Abstract

Divers aspects de la présente invention concernent généralement la communication sans fil. Selon certains aspects, un équipement d'utilisateur (UE) peut effectuer une libération forcée de l'UE à partir d'une connexion de gestion des ressources radio (RRC). L'UE peut déterminer une quantité estimée de libérations forcées par l'UE pendant une période antérieure après la réalisation de la libération forcée de l'UE à partir de la connexion RRC. La quantité estimée peut être basée, au moins en partie, sur une fonction qui délivre une valeur maximale d'une pluralité de valeurs. L'UE peut déterminer, sur la base, au moins en partie, de la détermination de la quantité estimée, un laps de temps d'inactivité destiné à déclencher une libération forcée future. Le laps de temps peut être basé, au moins en partie, sur le fait que la quantité estimée dépasse une quantité maximale de libérations forcées autorisées pendant une période. L'invention concerne de nombreux autres aspects.
