Abstract: A method includes: A first device performs device discovery when detecting a preset trigger signal acting on to-be-shared data. The first device establishes physical links with n discovered second devices, where Wi-Fi direct connection functions of the first device and the n second devices are enabled. The first device sends the to-be-shared data to a target device when detecting a selection signal of the target device, where the target device is one of the n second devices. According to embodiments of this application, the first device performs device discovery when detecting the preset trigger signal acting on the to-be-shared data, and establishes the physical links with the n discovered second devices before the target device is selected for data transmission.

Abstract: A network performance improvement method and an apparatus for user equipment. In the network performance improvement method, user equipment establishes a first PDN connection and transmits data of a first application program through the first PDN connection. Then, the user equipment starts a second application program and determines whether a current network status satisfies a quality of service requirement of the second application program. When determining that the current network status does not satisfy the quality of service requirement of the second application program, the user equipment starts to establish a second PDN connection, and transmits, after the second PDN connection is successfully established, at least a part of application data of the second application program through the second PDN connection.

Abstract: In an antitheft method for a mobile terminal that relates to the field of communications technologies, a baseband processor detects integrity of an operating system running on an application processor, generates a short message service (SMS) message when the operating system has no integrity, and transfers the SMS message to the application processor. The application processor controls a display to display the SMS message in order to inform a user that the operating system of the mobile terminal is damaged. In a scenario in which a mobile terminal is stolen and an operating system is maliciously tampered with, according to the solution provided in this application, an SMS message is used to prompt a user, thereby improving security of the mobile terminal.
