Description

传输数据的方法、终端设备和核心网设备 技术领域
本申请涉及通信领域,尤其涉及传输数据的方法、终端设备和核心网设备。
背景技术
在5G网络中,一个协议数据单元(Protocol Data Unit,PDU)会话(Session)可以使用多种接入技术来传输数据。例如可以既使用第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)接入技术(例如,长期演进(Long Term Evolution,LTE),新无线(New Radio,NR));又使用非3GPP(Non-3GPP,N3GPP)(例如,无线局域网(Wireless Local Area Network,WLAN))接入技术。这种PDU Session可以被称为多址(Multi-Access,MA)PDU Session。通过MA PDU Session,UE可以获得更高的传输速率,可以节约更多的资费;网络则也可以更高效地利用N3GPP的无线资源,提高传输速率。
当终端设备建立或者修改MA PDU Session时,终端设备可以在4G核心网(即演进分组数据核心网(Evolved Packet Core,EPC)或者在5G核心网(5G Core,5GC)中,使用3GPP接入技术和N3GPP接入技术建立两个路径。
若该MA PDU Session采用3GPP接入和N3GPP接入建立的两个路径都是在5GC中,那么SMF会给终端设备分配接入业务转向切换拆分(Access Traffic Steering,Switching,Splitting,ATSSS)规则(Rule),该ATSSS Rule用于终端设备决定待传输的上行数据包应该使用的接入(access)类型;另外还会分配服务质量(Quality of Service,QoS)Rule,该QoS Rule用于终端设备决定待传输的上行数据包应该使用的QoS流(Flow)。也就是,当终端设备需要传输上行数据时,终端设备可以分别使用两种规则来匹配数据。
但是,如果该MA PDU Session采用3GPP接入和N3GPP接入建立的两个路径中,一个是在5GC中,一个是在EPC中,那么此时终端设备要如何使用QoS流来传输数据是目前亟待解决的问题。

通过上述技术方案,对于终端设备跨CN建立MA PDU Session的情况,终端设备在传输上行数据时,优先使用ATSSS Rule确定接入类型,进而确定对应类型核心网的数据流,这样,当有上行数据传输时,终端设备可以合理使用ATSSS Rule和QoS参数来传输数据。

可选地,该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例,通信设备可包括具有通信功能的网络设备110和终端设备120,网络设备110和终端设备120可以为上文所述的具体设备,此处不再赘述;通信设备还可包括通信系统100中的其他设备,例如网络控制器、移动管理实体等其他网络实体,本申请实施例中对此不做限定。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
在4G和5G网络的交互(interworking)架构中,4G核心网中的公用数据网(Public Data Network,PDN)网关控制(PDN GateWay Control,PGW-C)与5G的会话管理功能(Session Management Function,SMF)在功能上基本相同,都是管理会话的网元,两个网元是共通的,可以合社,例如,可以表示为PGW-C+SMF。
图2示出了根据本申请实施例的建立MA PDU Session的示意图。如图2所示,应用客户端(Application client)控制终端设备(包括住宅网关(Residential Gateway,RG))与服务器(Server host)之间通过MA PDU Session进行通信,该MA PDU Session包括两 个路径(或者也可以成为“腿(leg)”),一个路径为采用3GPP接入技术建立的PDU Session,一个是采用N3GPP接入技术建立的PDU Session,或者说子(Child)PDU Session。
目前该MA PDU Session采用3GPP接入和N3GPP接入建立的两个路径都是在5GC中。具体地,如图2所示,对于采用3GPP接入技术建立的PDU Session,终端设备经过3GPP接入模块与用户面功能(User Plane Function,UPF)实体建立MA PDU Session,经过UPF(或者PDU会话锚点(PDU Session Anchor,PSA))到达服务器(server host);而对于采用N3GPP接入技术建立的Child PDU Session,终端设备经过N3GPP接入模块与N3GPP交互功能(Non-3GPP InterWorking Function,N3IWF),与UPF实体建立另一个Child PDU Session,再经过UPF(或PSA)到达服务器。
其中,3GPP接入模块与UPF实体之间可以通过N3接口通信,N3IWF与UPF实体之间可以通过N3接口通信,UPF与UPF(或PSA)之间可以通过N9接口通信,而UPF(或PSA)与服务器之间可以通过N6接口通信;另外,N9接口左边的UPF可以随着终端设备的移动而更换,但是N9接口右边的(或PSA)通常并不会。
建立如图2所示的两个路径时,SMF还会给终端设备分配接入业务转向切换拆分(Access Traffic Steering,Switching,Splitting,ATSSS)规则(Rule),该ATSSS Rule用于终端设备决定待传输的上行数据包应该使用的接入(access)类型;另外还会分配服务质量(Quality of Service,QoS)Rule,该QoS Rule用于终端设备决定待传输的上行数据包应该使用的QoS流(Flow)。也就是,当终端设备需要传输上行数据时,终端设备可以分别使用两种规则来匹配数据,并且,不需要限制两种规则的匹配顺序,即顺序不影响上行数据的传输。
上述MA PDU Session采用3GPP接入和N3GPP接入建立的两个路径都是在5GC中,如果两个路径一个在5GC中,而另一个在EPC中,那么可能需要为终端设备分配一套ATSSS Rule,两套QoS参数(一套对应EPC,一套对应5GC),但是当有上行数据传输时,终端设备并不知道应该使用哪套QoS参数来传输数据。因此,本申请实施例提出了一种传输数据的方法,能够解决这一问题。
图3为本申请实施例提供的一种传输数据的方法200的示意性流程图。该方法200可以由终端设备和核心网设备共同执行例如,该终端设备可以为如图1所示的终端设备设备;该核心网设备可以包括PGW-C+SMF,或者也可以为其他核心网设备,例如还可以包括SMF,本申请实施例并不限于此。
如图3所示,该方法200包括:S210,确定目标接入类型。具体地,终端设备可以在多个不同接入类型中确定上行数据的目标接入类型。例如,该不同接入类型中可以包括3GPP接入和N3GPP接入,对应的,目标接入类型可以为3GPP接入或者N3GPP接入,但本申请实施例并不限于此。
应理解,该终端设备可以通过多种方式,在该多个不同接入类型中确定上行数据的目标接入类型。例如,该终端设备可以根据接入业务与接入类型的对应关系,在多个不同接入类型中,确定待传输的上行数据对应的目标接入类型。其中,该接入业务与接入类型的对应关系可以包括ATSSS规则。即终端设备可以根据ATSSS规则,确定目标接入类型。
在该S210之前,该方法200还可以包括:终端设备接收核心网设备发送的ATSSS规则,该ATSSS规则用于指示目标接入类型,以便于终端设备确定目标接入类型。
如图3所示,该方法200还包括:S220,确定目标接入类型对应的目标类型核心网。具体地,该终端设备可以根据接入类型与核心网类型之间的对应关系,确定该目标接入类型对应的目标类型核心网。
应理解,图4示出了根据本申请实施例的传输数据的方法200的另一示意图,如图4所示,该方法200还可以包括:S240,发送对应关系指示信息。具体地,核心网设备向终端设备发送对应关系指示信息,该对应关系指示信息用于指示不同接入类型(access type) 和核心网(Core Network,CN)类型(Type)之间的对应关系。
为了便于后面说明,这里以该对应关系包括如下关系为例进行说明:第一类核心网对应于第一接入类型、以及第二类核心网对应于第二接入类型,其中,第一类核心网和第二类核心网可以相同,也可以不同;第一接入类型和第二接入类型可以相同,也可以不同。
例如,该第一类核心网可以为EPC或者5GC,该第二类核心网也可以为EPC或者5GC;而该第一接入类型可以为3GPP或者N3GPP,该第二接入类型也可以为3GPP或者N3GPP。
例如,该第一类核心网为EPC时,该第二类核心网可以为5GC。
再例如,该第一类核心网为5GC时,该第二类核心网也可以为5GC,此时,对应的该第一接入类型可以为N3GPP,该第二接入类型可以为3GPP。
应理解,作为一个实施例,这里以该第一类核心网和第二类核心网不同,且第一接入类型和第二接入类型也不同为例进行说明。例如,第一类核心网为EPC,其对应的第一接入类型为3GPP,且第二类核心网为5GC,其对应的第二接入类型为N3GPP;或者,第一类核心网为EPC,其对应的第一接入类型为N3GPP,且第二类核心网为5GC,其对应的第二接入类型为3GPP,但本申请实施例并不限于此。
应理解,终端设备如果之前已经在5GC注册过,则终端设备中会有网络下发的用户路径选择策略(UE Route Selection Policy,URSP),在该URSP中可以包括该对应关系指示信息,也可以说是通过该URSP指示每个access type对应的CN Type。例如,终端设备可以根据URSP确定3GPP和N3GPP应该分别使用的CN type。
可选的,该URSP可以包括其他信息,例如,该URSP还可以用于指示接入类型偏好(Access Type Preference),本申请实施例并不限于此。
在本申请实施例中,终端设备可以根据接收到核心网设备发送的对应关系指示信息,建立PDU Session。由于这里以采用3GPP和N3GPP两种接入类型为例,所以这里的PDU Session即为MA PDU Session,为了区分,下文中均称为MA PDU Session。具体地,终端设备根据该对应关系指示信息,建立MA PDU Session可以具体包括S250和S260。
如图4所示,该方法200还可以包括:S250,在第一类核心网中建立第一路径。具体地,该终端设备通过该第一接入类型,在该第一类核心网中,建立该MA PDU Session的第一路径。
为了便于说明,这里以该第一类核心网为EPC为例进行说明,则该终端设备通过该第一接入类型,在该EPC中,建立该MA PDU Session的第一路径,其中,该第一接入类型可以为3GPP(例如,演进的通用移动通信系统(Universal Mobile Telecommunication System,UMTS)陆地无线接入(Evolved-UMTS Terrestrial Radio Access,E-UTRA))或N3GPP。
具体地,终端设备在EPC建立PDN连接(Connection),这个PDN Connection对应MA PDU Session中的第一路径。可选的,该终端设备可以与核心网设备中的UPF网元在EPC建立该PDN connection。
应理解,在终端设备建立该PDN connection的过程中或者之后,该方法200还包括:终端设备建立演进分组系统(Evolved Packet System,EPS)承载(Bearer)。具体地,终端设备在EPC建立EPS Bearer时,可以同时接收到EPS Bearer上下文(context)以及对应的5G的QoS Flow Context,但是终端设备只使用EPS Bearer Context,而不使用QoS Flow Context,也就是只使用EPS Bearer。
应理解,该方法200还可以包括:终端设备接收核心网设备(例如,PGW-C+SMF)发送的第一QoS参数集合,该第一QoS参数集合包括该第一路径的至少一个第一数据流的QoS参数。例如,若第一类核心网为EPC,这里的第一数据流即为EPS Bearer。
可选的,该第一QoS参数集合中还可以包括与该EPS Bearer对应的5G的QoS Flow的QoS参数。
在本申请实施例中,EPS Bearer与其对应的QoS Flow可以使用相同或者不同的分组过 滤(Packet Filter,PF)规则,例如,该EPS Bearer的PF规则可能大于或者说多于QoS Flow的PF规则。当用上行数据需要传输时,可以按照该EPS Bearer的Packet Filter规则,过滤该待传输的上行数据。
如图4所示,该方法200还可以包括:S260,在第二类核心网中建立第二路径。具体地,该终端设备通过第二接入类型,在该第二类核心网中,建立该MA PDU Session的第二路径。
在上述S250中,以第一类核心网设备为EPC为例进行说明,则这里S260以第二类核心网为5GC为例进行说明,则终端设备通过第二接入类型,在该5GC中,建立该MA PDU Session的第二路径。其中,该第二接入类型为3GPP或N3GPP,例如,第一接入类型为3GPP,第二接入类型为N3GPP。
具体地,终端设备在5GC建立PDU Session,这个PDU Session对应MA PDU Session中的第二路径。可选的,该终端设备可以与核心网设备中的UPF网元在5GC建立该PDU Session。
应理解,在终端设备建立该PDU Session的过程中或者之后,该方法200还包括:终端设备建立QoS Flow。具体地,终端设备在5GC建立QoS Flow时,会接收到QoS Flow Context。
应理解,该方法200还可以包括:终端设备接收核心网设备(例如,PGW-C+SMF)发送的第二QoS参数集合,该第二QoS参数集合包括该第二路径的至少一个第二数据流的QoS参数。例如,若第二类核心网为5GC,这里的第二数据流即为QoS Flow。
可选的,核心网设备可以在该第二QoS参数集合中仅发送需要更新或增加的QoS Flow的QoS参数。具体地,由于第一QoS参数集合中可以包括有QoS Flow的QoS参数,因此,PGW-C+SMF可以在第二QoS参数集合中不发第一QoS参数集合中已发过的,只发需要更新或增加的QoS Flow参数。即该第二QoS参数集合中可以不包括第一QoS参数集合中包括的QoS参数,则终端设备根据该第一QoS参数集合和该第二QoS参数集合,确定该至少一个第二数据流的QoS参数。也就是终端设备将第一QoS参数集合与第二QoS参数集合中的QoS Flow参数合并在一起,共同作为应用于5GC的QoS Flow的QoS参数。
可选的,核心网设备也可以在该第二QoS参数集合中包括全部QoS Flow的QoS参数,即不区分是否在第一QoS参数集合中是否已经发送过,则终端设备根据该第二QoS参数集合,即可确定5GC下的QoS Flow的QoS参数。
可选的,在终端设备完成上述第一路径和第二路径建立之前,该方法200还可以包括:该终端设备向该核心网设备发送能力信息,该能力信息用于指示该终端设备支持建立该第一路径和该第二路径。具体地,终端设备可以通过该能力信息告知PGW-C+SMF自己是否支持使用EPC和5GC建立MA PDU Session。
如果能力信息指示终端设备支持第一路径和第二路径的建立,则该方法200还可以包括:该终端设备接收该核心网设备根据该能力信息发送的响应信息,该响应信息用于指示该核心网设备允许该终端设备建立该第一路径和该第二路径。具体地,PGW-C+SMF可以根据接入点名称(Access Point Name,APN)和本地配置等信息,判断是否允许使用上述interworking模式,并通知该终端设备。例如,该响应信息可以为任意参数,通过该参数指示允许终端设备建立第一路径和第二路径。
如图3或者图4所示,该方法200还可以包括:S230,发送上行数据。具体地,该终端设备采用目标类型核心网对应的至少一个数据流,发送该上行数据,例如该终端设备可以向核心网设备包括的SMF发送该上行数据。终端设备根据上述各个步骤,建立第一路径以及对应的至少一个第一数据流,建立第二路径以及对应的至少一个第二数据流。当终端设备需要传输上行数据时,终端设备可以优先根据ATSSS Rule,确定该上行数据使用的access type为目标接入类型,再使用对应该目标接入类型的目标类型核心网的Packet Filter, 在该目标类型核心网对应的至少一个数据流中确定上行数据使用的数据流。
例如,目标接入类型为第一接入类型,则目标类型核心网为第一类核心网,传输上行数据的数据流为第一数据流。
再例如,终端设备根据ATSSS Rule确定目标接入类型为3GPP接入,而假设与该3GPP接入对应的目标类型核心网为EPC,则终端设备使用EPC的EPS Bearer Context中的PF,过滤待传输的上行数据,即通过EPS Bearer传输该上行数据。
其中,ATSSS Rule可以在上述任何流程中发给终端设备,例如,可以在执行S250和S260过程中、过程之前或者过程之后,以用于终端设备确定目标接入类型。
应理解,考虑到一个PDU Session中可以有一个或多个QoS Flow,该QoS Flow可以分为保证比特速率(Guaranteed Bit Rate,GBR)和非GBR(Non-GBR)两种类型;类似的,一个PDN Connection中可以有一个或多个EPS Bearer,该EPS Bearer也可以分为Non-GBR和GBR两种类型。
根据现有标准规定,MA PDU Session建立的两个路径均在5GC中,而MA PDU Session的GBR QoS Flow只可以使用一个路径,也就是说只有一边的接入网(Access Network,AN)上有QoS Flow的上下文。当GBR QoS Flow需要更换access类型时,PGW-C+SMF通知新AN建立用户面资源,让旧AN释放用户面资源。
类似的,本申请实施例的GBR数据流也可以使用一个路径。考虑到在EPC建立EPS Bearer时,终端设备接收并保存EPS Bearer Context时,还会收到并保存该EPS Bearer对应的QoS Flow Context,但是终端设备只是用EPS Bearer Context。因此,在GBR数据流从EPC转到5GC时不需要删除对应的QoS Flow Context,而在从5GC转到EPC时,可以删除QoS Flow Context。
具体地,对于至少一个第一数据流中包括的GBR数据流,这里称为第一GBR数据流,该方法200还包括:该终端设备以及核心网设备删除该第一GBR数据流的上下文,以及保留该第一GBR数据流对应的第二数据流上下文,该第二数据流上下文为终端设备在建立或修改该第一GBR数据流时获得的。
可选的,该方法200还可以包括:该终端设备接收该核心网设备发送的第一指示信息;该终端设备根该第一指示信息,保留该第二数据流上下文。
例如,假设第一GBR数据流为GBR EPC Bearer,若PGW-C+SMF指示终端设备将一个GBR EPC Bearer从EPC转到5GC,PGW-C+SMF和终端设备可以将EPC中对应的Dedicated Bearer释放,即删除EPC Bearer Context。但是终端设备和PGW-C+SMF都不删除该EPC Bearer对应的QoS Flow的QoS Flow Context。
可选的,对于至少一个第二数据流中包括的GBR数据流,这里称为第二GBR数据流,该方法200还包括:该终端设备以及核心网设备删除该第二GBR数据流的上下文,另外,终端设备还会保存接收到的该核心网设备发送的第二GBR数据流对应的第一数据流上下文。
可选的,该方法200还可以包括:该终端设备接收该核心网设备发送的第二指示信息;该终端设备根据该第二指示信息,删除该第二GBR数据流的上下文。
例如,假设第二GBR数据流为GBR QoS Flow,若PGW-C+SMF将一个GBR QoS Flow从5GC转到EPC,PGW-C+SMF在5GC将QoS Flow释放,终端设备和PGW-C+SMF删除该QoS Flow的QoS Flow Context;并在EPC建立该GBR EPS Bearer时,终端设备会接收和保存EPS Bearer Context以及其对应的QoS Flow Context,但是终端设备只是用EPS Bearer Context。
因此,本申请实施例的传输数据的方法,对于终端设备跨CN建立MA PDU Session的情况,终端设备在传输上行数据时,优先使用ATSSS Rule确定Access type,再使用QoS Rule确定对应的QoS Flow,这样,当有上行数据传输时,终端设备可以合理使用ATSSS  Rule和QoS参数来传输数据;同时,还明确了终端设备和PGW-C+SMF对GBR QoS Flow在EPC和5GC间转移的流程。
应理解,在本申请的各种实施例中,上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
另外,本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
