A multipath data transmission method and device are provided, where a multipath proxy client and a multipath proxy gateway establish at least two multipath data subflows based on a first internet protocol (IP) address, and perform multipath data subflow data transmission. Based on the first IP address for establishing the at least two multipath data subflows between the multipath proxy client and the multipath proxy gateway, the multipath proxy gateway establishes a TCP connection to and performs TCP-based data transmission with an application server to be accessed by the multipath proxy client. MPTCP-based multipath data transmission based on IP address information of the multipath proxy client is implemented through proxy of the multipath proxy client and the multipath proxy gateway.

Multipath data transmission method and device

A multipath establishment method and apparatus which relate to the field of communications technologies. The method includes: performing identity authentication on a terminal that accesses a first network via a first network access device, where the first network implements communication by using a base station; performing an admission check on the terminal that accesses a second network via a second network access device; and after both the identity authentication and the admission check of the terminal succeed, establishing a first path between the terminal and a service server via the first network, and establishing a second path between the terminal and the service server via the second network, where the first path and the second path are used to perform data transmission between the terminal and the service server.
