Abstract
A communication system includes a packet-based data network that is coupled to various network elements. The network elements include user systems and a service provider system. Each of the user systems may send requests to the service provider system to receive selected categories of information. In response, the service provider system (or alternatively another information provider) transmits the requested information to each subscribing user system, which then presents the information as a ticker. Messaging used for communicating the ticker information may be based on the Session Initiation Protocol (SIP), including Subscribe and Notify messages or Info messages.
