在步骤310中，终端判断第一数值与第二数值的大小关系。
在步骤311中，若第一数值大于或者等于第二数值，终端选取第一通信网络为目标通信网络并注册到第一通信网络。
在步骤312中，若第一数值小于第二数值，终端选取第二通信网络为目标通信网络并注册到第二通信网络。
其中，获取目标通信网络的方法可以为步骤308到步骤312中介绍的方法，也可以是终端获取第二列表中排序前N个第一Wi-Fi热点信号中对应的通信网络为第一通信网络的Wi-Fi热点信号的信号强度集合，得到第一信号强度集合；终端获取N个第一Wi-Fi热点信号中除第一通信网络对应的Wi-Fi热点信号之外的其它Wi-Fi热点信号的信号强度集合，得到第二信号强度集合；比较第一信号集合中Wi-Fi热点信号的信号强度最大的信号强度与第二信号集合中Wi-Fi热点信号的信号强度最大的信号强度之间的大小关系，若第一信号集合中Wi-Fi 热点信号的信号强度最大的信号强度大于或者等于第二信号集合中Wi-Fi热点信号的信号强度最大的信号强度，则选择第一通信网络为目标通信网络；若第一信号集合中Wi-Fi热点信号的信号强度最大的信号强度小于第二信号集合中Wi-Fi热点信号的信号强度最大的信号强度，则选择第二通信网络为目标通信网络。其中，获取目标通信网络的方法还可以通过步骤308到步骤312的方法与上述方法结合获得，还可以是其他有效的选取方法。
在步骤313中，当注册到目标通信网络时，终端判断预设时间内能否通过目标通信网络获取通信服务。

步骤313当注册到目标通信网络时，终端判断预设时间内能否通过目标通信网络获取通信服务之后，可以选择执行步骤314～步骤316或者步骤317～步骤319，若预设时间内能够通过目标通信网络获取通信服务可以选择执行步骤314～步骤316，若预设时间内不能通过目标通信网络获取通信服务可以选择执行步骤317～步骤319；
在步骤314中，若预设时间内终端能够通过目标通信网络获取通信服务，获取第一列表中与目标通信网络对应的第二Wi-Fi热点信号。
可选地，若30秒内终端可以通过确定的PLMN或者漫游网络获取电话业务或者数据流量业务时，终端选取APscanned列表中与PLMN或者漫游网络对应的Wi-Fi热点信号，得到第二Wi-Fi热点信号。

可选地，若第二Wi-Fi热点信号种型号强度最强的Wi-Fi热点信号已存储在APfound列表中，不做任何处理。
在步骤317中，若预设时间内终端不能通过目标通信网络获取通信服务，统计预设时间内不能通过目标通信网络获取通信服务的次数。
在步骤318中，终端判断预设时间内不能通过目标通信网络获取通信服务的次数与第二预设阈值之间的关系。
在步骤319中，若预设时间内不能通过目标通信网络获取通信服务的次数大于第二预设阈值，终端将第二列表中的目标通信网络对应的Wi-Fi热点信号的标识信息从预设热点数据库中删除。
可选地，终端可以通过表2中的Wi-Fi热点信号划分标准来标识Wi-Fi热点信号的格数，在表2中，dBm是信号强度大小的单位，为毫分贝瓦。当30秒内终端不能通过目标通信网络PLMN或者漫游网络获取通信服务的次数大于第二预设阈值时，终端可以删除APfound列表中目标通信网络PLMN或者漫游网络对应的信号格数超过4格的Wi-Fi热点信号从预设热点数据库中删除。
表2 Wi-Fi热点信号划分标准
WiFi信号强度RSSI 信号格数
RSSI≥-65dBm 4
-75dBm≤RSSI＜-65dBm 3
-85dBm≤RSSI＜-75dBm 2
-90dBm≤RSSI＜-85dBm 1
RSSI＜-90dBm 0
在步骤320中，若第一通信网络的信号强度大于或者等于第一预设阈值，终端选取第一通信网络为目标通信网络并注册到目标通信网络。
在步骤321中，若第一通信网络的信号强度小于第一预设阈值，且第二通信网络的信号强度大于或者等于第一预设阈值，终端选取第二通信网络为目标通信网络并注册到目标通信网络。
