Description

一种小区测量方法及装置
本申请要求在2019年02月02日提交中国专利局、申请号为201910106362.1、申请名称为“一种小区测量方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种小区测量方法及装置。
背景技术
移动性管理是无线移动通信中的重要组成部分。移动性管理是为了保证网络与终端设备之间的通信链路不因终端设备的移动而中断所涉及到的相关内容。根据终端设备的状态大致上可以分为空闲态(RRC_IDLE state)移动性管理和连接态(RRC_CONNECTED state)移动性管理两部分。在空闲态下，移动性管理主要指的是小区选择/重选(cell selection/reselection)的过程，在连接态下，移动性管理主要指的是小区切换(handover)。不论是小区选择/重选还是切换，都是基于移动性测量的结果进行的。因此移动性测量是移动性管理的基础。
在移动性测量过程中，终端设备基于网络设备发送的测量配置信息对小区进行测量，并将测量报告上报给网络设备。其中，最常见的移动向测量是终端设备基于同步信号/物理广播信道块((synchronization signal，SS)/(physical broadcast channel，PBCH)block，SSB)的测量和基于信道状态信息参考信号(channel state information-reference signal，CSI-RS)的测量。
目前在终端设备基于SSB测量时，需要对待测的SSB频点上的所有小区进行测量，由于SSB对应的参考信号是用物理小区标识(physical cell identifier，PCI)加扰的，所以终端设备需要在一个SSB的频点上用所有的PCI去试出要测量的小区，这样会使终端设备非常耗电，造成资源浪费。

具体实施方式
下面将结合附图对本申请作进一步地详细描述。
本申请实施例提供一种小区测量方法及装置，用以解决现有技术中终端设备非常耗电，造成资源浪费的问题。其中，本申请所述方法和装置基于同一发明构思，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
众所周知，移动性管理是无线通信系统中的重要组成部分。根据终端设备的状态大致上可以分为空闲态(RRC_IDLE state)移动性管理和连接态(RRC_CONNECTED state)移动性管理两部分。在空闲态下，移动性管理主要指的是小区选择/重选(cell selection/reselection)的过程，在连接态下，移动性管理主要指的是小区切换(handover)。不论是小区选择/重选还是切换，都是基于移动性测量的结果进行的。因此移动性测量是移动性管理的基础。
具体的，移动性测量的过程可以包括如下步骤：
步骤1，网络设备向终端设备发送测量配置信息(measConfig)。
步骤2，所述终端设备基于测量配置信息进行小区测量，并向网络设备上报测量结果。
其中，测量配置信息中可以包括测量对象(measurement object，MO)、上报配置(reporting configuration，reportConfig)、测量标识(measurement identity，measId)、测量量配置(quantity configuration)、测量间隔配置等。
下面对测量配置信息中的部分信息进行说明：
测量对象(measurement object，MO：在LTE系统中一个MO对应一个频点，测量对象的测量参数包括该频点上测量资源的配置情况，例如该频点上的小区列表等等。在新无线控制器(new radio，NR)系统中，对于同频测量和异频测量，测量对象指示要测的参考信号的频域/时域位置和子载波间隔，对于异系统的E-UTRA测量，测量对象对应一个E-UTRA频点；一个MO的测量参数可以包括SSB对应的测量参数，还可以包括CSI-RS对应的测量参数。
上报配置：上报配置的测量参数包括参考信号的类型，上报类型，以及上报的格式等等。其中，上报类型包括事件触发上报或者周期性触发上报或小区全球标识(cell global identification，CGI)上报。若上报类型为事件触发上报，则测量参数还包括事件类型、门限值以及满足触发条件的持续时间(time to trigger)等。目前，LTE系统中事件类型有：事件A1，服务小区触发量高于门限值；事件A2，服务小区的触发量低于门限值；事件A3，邻小区触发量在考虑偏移值后好于主小区(primary cell，PCell)/主辅小区(primary secondary cell，PSCell)的触发量；事件A4，邻小区触发量高于门限值；事件A5，服务小区触发量低于第一门限值，且邻小区触发量高于第二门限值；事件A6，邻小区触发量在考虑偏移值后好于辅小区(secondary cell，SCell)触发量。若上报方式为周期性触发上报，则测量参数还包括上报周期以及周期性触发的目的等等。
测量标识：一个测量标识是一个测量对象和一个上报配置的结合。两者结合在一起就确定了对于一个测量对象的测量的各种细节。例如，如图1示出了测量标识、测量对象(MO) 和上报配置之间的关系示意。
测量量配置：终端设备在上报测量结果之前，首先对触发量进行层3滤波。测量量配置指的是层3滤波系数的配置。
测量间隔配置：当测量和数据传输不能同时进行，需要网络为其配置测量间隔。
目前在终端设备进行小区测量时，需要对所有的小区进行测量。但是在终端设备基于SSB测量时，由于SSB对应的参考信号是用物理小区标识(physical cell identifier，PCI)加扰的，所以终端设备需要在一个SSB的频点上用所有的PCI去试出要测量的小区，这样会使终端设备非常耗电，造成资源浪费。基于此，本申请实施例提出了一种小区测量方法，可以解决终端设备耗电造成资源浪费的问题。
为了更加清晰地描述本申请实施例的技术方案，下面结合附图，对本申请实施例提供的小区测量方法及装置进行详细说明。
图2示出了本申请实施例提供的小区测量方法适用的一种可能的通信系统的架构，所述通信系统的架构中可以包括终端设备和网络设备。其中：
所述网络设备，可以是无线接入设备，所述无线接入设备可以是普通的基站(如节点B(Node B，NB)或演进型节点B(evolved Node B，eNB))，可以是无线网络控制器(radio network controller，RNC)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)，可以是新无线控制器(new radio controller，NR controller)，可以是5G系统中的gNode B(gNB)，可以是集中式网元(Centralized Unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站，可以是中继(relay)，可以是分布式网元(Distributed Unit)，可以是接收点(transmission reception point，TRP)或传输点(transmission point，TP)或者任何其它无线接入设备，但本申请实施例不限于此，此处不再一一列举。
所述终端设备，又可以称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。例如，所述终端设备可以包括具有无线连接功能的手持式设备、车载设备、计算设备、移动台(mobile station，MS)或连接到无线调制解调器的其他处理设备等，以及经接入网与一个或多个核心网进行通信的移动终端。目前，所述终端设备可以是：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端，或智慧家庭(smart home)中的无线终端等。
需要说明的是，图2所示的通信系统的架构中不限于仅包含图中所示的设备，还可以包含其它未在图中表示的设备，具体本申请在此处不再一一列举。
需要说明的是，图2所示的通信系统并不构成本申请实施例能够适用的通信系统的限定。所述通信系统可以是各类通信系统，例如，可以是长期演进(long term evolution，LTE)，也可以是第五代(5G)通信系统，也可以为通用地面无线接入(universal terrestrial radio access，UTRA)、演进的UTRA(E-UTRAN)、新无线技术(new radio，NR)、GSM/EDGE 无线接入网-电路交换域(GSM EDGE radio access network-circuit switched，GERAN-CS)、GSM/EDGE无线接入网-数据交换域(GSM EDGE radio access network–packet switched，GERAN-PS)、码分多址(code division multiple access，CDMA)2000-1XRTT、和多无线接入技术双连接(Multi-RAT Dual-Connectivity，MR-DC)等，还可以是多种通信系统的混合架构，如LTE与5G混合架构等。当然，本申请实施例的方法还适用于未来的各种通信系统，例如6G或者其他通信网络等。
本申请实施例提供的一种小区测量方法，适用于如图2所示的通信系统。参阅图3所示，该方法的具体流程可以包括：
步骤301：网络设备确定指示信息，所述指示信息指示所述终端设备进行小区测量得到N个满足小区质量参数阈值的小区，N为大于1的整数。
步骤302：所述网络设备向所述终端设备发送所述指示信息。
步骤303：所述终端设备根据所述指示信息进行小区测量。
其中，所述网络设备可以通过信令RRCReconfiguration向所述终端设备发送所述指示信息。
在一种可选的实施方式中，所述指示信息在不同的场景下可以有不同的表现形式，例如，可以体现为以下四种示例：
示例a1：所述指示信息中可以直接包括所述N和需要满足的所述小区质量参数阈值，以使所述终端设备进行小区测量得到N个满足所述小区质量参数阈值的小区。需要说明的是，本申请实施例中提到的满足所述小区质量参数阈值可以理解为不小于所述小区质量参数阈值或者大于所述小区质量参数阈值，或者其他任何满足条件的限定，本申请对此不作具体限定。在此场景中，小区质量参数可以为小区的参考信号接收功率(reference signal receiving power，RSRP)、小区的信号与干扰加噪声比(signal to interference plus noise ratio，SINR)等等。
示例a2：所述指示信息可以只包含所述N，其中，是否满足小区质量参数阈值可以通过小区是否触发了事件来判断，例如，可以是小区的触发量是否高于门限的触发事件。但是在这种情况下，所述终端设备配置为事件触发类型。例如，对于事件触发(event-Triggered)，“满足小区质量参数阈值”可通过该小区是否满足进入条件(entering condition)来判断，即，当一个小区触发了该事件，则认为该小区满足质量参数阈值。又例如，“不满足小区质量参数阈值”可复用该小区满足离开条件(leaving condition)，即当一个小区满足leaving condition时，就将该小区从小区触发列表(cellsTriggeredList)移除，所述终端设备认为该小区不再属于满足小区质量参数阈值的小区，通过上述方法可以得到满足小区质量参数阈值的小区。
示例a3：所述指示信息指示所述N为最大上报邻区数(maxReportCells)，此时所述N复用所述maxReportCells。在这种场景下，所述指示信息中可以包括一个模式指示，所述模式指示可以为省电模式指示。也就是说当所述指示信息中包含了所述模式指示时，所述终端设备可以自动识别到需要参考所述maxReportCells来确定需要测量得到的小区个数。此外，在此场景下所述满足小区质量参数阈值的具体情况可以参见上述示例a1或示例a2，此处不再重复赘述。
示例a4：所述指示信息指示所述N为协议规定好的固定值，例如所述N可以是3、4等不同的固定值。其中，根据不同的实际情况，所述N的取值可以不相同，例如，标准协 议38.133v15.4.0中规定了对于每个同频/异频频点，终端设备至少要能够监测4个小区，此时所述N可以为4，或者所述N可以对于同频是3(4减去1个服务小区)对于异频是4。需要说明的是上述仅仅是一个举例，并不是对所述N的限定，应理解所述N还可以是协议规定的除3或4以外的其他固定值，本申请对此不作具体限定。在此场景中，所述指示信息中同样可以包括一个模式指示，所述模式指示为省电模式指示，具体可以参见示例a3。此外，所述满足小区质量参数阈值的具体情况同样可以参见上述示例a1或示例a2，此处不再重复赘述。
在一种可选的实施方式中，所述终端设备在接收到所述指示信息之后，所述终端设备进行小区测量得到N个满足小区质量参数阈值的小区，其中N为大于1的整数，然后对得到的N个小区进行小区测量，并上报测量结果。具体过程可以是：所述终端设备可以进行小区测量选出初始的N个满足小区质量参数阈值的小区，然后对得到的N个小区周期性或者非周期性的以特定方式的进行监测并测量，当发现N个小区中有不满足小区质量参数阈值的小区时，补充相应的不满足的个数以使一直得到N个满足小区质量参数阈值的小区。
在一种可选的实施方式中，所述终端设备进行小区测量选出初始的N个满足小区质量参数阈值的小区，具体方法可以包括以下两种：
方法b1：所述终端设备对当前SSB的频点上的所有邻区进行测量，选择出小区质量参数值最好的N个邻区，从而得到N个满足小区质量参数阈值的小区。
方法b2：所述终端设备对当前SSB的频点上的邻区进行测量，当检测到N个小区质量参数值不小于所述小区质量参数阈值的N个邻区后停止测量，从而得到N个满足小区质量参数阈值的小区。
在所述终端设备通过上述方法得到N个初始的小区之后，所述终端设备对所述N个小区进行监测，进行周期性或非周期性测量，当所述N个小区中的M(M为大于1的整数)个小区不满足所述小区质量参数阈值时，所述终端设备通过以下两种方法补充小区数量：
方法c1：所述终端设备对所述N个小区之外的小区进行测量，得到M个满足所述小区质量参数阈值的小区。这样，可以得到N个满足小区质量参数阈值的小区。
方法c2：所述终端设备对当前SSB的频点上的所有邻区进行测量，得到N个小区质量参数最好且满足所述小区质量参数阈值的小区。在这种方法中，所诉N个小区中只要有不满足所述小区质量参数阈值的小区出现，就会重新测量全部邻区得到N满足小区质量参数阈值的小区。
需要说明的是，在上述方法c1中，当所述终端设备测量所述N个小区之外的小区时，仍然没有满足所述小区质量参数阈值的M个小区时，所述终端设备会采用上述c2中的方法。
在一种实现方式中，可能会出现即使在所述N小区中有不满足所述小区质量参数阈值的小区出现时，所述终端设备先不对其他邻区进行测量，直到所述N个小区中没有满足条件的邻区，或者所述终端设备接收到所述网络设备的指示所述终端设备测量一遍所有邻区，或者设置的测量的定时器(timer)超时，所述终端设备才测量其他邻区进而得到N个满足小区质量参数阈值的小区。
本申请实施例中所涉及的指示信息可以占用一个比特位，当然，指示信息也可以采用其他形式，这里不做具体限定。
在本实施例中，当所述网络设备确定并向所述终端设备下发所述指示信息之前，所述 网络设备可以接收所述终端设备上报的可以支持省电模式的能力信息，或者接收所述终端设备的省电模式请求。
在本实施例中，所述指示信息指示的所述N可以只针对一个SSB的频点，此时所述N可以存在于reportConfig或MO中；所述N还可以被多个频点共用，此时所述N存在于measConfig中。同样的，在本实施例中，当所述指示信息中包含所述小区质量参数阈值时，所述小区质量参数阈值可以是只针对一个SSB的频点，存在于reportConfig或MO中，也可以是被多个频点共用，此时存在于measConfig中。
在本实施例中，所述终端设备在监测所述N个小区时，可以通过接入控制(access control)去判断出现不满足条件的小区。具体的，所述终端设备可以去读所述N个小区的系统消息，如果一个小区被禁止接入(bar)，则表示该小区不满足条件，不再监测该小区(或者在一定时间(通过定时器控制)内不再监测该小区)。
需要说明的是，上述描述的是所述终端设备处于连接态的情况。当所述终端设备处于idle态/inactive时，进行小区重选也需要对邻区进行小区测量，此时，所述网络设备可以通过广播消息向所述终端设备广播指示信息。具体的广播的指示信息的具体描述同样可以参见上述介绍的指示信息，以及所述终端设备根据所述指示信息执行的操作同样可以参见上述介绍的终端设备的行为，此处不再详细介绍。
在一种示例中，所述网络设备可以在所述终端设备由连接(Connected)态进入idle/inactive态时在RRCRelease消息中携带所述指示信息。
采用本申请实施例提供的小区测量方法，终端设备接收来自网络设备的指示信息后，根据所述指示信息进行小区测量，所述指示信息指示所述终端设备进行小区测量得到N个满足小区质量参数阈值的小区。这样所述终端设备无需实时对所述小区都进行测量，可以针对性的只对所述N个小区进行测量，而减少测量的小区数量，从而可以节省所述终端设备的电能，避免资源浪费。
本申请实施例还提供了一种小区测量方法，适用于如图2所示的通信系统。参阅图4所示，该方法的具体流程可以包括：
步骤401：网络设备确定指示信息，所述指示信息用于指示终端设备针对部分邻区进行测量。
步骤402：所述网络设备向所述终端设备发送所述指示信息。
步骤403：所述终端设备根据所述指示信息进行小区测量。
其中，所述网络设备可以通过信令RRCReconfiguration向所述终端设备发送所述指示信息。
在一种可选的实施方式中，所述指示信息可以但不限于体现为以下三种形式：
