Description

一种测量能力上报的方法、系统及装置
本申请要求在2019年9月30日提交中国国家知识产权局、申请号为201910945417.8的中国专利申请的优先权，发明名称为“一种测量能力上报的方法、系统及装置”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
本申请实施例涉及通信技术领域，尤其涉及一种测量能力上报方法及装置。
背景技术
在移动通信中，为了节省成本，一个终端设备(User Equipment，UE)通常只有单个接收通路，同一时刻只能在一个频点上接收信号，即同一时刻只能接收一个小区的信号。在蜂窝移动通信系统中，小区重选和切换是非常重要的功能。为了顺利实现小区重选，UE需要对不同小区的信号质量进行测量，以便选择合适的小区进行驻留，满足移动性需求。当UE在接收其服务小区发送的数据的过程中，如果需要对其他小区进行异频测量或异系统测量等测量操作，接收机需要离开当前的频点到需要测量的频点测量一段时间段。为了保证UE和当前服务小区(小区1)的无线链路质量，UE通常在指定的时间段，停止接收其服务小区的信号以及数据，并接收其他小区(如小区2)的信号进行异频测量或异系统测量。当该时间段结束后，UE再开始接收其服务小区的信号以及数据。这个时间段称为测量间隙(Measurement GAP)。图1为长期演进系统(Long Term Evolution，LTE)下规定的一种GAP类型：测量周期为40ms，测量间隙长度为6ms。UE在测量间隙内，先探测小区2的同步信号，以小区2的同步信号和小区2取得同步，再对小区2发送的参考信号进行相关测量，从而完成对小区2的信号质量测量。
为了向移动用户提供更高的数据速率，长期演进系统(Long Term Evolution，LTE)提出了载波聚合技术(Carrier Aggregation，CA)，其目的是为具有相应能力的终端提供更大带宽，提高终端的峰值速度。目前LTE系统下，终端可以支持很多不同频段的载波聚合，具有多个接收通路，具备在不需要配置测量间隙的情况下直接进行异频测量或异系统测量的能力。这样就可以不打断原服务区的数据传输，对终端原服务区的服务不造成影响。但LTE支持的频段、CA(载波聚合)组合很多，需要测量的异频/异系统频段也很多。基于成本考虑，终端通常只能支持有限个数的载波聚合不需要测量间隙进行异频测量或异系统测量，不能支持所有载波聚合下都不需要测量间隙进行异频测量或异系统测量。目前协议规定，LTE可以通过测量能力信息上报哪些测量频段组合需要测量间隙，哪些测量频段组合不需要测量间隙。为使基站知道终端的测量能力，终端需要对所有频段和CA组合下执行异频或异系统测量是否需要测量间隙进行上报。因此会存在上报测量能力的消息比特数多、信息量大、上报困难的问题。5G NR(New Radio)系统相对于4G LTE系统增加了更多的频段、CA、4G5G双连接(E-UTRA-NR Dual Connectivity，EN-DC)、5G4G双连接(NR-E-UTRA Dual Connectivity，NE-DC)等频段组合方式，如果继续沿用LTE系统下终端上报测量能力的方式，测量能力的消息信息量会更加庞大，上报会更加困难。
发明内容
本申请实施例提供一种测量能力上报方法及装置，用于解决终端上报是否需要测量间隙 的测量能力时，上报消息比特数太大，上报困难的问题。
一方面，本申请实施例提供一种网络系统，包括：终端和网络设备，终端驻留在第一小区；网络设备被配置为，向终端发送第一能力查询消息；接收终端发送的第一能力信息；该第一能力信息包括：终端支持的第一小区相关的频段和频段组合，终端支持的第二小区相关的频段和频段组合，第一小区相关的测量能力，以及指示信息；其中，测量能力用于指示终端在异频或异系统测量时是否需要测量间隙；指示信息用于通知网络设备，该第一能力信息上报的测量能力只包含与第一小区相关的频段和频段组合的测量能力；根据第一能力信息确定终端进行异频或异系统测量时是否需要分配测量间隙；终端被配置为：接收网络设备发送的第一能力查询消息；向网络设备发送第一能力信息。
在该方案中，以终端所驻留的小区为第一小区，频段为Band1，邻小区为第二小区，频段为Band3为例。终端在接收到网络设备发送的第一能力查询消息后，可上报第一能力信息，该第一能力信息包括：(a)终端支持的所有的频段和频段能力，即第一小区相关的频段和频段组合和第二小区相关的频段和频段组合。示例性的，终端所支持的频段能力包含但不限于小区1和小区2，如果终端支持更多的小区频段，则可上报终端支持的所有频段和频段组合。示例性，参见表三，终端支持的频段能力可以有：Band1、Band3、Band5、Band38，终端所在主小区(小区1)频段为Band1；终端支持的异系统频段(NR支持的band能力)有：N77、N78；终端支持的频段组合有：Band1a+Band1a、Band3a+Band5a、Band1a+Band38a、Band1a+Band3a+Band5a、Band3a +Band38a(a表示band的宽度)；(b)测量能力，只上报和当前主小区(第一小区)相关的测量能力；(c)指示信息，用于通知所述网络设备，第一能力信息上报的测量能力只包含与主小区相关的频段和频段组合的测量能力。本方案中，终端在上报测量能力消息时，仅上报和主服务区(Pcell)相关的频段和频段组合能力是否需要配置测量间隙，省掉了大量其他与Pcell不相关的频段组合的测量能力的上报。因此可以大大节省测量能力上报的消息量，提升测量能力上报的成功率。
在一种可能的设计中，网络设备根据第一能力信息，将终端上报的测量能力与终端支持的频段和频段组合顺序对应，确定并记录终端在第一小区相关的频段和频段组合进行异频或异系统测量时是否需要分配测量间隙。根据终端上报的能力信息中的指示信息，网络设备可知道终端上报的测量能力只上报了和主小区相关的频段和频段组合的测量能力。因此网络设备需要将终端上报的终端支持的所有的频段和频段组合中与主小区相关的频段和频段组合，与终端上报的仅和当前主小区相关的测量能力顺序对应，从而确定主小区所在频段和频段组合的测量能力。然后网络设备会记录终端已经上报过的测量能力信息，在终端重新接入/切换到与主小区频段相同的小区后，不用再查询该终端的测量能力。
此后，网络设备可根据终端上报的第一能力信息确定终端进行异频或异系统测量时是否需要分配测量间隙。一般来讲，终端在主小区PCell发起无线资源控制层(Radio Resource Control，RRC)连接流程，网络设备根据终端上报的测量能力来确定是否要配置测量Gap。
在一种可能的设计中，网络设备还被配置为：向终端发送第一消息，第一消息用于测量第二小区的网络参数，该第一消息包括所述测量间隙信息。如果终端需要Gap进行异频或异系统测量，网络设备下发第一消息：测量控制信息，包括频点信息、测量带宽、测量参数、测量报告参数等，并配置测量Gap周期。
在一种可能的设计中，网络设备还被配置为：向终端发送第二消息，第二消息用于测量第二小区的网络参数，该第二消息不包括测量间隙信息。如果终端不需要启动Gap进行异频或异系统测量，则网络设备发送第二消息：测量控制信息，且不配置测量间隙。
在一种可能的设计中，终端还被配置为：根据第一消息或第二消息，向网络设备发送测量报告。
在一种可能的设计中，网络设备还被配置为：根据测量报告，指示终端进行小区切换，从第一小区切换到第二小区；向终端发送第二能力查询消息；接收终端发送的第二能力信息；该第二能力信息包括：终端支持的第一小区相关的频段，终端支持的第二小区相关的频段和频段组合，第二小区相关的测量能力，以及指示信息；其中，测量能力用于指示所述终端在异频或异系统测量时是否需要测量间隙；指示信息用于通知所述网络设备，第二能力信息只上报和第二小区相关的频段和频段组合的测量能力；根据第二能力信息确定终端进行异频或异系统测量时是否需要分配测量间隙。终端还被配置为：接收网络设备发送的第二能力查询消息；向网络设备发送第二能力信息。
在该方案中，网络设备根据终端上报的测量结果进行分析，若终端设备驻留的Pcel l的网络质量和第二小区的信号质量满足预设条件时，网络设备指示终端进行小区切换，从第一小区切换到第二小区，即第二小区成为主小区。其中小区切换包括同系统内的小区切换或异系统间的小区切换。并且网络设备通过查看，发现终端之前未驻入过第二小区，因此下发第二能力查询消息，该第二能力查询消息中包括查询终端是否需要测量间隙。终端响应于第二能力查询消息，上报第二能力信息，该第二能力信息包括：终端支持的所有的频段；仅和当前主小区(小区2)相关的频段组合；上报仅和当前主小区相关的测量能力；以及指示信息：用于通知所述网络设备，第二能力信息上报的测量能力只包含与主小区相关的频段和频段组合的测量能力。在该方案中，终端上报的第二能力信息中，不用再上报除主小区(第二小区)以外的其他频段组合，进一步节省上报消息的字节数。
在一种可能的设计中，在网络设备向终端发送第二能力查询消息后，网络设备还被配置为：接收终端发送第三能力信息；该第三能力信息包括：第二小区相关的测量能力和指示信息；所述测量能力用于指示所述终端在异频或异系统测量时是否需要测量间隙；所述指示信息用于通知所述网络设备，第三能力信息只上报和第二小区相关的频段和频段组合的测量能力；根据第三能力信息确定终端进行异频或异系统测量时是否需要分配测量间隙。终端还被配置为：向网络设备发送第三能力信息。
在该方案中，终端上报的第三能力信息中，只上报主小区相关的测量能力，不用再上报终端支持的小区的频段和频段组合，可进一步节省上报消息的字节数。
在一种可能的设计中，网络设备根据第三能力信息确定终端进行异频或异系统测量时是否需要分配测量间隙，具体包括：网络设备根据第三能力信息，将终端上报的测量能力和终端之前上报的频段能力顺序对应，确定并记录终端在第二小区相关的频段和频段组合进行异频或异系统测量时是否需要分配测量间隙。在该方案中，根据终端上报的能力信息中的指示信息，网络设备可知道终端上报的测量能力只上报了和主小区相关的频段和频段组合的测量能力。因此网络设备需要将终端之前上报的能力信息中与当前主小区相关的频段、频段组合按顺序与终端上报的仅和当前主小区相关的测量能力相对应，从而确定当前主小区所在频段和频段组合的测量能力。并且，网络设备会对终端已经上报过的测量能力信息进行记录，在重新接入/切换到主小区频段相同的小区后，不用再查询该终端的测量能力。
在一种可能的设计中，所述网络设备还被配置为：指示终端进行小区切换，从第二小区切换到第一小区；不发送第三能力查询消息给所述终端。
在该方案中，当网络设备指示终端从第二小区切回到第一小区后，网络设备可知道终端之前已经上报过第一小区相关频段和频段组合的能力信息，因此不需要再次查询终端的测量 能力。
在一种可能的设计中，频段组合包括以下至少一项：载波聚合(Carrier Aggregation，CA)、4G5G双连接(E-UTRA-NR Dual Connectivity，EN-DC)、5G4G双连接(NR-E-UTRA Dual Connectivity，NE-DC)、独立组网(standalone，SA)、非独立组网(non-standalone，NSA)频段组合方式。
在一种可能的设计中，指示信息为MeasurementCapabiltyOnlyPcellRelated，其中MeasurementCapabiltyOnlyPcellRelated：True表示所述终端上报的测量能力只包含与主小区相关的频段和频段组合的测量能力。当终端驻留在第一小区时，主小区为第一小区，则终端上报的测量能力只包含与第一小区相关的频段和频段组合的测量能力。当终端从第一小区切换到第二小区时，主小区为第二小区，则终端上报的测量能力只包含与第二小区相关的频段和频段组合的测量能力。
在一种可能的设计中，能力信息至少包括InterFreqNeedForGaps以及interRAT-NeedForGaps中的任一项。

具体实施方式
目前，根据3GPP协议的规定，LTE可以通过interFreqNeedForGaps/interRAT-NeedForGaps信元在能力信息中标识当前终端设备的测量能力。协议中的描述分别为“Indicates need for measurement Gaps when operating on the E UTRA band given by the entry in bandListEUTRA or on the E-UTRA band combination given by the entry in bandCombinationListEUTRA and measuring on the E UTRA band given by the entry in interFreqBandList.”以及“Indicates need for DL measurement Gaps when operating on the E UTRA band given by the entry in bandListEUTRA or on the E-UTRA band combination given by the entry in bandCombinationListEUTRA and measuring on the inter-RAT band given by the entry in the interRAT-BandList”。具体为：InterFreqNeedForGaps用于标识某一CA组合或者服务小区为单band测量异频点是否需要Gap，interRAT-NeedForGaps用于标识某一CA组合或者服务小区为单band测量异系统是否需要Gap。
可通过1比特(bit)False(F)或True(T)指示服务区频段/CA组合测量异频频段或异系统频段是否需要测量间隙，其中，True为需要，False为不需要。通过该方法，终端通过能力信息对终端所支持的所有频段/CA组合需要测量的所有异频频段或异系统频段中是否需要测量间隙进行上报，网络设备根据终端上报的能力信息决定测量时是否配置测量间隙。
为了便于描述，可以将表一理解为当前终端设备的测量能力，值得说明的是，表一只是提供一种终端设备测量能力的一种表现形式。如表一所示，示出了终端设备的异频测量能力(例如通过信元InterFreqNeedforGaps标识)和异系统测量能力(例如通过信元interRAT-NeedForGaps标识)，以下简称“测量能力”或者“是否需要测量Gap”或者“是否需要分配Gap能力”或者“Gap能力”、“Gap测量能力”等。
示例性的，如表一所示，终端支持的LTE band能力有Band1、Band3、Band5、Band38；
终端支持的CA能力有Band1a+Band1a、Band3a+Band5a、Band1a+Band38a、Band1a+Band3a+Band5a和Band3a+Band38a；其中，a表示频段的宽度。示例性的，Band1可以是从1920MHz-1980MHz的频段，Band1a+Band1a可以是1920MHz-1930MHz+1960MHz-1980MHz的载波聚合。
示例性的，终端支持的异系统(2G系统)band能力有gsm850和gsm1800。同时，表一示出终端上报的能力消息中包含测量能力，即终端在支持的频段和频段组合的场景下，执行异频或异系统测量是否需要测量间隙的能力。T表示需要测量间隙，F表示不需要测量间隙。示例性的，如表一中的第二列第三行所示，当终端驻留在服务区Band1测量异频Band3的信号质量时，不需要测量间隙。再如表一中的第八列第七行所示，当终端在服务区Band1a+Band38a测量异系统gsm1800的信号质量时，需要测量间隙。示例性的，Band1可以是从1920MHz-1980MHz的频段，Band1测量Band1的信号质量，可以是指Band1的1920MHz-1930MHz频段测量Band1的1960MHz-1980MHz频段的信号质量。
此后，网络设备可根据终端上报的测量能力查询终端进行异频或异系统测量时是否需要配置测量间隙。

假设N是终端支持的频段数，M是终端支持的异系统频段数，L为终端支持的CA组合数，则终端在上报能力信息时，需要上报的信息比特数为(N+L)*(N+M)。以表一为例，则N＝4，M＝2，L＝5。目前终端典型可支持500个CA组合，20个异频Band测量，10个异系统测量，则需要上报的消息量为(20+500)*(20+10)＝15,600bit。因此上报的消息量很大，上报过程会很困难，且容易出错。
目前上报消息中不支持5G NR的测量能力上报。5G NR支持更多的频段，支持4G5G双连接EN-DC、5G4G双连接NE-DC、NR CA等更多的频段组合。需要测量NR异频、LTE异系统，非独立组网NSA下还需要测量2G3G异系统，需要测量的异频、异系统更多。因此UE更难支持所有频段组合下不配置测量间隙进行异频/异系统的信号质量测量。如表二所示，为部分5G NR系统支持的频段。5G NR的支持的频段组合和所需要测量的频段组合相对LTE更多，如果继续沿用LTE的测量能力消息的上报方法，消息量会更加庞大，上报更加困难。

本申请实施例为解决通信系统中，测量能力中是否需要测量间隙的上报消息比特数太多、消息量大、上报困难的问题，提出一种测量能力上报方法及装置。UE根据所驻留的主小区，不是上报所有频段和频段组合的测量能力，只上报和当前主小区相关的频段和频段组合的测量能力。

网络设备1可以为支持LTE功能的4G基站，即eNB，根据eNB的无线电覆盖范围，通常可以包括至少一个服务小区(cell)，即服务小区1，小区是为用户提供无线通信业务的一片区域，是无线网络的基本组成单位，eNB也分为可以为多个小区，每个小区可以用不同的无线载波，每个无线载波使用某一载波频点。本申请为便于描述，每一个小区对应一个网络设备，但并不限定，一个网络设备也可以对应多个不同的小区，包括一个主小区和多个辅小区。
在无线技术中，引入了CA(Carrier Aggregation，载波聚合)的概念，简单地说，它可以将多个载波聚合成一个更宽的频谱，同时也可以把一些不连续的频谱碎片聚合到一起，可以理解为载波聚合(Carrier Aggregation,CA)是将2个或更多的载波单元(Component Carrier,CC)聚合在一起以支持更大的传输带宽，为了高效地利用零碎的频谱，CA支持多种方式的聚合：相同或不同带宽的CC；同一频带内，邻接或非邻接的CCs；不同频带内的CCs。
每一个载波单元CC对应一个独立的小区cell，在CA的场景中可以分为以下几种类型的cell：
主小区(Primary Cell,Pcell)：主小区是工作在主频带上的小区，即终端当前驻留的小区。终端设备在该小区进行初始连接建立过程，或开始连接重建立过程。在切换过程中该小区被 指示为主小区；
辅小区(Secondary Cell，Scell)：辅小区是工作在辅频带上的小区。一旦RRC(Radio Resource Control,RRC)连接建立，辅小区就可能被配置以提供额外的无线资源；
Serving Cell：处于RRC_CONNECTED连接态的终端设备，如果没有配置CA，则只有一个Serving Cell，即PCell；如果配置了CA，则Serving Cell集合是由PCell和SCell组成；
Pcell和辅小区Scell是针对CA用户的用户级概念，用户初始接入的载波就是该CA用户的Pcell，主小区是工作在主频带上的小区。终端设备在该小区进行初始连接建立过程，或开始连接重建立过程。在切换过程中该小区被指示为主小区；辅小区是工作在辅频带上的小区。一旦RRC(Radio Resource Control,RRC)连接建立，辅小区就可能被配置以提供额外的无线资源(见36.331的3.1节)。
示例性的，如表一所示，终端支持的CA组合可以是Band1a+Band38a，其中Band1可以是主小区所在频段，Band38可以是辅小区所在频段。
在具体实现时，图2所示终端、网络设备可采用图3所示的组成结构或者包括图3所示的部件。

其中，存储器304可以是只读存储器(read-only memory，ROM)或可存储静态信息和/或指令的其他类型的静态存储设备，也可以是随机存取存储器(random access memory，RAM)或者可存储信息和/或指令的其他类型的动态存储设备，还可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。
一种可能的设计中，存储器304可以独立于处理器301存在，即存储器304可以为处理器301外部的存储器，此时，存储器304可以通过通信线路302与处理器301相连接，用于存储指令或者程序代码。处理器301调用并执行存储器304中存储的指令或程序代码时，能够实现本申请下述实施例提供的通信方法。又一种可能的设计中，存储器304也可以和处理器301集成在一起，即存储器304可以为处理器301的内部存储器，例如，该存储器304为高速缓存，可以用于暂存一些数据和/或指令信息等。

下面结合图2所示的通信系统，对本申请实施例提供的测量能力上报方法进行描述。
图4为本申请实施例提供的一种终端进行注册初始接入网络时的流程图。本实施例中，终端在上报能力信息时，可以只上报和主小区相关的频段和频段组合的测量能力。如图4所示，以网络设备为LTE系统，主小区为小区1，频段为Band1，邻小区为小区2，频段为Band3为例，该方法可以包括：步骤401：网络设备向终端下发第一能力查询消息，该第一能力查询消息中包括查询终端是否需要测量间隙；
示例性的，网络设备可通过UECapabilityEnqury下发第一能力查询消息。
本申请实施例以终端初始注册接入小区1网络为例，一般来讲，终端设备想要获取服务，需要向网络注册，这个注册过程被称为Attach(以LTE系统为例)，终端设备在Attach过程中可以上报终端设备的测量能力。根据协议规定，例如标识当前终端设备测量能力的参数可以为interFreqNeedForGaps以及interRAT-NeedForGaps。
步骤402：终端上报第一能力信息，该第一能力信息包括：
(a)终端支持的所有的频段能力和频段组合能力；
示例性的，参见表三，终端支持的频段能力有：Band1、Band3、Band5、Band38，终端所在主小区(小区1)频段为Band1；终端支持的异系统频段(NR支持的band能力)有：N77、N78；终端支持的频段组合有：Band1a+Band1a、Band3a+Band5a、Band1a+Band38a、Band1a+Band3a+Band5a、Band3a +Band38a(a表示band的宽度)。
需要说明的是，在4G LTE系统下，频段组合可以是指CA组合，在5G NR系统下，频段组合可以是EN-DC、NE-DC、SA、NSA等频段组合方式。
(b)测量能力：上报仅和当前主小区相关的测量能力；
只上报与主小区相关的频段和频段组合的测量能力，即终端在当前主小区频段或者在与主小区相关的频段组合的场景下，执行异频或异系统测量是否需要测量间隙的能力。
示例性的，以终端所在主小区频段为Band1为例，表三中与主小区相关的频段和频段组合为：Band1、Band1a+Band1a、Band1a+Band38a、Band1a+Band3a+Band5a。则终端仅上报 和主小区相关的频段和频段组合能力是否需要配置测量间隙，如：Band1测量Band1不需要测量间隙，Band1a+Band1a测量Band1需要测量间隙，Band1a+Band1a测量Band3不需要测量间隙等。参见表四中的第二列、第六列、第八列和第九列所示，一共需要上报24个比特(现有技术中需要上报所有频段和频段组合的测量能力，一共9*6＝54比特)。省掉不包含主小区的其他频段和频段组合是否需要测量间隙的上报，如Band3测量Band1，Band3测量Band3，Band5测量Band1，Band5测量Band3等，Band3a+Band5a测量Band1，Band3a+Band5a测量Band3等，如表四中的灰色部分所示。其中T表示需要测量间隙，F表示不需要测量间隙。
(c)指示消息：用于通知网络设备，该第一能力信息只上报了和主小区相关的频段和频段组合的测量能力，未上报所有频段组合的测量能力，切换小区后需要再查询终端的测量能力。
示例性的，指示消息可以是MeasurementCapabiltyOnlyPcellRelated，可通过1比特False(F)或True(T)进行指示。
MeasurementCapabiltyOnlyPcellRelated：True(1)：当该bit信息为True时，指示目前终端上报的是否需要测量间隙的测量能力消息仅为主小区频段相关的信息。网络设备需要将终端上报的测量能力与主小区相关的频段和频段组合顺序对应，切换到新的小区后需要判断该新小区相关的频段和频段组合的测量能力是否上报过。如果上报过不需要重新查询，否则需要重新查询。
MeasurementCapabiltyOnlyPcellRelated：False(0)：该bit信息为False或没有上报时，说明目前终端上报的是否需要测量间隙的测量能力信息按照目前已有方式上报，网络设备处理方式不变。
本实施例中，指示消息MeasurementCapabiltyOnlyPcellRelated：True。
步骤403：网络设备记录终端的测量能力信息。
网络设备根据终端上报的第一能力信息进行查询，将终端支持的频段和频段能力与上报的主小区相关的测量能力顺序对应，从而确定主小区相关的频段和频段组合的测量能力，并进行记录。
根据终端上报的能力信息中的指示信息MeasurementCapabiltyOnlyPcellRelated：True，网络设备可知道终端上报的测量能力只上报了和主小区相关的频段和频段组合的测量能力。因此网络设备需要将步骤502(a)中终端上报的终端支持的所有的频段能力和频段组合能力中与主小区相关的频段能力和频段组合能力，与步骤502(b)中终端上报的仅和当前主小区相关的测量能力顺序对应，从而确定主小区所在频段和频段组合的测量能力。然后网络设备会记录终端已经上报过的测量能力信息，在终端重新接入/切换到与主小区频段相同的小区后，不用再查询该终端的测量能力。

表四
Figure PCTCN2020116416-appb-000006
当前系统满足触发条件，可启动异频或异系统测量，示例性的，触发进行小区测量的条件，可以是协议中规定的A2事件，即当前的服务小区(小区1)的信号质量低于预定门限值，即Ms+Hys<Thresh，其中，Ms为服务小区测量结果；Hys为异频(Band3)幅度迟滞；Thresh为基于某事件的A2异频门限，A2用于启动异频或者异系统的测量；在一种可能的实施例中，网络设备需要主动发起测量邻小区的需求，还可以是终端的移动性测量等触发条件。此后，网络设备可根据触发条件以及根据终端设备上报的测量能力，确定是否分配相应的Gap。
步骤404：网络设备根据终端上报的测量能力决定是否需要分配Gap。
一般来讲，终端在主小区PCell发起无线资源控制层(Radio Resource Control，RRC)连接流程，网络设备根据终端上报的测量能力来确定是否要配置测量Gap。如果终端需要Gap进行异频测量，网络设备下发测量控制信息(频点信息、测量带宽、测量参数、测量报告参数等)并配置测量Gap周期；如果终端不需要启动Gap进行测量，则网络设备跳过测量Gap的配置，直接下发测量控制信息。
步骤405：当网络设备根据终端上报的测量能力，确定需要分配Gap给终端,则网络设备通过无线资源控制层重配消息(RRC Connection Reconfiguration)下发测量控制信息(频点信息、测量带宽、测量参数、测量报告参数等)并配置测量Gap周期，即网络设备发送第一消息给终端。
通常来讲，网络设备会根据需要发送测量控制信息，以及配置Gap周期至终端设备，用于测量异频或者异系统小区的信息。
在一实施例中，当网络设备根据终端设备上报的测量能力，确定不需要分配Gap给终端,则网络设备在无线资源控制层重配消息(RRC Connection Reconfiguration)配置频点、测量门限、测量带宽、测量参数、测量报告参数等测量控制消息，不分配Gap相关信息，即网络设备发送第二消息给终端。
步骤406：终端根据网络设备发送的测量控制信息进行测量，并上报测量报告。
示例性的，终端可通过MeasurementReport消息上报测量报告。
网路设备根据终端上报的测量结果进行分析，若邻小区(小区2)信号质量比当前主小区信号质量好，并结合其他网络切换策略判断需要进行小区切换，则执行步骤407，进行小区切换。否则不进行小区切换。
测量报告(MR,Measurement Report)是LTE系统的一项重要功能。物理层上报的测量结果可以用于系统中无线资源控制子层完成诸如小区选择/重选及切换等事件的触发，也可以用于网络邻区维护，SCG添加等功能，LTE MR报告还可以包括参考信号接收功率、参考信号接收质量、eNB接收干扰功率、eNB天线到达角、终端设备发射功率余量、上行丢包率、下行丢包率、上行信噪比、PRB粒度eNB接收干扰功率等。基于MR可以进行全网覆盖情况、干扰情况、上行高发射功率、终端设备位置定位分析，例如可利用MR中eNB接收干扰功率RIP统计分析全网干扰情况，定位高干扰小区。在连接态下，网络测量通常有如下几个目的：
1、Pcell的切换，当终端设备驻留的Pcell的网络质量满足预设条件时，例如当前小区的信号质量低于阈值，即触发A2事件(Event A2),网络分配异频点用于测量邻小区的网络质量。同频邻区测量网络不需要指示，终端设备可以在连接态下随时测量。
2、Scell的添加，如果测量的小区满足A4事件，即EvenA4，A4事件的触发条件可以理解为当测量小区大于网络配的某个门限时，网络则可以为用户配置Scell，用户可以通过Pcell和Scell小区与核心网进行数据交换。例如，如图2所示，当终端设备驻留在服务小区1时，此时服务小区1为Pcell,在采用了CA技术之后，终端设备还需要去测量邻小区(例如服务小区2或者服务小区3)的网络参数，当测量的邻小区的网络参数满足网络侧配置的某个门限值，即满足了A4事件的触发条件的时候，网络侧可以根据为终端设备配置Scell小区，从而实现高带宽的数据传输。
3、通过测量报告来进行网络系统操作维护，异频邻区自动配置等操作。
4、在一些特殊的场景下，例如LTE双连接Eutran–dual connetion(EE-DC)以及EN-DC双链接的时候，终端设备也需要测量双链接时的目标小区，例如测量NR(5G小区或者LTE小区。
步骤407：网络设备根据终端上报的测量结果，指示终端进行小区切换。
示例性的，邻小区为小区2，网络设备根据终端上报的测量结果，指示终端进行小区切换。此后小区2成为主小区。并且网络设备需要对终端是否已经上报过与小区2相关的测量能力进行查询，若上报过，则在切换到小区2后不用再查询该终端的测量能力。否则执行步骤408。
示例性的，用于启动同频/异频切换请求的，可以是协议中规定的A3事件，即同频/异频邻区质量比服务小区质量高出一定门限，即Mn+Ofn+Ocn-Hys>Ms+Ofs+Ocs+Off，其中，Mn：邻区(小区2)测量结果；Ms：服务小区(小区1)测量结果；Ofn：频率偏置，邻区频率的特定频率偏置，由参数QoffsetFreq决定，该参数设置得越大，UE重选到特定频点小区的难度变难；该参数设置得越小，UE重选到特定异频频点小区的难度变易。通常设置为0db或1db；Ofs：频率偏置，服务小区频率的特定频率偏置，由参数QoffsetFreq决定。服务小区与邻区为同频时，一般可忽略Ofn、Ofs；Ocn：小区偏移量，邻区的特定小区偏置，由参数CelllndividualOffset(CIO)决定。用于控制同频/异频测量事件发生的难易程度，该值越大越容易触发同频测量报告上报。在邻区中设置，正值容易切换到此邻区，负值变难，特定小区级参数，通常设为0，单位db(分贝)；Ocs：服务小区偏置，服务小区的特定小区偏置，由 参数CellSpecificOffset决定。用于控制服务小区与邻区触发切换的难易程度，该值越小越容易触发测量报告上报。该值通常设置为0，单位db(分贝)；Hys：同频切换幅度迟滞，是事件A3迟滞参数，由参数IntraFreqHoA3Offset决定。该参数表示同频切换测量事件A3的迟滞，可减少由于无线信号波动导致的同频切换事件的触发次数，降低乒乓切换以及误判,该值越大越容易防止乒乓和误判。异频A3幅度迟滞与该参数取值相同。通常设置为4，即2db(单位0.5分贝)；Off：同频切换偏置，是事件A3偏置参数，由参数IntraFreqHoA3Offset决定。当取正值时，此时增加事件触发的难度，延缓切换；当取负值时，此时降低事件触发的难度，提前进行切换。通常设置为2，即1db(单位0.5分贝)。如果忽略频率偏置、小区偏移量、服务小区偏置，即Mn＞MS+Off+Hys(邻区测量值＞服务小区测量值+同频切换幅度迟滞和偏置)，通常可认为邻区大于服务小区3db，即发生切换。异频切换触发事件类型设置为A3时，由InterFreqHoA3Offset(异频A3偏置)决定，通常设置为2或4，即1db或2db(单位0.5分贝)。
步骤408：网络设备下发终端第二能力查询消息，该第二能力查询消息中包括查询终端是否需要测量间隙的能力。
示例性的，网络设备可通过UeMeasureCapabilityEnqury下发测量能力查询消息。
步骤409：终端上报第二能力消息，该第二能力消息包括：
(a)终端支持的所有的频段能力；
示例性的，参见表三，终端支持的频段能力有：Band1、Band3、Band5、Band38，终端所在主小区(小区2)频段为Band3；终端支持的异系统频段(NR支持的band能力)有：N77、N78。
(b)终端上报仅和当前主小区(小区2)相关的频段组合能力；
示例性的，终端上报仅和当前主小区(小区2)相关的频段组合能力：Band3a+Band5a、Band3a +Band38a。
需要说明的是，在4G LTE系统下，频段组合可以是指CA组合，在5G NR系统下，频段组合可以是EN-DC、NE-DC、SA、NSA等频段组合方式。
(c)测量能力：上报仅和当前主小区相关的测量能力；
只上报与当前主小区(小区2)相关的频段和频段组合的测量能力，即终端在当前主小区频段或者在与当前主小区相关的频段组合的场景下，执行异频或异系统测量是否需要测量间隙的能力。
示例性的，终端所在主小区频段为Band3，则终端仅上报和主小区相关的频段和频段组合能力是否需要配置测量间隙，如：Band3测量Band1不需要测量间隙，Band3a+Band5a测量Band38需要测量间隙，Band3a+Band38a测量N77不需要测量间隙等，参见表五中的第三列、第七列、第十列所示。省掉不包含主小区的其他频段和频段组合是否需要测量间隙的上报，如表五中的灰色部分所示。其中T表示需要测量间隙，F表示不需要测量间隙。
(d)指示信息：用于通知网络设备，该能力消息只上报了和主小区相关的频段和频段组合的测量能力，未上报所有频段组合的测量能力，切换小区后需要再查询终端的测量能力。
示例性的，指示消息可以是MeasurementCapabiltyOnlyPcellRelated，可通过1比特False(F)或True(T)进行指示。本实施例中，指示消息MeasurementCapabiltyOnlyPcellRelated：True。
步骤410：网络设备记录终端的测量能力信息。
网络设备根据终端上报的第二能力信息进行查询，将终端上报的频段和频段能力与上报 的主小区相关的测量能力顺序对应，确定当前主小区(小区2)所在频段和频段组合的测量能力，并记录终端已经上报过的测量能力信息。
根据终端上报的能力信息中的指示信息MeasurementCapabiltyOnlyPcellRelated：True，网络设备可知道终端上报的测量能力只上报了和当前主小区(小区2)相关的频段和频段组合的测量能力。因此网络设备需要将终端上报的能力信息中与当前主小区相关的频段能力、频段组合能力和步骤409(c)中终端上报的仅和当前主小区相关的测量能力顺序对应，从而确定当前主小区所在频段和频段组合的测量能力。网络设备记录终端已经上报过的测量能力信息，在重新接入/切换到主小区频段相同的小区后不用再查询该终端的测量能力。
表五
Figure PCTCN2020116416-appb-000007
本申请实施例中，终端进行注册初始接入网络时，当终端接收到网络设备下发的终端能力查询消息后，在上报测量能力消息时，终端仅上报和主服务区(Pcell)相关的频段和频段组合能力是否需要配置测量间隙，省掉了大量其他与Pcell不相关的频段组合的测量能力的上报。因此可以大大节省测量能力上报的消息量，提升测量能力上报的成功率。与现有技术一次上报终端支持的所有频段和频段组合的测量能力信息，本申请实施例上报测量能力消息中省掉了其他与Pcell不相关的频段组合的测量能力。因为在当前小区，服务区频段加测量频段的组合一定是包含Pcell的频段组合，不会出现与Pcell不相关的频段组合，因此省掉后并不影响终端的测量。
在一实施例中，如图5所示，在执行完步骤408后，终端可执行步骤509。在该实施例中，终端上报的能力信息中还可以省略上报终端支持的频段能力，省略上报仅和Pcell相关的频段组合能力。
步骤509：终端上报第三能力信息，该第三能力信息包括：
(a)测量能力：上报仅和当前主小区相关的测量能力；
上报的主小区相关的测量能力和步骤402中终端上报的主小区相关的频段和频段组合相对应。
(b)指示信息：用于通知网络设备，该能力消息只上报了和主小区相关的频段和频段组合的测量能力，未上报所有频段组合的测量能力，切换小区后需要再查询终端的测量能力。
示例性的，指示消息可以是MeasurementCapabiltyOnlyPcellRelated，可通过1比特False(F)或True(T)进行指示。
步骤510：记录测量能力信息。
网络设备根据终端之前(步骤402)上报的能力信息进行查询，将终端上报的频段能力中与主小区相关的频段、频段组合和步骤509(a)中终端上报的主小区相关的测量能力顺序对应，从而确定当前主小区所在频段和频段组合的测量能力，并进行记录。
根据终端上报的能力信息中的指示信息MeasurementCapabiltyOnlyPcellRelated：True，网络设备可知道终端上报的测量能力只上报了和主小区相关的频段和频段组合的测量能力。因此网络设备需要将终端之前上报的能力信息中与当前主小区相关的频段能力、频段组合能力按顺序与步骤509(a)中终端上报的仅和当前主小区相关的测量能力相对应，从而确定当前主小区所在频段和频段组合的测量能力。并且，网络设备会对终端已经上报过的测量能力信息进行记录，在重新接入/切换到主小区频段相同的小区后，不用再查询该终端的测量能力。
在该实施例中，通过省略上报终端支持的频段能力，省略上报仅和Pcell相关的频段组合能力，可以进一步节省测量能力上报的消息量，提升测量能力上报的成功率。本申请实施例，除了在测量能力消息中省掉了大量其他与主小区不相关的频段组合的测量能力的上报，并且利用终端上报的能力消息中已包含终端支持的频段和频段组合信息，该部分字段信息也不再上报。由网络设备根据已经上报的终端能力信息进行查询，将终端上报的测量能力和之前终端在能力信息中上报过的频段和频段能力顺序对应，从而确定主小区所在频段和频段组合的测量能力。可进一步节省测量能力上报的消息量，提升测量能力上报的成功率。
本申请还提供一种芯片或者芯片系统1400，如图6所述，芯片系统1400包括基带处理器1401，收发器或者接口1402，存储器1403等，其中，接口1402用于接收代码指令，并将接收的代码指令发送至处理器1401，处理器1401运行接收到的所述接口发送的所述代码指令，执行本申请实施例提升测量能力上报方法和装置，具体的终端设备测量测量能力上报方法可以参见本申请的实施例，在此不再赘述。
