具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下文所描述的本申请实施例的技术方案可以应用于如图1所示的网络架构，其中，图1仅是通信系统的一种示例，该通信系统可以包括至少两个网络设备，图1以包括2个网络设备为例，图1中的网络设备A和网络设备B之间可以直接或者间接(例如通过图中的核心网CN设备)的进行信息的交互。可以理解的是，图1中的网络设备的数量只是举例，通信系统中可以有更多的网络设备，任意一个网络设备可以为处于覆盖范围内的终端设备提供服务。
其中，终端设备是一种具有无线收发功能的设备，可以是固定设备、移动设备、手持设备、穿戴设备、车载设备，或内置于上述设备中的装置(例如，通信模块或芯片系统等)。所述终端设备用于连接人、物、机器等，可广泛用于各种场景。有时也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、物联网(internet of things，IoT)系统中的无线终端，无人驾驶(self driving)中的无线终端、远程医疗(remote medical) 中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、车载通信装置，车载通信处理芯片，可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等。应理解，本申请对于终端设备的具体形式不作限定。
其中，网络设备可以是接入网设备，接入网设备也可以称为无线接入网(radio access network，RAN)设备，是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备，也可以认为是一种为终端设备提供无线通信功能的设备。接入网设备例如包括但不限于：5G中的下一代基站(generation nodeB，gNB)、演进型节点B(evolved node B，eNB)、基带单元(baseband unit，BBU)、收发点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、未来移动通信系统中的基站或WiFi系统中的接入点等。接入网设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)，和/或分布单元(distributed unit,DU)，或者网络设备可以为中继站、车载设备以及未来演进的PLMN网络中的网络设备等。
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。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。例如其中一种可能的划分方式是：CU用于执行无线资源控制(Radio Resouce Control,RRC)层、业务数据适配协议(service data adaptation protocol，SDAP)层以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，而DU用于执行无线链路控制(radio link control，RLC)层，媒体接入控制(media access control，MAC)层，物理(physical)层等的功能。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。上图所示的网络架构可以应用于5G通信系统，其也可以与LTE系统共享一个或多个部件或资源。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 panel，CP)和用户面(user panel，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，共同完成接入网设备的功能。CU-CP和CU-UP之间的接口可以成为E1接口。
终端设备可以与不同技术的接入网设备进行通信，例如，终端设备可以与支持长期演进(long term evolution，LTE)的接入网设备通信，也可以与支持5G的接入网设备通信，还可以同时与支持LTE的接入网设备以及支持5G的接入网设备进行通信。本申请实施例并不限定。
下面结合附图介绍本申请实施例中用来实现上述方法的装置。因此，上文中的内容均可以用于后续实施例中，重复的内容不再赘述。为了实现上述本申请实施例提供的方法中的各功能，各网元或者装置可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
如图2所示，本申请一实施例提供了一种通信方法，该通信方法用于实现移动性负载均衡，因此，也可以称为移动性负载均衡的方法，该方法可以包括：
S201，第一网络设备向第二网络设备发送第一消息，请求获取该第二网络设备的资源状态报告。
例如，第一网络设备为了实现负载均衡或其他原因，想要了解第二网络设备的资源使用状态(即请求获取第二网络设备的资源状态报告)，可以生成并向第二网络设备发送第一消息。为便于说明，本申请实施例中，可以将获取资源状态报告称为负载测量。
其中，该第一消息例如可以是资源状态请求(resource status request)消息。
可以理解的是，第一网络设备在请求获取资源状态报告时，可能想要了解的资源状态报告粒度不同，也就是所请求的测量对象可能存在不同的粒度，那么负载测量可以更精确。所请求的测量对象可能包括以下至少一种粒度：基站(节点)粒度、小区粒度、波束粒度、切片粒度或者带宽部分(bandwidthpart,BWP)粒度。其中，波束可以理解为空间资源，可以指具有能量传输指向性的发送或接收预编码向量。并且，该发送或接收预编码向量能够通过索引信息进行标识，所述索引信息可以对应配置终端的资源标识(identity，ID)，比如，所述索引信息可以对应配置的CSI-RS的标识或者资源；也可以是对应配置的SSB的标识或者资源；也可以是对应配置的上行探测参考信号(Sounding Reference Signal，SRS)的标识或者资源。可选地，所述索引信息也可以是通过波束承载的信号或信道显示或隐式承载的索引信息。所述能量传输指向性可以指通过该预编码向量对所需发送的信号进行预编码处理，经过该预编码处理的信号具有一定的空间指向性，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等；所述能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。
一些可能的实现方式中，该第一消息中可以包括测量对象信息，根据所请求的测量对象的粒度不同，该测量对象信息的内容可能有所不同。举例而言，对于基站粒度的测量对象，那么对应的测量对象信息可以为空，测量对象缺省为该基站下所有小区；对于一个小区粒度的测量对象，对应的测量对象信息可以为至少一个小区标识(小区列表)；对于波束粒度的测量对象，对应的测量对象信息为至少一个小区标识和该至少一个小区标识对应的小区下的至少一个波束标识信息；对于切片粒度的测量对象，对应的测量对象信息为至少一个小区标识和该至少一个小区标识对应的小区下的至少一个切片标识信息。例如，第一网络设备想要了解第二网络设备的小区1，小区2以及小区3的波束2的资源使用状态，那 么测量对象信息中可以包括小区1的标识(cell ID1)、小区2的标识(cell ID2)和小区3的标识加上小区3的波束2的标识(例如cell ID3+SSB index 2)。需要说明的是，以上各个粒度为举例说明，也可以存在其他不同的粒度，本申请实施例对此不作限定，通过相应的标识可以指示出对应的粒度，例如，小区粒度对应的标识为小区的标识，波束粒度对应的标识为小区的标识和波束的索引、切片粒度对应的标识为小区的标识和切片的标识，BWP粒度对应的标识为小区的标识和BWP的标识。可以理解的是，第二网络设备可以根据第一网络设备的配置的测量对象信息进行相应的测量，而通过第一网络设备配置不同粒度的测量对象，可以使得负载测量更加精确和灵活。
可选的，该第一消息中还可以包括请求的资源状态报告的类别信息，也就是说在第一消息中可以指示第一网络设备想要获取哪些种类的资源的使用状态信息，资源的种类例如可以包括但不限于空口资源、传输网络层(transport network layer，TNL)资源、硬件资源、RRC连接数信息、激活的终端设备数量、总体可用资源、切片可用容量中的至少一种。进一步的，上述各个资源可以区分上行和下行方向，那么第一网络设备可以请求上行方向和/或下行方向的资源状态报告。又一种可能的实现方式中，第一网络设备在请求资源状态报告时，也可以不区分上行或者下行方向，由第二网络设备选择将上行和/或下行方向的资源状态报告发送给第一网络设备。可选的，本申请实施例中的上行方向可以包括辅助上行(supplementary uplink，SUL)。
可以理解的是，第二网络设备可以根据第一网络设备的配置的类别信息进行相应的测量，而通过第一网络设备配置请求的资源状态报告的类别，使得网络设备能够获得的资源状态报告信息更丰富。可选的，也可以是不通过第一网络设备配置类别信息，而是默认上报至少一种类别的资源的使用状态信息，或者第二网络设备决定上报至少一种类别的资源的使用状态信息。
其中，空口资源的具体形式例如可以为物理资源块(physical resource block，PRB)或者无线资源状态(radio resource status),可以用上行和下行的保证比特速率(guaranteed bit rate,GBR)的PRB和不保证速率(Non-GBR)的PRB的使用百分比表示；TNL资源,例如可以通过提供的TNL百分比或者可用的TNL百分比表示；硬件资源可以通过硬件可用容量表示；RRC连接数量可以用通过RRC连接的数量或者RRC连接可用百分比表示；激活的UE数量可以是指当前被激活的UE的数量；总体可用资源可以通过可用容量(composite available capacity,CAC)表示，而可用容量可以用容量等级或者可用容量百分比表示，其中，可用容量百分比可以包括小区总容量可用百分比和/或每个波束容量可用百分比；切片可用容量表示的是每个切片的可用容量；激活的终端设备数量可以是每个小区激活的终端设备的数量；RRC连接数信息可以是RRC连接数量和/或RRC连接可用百分比。一种可能的实现方式中，可以通过点阵或者位图(bitmap)的形式指示请求获取哪些种类的资源的使用状态信息，比如该点阵或者位图中包括至少一个比特位，每位代表一种资源，比特位为“1”表示请求获取该比特位对应的资源的使用状态信息，比特位为“0”表示未请求获取该比特位对应的资源的使用状态信息，本申请实施例对比特位如何取值的方式不做限定。上述粒度适用于此处的全部或者部分种类的资源。可以理解的是，第一网络设备可以针对不同的测量对象请求不同种类的资源对应的资源状态报告。
可选的，该第一消息中也可以包括上报周期(也可以称为报告周期)信息，该上报周 期信息表示资源状态报告的上报周期。其中，该上报周期例如可以设置成500毫秒或者其他数值，本申请实施例对此不做限定。如果该第一消息中没有指示上报周期的信息，那么第二网络设备可以只上报一次资源状态报告或者根据其他信息(例如下文描述的事件信息)决定何时发送至少一次资源状态报告。可以理解的是，该上报周期信息可以指示一个或者多个上报周期。当配置的是一个上报周期时，那么第二网络设备上报资源状态报告的周期不会动态变化；当配置的是多个上报周期时，那么第二网络设备上报资源状态报告的周期可能会动态变化，例如该多个上报周期可以分别与第二网络设备的不同的资源使用情况(负载)对应，从而在不同的负载下可能应用不同的上报周期，使得上报周期的应用更为合理和灵活。举例而言，假设第一消息中包括两个上报周期的信息，period 1(可用资源小于50％时使用)和period 2(可用资源大于或者等于50％使用)，其中，period 1的长度小于period 2的长度，那么第二网络设备在可用资源小于50％时可以按照period 1上报资源状态报告，在可用资源大于或者等于50％时可以按照period 2上报资源状态报告。需要说明的是，period 1也可以适用于可用资源等于50％的情况，也就是说对于临界值的情况不做限定。该上报周期可以适用于上述各个种类和/或粒度的资源。例如可以是所有种类和/或粒度的资源共用一个上报周期，也可以配置不同的上报周期，每个上报周期对应一个或多个种类和/或粒度的资源。
一些可能的实现方式中，第一消息中还可以包括测量标识，以标识本次测量。
可以理解的是，上述测量对象信息、上报周期信息、类别信息、测量标识是可选的信息。此外，第一消息中也可以包括测量周期的信息、触发资源状态报告的事件信息、超载门限信息中的至少一个。
其中，测量周期信息指示第二网络设备测量资源使用情况的周期，也可以理解为指示第二网络设备多久获取一次资源状态报告或者多久进行一次负载测量。其中，与上报周期信息类似，该测量周期的信息也可以指示一个或者多个测量周期。可以理解的是，本申请实施例不限制测量周期和上报周期的长短关系，一种可能的实现方式中，测量周期的长度可以小于上报周期的长度。此外，当没有配置测量周期或者测量周期为0的情况下，第二网络设备可以只执行一次测量或者按照默认的周期或者其他方式进行测量，本申请实施例对此不做限定。
可选的，与上报周期类似的，测量周期也可以分别与第二网络设备的不同的资源使用情况(负载)对应，从而在不同的负载下可能应用不同的测量周期。举例而言，假设第一消息中包括两个测量周期的信息，period 3(可用资源小于50％时使用)和period 4(可用资源大于或者等于50％使用)，其中，period 3的长度小于period 4的长度，那么第二网络设备在可用资源小于50％时可以按照period 3进行测量，在可用资源大于或者等于50％时可以按照period 4进行测量。
可选的，可以通过有效时间或者有效次数来控制测量周期的时效，例如，测量周期在有效时间超时后失效，或者测量周期在第二网络设备周期性测量次数达到有效次数后失效。在测量周期失效后，第二网络设备停止周期性测量。可以理解的是，第二网络设备可以在接收到第一消息后或者在启动第一次周期性测量后启动定时器或者计数器来控制测量周期的时效。其中，上述有效时间或者有效次数可以通过第一网络设备进行配置，例如将有效时间或者有效次数的信息携带在第一消息或者其他消息中由第一网络设备向第二网络设备 发送；或者，上述有效时间或者有效次数是预设的或者默认的数值。本申请实施例对有效时间或者有效次数的设置方式不做限定。
可以理解的是，第二网络设备可以根据测量周期实现周期性的测量，通过测量周期的配置，可以提高第二网络设备进行负载(资源使用情况)测量的有效性。可以理解的是，该测量周期可以适用于上述各个种类和/或粒度的资源，例如可以是所有种类和/或粒度的资源共用一个测量周期，也可以配置不同的测量周期，每个测量周期对应一个或多个种类和/或粒度的资源。
在通过第一消息配置了测量周期后，第二网络设备进行周期性测量。可选的，后续当需要停止周期性测量时，可以通过第一网络设备进行配置，使得第二网络设备停止周期性测量，从而可以对第二网络设备的测量行为进行灵活的控制。也就是说，可以由第一网络设备向第二网络设备发送指示停止周期性测量的信息。例如，通过专门的消息(即专门用于停止周期性测量的消息)由第一网络设备通知第二网络设备停止周期性测量，该专门的消息例如可以是停止消息。又例如，可以通过第一网络设备向第二网络设备发送指示测量周期为0的信息，从而实现指示周期性测量停止。和前文中第一消息中指示测量周期为0所不同的是，第一消息中是通过指示测量周期为0，实现一次测量，而此处的指示测量周期为0，是在根据第一消息进行周期性测量后的后续控制。可以理解的是，该指示测量周期为0的信息可以通过与第一消息不同(内容不同或者发送时机不同)的消息携带。可选的，为避免第二网络设备不清楚针对哪个测量停止周期性测量，在第一网络设备指示停止周期性测量时，还可以指示测量ID，从而使得第二网络设备能够准确的停止相应的移动性负载均衡测量。可以理解的是，此处的停止周期性测量的方法，可以和本申请实施例的其他步骤进行耦合(例如在S202或者S203或者S204之后，第一网络设备向第二网络设备指示停止周期性测量)，也可以独立于本申请实施例而单独实现(也就是说如何停止周期性测量不依赖于第一网络设备获取该第二网络设备的资源状态报告的具体流程)。
触发资源状态报告的事件信息用于配置第二网络设备在满足某个或者某些事件时，上报资源状态报告，该触发资源状态报告的事件信息包括但不限于已用资源门限信息、可用资源门限信息、预设时间内资源占用变化门限信息、资源分级基线信息中的至少一个。
其中，已用资源门限信息可以是绝对的门限值或者相对的门限信息，例如，绝对的门限值可以是百分比，那么当第二网络设备的已用资源的百分比大于或者等于配置的门限值时，会触发第二网络设备上报资源状态报告；而相对的门限信息可以是第二网络设备的已用资源相对于第一网络设备的已用资源的超出值门限，例如可以是10％，此外，该相对的门限信息也可以是第二网络设备的已用资源与第一网络设备的相对关系，例如第二网络设备的已用资源超过第一网络设备的已用资源。
与已用资源门限信息类似的，可用资源门限信息也可以是绝对的门限信息或者相对的门限信息，例如，绝对的门限信息可以是百分比，那么当第二网络设备的可用资源的百分比小于或者等于配置的门限值时，会触发第二网络设备上报资源状态报告。
预设时间内资源占用变化门限信息可以是预设的时间使用资源变化幅度的门限，用于判断第二网络设备在一段时间内使用资源的变化是否超过预设的幅度。该预设的时间可以是具体的时间段(例如10:00-11:00)，也可以是周期信息(可以称为变化周期)，也可以是从接收到第一消息后的一段时长信息。那么第二网络设备每隔预设的周期或者在配置的时 间段或者在一段时间内会判断使用资源的变化情况，从而确定是否触发上报资源状态报告。例如，假设配置的预设时间内资源占用变化门限信息为5分钟(min)内资源使用率变化幅度大于30％，那么第二网络设备可以在接收到第一消息后，判断5分钟内资源使用率变化值是否大于30％，如果5分钟内资源使用率变化值大于或等于30％的话，第二网络设备触发上报资源状态报告。
第一网络设备可以给第二网络设备配置资源分级的信息，也就是测量上报的分级数目(number of measurement reporting levels)，该分级数目例如可以配置为2,3,4,5,10中的任意一种，本申请实施例对分级数目不做限定，可以理解的是，分级数目也可以不通过第一网络设备配置，例如可以是默认的分级数目。该资源分级的信息用于确定将在超载门限以下(可选的，可以包含超载门限)的资源使用的情况分成几级，假设分级数目为4，超载门限是已用资源占比80％，那么资源使用情况会被分成4级，第1级为已用资源占比(资源使用率)为20％，第2级为已用资源占40％，第3级为已用资源占60％，第4级为已用资源占80％，那么第二网络设备在已用资源的变化跨越至少一级(例如从2级变成3级，或者从4级变成2级)的情况下，触发上报资源状态报告。然而，其实在负载较低的情况下，上报资源状态报告的必要性不高，例如资源使用率不论20％或者30％都可以理解为比较空闲的状态，相邻的网络设备(或者可以叫邻站)也许并不关心。那么为了减少不必要的上报，即减少信令交互的次数和开销，第一网络设备可以给第二网络设备配置资源分级基线的信息，该资源分级基线信息为启动资源分级的基线，即当第二网络设备使用的资源大于或者等于该基线时，第二网络设备启动根据资源使用的情况进行分级。例如，假设该资源分级基线为60％，仍然假设超载门限是已用资源占比80％，分级数目为4，那么第二网络设备可以在资源使用率达到60％时启用资源分级，该分级是在此基线基础上进行的，即资源使用率65％为1级，资源使用率70％为2级，资源使用率75％为3级，资源使用率80％为4级。也就是说，在配置了资源分级基线的情况下，第二网络设备在资源使用率在资源分级基线之上时，资源使用率变化跨越至少一级，会触发上报资源状态报告。可以理解的是，上述分级数目和资源分级基线可以结合使用，用于触发上报资源状态报告。可以理解的是，上述资源分级基线也可以是预设的数值或者也可以是由第二网络设备自己决定(例如可以根据网络状态或者负载情况决定)的数值，那么可以不用第一网络设备发送给第二网络设备。
上述的触发资源状态报告的事件信息可以适用于上述各个种类的资源，例如可以是所有种类的资源共用一个相同的事件信息，也可以每个事件信息对应一个或多个种类的资源。
可以理解的是，第二网络设备根据第一网络设备配置的触发资源状态报告的事件信息，在事件满足时进行资源状态报告的上报，可以使得第二网络设备的资源状态报告的上报更为合理，提高了上报的有效性。
可选的，第一网络设备也可以向第二网络设备发送超载门限的信息，该超载门限的信息指示用于确定第二网络设备是否超载的门限，从而使得第二网络设备可以判断何时超载并上报超载信息，使得第二网络设备的上报运作更有效，上报的信息也更丰富。如前所述，超载门限可以是已用资源占比的预设门限，在第二网络设备使用的资源大于或者等于该超载门限时，确定第二网络设备超载(认为第二网络设备进入超载)。此外，该超载门限也可以是可用资源占比的预设门限，那么在第二网络设备的可用资源小于或者等于该超载门限时，确定该第二网络设备超载。第二网络设备在进入超载(例如从之前的非超载状态变为 超载状态)时，可以触发上报资源状态报告，或者，第二网络设备在退出超载(即从之前的超载状态变为非超载状态)时，也可以触发上报资源状态报告。
该超载门限的信息可以适用于上述各个种类和/或粒度的资源。可以是所有种类和/或粒度的资源共用一个超载门限，也可以配置不同的超载门限，每个超载门限对应一个或多个种类和/或粒度的资源。
可以理解的是，在第一消息中各个信息，例如测量周期的信息、触发资源状态报告的事件信息、超载门限的信息、上报周期中的多个被配置给第二网络设备的情况下，可以共同对第二网络设备的资源状态的测量上报产生影响。例如，第二网络设备按照测量周期进行测量，在满足事件信息的情况下进行上报，此处不一一例举。此外，上述实施例以各个信息承载在第一消息中进行举例，一些可能的实现方式中，上述各个信息可以通过不同的消息进行传输，本申请实施例对此不做限定。
S202，第二网络设备向第一网络设备发送响应于第一消息的第二消息。
第二网络设备在接收到第一消息后，会根据第一消息的配置判断能否进行相应的测量。如果第二网络设备发现其中有一项或者多项资源无法测量，通过该第二消息指示获取资源状态失败，也就是说指示无法测量，该第二消息例如可以是资源状态失败(resource status failure)消息。如果第二网络设备能够根据第一消息的配置完成相应的测量，可以通过该第二消息指示能够发起(initiate)或者进行相应的测量(例如针对第一消息中指示的测量对象的测量)，该第二消息例如可以是资源状态响应(resource status response)消息，该资源状态响应消息可以表示各测量成功开始。在第二网络设备能够根据第一消息的配置完成相应的测量的情况下，执行S203及后续步骤。
S203，第二网络设备根据第一消息进行测量，获取资源状态信息。
第二网络设备在判断能进行相应的测量后，根据第一消息中的配置，对第一消息中的测量对象进行相应的测量(具体可以参考S201中的相关描述)，获取第二网络设备的资源使用情况并获取资源状态信息，进一步的，可以生成(获取)资源状态报告进行上报。可以理解的是，在第一消息中包括测量周期的信息的情况下，第二网络设备进行的是周期性的测量，在第一消息中包括超载门限时，第二网络设备在生成资源状态报告时会在资源状态报告中指示超载，也就是说在资源状态报告中包括超载的指示信息(overload flag)。需要说明的是，即使第一消息中不包括超载门限，第二网络设备也可以在生成资源状态报告时会在资源状态报告中指示超载，可以是第二网络设备自己定义或者确定超载门限。
S204，第二网络设备发送资源状态报告。
当第二网络设备获取资源状态报告后，可以立即向第一网络设备发送(上报)资源状态报告，也可以结合上报周期和/或事件决定何时向第一网络设备发送资源状态报告。
例如第二网络设备可以在每次上报周期到达时向第一网络设备发送资源状态报告，此外，第二网络设备也可以根据第一消息中的触发资源状态报告的事件信息判断发送资源状态报告的时机。可以理解的是，上报周期和该事件信息可以同时被配置并决定发送资源状态报告的时机，或者上报周期和该事件信息中的一个被配置，那么第二网络设备发送资源状态报告的时机取决于上报周期或者该事件信息。关于该事件信息如何触发第二网络设备发送资源状态报告，可以参考S201处的相关描述，此处不再赘述。
举例而言，假设第一消息中包括的测量周期的信息为50ms，上报周期的信息为200ms， 触发资源状态报告的事件信息为已用资源门限70％，测量对象信息为小区1的标识，小区2的标识和波束标识3，资源状态报告的类别信息为总体可用资源，那么表示第一网络设备向第二网络设备请求小区1的总体可用资源信息以及小区2的波束3的总体可用资源信息，并且测量周期为50ms，上报周期为200ms，并且配置的事件为总体可用资源小于或等于20％，那么第二网络设备以50ms的周期对小区1和小区2的波束3的总体可用资源进行测量，生成资源状态报告，且第二网络设备每200ms上报最近一次生成的资源状态报告，另外，第二网络设备还会在小区1的总体可用资源小于或等于20％和/或小区2的波束3的总体可用资源小于2等于70％时，向第一网络设备发送资源状态报告。可以理解的是，资源状态报告中指示小区1的总体可用资源和小区2的波束3的总体可用资源的信息。以上是以总体可用资源举例说明，对于其他种类的资源在实现上是类似的，不一一举例，需要说明的是，若第一消息中配置的资源状态报告的种类不止一种，那么在资源状态报告中会一一指示各个种类的资源信息，例如不同种类的资源通过不同的信元指示。
可选的，在第二网络设备判断资源超载的情况下，第二网络设备可以向第一网络设备发送指示超载的信息，从而向第一网络设备指示发生超载。可以理解的是，第二网络设备可以根据第一网络设备指示的超载门限信息确定第二网络设备的资源超载，而在第一网络设备没有指示超载门限信息的情况下，第二网络设备可以自己确定超载门限。进一步的，第二网络设备在向第一网络设备指示发生超载时，也可以向第一网络设备发送指示超载门限的信息，以便于第一网络设备清楚的获知第二网络设备的负载情况。
一些可能的实现方式中，指示超载的信息和超载门限也可以携带在资源状态报告中。
资源状态报告例如可以携带在资源状态更新消息中。
可以理解的是，如果第一网络设备和第二网络设备之间存在接口(例如Xn/X2/F1/E1接口)，那么上述第一消息、第二消息以及资源状态报告可以通过该接口进行传输。如果第一网络设备和第二网络设备之间没有接口，那么可能存在以下几种方式实现上述第一消息、第二消息以及资源状态报告在第一网络设备和第二网络设备之间的传输：(1)如图3所示，第一网络设备通过与核心网设备的接口(例如NG接口或者S1接口)将第一消息发送给核心网设备，核心网设备发送给第二网络设备，从而使得第二网络设备获知第一网络设备请求获取该第二网络设备的资源状态报告，相应的，第二消息和资源状态报告也可以通过第二网络设备和核心网设备之间的接口从第二网络设备传递给第一网络设备，(2)如图4所示，第一网络设备将第一消息发送给核心网设备1，核心网设备1将该第一消息发送给给核心网设备2，核心网设备2将第一消息发送给第二网络设备，相应的，第二网络设备将第二消息和资源状态报告发送给核心网设备2，核心网设备2将接收到的第二消息和资源状态报告发送给核心网设备1，核心网设备1发送给第一网络设备。
第一消息、第二消息和承载资源状态报告的消息可以是RRC消息，也可以是NAS消息，或者Container(容器)，根据不同的接口，消息的类型有所不同。
本申请实施例的方法，通过对使用资源的统计，测量和交互，让网元之间更准确地知道彼此的负载，从而可以进一步用于调整移动性参数，使得网元之间的负载均衡功能得到改进和加强，并且交互的流程更为简单直接且有效。特别地，对于系统间的负载交互流程更加有效。进一步的，网络设备之间的交互的移动性信息也可以更加丰富。
如图5所示，本申请实施例还提供了一种通信方法，也可以称为移动性负载均衡的方 法。该方法包括：
S501，第一网络设备向第二网络设备发送第三消息，请求改变移动性参数。
在移动性参数改变流程中，第一网络设备可以向第二网络设备发送第三消息，请求改变移动性参数。该第三消息例如可以是移动性改变请求消息。第一网络设备向第二网络设备发送第三消息的过程也可以理解为第二网络设备接收第一网络设备的移动性参数改变请求。
该第三消息中包括：第一小区的标识、第二小区的标识，以及第一移动性参数改变的事件信息，所述移动性参数包括所述第一网络设备和/或第二网络设备的移动性参数，其中，第一小区属于第一网络设备，第二小区属于第二网络设备。
可选的，在第三消息中还可以包括原因值，指示第一网络设备发起移动性改变请求的原因。此处的原因值例如可以是减少负载，本申请实施例对此不做限定。
可以理解的是，第一网络设备请求的移动性参数改变可以有不同的粒度，例如，包括以下至少一种粒度，小区粒度、波束粒度、切片粒度或者带宽部分(bandwidthpart,BWP)粒度。
通过在第三消息中携带第一标识，该第一标识与所请求的不同粒度的移动性参数改变的对象对应。例如，在第一网络设备请求的移动性参数改变是小区粒度时，第一标识中可以包括属于第一网络设备的至少一个小区的标识(第一小区的标识)以及属于第二网络设备的至少一个小区的标识(第二小区的标识)；在第一网络设备请求的移动性参数改变是波束粒度时，第一标识中可以包括第一小区的标识和第一小区的至少一个波束的索引(或者标识)以及第二小区的标识和第二小区的至少一个波束的索引。
上述第一移动性参数改变的事件信息也可以理解为移动性参数改变的规则。以移动性参数为切换门限举例，该第一移动性参数改变的事件信息与第一网络设备和/或第二网络设备的资源使用情况和切换门限关联，其中，第一网络设备和/或第二网络设备的资源使用情况和切换门限与移动性参数改变的粒度对应，或者说第一网络设备和/或第二网络设备的资源使用情况和切换门限指的是上述标识所对应的资源使用情况和切换门限。例如，在请求的移动性参数改变的粒度是小区粒度的情况下，第一网络设备的资源使用情况可以是第一小区的资源使用情况，第二网络设备的资源使用情况可以是第二小区的资源使用情况,那么切换门限可以是第一小区和/或第二小区对应的切换门限。
以请求的移动性参数改变的粒度是小区粒度的情况举例，该移动性参数改变的事件信息包括但不限于以下至少一种：
第二小区的已用资源每增加第一预设值，第二小区对应的切换门限减少第二预设值和/或第一小区对应的切换门限增加第三预设值；
第一小区的可用资源每增加第四预设值时，第二小区的对应的切换门限减少第五预设值和/或第一小区对应的切换门限增加第六预设值；
第一小区的可用资源大于或者等于第七预设值时，第二小区对应的切换门限不高于第八预设值和/或第一小区对应的切换门限不低于第九预设值。
需要说明的是，小区对应的切换门限，是指触发网络设备决定终端从服务小区切换到另一个邻区的门限。以上以小区粒度为例进行说明,对于其他粒度的场景，与此类似，本申请实施例不一一举例说明。此外，本申请实施例不限定移动性参数具体的改变规则，在本 申请实施例举例的基础上，可以进行任意变形，例如第二小区的可用资源每增加第十预设值，第二小区对应的切换门限增加第十一预设值和/或第一小区对应的切换门限减少第十二预设值，又或者，第二小区的可用资源比第一小区的可用资源多时，第二小区对应的切换门限不低于第十三预设值和/或第一小区对应的切换门限不高于第十四预设值。本申请实施例对第一至第十四预设值的取值不做限定。
此外，上文以移动性参数为切换门限进行举例，也可以是对其他移动性参数，可以理解的是，对其他移动性参数进行改变的规则与切换门限类似。
S502，第二网络设备向第一网络设备发送响应于第三消息的第四消息。
如果第二网络设备不接受(拒绝)第一网络设备的移动性参数改变请求，例如第二网络设备不同意第一移动性参数改变的事件信息，则第二网络设备在第四消息中向第一网络设备指示拒绝移动性参数改变，该第四消息例如可以为移动性改变拒绝消息。可选的，在第二网络设备不同意第一移动性参数改变的事件信息的情况下，在第四消息中还可以进一步包括第二网络设备所能接受或者所提出的移动性参数改变的事件信息(第二移动性参数改变的事件信息)，从而使得第一网络设备和第二网络设备之间能够更好的完成协商，提高效率。该第二移动性参数改变的事件信息可以是全部或者部分不同于第一移动性参数改变的事件信息，例如可以是基于第一移动性参数改变的事件信息进行调整后的新的移动性参数改变的事件信息，也可以是与第一移动性参数改变的事件信息中类型不同的新的移动性参数改变的事件信息，本申请实施例对第二移动性参数改变的事件信息不做限定。此外，在第四消息中还可以包括第二标识，该第二标识与第二移动性参数改变的事件信息所对应的对象对应，例如第二移动性参数改变的事件信息是与第一小区和第二小区对应的，那么，在第四消息中可以包括第一小区的标识和第二小区的标识。
如果第二网络设备接受第一网络设备的移动性参数改变请求，可以通过第四消息向第一网络设备指示第二网络设备接受第一网络设备的移动性参数改变请求，例如接受第一移动性参数改变的事件信息，该第四消息例如可以是移动性改变响应消息。可选的，在第四消息中可以包括第三标识，第三标识与第一标识可以是相同的标识。
可以理解的是，如果第一网络设备和第二网络设备之间存在接口(例如Xn/X2/F1/E1接口)，那么上述第三消息和第四可以通过该接口进行传输。如果第一网络设备和第二网络设备之间没有接口，那么可参考图3或者图4的方式实现上述第三消息和第四消息在第一网络设备和第二网络设备之间的传输。
第三消息和第四消息可以是RRC消息，也可以是NAS消息，或者Container，根据不同的接口，消息的类型有所不同。
可以看出，本申请实施例，通过引入基于事件的移动性参数改变，将移动性参数的改变与与第一网络设备和/或第二网络设备的资源使用情况和移动性参数关联，使得使得网络设备间的移动参数改变更为智能。进一步的，相对于对移动性参数的一次性调整的方案，通过本申请实施例的方案，信令也能得到减少。此外，本申请实施例的方案中，可以不只是小区粒度的移动性参数改变，也可以是其他粒度的移动性参数改变，使得移动性参数改变更为灵活和精细。
上述图2所示实施例的通信方法和图5所示实施例的通信方法，可以独立实施例，也可以结合。例如，可以是在按照图5所示实施例进行移动性参数调整并且按照图2所示实 施例获取资源状态报告，或者，也可以是第一网络设备在按照图2所示实施例获取资源状态报告后触发图5所示实施例的流程，本申请实施例对此不做限定。图5所示实施例的第一网络设备可以和图2所示实施例的第一网络设备是相同的网络设备，也可以是不同的网络设备，此外，图5所示实施例的第二网络设备可以和图2所示实施例的第二网络设备是相同的网络设备，也可以是不同的网络设备。
需要说明的是，本申请上述各个实施例中的第一网络设备和第二网络设备可以是相同制式(RAT)或不同制式的，或者，第一网络设备和第二网络设备可以属于同一个系统或者不同系统。
图6为本申请实施例提供的通信装置600的示意性框图。该通信装置600可以对应实现上述各个方法实施例中由网络设备(第一网络设备或第二网络设备)实现的功能或者步骤。该通信装置600可以为网络设备或者可以适用于该网络设备的部件(例如芯片或者电路等)或者，该通信装置600可以为芯片系统。本申请实施例中，芯片系统可以由芯片构成，也可以包含芯片和其他分立器件。
