A wireless communication device (100) comprises a first transceiver (110) comprising a first frequency synthesizer (112) which comprises a first digitally controlled oscillator (DCO1) and a crystal oscillator (XO). The wireless communication device (100) further comprises a second transceiver (120) comprising a wakeup receiver (Rx2), a second transmitter (Tx2) and a second digitally controlled oscillator (DCO2) connected to the wakeup receiver (Rx2) and second transmitter (Tx2). The wireless communication 10 device (100) further comprises a control unit (170) configured to control operation of the wireless communication device. The second transmitter (Tx2) is configured to transmit periodically a signal to a base station. The signal is modulated by a code identifying the wireless communication device (100) and transmitted at a frequency set by the second digitally controlled oscillator (DCO2).

A motor vibration control method and an electronic device can implement vibration of a motor when a loading capability of a battery is low. A battery status is obtained when a first motor vibration waveform vibration request is received. The battery status includes a battery temperature, a battery temperature and a battery level, or a battery power supply capability. A motor vibration parameter is switched if the battery status meets a preset condition, where the preset condition is that the battery power supply capability is lower than a first threshold, the battery temperature is lower than a second threshold, or the battery temperature and the battery level are lower than a third threshold array. The motor vibration parameter includes a motor vibration waveform or a motor vibration input voltage. The motor is driven to vibrate based on a switched motor vibration parameter.

Apparatus and methods related to acquiring service on mobile computing devices (MCDs) are provided. A method includes determining a decreasing sequence of scan ratios, each scan ratio indicating a proportion of time over which a MCD scans one or more frequencies to attempt connection with a wireless network during a disconnected time window. The method further includes determining a connected time window' when the MCD is connected to the wireless network. The method additionally includes determining a ping-pong rate for the MCD based at least on a duration of the connected time window. The method also includes selecting a scan ratio from the decreasing sequence of scan ratios based on the ping-pong rate. The method further includes scanning the one or more frequencies in accordance with the decreasing sequence of scan ratios and starting from the selected scan ratio to cause the MCD to attempt connection with the wireless network.

A method of predicting a remaining battery life in a device is provided. The method includes obtaining battery state information indicative of a current state of a charge of a battery, the battery being configured to supply power to a device; predicting, by using a machine learning algorithm, a remaining battery life of the device on which a specific application is to be executed, based on the obtained battery state information; and providing, to a user, an indication of the predicted remaining battery life.

The present disclosure generally relates to methods and user interfaces for establishing communications.

A system includes an electronic device and an auxiliary device for charging the electronic device and facilitating hardware shutdown/reset of the electronic device when the electronic device is being charged. The system includes an input user interface (e.g., on the auxiliary device or the electronic device) configured to receive a user input for hardware shutdown/reset of the electronic device. The electronic device includes a switch between a battery and a system load, a control circuit configured to open the switch to disconnect the battery and the system load, and a charging interface configured to receive electric power signals from the auxiliary device to power the control circuit, such that hardware shutdown/reset of the electronic device is performed when the electronic device is being charged, thereby preventing unintentional hardware shutdown/reset during normal use. In some embodiments, wireless control signals are used to initiate hardware shutdown/reset on the electronic device.

This application discloses a display control method and an apparatus. The method is applied to a mobile terminal, the mobile terminal includes a display, the mobile terminal is connected to an external device, and the method includes: when the mobile terminal is on a voice call by using the external device, determining that the mobile terminal is in a handheld state or a non-handheld state; and when the mobile terminal is in the handheld state, controlling the display to be in a screen-on state; or when the mobile terminal is in the non-handheld state, controlling the display to be in a screen-off state. When the mobile terminal is on the voice call by using the external device, a display control solution is intelligently selected by determining that the mobile terminal is in the handheld state or the non-handheld state.

Systems and methods of deferring a transmission of a message are provided. In one exemplary embodiment, a method by a wireless device (105, 200, 300a-b, 600) comprises determining (1001) whether a timer (106, 205) associated with deferring a transmission (107) of a message (113) on a certain uplink or downlink logical channel is configured and not running for that certain uplink or downlink logical channel. Further, the method includes transmitting (1011), to a network node (101), the message on that certain uplink or downlink logical channel responsive to determining that the timer is configured and not running for that certain uplink or downlink logical channel.

A method for controlling the activity of a base station entity of a first type in a mobile communication network via a mobile device having a communication link to a base station entity of a second type includes: sending, by the mobile device, a connection request to the base station entity of the second type, the connection request being related to a request of the mobile device to have a communication link with the base station entity of the first type while the base station entity of the first type is in its second operational mode; and activating the first operational mode of the base station entity of the first type and establishing the communication link between the mobile device and the base station entity of the first type established.
