Method and apparatus for SIP user agent discovery of configuration server
First Claim
1. A method by which a telecommunication terminal (10) discovers a Service Configuration Server (17) able to provide access to configuration information needed by the terminal (10) in performing Session Initiation Protocol (SIP) signalling to a multimedia enabling system (13) having a home service proxy (14) and a SIP outbound proxy (12), the method characterized by:
- steps (21) in which the terminal (10) creates and transmits to the SIP outbound proxy (12) for routing to the home service proxy (14) a SIP SUBSCRIBE request for a configuration event package, including in the request its own uniform resource identifier (URI) in the request URI.

Abstract
A method and equipment by which a telecommunication terminal (10) discovers (and may enroll with) a Service Configuration Server (17) having (at least links to) configuration information needed by the terminal in performing Session Initiation Protocol (SIP) signalling to a multimedia enabling system (13) having a home service proxy (14) and an SIP outbound proxy (12), the method including: a step (20) in which the home service proxy obtains a configuration event filter for the terminal; the method characterized by: a step (21) in which the terminal creates and transmits to the SIP outbound proxy for routing to the home service proxy a SIP SUBSCRIBE request for a configuration event package, including in the request its own uniform resource identifier (URI) in the request URI. The home service proxy then redirects the SIP SUBSCRIBE request to the Service Configuration Server based on the configuration event filter for the terminal.

6. A terminal (10) equipped for Session Initiation Protocol (SIP) signalling to a multimedia enabling system (13) having a SIP outbound proxy (12) and a home service proxy (14), the terminal (10) adapted to discover an address and port for a Service Configuration Server (17) able to provide access to configuration information needed by the terminal (10) in performing the SIP signalling, the terminal (10) characterized by:
means (21) by which the terminal (10) creates and transmits to the SIP outbound proxy (12) for routing to the home service proxy (14) a SIP SUBSCRIBE request for a configuration event package, including in the request its own uniform resource identifier (URI) in the request URI. - View Dependent Claims (7)
