Description

用于上行和下行的数据传输的方法和装置 技术领域
本申请涉及通信领域，尤其涉及用于上行和下行的数据传输的方法和装置。
背景技术
在第五代(5th generation，5G)系统中，对于任意一个终端设备(User Equipment，UE)，5G核心网设备(5G Core，5GC)可以建立一个或者多个协议数据单元(Protocol Data Unit，PDU)会话(session)，每一个PDU session在通过空口传输时，会有一个或者多个数据无线承载(Data Radio Bearer，DRB)相对应并用于承载其数据。在PDU session中，服务质量(Quality of Service，QoS)的最小颗粒度可以区分为不同的QoS流(flow)，一个PDU session可以有多个QoS flow，不同QoS flow可以通过不同的QoS flow标识(QFI)进行标识。在一个PDU session中，同一个QoS flow中的数据会有相同的QoS处理，比如调度等等。
包括QFI的数据包在从5GC传输到接入网设备(Radio Access Network，RAN)的时候，会在N3接口中给每一个数据包进行标识，这个QFI通常为7bit。具体地，N3接口的QFI可以动态的显式分配，例如在数据包的包头部分携带该QFI，或者，也可以隐式的分配，例如令QFI等于5QI。5QI可以用于表示的QoS flow属性，例如优先级等，跟5G的QoS特征之间存在一对一的映射关系。由于目前5QI最大值为79，因此对应的需要QFI为至少7bit。
但是，终端设备中的一个PDU session在任意时刻最多支持64个服务质量流(QoS flow)，在RAN侧通过空口传输的QFI为6bit。因此，在N3接口传输的QFI为7bit，传输至到RAN侧QFI只能为6bit，两者之间存在不匹配的问题。

应理解，本申请实施例的数据包可以为互联网协议(Internet Protocol，IP)包，该数据包的包头可以为GTP包头。
在本申请实施例中，核心网设备通过接入网设备向终端设备发送数据包。具体地，在S110中，该核心网设备确定标识目标QoS flow的第一QFI，例如，该第一QFI可以为7bit，而接入网设备和终端设备之间仅支持6bit的QFI的传输，因此，该核心网设备可以根据映射规则，确定该第一QFI对应的第二QFI，通过映射，改变原QFI的比特数，即该第一QFI占用的比特数大于第二QFI占用的比特数，例如，该第一QFI为7bit，该第二QFI为6bit。
应理解，该第一QFI表示目标QoS flow，同时也可以用于表示该目标QoS flow的属性，例如，该第一QFI等于5QI的值。目前，该5QI的值的最大值为79，因此，需要7bit来表示，因此该第一QFI可以为7bit，但本申请实施例并不限于此。
可选地，该映射规则可以包括：在该第一QFI为超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系。具体地，该第一QFI占用的比特数可以大于第二QFI占用的比特数，即该第一QFI表示的最大值大于第二QFI的最大值，若该第一QFI的值超出该QFI的表示范围，则该映射规则可以为该第一QFI与该第二QFI的特定的值之间的映射关系，该第二QFI的特定值即在该第二QFI表示范围以内的值。
例如，假设第一QFI占用7bit，即该第一QFI可以表示0至127共128个值；假设第二QFI占用6bit，则该第二QFI可以表示0至63共64个值，则该第一QFI表示的值大于63时，该第一QFI的值均超过该第二QFI的表示范围，此时，该映射规则可以为：对于第一QFI为超过第二QFI的表示范围的值时，第一QFI与第二QFI的特定的值之间的映射关系。例如，根据现有的5QI的值，该第一QFI可以取{65,66,69,70,75,79}，这几个值均超过第二QFI的表示范围，取该第二QFI的几个特定值，例如，取目前5QI未占用的值，即取{10,11,12,13,14,15}，建立二者之间的对应关系，即该映射规则可以包括：{65-10,66-11,69-12,70-14,75-14,79-15}，其中，“-”表示前后两个数值之间的对应关系，例如，若第一QFI取65，即通过7bit表示该65，根据上述映射关系，确定与该第一QFI对应的第二QFI为10，即第一QFI为通过7bit表示的65与第二QFI通过6bit表示的10之间具有对应关系。
可选地，该映射规则还可以包括：在该第一QFI为未超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系。具体地，该第一QFI占用的比特数可以大于第二QFI占用的比特数，即该第一QFI能够表示的最大值大于第二QFI的最大值，该第一QFI的值可能未超出该QFI的表示范围，则该映射规则可以为该第一QFI与该第二QFI的特定的值之间的映射关系。
例如，仍然以上述第一QFI占用7bit以及第二QFI占用6bit为例进行说明，若第一QFI取值在第二QFI的表示范围之内，例如，该第一QFI取8，即通过7bit表示8，对应的，存在一个第二QFI的值与其对应，例如，第二QFI也为8，即通过6bit表示该数值8，或者该第二QFI也可以为除8以外的其它特定的数值，例如第一QFI为8时对应第二QFI为13，即第一QFI为7bit表示的数值8时与第二QFI的通过6bit表示的数值13之间具有对应关系，但本申请实施例并不限于此。
在S120中，核心网设备向接入网设备发送数据包，例如，通过N3接口向接入网设备发送该数据包，该数据包的包头包括该第二QFI，以便于该接入网设备接收该数据包，并向终端设备发送该数据包，则终端设备根据该数据包包头中的第二QFI以及映射规则，确定对应的第一QFI。
应理解，该方法100还可以包括：该核心网设备向终端设备发送NAS信令，该NAS信令用于指示映射规则，以便于终端设备根据该映射规则，确定第二QFI对应的第一QFI。
因此，本申请实施例的用于下行数据传输的方法，核心网设备根据映射规则，确定第一QFI对应的第二QFI，其中，该第二QFI占用的比特数可以小于该第一QFI占用的比特数，向接入网设备发送包括该第二QFI的数据包，以便于接入网设备将该数据包发送至终端设备，终端设备根据其中的第二QFI以及映射规则，确定对应的第一QFI，使得核心网设备、接入网设备以及终端设备之间顺利传输QFI，解决了通过N3接口传输QFI和通过空口传输QFI时QFI占用的比特数不匹配的问题。
上文中结合图1，从核心网设备的角度详细描述了根据本申请实施例的用于下行数据传输的方法，下面将结合图2，从接入网设备的角度描述根据本申请实施例的用于下行数据传输的方法。
图2示出了根据本申请实施例的用于下行数据传输的方法200的示意性流程图，该方法200可以由接入网设备执行。如图2所示，该方法200包括：S210，接入网设备接收核心网设备发送的第一数据包，该第一数据包包括第一QFI；S220，该接入网设备根据映射规则，确定该第一QFI对应的第二QFI；S230，该接入网设备向终端设备发送与该第一数据包对应的第二数据包，该第二数据包的包头包括该第二QFI，以便于该终端设备根据该第二QFI确定对应的该第一QFI。
在S210中，接入网设备接收核心网设备发送的第一数据包，该第一数据包包括第一QFI，例如，该接入网设备可以通过N3接口接收核心网设备发送的该第一数据。其中，该第一数据包中的第一QFI可以为动态的显性指示，例如，该第一数据包的包头中包括该第一QFI，通过该第一QFI指示目标QoS flow，该第一QFI可以占用7bit，或者也可以为小于7bit；或者，该第一数据包中的第一QFI可以为隐式指示，例如，该第一数据包包括5QI的值，令该5QI的值等于第一QFI的值，由于目前5QI的值需要7bit表示，则对应的该第一QFI为7bit。
在S220中，接入网设备根据映射规则，确定该第一QFI对应的第二QFI，其中，通过映射，可以改变原QFI占用的比特数，即该第一QFI占用的比特数可以大于第二QFI的比特数。具体地，若接入网设备接收到的该第一QFI占用的比特数小于或者等于接入网设备与终端设备之间支持的QFI占用的大小，则该接入网设可以不进行映射，而将包括该第一QFI的第一数据包转发至终端设备，例如，该第一QFI为6bit时，接入网设备与终端设备之间支持6bit的QFI的传输，则该接入网设备可以将包括该6bit的第一QFI的第一数据包转发至终端设备。
但是，若该第一QFI占用的比特数大于接入网设备与终端设备之间支持的QFI占用的大小，则该接入网设备可以根据映射规则，将该第一QFI映射为第二QFI，并在S230中，接入网设备向终端设备发送与第一数据包对应的第二数据包，该第二数据包的包头包括该第二QFI，以便于终端设备根据映射规则，确定该第二QFI对应的第一QFI。
例如，该第一QFI为7bit，而接入网设备与终端设备之间仅支持6bit的QFI的传输，因此，该接入网设备可以将该7bit的第一QFI根据映射规则映射为6bit的第二QFI，并向终端设备发送包括该第二QFI的第二数据包。
可选地，该方法200中的映射规则与方法100中的映射规则类似，该方法200中的映射规则可以包括：在该第一QFI为超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系；该映射规则还可以包括：在该第一QFI为未超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系，在此不再赘述。
应理解，接入网设备根据映射规则确定第一QFI对应的第二QFI，对应的，该方法200还可以包括：该接入网设备向终端设备发送RRC信令，该RRC信令用于指示映射规则，以便于终端设备根据该映射规则，确定第二QFI对应的第一QFI。
因此，本申请实施例的用于下行数据传输的方法，接入网设备接收核心网设备发送的第一数据包，该第一数据包包括第一QFI，根据映射规则，确定该第一QFI对应的第二QFI，再向终端设备发送包括该第二QFI的第二数据包，使得在接入网设备接收到的第一数据包中的第一QFI占用比特数较大时，通过映射为占用较少比特数的第二QFI，从而实现传输至终端设备，并使得终端设备根据映射规则，确定第二QFI对应的第一QFI。
上文中结合图1和图2，分别从核心网设备和接入网设备的角度详细描述了根据本申请实施例的用于下行数据传输的方法，下面将结合图3，从终端设备的角度描述根据本申请实施例的用于下行数据传输的方法。
图3示出了根据本申请实施例的用于下行数据传输的方法300的示意性流程图，该方法300可以由终端设备设备执行。如图3所示，该方法300包括：S310，终端设备接收接入网设备发送的数据包，该数据包的包头包括第二QFI，该第二QFI为该接入网设备或核心网设备根据该第一QFI确定的；S320，该终端设备根据映射规则，确定与该第二QFI对应的该第一QFI。
在S310中，终端设备接收接入网设备发送的数据包，该数据包的包头包括第二QFI，其中，该终端设备可以通过空口接收接入网设备发送的该数据包。可选地，该第二QFI可以为接入网设备根据第一QFI和映射规则确定的，或者也可以为核心网设备根据第一QFI和映射规则确定的。
可选地，该第二QFI可以为接入网设备根据第一QFI和映射规则确定的，即接入网设备接收核心网设备发送的数据包，该数据包包括第一QFI，由于接入网设备和核心网设备之间可以传输占用比特数较多的QFI，而接入网设备和终端设备之间不支持，所以接入网设备根据该第一QFI和映射规则，确定对应的第二QFI，该第二QFI的比特数小于第一QFI的比特数，从而实现向终端设备发送包括该第二QFI的数据包。
可选地，该第二QFI也可以为核心网设备根据第一QFI和映射规则确定的，由于接入网设备和核 心网设备之间可以传输占用比特数较多的QFI，而接入网设备和终端设备之间不支持，所以核心网设备根据该第一QFI和映射规则，确定对应的第二QFI，该第二QFI的比特数小于第一QFI的比特数，并向接入网设备发送包括该第二QFI的数据包，使得接入网设备能够直接再向终端设备转发该包括第二QFI的数据包。
在S320中，终端设备根据映射规则，确定该第二QFI对应的第一QFI。具体地，若在S310接收的数据包中的第二QFI为接入网设备根据映射规则确定的，该终端设备还可以接收接入网设备发送的RRC信令，该RRC信令用于指示该映射规则，或者，该映射规则也可以为预先配置的，例如由SDAP层协议预先设置的。若在S310接收的数据包中的第二QFI为核心网设备根据映射规则确定的，该终端设备还可以接收核心网设备发送的NAS信令，该NAS信令用于指示该映射规则，或者，该映射规则也可以为预先配置的。
应理解，由于终端设备与接入网设备之间传输的QFI占用比特数的限制，对于占用比特数较大的第一QFI，接入网设备或核心网设备可以根据映射规则，确定与第一QFI对应的第二QFI，该第二QFI占用的比特数小于第一QFI占用的比特数。则对应的，终端设备接收该第二QFI，根据映射规则，确定对应的第一QFI。
可选地，该方法300中的映射规则与方法100和200中的映射规则相同，核心网设备或者接入网设备通过该映射规则将第一QFI映射为第二QFI，而方法300中，终端设备根据该相同的映射规则，将第二QFI映射为第一QFI。具体地，该方法300中的映射规则可以包括：在该第一QFI为超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系；该映射规则还可以包括：在该第一QFI为未超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系，在此不再赘述。
因此，本申请实施例的用于下行数据传输的方法，终端设备接收包括第二QFI的数据包，该第二QFI为接入网设备或者核心网设备根据映射规则和第一QFI确定的，则终端设备根据映射规则，确定第二QFI对应的第一QFI，使得核心网设备、接入网设备以及终端设备之间顺利传输QFI，解决了通过N3接口传输QFI和通过空口传输QFI时QFI占用的比特数不匹配的问题。
下面将结合两个具体实施例，描述根据本申请实施例的用于下行数据传输的方法。
图4示出了根据本申请实施例的用于下行数据传输的方法400的示意图。如图4所示，该方法400包括以下步骤。
在S410中，核心网设备根据映射规则，确定第一QFI对应的第二QFI。
应理解，该核心网设备可以通过该映射规则，改变QFI占用的比特数的大小，即该第一QFI占用的比特数大于第二QFI占用的比特数。例如，该第一QFI占用7bit，该第二QFI占用6bit。
在S420中，核心网设备向接入网设备发送数据包，该数据包的包头包括在S410中确定的第二QFI。
应理解，该核心网设备可以通过N3接口发送该数据包。
在S430中，接入网设备将该包括第二QFI的数据包转发至终端设备。
应理解，核心网设备将占用较大比特数的第一QFI，映射为较小的第二QFI，以便于接入网设备与终端设备之间支持该第二QFI的传输。
在S440中，终端设备接收该数据包，根据映射规则，确定该数据包的包头中的第二QFI对应的第一QFI，以便于确定对应的QoS flow和/或该QoS flow的属性，例如，该第一QFI可以表示5QI的值。
应理解，该方法400中S410与S440中的映射规则为相同的映射规则，具体地，根据上述方法100至300，该映射规则可以包括：在该第一QFI为超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系；该映射规则还可以包括：在该第一QFI为未超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系，在此不再赘述。
应理解，终端设备中的映射规则可以为预先设置的，或者，终端设备可以接收该核心网设备发送的NAS信令，该NAS信令包括该映射规则。
图5示出了根据本申请实施例的用于下行数据传输的方法500的示意图。如图5所示，该方法500包括以下步骤。
S510，核心网设备向接入网设备发送第一数据包，该第一数据包包括第一QFI。
应理解，该第一数据包中的第一QFI可以为动态的显性指示，例如，该第一数据包的包头中包括该第一QFI，通过该第一QFI目标QoS flow；或者，该第一数据包中的第一QFI可以为隐式指示，例如，该第一数据包包括5QI的值，令该5QI的值等于第一QFI的值。
可选的，该第一QFI占用的比特数的大于接入网设备与终端设备之间支持的传输QFI的比特数大小。例如，该第一QFI为7bit，而接入网设备与终端设备之间仅支持6bit的QFI的传输。
S520，接入网设备根据映射规则，确定该第一QFI对应的第二QFI。
应理解，该第一QFI占用的比特数的大小大于第二QFI的，也就是通过映射规则，改变原QFI占用的比特数的大小，以便于支持接入网设备与终端设备之间的QFI的传输。
S530，接入网设备向终端设备发送与第一数据包对应的第二数据包，该第二数据包包括第二QFI。
应理解，该接入网设备可以通过空口向终端设备发送该第二数据包。
S540，终端设备根据映射规则，确定第二QFI对应的第一QFI，以便于确定对应的QoS flow和/或该QoS flow的属性，例如，该第一QFI可以表示5QI的值。。
应理解，该方法500中S520与S540中的映射规则为相同的映射规则，具体地，根据上述方法100至300，该映射规则可以包括：在该第一QFI为超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系；该映射规则还可以包括：在该第一QFI为未超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系，在此不再赘述。
应理解，终端设备中的映射规则可以为预先设置的，或者，终端设备可以接收该接入网设备发送的RRC信令，该RRC信令包括该映射规则。
因此，本申请实施例的用于下行数据传输的方法，由核心网设备或者接入网设备根据映射规则将第一QFI映射为第二QFI，并向终端设备发送包括该第二QFI的数据包，以便于终端设备根据映射规则确定第二QFI对应的第一QFI，从而使得核心网设备、接入网设备以及终端设备之间顺利传输QFI，解决了通过N3接口传输QFI和通过空口传输QFI时QFI占用的比特数不匹配的问题。
上文中结合图1至图5，详细描述了根据本申请实施例的用于下行数据传输的方法，下面将结合图6至图10，描述根据本申请实施例的用于上行数据传输的方法。
图6示出了根据本申请实施例的用于上行数据传输的方法600的示意性流程图，该方法600可以由终端设备执行。如图6所示，该方法600包括：S610，终端设备根据映射规则，确定第一QFI对应的第二QFI；S620，该终端设备向接入网设备发送数据包，该数据包的包头包括该第二QFI。
应理解，在RAN侧，SDAP层根据分配结果会给每个SDAP PDU标识QFI，用来表示QoS flow到DRB的映射关系。对于下行，QFI可以由RAN(SDAP层)侧标识并在空口传输，目的是为了表示反射QoS(Reflective QoS，RQoS),如果NR-RAN或者NAS都不使用反射映射(reflective mapping)，那么可以不用在下行空口传输QFI，否则需要传输QFI。对于上行，NG-RAN可以配置UE在空口传输QFI。
具体地，在S610中，终端设备通过第一QFI标识目标QoS flow，若该第一QFI占用的比特数较大，即大于终端设备向接入网设备发送的QFI能够占用的比特数的最大值，不满足终端设备与接入网设备之间QFI的传输要求，终端设备可以通过映射规则，确定第一QFI对应的第二QFI，该第二QFI占用的比特数小于该第一QFI，以便于在S620中，终端设备能够向接入网设备发送数据包，该数据包的包头包括该第二QFI。
例如，若第一QFI占用7bit，假设终端设备与接入网设备最多支持6bit的QFI的传输，则需要将该第一QFI映射为第二QFI，该第二QFI占用比特数小于第一QFI，例如第二QFI可以占用6bit或占用小于6bit，并在S620中，终端设备能够向接入网设备发送数据包，该数据包的包头包括该第二QFI。
再例如，若第一QFI占用7bit，假设该终端设备与接入网设备最多支持7bit的QFI的传输，第一QFI满足该要求，则终端设备可以直接向接入网设备传输该7bit的第一QFI，而无需进行映射，即终端设备向接入网设备发送数据包，该数据包包括该第一QFI，对应的，接入网设备和核心网设备之间同样也支持传输7bit的QFI，则接入网设备再将包括该第一QFI的数据包转发至核心网设备，但本申请实施例并不限于此。
应理解，该方法400中的终端设备使用的映射规则可以与方法100中的映射规则类似，该方法400中的映射规则也可以包括：在该第一QFI为超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系；该映射规则还可以包括：在该第一QFI为未超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系，在此不再赘述。
具体地，终端设备可以根据该映射规则，通过SDAP层将第一QFI映射为第二QFI，对应的，终端设备向接入网设备发送包括第二QFI的数据包，例如，终端设备可以通过空口向接入网设备发送该数据包，以便于接入网设备根据映射规则，将该第二QFI映射为第一QFI，该接入网设备还可以向核心网设备发送包括该第一QFI的数据包，
其中，该接入网设备和终端设备使用的映射规则相同。具体地，终端设备的映射规则可以为预先设置的，例如，该映射规则可以为SDAP层协议规定的；或者，该终端设备还可以接受接入网设备发送的RRC信令，该RRC信令用于指示该映射规则。
可选地，终端设备还可以根据该映射规则，通过SDAP层的上层将第一QFI映射为第二QFI，例如，通过应用层将第一QFI映射为第二QFI，对应的，终端设备向接入网设备发送包括第二QFI的数据包， 以便于接入网设备向核心网设备转发该包括该第二QFI的数据包，核心网设备根据映射规则，将该第二QFI映射为第一QFI。
其中，该核心网网设备和终端设备使用的映射规则相同。具体地，终端设备的映射规则可以为预先设置的；或者，该终端设备还可以接受核心网设备发送的NAS信令，该NAS信令用于指示该映射规则。
因此，本申请实施例的用于上行数据传输的方法，终端设备根据映射规则，确定第一QFI对应的第二QFI，并向接入网设备发送包括该第二QFI的数据包，使得在第一QFI占用的比特数不满足终端设备与接入网设备之间的传输要求时，通过映射为第二QFI，实现向接入网设备发送QFI，从而使得接入网设备和核心网设备成功接收并确定正确的QFI。

在本申请实施例中，终端设备确定目标QoS flow的标识为第一QFI，该第一QFI不满足终端设备与接入网设备之间的传输要求，终端设备可以通过SDAP层，根据映射规则确定第一QFI对应的第二QFI，并向接入网设备发送包括该第二QFI的数据包，该数据包为第二数据包，该第二数据包的包头可以包括该第二QFI。对应的，接入网设备接收该包括第二QFI的第二数据包，并根据映射规则，确定该第二QFI对应的第一QFI，并向核心网设备发送包括该第一QFI的第一数据包，例如，通过N3接口向核心网设备发送该第一数据包，其中，第一QFI占用的比特数满足接入网设备和核心网设备之间的传输要求。可选地，第一QFI占用的比特数可以大于第二QFI占用的比特数。
可选地，接入网设备向核心网设备发送包括第一QFI的第一数据包，其中，该第一数据包中的第一QFI可以为动态的显性指示，例如，该第一数据包的包头中包括该第一QFI，通过该第一QFI指示目标QoS flow，该第一QFI可以占用7bit，或者也可以为小于7bit；或者，该第一数据包中的第一QFI可以为隐式指示，例如，该第一数据包包括5QI的值，令该5QI的值等于第一QFI的值，由于目前5QI的值需要7bit表示，则对应的该第一QFI为7bit。
应理解，该方法500中接入网设备使用的映射规则与方法400中的终端设备使用的映射规则对应，同样可以与方法100中的映射规则类似，该方法500中的映射规则也可以包括：在该第一QFI为超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系；该映射规则还可以包括：在该第一QFI为未超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系，在此不再赘述。
应理解，该方法600还包括：接入网设备向终端设备发送RRC信令，该RRC信令用于指示该映射规则。具体地，接入网设备与终端设备使用相同的映射规则，终端设备根据该映射规则，确定第一QFI对应的第二QFI，相反的，接入网设备根据该映射规则，确定第二QFI对应的第一QFI。
因此，本申请实施例的用于上行数据传输的方法，终端设备根据映射规则，确定第一QFI对应的第二QFI，并向接入网设备发送包括该第二QFI的第二数据包，接入网设备根据该第二数据包中的第二QFI，按照映射规则确定对应的第一QFI，并向核心网设备发送包括该第一QFI的第一数据包，使得在第一QFI占用的比特数不满足终端设备与接入网设备之间的传输要求时，通过终端设备将其映射为第二QFI，实现向接入网设备发送QFI，再由该接入网设备根据映射规则确定与第二QFI对应的第一QFI，从而使得接入网设备和核心网设备成功接收并确定正确的QFI。
上文中结合图6和图7，分别从终端设备和接入网设备的角度详细描述了根据本申请实施例的用于上行数据传输的方法，下面将结合图8，从核心网设备的角度描述根据本申请实施例的用于上行数据传输的方法。
图8示出了根据本申请实施例的用于上行数据传输的方法800的示意性流程图，该方法800可以由核心网设备执行。如图8所示，该方法800包括：S810，核心网设备接收接入网设备发送的数据包，该数据包的包头包括第二QFI，该第二QFI为该终端设备根据该第一QFI确定的；S820，该核心网设备根据映射规则，确定与该第二QFI对应的该第一QFI。
在本申请实施例中，终端设备确定目标QoS flow的标识为第一QFI，该第一QFI不满足终端设备与接入网设备之间的传输要求，终端设备可以通过SDAP层的上层，例如应用层，根据映射规则确定第一QFI对应的第二QFI，并向接入网设备发送包括该第二QFI的数据包，其中，该数据包的包头可以包括该第二QFI。对应的，接入网设备接收该包括第二QFI的数据包，并向核心网设备转发该包括第 二QFI的数据包，例如，通过N3接口向核心网设备发送该数据包，则核心网设备根据映射规则，确定该第二QFI对应的第一QFI，其中，第一QFI占用的比特数满足接入网设备和核心网设备之间的传输要求。可选地，第一QFI占用的比特数可以大于第二QFI占用的比特数。
应理解，该方法600中核心网设备使用的映射规则与方法400中的终端设备使用的映射规则对应，同样可以与方法100中的映射规则类似，该方法600中的映射规则也可以包括：在该第一QFI为超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系；该映射规则还可以包括：在该第一QFI为未超过该第二QFI的表示范围的值时，该第一QFI的值与该第二QFI的特定的值之间的映射关系，在此不再赘述。
应理解，该方法700还包括：核心网设备向终端设备发送NAS信令，该NAS信令用于指示该映射规则。具体地，核心网设备与终端设备使用相同的映射规则，终端设备根据该映射规则，确定第一QFI对应的第二QFI，相反的，核心网设备根据该映射规则，确定第二QFI对应的第一QFI。
因此，本申请实施例的用于上行数据传输的方法，终端设备根据映射规则，确定第一QFI对应的第二QFI，并向接入网设备发送包括该第二QFI的数据包，接入网设备向核心网设备转发该数据包，使得核心网设备根据该数据包中的第二QFI，按照映射规则确定对应的第一QFI，使得在第一QFI占用的比特数不满足终端设备与接入网设备之间的传输要求时，通过终端设备将其映射为第二QFI，实现向接入网设备发送QFI，再由该接入网设备转发至核心网设备，核心网设备根据映射规则确定与第二QFI对应的第一QFI，从而使得接入网设备和核心网设备成功接收并确定正确的QFI。
