POWER CONSUMPTION CONTROL METHOD FOR WEARABLE DEVICE, AND WEARABLE DEVICE

TECHNICAL FIELD

The present invention relates to the field of communications technologies, and in particular, to a power consumption control method for a wearable device, and a wearable device.

BACKGROUND

A wearable device is a generic name for devices that are wearable and that are developed by applying a wearable technology to intelligent design for daily wear, such as smart glasses, smart gloves, smart watches, smart clothing, or smart shoes. Among the devices, a smart watch and a smart band are most notable. In addition, with the rapid development of a smart wearable device, a function of the wearable device becomes increasingly stronger. At the same time when the function develops, power consumption also increases quickly for the wearable device, especially for a wearable device with a wireless data communication function. Because power consumption of a wireless network functional module, which is in a static standby state, in the wearable device is relatively high, a standby time of the wearable device is reduced. In addition, because a size of the wearable device is limited, it is impossible to improve a battery life of a product by unlimitedly increasing a battery capacity. Therefore, an energy-saving technology becomes a key technology direction for the development of the wearable device.

However, in the prior art, there is no corresponding technical solution for how to prolong the standby time of the wearable device (that is, a battery life of the wearable device). Therefore, how to reduce the power consumption of the wearable device to prolong the standby time of the wearable device currently becomes a technical problem to be urgently resolved.

DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

A terminal involved in the embodiments of the present invention may include but is not limited to a mobile phone, a mobile computer, a tablet computer, a personal digital assistant (Personal Digital Assistant, PDA), a media player, and the like, or may include a device such as an automatic teller machine (Automatic Teller Machine, ATM for short). The embodiments of the present invention do not limit a form of the terminal.

A wearable device involved in the embodiments of the present invention may be a device such as a smart band, smart glasses, smart gloves, a smart watch, smart clothing, or smart shoes, where the device can be worn by a user, can process a corresponding service of the user, and can perform intelligent interaction with the user. The wearable device in the embodiments may include a modem that is used to perform remote wireless communication with a wireless network. For example, the modem may perform remote wireless communication with network-side a base station, mobility management entity, or the like, that is, receive and process content of a remote wireless communication service. The wearable device may further include a service processor that processes service data of the wearable device. The service data may include local data of the wearable device (for example, data collected by the wearable device, such as a body temperature and a heartbeat), may further include the content, obtained by the modem, of the remote wireless communication service, and may further include service data of near field communication that is obtained through short range communications, such as Bluetooth or Wireless Fidelity (Wireless-Fidelity, WiFi for short). Optionally, the modem and the service processor each may be an independent chip, or may be integrated in a processor chip. The embodiments of the present invention do not limit physical implementation forms of the modem and the service processor. Optionally, the modem may be a modem processor that can perform 2G, or 3G, or 4G wireless communication, and the service processor may integrate a function of WiFi, Bluetooth, or WiFi and Bluetooth.

A method involved in the embodiments of the present invention is aimed at resolving a prior-art technical problem that power consumption of a wearable device cannot be effectively reduced, and as a result, a standby time of the wearable device is short. It should be noted that the mentioned standby time of the wearable device in the embodiments of the present invention refers to a battery life of the wearable device.

The following describes in detail the technical solutions of the present invention by using specific embodiments. The following several specific embodiments may be combined with each other. Details of a same or similar concept or process may not be described in an embodiment.

FIG. 1 is a schematic flowchart of Embodiment 1 of a power consumption control method for a wearable device according to the present invention. This embodiment relates to a specific process in which a wearable device implement reduction of power consumption of the wearable device according to a status of a modem. As shown in FIG. 1, the method includes:

S101: When a modem of a wearable device is in an off state, the wearable device receives remote wireless communication service information transmitted by a terminal through short range communications, where the remote wireless communication service information includes a prompt message of a remote wireless communication service or content of a remote wireless communication service, and the prompt message of the remote wireless communication service is used to prompt a user to determine whether to turn on the modem.

S102: When a modem of a wearable device is in an on state, the wearable device receives content, sent by a network device, of the remote wireless communication service.

It should be noted that, in this embodiment, S101 and S102 are an overall technical characteristic and describe an overall working state of the wearable device at different circumstances, and therefore there is no limitation on a time sequence relationship between S101 and S102.

Specifically, in this embodiment, when the modem of the wearable device is in the off state, there is a communication connection between the wearable device and the terminal. Optionally, the wearable device may establish the communication connection with the terminal in advance and then deactivate the modem; or the wearable device may deactivate the modem and establish the communication connection with the terminal simultaneously. The foregoing communication connection between the wearable device and the terminal may be a near field communication connection (or a short range communications connection), for example, a near field communication connection established, by using the terminal as a WiFi hotspot, by the wearable device with the terminal by using a WiFi function; or a near field communication connection established by the wearable device with the terminal by means of Bluetooth pairing; or a near field communication connection established by the wearable device with the terminal by using a Zigbee protocol. In conclusion, the wearable device can establish the communication connection with the terminal by using any one of near field communication technologies, and transparent transmission of a data service can be implemented between the wearable device and the terminal. The foregoing manner of short range communications may be a Bluetooth communication manner, may be a WiFi or NFC communication manner, or may be another near field communication manner.

When the modem of the wearable device is in the off state, the terminal may detect a status of the modem of the wearable device, or the wearable device notifies the terminal of a current status of the modem through the short range communications. After the terminal learns that the modem of the wearable device is in the off state, the terminal may notify the network device to send, to the terminal, the content that is of the remote wireless communication service and that should be originally sent to the wearable device. Alternatively, when the modem of the wearable device is not turned off, the wearable device notifies the network device to send, to the terminal, the content that is of the remote wireless communication service and that should be originally sent to the wearable device.

After receiving the content of the remote wireless communication service, the terminal transmits the remote wireless communication service information to the wearable device through the short range communications, where the remote wireless communication service information includes the content of the remote wireless communication service or the prompt message of the remote wireless communication service, and the prompt message of the remote wireless communication service is used to prompt the user to determine whether to turn on the modem and is used to notify the wearable device of content, currently received by the terminal, of the remote wireless communication service. The user may select to turn on the modem so that the content of the remote wireless communication service is processed on the wearable device, or the user may select not to turn on the modem so that the content of the remote wireless communication service is processed on the terminal.

In another aspect, in this embodiment, when the modem of the wearable device is in the on state, the modem may receive the content, sent by the network device, of the remote wireless communication service.

In the prior art, a modem of a wearable device is in a state of receiving content, sent by a network device, of a remote wireless communication service in real time for a long time, that is, the modem of the wearable device is in a standby state or a working state for a long time, and as a result, power consumption of the wearable device is very large, and a standby time of the wearable device is short. However, in this embodiment of the present invention, the wearable device may flexibly use, according to a status of the modem, a different manner of receiving the content of the remote wireless communication service. When the modem is in an off state, a manner of transparently transmitting remote wireless communication service information by using a terminal prevents the modem of the wearable device from always being in the state of receiving the content, sent by the network device, of the remote wireless communication service, that is, prevents the modem from always being in the standby state or the working state, thereby reducing the power consumption of the wearable device and prolonging the standby time of the wearable device.

According to the power consumption control method for a wearable device provided in this embodiment of the present invention, when a modem of a wearable device is in an off state, remote wireless communication service information transmitted by a terminal through short range communications is received. Alternatively, when a modem of a wearable device is in an on state, content, sent by a network device, of the remote wireless communication service is received. That is, the wearable device may flexibly use, according to a status of the modem, a different manner of receiving the content of the remote wireless communication service. When the modem is in the off state, a manner of transparently transmitting the remote wireless communication service information by using the terminal prevents the modem of the wearable device from always being in a state of receiving the content, sent by the network device, of the remote wireless communication service, that is, prevents the modem from always being in a standby state or a working state, thereby reducing power consumption of the wearable device and prolonging a standby time of the wearable device.

FIG. 2 is a schematic flowchart of Embodiment 2 of a power consumption control method for a wearable device according to the present invention. This embodiment relates to a specific process in which, when a modem of a wearable device is in an off state and when the foregoing remote wireless communication service information is a prompt message of a remote wireless communication service, the wearable device receives content of the remote wireless communication service. On the basis of the foregoing embodiment, further, as shown in FIG. 2, after the foregoing S101, the method includes the following steps:

S201: When the modem of the wearable device is in the off state, the wearable device activates the modem according to a selection instruction entered by the user, where the selection instruction is an instruction for selectively activating the modem that is entered by the user according to the prompt information of the remote wireless communication service.

Specifically, when the modem is in the off state, the wearable device receives the prompt message that is of the remote wireless communication service and that is transmitted by the terminal through the short range communications, where the prompt message is used to prompt the user to determine whether to turn on the modem and is used to notify the wearable device of content, currently received by the terminal, of the remote wireless communication service. According to the prompt message of the remote wireless communication service, the user may select to process the content of the remote wireless communication service on the wearable device, or select to process the content of the remote wireless communication service on the terminal. Optionally, the prompt message of the remote wireless communication service may be a message carrying an option control for the user to select. When the user selects to process the content of the remote wireless communication service on the wearable device, the user enters the selection instruction to the wearable device. Optionally, the selection instruction is related to an operation of the user. For example, it is assumed that the foregoing prompt message of the remote wireless communication service is a pop-up dialog box. Referring to a schematic diagram of a prompt message of a remote wireless communication service shown in FIG. 3, the dialog box includes two selection controls. After the user taps a different control, a different selection instruction is entered to the wearable device. When the user taps a control 1, a selection instruction that the user enters to the wearable device is used to instruct the wearable device to turn on the modem. FIG. 3 shows only an example. This embodiment of the present invention does not limit a form of the prompt message of the remote wireless communication service, as long as the user can make a selection.

S202: The wearable device processes, by using the modem, the received content of the remote wireless communication service.

Specifically, after the wearable device activates the modem, the wearable device may receive, by using the modem, the content, sent by a network device, of the remote wireless communication service, and may further process the content of the remote wireless communication service or process the content of the remote wireless communication service with a service processor inside the wearable device. Optionally, the content of the remote wireless communication service may be a wireless service such as an incoming call, a short message service message, or a multimedia messaging service message.

According to the power consumption control method for a wearable device provided in this embodiment of the present invention, when a modem of a wearable device is in an off state, a prompt message, received by the wearable device, of a remote wireless communication service is used to prompt a user to select a corresponding device (the wearable device or a terminal) to process content of the remote wireless communication service, so that the wearable device activates the modem according to a selection instruction of the user, and receives, by using the turned-on modem, the content, transmitted by the terminal, of the remote wireless communication service.
