1. An initiation method, applied by a first communication node, wherein the first communication node is in a connected state, an idle state or an inactive state, and the method comprises:
receiving relay function configuration information sent by a second communication node; and
initiating, according to a comparison result of the relay function configuration information and a first current parameter value, a relay function corresponding to the comparison result, wherein the first current parameter value comprises a measurement value and a traffic priority;
wherein the relay function configuration information comprises: user equipment (UE)-to-network relay function configuration information;
wherein the method further comprises: in a case where the first communication node is in an idle state or an inactive state for cell selection, selecting the second communication node supporting a relay function; and
wherein selecting the second communication node supporting the relay function comprises:
determining, by the first communication node, that the second communication node supports a UE-to-network relay function in at least one of following manners:
receiving a physical random access channel (PRACH) resource dedicated to the UE-to-network relay function within a coverage range of the second communication node; or
receiving an access category and an access identifier which are dedicated to the UE-to-network relay function within the coverage range of the second communication node.
