Abstract

La présente invention concerne, dans ses différents modes de réalisation, des procédés et dispositifs de régulation de l'encombrement. Le procédé de régulation de l'encombrement comporte les étapes suivantes : un élément de gestion de la mobilité obtient un message de demande envoyé par un dispositif d'utilisateur, l'élément de gestion de la mobilité ou d'autres dispositifs de réseau étant en état d'encombrement ; l'élément de gestion de la mobilité envoie une information d'indication d'attente de télé-avertissement au dispositif d'utilisateur. En vertu des modes de réalisation de la présente invention, lorsque l'élément de gestion de la mobilité ou d'autres dispositifs de réseau sont en état d'encombrement, l'élément de gestion de la mobilité peut indiquer au dispositif d'utilisateur d'arrêter d'envoyer des messages de signalisation au réseau et d'attendre un télé-avertissement provenant du réseau, réduisant ainsi la quantité de signalisation sur le réseau avant une solution efficace de la situation d'encombrement tout en évitant des pannes de dispositifs de réseau dues à l'impact de la signalisation et en garantissant une exploitation normale des services de communications.
