Abstract

L'invention porte sur un procédé de commande de transmission/réception de données d'un terminal de communication du type machine (MTC). Après qu'un terminal MTC a été détaché, une entité de gestion de mobilité (MME) effectue une synchronisation sur le terminal MTC. Durant la période de synchronisation, la MME refuse que le terminal MTC soit rattaché à un réseau. L'invention porte en outre sur un système correspondant au procédé suscité, et sur un autre procédé et système de commande de transmission/réception de données d'un terminal MTC. Selon les solutions de la présente invention, le terminal MTC qui ne reçoit pas ni ne transmet des données fréquemment est autorisé à ne pas être rattaché au réseau durant des intervalles de transmission/réception de données, et la transmission/réception de données est effectué strictement conformément aux intervalles de transmission/réception de données, ce qui évite l'occupation de ressources réseau. Selon une variante, le terminal MTC rattaché au réseau dans les intervalles de transmission/réception de données est facturé à un tarif différent, de manière à ce que le terminal MTC qui ne reçoit pas ni ne transmet des données fréquemment effectue une transmission/réception de données conformément aux intervalles de transmission/réception de données dans la mesure du possible, ce qui assure les intérêts de l'opérateur dans la mesure maximale.
