Description
Technical Field
The invention relates to the field of communication, in particular to a dormancy method and device of wireless fidelity Wi-Fi equipment.
Background
With the development of science and technology, people have more and more demands on internet surfing, and Wi-Fi equipment with a Wi-Fi function is produced at the same time. Wi-Fi equipment has various types, and a Union Wireless-Fidelity (Ufi) product and a Wireless Fidelity (Wi-Fi) hotspot in the Ufi product are taken as examples for explanation, wherein the Wi-Fi hotspot in the Ufi product is an important function, the dormancy strategy of the hotspot is more rigid, and the actual effect or the user experience is not good; for Wi-Fi hotspots in mobile phone products, the functions are simple, the settable functions are few, and the hotspot dormancy strategy is hardly set.
In the related art, for the dormancy policy of hot spots, the existing methods in the terminal (e.g., mobile phone) products on the wifi and the market are as follows: setting a timer, presenting an interface for a user to select the time of the timer, wherein the options of sleeping after 5 minutes, sleeping after 10 minutes and never sleeping are generally provided, then the system counts time, and if the current hotspot is not connected by user clients and no data line is inserted after the time is up, the Wi-Fi hotspot is completely closed (unloading the drive and powering off the chip), and then the system can enter the sleeping state to achieve the purpose of saving power.
Therefore, in the related art, when no other terminal is connected with the Wi-Fi hotspot and the Wi-Fi device is not charged, the Wi-Fi function in the Wi-Fi device is turned off after the sleep time arrives, so that if the other terminal wants to search for connection with the Wi-Fi hotspot later, the Wi-Fi hotspot cannot be searched at all, and the Wi-Fi device can only be woken up manually to wait for starting Wi-Fi again, thereby reducing user experience; and before the sleep time is not reached, the Wi-Fi function in the Wi-Fi device is always in an on state, but if connection and data transmission do not exist, the on of the Wi-Fi function is meaningless, a large amount of electric quantity in the terminal is consumed, and the electric quantity cannot be effectively saved. Therefore, after the Wi-Fi equipment is dormant, other terminals cannot detect the opened Wi-Fi hotspot in the dormant Wi-Fi equipment, and therefore the other terminals cannot access a wireless network provided by the Wi-Fi equipment.
Aiming at the problem that other terminals cannot access a wireless network provided by Wi-Fi equipment after the Wi-Fi equipment is dormant in the related technology, an effective solution is not provided at present.

And a switching unit 62, configured to switch the Wi-Fi device from an operating state to a low-power-consumption sleep state by using a voltage switch and a clock switch, where the voltage switch is used to adjust a voltage of the Wi-Fi device, and the clock switch is used to adjust a clock frequency of the Wi-Fi device.
The Wi-Fi equipment can be a smart phone, a tablet and other intelligent terminals. The power consumption standby of the intelligent terminal is an important problem all the time, and on one hand, the problem can be solved by adopting a large-capacity battery; on the other hand, from the perspective of software, measures can be taken to optimize system power consumption; as is known, the Wi-Fi function is popularized in intelligent devices, and compared with a traditional bluetooth local area network, the Wi-Fi function has significantly increased power consumption, and a power saving strategy of the Wi-Fi function also becomes a hot issue; at present, when Wi-Fi is in a Station (Station, abbreviated as STA) mode, a plurality of power saving strategies exist, but an effective power saving strategy is still not seen in a hotspot mode, which may depend on the product type, and a wireless router serving as a hotspot function generally has an external power supply; however, as the application of the hotspot function is more and more applied to mobile phones and wifi products, the power saving of the hotspot function needs to be considered in a key way, and the products are often not powered by an external power supply;
the access of other terminals to the wireless network provided by the Wi-Fi device is substantially the access of other terminals to the Wi-Fi hotspot of the Wi-Fi device. The hibernation of a Wi-Fi device may also be understood as the hibernation of a Wi-Fi hotspot in a Wi-Fi device. In the related technology, the sleep mode of the Wi-Fi hotspot in the Wi-Fi equipment can completely close the Wi-Fi function, so that other terminals cannot search the hotspot when wanting to connect to the Wi-Fi hotspot, and only can manually wake up the Wi-Fi equipment which opens the Wi-Fi hotspot to restart the Wi-Fi hotspot, thereby causing low user experience; in addition, before the Wi-Fi device is in a sleep state, the opened Wi-Fi hotspot is always in a normal open state, so that the power cannot be saved. When no data is transmitted, the Wi-Fi chip is in a low power consumption state, only the low power and low clock of the chip are provided to maintain the most basic function, meanwhile, the bus can enter a sleep state to enable the system to enter the sleep state, when data exists, the Wi-Fi chip provides a wake-up signal to the system to wake up the system, and the bus and the Wi-Fi chip are further woken up to carry out normal work; such an implementation ensures that Wi-Fi functionality is optimized for power saving while in the on state.
The embodiment of the invention also provides an intelligent sleep strategy of the Wi-Fi hotspot function, which can not only meet the requirement that the hotspot is in an open state for a long time, but also achieve the purpose of saving power, and overcomes the defect that the prior sleep strategy needs user intervention, so that the problem that in the related technology, Wi-Fi equipment needs to try to sleep when effective data does not exist for a long time, and needs to intervene by a user to wake up the system, the bus and the Wi-Fi equipment to normally work when effective interactive data exists is solved.

the bus controller module 74 is a module directly connected to the Wi-Fi chip 76, and is configured to send data to the Wi-Fi chip 76 or receive data to an upper layer; here, an interrupt of the register remote wake-up function is mainly realized;
the Wi-Fi chip 76 belongs to Wi-Fi hardware, the chip can wake up a signal line at a far end, and when an interrupt signal is sent when data exists, the power management module 712 is informed to wake up Wi-Fi equipment so as to wake up a Wi-Fi function;
