  • TPINs allow an operator to update, upgrade or modify the predetermined sets of TPs without a major undertaking. In the past, the operator would be required to update each subscribers list of TPs. With the use of TPINs, the operator merely needs to redefine the predetermined sets of TPs to include new, modified, or upgraded TPs.

  • VPLMN can be greatly reduced. Third, updating, enhancing and maintaining the trigger parameter information is more efficient.

Abstract

Ce système (100) de communications de réseau intelligent comprend un réseau mobile local (101) ainsi qu'un réseau mobile étranger (103) interconnecté au moyen d'un réseau téléphonique commuté public/réseau numérique à service intégré (105). Chaque réseau mobile (101, 103) comprend un commutateur (109, 121) de communications et des registres (111, 113, 123, 125) d'emplacements, lesquels stockent, entre autres choses, des paramètres de déclenchement (TP) destinés à des abonnés individuels du système de communications (100). Chaque abonné individuel possède un réseau mobile local (101), des informations se rapportant à cet abonné étant stockées dans un registre d'emplacement local (HLR) (111), dans lequel on trouve, entre autres, un nombre d'identification des paramètres de déclenchement (TPIN). Ce nombre (TPIN) identifie un ensemble de paramètres parmi une pluralité d'ensembles de paramètres prédéterminés, lesquels sont disponibles dans le réseau mobile local (101).
