Title (EN) TECHNIQUES AND APPARATUSES FOR QUICK RELEASE OF RADIO RESOURCE CONTROL CONNECTION AFTER SESSION TERMINATION
(FR) TECHNIQUES ET APPAREILS DESTINÉS À UNE LIBÉRATION RAPIDE DE CONNEXION DE COMMANDE DE RESSOURCE RADIO APRÈS 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) Certains aspects de la présente invention concernent généralement une communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut transmettre un message de demande de service étendu (ESR) à une station de base sur la base d'au moins en partie d'une détermination selon laquelle une session de l'UE a été terminée, la session utilisant une première technologie d'accès radio (RAT). L'UE peut recevoir un message de redirection donnant ordre à l'UE de commuter vers une seconde RAT sur la base au moins en partie d'une 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 comprenant une indication selon laquelle l'UE ne nécessite pas de porteuse. De nombreux autres aspects sont fournis.
