Abstract

La présente invention concerne un procédé et un dispositif de traitement de recherche de téléphone mobile. Le procédé comprend les étapes au cours desquelles : un équipement de réseau central transmet des informations d'identification à une passerelle de desserte, les informations d'identification étant utilisées pour stocker une identification d'une zone dans laquelle un objet de recherche de l'équipement de réseau central est situé ; après un redémarrage de l'équipement de réseau central ou une interruption d'une liaison, l'équipement de réseau central reçoit les informations d'identification provenant de la passerelle de desserte ; et l'équipement de réseau central effectue une recherche sur un terminal dans la zone correspondant à l'identification de zone en fonction des informations d'identification. La présente invention règle les problèmes associés aux techniques apparentées et dus au fait qu'une MME ne peut pas obtenir d'informations de liste TAI pour effectuer la recherche, ce qui se solde par une grande plage de recherche non valable, un gaspillage des ressources radio et un long délai de recherche. Par conséquent, d'après la présente invention, la MME peut effectuer une recherche sur le terminal à l'aide des informations de liste TAI, ce qui permet d'augmenter l'efficacité de recherche.
