Description

小区重选方法，参数发送方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
在第五代(5G)通信技术中，网络设备和终端设备之间可以进行业务发送。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
另外，5G还可以支持许多垂直行业中的用例(use case)，例如工业环境中的设备(例如工业网无线传感器)连接到5G无线接入和核心网中，智慧城市创新中的监控摄像头的数据传输以及可穿戴设备，包括智能手表、手环、健康相关的设备和医疗监控设备等。
上述用例的特点是，设备成本和复杂度比当前标准版本的高端eMBB和URLLC设备低，尤其是工业网无线传感器。此外对大多数用例的要求是，标准设计需要支持设备具有较小的尺寸，业务速率要求不高，以及特定用例中要求设备具有较长的电池寿命。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
目前，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)支持研究减少能力(Reduced Capability，RedCap)的终端设备(以下简称UE)的特性和参数，该RedCap UE可以涵盖上面三种用例中的终端设备，具有比当前标准版本中eMBB和URLLC更低端的能力。
发明人发现，由于这些减少能力的终端设备可能只支持1～2个收发天线和/或有 限的带宽等，如果部署支持大量RedCap UE的小区，会损失网络容量和性能，因此，为了避免损失网络容量和性能，小区需要限制RedCap UE的接入，目前还没有提出如何支持或限制RedCap UE重选到一个小区的相关方法。

第一方面的实施例
本申请实施例提供一种小区重选方法，从终端设备侧进行说明。
图3是本申请实施例的小区重选方法的一示意图，如图3所示，该方法包括：
301，该终端设备获取减少能力的终端设备或减少能力的终端设备的使用场景对应的第一小区重选参数；
302，该终端设备根据该第一小区重选参数进行小区重选。
值得注意的是，以上附图3仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其它的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图3的记载。
在一些实施例中，网络设备为减少能力的终端设备或减少能力的终端设备的使用场景配置其特定的小区重选参数，由此使得减少能力的终端设备优先重选到运营商期望的小区，例如用于服务减少能力的终端设备的小区，或者使得减少能力的终端设备尽量不重选到运营商不期望的小区，以防止大量减少能力的终端设备接入和连接而产生的拥塞，保持网络容量并对其它常规终端设备提供良好的服务。此外，操作简单且对现有常规终端设备的行为没有影响。
在一些实施例中，该第一小区重选参数是为减少能力的终端设备(RedCap UE)或减少能力的终端设备的使用场景(use case)配置的特定小区重选参数，该使用场景可以是减少能力的终端设备的使用场景(use case of RedCap UE)，例如，该使用场景可以是工业环境中的设备或监控摄像头或可穿戴设备等，本实施例并不以此作为限制，减少能力的终端设备也可以第一类型的减少能力的终端设备，例如该第一类型可以是频率范围一(Frequency Range 1，FR1)中的减少能力的终端设备类型，或频率范围二(Frequency Range 2，FR2)中的减少能力的终端设备类型，或高数据速率(例如50Mbps或100Mbps等数据速率)终端设备类型，或低数据速率(例如低于10Mbps等数据速率)终端设备类型，或高端终端设备类型(例如高端可穿戴设备等)，或低端终端设备类型(例如低端可穿戴设备或工业无线传感器等)等；减少能力的终端设备也可以是第一能力的减少能力的终端设备，例如该第一能力可以是具有高带宽能力，例如终端设备支持的带宽超过50MHz或超过100MHz，或具有较低带宽能力，例如终端设备支持的带宽为50MHz或更低，或者具有较高天线接收或发送能力，例如支持2个接收天线或支持2个发送天线，或者具有较低天线接收或发送能力，例如支持1个接收天线或1个发送天线，等等。以上仅示例说明，但本申请并不以此作为限制，例如，还可以不区分减少能力的终端的类型或能力，针对所有减少能力的终端设备统一配置特定的小区重选参数。
在一些实施例中，为上述不同类型或不同能力或不同使用场景配置的特定小区重选参数可以相同或不同，本申请实施例并不以此作为限制。
在一些实施例中，该第一小区重选参数包括以下参数中的至少一个：小区和/或频率的第一重选优先级的参数，第一白名单，第一黑名单，用于测量和评估小区的第一参数，第一速度相关参数。
在一些实施例中，该小区和/或频率的第一重选优先级是减少能力的终端设备(RedCap UE)或减少能力的终端设备在一个使用场景(use case)中在小区重选过程中应用的小区和/或频率的重选优先级，该第一重选优先级的参数可以用于指示小区和/或频率的绝对优先级。其中，该绝对优先级为优先级值，例如，该绝对优先级可以为优先级值0至7，其中，0表示最低优先级，7表示最高优先级，或者绝对优先级可以为优先级为高或中或低的等级。
在一些实施例中，该第一重选优先级的参数用于指示小区和/或频率的相对优先 级，该相对优先级为该第一重选优先级相对于第二重选优先级的倍数(该倍数可以为整数或小于1的小数等)，或者该第一重选优先级与第二重选优先级的差(该差值可以为正或负值)，其中，该第二重选优先级表示现有的网络设备配置的小区重选过程中使用的小区或频率的绝对优先级，例如该第二重选优先级可以是非RedCap UE(例如常规UE)在小区重选过程中应用的小区和/或频率的重选优先级，该第二重选优先级可以为优先级值0至7，其中，0表示最低优先级，7表示最高优先级，该相对优先级为一个系数，该系数可以是该第一重选优先级相对于第二重选优先级的倍数，或者该第一重选优先级与第二重选优先级的差。
在一些实施例中，小区和/或频率的第一黑名单是减少能力的终端设备(RedCap UE)或减少能力的终端设备的使用场景(use case)在小区重选过程中应用的小区和/或频率的黑名单，例如可以是在小区重选过程中测量小区和/或频率的黑名单，该终端设备不测量该黑名单中的小区和/或频率上的小区的质量；或者该黑名单是候选小区和/或频率的黑名单，该终端设备不将该黑名单中的小区和/或频率作为小区重选过程中的候选小区和/或候选频率；或者该黑名单是用于判定小区和/或频率优先级的黑名单，该终端设备将该黑名单中的小区和/或频率的重选优先级确定为小区重选过程中的最低优先级。
在一些实施例中，小区和/或频率的第一白名单是减少能力的终端设备(RedCap UE)或减少能力的终端设备的使用场景(use case)在小区重选过程中应用的小区和/或频率的白名单，例如可以是在小区重选过程中测量小区和/或频率的白名单，该终端设备测量该白名单中的小区和/或频率上的小区的质量或者该终端设备只测量该白名单中的小区和/或频率上的小区的质量；或者该白名单是候选小区和/或频率的白名单，该终端设备将该白名单中的小区和/或频率作为小区重选过程中的候选小区和/或候选频率或者该终端设备只将该白名单中的小区和/或频率作为小区重选过程中的候选小区和/或候选频率；或者该白名单是用于判定小区和/或频率优先级的白名单，该终端设备将该白名单中的小区和/或频率的重选优先级确定为小区重选过程中的最高优先级。
在一些实施例中，该用于测量和评估小区的第一参数是减少能力的终端设备(RedCap UE)或减少能力的终端设备的使用场景(use case)在小区重选过程中计算小区质量应用的参数，该第一参数可以包括以下参数的至少一种：SSB质量门限 absThreshSS-BlocksConsolidation(选择质量高于该门限的SSB以计算邻小区和服务小区的质量)，要做平均计算的SSB的个数nrofSS-BlocksToAverage(用于生成小区质量要平均的SSB的个数)，小区之间的偏移值Qoffset s,n，对相等优先级频率的频率特定的偏移值Qoffset frequency，排序标准(ranking criteria)的假设值Q hyst，同频测量的门限S IntraSearch，异频测量和异无线接入技术(inter-RAT)测量的门限S nonIntraSearch，小区重选定时器的值Treselection RAT，向比当前服务频率优先级高的RAT或频率重选所使用的门限Thresh X, High，向比当前服务频率优先级低的RAT或频率重选所使用的门限Thresh X,Low，向比当前服务频率优先级低的RAT或频率重选时UE在服务小区使用的门限Thresh Serving,Low。
例如，在小区重选过程中，可以根据上述第一参数(例如SSB质量门限，要做平均计算的SSB的个数等)计算小区质量Qmeas，在测量后需要进行重选评估，针对同频和相同优先级的异频，可以考虑根据上述用于测量和评估小区的第一参数(例如小区之间的偏移值，排序标准(ranking criteria)的假设等)计算如下R小区排序标准：
服务小区R s＝Q meas,s+Q hyst-Qoffset temp
邻小区R n＝Q meas,n-Qoffset-Qoffset temp。
其中，Qmeas表示测量结果，Qoffset temp表示连接失败时应用的临时小区偏移值。
例如，在小区重选过程中，可以将上述第一参数(例如同频测量的门限，异频测量和异无线接入技术(inter-RAT)测量的门限，向比当前服务频率优先级高的RAT或频率重选所使用的门限，向比当前服务频率优先级低的RAT或频率重选所使用的门限，向比当前服务频率优先级低的RAT或频率重选时UE在服务小区使用的门限)与其对应的小区质量进行比较，以确定重选的小区，具体请详见后述图4的说明。
在一些实施例中，该第一速度相关参数是减少能力的终端设备(RedCap UE)或减少能力的终端设备的使用场景(use case)在小区重选过程中应用的速度相关参数，该第一速度相关参数可以包括以下参数的至少一种：评估小区重选数量的持续时间T CRmax、进入中移动性状态的小区重选的最大个数N CR_M、进入高移动性状态的小区重选的最大个数N CR_H、进入正常移动性之前的额外时间段、高移动性状态中对Q hyst的缩放系数sf-High、中移动性状态中对Q hyst的缩放系数sf-Medium、高移动性状态中对小区重选定时器的缩放系数、中移动性状态中对小区重选定时器的缩放系数等。
例如，在小区重选过程中，在确定重选定时器(具体请详见后述图4的说明)长 度时，可以考虑该第一速度相关参数，例如移动性高的UE对应的重选定时器为T reselectionRAT乘以缩放系数sf-High，因此移动性高的UE对应的重选定时器较短，重选定时器较短则表示在小区重选时，该移动性高的UE更快重选到目标小区，防止丢失覆盖。
例如，在小区重选过程中，在确定Q hyst时，可以考虑该第一速度相关参数，例如移动性高的UE对应的Q hyst为Q hyst加上缩放系数sf-High，因此移动性高的UE对应的Q hyst更高，Q hyst更高则表示目标小区的质量需要更好才能被重选，用于防止该移动性高的UE在服务小区和目标小区之间的乒乓重选。
在一些实施例中，该第一小区重选参数可以由系统信息承载。该系统信息可以是系统信息类型2和/或系统信息类型3和/或系统信息类型4和/或系统信息类型5，例如，同频(邻小区与服务小区同频)的第一小区重选相关参数可以由系统信息类型2或系统类型3承载，NR异频(邻小区与服务小区异频)的第一小区重选相关参数可以由系统类型4承载，异RAT(邻小区与服务小区异RAT)的第一小区重选相关参数可以由系统类型5承载，但本申请实施例并不以此作为限制。即该终端设备通过网络设备广播的系统信息来获取上述第一小区重选相关参数。
在一些实施例中，该第一小区重选参数可以由无线资源控制(RRC)信令承载，例如RRC释放信令，另外，该RRC释放信令还可以承载时间参数，该时间参数用于指示使用该第一小区重选参数的时间，例如，该时间参数可以是定时器，该实施例可以应用在网络设备通过随机接入过程没有识别出RedCap UE或是RedCap使用场景的情况。
在一些实施例中，在终端设备是减少能力的终端设备时，该减少能力的终端设备应用与其类型或能力或使用场景对应的第一小区重选参数，忽略与其类型或能力或使用场景不对应的第一小区重选参数。
在一些实施例中，该终端设备是第二类型或第二能力的减少能力的终端设备，该终端设备在接收到对应第一类型或第一能力的减少能力的终端设备的第一小区重选参数时(该第二类型与第一类型不同，或第二能力与第一能力不同)，忽略该第一小区重选参数。
在一些实施例中，该终端设备是减少能力的终端设备，其使用场景是第二使用场景，该终端设备在接收到对应减少能力的终端设备的第一使用场景的第一小区重选参 数时(该第二使用场景与第一使用场景不同)，忽略该第一小区重选参数。
在一些实施例中，该方法还可以包括(可选，未图示)：该终端设备获取第二小区重选参数，该第二小区重选参数是为除减少能力的终端设备(RedCap UE)或减少能力的终端设备的使用场景(use case)外配置的特定小区重选参数，该第二小区重选参数包括以下参数中的至少一个：小区和/或频率的第二重选优先级的参数，第二白名单，第二黑名单，用于测量和评估小区的第二参数，第二速度相关参数，该第二白名单，第二黑名单，第二参数和第二速度相关参数与第一白名单，第一黑名单，第一参数和第一速度相关参数对应，例如该第一白名单，第一黑名单，第一参数和第一速度相关参数是针对减少能力的终端设备或减少能力的终端设备的使用场景配置的，减少能力的终端设备应用第一白名单，第一黑名单，第一参数和第一速度相关参数进行小区重选，该第二白名单，第二黑名单，第二参数和第二速度相关参数是针对非减少能力的终端设备或非减少能力的终端设备的使用场景(例如常规UE)配置的，常规UE应用第二白名单，第二黑名单，第二参数和第二速度相关参数进行小区重选。该第二小区重选参数可以由系统信息承载，该终端设备通过网络设备广播的系统信息来获取上述第二小区重选相关参数。
在一些实施例中，该终端设备是减少能力的终端设备，该终端设备在接收到该第二小区重选参数时，忽略该第二小区重选参数，并应用该第一小区重选参数进行小区重选。与之相对的是，除RedCap UE外的UE(例如常规UE)忽略该第一小区重选参数，并应用该第二小区重选参数进行小区重选。以上说明了第一小区重选参数的具体实施方式，以下结合附图4进一步说明在小区重选过程中如何应用上述第一小区重选参数。

401，终端设备获取第一小区重选参数；
402，根据该第一小区重选参数中的第一重选优先级的参数/或第一白名单和/或第一黑名单确定各小区重选相关的频率和/或小区的优先级；
例如，在确定小区或频率重选优先级时，第一白名单的小区或频率具有最高优先级，或者第一黑名单中的小区或频率具有最低优先级，其他小区或频率的优先级根据第一重选优先级的参数，或者不考虑第一白名单和/或第一黑名单，仅根据第一重选 优先级的参数确定各小区重选相关的频率和/或小区的优先级；
403，对服务小区的质量进行测量；
404，根据服务小区质量和/或上述第一重选优先级/或第一白名单和/或第一黑名单判断是否对邻小区进行测量；
例如，在确定测量小区时，只考虑第一白名单的小区作为测量小区，或者不考虑第一黑名单中的小区作为测量小区，其中，针对同频：判断服务小区质量是否高于门限S IntraaSearchP或门限S IntraaSearchQ(第一小区重选参数中配置的)；在高于门限时，不执行邻小区的同频测量，否则执行同频测量；针对异频和异RAT，如果异频(或异RAT)小区或频率优先级高于当前服务小区或频率，终端设备执行对高优先级的异频(或异RAT)测量，如果异频(或异RAT)小区或频率优先级低于或等于当前服务小区或频率，判断服务小区质量是否高于门限S nonIntraSearchP或S nonIntraSearchQ(第一小区重选参数中配置的)；在高于门限时，不执行邻小区(低优先级)的异频测量，否则执行异频(或异RAT)测量；上述S nonIntraSearchP针对小区质量是参考信号接收功率(RSRP)对应的门限，S nonIntraSearchQ针对小区质量是参考信号接收质量(RSRQ)对应的门限；
或者，在确定测量小区时，不考虑第一白名单和第一黑名单这些参数，针对同频以及异频和异RAT分别进行上述判断确定是否进行测量，重复之处不再赘述。
405，根据上述测量结果和/或上述重选优先级和/或第一白名单和/或第一黑名单，对小区进行评估，确定重选的小区；
例如，在重选评估时，只考虑第一白名单的小区作为重选候选小区，或者不考虑黑名单中的小区作为重选候选小区。
针对同频和相同优先级的异频：根据上述第一参数计算小区质量，根据测量结果以及第一参数计算R小区排序标准(具体计算方式和使用的第一参数如前所述)，根据计算结果对小区进行排序，重选最高等级(rank)的小区，如果最高等级的小区是禁止状态(barred)或者由于特定的原因不是合适(suitable)的小区，则不考虑该小区作为小区重选的候选小区，否则，重选该小区。
针对不同优先级的异频以及异RAT：如果在时间段(根据第一小区重选参数中的小区重选定时器的值Treselection RAT确定)中比当前服务小区或频率重选优先级高的异频上的一个小区的质量高于门限Thresh X,HighP(第一小区重选参数中配置的)，则执行到该高优先级的频率上的小区的重选或者将该高优先级的频率上的小区作为最好的 小区；如果在时间段(根据第一小区重选参数中的小区重选定时器的值Treselection RAT确定)中比当前服务小区或频率重选优先级低的的异频上的一个小区的质量高于门限Thresh X,LowP(第一小区重选参数中配置的)且当前服务小区的质量内低于门限Thresh Serving,LowP(第一小区重选参数中配置的)，则执行到该低优先级的频率上的小区的重选或者将该低优先级的频率上的小区作为最好的小区。如果有多于一个小区满足上述标准，则终端设备可以重选满足上述标准的最高优先级频率上的最高等级(rank)的小区，或者将满足上述标准的最高优先级频率上的最高等级(rank)的小区作为最好的小区。如果根据前述过程得到的重选的小区或最好的小区是禁止状态(barred)或者由于特定的原因不是合适(suitable)的小区，则不考虑该小区作为小区重选的候选小区，否则，重选到该小区。
或者，在评估小区时，不考虑第一白名单和第一黑名单这些参数，针对同频和相同优先级的异频，以及针对不同优先级的异频以及异RAT分别进行上述判断以确定重选的小区，重复之处不再赘述。
在一些实施例中，操作403可以是终端设备一直进行的。本申请实施例并不限定该操作在图4中的执行顺序。
以上以第一小区重选参数与减少能力的终端设备或减少能力的终端设备的使用场景对应为例进行说明，但本申请实施例并不以此作为限制，该第一小区重选参数还可以被配置为与其他类型或能力的终端设备(非RedCap UE)或其他使用场景(非RedCap UE的使用场景)对应，从而使得其他类型或能力的终端设备重选到运营商期望的小区，或者使得其他类型或能力的终端设备尽量不重选到运营商不期望的小区。例如，该其他类型或能力的终端设备可以是低复杂度终端设备或低成本终端设备或需要覆盖增强的终端设备或减少带宽的终端设备等，此处不再一一举例。
值得注意的是，以上附图4仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其它的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图4的记载。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，网络设备为减少能力的终端设备或减少能力的终端设备的使用场景配置其特定的小区重选参数，由此使得减少能力的终端设备优先重选到运营商期望的小区，例如用于服务减少能力的终端设备的小区，或者使得减少能力的终端设备尽量不重选到运营商不期望的小区，以防止大量减少能力的终端设备接入和连接而产生的拥塞，保持网络容量并对其它常规终端设备提供良好的服务。此外，操作简单且对现有常规终端设备的行为没有影响。

由上述实施例可知，通过上述确定重选优先级的方式使得终端设备优先重选到运 营商期望的小区，例如用于服务减少能力的终端设备的小区，或者使得减少能力的终端设备尽量不重选到运营商不期望的小区，以防止大量减少能力的终端设备接入和连接而产生的拥塞，保持网络容量并对其它常规终端设备提供良好的服务。此外，操作简单且对现有常规终端设备的行为没有影响。
第四方面的实施例
本申请实施例提供一种小区重选方法，从终端设备侧进行说明，例如，该终端设备可以是RedCap UE。
图7是本申请实施例的小区重选方法的一示意图，如图7所示，该方法包括：
701，该终端设备获取第三小区重选参数；
702，该终端设备根据该第三小区重选参数确定最高排序的第一小区或最好的第一小区；
703，该终端设备不将或在第二预定时间内不将对于减少能力的终端设备或减少能力的终端设备的使用场景是禁止状态的第一小区作为小区重选过程中的候选小区。
值得注意的是，以上附图7仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其它的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图7的记载。
在一些实施例中，该第三小区重选参数可以参考第一方面实施例的第一小区重选参数或第二小区重选参数，该根据该第三小区重选参数进行小区重选的过程可以参考第一方面的实施例，重复之处不再赘述。
与前述第一方面的实施例中的小区重选过程不同之处在于，在确定最高排序的第一小区或最好的第一小区后，该小区重选过程还包括：终端设备不将或在第二预定时间内不将对于减少能力的终端设备或减少能力的终端设备的使用场景是禁止状态(或不支持状态)的第一小区作为小区重选过程中的候选小区，即终端设备不考虑该第一小区作为小区重选过程中的候选小区，或者在第二预定时间内不考虑该第一小区作为小区重选过程中的候选小区，该禁止状态或不支持状态是针对减少能力的终端设备或减少能力的终端设备的使用场景配置的，具体确定方法可以参考第三方面的实施例，此处不再赘述。
在一些实施例中，该小区重选的过程还包括：该终端设备不将或在第二预定时间内不将该第一小区所在的频率上的其他小区作为小区重选过程中的候选小区；即该终端设备在小区重选过程中不考虑该第一小区，也不考虑该第一小区所在频率上的其他小区。或者第二预定时间内不考虑该第一小区，也不考虑该第一小区所在频率上的其他小区。
或者，该终端设备将该第一小区所在的频率上的其他小区作为小区重选过程中的候选小区，即该终端设备在小区重选过程中虽然不考虑该第一小区，但考虑该第一小区所在频率上的其他小区，或者在第二预定时间内虽然不考虑该第一小区，但考虑该第一小区所在频率上的其他小区。本实施例并不以此作为限制。
在一些实施例中，上述第二预定时间可以是预定义的时间或者网络配置的时间，例如为300秒等，本实施例并不以此作为限制。
在一些实施例中，可选的，在该第二预定时间是由网络设备配置时，该第三小区重选参数还可以包括该第二预定时间的参数。
在一些实施例中，在第一小区对于减少能力的终端设备或减少能力的终端设备的使用场景是禁止状态或者由于特定的原因不是合适(suitable)的小区时，该第一小区不作为减少能力的终端设备在小区重选过程中的候选小区，也就是说，减少能力的终端设备不会重选到该第一小区，该终端设备需要重新确定重选的小区，确定实施方式与第一方面的实施例中405的实施方式类似，此处不再赘述。
在一些实施例中，该最高排序的第一小区对应第一方面实施中405的同频和相同优先级的异频中的最高排序的小区，最好的第一小区对应第一方面实施例中405的不同优先级的异频或inter-RAT中的最好的小区，此处不再赘述。
由上述实施例可知，通过上述限制确定候选小区的方式使得终端设备优先重选到运营商期望的小区，例如用于服务减少能力的终端设备的小区，或者使得减少能力的终端设备尽量不重选到运营商不期望的小区，以防止大量减少能力的终端设备接入和连接而产生的拥塞，保持网络容量并对其它常规终端设备提供良好的服务。此外，操作简单且对现有常规终端设备的行为没有影响。
