Title (EN) LOCAL INTERNET PROTOCOL ACCESS CONNECTION HANDLING DURING CIRCUIT SWITCHED FALLBACK AND HANDOVER
(FR) GESTION D'UNE CONNEXION D'ACCÈS À UN PROTOCOLE INTERNET LOCAL PENDANT UN REPLI ET UN TRANSFERT À COMMUTATION DE CIRCUIT
Abstract: front page image
(EN)A method and apparatus are described for handling local Internet protocol (IP) access (LIPA) connection during circuit switched fallback (CSFB) and handover (HO). One representative method of managing a Local Internet Protocol Access (LIPA) packet data network (PDN) connection to a wireless transmit/receive unit (WTRU), includes performing a switching operation to switch from the LIPA PDN connection to a non-LIPA PDN connection for communication to the WTRU; and suspending the LIPA PDN connection, in response to the switching operation.
(FR)L'invention concerne un procédé et un appareil destinés à gérer une connexion d'accès par protocole Internet (IP) local (IPA, Local Internet Protocol Access) pendant un repli (CSFB, Circuit Switched Fallback) et un transfert (HO, HandOver) à commutation de circuit. Un procédé représentatif pour la gestion de la connexion d'un réseau de données par paquets du type à Accès par Protocole Internet Local (LIPA, Local Internet Protocol Access) (PDN, Packet Data Network) à une unité d'émission/réception sans fil (WTRU, Wireless Transmit-Receive Unit), consiste à effectuer une opération de basculement pour basculer de la connexion au réseau LIPA-PDN à une connexion à un réseau PDN non-LIPA pour communiquer avec l'unité WTRU ; et à suspendre la connexion PDN de type LIPA en réponse à l'opération de basculement.
