摘要： This application provides a connection establishment method and a terminal device. The method includes: A terminal device first obtains historical data of an MPTCP connection established between the terminal device and an application server. Because the historical data includes a data transmission delay of a TCP connection corresponding to a Wi-Fi network and a data transmission delay of a TCP connection corresponding to a cellular network, the terminal device determines, based on the historical data, that the data transmission delay of the TCP connection corresponding to the cellular network is less than or equal to the data transmission delay of the TCP connection corresponding to the Wi-Fi network, and establishes the first TCP connection to the application server through an interface of the cellular network; and after the first TCP connection is successfully established, the terminal device establishes the second TCP connection to the application server through an interface of the Wi-Fi network.

摘要： This application provides a method for multiplexing HTTP channels and a terminal that relate to the field of communications technologies, and may implement multiplexing of HTTP channels between a terminal and a server, to improve data transmission efficiency between the terminal and the server. The method is applied to the terminal and includes: sending, by the terminal, a first HTTP request to a first server through a first HTTP channel, to request first data; after receiving a first HTTP response returned by the first server, receiving, through the first HTTP channel, a first part that is of the first data and that is sent by the first server; and if a size that is of the first data and that is carried in the first HTTP response is greater than a first threshold, generating a second HTTP request, and sending a second HTTP request to a second server through a second HTTP channel, to request a second part of the first data; and after receiving the first part of the first data, sending control signaling to the first server, to disconnect the first HTTP channel.

摘要： This application discloses an HTTP request transmission method and a device. The HTTP request transmission method and the device relate to the field of electronic devices, and resolve a problem that data finally obtained through splicing is invalid because dividing an original HTTP request into a plurality of HTTP requests to pull data from different CDN servers may cause inconsistency of the pulled data. When an electronic device needs to download data from a plurality of CDN servers, an overlapping range may be designed for byte ranges allocated to the different CDN servers. This means that the electronic device downloads data in the overlapping range from all the different CDN servers. Therefore, this part of data is used to check consistency of the data pulled from the different CDN servers. When determining that the data pulled from the different CDN servers is consistent, the electronic device may splice the data to obtain finally required data.

摘要： This application provides a touch method and an electronic device. The method relates to the fields such as foldable devices and human-computer interaction. The method may be applied to an electronic device configured with a foldable display. The display includes a first area, a second area, and a third area, and when the electronic device is in a folded form, an included angle between the first area and the third area is less than a first preset angle, and two sides of a second area are the first area and the third area. The method includes: displaying a first interface in the first area, where the first interface includes one or more touchable areas; determining a first touch area between a user and the second area; mapping a touch function of a first touchable area in the first interface to the first touch area; detecting a first operation in the first touch area; and controlling the first touchable area in the first interface based on the first operation. The method may control a primary screen and/or a secondary screen by performing an operation on a side screen.

摘要： This application relates to the field of mobile communications, and provides a voice call method, an electronic device, and a system, to resolve a problem that when an audio signal is transmitted through a voice link established between a mobile phone and a peripheral device by using a Bluetooth technology, a call requirement in a scenario in which a relatively large amount of data needs to be transmitted cannot be met. The voice call method may include: A mobile phone establishes a Bluetooth link to a notebook computer according to a Bluetooth protocol. The mobile phone receives call request information, and sends the call request information to the notebook computer through the Bluetooth link. The two electronic devices establish a Wi-Fi link according to a Wi-Fi protocol. The mobile phone receives an answer command sent by the notebook computer through the Bluetooth link, sends the answer command to a third electronic device, establishes a call with the third electronic device, receives a downlink audio signal, and sends the downlink audio signal to the notebook computer through the Wi-Fi link. In the foregoing technical solutions, the audio signal in the call is transmitted through the Wi-Fi link, so that quality and call efficiency of the call on the mobile phone are improved.

摘要： This application provides a multipath aggregation scheduling method and an electronic device. The method includes: when there are a plurality of paths between a client and a service end, configuring transmission sequences of network packets on different paths, to enable a network packet sent later on any path to be sent first on at least one path in other paths. In the multipath aggregation scheduling method provided in this application, a data transmission rate of a path does not need to be estimated, and degrees of freedom of a plurality of paths are fully utilized, thereby improving a data transmission rate and robustness in a multipath scenario.

摘要： Embodiments of this application provide a permission negotiation method and apparatus during communication, and an electronic device. In the foregoing permission negotiation method during communication, a first electronic device displays an interface of a currently running communication application; and after detecting a first operation of a user, obtains, in response to the first operation, a permission item restricted for use in a process of communication with a second electronic device. Then, the first electronic device sends a first request to the second electronic device, where the first request includes the permission item restricted for use; receives confirmation information of the second electronic device for the permission item restricted for use; and restricts, based on the confirmation information, a locally installed application on applying for the permission item restricted for use. Finally, after communication with the second electronic device ends, the first electronic device restores settings of the permission item of the locally installed application to settings that precede the communication with the second electronic device. In this way, before or during a call, two communication parties can negotiate the permission item restricted for use during communication.

摘要： This application provides a data transmission method and an electronic device. The method includes: establishing, by an electronic device, a multipath transmission control protocol MPTCP connection to a first application server, where the MPTCP connection includes a first TCP connection and a second TCP connection, and a data transmission delay of the first TCP connection is less than a data transmission delay of the second TCP connection; and receiving, by the electronic device, indication information from the first application server, where the indication information includes a type identifier used to indicate a type of a data stream sent by the first application server; when the type identifier is a first identifier, receiving, by the electronic device preferentially by using the first TCP connection, the data stream from the first application server in a first time period after the electronic device receives the indication information; or when the type identifier is a second identifier, receiving, by the electronic device preferentially by using the second TCP connection, the data stream in a second time period after the electronic device receives the indication information. This method is used to resolve a prior-art problem that costs are comparatively high because data transmission occupies comparatively large traffic of a wide area network and occupies comparatively small traffic of a local area network.
