Abstract

Cette invention se rapporte à un système de communication mobile qui permet une communication en temps réel via une interface utilisateur entre un utilisateur et un ou plusieurs autres utilisateurs, cette communication étant également connue sous le terme de 'chat' ou conversation par ordinateur. L'interface utilisateur est disposée dans une station client et fonctionne selon une application (par exemple une mini-application Java) dans la station client. L'utilisateur peut vérifier la disponibilité de multiples 'camarades de conversation', pour participer à une communication simultanée en temps réel dans un groupe sur un mode de communication individuel. Ainsi, les messages peuvent être échangés instantanément entre plusieurs utilisateurs en temps réel via HTTP. Les camarades de conversation disponibles sont affichés dans une 'liste de camarades de conversation' et un sondage d'informations est réalisé périodiquement à partir d'un serveur de 'chat' qui gère les communications entre l'utilisateur et au moins un camarade de conversation. Ce sondage est réalisé à un débit qui est basé au moins partiellement sur le fait de savoir si l'utilisateur est effectivement en train de converser. Le débit de régénération est optimisé pour réduire au minimum le trafic réseau, tout en maximisant le débit de régénération pendant les périodes d'utilisation intense.
