1. A method for data forwarding, applied to a first radio access network node and comprising:
sending, a first interface message requesting to modify a node, to a second radio access network node;
receiving a second interface message returned by the second radio access network node, wherein the second interface message comprises first radio resource control (RRC) configuration information and first data forwarding and distribution information, and the first data forwarding and distribution information indicates first data that needs data forwarding, and the first data is a user data flow which needs data forwarding under a condition that data forwarding is able to be performed; and
sending a third interface message carrying the first RRC configuration information and the first data forwarding and distribution information to a third radio access network node, and requesting the third radio access network node to receive the first data forwarded from the second radio access network node;
wherein the first interface message comprises a configuration inquiry instruction for requesting current RRC configuration of the second radio access network node.
