Description

小区切换方法及装置、切换配置方法及装置和用户设备 技术领域
本公开涉及通信技术领域，尤其涉及一种小区切换方法及装置、切换配置方法及装置、用户设备、基站和计算机可读存储介质。
背景技术
在第四代移动通信技术(4G)的切换过程中，网络根据用户设备(User Equipment，简称UE)的测量上报结果，向切换目标小区发送切换请求，切换目标小区确认完成后，给UE发送切换命令，携带一个切换目标小区的配置信息。UE收到切换命令后，向切换目标小区发起随机接入过程。
为了提高切换的鲁棒性，第五代移动通信技术(5th Generation，简称5G)提出了基于条件的切换过程(conditional handover，简称CHO)，即网络可以提前为UE配置切换目标小区和切换触发条件，当切换触发条件得到满足时，UE自行发起切换过程，不需要网络再发送切换命令。在切换触发之前，网络可以更改切换目标小区和切换触发条件。
目前CHO只会根据信号质量来选择和配置切换目标小区和切换条件，但是不同小区提供的服务可能不同，例如多媒体广播多播业务(Multimedia Broadcast Multicast Service，简称MBMS)、直连链路(sidelink)以及其他专网业务。如果只根据信号质量来选择切换目标小区和切换条件，可能导致业务中断。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是本申请一示例性实施例示出的一种小区切换方法的流程图，该实施例从UE侧进行描述，如图1所示，该小区切换方法包括：
在步骤S101中，接收基站发送的切换配置信息，该切换配置信息包括为UE配置的切换目标小区以及为每个切换目标小区配置的第一切换条件和第二切换条件，其中，第一切换条件的切换难度低于第二切换条件的切换难度。
例如，第一切换条件可以为：服务小区的参考信号接收功率(Reference Signal Receiving Power，简称RSRP)低于-98分贝(db)，切换目标小区的RSRP高于-98db，第二切换条件为：服务小区的RSRP低于-101db，切换目标小区的RSRP高于-98db。
在步骤S102中，获取每个切换目标小区支持的业务类型。
在该实施例中，可以读取每个切换目标小区的系统信息，根据系统信息获取每个切换目标小区支持的业务类型。
在步骤S103中，根据每个切换目标小区支持的业务类型与UE所需业务，为每个切换目标小区选择所采用的切换条件。
在该实施例中，可以通过但不局限于以下方式为每个切换目标小区选择所采用的切换条件：
方式11)确定每个切换目标小区支持的业务类型与UE所需业务的匹配度，为匹配度大于预设阈值的切换目标小区选择第一切换条件，为匹配度小于或等于阈值的切换目标小区选择第二切换条件。
其中，可以根据每个切换目标小区支持的业务类型与UE所需业务的重合数量，确定匹配度。
由于第一切换条件的切换难度低于第二切换条件的切换难度，为了使UE容易切换到匹配度高的切换目标小区，因此为匹配度高的切换目标小区选择第一切换条件，为了使UE不容易切换到匹配度低的切换目标小区(即尽量保持在原小区)，因此为匹配度低的切换目标小区选择第二切换条件。
上述预设阈值可以根据需要灵活设置。
方式12)从UE所需业务中确定优先级最高的业务，为支持优先级最高的业务的切换目标小区选择第一切换条件，为不支持优先级最高的业务的切换目标小区选择第二切换条件。
其中，优先级最高的业务可以为但不局限于该UE最需要的一种业务。
由于第一切换条件的切换难度低于第二切换条件的切换难度，为了使UE容易切换到支持优先级最高的业务的切换目标小区，因此为支持优先级最高的业务的切换目标小区选择第一切换条件，为了使UE不容易切换到不支持优先级最高的业务的切换目标小区(即尽量保持在原小区)，因此为不支持优先级最高的业务的切换目标小区选择第二切换条件。
