下面结合实施例和附图对本发明进行说明。
请参见图1，图1是本发明实施例提供的一种切换方法的流程图，该方法应用于终端，如图1所示，该方法包括如下步骤：
步骤101：根据第一小区的测量结果，判断是否满足触发条件。
其中，如果判断出满足触发条件，则执行步骤102。否则，如果不满足触发条件，则执行步骤103。
可选的，上述的第一小区可为候选小区。或者，上述的第一小区与所述触发条件关联。需指出的，当第一小区与触发条件关联时，所述第一小区可为候选小区，也可不是候选小区，仅为与触发条件关联的邻小区。
此外，由于触发条件可能与服务小区有关，比如触发条件为第一小区好于服务小区多少dB才满足触发条件，因此在执行步骤101时，也可根据第一小区的测量结果以及服务小区的测量结果，来判断是否满足触发条件。
上述步骤101中的测量结果可包括但不限于以下至少一项：参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)、信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)、信道质量指示(Channel Quality Indicator，CQI)等。该测量结果所对应的测量可包括：对小区的测量，和/或对波束的测量。所述对波束的测量可包括：对以下至少一项的测量：同步信号块(Synchronization Signal and PBCH block，SSB)、解调参考信号(Demodulation Reference Signal，DMRS)、或其它参考信号。
步骤102：切换到第一小区。
可选的，如果满足触发条件，终端除了可切换到第一小区之外，还可进一步不进行测量上报，从而节省资源，减少信令开销。
此外，如果上述步骤101判断出满足触发条件，但没有配置对应的条件切换，则终端可进行测量上报。
步骤103：执行以下至少一项：不切换到所述第一小区；进行测量上报，或不进行测量上报。
需说明的是，在第一小区为候选小区的情况下，如果不满足触发条件，则终端优选进行测量上报，以便网络设备获知网络情况。而在第一小区与触发条件关联的情况下，如果不满足触发条件，则终端优选不进行测量上报，从而节省资源，减少信令开销。
本发明实施例的切换方法，可以根据第一小区的测量结果，检测是否满足触发条件，并当满足触发条件时，切换至第一小区。由此，可以增大切换成功率，从而达到保证切换成功率和低延时的效果。
本发明实施例中，触发条件可以与多个小区关联。优选的，当第一小区与触发条件关联时，所述第一小区可为：所述触发条件关联的主小区PCell。可理解的此时，终端采用的可为CA技术。
或者，当第一小区与触发条件关联时，所述第一小区可为：所述触发条件关联的特殊小区SpCell。可理解的此时，终端采用的可为DC架构。
这样，选择PCell或SpCell触发切换，可以增大切换成功率。
