Abstract:
A call management method for a multi-subscriber identity module (SIM) multi-active terminal, where multiple user cards register with a centralized call management module of the multi-SIM multi-active terminal. The method includes, when a first user card is used for making a call or receiving a call, determining call statuses of the multiple user cards according to a connection list in the centralized call management module, where the connection list is used to record connection data of the multiple user cards; and when a second user card is in a conversation state, setting the first user card to a waiting state; or setting the first user card to a conversation state, and setting the second user card to a waiting state; or simultaneously setting the first user card and the second user card to a conversation state, to implement a conference call.
Abstract:
A harmonic suppression system, including an interface connector is connected to a common end of a first differential SPMT switch; a control port of the first differential SPMT switch is connected to a control port of a second differential SPMT switch, and a gating throw end of the first differential SPMT switch is separately connected to one end of each LC trap network in a one-to-one correspondence; the control port of the second differential SPMT switch is connected to a baseband chip, each gating throw end of the second differential SPMT switch is separately connected to the other end of each LC trap network in a one-to-one correspondence, and a common end of the second differential SPMT switch is connected to the baseband chip; the baseband chip is connected to an antenna switch; and the antenna switch is connected to a antenna.
Abstract:
A method includes detecting that an icon, on a desktop of a terminal device, of an application is associated with a share button; a storage location, of an installation file of the application, in the terminal device is determined; the installation file, to which the storage location points, of the application is sent, according to the storage location, of the installation file of the application, in the terminal device, to a terminal device with which the installation file needs to be shared; and therefore, a storage location, of an installation file of an application, in the terminal device can be automatically located by operating an icon of the application, and a user does not need to manually operate a file management tool to search for an installation file of a to-be-shared application.
Abstract:
A wireless communications device is provided. A first antenna and a second antenna are disposed on the wireless communications device, where an electrical length of the first antenna is N times an electrical length of the second antenna, where N is an integer greater than or equal to 1. The first antenna and the second antenna are disposed on a printed circuit board by means of common ground connection, that is, ground points of the first antenna and the second antenna are a same ground point, which reduces input impedance at the ground point of the first antenna and the second antenna, so that energy fed from the antennas is evenly distributed in a horizontal direction and a vertical direction of the printed circuit board.
Abstract:
A terminal device and a locking or unlocking method for the terminal device are provided. The locking or unlocking method is used for locking or unlocking a virtual key area of a terminal device when a touch panel of the terminal device is in an unlocked state, and the method includes: receiving multiple reported virtual key press events; and determining that the received virtual key press events meet a preset locking or unlocking condition, and setting a state of the virtual key area of the terminal device to a locked state or the unlocked state.
Abstract:
A call method of a terminal and a terminal using the call method, are provided to adjust voice quality of a call in real time. The method includes analyzing a spectral component of a voice signal during a call and selecting a corresponding frequency response channel according to an analysis result of the spectral component of the voice signal.
