CA 2433759

Point-to-point protocol (PPP) negotiation in a wireless communication system between e.g. a mobile station (MS) and a packet data service node (PDSN). The MS sends to the PDSN a link control protocol option designated option X that identifies a user profile including at least one pre-negotiated PPP parameter. If the PDSN supports the user profile and the at least one parameter, it acknowledges this. In response, the MS acknowledges its acceptance. Then each node sets a state machine in accordance with the user profile. If the PDSN supports the user profile but not one or more of the at least one parameter, it sends a negative-acknowledgment identifying a second, acceptable user profile. If the PDSN does not support the user profile, it rejects the first user profile and a full PPP negotiation is performed without reference to any of the pre-stored user profiles.

L'invention se rapporte à une négociation de protocole point à point (PPP) dans un système de communication sans fil entre, par exemple, une station mobile (MS) et un noeud de service de transfert de paquets de données (PDSN). La station mobile envoie au noeud de service PDSN une option de protocole de commande de liaison désignée option X qui identifie un profil utilisateur incluant au moins un paramètre PPP prénégocié. Si le noeud de service PDSN est capable de gérer le profil utilisateur et ledit paramètre, il en accuse réception. En réponse, la station mobile accuse réception de son acceptation. Chaque noeud fixe ensuite son automate fini en fonction du profil utilisateur. Si le noeud de service PDSN peut gérer le profil utilisateur mais pas l'un ou plusieurs des paramètres, il envoie un accusé de réception négatif identifiant un second profil utilisateur acceptable. Si le noeud de service PDSN ne peut pas gérer le profil utilisateur, il rejette le premier profil utilisateur et une négociation PPP totale est mise en oeuvre sans référence à aucun des profils utilisateurs préenregistrés.
