Abstract: Embodiments of the present invention relate to the field of communications technologies, and disclose a call termination method, an application processor, and a modem. In this solution, the application processor receives a hang-up instruction and sends a first message to the modem according to the hang-up instruction, where the first message is used to trigger the modem to directly terminate a call. The modem may terminate the call in a timely manner according to the first message. Therefore, a time consumed in call termination is reduced and efficiency is improved.

Abstract: The present disclosure provides a data transmission method and a terminal. The method includes respectively allocating, by a terminal, a first download range and a second download range to a first network interface card and a second network interface card according to an obtained download range of to-be-downloaded data; and if the terminal determines that when a preset download time arrives, the first network interface card completes downloading of the first download range and the second network interface card does not complete downloading of the second download range, performing, by the terminal, a first allocation operation at least once. This reduces download duration of to-be-downloaded data.

Abstract: A wireless communications component that supports a first radio access technology (RAT) and a second RAT. After the wireless communications component establishes a connection with a second RAT network, the wireless communications component receives a first message sent by the second RAT network. The first message includes content that is used to query a second RAT capability of the wireless communications component. The wireless communications component sends a second message to the second RAT network. The second message is used to indicate the second RAT capability of the wireless communications component and indicate that the wireless communications component does not support the first RAT. Because the wireless communications component reports to the second RAT network that the wireless communications component does not support the first RAT, the second RAT network does not instruct the wireless communications component to be changed to the first RAT.
