CA 2624410

An intermediate service provider operates to mediate communications between mobile terminals and various service providers. In one embodiment, the intermediate service provider and a given mobile terminal establish a persistent session supported by a logical communication channel that is used to convey communications for all of the various service applications implemented by the mobile terminal, i.e., a single, multiplexed channel. In another embodiment, common command subsystems are used to support the multiple service applications, thereby reducing overhead resulting from multiple protocol headers. In yet another embodiment, establishment of communications with various service providers begins with a single connection request message that specifies at least two selected service applications such that the intermediate service provider can establish communications with the multiple service providers in response to the single connection request message.

Un fournisseur intermédiaire de services assure la transmission des communications entre des appareils mobiles et différents fournisseurs de services. Ce modèle peut prendre diverses formes : par exemple, un fournisseur intermédiaire de services et un appareil mobile établissent une session persistante par l'intermédiaire d'un canal de communication logique assurant la transmission des données pour les diverses applications de service mises en ouvre dans l'appareil mobile (en d'autres termes, la voie de communication constitue un canal unique à multiplexage). Sous une autre forme, des sous-systèmes de contrôle commun sont utilisés pour prendre en charge de multiples applications de service, ce qui permet de réduire le nombre d'en- têtes de protocole et, par conséquent, le volume de données de supervision à transmettre. Dans une autre forme encore, l'établissement des connexions avec différents fournisseurs de services commence par la transmission d'une demande de connexion unique spécifiant au moins deux applications de service particulières, pour permettre au fournisseur intermédiaire de services d'établir des canaux de communication avec plusieurs fournisseurs de services en réponse au message de demande de connexion.
