具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本公开的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
为了解决相关数据包无法按需传输的问题，本公开实施例在接入层AS的层3(Layer 3，L3)引入了用户面(User Plane，UP)功能实体即L3UP功能实体，该L3UP功能实体具有数据交织和解交织功能，以支持面向数据包的处理。该L3UP功能实体具有针对数据包(如网际互连协议(Internet Protocol， IP)包)的传输能力，可以以数据包为单位进行映射传输，可以将其内的IP流(即承载IP包的数据流)映射到相应的AS承载上传输至层2(Layer 2，L2)中的功能实体，其中AS承载是以服务质量(Quality of Service，QoS)为特征的数据包承载。由此，L3UP功能实体作为AS的数据锚点，可以按照数据包的传输需求(比如QoS参数要求)选择合适的L2进行数据传输，从而实现L3与L2之间按数据包传输需求的灵活连接，进而实现数据包按需传输。
下面结合附图，通过具体的实施例及其应用场景对本公开实施例提供的数据传输方法、装置、通信设备及可读存储介质进行详细地说明。
请参见图1，图1是本公开实施例提供的一种数据传输方法的流程图，该方法应用于发送端，该发送端可选为终端或者网络侧设备，该网络侧设备比如为基站。如图1所示，该方法包括如下步骤：
步骤11：第一功能实体获取IP流。
本实施例中，第一功能实体为发送端的AS的层3中的用户面功能实体，即L3UP功能实体。IP流可以表示为IP flow或者IP Flow，可以理解为承载数据包如IP包的数据流。
一些实施例中，L3UP功能实体可以从非接入层(Non Access Stratum，NAS)或者核心网接收IP flow，即AS的L3UP可以直接通过IP flow与其上层进行交互。
步骤12：第一功能实体根据IP流的QoS特征，将该IP流映射到相应的AS承载上传输至第二功能实体。
本实施例中，第二功能实体为发送端的AS的层2中的功能实体。AS的L3UP功能实体获取IP流后，可以经过L3UP的交织处理和QoS控制处理后，按照QoS要求，选择合适的AS承载(AS Bearer)发送给L2中功能实体。
AS承载为L3UP功能实体与L2中功能实体连接的承载，表示以QoS为特征的数据包承载。这样借助AS承载实现L3与L2间的数据传输时，可以基于数据包的QoS需求进行分类，而非基于数据包的业务进行分类，从而可以将QoS需求相同的一类数据包(比如可以属于不同的业务)承载至相同的AS承载进行传输，进而实现数据包按需传输。
本公开实施例的数据传输方法，第一功能实体获取IP流之后，可以根据该IP流的QoS特征将其映射到相应的AS承载上传输至第二功能实体，第一功能实体为发送端的AS的层3中的用户面功能实体，第二功能实体为AS的层2中的功能实体，AS承载是以QoS为特征的数据包承载。由此，L3UP功能实体可以按照数据包的传输需求选择合适的L2进行数据传输，从而实现L3与L2之间按数据包传输需求的灵活连接，进而实现数据包按需传输，降低了数据包开销。
本公开实施例中，第一功能实体即L3UP功能实体对IP流的处理方式可以包括以下两种：1)以IP流为单位，将整个IP流映射到L2的一个或者多个AS承载上，此情况下，同一IP流可以同时映射到不同的AS承载上；2)以IP流中的每个IP包(IP Packet)为单位，根据IP包的QoS特征，将IP流中的IP包映射到L2的一个或者多个AS承载上，此情况下，IP流中的IP包可以同时映射到不同或相同的AS承载上。
可选的，上述根据IP流的QoS特征，将该IP流映射到相应的AS承载上传输至第二功能实体可以包括：第一功能实体根据IP流中的IP包的QoS特征，将该IP流中的IP包映射到相应的AS承载上传输至第二功能实体。这样可以实现以单个IP包为单位的承载映射，从而更细粒度的满足数据包按需传输。
一些实施例中，每个IP flow到L2的连接按照每个数据包(如IP包)或者IP flow的QoS特征，同时映射到一个或者多个AS承载上。
一些实施例中，一个AS承载上承载的IP flow可以属于同一个协议数据单元(Protocol data unit，PDU)会话(Session)，也可以属于不同的PDU Session。
一些实施例中，IP flow属于终端的一个PDU Session。AS Bearer可以同时承载一个PDU Session的一个或者多个IP flow上的数据包(如IP包)，也可以同时承载多个PDU Session的多个IP flow上的数据包(如IP包)。
可选的，第一功能实体与第二功能实体之间的对应关系为一对一或者一对多。比如，若发送端为终端，L3UP功能实体对应的L2功能实体在同一个终端体内。又比如，若发送端为基站，L3UP功能实体对应的L2功能实体可以在同一台基站内，也可以在不同的基站内，实现网络侧L3UP经过多连接 与终端连接。
比如，参见图2所示，L3UP功能实体可以对接收的IP flows进行处理，可以以IP flow为单位进行处理，也可以以IP Packet为单位进行处理。L3UP功能实体针对IP flows，可以按照QoS要求，选择合适的AS Bearer发送给L2中功能实体。一个IP flow可以同时映射到一个或者多个AS Bearer上。如图2所示，L3UP和L2的连接方式是多样化的，有一对一的连接(如图2中“0”所示)，也有一对多的连接(如图2中“1”、“2”和“3”所示)。在网络侧，一个终端的L3UP和L2的连接，可以在同一台基站内，也可以在不同的基站内。如图2所示，图2中的小区(如小区1(cell 1)，小区k(cell k)，小区n(cell n))表示能够进行无线空口覆盖的传输通道，包括L2协议栈、物理层信道及相应的功能等。当终端移动而导致小区变化时，需要进行链路切换。
本公开实施例中，L2可以为传统的L2协议栈，包括服务数据适配协议(Service Data Adaptation Protocol，SDAP)、分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)、无线链路控制(Radio Link Control，RLC)和媒体接入控制(Medium Access Control，MAC)等协议子层，也可以只包括MAC协议子层(可简称为：MAC层)。
可选的，上述的第二功能实体可以为L2中的MAC层实体。
一些实施例中，当L2只包括MAC层时，L3UP直接连接到MAC层。
一些实施例中，当L2包括除MAC层以外的协议子层时，L3UP可以连接SDAP层，可以在SDAP层、PDCP层、RLC层等协议子层分别定义透传模式(Transparent Mode，TM)，即数据包经过SDAP/PDCP/RLC时，各协议子层对该数据包不进行任何处理，直接发送给其低层(Lower Layer)或者其上层(Upper Layer)，逻辑上也是相当于L3UP与MAC层直接连接。
可选的，上述根据IP流的QoS特征，将该IP流映射到相应的AS承载上传输至第二功能实体可以包括：第一功能实体根据IP流的QoS特征，将该IP流映射到相应的AS承载上传输至第三功能实体，由第三功能实体将该IP流透传至MAC层实体；其中，第三功能实体为层2中除MAC层实体之外的功能实体中的一者，比如SDAP层实体。
进一步的，MAC层实体接收到AS承载上的MAC服务数据单元(Service Data Unit，SDU)后，可以先根据AS承载的QoS参数，组建相应的MAC协议数据单元(Protocol Data Unit，PDU)；该MAC PDU中包括AS承载的标识，以由接收端根据该标识确定对应的AS承载；然后，将MAC PDU发送至接收端的MAC层实体，以实现数据包在空口的低时延高确定性按需传输。
请参见图3，图3是本公开实施例提供的一种数据传输方法的流程图，该方法应用于接收端，该接收端可选为终端或者网络侧设备，该网络侧设备比如为基站。比如，发送端为终端时，接收端为基站；或者，发送端为基站时，接收端为终端。如图3所示，该方法包括如下步骤：
步骤31：第四功能实体获取数据包。
本实施例中，第四功能实体为接收端的AS的层2中的功能实体。
步骤32：第四功能实体通过与数据包对应的AS承载，将数据包传输至第五功能实体。
本实施例中，第五功能实体为接收端的AS的层3中的用户面功能实体，即L3UP功能实体。AS承载是以QoS为特征的数据包承载。AS的L3UP功能实体从L2经过AS Bearer接收数据包后，可以经过解交织确定该数据包对应的IP flow，然后对数据包在IP f low上进行排序后，按序递交给上层。
本公开实施例的数据传输方法，第四功能实体获取数据包之后，可以通过与数据包对应的AS承载，将数据包传输至第五功能实体，第四功能实体为接收端的AS的层2中的功能实体，第五功能实体为接收端的AS的层3中的用户面功能实体，AS承载是以QoS为特征的数据包承载。由此，L3UP功能实体可以按照数据包的传输需求从L2接收数据，从而实现L3与L2之间按数据包传输需求的灵活连接，进而实现数据包按需传输，降低了数据包开销。
可选的，AS的L3UP功能实体接收到数据包后，可以解析数据包，获得数据包中每个IP包对应的IP流；然后，按照每个IP包在IP流上的顺序，将每个IP包映射至对应的IP流上传输至上层。
可选的，上述的第四功能实体可以为MAC层实体。此情况下，该MAC 层实体可以从发送端的MAC层实体接收MAC PDU；其中，该MAC PDU中包括AS承载的标识；然后，解析该MAC PDU，获得MAC SDU以及对应的AS承载，并通过与MAC SDU对应的AS承载，将MAC SDU传输至L3UP功能实体。这样，借助端到端的L3UP和MAC层的数据传输，可以实现数据包在空口的低时延高确定性按需传输。
下面结合图4对本公开实例中L3UP与MAC层的端到端传输进行说明。
本公开实例中，发送端可以为终端或者基站NB，相应的，接收端为基站NB或者终端。
针对发送端，如图4所示，IP flow可以从NAS或者核心网将相应IP包直接发送到AS或者基站，即AS的L3UP直接通过IP flow与其上层进行交互。首先，发送端的L3UP功能实体可以通过交织功能，将IP flow上的IP包映射到不同的AS Bearer上发送给MAC层实体；其次，发送端的MAC层实体接收到AS Bearer上的MAC SDU后，可以根据该AS Bearer的QoS保障指标，确定针对该MAC SDU的调度策略，包括资源分配方式、组建MAC PDU的方式(比如，是否分割成多个分段发送、是否为高低优先级的无线承载RB数据包组建一个MAC PDU等)、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)模式或者HARQ进程模式以及HARQ进程数目、物理量信道诸如码率、编码、调制方案等，并组建MAC PDU；其中，组建的MAC PDU中携带AS Bearer ID；然后，发送端的MAC层实体通过Uu口将组建的MAC PDU发送给接收端的MAC层实体。
针对接收端，如图4所示，首先，接收端的MAC层实体接收到MAC PDU后，可以解析该MAC PDU，得到MAC SDU及其对应的AS Bearer，并将解析后的MAC SDU通过其对应的AS Bearer递交给L3UP功能实体；然后，接收端的L3UP功能实体通过不同的AS Bearer接收到数据包后，解析L3UP PDU，得到每个IP包对应的IP flow，并对IP包在每个IP Flow上进行排序，按序递交给上层。需要说明的是，图4中，UE为User Equipment，即用户设备，NB为Node B，可以理解是基站。
需要说明的是，本公开实施例提供的数据传输方法，执行主体可以为数据传输装置，或者该数据传输装置中的用于执行数据传输方法的控制模块。 本公开实施例中以数据传输装置执行数据传输方法为例，说明本公开实施例提供的数据传输装置。
