Title (EN) ESTABLISHING A COMMUNICATIONS SESSION HAVING A QUALITY OF SERVICE IN A COMMUNICATIONS SYSTEM
(FR) ETABLISSEMENT D'UNE SESSION DE COMMUNICATIONS PRESENTANT UNE QUALITE DE SERVICE DANS UN SYSTEME DE COMMUNICATIONS
Abstract: front page image
(EN)A communications system (10) includes a packet-based wireless network linked to mobile units (12) and a circuit-switched network such as a public-switched telephone network (PSTN) (32). A primary Packet Data Protocol (PDP) context is established with call setup that contains the default quality of service (QoS) profile of the call session. However, to support multiple flows with different QoS profiles, secondary PDP contexts with different QoS profiles may be activated in the call session. The secondary PDP context activation may be performed using messaging according to a protocol for reserving resources, such as the Resource Reservation Protocol (RSVP).
(FR)Système de communications (10) qui comprend un réseau sans fil basé sur des paquets et relié à des unités (12) mobiles et un réseau à commutation de circuits tel qu'un réseau téléphonique public commuté (RTPC) (32). Un contexte primaire de protocole de données par paquets (PDP) est établi lors de l'établissement d'une communication et contient le profil de la qualité de service (QoS) par défaut de la session d'appel. Cependant, afin de soutenir plusieurs flux avec des profils de QoS différents, des contextes PDP secondaires avec des profils de QoS différents peuvent être activés au cours de la session d'appel. L'activation des contextes PDP secondaires peut être effectuée au moyen de messages selon un protocole de réserve de ressources, tel que le protocole de réserve de ressources (RSVP).
