A method and apparatus for automatically discovering and retrieving content based on a content identity (ID) are disclosed. User agents and content control entities in the network interact for registering the content, discovering the content hosts and sources, and initiating and controlling the content session. A content name resolution handler (CNRH) is provided for mapping content IDs to network locations or addresses. Two or more content service provider networks may interconnect each other to discover and retrieve the content. A content request from a client device includes a content ID that uniquely identifies a content object. The content ID is resolved with a CNRH to obtain identity information of at least one content provider for serving the content request, and the content request is forwarded to the selected content provider. The content request may be routed to the selected content provider via IP multimedia subsystem (IMS) control plane entities.
