步骤201:接收网络侧设备发送的第一消息,所述第一消息用于指示目标业务的传输路径从第一传输路径变更至第二传输路径。
本申请实施例中,第一终端可以理解为图1中的终端11。
在通信技术领域,业务一般包括多播业务,例如多媒体广播多播业务(Multimedia Broadcast and Multicast Service,MBMS)、广播多播业务(Multicast Broadcast Service,MBS)和单播业务。
MBMS一般通过以下两种方式传输:其一,在MBMS单频网(Multimedia Broadcast multicast service Single Frequency Network,MBSFN)子帧中通过物理多播信道(Physical Multicast Channel,PMCH)物理信道传输,其中,控制信息通过系统信息(如SIB13)和广播控制信道(Multicast Control Channel,MCCH)传输,数据通过广播业务信道(Multicast Traffic Channel,MTCH)传输。其二,通过物理下行控制信道(Physical Downlink Control Channel, PDCCH)调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)信道传输,其中,控制信息通过系统信息(如SIB20)和单小区广播控制信道(Single Cell Multicast Control Channel,SC-MCCH)传输,数据通过单小区广播业务信道(Single Cell Multicast Traffic Channel,SC-MTCH)传输。其中,SC-MCCH通过单小区无线网络临时标识(Single Cell Radio Network Temporary Identity,Single Cell RNTI,SC-RNTI)PDCCH调度的PDSCH传输,SC-MTCH通过G-RNTI PDCCH调度的PDSCH传输。MBS业务一般通过特定的MBMS无线承载(MBMS Radio Bearer,MRB)传输,MBS业务可以通过临时移动组标识(Temporary Mobile Group Identity,TMGI)和QoS flow ID等标识标记。单播业务一般通过特定的单播数据无线承载(Data Radio Bearer,DRB)传输。
本申请实施例中,目标业务可以理解为特定业务,目标业务既可以是多播业务,也可以是单播业务,网络侧设备可以通过指示信息来指示目标业务。网络侧设备可通过第一消息来指示目标业务,即,第一消息可包括目标业务的指示信息。用于指示目标业务的指示信息可以包括会话标识(如PDU Session-1)、数据流标识(如QoS flow-1)和多播业务标识(如TMGI-1)中的至少一项。
本申请实施例中,目标业务的传输路径的变更既可以包括目标业务的发送路径的变更,也可以包括目标业务的接收路径的变更。也就是说,网络侧设备既可以通过第一消息来指示目标业务的发送路径从第一发送路径变更至第二发送路径,这样,网络侧设备可通过第二发送路径向终端发送目标业务的数据,终端可通过第二发送路径对应的接收路径接收网络侧设备发送的目标业务的数据。网络侧设备也可以通过第一消息来指示目标业务的接收路径从第一接收路径变更至第二接收路径,这样,网络侧设备可通过第二接收路径对应的发送路径向终端发送目标业务的数据,终端可通过第二接收路径接收网络侧设备发送的目标业务的数据。
本申请实施例中,第一传输路径也可称之为源路径(如源接收路径或源发送路径或源承载等表述),第二传输路径也可称之为目标路径(如目标接收路径或目标发送路径或目标承载等表述)。
本申请实施例中,无论目标业务是单播业务还是多播业务,第一传输路径既可以为单播传输方式的传输路径,也可以为多播传输方式的传输路径;相应的,第二传输路径既可以为单播传输方式的传输路径,也可以为多播传输方式的传输路径。
可选的,所述第一传输路径为单播传输方式的传输路径,所述第二传输路径为多播传输方式的传输路径。例如,第一传输路径为DRB,第二传输路径为MRB。又例如,第一传输路径为RB-1(Radio Bearer-1,无线承载-1)的单播接收无线链路控制(Radio Link Control,RLC)实体,第二传输路径为RB-1的多播接收RLC实体。
可选的,所述第一传输路径为多播传输方式的传输路径,所述第二传输路径为单播传输方式的传输路径。例如,第一传输路径为MRB,第二传输路径为DRB。又例如,第一传输路径为RB-1的多播RLC接收实体,第二传输路径为RB-1的单播RLC接收实体。
可选的,所述第一传输路径和所述第二传输路径分别为不同无线承载的传输路径。例如,第一传输路径为MRB-1,第二传输路径为DRB-1;或者,第一传输路径为DRB-2,第二传输路径为MRB-2。
可选的,所述第一传输路径和所述第二传输路径为同一无线承载的不同传输路径。例如,承载1有1个分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)接收实体,该PDCP接收实体关联了2个RLC接收实体,其中RLC-1对应第一传输路径,RLC-2对应第二传输路径。
作为示例,步骤201中,网络侧设备向终端发送的第一消息可用于指示终端将MRB-1中的TMGI-1的多播业务变更到DRB-1中进行接收。
步骤202:对所述目标业务的第一数据进行处理之后,再对所述目标业务的第二数据进行处理;所述目标业务的第一数据为所述第一终端在所述第一传输路径接收的数据,所述目标业务的第二数据为所述第一终端在所述第二传输路径接收的数据。
本申请实施例中,第一终端先对在第一传输路径接收的数据进行处理,再对在第二传输路径接收的数据进行处理,这样,在目标业务的传输路径发生变更的时候,能够确保第一终端按照目标业务的数据接收顺序依次对目标 业务的数据进行处理,从而能够减少数据丢失,避免接收数据的中断。
可选的,所述对所述目标业务的第一数据进行处理,包括:
对所述目标业务的第一数据进行处理并递交至高层协议实体。
可选的,所述对所述目标业务的第一数据进行处理并递交至高层协议实体,包括以下任一项:
将所述第一传输路径的无线链路控制RLC实体进行重建;
通过RLC实体对所述目标业务的第一数据进行处理,并将处理后的所述目标业务的第一数据递交至高层协议实体;
将所述第一传输路径的分组数据汇聚协议PDCP实体进行重建;
通过PDCP实体对所述目标业务的第一数据进行处理,并将处理后的所述目标业务的第一数据递交至高层协议实体。
该实施方式中,第一终端可以对第一传输路径的RLC实体进行重建,也可以不对第一传输路径的RLC实体进行重建,而是将缓存的目标业务的第一数据进行处理后再将完整的RLC SDU数据递交至高层协议实体。第一终端也可以对第一传输路径的PDCP实体进行重建,也可以不对第一传输路径的PDCP实体进行重建,而是将缓存的目标业务的第一数据进行处理后递交至高层协议实体。
可选的,所述对所述目标业务的第一数据进行处理并递交至高层协议实体,包括以下至少一项:
忽略所述第一终端在所述第一传输路径未接收到的数据;
将所述第一终端缓存的数据进行处理并递交至高层协议实体;
丢弃所述第一终端在所述第一传输路径的第一个丢失的数据包,以及所述第一个丢失的数据包之后的数据包;
对所述第一个丢失的数据包之前的数据包进行处理并递交至高层协议实体。
该实施方式中,第一终端可以忽略第一终端在第一传输路径没有接收到的数据,并将第一终端缓存的数据处理后递交至高层协议实体。例如,第一终端的PDCP接收实体在第一传输路径接收到PDCP PDU-1/3,而没有接收到PDCP PDU-2,则PDCP接收实体可忽略PDCP PDU-2,将PDCP PDU-1/3处 理后,例如,将PDCP PDU-1/3解密或解压缩或移除PDCP PDU包头后再递交至PDCP接收实体的高层协议实体。
该实施方式中,第一终端可以对在第一传输路径的第一个丢失的数据包之前的数据包进行处理并递交至高层协议实体,并从第一个丢失的数据包开始,丢弃该数据包之后的所有数据包。例如,第一终端的PDCP接收实体在第一传输路径接收到PDCP PDU-1/3/5,PDCP PDU-2为第一个丢失的数据包,则PDCP接收实体将PDCP PDU-1处理后,例如,将PDCP PDU-1解密或解压缩或移除PDCP PDU包头后再递交至PDCP接收实体的高层协议实体,而将PDCP PDU-3/5丢弃。
可选的,所述目标业务的第二数据包括:
所述第一终端在所述第一传输路径的第一个丢失的数据包,以及所述第一个丢失的数据包之后的数据包;
所述第一终端在所述第一传输路径丢失的数据包;
N个终端在所述第一传输路径的第一个丢失的数据包中最早的数据包,以及所述最早的数据包之后的数据包,所述N个终端包括所述第一终端;
所述N个终端在所述第一传输路径的第一个丢失的数据包中最晚的数据包,以及所述最晚的数据包之后的数据包。
该实施方式中,当有多个终端向网络侧设备上报或反馈在第一传输路径的的目标业务的数据接收状态信息时,这多个终端上报的数据接收状态信息可能不同,例如,多个终端上报的在第一传输路径的第一个丢失的数据包可能不同。那么,在这种情况下,网络侧设备在第二传输路径发送的目标业务的第一数据可存在以下多种可能的情况。
其一,网络侧设备以多个终端在第一传输路径的第一个丢失的数据包中最早丢失的数据包为参考,将该最早丢失的数据包以及该最早丢失的数据包之后的数据包作为需要在第二传输路径上重传的数据。例如,UE-1上报其在第一传输路径的第一个丢失的数据包为数据包-1,UE-2上报其在第一传输路径的第一个丢失的数据包为数据包-2,则最早丢失的数据包为数据包-1,网络侧设备从数据包-1开始重传数据包。
其二,网络侧设备以多个终端在第一传输路径的第一个丢失的数据包中 最晚丢失的数据包为参考,将该最晚丢失的数据包以及该最晚丢失的数据包之后的数据包作为需要在第二传输路径上重传的数据。例如,UE-1上报其在第一传输路径的第一个丢失的数据包为数据包-1,UE-2上报其在第一传输路径的第一个丢失的数据包为数据包-2,则最晚丢失的数据包为数据包-2,网络侧设备从数据包-2开始重传数据包。
其三,网络侧设备将每个终端在第一传输路径丢失的数据包作为需要在第二传输路径上重传的数据。
该实施方式中,网络侧设备可以在第二传输路径向终端发送其在第一传输路径的第一个丢失的数据包之后的数据包,也就是说,从第一传输路径的第一个丢失的数据包开始,将包括该第一个丢失的数据包的后续所有数据包都通过第二传输路径进行发送。网络侧设备也可以在第二传输路径向第一终端发送其在第一传输路径丢失的全部数据包,而对于第一终端在第一传输路径接收成功的数据包,网络侧设备可不再重复发送。
可选的,所述对所述目标业务的第二数据进行处理,包括:
将所述目标业务的第二数据中满足预设条件的数据包丢弃。
该实施方式中,第一终端在接收到网络侧设备发送的目标业务的第二数据之后,可以将其中满足预设条件的数据包丢弃。具体的,第一终端可以根据网络侧设备所指示的目标业务的第二数据在第一传输路径所对应的数据包编号信息,从目标业务的第二数据中确定出满足预设条件的数据包。
可选的,所述满足预设条件的数据包包括以下任一项:
在所述第一传输路径递交至高层协议实体的数据包;
在所述第一传输路径被忽略接收的数据包。
其中,高层协议实体从上至下可依次包括业务数据适配协议(Service Data Adaptation Protocol,SDAP)、包数据汇聚协议(Packet Data Convergence Protocol,PDCP)、无线链路控制(Radio Link Control,RLC)和媒体接入控制(Media Access Control,MAC)。
由于网络侧设备通过第二传输路径可能会重传第一终端已在第一传输路径接收到的数据包,因此,对于这部分数据包,如果第一终端已经在第一传输路径递交至高层协议实体,则第一终端可以放弃这部分数据包,而不需要 再次递交至高层协议实体。另外,对于第一终端已经在第一传输路径忽略的数据包,那么即使网络侧设备通过第二传输路径进行重传,第一终端也可以放弃这部分数据包。
该实施方式中,通过将满足预设条件的数据包丢弃,能够使第一终端节省资源传输开销,提高了第一终端的通信性能。
可选的,在步骤201之后,所述方法还包括:
向所述网络侧设备发送第二消息,所述第二消息用于指示所述第一终端在所述第一传输路径对所述目标业务的接收状态。
上述第二消息可通过第一传输路径和第二传输路径中的至少一个传输路径传输,以提高第二消息的传输可靠性。假设第一消息用于指示目标业务的接收路径从第一接收路径变更至第二接收路径,那么,终端既可以通过第一接收路径对应的发送路径来发送第二消息。例如,终端可通过源DRB对应的上行发送RLC实体来发送第二消息,也可以通过目标DRB对应的上行发送RLC实体来发送第二消息,还可以通过源DRB和目标DRB对应的上行发送RLC实体来发送第二消息。
进一步的,第二消息对应的源路径的RLC实体的类型可以为非确认模式(Unacknowledged Mode,UM)和确认模式(Acknowledged Mode,AM)中的任一种,以进一步提高第二消息的传输可靠性。
该实施方式中,第一终端向网络侧设备发送第二消息的时机可以在接收到第一消息之后,也就是说,第一终端在接收到目标业务的传输路径发生变更的消息之后,第一终端可以向网络侧设备上报第二消息。由于第二消息用于指示第一终端在第一传输路径对目标业务的接收状态,第二消息可以理解为数据接收状态信息,因此,第一终端向网络侧设备上报第二消息,可以理解为,第一终端向网络侧设备上报在源接收路径的目标业务的数据接收状态。
该实施方式中,在目标业务的传输路径发生变更的情况下,通过第一终端向网络侧设备上报源接收路径的数据接收状态,能够使网络侧设备根据第一终端的数据接收状态,确定需要重传的目标业务的数据,从而能够有效地避免数据重复传输。
可选的,所述第二消息通过所述第一传输路径和所述第二传输路径中的 至少一个传输路径传输。
可选的,所述第二消息包括所述目标业务的数据包编号信息,所述目标业务的数据包编号信息用于指示所述第一终端在所述第一传输路径对所述目标业务的接收状态。
该实施方式中,通过目标业务的数据包编号信息来指示第一终端在第一传输路径对目标业务的接收状态,这种接收状态的指示方式具有简洁、直观、明了的特点。
可选的,所述目标业务的数据包编号信息包括以下任一项:
所述第一终端在所述第一传输路径的第一个丢失的数据包的编号信息;
所述第一终端在所述第一传输路径的第一个丢失的数据包的前一个数据包的编号信息;
所述第一终端在所述第一传输路径的第一个丢失的数据包的后一个数据包的编号信息;
所述第一终端在所述第一传输路径丢失的数据包的编号信息;
所述第一终端在所述第一传输路径接收的数据包的编号信息。
该实施方式中,第一个丢失的数据包的编号信息、第一个丢失的数据包的前一个数据包的编号信息以及第一个丢失的数据包的后一个数据包的编号信息,均可以理解为第一个丢失的数据包的编号信息。第一终端可以仅上报上述任一种第一个丢失的数据包的编号信息,而不上报第一个丢失的数据包的编号信息之外的其他数据包的接收状态信息,这样,对于网络侧设备而言,可以从第一个丢失的数据包开始重传所有的数据包。
该实施方式中,第二消息除了用于指示第一终端在第一传输路径对目标业务的接收状态,还可以包括第一传输路径的指示信息,例如,第二消息除了包括上述目标业务的数据包编号信息,还可以包括第一传输路径的指示信息。这样,网络侧设备即可通过第二消息区分第一终端上报的数据接收状态信息是针对在哪个第一传输路径的数据接收状态信息,从而能够使网络侧设备根据第二消息,更准确地确定需要在第二传输路径重传的数据。
可选的,所述第一传输路径的指示信息包括无线承载标识(如DRB-1)、数据流标识(如QoS flow-1)、会话标识(如PDU Session-1)、逻辑信道标识 (如LCID-1)、小区组标识(如主小区组(Master Cell Group,MCG)或辅小区组(Secondary Cell Group,SCG))和多播业务标识(如TMGI-1)中的至少一项。
可选的,所述方法还包括:
根据所述第二消息,调整所述第二传输路径的数据接收窗口的变量。
该实施方式中,数据接收窗口的变量包括数据接收窗口的上边界和下边界中的至少一项。由于第一终端是根据数据接收窗口的变量,例如数据接收窗口的下边界,来确定是否接收数据包,因此,第一终端根据第二消息调整第二传输路径的数据接收窗口的变量,能够使第一终端成功接收到网络侧设备在第二传输路径发送的目标业务的数据,避免数据包的丢失。
可选的,所述根据所述第二消息,调整所述第二传输路径的数据接收窗口的变量,包括:
将所述第二传输路径当前最后一个递交至高层协议实体的数据包的编号调整为第一编号,所述第一编号为所述第一终端在所述第一传输路径,第一个丢失的数据包的前一个数据包的编号或最后一个递交至高层协议实体的数据包的编号;或者,
将所述第二传输路径当前第一个待接收的数据包的编号调整为第二编号,所述第二编号为所述第一终端在所述第一传输路径,第一个丢失的数据包的编号。
该实施方式中,第一终端可以根据第一传输路径的第一个丢失的数据包的编号信息来调整第二传输路径的数据接收窗口的变量,也可以根据第一传输路径的最后一个递交至高层协议实体的数据包的编号信息来调整第二传输路径的数据接收窗口的变量。
通过上述调整,能够使网络侧设备在第二传输路径重传的数据包的编号位于数据接收窗口的范围内,从而能够确保第一终端成功接收到网络侧设备在第二传输路径重传的数据包,避免数据包的丢失。
可选的,在步骤201之后,所述方法还包括:
接收所述网络侧设备发送的第三消息,所述第三消息用于指示所述目标业务的第二数据在所述第一传输路径所对应的数据包编号信息。
该实施方式中,通过接收网络侧设备发送的第三消息,第一终端可通过第三消息知晓网络侧设备重传的数据包在第一传输路径所对应的编号信息,以使第一终端在第二传输路径接收网络侧设备重传的数据包时,能够根据其在第一传输路径所对应的编号信息,确定是接收还是丢弃这些数据包。
例如,假设网络侧设备在第二传输路径发送数据包1/2/3,该数据包1/2/3在第一传输路径的编号为4/5/6,则第三消息用于指示数据包1/2/3在第一传输路径的编号信息,即4/5/6。这样,第一终端就能够知晓网络侧设备在第二传输路径发送的数据包1/2/3,是对应原先在第一传输路径的数据包4/5/6。
