Description

一种减小WiF i和LTE间干扰的方法和装置 技术领域
本发明涉及通信技术领域，尤其涉及一种减小WiFi和LTE间干扰的方法和装置。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案 进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
本发明实施例提供了一种减小WiFi和LTE间干扰的方法，如图2所示，该方法包括：
步骤201、确定LTE网络是否工作。
步骤202、若所述LTE网络工作，则获取所述LTE网络的工作状态，所述LTE网络的工作状态包括所述LTE网络的工作频点。
由于LTE可支持多个不同的频段，因此，需要获取当前LTE网络的工作状态，即当前LTE网络的工作频点，根据该工作频点，可以确定当前LTE网络的工作频段。示例的，若所述LTE网络工作，获取的当前LTE网络的工作频率为2385MHz，根据2385MHz的工作频率，可以确定当前LTE网络的工作频段为B40。可选的，也可以直接获取当前LTE网络的工作频段和工作频点。
步骤203、根据所述LTE网络的工作状态和预设规则确定WiFi工作信道，所述预设规则包括所述LTE网络的工作状态与WiFi信道之间信道干扰参数的对应关系。
其中，所述信道干扰参数包括当不限于信道干扰值、吞吐量等。
方式一：当信道干扰参数为信道干扰值时，所述根据所述LTE网络的工作状态和预设规则确定WiFi工作信道包括：
(a1)根据所述LTE网络的工作状态和预设规则，确定第一WiFi信道，所述第一WiFi信道为信道干扰值小于第一阈值的WiFi信道。
表1
Figure PCTCN2014094565-appb-000001
Figure PCTCN2014094565-appb-000002
其中，该预设规则可以如表1中所示，其中，第一行表示LTE网络的工作频段和工作频点(表1中以LTE网络的工作频段为B40，带宽为20M为例进行说明)，第一列表示WiFi信道(共13个，记为Chan1-Chan13)，第二行表示在第一行所示的工作频段下各个工作频点(表1中以2360MHz-2390MHz且每个工作频点之间间隔5MHz为例进行说明)。具体的，当LTE网络工作在2390MHz时，LTE B40频段2390MHz信道对WiFi信道Chan1的干扰为56dB，LTE B40频段2390MHz信道对WiFi信道Chan2的干扰为32dB，依次类推，LTE B40频段2390MHz信道对WiFi信道Chan13的干扰为0dB，一般的，第M行第N列中的信道干扰参数表示在当前LTE网络的工作频段和工作频点的情况下对某一WiFi信道的信道干扰值(该信道干扰值可用dB表示)。需要说明的是，表1仅为对预设规则的示例 性说明，其他任何可以表示该预设规则的方式均属于本发明所要保护的范围，同时，对于不同的终端设备，表1中的具体数值可根据实际的调测进行设置。
根据表1所示的，当LTE网络工作在LTE B40频段，带宽为20M，且工作频率为2390MHz时，WiFi信道从Chan1-Chan13的信道干扰值逐渐减小，因此，可以将信道干扰值小于第一阈值的WiF i信道作为第一WiFi信道，此时，第一WiFi信道与当前LTE网络的工作状态之间的干扰较小。如表1所示，假设第一阈值为0dB，则第一WiFi信道包括Chan7-Chan13。
(a2)选取所述第一WiFi信道中未被占用的任一信道为所述WiFi工作信道。
根据(a1)中所述的，若选取Chan7-Chan13作为第一WiFi信道，那么，从Chan7-Chan13中选取一个未被占用的信道作为WiFi工作信道。示例的，当Chan7已经被占用时，则此时选择Chan7会造成信道冲突，因此，可以从Chan8-Chan13中选取未被占用的一个WiFi信道作为WiFi工作信道。
方式二：当信道干扰参数为吞吐量时，所述根据所述LTE网络的工作状态和预设规则确定WiFi工作信道包括：
(b1)根据所述LTE网络的工作状态和预设规则，确定第二WiFi信道，所述第二WiFi信道为吞吐量大于或等于第二阈值的WiFi信道。
表2
Figure PCTCN2014094565-appb-000003
Figure PCTCN2014094565-appb-000004
其中，该预设规则可以如表2中所示，其中，第一行表示LTE网络的工作频段和工作频点(表2中以LTE网络的工作频段为B40，带宽为20M为例进行说明)，第一列表示WiFi信道(共13个，记为Chan1-Chan13)，第二行表示在第一行所示的工作频段下各个工作频点(表2中以2360MHz-2390MHz且每个工作频点之间间隔5MHz为例进行说明)。具体的，当LTE网络工作在2390MHz时，WiFi信道Chan1的吞吐量为OMbps，WiFi信道Chan2的吞吐量为OMbps，以此类推，WiFi信道Chan13的吞吐量为54Mbps，一般的，第M行第N列中的吞吐量表示在当前LTE网络的工作频段和工作频点的情况下，某一WiFi信道的吞吐量。需要说明的是，表2仅为对预设规则的示例性说明，其他任何可以表示该预设规则的方式均属于本发明所要保护的范围，同时，对于不同的终端设备，表2中的具体数值可根据实际的调测进行设置。
根据表2所示的，当LTE网络工作在LTE B40频段，带宽为20M，且工作频率为2390MHz时，WiFi信道从Chan1-Chan13的吞吐量逐渐增大，而吞吐量的增大则意味着两个信道之间的干扰减小，因此，可以将吞吐量大于或等于第二阈值的WiFi信道作为第二WiFi信道，此时，第二WiFi信道与当前LTE网络的工作状态之间的干扰较小。如表2所示，假设第 二阈值为54Mbps，则第二WiFi信道包括Chan7-Chan13。
(b2)选取所述第二WiFi信道中未被占用的任一信道为所述WiFi工作信道。
根据b1中所述的，若选取Chan7-Chan13作为第二WiFi信道，那么，从Chan7-Chan13中选取一个未被占用的信道作为WiFi工作信道。示例的，当Chan7已经被占用时，则此时选择Chan7会造成信道冲突，因此，可以从Chan8-Chan13中选取未被占用的一个WiFi信道作为WiFi工作信道。
进一步的，如图3所示，在步骤201之前，所述方法还包括：
步骤200、开启WiFi热点功能。
如图3所示，在步骤201之后，所述方法还包括：
步骤204、当所述LTE网络未工作，选取所述WiFi信道中未被占用的任一信道为所述WiFi工作信道。
具体的，由于此时LTE网络未工作，因此，LTE网络与WiFi信道之间不存在干扰的问题，那么，可以选取WiFi信道(即Chan1-Chan13)中未被占用的任一信道为WiFi工作信道。
本发明实施例提供的一种减小WiFi和LTE间干扰的方法，通过检测LTE网络的工作状态，若LTE网络处于工作状态，通过获取LTE网络的工作频点，以及根据预设规则中该LTE网络的工作状态与WiFi工作信道之间信道干扰参数的对应关系，确定WiFi工作信道，根据LTE的工作状态调整终端WiFi的工作信道，使得WiFi和LTE共存时的干扰最小化，提高用户体验。
