技术领域
本公开涉及移动通信技术领域,尤其涉及一种信息获取方法、处理方法、节点、网络侧设备及装置。
背景技术
如图1和图2所示,在集成接入回程(IAB)网络架构中,IAB节点(node)可以支持下一代无线接入网络(Next Generation Radio Access Network,NG-RAN)的无线中继。其中,中继节点(即IAB节点)支持通过新空口(NR)进行接入和回程。网络侧NR回程的终止节点是IAB宿主(IAB-donor),回程可以经过一跳或者多跳。其中,图1中AMF表示接入和移动性管理功能网元,UPF表示用户面功能网元,gNB表示5G基站,NG、Xn、NR Uu、F1分别表示接口。图2中,MME表示移动性管理实体,S-PGW表示与数据网关连接的接口,eNB表示4G基站,MeNB表示主4G基站,SgNB表示辅节点,S1、X2、S1-U、X2-C、LTE Uu分别表示接口。
如图3所示,IAB-node通过一跳或多跳的形式连接到IAB-donor组成一个有向无环图(directed acyclic graph,DAG)。其中,IAB-node分为两部分,分别是终端部分(即IAB-MT)和支持5G基站分布单元(gNB-DU)功能的部分(即IAB-DU),通过IAB-MT与其父节点相连,通过IAB-DU与其子节点相连。
然而如果某些IAB节点经常发生RLF,其可能并不适合属于其当前所处的路由线路上,从而使得通信效果较差。

其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
此外,本公开实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用的系统可以是全球移动通讯(global system of mobile communication,GSM)系统、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)系统、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、高级长期演进(long term evolution advanced,LTE-A)系统、通用移动系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)系统、5G新空口(New Radio,NR)系统等。这多种系统中均包括终端设备和网络设备。系统中还可以包括核心网部分,例如演进的分组系统(Evloved Packet System,EPS)、5G系统(5GS)等。
本公开实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,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等。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,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 Initiated 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。无线终端设备也可以称为系统、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)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。

为了便于理解本公开实施例提供的信息获取方法,首先对RLF进行如下介绍。
在NR系统中,发生RLF的原因有如下几种:
第一种:T310定时器超时;
第二种:T312定时器超时;
第三种:一定条件下媒体接入控制(Media Access Control,MAC)上报随机接入问题(包括波束失败恢复失败和随机接入问题);
第四种:一定条件下RLC上报针对信令(无线)承载(Signaling Radio Bearer,SRB)或者数据无线承载(Data Radio Bearer,DRB)达到最大重传次数;
第五种:一定条件下连续先听后说,(Listen Before Talk,LBT)失败;
第六种:对于5G集成接入回程移动终端(IAB-MT),从其父节点接收的回程无线链路失败(BH RLF)指示等。
其中,针对T310超时,如果UE的无线资源控制(Radio Resource Control,RRC)从底层连续接收到N(例如N310的取值)个失步指示"out-of-sync",则开启RLF定时器T310。
其中,如果在T310运行过程中RRC层连续接收到M(例如N311的取值)个同步指示"in-sync",则认为失步问题已经解决,停止T310定时器;如果无法在T310运行过程中连续接收到M(例如N311的取值)个"in-sync",最终将导致T310定时器超时,则认为无线链路无法维持,发生了无线链路失 败。后续根据具体条件,UE可能选择一个新的小区发起重建过程,或者进入空闲态。
针对T312超时,为无线链路失败在异构网络中的一种增强。如果T310已经启动,而这时UE评估组织好一个测量报告(即对目标小区的测量报告),则UE在发送测量报告的同时,启动定时器T312。T312的总长度为网络设定的UE从发送测量报告到应该接收切换命令的最大容许时间。如果T312超时,则UE可以不等T310超时而直接发生RLF。而如果T310由于满足条件中止,则T312也随之停止。
而IAB节点的MT具有与UE相同的功能,因此,IAB节点之间可能会发生RLF。
图4示出了本公开实施例提供的一种信息获取方法的流程示意图。该方法应用于第一节点。如图4所示,该信息获取方法可以包括以下步骤:
步骤401:在第二节点发生无线链路失败RLF的情况下,接收所述第二节点发送的与所述第二节点发生RLF相关的指示。
其中,所述第二节点为所述第一节点的父节点。可选的,所述第一节点和所述第二节点均为IAB节点。
另外,第二节点发生RFL是指第二节点与第二节点的父节点之间发生RLF。并且第二节点可能连接有一个或者多个父节点,因此,第二节点发生RLF的情况可能包括第二节点与一个第二节点的父节点之间发生RLF,或者第二节点与多个第二节点的父节点之间发生RLF。
此外,此处所述的第二节点可以为第一节点的一个或者多个父节点,所述的第一节点可以为第二节点的一个子节点或者多个子节点。
步402:获取所述指示的第一参数信息。
即在本公开实施例中,根据所述指示,获取用于优化拓扑结构的第一参数信息。
其中,所述拓扑结构包括所述第一节点和所述第二节点。
由上述步骤401至402可知,在本公开的实施例中,在第二节点发生RLF的情况下,第一节点会接收第二节点发送的与第二节点发生RLF相关的指示,从而触发第一节点根据该指示,获取用于优化包括第一节点和第二节点的拓扑结构的第一参数信息,其中,第二节点为第一节点的父节点。由此可见, 本公开的实施例中,一个节点的父节点发生RLF的情况下,该节点会接收到此父节点发送的此父节点发生RLF相关的指示,从而触发该节点根据该指示获取用于优化拓扑结构的第一参数信息,因此,本公开的实施例,实现了针对优化拓扑结构进行信息收集的机制,从而为拓扑结构的优化提供了依据,进而为提升拓扑结构的通信质量奠定了数据基础。
可选的,所述指示包括如下指示中的至少一种:
第一指示,所述第一指示用于指示所述第二节点发生RLF;
第二指示,所述第二指示用于指示所述第二节点发生RLF并正在尝试恢复无线链路;
第三指示,所述第三指示用于指示所述第二节点的无线链路恢复成功;
第四指示,所述第四指示用于指示所述第一节点执行RLF;
第五指示,所述第五指示用于指示所述第二节点的无线链路恢复失败。
其中,指示第一节点执行RLF,即为指示第一节点开始按照第一节点和第二节点之间发生RLF的处理流程执行。
由此可知,本公开的实施例中,第二节点发生RLF时,第二节点可能会向第二节点的一个或者多个子节点发送第一指示、第二指示、第三指示、第四指示、第五指示中的至少一种指示。
可选的,所述第一参数信息包括如第一至第九项中的至少一项:
第一项:接收到的每一种指示,以及接收到该指示的接收次数;
第二项:第一类计时器的时长,其中,用于确定所述时长的所述第一类计时器的计时参数是根据第一目标时刻确定的,所述第一目标时刻包括各种指示的接收时刻、所述第一节点连接至所述第二节点的时刻、所述第一节点将所述第一参数信息发送给网络侧设备的时刻、满足所述第一节点向所述网络侧设备发送所述第一参数信息的发送条件的时刻、所述第一节点发生RLF的时刻;
第三项:在第一预设时刻主小区的测量结果;
第四项:在所述第一预设时刻邻小区的测量结果;
第五项:所述第一节点的无线网络临时标识C-RNTI;
第六项:所述第二节点的小区标识;
第七项:发生RLF时的主小区标识;
第八项:所述第一节点重建的小区标识;
第九项:所述第一节点重连接的小区标识。
那么在接收到第二节点发送的指示后,根据接收到的指示,获取所述第一参数信息的过程包括:
对接收到的每一种指示进行统计,得到第一统计信息,
获取所述第一节点和所述第二节点相关的第一属性信息。
其中,所述第一统计信息包括如上所述第一参数信息中的第一项信息、第二项信息,所述第一属性信息包括如上所述第一参数信息中的第三至九项信息中的至少一项信息。
可选的,所述第一参数信息包括如下中的至少一项:
接收到的每一种指示;
接收到的每一种指示的接收次数;
第一类计时器的时长,其中,用于确定所述时长的所述第一类计时器的计时参数是根据第一目标时刻确定的,所述第一目标时刻包括各种指示的接收时刻、所述第一节点连接至所述第二节点的时刻、所述第一节点将所述第一参数信息发送给网络侧设备的时刻、满足所述第一节点向所述网络侧设备发送所述第一参数信息的发送条件的时刻、所述第一节点发生RLF的时刻;
在第一预设时刻主小区的测量结果;
在所述第一预设时刻邻小区的测量结果;
所述第一节点的无线网络临时标识C-RNTI;
所述第二节点的小区标识;
发生RLF时的主小区标识;
所述第一节点重建的小区标识;
所述第一节点重连接的小区标识。
其中,所述第一预设时刻包括如下的至少一种:
所述第一节点发生RLF的时刻;
满足所述第一节点向所述网络侧设备发送所述第一参数信息的发送条件的时刻;
所述第一节点将所述第一参数信息发送给所述网络侧设备的时刻。
即可以记录第一节点发生RLF时的主小区的测量结果和邻小区的测量结 果,也可以记录满足第一节点向网络侧设备发送第一参数信息的发送条件时,主小区的测量结果和邻小区的测量结果,也可以记录第一节点将第一参数信息发送给IAB donor时的主小区测量结果和邻小区测量结果。
其中,第一节点向网络侧设备发送第一参数信息的发送条件可以为如下中的其中一种:
预先设置的周期到达、第一节点接收到网络侧设备的请求信息、预先设置的第一定时器超时、一种指示的接收次数达到其门限值、两种指示的接收次数达到各指示对应的门限值、三种指示的接收次数达到各指示对应的门限值、四种指示的接收次数达到各指示对应的门限值、五种指示的接收次数达到各指示对应的门限值。
另外,上述所述的“发生RLF时的主小区标识”,就是第二节点的小区标识。此处所述的“发生RLF”是指第一节点发生RLF,即所述的“发生RLF时的主小区标识”,为“第一节点发生RLF时的主小区标识”。
另外,无论第一节点是否发生RLF,第一节点都可以记录第一参数信息包括的前述第一至第六项信息,而在第一节点发生RLF时,第一节点才会执行RRC重建和RRC重连接的过程,因此,在第一节点发生RLF时,第一节点才会记录第一参数信息包括的前述第七至第九项信息。
此外,所述小区标识可以是小区所在的公共陆地移动网标识(Public Land Mobile Network ID,PLMN ID)、小区标识(cell ID)和跟踪区编码(Tracking Area Code);或者小区的标识信息可以是:物理小区标识(phyCellID)和载波频点(carrierFreq)。其中,PLMN ID、cell ID和Tracking Area Code组合在一起可以唯一标识一个小区;phyCellID和carrierFreq组合在一起可以唯一标识一个小区。
由上述可知,本公开的实施例中,第一节点接收到第二节点发送的至少一种第二节点发生RLF的相关指示之后,第一节点可以对接收到的指示进行统计,即统计接收到的每一种指示、每一种指示的接收次数以及第一类计时器的时长,并收集在第一预设时刻主小区的测量结果和邻小区的测量结果、第一节点的C-RNTI、第二节点的小区标识。并且在第一节点也发生RLF的情况下,第一节点还可以收集第一节点发生RLF时的主小区标识、第一节点重建的小区标识和重连接的小区标识中的至少一种。
可选的,根据第一目标时刻确定的所述第一类计时器的计时参数包括如下至少一种:
若所述第一类计时器的计时参数中的起始计时时刻为所述第一节点连接至所述第二节点的时刻,或者为所述第一节点接收到第一个指示的时刻,则所述第一类计时器的计时参数中的结束计时时刻为所述第一节点将所述第一参数信息发送给所述网络侧设备的时刻,或者为满足所述第一节点向所述网络侧设备发送所述第一参数信息的发送条件的时刻,或者为所述第一节点发生RLF的时刻;
若所述第一类计时器的计时参数中的起始计时时刻为接收到所述第三指示之前最后一个所述第一指示或者所述第二指示的接收时刻,则所述第一类计时器的计时参数中的结束计时时刻为接收到所述第三指示的时刻;
若所述第一类计时器的计时参数中的起始计时时刻为接收到所述第五指示之前最后一个所述第一指示或者所述第二指示的接收时刻,则所述第一类计时器的计时参数中的结束计时时刻为接收到所述第五指示的时刻;
若所述第一类计时器的计时参数中的起始计时时刻为所述第一节点发生RLF的时刻或者为接收到第四指示的时刻,则所述第一类计时器的计时参数中的结束计时时刻为所述第一节点将所述第一参数信息发送给所述网络侧设备的时刻,或者为满足所述第一节点向所述网络侧设备发送所述第一参数信息的发送条件的时刻;
若所述第一类计时器的计时参数中的起始计时时刻为接收到所述第四指示前最后一个所述第一指示或者所述第二指示的接收时刻,则所述第一类计时器的计时参数中的结束计时时刻为接收到所述第四指示的时刻。
其中,计时参数中起始计时时刻和结束计时时刻的设置规则不同,所对应的计时器也不同。例如:根据上述记载的第一类计时器的计时参数中起始计时时刻和结束计时时刻的设置规则,可以将第一类计时器划分为如下的第一至第五计时器,即第一类计时器具体可以包括如下中的第一至第五计时器中的至少一种:
第一计时器,第一计时器的起始计时时刻为第一节点连接至第二节点的时刻,或者为第一节点接收到第一个指示的时刻,第一计时器的结束计时时刻为第一节点将第一参数信息发送给IAB宿主的时刻,或者为满足第一节点 向网络侧设备发送第一参数信息的发送条件的时刻,或者为第一节点发生RLF的时刻;
第二计时器,第二计时器的起始计时时刻为接收到第三指示之前最后一个第一指示或者第二指示的接收时刻,第二计时器的结束计时时刻为接收到第三指示的时刻;
第三计时器,第三计时器的起始计时时刻为接收到第五指示之前最后一个第一指示或者第二指示的接收时刻,第三计时器的结束计时时刻为接收到第五指示的时刻;
第四计时器,第四计时器的起始计时时刻为第一节点发生RLF的时刻,或者为接收到第四指示的时刻,第四计时器的结束计时时刻为第一节点将第一参数信息发送给IAB宿主的时刻,或者为满足第一节点向网络侧设备发送第一参数信息的发送条件的时刻;
第五计时器,第五计时器的起始计时时刻为接收到第四指示前最后一个第一指示或者第二指示的接收时刻,第五计时器的结束计时时刻为接收到第四指示的时刻。
此处需要说明的是,针对上述第二计时器,在第一节点接收到第一指示或第二指示时,其就会开启第二计时器,若后续再次接收到第一指示或者第二指示(也就是说在接收到两次第一指示或者第二指示之间没有接收到第三指示),则在后续每一次接收到第一指示或者第二指示时,第二计时器归零,重新启动计时,直到接收到第三指示时,停止第二计时器。因此,第二计时器的时长是第一节点接收到第三指示前最后一个第一指示或者第二指示的接收时刻,至第三指示的接收时刻的时长。
同理,针对上述第三计时器,在第一节点接收到第一指示或第二指示时,其就会开启第三计时器,若后续再次接收到第一指示或者第二指示,则在后续每一次接收到第一指示或者第二指示时,第三计时器归零,重新启动计时,直到接收到第五指示时,则停止第三计时器。因此,第三计时器的时长是第一节点接收到第五指示前最后一个第一指示或者第二指示的接收时刻,至第五指示的接收时刻的时长。
同理,针对上述第五计时器,在第一节点接收到第一指示或第二指示时,其就会开启第五计时器,若后续再次接收到第一指示或者第二指示,则在后 续每一次接收到第一指示或者第二指示时,第五计时器归零,重新启动计时,直到接收到第四指示时,则停止第五计时器。因此,第五计时器的时长是第一节点接收到第四指示前最后一个第一指示或者第二指示的接收时刻,至第四指示的接收时刻的时长。
由此可知,本公开的实施例中,第一节点接收到第二节点发送的各种指示之后,可以根据前述第一计时器至第五计时器的相应起始计时时刻和结束计时时刻确定相应的计时器的时长并存储。
可选的,所述方法还包括:
向网络侧设备发送所述第一参数信息,以使所述网络侧设备根据所述第一参数信息优化所述拓扑结构。
可选的,所述方法还包括:
向网络侧设备发送所述第一参数信息。
其中,第一节点将获取到的第一参数信息发送给网络侧设备,从而使得网络侧设备可以根据第一参数信息优化拓扑结构。
另外,所述优化拓扑结构包括调整所述拓扑结构中的路由线路,和/或修改拓扑结构中的节点的网络参数。
例如第二节点发生RLF之后,第一节点获取的第一参数信息指示第二节点在某个路由线路上发生RLF的次数比较频繁,则网络侧设备可以将第二节点调整至其他路由线路上,或者修改第二节点与其发生RLF的父节点的网络参数,从而实现对拓扑结构的优化,进而提升通信质量。
此外,在所述第一节点和所述第二节点均为IAB节点时,所述网络侧设备可以为IAB宿主(donor)。
可选的,所述方法还包括:
若所述指示中包括预设指示,且所述第一节点发生RLF,则将失败原因指示发送给网络侧设备;
其中,所述失败原因指示用于指示所述第一节点发生RLF的原因为接收到所述预设指示,或者为所述第二节点发生RLF;
所述预设指示包括所述第一指示、所述第二指示、所述第四指示、所述第五指示中的至少一种。
其中,在第一节点接收到第二节点发送的第一指示、第二指示、第四指 示、第五指示中的至少一种,且第一节点发生RLF的情况下,第一节点发生RLF的原因很大概率是由于第二节点发生RLF导致的,因此,此种情况下,第一节点可以向网络侧设备发送上述失败原因指示信息。
另外,上述失败原因指示信息还可以和第一参数信息一起发送给网络侧设备,也可以单独发送给网络侧设备。例如,第一参数信息和失败原因指示信息中的至少一者可以添加至RLF报告中,从而在将RLF报告发送给网络侧设备。
可选的,所述向网络侧设备发送所述第一参数信息,包括:
每隔第一预设时间间隔,将获取的所述第一参数信息发送给所述网络侧设备;
或者
在接收到所述网络侧设备发送的请求信息时,将获取的所述第一参数信息发送给所述网络侧设备;
或者
在预先设置的第一定时器超时时,将获取的所述第一参数信息发送给所述网络侧设备;
或者
对于接收到所述指示,若其中N种指示的发送次数分别达到该N种指示的门限值时,将获取的所述第一参数信息发送给所述网络侧设备,其中,M为指示的种类数量,N为1至M中的其中一个整数。
其中,所述N种指示中各个指示的门限值可以相同也可以不同。
由此可知,在预先设置的周期到达时,或者在第一节点接收到网络侧设备的请求信息时,或者在预先设置的第一定时器超时,或者在N种指示的发送次数分别达到N种指示的门限值时,第一节点可以将其累计获取到的第一参数信息发送给网络侧设备。
由上述可知,本公开的实施例中,当一个IAB节点的父节点发生RLF,并通知其子节点连接失败的相关指示后,该IAB节点可以进行统计接收的指示并收集相关信息,即获取用于优化IAB节点构成的拓扑结构的第一参数信息,从而可以在后续将第一参数信息上报给IAB donor,由IAB donor调整IAB节点构成的拓扑结构的路由线路或者对拓扑结构中的节点的网络参数进行优 化。
图5示出了本公开实施例提供的一种信息获取方法的流程示意图。该方法应用于第二节点。如图5所示,该信息获取方法可以包括以下步骤:
步骤501:在所述第二节点发生无线链路失败RLF的情况下,向至少一个第一节点发送与所述第二节点发生RLF相关的指示。
其中,所述第二节点为所述第一节点的父节点。可选的,所述第一节点和所述第二节点均为集成接入回程IAB节点。
另外,第二节点发生RFL是指第二节点与第二节点的父节点之间发生RLF。并且第二节点可能连接有一个或者多个父节点,因此,第二节点发生RLF的情况可能包括第二节点与一个第二节点的父节点之间发生RLF,或者第二节点与多个第二节点的父节点之间发生RLF。
此外,此处所述的第二节点可以为第一节点的一个或者多个父节点,所述的第一节点可以为第二节点的一个子节点或者多个子节点。
步骤502:获取所述指示的第二参数信息。
即在本公开实施例中,根据所述指示,获取用于优化拓扑结构的第二参数信息。
其中,所述拓扑结构包括所述第一节点和所述第二节点。
由上述步骤501至502可知,在本公开的实施例中,在第二节点发生RLF的情况下,向第一节点发送与第二节点发生RLF相关的指示,同时,第二节点将根据发送给第一节点的指示,获取用于优化包括第一节点和第二节点的拓扑结构的第二参数信息,其中,第二节点为第一节点的父节点。由此可见,本公开的实施例中,一个父节点发生RLF的情况下,在向该父节点的子节点发送与该父节点发生RLF相关的指示之外,还将根据所发送的指示获取用于优化拓扑结构的第二参数信息。
因此,本公开的实施例,不仅提供了子节点针对优化拓扑结构进行信息收集的机制,还提供了父节点针对优化拓扑结构进行信息收集的机制,这样为拓扑结构的优化提供了依据,进而为提升拓扑结构的通信质量奠定了数据基础。
可选的,所述指示包括如下指示中的至少一种:
第一指示,所述第一指示用于指示所述第二节点发生RLF;
第二指示,所述第二指示用于指示所述第二节点发生RLF并正在尝试恢复无线链路;

第四指示,所述第四指示用于指示所述第一节点执行RLF;
第五指示,所述第五指示用于指示所述第二节点的无线链路恢复失败。
其中,指示第一节点执行RLF,即为指示第一节点开始按照第一节点与第二节点之间发生RLF的处理流程执行。
由此可知,本公开的实施例中,第二节点发生RLF时,第二节点可能会向第二节点的一个或者多个子节点发送第一指示、第二指示、第三指示、第四指示、第五指示中的至少一种指示。
可选的,所述第二参数信息包括如下第一项至第十项中的至少一项:

第六项:在所述第二预设时刻邻小区的测量结果;
第七项:所述第二节点的无线网络临时标识C-RNTI;
第八项:所述第二节点发生RLF时主小区的小区标识;
第九项:所述第二节点重建的小区标识;
第十项:所述第二节点重连接的小区标识。
由此可知,获取所述第二参数信息的过程包括:
对发送的每一种指示进行统计,得到第二统计信息,
获取所述第一节点和所述第二节点相关的第二属性信息。
其中,所述第二统计信息包括如上中的第一至四项信息,所述第二属性信息包括如上中的第五至十项信息。
其中,针对上述所述的第二参数信息可以包括的第一至第二项信息,可以采用不同的方式进行表示,例如下述所述的方式一或者方式二:

方式二:采用“哪个节点接收哪些指示分别接收了几次”的方式进行标识,如:第一节点接收到第一指示3次,接收到第二指示1次;第四节点接收到第一指示2次,接收到第二指示3次。
针对上述“每一种指示关联的节点的小区标识”,例如第五节点、第六节点都是第二节点的父节点,但是只是第五节点与第二节点之间发生了RLF,,那么RLF所属节点这里是指第五节点和第二节点。则第二节点会向其子节点中的至少部分节点发送指示,这些指示关联的节点的小区标识即为第五节点的小区标识。
可选的,所述第二参数信息包括如下中的至少一项:
发送的每一种指示;
发送的每一种指示的发送次数;

此外,所述小区标识可以是小区所在的PLMN ID、cell ID和Tracking Area Code;或者小区的标识信息可以是:phyCellID和carrierFreq。其中,PLMN ID、cell ID和Tracking Area Code组合在一起可以唯一标识一个小区;phyCellID和carrierFreq组合在一起可以唯一标识一个小区。
由上述可知,本公开的实施例中,第二节点向第一节点发送至少一种第二节点发生RLF的相关指示之后,第二节点可以对发送的指示进行统计,即统计发送的每一种指示、发送的每一种指示的次数、接收指示的节点的小区标识以及第二类计时器的时长,并收集在第二预设时刻主小区的测量结果和邻小区的测量结果、第二节点的C-RNTI、第二节点发生RLF时的主小区标识、第二节点重建的小区标识和重连接的小区标识中的至少一种。
可选的,根据第二目标时刻确定的所述第二类计时器的计时参数包括如下至少一种:
若所述第二类计时器的计时参数中的起始计时时刻为所述第二节点连接至所述第三节点的时刻,或者为所述第二节点发送第一个指示的时刻,则所述第二类计时器的计时参数中的结束计时时刻为所述第二节点将所述第二参 数信息发送给所述网络侧设备的时刻,或者为满足所述第二节点向所述网络侧设备发送所述第二参数信息的发送条件的时刻,或者为所述第二节点发生RLF的时刻;
若所述第二类计时器的计时参数中的起始计时时刻为发送所述第三指示之前最后一个所述第一指示或者所述第二指示的发送时刻,则所述第二类计时器的计时参数中的结束计时时刻为发送所述第三指示的时刻;
若所述第二类计时器的计时参数中的起始计时时刻为发送所述第五指示之前最后一个所述第一指示或者所述第二指示的发送时刻,则所述第二类计时器的计时参数中的结束计时时刻为发送所述第五指示的时刻;
若所述第二类计时器的计时参数中的起始计时时刻为所述第二节点发生RLF的时刻,则所述第二类计时器的计时参数中的结束计时时刻为所述第二节点将所述第二参数信息发送给所述网络侧设备的时刻,或者为满足所述第二节点向所述网络侧设备发送所述第二参数信息的发送条件的时刻;
若所述第二类计时器的计时参数中的起始计时时刻为发送所述第四指示前最后一个所述第一指示或者所述第二指示的发送时刻,则所述第二类计时器的计时参数中的结束计时时刻为发送所述第四指示的时刻。
其中,根据第二类计时器的计时参数中起始计时时刻和结束计时时刻的上述规则,可以将第二类计时器划分为如下的第六至第十计时器,即第二类计时器具体可以包括如下中的第六至第十计时器中的至少一种:第六计时器,第六计时器的起始计时时刻为第二节点连接至第三节点的时刻,或者为第二节点发送第一个指示的时刻,第六计时器的结束计时时刻为第二节点将第二参数信息发送给网络侧设备的时刻,或者为满足第二节点向网络侧设备发送第二参数信息的发送条件的时刻,或者为第二节点发生RLF的时刻;
第七计时器,第七计时器的起始计时时刻为发送第三指示之前最后一个第一指示或者第二指示的发送时刻,第七计时器的结束计时时刻为发送第三指示的时刻;

此处需要说明的是,针对上述第七计时器,在第二节点发送第一指示或第二指示时,其就会开启第七计时器,若后续再次发送第一指示或者第二指示,则在后续每一次发送第一指示或者第二指示时,重新启动第七计时器,直到发送第三指示时,则停止第七计时器。因此,第七计时器的时长是第二节点发送第三指示前最后一个第一指示或者第二指示的发送时刻,至第三指示的发送时刻的时长。
同理,针对上述第八计时器,在第二节点发送第一指示或第二指示时,其就会开启第八计时器,若后续再次发送第一指示或者第二指示,则在后续每一次发送第一指示或者第二指示时,重新启动第八计时器,直到发送第五指示时,则停止第八计时器。因此,第八计时器的时长是第二节点发送第五指示前最后一个第一指示或者第二指示的发送时刻,至第五指示的发送时刻的时长。
同理,针对上述第十计时器,在第二节点发送第一指示或第二指示时,其就会开启第十计时器,若后续再次发送第一指示或者第二指示,则在后续每一次发送第一指示或者第二指示时,重新启动第十计时器,直到发送第四指示时,则停止第十计时器。因此,第十计时器的时长是第二节点发送第四指示前最后一个第一指示或者第二指示的发送时刻,至第四指示的发送时刻的时长。
由此可知,本公开的实施例中,第二节点向第一节点发送各种指示之后,可以根据前述第六计时器至第十计时器的相应起始计时时刻和结束计时时刻记录相应的计时器的时长。

另外,所述优化拓扑结构包括调整所述拓扑结构中的路由线路,和/或修改拓扑结构中的节点的网络参数。
例如第二节点发生RLF之后,第二节点获取的第二参数信息指示第二节点在某个路由线路上发生RLF的次数比较频繁,则网络侧设备可以将第二节点调整至其他路由线路上,或者修改第二节点与其发生RLF的父节点的网络参数,从而实现对拓扑结构的优化,进而提升通信质量。
此外,在所述第一节点和所述第二节点均为IAB节点时,所述网络侧设备可以为IAB宿主。

其中,第三参数信息可以和第二参数信息一起发送给网络侧设备,也可以单独发送给网络侧设备。例如,第三参数信息和第二参数信息中的至少一者可以添加至RLF报告中,从而在将RLF报告发送给网络侧设备。
由此可知,上述第二参数信息和第三参数信息中的至少一者可以添加至RLF报告中。
可选的,所述向网络侧设备发送所述第二参数信息,包括:
每隔第二预设时间间隔,将获取的所述第二参数信息发送给网络侧设备;
或者
在接收到所述网络侧设备发送的请求信息时,将获取的所述第二参数信息发送给所述网络侧设备;
或者
在预先设置的第二定时器超时时,将获取的所述第二参数信息发送给所述网络侧设备;

对于接收到所述指示,若其中K种指示的发送次数分别达到该K种指示的门限值时,将获取的所述第二参数信息发送给所述网络侧设备,其中,M为指示的种类数量,K为1至M中的其中一个整数。
其中,所述K种指示中各个指示的门限值可以相同也可以不同。
由此可知,在预先设置的周期到达时,或者在第二节点接收到网络侧设备的请求信息时,或者在预先设置的第二定时器超时,或者在K种指示的发送次数分别达到K种指示的门限值时,第二节点可以将其累计获取到的第二参数信息发送给网络侧设备。
由上述可知,本公开的实施例中,当一个IAB节点的父节点发生RLF,并通知其子节点连接失败的相关指示后,该IAB节点的父节点可以进行统计接收的指示并收集相关信息,即获取用于优化IAB节点构成的拓扑结构的第二参数信息,从而可以在后续将第二参数信息上报给IAB donor,由IAB donor调整IAB节点构成的拓扑结构的路由线路或者对拓扑结构中的节点的网络参数进行优化。
总之,在本公开实施例中,一个IAB节点的父节点发生RLF的情况下,该IAB节点会接收到此父节点发送的此父节点发生RLF相关的指示,从而触发该IAB节点和该IAB节点的父节点中的至少一者,获取用于优化IAB节点构成的拓扑结构的参数信息,因此,本公开的实施例,实现了针对优化IAB节点构成的拓扑结构进行信息收集的机制。

步骤602:根据所述参数信息优化所述拓扑结构。
其中,所述优化拓扑结构包括调整所述拓扑结构中的路由线路,和/或修改拓扑结构中的节点的网络参数。
