Description

本申请涉及移动通信技术领域，尤其涉及一种小区的测量方法以及相关装置。
背景技术
随着移动通信技术的不断发展，新无线(New Radio，NR)移动通信技术的覆盖范围正在逐步扩大。通信网络中存在长期演进(Long Term Evolution，LTE)技术和NR技术共存的情况。
在一些应用场景中，在同一频段上，相邻的两个小区可能支持不同的制式。在LTE、NR通信系统中，都是通过同一通信制式内的同频测量和切换，保障移动终端能够始终处于同一通信制式内的最强信号的小区上，终端设备无法进行无额外功耗的跨制式的同频测量。
在邻近的异制式同频小区发送的邻区信号强于的服务小区提供的服务信号的情况下，邻区信号会对终端设备接收到的服务信号造成较强干扰；另外，为了确保服务小区能正常接收到终端设备发送的上行信号，终端设备会增大自身发射信号的功率，这样会使得终端设备发送的上行信号干扰服务小区中其他终端设备发送的上行信号。上述这种情况称为远近干扰，如何避免终端设备在同频异制式组网中的远近干扰的问题是本领域技术人员亟待解决的问题。

具体实施方式
下面对本申请实施例中的技术方案进行更详细地描述。
本申请以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”“一种”“所述”“上述”“该”和“这一”旨在也包括复数表达形式，除非其上下文中明确地有相反指示。还应当理解，本申请中使用的术语“和/或”是指并包含一个或多个所列出项目的任何或所有可能组合。
还应理解，本文中涉及的第一、第二、第三、第四以及各种数字编号仅为描述方便进行的区分，并不用来限制本申请实施例的范围。
本申请实施例可以应用于图1A所示的网络架构，图1A所示的网络架构为无线通信系统的网络架构，该网络架构通常包括终端设备和接入网设备，各个设备数量以及形态并不构成对本申请实施例的限定。在图1A中，包含接入网设备1、接入网设备2和一个或者多个终端设备(图中以终端设备1、终端设备2作为示例，终端设备1驻扎在LTE小区1，终端设备2驻扎在NR小区1)。具体的，LTE小区1与接入网设备1对应，可以理解为，接入网设备1提供LTE小区1，并通过LTE小区1为终端设备1提供通信服务。NR小区1和与接入网设备2对应，可以理解为，接入网设备2提供NR小区1，并通过NR小区1为终端设备2提供通信服务。其中，图1A中的虚线表示小区的覆盖范围，以下图示中相同标注可以参考该说明。LTE小区为采用LTE的通信制式的小区，NR小区为采用NR的通信制式的小区。该LTE小区1和该NR小区1的频率范围有重叠。
在图1A所示的系统中，接入网设备1可以通过LTE小区1向驻扎在LTE小区1中的一个或者多个终端设备(示例为终端设备1)发送信号，接入网设备2可以通过NR小区1向驻扎在NR小区1中的一个或者多个终端设备(示例为终端设备2)发送信号。在接入网设备2通过NR小区1向终端设备2发送信号时，终端设备1可能会接收到接入网设备2发送的信号，该信号对终端设备1与接入网设备1之间的通信造成干扰，从而该信号可以认为是干扰信号。另外，为了确保接入网设备1能正常接收到终端设备1发送的上行信号，终端设备1会增大自身发射信号的功率，这样会使得终端设备发送的上行信号干扰接入LTE小区1中其他终端设备发送的上行信号。
参见图1B，是本申请实施例提供的又一种网络架构的示意图。在图1B中，包含接入网设备4、接入网设备5和一个或者多个终端设备(图中以终端设备6、终端设备5作为示例，终端设备6驻扎在LTE小区6，终端设备5驻扎在LTE小区7)。具体的，LTE小区6与接入网设备4对应，可以理解为，接入网设备4提供LTE小区6，并通过LTE小区6为终端设备6提供通信服务。LTE小区7和与接入网设备5对应，可以理解为，接入网设备5提供LTE小区7，并通过LTE小区7为终端设备5提供通信服务。可选的，LTE小区6与LTE小区7为相同制式的小区，但是LTE小区6与LTE小区7的下行参考信号的中心 频点不相同，且LTE小区6与LTE小区7的频率范围有重叠。举例而言，LTE小区6的频率范围为2010MHz～2020MHz，其下行参考信号的中心频点为2015MHz；LTE小区7的频率范围为2010MHz～2040MHz，其下行参考信号的中心频点为2020MHz。需要说明的是，在本申请实施例中，制式相同但是下行参考信号的中心频点不同的小区，可以称为同制式异频小区；也即是说，LTE小区6与LTE小区7为同制式异频小区。下行参考信号的中心频点相同的两个小区可以称为同频小区。
在图1B所示的系统中，接入网设备4可以通过LTE小区6向驻扎在LTE小区6中的一个或者多个终端设备(示例为终端设备6)发送信号，接入网设备5可以通过LTE小区7向驻扎在LTE小区7中的一个或者多个终端设备(示例为终端设备5)发送信号。在接入网设备5通过LTE小区7向终端设备5发送信号时，由于LTE小区6与LTE小区7的频率范围有重叠，终端设备6可能会接收到接入网设备5发送的信号，该信号对终端设备6与接入网设备4之间的通信造成干扰，从而该信号可以认为是干扰信号。另外，为了确保接入网设备4能正常接收到终端设备6发送的上行信号，终端设备6会增大自身发射信号的功率，这样会使得终端设备发送的上行信号干扰接入LTE小区6中其他终端设备发送的上行信号。在另一些实施例中，接入网设备5提供两个的小区也可以均为NR小区，这两个NR小区为同制式异频小区。这种情况下，终端设备6所受到远近干扰的形成方式可以参照上述介绍的方式，此处不再赘述。
参见图2A，是本申请实施例提供的又一种网络架构的示意图。在图2A中，包含接入网设备3和一个或者多个终端设备(图中以终端设备3、终端设备4作为示例，终端设备3驻扎在LTE小区2，终端设备4驻扎在NR小区2)。具体的，LTE小区2与接入网设备3对应，可以理解为，接入网设备3提供LTE小区2，并通过LTE小区2为终端设备3提供通信服务。NR小区2和与接入网设备3对应，可以理解为，接入网设备3提供NR小区2，并通过NR小区2为终端设备4提供通信服务。
在图2A所示的系统中，接入网设备3可以通过LTE小区2向驻扎在LTE小区2中的一个或者多个终端设备(示例为终端设备3)发送信号，接入网设备3可以通过NR小区2向驻扎在NR小区2中的一个或者多个终端设备(示例为终端设备4)发送信号。在接入网设备3通过NR小区2向终端设备4发送信号时，终端设备3可能会接收到接入网设备3发送的信号，该信号对终端设备3与接入网设备3之间的通过LTE小区2的通信造成干扰，从而该信号可以认为是干扰信号。另外，为了确保接入网设备3能正常接收到终端设备3发送的上行信号，终端设备3会增大自身发射信号的功率，这样会使得终端设备发送的上行信号干扰接入LTE小区2中其他终端设备发送的上行信号。
参见图2B，是本申请实施例提供的又一种网络架构的示意图。在图2B中，包含接入网设备6和一个或者多个终端设备(图中以终端设备7、终端设备8作为示例，终端设备7驻扎在NR小区3，终端设备8驻扎在NR小区4)。具体的，NR小区3与接入网设备7对应，可以理解为，接入网设备6提供NR小区3，并通过NR小区3为终端设备7提供通信服务。NR小区4和与接入网设备6对应，可以理解为，接入网设备6提供NR小区4，并通过NR小区4为终端设备8提供通信服务。其中，NR小区3和NR小区4为相同制式的小区，但是NR小区3和NR小区4的下行参考信号的中心频点不相同，且NR小区3和 NR小区4的频率范围有重叠。NR小区3和NR小区4为同制式异频小区。
在图2B所示的系统中，接入网设备6可以通过NR小区3向驻扎在NR小区3中的一个或者多个终端设备(示例为终端设备7)发送信号，接入网设备6可以通过NR小区4向驻扎在NR小区4中的一个或者多个终端设备(示例为终端设备8)发送信号。在接入网设备6通过NR小区4向终端设备8发送信号时，终端设备7可能会接收到接入网设备6发送的信号，该信号对终端设备7与接入网设备6之间的通过NR小区3的通信造成干扰，从而该信号可以认为是干扰信号。另外，为了确保接入网设备6能正常接收到终端设备7发送的上行信号，终端设备7会增大自身发射信号的功率，这样会使得终端设备发送的上行信号干扰接入NR小区3中其他终端设备发送的上行信号。
在另一些实施例中，接入网设备6提供两个的小区也可以均为LTE小区，这两个LTE小区为同制式异频小区。这种情况下，终端设备7所受到远近干扰的形成方式可以参照上述介绍的方式，此处不再赘述。

以下对本申请实施例涉及到的一些概念进行介绍。
通信制式(或者简称为制式)，是移动终端进行数据通信所采用的网络标准。比如，对于第二代移动通信技术(the 2nd generation mobile communication technology，2G)而言，通信制式包括GSM，CDMA。对于3G第三代移动通信技术(the 3rd generation mobile communication technology，3G)而言，通信制式包括时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)，WCDMA，CDMA2000(Code Division Multiple Access 2000)。对于第四代移动通信技术(the 4th generation mobile communication technology，4G)而言，通信制式包括时分双工长期演进(LongTermEvolution，Time-DivisionDuplex，LTE-TDD)和频分双工长期演进(LongTermEvolution，Frequency-division duplex，LTE-FDD)两种制式，其中LTE-TDD又称为TD-LTE。对于第五代移动通信技术(the 5th generation mobile communication technology，5G)而言，通信制式包括非独立组网(NSA)和独立组网(SA)。在本申请实施例中，在同一频段上，相邻的两个小区可能支持不同的通信制式。
在移动通信的演进过程中，示例性的，从4G演进到5G的过程中，通信系统中常出现LTE和NR同频组网的情况。以下对几种常见的网络架构进行介绍。
参见图3，是本申请实施例提供的又一种网络架构的示意图。可以对应于图1A和图2A在图3所示区域范围内包含多个通信小区，这些通信小区采用LTE的通信制式，LTE网络为全覆盖。在演进过程中，选择部分通信小区所在的接入网设备新建采用NR的通信制式的小区(简称为NR小区)，新建的NR小区与同覆盖的采用LTE的通信制式的小区(简称为LTE小区)通过动态频谱共享(Dynamic Spectrum Sharing，DSS)的功能共享使用部分频率资源。后续演进过程中，逐渐增大NR的通信制式小区部署范围。需要说明的是，图3中的一个六边形区域表示一个小区的覆盖范围，以下图示中相同标注可以参考该说明。需要说明的是，图3中邻近的支持DSS的NR小区和不支持DSS的LTE小区组成的网络架构可以参照图1A和图2A所示的网络架构。参见图4，是本申请实施例提供的又一种网络架构的示意图。在图4所示的区域范围内包含多个通信小区，其中部分通信小区采用LTE通信制式。在演进过程中，选择部分LTE通信制式小区所在的接入网设备中新建NR小区，新建的NR小区与同覆盖的LTE小区通过DSS的功能共享使用部分频率资源。其他通信小区所在的接入网设备直接新建NR制式小区，以使得NR网络为全覆盖。后续演进过程中，逐渐减小LTE的通信制式小区部署范围。需要说明的是，图4中邻近的支持DSS的LTE小区和不支持DSS的NR小区组成的网络架构可以参照图1A和图2A所示的网络架构。
参见图5，是本申请实施例提供的又一种网络架构的示意图。在图5所示的区域范围内包含多个通信小区，这些通信小区中左边区域的通信小区采用LTE的通信制式，右边区域的通信小区采用NR的通信制式。通过LTE退让频谱方式的演进NR，也即是说，逐渐减小LTE的通信制式的频率占用范围，逐渐增大NR的通信制式的频率占用范围。需要说明的是，图5中邻近的LTE小区和NR小区组成的网络架构可以参照图1A和图2A所示的网络架构。
参见图6A-图6B，是本申请实施例提供的又一些种网络架构的示意图。在图6A-图6B所示的区域范围内包含多个通信小区，这些通信小区通过DSS的功能部署了全覆盖的LTE网络和NR网络。但在一些实现场景中，在接入网设备的某些功能开启后，可以基于负载动态地选择关闭LTE网络(可理解为不使用LTE的通信制式进行通信，可参照图6A所示)或者关闭NR网络(可理解为不使用NR的通信制式进行通信，可参照图6B所示)，形成部分区域、部分接入网设备或者部分时间出现LTE不连续插花或者NR不连续插花的场景。需要说明的是，图6A中邻近的支持DSS的LTE小区和不支持DSS的NR小区组成的网络架构可以参照图1A和图2A所示的网络架构。图6B中邻近的支持DSS的NR小区和不支持DSS的LTE小区组成的网络架构可以参照图1A和图2A所示的网络架构。
在LTE和NR同频组网的边界区域，终端设备容易受到远近干扰的影响。以下对远近效应的形成原因作出介绍。参见图7，是本申请实施例提供的又一种网络架构的示意图。示例性的，图7所示的网络架构可以以图1A所示的网络架构为例。在图7所示的网络架构中包括接入网设备(可参照图1A中的接入网设备1)的天线1和接入网设备(可参照图1A中的接入网设备2)的天线2，以及终端设备1(可参照图1A中的终端设备1)。其中，天线1为接入LTE小区的终端设备提供通信信号，天线2为接入NR小区的终端设备提供通信信号。天线1与天线2所属的接入网设备可以是同一个接入网设备，也可以是不同的接入网设备。
在图7所示的网络架构中，LTE小区和NR小区均位于F1这个频段上，终端设备1原本接入在LTE小区中。天线1通过LTE小区向接入LTE小区中终端设备1发送信号(即服务信号)，天线2可以通过NR小区向接入NR小区中的一个或者多个终端设备发送信号。在天线2通过NR小区向一个或者多个终端设备发送信号时，终端设备1可能会接收到天线2发送的信号，该信号为终端设备1接收到的邻区信号，该信号对终端设备1与天线1之间的通信造成干扰，从而该信号可以认为干扰信号。在终端设备1从LTE小区的覆盖范围向NR小区的覆盖范围移动的过程中，终端设备1接收到的LTE小区发送的服务信号越来越弱，NR小区发送的服务信号(可理解为干扰信号)越来越强。
由于LTE和NR通信系统中，都是通过同一通信制式内的同频测量和切换保障移动终端能够始终处于同一通信制式内的最强信号的小区上，终端设备无法进行无额外功耗的跨制式的同频测量。因此终端设备在满足一定条件(例如，服务小区的信号质量高于预设值)前会一直保持驻扎在LTE小区。相对于终端设备而言，自身驻扎的LTE小区是远点，相邻的NR小区是近点，会造成远近效应，即LTE小区提供的服务信号强度弱于NR小区的邻区信号的强度，NR小区的邻区信号会对终端设备接收到的服务信号造成较强干扰。另外， 为了确保LTE小区的天线1能正常接收到终端设备1发送的上行信号，终端设备1会增大自身发射信号的功率，这样会使得终端设备发送的上行信号干扰接入LTE小区中其他终端设备发送的上行信号。
一般提供通信的运营商网络是多频组网，在终端设备接收到的同频信号较差时，会触发异频/异系统测量和切换到其他频点，因此该终端的远近效应问题会维持到异频/异系统测量和切换后才会解除。参见图8，是本申请实施例提供的又一种网络架构的示意图。在图8所示的网络架构中LTE小区1、LTE小区2、LTE小区3和NR小区1，以及终端设备1。其中，LTE小区1和NR小区1均位于频段F1，E小区2和LTE小区3均位于频段F2。终端设备接入LTE小区1。通过LTE小区2、LTE小区3和NR小区1发送的通信信号对于终端设备1而言均为邻区信号，但由于通过LTE小区2、LTE小区3发送的信号通过LTE小区1发送的信号不在同一频段，通过LTE小区2、LTE小区3发送的信号对于终端设备1而言不是干扰信号；通过NR小区1发送的通信信号与通过LTE小区1发送的在同一频段，因此通过NR小区1发送的通信信号对于终端设备1而言是干扰信号。
在终端设备1从LTE小区1的覆盖范围向NR小区1的覆盖范围移动的过程中，终端设备1接收到的LTE小区1发送的服务信号越来越弱，NR小区1发送的邻区信号(可理解为干扰信号)越来越强。在图8中所示的同频边界上，终端设备1接收到的NR小区1的信号质量强于LTE小区1的信号质量，将触发远近效应。在这个情况下，由于服务小区(LTE小区1)的信号质量高于或等于预设值，因此终端设备1将保持驻扎在LTE小区1，在同频边界右方，系统内异频/异系统切换边界左方的这个区域范围内，终端设备1将持续受到远近效应的影响。在图8中系统内异频/异系统切换边界上，终端设备1接收到LTE小区1)的信号质量低于预设值，接入网设备(LTE小区1对应的接入网设备)将触发终端设备1进行系统内异频/异系统切换。示例性的，终端设备1可以切换到LTE小区3中。切换之后，由于LTE小区3和NR小区1位于不同的频段，终端设备1将不再受到远近效应的影响。
与LTE和NR同频组网的情况相似的，临近的同制式异频小区，但频率范围有重叠的情况下，终端设备也容易受到远近干扰的影响。以图1B中的LTE小区6和LTE小区7为例，终端设备6在进行同频测量的过程中，由于LTE小区6和LTE小区7的下行参考信号的中心频点不相同，终端设备6不能检测到LTE小区7的下行参考信号。因此终端设备6在满足一定条件(例如，LTE小区6的信号质量高于预设值)前会一直保持驻扎在LTE小区6。相对于终端设备6而言，自身驻扎的LTE小区6是远点，相邻的LTE小区7是近点，会造成远近效应，即LTE小区6提供的服务信号强度弱于LTE小区7的邻区信号的强度，LTE小区7的邻区信号会对终端设备6接收到的服务信号造成较强干扰。另外，为了确保LTE小区6能正常接收到终端设备6发送的上行信号，终端设备6会增大自身发射信号的功率，这样会使得终端设备6发送的上行信号干扰接入LTE小区6中其他终端设备发送的上行信号。
下面基于上述内容中介绍的网络架构、终端设备以及接入网设备，对本申请实施例提供的一种小区的测量方法进行介绍。为了便于理解，以图1A所示的网络结构为例。在本 申请实施例中，将在NR小区1中新建一个LTE小区4(可参照图9所示的网络架构)。LTE小区4占用了原属于NR小区1的部分时频资源，向终端设备发送下行参考信号。在终端设备1在同一通信制式内进行同频测量的过程中，终端设备可以通过LTE小区4发送的下行参考信号，检测到LTE小区4的存在，以及LTE小区4的信号质量。其中，由于LTE小区4占用的原NR小区1的部分时频资源发送下行参考信号，LTE小区4的信号质量可以视为NR小区1的信号质量。
在LTE小区4的信号质量高于LTE小区1的信号质量的情况下，终端设备向第一接入网设备反馈的同频测量报告中将包含LTE小区4的信息。其中，LTE小区4的信号质量高于LTE小区1的信号质量，表明与LTE小区1同频异制式的NR小区1的邻区信号强于LTE小区1的服务信号，这种情况下会引发远近干扰的问题。
之后，接入网设备1可以根据同频测量报告中的LTE小区4的信息，确定当前移动终端所处环境中的同频异制式的邻区信号强于服务信号。接着，接入网设备1将终端设备1迁移至同制式异频小区或者异制式的小区，可以避免远近干扰的问题。
参见图10，是本申请实施例提供的小区的测量方法的流程图。该方法包括以下步骤。需要说明的是，以下内容中的第一接入网设备可以为图9中的接入网设备1，第一服务小区可以为图9中的LTE小区1，虚拟小区可以为图9中的LTE小区4，第二服务小区可以为图9中的NR小区1，终端设备可以为图9中的终端设备1。其中，服务小区是可以为终端设备提供接入、上下行数据传输等服务的小区，也可以称为正常小区或者小区。虚拟小区是仅是向终端设备发送下行信号，便于终端设备进行小区测量的小区，不为终端设备提供接入，或者上下行数据传输服务的小区。虚拟小区还可以称为虚小区、模拟小区，等等。上述名称仅用于区分这两种类型的小区，在实际应用过程中，还可以存在其他的名称，本实施例不做限制。
S101、第一接入网设备通过第一服务小区向终端设备发送第一测量控制信息。
其中，第一服务小区为终端设备当前接入(或称为驻扎)的通信小区。在一些实施例中，在终端设备成功接入第一服务小区之后，第一接入网设备通过第一服务小区向终端设备发送第一测量控制信息。需要说明的是，在终端设备驻扎在第一服务小区的过程中，会持续根据该第一测量控制信息进行同频测量，该同频测量不会引起终端设备额外的功能消耗。
在一些实施方式中，所述第一测量控制信息中包括指示信息，该指示信息用于指示测量事件的类型。示例性的，测量事件的类型可以包括A1事件(表示服务小区信号质量高于一定门限)，A2事件(表示服务小区信号质量低于一定门限)，A3事件(表示同频邻区信号质量高于服务小区信号质量)，等等。在本申请实施例中，所述第一测量控制信息中包括指示A3事件的指示信息。也即是说，在本申请实施例中，第一测量控制信息用于指示终端设备，在同频邻区信号质量高于服务小区信号质量的情况下，向第一接入网设备反馈第一测量报告。其中，信号质量也可以理解为信号强度，小区的参考信号接收功率(Reference Signal Receiving Power，RSRP)可以是信号质量的参考指标。该信号质量也可以存在其他的参考指标，本申请对此不作限定。
在一些实施方式中，所述第一测量控制信息用于指示所述终端设备测量虚拟小区的下 行参考信号的质量。其中，所述第一服务小区的所述下行参考信号和所述虚拟小区的所述下行参考信号的中心频点相同。通过这种方式，可以指示终端设备根据虚拟小区的所述下行参考信号的中心频点进行同频检测，从而使得终端设备可以检测到虚拟小区。
其中，所述虚拟小区的频率范围包含在第二服务小区的频率范围中，所述第二服务小区与所述第一服务小区的频率范围有重叠；所述第二服务小区的制式与所述第一服务小区的制式不同(示例性的，对应图9所示的情况)。或者，所述第二服务小区的制式与所述第一服务小区的制式相同，且所述第二服务小区的所述下行参考信号与所述第一服务小区的所述下行参考信号的中心频点不同(示例性的，对应图1B所示的情况)。
在第一服务小区所支持的通信制式不同的情况下，所述第一测量控制信息中包含的内容存在差异。以下对可能的两种情况分别进行介绍。
在一种可能的情况中，所述第一服务小区(或虚拟小区)所支持的通信制式为LTE中的通信制式，第二服务小区所支持的通信制式为NR中的通信制式。第一测量控制信息中可以包含小区的下行参考信号的中心频点和测量带宽。其中，小区的下行参考信号的中心频点与第一服务小区、虚拟小区的所述下行参考信号的中心频点相同，测量带宽为虚拟小区的带宽。可选的，所述虚拟小区的带宽为1.4MHz，3MHz，5MHz，10MHz，15MHz，20MHz中的一项。
根据小区的下行参考信号的中心频点和测量带宽可以确定出第一频率范围，该第一频率范围与虚拟小区的频率范围相同。参见图11，是本申请实施例提供的一种第一服务小区、虚拟小区和第二服务小区的频率范围的示意图。第一服务小区和虚拟小区的下行参考信号的中心频点相同。第二服务小区与第一服务小区的频率范围有重叠部分。可选的，第一服务小区和第二服务小区的频率范围可以相同，例如，可以均为2600MHz–2620MHz。第一服务小区的频率范围也可以与第二服务小区的频率范围不相同，例如，第一服务小区的频率范围为2600MHz–2620MHz，第二服务小区的频率范围为2600MHz–2640MHz。
在另一种可能的情况中，所述第一服务小区(或虚拟小区)所支持的通信制式为NR中的通信制式，第二服务小区所支持的通信制式为LTE中的通信制式。第一测量控制信息中可以包含同步信号和物理广播信道块(SSB)中下行参考信号(可具体为解调参考信号(Demodulation Reference Signal，DMRS))的中心频点。其中，该包含的SSB中下行参考信号的中心频点与第一服务小区的SSB中下行参考信号的中心频点、虚拟小区的SSB中下行参考信号的中心频点相同。由于在NR中，同频测量的测量带宽为20个资源块(Resource Block，RB)，第一测量控制信息中可以无需包含测量带宽信息。可选的，所述虚拟小区的SSB为20个RB，虚拟小区的带宽可以有多种取值，本申请实施例不作限制。
根据SSB中下行参考信号的中心频点可以确定出第一频率范围，该第一频率范围与虚拟小区的频率范围相同。参见图12，是本申请实施例提供的另一种第一服务小区、虚拟小区和第二服务小区的频率范围的示意图。第一服务小区的SSB中下行参考信号的中心频点和虚拟小区的SSB中下行参考信号的中心频点相同。第二服务小区与第一服务小区的频率范围有重叠部分。可选的，第一服务小区和第二服务小区的频率范围可以相同，例如，可以均为2600MHz–2620MHz。第一服务小区的频率范围也可以与第二服务小区的频率范围不相同，例如，第二服务小区的频率范围为2600MHz–2620MHz，第一服务小区的频率范 围为2600MHz–2640MHz。
在一些实施例中，第一接入网设备可以根据第二接入网设备发送的虚拟小区的下行参考信号的中心频点(可能还包含测量带宽)，生成第一测量控制信息。
在一些实施例中，第二接入网设备在构建虚拟小区时，可以根据第一服务小区的下行参考信号的中心频点和测量带宽构建该虚拟小区；或者可以根据第一服务小区的SSB中下行参考信号的中心频点构建虚拟小区。
S102、第二接入网设备通过虚拟小区和第二服务小区向终端设备发送信号。
需要说明的是，该虚拟小区可以理解为第二接入网设备构建的一个虚小区或者模拟小区。构建虚拟小区的目的主要是为了使得，终端设备进行同频测量的过程中，能够发现虚拟小区，并测量到虚拟小区的信号质量。对于终端设备而言，该虚拟小区的存在可以近似代表同频异制式的第二服务小区的存在。该虚拟小区的信号质量可以近似代表同频异制式的第二服务小区的信号质量。构建虚拟小区的目的不是为了向终端设备提供接入服务(或称为通信服务)。
具体的，第二接入网设备通过所述虚拟小区发送下行信号，所述下行信号包括所述虚拟小区的所述下行参考信号。该下行信号是为了使得终端设备可以发现虚拟小区，以及检测虚拟小区的信号质量。另外，第二接入网设备通过所述第二服务小区发送通信信号，通信信号是为了向接入该第二服务小区的其他终端设备提供通信服务。
对于接入第一服务小区的终端设备而言，第二接入网设备通过虚拟小区和第二服务小区发送的信号均为邻区信号。但由于第二服务小区为异制式的通信小区(或者为同制式异频小区)，在同频测量过程中，终端设备不能检测到第二接入网设备通过第二服务小区发送的信号。
在一些实施例中，第二接入网设备通过所述虚拟小区发送的信号(例如，下行参考信号)所占用的时频资源与通过所述第二服务小区发送的信号所占用的时频资源不同。通过这种方式，可以避免通过所述第二服务小区发送的通信信号对通过所述虚拟小区发送的下行参考信号造成干扰，从而影响同频测量的测量结果。
可选的，所述第二接入网设备通过所述第二服务小区向接入所述第二服务小区的终端设备发送指示信息，所述指示信息用于指示所述接入所述第二服务小区的终端设备的可用时频资源，所述可用时频资源与所述虚拟小区的所述下行信号所占用的时频资源不同；或者用于指示所述接入所述第二服务小区的终端设备不使用所述虚拟小区发送所述下行信号所占用的时频资源。
其中，所述指示信息的指示方式可以包含动态调度指示和半静态资源指示。动态调度指示是指，第二接入网设备在第二服务小区中通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)发送DCI(Downlink Control Information)信息(即理解为指示信息)，该DCI信息用于指示所述接入所述第二服务小区的终端设备的可用时频资源，所述可用时频资源与所述虚拟小区发送所述下行信号所占用的时频资源不同。半静态资源指示是指，第二接入网设备在第二服务小区中发送RRC重配置消息(即理解为指示信息)，该RRC重配置消息用于指示所述接入所述第二服务小区的终端设备不使用所述虚拟小区发送所述下行信号所占用的时频资源。需要说明的是，第二接入网设备可以采用任意一种 指示方式，也可以针对虚拟小区的不同信道采用不同的指示方式。
在一些实施例中，所述虚拟小区不为终端设备提供接入服务。通过这种方式，第二接入网设备无需为虚拟小区划分较多的时频资源以支持终端设备的通信服务，能为第二服务小区保留尽可能多的时频资源用于支持接入第二服务小区的终端设备的通信服务。
以下对通过虚拟小区发送的下行信号作出进一步的介绍。
在一种可能的实现方式中，虚拟小区所支持的通信制式为LTE中的通信制式。所述下行信号包括所述虚拟小区的下行参考信号。所述下行参考信号包括小区参考信号(Cell-specific Reference Signal，CRS)。该CRS用于终端设备检测虚拟小区的信号质量。
可选的，所述下行信号中还包括主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)、物理广播信道(Physical Broadcast Channel，PBCH)和系统信息块(System Information Block，SIB)1信息中的一项或者多项。其中，PSS、SSS用于终端设备发现(或称为检测到)虚拟小区。物理广播信道用于终端设备检测到系统信息块。可选的，所述系统信息块中携带指示信息(例如，“禁止(Barred)”标识)，所述指示信息用于指示虚拟小区不为终端设备提供接入服务。
其中，系统信息块包含系统信息，一个小区中可以有多个系统信息块，这些系统信息块承载的信息不相同，例如SIB1。SIB1主要承载一些小区的本身的配置信息，例如随机接入相关的信息，PDCCH相关的信息，其他信息块相关的信息，UE接入小区的信息，小区的标识信息等信息。
可选的，第二接入网设备通过所述虚拟小区仅发送PSS、SSS、CRS，以实现虚拟小区不为终端提供接入服务的目的。
在一种可能的实现方式中，虚拟小区所支持的通信制式为NR中的通信制式。所述下行信号中的下行参考信号为解调参考信号(DMRS)，所述下行信号为同步信号和物理广播信道块(SSB)，所述SSB包括所述DMRS。其中，SSB用于终端设备发现(或称为检测到)虚拟小区，以及检测虚拟小区的信号质量。具体的，终端设备的射频在SSB中心频点位置检索SSB中的PSS、SSS以发现小区，并通过SSB中的解调参考信号检测虚拟小区的信号质量。
需要说明的是，步骤S101和步骤S102的执行没有先后顺序的限制。
S103、终端设备根据所述第一测量控制信息测量邻区信号。
在一些实施例中，终端设备可以根据第一测量控制信息确定测量事件，以及需要测量的邻区信号所在的第一频率范围。可选的，终端设备在第一频率范围上测量邻区信号，确定测量到的邻区的小区标识以及信号质量，得到一个或者多个测量结果。
S104、终端设备根据测量结果生成第一测量报告。
其中，所述第一测量报告中包括所述终端设备检测到的一个或者多个小区的信息，所述一个或者多个小区的下行参考信号的质量高于所述第一服务小区的下行参考信号的质量。在一些实施例中，第一测量报告中包含所有下行参考信号的质量高于第一服务小区的小区的信息。
在一些实施例中，第一测量控制信息中包含有指示第一测量报告中邻区数量的最大值(例如为N)的指示信息。那么，第一测量报告中最多包含有N个的小区的信息。包含的 N个小区的信号质量强于剩余的测量出的邻区的信号质量。
在本申请实施例中，所述第一测量报告指示所述虚拟小区的下行参考信号的质量。所述第一测量报告中包含所述虚拟小区的测量结果，表明所述虚拟小区的下行参考信号的质量高于所述第一服务小区的下行参考信号的质量。需要说明的是，由于虚拟小区占用的原第二服务小区的部分时频资源发送下行信号，虚拟小区的信号质量可以视为第二服务小区的信号质量。在这种情况下，通过第二服务小区发送的信号将对终端设备与第一网络设备之间的通信造成影响，容易引发远近干扰的问题。
S105、终端设备向第一接入网设备发送所述第一测量报告。
S106、在第一接入网设备从所述终端设备接收第一测量报告之后，在所述虚拟小区的下行参考信号的质量高于所述第一服务小区的下行参考信号的质量的情况下，所述第一接入网设备将所述终端设备迁移至第三服务小区。
其中，所述第三服务小区与所述第一服务小区制式相同，且所述第三服务小区与所述第一服务小区的所述下行参考信号的中心频点不同，或者所述第三服务小区与所述第一服务小区制式不同。也即是说，第三服务小区与第一服务小区是同制式异频小区，或者是异制式小区。需要说明的是，第三服务小区可以是第二服务小区，也可以是其他服务小区。
可选的，所述虚拟小区的下行参考信号的质量高于所述第一服务小区的下行参考信号的质量，可以理解为上述第一测量报告包括所述虚拟小区的信息，也就是说虚拟小区的下行参考信号的质量高于所述第一服务小区的下行参考信号的质量，终端设备才上报所述虚拟小区的信息，上述第一测量报告可以隐含地指示所述虚拟小区的下行参考信号的质量高于所述第一服务小区的下行参考信号的质量。
在一些实施例中，所述第一接入网设备将所述终端设备迁移至第三服务小区的前提条件还可以存在其他情况。以下对一些可能的前提条件进行介绍。
可选的，在所述虚拟小区的下行参考信号的质量高于所述第一服务小区的下行参考信号的质量，且所述虚拟小区的下行参考信号的质量高于所述第一测量报告包含的其他小区的下行参考信号的质量的情况下，所述第一接入网设备将所述终端设备迁移至第三服务小区。上述这种情况表明，与第一服务小区同频异制式的第二服务小区的邻区信号是检测出的邻区信号中最强的，第二服务小区的邻区信号对第一服务小区的服务信号的干扰较强，这种情况下会极易引发远近干扰的问题。
可选的，在所述虚拟小区的下行参考信号的质量高于所述第一服务小区的下行参考信号的质量，且所述虚拟小区的下行参考信号的质量高于预设值的情况下，所述第一接入网设备将所述终端设备迁移至第三服务小区。可选的，该预设值可以为预先设定的一个与驻扎小区信号质量的相对门限值，也可以为预先设定的一个绝对门限值。上述这种情况表明，虚拟小区的信号质量较强，对第一服务小区的服务信号的干扰较强，这种情况下会极易引发远近干扰的问题。
可选的，所述第一接入网设备将所述终端设备迁移至第三服务小区可能为：第一接入网设备将终端设备切换至第三服务小区。或者，该方式可能为第一接入网设备将终端设备重定向至第三服务小区。
接下来，介绍第一接入网设备将所述终端设备迁移至第三服务小区的一些可能的实现 方式。

在一些实现方式中，所述第一接入网设备存储有与所述第一服务小区相邻的一个或者多个服务小区的小区标识，所述一个或者多个服务小区的小区标识包括所述第三服务小区的小区标识，所述第一接入网设备将所述终端设备迁移至第三服务小区，包括：所述第一接入网设备从存储的与所述第一服务小区相邻的一个或者多个服务小区中选取所述第三服务小区；所述第一接入网设备将所述终端设备迁移至所述第三服务小区。可选的，所述第一服务小区相邻的一个或者多个服务小区的小区标识可以存储在邻区列表中。该小区标识可以为物理小区标识(Physical Cell Identifier，PCI)。
接下来，介绍第一接入网设备确定第一测量报告中包含虚拟小区的信息的一些可能的实现方式。
在一些实现方式中，所述第一接入网设备存储有所述虚拟小区的小区标识，所述第一测量结果包括所述虚拟小区的小区标识。可选的，第一接入网设备可以存储有虚拟小区列表，所述虚拟小区列表包含有预设的多个虚拟小区的小区标识。

需要说明的是，上述实施例以图1A对应的网络架构为例，介绍了本申请实施例提供的一种小区的测量方法的实施步骤。
在另一些实施例中，该方法还可以应用于图1B所对应的网络架构。在图1B所示的网络架构中，在LTE小区7中新建LTE小区8(可参见图13所示的网络架构)。其中，LTE小区8可以视为上述内容中介绍的虚拟小区，LTE小区6可以视为上述内容中介绍的第一服务小区，LTE小区7可以视为上述内容中介绍的第二服务小区，终端设备6可以视为上述内容中介绍的终端设备。LTE小区6与接入网设备4对应，LTE小区7和LTE小区7均与接入网设备5对应。
