终端设备向网络设备发送数据时,由于上行(uplink,UL)包延迟预算(packet delay budget,PDB)通常比产生数据的周期更长,终端设备的PDCP实体可以将先后接收到的数据保存在缓存中。如果终端设备配置了分裂RB,当数据量较大时,PDCP实体可以向主RLC实体或副RLC实体递交数据,当数据量较小时,PDCP实体可以向主RLC实体递交数据。When a terminal device sends data to a network device, the PDCP entity of the terminal device can save the data received successively in a cache because the uplink (UL) packet delay budget (PDB) is usually longer than the period of generating data. If the terminal device is configured with split RB, when the data volume is large, the PDCP entity can deliver the data to the primary RLC entity or the secondary RLC entity, and when the data volume is small, the PDCP entity can deliver the data to the primary RLC entity.
但是,根据数据量大小向主RLC实体或副RLC实体递交数据时,可能会导致某些数据超过自身的PDB需求,降低数据传输可靠性。所以,终端设备的PDCP实体如何向RLC实体递交数据,以满足数据的PDB需求,降低数据传输时延,提高数据传输可靠性成为亟待解决的技术问题。However, when delivering data to the primary RLC entity or the secondary RLC entity according to the data volume, some data may exceed its own PDB requirements, reducing data transmission reliability. Therefore, how the PDCP entity of the terminal device delivers data to the RLC entity to meet the PDB requirements of the data, reduce data transmission delay, and improve data transmission reliability has become a technical problem that needs to be solved urgently.

在描述本申请实施例之前,对本申请实施例涉及的技术术语进行描述。Before describing the embodiments of the present application, the technical terms involved in the embodiments of the present application are described.
无线接入网侧协议栈:可以包括控制面协议栈和用户面协议栈,网络设备和终端设备之间可以基于协议栈进行通信。Wireless access network side protocol stack: may include control plane protocol stack and user plane protocol stack, network equipment and terminal equipment can communicate based on the protocol stack.
其中,控制面协议栈架构即通信系统中的控制信令传输采用的协议簇,可以包括非接入(non-access stratum,NAS)层、无线资源控制(radio resource control,RRC)层、分组数据汇聚协议(packet data convergence protocol,PDCP)层、无线链路控制(radio link control,RLC)层、媒体接入控制(medium access control,MAC)层和物理(physical,PHY)层。Among them, the control plane protocol stack architecture, that is, the protocol cluster used for control signaling transmission in the communication system, may include non-access stratum (NAS) layer, radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, medium access control (MAC) layer and physical (PHY) layer.
其中,用户面协议栈架构即用户数据传输采用的协议簇,如图1所示,可以包括业务数据适配协议(service data adaptation protocol,SDAP)层、PDCP层、RLC层、MAC层和PHY层。Among them, the user plane protocol stack architecture, that is, the protocol cluster used for user data transmission, as shown in Figure 1, may include the service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer and PHY layer.
示例性的,以终端设备向网络设备发送数据为例,数据传输过程可以如下所述:数据首先到达终端设备的SDAP层,经过SDAP层的映射以后,传输到PDCP层,经过终端设备的PDCP层的处理以后传输到RLC层和MAC层,经过相应的处理之后,从物理层发送出去,通过空口传输给网络设备。网络设备的各个协议层按照与终端设备相反的处理顺序对接收到的数据依次进行对应的处理。For example, taking the case where a terminal device sends data to a network device, the data transmission process can be described as follows: the data first arrives at the SDAP layer of the terminal device, and after being mapped by the SDAP layer, it is transmitted to the PDCP layer, and after being processed by the PDCP layer of the terminal device, it is transmitted to the RLC layer and the MAC layer, and after being processed accordingly, it is sent out from the physical layer and transmitted to the network device through the air interface. Each protocol layer of the network device performs corresponding processing on the received data in turn in the opposite processing order of the terminal device.
在终端设备和网络设备侧可以形象地将各层对数据包的处理结合起来称为无线承载(radio bearer,RB),对于无线承载里的每个数据,都需要经过各个层的处理,每个层都有相应的功能实体或承载来执行相应的功能,比如SDAP层的SDAP实体、PDCP层的PDCP实体、RLC层的RLC实体(或者描述为RLC承载)、MAC层的MAC实体。On the terminal device and network device side, the processing of data packets by each layer can be figuratively combined into a radio bearer (RB). Each data in the radio bearer needs to be processed by each layer. Each layer has a corresponding functional entity or bearer to perform the corresponding function, such as the SDAP entity of the SDAP layer, the PDCP entity of the PDCP layer, the RLC entity of the RLC layer (or described as RLC bearer), and the MAC entity of the MAC layer.
分裂无线承载(split radio bearer,split RB):对于分裂RB,终端设备的PDCP实体可以关联一个主RLC(primary RLC)实体和一个或多个副RLC(secondary RLC)实体。Split radio bearer (split RB): For split RB, the PDCP entity of the terminal device can be associated with a primary RLC entity and one or more secondary RLC entities.
其中,当数据到达PDCP层之后,PDCP实体可以基于接收到的数据的数据量,当数据量较大时,PDCP实体可以向主RLC实体或副RLC实体递交数据,当数据量较小时,PDCP实体可以向主RLC实体递交数据。Among them, after the data reaches the PDCP layer, the PDCP entity can deliver the data to the primary RLC entity or the secondary RLC entity based on the data volume of the received data. When the data volume is large, the PDCP entity can deliver the data to the primary RLC entity or the secondary RLC entity. When the data volume is small, the PDCP entity can deliver the data to the primary RLC entity.
其中,数据可以包括协议数据单元(protocol data unit,PDU)和/或业务数据单元(service data unit,SDU)。Among them, the data may include protocol data unit (PDU) and/or service data unit (SDU).
示例性的,如图2所示,当数据到达PDCP层之后,PDCP实体可以将PDCP层的数据量和数据量
门限进行比较,如果数据量小于数据量门限,PDCP实体可以向主RLC实体递交数据;如果数据量大于或等于数据量门限,PDCP实体可以向主RLC实体或副RLC实体递交数据。For example, as shown in FIG2 , after the data reaches the PDCP layer, the PDCP entity can compare the data volume and data volume of the PDCP layer. If the data volume is less than the data volume threshold, the PDCP entity can deliver the data to the primary RLC entity; if the data volume is greater than or equal to the data volume threshold, the PDCP entity can deliver the data to the primary RLC entity or the secondary RLC entity.
终端设备向网络设备发送数据时,由于上行(uplink,UL)包延迟预算(packet delay budget,PDB)通常比产生数据的周期更长,终端设备的PDCP实体可以将先后到达的数据保存在缓存中。When a terminal device sends data to a network device, since the uplink (UL) packet delay budget (PDB) is usually longer than the period for generating data, the PDCP entity of the terminal device can save the data that arrives successively in the cache.
示例性的,以上行增强现实(augmented reality,AR)业务为例,如下述表1所示,该上行AR业务具备如下流量特点,基于该流量特点,可知该上行AR业务的上行PDB比产生业务数据的周期更长:For example, taking an uplink augmented reality (AR) service as an example, as shown in Table 1 below, the uplink AR service has the following traffic characteristics. Based on the traffic characteristics, it can be known that the uplink PDB of the uplink AR service is longer than the period for generating service data:
表1
Table 1
Table 1
终端设备的PDCP实体根据数据量大小向主RLC实体或副RLC实体递交数据时,可能会将先到达的数据(或者描述为老的数据、老的PDU、老的PDU集合等)和后到达的数据(或者描述为新的数据、新的PDU、新的PDU集合等)递交给相同的RLC实体(或者描述为映射到相同的逻辑信道),即先到达的数据和后到达的数据可能会被以相同的方式进行处理,进而可能会导致某些数据超过自身的PDB需求,降低数据传输可靠性。When the PDCP entity of the terminal device delivers data to the primary RLC entity or the secondary RLC entity according to the data volume, the data that arrives first (or is described as old data, old PDU, old PDU set, etc.) and the data that arrives later (or is described as new data, new PDU, new PDU set, etc.) may be delivered to the same RLC entity (or described as being mapped to the same logical channel), that is, the data that arrives first and the data that arrives later may be processed in the same way, which may cause some data to exceed its own PDB requirements, thereby reducing the reliability of data transmission.
即上述数据递交过程中,PDCP实体无法将先到达的数据和后到达的数据分开,无法对不同的数据进行区别处理。That is, during the above data delivery process, the PDCP entity cannot separate the data that arrives first from the data that arrives later, and cannot process different data differently.
所以,终端设备的PDCP实体如何向RLC实体递交数据,以满足数据的PDB需求,降低数据传输时延,提高数据传输可靠性成为亟待解决的技术问题。Therefore, how the PDCP entity of the terminal device delivers data to the RLC entity to meet the PDB requirements of the data, reduce data transmission delay, and improve data transmission reliability has become a technical problem that needs to be solved urgently.
为了解决上述技术问题,本申请实施例提供了一种通信方法,该方法中,终端设备的第一PDCP实体可以获取一个或多个数据集合,并向数据集合关联的RLC实体递交数据集合;其中,终端设备包括多个PDCP实体,多个PDCP实体包括第一PDCP实体,不同PDCP实体获取不同重要性等级的数据集合;第一PDCP实体关联多个RLC实体,不同的数据集合关联不同的RLC实体。In order to solve the above-mentioned technical problems, an embodiment of the present application provides a communication method, in which a first PDCP entity of a terminal device can obtain one or more data sets and submit the data sets to an RLC entity associated with the data sets; wherein the terminal device includes multiple PDCP entities, the multiple PDCP entities include a first PDCP entity, and different PDCP entities obtain data sets of different importance levels; the first PDCP entity is associated with multiple RLC entities, and different data sets are associated with different RLC entities.

When each PDCP entity processes the acquired data set, different data sets can also be submitted to different RLC entities to achieve differentiated processing of different data sets, thereby meeting the packet delay budget PDB requirements of the data set, reducing data transmission delay, and improving data transmission reliability.

In addition, in addition to the devices shown in Figure 3, the communication system may also include other devices. The names of each device and each link in Figure 3 are not limited.

基于上述图3或图4所示通信系统,终端设备可以通过网络设备、核心网设备与数据网络中的应用服务器进行通信。Based on the communication system shown in FIG. 3 or FIG. 4 , the terminal device can communicate with the application server in the data network through the network device and the core network device.
示例性的,终端设备与应用服务器进行数据传输时,可以采用下述图5或图6中的任一网络架构进行数据传输。Exemplarily, when a terminal device and an application server perform data transmission, any network architecture shown in FIG. 5 or FIG. 6 can be used for data transmission.
如图5所示,用户面网元接收应用服务器发送的数据后,可以采用不同的数据流(如不同的QoS流)向网络设备发送不同的数据;网络设备也可以采用不同的数据流(如不同的数据无线承载(data radio bearer,DRB)或不同的逻辑信道(logical channel,LCH))向终端设备发送不同的数据。As shown in Figure 5, after the user-side network element receives the data sent by the application server, it can use different data streams (such as different QoS streams) to send different data to the network device; the network device can also use different data streams (such as different data radio bearers (DRB) or different logical channels (LCH)) to send different data to the terminal device.
其中,应用服务器可以采用不同的数据流(如互联网协议(internet protocol,IP)流)向用户面网元发送不同的数据;也可以采用同一数据流向用户面网元传输不同的数据。当应用服务器采用同一数据流向用户面网元传输不同的数据时,用户面网元可以对接收到的数据进行区分,通过不同的数据流(如不同的QoS流)向网络设备传输不同的数据。Among them, the application server can use different data streams (such as Internet protocol (IP) streams) to send different data to the user plane network element; it can also use the same data stream to transmit different data to the user plane network element. When the application server uses the same data stream to transmit different data to the user plane network element, the user plane network element can distinguish the received data and transmit different data to the network device through different data streams (such as different QoS streams).
需要说明的是,不同的数据可以是不同优先级的数据,也可以是不同类型的数据,也可以是其他不同的数据,不予限制。应用服务器与用户面网元之间的数据流、用户面网元与网络设备之间的数据流、网络设备与终端设备之间的数据流可以表示不同的含义,如应用服务器与用户面网元之间的数据流可以是互联网协议(internet protocol,IP)流,用户面网元与网络设备之间的数据流可以是QoS流,网络设备与终端设备之间的数据流可以是DRB或LCH等,不予限制。It should be noted that different data can be data of different priorities, data of different types, or other different data, without restriction. The data flow between the application server and the user-plane network element, the data flow between the user-plane network element and the network device, and the data flow between the network device and the terminal device can represent different meanings. For example, the data flow between the application server and the user-plane network element can be an Internet protocol (IP) flow, the data flow between the user-plane network element and the network device can be a QoS flow, and the data flow between the network device and the terminal device can be a DRB or LCH, etc., without restriction.
与图5中用户面网元采用不同的数据流向网络设备传输不同的数据所不同的是,如图6所示,用户面网元也可以采用同一数据流(如同一QoS流)向网络设备传输不同的数据,网络设备接收到用户面网元发送的数据后,可以对数据进行区分,通过不同的数据流(如不同的DRB或不同的LCH)向终端设备传输不同的数据。Different from the user plane network element in Figure 5 that uses different data streams to transmit different data to the network device, as shown in Figure 6, the user plane network element can also use the same data stream (such as the same QoS stream) to transmit different data to the network device. After the network device receives the data sent by the user plane network element, it can distinguish the data and transmit different data to the terminal device through different data streams (such as different DRBs or different LCHs).
上述图5至图6是以应用服务器向终端设备发送数据为例对网络架构进行描述,当终端设备向应用服务器发送数据时,例如,终端设备可以根据QoS流与DRB或LCH之间的映射关系,将应用层的数据映射到相应的DRB或LCH上进行传输。The above Figures 5 to 6 describe the network architecture by taking the application server sending data to the terminal device as an example. When the terminal device sends data to the application server, for example, the terminal device can map the application layer data to the corresponding DRB or LCH for transmission based on the mapping relationship between the QoS flow and the DRB or LCH.
示例性的,以上述图5中用户面网元与网络设备之间采用不同的QoS流传输不同的数据为例,终端设备的SDAP层可以接收应用层发送的关联不同QoS流的数据,SDAP实体可以向不同的PDCP实体递交关联不同QoS流的数据,PDCP实体可以向自身关联的RLC实体递交接收到的数据。For example, taking the example of using different QoS streams to transmit different data between the user plane network element and the network device in the above Figure 5, the SDAP layer of the terminal device can receive data associated with different QoS streams sent by the application layer, the SDAP entity can submit data associated with different QoS streams to different PDCP entities, and the PDCP entity can submit the received data to the RLC entity associated with itself.
例如,如图7所示,以SDAP实体接收应用层发送的关联QoS流1的数据和关联QoS流2的数据
为例,SDAP实体可以向PDCP实体1递交关联QoS流1(或者描述为关联QoS流标识1(QoS flow identifier 1,QFI 1))的数据,向PDCP实体2递交关联QoS流2(或者描述为关联QFI 2)的数据。PDCP实体1向自身关联的RLC实体递交关联QoS流1的数据。PDCP实体2向自身关联的RLC实体递交关联QoS流2的数据。For example, as shown in FIG. 7 , the SDAP entity receives data associated with QoS flow 1 and data associated with QoS flow 2 sent by the application layer. For example, the SDAP entity may deliver data associated with QoS flow 1 (or described as associated QoS flow identifier 1 (QFI 1)) to PDCP entity 1, and deliver data associated with QoS flow 2 (or described as associated QFI 2) to PDCP entity 2. PDCP entity 1 delivers data associated with QoS flow 1 to the RLC entity associated with itself. PDCP entity 2 delivers data associated with QoS flow 2 to the RLC entity associated with itself.
上述图7所示的协议架构中,终端设备的SDAP实体可以关联多个PDCP实体,当为终端设备配置分裂RB时,PDCP实体也可以关联多个RLC实体,该图7所示的协议架构也可以称为协议架构A。In the protocol architecture shown in FIG. 7 above, the SDAP entity of the terminal device can be associated with multiple PDCP entities. When a split RB is configured for the terminal device, the PDCP entity can also be associated with multiple RLC entities. The protocol architecture shown in FIG. 7 can also be referred to as protocol architecture A.
又一种示例中,以上述图6中用户面网元与网络设备之间采用不同的QoS流传输不同的数据为例,终端设备的SDAP层可以接收应用层发送的关联不同QoS流的数据,SDAP实体可以向同一PDCP实体递交关联不同QoS流的数据,PDCP实体可以向自身关联的不同RLC实体递交关联不同QoS流的数据。In another example, taking the example of using different QoS streams to transmit different data between the user plane network element and the network device in Figure 6 above, the SDAP layer of the terminal device can receive data associated with different QoS streams sent by the application layer, the SDAP entity can submit data associated with different QoS streams to the same PDCP entity, and the PDCP entity can submit data associated with different QoS streams to different RLC entities associated with itself.
例如,如图8所示,以SDAP实体接收应用层发送的关联QoS流1的数据和关联QoS流2的数据为例,SDAP实体可以向PDCP实体递交关联QoS流1(或者描述为关联QFI 1)的数据和关联QoS流2(或者描述为关联QFI 2)的数据。PDCP实体可以向自身关联的RLC实体1递交关联QoS流1的数据,向自身关联的RLC实体2递交关联QoS流2的数据。For example, as shown in FIG8 , taking the case where the SDAP entity receives data of the associated QoS flow 1 and data of the associated QoS flow 2 sent by the application layer, the SDAP entity may deliver data of the associated QoS flow 1 (or described as associated QFI 1) and data of the associated QoS flow 2 (or described as associated QFI 2) to the PDCP entity. The PDCP entity may deliver data of the associated QoS flow 1 to the RLC entity 1 associated with itself, and deliver data of the associated QoS flow 2 to the RLC entity 2 associated with itself.
上述图8所示的协议架构中,终端设备的SDAP实体可以关联一个PDCP实体,当为终端设备配置分裂RB时,PDCP实体可以关联多个RLC实体,该图8所示的协议架构也可以称为协议架构B。In the protocol architecture shown in FIG. 8 above, the SDAP entity of the terminal device can be associated with one PDCP entity. When the split RB is configured for the terminal device, the PDCP entity can be associated with multiple RLC entities. The protocol architecture shown in FIG. 8 can also be referred to as protocol architecture B.

基于上述图12所示的方法,PDCP实体对获取到的数据集合进行处理时,不仅可以将不同重要性等级的数据集合递交给不同的逻辑信道/RLC实体,还可以将同一数据集合中不同重要等级的数据递交给不同的逻辑信道/RLC实体。实现对不同数据集合或不同数据的区别处理,从而满足数据集合或数据的包延迟预算PDB需求,降低数据传输时延,提高数据传输可靠性。Based on the method shown in FIG. 12 above, when the PDCP entity processes the acquired data set, it can not only deliver data sets of different importance levels to different logical channels/RLC entities, but also deliver data of different importance levels in the same data set to different logical channels/RLC entities. Different processing of different data sets or different data is achieved, thereby meeting the packet delay budget PDB requirements of the data set or data, reducing data transmission delay, and improving data transmission reliability.
