Abstract

Disclosed is an event notification system and a method to operate an event notification system that has servers and a subscriber unit. The method includes sending a subscription request message from the subscriber unit to a discovery server, where the subscription request message includes a discovery query, and responsive to a receipt of the subscription request message, parsing the discovery query and accepting the subscription request if the discovery query is supportable by the discovery server. The method further includes formulating a context query based on the parsed discovery query andsending the context query to a context query server. The context query server parses the context query and returns in response identifications of a plurality of event servers that form a community ofevent servers that together determine a result of the discovery query. The discovery server subscribes to the availability of each of the event servers that form the community of event servers, and notifies the subscriber unit of available services that are discovered.

Description

[0001] This application was filed by Nokia Corporation on June 15, 2005, with the application number 200580025757.5, and the title of the invention is "A method, system and computer program for supporting discovery of services and content based on SIP events in a community built on contextual information" A divisional application of one case. technical field [0002] The present invention relates generally to wireless communication systems and methods, and more particularly to wireless terminals and wireless network nodes using the Session Initiation Protocol (SIP). Background technique [0003] The basic architecture of the Session Initiation Protocol (SIP) is defined in IETF RFC3261 (Rosenberg et al., June 2002). In general, SIP is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. The session may include Internet telephony calls, multimedia distributions, and multimedia conferences. A SIP IN...
