具体实施方式
为了能够更加详尽地了解本发明实施例的特点和技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在对本发明实施例提供的小区切换的处理方法进行详细说明之前，先对相关技术小区切换过程进行简要说明。
新无线(New Radio，NR)系统支持连接态终端设备的切换过程。当正在使用网络服务的终端设备从一个小区移动到另一个小区，或由于无线传输业务负荷量调整、激活操作维护、设备故障等原因，为了保证通信的连续性和服务的质量，系统要将该终端设备与原小区的通信链路转移到新的小区上，即执行切换过程。
适用于NR系统的小区切换过程，如图1所示，包括以下三个阶段：
阶段1(包括步骤1至5)，切换准备：包括测量控制和汇报，切换请求以及确认。
阶段2(包括步骤6至8)，切换执行：终端设备在收到切换命令后立即执行切换过程，即终端设备断开源小区并与目标小区连接(如执行随机接入，发送RRC切换完成消息给目标网络设备等)；辅节点(Secondary Node，SN)状态转移，数据转发。
阶段3(包括步骤9至12)，切换完成：目标小区与接入和移动管理功能(Acess and Mobility Management Function，AMF)和用户面功能(User Port Function，UPF)执行路径切换(Path Switch)，释放源网络设备的终端设备上下文。
适用于长期演进(Long Term Evolution，LTE)系统的小区切换过程，如图2所示，包括以下三个阶段：
阶段1(包括步骤S1至S6)，切换准备：包括源网络设备配置终端设备进行测量上报，源网络设备基于终端设备的测量结果向目标网络设备发送切换请求。目标网络设备同意切换请求后，目标网络设备为终端设备配置RRC消息，所述RRC消息中携带移动控制信息(Mobility Control Information)，RRC消息中还包括用于RACH的资源、小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)、目标网络设备安全算法以及目标网络设备的系统消息等。
阶段2(包括步骤S7至S11)，切换执行：源网络设备通过切换命令将Mobility Control Information转发给终端设备，终端设备收到切换命令后，向目标网络设备发起随机接入流程。同时，源网络设备发送序列号(Sequence Number，SN)状态转换(STATUS TRANSFER)给目标网络设备，用于同坐目标网络设备上行分组数据汇聚协议(Packet Data Convergence Protocol， PDCP)SN接收状态以及下行PDCP SN发送状态。
阶段3(包括步骤S12至S18)，切换完成：当终端设备成功接入目标网络设备后，目标网络设备发送路径切换请求(PATH SWITCH REQUEST)消息，以请求移动管理实体(Mobility Management Entity，MME)切换下行路径。路径切换完成后，目标网络设备指示源网络设备释放终端设备上下文，小区切换完成。
下面对conditional handover进行简要说明。
针对高速移动场景和高频部署场景存在频繁切换以及切换容易失败的问题，为LTE系统和NR系统引入conditional handover。如图3所示，终端设备与源网络设备进行小区测量、配置和报告；源网络设备和目标网络设备进行切换准备；当终端设备满足触发条件切换到目标网络设备。Conditional handover中，通过为终端设备提前配置切换(Handover，HO)命令(command)，避免了切换准备时间过长而导致的终端设备要切换的时候已经过晚的问题。并且，对于高铁场景，终端设备的运行轨迹是特定的，所以源网络设备可以提前把目标网络设备配给终端设备，并且在HO command中包含用于触发终端设备进行切换的条件，当满足所配的条件时，终端设备向目标网络设备发起接入请求。但是，在Conditional handover中可能存在如下问题：
由于源网络设备不能够明确预知终端设备什么时候触发CHO条件，因此，源网络设备不能够明确预知终端设备何时发起小区CHO。在源网络设备不能够明确终端设备已经成功进行小区切换的情况下，源网络设备仍有可能继续向终端设备发送RRC消息。而终端设备在条件切换过程中如何响应源网络设备发送的RRC消息，目前尚无有效解决方案。
基于上述问题，本发明提供一种无线资源控制消息的处理方法，本申请实施例的无线资源控制消息的处理方法可以应用于各种通信系统，例如： 全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、LTE系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。

本发明实施例提供的无线资源控制消息的处理方法的一种可选处理流程，如图5所示，包括以下步骤：
需要说明的是，本发明实施例应用于终端设备从源小区向目标小区执行条件切换的过程中，即终端设备正在从源小区向目标小区切换。其中，源小区的网络设备为源网络设备，目标小区的网络设备为目标网络设备。
步骤S201，终端设备接收RRC消息。
在一些实施例中，源网络设备不能够明确预知终端设备何时发起小区条件切换。在源网络设备不能够明确终端设备已经成功进行小区切换的情况下，源网络设备仍有可能继续向终端设备发送RRC消息。
若终端设备支持下行同时接收数据，则终端设备继续监听源网络设备的下行信道，如物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理下行共享信道(Physical Downlink Shared Channel，PDSCH)等。
在一些实施例中，所述RRC消息为源网络设备发送的RRC重配置消息。当然，RRC消息也可以是源网络设备向终端设备发送的、除RRC重配置消息以外的其他RRC消息。
步骤S202，终端设备基于所述RRC消息的内容响应所述RRC消息。
本发明实施例中，所述终端设备基于所述RRC消息的内容，继续执行所述条件切换；或者，基于所述RRC消息携带的指令执行相应的操作。
在一些实施例中，在所述RRC消息包括第一切换命令的情况下，所述终端设备停止正在执行的条件切换，基于所述第一切换命令执行小区切换。在具体实施时，终端设备基于第一切换命令中的配置信息执行小区切换。其中，所述第一切换命令用于触发所述终端设备在接收到所述第一切换命令时，立即执行小区切换；第一切换命令触发的小区切换即为本发明图1或图2所示的小区切换。
或者，在所述RRC消息包括第一切换命令的情况下，所述终端设备继续执行当前的正在执行的条件切换，若条件切换成功，即成功接入目标小区，则忽略第一切换命令。若条件切换失败，则基于所述第一切换命令执行小区切换。在具体实施时，终端设备基于第一切换命令中的配置信息执行小区切换。
在另一些实施例中，在所述RRC消息包括条件切换去配置(CHO deconfiguration)命令、且所述条件切换去配置命令包括正在执行的条件切换的第一候选小区的情况下，所述终端设备停止正在执行的条件切换。举例来说，终端设备这在执行从源小区到目标小区的条件切换，终端设备接收到包括目标小区的RRC消息，所述终端设备停止当前执行的向目标小区的条件切换。在具体实施时，终端设备还可以删除第一候选小区的条件切换配置信息。
终端设备在停止当前执行的条件切换之后，在第二候选小区满足执行条件切换的条件、且所述第二候选小区对应的第二条件切换命令有效的情况下，所述终端设备执行向所述第二候选小区的条件切换。也就是说，第二候选小区的配置信息存在于第二条件切换命令中，并且第二条件切换命令是有效的情况下，终端设备执行向所述第二候选小区的条件切换。其中， 在未配置针对所述第二条件切换命令的定时器、且所述CHO deconfiguration命令不包括第二候选小区的情况下，认为第二条件切换命令是有效的；或者，在所述CHO deconfiguration命令不包括第二候选小区、并且已配置的针对第二条件切换命令的定时器没有超时的情况下，认为第二条件切换命令是有效的。在具体实施时，终端设备向源网络设备发送RRC响应消息，所述RRC响应消息用于响应源网络设备发送的RRC消息；所述RRC响应消息用于通知源网络设备，终端设备已经停止当前执行的条件切换，删除了第一候选小区的条件配置信息，并且执行向第二候选小区的条件切换。
终端设备在停止当前执行的条件切换之后，没有满足执行条件切换的条件的第三候选小区的情况下，终端设备保持与源网络设备的连接。其中，所述第三候选小区不属于正在执行的条件切换的候选小区。在具体实施时，终端设备向源网络设备发送RRC响应消息，所述RRC响应消息用于响应源网络设备发送的RRC消息；所述RRC响应消息用于通知源网络设备，终端设备已经停止当前执行的条件切换，并且删除了第一候选小区的条件配置信息。
在又一些实施例中，在所述RRC消息包括CHO deconfiguration命令、且所述条件切换去配置命令包括第四候选小区的情况下，删除所述第四候选小区的条件切换配置信息。其中，所述第四候选小区不属于正在执行的条件切换的候选小区，即第四候选小区与第一候选小区不同。在具体实施时，若终端设备支持双连接，即终端设备支持上行方向同时发送数据，则终端设备向源网络设备发送RRC响应消息，所述RRC响应消息用于响应源网络设备发送的RRC消息。源网络设备接收到终端设备发送的RRC响应消息后，指示第四候选小区对应的源网络设备释放预留给终端设备的无线资源和配置。
本发明实施例中，若RRC消息为RRC重配置消息，则相应的RRC响 应消息为RRC重配置完成消息。
还有一些实施例中，在所述RRC消息不包括第一切换命令和条件切换去配置命令的情况下，所述终端设备忽略所述RRC消息；其中，所述终端设备忽略所述RRC消息是指终端设备针对源网络设备发送的RRC消息后，不应用所述RRC消息中的任何配置信息更新终端设备的配置信息，也不向源网络设备发送RRC响应消息。
或者，在所述RRC消息不包括第一切换命令和条件切换去配置命令的情况下，若终端设备支持上行方向同时发送数据，所述终端设备向源网络设备发送RRC拒绝消息。在具体实施时，若所述RRC消息为RRC重配置消息，则RRC拒绝消息为RRC重配置拒绝消息。RRC拒绝消息中，可以携带拒绝的原因，如终端设备正在执行条件切换。当RRC拒绝消息中携带拒绝的原因时，在RRC拒绝消息中增加cause value。本发明实施例中，若终端设备执行条件切换成功，则终端设备接入目标小区；若终端设备执行条件切换失败，则终端设备向源小区发起RRC连接重建立过程。
再一些实施例中，在所述RRC消息不包括第一切换命令和条件切换去配置命令的情况下，所述终端设备存储所述RRC消息中的配置信息。这里，终端设备存储所述RRC消息中的配置信息后，继续执行当前的条件切换，并不立即应用所述RRC消息中的配置信息。如果正在执行的条件切换成功，则终端设备删除与源网络设备相关的全部配置信息；如果正在执行的条件切换失败，则终端设备应用所述RRC消息中的配置信息更新自身的配置，并向源小区发起RRC重配置完成消息。
本发明实施例中，终端设备根据源网络设备发送的RRC消息的内容不同，执行不同的处理，如：继续当前执行的条件切换；或基于第一切换命令执行小区切换；或者停止当前执行的条件切换、删除条件切换候选小区的配置信息；或者忽略RRC消息；或者保留RRC消息中的配置信息后， 根据当前执行的条件切换的结果，删除源小区的配置信息、或者向源小区发送RRC重配置完成消息。如此，能够避免终端设备接收到RRC消息后，便触发不必要的RRC重建立过程；能够降低小区切换过程中数据的中断和损失。并且，终端设备及时向源网络设备发送候选小区的删除信息，有助于源网络设备指示候选小区释放资源，降低网络资源的浪费。
