Description

一种通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
目前通信机制中，如长期演进(long term evolution，LTE)和新无线(new radio，NR)中，网络设备之间可以交互资源使用情况，以优化网络移动性参数配置。
网络设备1可以通过如下方式获取网络设备2的资源使用情况：一种方式为，网络设备1向网络设备2发送移动性参数改变请求消息，并在接收到网络设备2发送的响应消息后可以确定网络设备2的资源使用情况。另一种方式为，网络设备1向网络设备2发送资源状况请求消息，并在接收到网络设备2发送的资源状态更新消息后获取网络设备2的资源使用情况。
但是由于新的通信协议中引入了增强型的移动性方案，如双活协议栈(dual active protocol stack，DAPS)和条件切换(conditional handover，CHO)，使得现有的资源交互机制无法精准地反应网络设备的资源使用情况，从而导致网络设备之间无法准确获知彼此的资源使用情况。进一步的，网络设备根据彼此的资源使用情况调整移动性参数时容易出错，进而影响移动性负载均衡(mobility loading balance，MLB)的效果。
发明内容
本申请提供一种通信方法及装置，用以解决在网络设备报告的资源使用情况不准确的问题。第一方面，本申请实施例提供了一种通信方法，包括：第一网络设备接收第二网络设备发送的资源状态信息，资源状态信息包括如下信息中至少一项：与DAPS相关的资源信息、与CHO相关的资源信息；第一网络设备基于资源状态信息确定第二网络设备的资源使用情况。

在一种可能的设计中，因CHO预留的资源的数量与即将接入的终端设备的数量(或者被确定为候选小区的次数或者回复CHO响应消息的次数)以及切换概率有关。通过上述设计，可以使第一网络设备可以对第二网络设备未来的资源使用情况有更精准的评估。
在一种可能的设计中，在第一网络设备接收第二网络设备发送的资源状态信息之前，方法还包括：第一网络设备向第二网络设备发送请求消息，请求消息用于请求第二网络设备测量资源使用情况，请求消息携带第三信息，第三信息用于指示第二网络设备测量与CHO相关的资源。上述设计中，通过将与CHO相关的资源作为一类测量的资源，从而第二网络设备可以根据第一网络设备的指示下测量与CHO相关的资源。
在一种可能的设计中，与CHO相关的资源信息，包括：M个类别的资源各自的CHO资源信息，其中，第一类别的资源的CHO资源信息包括如下信息中至少一项：因CHO即将释放的第一类别的资源的第一数量、因CHO而预留的第一类别的资源的第二数量，第一类别属于M个类别，M为大于0的整数。上述实现方式中，通过针对每个类别的资源均考虑CHO因素，可以提高资源测量报告的准确性。

具体实施方式
为了方便理解本申请实施例，下面介绍与本申请实施例相关的术语或背景：
1、移动性负载均衡(mobility loading balance，MLB)
现有通信机制中，如LTE和NR中，网络设备间交互资源使用情况，以优化网络移动性参数配置。
交互的内容可以有传输层资源、硬件使用情况、无线负载、总体资源情况等等。
下面以Xn为例，TS 36.423和TS 38.423中关于MLB有2个流程。一个流程是移动性参数改变时网络设备之间协商移动性参数。如图1所示，网络设备之间协商移动性参数的过程为：
S101，网络设备1向网络设备2发送移动性参数改变请求(Mobility Change Request)。
S102，网络设备2向网络设备1发送移动性参数改变确认/失败(Mobility Change Acknowledge/failure)。
移动性参数改变，这个过程的起因可以有很多，其中一种是两个网络设备交互了资源使用情况后，一个网络设备决定让另一个网络设备改变切换触发门限(Handover Trigger Change)，如网络设备1发现网络设备2很空闲，发送Mobility Change Request消息让网络设备2把切换触发门限调高，让更多的终端设备留在网络设备2，而不是切换到网络设备1。网络设备2如果接受网络设备1的请求，则Mobility Change Acknowledge。如果不接受，则Mobility Change Failure并带上原因和调整范围。网络设备1收到调整范围后可以会发起下一次请求。
另一个流程是资源状态报告初始化时相邻的网络设备交互资源使用情况，如图2所示，网络设备交互资源使用情况的过程为：
S201，网络设备1向网络设备2发送资源状态请求(Resource Status Request)。
S202，网络设备2向网络设备1发送资源状态响应/失败(Resource Status Response/Failure)。
S202，网络设备2在完成资源测量后向网络设备1发送资源状态更新(Resource Status Update)。
网络设备1想知道网络设备2的资源使用情况，可以发送资源状态请求消息让网络设备2开始对各种资源开始/停止/增加(某些小区)进行测量。如果网络设备2能成功把所有要求的资源都开始测量，则回复Resource Status Response。如果有一种无法开始测量，则回复Resource Status 2Failure。网络设备2在测量完网络设备1要求的各种资源后，就会发送测量报告给网络设备1。
3、切换(Handover)
在移动通信系统中，传统的切换流程中，连接态终端设备的移动性管理是由网络设备控制的，即网络设备通过发送切换消息指示终端设备切换到哪个小区以及如何进行切换。终端设备在接收到该切换消息后，根据切换消息中包含的内容，接入目标小区。如图3所示，切换流程包括：
S301，源网络设备向终端设备发送无线资源控制(radio resource control，RRC)重配消息，其中包含测量对象、报告配置、测量标识等参数。
S302，终端设备根据RRC重配置消息对一系列小区进行测量后，形成测量报告上报各类事件给当前连接的源网络设备，如当前服务小区的信号强度低于门限且目标小区信号高于门限。
S303，源网络设备进行切换决策，决定终端设备要不要切换。
如要切换，执行S304，源网络设备将发切换请求消息给目标网络设备。
S305，目标网络设备根据自身连接数等情况进行接入控制，决定要不要允许终端设备的接入。
如果允许，执行S306，目标网络设备发切换确认消息给源网络设备，其中包含新的小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)、目标网络设备安全相关算法等参数。
S307，源网络设备在收到目标网络设备发来的切换确认消息后，发送RRC重配置消息(切换命令)给终端设备，其中包含的内容来自S304的切换确认消息。具体的，NR系统中切换命令中可以包含目标小区的相关信息以及终端设备接入该目标小区所需的相关配置参数，例如，切换命令中包含目标小区的信息(如，目标小区的物理小区标识(physical cell identifier，PCI)以及目标小区对应的频率信息、目标小区为终端设备分配的C-RNTI、接入目标小区所需的随机接入信道(random access channel，RACH)资源信息等。
S308，终端设备根据切换命令对目标网络设备发起随机接入，并断开与源网络设备的连接。
S309，终端设备发送RRC重配置完成的消息给目标网络设备。
4、CHO
为提高切换成功率、鲁棒性，现有技术提出CHO机制。
示例性的，CHO过程可以如图4所示：
S401，源网络设备向终端设备发送RRC重配置消息，其中包含测量对象、报告配置、测量标识等参数。
S402，终端设备根据RRC重配置消息对一系列小区进行测量后，形成测量报告上报各类事件给当前连接的源网络设备，如当前服务小区的信号强度低于门限且目标小区信号高于门限。
S403，源网络设备向至少一个候选网络设备发送CHO请求。
S404，该至少一个候选网络设备向源网络设备分别发送CHO请求确认。
S405，源网络设备向终端设备发送RRC重配消息，该RRC重配消息携带多个候选小区分别对应的CHO配置信息。
CHO中，网络可以给终端设备配置一个或多个候选小区，若网络给终端设备配置多个候选小区，则网络可以通过一条RRC消息或者多条RRC消息给终端设备发送该多个候选小区分别对应的CHO配置信息。上述RRC消息可以重用现有的RRC重配消息，例如，该RRC消息可以是携带同步重配信元(reconfiguration with sync)的RRC重配消息，或者，该RRC消息也可以是携带移动性控制信息信元(mobility control info)的RRC连接重配消息)。CHO配置信息中可以包括CHO触发条件(或执行条件)、候选小区的相关信息(如，候选小区为终端设备分配的C-RNTI，接入候选小区所需的RACH资源信息，候选小区的全球小区识别码(cell global identification，CGI)，和/或，候选小区的PCI以及候选小区对应的频率信息，可选地，候选小区的相关信息还可以包括候选小区对应的资源信息(如物 理层配置参数、媒体介入控制(media access control，MAC)层配置参数、无线链路控制(radio link control，RLC)层配置参数、分组数据汇聚协议(packet data convergence protocol，PDCP)层配置参数、业务数据适配协议(service data adaption protocol，SDAP)层配置参数、RRC层配置参数等)。
另外，CHO触发条件(或执行条件)可以包括CHO执行事件类型和相应的门限值，CHO执行事件类型可以包括事件A3(邻区质量比特殊小区(special cell，Spcell)好一定的偏置offset)、事件A4(邻区高于一定的门限(threshold))、事件A5(Spcell低于threshold1且邻区高于threshold2)、事件B1(跨无线接入技术(radio access technology，RAT)(inter RAT)的邻区好于threshold)、事件B2(主小区(primary cell，PCell)低于threshold3且跨RAT的邻区高于threshold4)或其他执行事件类型等。一个候选小区可以被配置一个或多个CHO执行条件。
S406，终端设备根据该RRC重配消息，判断候选小区是否满足切换触发/执行条件，将满足切换触发/执行条件的候选小区作为目标小区。
具体的，终端设备可以根据CHO配置信息进行CHO触发/执行条件是否满足的判断。一种示例，例如，对应候选小区A，配置的CHO触发事件类型是A3事件，且配置的对应的门限值为第一阈值，则，当候选小区A的小区信号质量高于服务小区的小区信号质量第一阈值时，可以认为候选小区A满足CHO触发条件，该候选小区A可以被确定为目标小区，信号质量可以包括参考信号接收功率(reference signal received power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)、信号干扰噪声比(signal to interference plus noise ratio，SINR)中的至少一项，例如，信号质量包括RSRP和RSRQ，或者，信号质量包括RSRP和SINR，或者其他，对此不作限定)。另一种示例，例如，对应候选小区B，若配置的CHO触发事件类型是A5事件，且配置的对应的门限值为第二阈值、第三阈值，则当候选小区B的小区信号质量高于第二阈值，且服务小区的小区信号质量低于第三阈值时，可以认为候选小区B满足CHO触发条件，该候选小区B可以被确定为目标小区。
S407，终端设备与确定出的目标小区进行随机接入过程。
S408，终端设备向目标小区发送CHO完成消息，以通知目标网络设备条件切换完成。
5、DAPS
为减少切换过程中的中断时延，实现0ms中断，提出一种新的切换机制，称为DAPS机制。在DAPS机制中，终端设备在接收到切换消息后，保持与源接入网设备的连接，并建立与目标接入网设备之间的连接，直到目标接入网设备向终端设备发送释放指示，终端设备才断开与源接入网设备的连接。
1)对于下行链路(downlink，DL)：
源网络设备给终端设备发送切换消息后，可以继续给终端设备发送DL数据包，另外，源网络设备可以与目标网络设备之间进行DL数据转发。
终端设备收到切换消息后，保持与源网络设备的数据传输，即终端设备保持与源网络设备的连接，而且，终端设备建立与目标网络设备之间的连接。
2)对于上行链路(uplink，UL)：
终端设备接收到切换消息后，可以继续与源网络设备进行UL数据的传输，当在目标小区的RACH流程成功，终端设备开始与目标网络设备进行数据传输。终端设备会在一段 时间内与源网络设备和目标网络设备同时连接，直到目标网络设备给终端设备发送释放指示，终端设备才断开与源网络设备的链接。
需要说明的是，随着技术的不断发展，本申请实施例的术语有可能发生变化，但都在本申请的保护范围之内。
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
本申请实施例提供的通信方法可以应用于图5所示的通信系统中，该通信系统可以包括两个网络设备，还可以包括终端设备，其中，该两个网络设备可以基于Xn、X2、F1、E1等接口进行连接。应理解，图5仅是一种示例性说明，并不对通信系统中包括的终端设备、网络设备的数量进行具体限定。

本申请实施例中所涉及的网络设备，是网络侧的一种用于发射或接收信号的实体。例如，网络设备可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB)，还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。网络设备可以覆盖1个或多个小区。
示例性的，接入网设备可以根据协议栈功能拆分为两个部分：集中单元(centralized unit，CU)和分布单元(distributed unit，DU)。其中，一个接入网设备可以包含一个CU、以及至少一个DU，如图6所示。CU与至少一个DU连接，可以用于管理或者控制该至少一个DU。这种结构可以将通信系统中接入网设备的协议层拆开，其中部分协议层功能在CU中 实现，剩下部分或全部协议层功能分布在DU中实现，由CU集中控制DU。以接入网设备为gNB为例，gNB的协议层包括无线资源控制(radio resource control，RRC)层、业务数据适配协议(service data adaptation protocol，SDAP)层、分组数据汇聚协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体访问控制子层(media access control，MAC)层和物理层。其中，示例性的，CU可以用于实现RRC层、SDAP层和PDCP层的功能，DU可以用于实现RLC层、MAC层和物理层的功能。本申请实施例不对CU、DU包括的协议栈做具体限定。CU和DU之间可以采用F1接口进行连接，CU与其他的接入网设备采用Xn接口连接，CU与5G核心网(5G Core，5GC)之间采用NG接口连接，如图7所示。

本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
目前通信机制中，如LTE和NR中，网络设备之间可以交互资源使用情况，以优化网络移动性参数配置。
网络设备1可以通过如下方式获取网络设备2的资源使用情况：一种方式为，网络设备1向网络设备2发送移动性参数改变请求消息，并在接收到网络设备2发送的响应消息后可以确定网络设备2的资源使用情况。另一种方式为，网络设备1向网络设备2发送资源状况请求消息，并在接收到网络设备2发送的资源状态更新消息后获取网络设备2的资源使用情况。但是由于新的通信协议中引入了增强型的移动性方案，如DAPS和CHO，使得现有的资源交互机制无法精准地反应网络设备的资源使用情况，从而导致网络设备之间无法准确获知彼此的资源使用情况。进一步的，网络设备根据彼此的资源使用情况调整移动性参数时容易出错，进而影响MLB的效果。
例如，网络设备2向网络设备1发送资源状态更新消息后，有一些终端设备断开与网络设备2的连接，从而导致网络设备1获取的网络设备2的无线资源、RRC连接数和终端设备数量等指标的虚高，从而不合理的调高该源网络设备的切换门限。又例如，网络设备2向网络设备1发送资源状态更新消息后，有一些终端设备接入网络设备，从而导致网络设备1获取的网络设备2的无线资源、RRC连接数和终端设备数量等指标比实际低，从而不合理的降低该源网络设备的切换门限。
基于此，本申请实施例提供一种通信方法及装置，该通信方法可以为一种资源状态指示方法、资源状态获取方法、移动性负载均衡方法、移动性负载均衡参数指示方法、移动性负载均衡参数获取方法等等，用以解决在网络设备报告的资源使用情况不准确的问题。 其中，方法和装置是基于同一发明构思的，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。
应理解，本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一(项)个”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b或c中的至少一项(个)，可以表示：a，b，c，a和b，a和c，b和c，或a、b和c，其中a、b、c可以是单个，也可以是多个。
应当理解，在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
另外，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
下面结合附图对本申请提供的通信方法进行具体说明。
如图9所示，为本申请实施例提供的一种通信方法，该方法具体可以包括：
S901，第二网络设备进行资源测量，得到资源状态信息，资源状态信息包括如下信息中至少一项：与DAPS相关的资源信息、与CHO相关的资源信息。
示例性的，第二网络设备可以以网络设备为粒度进行资源测量，即第二网络设备可以对自身的各项资源进行统计，因此，得到的资源状态信息的粒度为网络设备粒度的。例如，若第二网络设备为基站，则资源状态信息的粒度为基站粒度的。又例如，若第二网络设备为CU，则资源状态信息的粒度为CU粒度的。又例如，若第二网络设备为DU，则资源状态信息的粒度为DU粒度的。
或者，第二网络设备也可以以小区为粒度进行资源测量，即第二网络设备可以对每个属于第二网络设备的小区的各项资源进行统计，因此，得到的资源状态信息的粒度为小区粒度的。
又或者，第二网络设备也可以以波束(beam)或者同步信号/物理广播信道块(ss/pbch block，SSB)为粒度进行资源测量，即第二网络设备可以对第二网络设备的每个波束(或者每个SSB)的各项资源进行统计，因此，得到的资源状态信息的粒度为波束粒度的。
再或者，第二网络设备也可以以切片(slice)为粒度进行资源测量，即第二网络设备可以对第二网络设备的每个切片的各项资源进行统计，因此，得到的资源状态信息的粒度为切片粒度的。
此外，第二网络设备也可以采用小区组粒度进行资源测量，即第二网络设备针对每个小区组进行资源测量，其中，一个小区组包括至少一个属于第二网络设备的小区，第二网络设备的小区组的分组这里不做具体限定。又例如，第二网络设备也可以采用波束组粒度进行资源测量，即第二网络设备针对每个波束组进行资源测量，其中，一个波束组包括第二网络设备的至少一个波束，第二网络设备的波束组的分组这里不做具体限定。又例如， 第二网络设备也可以采用切片组粒度进行资源测量，即第二网络设备针对每个切片组进行资源测量，其中，一个切片组包括第二网络设备的至少一个切片，第二网络设备的切片组的分组这里不做具体限定。
当然，第二网络设备也可以采用其他粒度进行资源测量，这里不对第二网络设备进行资源测量时可能采用的粒度一一列举。
S902，第二网络设备向第一网络设备发送资源状态信息。相应的，第一网络设备接收第二网络设备发送的资源状态信息。
其中，第二网络设备可以通过Xn、X2、F1、E1等接口向第一网络设备发送资源状态信息。或者，第二网络设备也可以通过其他设备转发给第一网络设备，例如，第二网络设备将资源状态信息发给第一核心网，第一核心网再转发给第二核心网，再由第二核心网发送给第一网络设备，示例性的，第二网络设备为5G基站，第一网络设备为4G基站，第二网络设备可以将资源状态信息发给5G核心网(5G core，5GC)，5GC转发给核心分组网演进(evolved packet core，EPC)，由EPC转发给第一网络设备。
S903，第一网络设备基于资源状态信息确定第二网络设备的资源使用情况。
本申请实施例中，第二网络设备在向第一网络设备报告资源状态信息时，可以指示与DAPS相关的资源、与CHO相关的资源，使得第一网络设备根据第二网络设备报告的资源状态信息确定第二网络设备即将释放的资源、可能被占用的资源等，从而可以对第二网络设备的资源使用情况进行折算，以获取较为准确的资源使用情况，特别是对于未来预计的资源使用情况可以有更为精准的预估。第一网络设备根据第二网络设备即将释放的资源、可能被占用的资源等信息进行移动性负载均衡时可以提高负载均衡的准确性。例如，第一网络设备根据第二网络设备与DAPS相关的资源可以对第二网络设备的无线资源，RRC连接数和UE数量等指标值进行折算，从而可以降低第二网络设备的无线资源，RRC连接数和UE数量等指标虚高的程度，进而可以合理的调整该源网络设备的切换门限。
一个可能的实施例中，第二网络设备进行资源测量也可以是第二网络设备自己触发的，即第二网络设备主动测量报告资源状态信息。
另在一个可能的实施例中，在步骤S907之前，第一网络设备可以向第二网络设备发送请求消息，请求消息用于请求第二网络设备测量资源使用情况。在该实施例中，第二网络设备进行资源测量是在第一网络设备发送的请求消息触发的。
一种实现方式中，第一网络设备发送的请求消息可以是单次有效，第二网络设备在接收该请求消息后进行一次报告。
另一种实现方式中，第一网络设备发送的请求消息可以是多次有效，第二网络设备在接收该请求消息后可以周期性报告。
另一种实现方式中，第一网络设备发送的请求消息可以是多次有效，第二网络设备在接收该请求消息后基于某些条件/事件报告。如被测量的资源满足某种百分比。
可选的，第二网络设备收到上述请求消息后，可以根据里面的要求开始相关的测量，如果发现报告类别中有任一项资源无法测量，则回复资源状态失败(Resource status failure)消息给第一网络设备，否则，则回复资源状态响应(Resource status response)消息给第一网络设备。其中，该资源状态响应消息表示各测量成功开始，并没有测量完毕。
可选的，该请求消息中可以包括测量ID。
该请求消息中还可以包括报告类别列表，该报告类别可以用于指示哪些种类的资源需 要被测量并发送报告，如空口资源(Physical Resource Block or Radio resource status)、传输层(transparent network layer，TNL)资源(Transparent Network Layer Capacity)、硬件资源(Hardware Capacity Indicator)、切片可用容量、激活UE数量、RRC连接数、总体可用资源(Composite Available Capacity)等等。该报告类别可以是二进制的字符串，每个比特代表一种资源，可以通过比特的取值指示是否测量报告该类资源，例如，若一个比特取值为1表示需要测量报告该比特对应的资源，0表示不需要测量报告该比特对应的资源。
其中，空口资源可以为上下行的保证比特速率(guaranteed bit rate，GBR)/不保证比特速率(non-guaranteed bit rate，Non-GBR)的使用百分比等。传输层资源可以包括上下行提供的TNL、上下行可用的TNL百分比等。总体可用资源可以包括小区容量等级、可用容量百分比(如小区总容量可用百分比、每个SSB容量可用百分比等)。硬件资源可以包括上下行硬件可用容量等。切片可用容量可以包括每个切片可用容量等。RRC连接数可以包括RRC连接数、RRC连接可用百分比等。
该请求消息中还可以包括小区列表(哪些小区的资源需要被测量)、SSB列表(该小区下哪些波束需要被测量)、切片列表(该小区下哪些切片需要被测量)等。
该请求消息中还可以包括报告周期，例如，报告周期可以为500毫秒，从而第二网络设备可以每500毫秒报告一次。可选的，如果该请求消息中没有携带报告周期，第二网络设备可以报告一次。
该请求消息中可以携带DAPS指示信息，该DAPS指示信息用于指示第二网络设备测量上报与DAPS相关的资源。第二网络设备在接收到该请求消息后可以与DAPS相关的资源进行统计。相应的，资源状态信息中包括与DAPS相关的资源信息。例如，如图10所示。
一种实现方式中，该请求消息中可以携带用于指示测量与DAPS相关的资源的第一信息。示例性的，请求消息可以在报告类别中包括第一信息，也就是将与DAPS相关的资源作为一类测量的资源。例如，报告类别中可以包括一个比特，该比特用于指示是否测量报告与DAPS相关的资源。可以通过该比特的取值指示是否测量报告与DAPS相关的资源，例如，若一个比特取值为1表示需要测量报告与DAPS相关的资源，0表示不需要测量报告与DAPS相关的资源。
第二网络设备在接收到该请求消息后可以对如下至少一项进行统计：处于DAPS状态的终端设备的数量、处于DAPS状态的DRB的数量。相应的，与DAPS相关的资源信息，可以包括如下信息中至少一项：处于DAPS状态的终端设备的数量、处于DAPS状态的终端设备的占比、处于DAPS状态的DRB的数量、处于DAPS状态的DRB的占比。
一种举例说明中，假设第一网络设备在请求消息的报告类别中指示第二网络设备测量报告无线使用情况、RRC连接数和DAPS相关资源，第二网络设备向第一网络设备发送的资源状态信息可以如表1所示。
表1
无线使用情况
RRC连接数
DAPS相关资源
>处于DAPS的UE/DRB数量
>处于DAPS的UE/DRB比例
其中，无线使用情况、RRC连接数和DAPS相关资源是并列结构，处于DAPS的UE/DRB数量和处于DAPS的UE/DRB比例是DAPS相关资源的下一级子目录。
以资源测量的粒度为小区粒度为例，第二网络设备在接收到该请求消息后可以对如下至少一项进行统计：接入第一小区的终端设备中处于DAPS状态的终端设备的数量、接入第一小区的终端设备中处于DAPS状态的DRB的数量，其中，第一小区属于第二网络设备。相应的，与DAPS相关的资源信息，可以包括如下信息中至少一项：接入第一小区的终端设备中处于DAPS状态的终端设备的数量、接入第一小区的终端设备中处于DAPS状态的终端设备的占比、接入第一小区的终端设备中处于DAPS状态的DRB的数量、接入第一小区的终端设备中处于DAPS状态的DRB的占比，其中，第一小区属于第二网络设备。
以资源测量的粒度为网络设备粒度为例，第二网络设备在接收到该请求消息后可以对如下至少一项进行统计：接入第二网络设备的终端设备中处于DAPS状态的终端设备的数量、接入网络设备的终端设备中处于DAPS状态的DRB的数量。相应的，与DAPS相关的资源信息，可以包括如下信息中至少一项：接入第二网络设备的终端设备中处于DAPS状态的终端设备的数量、接入网络设备的终端设备中处于DAPS状态的终端设备的占比、接入网络设备的终端设备中处于DAPS状态的DRB的数量、接入网络设备的终端设备中处于DAPS状态的DRB的占比。
一个连接态的终端设备与网络设备相连的时候，数据是通过一个或者多个DRB进行传输的。终端设备在做切换时，可以以DRB为粒度选择是否使用DAPS方法。例如终端设备有三个DRB，在切换过程中，一种可能的情况为DRB1做DAPS，DRB2和DRB3做普通切换。因此，上述方法中第二网络设备通过以DRB为粒度统计与DAPS相关的资源，可以提高资源测量报告的准确性。
另一种实现方式中，该请求消息中可以携带用于指示测量备测量N个类别的资源各自与DAPS相关的资源的第二信息，N为大于0的整数。示例性的，第二信息可以指示第二网络设备在测量N个类别的资源时考虑DAPS因素，其中，N个类别的资源可以是该请求消息中携带的报告类别指示的资源。可选的，第二信息可以是隐式的，也可以是显式的，这里不做限定。
第二网络设备在接收到该请求消息后，可以针对每一类资源确定该类资源中与DAPS相关的资源数量。相应的，与DAPS相关的资源信息，可以包括：N个类别的资源各自与DAPS相关的资源数量。
可选的，空口资源、传输层资源、总体可用资源、硬件资源、切片可用容量、激活UE数量、RRC连接数等测量参数可以分别作为一种资源类别。或者，也可以多个测量参数作为一种资源类别，例如，空口资源和传输层资源作为一种资源类别，又例如，RRC连接数、硬件资源以及总体可用资源作为一种资源类别，等等。
一种举例说明中，假设第一网络设备在请求消息的报告类别中指示第二网络设备测量报告无线使用情况和RRC连接数，并携带指示考虑DAPS因素的第二信息，第二网络设备向第一网络设备发送的资源状态信息可以如表2所示。
表2
无线使用情况
>当前协议包括的信元
>与DAPS相关的无线使用情况
RRC连接数
>当前协议包括的信元
>进行DAPS的RRC连接数
其中，无线使用情况和RRC连接数是并列关系，与DAPS相关的两个信元与当前协议包括的信元是并列关系。
因为处于DAPS的终端设备在很多资源上的使用有别于正常情况下的终端设备，即会在一段时间内断开与源网络设备的连接。上述实现方式中，通过针对每个类别的资源均考虑DAPS因素，可以提高资源测量报告的准确性。
该请求消息中可以携带CHO指示信息，该CHO指示信息用于指示第二网络设备测量上报与CHO相关的资源。第二网络设备在接收到该请求消息后可以与CHO相关的资源进行统计。相应的，资源状态信息中包括与CHO相关的资源信息。例如，如图11所示。
一种实现方式中，该请求消息中可以携带用于指示测量与CHO相关的资源的第三信息。示例性的，请求消息可以在报告类别中包括第三信息，也就是将与CHO相关的资源作为一类测量的资源。例如，报告类别中可以包括一个比特，该比特用于指示是否测量报告与CHO相关的资源。可以通过该比特的取值指示是否测量报告与CHO相关的资源，例如，若一个比特取值为1表示需要测量报告与CHO相关的资源，0表示不需要测量报告与CHO相关的资源。
第二网络设备在接收到该请求消息后可以对如下至少一项进行统计：因CHO即将释放的资源、因CHO预留的资源。相应的，与CHO相关的资源信息，可以包括如下信息中至少一项：因CHO即将释放的资源的数量、因CHO预留的资源的数量。
其中，因CHO即将释放的资源可以为即将执行CHO的终端设备数量，也就是接收到如步骤S405的RRC重配消息但是还没有进行小区切换的终端设备。
示例性的，因CHO预留的资源的数量可以与即将接入的终端设备的数量(或者被确定为候选小区的次数或者回复CHO响应消息的次数)以及切换概率有关。第二网络设备在统计因CHO预留的资源时可以根据切换概率进行折算，例如，第二网络设备预留了1％的资源，切换概率为50％，因CHO预留的资源的数量可以为1％×50％＝0.5％。
或者，因CHO预留的资源的数量也可以为第二网络设备统计的资源数量，第一网络设备在接收到该因CHO预留的资源的数量后可以根据切换概率进行折算。
一种举例说明中，假设第一网络设备在请求消息的报告类别中指示第二网络设备测量报告无线使用情况、RRC连接数和CHO相关资源，第二网络设备向第一网络设备发送的资源状态信息可以如表3所示。
表3
无线使用情况
RRC连接数
CHO相关资源
>因CHO即将释放的资源的数量
>因CHO预留的资源的数量
其中，无线使用情况、RRC连接数和CHO相关资源是并列结构，即因CHO即将释放的资源的数量和因CHO预留的资源的数量是CHO相关资源的下一级子目录。
以小区粒度为例，第二网络设备在接收到该请求消息后可以对如下至少一项进行统计：即将由第一小区切换到第二小区的终端设备的数量、即将接入第一小区的终端设备的数量、第一小区被确定为候选小区的次数、第一小区回复CHO响应消息的次数，其中，第一小区属于第二网络设备，第二小区为除第一小区以外的其他小区，其中，第二小区可以属于第二网络设备，也可以属于第一网络设备，也可以属于其他网络设备。相应的，与CHO相关的资源信息，可以包括如下信息中至少一项：即将由第一小区切换到第二小区的终端设备的数量、即将接入第一小区的终端设备的数量、第一小区被确定为候选小区的次数、第一小区回复CHO响应消息的次数。
以网络设备粒度为例，第二网络设备在接收到该请求消息后可以对如下至少一项进行统计：即将由第二网络设备切换到其他网络设备的终端设备的数量、即将接入第二网络设备的终端设备的数量、第二网络设备被确定为候选网络设备的次数、第二网络设备回复CHO响应消息的次数。相应的，与CHO相关的资源信息，可以包括如下信息中至少一项：即将由第二网络设备切换到其他网络设备的终端设备的数量(相当于因CHO即将释放的资源的数量)、即将接入第二网络设备的终端设备的数量(相当于因CHO而预留的资源的数量)、第二网络设备被确定为候选网络设备的次数(相当于因CHO而预留的资源的数量)(相当于因CHO而预留的资源的数量)、第二网络设备回复CHO响应消息的次数(相当于因CHO而预留的资源的数量)。
另一种实现方式中，该请求消息中可以携带用于指示测量备测量M个类别的资源各自与CHO相关的资源的第四信息，M为大于0的整数。示例性的，第四信息可以指示第二网络设备在测量M个类别的资源时考虑DAPS因素，其中，M个类别的资源可以是该请求消息中携带的报告类别指示的资源。可选的，第四信息可以是隐式的，也可以是显式的，这里不做限定。其中，M个类别的资源可以参阅上述N个类别的资源的相关描述，这里不再重复赘述。
第二网络设备在接收到该请求消息后，可以针对每一类资源确定该类资源中与CHO相关的资源数量，例如，针对第一类别的资源，确定第一类别的资源如下信息中至少一项：因CHO即将释放的第一类别的资源的第一数量、因CHO而预留的第一类别的资源的第二数量，第一类别属于M个类别。相应的，与CHO相关的资源信息，可以包括：M个类别的资源各自的CHO资源信息，其中，第一类别的资源的CHO资源信息包括如下信息中至少一项：因CHO即将释放的第一类别的资源的第一数量、因CHO而预留的第一类别的资源的第二数量，第一类别属于M个类别。
以小区粒度为例，第二网络设备在接收到该请求消息后，可以针对第一小区的每一类资源确定该类资源中与CHO相关的资源数量，例如，针对第一小区的第一类别的资源，确定第一小区的第一类别的资源如下信息中至少一项：第一小区因CHO即将释放的第一类别的资源的第一数量、第一小区因CHO而预留的第一类别的资源的第二数量，第一类别属于M个类别。相应的，与CHO相关的资源信息，可以包括如下信息中至少一项：第一小区的M个类别的资源各自的CHO资源信息，其中，第一小区的第一类别的资源的CHO资源信息包括如下信息中至少一项：第一小区因CHO即将释放的第一类别的资源的第一数量、第一小区因CHO而预留的第一类别的资源的第二数量。

>>因CHO而预留的无线资源
RRC连接数

>CHO相关的RRC连接数
>>因CHO即将释放的RRC连接数
>>因CHO而预留的RRC连接数
其中，无线使用情况和RRC连接数是并列关系，CHO相关的信元与当前协议包括的信元是并列关系，具体的CHO展开信元是下一级。
在DAPS机制中，终端设备在接收到切换消息后与源网络设备的连接是暂时的，这部分资源虽然占用了，但是很快就会释放掉。本申请实施例中发送侧网络设备通过对这部分资源进行指示，使得接收侧网络设备可以对发送侧网络设备未来的资源使用情况有更精准的评估，从而接收侧网络设备可以更准确的获取发送侧网络设备的负载，进而可以提高网络负载均衡的准确性。
在CHO机制中，源网络设备提前给终端设备发送多个候选小区分别对应的CHO配置信息，终端设备收到CHO配置信息后，并不直接断开与源网络设备的连接，而是等某些条件满足了之后才执行切换到目标小区。在这段时间里，所有的候选网络设备都需要为该终端设备保留资源，这部分资源虽然没有终端设备在使用，但是也无法分配给其他终端设备，并且这部分资源在终端设备切换到目标小区后进行释放，本申请实施例中发送侧网络设备通过对这部分资源进行指示，使得接收侧网络设备可以对发送侧网络设备未来的资源使用情况有更精准的评估，从而接收侧网络设备可以更准确的获取发送侧网络设备的负载，进而可以提高网络负载均衡的准确性。
