图1示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括终端设备(也可简称为终端)和网络设备。
本公开实施例涉及的终端设备，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等。在不同的系统中，终端设备的名称可能也不相同，例如在5G系统中，终端设备可以称为用户设备(User Equipment，UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network，CN)进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，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 Initiated 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。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device)，本公开实施例中并不限定。
本公开实施例涉及的网络设备，可以是基站，该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同，基站又可以称为接入点，或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备，或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol，IP)分组进行相互更换，作为无线终端设备与接入网的其余部分之 间的路由器，其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如，本公开实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications，GSM)或码分多址接入(Code Division Multiple Access，CDMA)中的网络设备(Base Transceiver Station，BTS)，也可以是带宽码分多址接入(Wide-band Code Division Multiple Access，WCDMA)中的网络设备(NodeB)，还可以是长期演进(long term evolution，LTE)系统中的演进型网络设备(evolutional Node B，eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB)，也可以是家庭演进基站(Home evolved Node B，HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等，本公开实施例中并不限定。在一些网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)节点，集中单元和分布单元也可以地理上分开布置。

下面首先对本公开实施例提供的方案涉及的内容进行介绍。
相关技术中引入了条件切换(Conditional Handover,CHO)。其中，网络为UE(终端)提前预配置一定数量的小区作为UE切换的备选小区，并配置一定的切换条件。UE收到配置后，当某备选小区满足配置的切换条件时，UE就根据条件自动切换到该满足条件的小区。配置条件切换时，也可以针对已配置双连接(Dual Connectivity,DC)的UE进行配置，可以同时配置备选的MN(主节点)和SN(辅节点)。目前，在配置备选MN和SN时，配置SN时可以支持配置为多个条件SN。
具体的，为了增加移动性的健壮性和可靠性，第三代合作伙伴计划(3rd  Generation Partnership Project，3GPP)标准协议中定义了条件切换。在条件切换情况下，网络侧给UE预配置多个备选目标小区，提前将备选目标小区的配置信息以和执行条件发送给UE。当UE收到配置信息后，并不如普通切换一样立即执行切换；而是对备选目标小区根据配置执行条件和配置信息进行检测，当任意备选目标小区满足配置的执行条件后，UE则执行条件切换。UE接入目标小区后，发起条件切换配置的节点会收到UE接入成功某目标小区的指示，该指示来自UE或接入成功的目标小区所在节点。发起配置的节点根据情况可以释放其它预配置的备选小区。
在配置条件切换时，UE可以是建立了双连接配置的,即包含MN(主小区组(Master Cell Group，MCG))和SN(辅小区组(Secondary Cell Group，SCG))；所以在这种情况下备选目标小区包含主小区(Primary Cell，PCell)和主辅小区(Primary Secondary Cell，PScell)，也就是包括MN和SN两个节点的组合。针对一个备选目标MN节点可以配置多个条件添加的SN(即多个备选目标SN)。
为配置双连接DC的UE配置条件切换CHO时，备选切换目标也包含两个节点即MN和SN。
基于以上，本公开实施例提供了一种信息传输方法、装置及设备，用以解决相关技术中针对条件切换进行配置的方案无法支持一个备选目标MN配置多个SN的问题。其中，方法、装置及设备是基于同一申请构思的，由于方法、装置及设备解决问题的原理相似，因此方法、装置及设备的实施可以相互参见，重复之处不再赘述。
