相关申请的交叉引用
本申请主张在2017年5月4日在中国提交的中国专利申请号No.201710308962.7的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术,尤其涉及一种状态报告的上报方法、终端及网络侧设备。
背景技术
为了解决对服务质量的要求,在无线链路控制(Radio Link Control,RLC)协议中引入了自动请求的重传(Automatic Repeat ReQuest,ARQ)机制,即发送端向接收端发送数据后,接收端会自动向发送端反馈RLC层状态报告。
另外,当接收端未成功接收发送端发送的所有数据,数据包存在丢失时,接收端返回的状态报告中不仅给出了接收到的数据包的编号,还要给出所有丢失的数据包的编号。
然而,由于状态报告中包括每个丢失的数据包的序号,因此当出现大量数据包的丢失时,会产生大量的控制信令,从而导致占用过多的无线资源。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合本公开的一 些实施例中的附图,对本公开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的一部分实施例,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“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本公开提供的状态报告的上报方法、终端及网络侧设备可以解决大量数据包丢失时,状态报告的信令开销大的问题
图1为本公开提供的状态报告上报方法所应用的系统的架构示意图。如图1所示,图1提供的系统架构包括:网络侧设备01和终端02。
其中,网络侧设备01可以是全球移动通讯(Global System of Mobile communication,GSM)或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)中的基站(NodeB,NB),还可以是长期演进LTE中的演进型基站(Evolutional Node B,eNB或eNodeB),还可以是新无线接入(New radio access technical,New RAT或NR)中的基站,或者中继站或接入点,或者未来第五代移动通信技术5G网络中的基站等,在此并不限定。
终端02可以是无线终端也可以是有线终端,该无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,无线终端可以是移动终端,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。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiation  Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment),在此不作限定。
图2为本公开的一些实施例的用户面协议栈架构示意图。如图2所示,终端的协议栈包括物理层(Physical Layer,PHY)、媒质接入控制(Medium Access Control,MAC)层、无线链路控制(Radio Link Control,RLC)层、分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层。网络侧设备的协议栈包括PHY、MAC层、RLC层、PDCP层。
在通信系统中,接收端在接收到不正确的业务数据时,需要发送端重传。按照图2协议栈从高层到低层的顺序,业务数据的重传分为:服务器重传、RLC层重传和物理层重传。物理层重传的是物理帧,RLC层重传的是RLC协议数据单元(Protocol Data Unit,PDU),服务器重传的是传输控制协议(Transfer Control Protocol,TCP)数据包。
对于RLC层而言,有3种业务模式:透传模式(Transparent Mode,TM)、非确认模式(Unacknowledged Mode,UM)和确认模式(Acknowledged Mode,AM)。只有确认模式的业务才有RLC层重传,其它模式的业务即使传输错误或丢失,也不会进行RLC层重传。
其中,AM以ARQ的方式为上层提供可靠的数据传输,保证数据正确地按序到达对端,可以适用于对时延不敏感,对错误敏感的业务。由于ARQ所针对的状态报告中包括每个丢失的数据包的编号,当出现大量数据包的丢失时,会产生大量的控制信令,从而导致占用过多的无线资源。在本公开的一些实施例中,提供一种状态报告的上报方法,状态报告中不需要携带每个丢失的数据包的编号,以减少控制信令所占用的无线资源。
在下述的各实施例中,为了便于描述状态报告的上报方法,将发送状态报告的一端称为发送端,将接收状态报告的一端称为接收端。
在发送端为终端时,接收端为网络侧设备,在发送端为网络侧设备时, 接收端为终端等。即终端既可以作为发送端,也可以作为接收端,网络侧设备即可以作为发送端,也可以作为接收端,本公开对发送端和接收端的具体实现方式不做特别限制。
图3为本公开的一些实施例提供的状态报告的上报方法的信令流程图。如图3所示,该方法包括S301-S304。
S301、发送端获取状态报告,状态报告中包括至少一个用于指示丢包指示信息的格式的格式指示位,以及格式指示位所指示的格式对应的丢包指示信息,丢包指示信息用于指示至少两个丢失的数据包。
发送端(可以理解为数据的接收端,状态报告的发送端)接收接收端(可以理解为数据的发送端,状态报告的接收端)发送的数据包。每个接收到的数据包都对应一个编号,该编号可以为数据包的序列号(Sequence Number,SN)。本领域技术人员可以理解,若接收到的数据包中不存在丢失的数据包,则接收到的数据包的编号为连续的编号。若在接收数据包的过程中,存在数据包的丢失,则接收到的数据包的编号为不连续的编号。
发送端根据接收到的数据包的编号,可以获知丢失的数据包的编号。发送端获取用于指示丢失的数据包的编号的状态报告。由上述描述可知,图3中所涉及的数据包为RLC PDU。其中,状态报告包括至少一个用于指示丢包指示信息的格式的格式指示位,以及格式指示位所指示的格式对应的丢包指示信息。该状态报告也是一种RLC PDU,且属于RLC的控制PDU。
图4为本公开的一些实施例提供的状态报告的结构示意图。如图4所示,每一行的长度为8比特,即1字节。其中,D/C:用来指示该状态报告是控制PDU还是数据PDU。CPT:RLC控制PDU的类型指示,用于指示该状态报告是控制PDU。E1、E2、E3、E4在取值为第一预设值时,例如为1时,为用于指示丢包指示信息的格式的格式指示位。E1、E2、E3、E4的取值为第二预设值,例如为0时,则不指示丢包指示信息的格式。以E1为例,即E1可以指示下一个丢包指示信息的格式是否为第一格式,若E1的取值为1,则是第一格式,若取值为0,则不是第一格式。状态报告中丢包指示信息可以采用的格式可以为协议预先约定的。
以E1和E2为例,E1的取值为1,用于指示丢包指示信息的格式为第一 格式,此时,E2、E3、E4的取值为0。当E2的取值为1时,用于指示丢包指示信息的格式为第二格式,此时E1、E3、E4的取值为0。在图4所示的示例中,该每个格式的丢包指示信息占用10比特。
本领域技术人员可以理解,针对第一格式的丢包指示信息之后的下一个丢包指示信息,不仅可以为图4所示的第二格式的丢包指示信息,还可以为E3或E4取值为1时所指示的丢包指示信息,或者还可以为E1所指示的丢包指示信息。对于下一个丢包指示信息所采用的格式,本公开此处不做特别限制,只要该格式对应的格式指示位的取值为预设值即可,该格式指示位的预设值可以是一个比特的预设值,也可以是多个比特组合所对应的多个值中的一个。
其中,图4的相关描述中每种格式的丢包指示信息用于指示至少两个丢失的数据包。例如,当丢失的数据包为连续的数据包时,该丢包指示信息可以包括丢失数据包的起始编号,即第一个丢失的数据包的序列号(First Missing SN,FMN)和丢失数据包的结束编号,即最后一个丢失的数据包的序列号(Last Missing SN,LMS)。或者,该丢包指示信息可以包括丢失数据包得起始编号和丢失数据包的数量。
再例如,当丢失的数据包不连续的数据包时,该丢包指示信息可以包括丢失数据包的起始编号、丢失数据包的结束编号以及丢失数据包的比特图。其中,比特图(Bitmap)的每1个bit对应1个数据包的编号(如比特值0代表丢失,比特值1代表成功接收)。
对于丢包指示信息用于指示至少两个丢失数据包的其它方式,都在本公开的保护范围内,本公开此处不再赘述。
本领域技术人员可以理解,在图4的相关描述中的丢包指示信息可以指示至少两个丢失的数据包。以起始编号、结束编号为例,例如每个编号占用10bit。在相关技术中,当丢失的数据包为4个时,则需要占用40bit,而图4的相关描述中只需要占用20比特,大大减少了需要状态报告的信令数。
S302、发送端向接收端发送状态报告。
S303、接收端根据状态报告,确定丢失的数据包。
S304、接收端将丢失的数据包重传至发送端。
发送端在获取到状态报告之后,向接收端发送该状态报告。接收端根据该状态报告,确定丢失的数据包。
请继续参照图4,由于E1的取值为1,E2、E3、E4的取值为0,则接收端确定E1所代表的格式指示位用于指示丢包指示信息的格式为E1所指示的格式。接收端在获取到丢包指示信息F1之后,根据该E1所指示的丢包指示信息的格式,可以获取丢包指示信息F1的内容,例如,该格式的丢包指示信息包括丢失数据包的起始编号和丢失数据包的结束编号,起始编号、结束编号均占10bit,则接收端可以根据前10比特获取丢失数据包的起始编号,根据后10比特获取丢失数据包的结束编号,从而获取丢失的数据包的编号,以确定丢失的数据包。
请继续参照图4,接收端在获取到丢包指示信息F1之后,由于E2的取值为1,E1、E3、E4的取值为0,则接收端确定E2所代表的格式指示位用于指示丢包指示信息的格式为E2所指示的格式。接收端在获取到丢包指示信息F2之后,根据该E2所指示的丢包指示信息的格式,可以获取丢包指示信息F2的内容。例如,该格式的丢包指示信息包括丢失数据包的起始编号和丢失数据包的数量,起始编号占用10bit,丢失数据包的数量占用10bit,则接收端可以根据前10bit获取起始编号,根据后10bit获取丢失数据包的数量,从而获取丢失的数据包的编号,以确定丢失的数据包。
接收端在确定丢失的数据包之后,将丢失的数据包重传至发送端,从而保证发送端可以获取到所需数据。
本公开的一些实施例提供的状态报告的上报方法,通过发送端获取状态报告,状态报告中包括至少一个用于指示丢包指示信息的格式的格式指示位,以及格式指示位所指示的格式对应的丢包指示信息,丢包指示信息用于指示至少两个丢失的数据包,该丢包指示信息不需要指出每个丢失的数据包的编号,就可以指示至少两个丢失的数据包,减少了状态报告中的上报比特数,节省了控制信令的开销,发送端向接收端发送状态报告,接收端根据状态报告,确定丢失的数据包,接收端将丢失的数据包重传至发送端,保证了数据传输的正确性。
下面结合上述图3所示的实施例,对发送端获取状态报告的实现方式进 行说明。
具体地,发送端根据预先配置的至少一个丢包指示信息的格式,生成状态报告。其中,上述的格式指示位所指示的格式为预先配置的至少一个丢包指示信息的格式中的一个或多个。
在一种可能的实现方式中,该预先配置的至少一个丢包指示信息的格式,可以为协议预先约定发送端和接收端可以识别的格式。发送端可以在协议约定的至少一个丢包指示信息的格式中,选择一个丢包指示信息的格式,然后将该格式对应的格式指示位的取值设置为预设值,从而生成状态报告。例如,协议预先预定发送端和接收端可以识别的格式有10种,发送端在该10种格式中选择至少一种格式生成状态报告。
在另一种可能的实现方式中,当该发送端为终端,接收端为网络侧设备时,该预先配置的至少一个丢包指示信息的格式,可以为网络侧设备配置给终端的,具体可参见图5所示。
图5为本公开的一些实施例提供的状态报告的上报方法的信令流程图。如图5所示,该方法包括S501-S503。
S501、接收端在所有可用的丢包指示信息的格式中确定发送端的待发送的状态报告可用的至少一个丢包指示信息的格式。
S502、接收端向发送端发送配置信息,配置信息用于预先配置该至少一个丢包指示信息的格式。
S503、发送端根据预先配置的至少一个丢包指示信息的格式,生成状态报告。
终端(发送端)与网络侧设备(接收端)可以根据协议预先约定的所有可用的丢包指示信息的格式。网络侧设备在所有可用的丢包指示信息的格式中确定终端的待发送的状态报告可用的至少一个丢包指示信息的格式。例如,协议约定有10种格式,网络侧设备选择其中的5种格式。然后网络侧设备向终端发送配置信息,该配置信息用于预先配置该至少一种丢包指示信息的格式,即配置网络侧设备选中的5种格式。
发送端根据该预先配置的至少一个丢包指示信息的格式,即网络侧设备选中的5种格式,生成状态报告。
在上述两种可能的实现方式中,发送端在预先配置的至少一个丢包指示信息的格式中,选择至少一种格式的丢包指示信息,发送端可以每次都选择第一格式,也可以依次选择第一格式、第二格式等,本公开对发送端选择丢包指示信息的格式的实现方式不做特别限制。
本文此处给出一种具体的实现方式。图6为本公开的一些实施例提供的状态报告的上报方法的流程图。如图6所示,该方法包括S601-S602。
S601、发送端获取丢失的数据包的编号,并确定上报丢失的数据包的编号所采用不同的丢包指示信息的格式对应的状态报告的比特数。
S602、发送端根据比特数最小的状态报告所对应的丢包指示信息的格式,生成状态报告。
发送端获取丢失的数据包的编号。例如,丢失的数据包的编号为1、2、3、4、6、7、8、11、13。该需要上报的丢失的数据包的编号可以对应多种格式的丢包指示信息。
例如,第一种方式:E1对应的丢包指示信息,包括:起始编号1,结束编号4;E2对应的丢包指示信息,包括:起始编号6,丢失的数据包的数量3;E3对应的丢包指示信息,包括:起始编号的前一个编号10,比特图010,结束编号的后一个编号14。
第二种方式:E2对应的丢包指示信息,包括:起始编号1,丢失的数据包的数量4;E3对应的丢包指示信息,包括:起始编号6,比特图001101,结束编号13。
第三种方式,E3对应的丢包指示信息,包括:起始编号1、比特图00010001101,结束编号13。
第四种方式……等等。对于其它的可能的实现方式,本文此处不再穷举。
由于比特图、丢失数据包的数量以及编号占用的比特数的数量存在不同,因此,在指示同一丢失的多个数据包时,状态报告有多种实现方式,不同的实现方式,对应不同的比特数。发送端确定不同的状态报告的比特数。
为了节省信令开销,发送端根据比特数最小的状态报告所对应的丢包指示信息的格式,生成状态报告。
本公开中通过发送端获取丢失的数据包的编号,并确定上报丢失的数据 包的编号所采用不同的丢包指示信息的格式对应的状态报告的比特数,根据比特数最小的状态报告所对应的丢包指示信息的格式,生成状态报告,可以使状态报告中上报的比特数最少,从而更好的节省控制信令的开销。
