Document Type and Number:

Japanese Patent JP7181990

Kind Code:

B2

Abstract:

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.
