU会话传承所述应用程序的待传输数据。
