The method includes: receiving an Invite message sent by an IMS network element, where the Invite message carries called identifying information; when a called terminal identified by the called identifying information is a CS network user, generating a CR parameter or a GCR parameter, and generating a CS call reference header field according to the CR parameter or the GCR parameter, and sending a response message to the IMS network element, where the message carries the CS call reference header field to identify a call corresponding to the Invite message. The present invention implements that cross-domain call association by using a unified call reference parameter identifier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Call identifying method and apparatus","description":"The present invention relates to a call identifying method and apparatus.
