  • the cell reselection is an important technology in the wireless communication technology, and its main purpose is to ensure that the UE (User Equipment) in the idle (Idle) state resides in a suitable cell by cell reselection.
  • the process of performing cell reselection by the UE may include: after the UE is in the Idle state and camped on the serving cell, perform measurement on the serving cell and the neighboring cell, and determine the serving cell or If the cell is a serving cell, the UE continues to camp on the serving cell. If the cell is a neighboring cell, the UE reselects to the neighboring cell.
  • the UE needs to measure both the serving cell and the neighboring cell. Specifically, the UE periodically measures the reference signal received power (RSRP, Reference Signal Received Power) of the serving cell and the reference signal receiving quality ( RSRQ, Reference Signal Received Quality), and the measurement of the neighboring cell requires certain conditions to trigger.
  • the neighboring cell may be an intra-frequency neighboring cell and an inter-frequency neighboring cell.

Description

一种邻小区测量的启动方法以及用户设备 技术领域
本发明涉及移动通信技术领域，特别涉及一种邻小区测量的启动方法以及用户设备。
背景技术
小区重选是无线通信技术中的重要技术，其主要目的是保证空闲(Idle)状态下的UE(User Equipment)通过小区重选驻留在合适的小区中。现有长期演进(Long Term Evolution，LTE)系统中，UE进行小区重选的过程可以包括：当UE处于Idle状态且驻留在服务小区之后，对服务小区和邻小区进行测量，确定服务小区或邻小区中信号更好小区，若该小区为服务小区，则UE继续驻留在服务小区，若该小区为邻小区，则UE重选到邻小区。
进一步地，为了实现小区重选，UE需要对服务小区和邻小区均进行测量，具体地，UE会周期性测量服务小区的参考信号接收功率(RSRP，Reference Signal Received Power)和参考信号接收质量(RSRQ，Reference Signal Received Quality)，而对邻小区的测量需要一定的条件进行触发。邻小区可以为同频邻小区和异频邻小区，针对同频邻小区，触发UE对同频邻小区进行测量的条件通常可以为：根据服务小区的RSRP按照S准则的公式计算得到服务小区的小区选择接收电平值Srxlev，根据服务小区的RSRQ按照S准则的公式计算得到服务小区的小区选择接收电平值Squal，如果服务小区满足Srxlev>SIntraSearchP并且Squal>SIntraSearchQ,则可以不对同频邻小区进行测量，否则触发对同频邻小区进行测量；针对异频邻小区，对高优先级的异频邻小区总是要测量，对同优先级和低优先级的异频邻小区，判断服务小区是否满足Srxlev>SnonIntraSearchP并且Squal>SnonIntraSearchQ。若是，则可以不对异频邻小区进行测量，否则触发对异频邻小区进行测量。根据对邻小区的测量结果，确定是否需要进行小区重选。
可见，不论是针对同频邻小区还是异频邻小区，均通过设置阈值确定对 邻小区测量的触发条件，那么，如果阈值设置过高，会导致UE频繁进行邻小区测量，导致UE功耗大，如果阈值设置过低，不触发UE对邻小区的测量，导致UE长期停留在信号差的小区中，对邻小区进行测量的启动方式不合理。

具体实施方式
本发明实施例提供了一种邻小区测量的启动方法以及用户设备，以下结合说明书附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。并且在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
本发明实施例提供一种邻小区测量的启动方法，如图1所示，包括：
S101、判断用户设备对所驻留的服务小区进行同步是否成功。
S102、如果S101中同步成功，则确定用户设备在服务小区内的信号质量参数值。
S103、判断S102中确定的信号质量参数值是否满足预设邻小区测量启动条件。
S104、如果S103中确定的信号质量参数值满足预设邻小区测量启动条件，则启动用户设备对邻小区进行测量。
S105、如果S101中同步失败，则启动用户设备对邻小区进行测量。
进一步地，本发明实施例中邻小区包括同步邻小区和异步邻小区。
下面结合附图，用具体实施例对本发明提供的方法及相关设备进行详细描述。
本发明的一个实施例中，提供一种邻小区测量的启动方法，如图2所示， 具体包括如下步骤：
S201、判断用户设备对所驻留的服务小区进行同步是否成功，若否，则进入步骤S202，若是，则进入步骤S203。
进一步地，本发明实施例可以应用于非连续的接收(DRX，Discontinuous Reception)的场景中，每次用户设备从休眠状态醒来时与服务小区的同步。并且存在以下场景：当服务小区的测量周期设置的较长时，用户设备休眠到醒来的过程中，可能移动到服务小区的边缘，由于信号不好，可能导致用户设备醒来时与服务小区同步失败，如果按照现有技术提供的邻小区测量触发方法，同步失败的用户设备无法测量到参考信号的接收功率，那么更无法触发对邻小区进行测量，使得用户设备不能及时接入信号更好的邻小区，而本发明实施例提供的邻小区测量启动方法，邻小区测量的启动条件包括用户设备与服务小区同步失败，对于上述的场景用户设备能够及时接入信号更好的邻小区，邻小区测量的启动条件更加合理。
S202、启动用户设备对邻小区进行测量。本流程结束。
S203、测量用户设备接收预设信号的接收功率或接收质量，
其中，预设信号可以包括：参考信号、预设信道上的预设序列、或者预设信道上的预设符号。
进一步地，预设信道、预设信道上的预设序列、预设信道上的预设符号可以根据实际情况进行设置，例如，预设信道可以为物理广播同步信道(PBSCH，Physical Broadcast Synchronization Channel)，那么，预设信道上的预设符号可以为主同步信号(PSS，Primary Synchronization Signal)或者辅同步信号(SSS，Secondary Synchronization Signal)。
S204、判断S203中测量的预设信号的接收功率或接收质量是否小于等于该预设信号对应的第一接收阈值；或者
判断对S203中测量的预设信号的接收功率或接收质量进行预设运算后得到的值是否小于等于该预设信号对应的第一运算阈值，若是，进入步骤S202，若否，进入步骤S205。
进一步地，每种预设信号都可以测量接收功率或接收质量，并且针对每种预设信号的接收功率或接收质量，都可以设置该预设信号对应的第一接收阈值，当测量预设信号的接收功率时，第一接收阈值为与预设信号的接收功率对应的阈值，当测量预设信号的接收质量时，第一接收阈值为与预设信号的接收质量对应的阈值。
进一步地，还可以对测量的预设信号的接收功率或接收质量进行预设运算，并为预设信号对应的对该预设信号的接收功率或接收质量进行的预设运算得到的值设置第一运算阈值，当对预设信号的接收功率进行预设运算时，第一运算阈值为与对预设信号的接收功率进行预设运算对应的阈值，当对预设信号的接收质量进行预设运算时，第一运算阈值为与对预设信号的接收质量进行预设运算对应的阈值。
进一步地，预设运算可以根据实际需要进行设置，例如：S准则计算公式，或者S准则计算公式的变形等。
S205、接收系统消息。
S206、对S205中接收的系统消息进行解析。
进一步地，本步骤中，用户设备在与服务小区进行同步之后，可能会接收到系统消息也可能接收不到系统消息，当接收到系统消息时，则对系统消息进行解析。
S207、判断S206中是否成功解析系统消息，若是，进入步骤S208，若否，进入步骤S202。
进一步地，用户设备所在的通信系统针对系统消息可以设置预设系统消息最大接收次数，也就是说，为了防止用户设备接收不到系统消息，系统可以按照该预设系统消息最大接收次数向用户设备发送系统消息，那么，本步骤中，对系统消息解析失败，可以具体实施为：针对按照预设系统消息最大接收次数接收的各系统消息，确认对每个接收的系统消息均解析失败。
进一步地，当未接收到系统消息时，可以不执行步骤S205～步骤S207。
S208、接收寻呼消息。
S209、对S208中接收的寻呼消息进行解析。
进一步地，本步骤中，用户设备在与服务小区进行同步之后，可能会接收到寻呼消息也可能接收不到寻呼消息，当接收到寻呼消息时，则对寻呼消息进行解析。
S210、判断S209中是否成功解析寻呼消息，若是，进入步骤S211，若否，进入步骤S202。
进一步地，网络侧(例如：基站)可以按照预设发送规则(例如：按照周期性规则)发送下行控制消息(DCI，Downlink Control Information)，DCI包含对上行数据、下行数据和随机接入的调度信息，即DCI可以用来分配上行数据资源和下行数据资源和随机接入资源。在用户设备同步成功之后，可以先接收DCI，对DCI进行解析得到寻呼消息的调度指示，并根据解析得到的调度指示接收并解析寻呼消息，如果解析DCI失败，则无法得到寻呼消息的调度指示，那么，无法接收到寻呼消息更无法成功解析寻呼消息。
因此，对寻呼消息进行解析可以理解为：对调度寻呼消息的DCI进行解析，以及对调度寻呼消息的DCI进行解析成功之后，对寻呼消息本身进行解析，并且用户设备所在的通信系统针对寻呼消息可以设置预设寻呼消息最大接收次数，也就是说，为了防止用户设备接收不到寻呼消息，系统可以按照该预设寻呼消息最大接收次数向用户设备发送DCI和寻呼消息，那么，本步骤中，对寻呼消息解析失败，可以具体实施为：针对按照预设寻呼消息最大接收次数接收的各DCI，确认对每个接收的DCI均解析失败，其中，DCI用于调度寻呼消息；或者
针对按照预设寻呼消息最大接收次数接收的各寻呼消息，确认对每个接收的寻呼消息均解析失败。
S211、判断S208中接收的寻呼消息是否为针对用户设备的寻呼消息，且满足S203中测量的预设信号的接收功率或接收质量小于等于预设信号对应的第二接收阈值；或者满足对S203中测量的预设信号的接收功率或接收质量进行预设运算后得到的值小于等于预设信号对应的第二运算阈值，若是，进入 步骤S202，若否，本流程结束。
其中，第二接收阈值大于第一接收阈值，第二运算阈值大于第一运算阈值。
因此，预设信号对应的第一接收阈值可以设的很低，当测量的预设信号的接收功率或接收质量大于第一接收阈值时，不启动邻区测量，也就是说，当用户设备不需要进行数据传输时，不轻易启动对邻小区进行测量，以免对邻小区测量太频繁用户设备功耗大，而是通过第二接收阈值保证当有数据进行传输时，用户设备能够位于更好的小区，也就是说，当用户设备解析到寻呼消息是针对用户设备自己的时，可以认为用户设备需要进行数据传输了，那么比对测量的预设信号的接收功率或接收质量与第二接收阈值，当测量的预设信号的接收功率或接收质量小于或者等于第二接收阈值时，启动对邻小区的测量。当按照对测量的预设信号的接收功率或接收质量进行预设运算后得到的值与第一运算阈值或第二运算阈值进行比对时同理，这里不再赘述。
进一步地，当未接收到寻呼消息时，可以不执行步骤S208～步骤S211。
进一步地，步骤S205～步骤S207的执行，与步骤S208～步骤S211的执行没有严格的先后顺序。
进一步地，本发明提供的邻小区测量的启动方法，几个触发条件协同工作，弥补了门限值设置不合理或测量值不准确时，触发邻小区测量频繁，导致用户设备功耗大，或者无法启动对邻小区测量，导致用户设备长期停留在信号差的小区。
本发明又一实施例中，提供一种邻小区测量的启动方法，可以应用于机器和机器/人直接通信(M2M，Machine to Machine/Man)系统。
进一步地，M2M系统是一种以机器用户设备智能交互为核心的、网络化的应用与服务。M2M系统由数量巨大的M2M设备构成，M2M技术提供了M2M设备实时地在系统之间、远程设备之间、或/和个人之间建立无线连接，传输数据的手段。它通过在M2M设备内部嵌入无线通信模块，实现对机器的监控、指挥调度、数据采集和测量等等。窄带(Narrow Band)M2M系统的应用场景 非常多，比如应用于智能抄表系统、环境监测、远程监控等等。Narrow Band M2M设备多是比较小巧、电池供电的系统。
进一步地，由于某些特殊的M2M设备(例如：传感器、电表、水表、报警装置等)部署的位置可能位于地下室、角落等覆盖很差的区域(据预测，到2022年，这种覆盖类型的用户设备的数量会达到15.5亿)，为了使这些位于覆盖很差的区域的M2M设备能够成功的使用M2M系统，M2M系统的网络覆盖需要比普通的蜂窝网络要好，因此M2M系统的网络覆盖需要增强20dB。
为了满足覆盖增强20dB的要求，可以设计多个不同的覆盖等级，假设划分三个覆盖等级，coverageclass0表示正常覆盖，coverageclass1和coverageclass2被称为覆盖增强场景。覆盖等级越高表示覆盖越差，则可以采用越高的扩频因子和重复次数。例如，coverageclass0不需要扩频和重复，coverageclass1需要重复，但重复次数少于coverageclass2需要的重复次数。可见，在M2M系统中，若使用现有技术提供的邻小区测量触发方式，阈值设置的不合理会使用户设备资源消耗大的问题更加严重。
本发明又一实施例提供的一种邻小区测量的启动方法，如图3所示，具体包括如下步骤：
S301、判断用户设备对所驻留的服务小区进行同步是否成功，若否，则进入步骤S302，若是，则进入步骤S303。
S302、启动用户设备对邻小区进行测量。本流程结束。
S303、确定用户设备在服务小区内所属的覆盖等级。
进一步地，用户设备在初次接入网络时可以根据所测的信号接收电平值选择初始的覆盖等级，在接入网络之后可以根据一定的准则调整覆盖等级。不同的覆盖等级，表明当前小区不同的信号质量。但是每个覆盖等级对应的解调门限可以是变化的且不同的，因此小区重选时用门限值作为小区重选测量的启动条件不能直接反应覆盖等级，因此可将覆盖等级作为小区重选测量的判定条件。
S304、判断S303中确定的覆盖等级是否为信号强度最差覆盖等级，其中， 信号强度最差覆盖等级所表征的信号强度为所有覆盖等级分别对应的信号强度中的最差信号强度；若是，则进入步骤S302，若否，进入步骤S305。
进一步地，按照本实施例中假设的对覆盖等级的划分方法，即假设划分三个覆盖等级，coverageclass0表示正常覆盖，coverageclass1和coverageclass2被称为覆盖增强场景，本步骤中，当S303中确定的覆盖等级为coverageclass2时，启动用户设备对邻小区进行测量。
S305、接收系统消息。
S306、对S305中接收的系统消息进行解析。
进一步地，本步骤中，用户设备在与服务小区进行同步之后，可能会接收到系统消息也可能接收不到系统消息，当接收到系统消息时，则对系统消息进行解析。
S307、判断S306中是否成功解析系统消息，若是，进入步骤S308，若否，进入步骤S302。
进一步地，用户设备所在的通信系统针对不同的覆盖等级，可以为系统消息设置不同的预设系统消息最大接收次数，也就是说，覆盖等级表征的信号强度越差，为该覆盖等级设置的预设系统消息最大接收次数越多，那么，本步骤中，对系统消息解析失败，可以具体实施为：针对按照与用户设备所在覆盖等级对应的预设系统消息最大接收次数接收的各系统消息，确认对每个系统消息均解析失败。
进一步地，当未接收到系统消息时，可以不执行步骤S305～步骤S307。
S308、接收寻呼消息。
S309、对S308中接收的寻呼消息进行解析。
进一步地，本步骤中，用户设备在与服务小区进行同步之后，可能会接收到寻呼消息也可能接收不到寻呼消息，当接收到寻呼消息时，则对寻呼消息进行解析。
S310、判断S309中是否成功解析寻呼消息，若是，进入步骤S311，若否，进入步骤S302。
进一步地，对寻呼消息进行解析可以理解为：对调度寻呼消息的DCI进行解析，以及对调度寻呼消息的DCI进行解析成功之后，对寻呼消息本身进行解析，用户设备所在的通信系统针对不同的覆盖等级，可以为寻呼消息设置不同的预设寻呼消息最大接收次数，也就是说，覆盖等级表征的信号强度越差，为该覆盖等级设置的预设寻呼消息最大接收次数越多，那么，本步骤中，对寻呼消息解析失败，可以具体实施为：针对按照与用户设备所在覆盖等级对应的预设寻呼消息最大接收次数接收的各DCI，确认对每个接收的DCI均解析失败，其中，DCI用于调度寻呼消息，或者
针对按照与用户设备所在覆盖等级对应的预设寻呼消息最大接收次数接收的各寻呼消息，确认对每个接收的寻呼消息均解析失败。
S311、判断S308中接收的寻呼消息是否为针对用户设备的寻呼消息，且S303中确定的覆盖等级是否为中间覆盖等级，其中，中间覆盖等级所表征的信号强度为所有覆盖等级分别对应的信号强度中，除最差的信号强度以及最好的信号强度之外的信号强度，若是，则进入步骤S302，若否，本流程结束。
进一步地，按照本实施例中假设的对覆盖等级的划分方法，即假设划分三个覆盖等级，coverageclass0表示正常覆盖，coverageclass1和coverageclass2被称为覆盖增强场景，本步骤中，当S307中接收的寻呼消息为针对用户设备的寻呼消息，且S303中确定的覆盖等级为coverageclass1时，启动用户设备对邻小区进行测量。
进一步地，当未接收到寻呼消息时，可以不执行步骤S308～步骤S311。
进一步地，步骤S305～步骤S307的执行，与步骤S308～步骤S311的执行没有严格的先后顺序。
本发明再一实施例中，提供一种邻小区测量的启动方法，本发明再一实施例提供的一种邻小区测量的启动方法可以应用于M2M系统，如图4所示，具体包括如下步骤：
S401、判断用户设备对所驻留的服务小区进行同步是否成功，若否，则进入步骤S402，若是，则进入步骤S403。
S402、启动用户设备对邻小区进行测量。本流程结束。
S403、确定用户设备在服务小区内所属的覆盖等级。
S404、判断S403中确定的覆盖等级是否为中间覆盖等级，其中，中间覆盖等级所表征的信号强度为所有覆盖等级分别对应的信号强度中，除最差的信号强度以及最好的信号强度之外的信号强度，若是，则进入步骤S402，若否，进入步骤S405。
与本发明上述又一实施例相比，本步骤中，启动对邻小区进行测量的条件更加严格，也就是说，按照本发明上述又一实施例中假设的对覆盖等级的划分方法，用户设备在服务小区内所属的覆盖等级为coverageclass1时就启动对邻小区进行测量。
进一步地，本步骤中还可以采用相对阈值来启动邻小区测量，也就是说，当用户设备进行小区选择时，选择了一个最好的小区驻留，该小区反应了信号最好的小区。如果用户设备所属的覆盖等级变差，则用户设备启动邻小区测量，如果用户设备所属的覆盖等级没有变化，即使用户设备在最差的覆盖等级，也不进行邻小区的测量，因为，即使进行邻小区测量，也找不到信号更好的小区。
进一步地，本步骤还可以实施为：判断S403中确定的覆盖等级表征的信号强度，与用户设备最近一次确定出的所属的覆盖等级表征的信号强度相比，是否信号强度变差；若是，则进入步骤S402，若否，进入步骤S405。
例如，按照本发明上述又一实施例中假设的对覆盖等级的划分方法，即假设划分三个覆盖等级，coverageclass0表示正常覆盖，coverageclass1和coverageclass2被称为覆盖增强场景，用户设备进行小区选择时所驻留的小区覆盖等级为coverageclass0，若检测到用户设备所属覆盖等级变为coverageclass1，则启动用户设备对邻小区进行测量；或者，若用户设备进行小区选择时所驻留的小区覆盖等级为coverageclass1，若检测到用户设备所属覆盖等级变为coverageclass2，则启动用户设备对邻小区进行测量。
可选的，为了保证用户设备能驻留到最好的小区，可以配置用户设备每 隔一段时间进行扫频，选择各个频段最好的小区进行驻留。
S405、接收系统消息。
S406、对S405中接收的系统消息进行解析。
进一步地，本步骤中，用户设备在与服务小区进行同步之后，可能会接收到系统消息也可能接收不到系统消息，当接收到系统消息时，则对系统消息进行解析。
S407、判断S406中是否成功解析系统消息，若是，进入步骤S408，若否，进入步骤S402。
进一步地，本步骤中，系统消息解码失败可以进一步实施为：在S403中确定的覆盖等级为信号强度最差覆盖等级，且用户设备在该覆盖等级下解析系统消息失败。
进一步地，当未接收到系统消息时，可以不执行步骤S405～步骤S407。
S408、接收寻呼消息。
S409、对S408中接收的寻呼消息进行解析。
进一步地，本步骤中，用户设备在与服务小区进行同步之后，可能会接收到寻呼消息也可能接收不到寻呼消息，当接收到寻呼消息时，则对寻呼消息进行解析。
S410、判断S409中是否成功解析寻呼消息，若是，本流程结束，若否，进入步骤S402。
进一步地，对寻呼消息进行解析可以理解为：对调度寻呼消息的DCI进行解析，以及对调度寻呼消息的DCI进行解析成功之后，对寻呼消息本身进行解析，对所述寻呼消息解析失败，可以具体实施为：
在S403中确定的覆盖等级为最差信号强度覆盖等级，且用户设备在该覆盖等级下解析调度寻呼消息的DCI失败，或者
在S403中确定的覆盖等级为最差信号强度覆盖等级，且用户设备在该覆盖等级下解析寻呼消息失败。
进一步地，当未接收到寻呼消息时，可以不执行步骤S408～步骤S410。
进一步地，步骤S405～步骤S407的执行，与步骤S408～步骤S410的执行没有严格的先后顺序。
