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 for interworking between a first network and a second network, the data forwarding method comprising:
- receiving, by a session management function device from an access and mobility management function device in the second network, information about a bearer in the first network, wherein the session management function device integrates a packet data network gateway-control plane in the first network and a session management function in the second network;
- determining, by the session management function device, a first flow in the second network based on the information about the bearer and association information, wherein the first flow is for data forwarding in the second network, and wherein the association information indicates an association between the first flow and the bearer;
- and
- sending, by the session management function device to a second access network device in the second network via the access and mobility management function device, flow information and forwarding information,
- wherein the flow information indicates the first flow, and wherein the forwarding information identifies a user plane function device for forwarding the first flow to a tunnel corresponding to the bearer.
