具体实施方式
如背景技术所言，出于节能等考量，对于负载较低或者没有负载的小区尽量关闭并按需打开，但现有技术尚缺乏针对处于休眠状态或关闭状态的小区/载波的唤醒机制。
具体而言，在当前网络中，为了保证终端的体验，基站需要一直处于工作状态或者半睡眠状态，不能够完全关闭或者进入深度睡眠模式。而在5G网络中，由于频谱资源较多，如1吉赫(GHz)、2GHz、4GHz、6GHz和26GHz等频带(band)，所以在网络负载较低的时候，一些频带(例如4GHz、6GHz或26GHz等)对应的载波(carrier)或小区(cell)可以尽量关闭并按需打开，以此达到网络节能的目的。
一般来说，通过某些载波的开关确实可以达到网络节能的目的，但这通常是需要在网络负载较低时才能实现。当网络负载较大时，这些处于关闭或休眠态的小区反而会影响到终端执行小区重选等动作，不利于终端的体验。例如，当终端需要进行小区重选时，如果邻小区处于关闭或休眠态，终端可能找不到合适的小区进行小区重选并驻留，影响终端的移动性管理。因此，现有技术亟需一种合适的唤醒机制，能够在合适的时机唤醒处于关闭或休眠态的小区/载波。
为解决上述技术问题，本发明实施例提供一种小区唤醒方法，包括：测量第一小区的至少一个类型的参考信号，得到所述第一小区的至少一个测量结果；根据所述第一小区的至少一个测量结果和预设触发阈值的比较结果判断是否发送触发信号，其中，所述触发信号用于指示服务小区唤醒处于休眠态的邻小区。
由此，本公开方案能够在合适的时机唤醒小区，以确保终端能够顺利进行小区重选等动作，提高终端在网率。具体而言，通过测量第一小区的参考信号来衡量第一小区的信号质量，进而在第一小区的信号质量满足触发条件时发送触发信号，其中，触发条件可以例如是第一小区的至少一个测量结果大于或小于预设触发阈值。进一步，由终端根据实时测量结果确定唤醒时机，并在确定满足触发条件时发出触发信号，从而在合适的时机触发服务小区唤醒处于休眠态的邻小区。第一小区可以例如是服务小区，还可以例如是服务小区的邻小区。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明第一实施例一种小区唤醒方法的流程图。
本实施方案可以应用于允许小区(或载波)在网络负载较低时尽量关闭并按需打开以实现网络节能的应用场景。通过执行本实施方案，能够在合适的时机唤醒这些被关闭或处于休眠态的小区以精确实现按需打开，确保终端小区重选等动作能够顺利、高质量地进行。
在具体实施中，下述步骤S101～步骤S102所提供的小区唤醒方法可以由用户设备(User Equipment，简称UE，也可称为终端)中的具有小区唤醒功能的芯片执行，也可以由用户设备中的基带芯片执行。在本具体实施中，终端可以处于空闲(IDLE)态。
具体地，参考图1，本实施例所述小区唤醒方法可以包括如下步骤：
步骤S101，测量第一小区的至少一个类型的参考信号，得到所 述第一小区的至少一个测量结果；
步骤S102，根据所述第一小区的至少一个测量结果和预设触发阈值的比较结果判断是否发送触发信号，其中，所述触发信号用于指示服务小区唤醒处于休眠态的邻小区。
进一步，服务小区可以是指终端当前所驻留的小区，也即，为终端提供通信服务的小区。服务小区预先知晓其邻小区是否处于休眠态。
进一步，处于休眠态的邻小区可以是指，服务小区对应的邻小区中当前处于休眠状态或关闭状态的邻小区。处于休眠态的小区可以不执行任何发送与接收操作，或者只发送一些参考信号，如主同步信号(Primary Synchronization Signal，简称PSS)、辅同步信号(Secondary Synchronization Signal，简称SSS)等，因此终端无法基于小区重选等动作驻留在处于休眠态的邻小区。
在一个具体实施中，第一小区可以包括服务小区，也即，终端通过测量服务小区发送的至少一个类型的参考信号判断是否发送触发信号。
具体地，步骤S102可以包括步骤：当所述第一小区的至少一个测量结果均小于各自对应的第一预设阈值时，发送所述触发信号，其中，所述预设触发阈值包括至少一个第一预设阈值，不同类型的参考信号对应不同的第一预设阈值。
进一步，至少一个类型的参考信号可以包括PSS、SSS、信道状态信息参考信号(Channel State Information-Reference Signal，简称CSI-RS)和/或同步信号块(Synchronization Signal/Physical Broadcast Channel Block，简称SS/PBCH BLOCK，也即，SSB)。
进一步，至少一个测量结果可以包括参考信号接收功率(Reference Signal Received Power，简称RSRP)和/或参考信号接收质量(Reference Signal Received Quality，简称RSRQ)。
进一步，触发信号可以包括辅助信息，用于触发服务小区唤醒处于休眠态的邻小区。例如，辅助信息可以包括终端向服务小区的基站发送的序列或信号，序列可以例如是特定的随机接入前导码。又例如，辅助信息可以通过随机接入过程的第三消息(Msg3)携带。
在一个具体实施中，所述第一预设阈值可以包括专用于触发发送所述触发信号的阈值。
具体地，第一预设阈值可以由网络预先配置。例如，服务小区通过系统信息下发第一预设阈值，终端通过接收服务小区下发的系统信息确定第一预设阈值。进一步，测量不同类型的参考信号可以得到不同的测量结果，相应的，第一预设阈值可以包括RSRP阈值和RSRQ阈值。
或者，第一预设阈值可以通过协议预定义。
例如，在步骤S102中，若网络或协议仅配置RSRP阈值，则终端比较测量得到的服务小区的RSRP值和RSRP阈值的大小关系。若测量得到的服务小区的RSRP值小于RSRP阈值，则向服务小区发送辅助信息。
又例如，在步骤S102中，若网络或协议仅配置RSRQ阈值，则终端比较测量得到的服务小区的RSRQ值和RSRQ阈值的大小关系。若测量得到的服务小区的RSRQ值小于RSRQ阈值，则向服务小区发送辅助信息。
再例如，在步骤S102中，若网络或协议配置了RSRP阈值以及RSRQ阈值，则终端比较测量得到的服务小区的RSRQ值和RSRQ阈值的大小关系以及测量得到的服务小区的RSRP值和RSRP阈值的大小关系。若两个大小关系均是测量值小于对应阈值，则向服务小区发送辅助信息。
在一个具体实施中，第一预设阈值可以包括第一数值和第二数值，所述第一数值小于所述第二数值。具体而言，网络或协议可以针 对每一种第一预设阈值分别配置第一数值和第二数值两个具体数值，以便终端根据实际通信场景选择更合适的数值作为确定是否发送触发信号的触发阈值。
例如，可以配置第一RSRP阈值和第二RSRP阈值，其中第一RSRP阈值小于第二RSRP阈值。又例如，可以配置第一RSRQ阈值和第二RSRQ阈值，其中第一RSRQ阈值小于第二RSRQ阈值。再例如，可以配置第一RSRP阈值、第二RSRP阈值、第一RSRQ阈值和第二RSRQ阈值，其中第一RSRP阈值小于第二RSRP阈值，第一RSRQ阈值小于第二RSRQ阈值。
进一步，在本具体实施中，选择第一数值还是第二数值作为第一预设阈值的判别标准可以例如是终端是否满足低移动性准则。低移动性准则可以简单描述为，当服务小区的RSRP值在一段时间(TSearchDeltaP)内的变化值不超阈值(SSearchDeltaP)，即确认终端满足低移动性。
例如，第一RSRP阈值可以对应于满足低移动性准则的终端，第二RSRP阈值可以对应于不满足低移动性准则的终端。由此，对于满足低移动性的终端，意味着其切换小区的需求较小，则本具体实施通过给满足低移动性准则的终端设置数值较小的第一预设阈值，使得这类终端能够晚一点触发小区唤醒机制。
进一步，在步骤S102之前，本实施例所述方法还可以包括步骤：若终端满足低移动性准则，则将所述第一数值确定为所述第一预设阈值；若终端不满足低移动性准则，则将所述第二数值确定为所述第一预设阈值。由此，可以根据终端的当前移动性情况合理确定第一预设阈值，使得低移动性的终端能够更晚地触发辅助信息。
在一个具体实施中，第一预设阈值可以包括触发启动同频测量的阈值。也就是说，在本具体实施中，沿用小区重选准则中配置的同频测量触发阈值作为第一预设阈值以供终端判断是否发送辅助信息。例如，第一预设阈值可以为协议定义的阈值(SIntraSearchP)和阈值 (SIntraSearchQ)。
进一步，在步骤S102中，当终端满足同频小区测量准则时，可以向服务小区发送辅助信息。
在一个具体实施中，第一预设阈值可以包括触发启动异频测量的阈值。也就是说，在本具体实施中，沿用小区重选准则中配置的异频测量触发阈值作为第一预设阈值以供终端判断是否发送辅助信息。例如，第一预设阈值可以为协议定义的阈值(SnonIntraSearchP)和阈值(SnonIntraSearchQ)。
进一步，在步骤S102中，当终端满足异频小区测量准则时，可以向服务小区发送辅助信息。
在一个具体实施中，对于第一预设阈值可以为触发启动同频测量的阈值或者触发启动异频测量的阈值的情形，步骤S102可以包括步骤：当所述第一小区的至少一个测量结果均小于各自对应的第一预设阈值，且在第一时长内未找到满足小区重选准则的小区时，发送所述触发信号。
具体地，第一时长可以由网络预先配置。例如，服务小区的基站可以通过无线资源控制(Radio Resource Control，简称RRC)信令配置第一时长。
由此，有利于避免不必要的小区唤醒，有益于网络节能。具体而言，通过设置第一时长，可以使得终端在确定满足同频小区测量准则或异频小区测量准则时先在已经处于工作状态(即非休眠态)的邻小区里寻找满足小区重选准则的小区。若在第一时长期间未找到合适的目标小区，终端再发送辅助信息以触发服务小区唤醒处于休眠态的邻小区。
在一个具体实施中，第一预设阈值可以包括非小区边缘判别的阈值。也就是说，本具体实施中沿用非小区边缘准则中的相应阈值作为第一预设阈值。
具体而言，非小区边缘准则可以简单描述为，如果没有配置RSRQ阈值(SSearchThresholdQ)，则当服务小区的RSRP大于对应的阈值(SSearchThresholdP)时，终端满足非小区边缘准则，否则不满足非小区边缘准则。
如果配置了RSRQ阈值(SSearchThresholdQ)，则当服务小区的RSRP大于对应的阈值(SSearchThresholdP)，且RSRQ大于对应的阈值(SSearchThresholdQ)时，终端满足非小区边缘准则，否则不满足非小区边缘准则。
相应的，在本具体实施中，第一预设阈值可以为阈值(SSearchThresholdP)，或者，第一预设阈值可以为阈值(SSearchThresholdP)和阈值(SSearchThresholdQ)。
进一步，在步骤S102中，当终端不满足非小区边缘准则时，则向服务小区发送辅助信息。否则，终端不向服务小区发送辅助信息。
在一个具体实施中，第一小区可以包括服务小区对应的邻小区，也即，终端通过测量邻小区发送的至少一个类型的参考信号判断是否发送触发信号。
具体地，无论是否处于休眠态，服务小区对应的邻小区均会发送至少一个类型的参考信号。终端测量周边任意邻小区发送的参考信号。
在一个可能的示例中，处于休眠态的邻小区较之处于工作状态的邻小区可以发送更为简化的参考信号。例如，处于休眠态的邻小区可以发送PSS/SSS或者CSI-RS，处于工作状态的邻小区可以发送SSB。
进一步，步骤S102可以包括步骤：当所述第一小区的至少一个测量结果均大于各自对应的第二预设阈值时，发送所述触发信号，其中，所述第二预设阈值为专用于触发所述触发信号的阈值，不同类型的参考信号对应不同的第二预设阈值。
与第一预设阈值相类似，第二预设阈值可以由网络预先配置。例 如，服务小区通过系统信息下发第二预设阈值，终端通过接收服务小区下发的系统信息确定第二预设阈值。进一步，测量邻小区的不同类型的参考信号可以得到不同的测量结果，相应的，第二预设阈值可以包括RSRP阈值和RSRQ阈值。
或者，第二预设阈值可以通过协议预定义。
进一步，终端在步骤S101中可以测量服务小区对应的多个邻小区发送的简化的参考信号以确定各邻小区的RSRP值(和/或RSRQ值)，当发现存在一个邻小区的RSRP值(和/或RSRQ值)大于RSRP阈值(和/或RSRQ阈值)时即发送触发信号。
进一步，触发信号可以包括辅助信息，用于触发服务小区唤醒处于休眠态的邻小区。例如，辅助信息可以包括终端向服务小区的基站发送的序列或信号，序列可以例如是特定的随机接入前导码。又例如，辅助信息可以通过随机接入过程的第三消息(Msg3)携带。
在一个具体实施中，辅助信息可以包括所述第一小区的小区标识(Identification，简称ID)。也就是说，终端可以将测量发现的至少一个测量结果均大于各自对应的第二预设阈值的第一小区确定为目标邻小区，并通过辅助信息将目标邻小区的小区ID上报至服务小区对应的基站。相应的，服务小区的基站可以根据辅助信息中携带的小区ID有指向性的唤醒特定邻小区。
进一步，第一小区的小区ID可以通过第一小区发送的参考信号获得。例如，终端可以基于第一小区发送的PSS/SSS获得第一小区的小区ID。
在一个具体实施中，在第一小区包括所述服务小区对应的邻小区的场景中，触发信号可以包括唤醒信号，所述唤醒信号用于唤醒处于休眠态的邻小区。
具体地，在执行步骤S102确定需要发送触发信号后，终端可以跳过服务小区，而是直接向外发送唤醒信号。例如，终端可以在特定 频点/频率范围发送序列/信号，位于终端周边的处于休眠态的邻小区会在该特定频点或频率范围进行接收。接收到该唤醒信号的处于休眠态的邻小区会被唤醒。
进一步，唤醒信号可以例如是前导码序列，或者其他类型的序列，或者信号。
由此，通过终端之间进行小区唤醒，有利于降低时延。
在一个具体实施中，步骤S102可以是在接收到指示发送触发信号的系统消息时执行的。
具体地，网络可以通过系统消息指示终端是否需要向服务小区发送辅助信息。若指示需要，则终端执行步骤S102以确定是否发送辅助信息等触发信号。若指示不需要，则终端不需要执行步骤S102。
例如，当网络当前业务负载较大，网络内没有处于休眠态的小区时，网络可以选择关闭终端的触发信号上报功能，以更好的节能。
由上，采用本实施方案，能够在合适的时机唤醒小区，以确保终端能够顺利进行小区重选等动作，提高终端在网率。具体而言，通过测量第一小区的参考信号来衡量第一小区的信号质量，进而在第一小区的信号质量满足触发条件时发送触发信号，其中，触发条件可以例如是第一小区的至少一个测量结果大于或小于预设触发阈值。由此，由终端根据实时测量结果确定唤醒时机，并在确定满足触发条件时发出触发信号，从而在合适的时机触发服务小区唤醒处于休眠态的邻小区。第一小区可以例如是服务小区，还可以例如是服务小区的邻小区。
图2是本发明第二实施例一种小区唤醒装置2的结构示意图。本领域技术人员理解，本实施例所述小区唤醒装置2可以用于实施上述图1所述实施例中所述的方法技术方案。
具体地，参考图2，本实施例所述小区唤醒装置2可以包括：测量模块21，用于测量第一小区的至少一个类型的参考信号，得到所述第一小区的至少一个测量结果；判断模块22，用于根据所述第一 小区的至少一个测量结果和预设触发阈值的比较结果判断是否发送触发信号，其中，所述触发信号用于指示服务小区唤醒处于休眠态的邻小区。
关于所述小区唤醒装置2的工作原理、工作方式的更多内容，可以参照上述图1中的相关描述，这里不再赘述。
在具体实施中，上述的小区唤醒装置可以对应于用户设备中具有小区唤醒功能的芯片，或者对应于具有数据处理功能的芯片，例如片上系统(System-On-a-Chip，简称SOC)、基带芯片等；或者对应于用户设备中包括具有小区唤醒功能芯片的芯片模组；或者对应于具有数据处理功能芯片的芯片模组，或者对应于用户设备。
图3是本发明第三实施例一种小区唤醒方法的流程图。
本实施方案可以应用于允许小区(或载波)例如在网络负载较低时尽量关闭并按需打开以实现网络节能的应用场景。通过执行本实施方案，能够在合适的时机唤醒这些被关闭或处于休眠态的小区以精确实现按需打开，确保终端小区重选等动作能够顺利、高质量地进行。
在具体实施中，下述步骤S301～步骤S302所提供的小区唤醒方法可以由网络设备中的具有小区唤醒功能的芯片执行，也可以由网络设备中的基带芯片执行。在本具体实施中，网络设备可以例如是服务小区的基站。
具体地，参考图3，本实施例所述小区唤醒方法可以包括如下步骤：
步骤S301，接收触发信号，其中，所述触发信号是根据第一小区的至少一个测量结果和预设触发阈值的比较结果判断是否发送的，所述第一小区的至少一个测量结果是对所述第一小区的至少一个类型的参考信号的测量结果；
步骤S302，根据所述触发信号发送唤醒指令，以唤醒处于休眠态的邻小区。
本领域技术人员理解，所述步骤S301至步骤S302可以视为与上述图1所示实施例所述步骤S101至步骤S102相呼应的执行步骤，两者在具体的实现原理和逻辑上是相辅相成的。因而，本实施例中涉及名词的解释可以参考图1所示实施例的相关描述，这里不再赘述。例如，终端在执行图1中步骤S102确定发送触发信号后，相应的，服务小区的基站执行本实施方案中步骤S301以接收终端发送的触发信号。
在一个具体实施中，唤醒指令可以用于唤醒服务小区周边不特定的一个或多个处于休眠态的邻小区。例如，响应于接收到触发信号，服务小区的基站可以向周边已知的所有处于休眠态的邻小区发送唤醒指令。
在一个变化例中，唤醒指令可以用于唤醒特定的处于休眠态的邻小区。
具体地，第一小区可以包括邻小区，触发信号可以包括所述第一小区的小区标识。
进一步，步骤S302可以包括步骤：根据所述第一小区的小区标识向所述第一小区发送唤醒指令，以唤醒处于休眠态的所述第一小区。
例如，终端在执行图1中步骤S102确定需要发送触发信号时，将目标邻小区的小区ID携带于辅助信息中一并发送至服务小区的基站。响应于接收到包含有目标邻小区的小区ID的辅助信息，服务小区的基站在执行步骤S302时直接唤醒该目标邻小区。
在一个具体实施中，唤醒指令可以包括指示信息，所述指示信息用于指示处于休眠态的邻小区执行第一动作。
具体地，所述第一动作可以包括以下至少一项：发送同步信号块SSB；发送系统信息块(System Information Block，简称SIB)或其他系统信息(Other System Information，简称OSI)；接收物理随机接入 信道(Physical Random Access Channel，简称PRACH)。
或者，唤醒指令可以不包含需要处于休眠态的邻小区执行的特定动作，而是仅用于唤醒处于休眠态的邻小区。处于休眠态的邻小区被唤醒后，根据预定义被唤醒后需要执行的动作进行后续操作。
进一步，服务小区的基站可以通过基站间Xn接口向处于休眠态的邻小区的基站发送唤醒指令。
在一个具体实施中，在步骤S301之前，本实施例所述方法还可以包括步骤：发送系统消息，其中，所述系统消息用于指示是否发送触发信号。
进一步，如果系统消息指示需要发送辅助信息，但终端在执行图1中步骤S102发送触发信号后，网络侧发现当前所有小区都是非休眠态的，则执行本实施方案的服务小区的基站可以选择不响应该辅助信息。
在一个具体实施中，第一小区可以包括服务小区或邻小区，触发信号可以包括辅助信息，辅助信息可以用于触发所述服务小区唤醒处于休眠态的邻小区。
由上，采用本实施方案，服务小区基于触发信号执行对其处于休眠态的邻小区的唤醒动作，以实现由终端触发的小区唤醒，使得对休眠态邻小区的唤醒操作符合终端期望。进一步，被唤醒的邻小区可能有利于终端的小区重选等操作。

关于所述小区唤醒装置4的工作原理、工作方式的更多内容，可以参照上述图3中的相关描述，这里不再赘述。
在具体实施中，上述的小区唤醒装置可以对应于网络设备中具有小区唤醒功能的芯片，或者对应于具有数据处理功能的芯片，例如片上系统(System-On-a-Chip，简称SOC)、基带芯片等；或者对应于网络设备中包括具有小区唤醒功能芯片的芯片模组；或者对应于具有数据处理功能芯片的芯片模组，或者对应于网络设备。
图5是本发明第五实施例一种小区唤醒方法的流程图。
本实施方案可以应用于允许小区(或载波)例如在网络负载较低时尽量关闭并按需打开以实现网络节能的应用场景。通过执行本实施方案，能够在合适的时机唤醒这些被关闭或处于休眠态的小区以精确实现按需打开，确保终端小区重选等动作能够顺利、高质量地进行。
在具体实施中，下述步骤S501～步骤S502所提供的小区唤醒方法可以由网络设备中的具有小区唤醒功能的芯片执行，也可以由网络设备中的基带芯片执行。在本具体实施中，网络设备可以例如是处于休眠态的邻小区的基站。
具体地，参考图5，本实施例所述小区唤醒方法可以包括如下步骤：

步骤S502，根据所述唤醒指令或触发信号从休眠态切换至非休眠态。
本领域技术人员理解，所述步骤S501至步骤S502可以视为与上述图1所示实施例所述步骤S101至步骤S102相呼应的执行步骤，或者可以视为与上述图3所示实施例所述步骤S301至步骤S302相呼应的执行步骤，两者在具体的实现原理和逻辑上是相辅相成的。因而，本实施例中涉及名词的解释可以参考图1和图3所示实施例的相关描述，这里不再赘述。
例如，终端在执行图1中步骤S102确定发送触发信号后，相应的，处于休眠态的邻小区的基站执行本实施方案中步骤S501以接收终端发送的触发信号。在本示例中，终端发送的触发信号可以例如是上述图1所示实施例中所述的唤醒信号。
又例如，终端在执行图1中步骤S102确定发送触发信号后，相应的，服务小区的基站执行本实施方案中步骤S301和步骤S302以基于终端发送的触发信号生成唤醒指令并发送，相应的，处于休眠态的邻小区的基站执行本实施方案中步骤S501以接收服务小区的基站发送的唤醒指令。
在一个具体实施中，唤醒指令可以包括指示信息，所述指示信息用于指示处于休眠态的邻小区执行第一动作。相应的，步骤S502可以包括步骤：执行所述指示信息所指示的第一动作。
具体地，第一动作可以包括以下至少一项：发送SSB；发送SSB或OSI；接收PRACH。其中，通过接收PRACH可以接收终端发送的前导码序列(即第一消息MSG1)。
在一个具体实施中，在步骤S501之前，本实施例所述方法还可以包括步骤：处于休眠态期间，发送至少一个类型的参考信号。例如，处于休眠态的邻小区的基站至少广播PSS/SSS。
进一步，处于休眠态的邻小区的基站还可以监听特定频点或频率范围，以及时接收终端直接发送的唤醒信号。
由上，采用本实施例方案，处于休眠态的邻小区响应于触发信号 或基于触发信号产生的唤醒指令从休眠态或关闭状态被唤醒。这对于网络更好地为终端提供通信支持可能是有益的。

在本应用场景中，假设网络中至少一个小区处于休眠态，终端存在进行小区重选以从当前连接的服务小区切换到其他小区的需求。处于休眠态的小区可以不执行任何发送与接收操作，或者只发送一些参考信号，例如PSS/SSS等。
终端可以执行上述图1所示实施例的方案，服务小区的基站可以执行上述图3所示实施例的方案，服务小区对应的处于休眠态的邻小区的基站可以上述图5所示实施例的方案。
具体地，参考图7，网络可以通过服务小区执行操作s71，以通过系统信息配置第一预设阈值。在本示例中，第一预设阈值可以包括触发辅助信息发送的RSRP阈值。进一步，在本示例中，系统信息还指示终端需要向服务小区发送辅助信息。
响应于接收到系统信息，终端可以确定触发辅助信息发送的RSRP阈值。
进一步，终端可以执行操作s72，以通过测量服务小区发送的参考信号确定服务小区的RSRP值。
当测量得到的服务小区的RSRP值小于网络配置的RSRP阈值 时，终端可以执行操作s73，以向服务小区的基站发送辅助信息。在本示例中，辅助信息可以是终端向服务小区的基站发送的序列(例如特定的随机接入前导码)或者信号。或者，辅助信息也可以通过随机接入过程的第三消息(即Msg3)携带。
响应于接收到辅助信息，服务小区的基站可以执行操作s74，以向周边处于休眠态的邻小区发送唤醒指令。唤醒指令可以包括指示信息，以指示处于休眠态的邻小区执行第一动作。在本示例中，服务小区的基站可以通过基站间Xn接口向周边处于休眠态的邻小区的基站发送唤醒指令。
响应于接收到唤醒指令，处于休眠态的邻小区可以执行操作s75，以从休眠态切换至非休眠态。此时，终端有可能小区重选至该切换至非休眠态的邻小区。
由此，终端通过辅助信息指示网络触发当前服务小区周边处于休眠状态的邻小区发送SSB，或者发送SIB/OSI，或者接收PRACH等，以使终端可以小区重选至当前服务小区周边的邻小区。
在一个变化例中，图7所示操作s71中通过系统信息配置的第一预设阈值可以包括触发辅助信息发送的RSRQ阈值。相应的，操作s72中，终端通过测量服务小区发送的参考信号确定服务小区的RSRQ值，并在测量得到的服务小区的RSRQ值小于网络配置的RSRQ阈值时执行操作s73。
在另一个变化例中，图7所示操作s71中通过系统信息配置的第一预设阈值可以包括触发辅助信息发送的RSRP阈值与RSRQ阈值。相应的，操作s72中，终端通过测量服务小区发送的参考信号确定服务小区的RSRP值与RSRQ值，并在测量得到的服务小区的RSRP值小于网络配置的RSRP阈值，且测量得到的服务小区的RSRQ值小于网络配置的RSRQ阈值时执行操作s73。
在又一个变化例中，图7所示操作s71中通过系统信息配置的第 一预设阈值可以包括触发辅助信息发送的第一RSRP阈值和第二RSRP阈值，其中第一RSRP阈值对应于满足低移动性准则的终端，第二RSRP阈值对应于不满足低移动性准则的终端，第一RSRP阈值小于第二RSRP阈值。
若终端满足低移动性准则，则当测量得到的服务小区的RSRP值小于第一RSRP阈值时执行操作s73。
若终端不满足低移动性准则，则当测量得到的服务小区的RSRP值小于第二RSRP阈值时执行操作s73。
在又一个变化例中，图7所示操作s71中通过系统信息配置的第一预设阈值可以包括触发辅助信息发送的第一RSRQ阈值和第二RSRQ阈值，其中第一RSRQ阈值对应于满足低移动性准则的终端，第二RSRQ阈值对应于不满足低移动性准则的终端，第一RSRQ阈值小于第二RSRQ阈值。
若终端满足低移动性准则，则当测量得到的服务小区的RSRQ值小于第一RSRQ阈值时操作s73。
若终端不满足低移动性准则，则当测量得到的服务小区的RSRQ值小于第二RSRQ阈值时操作s73。
在又一个变化例中，图7所示操作s71中通过系统信息配置的第一预设阈值可以包括触发辅助信息发送的第一RSRP阈值、第一RSRQ阈值、第二RSRP阈值和第二RSRQ阈值，其中第一RSRP阈值和第一RSRQ阈值对应于满足低移动性准则的终端，第二RSRP阈值和第二RSRQ阈值对应于不满足低移动性准则的终端。第一RSRP阈值小于第二RSRP阈值，第一RSRQ阈值小于第二RSRQ阈值。
若终端满足低移动性准则，则当测量得到的服务小区的RSRP值小于第一RSRP阈值，且测量得到的服务小区的RSRQ值小于第一RSRQ阈值时执行操作s73。
若终端不满足低移动性准则，则当测量得到的服务小区的RSRP 值小于第二RSRP阈值，且测量得到的服务小区的RSRQ值小于第二RSRQ阈值时执行操作s73。
在又一个变化例中，图7所示操作s71中的系统信息可以并未专门配置用于触发辅助信息发送的第一预设阈值。相应的，终端可以将网络配置的同频小区测量准则中触发启动同频测量的阈值确定为第一预设阈值。换言之，当终端满足同频小区测量准则时即执行操作s73。
进一步，图7所示操作s71中的系统信息中可以配置第一时长。相应的，当终端满足同频小区测量准则，且在第一时长期间未找到合适的目标小区(即满足小区重选准则的小区)，则终端执行操作s73。
在又一个变化例中，图7所示操作s71中的系统信息可以并未专门配置用于触发辅助信息发送的第一预设阈值。相应的，终端可以将网络配置的异频小区测量准则中触发启动异频测量的阈值确定为第一预设阈值。换言之，当终端满足异频小区测量准则时即执行操作s73。
进一步，图7所示操作s71中的系统信息中可以配置第一时长。相应的，当终端满足异频小区测量准则，且在第一时长期间未找到合适的目标小区(即满足小区重选准则的小区)，则终端执行操作s73。
在又一个变化例中，图7所示操作s71中的系统信息可以并未专门配置用于触发辅助信息发送的第一预设阈值。相应的，终端可以将网络配置的小区边缘准则中的相应阈值确定为第一预设阈值。也就是说，当终端不满足非小区边缘准则时执行操作s73。
图8是本发明实施例第二个典型应用场景的信令交互图。
在本应用场景中，假设网络中至少一个小区处于休眠态，终端存在进行小区重选以从当前连接的服务小区切换到其他小区的需求。处于休眠态的小区可以不执行任何发送与接收操作，或者只发送一些参考信号，例如PSS/SSS等。
终端可以执行上述图1所示实施例的方案，服务小区的基站可以执行上述图3所示实施例的方案，服务小区对应的处于休眠态的邻小区的基站可以上述图5所示实施例的方案。
具体地，触发辅助信息发送的RSRP(和/或RSRQ)阈值可以是协议预定义的。
进一步，参考图8，终端执行操作s81，以通过测量邻小区发送的参考信号确定邻小区的RSRP值(和/或RSRQ值)。在本示例中，终端测量的邻小区可以是周边能够测量到的任意多个邻小区。
当存在邻小区的RSRP(和/或RSRQ)值大于RSRP阈值(和/或RSRQ阈值)时，终端执行操作s82，以向服务小区发送辅助信息。
响应于接收到辅助信息，服务小区的基站可以执行操作s83，以向周边处于休眠态的邻小区发送唤醒指令。唤醒指令可以包括指示信息，以指示处于休眠态的邻小区执行第一动作。在本示例中，服务小区的基站可以通过基站间Xn接口向周边处于休眠态的邻小区的基站发送唤醒指令。
响应于接收到唤醒指令，处于休眠态的邻小区可以执行操作s84，以从休眠态切换至非休眠态。此时，终端有可能小区重选至该切换至非休眠态的邻小区。
在本示例中，唤醒指令指向的对象可以是服务小区周边不特定的处于休眠态的邻小区。该不特定的处于休眠态的邻小区可以包括终端测量得到的RSRP(和/或RSRQ)值大于RSRP阈值(和/或RSRQ阈值)的邻小区，也可以不包括终端测量得到的RSRP(和/或RSRQ)值大于RSRP阈值(和/或RSRQ阈值)的邻小区。
在一个变化例中，将测量得到的RSRP(和/或RSRQ)值大于RSRP阈值(和/或RSRQ阈值)的邻小区确定为目标邻小区，终端可以通过测量目标邻小区发送的参考信号获取目标邻小区的小区ID并携带在发送的辅助信息中以上报至服务小区对应的基站。相应的，在 执行操作s83时，服务小区的基站基于终端上报的辅助信息，触发目标邻小区发送SSB，或者发送SIB/OSI，或者接收PRACH等。
由此，在本变化例中，唤醒指令指向的对象可以是服务小区周边特定的处于休眠态的邻小区。具体而言，被唤醒的处于休眠态的邻小区是终端在辅助信息中上报的小区ID所唯一标识的目标邻小区。
图9是本发明实施例第三个典型应用场景的信令交互图。
在本应用场景中，假设网络中至少一个小区处于休眠态，终端存在进行小区重选以从当前连接的服务小区切换到其他小区的需求。处于休眠态的小区可以不执行任何发送与接收操作，或者只发送一些参考信号，例如PSS/SSS等。
终端可以执行上述图1所示实施例的方案，服务小区的基站可以执行上述图3所示实施例的方案，服务小区对应的处于休眠态的邻小区的基站可以上述图5所示实施例的方案。
具体地，参考图9，网络可以通过服务小区执行操作s91，以通过系统信息配置第一预设阈值。在本示例中，第一预设阈值可以包括触发辅助信息发送的RSRP阈值和RSRQ阈值。
进一步，终端执行操作s92，以通过测量邻小区发送的参考信号确定邻小区的RSRP值和RSRQ值。在本示例中，终端测量的邻小区可以是周边能够测量到的任意多个邻小区。
当存在这样一个处于休眠态的邻小区，终端测量得到的该处于休眠态的邻小区的RSRP值大于RSRP阈值，且测量得到的该处于休眠态的邻小区的RSRQ值也大于RSRQ阈值。此时，终端可以执行操作s93，以向该处于休眠态的邻小区发送唤醒信号。
处于休眠态的邻小区对应的基站收到所述唤醒信号后，可以执行操作s94，以开始发送SSB，或者发送SIB/OSI，或者接收PRACH等。此时，终端可以小区重选至该原本处于休眠态的邻小区。
虽然本发明披露如上，但本发明并非限定于此。任何本领域技术人员，在不脱离本发明的精神和范围内，均可作各种更动与修改，因此本发明的保护范围应当以权利要求所限定的范围为准。
