Abstract
A data forwarding method includes receiving, by a session management function network element, information about a first bearer in a first network from an access and mobility management function network element; and sending flow information of a first flow in a second network and forwarding information to the access and mobility management function network element. The flow information indicates a flow for data forwarding, and the forwarding information is used for forwarding the first flow to a tunnel corresponding to the first bearer.
Claims20
A data forwarding method, comprising:
- sending, by an access and mobility management function device to a session management function device, information about a first bearer in a first network;
- receiving, by the session management function device, the information about the first bearer;
- sending, by the session management function device to the access and mobility management function device, flow information of a first flow in a second network and forwarding information, wherein the flow information indicates the first flow for data forwarding, and wherein the forwarding information is for forwarding the first flow to a tunnel corresponding to the first bearer;
- receiving, by the access and mobility management function device, the flow information and the forwarding information;
- and
- sending, by the access and mobility management function device to an access network device in the second network, the flow information and the forwarding information.
A data forwarding system, comprising:
- an access and mobility management function device configured to send information about a first bearer in a first network;
- and
- a session management function device configured to:
- receive the information about the first bearer;
- and
- send, to the access and mobility management function device, flow information of a first flow in a second network and forwarding information, wherein the flow information indicates the first flow for data forwarding, and wherein the forwarding information is for forwarding the first flow to a tunnel corresponding to the first bearer, and
- wherein the access and mobility management function device is further configured to send, to an access network device in the second network, the flow information and the forwarding information.
