Title (EN) TECHNIQUES AND APPARATUSES FOR QUICK RELEASE OF A RADIO RESOURCE CONTROL CONNECTION AFTER SESSION TERMINATION
(FR) TECHNIQUES ET APPAREILS DE LIBÉRATION RAPIDE DE CONNEXION DE COMMANDE DE RESSOURCE RADIO APRÈS UNE FIN DE SESSION
Abstract:
(EN) Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an extended service request (ESR) message to a base station based at least in part on determining that a session of the UE has been terminated, wherein the session uses a first radio access technology (RAT). The UE may receive a redirection message instructing the UE to switch to a second RAT based at least in part on transmitting the ESR message. The UE may remain camped on the first RAT despite receiving the redirection message. The UE may transmit a tracking area update (TAU) message to the base station while remaining camped on the first RAT, wherein the TAU message includes an indication that the UE does not require a bearer. Numerous other aspects are provided.
(FR) Selon certains aspects, la présente invention se rapporte d'une manière générale à une communication sans fil. Selon certains aspects, l'invention concerne un équipement utilisateur (UE) pouvant transmettre un message de demande de service étendu (ESR) à une station de base sur la base, au moins en partie, de la détermination selon laquelle une session d'UE est terminée, la session utilisant une première technologie d'accès radio (RAT). L'UE peut recevoir un message de redirection ordonnant à l'UE de passer sur une seconde RAT sur la base, au moins en partie, de la transmission du message ESR. L'UE peut rester en attente sur la première RAT malgré la réception du message de redirection. L'UE peut transmettre un message de mise à jour de zone de suivi (TAU) à la station de base tout en restant en attente sur la première RAT, le message TAU indiquant que l'UE ne nécessite pas de dispositif de prise en charge. L'invention concerne également de nombreux autres aspects.
