A central terminal may receive from a user a first message, which may be transmitted from a communication terminal, identifying particular media content on a particular content server, and in response the central terminal may transmit a second message to a particular application server if the central terminal determines that the first 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 a particular system, such as IP Multimedia Subsystem (IMS), thereby making use of filtering features of the particular system for user authentication and access control, and obviating need for separate proprietary access control mechanisms for the content server.
