配置数据流的方法和装置
相关申请的交叉引用
本申请主张在2018年4月2日在中国提交的中国专利申请号No.201810284187.0的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信领域,尤其涉及一种配置数据流的方法和装置。
背景技术
第五代(5 th-Generation,5G)移动通信系统引入了服务质量(Quality-of-Service,QoS)的网络侧指示机制,因此需要在上行和下行数据的发送过程中都需要加入用户设备(User Equipment,UE)的IP数据流的QoS指示信息(如QoS flow ID),而该协议层则位于包数据汇聚协议(Packet Data Convergence Protocol,PDCP)层之上,如图1所示,其中1个服务数据适应协议(Service Data Adaptation Protocol,SDAP)实体对应1个高层的协议数据单元(Protocol Data Unit,PDU)会话(Session),而一个SDAP实体则可以将数据流(flow)发送给多个不同的数据无线承载(Date Resource Bearer,DRB),对应于图1所示的多个PDCP实体。
由于网络侧能够将终端设备的一个数据流(比如QoS数据流1)的接收端或者发送端的DRB进行重新配置(比如发生切换时),即将接收端或者发送端的DRB从DRB1(即源DRB)变换到DRB2(也就是目标DRB)。
然而,当SDAP实体的接收端或者发送端对应的DRB从源DRB变换到目标DRB之后,由于不同DRB中的数据流到达接收端会有先后顺序,而如何保证让将接收到的数据流在递交给高层协议实体时也能够按照其达到接收端的先后顺序来递交,仍亟待解决。

具体实施方式
为了使本技术领域的人员更好地理解本申请中的技术方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,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,都应当属于本申请保护的范围。
本申请的技术方案,可以应用于各种通信系统,例如:全球移动通讯系统(Global System of Mobile communication,GSM),码分多址(Code Division Multiple Access,CDMA)系统,宽带码分多址(Wideband Code Division Multiple Access,WCDMA),通用分组无线业务(General Packet Radio Service,GPRS),长期演进(Long Term Evolution,LTE)/增强长期演进(Long Term Evolutionadvanced,LTE-A),NR(New Radio)等。
用户设备(User Equipment,UE),也可称之为移动终端(Mobile Terminal)、移动用户设备等,可以经无线接入网(例如,Radio Access Network,RAN)与一个或多个核心网进行通信,用户设备可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。
基站,可以是GSM或CDMA中的基站(Base Transceiver Station,BTS), 也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(eNB或e-NodeB,evolutional Node B)及5G基站(gNB),本申请并不限定,但为描述方便,下述实施例以gNB为例进行说明。
如背景技术中所述,相关技术中的QoS数据流对应的DBR发生变换时,比如从DBR1(即源DBR)变换到DBR2(即目标DBR)时,由于通过不同DBR传输的数据到达接收端的顺序不同,而如何保证通过不同DBR传输的数据到达接收端后,接收端还能够按照这些通过不同DBR传输的数据的到达顺序递交(也就是发送)至其他协议层实体也就是高层协议实体(如IP层),仍需要一种解决方案,因此,在相关技术的基础上,有必要提出一种配置数据流的方法,针对QoS数据流对应的DBR发生变换的情况,保证通过不同DBR传输的数据能够在到达接收端后仍然按照其到达顺序依次被递交到高层协议实体。
为了解决这个问题,本公开实施例中可以预先通过网络侧配置或协议约定SDAP实体的特定配置信息,该特定配置信息可以包括下述一项或多项的任意组合:①携带SDAP包头的指示信息;②是否发送指示信息;③指示信息的发送次数。
图2是本公开的一个实施例提供的一种配置数据流的方法的实施流程示意图。图2的方法由SDAP实体发送端执行。该方法包括:
步骤101,若QoS数据流对应的DRB由源DRB变换到目标DRB,向SDAP实体接收端发送指示信息。
其中,上述指示信息用于指示第一QoS数据流在源DRB被发送完成或者第二QoS数据流的数据在目标DRB开始被发送,上述QoS数据流的数据包括第一QoS数据流的数据和第二QoS数据流的数据。
可选地,上述所述指示信息的格式为以下格式中的一种:格式1,没有携带数据部分SDAP包头;格式2,包含至少一个预留指示比特的SDAP包头;格式3,包含至少一个预留指示比特的SDAP包头,且该包含至少一个预留指示比特的SDAP包头为控制包;其中,预留指示比特用于指示上述所述的指示信息。
当上述指示信息的格式格式1,为没有携带数据部分的SDAP包头时, 若SDAP实体接收端接收到来自SDAP实体发送端发送的一个SDAP数据包,该SDAP数据包为没有携带数据部分的SDAP包头,则表明SDAP实体接收端接收到了上述所述的指示信息。如图3所示,为根据本公开实施例提供的指示信息格式为没有携带数据部分的SDAP包头时的示意图,图3为一个字节(Octet,简称Oct)的数据示意图,该Oct1包括8个比特(bit),其中,前两个bit(图示R)为预留bit,取值为0,剩余的六个bit(图示QFI)用于指示QoS数据流ID。
当上述指示信息的格式为格式2,为包含指示一个预留指示比特的SDAP包头时,若SDAP实体接收端接收到来自SDAP实体发送端发送的一个SDAP数据包,该SDAP数据包为包含至少一个预留指示比特的SDAP包头,则表明SDAP实体接收端接收到了上述所述的指示信息。如图4所示,为根据本公开实施例提供的指示信息格式为格式2时的示意图,图4(a)为一个Oct的数据示意图,其中,第一个bit(图示R)为预留bit,取值为0,第二个bit(图示E)为预留指示比特,取值为1,剩余的六个bit(图示QFI)用于指示QoS数据流ID。图4(b)为两个Oct的数据示意图,其中Oct1中的8个bit与图4(a)相同,Oct2为所携带的数据部分(图示Data)。也就是说,当上述指示信息的格式为格式2时,该SDAP数据包可以不携带数据部分,也可以携带数据部分。
当上述指示信息的格式为格式3,为包含至少一个预留指示比特的SDAP包头,且该包含至少一个预留指示比特的SDAP包头为控制包时,若SDAP实体接收端接收到来自SDAP实体发送端发送的一个SDAP数据包,该SDAP数据包为包含至少一个预留指示比特的SDAP包头,且该SDAP数据包为控制包,则表明SDAP实体接收端接收到了上述所述的指示信息。如图5所示,为根据本公开实施例提供的指示信息格式为格式3时的示意图,图5为一个Oct的数据示意图,其中,第一个bit(图示C/D)为用于指示该SDAP数据包是数据包还是控制包的bit,取值为0时,表明该SDAP数据包为数据包,取值为1时,表明该SDAP数据包为控制包,第二个bit(图示E)为预留指示比特,取值为1,剩余的六个bit(图示QFI)用于指示QoS数据流ID。也就是说,当上述指示信息的格式为格式3时,只有满足C/D取值为1即为控 制包,且同时满足预留指示比特E取值为1时,该指示信息才生效。
应理解,由于源DBR或者目标DBR的RLC实体的工作模式包括确认模式(AM)、非确认模式(UM)和透明模式(TM)三种工作模式,本公开实施例为了保证数据传输的可靠性,提供一种优选的方案,即可以基于用于发送指示信息的DRB的无线链路控制层协议(Radio Link Control,RLC)实体的工作模式,确定指示信息的发送次数;其中,用于发送指示信息的DRB为源DRB或目标DRB。
基于DRB的RLC实体的工作模式,确定指示信息的发送次数,具体来说,若用于发送指示信息的DRB的RLC实体的工作模式为AM,由于AM模式本身能够保证数据传输的可靠性,因此可以确定指示信息的发送次数为1次;而若DRB的RLC实体的工作模式为UM或者TM,由于这两种工作模式本身不能够保证数据传输的可靠性,因此可以确定指示信息的发送次数为N次,N为大于1的正整数,也就是说在这两种工作模式下,可以向SDAP实体的接收端重复发送多次指示信息,以保证指示信息能够被SDAP实体的接收端接收到。
其中,上述N的取值可以包括以下几种情况:N等于预设发送次数;N小于预设发送次数;N小于或等于预设发送次数;N大于预设发送次数;N大于或等于预设发送次数;这里所述的预设发送次数为通过协议配置或者网络侧设备预先配置的。
可选地,由于QoS数据流对应的DRB由源DRB变换到目标DRB通常是终端设备发生切换的瞬间,因此这个过程往往较短,为了便于避免繁琐的操作和实现,向SDAP实体接收端发送指示信息,具体可以向SDAP实体接收端发送M次指示信息,M为大于或等于1的正整数。这里当M为大于1的正整数的情况时,为保证数据传输的可靠性,不论DRB的RLC实体的工作模式处于AM、UM还是TM,均可以向SDAP实体接收端重复多次(M次)发送指示信息。
其中,上述M的取值可以包括以下几种情况:M等于预设发送次数;M小于预设发送次数;M小于或等于预设发送次数;M大于预设发送次数;M大于或等于预设发送次数;这里所述的预设发送次数为通过协议配置或者网 络侧设备预先配置的。
可选地,向SDAP实体接收端发送指示信息,可以在下述两种条件下触发:条件1,没有存储QoS数据流的数据;条件2,存储有QoS数据流的数据时,在将该QoS数据流中的最后一个数据发送给源DRB之后。也就是说,若满足条件1,即若没有存储QoS数据流的数据,则向SDAP实体接收端发送指示信息;若满足条件2,即若存储有QoS数据流的数据,在将QoS数据流中的最后一个数据发送给源DRB之后,向SDAP实体接收端发送指示信息。
应理解,本公开实施例还可以通过目标DRB发送第二QoS数据流的数据。具体来说,通过目标DRB发送第二QoS数据流的数据,包括以下两种情况:情况1,若开始发送指示信息,则通过目标DRB发送第二QoS数据流的数据;情况2,若完成发送指示信息,则通过目标DRB发送所述第二QoS数据流的数据。此外,在确定了QoS数据流对应的DRB由源DRB变换到目标DRB,也可以立即通过目标DRB发送第二QoS数据流的数据。
可选地,本公开实施例中向SDAP实体接收端发送指示信息,具体既可以通过源DRB向SDAP实体接收端发送指示信息,也可以通过目标DRB向SDAP实体接收端发送指示信息。
本公开的实施例中,SDAP实体发送端能够在QoS数据流对应的DRB由源DRB变换到目标DRB时,向SDAP实体接收端发送指示信息,该指示信息能够用于指示第一数据流在源DRB被发送完成或者第二QoS数据流在目标DRB开始被发送,使得SDAP实体接收端在接收到该指示信息之后能够对通过源DRB和通过目标DRB接收的QoS数据流进行区分处理,从而保证SDAP实体接收端将接收到的QoS数据流按照其到达接收端的先后顺序来依次递交给高层协议实体。
图6是本公开的一个实施例提供的另一种配置数据流的方法的实施流程示意图。图6的方法由SDAP实体接收端执行。该方法包括:
步骤201,若QoS数据流对应的DRB由源DRB变换到目标DRB,接收来自SDAP实体发送端的指示信息,指示信息用于指示QoS数据流的数据在所述源DRB的数据被发送完成或者QoS数据流的数据在目标DRB开始被发送。
可选地,在这种情况下,还可以接收QoS数据流的数据;将再QoS数据流的数据发送给其他协议层实体。而由于QoS数据流对应的DRB由源DRB变换到目标DRB,这将会导致QoS数据流中的部分数据会通过源DRB接收,另一部分会通过目标DRB接收,为便于描述,可以将这两部分数据称为第一QoS数据流和第二QoS数据流,因此,QoS数据流包括第一QoS数据流和第二QoS数据流。
因此,接收QoS数据流的数据包括:通过源DRB接收第一QoS数据流的数据;以及,通过目标DRB接收第二QoS数据流的数据。
可选地,将QoS数据流的数据发送给其他协议层实体,具体来说,可以首先将第一QoS数据流的数据按照第一QoS数据流中的数据接收顺序依次发送给其他协议层实体;然后,再将第二QoS数据流的数据按照第二QoS数据流中的数据接收顺序依次发送给其他协议层实体。也就是说,将先接收到的数据(即通过源DRB接收到的第一QoS数据流中的数据)先递交到其他协议层实体。
可选地,上述接收来自SDAP实体发送端的指示信息,既可以通过源DRB接收来自SDAP实体发送端的指示信息,也可以通过目标DRB接收指示信息。
由于在接收了QoS数据流的数据之后,还需要将QoS数据流的数据递交给其他协议层,因此还可以存储第一QoS数据流的数据和第二QoS数据流的数据。而为便于区分第一QoS数据流和第二QoS数据流中数据的接收顺序,并在将这些数据递交到其他协议层实体(如高层协议实体IP层)时,还能够保证按照这些数据的接收顺序来依次递交,本公开实施例在存储第一QoS数据流和第二QoS数据流时,具体可以按照第一QoS数据流和第二QoS数据流中的数据接收顺序存储第一QoS数据流的数据和第二QoS数据流的数据。
由于第一QoS数据流和第二QoS数据流分别是通过源DRB和目标DRB接收到的,因此第一QoS数据流中的数据比第二QoS数据流中的数据在接收顺序上要靠前一些,那么为了便于区分这两个QoS数据流,可以通过以下两种方式来进行存储:一方面,可以将第一QoS数据流的数据存储在第一存储位置,将第二QoS数据流的数据存储在第二存储位置;另一方面,也可以将第一QoS数据流的数据和第二QoS数据流的数据存储在目标存储位置(也就 是存储在同一位置),并为第一QoS数据流的数据和第二QoS数据流的数据分配不同的标签。
本公开的实施例中,SDAP实体接收端能够在QoS数据流对应的DRB由源DRB变换到目标DRB时,接收来自SDAP实体发送端的指示信息,该指示信息能够用于指示第一数据流在源DRB被发送完成或者第二QoS数据流在目标DRB开始被发送,使得SDAP实体接收端在接收到该指示信息之后能够对通过源DRB和通过目标DRB接收的QoS数据流进行区分处理,从而保证SDAP实体接收端将接收到的QoS数据流按照其到达接收端的先后顺序来依次递交给高层协议实体。
图7是本公开的一个实施例提供的再一种配置数据流的方法的实施流程示意图。图7的方法由SDAP实体接收端执行。该方法包括:
步骤301,若QoS数据流对应的DRB由源DRB变换到目标DRB,该QoS数据流的数据包括第一QoS数据流的数据和第二QoS数据流的数据,通过源DRB接收第一QoS数据流的数据,通过目标DRB接收第二QoS数据流的数据;
步骤302,基于预设的数据处理规则,对QoS数据流的数据进行数据处理;
其中,预设的数据处理规则至少包括:不将QoS数据流的数据递交到其他协议层实体;不将第二QoS数据流的数据发送给其他协议层实体,将第一QoS数据流的数据按照第一QoS数据流中的数据接收顺序依次发送给其他协议层实体;存储第一QoS数据流的数据和第二QoS数据流的数据。
可选地,为便于区分第一QoS数据流和第二QoS数据流中数据的接收顺序,并在将这些数据递交到(也就是发送)其他协议层实体(如高层协议实体IP层)时,还能够保证按照这些数据的接收顺序来依次递交,本公开实施例在存储第一QoS数据流和第二QoS数据流时,具体可以按照第一QoS数据流和第二QoS数据流中的数据接收顺序存储第一QoS数据流的数据和第二QoS数据流的数据。
由于第一QoS数据流和第二QoS数据流分别是通过源DRB和目标DRB接收到的,因此第一QoS数据流中的数据比第二QoS数据流中的数据在接收 顺序上要靠前一些,那么为了便于区分这两个QoS数据流,可以通过以下两种方式来进行存储:一方面,可以将第一QoS数据流的数据存储在第一存储位置,将第二QoS数据流的数据存储在第二存储位置;另一方面,也可以将第一QoS数据流的数据和第二QoS数据流的数据存储在目标存储位置(也就是存储在同一位置),并为第一QoS数据流的数据和第二QoS数据流的数据分配不同的标签。
本公开实施例中,SDAP实体接收端能够在QoS数据流对应的DRB由源DRB变换到目标DRB时,通过源DRB接收第一QoS数据流,通过所述目标DRB接收所述第二QoS数据流之后,能够基于预设的数据处理规则对QoS数据流进行数据处理,以将第一QoS数据流和第二QoS数据流区分处理,从而保证SDAP实体接收端将接收到的QoS数据流按照其到达接收端的先后顺序来依次递交给高层协议实体。
