下面详细介绍本申请涉及的通信系统以及装置。
本申请实施例的技术方案可以应用于各种通信系统，例如：码分多址(code division multipleaccess，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、长期演进(long termevolution，LTE)系统、通用移动通信系统(universal mobiletelecommunication system，UMTS)、第五代(5th generation，5G)系统或新无线(new radio，NR)，以及未来演进的无线通信系统等。
本申请实施例中的终端设备可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。无线终端也可以称为系统、订户单元(subscriber unit，SU)、订户站(subscriber station，SS)，移动站(mobile station，MB)、移动台(Mobile)、远程站(remote station，RS)、接入点(access point，AP)、远程终端(remote terminal，RT)、接入终端(access terminal，AT)、用户终端(user terminal，UT)、用户代理(user agent，UA)、终端设备(user device，UD)、或用户装备(user equipment，UE)等，本申请实施例对此并不限定。
本申请实施例中的网络设备又称为无线接入网(radio access network，RAN)设备，是一种将终端设备接入到无线网络的设备，具体可以为基站。基站可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。具体可以为：无线局域网(wireless local area network，WLAN)中的接入点(access point，AP)，全球移动通信系统(global system for mobile communications，GSM)或码分多址接入(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的基站(NodeB，NB)，还可以是LTE中的演进型基站(evolved Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及5G系统 中的下一代节点B(the next generation Node B，gNB)或者未来演进的公共陆地移动网(public land mobile network，PLMN)网络中的基站等，在此并不限定。一种可能的方式中，接入网设备可以是集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)分离架构的基站(如gNB)，如图1所示，图1为本申请一实施例提供的网络设备的协议栈示意图。RAN设备可以与核心网设备相连(例如可以是LTE的核心网，也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如无线资源控制(radio resource control，RRC)、业务数据适配协议栈(service data adaptation protocol，SDAP)以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能设置在CU，而无线链路控制(radio link control，RLC)，媒体接入控制(media access control，MAC)层，物理(physical，PHY)层等的功能设置在DU。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现也可以由不同的实体实现。例如，可以对CU的功能进行进一步切分，例如，将控制面(control plane，CP)和用户面(user plane，UP)分离，即CU的控制面(CU-CP)和CU用户面(CU-UP)。例如，CU-CP和CU-UP可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。一种可能的方式中，CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等。其中CU-CP和CU-UP通过E1接口连接。CU-CP代表gNB通过Ng接口和核心网连接。通过F1-C(控制面)和DU连接。CU-UP通过F1-U(用户面)和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。
需要说明的是，多种无线接入技术双连接(multi-RAT dual connectivity，MR-DC)中主基站和辅基站可以是上文所述网络设备的各种形式和结构。可选地，可能主基站和辅基站使用相同的CU而DU不同，或使用相同的DU而CU不同。
图2是本申请实施例的通信系统的一种示例。该通信系统中至少包括第一网络设备(gNB1)和第二网络设备(gNB2)。示例性地，该第一网络设备可以为分离架构的基站，例如，该第一网络设备可以包括一个CU和至少一个DU(图中仅示出2个)。该第二网络设备可以为分离架构的基站，例如该第二网络设备可以包括一个CU和至少一个DU(图中仅示出2个)。示例性地，该第一网络设备(gNB1)和第二网络设备(gNB2)可以通过Xn接口连接。
该第一网络设备和第二网络设备还可以与核心网连接。例如，第一网络设备还通过NG 接口与核心网连接，第二网络设备还通过NG接口与核心网连接。
在该通信系统中，第一网络设备与第二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，从而实现移动性负载均衡(mobility loading balance，MLB)。例如，第一网络设备和第二网络设备之间交互的资源可以包括传输网络层(transparent network layer，TNL)资源、硬件使用资源、天线负载以及总体资源情况等。
MLB是指过载的网络设备中的终端设备重新切换到轻载的网络设备，以平衡网络设备之间的负载。示例性地，网络设备之间可以基于各个接口实现MLB。例如，NG-RAN基站与核心网之间的NG接口、LTE基站和核心网之间的S1接口、NR基站之间的Xn接口，LTE基站之间的X2接口、CU与DU之间的F1接口以及CU-CP与CU-UP之间的E1接口等。示例性地，MLB的流程可以包括：移动性参数改变(Mobility Settings Change)和资源状态交互。移动性参数改变的流程如图3所示，下面对图3的各个步骤进行说明：
301，第一网络设备发送移动性参数改变请求，相应的，第二网络设备接收该移动性参数改变请求。
示例性地，该移动性参数改变请求(Mobility Change Request)用于指示第二网络设备调整第一切换触发门限，该第一切换触发门限是第二网络设备中的终端设备切换到第一网络设备的门限。第二网络设备接收到该移动性参数改变请求之后，对第一切换触发门限进行调整。例如，第二网络设备可以将该第一切换触发门限调高，使得第二网络设备中的终端设备可以驻留在第二网络设备中，而不是切换到第一网络设备。
示例性地，第一网络设备可以基于第一网络设备的资源使用情况或负载状态发送该移动性参数改变请求。例如，第一网络设备可以在第一网络设备处于重负载状态，或者第二网络设备处于轻负载状态的情况下，向第二网络设备发送上述移动性参数改变请求，指示第二网络设备调整第一切换触发门限，使得终端设备更多地驻留在第二网络设备，从而减轻第一网络设备的负载，平衡第一网络设备与第二网络设备之间的负载。
在一些实现方式中，上述移动性参数改变请求中还包括第二切换触发门限，该第二切换触发门限是第一网络设备中的终端设备切换至第二网络设备的门限。示例性地，在第一网络设备的可用资源小于第一阈值的情况下，第一网络设备可以将第二切换触发门限调低，使得第一网络设备中的终端设备可以切换到第二网络设备中，以减轻第一网络设备的负载。
302，第二网络设备发送移动性参数改变响应消息，相应的，第一网络设备接收该移动性参数改变响应消息。
示例性地，第二网络设备可以基于第二网络设备的资源使用情况确定是否接受第一网络设备对第一切换触发门限的调整。在第二网络设备接受第一网络设备对第一切换触发门限的调整的情况下，上述移动性参数改变响应消息可以包括移动性改变确定消息(Mobility Change Acknowledge)。在第二网络设备不接受第一网络设备对第一切换触发门限的调整的情况下，上述移动性参数改变响应消息可以包括移动性改变失败消息(Mobility Change failure)。例如，该移动性改变失败消息可以包括失败原因以及第二网络设备对第一切换触发门限的调整范围。
可理解，上述移动性参数改变请求可以是该第一网络设备基于资源状态交互结果发送的。例如，第一网络设备可以与该第二网络设备进行资源状态交互，以确定该第二网络设备的资源使用情况，从而基于该第二网络设备的资源使用情况发送该移动性参数改变请求。请参见图4，图4为本申请实施例提供的一种资源状态交互的交互示意图。下面对图4的各步骤进行说明：
401，第一网络设备发送资源状态请求消息，对应的，第二网络设备接收该资源状态请求消息。
示例性地，上述资源状态请求(resource status request)消息用于请求第二网络设备反馈至少一个资源参数的测量值，以进行资源状态交互。例如，该资源状态请求消息中的报告特征(Report Characteristics)信元中可以携带指示该至少一个资源参数的指示信息。
示例性地，上述至少一个资源参数可以是以该网络设备、小区、波束或者切片为粒度的，即该第一请求消息可以用于请求反馈该第二网络设备整体的至少一个资源参数的测量值，也可以用于请求反馈第二网络设备下的小区(cell)、波束(例如同步信号/物理广播信道块(SS(Synchronization Signal)/PBCH Block，SSB))或切片(slice)中的至少一个资源参数的测量值。例如，该资源状态请求消息中还包括该至少一个资源参数对应的小区、波束或切片的信息。
示例性地，第一网络设备可以在第一网络设备处于重负载状态的情况下，向第二网络设备发送该资源状态请求消息。
402，第二网络设备发送资源状态响应消息，对应的，第一网络设备接收该资源状态响应消息。
示例性地，第二网络设备接收到该资源状态请求消息之后，可以基于第二网络设备的可用资源确定是否能够反馈上述至少一个资源参数的测量值。在第二网络设备确定能够反馈该至少一个资源参数的测量值的情况下，向第一网络设备发送资源状态响应消息。
在步骤402中，第二网络设备发送该资源状态响应消息，第一网络设备接收该资源状态响应消息，从而完成第一网络设备和第二网络设备之间的资源状态交互初始化。在一些实现方式中，步骤402可替换为：第二网络设备发送资源状态失败消息，对应的，第一网络设备接收该资源状态失败消息。示例性地，第二网络设备接收到该资源状态请求消息之后，可以基于第二网络设备的可用资源确定是否能够反馈上述至少一个资源参数的测量值。在第二网络设备确定不能反馈该至少一个资源参数的测量值的情况下，向第一网络设备发送资源状态失败消息，以结束资源状态交互。
在一些实现方式中，图4所示的方法包括步骤403。
403，第二网络设备发送资源状态报告消息，对应的，第一网络设备接收该资源状态报告消息。
示例性地，该资源状态报告消息可以包括上述至少一个资源参数的测量值。第二网络设备接收到第一网络设备发送的资源状态请求之后，基于该资源状态请求开始测量至少一个资源参数的测量值，并通过资源状态报告消息将该至少一个资源参数的测量值反馈至第一网络设备。示例性地，该资源状态报告消息具体可以为资源状态更新(resource status update)消息。
示例性地，该资源状态请求包括周期信息，该周期信息用于指示该第二网络设备反馈该至少一个资源参数的测量值的反馈周期。例如，该周期信息可以包含于该资源状态请求消息的报告周期(Reporting Periodicity)信元中。第二网络设备可以基于该周期信息周期性测量该至少一个资源参数的测量值，并通过资源状态报告消息周期性地向第一网络设备反馈该至少一个资源参数的测量值。
示例性地，上述至少一个资源参数可以包括空口资源(physical resource block，PRB)的使用率、传输层资源(transport network layer，TNL)的使用率、总体可用资源(composite available capacity，CAC)的使用率、硬件资源(hardware capacity)的可用容量、切片资源状 态(Slice Radio Resource Status，SRRS)、激活UE数量(number of active UEs)、RRC连接数(RRC connections)、不同业务类型的负载大小中的至少一个。其中，空口资源使用率可以包括上下行的保障比特速率(guarantee bit rate，GBR)/非保障比特速率(Non-GBR)的使用率，传输层资源的使用率可以包括上下行TNL的使用率(即上下行可用的TNL百分比)，该总体可用资源的使用率可以包括上下行的可用容量百分比，该可用容量百分比可以包括小区总容量的可用百分比以及每个SSB容量可用百分比，该硬件资源使用率可以包括上下行的可用容量百分比，切片可用容量可以包括每个切片的可用容量。
可理解，上述至少一个资源参数仅为示例，本申请中的资源参数不限于上述几种示例，还可以包括随着技术防止出现的新的其他资源参数。因此，不应将上文所示的几种资源参数理解为对本申请实施的限定。应理解，本申请实施例中的资源参数可以是其对应的资源的使用率也可以是其对应的资源的可用量。例如，上述至少一个资源参数可以包括空口资源的可用量、TNL的可用容量、总体资源的可用量等中的至少一项。
在第一网络设备与第二网络设备进行资源状态交互时，第一网络设备可以根据自身的负载情况向第二网络设备发送资源状态请求，该资源状态请求用于请求第二网络设备反馈至少一个资源参数的测量值。第一网络设备可以基于第二网络设备反馈的至少一个资源参数的测量值确定是否将驻留在第一网络设备上的终端设备切换至第二网络设备。例如，在第一网络设备基于该一个或多个测量值确定该第二网络设备的整体资源使用率低的情况下，第一网络设备确定将驻留在第一网络设备上的终端设备切换至第二网络设备。在第一网络设备基于该一个或多个测量值确定该第二网络设备的整体资源使用率高的情况下，说明第二网络设备处于重负载状态，因此，第一网络设备确定不将驻留在第一网络设备上的终端设备切换至第二网络设备。
图4所示的方法中，在第二网络设备能够测量并反馈上述至少一个资源参数的情况下，第一网络设备与第二网络设备能够进行资源状态交互；在第二网络设备不能反馈该至少一个资源参数中的任一资源参数的测量值的情况下，第二网络设备会向第一网络设备发送资源状态失败消息，从而结束该资源状态交互。在第二网络设备不能反馈至少一个资源参数中所有的资源参数的测量值的情况下，第二网络设备也不会反馈该第二网络设备能够反馈的资源参数的测量值，而是会直接向第一网络设备发送资源状态失败消息，从而结束资源状态交互，因此该资源状态交互流程不灵活。且第一网络设备无法基于该资源状态失败消息确定第二网络设备的资源使用情况，第一网络设备会重新向第二网络设备发送资源状态请求，从而导致信令开销大，以及交互效率低。第一网络设备只能根据自身的需求重新发送资源状态请求，存在第二网络设备依旧无法成功反馈该资源状态请求请求反馈的资源参数的测量值的风险。
鉴于此，本申请实施例提供一种资源状态交互方法和通信装置，可以提高第一网络设备与第二网络设备之间的交互效率。本申请实施例提供的资源状态交互方法可以应用于图2所示的通信系统。或者该方法可以应用于第一网络设备和第二网络设备，该第一网络设备和第二网络设备可以是前文描述的网络设备。可理解，该第一网络设备和该第二网络设备可以是独立架构的gNB，也可以是分离架构的gNB-CU。
图5是本申请实施例提供的一种资源状态交互方法的交互示意图。如图5所示，该方法包括：
501，第一网络设备发送第一请求消息，对应的，第二网络设备接收该第一请求消息。
该第一请求消息包括第一指示信息，该第一指示信息用于指示至少一个资源参数的优先级，该第一请求消息用于请求反馈所述至少一个资源参数的测量值。
示例性地，上述至少一个资源参数包括空口资源的使用率、传输层资源的使用率、总体可用资源的使用率、激活用户设备UE数量以及RRC连接数中的至少一项。可以理解，上述至少一个资源参数的说明可以参见上文的描述，这里不再详述。该至少一个资源参数的测量值为第二网络设备对该至少一个资源参数进行测量得到的结果，例如，第二网络设备对其空口资源的使用率进行测量，得到该空口资源的使用率为60％，即该空口资源的测量值为60％。示例性地，该第一请求消息可以为第一网络设备发送的资源状态请求消息。
该第一指示信息用于指示第二网络设备按照该至少一个资源参数的优先级顺序对该至少一个资源参数进行测量。示例性地，该第一指示信息可以包括多位比特，该多个位比特中的每N位比特用于指示该至少一个资源参数中的一个资源参数的优先级，N为正整数。例如，该第一指示信息中的第一个N位比特的值指示该至少一个资源参数中的第一个资源参数的优先级。该N位比特的值与优先级的映射关系可以为：该N位比特的值越大，其指示的资源参数的优先级越高，或者该N位比特的值越小，其指示的资源参数的优先级越高。可以理解，上述N位比特的值与优先级的映射关系仅为示例，不应对本申请构成限制，例如该N位比特的值与优先级可以不成正比或者反比关系，只要不同级的优先级对应的N位比特的值不同即可。可理解，上述N位比特的值与优先级的映射关系可以由网络配置，也可以是协议规定的。
示例性地，上述N的值与至少一个资源参数的数量有关。例如，在该至少一个资源参数包括5个资源参数的情况下，该N的值可以为3，即该第一指示信息中的每3位比特用于指示一个资源参数的优先级。举例来说，至少一个资源参数包括空口资源的使用率、传输层资源的使用率、总体可用资源的使用率、激活UE数量以及RRC连接数，该第一指示信息的多位比特可以为101 100 011 010 001，其中第一个3位比特101指示空口资源的使用率的优先级，第二个3位比特100指示传输层资源的使用率的优先级，第三个3位比特011总体可用资源的使用率，第四个3位比特010指示激活用户设备UE数量，第五个3位比特001指示RRC连接数的优先级。
可以理解的是，在上述至少一个资源参数的数量为1的情况下，该至少一个资源参数不存在优先级关系，因此该第一请求消息中可以不包括该第一指示信息。
示例性地，第一网络设备可以基于其资源使用情况确定上述至少一个资源参数的优先级。例如，第一网络设备可以按照资源的使用率确定对应的资源参数的优先级。举例来说，在第一网络设备的空口资源的使用率高的情况下，第一网络设备期望将占用空口资源多的终端设备切换至该第二网络设备，因此第一网络设备可以将该空口资源的使用率确定为高优先级的资源参数。又如，在第一网络设备的处于RRC连接态的终端设备多，其空口资源的使用率不高的情况下，第一网络设备期望将有RRC连接的终端设备切换至该第二网络设备，因此第一网络设备可以将RRC连接数确定为高优先级的资源参数。
示例性地，该第一请求消息还包括用于指示该至少一个资源参数的指示信息。该指示信息可以包括第一比特位图(bitmap)，该第一比特位图的位数可以大于或等于第一网络设备可请求第二网络设备反馈其测量值的资源参数的数量。该第一比特位图中的每一位比特用于指示该第一请求消息是否请求反馈其对应的资源参数。举例来说，假设第一网络设备可请求第二网络设备反馈的资源参数包括空口资源的使用率、传输层资源的使用率、总体可用资源的使用率、激活用户设备UE数量以及RRC连接数五个，该第一比特位图至少包括5位比特，分别指示第一请求消息是否请求反馈上述五个资源参数的测量值。例如，若第一比特位图的内容为10010，则表示第一请求消息请求第二网络设备反馈空口资源的使用率和激活UE数量。
示例性地，该第一请求消息还包括第一反馈周期，该第一反馈周期用于指示该第二网络 设备反馈该至少一个资源参数的测量值的反馈周期，即第一反馈周期为第一网络设备希望第二网络设备反馈该指示一个资源参数的测量值的反馈周期。例如，该第一反馈周期可以为500ms、1000ms、2000ms、5000ms或10000ms，指示该第二网络设备可以每500ms、1000ms、2000ms、5000ms或10000ms反馈该至少一个资源参数的测量值。
示例性地，该第一请求消息还包括小区列表，该小区列表包括至少一个小区的信息。该至少一个小区为该至少一个资源参数对应的小区，即该第一请求消息用于请求该第二网络设备反馈该至少一个小区的至少一个资源参数的测量值。
示例性地，该第一请求消息还包括波束列表，该波束列表可以包括至少一个波束的信息，该至少一个波束为该至少一个资源参数对应的波束，即该第一请求消息用于请求该第二网络设备反馈该至少一个波束的至少一个资源参数的测量值。例如，该波束列表可以包括SSB列表。
示例性地，该第一请求消息还包括切片列表，该切片列表可以包括至少一个切片的信息，该至少一个切片为该至少一个资源参数对应的切片，即该第一请求消息用于请求该第二网络设备反馈该至少一个切片的至少一个资源参数的测量值。

示例性地，该第一请求消息还包括第一网络设备的标识以及该第二网络设备的标识。该第一网络设备的标识由第一网络设备分配，该第二网络设备的标识由该第二网络设备分配。

表2



502，第二网络设备根据优先级从至少一个资源参数中确定第一资源参数。
示例性地，该第一资源参数为第二网络设备能够反馈其测量值的资源参数。或者，该第一资源参数为第二网络设备完成测量的资源参数。
在一种实现方式中，第二网络设备在接收到该第一请求消息之后，可以基于该至少一个资源参数的优先级确定能够测量的资源参数，即确定第一资源参数。该第二网络设备确定该第一资源参数并测量第一资源参数的测量值。示例性地，在第二网络设备不能测量该至少一个资源参数中所有的资源参数的情况下，该第二网络设备优先测量该至少一个资源参数中优先级高的资源参数，因此该第一资源参数可以为该至少一个资源参数中优先级较高的资源参数。可理解，本申请实施例中的第一资源参数可以是一个资源参数，也可以是多个资源参数，本申请不做限定。
在另一种实现方式中，第二网络设备在接收到该第一请求消息之后，可以按照该优先级从高到低的顺序对该至少一个资源参数进行测量，从而确定该第一资源参数，并得到该第一 资源参数的。
在一种可能的实现方式中，上述第二网络设备根据优先级从至少一个资源参数中确定第一资源参数包括：第二网络设备根据优先级以及第二网络设备的可用资源从该至少一个资源参数中确定该第一资源参数。
示例性地，第二网络设备可以基于至少一个资源参数的优先级以及该第二网络设备的可用资源确定至少一个资源参数中能够测量的资源参数(即第一资源参数)。该第二网络设备在该可用资源允许的情况下，优先测量该至少一个资源参数中优先级高的资源参数，从而确定该第一资源参数。例如，第二网络设备可以按照优先级从高到低的顺序对该至少一个资源参数的测量值进行测量，第二网络设备可以不测量其可用资源不足以测量的资源参数，从而确定上述第一资源参数。举例来说，在第二网络设备的可用资源不足以测量该至少一个资源参数中优先级最高的资源参数，但是能够测量该至少一个资源参数中优先级次高的资源参数的情况下，第二网络设备可以不测量该优先级最高的资源参数的测量值，而测量该优先级次高的资源参数，因此上述第一资源参数不包括该优先级最高的资源参数，且包括该优先级次高的资源参数。本申请实施例中，第二网络设备基于上述优先级与第二网络设备的可用资源确定该第一资源参数，并完成对该第一资源参数的测量，可以合理利用有限的资源。
503，第二网络设备发送第一响应消息，对应的，第一网络设备接收该第一响应消息。
该第一响应消息包括上述第一资源参数的测量值。示例性地，第二网络设备在完成对该第一资源参数的测量之后，生成该第一响应消息，并将该第一响应消息发送至第一网络设备。
示例性地，该第一网络设备接收该第一响应消息之后，可以基于该第一资源参数的测量值确定该第二网络设备的资源使用情况，从而确定是否将该第一网络设备中的终端设备切换至该第二网络设备。
在图4所示的方法中，在第二网络设备不能反馈至少一个资源参数中所有的资源参数的测量值的情况下，第二网络设备向第一网络设备发送的资源状态失败消息，且该资源状态失败消息不包括第二网络设备能够反馈的资源参数的测量值，该第一网络设备不能基于该资源状态失败消息确定该第二网络设备的资源使用情况，使得第一网络设备与第二网络设备之间的资源状态交互效率低。而本申请实施例中，第一请求消息中包括用于指示至少一个资源参数的第一指示信息，以指示第二网络设备按照优先级从高到低的顺序测量该至少一个资源参数。可理解，至少一个资源参数中优先级较高的资源参数相对来说比较重要。该第一资源参数为该至少一个资源参数中已测量的资源参数。在该第二网络设备不能测量该至少一个资源参数中的所有资源参数，例如在第二网络设备的可用资源受限的情况下，第二网络设备优先测量优先级高的资源参数，并通过该第一响应消息反馈已测量的资源参数的测量值，保证该第一响应消息能够尽可能地反馈比较重要的资源参数的测量值，从而提高了第一网络设备与第二网络设备的资源状态交互效率，同时也提高了第一网络设备与第二网络设备之间的资源状态交互的灵活性。
为了更详细地解释上述第一响应消息，本申请实施例还提供以下几种情况。
情况一：该第二网络设备无法反馈该至少一个资源参数中所有资源参数的测量值。
在该种情况下，该第一响应消息可以包括如下几种示例：
示例一：该第一响应消息还包括第二指示信息，第二指示信息用于指示该至少一个资源参数中未反馈的资源参数或已反馈的资源参数。也就是说该第一响应消息可以包括第一资源参数的测量值以及该第二指示信息。
示例性地，该未反馈的资源参数可以是该第二网络设备无法测量的资源参数。例如，因该第二网络设备的可用资源不足而不能测量其测量值的资源参数。该已反馈的资源参数可以为该第二网络设备完成测量的资源参数，并反馈其测量值的资源参数。可理解，该第一响应消息包括该已反馈的资源参数的测量值。该已反馈的资源参数可以包括上述第一资源参数。
上述第二指示信息可以有如下几种实现方式：
实现方式一：该第二指示信息可以通过枚举的方式列举出该至少一个资源参数中未反馈的资源参数，或者列举出该至少一个资源参数中已反馈的资源参数。
实现方式二：该第二指示信息可以包括第二比特位图，该第二指示信息通过该第二比特位图指示该至少一个资源参数中未反馈的资源参数以及已反馈的资源参数。该第二比特位图的位数可以大于或等于该至少一个资源参数的数量，该第二比特位图中的每一位比特用于指示是否反馈其对应的资源参数。例如，该比特图中的一位比特的值为1，则表示该第一响应消息中已反馈该位比特对应的资源参数；该位比特的值为0，则表示该第一响应消息中未反馈该位比特对应的资源参数。举例来说，上述至少一个资源参数可以包括空口资源的使用率、传输层资源的使用率、总体可用资源的使用率、激活UE数量以及RRC连接数五个，则该第二比特位图可以包括5位比特，分别指示第一响应消息是否反馈上述五个资源参数的测量值。例如，该第二比特位图的内容包括10010，则表示第一响应消息反馈了空口资源的使用率和激活UE数量。
示例性地，该第一响应消息可以为资源状态失败消息，第二网络设备发送该第一响应消息以结束资源状态交互。该第一响应消息还可以包括失败原因。
举例来说，表3为本申请实施例提供的一种第一响应消息的示例。如表3所示，该第二指示信息可以包含于未反馈的资源参数(Unachievable Measurements)信元中，该未反馈的资源参数信元通过比特位图的方式指示该至少一个资源参数中已反馈的资源参数和未反馈的资源参数。该第一响应消息可以包括消息类型(Message Type)信元、第一网络设备标识(NG-RAN node1 Measurement ID)信元、第二网络设备标识(NG-RAN node2 Measurement ID)信元、原因(cause)信元以及关键诊断(Criticality Diagnostics)信元。示例性地，原因(cause)信元以及关键诊断(Criticality Diagnostics)信元可以参考协议3GPP TS 38.423 9.2.3.2和38.423 9.2.3.2。
表3

本申请实施例中，通过第二指示信息指示该至少一个资源参数中已反馈的资源参数或未反馈的资源参数，使得该第一网络设备可以基于该第二指示信息快速地该已反馈的资源参数或未反馈的资源参数，便于该第一网络设备后续基于该已反馈的资源参数或未反馈的资源参数执行的操作。
在一种可能的实现方式中，在第二指示信息用于指示未反馈的资源参数的情况下，该第一响应消息还包括第一时间信息，该第一时间信息用于指示该未反馈的资源参数的预计恢复反馈时间。即该第一响应消息可以包括上述第一资源参数的测量值、第二指示信息以及该第一时间信息。
示例性地，该第一时间信息可以包括至少一个时间，该至少一个时间分别用于指示该未反馈的资源参数的恢复反馈时间。例如，该至少一个时间中的每一个时间用于指示该未反馈的资源参数中的一个资源参数的预计恢复反馈时间。举例来说，该未反馈的资源参数包括五个资源参数，该至少一个时间可以包括五个时间，该五个时间分别用于指示对应的资源参数的预计恢复反馈时间。在本申请实施例中，第一响应消息可以通过该第一时间信息指示该未反馈的资源参数的预计恢复反馈时间，使得该第一网络设备在该预计恢复反馈时间之后再请求反馈该未反馈的资源参数的测量值，减小了第一网络设备再次请求反馈该未反馈的资源参数的测量值失败的可能性，使得该第一网络设备与第二网络设备之间的交互更加灵活。
在一种可能的实现方式中，在所述第二指示信息用于指示所述未反馈的资源参数的情况下，所述第二指示信息还用于指示所述未反馈的资源参数对应的小区、波束或切片，或者在所述第二指示信息用于指示所述已反馈的资源参数的情况下，所述第二指示信息还用于指示所述已反馈的资源参数对应的小区、波束或切片。
示例性地，该第一响应消息可以包括该未反馈的资源参数或已反馈的资源参数对应的小区、波束或切片的信息。上述第二指示信息可以包含于该小区、波束或切片的信息中。例如，第二指示信息包含于无法反馈的小区的信息中，该第二指示信息用于指示无法反馈的小区中已反馈的资源参数或未反馈的资源参数，该无法反馈的小区为该第一响应消息无法反馈其至少一个资源参数中所有资源参数的小区。举例来说，上述至少一个资源参数可以包括空口资源的使用率、传输层资源的使用率、总体可用资源的使用率、激活UE数量以及RRC连接数，则该第二指示信息中的第二比特位图可以包括5位比特，分别指示该无法反馈的小区中的五个资源参数的测量值是否已反馈。假设该第二比特位图的内容包括10010，则表示第一响应消息反馈了该无法反馈的小区的空口资源的使用率和激活UE数量，未反馈该无法反馈的小区的传输层资源的使用率、总体可用资源的使用率以及RRC连接数。
