Fig. 1 is a schematic diagram of an application scenario of a wireless access device according to an embodiment of the present application.

Examples of wireless access devices may include, but are not limited to, mobile hotspot (Mobile WIFI, hereinafter referred to as MIFI) devices. The MIFI device is a portable wireless network extension device that integrates the functions of a modem, a router, and hotspot access. According to some embodiments of the present application, as shown in FIG. 1, a SIM card (Subscriber Identification Module, subscriber identification card) is inserted into the MIFI device 10 to access the wireless signal from the mobile communication base station 30 through the built-in modem. A wireless network hotspot is provided in a power-free scenario, so that multiple devices 20 (for example, the

devices

20a, 20b, and 20c shown in FIG. 1) can share a network connection. In some embodiments, the MIFI device 10 may also have an embedded SIM card (Embedded-SIM, hereinafter referred to as eSIM).

According to some embodiments of the present application, examples of the device 20 may include, but are not limited to, mobile phones, computers, tablets, multimedia players, etc. that support WIFI function. In some embodiments, the device 20 may also include a device that does not support WIFI function, such as a computer without WIFI function. In this case, the device 20 and the MIFI device 10 may be connected by a wired connection, so that the device 20 can Access the Internet through the MIFI device 10.

The MiFi device 10 usually uses a battery as a power source, and the battery life of the device is an important aspect that affects the user experience.

Generally, when there is no data service, the modem of MIFI 10 will switch from the connected state to the idle state to reduce power consumption. In the idle state, the modem will periodically listen for paging messages on the paging channel, that is, Idle DRX (Discontinuous Reception), and will first switch to the connected state when it needs to send or receive data. Due to the existence of DRX, the modem will be periodically woken up. For example, in LTE (Long Term Evolution), the DRX cycle is generally 1.28s, the duration of each wake-up processing is about 50ms, and the wake-up power consumption is about 100mA. Therefore, the modem is an important factor affecting the battery life of MIFI equipment.

The solution provided by this application enables the modem to gradually enter different deep sleep states when the product is in standby mode through dynamic management of the modem, thereby reducing the power consumption of the modem in the standby scenario, thereby increasing the MIFI battery life.

FIG. 2 shows an example of the architecture of the sleep control system of the MIFI device 10 according to an embodiment of the present application.

According to some embodiments of the present application, as shown in FIG. 2, the MIFI device 10 may include an application processor (Application Processor, hereinafter referred to as AP) 100 and a modem 200. The application processor 100 may be coupled with the modem 200 and control the operation of the modem 200. In different embodiments, the application processor 100 and the modem 200 may be integrated together, or may be two separate modules.

The application processor 100 may include one or more AP cores for controlling various operations of the MIFI device 10. According to some embodiments of the present application, the application processor 100 may include a WIFI module 101, a user identification module 102, a network status monitoring module 103, a USB module 104, and a sleep control module 105. In some embodiments, the above-mentioned modules may be integrated in the AP core of the application processor 100.

According to some embodiments of the present application, the WIFI module 101 in the application processor 100 can be used to monitor the access status of WIFI users. For example, it can be used to monitor how many devices are currently connected to WIFI and identify the devices that are connected to WIFI. Information and so on.

The user identification module 102 may be used to identify user information. For example, according to some embodiments of the present application, the user identification module may be a SIM card detection module for detecting whether the SIM card is in place and querying the account opening status of the SIM card user. Or, in some implementations, the MIFI device may be integrated with an eSIM. In this case, the subscriber identification module 102 may not need to detect whether the SIM card is in place, but it can still be used to query the user's account opening status.

The network status monitoring module 103 can be used to query the network registration status. According to some embodiments of the present application, the network status monitoring module 103 can determine whether the current resident network only supports PS (Packet Switch) domain services or supports both PS domain services and CS (Circuit Switch) by querying the network registration status. Circuit switching) domain business. Usually, CS domain services mainly involve voice and short message services, because voice services usually require exclusive circuit path resources on the communication network. To be able to talk between different users, the communication network needs to provide circuit switching functions, which will mutually exclusive circuits. Channel resources are connected to each other. PS domain services mainly involve data services, such as streaming media services, Voice over Internet Phone (VOIP) services, etc. Packet switching is to divide user data into packets (ie, packets) of a certain length. For transmission and exchange, a header is added in front of each packet. The header mainly contains address information to indicate where the packet is sent. Then the switch can forward the packet to the destination according to the address information of each packet.

The hardware interface monitoring module 104 can be used to identify whether the current hardware interface is connected to other devices. According to some embodiments of the present application, the hardware interface may include, but is not limited to, a Universal Serial Bus (USB) interface. For example, in some embodiments, the MIFI device can be connected to a computing device such as a computer via USB, so that the computing device can access the Internet via the MIFI device via USB, or, in some embodiments, the MIFI device can be charged by connecting a power adapter via USB. Wait.

The sleep control module 105 can be used to control the working state of the modem 200 in the MIFI device 10, so that the device 10 gradually enters different sleep states, thereby reducing power consumption in standby scenarios. For example, according to some embodiments of the present application, the sleep control module 105 can determine whether the device 10 is in the idle state according to the connection state of the device. When the device 10 is in the idle state, it starts the timing device and monitors the wake-up request. In the case of, the MIFI device 10 is controlled to enter different sleep states according to the duration of the non-wake-up state.

The modem 200 can be used to send, receive and process signals. According to some embodiments of the present application, it can include a communication module 201, a CPU frequency modulation module 202, and an antenna control module 203. The communication module 201 in the modem 200 can be used to implement the communication between the modem 200 and the sleep control module 105 in the AP core, and the CPU frequency modulation module 202 can be used to adjust the CPU frequency of the modem 200, and the antenna control module 203 can be used to control The operation of the main antenna and the diversity antenna of the modem 200.

According to some embodiments of the present application, the sleep state of the MIFI device 10 can be graded. As the sleep level increases, the power consumption of the MIFI device 10 is gradually reduced, and the time for the device to return to the normal working state is also gradually increased.

According to some embodiments of the present application, the sleep control module 105 can determine whether the device is in an idle state according to the WIFI access state obtained from the WIFI module 101 and the hardware connection state obtained from the hardware interface monitoring module 104. For example, if the WIFI module 101 has no user access and the device 10 has no USB connection, it can be considered that the system is in an idle state.

According to some embodiments of the present application, when the device is in an idle state, the sleep control module 105 can activate the timing device and monitor the wake-up request. In this state, the MIFI device 10 is in a state without data services, and the modem 200 will switch from the connected state to the idle state to reduce power consumption. At this time, the WIFI of the MIFI device 10 is in an accessible state, and the modem 200 is in an idle state. In this state, the user has no perception. At this time, the power consumption of the device 10 is still at a higher level (lower than the normal working state), and the modem 200 The paging message (Idle DRX) of the paging channel is periodically listened to. In this state, the user can wake up the device 10 by accessing WIFI, and restore the MIFI device 10 to a normal working state. According to some embodiments of the present application, this state may be considered as a zero-level sleep state.

If there is no awakening state for a certain period of time, the device can be controlled to enter the next level of sleep. According to some embodiments of the present application, the sleep control module 105 can control the device 10 to enter the first-level sleep state in the case that there is no wake-up after a first time threshold (for example, 10 minutes). The hibernation control module 105 can turn off the WIFI broadcast and send an instruction to the modem 200 to reduce the CPU frequency of the modem. The modem 200 receives an instruction to reduce the CPU frequency of the modem through the communication module 201, and reduces the CPU frequency of the modem 200 through the CPU frequency modulation module 202 according to the received instruction to reduce the CPU frequency of the modem. For example, the frequency of the CPU can be adjusted to the lowest Frequency, that is, the lowest value of the CPU operating frequency. Generally speaking, the operating frequency of the CPU is determined by the hardware. Different CPUs have different operating frequency ranges. By adjusting the frequency of the CPU to the lowest value of the operating frequency, the power consumption of the CPU can be effectively reduced.

When the CPU frequency of the modem is at the lowest frequency, the CPU of the modem 200 is in an idle state at the lowest frequency, thereby reducing the power consumption of the modem 200 due to DRX wakeup. At the same time, the WIFI broadcast is turned off, and the user cannot search for the WIFI service set identifier (SSID) of the MIFI device 10. Therefore, the MIFI device 10 cannot be awakened through the WIFI access mode, and the device needs to be awakened by other wake-up sources. According to some embodiments of the present application, other wake-up sources may include a power button, a USB interface, etc., for example, the application processor 100 may monitor the switch module, hardware interface, or charging module of the device in real time, and when it detects that the power button is pressed, When other devices connect to the MIFI device 10 through the hardware interface, and start charging, etc., the MIFI device is awakened to restore the device to a normal working state. In some other embodiments, other wake-up methods can also be set. In the first-level sleep state, the power consumption of the device 10 is approximately at a medium level (lower than the zero-level sleep state).

According to some embodiments of the present application, after entering the first-level sleep state, if the state that has not been awakened continues and the MIFI device is in the first-level sleep state for longer than the second time threshold (for example, 5 minutes), then the sleep control module 105 The device 10 can be controlled to enter the secondary sleep state. The sleep control module 105 can send an instruction to turn off the diversity antenna to the modem 200 to notify the modem 200 to turn off the diversity antenna and only keep the main antenna working, so as to reduce the power consumption of the diversity antenna when a part of the receiving performance is lost. In some embodiments, the device 10 may include multiple diversity antennas. In this case, all the diversity antennas can be turned off to enter the secondary sleep state, or only a part of the diversity antennas can be turned off.

In the secondary sleep state, the modem 200 turns off the diversity antenna through the antenna control module 203 according to the received instruction, leaving only the main antenna to work, and the CPU frequency of the modem 200 is still at the lowest frequency. The WIFI is off, the user cannot find the WIFI SSID, and the device cannot be woken up through WIFI access. It needs to wake up the device through other wake-up sources, such as pressing the power button, plugging in the USB, charging, etc. as mentioned above. At this time, the modem 200 still periodically listens to the paging message (Idle DRX) of the paging channel, but the CPU of the modem 200 operates at the lowest frequency, which can reduce a part of the power consumption caused by DRX wakeup. In the second-level sleep state, the power consumption of the device is probably at a low level (lower than the first-level sleep state).

According to some embodiments of the present application, the operation of the sleep control module 105 in the above-mentioned two-level sleep state can also be adjusted in various ways, as long as the hierarchical sleep of the MIFI device is realized. For example, the sleep control module 105 can send an instruction to the modem 200 to control the diversity antenna to turn off when the control device 10 enters the first-level sleep state, and when the control device 10 enters the second-level sleep state, send a frequency reduction instruction to the modem 200 to control the modem. 200 reduces the CPU frequency of the modem 200 through the CPU frequency modulation module 202. For another example, when the sleep control module 105 controls the device 10 to enter the first-level sleep state, it can only perform the operation of turning off the WIFI broadcast, sending an instruction to the modem 200 to reduce the modem's CPU frequency, and/or sending an instruction to the modem 200 to control its shutdown Any one of the operations such as the operation of the diversity antenna, and at least one of the remaining operations is performed when entering the second-level sleep state.

In most cases, MIFI devices do not support CS domain services. Under this premise, in scenarios where there is no data service, in fact, the significance of DRX wake-up is not great, but the power consumption generated by DRX wake-up reduces the product. Long battery life. Therefore, according to some embodiments of the present application, when the device 10 does not support CS domain services, the DRX wakeup can be directly turned off, thereby further reducing the power consumption of the device 10.

According to some embodiments of the present application, if the current resident network of the MIFI device 10 does not support CS domain services, it can continue to be timed by the timing device, and the time when the device 10 is in the secondary sleep state passes the third time threshold (for example, 5 minutes). ) When there is still no awakening, the sleep control module 105 can control the device 10 to enter a three-level sleep state and interrupt all communication functions of the wireless access device. The sleep control module 105 may send an instruction to turn off the main antenna to the modem 200 to make the modem 200 enter the flight mode. According to some embodiments of the present application, if the current resident network of the MIFI device 10 supports CS domain services, the control device 10 remains in the secondary sleep state.

In the three-level sleep state, the modem 200 cuts off all communications according to the received instruction, enters the flight mode, and the modem 200 is in a completely disconnected state. At the same time, the WIFI is turned off, the user cannot find the WIFI SSID, and the device cannot be woken up through WIFI access. It needs to wake up the device through other wake-up sources, such as pressing the power button, plugging in the USB, charging, etc. as mentioned above. At this time, the modem 200 no longer periodically listens to the paging message of the paging channel, so as to prevent the modem 200 from being awakened by IDLE and DRX, and completely save the power consumption caused by the DRX wakeup. In the third-level sleep state, the power consumption of the device is at the lowest level (lower than the second-level sleep state).

In some embodiments, the device 10 may only have a main antenna but no diversity antenna. In this case, the sleep control module 105 can control the device 10 to enter the third-level sleep state directly from the first-level sleep state without waking up. Or, in order to reduce the grading of the sleep state of the device 10, the secondary sleep state can also be skipped directly. That is, after the control device 10 turns off the WIFI and/or reduces the operating frequency of the modem's CPU, after a period of time, the device 10 can be directly controlled to turn off all antennas, so that the device 10 enters the flight mode. That is, when the device 10 is in the first-level sleep state, it can be determined whether the time that the device 10 is in the first-level sleep state is greater than the fourth time threshold (for example, 8 minutes), and when it is determined that the time that the device 10 is in the first-level sleep state is greater than the fourth time threshold. In the case of the time threshold, the device 10 is directly placed in a state where both the WIFI broadcasting function and the antenna are turned off, and the operating frequency of the CPU of the modem 200 is the lowest.

According to some embodiments of the present application, the dormancy control module 105 can determine whether the current resident network of the wireless access device supports CS such as voice or SMS based on the information obtained from the user identification module 102 and/or the network status detection module 103. Domain business. For example, it is possible to judge whether the current resident network of the wireless access device supports CS domain services such as voice or short message by integrating the SIM card information and the network registration status.

The functional modules in the device 10 described above in conjunction with FIG. 2 are merely examples. In various implementations, the MIFI device 10 may include more or fewer modules than those shown in FIG. 2, and some modules may be combined arbitrarily. So as to integrate into one module, some modules can also be split into more discrete modules and so on.

The MIFI device is used as an example to introduce various implementation manners of the present application. However, the various implementation manners of the present application may not only be used for MIFI devices, but also applicable to various other wireless access devices that require power consumption. The embodiment of the present application reduces the power consumption of the modem 200 in the standby scenario by performing different controls on the modem 200 of the device as the sleep duration increases, and at the same time, uses different levels of sleep states to achieve a gradual reduction in power consumption. Ensure user experience.

The following describes the sleep control method according to the embodiment of the present application in conjunction with FIG. 3.

According to some embodiments of the present application, the sleep state of the device can be classified. As the sleep level increases, the power consumption of the device is gradually reduced, and the time for the device to return to the normal working state is also gradually increased. In some embodiments, , The device can be a MIFI device or other devices with WIFI access function.

First, block S101, according to some embodiments of the present application, detect the WIFI access status of the current device and the connection status of the hardware interface, check whether the current device has WIFI user access, or whether there are other devices connected to the current device through the hardware interface In some embodiments, the hardware interface may be, for example, a USB interface.

In block S102, it is determined whether the device is in an idle state according to the detection result of block S101. For example, if the current device has no WIFI user access and no USB connection, the system can be considered to be in an idle state.

In the case that the device is in an idle state (Yes in block S102), according to some embodiments of the present application, block S103, the timing device can be activated and the wake-up request can be monitored at any time. In this state, the current device is in a state without data services, and the modem in the device will switch from the connected state to the idle state to reduce power consumption. At this time, the WIFI of the current device is in an accessible state, and the modem is in an idle state. In this state, the user has no perception. At this time, the power consumption of the current device is still at a high level (lower than the normal working state), and the device will still Periodically listen for paging messages (Idle DRX) of the paging channel. In this state, the user can wake up the device by accessing WIFI and restore the device to a normal working state. According to some embodiments of the present application, this state may be considered as a zero-level sleep state.

According to some embodiments of the present application, if the state of no awakening continues for a certain period of time, the device can be controlled to enter the next level of sleep. In block S104, it is determined whether the duration of the non-awakening state exceeds a first time threshold. The first time threshold may be, for example, 10 minutes. In the case of exceeding the first time threshold, you can continue to block S105, control the current device to enter the first-level sleep state, turn off WIFI broadcasting, and reduce the CPU frequency of the device’s modem. For example, the CPU frequency can be adjusted to the lowest frequency. , That is, the lowest value of the CPU operating frequency.

When the modem's CPU frequency is at the lowest frequency, the device's modem CPU is in the idle state at the lowest frequency, thereby reducing the power consumption of the modem due to DRX wakeup. At the same time, the WIFI broadcast is turned off, and the user cannot search for the WIFI service set identifier (SSID) of the current device. Therefore, the current device cannot be awakened through WIFI access, and the device needs to be awakened by other wake-up sources. According to some embodiments of the present application, other wake-up sources can include the power button, USB interface, etc., for example, the switch module, hardware interface, or charging module of the current device can be monitored in real time. When the power button is monitored, other devices pass through. When the hardware interface connects to the current device and starts charging, etc., it wakes up the current device and restores the device to a normal working state. In some other embodiments, other wake-up methods can also be set. In the first-level sleep state, the current power consumption of the device is probably at a medium level (lower than the zero-level sleep state).

According to some embodiments of the present application, after entering the first-level sleep state, if the state without awakening continues, it can continue to block S106 to determine whether the MIFI device is in the first-level sleep state for more than the second time threshold. The time threshold may be, for example, 5 minutes. In the case of exceeding the second time threshold, you can continue to block S107, control the current device to enter the second-level sleep state, turn off the diversity antenna of the current device, and only keep the main antenna to work, and reduce the diversity antenna work if a part of the receiving performance is lost The resulting power consumption. In some implementation manners, the current device may include multiple diversity antennas. In this case, all the diversity antennas can be turned off to enter the secondary sleep state, or only a part of the diversity antennas can also be turned off.

In the secondary sleep state, the device only keeps the main antenna to work, and the CPU frequency of the device's modem is still at the lowest frequency. The WIFI is off, the user cannot find the WIFI SSID, and the device cannot be woken up through WIFI access. It needs to wake up the device through other wake-up sources, such as pressing the power button, plugging in the USB, charging, etc. as mentioned above. At this time, the modem of the current device still periodically listens to the paging message (Idle DRX) of the paging channel, but because the CPU of the modem works at the lowest frequency, a part of the power consumption caused by DRX wake-up can be reduced. In the second-level sleep state, the power consumption of the device is probably at a low level (lower than the first-level sleep state).

According to some embodiments of the present application, the operations of block S105 and block S107 can also be adjusted in various ways, as long as the hierarchical sleep of the MIFI device is realized. For example, in block S105, when entering the first-level sleep state, the operation of turning off the diversity antenna of the device may be performed, and in block S107, when entering the second-level sleep state, the operation of reducing the CPU frequency of the device's modem may be performed. For another example, in block S105, when entering the first-level sleep state, only any one of the operations such as turning off WIFI broadcasting, reducing the CPU frequency of the modem, and/or turning off the diversity antenna can be performed. And when entering the second-level sleep state in block S107, at least one of the remaining operations is performed.

According to some embodiments of the present application, the current device may not support CS domain services, for example, MIFI devices without voice call and short message functions. Under the premise that CS domain services are not supported, in a data-free service scenario, in fact, DRX wake-up does not have much significance, and the power consumption generated by DRX wake-up reduces the product life time. Therefore, according to some embodiments of the present application, when the current device does not support the CS domain service, the DRX wakeup can be directly turned off, thereby further reducing the power consumption of the current device.

According to some embodiments of the present application, in block S108, it is determined whether the current device supports CS domain services. According to some embodiments of the present application, it is possible to determine whether the current resident network of the wireless access device supports CS domain services such as voice or short message by integrating the SIM card information and the network registration status.

If the current resident network of the current device does not support the CS domain service (that is, the determination in block S108 is no), the timing device can be used to continue timing, and it is determined whether the current device is in the secondary sleep state for a time exceeding the third time threshold (block S110 ), the third time threshold may be, for example, 5 minutes. When the third time threshold is exceeded, it can continue to block S111, control the current device to enter a three-level sleep state, turn off the main antenna of the current device, interrupt all communications of the wireless access device, and enter the flight mode.

In the three-level sleep state, the current device enters the airplane mode and is in a completely disconnected state. At the same time, the WIFI is turned off, the user cannot find the WIFI SSID, and the device cannot be woken up through WIFI access. It needs to wake up the device through other wake-up sources, such as pressing the power button, plugging in the USB, charging, etc. as mentioned above. At this time, the modem of the device no longer periodically listens to the paging message of the paging channel to prevent the modem from being awakened by IDLE DRX, and completely save the power consumption caused by DRX wake-up. In the third-level sleep state, the power consumption of the device is at the lowest level (lower than the second-level sleep state).

In some implementations, the current device may only have a main antenna but no diversity antenna. In this case, the first-level sleep state can be directly entered into the third-level sleep state when there is no wake-up, or to reduce the number of devices. For the classification of the sleep state, the second level sleep state can also be skipped directly. That is, after turning off the WIFI and/or reducing the operating frequency of the modem's CPU, after a period of time, all antennas can be directly turned off to make the device enter the flight mode. That is, when the current device is in the first-level sleep state, it can be determined whether the time that the current device is in the first-level sleep state is greater than the fourth time threshold (for example, 8 minutes), and when it is determined that the current device is in the first-level sleep state, the time is greater than the fourth time threshold. In the case of the time threshold, the current device is directly placed in a state where the WIFI broadcast function and antenna are turned off, and the operating frequency of the modem's CPU is the lowest.

If the determination in block S108 is yes, that is, the current resident network of the current device supports CS domain services, then proceed to block S109 to keep the device in the second-level sleep state, and monitor the wake-up request in the second-level sleep state.

During the timing process, the device can monitor the wake-up source at any time. When a wake-up request is received, for example, it detects that the power button is pressed, other devices connect to the current device through the hardware interface, and start charging, etc., it will return to the normal working state. (Block S112).
