需要说明的是，根据采用标准的不同，与WIFI频段构成干扰的LTE频段也会有所不同。当然，本发明实施例对与WIFI频段构成干扰的LTE频段不做具体的限制。
示例性地，当终端识别出自身所在LTE频段与WIFI频段构成干扰时，获取自身所在LTE频段的信号质量，具体包括：当终端识别出自身所在LTE频段与WIFI频段之间的频率间隔小于预设频率间隔时，终端获取自身所在LTE频段的信号质量。
其中，LTE频段与WIFI频段之间的频率间隔，为LTE频段的最高频率与WIFI频段的最低频率之间的频率间隔，或LTE频段的最低频率与WIFI频段的最高频率之间的频率间隔。
需要说明的是，预设频率间隔，用于判断LTE网络信号和WIFI网络信号是否容易产生干扰，当LTE频段与WIFI频段之间的频率间隔小于预设频率间隔时，说明LTE网络信号和WIFI网络信号容易产生干扰；反之，当LTE频段与WIFI频段之间的频率间隔大于预设频率间隔时，说明LTE网络信号和WIFI网络信号不易产生干扰。
根据目前通信行业频段分布的标准，TDD-LTE的频段40的频率范围为2300MHz-2400MHz、FDD-LTE的频段7的频率范围为2500MHz-2570MHz，而WIFI网络所使用的ISM频段的频率范围为：2.400MHz-2483.5MHz(参见图1所示)。可以看出，TDD-LTE的频段40，以及FDD-LTE的频段7与WIFI频段的频率间隔非常小，即满足频率间隔小于预设频率间隔，因此容 易造成LTE网络信号和WIFI网络信号的相互干扰。
示例性地，图3示出了本发明实施例提供的另一种WIFI接入方法的方法流程，参考图3，在终端识别出自身所在LTE频段与WIFI频段构成干扰之前，方法还包括：S200：当终端识别出自身发生小区重选或小区切换时，判断自身所在LTE频段与WIFI频段是否构成干扰。
需要说明的是，终端发生小区重选或小区切换时，终端所在LTE频段也会发生改变，因此在终端识别出自身发生小区重选或小区切换时，通过主动判断自身所在LTE频段与WIFI频段是否构成干扰，可以及时抑制LTE网络和WIFI网络之间的信号干扰。
优选地，当终端识别出自身发生小区重选或小区切换时，判断自身所在LTE频段与WIFI频段是否构成干扰，具体包括：当终端识别出自身发生小区重选或小区切换且终端所在LTE频段发生改变时，终端判断自身所在LTE频段与WIFI频段是否构成干扰。
S202：终端根据自身所在LTE频段的信号质量选择对应的LTE频段和WIFI频段之间的频率间隔；
其中，LTE频段和WIFI频段之间的频率间隔，为LTE频段的中心频点与WIFI频段的中心频点的频率间隔。
需要补充的是，终端所在LTE频段的信号质量越好，与该信号质量对应的LTE频段和WIFI频段之间的频率间隔就越小；反之，终端所在LTE频段的信号质量越差，与该信号质量对应的LTE频段和WIFI频段之间的频率间隔就越大。
示例性地，当终端识别出自身所在LTE频段与WIFI频段构成干扰时，获取自身所在LTE频段的信号质量具体包括：当终端识别出自身所在LTE频段与WIFI频段构成干扰时，终端周期性获取自身所在LTE频段的信号质量，并根据周期性获取的信号质量计算信号质量的波动值；相应地，终 端根据自身所在LTE频段的信号质量选择对应的LTE频段和WIFI频段之间的频率间隔，具体包括：在信号质量的波动值大于预设阈值时，终端根据自身当前周期所在LTE频段的信号质量选择对应的LTE频段和WIFI频段之间的频率间隔。
需要说明的是，信号质量的波动值为当前周期所测量的信号质量与上一个周期测量的信号质量的绝对差值。
S203：终端根据频率间隔选择对应的WIFI信道号。
其中，WIFI信道号，为WIFI网络对ISM频段进行信道划分时采用的信道标识。图4示出了WIFI信道号与WIFI频段的对应关系，根据IEEE802.11b标准，2.4-GHz-ISM频段共划分为14个WIFI信道，每个WIFI信道的带宽为22MHz，相应地，WIFI信道号为1-14。在实际应用中，根据通信标准的不同，频段的划分也会不同，本发明实施例对此不做具体的限制。
图5示出了本发明实施例提供的WIFI接入方法的第一详细实施例，参考图5，该方法包括：
S501：当终端识别出自身发生小区重选或小区切换时，获取自身所在LTE频段；
S502：终端判断自身所在LTE频段是否发生改变，若是，则执行步骤S503；
S503：终端判断自身所在LTE频段是否为TDD-LTE的频段40或者FDD-LTE的频段7，若是，则执行步骤S504；
S504：终端获取自身所在LTE频段的信号质量；
S505：终端根据自身所在LTE频段的信号质量选择对应的LTE频段和WIFI频段之间的频率间隔；
其中，表1示出了终端预设的LTE频段的信号质量SINR与LTE频段和WIFI频段之间的频率间隔的对应关系。
表1
信号质量(dB) 频率间隔(MHz)
SINR<＝10 40
10<SINR<＝20 30
20<SINR<＝30 20
30<SINR 10
S506：终端根据频率间隔选择对应的WIFI信道号。
其中，表2示出了终端预先设置的频率间隔与WIFI信道号的对应关系。例如，终端工作在TDD-LTE的频段40，且LTE频段和WIFI频段之间的频率间隔为40MHz，由于频段40的最高频率为2400MHz，因此WIFI网络的频率应至少大于2440MHz，而满足频率大于2440MHz的WIFI信道号为11-14(WIFI信道号11的频率范围为2451MHz-2473MHz)。也就是说，终端根据频率间隔40MHz选择对应的WIFI信道号11-14。
表2
频率间隔(MHz) WIFI信道号
40 11-14
30 8-14
20 6-14
10 4-14
综合步骤S501-步骤S506，终端通过选择合适的WIFI信道号，保证了终端所在LTE频段和WIFI频段之间存在一定的频率间隔，实现了有效抑制LTE网络和WIFI网络之间的信号干扰。
图6示出了本发明实施例提供的WIFI接入方法的第二详细实施例，参 考图6，该方法包括：
S601：当终端识别出自身所在LTE频段与WIFI频段构成干扰时，终端开启周期性定时器；
其中，周期性定时器，用于终端周期性获取自身所在LTE频段的SINR值。在本发明实施例中，周期性定时器设置的周期为10秒。
S602：终端在周期性定时器设置的周期到来时获取SINR值，并根据SINR值计算SINR波动值；
其中，SINR波动值为当前周期所测量的SINR值与上一个周期测量的SINR值的绝对差值。
S603：终端判断SINR波动值是否大于预设阈值，若是，则执行步骤S604；
其中，在本发明实施例中预设阈值为10dB。
S604：终端根据当前周期获取的SINR值选择对应的LTE频段和WIFI频段之间的频率间隔；
S605：终端根据频率间隔选择对应的WIFI信道号。
