System and method for accessing really simple syndication (RSS) enabled content using session initiation protocol (SIP) signaling

A computer program product, comprising a computer usable storage device having a computer readable program code stored therein, said computer readable program code containing instructions that when executed by a processor of a computer system implement a method for tracking web content serviced by a Hypertext Transfer Protocol (HTTP) server in the Internet to feed an end device coupled to an Internet Protocol (IP) Multimedia Subsystem (IMS), wherein the web content is summarily represented by an Really Simple Syndication (RSS) document accessible by the HTTP server, wherein the IMS comprises an application server and a media cache, wherein the application server processes both the RSS document and a Session Initiation Protocol (SIP), wherein the application server is coupled to the HTTP server of the Internet outside of the IMS, said method comprising:

• said processor retrieving, by the HTTP server, the web content responsive to receiving a request for metadata of the web content from the end device;
• and
• said processor relaying the retrieved web content to the end device such that the end device subsequently sends a SIP SUBSCRIBE request for the RSS document and the web content to the application server for subscription by use of the relayed web content, wherein the RSS document and the web content is serviced by the HTTP server.

A computer system comprising a processor and a computer readable memory unit coupled to the processor, said memory unit containing instructions that when executed by the processor implement a method for tracking web content serviced by a Hypertext Transfer Protocol (HTTP) server in the Internet to feed an end device coupled to an Internet Protocol (IP) Multimedia Subsystem (IMS), wherein the web content is summarily represented by an Really Simple Syndication (RSS) document accessible by the HTTP server, wherein the IMS comprises an application server and a media cache, wherein the application server processes both the RSS document and a Session Initiation Protocol (SIP), wherein the application server is coupled to the HTTP server of the Internet outside of the IMS, said method comprising:

• said processor retrieving, by the HTTP server, the web content responsive to receiving a request for metadata of the web content from the end device;
• and
• said processor relaying the retrieved web content to the end device such that the end device subsequently sends a SIP SUBSCRIBE request for the RSS document and the web content to the application server for subscription by use of the relayed web content, wherein the RSS document and the web content is serviced by the HTTP server.
