Abstract: The present invention relates to the field of communications technologies and discloses service transmission methods, apparatus, and devices. In one embodiment, a method includes: obtaining, by a target server or user equipment, an Internet Protocol (IP) address assigned by a target gateway to the user equipment; establishing a Multipath Transmission Control Protocol (MPTCP) connection between the user equipment and the target server based on the IP address assigned by the target gateway to the user equipment, where the MPTCP connection between the user equipment and the target server and an MPTCP connection between the user equipment and a source server are bound to a same MPTCP session; and transmitting a service data packet using the MPTCP connection between the user equipment and the target server. The service data packet is transmitted using the target gateway so a transmission path is optimized and a service transmission delay is reduced.
