Description

一种模型配置方法及装置 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种模型配置方法及装置。
背景技术
随着通信技术的发展和用户需求的提升，通信场景中的终端逐渐呈现大数量、多形态等特征。例如，工业自动化场景中，厂房中存在大量的监控设备、机器、或传感器等；家庭和生活场景中，存在大量手机、平板、穿戴式设备、智能家电、或车载终端等各种类型的终端。为便于应对通信网络中网络规划、网络配置和资源调度越来越复杂的问题，通信网络中引入了智能模型。
发明内容
本申请实施例提供一种模型配置方法，以解决终端发生移动或小区切换时，目标接入网设备为该终端重新配置模型的完整信息导致的资源浪费以及空口开销较大的问题。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种模型配置方法，该方法可以由第一无线控制装置、芯片或者其它装置执行，或者，该方法可以由第一接入网设备执行，该方法可以包括：向第一小区中的终端发送用于终端处理数据的第一模型的第一部分信息，发送用于指示第一模型的第二部分信息的第一指示信息，第二部分信息为终端位于第二小区时待发送给终端的信息，第一小区与第二小区为不同小区。
本申请实施例中，某一信息，如信息A，用于指示另一信息或特征，如信息B，可以包括：
信息A中包括信息B；
信息A从一个或多个候选信息B中指示信息B，如指示该信息B的索引，其中，该一个或多个候选信息B中的每个候选信息B对应唯一的索引，用于标识该候选信息B；或者，
信息A用于确定信息B，例如，对信息A经过数学运算或滤波等可以得到信息B。
基于第一方面所述的方法，在向第一小区中的终端发送第一模型的第一部分信息时，如果终端移动或切换到不同于第一小区的第二小区，则发送用于指示第一模型的剩余信息(如第二部分信息)的第一指示信息，以使得第二小区对应的设备(如接入网设备等)将第一模型的剩余信息发送给位于第二小区中的该终端。即终端移动或切换到新的小区后，向终端发送第一模型的信息中除第一部分信息之外的剩余信息，实现接续发送，无需将第一模型的全部信息重新发送给终端，减少终端发送移动或小区切换时向该终端重新发送模型的信息带来的空口开销。
一种可能的设计中，发送第一指示信息，包括：向第二无线控制装置发送第一指示信息。该可能的设计可以由第一无线控制装置执行。
基于该可能的设计，可以将第一指示信息直接发送给第二无线控制装置，减少第一指示信息的发送时延，同时，无需引入其他中间设备，简化系统设计。
一种可能的设计中，第一指示信息用于指示第一部分信息在第一模型的信息中的结束位置；或者，第一指示信息用于指示第二部分信息在第一模型的信息中的起始位置；或者，第一指示信息包括第二部分信息，提高第一指示信息的设计灵活性。
一种可能的设计中，在第一小区与第二小区对应的无线控制装置相同的情况下；第一指示信息用于指示终端的标识信息；或者，第一指示信息用于指示终端的标识信息以及第四部分信息在第三部分信息中的起始位置，第三部分信息为从无线控制装置获取到的信息，第四部分信息为第三部分信息中未发送给终端的信息；或者，第一指示信息用于指示终端的标识信息以及第一部分信息在第三部分信息中的结束位置，第三部分信息为从无线控制装置获取到的信息。
基于该可能的设计，可以将终端的标识信息指示给无线控制装置，以便无线控制装置根据终端的标识信息获知第一小区中接收第一模型的信息的终端中的哪个终端发生小区移动或小区切换，向发生移动或小区切换的终端继续发送剩余信息，如第二部分信息，此外，通过指示第四部分信息的起始位置或者第一部分信息的起始位置，实现有效且灵活地指示待发送给终端的第二部分信息。
一种可能的设计中，在第一小区与第二小区对应的无线控制装置相同的情况下，发送第一指示信息包括：向服务于第二小区的第二接入网设备发送第一指示信息；或者，向无线控制装置发送第一指示信息，第一指示信息还包括第二接入网设备的标识信息。

基于该可能的设计，可以使第二接入网设备根据第二部分信息对应的PDCP序列号信息配置第二部分信息对应的数据包的PDCP序列号，按照PDCP序列号顺序向终端发送第二部分信息，以便于终端按照数据包的PDCP序列号对接收到的数据包进行重组得到第一模型的完整信息，提高第一模型的信息的传输准确性，同时，简化系统设计。
一种可能的设计中，所述方法还包括：接收来自终端的用于指示终端成功接收到的信 息和/或者未成功接收到的信息的第二指示信息。
通过该方法，可以根据第二指示信息获知哪些信息被终端成功接收，哪些信息是接收失败的，将接收失败的信息重新发送给终端，提高信息传输的可靠性。
一种可能的设计中，所述方法还包括：向第一无线控制装置发送用于指示终端从第一小区移动或切换到第二小区的第一指示消息，接收来自第一无线控制装置的用于指示第一无线控制装置不再向第一接入网设备发送第一无线控制装置与终端之间交互的信息的第一结束指示。
基于该可能的设计，可以通过与第一无线控制装置之间的信令交互，明确指示终端已发生移动或小区切换，移出第一小区，及时触发第一无线控制装置结束向第一接入网设备发送第一无线控制装置与终端之间交互的信息，避免第一无线控制装置继续向第一接入网设备发送第一无线控制装置与终端之间交互的信息带来的第一无线控制装置和第一接入网设备之间的传输消耗。同时避免第一接入网设备需要把更多的第一无线控制装置与终端之间交互的信息发送给第二接入网设备带来的第一接入网设备和第二接入网设备之间的传输消耗。同时第一无线控制装置可以在获知终端发生小区或者切换到第二小区后，及时向第二接入网设备发送剩余的信息，与由第一无线控制装置向第一接入网设备，再由第一接入网设备向第二接入网设备发送相比，时延更短，简化系统设计。
一种可能的设计中，所述方法还包括：向第二接入网设备发送第二结束指示，第二结束指示用于指示不再向第二接入网设备发送第一无线控制装置与终端之间交互的信息。
基于该可能的设计，可以通过与第二接入网设备之间的信令交互，指示第一无线控制装置与终端之间交互的信息已全部发送给第二接入网设备，不再向第二接入网设备发送第一无线控制装置与终端之间交互的信息，及时触发第二接入网设备停止接收第一指示信息，无需第二接入网设备一直尝试接收第一指示信息，降低第二接入网设备接收第一指示信息的功率消耗。

具体实施方式
为应对通信网络中网络规划、网络配置和资源调度等越来越复杂的问题，实现高效运行的通信网络，通信网络中引入了人工智能(artificial intelligence，AI)技术。该网络中，通过AI技术辅助终端和/或网络侧设备提升网络规划、网络配置和资源调度等的效率，实现无线接入网(radio access network，RAN)智能化。AI技术的目标是让机器具有学习能力，能积累经验，解决人类通过经验可以解决的诸如自然语言理解、图像识别和/或下棋等问题。
机器学习(machine learning，ML)是实现AI的一种重要技术途径。机器学习可以包括监督学习、无监督学习、和强化学习。神经网络(neural network)是机器学习的一 种具体实现形式。机器学习可被认为是一种方法，该方法能够赋予机器(如终端和/网络侧设备)学习能力，以此让机器完成仅靠直接编程无法完成的功能。
下面对本申请实施例涉及的相关技术术语进行解释说明。需要说明的是，这些解释说明是为了让本申请实施例更容易被理解，而不应该视为对本申请实施例所要求的保护范围的限定。
模型：是一种线性或非线性模型，可以提供一种机器学习算法。机器学习算法中，机器可以对训练数据进行训练或者学习，得到AI模型。该AI模型可以用于对输入数据进行预测(如对未来一段时间内的业务数据量预测)，得到预测结果。换句话说，该AI模型可以体现对AI模型的输入数据进行运算的方法，例如表征如何对输入数据进行线性或非线性运算，从而得到AI模型的输出结果。AI模型可以简称为模型、智能模型、ML模型、AI/ML模型、或其它名称，不予限制。利用模型进行预测还可以被称为利用模型进行推理或决策，预测结果还可以称为推理结果或决策结果。当通过神经网络实现机器学习时，上述AI模型还可以称为神经网络模型。
神经网络(neural network)：包括输入层、隐藏层和输出层三种类型的计算层的网络可以称为神经网络。每层拥有一个或多个逻辑判断单元，这种逻辑判断单元称为神经元(neuron)。每个神经元对输入的值进行加权(对应的权值称为权重)得到输出结果，可以认为该输出结果是通过线性或非线性功能来实现的，例如当神经元的输入值超过一些阈值时该神经元才输出。例如，神经网络模型的信息包括：每个计算层包括的神经元和每个神经元的加权系数，以及相邻计算层的神经元之间的连接关系。
神经网络可以包括深度神经网络(deep neural network)。深度神经网络为具备多个隐藏层的神经网络，终端和/网络侧设备可以通过深度神经网络进行深度学习(deep learning)。
通信系统中，如果终端需要利用AI技术实现网络规划、网络配置和/或资源调度等的智能化，则网络侧设备可以将智能模型的信息发送给终端。终端接收到智能模型的信息后，利用该智能模型进行推理或者联邦学习，实现智能的网络功能，如网络规划、网络配置和/或资源调度等。其中智能模型的信息可以包括大量的参数，模型比较大，向终端发送智能模型的信息则需要较高的下行数据速率。
例如，下表一示出了：亚历克斯网络(AlexNet)、视觉几何组16(VGG16)、深度残差网络-152(ResNet-152)、深度残差网络-50(ResNet-50)、谷歌网络(GoogleNet)、起初-V3(Inception-V3)、1.0移动网络-224(1.0MobileNet-224)这几种用于图像识别的神经网络模型的信息。从表一可知，每个神经网络模型包括百万级的参数，在神经网络模型包括的每个参数采用32比特(bit)表示的情况下，神经网络模型的大小(即神经网络模型的总参数)占用几百兆字节(megabyte，MByte)，传输神经网络模型需要的下行数据速率为几百兆比特每秒(Mbit/s，Mbps)、甚至几千Mbps。
表一
Figure PCTCN2020124563-appb-000001
一种可能的实现方式中，如图1a所示，网络侧设备可以将完整的智能模型发送给终端，终端接收到完整的智能模型后，根据智能模型获得预测结果，按照该预测结果进行相应的数据处理。又一种可能的设计中，如图1b所示，网络侧设备将智能模型进行分裂，把智能模型分裂得到的第一部分发送给终端，终端按照该部分智能模型进行处理，把处理结果(也称为中间数据)发送给网络侧设备，网络侧设备基于处理结果执行智能模型的第二部分，即终端侧以及网络侧设备协同利用智能模型进行数据处理，以降低终端的处理负担。
在采用图1a或图1b所示方法向终端发送智能模型的信息的过程中，如果终端发生移动，从一个小区切换到另外一个小区，对于目标接入网设备，无法获知源接入网设备已将智能模型的多少信息发送给终端，这时，目标接入网设备默认源接入网设备发送的智能模型的信息无效，目标接入网设备会重新从头开始向终端发送智能模型的信息，这会导致将重复的信息发送给终端，浪费无线空口资源。
为解决上述问题，本申请实施例提供一种模型配置方法，包括：向第一小区中的终端发送用于终端处理数据的第一模型的第一部分信息，发送用于指示第一模型的第二部分信息的第一指示信息，第二部分信息为终端位于第二小区时待发送给终端的信息。通过该方法，目标接入网设备将第二部分信息发送给终端即可，无需目标接入网设备从头开始向终端发送第一模型的信息，避免因向终端发送重复的第一模型的信息导致的无线空口资源浪费的问题，提高无线空口资源利用率。
本申请实施例各实施例中，第一模型可以用于(或者辅助)终端处理数据，以实现或者辅助实现某种目的或者功能。如第一模型可以用于(或者辅助)终端对数据进行如下处理：推理、模型训练、数理统计、数据分类、联邦学习(federated learning)、或支持向量机(support vector machines，SVM)学习等，以实现或辅助实现以下网络功能中的一种或多种：无线接入技术(radio access technology，RAT)选择、负载均衡、网络节能、覆盖优化、流量控制、调度、信道编码、信道解码、移动性管理、流量预测、调制、和解调等。具体的，第一模型可以为上述AI模型、ML模型、神经网络模型中的一种或者多种模型，还可以为其他辅助终端处理数据的智能模型，不予限制。
本申请实施例各实施例中，第一模型的信息可以包括以下一项或多项：第一模型的标识信息、第一模型的配置信息、第一模型的适用范围、和第一模型的有效时间信息等。下 面对第一模型的标识信息、第一模型的配置信息、第一模型的适用范围、第一模型的有效时间信息进行介绍：
第一模型的标识信息可以唯一标识第一模型。第一模型的标识信息可以是唯一标识第一模型的标识符(identifier，ID)或者名称。第一模型的标识信息还可以用于指示第一模型的功能或目的，例如第一模型的标识信息可以用于指示该第一模型具有如下一种或者多种网络功能：用于无线接入技术(radio access technology，RAT)选择、负载均衡、移动性管理、网络节能、覆盖优化、流控、调度、信道编码、信道解码、调制、解调、和信道状态信息(channel state information，CSI)反馈。其中，CSI反馈可以包括CSI压缩和上报压缩后的CSI。
第一模型的配置信息可以包括第一模型的模型参数(model parameter)、第一模型的模型超参数(model hyper parameter)和/或第一模型的算法。可选地，模型超参数可以归类到模型参数。下面对第一模型的模型参数、第一模型的模型超参数、第一模型的算法进行解释说明：
第一模型的模型参数是模型内部的配置变量。可以用数据估计模型参数的值。第一模型的模型参数有以下特征中的一种或多种：第一模型在进行训练或推理时需要模型参数，可使用的模型的模型参数的值是确定的，模型参数是从数据估计或数据学习获悉的，模型参数通常不由编程者手动设置，以及模型参数通常被保存为第一模型的一部分。例如，模型参数可以是以下一种或多种：神经网络中的权重(即对输入值的加权系数)、激励函数(即神经网络中神经元上的运算函数)、神经网络中的拓扑(即神经网络具有几层，每层具有几个神经元，和/或每层之前神经元之间的关系等)、支持向量机中的支持向量、线性回归中的系数、和逻辑回归中的系数等。
第一模型的模型超参数是模型外部的配置，其值不能从数据估计得到。第一模型的模型超参数有以下特征中的一种或多种：模型超参数常应用于估计模型参数的过程中，模型超参数通常由实践者直接指定，模型超参数通常可以使用启发式方法来设置，和模型超参数通常根据给定的预测建模问题而调整。例如，训练神经网络的学习速率、支持向量机的惩罚参数C和sigma超参数、k邻域中的k可以称为模型超参数。
第一模型的算法是指进行训练或推理的网元(如终端)在执行训练或推理时需要使用的算法的输入参数。其中执行训练或推理时需要使用的算法可以包括但不限于Q-learning算法。对于Q-learning算法而言，核心为一个Q表格，该表格的行和列分别表示状态(state)和行为(action)，Q表格中保存的是在各个状态下采用对应的行为能够获取奖励的期望(称为Q值)。假设Q表格包括m个状态，n个动作，则该Q表格的大小为m*n。
对于利用Q-learning算法进行推理而言，利用Q-learning进行推理的网元(如终端)先确定当前状态，查找当前状态对应的Q值，选择Q值最大的动作，完成一次推理过程，然后进入下一个状态，并采用类似的方法进行推理。也就是说，对于推理而言，Q-learning算法的输入参数是Q表格中的初始内容。
对于利用Q-learning算法进行训练而言，利用Q-learning进行训练的网元(如终端)通过多次探索和更新Q表格的Q值来计算最佳的Q值。网元可以使用一定的算法来更新Q表格的Q值，例如，网元处于S0状态时，选择行为A0，之后进入S1状态，更新S0状态和行为A0对应的Q值。例如，可以采用如下公式更新S0状态和行为A0对应的Q值： Q(S0,A0)_新＝Q(S0,A0)_旧+a*(Q(S0,A0)_目标-Q(S0,A0)_旧)。其中，Q(S0,A0)_新为S0状态和行为A0对应的更新之后的Q值，Q(S0,A0)_旧为S0状态和行为A0对应的更新之前的Q值。Q(S0,A0)_目标＝R(S1)+y*max{Q(S1,b)}，R(S1)为网元在S0状态采用行为A0时进入S1所能获得的奖励，y为衰减值，max{Q(S1,b)}为S1状态下所有可能的行为对应的Q值中的最大Q值，a是学习速率。也就是说，Q-learning算法的输入参数是Q表格中的初始内容，以及R(.)、y、a的取值，R(.)为网元所能获得的奖励。
本申请实施例中，第一模型的适用范围用于指示或确定什么范围内的终端可以使用该第一模型。第一模型的使用范围可以包括公共陆地移动网络(public land mobile network，PLMN)列表信息、和/或小区列表信息等，比如包括物理小区标识(physical cell identifier，PCI)或小区组标识(cell group identifier，CGI)等，只有当终端驻留或连接的小区属于第一模型的适用范围，该终端才可以使用第一模型。
本申请实施例中，第一模型的有效时间信息用于指示或确定第一模型的信息的有效时长，即第一模型的信息在多长时间内有效。超过这个时间第一模型的信息是失效的、不可用的。

在一种网络结构中，图2中的接入网设备可以包括集中式单元(centralized unit，CU)和分布式单元(distributed Unit，DU)。例如，对接入网设备的功能进行拆分，将接入网设备的部分功能部署在一个CU，将剩余功能部署在DU，多个DU共用一个CU，可以节省成本、易于网络扩展。如图3b所示，CU和DU的切分可以按照协议栈切分，其中一种可能的方式是将无线资源控制(radio resource control，RRC)层，服务数据适应协议(service data adaptation protocol，SDAP)层以及包数据汇聚协议(packet data convergence protocol，PDCP)层部署在CU，无线链路控制(radio link control，RLC)层、介质访问控制(media access control，MAC)层以及物理(physical，PHY)层部署在DU。CU和DU之间通过F1接口连接。CU可以代表接入网设备通过NG接口和核心网连接，CU还可以代表接入 网设备通过Xn接口和其他接入网设备连接，CU还可以代表接入网设备通过X2口和其他接入网设备连接执行双连接操作。

步骤501、第一无线控制装置向第一小区中的终端发送第一模型的第一部分信息。
其中，第一小区可以为图2中任一小区，终端可以为第一小区中的任一终端。该终端可以处于无线资源控制_连接态(RRC_connected)或者无线资源控制_非激活态(RRC_inactive)。第一无线控制装置可以为与第一小区对应的无线控制装置，能够向第一小区中的终端配置智能模型等。第一无线控制装置可以独立部署在第一接入网设备之外，也可以部署在第一接入网设备中，第一接入网设备为服务于第一小区的接入网设备。

本申请实施例中，在第一无线控制装置向第一小区中的终端发送第一模型的信息之前，第一无线控制装置还可以与第一小区中的终端进行信息交互(比如信令交互)，确定第一小区中的终端需要第一模型。例如，终端向第一无线控制装置发送初始化消息，该初始化消息用于指示终端需要使用第一模型处理数据，第一无线控制装置接收到初始化消息，确定终端需要使用第一模型处理数据；或者，第一无线控制装置向终端发送用于请求终端的能力的请求消息，终端接收该请求消息，向第一无线控制装置发送终端的能力信息，在终端的能力信息指示终端支持使用第一模型处理数据的情况下，第一无线控制装置确定终端需要使用第一模型处理数据。
其中，第一模型可以称为智能模型，第一模型可以包括但不限于AI模型、ML模型、神经网络模型中的一种或者多种模型，还可以包括其他辅助终端处理数据的智能模型等。具体的，第一模型的相关描述如上述所述，不予赘述。
其中，第一模型的第一部分信息可以包括第一模型的信息中已发送给终端的信息。本申请实施例中，第一模型的信息不限于包括以下一项或多项：第一模型的标识信息、第一模型的配置信息中的全部信息或者部分信息、第一模型的适用范围、和第一模型的有效时间信息等。此外，第一模型的信息还可以包括第一无线控制装置向终端发送第一模型的信息之前，第一无线控制装置与第一小区中的终端进行信息交互的一些信息(如上述初始化消息或者请求消息等)，也可以包括其他一些与第一模型发送相关的信息等，不予限制。其中第一模型的标识信息、第一模型的配置信息、第一模型的适用范围、第一模型的有效时间信息相关描述如上所述，不予赘述。
示例性的，第一无线控制装置可以采用下述方式(1.1)或者方式(1.2)向第一小区中的终端发送第一模型的第一部分信息：
方式(1.1)、广播方式+单播方式。
例如，第一无线控制装置生成广播信息，向第一小区广播信息，该广播信息中包括一个或者多个模型的信息以及这些一个或者多个模型对应的标识信息，该一个或者多个模型可以包括第一模型；以及第一无线控制装置生成单播信息，向第一小区中的终端发送单播信息，单播信息包括第一模型的标识信息，其中单播信息还可以称为终端的专用消息。
相应的，第一小区中的终端接收广播信息以及单播信息，解析得到单播信息中包括的第一模型的标识信息，根据第一模型的标识信息从广播消息中获取第一模型的第一部分信息。
方式(1.1)中第一无线控制装置可以通过第一接入网设备发送广播信息以及单播信息，如第一无线控制装置可以将广播信息、单播信息发送给第一接入网设备，第一接入网设备接收广播信息以及单播信息，并发送广播信息、单播信息。
可替换的，方式(1.1)中，第一无线控制装置可以将第一模型的第一部分信息发送给第一接入网设备，由第一接入网设备生成上述广播信息、单播信息，并将生成的广播信息和单播信息发送给终端。
本申请各实施例中，第一接入网设备发送广播信息和单播信息可以包括：第一接入网设备通过数据无线承载(data radio bearer，DRB)或者信令无线承载(signalling radio bearer，SRB)发送广播信息和单播信息。其中，第一接入网设备通过DRB或者SRB发送广播消息和单播消息还可以描述为第一接入网设备将广播信息和单播信息承载在DRB或者SRB中发送出去。例如，以第一无线控制装置为图3c中的RIC为例，RIC可以生成上述广播信息、单播信息，将生成的广播信息、单播信息通过RRC、PDCP-C处理后，递交给DU，由DU将广播信息、单播信息承载在DRB中发送出去。又例如，当第一无线控制装置位于第一接入网设备的DU时，DU可以把第一模型的信息发送给第一接入网设备的CU，再由CU把第一模型的信息承载在SRB中发送给终端。
方式(1.2)、单播方式。
例如，第一无线控制装置生成单播信息，向第一小区中的终端发送单播信息，该单播信息包括第一模型的第一部分信息。相应的，第一小区中的终端接收单播信息，解析得到单播信息中包括的第一模型的第一部分信息。
需要说明的是，虽然方式(1.1)和方式(1.2)中单播信息的名称相同，但是其实不同方式中单播信息包括的内容是不同的。
方式(1.2)中第一无线控制装置可以通过第一接入网设备发送单播信息，如第一无线控制装置可以将单播信息发送给第一无线网设备，第一无线控制装置接收单播信息，并发送单播信息。可替换的，方式(1.2)中，第一无线控制装置还可以将第一模型的第一部分信息发送给第一接入网设备，由第一接入网设备生成上述单播信息，并将生成的单播信息发送出去。
方式(1.2)中，第一接入网设备发送单播信息可以包括：第一接入网设备通过DRB或者SRB发送单播信息。例如，以第一无线控制装置为图3c中的RIC为例，RIC可以生成上述单播信息，将生成的单播信息通过RRC、PDCP-C处理后，递交给DU，由DU将单播信息承载在DRB中发送给终端。
可选的，方式(1.2)中，第一无线控制装置除了把第一模型的信息发送给终端之外， 还可以为终端分配一个终端的标识信息，并通过单播信息发送给终端。如方式(1.2)中的单播信息还包括终端的标识消息以及其他信息等，该单播信息可以称为终端的专用消息。需要说明的是，本申请实施例所述的终端的标识信息还可以是在第一无线控制装置与终端之间进行信息交互过程中由第一无线控制装置发送给终端的，不予限制。
本申请实施例中，终端的标识信息可以用于标识终端，终端的标识信息可以为终端的因特网协议(internet protocol，IP)地址、终端的媒体接入控制(media access control，MAC)地址、终端的国际移动用户识别码(international mobile subscriber identity，IMSI)、终端的小区无线网络临时标识(cell radio network temporary identity，C_RNTI)或者终端的非激活态无线网络临时标识(inactive radio network temporary identity，I_RNTI)等。
由于第一模型的第一部分信息比较大，第一无线控制装置或者第一接入网设备向终端发送该第一模型的信息时，可以将第一模型的信息先处理成如下述(2.1)或者(2.2)所示形式后，再通过上述方式(1.1)或者方式(1.2)发送给终端。
(2.1)、数据包形式。
例如，第一无线控制装置或者第一接入网设备可以将第一模型的信息划分为多份信息，将多份信息分别打包成多个数据包，例如该数据包可以为PDCP数据包，一个数据包对应一份信息。不同数据包携带的信息的大小可以相同或者不同。对于一个数据包，该数据包还可以携带第三指示信息，第三指示信息用于指示该数据包携带的那份信息在第一模型的信息中的位置。
进一步的，第一无线控制装置或者第一接入网设备将生成的数据包通过上述(1.1)或者方式(1.2)发送出去。
其中，第三指示信息可以为数据包的序列号、或者数据包携带的那份信息的起始位置距离第一模型的信息的起始位置之间的偏移值、或者数据包携带的那份信息的起始位置距离第一模型的信息的终点位置之间的偏移值等等。
(2.2)、消息形式。
例如，第一无线控制装置或者第一接入网设备可以将第一模型的信息划分为一份或多份信息，将该一份或多份信息依次包括于一个消息中，该消息可以称为长消息；后续把该长消息称为第一消息。第一消息中可能携带一个序列号。
如果第一消息的长度小于第一接入网设备与终端之间的空口支持的能传输的最大信息长度，则第一无线控制装置或者第一接入网设备向终端发送第一消息。第一消息可以携带第四指示信息，第四指示信息用于指示第一消息为长消息。终端收到第四指示信息时，终端能知道当前接收的消息就是整个第一消息；
如果第一接入网设备与终端之间的空口支持的能传输的最大信息长度小于第一消息的长度，则第一无线控制装置或者第一接入网设备将第一消息分割为多个短消息，通过上述(1.1)或者方式(1.2)向终端发送多个短消息，每次发送一个或者多个以上短消息。
其中，每个短消息中包括第一模型的部分信息，每个短消息还包括第五指示信息。第五指示信息用于指示该短消息在第一消息中的位置。如第五指示信息可以包括短消息对应的编号、序列号、或者距离第一消息的起始位置的偏移值等。第五指示信息还可以用于指示该短消息为分割第一消息得到的消息(或者描述为该短消息携带的信息是第一消息携带的信息的部分信息)。可选地，第五指示信息还可以指示该短消息是否是第一消息分割得 到的最后一个短消息。终端收到第五指示信息时，终端能知道当前接收的消息就是第一消息对应的一个短消息，且知道后续是否还有该第一消息的其他短消息。
可选地，第四指示信息和第五指示信息可能是对应同一个指示信息，只是该指示信息在不同的情况下对应不同的取值。
进一步的，第一无线控制装置还可以接收终端返回的第二指示信息，第二指示信息用于指示终端成功接收到的信息和/或者未成功接收到的信息。该方法可用于传输中出现传输错误或丢包的情况。第一无线控制装置可以根据终端反馈的哪些信息没有正确接收来进行重传，继续向终端重传这些传输错误的信息或被丢弃的信息。需要说明的是，对于上述(2.1)而言，这里的信息是指数据包。对于上述(2.1)而言，这里的信息是指长消息或短消息。
步骤502：终端接收第一模型的第一部分信息。
示例性的，终端可以通过SRB或者DRB接收第一模型的第一部分信息。
进一步的，终端保存接收到的第一模型的第一部分信息。如终端可以在自己的一个变量中记录该第一模型的第一部分信息，并且还可能在该变量中记录第六指示信息，该第六指示信息可以用于指示第一模型的第一部分信息是从第一小区接收到的。第六指示信息可以为第一小区的小区标识。其中，第一小区的小区标识可以用于唯一标识第一小区，第一小区的小区标识可以为第一小区的第一小区的PCI或者全球小区识别码(cell global identification，CGI)等。具体的，至于终端如何保存该变量，本申请实施例并不限定。
其中，在终端接收第一模型的信息的过程(如终端接收第一部分信息的结束时刻)，终端可能发生移动或者小区切换中，如终端可以在无线资源控制_连接态(RRC_connected)下发生移动或者终端在RRC_connected下发生RRC重建，从第一小区移动或切换到第二小区；或者，终端在无线资源控制_非激活态(RRC_inactive)下发生移动，从第一小区移动或切换到第二小区，第二小区与第一小区不同。例如，以终端为图2中的终端1为例，终端1可以从小区1.1移动或切换到小区2.1。
步骤503：第一无线控制装置向第二无线控制装置发送第一指示信息。
其中，第二无线控制装置可以为与第二小区对应的无线控制装置，能够为第二小区中的终端提供第一模型的信息，第二小区与第一小区不同，第二小区可以是为终端提供服务的小区。图5所示方法中，第二无线控制装置与第一无线控制装置是不同的两个无线控制装置，如部署位置不同等，第二无线控制装置可以部署在第二接入网设备之外，也可以部署在第二接入网设备中，不予限制。第二接入网设备为服务于第二小区的接入网设备。
例如，如图2所示，假设终端1从小区1.1移动或切换到小区2.1，第一小区为小区1.1，第二小区为2.1，第二无线控制装置为无线控制装置2。
其中，第一指示信息可以用于指示第一模型的第二部分信息，第一指示信息可以替换描述为第一模型的上下文信息。第一模型的第二部分信息可以为终端位于第二小区时待发送给终端的信息，第一模型的第二部分信息可以称为第一模型的信息中未发送给终端的信息或者第一模型的信息中的剩余信息。第一指示信息包括如下第一种实现方式～第三种实现方式中的任一种：
第一种实现方式，第一指示信息用于指示已发送给终端的第一部分信息在第一模型的信息中的位置信息，比如指示第一部分信息在第一模型的信息(可以包括在发送第一模型的信息之前第一无线控制装置与终端交互的信息)中的结束位置。可选的，第一指示信息 还包括第一模型的标识信息。
在以上述(2.1)所示的数据包的形式向终端发送第一模型的信息的情况下，第一指示信息可以包括第一部分信息对应的最后一个数据包的序列号，或者最后一个数据包的起始位置距离第一模型的信息的起始位置之间的偏移值，或者第一部分信息对应的所有数据包的序列号，或者第一部分信息中每个数据包的起始位置距离第一模型的信息的起始位置之间的偏移值，或者第一无线控制装置向终端发送了且未被终端正确接收的所有数据包的序列号及第一部分信息对应的最后一个数据包的序列号。其中，针对数据包的不同发送方式，第一指示信息包括的具体内容是不同的。
例如，如果只有当一个数据包发送成功之后才向终端发送下一个数据包，则第一指示信息可以包括第一部分信息对应的最后一个数据包的序列号，或者最后一个数据包的起始位置距离第一模型的信息的起始位置之间的偏移值。如果在一个数据包还没有发送成功之前就可以向终端发送下一个数据包，则第一指示信息可以包括第一部分信息对应的数据包的序列号(比如第一部分信息对应的所有数据包的序列号，或者第一部分信息对应的最后一个数据包的序列号，或者第一无线控制装置向终端发送了且未被终端正确接收的所有数据包的序列号及第一部分信息对应的最后一个数据包的序列号)，或者，每个数据包的起始位置距离第一模型的信息的起始位置之间的偏移值。
在以上述(2.2)所示消息方式向终端发送第一模型的信息的情况下，第一指示信息可以包括第一部分信息对应的最后一个消息的序列号，第一部分信息对应的所有消息的序列号，或者最后一个消息的起始位置距离第一模型的信息的起始位置之间的偏移值，或者第一部分信息中每个消息的起始位置距离第一模型的信息的起始位置之间的偏移值，或者第一无线控制装置向终端发送了且未被终端正确接收的所有消息的序列号及第一部分信息对应的最后一个消息的序列号。其中，针对消息的不同发送方式，第一指示信息包括的具体内容是不同的。
比如：如果只有当一个消息发送成功之后才向终端发送下一个消息，则第一指示信息可以包括第一部分信息对应的最后一个消息的序列号或者最后一个消息的起始位置距离第一模型的信息的起始位置之间的偏移值。如果在一个消息还没有发送成功之前就可以向终端发送下一个消息，则第一指示信息可以包括第一部分信息对应的消息的序列号(比如第一部分信息对应的所有消息的序列号，或者第一部分信息对应的最后一个消息的序列号，或者第一无线控制装置向终端发送了且未被终端正确接收的所有消息的序列号及第一部分信息对应的最后一个消息的序列号)，或者，每个消息的起始位置距离第一模型的信息的起始位置之间的偏移值。
应理解，如果在发送第一模型的信息之前存在第一无线控制装置与终端交互的信息，则上述偏移值可以指距离第一无线控制装置与终端交互的信息的起始位置的偏移值，如果在发送第一模型的信息之前不存在第一无线控制装置与终端交互的信息，则上述偏移值可以指距离第一模型的信息的起始位置的偏移值。
第二种实现方式，第一指示信息用于指示待发送给终端的第二部分信息在第一模型的信息(可以包括在发送第一模型的信息之前第一无线控制装置与终端交互的信息)中的起始位置。可选的，第一指示信息还可以包括第一模型的标识信息。
本申请实施例中，第二部分信息还可以描述为第一模型的信息中除已发送给终端的第 一部分信息之外的剩余信息或者第一模型的剩余信息或者第一模型的信息中未发送给终端的信息或者第一模型的信息中未向终端发送的信息。
类似的，在采用上述(2.1)或上述(2.2)的形式发送第一部分信息的情况下，可以采用第一种实现方式中发送第一模型的信息类似的方式来表示用于指示第二部分信息的起始位置的第一指示信息，具体如下所示：
在以上述(2.1)所示的数据包的形式发送第一模型的信息的情况下，第一指示信息包括第二部分信息的第一个数据包的序列号，或者第二部分信息的第一个数据包的起始位置距离第一模型的信息的起始位置之间的偏移值，或者第二部分信息对应的所有数据包的序列号，或者第二部分信息中每个数据包的起始位置距离第一模型的信息的起始位置之间的偏移值，或者第一无线控制装置向终端发送了且未被终端正确接收的所有数据包的序列号及第一无线控制装置未向终端发送的第一个数据包对应的序列号。
其中，针对数据的下述两种不同发送方式：一、只有当一个数据发送成功之后才向终端发送下一个数据；二、在一个数据还没有发送成功之前就可以向终端发送下一个数据。第一指示信息包括的具体内容是不同的。具体的，该实现方式可参照第一种实现方式中所述，不予赘述。
在以上述(2.2)所示消息的形式发送第一模型的信息的情况下，第一指示信息包括第二部分信息对应的第一个消息的序列号，第二部分信息对应的所有消息的序列号，或者第二部分信息对应的第一个消息的起始位置距离第一模型的信息的起始位置之间的偏移值，或者第二部分信息中每个消息的起始位置距离第一模型的信息的起始位置之间的偏移值，或者第一无线控制装置向终端发送了且未被终端正确接收的所有消息的序列号及第一无线控制装置未向终端发送的第一个消息对应的序列号。
其中，针对消息的下述两种不同发送方式：一、只有当一个消息发送成功之后才向终端发送下一个消息；二、在一个消息还没有发送成功之前就可以向终端发送下一个消息。第一指示信息包括的具体内容是不同的。具体的，该实现方式可参照第一种实现方式中所述，不予赘述。
第三种实现方式，第一指示信息可以包括第二部分信息。
可选的，第一指示信息还可以包括第一模型的标识信息。
其中，第二部分信息的相关描述如上所述，不予赘述。
需要说明的是，在第一指示信息用于指示第一部分信息在第一模型的信息中的结束位置；或者，第一指示信息用于指示第二部分信息在第一模型的信息中的起始位置的情况下，第二无线控制装置可以本地存储有第一模型的信息或者第二无线控制装置可以从其他设备获取到第一模型的信息，第二无线控制装置存储的或获取的第一模型的信息的大小以及内容与第一无线控制装置本地存储的第一模型的信息的大小以及内容是完全相同的。进一步的，在第二部分信息包括在发送第一模型的信息之前第一无线控制装置与终端交互的信息时，第一无线控制装置存储的需要和终端交互的信息和第二无线控制装置存储的需要和终端交互的信息的大小以及内容是完全相同的。
示例性的，在第一无线控制装置确定终端从第一小区移动或切换到第二小区时，触发第一无线控制装置向第二无线控制装置发送第一指示信息。进一步的，第一无线控制装置停止向第一小区中的终端发送第一模型的信息。
本申请实施例中，第一无线控制装置向第二无线控制装置发送第一指示信息可以包括：第一无线控制装置直接向第二无线控制装置发送第一指示信息，或者，第一无线控制装置向第一接入网设备发送第一指示信息，第一接入网设备接收第一指示信息，向第二接入网设备发送第一指示信息，由第二接入网设备将第一指示信息发送给第二无线控制装置。
比如，在终端处于连接态且从第一小区移动或切换到第二小区的情况下，第一接入网设备向第二接入网设备发送切换请求，切换请求中携带第一指示信息，即在切换流程中，由第一接入网设备将第一指示信息发送给第二接入网设备。或者，在终端处于非激活态且从第一小区移动或切换到第二小区的情况下，第一接入网设备接收来自第二接入网设备的请求UE上下文的请求消息，第一接入网设备向第二接入网设备发送携带UE上下文的响应消息，该响应消息中还携带有第一指示信息，即在终端的RRC恢复连接流程中，由第一接入网设备将第一指示信息发送给第二接入网设备，降低信令开销。
本申请实施例中，第一无线控制装置确定终端从第一小区移动或切换到第二小区可以包括：对于第一无线控制装置独立部署在第一接入网设备之外的场景，第一接入网设备收到第二接入网设备发送的切换请求响应消息或者获取UE上下文请求消息之后，确定终端移动或切换到第二小区；第一无线控制装置接收来自第一接入网设备的通知消息，该通知消息用于通知第一无线控制装置终端从第一小区移动或切换到第二小区。
步骤504：第二无线控制装置从第一无线控制装置接收第一指示信息，根据第一指示信息向第二小区中的终端发送第二部分信息。
其中，步骤504中所述的第二小区中的终端是指从第一小区移动到或切换到第二小区的上述终端，该终端已接收了第一模型的第一部分信息。
示例性的，第二无线控制装置可以先确定第一无线控制装置向终端发送的第一模型或第一模型的信息，进而根据第一指示信息获知第一无线控制装置已经向终端发送了第一模型的信息中的哪些内容，将第一模型的信息中的除第一无线控制装置已发送给终端的信息之外的剩余内容继续发送给位于第二小区中的终端。
其中，第二无线控制装置可以根据下述几种方式确定第一无线控制装置向终端发送的第一模型或第一模型的信息：
方式1、第二无线控制装置和第一无线控制装置采用的第一模型是相同的或采用的第一模型的信息是相同的，且第一模型的标识信息也是相同的，这样第二无线控制装置根据第一指示信息包括的第一模型的标识信息就知道终端之前已接收并保存(或者已发送给终端的)的第一模型或第一模型的信息是哪一个。
方式2、第二无线控制装置和第一无线控制装置可能采用的第一模型或第一模型的信息是不同的，但两个第一无线控制装置之间事先交互了各自的第一模型的信息及第一模型的标识信息，这样第二无线控制装置根据第一指示信息中第一模型的标识信息就知道第一无线控制装置给终端配置的是哪一个第一模型的信息。
方式3、第二无线控制装置和第一无线控制装置只支持一个第一模型或第一模型的信息，且第二无线控制装置和第一无线控制装置支持的第一模型或第一模型的信息是相同的，这样第二无线控制装置接收到第一指示信息，即可以知道第一无线控制装置给终端配置了第一模型的信息。
方式4、第二无线控制装置和第一无线控制装置下对应的每个小区只支持一个第一模 型或第一模型的信息，且第二无线控制装置和第一无线控制装置下对应的每个小区支持的第一模型或一个第一模型的信息是相同的，这样第二无线控制装置根据第一小区的小区标识就知道第一无线控制装置给终端配置了第一小区支持的第一模型的信息。
进一步的，根据第一指示信息将第一模型的信息中的除第一无线控制装置已发送给终端的信息之外的剩余内容继续发送给位于第二小区中的终端。例如，第二无线控制装置根据第一指示信息中的第一部分信息对应到最后一个数据包/消息的序列号，获知哪些序列号之前的数据包/消息已发送给了终端，第二无线控制装置继续向终端发送剩下的第一模型的第二部分信息，如继续发送第一部分信息对应的最后一个数据包的序列号之后的下一个序列号及后续序列号对应的数据包。
又例如，第二无线控制装置根据第一指示信息中的第二部分信息对应到第一个数据包的序列号，获知要开始发送哪些数据包，第二无线控制装置继续向终端发送第一个数据包以及第一个数据包的序列号之后的后续序列号对应的数据包。
再例如，在第一部分信息包括发送第一模型的信息之前第一无线控制装置与终端交互的信息中的部分信息的情况下，第二无线控制装置根据第一指示信息获知第一无线控制装置与终端交互了哪些信息，已进行了哪些交互过程，则第二无线控制装置可以不进行这些交互过程，执行剩下的交互过程，并在第一无线控制装置与终端交互的信息传输完成后，再向终端发送第一模型的信息，如第一模型的配置信息等。
需要说明的是，第二接入控制装置发送第二部分信息与第一接入控制装置发送第一模型的信息的方式相同，可以采用步骤501中所述的方式(1.1)或者方式(1.2)发送第二部分信息，其中第二部分信息与第一部分信息的发送形式相同，第二部分信息也可以采用步骤501中(2.1)所示的数据包形式或者(2.2)所述的消息形式发送出去。
进一步的，第二无线控制装置还可以向终端发送第七指示信息，第七指示信息可以用于指示终端继续采用已经保存的第一模型，以便终端根据第七指示将自己之前保存的第一部分信息与第二部分信息合并起来。
一种可能的设计中，第七指示信息可以包括第一模型的标识信息。又一种可能的设计中，在终端只接收了一个第一模型的信息的情况下，第七指示信息包括布尔变量：假(false)或者真(true)，该布尔变量指示终端是否采用已经接收的第一模型的信息(即第一部分信息)，比如该布尔变量取值为真时，指示终端采用已经接收的第一模型的信息，否则，该布尔变量取值为假时，意味着第一模型发生变化或者第一模型的信息发生变化，第二无线控制装置给终端下发的第二部分信息为新的模型(更新后的第一模型)的信息，或第一模型的更新信息(如将第一模型中的一些信息更新后得到的信息)，终端不能将第二部分信息与第一部分信息合并起来作为第一模型的完整信息。
可选的，第二无线控制装置可以无需向终端发送第七指示信息，而是第二无线控制装置直接发送第二部分信息，当终端设备收到第二部分信息时，就默认继续采用已经保存的第一模型。例如，终端可以根据数据包或消息的序列号(比如不是从0开始)获知是继续采用已经保存的第一模型。
步骤505、终端接收第二部分信息。
进一步的，终端从第二无线控制装置接收第二部分信息后，和之前从第一无线控制装置接收的第一部分信息合并获得最终的完整的第一模型的信息。
例如，终端接收到用于指示终端继续采用已经保存的第一模型的第七指示信息，根据第七指示信息，从本次获取之前从第一无线控制装置接收的第一部分信息，将第一部分信息和第二部分信息合并获得第一模型的完整信息。
又例如，第二无线控制装置没有向终端发送第七指示信息，终端接收到第二部分信息后，默认将第二部分信息后和之前从第一无线控制装置接收的第一部分信息合并获得最终的完整的第一模型的信息。
基于图5所示方法，第一无线控制装置向第一小区中的终端发送第一模型的第一部分信息时，如果终端移动或切换到不同于第一小区的第二小区，则第一无线控制装置向第二无线控制装置发送用于指示第一模型的剩余信息(如第二部分信息)的第一指示信息，以使得第二无线控制装置将第一模型的剩余信息发送给位于第二小区中的该终端，实现接续发送，无需终端移动或切换到新的小区后，将第一模型的全部信息重新发送给终端带来的空口开销。
上述图5所示方法以第一无线控制装置向第二无线控制装置发送第一指示信息为例进行了说明，可替换的，还可以由终端向第二无线控制装置发送第一指示信息，将第二部分信息的位置信息指示给第二无线控制装置。具体的，该过程可参照下述图6所示。

上述图5或图6所示方法以第一无线控制装置或者终端向第二无线控制装置发送第一指示信息为例进行说明，可替换的，还可以由第一接入网设备生成第一指示信息，向第二接入网设备发送第一指示信息。具体的，该过程可参照图7或者图8所示。

一种可能的设计中，第一指示信息用于指示终端的标识信息。以便无线控制装置根据第一指示信息获知哪个终端发生移动或小区切换，移动或切换到新的小区。此时，默认第三部分信息均已发送给终端，将第一模型的信息中除第三部分信息之外的剩余信息发送给位于新的小区中的终端。
又一种可能的设计中，第一指示信息用于指示终端的标识信息以及第四部分信息在第三部分信息中的位置(比如向终端发送了且未被终端正确接收的所有数据包或消息的序列号及未向终端发送的第一个数据包或消息对应的序列号，或者第四部分信息在第三部分信息中的起始位置)，第四部分信息为第三部分信息中未发送给终端的信息。
再一种可能的设计中，第一指示信息用于指示终端的标识信息以及第一部分信息在第三部分信息中的位置(比如第一部分信息的所有数据包或消息的序列号，或者第一部分信息在第三部分信息中的结束位置)。如此，将发送给第一接入网设备但第一接入网设备未发送给终端的那部分信息指示给无线控制装置，以便无线控制装置将第一接入网设备未发送给终端的第四部分信息继续发送给位于第二小区中的终端。
