Optionally, in step S22, according to first instruction information between the first communication mode and the second communication mode into Row switching may include step performed below:

Step S220 is determined according to the first instruction information and not stored on the second communication apparatus be sent to the first communication and set Standby downlink data；

Step S221, the first communication part of control enter dormant state, and control the second communication part and enter wake-up states, So that the first communication apparatus is in the second communication mode.

Downlink data due to that will be sent to STATION can be buffered in AP in advance, when not stored in AP Have the STATION it is data cached when, can be arranged in beacon frame represent it is data cached not in the presence of the STATION TIM mark.TIM uses bitmap (Bitmap) structure, to indicate whether be cached on AP and the associated each STATION of the AP Downlink data.Each STATION checks the flag value in Bitmap on corresponding position by the Tim field in beacon frame To determine whether be cached with corresponding downlink data on AP.

Table 1 is to indicate whether the optional example for being cached with the downlink data for being sent to STATION using Bitmap in TIM, such as Shown in table 1:

Table 1

STATION NO.	Beacon	Bitmap
			STATION 1	TIM flag 1	0
STATION 2	TIM flag 2	1
			STATION 3	TIM flag 3	1
STATION 4	TIM flag 4	0
			……	……	……
STATION n-1	TIM flag n-1	1
			STATION n	TIM flag n	0

Bitmap in TIM usually can be set to the matrix (M be positive integer with N) of M row × N column.Each TIM Flag respectively corresponds different STATION.It is exemplified by Table 1, the TIM flag of Tim field in the corresponding beacon frame of STATION 1 The TIM flag 2 of Tim field, STATION3 correspond to Tim field in beacon frame in 1, STATION 2 corresponding beacon frame TIM flag 3 ... and so on, until STATION n corresponds to the TIM flag n of Tim field in beacon frame.If TIM The value of flag is 1, then it represents that the corresponding downlink data of the STATION is cached on AP；If the value of TIM flag is 0, Then indicating uncached on AP has the corresponding downlink data of the STATION.It is uncached on AP when being determined according to the value of TIM flag When having the corresponding downlink data of the STATION, control WiFi component enters dormant state, and controls BLE component and enter wake-up shape State, so that STATION is in BLE operating mode.Such as: when determining on AP uncached there is this according to the value 0 of TIM flag 1 When the corresponding downlink data of STATION1, STATION 1 will control WiFi component and enter dormant state, and control BLE component Into wake-up states, so that STATION 1 is in BLE operating mode.

Still as shown in table 1, the corresponding lower line number of the STATION is cached on AP when determining according to the value of TIM flag According to when, control WiFi component stays awake for, and controls BLE component and enters dormant state, so that STATION is in WiFi work Operation mode.Such as: when according to the 2 corresponding downlink data of STATION is cached on the determining AP of the value 1 of TIM flag 2, STATION 2 will control WiFi component and stay awake for, and controls BLE component and enter dormant state, so that STATION 2 In WiFi operating mode.

Optionally, it in step S22, is carried out between the first communication mode and the second communication mode according to the first instruction information Can also include step performed below after switching:

Step S23 sends the first empty data frame to the second communication apparatus, wherein carry second in the first empty data frame Indicate that information, second indication information are identified as the first numerical value, the first numerical value is used to indicate the first communication part and is in wake-up shape State；

Step S24 receives the downlink data from the second communication apparatus by the first communication part；

Step S25 executes corresponding control according to downlink data and operates.

Empty data (Nulldata) frame is responsible for the power down mode change information of STATION being transmitted to AP.STA (is equivalent to Second indication information) be a field in Nulldata frame, for by the power down mode change notification of STATION to AP.Table 2 It is as shown in table 2 for the optional example changed using the power down mode of STA instruction STATION:

Table 2

STATION NO.	Nulldata No.	STA
			STATION 1	Nulldata 1	0- indicates work
STATION 2	Nulldata 2	1- indicates suspend mode
			STATION 3	Nulldata 3	1
STATION 4	Nulldata 4	0
			……	……	……
STATION n-1	Nulldata n-1	1
			STATION n	Nulldata n	0

By taking STATION 1 as an example, firstly, STATION 1 sends Nulldata 1 to AP, wherein the Nulldata1 is carried STA field value be 0, indicate STATION 1 be in WiFi operating mode.Secondly, STATION1 is connect by WiFi component Receive the downlink data from AP.Then STATION 1 executes corresponding control according to downlink data and operates.Below in conjunction with more A application scenarios execute corresponding control operation according to downlink data to STATION 1 and are illustrated:
