Title (EN) METHOD RELATED TO GPRS (GENERAL PACKET RADIO SERVICE) SYSTEM PROVIDING PACKET SWITCHED CONNECTIONS

Abstract:
(EN) The present invention relates to a method related to GPRS (General Packet Radio Service) system providing packet switched connections throughout a communication network, especially a PLMN (Public Land Mobile Network), said connections being related to different QoS (Quality of Service) levels between end users, wherein an LLC (Logic Link Control) protocol is a packet oriented protocol, and wherein an LLC (Logic Link Control) is established when one mobile station activates one PDP context with a QoS for which the MS (Mobile Station) does not already have an LLC established, and in order to avoid separate handling of several logic links for one mobile station, and in order to avoid assignment of new link identities internally within an SGSM and at change of SGSN, it is according to the present invention suggested that the method involves the use of one LLC (Logic Link Control) with an independent set of link state variables per QoS, so as to allow independent handling of different QoS within said link.
(FR) La présente invention concerne un procédé relatif au système GPRS (service de radiocommunication générale par paquets) fournissant des connexions à commutation par paquets via un réseau de communication, notamment un RMTP (réseau mobile terrestre public). Ces connexions correspondent à différents niveaux de qualités de service (QoS) parmi les utilisateurs finaux. Selon ce procédé, un protocole de commande de liaison logique (CLL) est un protocole orienté paquet et une CLL est établie lorsqu'une station mobile active un contexte PDP avec une qualité de service (QoS) pour laquelle cette station mobile (MS) n'a pas encore de CLL établie. Pour éviter la gestion séparée de plusieurs liaisons logiques pour une même station mobile ainsi que l'affectation de nouvelles identités de liaisons dans un noeud support GPRS de départ (SGSN) et lors du changement de SGSN, la présente invention suggère que le procédé comprenne l'utilisation d'une commande de liaison logique disposant d'un ensemble indépendant de variables d'états de liaison par qualité de service, de manière à autoriser une gestion indépendante de différentes qualités de services dans cette liaison.
