Abstract
A Call Session Control Function (CSCF) unit may receive from a user a Session Initiation Protocol (SIP) message, which may be transmitted via a communication terminal, identifying particular media content on a particular content server, and in response the CSCF unit may transmit a second message to a particular application server (SIP-AS) if the CSCF unit determines that the SIP message is associated with the application server. The application server may generate and transmit to the communication terminal accessing information that may be used by the user to retrieve, via the communication terminal, the media content from the content server. Submitting content requests in this manner may enable routing content requests through an IP Multimedia Subsystem (IMS), thereby making use of filtering features of the IMS for user authentication and access control, and obviating need for separate proprietary access control mechanisms for the content server.
