Abstract: A data flow control method, and related device and communication system are provided. In the solutions of a data flow control, a first gateway receives a first message sent by a user equipment (UE) through a first access network, where the first message carries first Internet Protocol (IP) flow identification information; the first gateway sends a second message to a packet data network gateway, and receives a third message sent by the packet data network gateway, where the third message carries third IP flow identification information, and the third IP flow identification information is used to identify an IP flow that is allowed by a network to be transmitted by the UE through the first access network and/or an IP flow that is allowed by a network to be transmitted by the UE through a second access network; and the first gateway sends a fourth message to the UE.

Abstract: In the embodiments of the invention, a user equipment sends an I1 Invite message to a service centralization and continuity application server. The I1 Invite message includes a service control switching request indication and a Session Initiation Protocol (SIP) dialog identifier of an Internet Protocol multimedia subsystem (IMS) session. The service centralization and continuity application server searches for the IMS session according to the SIP dialog identifier, and sends a message indicating that a service control is switched to the user equipment.
