Description

小区切换、配置方法及装置、计算机可读存储介质、用户设备、网络设备

技术领域
本发明涉及通信技术领域，尤其涉及一种小区切换、配置方法及装置、计算机可读存储介质、用户设备、网络设备。
背景技术
在无线通信中引入了一种条件切换机制。在条件切换机制中，用户设备(User Equipment,UE)判断切换执行条件是否满足，在满足条件时，UE利用切换命令中包含的候选目标小区的配置参数接入目标小区。
无线通信中还引入了一种双激活栈(Dual Active Protocol Stack,DAPS)切换。在传统的切换过程中，总会有用户面中断时间，因为一旦UE收到切换命令，UE就中断与源基站的通信，转而同步到目标小区并执行随机接入过程，当随机接入成功之后，UE才能继续与目标基站进行数据传输，这中间有一定的中断时间。为了达到0毫秒(ms)的切换时延，新引入的DAPS切换要求在切换过程中UE同时保持与源基站、以及与目标基站的通信。在这切换的过程中，UE等到UE已经与目标小区开展正常通信之后才释放与源基站的连接。
但是，在同时配置条件切换和DAPS切换的情况下，如何实现UE的小区切换是一个亟待解决的技术问题。

具体实施方式
如背景技术中所述，在同时配置条件切换和DAPS切换的情况 下，如何实现UE的小区切换是一个亟待解决的技术问题。
本发明技术方案中，通过在切换执行条件中配置第一条件和第二条件，使得UE可以基于测量结果以及切换执行条件执行DAPS切换，实现了同时配置条件切换和DAPS切换的情况下的小区切换，既能提升切换成功率也能减少切换中断时延。此外，在DAPS切换中，由于需要UE与源基站和目标基站同时保持通信，因此需要配置第一条件保证目标小区的信号质量，配置第二条件保证服务小区的质量，从而实现DAPS切换的顺利进行。
本方明技术方案可适用于5G(5Generation)通信系统，还可适用于4G、3G通信系统，还可适用于未来新的各种通信系统，例如6G、7G等。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种小区切换方法的流程图。
图1所示小区切换方法可以用于用户设备侧，也即可以由用户设备执行所述方法的各个步骤。所述用户设备包括但不限于手机、计算机、平板电脑等终端设备。
具体地，小区切换方法可以包括以下步骤：
步骤101：获取DAPS切换对应的切换执行条件(Handover execution condition)，所述切换执行条件包括第一条件和第二条件，所述第一条件指示针对候选小区信号质量的要求，所述第二条件指示针对服务小区信号质量的要求；
步骤102：测量所述候选小区的信号质量以及所述服务小区的信号质量；
步骤102和101并没有明确的先后顺序，用户设备可以一直测量候选小区和服务小区，然后从网络侧获得DAPS切换对应的切换执行 条件。服务小区可以是UE所接入的主小区，或者是在载波聚合状态下的任何一个服务小区。
步骤103：如果所述候选小区的信号质量满足所述第一条件，且所述服务小区的信号质量满足第二条件，则向所述候选小区执行DAPS切换。
需要指出的是，本实施例中各个步骤的序号并不代表对各个步骤的执行顺序的限定。
可以理解的是，在具体实施中，所述小区切换方法可以采用软件程序的方式实现，该软件程序运行于芯片或芯片模组内部集成的处理器中。
本实施例中，UE可以从切换命令中获取切换执行条件。切换执行条件可以是DAPS切换对应的切换执行条件，DAPS切换对应的切换执行条件可以包括第一条件和第二条件。之所以设置第一条件和第二条件是因为，对于DAPS切换要求UE同时与源基站和目标基站保持连接，因此两侧的信号质量均不能太差。也就是说，除了常规的对候选小区信号质量的要求之外，还需要设置服务小区的信号质量满足一定的要求。
具体地，UE还可以从切换命令中获取非DAPS切换对应的切换执行条件。非DAPS切换对应的切换执行条件可以仅包括第一条件。
具体地，UE还可以从切换命令中获取DAPS切换或非DAPS切换所针对的候选小区的标识，例如，UE建立了数据无线承载(Data Radio Bearer，DRB)DRB1、DRB2和DRB3，切换命令中包括针对候选小区cell1时，DRB1配置为DAPS切换，其对应的切换执行条件称为DAPS切换执行条件，此时DRB2和DRB3可以配置为非DAPS切换；针对候选小区cell1可以配置非DAPS切换对应的切换执行条件，即普通切换对应的切换执行条件，此时所有的DRB均没有配置为DAPS切换；针对其他候选小区如cell2，如果所有DRB均没有配 置为DAPS切换，则此时网络配置非DAPS切换对应的切换执行条件。
在步骤102的具体实施中，响应于接收到切换命令，UE测量候选小区的信号质量以及服务小区的信号质量，并判断候选小区的信号质量是否满足第一条件，以及服务小区的信号质量是否满足第二条件。例如，UE判断候选目标小区的信号质量是否比服务小区的信号质量高预定的偏移量。信号质量可以有不同的形式，如参考信号的接收功率、或者参考信号的接收质量、或者参考信号的信干噪比等。
在步骤103的具体实施中，如果目标候选小区的信号质量以及服务小区的信号质量满足DAPS切换对应的切换执行条件，则UE向目标候选小区执行DAPS切换。
具体地，UE利用切换命令中包含的候选目标小区的配置参数接入目标小区，与目标小区取得同步，在目标小区发起随机接入流程，在发送了切换完成命令(即无线资源控制(Radio Resource Control,RRC)重配置完成)之后，UE实现切换到目标小区。在切换过程中UE同时保持与源基站、以及与目标基站(也即目标小区所属基站)的通信。在切换的过程中，UE等到UE已经与目标小区开展正常通信之后且收到目标小区发送的释放源侧链路的指示之后才释放与源基站的连接。
本发明实施例实现了同时配置条件切换和DAPS切换的情况下的小区切换，既能提升切换成功率也能减少切换中断时延。
在本发明一个非限制性的实施例中，所述第一条件包括测量事件A3和/或测量事件A5和/或测量事件A4，所述第二条件包括测量事件A1。
具体地，测量事件A3(Event A3)是指同频/异频邻区信号质量比服务小区的信号质量高预定的偏移量(Neighbour becomes offset better than serving)。测量事件A5(Event A5)是指服务小区信号质量低于门限1并且邻区信号质量高于门限2(Serving becomes worse than threshold1  and neighbour becomes better than threshold2)。测量事件A4(Event A4)是指异频邻区信号质量高于预设门限(Neighbour becomes better than threshold)。上述测量事件A3、测量事件A5和测量事件A4均是对候选小区的信号质量提出要求，第一条件中可以包括测量事件A3、测量事件A5和测量事件A4中的一个或多个。
测量事件A1(Event A1)是指服务小区信号质量高于一定门限(Serving becomes better than threshold)。测量事件A1是对服务小区的信号质量提出要求，第二条件可以包括测量事件A1。
本发明实施例中，UE判断候选小区的信号质量是否满足所述测量事件A3和/或测量事件A5和/或测量事件A4，并判断服务小区的信号质量是否满足测量事件A1。如果是，则UE向候选小区执行DAPS切换。
例如，源基站配置测量事件A3/A5/A4(第一条件)和测量事件A1(第二条件)作为候选小区Cell1的切换执行条件。UE收到候选小区为UE配置的无线资源(放置在透明容器(Transparent Container)中)以及上述切换执行条件之后，就开始评估Cell1和服务小区。如果Cell1满足测量事件A3/A5/A4，并且服务小区满足测量事件A1，UE向Cell1执行切换。UE依据Cell1为UE配置的DAPS切换配置(通过Transparent Container获得)，实施DAPS切换。
反之，如果UE发现Cell1满足测量事件A3/A5/A4，但是服务小区不满足测量事件A1，此时UE执行向Cell1的切换，该切换是非DAPS切换，也即普通切换。
在本发明另一个非限制性的实施例中，所述第一条件包括测量事件A3和/或测量事件A5和/或测量事件A4，所述第二条件包括未运行定时器T310(包括T310没有超时)。
具体实施中，定时器T310是UE判断无线链路失败的一个定时器。T310运行则意味着服务小区的信号质量是比较差的，因此此处 以T310是否启动判断是否执行DAPS切换。
例如，源基站配置测量事件A3/A5/A4(第一条件)作为候选小区Cell1的切换执行条件，此时网络配置针对Cell1可以执行DAPS切换，仅满足A3/A5/A4(第一条件)只能执行普通切换。UE收到上述切换执行条件之后，就开始评估Cell1和服务小区。如果Cell1满足测量事件A3/A5/A4，并且UE未运行定时器T310(也包括T310没有超时)，UE向Cell1执行DAPS切换。UE依据Cell1为UE配置的DAPS切换配置(通过Transparent Container获得)，实施DAPS切换。
反之，如果UE发现Cell1满足测量事件A3/A5/A4，但是UE运行定时器T310(包括T310超时)，此时UE执行向Cell1的切换，该切换是非DAPS切换，也即普通切换。
本实施例以T310是否运行作为服务小区是否满足第二条件的判定依据，这是一种隐式配置第二条件的方法，需要说明的是，如果UE发现T310之前已经运行，当前已经超时，UE认为第二条件不满足。实际中还可以有其他方式用于判定服务小区是否满足第二条件，如服务小区发生了无线链路失败，或者UE发现与服务小区处于失步，均可以认为服务小区信号质量不满足要求，UE不能执行DAPS切换。换言之，本发明实施例中第二条件可以是服务小区未发生无线链路失败或与服务小区保持同步。
在本发明一个非限制性的实施例中，UE需要获取要执行DAPS切换的数据无线承载。
具体地，UE可以从切换命令中获取需要执行DAPS切换的数据无线承载(Data Radio Bearer,DRB)，例如该数据无线承载的标识。
进一步地，在执行DAPS切换时，UE将所述数据无线承载的PDCP实体配置为用于DAPS切换的PDCP实体，所述用于DAPS切换的PDCP实体能够同时处理来自所述服务小区以及所述目标候选 小区的数据。
例如，针对数据无线承载DRB1采用DAPS切换的情况，UE将DRB1的PDCP实体重配置为用于DAPS切换的PDCP实体。此时该PDCP实体可以同时处理来自源基站侧和目标基站侧的数据。UE在实施接入候选小区Cell1时，继续维持与服务小区的连接，在UE成功接入Cell1之后，UE同时与服务小区和Cell1保持数据传输，等到Cell1向UE发送释放源侧的连接的命令时，UE才会释放与服务小区的连接。
相应地，请参照图2，图2所示的切换配置方法可以用于网络设备侧，例如源基站(也可以称为服务基站)侧。
具体地，所述切换配置方法可以包括以下步骤：
步骤201：配置DAPS切换对应的切换执行条件，所述切换执行条件包括第一条件，或者所述切换执行条件包括所述第一条件和第二条件，所述第一条件指示针对候选小区信号质量的要求，所述第二条件指示针对服务小区信号质量的要求；
步骤202：发送所述切换执行条件，所述切换执行条件用于在目标候选小区的信号质量满足所述第一条件，且所述服务小区的信号质量满足第二条件时，向所述候选小区执行DAPS切换。
本实施例中，切换执行条件可以是携带于切换命令中发送出去的。
例如，一个UE建立了3个承载，DRB1、DRB2和DRB3，其中DRB1的服务质量参数要求较高，要求数据传输时延较短，因此服务基站(在切换之前为源基站)准备为DRB1配置DAPS切换，而其他两个DRB不配置DAPS切换。同时为了满足切换的成功率，服务基站打算为UE配置条件切换。服务基站在收到UE发送的测量报告之后，发现UE已经不在小区的中心区域，为了满足移动性，服务基站依据UE上报的测量报告，选择Cell1、Cell2作为UE切换的候选小 区。那么源基站(在与候选基站协商之后)可以通过切换命令指示针对候选小区Cell1，DRB1配置为DAPS切换，其他两个DRB为非DAPS切换，以及相应的切换执行条件；指示候选小区Cell2为非DAPS切换(也即条件切换)，以及相应的切换执行条件。
在一个具体的实施例中，源基站可以配置第一条件包括测量事件A3和/或测量事件A5和/或测量事件A4，所述第二条件包括测量事件A1。在这种情况下，切换命令包括第一条件和第二条件。也就是说，源基站以显式配置的方式配置切换执行条件。切换命令可以通过一条RRC信令或者多条RRC信令向UE发送，即可以同时发送第一条件和第二条件，也可以分别发送第一条件和第二条件。
在一个具体的实施例中，第一条件包括测量事件A3和/或测量事件A5和/或测量事件A4，所述第二条件包括未运行定时器T310(包括T310没有超时)。在这种情况下，切换命令中仅包括第一条件。也就是说，源基站以隐式配置的方式配置DAPS切换对应的切换执行条件，信令开销更小。
请参照图3，图3示出了一种交互流程图。
在步骤301中，源基站302向候选目标基站303发送切换请求。
在步骤302中，源基站302向候选目标基站304发送切换请求。
具体实施中，源基站302依据UE301上报的测量报告，选择候选小区Cell1、Cell2和Cell3作为UE301切换的候选小区，源基站302可以依次向这三个小区所属的基站(即候选目标基站303和候选目标基站304)发送切换请求。候选小区Cell3所属的基站未在图中示出。切换请求中指示是条件切换。
在具体实施中，源基站302向Cell1所属基站(候选目标基站303)发送的切换请求中指示本次切换是条件切换，以及指示DRB1请求配置为DAPS切换，其他两个DRB为非DAPS切换，切换请求中不需要向候选目标基站303指示切换执行条件。
源基站302向Cell2所属基站(候选目标基站304)发送的切换请求中指示本次切换是条件切换。源基站302基于UE301支持的带宽组合判断UE301从服务小区切换到Cell2不能支持DAPS切换，因此切换请求中没有包含DAPS切换的信息。
源基站302向Cell3所属基站发送的切换请求中指示本次切换是条件切换，以及指示DRB1配置为DAPS切换，其他两个DRB为非DAPS切换。
在步骤303中，候选目标基站303向源基站302发送切换请求确认。
在步骤304中，候选目标基站304向源基站302发送切换请求确认。
具体实施中，候选目标基站303和304可以基于自身的负载水平，决定是否接受切换请求，如果接受，为UE配置必要的无线资源，然后向源基站返回切换请求确认(可以称为Handover Request Acknowledge，或者Handover Preparation Acknowledge)；如果不接受，则向源基站返回请求失败。
具体实施中，对于候选目标基站303，如果接受切换请求，可以存在两种处理：
1、候选目标基站303可以配置仅支持条件切换的无线资源(即仅用于条件切换的无线资源配置，该配置中不包含DAPS切换信息)，然后向源基站302返回切换请求确认；
2、候选目标基站303可以配置支持条件切换和DAPS切换的无线资源，对于本场景，候选目标基站303配置DRB1为DAPS切换，为UE额外配置DAPS相关的参数，具体可以是功控参数，比如配置在DAPS切换过程中上行功率共享的模式(uplinkPowerSharingDAPS-Mode)，配置的无线参数等，以供UE301判断Cell1满足切换执行条件之后应用。
候选目标基站303可以通过两条独立的接口信令分别向源基站指示仅配置支持条件切换的无线资源、和配置支持条件切换和DAPS切换的无线资源。
候选目标基站303还可以在一条切换请求确认消息中同时指示仅配置支持条件切换的第一无线资源配置(Target NG-RAN node To Source NG-RAN node Transparent Container 1)、和配置支持条件切换和DAPS切换的第二无线资源配置(Target NG-RAN node To Source NG-RAN node Transparent Container 2)。通常候选目标基站为UE配置的无线资源均放置在一个透明容器(Transparent Container)中，源基站不需要解析这个容器中的内容，直接发送给UE。如果在一条切换请求确认消息中同时指示仅配置支持条件切换的无线资源(以Transparent Container 1表示)、和配置支持条件切换和DAPS切换的无线资源(以Transparent Container 2表示)，候选目标基站需要向源基站明确Transparent Container对应的配置是哪一种。候选目标基站可以指示Transparent Container 2配置了DAPS(通过额外的信元指示)，而Transparent Container 1没有配置DAPS；或者仅指示Transparent Container 2配置了DAPS，默认没有指示配置DAPS的Transparent Container 1是不包含DAPS的。
对于候选目标基站304仅需要配置条件切换对应的无线资源，然后通过切换请求确认发送给源基站302。候选小区Cell3所属的基站可以采用与候选目标基站303相同的处理机制。
在步骤305中，源基站302向UE301发送切换命令。
具体地，源基站302收到不同候选目标基站返回的切换请求确认后，配置相应的切换执行条件，携带于切换命令中发送给UE。不同的候选小区可以配置不同或相同的切换执行条件。
在步骤306中，UE301测量并评估候选小区的信号质量以及服务小区的信号质量。
在步骤307中，UE301在候选小区满足切换执行条件时，执行切换。
具体实施中，对于候选小区Cell1，有两种无线资源配置，源基站302可以设置不同的切换执行条件，源基站302除了沿用原有的切换执行条件如事件A3和/或A5和/或A4，，还需要设置服务小区的信号质量满足一定的要求，比如可以增加事件A1，此时切换执行条件包含A3/A5/A4+A1，分别针对候选目标小区和服务小区。如传输透明容器(Transparent Container 2)是配置了DAPS的条件切换，源基站302配置A3/A5/A4+A1作为Cell1的切换执行条件，UE收到Transparent Container 2以及A3/A5/A4+A1的切换执行条件之后，就开始评估Cell1和服务小区，如果Cell1满足A3/A5/A4，并且服务小区满足A1，UE向Cell1执行切换，UE依据Cell1为UE配置的DAPS切换配置(通过Transparent Container 2)，实施DAPS切换，即针对DRB1采用DAPS切换，UE将DRB1的PDCP实体重配置为用于DAPS切换的PDCP实体，此时该PDCP实体可以同时处理来自源侧和目标侧的数据，UE在实施接入Cell1时，继续维持与服务小区的连接，在UE成功接入Cell1之后，UE同时与源服务小区和Cell1保持数据传输，等到Cell1向UE发送释放源侧的连接时，UE才会释放与源侧的连接。
在一个可选实施例中，对于配置了DAPS的条件切换的候选小区Cell1，源基站可以不显式配置切换执行条件，沿用现有A3/A5/A4判断邻区是否满足切换条件；同时UE依据服务小区的信号质量如是否启动T310判断是否执行DAPS切换，当T310没有运行(包括没有超时)时，UE执行DAPS切换；否则UE执行非DAPS切换。
对于候选小区Cell2，源基站302可以仅设置A3/A5/A4的切换执行条件，以便UE针对Cell2评估是否满足切换执行条件。
对于候选小区Cell3，源基站302可以设置A3/A5/A4+A1的切换执行条件，或者仅设置A3/A5/A4的切换执行条件，UE对于DAPS 切换额外采用T310进行判断。
在一个可选实施例中，对于配置了DAPS的条件切换的候选小区Cell1，源基站可以设置切换执行条件包含A3/A5/A4+A1用于判断是否执行DAPS切换，可以设置切换执行条件包含A3/A5/A4用于判断普通的非DAPS切换。对于DAPS切换执行条件中的A3/A5/A4，与非DAPS切换执行条件中的A3/A5/A4，其门限可以相同，也可以不同。以A3事件为例(候选小区比服务小区的信号质量高预定的偏移量)，DAPS切换执行条件中的A3对应的偏移量可以与非DAPS切换执行条件中的A3对应的偏移量相同；也可以设置非DAPS切换执行条件中的A3对应的偏移量取更高的值如取值为3db，而DAPS切换执行条件中的A3对应的偏移量取较低的值如取0db，这样使得UE较易触发DAPS切换，便于减少切换中断时延。如果切换执行条件是A4事件(候选小区信号质量高于预设门限)，此时可以设置非DAPS切换执行条件中A4事件设置更高门限。相应地，如果切换执行条件是A5事件(服务小区信号质量低于门限1并且候选小区信号质量高于门限2)，则可以设置非DAPS切换执行条件中门限2更高，门限1更低，以使得UE更容易触发DAPS切换。
在步骤S308中，UE301与候选目标基站303之间执行随机接入。
在步骤S309中，UE301向候选目标基站303发送RRC重配置完成。
关于UE与基站之间通过随机接入的流程接入目标小区可参照现有技术，此处不再赘述。
请参照图4，本发明实施例还公开了一种小区切换装置40。小区切换装置40可以包括：

请参照图5，本发明实施例还公开了一种切换配置装置50。切换配置装置50可以包括：
配置模块501，用于配置DAPS切换对应的切换执行条件，所述切换执行条件包括第一条件和第二条件，所述第一条件指示针对候选小区信号质量的要求，所述第二条件指示针对服务小区信号质量的要求；
发送模块502，用于发送所述切换执行条件，所述切换执行条件用于在目标候选小区的信号质量满足所述第一条件，且所述服务小区的信号质量满足第二条件时，向所述候选小区执行DAPS切换。
在具体实施中，上述切换配置装置可以对应于网络设备中具有切换配置功能的芯片，例如SOC(System-On-a-Chip，片上系统)、基带芯片等；或者对应于网络设备中包括具有切换配置功能的芯片模组；或者对应于具有数据处理功能芯片的芯片模组，或者对应于网络设备。
关于所述小区切换装置40或切换配置装置50的工作原理、工作方式的更多内容，可以参照图1至图3中的相关描述，这里不再赘述。
关于上述实施例中描述的各个装置、产品包含的各个模块/单元，其可以是软件模块/单元，也可以是硬件模块/单元，或者也可以部分是软件模块/单元，部分是硬件模块/单元。例如，对于应用于或集成于芯片的各个装置、产品，其包含的各个模块/单元可以都采用电路等硬件的方式实现，或者，至少部分模块/单元可以采用软件程序的方式实现，该软件程序运行于芯片内部集成的处理器，剩余的(如果有)部分模块/单元可以采用电路等硬件方式实现；对于应用于或集成于芯片模组的各个装置、产品，其包含的各个模块/单元可以都采用电路等硬件的方式实现，不同的模块/单元可以位于芯片模组的同一组件(例如芯片、电路模块等)或者不同组件中，或者，至少部分模块/单元可以采用软件程序的方式实现，该软件程序运行于芯片模组内部集成的处理器，剩余的(如果有)部分模块/单元可以采用电路等硬件方式实现；对于应用于或集成于终端的各个装置、产品，其包含的各个模块/单元可以都采用电路等硬件的方式实现，不同的模块/单元可以位于终端内同一组件(例如，芯片、电路模块等)或者不同组件中，或者，至少部分模块/单元可以采用软件程序的方式实现，该软件程序运行于终端内部集成的处理器，剩余的(如果有)部分模块/单元可以采用电路等硬件方式实现。
请参照图6，本发明实施例还公开了一种切换配置方法，所述切换配置方法可以用于候选目标基站侧，也即可以由候选目标基站执行所述方法的各个步骤。
具体地，所述切换配置方法可以包括以下步骤：
步骤601：接收切换请求，所述切换请求指示条件切换请求；
步骤602：配置针对非DAPS切换的第一无线资源配置以及针对DAPS切换的第二无线资源配置；
步骤603：发送所述第一无线资源配置以及所述第二无线资源配置。
本实施例中，候选目标基站可以于自身的负载水平，决定是否接受切换请求，如果接受，则为UE配置必要的无线资源，然后向源基站返回切换请求确认(可以称为Handover Request Acknowledge，或者Handover Preparation Acknowledge)。如果不接受，则向源基站返回请求失败。
具体地，候选目标基站在接受切换请求之后，可以存在下述两种处理：
1、候选目标基站可以配置仅支持条件切换的第一无线资源配置(即仅用于条件切换的无线资源配置，该配置中不包含DAPS切换信息)，然后通过向源基站返回切换请求确认；
2、候选目标基站可以配置支持条件切换和DAPS切换的第二无线资源配置。例如，候选目标基站配置DRB1为DAPS切换，为UE额外配置DAPS相关的参数，比如配置在DAPS切换过程中上行功率共享的模式(uplinkPowerSharingDAPS-Mode)，配置的无线参数。
在一个非限制性的实施例中，候选目标基站可以在两条独立的信令中分别发送所述第一无线资源配置以及所述第二无线资源配置。所述两条独立的信令为X2/Xn接口信令，或者新增信令。
其中，5G基站之间可以通过Xn接口来传输数据。4G基站和5G基站之间通过X2接口传输数据。也就是说，第一无线资源配置以及第二无线资源配置可以通过基站之间的接口进行传输。候选目标基站可以通过两条独立的接口信令分别向源基站指示仅配置支持条件切换的无线资源、和配置支持条件切换和DAPS切换的无线资源。
在另一个非限制性的实施例中，候选目标基站可以发送切换请求确认，所述切换请求确认包括所述第一无线资源配置以及所述第二无线资源配置。
本实施例中，第一无线资源配置以及第二无线资源配置可以携带于切换请求确认中发送出去。
在一个非限制性的实施例中，所述切换请求确认包括第一透明容器和第二透明容器，所述第一透明容器放置所述第一无线资源配置，所述第二透明容器放置所述第二无线资源配置。
进一步地，所述切换请求确认包括指示信息，所述指示信息指示所述第二透明容器对应DAPS切换，或者，所述指示信息指示所述第一透明容器对应非DAPS切换，以及所述第二透明容器对应DAPS切换。
具体实施中，候选目标基站在一条切换请求确认消息中同时指示仅配置支持条件切换的第一无线资源配置(Target NG-RAN node To Source NG-RAN node Transparent Container 1)、和配置支持条件切换和DAPS切换的第二无线资源配置(Target NG-RAN node To Source NG-RAN node Transparent Container 2)。通常候选目标基站为UE配置的无线资源均放置在一个透明容器(Transparent Container)中，源基站不需要解析这个容器中的内容，直接发送给UE。如果在一条切换请求确认消息中同时指示仅配置支持条件切换的无线资源(以Transparent Container 1表示)、和配置支持条件切换和DAPS切换的无线资源(以Transparent Container 2表示)，候选目标基站需要向源基站明确Transparent Container对应的配置是哪一种。候选目标基站可以指示Transparent Container 2配置了DAPS(通过额外的信元指示)，而Transparent Container 1没有配置DAPS；或者仅指示Transparent Container 2配置了DAPS，默认没有指示配置DAPS的Transparent Container 1是不包含DAPS的。
例如，候选小区Cell1所属的基站可以通过独立的信令或切换请求确认向源基站发送两种无线资源配置。候选小区Cell2所属的基站仅需要配置条件切换对应的无线资源配置，然后通过切换请求确认发送给源基站。候选小区Cell3所属的基站可以采用与候选小区Cell1所属的基站相同的处理机制。
相应地，请参照图7，本发明实施例还公开了一种切换配置方法， 所述切换配置方法可以用于源基站侧，也即可以由源基站执行所述方法的各个步骤。
具体地，所述切换配置方法可以包括以下步骤：
步骤701：发送切换请求，所述切换请求指示条件切换请求；
步骤702：接收第一无线资源配置以及第二无线资源配置，所述第一无线资源配置是针对非DAPS切换的，所述第二无线资源配置是针对DAPS切换的。
具体实施中，源基站可以通过切换命令将第一无线资源配置以及第二无线资源配置直接转发给UE。
在一个具体实施例中，源基站可以根据候选小区的网络状况确定所述候选小区应用非DAPS切换，和/或配置至少一个无线数据承载为DAPS切换；在所述切换请求中携带指示所述非DAPS切换的第一指示信息，和/或携带第二指示信息，所述第二指示信息指示请求执行DAPS切换的无线数据承载。
例如，源基站在收到UE发送的测量报告之后，发现UE已经不在小区的中心区域，为了满足移动性，源基站依据UE上报的测量报告，选择Cell1、Cell2和Cell3作为UE切换的候选小区，源基站可以依次向这三个小区所属的基站(即候选目标基站)发送切换请求：
如源基站向Cell1所属基站(基站1)发送切换请求，在切换请求中指示本次切换是条件切换，以及指示DRB1请求配置为DAPS切换，其他两个DRB为非DAPS切换，切换请求中不需要向基站1指示切换执行条件；
源基站可以向Cell2所属基站(基站2)发送切换请求，在切换请求中指示本次切换是条件切换，服务小区基于UE支持的带宽组合判断UE从服务小区切换到Cell2不能支持DAPS切换，因此切换请求中没有包含DAPS切换的信息。
源基站向Cell3所属基站(基站3)发送切换请求，在切换请求中指示本次切换是条件切换，以及指示DRB1配置为DAPS切换，其他两个DRB为非DAPS切换。
进一步地，源基站还可以根据所述第一无线资源配置以及所述第二无线资源配置分别确定条件切换执行条件和DAPS切换执行条件。
具体地，对于候选小区Cell1，有两种无线资源配置，源基站可以设置不同的切换执行条件，源基站除了沿用原有的切换执行条件，也即第一条件，如事件A3和/或A5和/或A4，还需要设置源服务小区的信号质量满足一定的要求也即第二条件，比如可以增加事件A1。或者源基站仅配置第一条件，UE在切换时判断针对源侧是否启动T310来确定是否执行DAPS切换。
具体地，对于候选小区Cell2，仅有一种无线资源配置，也即第一无线资源配置，源基站可以仅设置A3/A5/A4的切换执行条件，以便UE针对Cell2评估是否满足切换执行条件。
对于候选小区Cell3，有两种无线资源配置，源基站可以设置A3/A5/A4+A1的切换执行条件，或者源基站仅设置A3/A5/A4的切换执行条件，UE对于DAPS切换额外采用T310进行判断。
UE在收到了候选小区Cell1、Cell2、Cell3的配置，以及对应的切换执行条件，UE就评估这三个候选小区，以及评估服务小区，以确定执行相应的小区切换。
