图1、图2分别是适用于本申请实施例的无线通信系统100、200的一示意图。
本适用于申请实施例的无线通信系统可以包括至少两个网络设备，该至少两个网络设备可以是架设于地面的网络设备，如图1所示的无线通信系统100中的网络设备130、140。该至少两个网络设备也可以是卫星，如图2所示的无线通信系统200中的网络设备230、240。或者，该至少两个网络设备中包括一个架设于地面的网络设备和一个卫星，本申请对此不作限定。本适用于申请实施例的无线通信系统还可以包括至少两个终端设备，如图1所示的无线通信系统100中的终端设备110、120，或者，如图2所示无线通信系统200中的终端设备210、220。该至少两个终端设备连接于该至少两个网络设备中的同一网络设备下的小区，该网络设备可以通过本申请实施例提供的方法将该至少两个终端设备切换至该至少两个网络设备中的另一个网络设备的小区。

应理解，本申请对于终端设备的具体形式不作限定。
本申请实施例中的网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，无线保真(Wireless Fidelity，WIFI)系统中的接入点(Access Point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G(如NR)系统中的gNB或传输点(TRP或TP)，或者，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。

在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，简称AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(medium access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。

本申请提出源网络设备(即，第一网络设备的一例)在一次切换请求中请求切换多个终端设备至目标网络设备(即，第二网络设备的一例)的小区以及通过同一下行控制信息调度多个终端设备的切换小区的信息，能够节省信令开销，提高资源的利用率。
图3是本申请实施例提供的切换小区的方法的一示意性流程图。
需要说明的是，为了清楚地介绍本申请的方案，图3所示的实施例中以两个终端设备即终端设备A、终端设备B作为示例进行说明，本申请的方案可以用于同时请求多个终端 设备的小区切换。
S310，网络设备#1(即，第一网络设备的一例)确定将终端设备A和终端设备B切换至网络设备#2(即，第二网络设备的一例)的小区。
一种实施方式中，网络设备#1可以根据终端设备的位置和/或终端设备的数据承载的特征，比如数量和参数，将终端设备分组后，网络设备#1根据终端设备组中终端设备的测量报告确定将该终端设备组中的终端设备切换至网络设备#2的小区。终端设备的位置可以是终端设备的绝对地理位置(例如，地理坐标)，或是该终端设备相对于网络设备#1或网络设备#2的相对地理位置，本申请对此不作限定。其中，承载是终端设备与网络设备连接时用来传输数据的通道，其容量，时延和误码率等参数由网络设备配置。如果终端设备A与终端设备B的承载数量相同，两者的承载参数又一一相近或相同，那么可以认为这两个终端设备具有相同的承载特征，其中承载参数相近是指相同类型的承载参数的值小于预设值。例如，终端设备A有两个承载M和N，M的容量，时延和误码率分别是X1，Y1，Z1；N的容量，时延和误码率分别是X2，Y2，Z2。终端设备B有两个承载K和L，K的容量，时延和误码率分别与M的容量，时延和误码率相近或相同，L的容量，时延和误码率分别与N的容量，时延和误码率相近或相同。那么网络设备#1可以认为终端设备A与终端设备B有相近或相同的承载(或承载特征)，将终端设备A和终端设备B分在同一组中。
例如，同一终端设备组中的终端设备的位置相同或相近。网络设备#1根据终端设备A和终端设备B的位置，将终端设备A和终端设备B划分为同一组，例如，终端设备A和终端设备B组成终端设备组#1(即，第一终端设备组的一例)。其中，网络设备#1可以通过终端设备上报位置信息，确定该终端设备的位置。
再例如，同一终端设备组中的终端设备的承载特征相同，例如终端设备A和终端设备B都在进行通话。网络设备#1根据终端设备A和终端设备B的数据承载的特征，将终端设备A和终端设备B划分为终端设备组#1。
再例如，同一终端设备组中的终端设备的位置相同或相近，并且数据承载的特征相同或相近。网络设备#1确定终端设备A和终端设备B的位置相同或相近，并且数据承载的特征相同或相近，因此，将终端设备A和终端设备B划分为终端设备组#1(即，第一终端设备组的一例)。
作为示例非限定，网络设备#1可以根据终端设备组中的一个或多个终端设备向网络设备发送的测量报告，确定将该终端设备组中的终端设备切换至网络设备#2的小区。
例如，网络设备#1根据终端设备组中的部分终端设备(比如一个或若干个)的测量报告，确定切换该终端设备组中终端设备。一个终端设备组中的终端设备的位置相同或相近，当一个终端设备组中的部分终端设备向网络设备#1上报服务小区的质量差需要切换至目标小区时，同一终端设备组中位置相近的终端设备在该服务小区的通信质量差的概率也比较大。因此，可以根据终端设备组中的该部分终端设备的测量报告确定切换该终端设备组中的终端设备。例如，终端设备组#1中终端设备A的测量报告指示服务小区的服务质量差，需要切换至网络设备#2的小区，则网络设备确定将终端设备组#1中的终端设备A和终端设备B切换至网络设备#2的小区，但本申请不限于此。
再例如，网络设备#1根据终端设备组中的所有终端设备的测量报告，确定切换该终 端设备组中终端设备。比如，网络设备#1可以在该终端设备组中上报小区服务质量差的终端设备比例大于一个阈值时，确定切换该终端设备组中的终端设备的服务小区。或者，网络设备#1也可以在该终端设备组中的终端设备均报告服务小区的服务质量差的情况下，网络设备#1确定切换该终端设备组中的终端设备的服务小区，但本申请不限于此。
另一种实施方式中，网络设备#1可以根据终端设备A和终端设备B的测量报告，确定将终端设备A和终端设备B切换至网络设备#2的小区。
也就是说，网络设备#1可以不将终端设备进行分组，在接收到多个终端设备的测量报告后，确定一起切换的多个终端设备。
例如，网络设备#1接收到多个终端设备的测量报告，其中，终端设备A和终端设备B的位置相同或相近，并且终端设备A的测量报告和终端设备B的测量报告中均指示网络设备#2的小区的质量较好，则网络设备#1确定将终端设备A和终端设备B切换至网络设备#2的小区，但本申请不限于此。
可选地，终端设备的测量报告可以包括终端设备的位置信息。

作为示例非限定，网络设备#1可以根据终端设备的位置和/或终端设备的承载特征将终端设备分组。
另一种实施方式中，网络设备#1在确定采用公共调度信息(例如，组公共调度信息，比如，信息B)或者说同一信息调度终端设备A和终端设备B的用于切换小区的信息的情况下，在发送该公共调度信息之前，向终端设备A和终端设备B分别发送该信息A1和该信息A2。终端设备A接收信息A1，确定该标识#3。终端设备B接收信息A2，确定该标识#3。也就是说，网络设备#1不提前对终端设备进行分组，在确定需要采用公共调度信息调度终端设备A和终端设备B的用于切换小区的信息后，通知终端设备A和终端设备B用于接收用于切换小区的信息的该标识#3。例如，在与图3实施例结合实施的情况下，网络设备#1可以在S320后向终端设备A和终端设备B分别发送该信息A1和该信息A2，但本申请不限于此。

作为示例非限定，信息B中包括标识#3，终端设备A和终端设备B根据标识#3确定 信息B可以用于确定用于切换小区的信息。
一种实施方式中，标识#3为信息B中的信息比特的扰码序列。
例如，网络设备#1可以采用标识#3对信息B中的信息比特加扰，终端设备可以根据标识#3对收到的信息B进行解扰，从而获得信息B中的信息比特。
再例如，网络设备#1可以采用标识#3对信息B中信息比特中包括的CRC校验位进行加扰，终端设备根据标识#3对该CRC校验位进行解扰，从而获得信息B中的信息比特。
根据上述方案，标识#3作为信息B中包括的扰码序列，能够提高信息的安全性，使的不知道标识#3的设备无法解扰信息B，或者，避免标识#3标识的终端设备以外的设备解扰信息B而造成不必要的功率开销。
另一种实施方式中，标识#3承载在信息B的一个比特域中。
终端设备A和终端设备B接收到该信息B，且信息B中的该比特域承载了标识#3，则终端设备A和终端设备B确定该信息B可以用于确定用于切换小区的信息。若信息B中信息B中的该比特域承载的不是标识#3，则终端设备A和终端设备B确定该信息B不用于终端设备A和终端设备B确定用于切换小区的信息。
根据资源#1承载的信息不同，可以包括以下两种可能的步骤。
可能一
S450，网络设备#1在资源#1上向终端设备A和终端设备B发送信息C(即，第四信息的一例)。

可选地，该信息C为终端设备A和终端设备B的用于切换小区的信息经过公共密钥 加扰后的信息，也就是说，信息C为终端设备组#1的用于切换小区的信息经过组密钥加扰后的信息。该公共密钥为网络设备#1为终端设备A和终端设备B分配的密钥，该组密钥为网络设备#1为终端设备A和终端设备B组成的终端设备组#1分配的密钥。
例如，该终端设备A和终端设备B公共的用于切换小区的信息可以通过网络设备#1为终端设备A和终端设备B分配的公共密钥加扰，或者说，该终端设备组#1的用于切换小区的信息可以经过组密钥加扰。终端设备根据该公共密钥或组密钥对信息C进行解密或解扰后得到用于切换小区的信息。
能够避免其他终端设备组中的终端设备获取终端设备A和终端设备B的用于切换小区的信息，提高信息的安全性。

作为示例非限定，信息C可以承载在RRC重配置(RRC reconfiguration)消息中。
另一种实施方式，信息C包括两个专用信息，该两个专用信息分别对应终端设备A和终端设备B。终端设备A的专用信息为终端设备A的用于切换小区的信息，终端设备B的专用信息为终端设备B的用于切换小区的信息。终端设备A的用于切换小区的信息和终端设备B的用于切换小区的信息以码分复用、频分复用或时分复用中的一种或多种形式承载在资源#1上。
例如，终端设备A的用于切换小区的信息和终端设备B的用于切换小区的信息以码分复用的形式承载在资源#1上，终端设备A接收资源#1上的符号，乘以终端设备A被分配的正交码后得到包括终端设备A的用于切换小区的信息的符号，同理，终端设备B通过终端设备B被分配的正交码后可以终端设备B的用于切换小区的信息。
可选地，终端设备的正交码可以是网络设备#1为其分配的密钥，终端设备根据被分配的该密钥解码分复用后得到用于切换小区的信息。
再例如，终端设备A的用于切换小区的信息和终端设备B的用于切换小区的信息以频分复用的形式承载在资源#1上，每个终端设备的用于切换小区的信息按照预定义的规则映射在资源#1的不同频带资源上，终端设备根据预定义的规则在资源#1上确定承载该终端设备的用于切换小区的信息。
可选地，每个终端设备的用于切换小区的信息由网络设备#1为该终端设备分配的密钥加扰，可以提高保密性，避免其他终端设备获取到该终端设备的专用的用于切换小区的信息。

其中，信元B的具体实施方式可以参考上述图3中的描述，为了简要，在此不再赘述。
可选地，终端设备A和终端设备B可以是同一切换条件，也可以是不同的切换条件，本申请对此不作限定。
可选地，信息C还可以包括多个目标小区的用于切换的信息，也就是说，信息C可以包括网络设备#2的小区的信息以及切换至该小区的切换条件，还可以包括网络设备#3的小区的信息以及切换至该小区的切换条件。在终端设备满足其中一个小区的切换条件的情况下，终端设备发起切换，切换至该满足切换条件的小区。
根据上述方案，通过公共信令如第一信息调度承载多个终端设备的用于切换小区的信息的第一资源，能够减小信令开销，提高资源利用率。

信息D用于指示资源#2，该资源#2用于承载于该信息D对应的终端设备的用于切换小区的信息。例如，终端设备A的信息D1指示的资源#2，可以记做资源#2A，用于承载终端设备A的用于切换小区的信息，终端设备B的信息D2指示的资源#2，可以记做资源#2B，用于承载终端设备B的切换小区的信息。
根据上述方案，通过将调度每个终端设备的用于切换小区的信息的控制信息(即第二信息)承载在下行共享信道中，通过第一信息调度承载多个终端设备的该第二信息的资源，能够减小下行控制信道的信令开销，提高下行控制信道的资源利用率，并且能够减小对现有技术修改的工作量(相比于可能一中对承载用于切换小区的信息的信息C做利用公共的密钥的加解密，可能二中的方案中用于切换小区的信息的可以延用现有的加解密机制，而可以不对信息D做额外的加解密，这样可以避免了引入新的加解密机制(如利用终端设备组的密钥(也称为公共的密钥)进行的加解密)，由于加解密机制设计到底层算法的修改，所以该方案对现有的通信系统改动较小)，加快通信标准化进度。此外，该方案无需发送 过大的消息，降低解码难度，提高了解码鲁棒性，在信道质量较差的情况下终端设备仍然能正确地解码得到切换命令。
