- the available indication information may occupy only 1 bit, and is used to notify the network side that the terminal stores the reporting information of the related access failure or successful access, or distinguishes between the reporting information of successful access and the reporting information of access failure, respectively.
- the network side needs the reporting information of the access failure or successful access, it sends a downlink signaling request to the UE to report.
- the UE may carry all the related record content (that is, reporting information) of access failure or access success in the uplink information of the lower priority.
- the network side does not immediately request the UE to report, the UE keeps a record of the access failure / success for a period of time, which can be controlled by a timer. For example, if the network has not requested a report for more than 3 hours, the terminal itself deletes the saved report information of the access failure or successful access.
- SCGFailureReport signaling which is used by the UE to notify the network of the failed link information through the link that has not failed, so that the network quickly configures a new link for the UE. Data transmission continues.

相关申请的交叉引用

本公开涉及通信技术领域,特别涉及一种信息上报方法、信息获取方法、终端及网络设备。
由于双连接架构下,用户设备(User Equipment,UE,也称终端)在辅基站(Secondary Node,SN,也可以称作辅节点)也需要进行同步,所以也需要进行在SN的随机接入过程。
如果发生失败,协议中已有的辅服务小区群组(Secondary Cell Group,SCG)失败上报消息仅支持向网络侧上报失败的类型(随机接入失败,定时器超时,无线链路控制(Radio Link Control,RLC)达到最大重传次数,SCG更换失败等)以及各服务小区与邻小区的测量量,UE在SCG发生失败后立即向主基站(Master Node,MN,也可以称作主节点)上报该消息,其目的用于网络侧给UE迅速选择其他更好的SN节点以恢复SN连接及数据传输。
但是相关技术中,尚未有针对SN节点用于网络侧统计及调整参数的接入过程失败的具体记录与上报过程;如果接入成功,也没有针对SN节点的随机接入成功相关内容记录。

为使本公开的目的、技术方案和优点更加清楚,下面将结合附图及具体实施例对本公开进行详细描述。
下面对与本公开相关的背景技术进行介绍如下。
(1)随机接入流程
在小区搜索过程之后,UE已经与小区取得了下行同步,因此UE能够接收下行数据。但UE只有与小区取得上行同步,才能进行上行传输。UE通过随机接入过程(Random Access Procedure)与小区建立连接并取得上行同步。
随机接入过程有2种不同的方式:
1.基于竞争(Contention Based Random Access,CBRA),如图1所示,其主要流程为:
消息一(Msg1):UE选择随机接入前导码(preamble)和物理随机接入信道(Physical Random Access Channel,PRACH)资源并利用该PRACH资源向基站发送所选的随机接入preamble;
消息二(Msg2):随机接入响应(Random Access Response,RAR)消息,随机接入回复监听,UE在窗口内监听物理下行控制信道(Physical Downlink Control CHannel,PDCCH),以接收对应的随机接入回复;
消息三(Msg3):UE在Msg2指定的上行授权(UL grant)上发送上行传输。针对不同的场景可以有不同的信令内容,例如,无线资源控制(RRC)重建请求/RRC建立请求/系统信息请求等;
消息四(Msg4):竞争解决消息,UE根据Msg4可以判断随机接入是否成功。
2.基于非竞争(Contention-Free Random Access,CFRA),如图2所示,其主要流程为:
Msg0:随机接入的专用preamble与专用资源分配(RRC重配置消息);
Msg1:UE根据自身的测量结果(同步信号块(Synchronization Signal Block,SSB)/信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)Index等)与选择准则,选择合适的随机接入preamble和PRACH资源并利用该PRACH资源向基站发送所选的随机接入preamble;
Msg2:随机接入回复监听,UE在窗口内监听PDCCH,以接收对应的随机接入回复。
(2)NR测量用参考信号
NR测量用参考信号分为SSB与CSI-RS。
(3)专用/公共随机接入
切换命令至少包含目标小区的小区标识以及与波束(beam)配置相关的RACH配置。
UE在目标小区所有beam中选择一个suitable beam。
如果没有为UE所选的beam提供CFBA资源,则UE在选择的beam上执行CBRA。
目标小区的Beam的公共RACH配置仅与SSB相关联。网络可以在一个小区内有与SSB或者CSI-RS相关的专用RACH配置(SSB/CSI-RS ID,专用RACH资源,专用preamble等)。目标小区为了使得UE接入,可以在RRC重配置命令中包含以下的一种RACH配置:
公共RACH配置;
公共RACH配置和与SSB关联的专用RACH配置;
公共RACH配置和与CSI-RS关联的专用RACH配置;
在NR-SS或者CSI-RS上进行测量得到的测量结果如果高于门限,则与其相关联的专用RACH资源的优先级较高。即如果有配置的专用RACH资源对应的SSB/CSI-RS的测量结果超过设定门限,则直接使用专用资源进行CFRA,UE将不使用公共RACH资源进行CBRA;NR-SS/CSI-RS门限、相关资源、相关preamble可在切换命令中配置。
(4)双连接架构
双连接架构中,UE可能有一个MN,以及一至多个SN。MN与SN均可以为LTE/e-LTE/NR节点。当网络决定给UE添加/更换一个SN或者针对SN修改SCG无线资源配置时,如果需要使用SN的资源,则需要发起针对SN的随机接入过程。
以下以SN添加过程为例:
步骤1~2:MN向SN发送SN添加请求,及相关回复消息;
步骤3~5:MN向UE发送RRC重配置消息,UE给MN的相关回复消息,以及MN给SN的相关重配置完成消息。RRC重配置消息中携带SN相关的配置参数,如果包含了SCG无线资源配置,则执行步骤6;
步骤6:如果配置了需要使用SCG无线资源的承载,UE需要与SN的主辅服务小区(Primary Secondary Cell,PSCell)进行同步,即向网络发起随机接入。
步骤7~12:MN与SN以及核心网节点间的状态传递,数据前传以及路径转换等流程。
步骤6中UE向SN发起随机接入,可以基于步骤3中RRC重配置消息中分配的与beam相关的专用RACH资源与preamble(可能与SSB或者CSI-RS相关联)发起非竞争的随机接入,或者使用RRC重配置消息中给出的公共RACH资源并选择一个可用的preamble发起基于竞争的随机接入。
该步骤6中的内容也可以用于:
SN的更换,或者
SN内部调整SCG无线资源(SN修改)。
这两个流程可能由MN发起,或者由SN发起。
(5)上行链路(Uplink,UL)与辅助上行链路(Supplementary Uplink, SUL)
由于NR系统所使用的频点较高,可能导致覆盖范围变小。为了补充这种覆盖,网络可以给UE的上行配置UL与SUL两套参数。对于频分双工(FDD)或时分双工(TDD),都可以给UE配置额外的SUL以保障覆盖。其中SUL的覆盖范围大于UL的覆盖范围。
当UE在UL载波的下行测量质量低于网络广播门限时,使用SUL载波以及相关配置进行随机接入。一旦开始,本次随机接入的所有上行传输只能在该选定的SUL频点上发送。
(6)带宽分片(Bandwidth Part,BWP)
在自适应带宽(Bandwidth Adaption,BA)技术下,UE的接收和发送带宽不需要和小区的带宽一样大,同时也被设置成可配。一个小区所有带宽中的子集被称为BWP。
UE初始接入小区的BWP为initial BWP,为空闲态UE与连接态UE共同可见,initial BWP一般情况下带宽较窄。UE进入连接态后,网络可以为UE分配其他上下行BWP,仅连接态UE可用。UE接收同步重配消息后发起随机接入的BWP为上行firstActiveBWP。
本公开针对相关技术中没有针对SN的随机接入成功和/或失败的内容记录与上报,无法保证网络通信可靠性的问题,提供一种信息上报方法、信息获取方法、终端及网络设备。
如图4所示,本公开一实施例的信息上报方法,应用于终端,包括:
步骤41,在终端与辅节点的随机接入过程中,记录针对所述辅节点的目标接入状态的上报信息;
需要说明的是,该目标接入状态为接入成功或接入失败。
步骤42,将所述上报信息发送给网络设备;
需要说明的是,所述上报信息包括:波束相关信息、资源相关信息、小区相关信息、终端的位置信息和时间相关信息中的至少一项。
下面对上报信息中所包含的具体内容进行说明如下。
一、波束相关信息
需要说明的是,该波束相关信息包括以下信息中的至少一项:
A11、第一波束信息;
需要说明的是,当所述目标接入状态为接入失败时,所述第一波束信息为终端发生失败的波束信息,这里所提到的波束信息具体为波束的标识信息,例如,波束的索引。
A12、第一小区的波束的测量信息;
需要说明的是,所述第一小区包括:所述辅节点下终端发起随机接入的小区;进一步的,所述第一小区还包括:所述辅节点下终端发起随机接入的小区的邻小区。
需要说明的是,NR系统引入了波束(beam)级的信息,使用SSB与CSI-RS作为测量参考符号。
在SN添加过程,SN改变过程或者SN修改过程中,终端可以通过随机接入发起向SN的接入要求或响应网络的重配置要求。如果发生了接入失败,则终端可以记录如下内容:
A1、终端发生失败时的波束信息,以及针对该波束的测量结果;
A2、终端在失败前记录的发生失败的SN目标小区测量结果,包括RSRP与RSRQ(RSRQ取值与type有关),以及相关的波束级测量结果,包括基于SSB以及CSI-RS的测量结果;
A3、终端在失败前的各服务小区测量结果,包括RSRP与RSRQ(RSRQ取值与type有关),以及可能的波束级测量结果,包括基于SSB以及CSI-RS的测量结果;
A4、测量的各邻区结果,包括各接入网制式(RAT);
进一步地,相关网络侧接收到与接入失败有关的波束级的测量结果之后,可以用于与波束相关的配置参数的调整,例如,与波束相关联的前导码(preamble)与RACH资源配置等;或者上报给数据收集节点(TCE),用于运营商进行大数据统计等用途。
二、资源相关信息
需要说明的是,所述资源相关信息包括以下信息中的至少一项:
B11、终端使用的前导码和随机接入信道RACH资源信息;
B12、前导码发送次数;
B13、是否达到前导码的最大发送功率的指示信息;
B14、是否发生竞争的指示信息。
需要说明的是,相关网络侧接收到测量结果记录之后,可以用于与RACH相关的配置参数的调整,例如前导码分配、RACH资源配置等。
网络可以通过如下方式的其中一种给终端配置随机接入参数:
B1、公共RACH配置;
B2、公共RACH配置和与SSB关联的专用RACH配置;
B3、公共RACH配置和与CSI-RS关联的专用RACH配置;
如果网络给终端配置了公共与专用两种RACH配置信息,终端需要基于自身的波束级测量结果与网络配置的参考门限,自行判断使用公共RACH进行CBRA,还是使用与某个SSB/CSI-RS关联的专用RACH配置进行CFRA,因此需要UE上报实际使用的RACH相关参数,包括CFRA/CBRA,使用的前导码及发送次数,是否达到最大发送功率以及实际所使用的RACH资源信息等。
相关网络侧接收到与接入失败或接入成功有关的实际使用的前导码及RACH资源信息之后,可以用于改善RACH资源配置方案,例如,改变给终端配置的使用专用RACH资源的参考门限取值等;或者上报给TCE,用于运营商进行大数据统计等用途。
还需要说明的是,在所述目标接入状态为接入失败时,所述资源相关信息包括以下信息中的至少一项:
B21、发生接入失败的载波信息;
需要说明的是,该载波信息可以为终端使用的是UL载波,或终端使用的是SUL载波。具体地,网络通知终端进行随机接入所使用的同步重配消息中,会通知要求终端接入后使用UL或者SUL。如果发生接入失败后终端没有记录与上报,则网络侧可能会给UE发送其他配置信息而删除导致失败的配置信息。因此终端记录发生接入失败时的载波信息,有助于后续网络侧接收后判断失败原因并进行参数调整。
B22、终端使用的随机接入优先级相关信息;
具体地,该随机接入优先级相关信息包括:功率提升步长信息和/或回退 指示信息。
该功率提升步长信息(powerRampingStepHighPriority)指针对不同优先级随机接入具有一个发送前导码的功率提升步长;该回退指示信息(scalingFactorBI)指针对不同优先级随机接入具有一个回退指示,该回退指示的具体内容为回退所使用的缩放因子。
B23、发生接入失败的第一个激活的带宽分片。
需要说明的是,网络通知终端进行随机接入所使用的同步重配消息中,会通知要求UE接入后所使用的第一个激活的BWP(firstActiveBWP),该BWP可能为与初始(initial)BWP不重叠的其他BWP。如果发生接入失败后终端没有记录与上报,则网络侧可能会给终端发送其他配置信息而删除该导致失败的配置信息。因此终端记录发生接入失败时的firstActiveBWP,有助于后续网络侧接收后判断失败原因并进行参数调整。
相关网络侧接收到与接入失败有关的载波/BWP记录之后,可以用于改善同步重配的配置参数,例如,上报给数据收集节点(TCE),用于运营商进行大数据统计等用途。
除了上述载波/BWP信息,如果终端记录与上报不在接入失败后立即进行,则更多参数可能需要终端自行记录,在后续过程中再上报给网络。比如,随机接入所使用的随机接入优先级相关信息等,这些均有助于网络判断接入失败的原因,并指导后续配置或资源分配调整。
三、小区相关信息
需要说明的是,在所述目标接入状态为接入失败时,该小区相关信息包括以下信息中的至少一项:
C1、发生接入失败的小区的标识信息;
C2、发生接入失败的注册公共陆地移动网络(PLMN);
C3、在接入失败前对服务小区的测量结果;
C4、在接入失败前对除服务小区外的其他小区的测量结果。
四、终端的位置信息
需要说明的是,终端的位置信息指的是终端的地理位置信息,例如,下行到达时间观测差(Observed Time Difference Of Arrival,OTDOA)定位结果, 水平垂直定位结果,或者全球导航卫星系统(Global Navigation Satellite System,GNSS)定位结果等,用于发生失败的节点调整与位置信息有关的参数,比如SSB数量,天线位置/天线倾角,发送功率,或者用于数据收集节点/运营商大数据统计需要等。
五、时间相关信息
需要说明的是,该时间相关信息主要是在目标接入状态为接入失败时才会记录的内容,该时间相关信息包括:发生接入失败的时刻与失败上报时刻之间的时间间隔,该时间相关信息主要用于辅助接收节点寻找失败节点,判断数据有效性等。
进一步需要说明的是,上报信息的一种发送方式为:
发送上行信息给网络设备,所述上行信息指示所述终端存在上报信息的记录;
在接收到网络设备的上报请求后,将所述上报信息发送给网络设备。
需要说明的是,由于终端记录的信息量巨大,而SCGFailureReport仅需要上报针对SN连接失败后有助于网络侧快速给终端建立新的SN连接的信息,因此SN接入失败或接入成功的上报信息可以在终端进行保存,并在保存之后给网络侧上报可用指示信息。由于当前为针对SN的记录,终端在MN仍然保持连接,因此,可以直接在MN的所有下一条可用上行RRC消息中携带可用指示,或者,在任一更换小区/连接建立或恢复/重建等过程中携带可用指示,或者,针对接入成功的情况,向SN发送可用指示。该可用指示信息可能仅占用1bit,用于通知网络侧在终端保存了相关接入失败或接入成功的上报信息,或者区分接入成功的上报信息和接入失败的上报信息分别指示。当网络侧需要该接入失败或接入成功的上报信息时,给UE发送下行信令要求上报。UE可以在较低优先级的上行信息中携带所有接入失败或接入成功的相关记录内容(即上报信息)。
如果终端上报了可用指示信息后,网络侧没有马上要求UE上报,则UE保留该接入失败/成功记录一段时间,可以通过定时器进行控制。例如,超过3小时网络还没有要求上报,则终端自行删除保存的该接入失败或接入成功的上报信息。
进一步还需要说明的是,当所述目标接入状态为接入失败时,上报信息的另一种发送方式为:
发送携带所述上报信息的辅服务小区群组SCG失败信息给网络设备。
需要说明的是,在SCG发生失败的情况下,协议已经引入了SCGFailureReport信令,用于UE通过没有失败的链路通知网络发生失败的链路信息,以使得网络迅速给UE配置新的链路继续数据发送。因此,一种可能的上报方式为:UE所记录的针对SN的接入失败的上报信息,可以通过该SCGFailureReport信令通知给MN网络侧或者未发生失败的其他SN网络侧。
这里需要注意的是,当终端接入成功时,表明其与辅节点建立连接,此时,上报信息可以直接发送给辅节点,也可以发送给主节点,即上述的网络设备指的是辅节点和/或主节点;而当终端接入失败时,表明其未与辅节点建立连接,此时,终端只能与主节点进行通信,因此,在此种情况下,上述的网络设备指的是主节点。
由于上报信息为终端针对接入节点B的接入失败或接入成功情况的记录,因此接收终端记录的网络侧的节点A,可能不是发生接入失败或接入成功的节点B。针对此种情况,后续有两种处理方式:
方式一:如果设置的针对接入失败或接入成功的终端记录信息无法用于基站侧配置/资源调整,则接收网络侧的节点A无需解析该终端记录内容,由接收节点A直接上报给TCE,用于运营商进行大数据统计与运营商决策判断;
方式二:如果设置的针对接入失败或接入成功的终端记录信息可以被终端发生失败的节点B所利用,例如用于基站侧配置参数的调整,资源调度的调整,beam信息的调整等,则可由节点A初步解析出上报信息中指示的终端发生问题的网络侧的节点B,并将记录内容发送给UE发生过接入失败或接入成功的节点B。节点B可以使用记录内容进行基站相关的优化,和/或上报给TCE用于运营商进行大数据统计与运营商决策判断。
本公开实施例,通过在终端与辅节点的随机接入过程中,记录针对所述辅节点的目标接入状态的上报信息,将所述上报信息发送给网络设备,以此完善了5G及后续通信系统的通信流程,保证了网络通信的可靠性。
