Abstract

La présente demande concerne un procédé de communication et un appareil de communication. Un dispositif de réseau configure, pour un premier type de dispositif terminal, une première valeur et une seconde valeur pour un premier temporisateur de sorte que le premier type de dispositif terminal peut sélectionner, durant l'établissement, la reconstruction ou la récupération d'une connexion RRC avec le dispositif de réseau, une valeur plus appropriée parmi la première valeur et la seconde valeur en tant que valeur du premier temporisateur. Par exemple, la plus grande valeur parmi la première valeur et la seconde valeur est utilisée en tant que valeur du premier temporisateur. Par conséquent, une solution est fournie pour réduire la probabilité de défaillance de l'établissement, de la reconstruction ou de la récupération d'une connexion RRC en raison d'une collecte d'énergie réalisée par un dispositif terminal durant l'établissement ou la reconstruction ou la récupération de la connexion RRC.
