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

摘要

A system and associated method for subscribing Really Simple Syndication (RSS) enabled content using the Session Initiation Protocol (SIP) are disclosed. An application server coupled to a Hypertext Transfer Protocol (HTTP) server in the Internet intermediates a SIP message and a request for a RSS feed. An end device requests subscription of the RSS feed in a SIP message. The HTTP server enables the application server to subscribe the RSS feed and to track changes in the RSS feed over the Internet by use of a Serving Call/Session Control Function (S-CSCF) servicing the SIP message. The HTTP server enables the end device subscribing the RSS feed to fetch the web content from the media cache in later part of the subscription by providing updates to the application server.
