具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
在对本申请实施例提供的小区切换方法进行详细说明之前，先对相关技术中小区切换过程进行简要说明。
当前，随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性和复杂性，3GPP国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(Enhance Mobile Broadband，eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications，URLLC)、和大规模机器类通信(Massive Machine Type Communication，mMTC)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，便如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
与LTE系统相似，新无线(New Ration，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。
以Xn接口切换过程为例，适用于LTE系统以及NR系统的小区切换过程，如图1所示，分为以下三个阶段：
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(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。
下面对CHO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，3GPP当前正在讨论为LTE和NR系统引入CHO。CHO的切换流程，如图2所示，终端设备根据源网络设备发送的目标小区的配置信息和测量配置进行小区测量、配置和报告；源网络设备和目标网络设备进行切换准备；在终端设备判断满足针对目标小区的CHO的切换执行条件的情况下，终端设备按照预先配置的CHO命令(command)执行向目标小区的切换(如触发随机接入过程和发送切换完成消息)，进而建立与目标网络设备的连接。在CHO过程中，通过为终端设备提前配置CHO command，避免了由于终端设备高速移动进入覆盖性差的区域，导致来不及或无法发送测量上报和无法接收切换命令的问题。其中，CHO command包括目标小区的配置信息和CHO的切换执行条件配置；CHO的切换执行条件配置由源网络设备确定，源网络设备将确定的CHO的切换执行条件配置通过无线资源控制(Radio Resource Control，RRC)消息发送至终端设备。
在源网络设备需要修改源小区的配置信息和CHO的目标小区的配置信息的情况下，源网络设备将修改后的源小区配置信息发送至目标网络设备，目标网络设备基于修改后源小区的配置信息生成新的CHO的目标小区配置信息；源网络设备再将修改后CHO的目标小区的配置信息和/或新的CHO的切换执行条件配置，通过RRC重配置消息发送给终端设备。但是，终端设备在接收到RRC重配置消息之前，有可能触发CHO；且UE可能使用已经失效的或修改前的CHO的目标小区的配置信息接入目标小区，导致CHO的切换失败。
本申请实施例的技术方案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)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、新无线(new radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、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、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及车辆间(vehicle to vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。

通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及车辆间(vehicle to vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。

本申请实施例提供的小区切换方法的一种可选处理流程，如图4所示，包括以下步骤：
步骤S201，终端设备接收源网络设备发送的第一指示信息，所述第一指示信息用于指示CHO的目标小区的配置信息失效。
在一些实施例中，若源网络设备需要修改所述CHO的目标小区的配置信息，源网络设备在向终端设备发送所述目标小区的新配置信息之前，向终端设备发送第一指示信息，所述第一指示信息用于指示所述CHO的目标小区的配置信息失效。
在一些实施例中，所述第一指示信息用于指示所述目标小区的索引(index)和/或标识，表征CHO的多个目标小区中与所述index和/或标识对应的一个目标小区的配置 信息失效。举例来说，存在4个CHO的目标小区，分别对应索引1、2、3和4；所述第一指示信息指示index 1时，表征index1对应的目标小区的配置信息失效。
在一些实施例中，所述第一指示信息，还用于指示所述目标小区对应的CHO的切换执行条件配置是否有效。举例来说，若所述第一指示信息指示index1对应的目标小区的配置信息失效，则第一指示信息还用于指示index1对应的目标小区的切换执行条件配置是否有效。
在一些实施例中，若第一指示信息指示目标小区对应的CHO的切换执行条件配置无效，则终端设备不执行CHO的切换流程，如终端设备不触发随机接入过程。
在一些实施例中，若第一指示信息不指示所述目标小区对应的CHO的切换执行条件配置是否有效，则终端设备确认所述CHO的切换执行条件配置有效。即第一指示信息不指示目标小区对应的CHO的切换执行条件配置是否有效的情况下，所述终端设备默认所述目标小区对应的CHO的切换执行条件配置有效。
在一些实施例中，若第一指示信息指示目标小区对应的CHO的切换执行条件配置有效，或者第一指示信息不指示目标小区对应的CHO的切换执行条件配置是否有效，则终端设备可以判断终端设备是否满足目标小区对应的CHO的切换执行条件。在终端设备不满足目标小区对应的CHO的切换执行条件的情况下，所述终端设备不执行CHO的切换流程，如终端设备不触发随机接入过程。
在终端设备满足目标小区对应的CHO的切换执行条件的情况下，针对终端设备是否接收到源网络设备发送的所述目标小区的新配置信息，终端设备执行小区切换的可选处理流程，如图5所示，若终端设备接收到源网络设备发送的所述目标小区的新配置信息，执行步骤S301；若终端设备未接收到源网络设备发送的所述目标小区的新配置信息，执行步骤S302。
步骤S301，终端设备基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。
在一些实施例中，所述目标小区的新配置信息与所述目标小区失效的配置信息存在差异，即所述目标小区的新配置信息与所述目标小区失效的配置信息不同。其中，所述目标小区的新配置信息与所述目标小区失效的配置信息不同，可以是针对所述目标小区配置的参数类型不同，也可以是针对一个参数类型的配置信息不同。
步骤S302，终端设备禁止执行针对所述目标小区的小区切换。
在一些实施例中，终端设备禁止执行针对所述目标小区的小区切换的情况下，所述 终端设备还可以执行步骤S303或者执行步骤S304。
步骤S303，终端设备停止判断是否满足所述CHO的切换执行条件，并在接收到所述目标小区的新配置信息的情况下，基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。
在一些实施例中，所述终端设备已经判断满足所述目标小区的CHO的切换执行条件，则终端设备不再继续判断是否满足所述目标小区的CHO的切换执行条件；直至终端设备接收到源网络设备发送的所述目标小区的新配置信息，终端设备基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。
如此，通过保持终端设备判断满足所述目标小区的CHO的切换执行条件的有效性，使得终端设备在接收到源网络设备发送的所述目标小区的新配置信息时，能够在最早的时间触发针对所述目标小区的小区切换，避免重新判断是否满足所述目标小区的CHO的切换执行条件带来的时延，提高小区切换的效率。
步骤S304，终端设备继续判断是否满足所述目标小区的CHO的切换执行条件，在满足所述目标小区的CHO的切换执行条件、且接收到所述目标小区的新配置信息的情况下，所述终端设备基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。
在一些实施例中，所述终端设备已经判断满足所述目标小区的CHO的切换执行条件，但是并未接收到源网络设备发送的所述目标小区的新配置信息的情况下，所述终端设备继续判断是否满足所述目标小区的CHO的切换执行条件，直至在满足所述目标小区的CHO的切换执行条件、且接收到所述目标小区的新配置信息的情况下，所述终端设备基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。
其中，所述终端设备接收源网络设备发送的所述目标小区的新配置信息，可以发生在终端设备判断满足所述目标小区的CHO的切换执行条件之后；举例来说，终端设备判断满足所述目标小区的CHO的切换执行条件之后，在下一次判断是否满足所述目标小区的CHO的切换执行条件之前，终端设备接收到源网络设备发送的所述目标小区的新配置信息，则终端设备可以基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。在该场景下，可以认为终端设备接收到源网络设备发送的所述目标小区的新配置信息时，便可以基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。
所述终端设备接收源网络设备发送的所述目标小区的新配置信息，可以发生在终端 设备判断满足所述目标小区的CHO的切换执行条件之前；举例来说，终端设备判断不满足所述目标小区的CHO的切换执行条件之后，终端设备接收到源网络设备发送的所述目标小区的新配置信息；则终端设备再一次判断是否满足所述目标小区的CHO的切换执行条件。若终端设备判断满足所述目标小区的CHO的切换执行条件，则终端设备可以基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。在该场景下，可以认为终端设备接收到源网络设备发送的所述目标小区的新配置信息之后，可以基于所述目标小区的新配置信息，执行针对所述目标小区的小区切换。
在本申请各可选实施例中，所述第一指示信息可以携带于RRC消息中，所述第一指示信息也可以携带于媒体接入控制单元(Media Access Control Control Element，MAC CE)中，所述第一指示信息也可以携带于物理下行控制信道(Physical Downlink Control Channel，PDCCH)信令中。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
本申请可选实施例中，在源网络设备需要修改CHO的目标小区的配置信息的情况下，源网络设备在向终端设备发送所述目标小区的新配置信息之前，向终端设备发送第一指示信息，指示CHO的目标小区的配置信息失效。如此，能够避免终端设备在接收到携带修改后的CHO的目标小区的配置信息之前，终端设备利用失效的CHO的目标小区的配置信息接入目标小区导致的小区切换失败的问题，提高了终端设备小区切换的成功率。
