Description

数据传输的控制方法和设备
本申请要求于2017年1月9日提交中国专利局、申请号为PCT/CN2017/070681、申请名称为“数据传输的控制方法和数据传输装置”的国际专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种数据传输的控制方法和设备。
背景技术
无线网络作为基础的网络架构，越来越多的业务在无线网络上承载。根据业务的特性、要求，以及无线资源的稀缺性，决定了网络的行为，而网络的行为事先由服务质量(Quality of Service，QoS)规则(rule)来定义和实现接入控制，资源保证和调度，例如，当你正在打一个电话时，某人开始下载一个文件，由于无线资源的稀缺性，下载一个文件会抢占你通信的通信资源而导致你正在通信的电话被挂断，此时，就需要保证语音通话的无线资源比下载一个文件具有更高的资源使用优先级，这样才能保证无线资源不足时，语音通话正常。当然，在无线网络中，会有不同的业务接入，需要设置不同的QoS rule以保证关键的业务得到保证。
在3GPP中所定义的EPS无线***中QoS的管理方式为：EPS***提供的各种IP业务的QoS保障可以通过一个IP业务传输其数据的一个或多个服务数据流(service data flow，SDF)来标识，一个SDF对应一个EPS承载，即一个SDF通过一个EPS承载来传输，以实现IP业务的QoS保障。其中，承载为逻辑传输通道。这样，IP业务的QoS保障就转化为EPS承载的QoS保障，或者说一个特定QoS的SDF映射到一个特定QoS的EPS承载上。其中，承载为逻辑传输通道。EPS承载是用户设备(User Equipment，UE)到PGW(PDN GateWay)之间的一种逻辑传输通道。
服务数据流和承载通过数据流模板(Traffic Flow Template，TFT)进行关联和映射，而在无线网络中与RB-ID进行关联，在核心网中与隧道端点标识符(Tunnel End Point Identity，TEID)进行关联。上行数据流和TFT的关联由UE执行，下行数据流的TFT由PGW执行。其中，每个SDF包括至少一个IP数据流过滤器(IP Flower Filter)。将不同的业务根据不同的QoS需求由TFT过滤到不同的承载上传输，实现了QoS保障。
在3GPP中规定了在与固定宽带网互通时，固网内部根据DSCP标记进行QoS控制。对于下行业务，3GPP网络设置每个IP包的DSCP值。当通过隧道将数据传输给UE时，网络会将内层IP包头的DSCP值复制到外层的IP头中，实现反转(Reflective)QoS。Reflective QoS是指固网用户UE的上行数据的Qos机制采用其下行数据的一样的QoS机制。对于上行业务，当UE支持reflective QoS时，UE根据接收到的下行数据包创建DSCP标记规则，并在发送IP包时，根据该规则设置IP包的DSCP值。
然而，在3GPP无线网络QoS机制中，只涉及IP数据包的处理，并没有涉及非IP(non-IP)数据包的处理，对于5G网络还需要明确如何支持非IP数据包的QoS保障机制。其中，IP 数据包可以简称为IP包。IP包为支持IP协议通信传输中的数据单位；非IP包为除支持IP协议通信传输中，支持其他协议通信传输的数据单位。

具体实施方式
下面通过附图和实施例，对本申请的技术方案做进一步的详细描述。
本申请提出了一种与协议无关的服务质量(Quality of Service，QoS)传输处理机制，通过获取结构化的数据包过滤器(structure packet filters，SPF)来完成数据流的分类与处理，解决了5G网络通信数据传输中对传输的非IP数据包的QoS保障。其中，不同的包过滤器对应网络的不同QoS规则(rule)控制。
网络中传输的数据包的分类包括结构化的IP包和非IP包。非IP包又包括结构化的非IP包(如以太帧)和非结构化的非IP包，例如用于物联网(Internet of Things，IOT)场景下的裸包或者私有协议包。这里的裸包是指没有协议头的数据包，从包头第一位开始就是数据信息。本申请实施例配置的包过滤器适用于结构化的IP包和结构化的非IP包。
需要说明的是，本申请实施例中的“结构化”是指数据的存储方式遵循一定的协议格式，存储按照比特(binary digit，bit)或者字节存储。例如IEEE802.3以太帧头格式和每个字段的指示信息如数据包格式1所示。
数据包格式1
前导码 帧开始符 目标地址 源地址 长度/类型 数据和填充注 帧校验序列
7 1 6 6 2 46-1500 4
在IEEE802.3以太帧头格式中，前导码(Preamble)用于同步，占用的字段长度为7个字节；帧开始符(Start Frame Division，SDF)用于表明下一个字节为目的媒体访问控制(Media Access Control，MAC)地址，占用的字段长度为1个字节；目的MAC地址用于执明帧的接受者，占用的字段长度为6个字节；源MAC地址用于执明帧的发送者，占用 的字段长度为6个字节；长度(Length)/类型(Type)用于表示帧中数据字段的长度或者帧中数据的协议类型，长度或者类型占用的字段长度为2个字节；数据和填充(Data and Pad)注为高层的数据，通常为3层协议数据单元，例如TCP/IP中的IP数据包，占用的字段长度为46-1500个字节；帧校验序列(frame check sequence，FCS)用于对接收网卡提供判断是否传输错误的一种方法，若发现错误，则丢弃此帧，占用的字段长度为4个字节。
又例如802.1Q数据包头格式，如表数据包格式2所示。
数据包格式2
Figure PCTCN2017097399-appb-000001
与IEEE802.3的区别在于，802.1Q包含了VLAN包(VLAN Tag)，表明其组播的VLAN。其中，802.1Q VLAN Tag占用字段的长度为4bit。802.1Q VLAN包中包括包协议标识(Tag Protocol ID)0x8100，用户优先级(User Priority)，规范格式指示(Canonical Format Indicator)和VLAN标识(VLAN ID)。
又例如IP数据包包头的格式，如数据包格式3所示。
数据包格式3
Figure PCTCN2017097399-appb-000002
数据包格式3中的版本号(Version)占用的字段长度为4比特，用于表示采用的IP协议的版本号，一般的值为0100(IPv4)或者0110(IPv6)。
IP包头长度(Header Length)占用的字段长度为4比特，用于描述IP包头的长度，因为在IP包头中有变长的可选部分。该部分占4个bit位，单位为32bit(4个字节)，即本区域值＝IP头部长度(单位为bit)/(8*4)，因此，一个IP包头的长度最长为“1111”，即15*4＝60个字节。IP包头最小长度为20字节。
服务类型(Type of Service)占用的字段长度为8比特。8位按位被如下定义PPPDTRC0。
PPP：定义包的优先级，取值越大数据越重要；
000普通(Routine)；
001优先的(Priority)；
010立即的发送(Immediate)；
011闪电式的(Flash)；
100比闪电还闪电式的(Flash Override)；
101CRI/TIC/ECP；
110网间控制(Internetwork Control)；
111网络控制(Network Control)。
需要说明的是，DTRC0中的“D”表示时延(Delay)；“T”表示吞吐量(throughput)；“R”表示可靠性(reliability)；“M”表示传输成本；最后一位的“0”保留，恒定为0。
IP包总长(Total Length)占用字段长度为16比特。以字节为单位计算的IP包的长度(包括头部和数据)，所以IP包最大长度为65535字节。
标识符(Identifier)占用的字段长度为16比特。该字段和IP标记(Flags)和片偏移(Fragment Offest)字段联合使用，对较大的上层数据包进行分段(fragment)操作。路由器将一个包拆分后，所有拆分开的小包被标记相同的值，以便目的端设备能够区分哪个包属于被拆分开的包的一部分。
标记(IP Flags)占用的字段长度为3比特。该字段第一位(X)不使用。第二位是DF(Don't Fragment)位，DF位设为1时表明路由器不能对该上层数据包分段。如果一个上层数据包无法在不分段的情况下进行转发，则路由器会丢弃该上层数据包并返回一个错误信息。第三位是MF(More Fragments)位，当路由器对一个上层数据包分段，则路由器会在除了最后一个分段的IP包的包头中将MF位设为1。其中，第二位“DF”可以简写为“D”；第三位“MF”可以简写为“M”。
片偏移(Fragment Offset)占用的字段长度为13比特。表示该IP包在该组分片包中的位置，接收端靠该片偏移来组装还原IP包。
生存时间(Time To Live，TTL)占用的字段长度为8比特。当IP包进行传送时，先会对该字段赋予某个特定的值。当IP包经过每一个沿途的路由器的时候，每个沿途的路由器会将IP包的TTL值减少1。如果TTL减少为0，就丢弃该IP包。这个字段可以防止由于路由环路而导致IP包在网络中不停被转发。
协议(Protocol)占用的字段长度为8比特。标识了上层所使用的协议。比较常用的协议包括：互联网控制报文协议(Internet Control Message Protocol，ICMP)、互联网组管理协议((Internet Group Manage Protocol，IGMP)、传输控制协议(Transmission Control Protocol，TCP)、用户数据报协议(User Datagram Protocol，UDP)、内部网关路由协议((Interior Gateway Routing Protocol，IGRP)，开放最短路径优先(Open Shortest Path First，OSPF)属于一个内部网关协议((Interior Gateway Protocol，IGP)，等等。
头部校验(Header Checksum)占用的字段长度为16位。用来做IP头部的正确性检测，但不包含数据部分。因为每个路由器要改变TTL的值，所以路由器会为每个通过的数据包重新计算这个值。
起源和目标地址(Source and Destination Addresses)：这两个字段均占用32比特。 标识了这个IP包的起源和目标地址。要注意除非使用网络地址转换(Network Address Translation，NAT)，否则整个传输的过程中，这两个地址不会改变。
可选项(IP Options)是一个可变长的字段。
根据数据包格式1的以太帧头格式、数据包格式2的802.1Q数据包头格式，以及数据包格式3的IP数据包包头格式的举例可知，结构化的数据包，其头域字段在数据包包头的存储为位置是固定的，因此提出本申请的技术方案，通过配置结构化的包过滤器来完成数据流的分类与处理，以实现5G网络通信数据传输中对传输的非IP数据包的QoS保障。
下面结合附图对本申请的技术方案进行详细的描述。
图1为本申请实施例提供的一种数据传输控制***的架构图。如图1所示，该***可以包括：应用功能(applicationfunction，AF)设备、策略功能(policy function，PCF)设备、控制面(controlplane function，CPF)节点、数据网络(data network，DN)、用户面(user plan function，UPF)节点、接入网(accessing network，AN)(或radio accessing network，RAN)设备和终端(user equipment，UE)。该***可以包括UDM。
其中，该CPF可以包括接入与移动管理功能实体(access and mobility management function，AMF)和会话管理功能实体(session management function，SMF)，AMF通过隧道NG11与SMF通信。AF可以通过NG5与PCF相连；PCF可以通过NG7与CPF通信；CPF中的SMF可以通过NG4与UPF通信，还可以通过NG10与UDM通信；CPF中的AMF可以通过NG1与UE通信，还可以通过NG8与UDM通信；CPF中的AMF可以通过NG2与AN通信；AN与UE通信，AN可以通过NG3与UPF；UPF可以通过NG3与DN通信。UPF和UE可以统称为数据传输装置。
图1所述的***可以应用在5G的会话建立(业务建立)或会话更新(业务更新)的场景中。PCF配置QoS规则，QoS规则中包括结构化的包过滤器，例如，将分组数据单元(Packets data unit，PDU)会话(Session)按照结构化(Structure)的PDU会话类型(type)和非结构化(Unstructure)的PDU类型进行分类。QoS规则中可以包括按照结构化PDU会话类型配置结构化的包过滤器。结构化的包过滤器可以包括至少一个结构化过滤器规则(SPT rule)，例如SPT＝(SPF rule 1和SPF rule 2)或者(SPF rule 3和SPF rule4)或者SPF rule 5，等等。
在本申请实施例中，结构化的数据包过滤器可以简称为数据包过滤器；结构化过滤器规则可以简称为包过滤器规则。每个包过滤器规则可以包括数据类别标识信息和匹配条件，匹配条件用于规定位置信息对应的待传输数据与QoS传输处理机制的匹配关系。匹配条件可以包括操作(Operation)或者运算信息，以及匹配信息(或者称为匹配值(match data))，数据类别标识信息用于对待传输数据按照服务质量进行分类。
例如，UE需要传输上行数据，需要与包过滤器匹配，例如包过滤器的SPF rule为SPF rule 1，根据运算信息“＝”对上行数据0bit位的数据进行运算，得到匹配值，若匹配值与SPF rule 1中匹配信息1相等，则UE采用SPF rule 1对应的承载传输该上行数据。
匹配信息可以为不同协议类型中，结构化数据包包头中数据类别标识信息，例如IP协议类型中的目标MAC地址信息、源MAC地址信息或协议类型中任一项等；运算信息规定了一种逻辑关系，该逻辑比较关系如表1至表5所示，可为大于、等于、 小于、大于或等于，小于或等于，和、或以及16进制转换等；若数据类别标识信息所指示的待传输数据包和待比较数据包的关系符合运算信息中规定的逻辑关系，则将该数据包分配到与该包过滤器对应的服务质量QoS传输处理机制上进行数据传输。其中，QoS传输处理机制的功能类似与4G通信***中，EPS承载，简称承载的功能。
在本发明的一个实施例中，数据包过滤器可以包括至少一个包过滤规则，每个数据包过滤器包括数据类别标识信息、运算信息，以及匹配信息。或者，每个数据包过滤规则包括数据类别标识信息和匹配信息。
其中，数据类别标识信息可以包括数据包检测头域的位置信息(field position information)(下面简称“位置信息”)或服务质量需求标识。
数据包过滤器中的服务质量需求标识用于指示业务数据包对应的服务质量信息。服务质量需求标识可以通过运营商和内容提供商合作或协议制定得出。服务质量需求标识为在业务数据包中一个或多个字段携带的与相应的服务质量对应的标识信息。也就是说，运营商根据不同的服务质量需求标识为携带不同质量服务标识的业务数据包提供不同的QoS服务。数据包过滤器根据不同的服务质量需求标识和匹配信息，将待传输数据包分配到对应的QoS传输处理机制进行发送。
以结构化的非IP数据包为例，服务质量需求标识可以在非IP数据包的包头部分中，如图2所示，非IP数据包可以包括包头的服务质量需求标识和包头的其他信息(如长度信息和版本信息)以及负荷部分。可以理解的是，非IP数据包可以通过增加新的字段携带服务质量需求标识，也可以将服务质量需求标识放在非IP数据包包头的预留字段中，本发明实施例在此不作限定。
数据包过滤器中的位置信息为业务数据包包头的一个或多个字段所在位置的信息。数据包过滤器根据不同的位置信息、运算信息，以及匹配信息。或者，根据不同的位置信息和匹配信息，将待传输数据包分配到对应的QoS传输处理机制进行发送。
数据包过滤器中的位置信息可以是根据对现有的结构化的协议进行分析，确定相应的需要用于策略匹配判断的位置信息。如IP协议中的IP五元组所在的位置信息，如以太网协议中的MAC地址的位置信息。或者是运营商自己封装的数据包所用的协议的关键头域的位置信息，如运营商把非IP包用IP协议进行封装，则位置信息就是IP协议中的IP五元组所在的位置信息。以结构化的非IP数据包为例，如图3所示，非IP数据可以包括包头部分和负荷部分。包头部分可以包括位置信息和其他信息(如长度信息和版本信息)，其中，位置信息可以是位置1的比特位信息、位置2的比特位信息至位置n的比特位信息。
在本发明的一个实施例中，数据包过滤器可以包括至少一个包过滤规则，每个数据包过滤器包括位置信息、运算信息，以及匹配信息。配置的结构化的包括过滤器如表1所示。
表1
数据包过滤器 位置信息 运算信息(＝，>，<，or，and，xor) 匹配信息
SPF rule 1 bit 0 ＝ 1
SPF rule 2 bit 4-7 and 0 0
SPF rule 3 bit 8-15 > 10
SPF rule 4 bit 23-48 ＝ 0x12，34，56
SPF rule 5 bit 0-7 Xor 0xff＝ 0x55
其中，表1中的“or”，“and”，“xor”为一种数学运算符。
“or”表示逻辑运算中的“或”。其中，“或”在计算机中用“|”表示。运算规则为：0|0＝0；0|1＝1；1|0＝1；1|1＝1；即，参加运算的两个对象只要有一个为1，其值为1。
例如：3|5，即0000 0011|0000 0101＝0000 0111因此，3|5的值得7。
在本申请实施例中，例如，若运算信息为“或”运算(0)，则表示数据包在规则中的位置信息中该位置的值与0进行“或”运算，如果结果与匹配信息中的值一致，则该规则满足。
又例如：运算信息为(“与”运算＝101010)，表示数据包在规则中的位置信息中该位置的值与匹配信息中的值相互进行“或”运算，结果等于101010即为该规则匹配。
“and”表示逻辑运算中的“与”。其中，“与”也叫做“和”，计算机中用“&”表示。运算规则为，0&0＝0；0&1＝0；1&0＝0；1&1＝1；即，两位同时为1时，结果才为1，否则，为0。例如“3&5，即0000 0011&0101＝0000 0001，因此3&5的值得1。
在本申请实施例中，例如：若运算信息为“与”运算(0)，则表示数据包在规则中的位置信息中该位置的值与0进行“与”运算，如果结果与匹配信息中的值一致，则该规则满足。
又例如：若运算信息为“与”运算＝101010，则标书数据包在规则中的位置信息中该位置的值与匹配信息中的值相互进行“与”运算，结果等于101010即为与该规则匹配。
“xor”标识逻辑运算中的“异或(exclusive OR，简称xor)”。其中，运算规则为：如果a、b两个值不相同，则异或结果为1；如果a、b两个值相同，异或结果为0。
在本申请实施例中，例如：若运算信息为(异或(0))则表示数据包在规则中的位置信息中该位置的值与0进行异或运算，如果结果与匹配信息中的值一致，则该规则满足。
又例如，若运算信息为(异或＝101010)，则表示数据包在规则中的位置信息中该位置的值与匹配信息中的值相互进行异或运算，结果等于101010即为该规则匹配。另外，表1中的“0xff”表示16进制。
此外，表1所示的SPF rule 1，指示数据传输装置根据位置信息bit 0确定所要传输的数据包的bit 0位的数据，若该bit0位上的数据，和匹配信息中的数据相等，而运算信息中规定的规则为“＝”，则在SPF rule 1对应的承载，或者称为Qos传输处理机制上传输该数据包。
若该bit0位上的数据，和匹配信息中的数据不相等，而运算信息中规定的规则为“＝”，则将该数据包与其他的包过滤器进行匹配。
例如，IEEE802.3数据包包头如数据包格式1所示，其中，前导码(preamble)、帧开始符(SDF)和帧校验序列(FCS)在网卡内部处理，在上层不会体现。针对IEEE802.3配置的数据包过滤器可以主要通过目标MAC地址，源MAC地址和协议类型进行配置，例如配置的IEEE802.3的数据包过滤器如表2所示。
表2
数据包过滤器 位置信息 运算信息(＝，>，<，或，和，16进制) 匹配信息
SPF rule 1 bit 0-5 ＝ 目标MAC地址
SPF rule 2 bit 6-11 ＝ 源MAC地址
SPF rule 3 bit 12-13 ＝ 协议类型
在本申请实施例中，IEEE802.3配置的数据包过滤器可以包括多个SPF rule。例如数据包过滤器＝SPF rule 1+SPF rule 2；或者数据包过滤器＝SPF rule 1；或者包过滤器＝SPF rule 2；或者数据包过滤器＝SPF rule 3；或者数据包过滤器＝SPF rule 1+SPF rule 2+SPF rule 3。
其中，SPF rule 1、SPF rule 2可以分别来自两个不同MAC地址的设备，例如SPF rule 1来自目标MAC地址的设备，SPF rule 2来自源MAC地址的设备；SPF rule3可以为协议类型，例如：IP/PPP。
又例如，在802.1Q场景下，如数据包格式2所示，配置的数据包过滤器可以如表3和表4所示。
表3
数据包过滤器1 位置信息 运算信息(＝，>，<，或，和，16进制) 匹配信息
SPF rule 1 bit 12-14 ＝ VLAN Tag协议
表4
数据包过滤器2 位置信息 运算信息(＝，>，<，或，和，16进制) 匹配信息
SPF rule 1 bit 0-5 ＝ 目标MAC地址
SPF rule 2 bit 6-11 ＝ 源MAC地址
SPF rule 3 bit 17-18 ＝ 协议类型
又例如，IP数据包的数据包过滤器配置，IP数据包的包头格式如数据包格式3所示，设置的数据包过滤器可以如表5所示。
表5
Figure PCTCN2017097399-appb-000003
同样，TCP数据包的数据包过滤器也可以设置为表5的形式，为简洁描述，在这里不再赘述。
在4G网络的数据包处理过程中，过滤器(filter)是通过五元组对数据进行匹配的，在本申请的技术方案中TCP/IP数据包匹配的是数据包包头(或者头域)中对应的五元组所在位置的值。
可选地，在本申请实施例中，QoS规则还可以包括数据包过滤器的匹配优先级信息，用于指示UE和UPF按照数据包过滤器的匹配优先级信息对数据进行匹配。
例如：UE需要传输上行数据时，按照数据包过滤器的匹配优先级信息确定将上行数据优先与哪个数据包过滤器进行匹配，若与优先匹配的数据包过滤器匹配成功，则UE将上行数据采用优先匹配的数据包过滤器对应的承载传输该上行数据。若该上行数据没有与优先匹配的数据包过滤器匹配成功，则将该上行数据与匹配优先级信息中优先顺序排序次级的数据包过滤器进行匹配，依次对上行数据进行匹配。
UPF传输下行数据时，将下行数据与数据包过滤器进行匹配的过程与UE将上行数据与数据包过滤器匹配的过程相同，为简洁描述，在此不再赘述。
采用本申请实施例提供的数据传输的控制方法，可以根据业务的优先级，有效保证业务的QoS。
图4为本发明实施例提供的一种数据传输的控制方法流程图。该方法可以包括：
步骤410、PCF需要获取会话信息。
会话信息可以包括数据类别标识信息和业务信息，业务信息可以是数据类别标识信息对应的匹配值、业务QoS需求、UE标识、业务标识、业务所在数据网络标识(data network name，DNN)、业务所在数据网络的接口信息(如NG6隧道信息)、会话类型等信息中的一种或多种。数据类别标识信息可以包括位置信息或服务质量需求标识。
可选地，PCF需要获取会话信息可以通过PCF接收应用功能AF发送的会话信息。或者，接收控制面节点CPF发送的会话信息，其中，会话信息可以是控制面节点CPF从终端UE或统一数据管理UDM处获取。可以理解的是，PCF还可以通过其他网络实体获取该会话信息，在此不做限定。
步骤420、PCF根据数据类别标识信息和业务信息，生成策略和计费规则(Policy and Charging Control rule，PCC rule)。
策略和计费规则可以包括结构化数据的QoS规则(rule)，QoS rule可以包括第一数据包过滤器(packet filter)，第一数据包过滤器用于数据传输装置(如UPF或UE)将待传输数据分配到满足匹配关系的QoS传输处理机制进行发送。
其中，第一数据包过滤器可以包括数据类别标识信息和匹配条件。满足匹配关系为待传输数据和匹配条件中待比较数据的关系符合运算信息中规定的逻辑关系。QoS传输处理机制为控制面节点CPF为业务分配的服务质量流标识QFI(QoS Flow Identity)所采用的处理机制。
具体的，第一数据包过滤器可以包括服务质量需求标识和匹配条件，或者，第一数据包过滤器可以包括位置信息和匹配条件。
步骤430、PCF向CPF发送包括第一数据包过滤器的策略和计费规则。
PCF将包含第一数据包过滤器的策略和计费规则通过NG7发送给CPF。
第一数据包过滤器可以包括服务质量需求标识和匹配条件，或者，第一数据包过滤器可以包括位置信息和匹配条件。
步骤440、CPF根据策略和计费规则，向UPF发送第二数据包过滤器。
当CPF检测到第一数据包过滤器中的服务质量需求标识时，CPF根据匹配条件(如丢包率)，匹配相应的QFI值，生成第二数据包过滤器。
或者，CPF根据第一数据包过滤器中的位置信息和匹配条件(如丢包率)，匹配相应的QFI值，生成第二数据包过滤器。第二数据包过滤器用于UPF将待传输数据过滤后使用匹配关系的QoS传输处理机制进行发送。
CPF将第二数据包过滤器通过NG4发送给UPF。
第二数据包过滤器可以包括服务质量需求标识和匹配条件，或者，第一数据包过滤器可以包括位置信息和匹配条件。
步骤450、CPF根据策略和计费规则，向UE发送位置信息。
CPF根据策略和计费规则向UE发送服务质量规则(Qos rule)，服务质量规则可以包括第三数据包过滤器，第三数据包过滤器包括数据类别标识信息和匹配条件。
具体的，当CPF检测到第一数据包过滤器中的服务质量需求标识时，CPF根据匹配条件(如丢包率)，匹配相应的QFI值，生成第三数据包过滤器。
或者，CPF根据第一数据包过滤器中的位置信息和匹配条件(如丢包率)，匹配相应的QFI值，生成第三数据包过滤器。第二数据包过滤器用于UPF将待传输数据过滤后使用匹配关系的QoS传输处理机制进行发送。
当数据类别标识信息包括位置信息时，UE根据Qos rule中的第三数据包过滤器对上行数据进行匹配，或者说过滤，通过第三数据包过滤器中的位置信息、运算信息和匹配信息对上行数据进行匹配，例如优先匹配的第三数据包过滤器为IEEE802.3的数据包过滤器，第三数据包过滤器包括一个SPF rule2，SPF rule2的位置信息为“bit 6-11”； 运算信息为“＝”；匹配信息为“源MAC地址”，那么，UE判断上行数据中的bit 6-11位的数据和源MAC地址”数据满足“＝”的关系，则匹配成功。
又例如，优先匹配的第三数据包过滤器为802.1Q的数据包过滤器1，数据包过滤器1包括SPF rule 1，SPF rule1的位置信息为“bit 12-14”；运算信息为“＝”；匹配信息为“VLAN Tag协议”，那么，UE判断上行数据中的bit 12-14位的数据和“VLAN Tag协议”的数据满足“＝”的关系，则匹配成功。
又例如，优先匹配的第三数据包过滤器为IP数据包的数据包过滤器，第三数据包过滤器包括一个SPF rule1，SPF rule1的位置信息为“bit 12-15”；运算信息为“＝”；匹配信息为“源地址”，那么，UE判断上行数据中的bit 12-15位的数据进行和“源地址”数据满足“＝”的关系则匹配成功。
需要说明的是，在本申请实施例中，UE将上行数据与第三数据包过滤器进行匹配时，不需要确定是哪种协议的数据包过滤器，以上的优先匹配的是IEEE802.3的数据包过滤器，802.1Q的数据包过滤器1，以及IP数据包的包过滤器仅仅是为了通过具体的例子说明本申请的技术方案。
若匹配不成功，则将该上行数据与该过滤包中的其他SPF rule进行匹配，若该上行数据与该包过滤器中任一SPF rule均为匹配成功，则将该上行数据与次级匹配的包过滤器进行匹配，直到匹配成功，UE采用匹配成功的SPF rule对应的承载传输该上行数据。
若UE将上行数据与所有的包过滤器进行匹配后，依然没有匹配成功的包过滤器，则UE采用默认(default)的承载传输该上行数据。
或者，
为简化节省网络侧(如CPF)向UE下发Qos rule引起的信令开销，5G网络引入了固网的反转(Reflective)QoS机制。
CPF根据策略和计费规则向UE发送数据类别标识信息和反转规则。反转规则用于在反转QoS(reflective QoS)机制中UE根据数据类别标识信息和下行数据包推导生成推导QoS rules(Derived QoS rules)，推导QoS rules可以包括第三数据包过滤器。第三数据包过滤器用于UE将待传输数据分配到满足匹配关系的QoS传输处理机制进行发送。
若CPF通过信令发给UE的QoS rules称为显示(explicit)QoS rule，则UE根据Reflective QoS机制自动生成的QoS rules称为隐式(derived)QoS rule(或implicit QoS rule)。
以数据类别标识信息包括位置信息为例，对于IP数据包来说，UE知道数据包IP五元组的位置信息，因此可以直接通过IP五元组(目标地址、源地址、目标端口、源端口和协议类型)进行反转，生成Derived QoS rule中的第三数据包过滤器。对于结构化非IP包来说，协议中数据包的信息对于UE来说是未知的，但是可以通过预先配置或者通过AF经网络下发位置信息，获取生成Derived QoS rule中的第三数据包过滤器。
在本申请实施例中，UE传输的待传输数据可以称为上行数据。上行数据为UE向网络侧发送的数据，例如UE向AN发送的数据。UPF传输的待传输数据可以称为下行数据。下行数据为网络侧向UE发送的数据，例如UPF向UE发送的数据。
在一个例子中，若UPF接收的下行QoS规则为第二数据包过滤器对应的QoS等级为QFI 1(DL packet filter->QFI 1)。UPF接收到DN发送的下行数据包的五元组为：源IP地址、目的IP地址、源端口号、目的端口号和协议类型。其中，源IP地址(Source IP address)为X；目的IP地址(Destination IP address)为Y；源端口号(Source port number)为A；目的端口号(Destination port number)为B；协议类型(Protocol type)为C。若该下行数据包与第二数据包过滤器匹配，UPF将此下行数据包通过QFI 1传输给UE。
UE收到UPF下发的下行数据包和CPF下发的反转规则和数据类别标识信息，在Reflective QoS机制下，UE按照反转规则和数据类别标识信息中的位置信息对下行数据包对应的位置进行反转，生成第三数据包过滤器。
第三数据包过滤器为：源IP地址(Source IP address)为Y；目的IP地址(Destination IP address)为X；源端口号(Source port number)为B；目的端口号(Destination port number)为A；协议类型(Protocol type)为C。生成的第三数据包过滤器对应的QoS等级仍为QFI1(UL packet filter->QFI 1)。若上行数据包与第三数据包过滤器匹配，则UE将此上行数据包通过QFI 1传输给UPF。
可见，对于IP数据包来说，Reflective QoS机制是将源IP地址与目的IP地址的位置对换，将源端口号与目的端口号的位置对换。
需要说明的是，CPF根据会话信息中业务信息的不同，如业务信息可以包括业务1、业务2和业务3，CPF可以向UE发送对业务1的服务质量规则，该服务质量规则包括业务1数据包的数据类别标识信息、对业务2数据包的数据类别标识信息和反转规则，以及对业务3数据包的数据类别标识信息和反转规则，UE根据业务1的服务质量规则数据包生成业务1的第三数据包过滤器；UE根据业务2的数据类别标识信息和反转规则生成业务2的第三数据包过滤器；UE根据业务3的数据类别标识信息和反转规则生成业务3的第三数据包过滤器。也就是说，UE可以同时对不同的业务信息生成相应的第三数据包过滤器。
步骤460、UPF根据第二数据包过滤器，将待传输数据分配到满足匹配关系的QoS传输处理机制进行发送。
UPF接收到第二数据包过滤器后保存QoS规则，并根据第二数据包过滤器对DN下发或接收的数据包进行过滤处理，该过滤处理可以包括下行数据的QoS过滤匹配以及上行数据的检测。
UPF根据第二数据包过滤器的SPF rule对下行数据进行匹配，通过SPF rule中的位置信息、运算信息和匹配信息对下行数据进行匹配，例如优先匹配的第二数据包过滤器包括SP rule，SPF rule的位置信息为“bit23-48”；运算信息为“＝”；匹配信息为“16进制的12，16进制的34，16进制的56”，那么，UE判断下行数据中的bit23-48位的数据和匹配信息的数据满足“＝”的关系，则匹配成功。
其UPF将下行数据与第二数据包过滤器进行匹配的过程与UE将上行数据与包过滤器匹配的过程相同，为简洁描述，在这里不再赘述。
若匹配不成功，则将该下行数据与该过滤包中的其他SPF rule进行匹配，若该下行数据与该包过滤器中任一SPF rule均为匹配成功，则将该下行数据与次级匹配的包 过滤器进行匹配，直到匹配成功，UE采用匹配成功的SPF rule对应的承载传输该上行数据。
若UPF将下行数据与所有的包过滤器进行匹配后，依然没有匹配成功的包过滤器，则UPF采用默认(default)的承载传输该下行数据。
可选地，CPF还可以获取第二数据包过滤器的匹配优先级信息和第三数据包过滤器的匹配优先级信息，匹配优先级信息用于规定UPF对待传输数据进行过滤时，第二数据包过滤器之间的优先匹配的顺序，以及规定UE对待传输数据进行过滤时，第三数据包过滤器之间的优先匹配的顺序。
控制面节点CPF向UPF发送第二数据包过滤器的匹配优先级信息，以及向UE发送第三数据包过滤器的匹配优先级信息。
需要说明的是，在本申请的各种实施例中，步骤440和步骤450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。
本申请可以在5G的会话建立或会话更新的场景中，PCF获取数据类别标识信息，并通过CPF向数据传输装置(UPF和UE)分别发送包含数据类别标识信息的QoS rule，UE和UPF根据相应的数据包过滤器将待传输数据流匹配不同的QOS传输处理机制上实现了数据流的分流，保证了传输结构化的数据包，例如非IP数据包的QoS保障，同时该方法可以快速确定数据流，并对数据流进行匹配，提高了数据流传输的速度，且保证了传输非IP数据包的QoS保障。
在本申请提供的数据传输的控制方法，相对于4G传输数据的处理方法的不同之处在于，在本申请的技术方案中，UE和UPF不需要知道所传输数据所属的协议类型，只需要按照数据包过滤器中的位置信息，完成相应的运算，并判断操作后的值是否与匹配信息一致，若一致，则匹配成功，UE或UPF可以采用所匹配的数据包过滤器对应的承载传输数据，实现了所要传输数据的数据流的分流，实现了所传输结构化数据的QoS保障。
下面以数据类别标识信息包括位置信息为例进行详细说明。
图5为本发明实施例提供的一种在会话建立场景中数据传输的控制方法流程图。如图5所示，该方法可以包括：
步骤500、PCF接收AF发送的会话信息。
该会话信息可以包括结构化的PDU信息，该结构化的PDU信息可以包括位置信息
业务信息，该业务信息可以包括位置信息对应的匹配值、业务QoS需求、UE标识、业务标识、业务所在数据网络标识等中的一种或多种信息。
PCF根据位置信息和业务信息，生成默认(default)的QoS ruler，该QoS ruler可以包括第一数据包过滤器，第一数据包过滤器包括位置信息和匹配条件，以用于UPF或UE将待传输数据分配到匹配条件满足的匹配关系的QoS传输处理机制进行发送。
步骤501、UE向AMF发送PDU会话建立请求(PDU session establishment request) 消息，以指示建立PDU会话。
该PDU会话建立请求消息可以包括结构化的PDU类型(如结构化的IP数据包和结构化的非IP数据包)、会话标识(Session ID)和数据网络标识(Data Network Name，DNN)等信息。
步骤502、AMF向SMF发送会话管理请求(session management request，SM request)消息。
该会话管理请求消息可以包括PDU会话的建立请求的指示信息、Session ID、DNN等信息。
在进行该步骤之前，AMF需要进行SMF的选择过程，以从多个SMF中选择可以进行PDU会话的目标SMF，并保存Session ID和SMF ID或SMF ID地址的对应关系。
步骤503、SMF向统一数据管理模块(UDM)发送签约数据请求(subscription data request)消息，该签约数据请求可以包括DNN、Session ID、SMF ID或SMF地址等信息。
步骤504、UDM向SMF发送签约数据应答(subscription data response)消息，以获取UE的签约数据，实现UE的PDU会话身份验证/授权(PDU Session authentication/authorization)。
步骤505、SMF向PCF发送PDU-CAN会话建立请求(PDU-CAN session establishment request)消息。
在执行该步骤之前，SMF根据DNN、Session ID、SMF ID或SMF地址等信息，确定目标PCF。
步骤506、PCF向SMF发送PDU-CAN会话建立响应(PDU-CAN session establishment response)消息。
该PDU-CAN session establishment response消息可以包括默认(default)的QoS ruler，其中，该QoS ruler可以包括第一数据包过滤器
可见，通过步骤304和305，SMF获取PCF中的第一数据包过滤器。
步骤507、SMF根据DNN、Session ID、SMF ID或SMF地址等信息，确定目标UPF。SMF为该PDU session分配IP地址，保存Session ID和IP地址的对应关系，SMF为UPF分配隧道ID和地址。
步骤508、SMF向PCF发送PDU-CAN会话更新请求(PDU-CAN session modificationrequest)消息或PDU-CAN session establishment request消息。
步骤509、PCF向SMF发送PDU-CAN会话更新响应(PDU-CAN session modification response)消息或PDU-CAN session establishment response消息。
该PDU-CAN session modification response消息可以包括策略和计费规则，该策略和计费规则可以包括第一数据包过滤器。
可见，若在步骤506中SMF未获取到PCF中的第一数据包过滤器，则可以通过步骤509获取PCF中的第一数据包过滤器。
进一步的，若SMF与PCF为第一次连接，则执行步骤505至步骤507；若SMF与PCF在该会话建立之前已连接，则不需要执行步骤505和步骤506，只需要执行步骤508和步骤509。
步骤510、SMF向UPF发送N4会话建立请求(N4session establishment request)消 息。
