下面，对于本示例实施方式的上述步骤进行更加详细的说明。
在步骤S210中，获取第一终端参数和网络参数。
具体地，针对一类终端可以获取第一终端参数和网络参数，一类终端可以为异构网络中的GO终端，可以理解为管理终端。异构网络中还可以包括二类终端，二类终端可以表示为GM终端，可以理解为被管理终端，一类终端相较于二类终端可以具备更多的功能，用于实现对于二类终端的管理，在一些实施例中，异构网络中的二类终端数量可以为一个或多个，本申请实施例不作限定。例如，异构网络是基于WiFi-Direct技术构建的。
此外，第一终端参数用于表征一类终端的自身运行情况，网络参数可以用于表征一类终端的网络应用情况。
在一些实施例中，第一终端参数包括：电量，网络参数包括：参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Receiving Quality，RSRQ)、接收信号强度(Received Signal StrengthIndicator，RSSI)、信噪比(signal to noise ratio，SNR)、网络时延中至少一种。此外，网络参数还可以包括其他参数，本申请实施例不作限定。
例如，RSRP是在某个符号内承载参考信号的所有资源粒子上接收到的信号功率的平均；RSRQ表示LTE参考信号接收质量，用于根据信号质量对不同LTE候选小区进行排序；RSSI在无线网络中表示信号的强度,通常随距离的增大而衰减,RSSI越接近零表示信号强度越高；SNR是规定条件下测得的有用信号电平与电磁噪声电平之间的比值。
在一些实施例中，在第一终端参数和网络参数均不满足第一预设条件时，上述方法还包括：获取第二终端参数，第二终端参数包括网络负载、中央处理器负载、图像处理器负载、终端温度中至少一种；在第二终端参数中至少一个参数满足第二预设条件时，执行异构网络切换操作。这样可以补充对于异构网络的切换条件判定，从而进一步提升对于异构网络切换的判定精度。在蜂窝覆盖更多区域的情况下，在WiFi和蜂窝组成的异构网络中实施本申请实施例可以实现针对更广泛区域的异构网络切换。
在一些实施例中，在所述第一终端参数和所述网络参数均不满足所述第一预设条件的情况下，所述方法还包括：获取所述一类终端的第二终端参数，其中，所述第二终端参数包括网络负载、中央处理器负载、图像处理器负载、终端温度中至少一种；在所述第二终端参数满足第二预设条件时，针对所述一类终端执行异构网络切换操作。
具体地，第二终端参数与第一终端参数中可以包含不同的参数，第二终端参数与第一终端参数之间可以不存在参数重叠，对于一类终端来说，还可以包括第三终端参数、第四终端参数等，一类终端的各终端参数均可以作为判定条件参与异构网络切换判定，本申请实施例不作限定。
此外，在第二终端参数中任一参数均不满足第二预设条件时，上述方法还可以包括：重新获取一类终端的第一终端参数和网络参数，并执行获取第一终端参数和网络参数之后限定的步骤，直到检测到切换条件满足时执行异构网络切换操作。
在一些实施例中，第二预设条件中可以包括：对应于第二终端参数中至少一个参数的阈值，在第二终端参数中至少一个参数满足第二预设条件时，执行异构网络切换操作包括：在网络负载大于等于第二预设条件中的网络负载阈值时，执行异构网络切换操作；或者，在中央处理器负载大于等于第二预设条件中的中央处理器负载阈值时，执行异构网络切换操作；或者，在图像处理器负载大于等于第二预设条件中的图像处理器负载阈值时，执行异构网络切换操作；或者，在终端温度大于等于第二预设条件中的终端温度阈值时，执行异构网络切换操作。
在一些实施例中，在第一终端参数和网络参数中至少一项满足第一预设条件时，执行异构网络切换操作包括：在第一终端参数满足第一预设条件中的第一子条件时，和/或，在网络参数满足第一预设条件中的第二子条件时，执行异构网络切换操作。这样可以实现基于条件判定方式的高效切换判定，从而提升通信链路的鲁棒性。
具体地，第一子条件中可以包括一个或多个阈值(如，电量阈值)，第二子条件中也可以包括一个或多个阈值(如，RSRP阈值、RSRQ阈值、RSSI阈值、SNR阈值)。
在一些实施例中，若第一终端参数中的电量小于等于第一子条件中的电量阈值，则判定第一终端参数满足第一预设条件中的第一子条件。若网络参数中的RSRP小于等于第二子条件中的RSRP阈值，则判定网络参数满足第一预设条件中的第二子条件；若网络参数中的RSRQ小于等于第二子条件中的RSRQ阈值，则判定网络参数满足第一预设条件中的第二子条件；若网络参数中的RSSI小于等于第二子条件中的RSSI阈值，则判定网络参数满足第一预设条件中的第二子条件；若网络参数中的SNR小于等于第二子条件中的SNR阈值，则判定网络参数满足第一预设条件中的第二子条件。
在一些实施例中，获取所述一类终端的第一终端参数和网络参数包括：基于预设周期获取所述一类终端的第一终端参数和网络参数。这样可以实现自动化地针对异构网络的切换判定，有利于提升异构网络切换的及时性，从而改善终端的通信服务获取效率。
具体地，预设周期可以为人为设定的也可以是查表获取的，本申请实施例不作限定，预设周期(如，20s)可以表示为数值、符号、字符串等任一形式，本申请实施例不作限定。
在步骤S220中，在第一终端参数和网络参数中至少一项满足第一预设条件时，执行异构网络切换操作。
在一些实施例中，异构网络切换操作包括组间切换操作和组内切换操作，执行异构网络切换操作包括：在当前异构网络内存在满足切换条件的目标终端时，针对目标终端执行组内切换操作；在当前异构网络内不存在满足切换条件的目标终端时，执行组间切换操作。这样可以实现基于不同条件的不同切换操作，以应对不同的情况，提升本申请实施例的鲁棒性。
在一些实施例中，针对所述一类终端执行异构网络切换操作包括：在当前异构网络内存在满足切换条件的目标终端的情况下，针对所述一类终端和所述目标终端进行所述组内切换操作，其中，所述目标终端属于二类终端；在当前异构网络内不存在满足切换条件的目标终端的情况下，针对所述一类终端进行所述组间切换操作。
具体地，除组间切换操作和组内切换操作之外，异构网络切换操作还可以包括其他类型的操作，本申请实施例不作限定。
在一些实施例中，上述方法还包括：获取当前异构网络内二类终端的终端参数和网络参数；将二类终端的终端参数和网络参数与切换条件进行比对，得到比对结果；若比对结果指示当前异构网络内存在满足切换条件的二类终端，将满足切换条件的二 类终端确定为目标终端。这样可以确定出组内切换对象(即，目标终端)，从而实现精准的组内切换，提升了异构网络切换的实施精度。
具体地，二类终端的终端参数可以包括但不限于电量；二类终端的网络参数可以包括但不限于RSRP、RSRQ、RSSI、SNR中至少一项。例如，将二类终端的终端参数和网络参数与切换条件进行比对，得到比对结果包括：将二类终端的终端参数与切换条件中的终端参数阈值进行比对，以及，将二类终端的网络参数与切换条件中的网络参数阈值进行比对，得到终端参数阈值比对结果和网络参数阈值比对结果；若终端参数阈值比对结果指示终端参数大于等于终端参数阈值，或者，网络参数阈值比对结果指示网络参数大于等于网络参数阈值，则判定比对结果指示当前异构网络内存在满足切换条件的二类终端。
具体地，若存在终端参数中存在多个参数，则将多个参数依次与切换条件中相应的阈值进行比对，若存在网络参数中存在多个参数，则也将多个参数依次与切换条件中相应的阈值进行比对。
在一些实施例中，针对目标终端执行组内切换操作包括：与目标终端进行身份互换，其中，身份互换后的目标终端属于一类终端。例如，将一类终端与目标终端进行身份互换。这样可以实现精准的组内切换，提升切换精度。
具体地，与目标终端进行身份互换包括：将一类终端的身份标识变更为二类终端对应的标识，并触发目标终端广播用于表征已变更为一类终端的消息。
在一些实施例中，执行组间切换操作包括：将当前异构网络解散，并根据选取规则确定目标异构网络；加入目标异构网络，例如，将一类终端加入目标异构网络。这样可以在无法执行组内切换时，执行组间切换，有利于终端可以及时切换到有效的异构网络。
具体地，选取规则可以用于限定异构网络的选取方式，例如，选取规则可以限定与当前终端距离最近的异构网络作为目标异构网络，其中，目标异构网络可以是多个异构网络中的任一个。加入目标异构网络包括：作为二类终端加入目标异构网络，将所述一类终端作为二类终端加入目标异构网络。
在一些实施例中，将所述一类终端加入目标异构网络包括：若存在与所述一类终端对应同一切换时机的其他终端，且其他终端不属于任一异构网络，则判定所述一类终端的加入优先级高于其他终端的加入优先级，并加入目标异构网络。这样可以提高需要组间切换的终端的优先级，从而提升需要组件切换的终端的切换效率，并降低碰 撞概率。
具体地，与一类终端对应同一切换时机的其他终端的数量可以为一个或多个，本申请实施例不作限定。
