Patent

CA 2396769

A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call).

L'invention concerne un procédé et un appareil permettant de demander des instances de protocoles PPP provenant d'un réseau de services de données en paquets, lesdits procédé et appareil comprenant une station mobile configurée pour envoyer un message d'émetteur à un noeud de services de données en paquets (PDSN) auquel ledit message est arrivé après avoir quitté le voisinage d'un autre PDSN. Le message informe le nouveau PDSN du nouvel emplacement de la station mobile et indique à la fois le nombre d'instances de protocole PPP inactives liées à la station mobile et un identificateur de références de services pour chaque instance de protocole PPP. Un signal à l'intérieur du message peut être utiliser pour indiquer si les instances du protocole PPP sont inactives (par exemple, si la station mobile est occupée avec un appel).
