Abstract: Disclosed are a hypertext transfer protocol (HTTP) request transmission method and device. The HTTP request transmission method and device 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 content distribution network (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.

Abstract: A connection establishment method includes a terminal device obtaining historical data of a multipath transmission control protocol (MPTCP) connection established between the terminal device and an application server. The historical data includes a data transmission delay of a transmission control protocol (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 a 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 a second TCP connection to the application server through an interface of the Wi-Fi network.

Abstract: This application provides a data transmission method. The method includes: An electronic device first establishes an MPTCP connection to an application server, where the MPTCP connection includes two TCP connections. Then, the electronic device receives indication information from an application server, where the indication information includes a type identifier and a parameter. When the type identifier indicates a low data transmission delay requirement, the electronic device receives, in a first time period after the electronic device receives the indication information, the data stream by using a first TCP connection. When an accumulated data amount actually received by the electronic device in the first time period is less than a product of the parameter and duration corresponding to the first time period, the electronic device receives the data stream in a second time period by using both the two TCP connections.

Abstract: The present disclosure discloses a multichannel PIM digital cancellation circuit, including a first frequency-shift variable rate module, a second frequency-shift variable rate module, a first conversion circuit, a second conversion circuit, a duplexer, a second transmission duplexer, a channel combiner, a third conversion circuit, a cascaded filter circuit, a PIM canceller, a feedback circuit, and a first adder. The cascaded filter circuit compensates for channel responses such as a delay difference or a phase difference generated after a transmit signal passes through a digital domain downlink, a digital-to-analog converter, and an analog domain downlink; the cascaded filter circuit simulates a group delay unevenness characteristic of the duplexer in the multichannel PIM digital cancellation circuit; a cascaded filter fits an S parameter of the channel combiner in the multichannel PIM digital cancellation circuit, and precisely fits a combining process of the channel combiner in a digital domain, so that a signal capable of canceling a PIM interference signal of a multi-transmission and multi-reception inter-mediate radio frequency system that includes the channel combiner is finally generated in the present disclosure.
