Title
(EN) CONGESTION CONTROL ACROSS DIFFERENT PUBLIC LAND MOBILE NETWORKS
(FR) CONTRÔLE DE CONGESTION DANS DIFFÉRENTS RÉSEAUX MOBILES TERRESTRES PUBLICS
Abstract
(EN)
Systems, methods, and devices provide for congestion control across different PLMNs. An SMF processes a NAS session management (SM) request message from a UE. The NAS SM request message is associated with a S-NSSAI. In response to determining that the S-NSSAI is congested, the SMF generates a NAS SM response message for the UE. The NAS SM response message includes an indication of a PLMN and an SM back-off time value corresponding to the S-NSSAI. The UE decodes the NAS SM response message and associates the SM back-off time value for use with the PLMN. The UE waits (backs-off) until the SM back-off time is stopped or expires before initiating a session management procedure for the S-NSSAI in the indicated PLMN. However, if the UE selects another PLMN not included in the indicated list of PLMNs, the UE need not back-off and can initiate SM procedures for the S-NSSAI.

Des systèmes, des procédés, et des dispositifs permettent un contrôle de congestion dans différents PLMN. Un SMF traite un message de demande de gestion (SM) de session NAS en provenance d'un UE. Le message de demande de SM NAS est associé à un S-NSSAI. En réponse à la détermination que le S-NSSAI est congestionné, le SMF génère un message de réponse SM NAS pour l'UE. Le message de réponse SM NAS comprend une indication d'un PLMN et une valeur de temps d'attente SM correspondant au S-NSSAI. L'UE décode le message de réponse SM NAS et associe la valeur de temps d'attente SM à utiliser avec le PLMN. L'UE patiente (attend) jusqu'à ce que le temps d'attente SM soit arrêté ou expire avant d'initier une procédure de gestion de session pour le S-NSSAI dans le PLMN indiqué. Cependant, si l'UE sélectionne un autre PLMN non inclus dans la liste indiquée de PLMN, l'UE n'a pas besoin d'attendre et peut initier des procédures SM pour le S-NSSAI.
