Claim 4:
5. The method according to claim 4, wherein the selecting the target interface function network element based on the capability information comprises:
if the capability information indicates that the access and mobility management function network element is capable of performing signaling transmission with the radio access network through the non-service-oriented interface function network element, selecting, by the first network element, the non-service-oriented interface function network element as the target interface function network element;
if the capability information indicates that the access and mobility management function network element is capable of performing signaling transmission with the radio access network through the radio network management function network element, selecting, by the first network element, the radio network management function network element as the target interface function network element; or
if the capability information indicates that the access and mobility management function network element is capable of performing signaling transmission with the radio access network through at least one of the non-service-oriented interface function network element or the radio network management function network element, selecting, by the first network element, the non-service-oriented interface function network element or the radio network management function network element as the target interface function network element.
