To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

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

Examples of the wireless access device may include, but are not limited to, a Mobile hotspot (Mobile WIFI, hereinafter abbreviated as MIFI) device, which is a portable wireless network extension device and integrates functions of a modem, a router, and hotspot access. According to some embodiments of the present application, as shown in fig. 1, the MIFI device 10 may be inserted with a SIM (subscriber identity Module) card to access wireless signals from the mobile communication base station 30 through a built-in modem, and provide a wireless network hotspot in a power-free scenario, so that a plurality of devices 20 (e.g., the

devices

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

Examples of device 20 may include, but are not limited to, WIFI-enabled cell phones, computers, tablets, multimedia players, and the like, according to some embodiments of the present application. In some embodiments, the device 20 may also include a device that does not support WIFI functionality, such as a computer without WIFI functionality, in which 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 typically uses a battery as a power supply source, and the duration of the device is an important aspect that affects the user experience.

Generally, in the case of no data traffic, the modem of the MIFI 10 may switch from a connected state to an idle state to reduce power consumption. In Idle state, the modem periodically listens to the paging channel for paging messages, i.e. Idle DRX (Discontinuous Reception), and when it needs to send or receive data, it will first switch to connected state. Due to the existence of DRX, the modem is awakened periodically, for example, in LTE (Long Term Evolution), the DRX cycle is generally 1.28s, the duration of each wake-up process is about 50ms, and the wake-up power consumption is about 100 mA. Therefore, the modem is an important factor influencing the endurance time of the MIFI equipment.

According to the scheme provided by the application, the modems are dynamically managed, the modems gradually enter different deep sleep states under the standby condition of products, the power consumption of the modems under the standby scene is reduced, and therefore the endurance time of the MIFI is prolonged.

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

According to some embodiments of the present Application, as shown in fig. 2, an Application Processor (AP) 100 and a modem 200 may be included in the MIFI device 10. The application processor 100 may be coupled to the modem 200 and control the operation of the modem 200, and in various embodiments, the application processor 100 and the modem 200 may be integrated or may be separate modules.

The application processor 100 may include one or more AP cores to control 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 subscriber identity module 102, a network status monitoring module 103, a USB module 104, and a sleep control module 105. In some embodiments, the modules described above 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 may be configured to monitor an access status of a WIFI user, for example, may be configured to monitor that several devices currently access to WIFI, identify information of the devices accessing to WIFI, and the like.

The subscriber identity module 102 may be used to identify subscriber information, for example, according to some embodiments of the present application, the subscriber identity module may be a SIM card detection module, which is used to detect whether a SIM card is in place and to query the account opening status of the SIM card subscriber. Alternatively, in some embodiments, the MIFI device may have an eSIM integrated therein, in which case the subscriber identity module 102 may not need to detect whether the SIM card is in place, but may still be used to query the user for the account opening status.

The network status monitoring module 103 may be configured to perform a query of a network registration status. According to some embodiments of the present application, the network status monitoring module 103 may determine whether the currently-camped network supports only PS (packet switched) domain services or both PS and CS (Circuit switched) domain services by querying a network registration status. Generally, the CS domain service mainly relates to voice and short message services, because voice services usually require exclusive circuit path resources on a communication network, and different users need to provide circuit switching functions to connect the exclusive circuit path resources with each other to enable a conversation. PS domain services mainly relate to data services, such as streaming media services, Voice Over Internet Phone (VOIP) services, and the like, packet switching is to divide user data into messages (i.e., packets) with a certain length for transmission and switching, and a header is added to the front of each packet, where the header mainly contains address information to indicate where the packet is sent, and then the packet can be forwarded to a destination by a switch according to the address information of each packet.

The hardware interface monitoring module 104 may be used to identify whether the current hardware interface is connected to another device. 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 may connect to a computing device such as a computer through USB, cause the computing device to surf the internet through the MIFI device via USB, or, in some embodiments, connect to a power adapter through USB for charging, etc.

The sleep control module 104 may be configured to control an operating 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 a standby scenario. For example, according to some embodiments of the present application, the sleep control module 104 may determine whether the device 10 is in an idle state according to a connection state of the device, start a timing device and listen for a wake-up request if the device 10 is in the idle state, and control the MIFI device 10 to enter different sleep states according to a duration of the no wake-up state if the device 10 is not awake all the time.

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

According to some embodiments of the present application, the hibernation state of the MIFI device 10 may be classified, and as the hibernation level increases, the power consumption of the MIFI device 10 decreases step by step, and meanwhile, the duration for the device to return to the normal operating state also increases step by step.

According to some embodiments of the present application, the sleep control module 104 may 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 WIFI module 101 has no user access and device 10 has no USB connection, the system may be considered to be in an idle state.

According to some embodiments of the present application, the sleep control module 105 may start a timing mechanism and listen for a wake-up request while the device is in an idle state. In this state, the MIFI device 10 is in a no data traffic state, and the modem 200 switches 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 does not perceive, at this time, the power consumption of the device 10 is still in a higher level (lower than a normal operating state), and the modem 200 may periodically listen to a paging message (IdleDRX) of a paging channel, and in this state, the user may wake up the device 10 by accessing the WIFI, so that the MIFI device 10 returns to the normal operating state. According to some embodiments of the present application, this state may be considered a zero-order sleep state.

If the state without awakening lasts for a certain time, the device can be controlled to enter the next-stage dormancy. According to some embodiments of the present application, sleep control module 105 may control device 10 to enter a primary sleep state without waking up after a first time threshold (e.g., 10 minutes) has elapsed. Sleep control module 105 may turn off the WIFI broadcast and send an instruction to modem 200 to decrease the modem's CPU frequency. The modem 200 receives an instruction to decrease the CPU frequency of the modem through the communication module 201, and decreases the CPU frequency of the modem 200 through the CPU frequency modulation module 202 according to the received instruction to decrease the CPU frequency of the modem, for example, the CPU frequency may be adjusted to a lowest frequency, that is, a lowest value of the CPU operating frequency. Generally, the operating frequency of the CPU is determined by hardware, different CPUs have different operating frequency ranges, and the power consumption of the CPU can be effectively reduced by adjusting the frequency of the CPU to the lowest value of the operating frequency.

In a state where the CPU frequency of the modem is the lowest frequency, the CPU of the modem 200 is in an idle state at the lowest frequency, thereby reducing power consumption of the modem 200 due to DRX wake-up. Meanwhile, when the WIFI broadcast is turned off, the user cannot search for the WIFI Service Set Identifier (SSID) of the MIFI device 10, and therefore cannot wake up the MIFI device 10 in a WIFI access manner, and needs to wake up the device through other wake-up sources. According to some embodiments of the present application, the other wake-up source may include a power key, a USB interface, and the like, for example, the application processor 100 may monitor a switch module, a hardware interface, or a charging module of the device in real time, and wake up the MIFI device when it is monitored that the power key is pressed, another device is connected to the MIFI device 10 through the hardware interface, and charging is started, and the like, so as to restore the device to a normal operating state. In some other embodiments, other wake-up modes may be provided. In the first-order sleep state, the power consumption of the device 10 is approximately at a medium level (lower than the zero-order sleep state).

According to some embodiments of the present application, after entering the primary hibernation state, if the always-on-no-wake state continues for a duration that the MIFI device is in the primary hibernation state is greater than a second time threshold (e.g., 5 minutes), the hibernation control module 105 may control the device 10 to enter the secondary hibernation state. The sleep control module 105 may send an instruction to the modem 200 to turn off the diversity antenna, informing the modem 200 to turn off the diversity antenna, and only keep the main set antenna operating, thereby reducing power consumption generated by the diversity antenna operating in case of a loss of a portion of reception performance. In some embodiments, multiple diversity antennas may be included in device 10, in which case a secondary sleep state may be entered by turning off all diversity antennas, or only a portion of the diversity antennas may 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, only the main set antenna is kept working, and the CPU frequency of the modem 200 is still at the lowest frequency. The WIFI is turned off, the user cannot search the WIFI SSID, the device cannot be awakened through a WIFI access mode, and the device needs to be awakened through other awakening sources, for example, the above-mentioned modes of pressing a power key, inserting a USB, charging and the like are adopted. 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 power consumption caused by DRX wake-up. In the secondary sleep state, the device power consumption is approximately at a low level (lower than the primary sleep state).

According to some embodiments of the present application, the operation of the hibernation control module 105 in the two-stage hibernation state may also be variously adjusted as long as the staged hibernation of the MIFI device is implemented. For example, sleep control module 105 may send instructions to modem 200 to turn off the diversity antenna when control device 10 enters a primary sleep state, and send down instructions to modem 200 to control modem 200 to reduce the CPU frequency of modem 200 via CPU frequency tuning module 202 when control device 10 enters a secondary sleep state. For another example, when the sleep control module 105 controls the device 10 to enter the primary sleep state, it may perform only any one of operations of turning off the WIFI broadcast, sending an instruction to the modem 200 to decrease the CPU frequency of the modem, and/or sending an instruction to the modem 200 to control the modem to turn off the diversity antenna, and then perform at least one of the remaining operations when entering the secondary sleep state.

Under the premise that the MIFI equipment does not support CS domain services, in a scene without data services, the fact that DRX awakening exists is not very significant, and power consumption generated by DRX awakening is reduced on the contrary. Therefore, according to some embodiments of the present application, in case the device 10 does not support CS domain traffic, the DRX wake-up may be turned off directly, thereby further reducing the power consumption of the device 10.

According to some embodiments of the present application, if the currently camped network of the MIFI device 10 does not support CS domain traffic, the timing may continue to be performed by the timing device, and in the case that the device 10 is still not awake for a third time threshold (e.g., 5 minutes) after the time in the secondary sleep state, the sleep control module 105 may control the device 10 to enter the tertiary sleep state, and interrupt all communication functions of the wireless access device. Sleep control module 105 may send an instruction to modem 200 to turn off the main set antenna, causing modem 200 to enter an airplane mode. According to some embodiments of the present application, if the currently residing network of the MIFI device 10 supports CS domain traffic, 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 command, enters the flight mode, and the modem 200 is in the completely disconnected state. Meanwhile, when the WIFI is turned off, the user cannot search the WIFI SSID, the device cannot wake up through the WIFI access mode, and the device needs to wake up through other wake-up sources, for example, the above-mentioned modes of pressing a power key, inserting a USB, charging, and the like. At this time, the modem 200 does not periodically listen to the paging message of the paging channel any more, thereby avoiding the modem 200 from being awakened by IDLE DRX and completely saving power consumption caused by DRX awakening. In the three-level sleep state, the device power consumption is at a lowest level (lower than the two-level sleep state).

In some embodiments, device 10 may only have a primary set of antennas and no diversity antennas, in which case sleep control module 105 may control device 10 to enter the tertiary sleep state directly from the primary sleep state without waking up at all times, or may skip the secondary sleep state directly in order to reduce the hierarchy of sleep states for device 10. That is, after controlling device 10 to turn off WIFI and/or reduce the operating frequency of the CPU of the modem, device 10 may be directly controlled to turn off all antennas after a period of time, so that device 10 enters the flight mode. That is, it may be determined whether the time that the device 10 is in the primary sleep state is greater than a fourth time threshold (for example, 8 minutes) while the device 10 is in the primary sleep state, and in a case where it is determined that the time that the device 10 is in the primary sleep state is greater than the fourth time threshold, the device 10 is directly placed in a state in which both the WIFI broadcast 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 may determine whether the current residing network of the wireless access device supports CS domain services such as voice or short message according to information obtained in the subscriber identity module 102 and/or the network status detection module 103. For example, whether the current residing network of the wireless access device supports CS domain services such as voice or short message may be determined by integrating the SIM card information and the network registration status.

The functional blocks of the device 10 described above with reference to fig. 2 are only examples, and in various embodiments, the MIFI device 10 may include more or less blocks than those shown in fig. 2, some blocks may be combined arbitrarily to be integrated into one block, some blocks may be split into more discrete blocks, and so on.

Various embodiments of the present application are described above by taking an MIFI device as an example, but the various embodiments of the present application may be applied to not only an MIFI device but also various other wireless access devices having requirements on power consumption. According to the embodiment of the application, the modem 200 of the device is controlled differently along with the increase of the sleeping time, so that the power consumption of the modem 200 in a standby scene is reduced, meanwhile, the power consumption is reduced step by utilizing the sleeping states of different levels, and the user experience is guaranteed.

A sleep control method according to an embodiment of the present application is described below with reference to fig. 3.

According to some embodiments of the application, the hibernation state of the device can be classified, the power consumption of the device is gradually reduced along with the improvement of the hibernation level, meanwhile, the duration of the device recovering to a normal working state is also gradually increased, and in some embodiments, the device can be an MIFI device or other devices with a WIFI access function.

First, at block S101, according to some embodiments of the present application, an access state of WIFI of a current device and a connection state of a hardware interface are detected, and whether a WIFI user accesses the current device or whether another device is connected to the current device through the hardware interface is checked, in some embodiments, the hardware interface may be, for example, a USB interface.

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 may be considered to be in an idle state.

In case the device is in an idle state (yes judgment in block S102), according to some embodiments of the present application, block S103 may start a timing device and listen for a wake-up request at any time. In this state, the current device is in a state without data traffic, and the modem in the device switches from a connected state to an idle state to reduce power consumption. At this time, the WIFI of the current device is in an accessible state, the modem is in an idle state, and in this state, the user does not perceive, at this time, the power consumption of the current device is still in a higher level (lower than a normal operating state), and the device still periodically listens to a paging message (IdleDRX) of a paging channel, and in this state, the user can wake up the device by accessing the WIFI, so that the device returns to a normal operating state. According to some embodiments of the present application, this state may be considered a zero-order sleep state.

According to some embodiments of the present application, if the state of no wake-up continues for a certain time, the device may be controlled to enter the next stage of sleep. At block S104, it is determined whether the duration of the no-wake state exceeds a first time threshold, which may be, for example, 10 minutes. In the case that the first time threshold is exceeded, block S105 may be continued, where the current device is controlled to enter a primary sleep state, the WIFI broadcast is turned off, and the CPU frequency of the modem of the device is reduced, for example, the frequency of the CPU may be adjusted to a lowest frequency, that is, a lowest value of the CPU operating frequency.

When the CPU frequency of the modem is the lowest frequency, the CPU of the modem of the device is in an idle state with the lowest frequency, thereby reducing the power consumption of the modem caused by DRX awakening. Meanwhile, the WIFI broadcast is turned off, and the user cannot search for the WIFI Service Set Identifier (SSID) of the current device, so that the current device cannot be woken up in a WIFI access manner, and the device needs to be woken up by other wake-up sources. According to some embodiments of the present application, the other wake-up source may include a power key, a USB interface, and the like, for example, a switch module, a hardware interface, or a charging module of the current device may be monitored in real time, and when it is monitored that the power key is pressed, another device is connected to the current device through the hardware interface, and starts charging, and the like, the current device is woken up to restore the device to a normal operating state. In some other embodiments, other wake-up modes may be provided. In the first-order sleep state, the power consumption of the current device is approximately at a middle level (lower than the zero-order sleep state).

According to some embodiments of the present application, after entering the primary hibernation state, if the state of no wake-up continues, the method may continue to block S106, and determine whether the time that the MIFI device is in the primary hibernation state exceeds a second time threshold, where the second time threshold may be, for example, 5 minutes. If the second time threshold is exceeded, the process may continue to block S107, where the current device is controlled to enter a secondary sleep state, the diversity antenna of the current device is turned off, only the main set antenna is kept operating, and power consumption generated by the operation of the diversity antenna is reduced in the case of a loss of a part of reception performance. In some embodiments, multiple diversity antennas may be included in the current device, in which case a secondary sleep state may be entered by turning off all diversity antennas, or only a portion of the diversity antennas may be turned off.

In the secondary sleep state, the device only keeps the primary set antenna working while the CPU frequency of the device's modem is still at the lowest frequency. The WIFI is turned off, the user cannot search the WIFI SSID, the device cannot be awakened through a WIFI access mode, and the device needs to be awakened through other awakening sources, for example, the above-mentioned modes of pressing a power key, inserting a USB, charging and the like are adopted. At this time, the modem of the current device still periodically listens to the paging message (Idle DRX) of the paging channel, but since the CPU of the modem operates at the lowest frequency, a part of the power consumption caused by DRX wake-up can be reduced. In the secondary sleep state, the device power consumption is approximately at a low level (lower than the primary sleep state).

According to some embodiments of the present application, the operations of blocks S105 and S107 may also be variously adjusted as long as the hierarchical hibernation of the MIFI device is implemented. For example, in block S105, upon entering the primary sleep state, an operation of turning off a diversity antenna of the device may be performed, and in block S107, upon entering the secondary sleep state, an operation of lowering a CPU frequency of a modem of the device may be performed. For another example, when the primary sleep state is entered in block S105, only one of operations such as turning off the WIFI broadcast, lowering the CPU frequency of the modem, and/or turning off the diversity antenna may be performed, and when the secondary sleep state is entered in block S107, at least one of the remaining operations may be performed.

According to some embodiments of the present application, the current device may not support CS domain services, e.g., an MIFI device without voice call and short message functions. On the premise that the CS domain service is not supported, in a scene without data service, the meaning of existence of DRX wakeup is not very large, and the power consumption generated by DRX wakeup is reduced on the contrary. Therefore, according to some embodiments of the present application, in a case that the current device does not support CS domain traffic, the DRX wakeup may be directly turned off, thereby further reducing power consumption of the current device.

According to some embodiments of the present application, block S108, it is determined whether the current device supports CS domain services. According to some embodiments of the present application, it may be determined whether a current residing network of the wireless access device supports CS domain services such as voice or short message by integrating SIM card information and a network registration state.

If the currently residing network of the current device does not support CS domain services (i.e., no determination in block S108), timing may continue by the timing device, and it may be determined whether the time that the current device is in the secondary sleep state exceeds a third time threshold (block S110), which may be, for example, 5 minutes. If the third time threshold is exceeded, the method may continue to block S111, where the current device is controlled to enter a three-level sleep state, the main set antenna of the current device is turned off, all communications of the wireless access device are interrupted, and the flight mode is entered.

Under the three-level sleep state, the current equipment enters a flight mode and is in a complete network disconnection state. Meanwhile, when the WIFI is turned off, the user cannot search the WIFI SSID, the device cannot wake up through the WIFI access mode, and the device needs to wake up through other wake-up sources, for example, the above-mentioned modes of pressing a power key, inserting a USB, charging, and the like. At this time, the modem of the device does not periodically listen to the paging message of the paging channel any more, thereby avoiding the modem from being awakened by IDLE DRX and completely saving the power consumption generated by DRX awakening. In the three-level sleep state, the device power consumption is at a lowest level (lower than the two-level sleep state).

In some embodiments, the current device may only have a primary set of antennas and no diversity antennas, in which case the primary sleep state may be entered directly into the tertiary sleep state without waking up all the time, or the secondary sleep state may be skipped directly in order to reduce the hierarchy of the sleep states of the device. That is, after the WIFI is turned off and/or the operating frequency of the CPU of the modem is lowered, all antennas may be directly turned off after a period of time, so that the device enters the flight mode. That is, it may be determined whether the time that the current device is in the primary sleep state is greater than a fourth time threshold (for example, 8 minutes) when the current device is in the primary sleep state, and in a case where it is determined that the time that the current device is in the primary sleep state is greater than the fourth time threshold, the current device may be directly placed in a state where both the WIFI broadcast function and the antenna are turned off, and the operating frequency of the CPU of the modem is the lowest.

If the determination in block S108 is yes, that is, the currently-residing network of the current device supports the CS domain service, the process continues to block S109, so that the device stays in the secondary sleep state, and listens for the wake-up request in the secondary sleep state.

In the timing process, the device may monitor the wake-up source at any time, and when a wake-up request is received, for example, when it is detected that the power key is pressed, other devices are connected to the current device through the hardware interface, and charging is started, etc., the device may be restored to a normal operating state (block S112).

According to the embodiment of the application, different adjustments are performed on the current equipment along with the increase of the sleeping time length, the power consumption of the equipment in a standby scene is reduced, meanwhile, the power consumption is reduced step by utilizing the sleeping states of different levels, and the user experience is guaranteed.
