Title (EN) SERVICE ARCHITECTURE FOR SESSION INITIATION PROTOCOL STACK
(FR) ARCHITECTURE DE SERVICE POUR PILE PIS
Abstract: front page image
(EN)This invention concerns architecture for a SIP stack that enables the addition or removal of new services without this having any impact on the other part of the stack. The user agent class contains sessions, the session class contain transactions and service implementations, while the transaction class simply contains service implementations. The user-agent class is programmed to retrieve session service implementations from the application and to attach them to session instances. The session class is programmed to receive transaction service implementations from the application, via the user agent class and to attach them to transaction instances. The proposed architecture allows an application to simultaneously support more than one version of a specific service. Added benefits also include making the customization process of these services quite easy.
(FR)L'invention concerne l'architecture d'une pile PIS permettant d'additionner ou de retirer de nouveaux services sans avoir le moindre impact sur une autre partie de la pile. La catégorie agent utilisateur contient des sessions, la catégorie de sessions contient des transactions et des applications de service. La catégorie de transactions ne contient que des applications de services. Cette catégorie agent-utilisateur est programmée afin de récupérer des applications de services de sessions à partir de l'application et de les fixer aux instances de sessions. La catégorie de sessions est programmée afin de recevoir des applications de services de transactions à partir de l'application, par la catégorie agent utilisateur et de les associer aux instances de transactions. L'architecture proposée permet à une application de supporter simultanément plus d'une version d'un service spécifique. La présente invention présente également l'avantage de rendre le procédé d'individualisation de ces services relativement simple.
