Description

一种小区测量方法、装置和*** 技术领域
本申请实施例涉及无线通信领域，尤其涉及一种小区测量方法、装置和***。
背景技术
在新无线电(new radio，NR)独立(stand alone，SA)网络建设初期，NR语音承载(voice over NR，VONR)还没有正式部署，在NR网络中终端设备不能正常运行语音业务。因此，若终端设备在NR网络中需要建立语音业务(例如发起或者接收语音呼叫)，终端设备需要通过演进的分组***回落(evolved packet system fallback，EPS Fallback)的方式回落到长期演进(long term evolution，LTE)网络，由LTE语音承载(voice over lte，VOLTE)来提供语音业务，当语音业务结束后，终端设备再返回到NR网络。
在现有的EPS Fallback技术中，通常采用切换/重定向的方式回落到LTE网络，其大致流程为：网络侧向终端设备下发LTE测量配置信息，终端设备根据接收的测量配置信息进行信号测量，并对获取的LTE小区测量结果进行评估，若有LTE小区的测量结果在一定时间段内持续满足测量上报条件，终端设备才会上报测量报告给网络侧，进而触发网络侧发起切换/重定向流程，从而回落到LTE网络。可见，若终端设备从开始测量信号到上报测量报告的时间较长，会导致EPS Fallback流程时延增加，甚至若测量结果不能满足上报条件而终端设备不上报测量报告，会导致网络侧无法发起切换/重定向，从而导致在此期间语音业务不能正常运行，进而会给用户带来不好的感受和体验。

在VONR还没有正式部署，无法完全由NR SA网络为终端设备提供语音业务的情况下，若终端设备在NR网络中需要建立语音业务(例如发起或者接收语音呼叫)，终端设备需要通过EPS Fallback的方式回落到LTE网络，通过LTE网络中的VOLTE技术来提供语音业务，当语音业务结束后，终端设备再返回到NR网络。
在EPS Fallback场景中，终端设备通常采用切换/重定向的方式回落到LTE网络。目前，触发切换/重定向需要终端设备进行小区测量，包括以下步骤1-步骤5：
步骤1、网络设备向终端设备发送测量配置信息。相应的，终端设备接收来自网络设备的测量配置信息。
一种可能的实现方式中，网络设备通过无线资源控制(radio resource control，RRC)重配置(RRC reconfiguration)消息向终端设备发送预配置的测量配置信息(MeasConfig)，换言之，测量配置信息可以携带在RRC重配置消息中。
测量配置信息包括以下至少一项：待测量的频点/小区信息、上报条件信息等信息。
其中，待测量的频点/小区信息用于指示待测量的小区信息。待测量的频点/小区信息可以仅包括待测量的频点信息，在该情况下，终端设备收到测量配置信息后，可以将待测量的频点信息对应的小区确定为待测量小区。或者，待测量的频点/小区信息可以包括待测量的频点信息以及与待测量的频点对应的待测量的小区信息，在该情况下，终端设备可以根据待测量的小区信息确定待测量小区。示例性的，待测量的小区信息可以为待测量的小区的标识信息。
上报条件信息用于指示测量报告的上报条件，或者说，上报条件信息用于指示终端设备向网络设备发送测量报告的条件。
步骤2、终端设备根据测量配置信息测量待测量小区的信号能量，确定待测量小区的测量结果。
具体地，终端设备根据测量配置信息确定待测量小区后，对待测量小区进行信号测量，得到待测量小区的信号能量，进而确定待测量小区的测量结果。其中，终端设备测量的待测量小区的信号，可以为待测量小区的参考信号。
示例性的，在待测量小区为LTE小区的情况下，该参考信号可以为待测量小区参考信号(cell reference signal，CRS)。
示例性的，在待测量小区为第5代移动通信技术(5th generation mobile communication technology，5G)小区的情况下，该参考信号可以为待测量小区的同步信号块(synchronization signal block，SSB)，待测量小区的信道状态信息参考信号(channel state information reference signal，CSI-RS)等。
示例性的，终端设备测量得到的小区的信号能量包括但不限于以下至少一项：参考信号接收功率(reference signal receiving power，RSRP)值；参考信号接收质量(reference signal receiving quality，RSRQ)值；信号与干扰加噪声比(signal to interference plus noise ratio，SINR)值，接收信号强度指示(received signal strength  indication，RSSI)。
以下以一个具体示例对终端设备如何对待测量小区进行信号测量和确定待测量小区的测量结果进行介绍：
假设测量配置信息指示待测量小区包括小区A和小区B。
终端设备根据测量配置信息启动物理(physical，PHY)层测量小区A的信号能量，终端设备的PHY层向终端设备的RRC层发送小区A的信号能量。终端设备的RRC层根据小区A的信号能量确定小区A的测量结果。
终端设备根据测量配置信息启动PHY层测量小区B的信号能量，终端设备的PHY层向终端设备的RRC层发送小区B的信号能量。终端设备的RRC层根据小区B的信号能量确定小区B的测量结果。
需要说明的是，终端设备根据本次对小区测量得到的信号能量确定测量结果时，可选的，终端设备可以直接将当前测量得到的小区信号能量作为本次小区的测量结果。而如果终端设备并非首次对小区进行测量，可选的，终端设备还可以将前一次测量小区的测量结果(也可以称为小区的历史测量结果)与本次测量得到的小区信号能量进行滤波处理得到本次的测量结果，该实现方式中，测量配置信息还包括用于滤波处理的滤波参数。
示例性的，在终端设备将前一次对小区的测量结果与本次测量得到的小区信号能量进行滤波处理得到本次的测量结果的方式中，终端设备确定的小区的测量结果满足以下公式1：
Y n＝(1-a)×Y n-1+a×X          公式1
其中，Y n为小区的测量结果；Y n-1为终端设备前一次进行小区测量时确定的小区的测量结果(小区的历史测量结果)，X为终端设备本次测量的小区的信号能量，a为滤波参数，取值为常数，示例性的，a的取值为0.5。
其中，终端设备确定小区的历史测量结果的具体实现方式与终端设备确定小区本次的测量结果的方法类似，本申请不再赘述。
步骤3、终端设备根据测量结果，确定测量报告(MeasReport)。
在步骤2中，终端设备确定了各个小区的测量结果，在步骤3中，终端设备(或者说终端设备的RRC层)需要根据测量配置信息中的上报条件信息评估各个小区的测量结果，确定小区的测量结果是否满足上报条件，若满足，则终端设备生成测量报告并向网络设备发送该测量报告。
一种可能的实现方式中，确定测量结果满足上报条件为确定测量结果满足需要上报的测量事件中的一种，生成的测量报告用于向网络设备报告对应的测量事件。
一种示例，需要上报的测量事件包括以下一项或多项：
A1：服务小区(Serving Cell)测量结果高于上报门限1。
A2：服务小区测量结果低于上报门限2。
A3：邻区测量结果高于服务小区测量结果+偏移值(offset)。
A4：邻区测量结果高于上报门限3。
A5：服务小区测量结果低于上报门限4，并且邻区测量结果高于上报门限5。
A6：邻区测量结果高于辅小区(secondary cell，Scell)的测量结果+偏移值(offset)。
B1：异***小区测量结果高于上报门限6。
B2：异***小区测量结果高于上报门限7，服务小区测量结果低于上报门限8。
上述测量事件中，服务小区为终端设备当前接入的小区。邻区为终端设备的服务小区的邻小区。异***小区为所属通信***与终端设备的服务小区所属通信***不同的小区。
终端设备可以根据小区的测量结果以及测量配置信息确定小区测量结果是否满足需要上报的测量事件，若满足某一需要上报的测量事件，则终端设备生成与该事件对应的测量报告。
可以理解的是，需要上报的事件还可以包括其他类型的事件，本申请对此不做限定。
需要说明的是，终端设备可以根据网络设备发送的测量配置信息中的测量标识列表(MeasIdList)，确定需要上报的测量事件以及生成对应的测量报告。其中，MeasIdList包括一个或多个测量标识(MeasId)，每个MeasId用于关联对应的频点/小区信息与需要上报的测量事件。相对应的，终端设备生成的测量报告中包括与测量结果满足的测量事件对应的MeasId，以使网络设备可以根据接收的测量报告中包括的MeasId确定测量报告对应的测量事件。
以下以一个示例对终端设备如何根据测量结果确定测量报告进行说明：假设测量配置信息中，MeasIdList包括的MeasId1关联了频点A和上述测量事件中的B1事件，测量配置信息中的上报条件信息包括上报门限和触发时间(time to trigger，TTT)。其中，上报门限为用于评估测量结果是否满足上报条件的固定阈值，TTT为用于评估测量结果是否满足上报条件的定时器。终端设备收到测量配置信息后，开始对频点A对应的异***小区A进行信号测量并获取小区A的测量结果，若终端设备确定小区A的测量结果高于测量配置信息中包括的上报门限，终端设备启动TTT定时器，若TTT定时器运行期间，终端设备获取的小区A的测量结果持续满足上报门限，则终端设备确定小区A的测量结果满足测量报告的上报条件，终端设备生成与B1事件对应的测量报告。其中，测量报告可以包括MeasId1以及小区A的信息，以使网络设备根据接收的测量报告确定小区A的测量结果满足测量事件B1。
需要说明的是，终端设备生成的测量报告中通常只包括一个需要上报的测量事件。在需要上报的测量事件包括多个，且终端设备确定当前的测量结果同时满足多个需要上报的测量事件的情况下，终端设备为每一个需要上报的测量事件生成对应的测量报告，并逐一向网络设备发送这些测量报告。
步骤4、终端设备向网络设备发送测量报告。相应的，网络设备接收来自终端设备的测量报告。
步骤5、网络设备收到测量报告后，触发相应的切换/重定向流程。
基于上述对于现有技术中小区测量方案的描述可知，如果终端设备进行信号测量和评估测量结果所用的时间较长，不能及时上报测量报告，会导致EPS Fallback流程时延增加，进而导致终端设备建立语音业务的时延增加。甚至若测量结果不能满足上报条件，终端设备无法上报测量报告，而网络侧接收不到测量报告就无法发起切换/重定向，导致EPS Fallback失败，终端设备无法建立语音业务。可见，终端设备能否 及时上报测量报告，会影响到EPS Fallback流程，进而影响终端设备的语音业务以及用户的体验。
而目前的小区测量方案，可能会导致EPS Fallback场景中终端设备无法及时上报测量报告。示例性的，目前的方案中，网络侧并不区分切换/重定向的目的，测量配置信息一旦完成配置后则不会根据终端设备实际的业务类型实时改变。在终端设备获取到的测量配置信息并不适合自身的业务类型的情况下，终端设备仍然会严格按照网侧下发的测量配置信息进行测量并对测量结果进行评估，若测量配置信息里包括的上报条件较严格，可能导致测量结果无法满足上报条件，进而导致终端设备无法发送测量报告。
基于目前的小区测量方案的缺点，本申请提供了一种小区测量方法，用于解决目前EPS Fallback场景中终端设备无法及时上报测量报告的问题。

下面将结合图1至图3，以图1所示的网络设备20与任一终端设备30进行交互为例，对本申请实施例提供的小区测量方法进行展开说明。
如图4所示，为本申请实施例提供的一种小区测量方法，该小区测量方法包括S401-S402：
S401、网络设备向终端设备发送第一消息，相对应的，终端设备接收来自网络设备的第一消息，第一消息包括待测量小区的测量配置信息。
S402、在业务状态为预配置的业务状态的情况下，终端设备向网络设备发送测量报告，相对应的，网络设备接收来自终端设备的测量报告。其中，测量报告是根据测 量配置信息和待测量小区的历史测量结果确定的。
对于S401，本申请实施例中，测量配置信息包括以下至少一项信息：待测量的频点/小区信息和上报条件信息等信息。具体可参考上文介绍，在此不再赘述。
可选的，本申请实施例中，上报条件信息包括以下至少一项：上报门限和TTT等信息。具体可参考上文介绍，在此不再赘述。
需要说明的是，在本申请实施例应用于EPS Fallback场景的情况下，为了终端设备可以回落到LTE网络，待测量的频点/小区信息指示的待测量小区为LTE小区。
一种可能的实现方式中，网络设备可以通过预配置的邻区列表和终端设备当前接入的小区，确定待测量的频点/小区信息。
一种可能的实现方式中，上报条件信息可以是预配置在网络设备中的。
本申请实施例中，第一消息可以为RRC重配置消息，换言之，测量配置信息可以是携带在RRC重配置消息中的。
可选的，本申请实施例中，在S401之前，核心网设备可以向网络设备发送指示消息，该指示消息用于指示网络设备向终端设备发送第一消息。示例性的，若终端设备需要建立语音业务，核心网设备确定终端设备接入的NR网络无法为终端设备提供语音业务，即确定终端设备处于EPS Fallback状态，并向与终端设备连接的网络设备发送通知终端设备处于EPS Fallback状态的指示消息，网络设备收到该指示消息后，向终端设备发送第一消息。
对于S402，终端设备在接收到来自网络设备的测量配置信息后，根据测量配置信息中的待测量的频点/小区信息确定待测量小区，具体可参考上文介绍，在此不再赘述。
本申请实施例中，终端设备可以确定自身的业务状态，若终端设备确定自身的业务状态为预配置的业务状态，终端设备可以在本地存储的小区的历史测量结果中，确定待测量小区的历史测量结果。终端设备确定待测量小区的历史测量结果后，根据测量配置信息对待测量小区的历史测量结果进行评估，确定待测量小区的历史测量结果是否满足测量报告的发送条件，如果满足发送条件，终端设备生成对应的测量报告，并向网络设备发送测量报告。
基于本申请实施例提供的小区测量方法，终端设备在收到测量配置信息后，可以结合待测量小区的历史测量结果确定测量报告，减少了终端设备进行小区测量的时间，可以使终端设备更快速地发送测量报告，进而可以更快速地触发网络设备发起切换/重定向，减少了终端设备回落到LTE网络建立语音业务的时延，可以给用户更好的体验。
需要说明的是，本申请实施例中，测量报告的发送条件也可以称为测量报告的上报条件，在此统一说明，以后不再赘述。
本申请实施例中，待测量小区的历史测量结果可以为终端设备前一次对小区进行信号测量所确定的测量结果，具体可参考上文介绍，在此不再赘述。
本申请实施例中，预配置的业务状态可以根据实际需求配置一种或多种，本申请实施例对此不做限制。可选的，在本申请实施例提供的小区测量方法应用于EPS Fallback场景的情况下，预配置的业务状态包括EPS Fallback状态。
一种可能的实现方式中，本申请实施例中，终端设备确定待测量小区的历史测量 结果是否满足上报条件可以为：终端设备确定待测量小区的历史测量结果是否满足需要上报的测量事件。其中，可选的，终端设备可以根据测量配置信息中的MeasIdList信息，确定需要上报的测量事件。具体可参考上文介绍，在此不再赘述。示例性的，在EPS Fallback场景中，为了回落到LTE网络，需要上报的测量事件可以包括测量事件B1或测量事件B2。
一种可能的实现方式中，本申请实施例中，终端设备根据测量配置信息对待测量小区的历史测量结果进行评估可以为：终端设备根据测量配置信息中的上报条件信息对待测量小区的历史测量结果进行评估。不同于现有方案中，在终端设备获取待测量小区本次的测量结果并确定待测量小区本次的测量结果满足上报门限之后，终端设备才能启动TTT定时器并在TTT定时器运行期间评估获取的待测量小区的测量结果能否持续满足上报门限，该实现方式中，若终端设备确定待测量小区的历史测量结果满足上报门限便可以启动TTT定时器，实现尽快启动评估测量结果，进而确定测量报告。
该实现方式有多种不同的情况，以下以具体的示例进行解释：若上报条件为满足测量事件B1，终端设备根据测量配置信息测量待测量小区，并获取本地存储的待测量小区的历史测量结果，如果待测量小区的历史测量结果满足上报门限，则启动TTT定时器。如果在TTT定时器运行期间，终端设备获取到的待测量小区本次的测量结果持续满足上报门限，则终端设备可以确定该待测量小区的测量结果满足上报条件，在TTT定时器超时后生成对应的测量报告并发送给网络设备。若在TTT定时器运行期间，终端设备获取到的待测量小区本次的测量结果不能满足上报门限，则终端设备不会生成对应的测量报告，以避免若待测量小区当前的信号质量较差，从而导致终端设备切换至该待测量小区后降低了终端设备的业务传输质量。
或者，如果在TTT定时器运行期间，终端设备没有获取到待测量小区本次的测量结果，则终端设备确定待测量小区的历史测量结果满足上报条件，在TTT定时器超时后生成对应的测量报告并发送给网络设备。
本申请实施例中，终端设备生成的测量报告可以包括历史测量结果满足上报条件的待测量小区的信息以及与待测量小区关联的MeasId信息，以使网络设备收到测量报告后，可以根据测量报告中包括的待测量小区的信息，发起切换/重定向流程，具体可参考上文介绍，在此不再赘述。可选的，测量报告还可以包括待测量小区的历史测量结果。
可选的，本申请实施例中，网络设备在接收到来自终端设备的测量报告后，网络设备可以根据测量报告发起切换/重定向流程。
其中，上述步骤S401至S402中终端设备的动作可以由图2所示的终端设备30中的处理器301调用存储器302中存储的应用程序代码以指令终端设备执行；上述步骤S401至S402中网络设备的动作可以由图2所示的网络设备20中的处理器201调用存储器202中存储的应用程序代码以指令网络设备执行。本实施例对此不作任何限制。
如图5所示，为本申请实施例提供的另一种小区测量方法，该小区测量方法包括S501-S502：
S501、网络设备向终端设备发送第一消息，相对应的，终端设备接收来自网络设备的第一消息，第一消息包括待测量小区的测量配置信息。
S502、在业务状态为预配置的业务状态的情况下，终端设备向网络设备发送测量报告，相对应的，网络设备接收来自终端设备的测量报告。其中，测量报告是根据第一测量结果确定的，第一测量结果是终端设备在将待测量小区作为第一优先级的测量任务的情况下，根据测量配置信息对待测量小区进行测量得到的。
对于S501，具体可参考上文对S401的介绍，在此不再赘述。
对于S502，终端设备在接收到来自网络设备的测量配置信息后，根据测量配置信息中的待测量的频点/小区信息确定待测量小区，具体可参考上文介绍，在此不再赘述。
上文介绍的目前终端设备对小区进行信号测量的方案中，终端设备的PHY层可能有多个测量任务，终端设备的PHY层会按照收到测量任务的时间顺序依次处理，且终端设备的PHY层是按照一定的节奏(或者说周期)处理测量任务的。示例性的，若终端设备的PHY层在200ms时测量得到小区A的信号能量，下一个测量任务是小区B，PHY层不会立即测量小区B，而是会在400ms时再对小区B进行信号测量。
为了减少测量待测量小区的时间，本申请实施例中，若终端设备确定自身的业务状态为预配置的业务状态，终端设备可以将待测量小区作为第一优先级的测量任务，优先对待测量小区进行信号测量，并将测量得到的待测量小区的信号能量确定为待测量小区的第一测量结果。该过程也可以称为终端设备对待测量小区进行快速测量。其中，待测量小区作为第一优先级的测量任务可以理解为无论终端设备是否还有测量任务未处理，终端设备均立即处理待测量小区的测量任务。
本申请实施例中，终端设备对小区进行信号测量得到的小区的信号能量，可以为小区的RSRP值，RSRQ值，SINR值中的至少一个。或者，小区的信号能量还可以为其他用于表征信号质量的参数，本申请对此不做限定。
不同于目前的方案中，终端设备按照顺序依次处理测量任务，可能增加用于测量待测量小区的时间，基于本申请实施例提供的小区测量方法，终端设备可以将待测量小区作为第一优先级的测量任务对待测量小区进行快速测量，减少了终端设备进行小区测量的时间，可以使终端设备更快速地发送测量报告，进而可以更快速地触发网络设备发起切换/重定向，减少了终端设备回落到LTE网络建立语音业务的时延，可以给用户更好的体验。
一种可能的实现方式中，本申请实施例中，终端设备获取待测量小区的第一测量结果的具体实现可以为：终端设备的RRC层将待测量小区的信息通知给终端设备的PHY层，并通知PHY层待测量小区为第一优先级的测量任务，终端设备的PHY层收到通知信息后，立即对待测量小区进行信号测量，并在得到待测量小区的信号能量后，立即发送给RRC层。RRC层将得到的待测量小区的信号能量，确定为待测量小区的第一测量结果。
S502中，终端设备如何根据待测量小区的第一测量结果确定测量报告可以参考上文对S402的介绍，在此不再赘述。
可选的，本申请实施例中，网络设备在接收到来自终端设备的测量报告后，网络设备可以根据测量报告发起切换/重定向流程。
其中，上述步骤S501至S502中终端设备的动作可以由图2所示的终端设备30中的处理器301调用存储器302中存储的应用程序代码以指令终端设备执行；上述步 骤S501至S502中网络设备的动作可以由图2所示的网络设备20中的处理器201调用存储器202中存储的应用程序代码以指令网络设备执行。本实施例对此不作任何限制。
一种可能的实现方式中，图4所示的小区测量方法可以与图5所示的小区测量方法结合。该结合后的小区测量方法包括以下步骤：
步骤1：网络设备向终端设备发送第一消息，相对应的，终端设备接收来自网络设备的第一消息，第一消息包括待测量小区的测量配置信息。
步骤2：在业务状态为预配置的业务状态的情况下，终端设备向网络设备发送测量报告，相对应的，网络设备接收来自终端设备的测量报告。
其中，测量报告是根据第一测量结果和待测量小区的历史测量结果确定的；第一测量结果是在将待测量小区作为第一优先级的测量任务的情况下，根据测量配置信息对待测量小区进行测量得到的。
对于步骤1，具体可参考上文对S401的介绍，在此不再赘述。
对于步骤2，终端设备确定终端设备的业务状态为预配置的业务状态后，终端设备如何确定待测量小区的历史测量结果具体可参考上文对S402的介绍，在此不再赘述。终端设备如何确定待测量小区的第一测量结果具体可参考上文对S502的介绍，在此不再赘述。
终端设备确定待测量小区的第一测量结果和历史测量结果后，可以根据预配置的规则、待测量小区的第一测量结果和历史测量结果，确定待测量小区的第二测量结果，并对待测量小区的第二测量结果进行评估处理，确定是否满足测量报告的发送条件，若满足发送条件，终端设备生成测量报告并发送给网络设备。
由于小区的无线信号容易受到其他信号的干扰，而产生快衰落等情况，因此终端设备测量到的小区信号能量可能小于小区的实际信号能量。若因为终端设备测量到的小区信号能量小于小区的实际信号能量而导致终端设备上报测量报告，将会导致网络设备将终端设备切换到信号质量较差的小区，从而降低了终端设备的业务传输质量。基于本申请实施例提供的小区测量方法，可以平衡当前对待测量小区进行快速测量得到的测量结果和待测量小区的历史测量结果，共同确定测量报告，实现在减少用于测量小区的时间的基础上，提高测量报告所反映的小区信号能量的准确度，避免因快衰落的情况引起的终端设备错误生成测量报告的情况。
一种可能的实现方式中，测量配置信息中包括滤波参数。终端设备可以根据滤波参数，对待测量小区的第一测量结果和历史测量结果进行滤波处理，得到待测量小区的第二测量结果，并对待测量小区的第二测量结果进行评估处理，确定测量报告。
示例性的，如图6所示，为EPS Fallback场景中，该实现方式的具体流程图。如图6所示，包括S601-S605。
S601、终端设备发起语音通话，终端设备本地已经存储待测量小区的历史测量结果ResultOld。
S602、终端设备接收来自网络设备的测量配置信息。终端设备识别自身当前的业务状态为EPS Fallback状态，通知物理层执行快速测量。
S603、物理层快速上报测到的待测量小区的测量结果，即第一测量结果ResultNew。
S604、终端设备的RRC层应用测量配置信息中的滤波参数对ResultOld与 ResultNew进行滤波处理，得到最终的测量结果，即第二测量结果ResultEnd。
S605、终端设备的RRC层应用ResultEnd进行后续的评估与确定测量报告。
示例性的，终端设备可以根据以下公式确定待测量小区的第二测量结果：
Y n＝(1-a)×Y n-1+a×X               公式2
其中，Y n为待测量小区的第二测量结果；Y n-1为待测量小区的历史测量结果，X为待测量小区的第一测量结果，a为滤波参数，取值为常数，示例性的，a的取值可以为0.5。
另一种可能的实现方式中，终端设备可以根据预配置的计算规则和/或计算参数，对待测量小区的第一测量结果和历史测量结果进行计算，得到待测量小区的第二测量结果，并对待测量小区的第二测量结果进行评估处理，确定测量报告。
步骤2中，终端设备如何根据待测量小区的第二测量结果确定测量报告可以参考上文对S402的介绍，在此不再赘述。
可选的，本申请实施例中，网络设备在接收到来自终端设备的测量报告后，网络设备可以根据测量报告发起切换/重定向流程。
如图7所示，为本申请实施例提供的另一种小区测量方法，该小区测量方法包括S701-S702：
S701、网络设备向终端设备发送第一消息，相对应的，终端设备接收来自网络设备的第一消息，第一消息包括待测量小区的测量配置信息。
S702、在业务状态为预配置的业务状态的情况下，终端设备向网络设备发送测量报告，相对应的，网络设备接收来自终端设备的测量报告。其中，测量报告是根据第一测量结果和目标参数的值确定的；第一测量结果是根据测量配置信息对待测量小区进行测量得到的；目标参数的值是根据业务状态确定的，目标参数用于确定测量报告的发送条件。
不同于目前的小区测量方案中，用于确定测量报告的发送条件的测量配置信息预配置在网络设备中，无法根据终端设备的业务状态实时调整，基于本申请实施例提供的小区测量方法，可以根据终端设备的业务状态，确定用于确定测量报告的发送条件的目标参数，换言之，测量报告的发送条件可以根据终端设备的业务状态进行调整，避免出现因为发送条件不适合终端设备的业务状态导致终端设备不能及时发送测量报告甚至无法发送测量报告的情况，可以使终端设备更快速地发送测量报告，进而可以更快速地触发网络设备发起切换/重定向，减少了终端设备回落到LTE网络建立语音业务的时延，可以给用户更好的体验。
其中，上述步骤S701至S702中终端设备的动作可以由图2所示的终端设备30中的处理器301调用存储器302中存储的应用程序代码以指令终端设备执行；上述步骤S701至S702中网络设备的动作可以由图2所示的网络设备20中的处理器201调用存储器202中存储的应用程序代码以指令网络设备执行。本实施例对此不作任何限制。
为了更清楚地对图7所示的小区测量方法进行说明，以下分为多个场景展开介绍图7所示的小区测量方法：
场景一：目标参数的值是网络设备确定的。以下结合图8，对场景一中的小区测量方法进行展开介绍。如图8所示，该方案包括S801-S805。
S801、终端设备确定自身的业务状态为预配置的业务状态。
S802、终端设备向网络设备发送第二消息，相对应的，网络设备接收来自终端设备的第二消息。其中，第二消息用于指示终端设备当前的业务状态。
本申请实施例中，第二消息可以为现有的终端设备与网络设备之间交互的信令消息，例如第二消息可以为用户设备辅助信息(UE assistance information)。或者，第二消息也可以为新增的信令消息，本申请实施例对此不做限定。
S803、网络设备根据终端设备的业务状态确定目标参数的值。
可选的，本申请实施例中，目标参数可以包括上报门限和TTT中的至少一项。
以下具体介绍本申请实施例中，网络设备根据终端设备的业务状态确定目标参数的值的方式。
一种可能的实现方式中，网络设备可以根据终端设备的业务状态，在预配置的一个或多个目标参数的值中，确定与终端设备的业务状态对应的目标参数的值。例如，目标参数为上报门限，网络设备预配置上报门限的数值可以为1或2，其中，数值1与业务状态A对应，数值2与业务状态B对应。网络设备接收到终端设备发送的指示终端设备当前处于业务状态A的第二消息，网络设备根据该第二消息，确定上报门限的值为1。
另一种可能的实现方式中，网络设备可以根据终端设备的业务状态以及预配置的规则，确定目标参数的值。示例性的，预配置的规则可以为：对于目标参数x，场景a下，业务状态A对应的目标参数x的值为1，业务状态B对应的目标参数x的值为2。场景b下，业务状态A对应的目标参数x的值为2，业务状态B对应的目标参数x的值为1。
S804、网络设备向终端设备发送目标参数的值，相对应的，终端设备接收来自网络设备的目标参数的值。
本申请实施例中，网络设备可以将目标参数的值携带在测量配置信息中发送给终端设备。换言之，网络设备收到终端设备发送的第二消息后，根据终端设备的业务状态调整测量配置信息中对应的目标参数的数值，使测量配置信息更适用于终端设备的业务状态，再将测量配置信息发送给终端设备。
S805、终端设备根据目标参数的值，对待测量小区的第一测量结果进行评估，确定待测量小区的第一测量结果是否满足测量报告的发送条件，若满足发送条件，终端设备生成测量报告并发送给网络设备。终端设备如何根据待测量小区的第一测量结果确定测量报告可以参考上文对S402的介绍，在此不再赘述。
基于本申请实施例提供的小区测量方法，可以使网络设备根据终端设备的业务状态调整测量配置信息再发送给终端设备，避免出现因为测量报告的发送条件不适合终端设备的业务状态导致终端设备不能及时发送测量报告甚至无法发送测量报告的情况。
场景二：目标参数的值是终端设备确定的。以下结合图9，对场景二中的小区测量方法进行展开介绍。如图9所示，该方案包括S901-S904。
S901、网络设备向终端设备发送测量配置信息，相对应的，终端设备接收到来自网络设备的测量配置信息。其中，测量配置信息包括目标参数的第二数值。
本申请实施例中，网络设备可以将目标参数的第二数值携带在测量配置信息中发 送给终端设备。换言之，终端设备可以根据网络设备发送的测量配置信息确定目标参数的第二数值。
S902、终端设备确定自身的业务状态为预配置的业务状态，终端设备可以根据自身的业务状态，确定目标参数的第一数值。
对于终端设备确定目标参数的第一数值的具体实现，本申请实施例中，一种可能的实现方式中，终端设备可以根据终端设备的业务状态，在预配置的一个或多个目标参数的第一数值中，确定与终端设备的业务状态对应的目标参数的第一数值。例如，目标参数为上报门限，网络设备预配置上报门限的数值(或者说第一数值)可以为1或2，其中，第一数值1与业务状态A对应，第一数值2与业务状态B对应。终端设备确定自身的业务状态为业务状态A后，根据业务状态与第一数值的对应关系，确定上报门限的第一数值为1。
另一种可能的实现方式中，终端设备可以根据终端设备的业务状态以及预配置的规则，确定目标参数的值。示例性的，预配置的规则可以为：对于目标参数x，场景a下，业务状态A对应的目标参数x的第一数值为1，业务状态B对应的目标参数x的第一数值为2。场景b下，业务状态A对应的目标参数x的第一数值为2，业务状态B对应的目标参数x的第一数值为1。
S903、终端设备根据预配置的规则，在目标参数的第一数值和目标参数的第二数值中确定出目标参数的值。
S904、终端设备根据目标参数的值，对待测量小区的第一测量结果进行评估，确定待测量小区的第一测量结果是否满足测量报告的发送条件，若满足发送条件，终端设备生成测量报告并发送给网络设备。
S903中，预配置的规则可以根据实际需求，与预配置的业务状态相对应。示例性的，根据上文介绍可知，在终端处于EPS Fallback业务状态的情况下，为了使尽快终端设备回落LTE网络，需要减少终端设备用于评估测量结果的时间，和/或需要降低终端设备发送测量报告的条件。因此，与EPS Fallback业务状态对应的用于确定目标参数的值的规则可以为：第一数值和第二数值中较小的数值为目标参数的值。
基于本方案，可以从第一数值和第二数值中选择较小的数值作为目标参数的值，从而减少终端设备用于评估测量结果的时间，或者使终端设备发送测量报告的条件更宽松，促使网络设备更快地控制终端设备回落到LTE网络。
为了便于理解，以下以预配置的业务状态为EPS Fallback业务状态，目标参数为上报门限或者TTT的示例，对终端设备确定目标参数的值的方式进行介绍。
示例一：目标参数为上报门限(Thresh参数)。终端设备计算目标参数ThreshEnd的值的流程如图10所示。图10中，ThreshNet为网络设备发送给终端设备的测量配置信息中包括的上报门限，数值为-80dBm，换言之，目标参数的第二数值为-80dBm。ThreshPrivate为终端设备预配置的与EPS Fallback业务状态对应的上报门限，数值为-100dBm，换言之，目标参数的第一数值为-100dBm。终端设备确定自身的业务状态，若自身不处于EPS Fallback业务状态，则终端设备直接将ThreshNet的数值赋值给ThreshEnd。若终端设备确定自身处于EPS Fallback业务状态，则终端设备比较ThreshNet和ThreshPrivate的大小。若ThreshNet小于等于ThreshPrivate，则将ThreshNet 的数值赋值给ThreshEnd，若ThreshNet大于ThreshPrivate，则将ThreshPrivate的数值赋值给ThreshEnd。终端设备经过如图10所示的流程后，最终计算得到ThreshEnd为-100dBm。
终端设备确定ThreshEnd为-100dBm后，可以通过ThreshEnd评估待测量小区的第一测量结果是否满足上报条件。具体地，终端设备获取到待测量小区的信号能量后，如果满足ThreshEnd，换言之大于-100dBm，终端设备启动TTT定时器，若定时器运行期间终端设备获取到的该待测量小区的信号能量均大于-100dBm，则终端设备在定时器超时后上报测量报告给网络设备。基于本方案，终端设备可以以较低的上报门限评估小区的测量结果，只要待测量小区的信号能量可以满足较低的上报门限终端设备就可以触发评估上报流程，从而促使网络设备更快地控制终端设备回落到LTE网络。
示例二：目标参数为触发时间(TTT参数)。终端设备计算目标参数TTTEnd的值的流程如图11所示。图11中，TTTNet为网络设备发送给终端设备的测量配置信息中包括的触发时间，数值为320ms，换言之，目标参数的第二数值为320ms。TTTPrivate为终端设备预配置的与EPS Fallback业务状态对应的触发时间，数值为10ms，换言之，目标参数的第一数值为10ms。终端设备确定自身的业务状态，若自身不处于EPS Fallback业务状态，则终端设备直接将TTTNet的数值赋值给TTTEnd。若终端设备确定自身处于EPS Fallback业务状态，则终端设备比较TTTNet和TTTPrivate的大小。若TTTNet小于等于TTTPrivate，则将TTTNet的数值赋值给TTTEnd，若TTTNet大于TTTPrivate，则将TTTPrivate的数值赋值给TTTEnd。终端设备经过如图11所示的流程后，最终计算得到TTTEnd为10ms。
终端设备确定TTTEnd为10ms后，可以通过TTTEnd评估待测量小区的第一测量结果是否满足上报条件。具体地，终端设备获取到待测量小区的信号能量后，如果满足上报门限，终端设备启动TTTEnd定时器，若定时器运行的10ms期间终端设备获取到的该待测量小区的信号能量均大于上报门限，则终端设备在定时器超时后上报测量报告给网络设备。基于本方案，若待测量小区的信号能量满足上报门限，终端设备在较短时长后，就可以触发评估上报流程，从而促使网络设备更快地控制终端设备回落到LTE网络。
可以理解的是，本申请实施例中，如上述示例一所示的实施例或上述示例二所示的实施例可以独立应用，也可以结合应用，本申请实施例对此不做限制。
一种可能的实现方式中，场景二中目标参数的第二数值，可以是网络设备根据终端设备的业务状态确定的。换言之，场景一中网络设备确定的目标参数的值，可以为场景二中目标参数的第二数值。该方案中，在网络设备向终端设备发送测量配置信息之前(在S701之前)，若终端设备确定自身的业务状态为预配置的业务状态，终端设备向网络设备发送指示终端设备当前业务状态的第二消息，网络设备收到该第二消息后，根据终端设备的业务状态确定目标参数的第二数值并携带在测量配置信息中发送给终端设备，具体可参考上文对场景一的介绍，在此不再赘述。之后终端设备根据目标参数的第一数值和第二数值，进一步确定目标参数的值。具体可参考上文对场景二的介绍，在此不再赘述。
基于本方案，终端设备可以根据网络设备发送的根据终端设备的业务状态调整的 测量配置信息，进一步地确定用于确定测量报告发送条件的目标参数，得到的目标参数的值可以促使网络设备更快地控制终端设备回落到LTE网络。
可选的，本申请实施例中，图5所示的小区测量方法可以与图7所示的小区测量方法结合。
一种可能的实现方式中，在终端设备确定自身的业务状态为预配置的业务状态情况下，终端设备可以根据待测量小区的第一测量结果和目标参数的值确定测量报告。其中，第一测量结果是终端设备将待测量小区作为第一优先级任务进行测量得到的。具体实现可参考上文对图5所示的小区测量方法的说明。目标参数的值是根据终端设备的业务状态确定的，具体实现可参考上文对图7所示的小区测量方法的说明。
进一步地，在终端设备确定自身的业务状态为预配置的业务状态情况下，终端设备可以根据待测量小区的第一测量结果、待测量小区的历史测量结果和目标参数的值确定测量报告。示例性的，终端设备可以根据测量配置信息中的滤波参数，将待测量小区的第一测量结果和待测量小区的历史测量结果进行滤波处理，得到待测量小区的第二测量结果，再根据目标参数的值和第二测量结果确定测量报告。具体实现可参考上文对图4所示的小区测量方法的说明。
基于本方案，可以减少终端设备用于信号测量的时间以及减少终端设备用于评估测量结果和确定测量报告的时间，进而可以更快速地触发网络设备发起切换/重定向，减少了终端设备回落到LTE网络建立语音业务的时延，可以给用户更好的体验。
如图12所示，为本申请实施例提供的又一种小区测量方法，该小区测量方法包括S1201-S1202：

S1202、网络设备向终端设备发送第一消息，相对应的，终端设备接收来自网络设备的第一消息。其中，第一消息包括测量配置信息，测量配置信息是网络设备根据终端设备的业务状态确定的。
对于S1201，终端设备确定自身处于EPS Fallback状态后，向网络设备发送指示终端设备的业务状态为EPS Fallback状态的第三消息。网络设备接收来自终端设备的第三消息后，可以根据第三消息确定终端设备当前处于EPS Fallback状态。具体可以参考上文对S802的介绍，在此不再赘述。
对于S1202，网络设备根据终端设备的业务状态确定测量配置信息，并将确定的测量配置信息携带在第一消息中发送给终端设备。示例性的，网络设备可以根据终端设备的业务状态调整测量配置信息中的上报条件信息。具体可以参考上文对S803的介绍，在此不再赘述。
基于本申请实施例提供的小区测量方法，可以使网络设备确定终端设备处于EPS Fallback状态，并根据终端设备的业务状态确定测量配置信息，可以使测量配置信息更适合终端设备的业务状态，避免出现测量配置信息不适合终端设备当前业务状态的情况。
