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。
LTE系统针对初始建立失败,记录与上报的内容包括:
A1、发生失败的小区的全球小区识别码(Cell Global Identifier,CGI);
A2、位置信息(Location),包括位置坐标(locationCoordinates),以及水平速度(horizontalVelocity)(如果可用);
A3、失败小区的测量结果,包括参考信号接收功率(Reference Signal Receiving Power,RSRP)与参考信号接收质量(Reference Signal Receiving Quality,RSRQ)(RSRQ取值与type);
A4、测量的邻区结果,包括各RAT;
A5、preamble发送次数;
A6、是否竞争;
A7、是否达到最大发送功率;
A8、发生失败与失败上报之间的时间间隔;
LTE中针对初始建立的RACH失败的上报方式为:如果发生初始建立失败,则收集相关信息放入变量,在适当的上行消息中通知connEstFailInfoAvailable指示给网络。
(1)随机接入流程
在小区搜索过程之后,用户设备(User Equipment,UE,也称终端)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)UE连接建立与连接恢复过程
UE连接建立与连接恢复均使用基于竞争的随机接入过程,在UE发送preamble(msg1)并接收到RAR消息(msg2)之后,第一条RRC上行消息为随机接入过程的msg3,第一条RRC下行消息为随机接入过程的msg4,第二条RRC上行消息为随机接入过程的msg5。
空闲(IDLE)态UE可以发起RRC连接建立过程,由UE发送RRC建立请求(RRCSetupRequest)消息,网络如果同意UE接入则回复RRCSetup消息,之后UE发送RRC建立完成(RRCSetupComplete)消息,具体流程如图3所示。
非激活(INACTIVE)态UE可以发起RRC连接恢复过程,由UE发送RRC恢复请求(RRCResumeRequest)消息:
网络如果成功从锚点小区(anchor cell)获得了UE的上下文并同意UE 接入则回复RRC恢复(RRCResume)消息通知UE恢复连接,之后UE发送RRC恢复完成(RRCResumeComplete)消息。具体流程如图4所示。
网络如果未能成功从anchor cell获得UE的上下文,但仍同意UE接入则执行回退(fallback)过程回复RRCSetup消息通知UE建立一条新的连接,之后UE发送RRCSetupComplete消息。具体流程如图5所示。
(3)SSB
物理层规定的用于同步以及主信息块读取的信息块,每个波束(beam)对应一个SSB索引。
可以用于无线资源管理(Radio Resource Management,RRM)测量。
(4)UL与SUL
由于新空口(New radio,NR)系统所使用的频点较高,导致覆盖范围变小。为了补充这种覆盖,网络可以给UE的上行配置上行链路(Uplink,UL)与辅助上行链路(Supplementary Uplink,SUL)两套参数。其中SUL可以使用长期演进(Long Term Evolution,LTE)所在频段位置。
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。
(5)按需分配(on-demand)系统信息(System Information,SI)
NR系统的系统信息通过广播的方式发送给IDLE/INACTIVE态UE。但网络可能仅针对部分必要的系统信息一直发送广播,而其他系统信息如果没有UE请求,则不在广播中发送。
IDLE态或INACTIVE态UE可以通过随机接入的msg1或者msg3请求网络发送某个/某些SI message。如果通过基于msg3(msg3 based)的方式,则UE可以在单独的RRC上行专用信令中给出想要获取的SI message索引;如果通过基于msg1(msg1based)的方式,则网络侧需要预先在系统信息中广播针对系统信息SI请求所使用的配置信息,例如SI message索引与preamble的映射关系,可以使用的RACH资源,以及资源与SSB的对应关系等。
Msg1/msg3 based SI request在MAC层竞争解决成功后都需要通知RRC。
本公开针对相关的RRC接入过程中的RACH失败/成功时记录与上报的内容已经不满足5G及后续通信系统的需求,无法保证5G及后续通信系统的通信可靠性的问题,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6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61,获取终端针对目标过程的执行结果;
需要说明的是,该目标过程为连接建立过程、连接恢复过程或系统信息请求过程;对应的目标过程的执行结果为接入失败或接入成功;因针对上述的三种过程,终端均会执行接入过程,因此,针对这三种过程对应的执行结果指的便是随机接入的结果,即,接入成功或接入失败。
步骤62,将与所述执行结果相对应的上报信息发送给网络设备;
需要说明的是,该上报信息包括:目标过程的类别信息、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。
需要说明的是,该目标过程的类别信息用于进行连接建立过程、连接恢复过程和系统信息请求过程的区分。
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:
A1、第一波束信息;
需要说明的是,当所述执行结果为接入失败时,所述第一波束信息为终端发生失败的波束信息;当所述执行结果为接入成功时,所述第一波束信息为终端成功进行接入所使用的波束信息;还需要说明的是,该波束信息具体为波束的标识信息,例如,波束的索引。
A2、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:终端发起随机接入的小区;进一步地,所述第一小区还包括:终端发起随机接入的小区的邻小区。
具体地,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。其中SSB可以同时用于IDLE/INACTIVE与连接 (CONNECTED)态,使用SSB索引作为终端的波束级测量结果的标识。
终端在IDLE/INACTIVE进行基于SSB的移动性测量,将波束级的测量结果通过计算得到小区级的测量结果用于小区选择/重选移动性准则的输入参数,实现IDLE/INACTIVE的UE移动性。
例如,当终端需要建立连接或恢复连接时,如果发生了接入失败,则终端可以记录如下内容:
A11、终端针对小区发起接入但发生失败时所使用波束的波束信息,以及针对该波束的波束级测量结果;
A12、终端在失败前的IDLE/INACTIVE态针对驻留小区及各邻区的测量结果,包括RSRP与RSRQ(RSRQ取值与type有关),以及可能的波束级测量结果。
相关网络侧在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SSB数量、天线位置等;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,该资源相关信息包括以下信息中的至少一项:
B1、终端使用的前导码和随机接入信道RACH资源信息;
需要说明的是,该前导码指终端在进行随机接入时实际使用的前导码;该RACH资源信息指终端实际使用的RACH资源信息。
B2、终端使用的载波信息;
具体地,该载波信息指的是终端在进行随机接入时,实际使用的载波,可以为终端使用的是UL载波,或终端使用的是SUL载波。
B3、前导码发送次数;
B4、是否达到前导码的最大发送功率的指示信息;
B5、RACH资源信息与同步信号块(SSB)的对应关系。
例如,当终端需要建立连接或恢复连接时,如果发生了接入失败或接入成功,终端可以记录上述的B1-B5中的一种或多种信息。需要说明的是,网络系统信息中可以广播两套RACH参数,分别针对UL与SUL。终端想要与网络侧建立连接时,可以根据当前的测量结果,自行选择通过UL或者SUL 发起接入。当终端在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。如果发生接入失败,网络侧无法获知该接入失败行为是在哪个载波上发生的。因此终端需要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接入失败原因并进行参数调整。终端一旦在某载波上发起随机接入,则该次随机接入的所有上行传输只能在该选定的上行载波上发送。
除了上报载波信息,与RACH相关的其他的终端接入信息(前导码发送次数,是否达到前导码的最大发送功率的指示信息,RACH资源信息,RACH资源与SSB的对应关系等)均可以在UE进行记录并后续上报。
相关网络侧接收到测量结果记录之后,可以用于改善RACH资源配置方案,例如前导码分配、RACH资源配置等;或者上报给TCE,用于运营商进行大数据统计等用途。
三、小区相关信息
进一步需要说明的是,该小区相关信息包括以下信息中的至少一项:
C1、终端注册的公共陆地移动网络(PLMN);
C2、终端在第一状态针对当前驻留小区和当前驻留小区的邻区的测量结果信息;
其中,所述第一状态包括:空闲态和/或非激活态。
需要说明的是,当所述执行结果为接入失败时,所述测量结果信息为终端在接入失败前的第一状态针对当前驻留小区和当前驻留小区的邻区的测量结果信息;进一步,该测量结果信息可以为:终端在接入失败前的空闲态或非激活态,针对当前驻留小区和当前驻留小区的邻区进行的最近的一次测量(即,距接入失败的时刻最近的一次测量)所得到的测量结果。
具体地,当所述执行结果为接入失败时,所述小区相关信息包括:发生接入失败的小区的标识信息;当所述执行结果为接入成功时,所述小区相关信息包括:终端成功接入的小区的标识信息。
例如,当终端发生接入失败时,终端需要记录发生接入失败的小区标识(例如,小区Identity)和/或注册的PLMN,用于接收网络节点(即网络设备)解析后将失败记录内容发给发生失败的节点,以及确定接入失败时在失败的 网络节点所使用的PLMN。
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执行结果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,主要用于辅助接收节点寻找失败节点,判断数据有效性等。
还需要说明的是,当目标过程为系统信息请求过程时,所述上报信息还包括以下信息中的至少一项:
D1、随机接入类别信息;
需要说明的是,该随机接入类别信息指的是基于消息一(Msg1)的系统信息请求的随机接入还是基于消息三(Msg3)的系统信息请求的随机接入。
D2、系统信息的获取时延信息。
例如,在IDLE/INACTIVE态,终端除了可以为了建立连接发起随机接入之外,还可以通过发起随机接入请求系统信息。如果为基于消息一(msg1 based)的方式,则网络侧需要预先在系统信息中广播针对系统信息SI请求所使用的配置信息,例如SI message索引与前导码的映射关系,可以使用的RACH资源信息,以及RACH资源与SSB的对应关系等。
如果针对SI request触发随机接入请求后,未收到MAC层发来的成功指示,则终端可以认为该次SI请求失败或接入失败。失败的原因可能为msg1未发送成功,网络侧不同意该SI发送请求,或者终端接收消息二(msg2)未成功。为了区分这几种失败原因,并针对失败问题进行优化,终端可以记录相关RACH的发起是否针对SI request,及接入相关信息,例如,preamble发送次数,是否达到前导码的最大发送功率的指示信息,RACH资源信息, RACH资源与SSB的对应关系等。
如果针对SI request触发随机接入请求后,成功收到MAC层发来的指示,则UE可以认为该次SI请求成功或接入成功,后续在相应位置等待网络发送终端所需的SI message。为了优化系统信息获取算法方案等目的,针对整个SI获取过程,终端可以记录SI的获取时延信息等,例如,可以用于基站侧计算SI的获取平均时延,调整系统信息周期,按需分配(on-demand)方式等。
进一步需要说明的是,上述的上报信息中,NR系统中新增的信息包括:
D11、发生失败的波束信息或终端成功进行接入所使用的波束信息;
D12、终端发起随机接入的小区及终端发起随机接入的小区的邻小区的波束的测量信息;
D13、终端使用的前导码和RACH资源信息;
D14、RACH资源信息与同步信号块SSB的对应关系
D15、终端使用的载波信息;
D16、用于系统信息请求的参数信息,包括随机接入类别信息和系统信息的获取时延信息。
从LTE继承的信息包括:
D21、发生接入失败的小区的标识信息和/或注册的PLMN;
D22、终端在接入失败前的第一状态针对当前驻留小区和当前驻留小区的邻区的测量结果信息;
D23、前导码发送次数;
D24、是否达到前导码的最大发送功率的指示信息;
D25、终端的位置信息;
D26、发生接入失败的时刻与失败上报时刻之间的时间间隔;
在接入成功或接入失败时,终端会从D11-D16以及D21-D26中选择一项或多项组成上报信息,发送给网络设备。
还需要说明的是,针对接入成功的内容记录,终端在连接态可以直接上报给网络设备;而针对接入失败的内容记录,或者针对SI请求的内容记录(on-demand SI获取无需进入连接态),终端可以在连接建立/连接重建/连接恢复/切换等过程中给网络侧发送可用指示,在网络通知上报后再发送到网络 侧。由于该记录为终端针对接入节点B失败情况的记录,因此接收终端记录的上报信息的是网络侧的节点A,可能不是发生失败的网络侧的节点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/接入成功的终端记录信息无法用于基站侧进行配置或进行资源调整,则网络侧的节点A无需解析该终端上报信息,由节点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的上报信息可以被终端发生失败的网络侧的节点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,波束信息的调整等,则可由接收上报信息的节点A初步解析出上报信息中指示的终端发生接入问题的网络侧的节点B,并将记录内容发送给终端发生过接入失败的节点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,通过根据连接建立过程、连接恢复过程或系统信息请求过程的执行结果,进行上报信息的发送,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。
