Abstract

L'invention concerne un procédé et un dispositif de traitement de service, une puce et un programme d'ordinateur. Le procédé peut comprendre : si une première opération doit être effectuée, le déclenchement par une première station de base d'une première opération lorsqu'un premier instant de déclenchement est atteint ou la commande à un appareil terminal de déclencher une première opération lorsqu'un premier instant de déclenchement est atteint, de façon à modifier une station de base ou une cellule desservant une connexion correspondant à un premier service, la première opération étant déclenchée et exécutée dans une période de non-transmission de données associée au premier service. La solution de la présente invention peut empêcher l'interruption de la transmission de premières données de service, ce qui permet de garantir un fonctionnement normal du premier service.
