In addition, portable routers that provide wireless network expansion functions also have WIFI, and routers are also under WIFI function.

If the Station connection request is detected, the Station connection response is sent, and the terminal processes the response and sends the response to the WIFI. The access point sends the required parameters and the like to access the WIFI access point. As shown in Figure 1, when the WIFI access point sends a Beacon frame, the WIFI IC, the WIFI IC peripheral circuit, and the power amplifier consume current of 12 for the WIFI access point. After the Beacon frame is sent, the current consumption of the WIFI IC and the WIFI IC peripheral circuit in the normal working state of the WIFI access point is at II in the absence of the Station terminal requesting the connection.
可见, 现有技术中, 在没有 Station 终端请求连接的情况下, WIFI 接入点在发送 Beacon帧之后消耗电流较大,这样 WIFI接入点功耗较高。 发明内容  It can be seen that, in the prior art, in the case that no station terminal requests connection, the WIFI access point consumes a large current after transmitting the Beacon frame, so that the power consumption of the WIFI access point is high.

The second power consumption mode includes a low power mode performed by the WIFI IC and a peripheral circuit of the WIFI IC. The low power mode includes: sleep, standby or shutdown, but is not limited thereto. When the WIFI access point is in the first power consumption mode, the integrated circuit of the WIFI access point and the integrated circuit of the integrated circuit can perform normal work. At this time, the WIFI access point is in a normal working state. When the WIFI access point is in the second power consumption mode, the integrated circuit of the WIFI access point and the peripheral circuit of the integrated circuit may be in a power-off state. At this time, the WIFI access point is in a sleep, standby or shutdown state. An embodiment of the present invention provides a method for reducing power consumption of a WIFI access point. When the first power consumption mode is executed, the first timer of the first power consumption mode is started, and the first timer expires. And then switching to the second power consumption mode, where the power consumption of the second power consumption mode is lower than the power consumption of the first power consumption mode, compared to the prior art, the first power consumption is always after the Beacon frame is sent. In the case of the mode, the present invention is not only in the first power consumption mode but also in the second power consumption mode in a Beacon frame period, so that the WIFI IC and the periphery of the WIFI IC in the WIFI access point are in the current Beacon frame period. The power consumption of the circuit is reduced. Embodiment 2 An embodiment of the present invention provides a method for reducing power consumption of a WIFI access point. As shown in FIG. 3, the execution entity of the method is a WIFI access point, and the station connection request sent by the WIFI access point receiving terminal is For example, the method includes: the following steps 201 to 204;
201、 WIFI接入点确定在预设时间内没有收到终端发送的 Station连 接请求, 通过执行步骤 201 , 可以确定出 WIFI接入点在预设时间范围内 没有收到终端发送的 Station连接请求,从而当确认没有 Station连接请求 后, 在预设时间范围以外的后续 Beacon帧周期内实施本发明节约功耗的 方法。 201. The WIFI access point determines that the station connection request sent by the terminal is not received within the preset time. After performing step 201, it may be determined that the WIFI access point does not receive the Station connection request sent by the terminal within a preset time range. Therefore, after confirming that there is no Station connection request, the method for saving power consumption of the present invention is implemented in a subsequent Beacon frame period outside the preset time range.
其中, 所述预设时间可以通过 Beacon帧周期的长度进行确定, 具体 的, 由于每个 Beacon帧周期的长度相同, 则所述预设时间可以为至少一 个 Beacon帧周期。 示例的, 若所述 WIFI接入点在两个 Beacon帧周期内 没有收到终端发送的 Station连接请求,则在两个 Beacon帧周期之后的后 续 Beacon帧周期内实施本发明节约功耗的方法。  The preset time may be determined by the length of the Beacon frame period. Specifically, the preset time may be at least one Beacon frame period because the length of each Beacon frame period is the same. For example, if the WIFI access point does not receive the Station connection request sent by the terminal within two Beacon frame periods, the power saving method of the present invention is implemented in the subsequent Beacon frame period after the two Beacon frame periods.
202、 WIFI接入点在当前 Beacon帧周期内, 在发送完 Beacon帧之 后执行第一功耗模式。 所述第一功耗模式包括所述 WIFI接入点中 WIFI IC和 WIFI IC的外围电路进行的正常工作模式。 本发明实施例中, 每个 Beacon帧周期为从开始发送当前 Beacon帧至下一次开始发送 Beacon帧 的时间间隔。  202. The WIFI access point performs the first power consumption mode after the Beacon frame is sent in the current Beacon frame period. The first power consumption mode includes a normal working mode performed by peripheral circuits of the WIFI IC and the WIFI IC in the WIFI access point. In the embodiment of the present invention, each Beacon frame period is a time interval from the start of sending the current Beacon frame to the next start of transmitting the Beacon frame.
203、 启动所述第一功耗模式的第一定时器。 203. Start a first timer of the first power consumption mode.
204、 判断在所述第一定时器的定时时间内是否收到终端发送的 Station接入请求, 在本发明实施例中, 如果在所述第一定时器的定时时 间内终端发送 Station 接入请求, 则执行步骤 209 ; 如果终端没有发送 Station接入请求, 则执行步骤 205。  In the embodiment of the present invention, if the terminal sends a station access request within the timing of the first timer, the terminal determines whether the station receives the station access request. Then, step 209 is performed; if the terminal does not send the station access request, step 205 is performed.
205、 判断所述 WIFI接入点是否进入下一个 Beacon帧周期。 在实现 205 步骤的过程中, WIFI 接入点判断其是否进入下一个 Beacon帧周期, 具体可以通过以下两种实现方式完成: 实现方式一 205. Determine whether the WIFI access point enters a next Beacon frame period. In the process of implementing step 205, the WIFI access point determines whether it enters the next Beacon frame period, which can be implemented in the following two implementation manners:
步骤 1 :在当前 Beacon帧周期内,设置第一预定数目 N个功耗模式, 所述预定数目 N 个功耗模式包括所述第一功耗模式和所述第二功耗模 式, 并且所述第一功耗模式的数目比所述第二功耗模式的数目多 1 ; 步骤 2: 判断当前所执行的功耗模式是否为第 N个功耗模式; 如果当前所执行的功耗模式为第 N个功耗模式, 则所述第 N个功耗 模式结束后即进入下一个 Beacon帧周期; 如果当前所执行的功耗模式不 为第 N个功耗模式, 则没有进入下一个 Beacon帧周期。 示例的, 可以通过设置计数器来判断当前所执行的功耗模式是否为 第 N个功耗模式。 假设初始时计数器大小为 0 , 在执行所述第一功耗模 式或所述第二功耗模式时, 计数器累加 1 , 并判断当前计数器的大小是否 小于或小于等于 N。由于所述 WIFI接入点在发送完 Beacon的当前 Beacon 帧周期内, 若没有收到终端发送的 Station接入请求, 会循环执行所述第 一功耗模式和所述第二功耗模式, 且首先执行所述第一功耗模式, 因此, 可以通过设置计数器的累积值来判断当前所执行的功耗模式是否为第 N 个功耗模式。 实现方式二 根据 Beacon帧周期定时器判断是否进入下一个 Beacon帧周期。 如果 Beacon帧周期定时器超时, 则进入下一个 Beacon帧周期; 如 果 Beacon帧周期定时器没有超时, 则没有进入下一个 Beacon帧周期。 具体的, 由于每个 Beacon帧周期的长度相同, 则可以设定一个定时 器来判断是否进入下一个 Beacon帧周期,该定时器的时长为一个 Beacon 帧周期的长度; 若 Beacon帧周期定时器超时, 则进入下一个 Beacon帧 周期, 若 Beacon帧周期定时器没有超时, 则没有进入下一个 Beacon帧 周期。 Step 1: In a current Beacon frame period, setting a first predetermined number N of power consumption modes, where the predetermined number N of power consumption modes includes the first power consumption mode and the second power consumption mode And the number of the first power consumption modes is one more than the number of the second power consumption modes; Step 2: determining whether the currently executed power consumption mode is the Nth power consumption mode; if currently performed If the power consumption mode is the Nth power consumption mode, the next Beacon frame period is entered after the Nth power consumption mode ends; if the currently executed power consumption mode is not the Nth power consumption mode, then no entry is made. The next Beacon frame period. For example, the counter can be set to determine whether the currently executed power mode is the Nth power mode. Assuming that the initial counter size is 0, when the first power consumption mode or the second power consumption mode is executed, the counter accumulates 1 and determines whether the current counter size is less than or less than or equal to N. The first power consumption mode and the second power consumption mode are cyclically executed if the WIFI access point does not receive the Station access request sent by the terminal within the current Beacon frame period of the Beacon. The first power consumption mode is first executed, and therefore, it is possible to determine whether the currently executed power consumption mode is the Nth power consumption mode by setting the accumulated value of the counter. The second implementation mode determines whether to enter the next Beacon frame period according to the Beacon frame period timer. If the Beacon frame period timer expires, the next Beacon frame period is entered. If the Beacon frame period timer does not expire, the next Beacon frame period is not entered. Specifically, because the length of each Beacon frame period is the same, a timer can be set to determine whether to enter the next Beacon frame period, and the duration of the timer is the length of a Beacon frame period; if the Beacon frame period timer expires Then, the next Beacon frame period is entered. If the Beacon frame period timer does not expire, the next Beacon frame period is not entered.
